+ * generic/tcl.h: [Bug 2800740]: Changed the typedef for the

+ to:
+ typedef unsigned int mp_digit;
+ For 32-bit builds where "long" and "int" are two names for the same
+ thing, this is no change at all. For 64-bit builds, though, this
+ causes the dp[] array of an mp_int to be made up of 32-bit elements
+ instead of 64-bit elements. This is a huge improvement because details
+ elsewhere in the mp_int implementation cause only 28 bits of each

- Windows [file mtime] will now return seconds from the Posix epoch
- correctly (except for FAT32 file systems after a DST change without a
- reboot - for which there is no help). A side effect is that file times
- will appear different in Tcl from the way they do in Windows Explorer

- wrong in the listings.

- * win/tclWinPipe.c: The pipe channel driver now respects the -blocking
- option when closing. The windows pipe driver now has the same behavior
- as the UNIX side. This change is to avoid a hung shell when exiting
- due to open pipes that refuse to close in a graceful manner.
- * doc/open.n: Added a note about -blocking 0 and lack of exit status
- as it had never been documented. [Bug 947693]
+ * library/tm.tcl (::tcl::tm::UnknownHandler): Changed 'source' to
+ 'source -encoding utf-8'. This fixes a portability problem of Tcl
+ Modules pointed out by Don Porter. By using plain 'source' we were at
+ the mercy of 'encoding system', making modules less portable than they
+ could be. The exact scenario: A writes a TM in some weird encoding
+ which is A's system encoding, distributes it, and somewhere else it
+ cannot be read/used because the system encoding is different. Forcing
+ the use of utf-8 makes the module portable.
- ***POTENTIAL INCOMPATIBILITY***
+ ***INCOMPATIBILITY*** for all Tcl Modules already written in non-utf-8
+ compatible encodings.
- Scripts that use async pipes on windows, must (like the UNIX side) set
- -blocking to 1 before calling [close] to receive the exit status.

+ * generic/tclIORChan.c: Fixed a problem with reflected channels. 'chan

+ commands to use it. It identifies the channel by handle. The channel

- 2001-09-26. The fix done at that time is incomplete. It is possible to
- get around it if the actual read operation is defered and not executed
- in the event handler itself. Instead of tracking if we are in an read
- caused by a synthesized fileevent we now track if the OS has delivered
- a true event = actual data and bypass the driver if a read finds that

+ *** POTENTIAL INCOMPATIBILITY *** (tclInt.h and tclCompile.h)
+ Extensions that access internals defined in tclInt.h and/or
+ tclCompile.h may lose both binary and source compatibility. The
+ relevant changes are:
+ 1. 'struct Var' is completely changed, all acceses to its internals
+ (either direct or via the TclSetVar* and TclIsVar* macros) will
+ malfunction. Var flag values and semantics changed too.
+ 2. 'struct Bytecode' has an additional field that has to be
+ initialised to NULL
+ 3. 'struct Namespace' is larger, as the varTable is now one pointer
+ larger than a Tcl_HashTable. Direct access to its fields will
+ malfunction.
+ 4. 'struct CallFrame' grew one more field (the second such growth with
+ respect to Tcl8.4).
+ 5. API change for the functions TclFindCompiledLocal, TclDeleteVars
+ and many internal functions in tclVar.c
+
+ Additionally, direct access to variable hash tables via the standard
+ Tcl_Hash* interface is to be considered as deprecated. It still works
+ in the present version, but will be broken by further specialisation
+ of these hash tables. This concerns especially the table of array
+ elements in an array, as well as the varTable field in the Namespace
+ struct.

+ * generic/tclCompCmds.c (TclCompileWhileCmd):
+ * generic/tclCompile.c (TclCompileScript):
+ Corrected faulty avoidance of INST_START_CMD when the first opcode in

+2007-07-11 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclCompExpr.c: Added a "parseOnly" flag argument to
+ ParseExpr() to indicate whether the caller is Tcl_ParseExpr(), with an
+ end goal of filling a Tcl_Parse with Tcl_Tokens representing the
+ parsed expression, or TclCompileExpr() with the goal of compiling and
+ executing the expression. In the latter case, more aggressive
+ conversion of QUOTED and BRACED lexeme to literals is done. In the
+ former case, all such conversion is avoided, since Tcl_Token
+ production would revert it anyway. This enables simplifications to the
+ GenerateTokensForLiteral() routine as well.
+
+2007-07-10 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclCompExpr.c: Added a field for operator precedence
+ to be stored directly in the parse tree. There's no memory cost to
+ this addition, since that memory would have been lost to alignment
+ issues anyway. Also, converted precedence definitions and lookup
+ tables to use symbolic constants instead of raw number for improved
+ readability, and continued extending/improving/correcting comments.
+ Removed some unused counter variables. Renamed some variables for
+ clarity and replaced some cryptic logic with more readable macros.

+
+ * generic/tclCompExpr.c: Revision so that the END lexeme never

+ lexeme code commentary.

- makes the source code easier to read. [Patch 561305, 561301]
+2007-04-03 Don Porter <dgp@users.sourceforge.net>
- 2) Revamps how the socket message handler thread is brought up and
- down to allow for cleaner exits without the use of TerminateThread().
- TerminateThread is evil. No attempt has been made to resolve [Bug
- 593810] which may need a new channel driver version for adding a
- registering function within the transfered thread to init the handler
- thread. IOW, initialization of the TSD structure is getting bypassed
- through the thread extension's [thread::transfer] command.

+ * generic/tclCompExpr.c: Now that the new internal structs are

- *** macosx-8-4-branch merged into the mainline [Patch 602770] ***
+ * generic/tclBasic.c: Final step routing all direct evaluation forms
+ * generic/tclCompExpr.c: of the operator commands through TEBC,
+ * generic/tclCompile.h: dropping all the routines in tclMathOp.c.
+ * generic/tclMathOp.c: Still needs Engineering Manual attention.
- * generic/tcl.decls: added new macosx specific entry to stubs table.
+2006-12-11 Don Porter <dgp@users.sourceforge.net>
- * tools/genStubs.tcl: added generation of platform guards for macosx.
- This is a little more complex than it seems, because MacOS X IS "unix"
- plus a little bit, for the purposes of Tcl. BUT unfortunately, Tk uses
- "unix" to mean X11. So added platform keys for macosx (the little
- added to "unix"), "aqua" and "x11" to distinguish these for Tk.
+ * generic/tclBasic.c: Another step with all sorting operator
+ * generic/tclCompExpr.c: commands now routing through TEBC via
+ * generic/tclCompile.h: TclSortingOpCmd().
- * generic/tcl.h: added a #ifnded RESOURCE_INCLUDED so that tcl.h can
- be passed to the resource compiler.
+2006-12-08 Don Porter <dgp@users.sourceforge.net>
- * generic/tcl.h:
- * generic/tclNotify.c: added a few Notifier procs, to be able to
- modify more bits of the Tcl notifier dynamically. Required to get Mac
- OS X Tk to live on top of the Tcl Unix threaded notifier. Changes the
- size of the Tcl_NotifierProcs structure, but doesn't move any elements
- around.
+ * generic/tclBasic.c: Another step down the path of re-using
+ * generic/tclCompExpr.c: TclExecuteByteCode to implement the TIP 174
+ * generic/tclCompile.h: commands instead of using a mass of code
+ * generic/tclMathOp.c: duplication. Now all operator commands that
+ * tests/mathop.test: demand exactly one operation are implemented
+ via TclSingleOpCmd and a call to TEBC.
- * unix/tclUnixNotfy.c: moved the call to Tcl_ConditionNotify till
- AFTER we are done mucking with the pointer swap. Fixes cases where the
- thread waiting on the condition wakes & accesses the waitingListPtr
- before it gets reset, causing a hang.
+ * generic/tclCompExpr.c: Revised implementation of TclInvertOpCmd to
+ * generic/tclMathOp.c: perform a bytecode compile / execute sequence.
+ This demonstrates a path toward avoiding mountains of code duplication
+ in tclMathOp.c and tclExecute.c.
- * library/auto.tcl (tcl_findLibrary): added checking the directories
- in the tcl_pkgPath for library files on macosx to enable support of
- the standard Mac OSX library locations
+ * generic/tclCompile.h: Change TclExecuteByteCode() from static to
+ * generic/tclExecute.c: MODULE_SCOPE so all files including
+ tclCompile.h may call it.
- * unix/Makefile.in:
- * unix/configure.in:
- * unix/tcl.m4: added MAC_OSX_DIR. Added PLAT_OBJS to the OBJS: there
- are some MacOS X specific files now for Tcl, and when I get he
- resource & applescript stuff ported over, and restore support for
- FindFiles, etc, there will be a few more. Added LD_LIBRARY_PATH_VAR
- configure variable to avoid having to set all possible LD_LIBRARY_PATH
- analogues on all platforms. LD_LIBRARY_PATH_VAR is "LD_LIBRARY_PATH"
- by default, "LIBPATH" on AIX, "SHLIB_PATH" on HPUX and
- "DYLD_LIBRARY_PATH" on Mac OSX. Added configure option to package Tcl
- as a framework on Mac OSX.
-
- * macosx/tclMacOSXBundle.c (new): support for finding Tcl extension
- packaged as 'bundles' in the standard Mac OSX library locations.
-
- * unix/tclUnixInit.c: added support for findig the tcl script library
- inside Tcl packaged as a framework on Mac OSX.

- instructions.
- - elimination of 103 (!) TclDecrRefCount macros. The different
- instructions now jump back to a common "DecrRefCount zone" at the

- "NEXT_INST_F" and "NEXT_INST_V" that take three params
- (pcAdjustment, # of stack objects to discard, resultObjPtr handling

+ * generic/tclParseExpr.c: Completely new expression parser that

+ corrects reports of stack-blowing crashes parsing long expressions
+ [Bug 906201] and replaces a fundamentally O(N^2) algorithm with an
+ O(N) one [RFE 903765]. The new parser is better able to generate error
+ messages that clearly report both the nature and context of the syntax
+ error [Bugs 1029267, 1381715]. For now, the code for the old parser is
+ still present and can be activated with a "#define OLD_EXPR_PARSER
+ 1". This is for the sake of a clean implementation patch, and for ease
+ of benchmarking. The new parser is non-recursive, so much lighter in
+ stack consumption, but it does use more heap, so there may be cases
+ where parsing of long expressions that succeeded with the old parser
+ will lead to out of memory panics with the new one. There are still
+ more improvements possible on that point, though significant progress
+ may require changes to the Tcl_Token specifications documented for the
+ public Tcl_Parse*() routines.
+ ***POTENTIAL INCOMPATIBILITY*** for any callers that rely on the exact

- is the controlling terminal and is special. Setting it into raw mode
- as is done for other tty's is a bad idea. This is a hackish fix for
- expect [Bug 520624]. The fix has limitation: Tcl_MakeFileChannel
- handles tty's specially too, but is unable to recognize /dev/tty as it
- only gets a file descriptor, and no name for it.

- * win/mkd.bat (removed):
- * win/coffbase.txt (new):
- * win/makefile.bc:
- * win/makefile.vc: Changed the 'setup' target to stop using the

- change to makefile.bc. configure.in nor Makefile.in use it.
+2006-03-17 Andreas Kupries <andreask@activestate.com>
- coffbase.txt will be the master list for our "prefered base addresses"
- set by the linker. This should improve load-time (NT only) by avoiding
- relocations. Submissions to the list by extension authors are
- encouraged.
+ * doc/chan.n: Updated with documentation for the commands 'chan
+ create' and 'chan postevent' (TIP #219).
- Added a 'tidy' target to compliment 'clean' and 'hose' to remove just
- the outputs. Also removed the $(winlibs) macro as it wasn't being
- used.
+ * doc/refchan.n: New file. Documentation of the command handler API
+ for reflected channels (TIP #219).
- Stuff left to do:
- 1) get the winhelp target to stop building in the tools/ directory.
- 2) stop using rmd.bat
- 3) add more dependacy rules.

+2006-03-16 Andreas Kupries <andreask@activestate.com>
- * win/tclAppInit.c: Changed #include "tcl.h" to be tclPort.h to remove
- the raw windows.h include. tclPort.h brings in windows.h already and
- lessens the pre-compiled-header mush and the randomly useless #pragma

- * generic/tcl.h: Better guessing of LP64/ILP32 architecture, but
- now sensitive to presence of (suitable) <limits.h>
+ * generic/tclIOUtil.c (TclGetOpenMode): Added the flag O_APPEND to the

- * win/buildall.vc.bat:
- * win/makefile.vc:
- * win/rules.vc: General clean-ups. Added compiler and linker tests for
- a) the pentium 0x0F errata, b) optimizing (not all have this), and c)
- linker v6 section alignment confusion. All these are tested first to
- make sure any D4002 or LNK1117 warnings aren't displayed. The pentium
- 0x0F errata is a recommended switch. The v5 linker's section alignment
- default is 512, but the v6 linker was changed to 4096 in an attempt to
- speed loading on Win98. I changed the default to always be 512 across
- both linkers, unless linking statically, then 4096 is used for the
- claimed speed effect. Using a 512 alignment saves 12k bytes of dead
- space in the DLL.
+2006-03-15 Vince Darley <vincentdarley@sourceforge.net>
- Added IA64 B-stepping errata switch when the compiler supports it.
+ * win/fCmd.test: add proper test constraints so the new tests don't

- Added profiling to $(lflags) when requested and also removed the
- explict -entry option as the default works fine as is.
+2006-03-14 Andreas Kupries <andreask@activestate.com>
- Removed win/tclWinInit.c from the special case section to let it use

- +----------------------+
- | TIP #72 IMPLEMENTED. |
- +----------------------+
-
- There are a lot of changes from this TIP, so please see
- http://tip.tcl.tk/72.html for discussion of backward-compatability
- issues, but the main ones modifications are in:
-
- * generic/tcl.h: New types.
- * generic/tcl.decls: New public functions.
- * generic/tclExecute.c: 64-bit aware bytecode engine.
- * generic/tclBinary.c: 64-bit handling in [binary] command.
- * generic/tclScan.c: 64-bit handling in [scan] command.
- * generic/tclCmdAH.c: 64-bit handling in [file] and [format]
- commands.
- * generic/tclBasic.c: New "wordSize" entry in ::tcl_platform.
- * generic/tclFCmd.c: Large-file support (with many consequences.)
- * generic/tclIO.c: Large-file support (with many consequences.)
- * compat/strtoll.c, compat/strtoull.c: New support functions.
- * unix/tcl.m4, unix/configure: 64-bit support and greatly enhanced
- cacheing.
-
- Most other changes, including all those in doc/* and test/* as well as
- the majority in the platform directories, follow on from these.
-
- Also coming out of the woodwork:
- * generic/tclIndex.c: Better support for Cray PVP.
- * win/tclWinMtherr.c: Better Borland support.
-
- Note that, in a number of places through the Unix part of the platform
- support, there are Tcl_Platform* references. These are expanded into
- the correct way to call that particular underlying function, i.e. with
- or without a '64' suffix, and should be used by people working on the
- core in preference to the API functions they overlay so that the code
- remains portable depending on the presence or absence of 64-bit
- support on the underlying platform.
-
- ***POTENTIAL INCOMPATIBILITY***: Extracted from the TIP
-
- SUMMARY OF INCOMPATIBILITIES AND FIXES
- ======================================
-
- The behaviour of expressions containing constants that appear positive
- but which have a negative internal representation will change, as
- these will now usually be interpreted as wide integers. This is always
- fixable by replacing the constant with int(constant).
-
- Extensions creating new channel types will need to be altered as
- different types are now in use in those areas. The change to the
- declaration of Tcl_FSStat and Tcl_FSLstat (which are the new preferred
- API in any case) are less serious as no non-alpha releases have been
- made yet with those API functions.
-
- Scripts that are lax about the use of the l modifier in format and
- scan will probably need to be rewritten. This should be very uncommon
- though as previously it had absolutely no effect.
-
- Extensions that create new math functions that take more than one
- argument will need to be recompiled (the size of Tcl_Value changes),
- and functions that accept arguments of any type (TCL_EITHER) will need
- to be rewritten to handle wide integer values. (I do not expect this
- to affect many extensions at all.)

-
- * generic/tclIOCmd.c (Tcl_GetsObjCmd): Trivial fix for [Bug 517503], a
- memory leak reported by Miguel Sofer <msofer@users.sourceforge.net>.
- The leak happens if an error occurs for "set var [gets $chan]" and
- leak one empty object.

+ -- Summary of changes fixing [Bug 1437595] --
- * unix/configure:
- * unix/tcl.m4: added -pthread for FreeBSD to EXTRA_CFLAGS and
- LDFLAGS. Also triggered nodots only for FreeBSD-3.
- Added AC_DEFINE(_POSIX_PTHREAD_SEMANTICS) for Solaris.
+ * generic/tclEvent.c: Cosmetic touches and identation
+ * generic/tclInt.h: Added TclpFinalizeSockets() call.
- * unix/tclUnixPort.h:
- * unix/tclUnixThrd.c: added thread-safe versions of readdir,
- localtime, gmtime and inet_ntoa for threaded build. (jgdavidson)
+ * generic/tclIO.c: Calls TclpFinalizeSockets() as part of the
+ TclFinalizeIOSubsystem().
- * generic/tclScan.c (Tcl_ScanObjCmd): prevented ckfree being
- called on a pointer to NULL.
+ * unix/tclUnixSock.c: Added no-op TclpFinalizeSockets().
-2002-02-07 Don Porter <dgp@users.sourceforge.net>
+ * win/tclWinPipe.c, win/tclWinSock.c: Finalization of sockets/pipes is
+ now solely done in TclpFinalizeSockets() and TclpFinalizePipes() and
+ not over the thread-exit handler, because the order of actions the Tcl
+ generic core will impose may result in cores/hangs if the thread exit
+ handler tears down corresponding subsystem(s) too early.

- some callers. This change recognizes that Tcl_DStrings are
- de-facto white-box objects.

- (Tcl_StringObjCmd): optimization improvements to the STR_MAP
- algorithm for zero-length and nocase cases.
+2006-03-07 Joe English <jenglish@users.sourceforge.net>
- * tests/regexp.test:

-2002-02-05 Don Porter <dgp@users.sourceforge.net>
+ * unix/Makefile.in: Package http 2.5.2 requires Tcl 8.4, so the

+ * tests/parse.test: simplify TclEvalObjvInternal and to correct
+ the auto-loading of alias targets (parse-8.12). [Bug 1444291]
- * unix/tclUnixChan.c (FileOutputProc): Fixed [bug 465765] reported by
- Dale Talcott <daletalcott@users.sourceforge.net>. Avoid writing
- nothing into a file as STREAM based implementations will consider this
- a EOF (if the file is a pipe). Not done in the generic layer as this
- type of writing is actually useful to check the state of a socket.
+2006-03-03 Don Porter <dgp@users.sourceforge.net>

+ * tests/fileSystem.test: with /../ that lead back to the root
+ of the filesystem, like /foo/.. [Bug 1379287]
- * tests/io.test: io-39.22 split into two tests, one platform

- and TCL_STUB_LIB_PATH to the values of TCL_BUILD_LIB_SPEC,
- TCL_BUILD_STUB_LIB_SPEC, and TCL_BUILD_STUB_LIB_PATH when tclConfig.sh

- it only throws the error for runtime compile, in case the user
- modifies 'string'.
- (TclCompileRegexpCmd): first try at a byte-compiled regexp
- command. It handles static strings and ^$ bounded static strings.
- (TclCompileAppendCmd): made TclPushVarName call always use
- TCL_CREATE_VAR as numWords is always > 2 at that point.
+ * generic/tclDecls.h: make genstubs
+ * generic/tclIntDecls.h:
+ * generic/tclStubInit.c:
- * generic/tclExecute.c (TclExecuteByteCode:INST_LIST): correct

- [Bug 496733]
-
- * generic/tclIO.c (Tcl_GetChannelOption, Tcl_SetChannelOption):

- * generic/tclIO.c (WriteChars): Fix for [Bug 506297], reported by
- Martin Forssen <ruric@users.sourceforge.net>. The encoding chosen in
- the script exposing the bug writes out three intro characters when
- TCL_ENCODING_START is set, but does not consume any input as
- TCL_ENCODING_END is cleared. As some output was generated the
- enclosing loop calls UtfToExternal again, again with START set. Three
- more characters in the out and still no use of input ... To break this
- infinite loop we remove TCL_ENCODING_START from the set of flags after
- the first call (no condition is required, the later calls remove an
- unset flag, which is a no-op). This causes the subsequent calls to
- UtfToExternal to consume and convert the actual input.

- * generic/tclIOCmd.c (Tcl_GetsObjCmd): Fixed [Bug 504642] as reported
- by Brian Griffin <bgriffin@users.sourceforge.net>, using his patch.
- Before the patch the generic I/O layer held an unannounced reference
- to the interp result to store the read line into. This unfortunately
- has disastrous results if the channel driver executes a Tcl script to
- perform its operation, this freeing the interp result. In that case we
- are dereferencing essentially a dangling reference. It is not truly
- dangling because the object is in the free list, but this only causes
- us to smash the free list and have the error occur later somewhere
- else. The patch simply creates a new object for the line and later
- sets it into the interp result when we are done with reading.

- * Tcl variable 'tcl_interactive' is now linked to C variable
- 'tty' so that one can disable/enable interactive prompts at

- meant for use by the test suite.
- * Consistent use of the Tcl libraries standard channels as
- returned by Tcl_GetStdChannel(); as opposed to the channels
- named 'stdin', 'stdout', and 'stderr' in the master interp,
- which can be different or unavailable.
- * Tcl_Main now calls Tcl_Exit() if evaluation of [exit] in the
- master interpreter returns, assuring Tcl_Main does not
- return.
- * Documented Tcl_Main's absence from public stub table
- * Documented that Tcl_Main does not return.

-
- - string compare now takes optional length arg (for strncmp

-
- - added string equal (just a few lines of code blended
- in with string compare)
-
- - added string icompare/iequal for case-insensitive comparisons
-
- - string index's index can now be ?end[+-]?expression
- I made this change in the private TclGetIntForIndex,
- which means that the list commands also benefit, as
- well as string range, et al.
-
- - added [string repeat string count]
- Repeats given string number of times
-
- - added string replace, string equiv to lreplace
- (quasi opposite of string range):
- string replace first last ?string?
- Example of use, replacing end of string with ...
- should the string be more than 16 chars long:
- string replace $string 16 end "..."
- This just returns the string len < 16, so it
- will only affect the long strings.
-
- - added optional first and last args to string to*
- This allows you to just affect certain regions of
- a string with the command (like just capping the
- first letter). I found the original totitle to
- be too draconian to be useful.
-
- - added [string map charMap string]

- can be multiple chars (or none at all). For Tcl/CGI users,

+ - added string equal (just a few lines of code blended in with string
+ compare)
+ - added string icompare/iequal for case-insensitive comparisons
+ - string index's index can now be ?end[+-]?expression
+ I made this change in the private TclGetIntForIndex, which means
+ that the list commands also benefit, as well as string range, et al.
+ - added [string repeat string count]
+ Repeats given string number of times
+ - added string replace, string equiv to lreplace
+ (quasi opposite of string range):
+ string replace first last ?string?
+ Example of use, replacing end of string with ... should the string
+ be more than 16 chars long:
+ string replace $string 16 end "..."
+ This just returns the string len < 16, so it will only affect the
+ long strings.
+ - added optional first and last args to string to*
+ This allows you to just affect certain regions of a string with the
+ command (like just capping the first letter). I found the original
+ totitle to be too draconian to be useful.
+ - added [string map charMap string]
+ where charMap is a {from to from to} list that equates to what one
+ might get from [array get]. Each and can be multiple chars (or none
+ at all). For Tcl/CGI users, this is a MAJOR speed booster.

- - If the variable $tcl_library contains the empty string, this

- it only slows down later package processing.
- - If the variable tcl_pkgPath is not set, the "unset __dir"
- fails. Thich makes init.tcl totally unusable. Better put a "catch"
- around it.
- - In the function tcl_findLibraries, the "string match" function
- only works correctly if $tcl_patchLevel is in one of the forms
- "?.?a?", "?.?b?" or "?.?.?". Could a "regexp" be used instead,
- then it allows anything to be appended to the patchLevel
- string. And it is more efficient.
- - The tclPkgSetup function assumes that if $type != "load" then
- the type must be "source". This needn't be true. Some users want
- to add their own setup types.

+
+ This has a different behavior than unix in that closing the read pipe
+ to a process sends the SIGPIPE signal which is returned as a SIGPIPE

+ get back a CONTROL_C_EXIT which is documented to mean a SIGINT which

+ 1) Cleans-up the winsock typedefs by using the typedefs provided by
+ winsock2.h. This has no effect on how winsock is initialized; just
+ makes the source code easier to read. [Patch 561305 561301]
+
+ 2) Revamps how the socket message handler thread is brought up and
+ down to allow for cleaner exits without the use of TerminateThread().
+ TerminateThread is evil. No attempt has been made to resolve [Bug
+ 593810] which may need a new channel driver version for adding a
+ registering function within the transfered thread to init the handler
+ thread. IOW, initialization of the TSD structure is getting bypassed
+ through the thread extension's [thread::transfer] command.

+ * win/tclWinPipe.c:
+ * win/tclWinSerial.c:
+ * win/tclWinSock.c:
+ * win/tclWinThrd.c:
+ * win/tclWinTime.c: General cleanup of all worker threads used by the
+ channel drivers. Eliminates the normal case where the worker thread is
+ terminated ('cept the winsock one). Instead, use kernel events to
+ signal a clean exit. Only when the worker thread is blocked on an I/O
+ call is the thread terminated. Essentially, this makes all other
+ channel worker threads behave like the PipeReaderThread() function for
+ it's cleaner exit behavior. This appears to fix [Bug 597924] but needs
+ 3rd party confirmation to close the issue.

+2002-11-18 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWinThrd.c (Tcl_CreateThread/TclpThreadExit): Fixed improper
+ compiler macros that missed the VC++ compiler. This resulted in VC++
+ builds using CreateThread()/ExitThread() in place of the proper
+ _beginthreadex()/_endthreadex(). This was a large error and am

+
+2002-11-13 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/regexpComp.test: added tests 22.*

+
+ * generic/tclEncoding.c (UtfToUtfProc, UtfToUnicodeProc):
+ (TableFromUtfProc, EscapeFromUtfProc): Use TclUtfToUniChar.
+ (UnicodeToUtfProc, TableToUtfProc): add 1-byte char optimizations for

+
+ * tests/split.test: added 1-char string split tests
+ * generic/tclCmdMZ.c (Tcl_SplitObjCmd): Use TclUtfToUniChar. Also
+ added a special case for single-ascii-char splits.
+ (Tcl_StringObjCmd): Use TclUtfToUniChar. For STR_RANGE, support
+ getting ranges of ByteArrays (reverts change from 2000-05-26).
+ (TraceExecutionProc) add proper static declaration.
+
+ * generic/tclInt.h: add macro version of Tcl_UtfToUniChar
+ (TclUtfToUniChar) that does the one-byte utf-char check without
+ calling Tcl_UtfToUniChar, for use by the core. This brings notable
+ speedups for primarily ascii string handling.
+
+ * generic/tcl.h (TCL_PATCH_LEVEL): bump to 8.4.1.1 for patchlevel
+ only. This interim number will only be reflected by [info patchlevel].

+
+ * generic/tcl.h:
+ * mac/tclMacApplication.r:
+ * mac/tclMacLibrary.r:

+
+2002-09-10 Mo DeJong <mdejong@users.sourceforge.net>

+
+2002-09-10 Daniel Steffen <das@users.sourceforge.net>
+
+ * macosx/Tcl.pbproj/project.pbxproj: disabled building html
+ documentation during embedded build.
+
+2002-09-10 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/Makefile.in: added DYLIB_INSTALL_DIR variable for macosx and
+ set it to default value ${LIB_RUNTIME_DIR}
+ * unix/tcl.m4 (Darwin): use DYLIB_INSTALL_DIR instead of
+ LIB_RUNTIME_DIR in the -install_name argument to ld.
+ * unix/configure: regen.
+
+ * macosx/Tcl.pbproj/project.pbxproj:
+ * macosx/Makefile: added support for building Tcl as an embedded
+ framework, i.e. using an dyld install_name containing
+ @executable_path/../Frameworks via the new DYLIB_INSTALL_DIR
+ unix/Makefile variable.

+
+ * doc/tcltest.n: Clarified phrasing.
+
+ * generic/tclBasic.c (TclRenameCommand,CallCommandTraces):

+
+2002-09-03 Miguel Sofer <msofer@users.sourceforge.net>

+ TCL_MEM_DEBUG is used. [Bug 583445]
+
+ * win/tclWinConsole.c (ConsoleCloseProc): only wait on writable pipe
+ if there was something to write. This may prevent infinite wait on
+ exit.
+
+ * tests/exec.test: marked exec-18.1 unixOnly until the Windows
+ incompatability (in the test, not the core) can be resolved.
+
+ * tests/http.test (http-3.11): added close $fp that was causing an
+ error on Windows because the file was not closed before deleting.
+
+ * unix/tclUnixInit.c (Tcl_MacOSXGetLibraryPath): made this static
+ function only appear when HAVE_CFBUNDLE is defined.
+
+2002-08-31 Daniel Steffen <das@users.sourceforge.net>

+
+ *** macosx-8-4-branch merged into the mainline [Patch 602770] ***
+
+ * generic/tcl.decls: added new macosx specific entry to stubs table.
+
+ * tools/genStubs.tcl: added generation of platform guards for
+ macosx. This is a little more complex than it seems, because MacOS X
+ IS "unix" plus a little bit, for the purposes of Tcl. BUT
+ unfortunately, Tk uses "unix" to mean X11. So added platform keys for
+ macosx (the little added to "unix"), "aqua" and "x11" to distinguish
+ these for Tk.
+
+ * generic/tcl.h: added a #ifnded RESOURCE_INCLUDED so that tcl.h can
+ be passed to the resource compiler.
+
+ * generic/tcl.h:
+ * generic/tclNotify.c: added a few Notifier procs, to be able to
+ modify more bits of the Tcl notifier dynamically. Required to get Mac
+ OS X Tk to live on top of the Tcl Unix threaded notifier. Changes the
+ size of the Tcl_NotifierProcs structure, but doesn't move any elements
+ around.
+
+ * unix/tclUnixNotfy.c: moved the call to Tcl_ConditionNotify till
+ AFTER we are done mucking with the pointer swap. Fixes cases where the
+ thread waiting on the condition wakes & accesses the waitingListPtr
+ before it gets reset, causing a hang.
+
+ * library/auto.tcl (tcl_findLibrary): added checking the directories
+ in the tcl_pkgPath for library files on macosx to enable support of
+ the standard Mac OSX library locations.
+
+ * unix/Makefile.in:
+ * unix/configure.in:
+ * unix/tcl.m4: added MAC_OSX_DIR. Added PLAT_OBJS to the OBJS: there
+ are some MacOS X specific files now for Tcl, and when I get the
+ resource & applescript stuff ported over, and restore support for
+ FindFiles, etc, there will be a few more. Added LD_LIBRARY_PATH_VAR
+ configure variable to avoid having to set all possible LD_LIBRARY_PATH
+ analogues on all platforms. LD_LIBRARY_PATH_VAR is "LD_LIBRARY_PATH"
+ by default, "LIBPATH" on AIX, "SHLIB_PATH" on HPUX and
+ "DYLD_LIBRARY_PATH" on Mac OSX. Added configure option to package Tcl
+ as a framework on Mac OSX.
+
+ * macosx/tclMacOSXBundle.c (new): support for finding Tcl extension
+ packaged as 'bundles' in the standard Mac OSX library locations.
+
+ * unix/tclUnixInit.c: added support for findig the tcl script library
+ inside Tcl packaged as a framework on Mac OSX.
+
+ * macosx/Tcl.pbproj/jingham.pbxuser (new):
+ * macosx/Tcl.pbproj/project.pbxproj (new): project for Apple's
+ ProjectBuilder IDE.
+
+ * macosx/Makefile (new): simple makefile for building the project from
+ the command line via the ProjectBuilder tool 'pbxbuild'.
+
+ * unix/configure:
+ * generic/tclStubInit.c:
+ * generic/tclPlatDecls.h: regen
+
+2002-08-29 Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+ * win/tclWinThrd.c (TclpFinalizeThreadData, TclWinFreeAllocCache):

+ <msofer@users.sourceforge.net>.
+
+2002-08-28 David Gravereaux <davygrvy@pobox.com>
+
+ * generic/tclEnv.c:
+ * unix/configure.in:
+ * win/tclWinPort.h: putenv() on some systems copies the buffer rather
+ than taking reference to it. This causes memory leaks and is know to
+ effect mswindows (msvcrt) and NetBSD 1.5.2 . This patch tests for this
+ behavior and turns on -DHAVE_PUTENV_THAT_COPIES=1 when approriate.
+ Thanks to David Welton for assistance. [Bug 414910]
+
+ * unix/configure: regen'd
+
+2002-08-28 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * doc/eval.n: Added mention of list command and corrected "SEE ALSO".
+
+ * unix/configure.in: Cache handling of ac_cv_type_socklen_t was wrong.
+ [Bug 600931] reported by John Ellson. Fixed by putting the brackets
+ where they belong.
+
+2002-08-26 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclCompCmds.c: fix for [Bug 599788] (error in element name
+ causing segfault), reported by Tom Wilkason. Fixed by copying the
+ tokens instead of the source string.
+
+2002-08-26 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclThreadAlloc.c: small optimisation, reducing the new
+ allocator's overhead.
+
+2002-08-23 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclObj.c (USE_THREAD_ALLOC): fixed leak [Bug 597936]. Thanks
+ to Zoran Vasiljevic.
+
+2002-08-23 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclThreadAlloc.c (USE_THREAD_ALLOC): moving objects between
+ caches as a block, instead of one-by-one.
+
+2002-08-22 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclBasic.c:
+ * generic/tclCmdMZ.c: fix for freed memory r/w in delete traces [Bug
+ 589863], patch by Hemang Lavana.
+
+2002-08-20 Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+ * win/Makefile.in (CFLAGS):
+ * unix/Makefile.in (MEM_DEBUG_FLAGS): Added usage of @MEM_DEBUG_FLAGS@.
+ * win/configure.in:
+ * unix/configure.in: Added usage of SC_ENABLE_MEMDEBUG.
+ * win/tcl.m4:
+ * unix/tcl.m4: Added macro SC_ENABLE_MEMDEBUG. Allows a user of
+ configure to (de)activate memory validation and debugging
+ (TCL_MEM_DEBUG). No need to modify the makefile anymore.
+
+2002-08-20 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclCkalloc.c: CONSTified MemoryCmd and CheckmemCmd.
+
+ * README: Bumped version number to 8.4b3 to distinguish

+ * tools/tcl.wse.in:
+ * unix/configure.in:
+ * unix/tcl.spec:
+ * win/README.binary:
+ * win/configure.in:
+
+ * unix/configure: autoconf
+ * win/configure:
+
+ * library/http/http.tcl: Corrected installation directory of
+ * library/msgcat/msgcat.tcl: the package tcltest 2.2. Added
+ * library/opt/optparse.tcl: comments in other packages to remind
+ * library/tcltest/tcltest.tcl: that installation directories need
+ * unix/Makefile.in: updates to match increasing version
+ * win/Makefile.in: numbers. [Bug 597450]
+ * win/makefile.bc:
+ * win/makefile.vc:
+
+2002-08-19 Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+ * unix/tclUnixTest.c (TestfilehandlerCmd): Changed readable/writable
+ to the more common readable|writable. Fixes [Bug 596034] reported by
+ Larry Virden <lvirden@users.sourceforge.net>.
+
+2002-08-16 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * tests/fCmd.test: Added test to make sure that the cause of the
+ problem is detectable with an unpatched Tcl.
+ * doc/ObjectType.3: Added note on the root cause of this problem to
+ the documentation, since it is possible for user code to trigger this
+ sort of behaviour too.
+ * generic/tclIOUtil.c (SetFsPathFromAny): Objects should only have
+ their old representation deleted when we know that we are about to
+ install a new one. This stops a weird TclX bug under Linux with
+ certain kinds of memory debugging enabled which essentally came down
+ to a double-free of a string.
+
+2002-08-14 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclInt.h:
+ * generic/tclObj.c: (code cleanup) factored the parts in the macros
+ TclNewObj() / TclDecrRefCount() into a common part for all
+ memory allocators and two new macros TclAllocObjStorage() /
+ TclFreeObjStorage() that are specific to each allocator and fully
+ describe the differences. Removed allocator-specific code from
+ tclObj.c by using the macros.
+
+2002-08-12 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclCmdMZ.c: fixing UMR in delete traces, [Bug 589863].
+
+2002-08-08 David Gravereaux <davygrvy@pobox.com>
+
+ * tools/man2help.tcl: Fixed $argv handling bug where if -bitmap wasn't
+ specified $argc was off by one.
+
+2002-08-08 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * tests/uplevel.test: added 6.1 to test [uplevel] with shadowed
+ commands [Bug 524383]
+
+ * tests/subst.test: added 5.8-10 as further tests for [Bug 495207]
+
+2002-08-08 Don Porter <dgp@users.sourceforge.net>
+
+ * tests/README: Noted removal of defs.tcl.
+
+2002-08-08 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * doc/lsearch.n: corrected lsearch docs to use -inline in examples.
+
+ *** 8.4b2 TAGGED FOR RELEASE ***
+
+ * tests/fCmd.test:
+ * tests/unixFCmd.test: updated tests for new link copy behavior.
+ * generic/tclFCmd.c (CopyRenameOneFile): changed the behavior to
+ follow links to endpoints and copy that file/directory instead of just
+ copying the surface link. This means that trying to copy a link that
+ has no endpoint (danling link) is an error. [Patch 591647] (darley)
+ (CopyRenameOneFile): this is currently disabled by default until
+ further issues with such behavior (like relative links) can be
+ handled correctly.
+
+ * tests/README: slight wording improvements
+
+2002-08-07 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * docs/BoolObj.3: added description of valid string reps for a
+ boolean object. [Bug 584794]
+ * generic/tclObj.c: optimised Tcl_GetBooleanFromObj and
+ SetBooleanFromAny to avoid parsing the string rep when it can be
+ avoided. [Bugs 584650, 472576]
+
+2002-08-07 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclCompile.h:
+ * generic/tclObj.c: making tclCmdNameType static ([Bug 584567], Don
+ Porter).
+
+2002-08-07 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclObj.c (Tcl_NewObj): added conditional code for
+ USE_THREAD_ALLOC; objects allocated through Tcl_NewObj() were
+ otherwise being leaked. [Bug 587488] reported by Sven Sass.
+
+2002-08-06 Daniel Steffen <das@users.sourceforge.net>
+
+ * generic/tclInt.decls:
+ * unix/tclUnixThrd.c: Added stubs and implementations for
+ non-threaded build for the tclUnixThrd.c procs TclpReaddir,
+ TclpLocaltime, TclpGmtime and TclpInetNtoa. Fixes link errors in
+ stubbed & threaded extensions that include tclUnixPort.h and use any
+ of the procs readdir, localtime, gmtime or inet_ntoa (e.g. TclX 8.4)
+ [Bug 589526]
+ * generic/tclIntPlatDecls.h:
+ * generic/tclStubInit.c: Regen.
+
+2002-08-05 Don Porter <dgp@users.sourceforge.net>
+
+ * library/tcltest/tcltest.tcl: The setup and cleanup scripts are now
+ * library/tcltest/pkgIndex.tcl: skipped when a test is skipped, fixing
+ * tests/tcltest.test: [Bug 589859]. Test for bug added, and
+ corrected tcltest package bumped to version 2.2.
+
+ * generic/tcl.decls: Restored Tcl_Concat to return (char *). Like
+ * generic/tclDecls.h: Tcl_Merge, it transfers ownership of a dynamic
+ * generic/tclUtil.c: allocated string to the caller.
+
+2002-08-04 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/CmdCmplt.3: Applied Patch 585105 to fully CONST-ify all
+ * doc/Concat.3: remaining public interfaces of Tcl. Notably,
+ * doc/CrtCommand.3: the parser no longer writes on the string it
+ * doc/CrtSlave.3: is parsing, so it is no longer necessary for
+ * doc/CrtTrace.3: Tcl_Eval() to be given a writable string. Also
+ * doc/Eval.3: the refactoring of the Tcl_*Var* routines by
+ * doc/ExprLong.3: by Miguel Sofer is included, so that the
+ * doc/LinkVar.3: "part1" argument for them no longer needs to
+ * doc/ParseCmd.3: be writable either.
+ * doc/SetVar.3:
+ * doc/TraceVar.3:
+ * doc/UpVar.3: Compatibility support has been enhanced so
+ * generic/tcl.decls: that a #define of USE_NON_CONST will remove
+ * generic/tcl.h: all possible source incompatibilities with the
+ * generic/tclBasic.c: 8.3 version of the header file(s). The new
+ * generic/tclCmdMZ.c: #define of USE_COMPAT_CONST now does what
+ * generic/tclCompCmds.c:USE_NON_CONST used to do -- disable only those
+ * generic/tclCompExpr.c:new CONST's that introduce irreconcilable
+ * generic/tclCompile.c: incompatibilities.
+ * generic/tclCompile.h:
+ * generic/tclDecls.h: Several bugs are also fixed by this patch.
+ * generic/tclEnv.c: [Bugs 584051,580433] [Patches 585105,582429]
+ * generic/tclEvent.c:

+2002-08-01 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c: bugfix (reading freed memory). Testsuite
+ passed on linux/i386, compile-13.1 hung on linux/alpha.
+
+2002-08-01 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c: added a reference count for the complete
+ execution stack, instead of Tcl_Preserve/Tcl_Release.
+
+2002-08-01 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * generic/tclCkalloc.c (TclFinalizeMemorySubsystem): Don't lock the
+ ckalloc mutex before invoking the Tcl_DumpActiveMemory function since
+ it also locks the same mutex. This code is only executed when "memory
+ onexit filename" has been executed and Tcl is compiled with
+ -DTCL_MEM_DEBUG.
+
+2002-08-01 Reinhard Max <max@suse.de>
+
+ * win/tclWinPort.h: The windows headers don't provide socklen_t, so we
+ have to do it.
+
+2002-07-31 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclInt.h (USE_THREAD_ALLOC): for unshared objects,
+ TclDecrRefCount now frees the internal rep before the string rep -
+ just like the non-macro Tcl_DecrRefCount/TclFreeObj [Bug 524802]. For
+ the other allocators the fix was done on 2002-03-06.
+
+2002-07-31 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclInterp.c: signed/unsigned comparison warning fixed
+ (Vince Darley).
+
+2002-07-31 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * unix/tcl.m4 (SC_BUGGY_STRTOD): Enabled caching of test results.
+
+ * unix/tcl.m4 (SC_BUGGY_STRTOD): Solaris 2.8 still has a buggy
+ strtod() implementation; make sure we detect it.
+
+ * tests/expr.test (expr-22.*): Marked as non-portable because it seems
+ that these tests have an annoying tendency to fail in unexpected ways.
+ [Bugs 584825, 584950, 585986]
+
+2002-07-30 Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+ * tests/io.test:
+ * generic/tclIO.c (WriteChars): Added flag to break out of loop if
+ nothing of the input is consumed at all, to prevent infinite looping
+ of called with a non-UTF-8 string. Fixes Bug 584603 (partially). Added
+ new test "io-60.1". Might need additional changes to Tcl_Main so that
+ unprintable results are printed as binary data.
+
+2002-07-29 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/Makefile.in: Use CC_SEARCH_FLAGS instead of LD_SEARCH_FLAGS
+ when linking with ${CC}.
+ * unix/configure: Regen.
+ * unix/configure.in: Don't subst CC_SEARCH_FLAGS or LD_SEARCH_FLAGS
+ since this is now done in tcl.m4.
+ * unix/tcl.m4 (SC_CONFIG_CFLAGS): Document and set CC_SEARCH_FLAGS
+ whenever LD_SEARCH_FLAGS is set. [Patch 588290]
+
+2002-07-29 Reinhard Max <max@suse.de>
+
+ * unix/tcl.m4 (SC_SERIAL_PORT): Fixed detection for cases when
+ configure's stdin is not a tty.
+
+ * unix/tclUnixPort.h:
+ * generic/tclIOSock.c: Changed size_t to socklen_t in
+ socket-related function calls.
+
+ * unix/configure.in: Added test and fallback definition
+ for socklen_t.
+
+ * unix/configure: generated.
+
+2002-07-29 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclObj.c: fixed a comment
+
+ * generic/tcl.h:
+ * generic/tclBasic.c:
+ * generic/tclInterp.c: added the new flag TCL_EVAL_INVOKE to the
+ interface of the Tcl_Eval* functions, removing the
+ TCL_EVAL_NO_TRACEBACK added yesterday: alias invocations not only
+ require no tracebacks, but also look up the command name in the global
+ scope - see new test interp-9.4
+ * tests/interp.test: added 9.3 to test for safety of aliases to hidden
+ commands, 9.4 to test for correct command lookup scope.
+
+2002-07-29 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/regc_locale.c (cclass): [[:xdigit:]] is only a defined
+ concept on western characters, so should not allow any unicode digit,
+ and hence number of ranges in [[:xdigit:]] is fixed.
+ * tests/reg.test: Added test to detect the bug.
+ * generic/regc_cvec.c (newcvec): Corrected initial size value in
+ character vector structure. [Bug 578363] Many thanks to
+ pvgoran@users.sf.net for tracking this down.
+
+2002-07-28 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tcl.h:
+ * generic/tclBasic.c: added the new flag TCL_EVAL_NO_TRACEBACK to the
+ interface of the Tcl_Eval* functions. Modified the error message for
+ too many nested evaluations.
+ * generic/tclInterp.h: changed the Alias struct to be of variable
+ length and store the prefix arguments directly (instead of a pointer
+ to a Tcl_Obj list). Made AliasObjCmd call Tcl_EvalObjv instead of
+ TclObjInvoke - thus making aliases trigger execution traces [Bug
+ 582522].
+ * tests/interp.test:
+ * tests/stack.test: adapted to the new error message.
+ * tests/trace.test: added tests for aliases firing the exec traces.
+
+2002-07-27 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/Makefile.in: Revert fix for Tcl bug 529801 since it was

+ SHLIB_LD_LIBS, CC_SEARCH_FLAGS, LD_SEARCH_FLAGS, and LIB_FILE
+ variables to support more generic library build/install rules.
+ * unix/configure: Regen.
+ * unix/configure.in: Move AC_PROG_RANLIB into tcl.m4. Move shared

+ INSTALL_STUB_LIB rules to deal with the ugly details of running ranlib
+ on static libs at build and install time. Replace TCL_SHLIB_LD_EXTRAS
+ with SHLIB_LD_FLAGS and use it when building a shared library.

+
+ * generic/tclExecute.c, generic/tclCompile.c, generic/tclBasic.c:

+
+2002-07-17 Miguel Sofer <msofer@users.sourceforge.net>

+ * generic/tclInt.h: declare some functions previously local to

+
+2002-07-16 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/Makefile.in: Use dltest.marker file to keep track of when the

+ * generic/tclInt.h:
+ * generic/tclProc.c:
+ Added two Tcl_Obj to the ExecEnv structure to hold the fully qualified

+
+2002-07-15 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclVar.c: refactorisation to reuse already looked-up Var
+ pointers; definition of three new Tcl_Obj types to cache variable name

+ to profit from the caching.
+
+ * generic/tclInt.decls:
+ * generic/tclInt.h:
+ * generic/tclIntDecls.h:
+ * generic/tclNamesp.c: adding CONST qualifiers to variable names

+
+ * tests/set-old.test:

+ * doc/file.n:
+ * win/tclWinFile.c: on Win 95/98/ME the long form of the path is used

+ * doc/Hash.3: Overlooked CONST documentation update.
+
+2002-07-11 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/tclCkalloc.c: ckalloc() and friends take the block size as

+
+2002-07-11 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclCompile.c: now setting local vars undefined at compile

+
+2002-07-11 Donal K. Fellows <fellowsd@cs.man.ac.uk>

+
+ * tests/unixFCmd.test, tests/fileName.test:

+
+ * tests/socket.test: Fixed [Bug 578164]. The original reason for the

+
+ * unix/tcl.m4 (SC_CONFIG_CFLAGS): Made Solaris use gcc for linking
+ when building with gcc to resolve problems with undefined symbols
+ being present when tcl library used with non-gcc linker at later
+ stage. Symbols were compiler-generated, so it is the compiler's
+ business to define them. [Bug 541181]
+
+2002-07-01 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/tcltest.n: more work in progress updating tcltest docs.
+
+ * library/tcltest/tcltest.tcl: Change [configure -match] to stop
+ treating an empty list as a list of the single pattern "*". Changed
+ the default value to [list *] so default operation remains the same.
+
+ * tests/pkg/samename.tcl: restored. needed by pkgMkIndex.test.

+2002-06-30 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/tcltest.n: more work in progress updating tcltest docs.
+
+ * tests/README: Updated the instructions on running and
+ * tests/cmdMZ.test: adding to the test suite. Also updated
+ * tests/encoding.test: several tests, mostly to correctly create
+ * tests/fCmd.test: and destroy any temporary files in the
+ * tests/info.test: [temporaryDirectory] of tcltest.
+ * tests/interp.test:
+
+ * library/tcltest/tcltest.tcl: Stopped checking for writeability of

+
+ * library/tcltest/tcltest.tcl: Fixed [makeFile] and [viewFile] to
+ * tests/cmdAH.test: accurately reflect a file's contents.
+ * tests/event.test: Updated tests that depended on buggy

+
+2002-06-25 Reinhard Max <max@suse.de>
+
+ * unix/tcl.m4: New macro SC_CONFIG_MANPAGES.
+ * unix/configure.in: Added support for symlinks and compression when

+ * unix/mkLinks.tcl: Default is still hardlinks and no compression.
+
+ * unix/mkLinks: generated
+ * unix/configure:
+
+ * unix/README: Added documentation for the new features.
+
+ * unix/tcl.m4 (SC_PATH_TCLCONFIG): Replaced ${exec_prefix}/lib by
+ ${libdir}.
+
+2002-06-25 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/tclUtil.c (TclGetIntForIndex): Fix of critical [Bug 533364]
+ generated when the index is bad and the result is a shared object. The
+ T_ASTO(T_GOR, ...) idiom likely exists elsewhere though. Also removed
+ some cruft that just complicated things to no advantage.
+ (SetEndOffsetFromAny): Same fix, though this wasn't on the path
+ excited by the bug.
+
+2002-06-24 Don Porter <dgp@users.sourceforge.net>
+
+ * library/tcltest/tcltest.tcl: Implementation of TIP 101. Adds abd

+
+2002-06-22 Don Porter <dgp@users.sourceforge.net>
+
+ * changes: updated changes file for 8.4b1 release.
+
+ * library/tcltest/tcltest.tcl: Corrections to tcltest and the Tcl
+ * tests/basic.test: test suite so that a test with options
+ * tests/cmdInfo.test: -constraints knownBug
+ * tests/compile.test: -limitConstraints 1 only tests the
+ * tests/encoding.test: knownBug tests. Mostly involves
+ * tests/env.test: replacing direct access to the

+
+ * unix/Makefile.in: Updated all package install directories

+ * win/makefile.bc: of the packages. Added tcltest package
+ * win/makefile.vc: to installation on Windows.
+
+ * library/init.tcl: Corrected comments and namespace style issues.
+ Thanks to Bruce Stephens. [Bug 572025]
+
+2002-06-21 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * tests/cmdAH.test: Added TIP#99 implementation of 'file
+ * tests/fCmd.test: link'. Supports creation of symbolic and
+ * tests/fileName.test: hard links in the native filesystems and
+ * tests/fileSystem.test: in vfs's, when the individual filesystem

+ * doc/FileSystem.3:
+ * doc/file.n:
+ * mac/tclMacFile.c:

+
+2002-06-20 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclBasic.c (TclEvalObjvInternal): fix for [Bug 571385] in
+ the implementation of TIP#62 (command tracing). Vince Darley, Hemang
+ Lavana & Don Porter: thanks.
+
+2002-06-20 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c (TclCompEvalObj): clarified and simplified the
+ logic for compilation/recompilation.
+
+2002-06-19 Joe English <jenglish@users.sourceforge.net>
+
+ * doc/file.n: Fixed indentation. No substantive changes.
+
+2002-06-19 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tclCmdMZ.c (Tcl_RegexpObjCmd): get the resultPtr again as
+ the Tcl_ObjSetVar2 may cause the result to change. [Patch 558324]
+ (watson)
+
+2002-06-19 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c (TEBC): removing unused "for(;;)" loop;
+ improved comments; re-indentation.
+
+2002-06-18 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c (TEBC):
+ - elimination of duplicated code in the non-immediate INST_INCR
+ instructions.
+ - elimination of 103 (!) TclDecrRefCount macros. The different
+ instructions now jump back to a common "DecrRefCount zone" at the
+ top of the loop. The macro "ADJUST_PC" was replaced by two macros
+ "NEXT_INST_F" and "NEXT_INST_V" that take three params
+ (pcAdjustment, # of stack objects to discard, resultObjPtr handling
+ flag). The only instructions that retain a TclDecrRefCount are
+ INST_POP (for speed), the common code for the non-immediate
+ INST_INCR, INST_FOREACH_STEP and the two INST_LSET.
+
+ The object size of tclExecute.o was reduced by approx 20% since the
+ start of the consolidation drive, while making room for some peep-hole
+ optimisation at runtime.
+
+2002-06-18 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c (TEBC, INST_DONE): small bug in the panic code
+ for tcl-stack corruption.
+
+2002-06-17 David Gravereaux <davygrvy@pobox.com>
+
+ Trims to support the removal of RESOURCE_INCLUDED from rc scripts from
+ [FRQ 565088].
+
+ * generic/tcl.h: moved the #ifndef RC_INVOKED start block up in the
+ file. rc scripts don't need to know thread mutexes.
+
+ * win/tcl.rc:
+ * win/tclsh.rc: removed the #define RESOURCE_INCLUDED to let the
+ built-in -DRC_INVOKED to the work.
+
+2002-06-17 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * doc/CrtTrace.3: Added TIP#62 implementation of command
+ * doc/trace.n: execution tracing [FRQ 462580] (lavana).
+ * generic/tcl.h: This includes enter/leave tracing as well
+ * generic/tclBasic.c: as inter-procedure stepping.

+
+2002-06-17 Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+ * win/tclWinPipe.c (BuildCommandLine): Fixed [Bug 554068] ([exec] on
+ windows did not treat { in filenames well.). Bug reported by Vince
+ Darley <vincentdarley@users.sourceforge.net>, patch provided by Vince
+ too.
+
+2002-06-17 Joe English <jenglish@users.sourceforge.net>
+
+ * generic/tcl.h: #ifdef logic for K&R C backwards compatibility
+ changed to assume modern C by default. See [FRQ 565088] for full
+ details.
+
+2002-06-17 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/msgcat.n: Corrected en_UK references to en_GB. UK is not a
+ country designation recognized in ISO 3166.
+
+ * library/msgcat/msgcat.tcl: More Windows Registry locale codes from
+ Bruno Haible.
+
+ * doc/msgcat.n:
+ * library/msgcat/msgcat.tcl:
+ * library/msgcat/pkgIndex.tcl:
+ * tests/msgcat.test: Revised locale initialization to interpret
+ environment variable locale values according to XPG4, and to recognize
+ the LC_ALL and LC_MESSAGES values over that of LANG. Also added many
+ Windows Registry locale values to those recognized by msgcat. Revised
+ tests and docs. Bumped to version 1.3. Thanks to Bruno Haible for the
+ report and assistance crafting the solution. [Bug 525522, 525525]
+
+2002-06-16 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclCompile.c (TclCompileTokens): a better algorithm for the
+ previous bug fix.
+
+2002-06-16 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclCompile.c (TclCompileTokens):
+ * tests/compile.test: [Bug 569438] in the processing of dollar
+ variables; report by Georgios Petasis.
+
+2002-06-16 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c: bug in the consolidation of the INCR_..._STK
+ instructions; the bug could not be exercised as the (faulty)
+ instruction INST_INCR_ARRAY_STK was never compiled-in (related to [Bug
+ 569438]).
+
+2002-06-14 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c (TclExecuteByteCode): runtime peep-hole
+ optimisation of variables (INST_STORE, INST_INCR) and commands
+ (INST_INVOKE); faster check for the existence of a catch.
+ (TclExecuteByteCode): runtime peep-hole optimisation of comparisons.
+ (TclExecuteByteCode): runtime peep-hole optimisation of INST_FOREACH -
+ relies on peculiarities of the code produced by the bytecode compiler.
+
+2002-06-14 David Gravereaux <davygrvy@pobox.com>
+
+ * win/rules.vc: The test for compiler optimizations was in error.
+ Thanks goes to Roy Terry <royterry@earthlink.net> for his assistance
+ with this.
+
+2002-06-14 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * doc/trace.n, tests/trace.test:
+ * generic/tclCmdMZ.c (Tcl_TraceObjCmd,TclTraceCommandObjCmd)
+ (TclTraceVariableObjCmd): Changed references to "trace list" to
+ "trace info" as mandated by TIP#102.
+
+2002-06-13 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c (TclExecuteByteCode): consolidated code for the
+ conditional branch instructions.
+
+2002-06-13 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c (TclExecuteByteCode): fixed the previous patch;
+ wouldn't compile with TCL_COMPILE_DEBUG set.
+
+2002-06-13 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c (TclExecuteByteCode): consolidated the handling
+ of exception returns to INST_INVOKE and INST_EVAL, as well as most of
+ the code for INST_CONTINUE and INST_BREAK, in the new jump target
+ "processExceptionReturn".
+
+2002-06-13 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c (TclExecuteByteCode): consolidated variable
+ handling opcodes, replaced redundant code with some 'goto'. All
+ store/append/lappend opcodes on the same data type now share the main
+ code; same with incr opcodes.
+ * generic/tclVar.c: added the bit TCL_TRACE_READS to the possible
+ flags to Tcl_SetVar2Ex - it causes read traces to be fired prior to
+ setting the variable. This is used in the core for [lappend].
+
+ ***NOTE*** the usage of TCL_TRACE_READS in Tcl_(Obj)?GetVar.* is not
+ documented; there, it causes the call to create the variable if it
+ does not exist. The new usage in Tcl_(Obj)?SetVar.* remains
+ undocumented too ...

+ * generic/tclIOUtil.c:
+ * doc/FileSystem.3:
+ * mac/tclMacFile.c:
+ * unix/tclUnixFile.c:
+ * win/tclWinFile.c: fixed up further so both compiles and actually
+ works with VC++ 5 or 6.
+ * win/tclWinInt.h:
+ * win/tclWin32Dll.c: cleaned up code and vfs tests and added tests for
+ the internal changes of 2002-06-12, to see whether WinTcl on NTFS can
+ coexist peacefully with links in the filesystem. Added new test
+ command 'testfilelink' to enable the newer code to be tested.
+ * tests/fCmd.test: (made certain tests of 'testfilelink' not run on
+ unix).
+
+2002-06-12 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * tclBasic.c (Tcl_DeleteTrace): fixed [Bug 568123] (thanks to Hemang
+ Lavana)
+
+2002-06-12 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * win/tclWinFile.c: corrected the symbolic link handling code to allow
+ it to compile. Added real definition of REPARSE_DATA_BUFFER (found in
+ winnt.h). Most of the added definitions appear to have correct,
+ cross-Win-version equivalents in winnt.h and should be removed, but
+ just making things "work" for now.
+
+2002-06-12 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclIOUtil.c:
+ * generic/tcl.decls:
+ * generic/tclDecls.h: made code for Tcl_FSNewNativePath agree with man
+ pages.
+
+ * doc/FileSystem.3: clarified the circumstances under which certain
+ functions are called in the presence of symlinks.
+
+ * win/tclWinFile.c:
+ * win/tclWinPort.h:
+ * win/tclWinInt.h:
+ * win/tclWinFCmd.c: Fix for Windows to allow 'file lstat', 'file
+ type', 'glob -type l', 'file copy', 'file delete', 'file normalize',
+ and all VFS code to work correctly in the presence of symlinks
+ (previously Tcl's behaviour was not very well defined). This also
+ fixes possible serious problems in all versions of WinTcl where 'file
+ delete' on a NTFS symlink could delete the original, not the symlink.
+ Note: symlinks cannot yet be created in pure Tcl.
+
+2002-06-11 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclBasic.c:
+ * generic/tclCompCmds.c:
+ * generic/tclInt.h: reverted the new compilation functions; replaced
+ by a more general approach described below.
+
+ * generic/tclCompCmds.c:
+ * generic/tclCompile.c: made *all* compiled variable access attempts
+ create an indexed variable - even get or incr without previous set.
+ This allows indexed access to local variables that are created and set
+ at runtime, for example by [global], [upvar], [variable], [regexp],
+ [regsub].
+
+2002-06-11 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * doc/global.n:
+ * doc/info.n:
+ * test/info.test:
+ * generic/tclCmdIL.c: fix for [Bug 567386], [info locals] was
+ reporting some linked variables.
+
+ * generic/tclBasic.c:
+ * generic/tclCompCmds.c:
+ * generic/tclInt.h: added compile functions for [global], [variable]
+ and [upvar]. They just declare the new local variables, the commands
+ themselves are not compiled-in. This gives a notably faster read
+ access to these linked variables.
+
+2002-06-11 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c: optimised algorithm for exception range
+ lookup; part of [Patch 453709].
+
+2002-06-10 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * unix/tclUnixFCmd.c: fixed [Bug 566669]
+ * generic/tclIOUtil.c: improved and sped up handling of native paths
+ (duplication and conversion to normalized paths), particularly on
+ Windows.
+ * modified part of above commit, due to problems on Linux. Will
+ re-examine bug report and evaluate more closely.
+
+2002-06-07 Don Porter <dgp@users.sourceforge.net>
+
+ * tests/tcltest.test: More corrections to test suite so that tests of
+ failing [test]s don't show up themselves as failing tests.
+
+2002-06-07 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/tclExecute.c: Tidied up headers in relation to float.h to
+ cut the cruft and ensure DBL_MAX is defined since doubles seem to be
+ the same size everywhere; if the assumption isn't true, the variant
+ platforms had better have run configure...
+
+ * unix/tclUnixPort.h (EOVERFLOW): Added code to define it if it
+ wasn't previously defined. Also some other general tidying and adding
+ of comments. [Bugs 563122, 564595]
+ * compat/tclErrno.h: Added definition for EOVERFLOW copied from
+ Solaris headers; I've been unable to find any uses of EFTYPE, which
+ was the error code previously occupying the slot, in Tcl, or any
+ definition of it in the Solaris headers.
+
+2002-06-06 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/dltest/Makefile.in: Remove hard coded CFLAGS=-g and add
+ CFLAGS_DEBUG, CFLAGS_OPTIMIZE, and CFLAGS_DEFAULT varaibles. [Bug
+ 565488]
+
+2002-06-06 Don Porter <dgp@users.sourceforge.net>
+
+ * tests/tcltest.test: Corrections to test suite so that tests of
+ failing [test]s don't show up themselves as failing tests.
+
+ * tests/io.test: Fixed up namespace variable resolution issues
+ revealed by running test suite with "-singleproc 1".
+
+ * doc/tcltest.n:
+ * library/tcltest/tcltest.tcl:
+ * tests/tcltest.test: Several updates to tcltest.
+ 1) changed to lazy initialization of test constraints
+ 2) deprecated [initConstraintsHook]
+ 3) repaired badly broken [limitConstraints].
+ 4) deprecated [threadReap] and [mainThread]

+ LD_LIBRARY_PATH for MacOSX dynamic linker.
+ * generic/tclEnv.c (TclSetEnv): fix env var setting on MacOSX (adapted
+ from [Patch 524352] by jkbonfield).
+
+2002-06-05 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/Tcl_Main.3: Documented $tcl_rcFileName and added more

+2002-05-30 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclCompExpr.c:
+ * generic/tclCompile.c:

+
+2002-05-30 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclFileName.c (TclGlob): fix to longstanding 'knownBug' in
+ fileName tests 15.2-15.4, and fix to a new Tcl 8.4 bug in certain uses
+ of 'glob -tails'.
+ * tests/fileName.test: removed 'knownBug' flag from some tests, added

+
+2002-05-29 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * unix/configure: regen'ed
+ * unix/configure.in: replaced bigendian check with autoconf standard
+ AC_C_BIG_ENDIAN, which defined WORDS_BIGENDIAN on bigendian systems.
+ * generic/tclUtf.c (Tcl_UniCharNcmp):
+ * generic/tclInt.h (TclUniCharNcmp): use WORDS_BIGENDIAN instead of
+ TCL_OPTIMIZE_UNICODE_COMPARE to enable memcmp alternative.
+
+ * generic/tclExecute.c (TclExecuteByteCode INST_STR_CMP):
+ * generic/tclCmdMZ.c (Tcl_StringObjCmd): changed the case for choosing
+ the Tcl_UniCharNcmp compare to when both objs are of StringType, as
+ benchmarks show that is the optimal check (both bigendian and
+ littleendian systems).
+
+2002-05-29 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclMain.c: Removed "dummy" reference to Tcl_LinkVar. It is
+ no longer needed since Tcl_Main() now actually calls Tcl_LinkVar().
+ Thanks to Joe English for pointing that out.
+
+2002-05-29 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/tclExecute.c (TclExecuteByteCode):
+ * generic/tclCmdMZ.c (Tcl_StringObjCmd): Use the macro version.
+ * generic/tclInt.h (TclUniCharNcmp): Optimised still further with a
+ macro for use in sensitive places like tclExecute.c
+
+ * generic/tclUtf.c (Tcl_UniCharNcmp): Use new flag to figure out when
+ we can use an optimal comparison scheme, and default to the old scheme
+ in other cases which is at least safe.
+ * unix/configure.in (TCL_OPTIMIZE_UNICODE_COMPARE): New optional flag
+ that indicates when we can use memcmp() to compare Unicode strings
+ (i.e. when the high-byte of a Tcl_UniChar precedes the low-byte.)
+
+2002-05-29 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tclInt.decls:
+ * generic/tclIntDecls.h:
+ * generic/tclStubInit.c:
+ * generic/tclUtf.c: added TclpUtfNcmp2 private command that
+ mirrors Tcl_UtfNcmp, but takes n in bytes, not utf-8 chars. This
+ provides a faster alternative for comparing utf strings internally.
+ (Tcl_UniCharNcmp, Tcl_UniCharNcasecmp): removed the explicit end of
+ string check as it wasn't correct for the function (by doc and logic).
+
+ * generic/tclCmdMZ.c (Tcl_StringObjCmd): reworked the string equal
+ comparison code to use TclpUtfNcmp2 as well as short-circuit for
+ equal objects or unequal length strings in the equal case.
+ Removed the use of goto and streamlined the other parts.
+
+ * generic/tclExecute.c (TclExecuteByteCode): added check for object
+ equality in the comparison instructions. Added short-circuit for !=
+ length strings in INST_EQ, INST_NEQ and INST_STR_CMP. Reworked
+ INST_STR_CMP to use TclpUtfNcmp2 where appropriate, and only use
+ Tcl_UniCharNcmp when at least one of the objects is a Unicode obj with
+ no utf bytes.
+
+ * generic/tclCompCmds.c (TclCompileStringCmd): removed error creation
+ in code that no longer throws an error.
+
+ * tests/string.test:
+ * tests/stringComp.test: added more string comparison checks.
+
+ * tests/clock.test: better qualified 9.1 constraint check for %s.
+
+2002-05-28 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tclThreadAlloc.c (TclpRealloc, TclpFree): protect
+ against the case when NULL is based.
+
+ * tests/clock.test: added clock-9.1
+ * compat/strftime.c:
+ * generic/tclClock.c:
+ * generic/tclInt.decls:
+ * generic/tclIntDecls.h:
+ * unix/tclUnixTime.c: fix for Windows msvcrt mem leak caused by using
+ an env(TZ) setting trick for in clock format -gmt 1. This also makes
+ %s seem to work correctly with -gmt 1 as well as making it a lot
+ faster by avoid the env(TZ) hack. TclpStrftime now takes useGMT as an
+ arg. [Bug 559376]
+
+2002-05-28 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclIOUtil.c: fixes to Tcl_FSLoadFile when called on a file
+ inside a vfs. This should avoid leaving temporary files sitting
+ around on exit. [Bug 545579]
+
+2002-05-27 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * win/tclWinError.c: Added comment on conversion of
+ ERROR_NEGATIVE_SEEK because that is a mapping that really belongs,
+ and not a catch-all case.
+ * win/tclWinPort.h (EOVERFLOW): Should be either EFBIG or EINVAL
+ * generic/tclPosixStr.c (Tcl_ErrnoId, Tcl_ErrnoMsg): EOVERFLOW can
+ potentially be a synonym for EINVAL.
+
+2002-05-24 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ === Changes due to TIP#91 ===
+
+ * win/tclWinPort.h: Added declaration of EOVERFLOW.
+ * doc/CrtChannel.3: Added documentation of wideSeekProc.
+ * generic/tclIOGT.c (TransformSeekProc, TransformWideSeekProc):
+ Adapted to use the new channel mechanism.
+ * unix/tclUnixChan.c (FileSeekProc, FileWideSeekProc): Renamed
+ FileSeekProc to FileWideSeekProc and created new FileSeekProc which
+ has the old-style interface and which errors out with EOVERFLOW when
+ the returned file position can't fit into the return type (int for
+ historical reasons).
+ * win/tclWinChan.c (FileSeekProc, FileWideSeekProc): Renamed
+ FileSeekProc to FileWideSeekProc and created new FileSeekProc which
+ has the old-style interface and which errors out with EOVERFLOW when
+ the returned file position can't fit into the return type (int for
+ historical reasons).
+ * mac/tclMacChan.c (FileSeek): Reverted to old interface; Macs lack
+ large-file support because I can't see how to add it.
+ * generic/tclIO.c (Tcl_Seek, Tcl_Tell): Given these functions
+ knowledge of the new arrangement of channel types.
+ (Tcl_ChannelVersion): Added recognition of new version code.
+ (HaveVersion): New function to do version checking.
+ (Tcl_ChannelBlockModeProc, Tcl_ChannelFlushProc)
+ (Tcl_ChannelHandlerProc): Made these functions use HaveVersion for
+ ease of future maintainability.
+ (Tcl_ChannelBlockModeProc): Obvious lookup function.
+ * generic/tcl.h (Tcl_ChannelType): New wideSeekProc field, and
+ seekProc type restored to old interpretation.
+ (TCL_CHANNEL_VERSION_3): New channel version.
+
+2002-05-24 Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+ * tests/winPipe.test: Applied patch for [Bug 549617]. Patch and bug
+ report by Kevin Kenny <kennykb@users.sourceforge.net>.
+
+ * win/tclWinSock.c (TcpWatchProc): Fixed [Bug 557878]. We are not
+ allowed to mess with the watch mask if the socket is a server socket.
+ I believe that the original reporter is George Peter Staplin.
+
+2002-05-21 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/configure: Regen.
+ * unix/configure.in: Invoke SC_ENABLE_SHARED before calling
+ SC_CONFIG_CFLAGS so that the SHARED_BUILD variable can be checked
+ inside SC_CONFIG_CFLAGS.
+ * unix/tcl.m4 (SC_CONFIG_CFLAGS): Pass -non_shared instead of -shared
+ to ld when configured with --disable-shared under OSF. [Bug 540390]
+
+2002-05-20 Daniel Steffen <das@users.sourceforge.net>
+
+ * generic/tclInt.h: added prototype for TclpFilesystemPathType().
+ * mac/tclMacChan.c: use MSL provided creator type if available instead
+ of the default 'MPW '.
+
+2002-05-16 Joe English <jenglish@users.sf.net>
+
+ * doc/CrtObjCmd.3: Added Tcl_GetCommandFromObj, Tcl_GetCommandFullName
+ [Bugs 547987, 414921]
+
+2002-05-14 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * unix/tclUnixChan.c (TtyOutputProc): #if/#endif-ed this function out
+ to stop compiler warnings. Also much general tidying of comments in
+ this file and removal of whitespace from blank lines.
+
+2002-05-13 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * unix/tclUnixChan.c (SETBREAK): Solaris thinks ioctl() takes a signed
+ second argument, and Linux thinks ioctl() takes an unsigned second
+ argument. So need a longer definition of this macro to get neither to
+ spew warnings...
+
+2002-05-13 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclEvent.c:
+ * generic/tclIOUtil.c:
+ * generic/tclInt.h: clean up all memory allocated by the filesystem,
+ via introduction of 'TclFinalizeFilesystem'.
+ Move TclFinalizeLoad into TclFinalizeFilesystem so we can be sure it
+ is called at just the right time.
+ Fix bad comment also. [Bug 555078 and 'fs' part of 543549]
+ * win/tclWinChan.c: fix comment referring to wrong function.
+
+2002-05-10 Don Porter <dgp@users.sourceforge.net>
+
+ * tests/load.test:
+ * tests/safe.test:
+ * tests/tcltest.test: Corrected some list-quoting issues and other
+ matters that cause tests to fail when the patch includes special
+ characters. Report from Vince Darley. [Bug 554068]
+
+2002-05-08 David Gravereaux <davygrvy@pobox.com>
+
+ * doc/file.n:
+ * tools/man2tcl.c:
+ * tools/man2help2.tcl: Thanks to Peter Spjuth
+ <peter.spjuth@space.se>, again. My prior fix for single-quote macro
+ mis-understanding was wrong. Reverted to reimpliment the 'macro2' proc
+ which handles single-quote macros and restored file.n text arrangement
+ to avoid single-quotes on the first line. Sorry for all the confusion.
+
+2002-05-08 David Gravereaux <davygrvy@pobox.com>
+
+ * tools/man2tcl.c:
+ * tools/man2help2.tcl: Proper source of macro error misunderstanding
+ single-quote as the leading macro command found and repaired.
+
+ * doc/file.n: Reverted to prior state before I messed with it.
+
+2002-05-08 Don Porter <dgp@users.sourceforge.net>
+
+ * library/tcltest/tcltest.tcl: Corrected [uplevel] quoting when
+ [source]-ing test script in subdirectories.
+ * tests/fileName.test:
+ * tests/load.test:
+ * tests/main.test:
+ * tests/tcltest.test:
+ * tests/unixInit.test: Fixes to test suite when there's a space in the
+ working path. Thanks to Kevin Kenny.
+
+2002-05-07 David Gravereaux <davygrvy@pobox.com>
+
+ -- Changes from Peter Spjuth <peter.spjuth@space.se>
+ * tools/man2tcl.c: Increased line buffer size and a bail-out if that
+ should ever be over-run.
+ * tools/man2help.tcl: Include Courier New font in rtf header.
+ * tools/man2help2.tcl: Improved handling of CS/CE fields. Use Courier
+ New for code samples and indent better.
+
+ * doc/file.n:
+ * doc/TraceCmd.3: winhelp conversion tools where understanding
+ a ' as the first character on a line to be an unknown macro.
+ Not knowing how to repair tools/man2tcl.c, I decided to rearrange
+ the text in the docs instead.
+
+2002-05-07 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclFileName.c: fix to similar segfault when using 'glob
+ -types nonsense -dir dirname -join * *'. [Bug 553320]
+
+ * doc/FileSystem.3: further documentation on vfs.
+ * tests/cmdAH.test:
+ * tests/fileSystem.test:
+ * tests/pkgMkindex.test: Fix to testsuite bugs when running out of
+ directory whose name contains '{' or '['.
+
+2002-05-07 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * tests/basic.test: Fix for [Bug 549607]
+ * tests/encoding.test: Fix for [Bug 549610]
+ These are testsuite bugs that caused failures when the filename
+ contained spaces. Report & fix by Kevin Kenny.
+
+2002-05-02 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclFileName.c: fix to freeing a bad object (i.e. segfault)
+ when using 'glob -types nonsense -dir dirname'.
+ * generic/tclWinFile.c: fix to [Bug 551306], also wrapped some long
+ lines.
+ * tests/fileName.test: added several tests for the above bugs.
+ * doc/FileSystem.3: clarified documentation on refCount requirements
+ of the object returned by the path type function.
+ * generic/tclIOUtil.c:
+ * win/tclWinFile.c:
+ * unix/tclUnixFile.c:
+ * mac/tclMacFile.c: moved TclpFilesystemPathType to the platform-
+ specific directories, so we can add missing platform-specific
+ implementations. On Windows, 'file system' now returns useful results
+ like "native NTFS", "native FAT" for that system. Unix and MacOS still
+ only return "native".
+ * doc/file.n: clarified documentation.
+ * tests/winFile.test: test for 'file system' returning correct values.
+ * tests/fileSystem.test: test for 'file system' returning correct
+ values. Clean up after failed previous test run.
+
+2002-04-26 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * unix/configure:
+ * unix/tcl.m4: change HP-11 SHLIB_LD_LIBS from "" to ${LIBS} so that
+ the .sl knows its dependent libs.
+
+2002-04-26 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * tests/obj.test (obj-11.[56]): Test conversion to boolean more
+ thoroughly.
+ * generic/tclObj.c (SetBooleanFromAny): Was not calling an integer
+ parsing function on native 64-bit platforms! [Bug 548686]
+
+2002-04-24 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tclInt.h: corrected TclRememberJoinableThread decl to use
+ VOID instead of void.
+ * generic/tclThreadJoin.c: noted that this code isn't needed on Unix.
+
+2002-04-23 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * doc/exec.n:
+ * doc/tclvars.n: doc updates [Patch 509426] (gravereaux)
+
+2002-04-24 Daniel Steffen <das@users.sourceforge.net>
+
+ * mac/tclMacResource.r: added check of TCLTK_NO_LIBRARY_TEXT_RESOURCES
+ #define to allow disabling the inclusion of the tcl library code in
+ the resource fork of Tcl executables and shared libraries.
+
+2002-04-23 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * doc/TraceCmd.3: New file that documents Tcl_CommandTraceInfo,
+ Tcl_TraceCommand and Tcl_UntraceCommand [Bug 414927]
+
+2002-04-22 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tclAlloc.c:
+ * generic/tclInt.h:
+ * generic/tclThreadAlloc.c (new):
+ * unix/Makefile.in:
+ * unix/tclUnixThrd.c:
+ * win/Makefile.in:
+ * win/tclWinInt.h:
+ * win/tclWinThrd.c: added new threaded allocator contributed by AOL
+ that significantly reduces lock contention when multiple threads are
+ in use. Only Windows and Unix implementations are ready, and the
+ Windows one may need work. It is only used by default on Unix for now,
+ and requires that USE_THREAD_ALLOC be defined (--enable-threads on
+ Unix will define this).
+
+ * generic/tclIOUtil.c (Tcl_FSRegister, Tcl_FSUnregister): corrected
+ calling of Tcl_ConditionWait to ensure that there would be a condition
+ to wait upon.
+
+ * generic/tclCmdAH.c (Tcl_FileObjCmd): added cast in FILE_SIZE.
+
+ * win/tclWinFCmd.c (DoDeleteFile): check return of setattr API calls
+ in file deletion for correct Win32 API handling.
+
+ * win/Makefile.in: correct dependencies for shell, gdb, runtest
+ targets.
+
+ * doc/clock.n:
+ * compat/strftime.c (_fmt): change strftime to correctly handle
+ localized %c, %x and %X on Windows. Added some notes about how the
+ other values could be further localized.
+
+2002-04-19 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclMain.c (Tcl_Main): Free the memory allocated for the
+ startup script path. [Bug 543549]
+
+ * library/msgcat/msgcat.tcl: [mcmax] wasn't using the caller's
+ namespace when determining the max translated length. Also made
+ revisions for better use of namespace variables and more efficient
+ [uplevel]s.
+
+ * doc/msgcat.n:
+ * library/msgcat/msgcat.tcl:
+ * library/msgcat/pkgIndex.tcl: Added [mcload] to the export list of
+ msgcat; bumped to 1.2.3. [Bug 544727]
+
+2002-04-20 Daniel Steffen <das@users.sourceforge.net>
+
+ * generic/tclInt.decls:
+ * generic/tclIntPlatDecls.h:
+ * generic/tclStubInit.c:
+ * mac/tclMacFCmd.c:
+ * mac/tclMacFile.c:
+ * mac/tclMacUtil.c: Modified TclpObjNormalizePath to be alias file
+ aware, and replaced various calls to FSpLocationFrom*Path by calls to
+ new alias file aware versions FSpLLocationFrom*Path. The alias file
+ aware routines don't resolve the last component of a path if it is an
+ alias. This allows [file copy/delete] etc. to act correctly on alias
+ files. (c.f. discussion in [Bug 511666])
+
+2002-04-19 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * tests/lindex.test (lindex-3.7):
+ * generic/tclUtil.c (TclGetIntForIndex): Stopped indexes from hitting

+
+2002-04-18 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclNamesp.c:
+ * tests/info.test: [Bug 545325] info level didn't report namespace
+ eval, bug report by Richard Suchenwirth.
+
+2002-04-18 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/subst.n: Clarified documentation on handling unusual return
+ codes during substitution, and on variable substitutions implied by
+ command substitution, and vice versa. [Bug 536838]
+
+2002-04-18 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/tclCmdIL.c (InfoBodyCmd):
+ * tests/info.test (info-2.6): Proc bodies without string reps would
+ report as empty. [Bug 545644]
+
+ * generic/tclCmdMZ.c (Tcl_SubstObj): More clarification for comment on
+ behaviour when substitutions are not well-formed, prompted by [Bug
+ 536831]; alas, removing the ill-defined behaviour is a lot of work.
+
+2002-04-18 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclExecute.c:
+ * tests/expr-old.test: fix for [Bug 542588] (Phil Ehrens), where "too
+ large integers" were reported as "floating-point value" in [expr]
+ error messages.
+
+2002-04-17 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tclEncoding.c (EscapeFromUtfProc):
+ * generic/tclIO.c (WriteChars, Tcl_Close): corrected the handling of
+ outputting end escapes for escape-based encodings.
+ [Bug 526524] (yamamoto)
+
+2002-04-17 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/tcltest.n: Removed [saveState] and [restoreState] from tcltest
+ 2 documentation, effectively deprecating them. [Bug 495660]
+ * library/tcltest/tcltest.tcl: Made separate export for commands kept
+ only for tcltest 1 compatibility.
+
+ * tests/iogt.test: Revised to run tests in a namespace, rather than
+ use the useless and buggy [saveState] and [restoreState] commands of
+ tcltest. Updated to use tcltest 2 as well. [Patch 544911]
+
+2002-04-16 Don Porter <dgp@users.sourceforge.net>

+
+2002-04-15 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclProc.c:
+ * tests/proc-old.test: Improved stack trace for TCL_BREAK and
+ TCL_CONTINUE returns from procs. Patch by Don Porter [Bug 536955].
+
+ * generic/tclExecute.c:
+ * tests/compile.test: made bytecodes check for a catch before
+ returning; the compiled [return] is otherwise non-catchable. [Bug
+ 542142] reported by Andreas Kupries.
+
+2002-04-15 Don Porter <dgp@users.sourceforge.net>

+
+ * doc/tcltest.n:
+ * library/tcltest/tcltest.tcl:
+ * tests/tcltest.test: Revised [tcltest::test] to return errors when

+
+2002-04-08 Daniel Steffen <das@users.sourceforge.net>
+

+ * mac/tclMacSock.c (TcpGetOptionProc): fixed bug introduced by Andreas
+ on 02-25; changed strcmp's to strncmp's so that option comparison

+ * tests/basic.test:
+ * tests/cmdAH.test:
+ * tests/encoding.test:

+
+2002-04-06 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * unix/tclUnixFCmd.c (Realpath): added a little extra code to

+ prevent spurious purify warnings. We should really create our own
+ realpath implementation, but this will at least quiet purify for now.
+
+2002-04-05 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclCmdMZ.c (Tcl_SubstObj):
+ * tests/subst.test: Corrected [subst] so that return codes TCL_BREAK

+ effect as when those codes are returned by command substitution. [Bug
+ 536879]
+
+2002-04-03 Jeff Hobbs <jeffh@ActiveState.com>

+
+2002-04-01 Kevin Kenny <kennykb@acm.org>
+
+ * win/tclWinTime.c (Tcl_GetTime): made the checks of clock frequency

+ frequency.
+
+2002-03-29 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tclCmdMZ.c (Tcl_TraceObjCmd, TraceVarProc)
+ (TraceCommandProc, TclTraceCommandObjCmd): corrected potential
+ double-free of traces on variables by flagging in Trace*Proc that it
+ will free the var in case the eval wants to delete the var trace as
+ well. [Bug 536937] Also converted Tcl_UntraceVar -> Tcl_UntraceVar2

+ the tools/ directory. This does not address the syntax errors in the
+ man files. Having the contents of tcl.hpj(.in) inside makefile.vc
+ allows for version numbers to be replaced with macros.
+
+ The new nmakehlp.c is built by rules.vc in preprocessing and removes
+ the need to use tricky shell syntax that wasn't compatible on Win9x
+ systems. Clean targets made Win9x complient. This is a first draft
+ repair for [Bug 533862].
+
+2002-03-28 Miguel Sofer <msofer@users.sourceforge.net>

+
+ * library/tcltest/tcltest.tcl: Keep the value of $::auto_path

+ Improve the processing of the -constraints option to [test] so that

+ 'Tcl_FSMatchInDirectory' which now might match a single file/directory
+ only, and 'file normalize' which wasn't very clear before. Removed
+ inconsistency betweens docs and the Tcl_Filesystem structure. Also
+ fixed [Bug 523217] and corrected file normalization on Unix so that
+ it expands symbolic links. Added some new tests of the filesystem
+ code (in the new file 'fileSystem.test'), and some extra tests for
+ correct handling of symbolic links. Fix to [Bug 530960] which shows up
+ on Win98. Made comparison with ".com" case insensitive in tclWinPipe.c
+
+ ***POTENTIAL INCOMPATIBILITY***: But only between alpha releases
+ (users of the new Tcl_Filesystem lookup table in Tcl 8.4a4 need to
+ handle the new way in which Tcl may call Tcl_FSMatchInDirectory, and
+ 'file normalize' on unix now behaves correctly). Only known impact is
+ with the 'tclvfs' extension.

+ is the controlling terminal and is special. Setting it into raw mode
+ as is done for other tty's is a bad idea. This is a hackish fix for

+ * compat/strtod.c (strtod): simplified #includes
+ * compat/strtol.c (strtol): gather result in a long before returning
+ as a long: necessary on platforms where sizeof(int) != sizeof(long).
+
+2002-02-25 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/tclLoadDyld.c: updated to use Mac OS X 10.1 dyld APIs that

+
+2002-02-25 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclCompCmds: fixing a bug in patch dated 2002-02-22, in the
+ code for [for] and [while]. Under certain conditions, for long bodies,
+ the exception range parameters were badly computed. Tests forthcoming:
+ I still can't reproduce the conditions in the testsuite (!), although
+ the bug (with assorted segfault or panic!) can be triggered from the
+ console or with the new parse.bench in tclbench.
+
+2002-02-25 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * compat/strtoul.c, compat/strtol.c, compat/strtod.c: Added UCHAR,

+
+ * compat/strtoull.c (strtoull):
+ * compat/strtoll.c (strtoll):
+ * compat/strtoul.c (strtoul): Fixed failure to handle leading
+ sign symbols '+' and '-' and '0X' and raise overflow errors.
+ [Bug 440916] Also corrects prototype and errno problems.
+
+2002-02-23 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * configure: Regen.
+ * unix/tcl.m4 (SC_CONFIG_CFLAGS): Link with -n32 instead of -32 when

+
+2002-02-22 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclInt.h:
+ * generic/tclObj.c: renamed global variable emptyString ->

+ platform without backlinking without proper use of stubs. [Bug 476537]
+
+2002-02-22 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * tests/regexpComp.test: updated regexp-11.[1-4] to match changes in
+ regexp.test for new regsub syntax
+
+ * unix/configure:
+ * unix/tcl.m4: added --enable-64bit support for AIX-4 (using -q64
+ flag) when using IBM's xlc compiler.
+
+ * tests/safe.test: updated safe-8.5 and safe-8.7
+ * library/safe.tcl (CheckFileName): removed the limit on
+ sourceable file names (was only *.tcl or tclIndex files with no more
+ than one dot and 14 chars). There is enough internal protection in a
+ safe interpreter already. [Tk Bug 521560]
+
+2002-02-22 Miguel Sofer <msofer@users.sourceforge.net>
+
+ * generic/tclCompCmds: [FR 465811]. Optimising [if], [for] and [while]
+ for constant conditions; in addition, [for] and [while] are now
+ compiled with the "loop rotation" optimisation (thanks to Kevin
+ Kenny).
+

+
+ --- TIP#76 CHANGES ---
+ * generic/tclCmdMZ.c (Tcl_RegsubObjCmd): Final-argument-less
+ [regsub] returns the modified string.
+ * doc/regsub.n: Updated docs.
+ * tests/regexp.test: Updated and added tests.
+
+ * compat/strtoll.c (strtoll):
+ * compat/strtoull.c (strtoull):
+ * unix/tclUnixPort.h:
+ * win/tclWinPort.h: Const-ing 64-bit compatability declarations. Note
+ that the return pointer is non-const because it is entirely legal for
+ the functions to be called from somewhere that owns the string being
+ passed. Fixes problem reported by Larry Virden.
+
+2002-02-21 David Gravereaux <davygrvy@pobox.com>
+
+ * win/mkd.bat (removed):
+ * win/coffbase.txt (new):
+ * win/makefile.bc:
+ * win/makefile.vc: Changed the 'setup' target to stop using the
+ mkd.bat file and just make the directory right in the rule. Same
+ change to makefile.bc. Neither configure.in nor Makefile.in use it.
+
+ coffbase.txt will be the master list for our "prefered base addresses"
+ set by the linker. This should improve load-time (NT only) by avoiding
+ relocations. Submissions to the list by extension authors are
+ encouraged.
+
+ Added a 'tidy' target to compliment 'clean' and 'hose' to remove just
+ the outputs. Also removed the $(winlibs) macro as it wasn't being
+ used.
+
+ Stuff left to do:
+ 1) get the winhelp target to stop building in the tools/ directory.
+ 2) stop using rmd.bat
+ 3) add more dependacy rules.
+
+ * win/tclAppInit.c: Reverted back to -r1.6, as the header file change
+ to tclPort.h won't allow for easy embedded support outside of the
+ source dist. Thanks to Don Porter for pointing this out to me.
+
+2002-02-21 David Gravereaux <davygrvy@pobox.com>
+
+ * win/makefile.vc:
+ * win/rules.vc: Added a new "loimpact" option that sets the
+ -ws:aggressive linker option. Off by default. It's said to keep the
+ heap use low at the expense of alloc speed.
+
+ * win/tclAppInit.c: Changed #include "tcl.h" to be tclPort.h to remove
+ the raw windows.h include. tclPort.h brings in windows.h already and
+ lessens the pre-compiled-header mush and the randomly useless #pragma
+ comment (lib,...) references throughout the big windows.h tree (as
+ observed at high linker warning levels).
+
+2002-02-21 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/tcl.h: Better guessing of LP64/ILP32 architecture, but now
+ sensitive to presence of (suitable) <limits.h>
+
+2002-02-20 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tcl.decls (Tcl_RegExpRange,Tcl_GetIndexFromObjStruct):
+ Overlooked a few source incompatibilities. Now using CONST84.
+ * generic/tclDecls.h: make genstubs
+ * generic/tcl.h (Tcl_CmdObjTraceProc): silence warning from Sun
+ Workshop compiler.
+
+2002-02-20 David Gravereaux <davygrvy@pobox.com>
+
+ * win/buildall.vc.bat:
+ * win/makefile.vc:
+ * win/rules.vc: General clean-ups. Added compiler and linker tests for
+ a) the pentium 0x0F errata, b) optimizing (not all have this), and c)
+ linker v6 section alignment confusion. All these are tested first to
+ make sure any D4002 or LNK1117 warnings aren't displayed. The pentium
+ 0x0F errata is a recommended switch. The v5 linker's section alignment
+ default is 512, but the v6 linker was changed to 4096 in an attempt to
+ speed loading on Win98. I changed the default to always be 512 across
+ both linkers, unless linking statically, then 4096 is used for the
+ claimed speed effect. Using a 512 alignment saves 12k bytes of dead
+ space in the DLL.
+
+ Added IA64 B-stepping errata switch when the compiler supports it.
+
+ Added profiling to $(lflags) when requested and also removed the
+ explict -entry option as the default works fine as is.
+
+ Removed win/tclWinInit.c from the special case section to let it use
+ the common implicit rule as the $(EXTFLAGS) macro it had was never
+ referenced anywhere.
+
+2002-02-20 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/tcl.h: Added code to guess the correct settings for
+ TCL_WIDE_INT_IS_LONG and TCL_WIDE_INT_TYPE when configure doesn't tell
+ us them, as can happen with extensions.
+
+2002-02-19 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * doc/format.n: Updated docs to list the specification.
+ * generic/tclCmdAH.c (Tcl_FormatObjCmd): Made behaviour on 64-bit
+ platforms correctly meet the specification, that %d works with the
+ native word-sized integer, instead of trying to guess (wrongly)
+ from the value being passed.
+
+2002-02-19 Don Porter <dgp@users.sourceforge.net>
+
+ * changes: First draft of updated changes for 8.4a4 release.
+
+2002-02-15 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * unix/tclUnixPort.h: add strtoll/strtoull declarations for
+ platforms that do not define them.
+
+ * generic/tclIndexObj.c (STRING_AT): removed ptrdiff_t cast and
+ use of VOID* in default case (GNU-ism).

+
+ +----------------------+
+ | TIP #72 IMPLEMENTED. |
+ +----------------------+
+
+ There are a lot of changes from this TIP, so please see
+ http://purl.org/tcl/tip/72.html for discussion of
+ backward-compatability issues, but the main ones modifications are in:
+
+ * generic/tcl.h: New types.
+ * generic/tcl.decls: New public functions.
+ * generic/tclExecute.c: 64-bit aware bytecode engine.
+ * generic/tclBinary.c: 64-bit handling in [binary] command.
+ * generic/tclScan.c: 64-bit handling in [scan] command.
+ * generic/tclCmdAH.c: 64-bit handling in [file] and [format]
+ commands.
+ * generic/tclBasic.c: New "wordSize" entry in ::tcl_platform.
+ * generic/tclFCmd.c: Large-file support (with many consequences.)
+ * generic/tclIO.c: Large-file support (with many consequences.)
+ * compat/strtoll.c, compat/strtoull.c: New support functions.
+ * unix/tcl.m4, unix/configure: 64-bit support and greatly enhanced
+ cacheing.
+
+ Most other changes, including all those in doc/* and test/* as well as
+ the majority in the platform directories, follow on from these.
+
+ Also coming out of the woodwork:
+ * generic/tclIndex.c: Better support for Cray PVP.
+ * win/tclWinMtherr.c: Better Borland support.
+
+ Note that, in a number of places through the Unix part of the platform
+ support, there are Tcl_Platform* references. These are expanded into
+ the correct way to call that particular underlying function, i.e. with
+ or without a '64' suffix, and should be used by people working on the
+ core in preference to the API functions they overlay so that the code
+ remains portable depending on the presence or absence of 64-bit
+ support on the underlying platform.
+
+ ***POTENTIAL INCOMPATIBILITY***: Extracted from the TIP
+
+ SUMMARY OF INCOMPATIBILITIES AND FIXES
+ ======================================
+
+ The behaviour of expressions containing constants that appear positive
+ but which have a negative internal representation will change, as
+ these will now usually be interpreted as wide integers. This is always
+ fixable by replacing the constant with int(constant).
+
+ Extensions creating new channel types will need to be altered as
+ different types are now in use in those areas. The change to the
+ declaration of Tcl_FSStat and Tcl_FSLstat (which are the new preferred
+ API in any case) are less serious as no non-alpha releases have been
+ made yet with those API functions.
+
+ Scripts that are lax about the use of the l modifier in format and
+ scan will probably need to be rewritten. This should be very uncommon
+ though as previously it had absolutely no effect.
+
+ Extensions that create new math functions that take more than one
+ argument will need to be recompiled (the size of Tcl_Value changes),
+ and functions that accept arguments of any type (TCL_EITHER) will need
+ to be rewritten to handle wide integer values. (I do not expect this
+ to affect many extensions at all.)
+
+2002-02-14 Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+ * generic/tclIOCmd.c (Tcl_GetsObjCmd): Trivial fix for [Bug 517503], a
+ memory leak reported by Miguel Sofer <msofer@users.sf.net>. The leak
+ happens if an error occurs for "set var [gets $chan]" and leak one
+ empty object.
+
+2002-02-12 David Gravereaux <davygrvy@pobox.com>
+
+ * djgpp/ (new directory)
+ * djgpp/Makefile (new):
+ * unix/tclAppInit.c:
+ * unix/tclMtherr.c:
+ * unix/tclUnixFCmd.c:
+ * unix/tclUnixFile.c:
+ * unix/tclUnixInit.c:
+ * unix/tclUnixPort.h: Early stage of DJGPP support for building Tcl
+ on DOS. Dynamic loading isn't working, yet. Requires watt32 for the
+ TCP/IP stack. No autoconf, yet. Barely tested, but makes a working exe
+ that runs Tcl in protected-mode, flat memory. [exec] and pipes will
+ need the most work as multi-tasking on DOS has to be carefully.

+
+2002-02-08 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * unix/configure:

+
+ * unix/tclUnixPort.h:

+ return (Tcl_UniChar *). Modified some callers. This change recognizes
+ that Tcl_DStrings are de-facto white-box objects.
+
+ * generic/tclDecls.h:
+ * generic/tclPlatDecls.h: make genstubs
+
+ * generic/tclCmdMZ.c: corrected use of C++-style comment.
+
+2002-02-06 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * tests/scan.test:
+ * generic/tclScan.c (Tcl_ScanObjCmd): corrected scan 0x... %x handling
+ that didn't accept the 0x as a prelude to a base 16 number. [Bug
+ 495213]
+
+ * generic/tclCompCmds.c (TclCompileRegexpCmd): made early check for
+ bad RE to stop checking further.
+
+ * generic/tclCmdMZ.c (Tcl_RegsubObjCmd): added special case to search
+ for simple 'string map' style regsub calls. Delayed creation of
+ resultPtr object until an initial match is made, as the input string
+ object can then be reused for no matches.
+ (Tcl_StringObjCmd): optimization improvements to the STR_MAP
+ algorithm for zero-length and nocase cases.
+
+ * tests/regexp.test:
+ * tests/regexpComp.test: extra code coverage tests.
+
+ * tests/string.test: added 10.18 and 10.19 extra tests.

+
+2002-02-04 Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+ * unix/tclUnixChan.c (FileOutputProc): Fixed [bug 465765] reported by
+ Dale Talcott <daletalcott@users.sourceforge.net>. Avoid writing
+ nothing into a file as STREAM based implementations will consider this
+ a EOF (if the file is a pipe). Not done in the generic layer as this
+ type of writing is actually useful to check the state of a socket.
+
+ * doc/open.n: Fixed [Bug 511540], added cross-reference to 'pid' as
+ the command to use to retrieve the pid of a command pipeline created
+ via 'open'.
+
+2002-02-01 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tclCmdMZ.c (Tcl_RegexpObjCmd): handle quirky about case
+ earlier to avoid shimmering problem.
+
+2002-02-01 Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+ * tests/io.test: io-39.22 split into two tests, one platform

+ platform.
+
+2002-02-01 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclTest.c: fix to picky windows compiler problem with the

+
+2002-01-31 Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+ * win/tclWinFCmd.c: TIP 27: Applied patch fixing CONST warnings on

+
+ * generic/tcl.decls:
+ * generic/tcl.h:
+ * generic/tclInt.h: For each interface identified in the TIP 27
+ changes below as a POTENTIAL INCOMPATIBILITY, the source of the
+ incompatibility has been parameterized so that it can be removed. When
+ compiling extension code against the Tcl header files, use the
+ compiler flag -DUSE_NON_CONST to remove the irresolvable source
+ incompatibilities introduced by the TIP 27 changes. Resolvable changes
+ are left for extension authors to resolve.
+ * generic/tclDecls.h: make genstubs
+
+2002-01-30 Vince Darley <vincentdarley@users.sourceforge.net>

+2002-01-28 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/tcl.m4 (SC_LOAD_TCLCONFIG):
+ * win/tcl.m4 (SC_LOAD_TCLCONFIG): Set TCL_LIB_SPEC, TCL_STUB_LIB_SPEC,
+ and TCL_STUB_LIB_PATH to the values of TCL_BUILD_LIB_SPEC,
+ TCL_BUILD_STUB_LIB_SPEC, and TCL_BUILD_STUB_LIB_PATH when tclConfig.sh
+ is loaded from the build directory. A Tcl extension should make use of
+ the non-build versions of these variables since they will work in both
+ cases. This modification was described in TIP 34.
+
+2002-01-28 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * win/tclWinReg.c (regConnectRegistryProc,RecursiveDeleteKey)
+ (DeleteKey,GetKeyNames,GetType,GetValue,OpenSubKey,SetValue):
+ redid the CONSTification as previous changes caused failing tests.
+
+ * tests/regexpComp.test (new):
+ * generic/tclInt.h:
+ * generic/tclBasic.c: added TclCompileRegexpCmd entry
+ * generic/tclCompCmds.c (TclCompileStringCmd): corrected to return
+ TCL_OUT_LINE_COMPILE instead of TCL_ERROR for parsing errors, so
+ it only throws the error for runtime compile, in case the user
+ modifies 'string'.
+ (TclCompileRegexpCmd): first try at a byte-compiled regexp command. It
+ handles static strings and ^$ bounded static strings.
+ (TclCompileAppendCmd): made TclPushVarName call always use
+ TCL_CREATE_VAR as numWords is always > 2 at that point.
+
+ * generic/tclExecute.c (TclExecuteByteCode:INST_LIST): correct
+ possibly dangerous decr in macro call.
+
+ * win/tclWinInit.c (TclpFindVariable): CONSTification touch-up
+
+ * win/tclWinReg.c (OpenSubKey): corrected bug introduced in
+ CONSTification that dropped pointer reference.
+
+ * ChangeLog.2000 (new file):
+ * ChangeLog: broke changes from 2000 into ChangeLog.2000 to reduce
+ size of the main ChangeLog.
+
+2002-01-28 David Gravereaux <davygrvy@pobox.com>
+
+ * generic/tclPlatDecls.h: Added preprocessor logic to force a

+ -Za compiler switch with the microsoft compiler.
+
+2002-01-27 Don Porter <dgp@users.sourceforge.net>

+
+ Make -eofchar and -translation options read only for server sockets.
+ [Bug 496733]
+
+ * generic/tclIO.c (Tcl_GetChannelOption, Tcl_SetChannelOption):
+ Instead of returning nothing for the -translation option on a server
+ socket, always return "auto". Return the empty string enclosed in
+ quotes for the -eofchar option on a server socket. Fixup -eofchar
+ usage message so that it matches the implementation.
+ * tests/io.test: Add -eofchar tests and -translation tests to ensure
+ options are read only on server sockets.
+ * tests/socket.test: Update tests to account for -eofchar and
+ -translation option changes.

+ TCL_ENCODING_END is cleared. As some output was generated the
+ enclosing loop calls UtfToExternal again, again with START set. Three
+ more characters in the out and still no use of input ... To break this
+ infinite loop we remove TCL_ENCODING_START from the set of flags after
+ the first call (no condition is required, the later calls remove an
+ unset flag, which is a no-op). This causes the subsequent calls to
+ UtfToExternal to consume and convert the actual input.

+
+ * generic/tclIOCmd.c (Tcl_GetsObjCmd): Fixed [Bug 504642] as reported
+ by Brian Griffin <bgriffin@users.sourceforge.net>, using his
+ patch. Before the patch the generic I/O layer held an unannounced
+ reference to the interp result to store the read line into. This
+ unfortunately has disastrous results if the channel driver executes a
+ tcl script to perform its operation, this freeing the interp
+ result. In that case we are dereferencing essentially a dangling
+ reference. It is not truly dangling because the object is in the free
+ list, but this only causes us to smash the free list and have the
+ error occur later somewhere else. The patch simply creates a new
+ object for the line and later sets it into the interp result when we
+ are done with reading.

+ - Interactive Tcl_Main can now detect EOF on stdin even in
+ mid-command. [Bug 491341]
+ - Added VFS-aware internal routines for managing the startup script
+ selection.
+ - Tcl variable 'tcl_interactive' is now linked to C variable 'tty'
+ so that one can disable/enable interactive prompts at the script
+ level when there is no startup script. This is meant for use by
+ the test suite.
+ - Consistent use of the Tcl libraries standard channels as returned
+ by Tcl_GetStdChannel(); as opposed to the channels named 'stdin',
+ 'stdout', and 'stderr' in the master interp, which can be
+ different or unavailable.
+ - Tcl_Main now calls Tcl_Exit() if evaluation of [exit] in the
+ master interpreter returns, assuring Tcl_Main does not return.
+ - Documented Tcl_Main's absence from public stub table
+ - Documented that Tcl_Main does not return.
+ - Documented Tcl variables set by Tcl_Main.
+ - All prompts are done from a single procedure, Prompt.
+ - Use of Tcl_Obj-enabled interfaces everywhere.

+
+ * generic/tclCompile.c (TclCompileScript): Added a guard for the

+ infrastructure inserted in them, especially when that infrastructure
+ isn't initialised. [Bug 845412]

+ recently fixed by 2003-11-15 commit to regcomp.c by Pavel Goran. His
+ notes on the fix: This bug results from an error in code that splits
+ states into "progress" and "no-progress" ones. This error causes an
+ interesting situation with the pre-collected single-linked list of
+ states to be splitted: many items were added to the list, but only
+ several of them are accessible from the list beginning, since the
+ "tmp" member of struct state (which is used here to hold a pointer to
+ the next list item) gets overwritten, which results in a "looped"
+ chain. As a result, not all of states are splitted, and one state is
+ splitted two times, causing incorrect "no-progress" flag values.

+2003-11-16 Donal K. Fellows <donal.k.fellows@man.ac.uk>

+ harness to send an asynchronous marking without relying on UNIX
+ signals.

+2003-11-15 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclTest.c (TestHashSystemHashCmd): Removed 'const' modifier
+ from hash type structure; it should be const and the hash code assumes
+ it behaves like const, but that's not how the API is defined. Like
+ this, we are following in the same footsteps as Tcl_RegisterObjType()
+ which has the same conditions on its argument. Stops VC++5.2 warning.

+
+ * generic/tclIOUtil.c

+ * generic/tclCmdIL.c: removed warning on Windows.
+
+2003-11-01 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/tclCmdIL.c (Tcl_LrepeatObjCmd): Check for sensible list
+ lengths and allow for soft failure of the memory subsystem in the
+ [lconcat] command [Bug 829027]. Uses direct list creation to avoid
+ extra copies when working near the limit of available memory. Also
+ reorganized to encourage optimizing compilers to optimize heavily.
+ * generic/tclListObj.c (TclNewListObjDirect): New list constructor
+ that does not copy the array of objects. Useful for creating
+ potentially very large lists or where you are about to throw away the
+ array argument which is being used in its entirety.
+
+2003-10-28 Miguel Sofer <msofer@users.sf.net>
+

+2003-10-23 Andreas Kupries <andreask@activestate.com>
+
+ * unix/tclUnixChan.c (Tcl_MakeFileChannel): Applied [Patch 813606]
+ fixing [Bug 813087]. Detection of sockets was off for Mac OS X which
+ implements pipes as local sockets. The new code ensures that only IP
+ sockets are detected as such.
+
+ * win/tclWinSock.c (TcpWatchProc): Watch for FD_CLOSE too when asked

+ Fixed [Bug 800106] in which 'glob' was incapable of merging the
+ results of a directory listing (real or virtual) and any virtual
+ filesystem mountpoints in that directory (the latter were ignored).
+ This meant boundaries between different filesystems were not seamless
+ (e.g. 'glob */*' across a filesystem boundary was wrong). Added new
+ entry to Tcl_GlobTypeData in a totally backwards compatible way. To
+ allow listing of mounts, registered filesystems must support the
+ 'TCL_GLOB_TYPE_MOUNT' flag. If this is not supported (e.g. in tclvfs
+ 1.2) then mounts will simply not be listed for that filesystem.
+
+ Fixed [Bug 749876] 'file writable/readable/etc' (NativeAccess) using
+ correct permission checking code for Windows NT/2000/XP where more
+ complex user-based security/access priveleges are available,
+ particularly on shared volumes. The performance impact of this extra
+ checking will need further investigation. Note: Win 95,98,ME have no
+ support for this.
+
+ Also made better use of normalized rather than translated paths in the
+ platform specific code.

+
+ * win/tclWinSock.c: Added OpenWatcom to the commentary about the

+
+2003-08-25 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * tools/genStubs.tcl (genStubs::makeDecl): A more subtle way of

+
+ * generic/tcl.decls: Duplicated some namespace declarations from
+ tclInt.decls here, as mandated by TIP #139. This is OK since the

+2003-07-28 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * doc/FileSystem.3:
+ * doc/Translate.3: better documentation of Tcl_TranslateFileName and
+ related functions. [Bug 775220]
+
+2003-07-24 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * generic/tcl.h: Revert change made on 2003-07-21 since it made the
+ sizeof(Tcl_Obj) different for regular vs mem debug builds.
+ * generic/tclInt.h: Define TclDecrRefCount in terms of
+ Tcl_DbDecrRefCount which removes one layer of inderection.
+ * generic/tclObj.c (TclDbInitNewObj, Tcl_DbIncrRefCount,
+ (Tcl_DbDecrRefCount, Tcl_DbIsShared): Define ThreadSpecificData that
+ contains a hashtable. The table is used to ensure that a Tcl_Obj is
+ only acted upon in the thread that allocated it. This checking code is
+ enabled only when mem debug and threads are enabled.
+
+2003-07-24 Don Porter <dgp@users.sourceforge.net>
+
+ * tests/async.test: Added several tests that demonstrate [Bug
+ * tests/basic.test: 489537], Tcl's longstanding failure to
+ * tests/dict.test: properly quote any leading '#' character when
+ * tests/dstring.test: generating the string rep of a list so that
+ * tests/list.test: the comment-power of that character is hidden
+ * tests/parse.test: from any [eval], in order to satisfy the
+ * tests/util.test: documentation that [list] does [eval]-safe
+ quoting.
+
+2003-07-24 Reinhard Max <max@suse.de>
+
+ * library/package.tcl: Fixed a typo that broke pkg_mkIndex -verbose.
+ * tests/pkgMkIndex.test: Added a test for [pkg_mkIndex -verbose].
+
+ * ChangeLog.2002 (new file):
+ * ChangeLog: broke changes from 2002 into ChangeLog.2002 to reduce
+ size of the main ChangeLog.
+
+2003-07-23 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/Makefile.in: changes to html-tcl & html-tk targets for
+ compatibility with non-gnu makes.
+
+ * unix/Makefile.in: added macosx/README to dist target.
+
+2003-07-23 Pat Thoyts <patthoyts@users.sourceforge.net>
+
+ * win/tclWinReg.c (OpenSubKey): Fixed bug 775976 which causes the
+ registry set command to fail when built with VC7.
+ * library/reg/pkgIndex.tcl: Incremented the version to 1.1.2.
+
+2003-07-21 Mo DeJong <mdejong@users.sourceforge.net>
+
+ Check that the thread incrementing or decrementing the ref count of a
+ Tcl_Obj is the thread that originally allocated the thread. This fail
+ fast behavior will catch programming errors that allow a single
+ Tcl_Obj to be accessed from multiple threads.
+
+ * generic/tcl.h (Tcl_Obj): Add allocThread member to Tcl_Obj. This
+ member records the thread id the Tcl_Obj was allocated. It is used to
+ check that any future ref count incr or decr is done from the same
+ thread that allocated the Tcl_Obj. This member is defined only when
+ threads and mem debug are enabled.
+ * generic/tclInt.h (TclNewObj, TclDbNewObj, TclDecrRefCount):
+ Define TclNewObj and TclDbNewObj using TclDbInitNewObj when mem debug
+ is enabled. This fixes a problem where TclNewObj calls did not work
+ the same as TclDbNewObj when mem debug was enabled.
+ * generic/tclObj.c (TclDbInitNewObj, Tcl_DbIncrRefCount,
+ (Tcl_DbDecrRefCount): Add new helper to init Tcl_Obj members when mem
+ debug is enabled. Init the allocThread member in TclDbInitNewObj and
+ check it in Tcl_DbIncrRefCount and Tcl_DbDecrRefCount to make sure a
+ Tcl_Obj allocated in one thread is not being acted upon in another
+ thread.
+
+2003-07-21 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * test/cmdAH.test: ensure certain tests run in local filesystem. [Bug
+ 748960]
+
+2003-07-18 Daniel Steffen <das@users.sourceforge.net>
+
+ * macosx/Makefile: added option to allow installing manpages in
+ addition to default html help.
+
+2003-07-18 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * doc/Utf.3: Tightened up documentation of Tcl_UtfNext and Tcl_UtfPrev
+ to better match the behaviour. [Bug 769895]
+
+2003-07-18 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * library/http/pkgIndex.tcl: upped to http v2.4.4
+ * library/http/http.tcl: add support for user:pass info in URL.
+ * tests/http.test: [Bug 759888] (shiobara)
+
+2003-07-18 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/tcltest.n: Restored the [Eval] proc to replace
+ * library/tcltest/tcltest.tcl: the [::puts] command when either the
+ -output or -error option for [test] is in use, in order to capture
+ data written to the output or error channels for comparison against
+ what is expected. This is easier to document and agrees better with
+ most user expectations than the previous attempt to replace [puts]
+ only in the caller's namespace. Documentation made more precise on
+ the subject. [Bug 706359]
+
+ * doc/AddErrInfo.3: Improved consistency of documentation by
+ * doc/CrtTrace.3: using "null" everywhere to refer to the
+ * doc/Encoding.3: character '\0', and using "NULL" everywhere
+ * doc/Eval.3: to refer to the value of a pointer that points
+ * doc/GetIndex.3: to nowhere. Also dropped references to ASCII
+ * doc/Hash.3: that are no longer true, and standardized on
+ * doc/LinkVar.3: the hyphenated spelling of "null-terminated".
+ * doc/Macintosh.3:
+ * doc/OpenFileChnl.3:
+ * doc/SetVar.3:
+ * doc/StringObj.3:
+ * doc/Utf.3:
+
+ * doc/CrtSlave.3 (Tcl_MakeSafe): Removed warning about possible
+ deprecation (no TIP on that).
+
+2003-07-17 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/tclUnixFCmd.c: fix for compilation errors on platforms where
+ configure detects non-functional chflags(). [Bug 748946]
+
+ * macosx/Makefile: Rewrote buildsystem for Mac OS X framework build
+ to be purely make driven; in order to become independent of Apple's
+ closed-source IDE and build tool. The changes are intended to be
+ transparent to the Makefile user, all existing make targets and cmd
+ line variable overrides should continue to work. Changed build to only
+ include tcl specific html help in Tcl.framework, the tk specific html
+ help is now included in Tk.framework. Added var to allow overriding of
+ tclsh used during html help building (Landon Fuller).
+
+ * macosx/Tcl.pbproj/project.pbxproj:
+ * macosx/Tcl.pbproj/jingham.pbxuser: Changed to purely call through to
+ the make driven buildsystem; Tcl.framework is no longer assembled by
+ ProjectBuilder.
+ Set default SYMROOT in target options to simplify setting up PB
+ (manually setting common build folder for tcl & tk no longer needed).
+
+ * tools/tcltk-man2html.tcl: Added options to allow building only the
+ tcl or tk html help files; the default behaviour with none of the new
+ options is to build both, as before.
+
+ * unix/Makefile.in: Added targets for building only the tcl or tk help
+
+ * macosx/README (new): Tcl specific excerpts of tk/macosx/README.
+
+ * generic/tcl.h: Updated reminder comment about editing
+ macosx/Tcl.pbproj/project.pbxproj when version number changes.
+
+2003-07-16 Mumit Khan <khan@nanotech.wisc.edu>
+
+ * generic/tclPathObj.c (SetFsPathFromAny): Add Cygwin specific code to
+ convert POSIX filename to native format.
+ * generic/tclFileName.c (Tcl_TranslateFileName): And remove from here.
+ (TclDoGlob): Adjust for cygwin and append / for dirs instead of \
+ * win/tclWinFile.c (TclpObjChdir): Use chdir on Cygwin.
+ [Patch 679315]
+
+2003-07-16 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * library/safe.tcl (FileInAccessPath): normalize paths before
+ comparison. [Bug 759607] (myers)
+
+ * unix/tclUnixNotfy.c (NotifierThreadProc): correct size of found and
+ word vars from int to long. [Bug 767578] (hgo)
+
+ * generic/tcl.h: Add recognition of -DTCL_UTF_MAX=6 on the make
+ * generic/regcustom.h: line to support UCS-4 mode. No config arg at
+ this time, as it is not the recommended build mode.
+
+ * generic/tclPreserve.c: In Result and Preserve'd routines, do not
+ * generic/tclUtil.c: assume that ckfree == free, as that is not
+ * generic/tclResult.c: always true. [Bug 756791] (fuller)
+
+2003-07-16 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * doc/CrtSlave.3 (Tcl_MakeSafe): Updated documentation to strongly

+ a bug... [Bug 655300]

+
+2003-07-15 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/dltest/pkga.c (Pkga_EqObjCmd): Fix typo that was causing a
+ crash in load.test.
+
+2003-07-15 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * doc/array.n: Make sure docs are synched with the 8.4 release.
+
+2003-07-15 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/http.n: Updated SYNOPSIS to match actual syntax of commands.
+ [Bug 756112]
+
+ * unix/dltest/pkga.c: Updated to not use Tcl_UtfNcmp and counted
+ strings instead of strcmp (not defined in any #include'd header) and
+ presumed NULL-terminated strings.
+
+ * generic/tclCompCmds.c (TclCompileIfCmd): Prior fix of Bug 711371 on
+ 2003-04-07 introduced a buffer overflow. Corrected. [Bug 771613]
+
+2003-07-15 Kevin B. Kenny <kennykb@acm.org>
+
+ * win/rules.vc: Added a missing $(OPTDEFINES) which broke the build if
+ STATS=memdbg was specified.
+
+2003-07-15 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/tclCmdIL.c (SortCompare): Cleared up confusing error

+
+2003-07-11 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * tests/binary.test (binary-46.*): Tests to help enforce the current
+ behaviour.
+ * doc/binary.n: Documented that [binary format a] and [binary scan a]
+ do encoding conversion by dropping high bytes, unlike the rest of the
+ core. [Bug 735364]
+
+2003-07-11 Don Porter <dgp@users.sourceforge.net>
+
+ * library/package.tcl: Corrected [pkg_mkIndex] bug reported on
+ comp.lang.tcl. The indexer was searching for newly indexed packages
+ instead of newly provided packages.
+
+2003-07-08 Vince Darley <vincentdarley@users.sourceforge.net>

+
+ * doc/expr.n: Tighten up the wording of some operations. [Bug 758488]
+
+ * tests/cmdAH.test: Made tests of [file mtime] work better on FAT
+ filesystems. [Patch 760768] Also a little general cleanup.
+
+ * generic/tclCmdMZ.c (Tcl_StringObjCmd): Made [string map] accept
+ dictionaries for maps. This is much trickier than it looks, since map
+ entry ordering is significant. [Bug 759936]
+
+ * generic/tclVar.c (Tcl_ArrayObjCmd, TclArraySet): Made [array get]
+ and [array set] work with dictionaries, producing them and consuming
+ them. Note that for compatability reasons, you will never get a dict
+ from feeding a string literal to [array set] since that alters the
+ trace behaviour of "multi-key" sets. [Bug 759935]
+
+2003-06-23 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclTrace.c: fix to Window debug build compilation error.
+
+2003-06-27 Don Porter <dgp@users.sourceforge.net>

+
+2003-06-25 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/configure: Regen.
+ * unix/tcl.m4 (SC_CONFIG_CFLAGS): Add -ieee when compiling with cc and

+ 748957]
+
+2003-06-24 Donal K. Fellows <fellowsd@cs.man.ac.uk>

+
+2003-06-24 Donal K. Fellows <fellowsd@cs.man.ac.uk>

+ the twoPtrValue instead of always using the otherValuePtr. Previous
+ fix on 2003-05-12 broke several extensions that wanted to poke around

+2003-05-22 Daniel Steffen <das@users.sourceforge.net>
+
+ * macosx/Tcl.pbproj/project.pbxproj: added missing references to new

+
+ * macosx/tclMacOSXBundle.c: fixed a problem that caused only the first

+
+ * library/encoding/gb2312-raw.enc (new): This is the original

+ * generic/tcl.decls:
+ * macosx/tclMacOSXBundle.c: added extended version of the

+
+ * win/tclAppInit.c (Tcl_AppInit): Fixed memory leaks caused by not
+ freeing the memory allocated by setargv and the async handler created

+ both leaks. In addition, Tcl_AppInit now uses ckalloc instead of
+ Tcl_Alloc to allow for easier leak tracking and to be more consistent
+ with the rest of the Tcl core. [Bugs 733156, 733221]
+

+
+ * generic/tclBasic.c: Implementation of TIP 90, which

+
+ * generic/tclBasic.c: Tcl_EvalObjv() failed to honor the

+
+2003-04-25 Andreas Kupries <andreask@activestate.com>
+
+ * win/tclWinThrd.c: Applied SF patch #727271. This patch changes the
+ code to catch any errors returned by the windows functions handling
+ TLS ASAP instead of waiting to get some mysterious crash later on due
+ to bogus pointers. Patch provided by Joe Mistachkin.
+
+ This is a stop-gap measure to deal with the low number of ?TLS slots
+ provided by some of the variants of Windows (60-80).
+
+2003-04-24 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclFileName.c: fix to bug reported privately by Jeff where,
+ for example, 'glob -path {[tcl]} *' gets confused by the leading
+ special character (which is escaped internally), and instead lists
+ files in '/'. Bug only occurs on Windows where '\' is also a directory
+ separator.
+ * tests/fileName.test: added test for the above bug.
+
+2003-04-22 Andreas Kupries <andreask@activestate.com>
+
+ * The changes below fix SF bugs [593810], and [718045].
+
+ * generic/tclIO.c (Tcl_CutChannel, Tcl_SpliceChannel): Invoke
+ TclpCutSockChannel and TclpSpliceSockChannel.
+
+ * generic/tclInt.h: Declare TclpCutSockChannel and
+ TclpSpliceSockChannel.
+
+ * unix/tclUnixSock.c (TclpCutSockChannel, TclpSpliceSockChannel):
+ Dummy functions, on unix the sockets are _not_ handled specially.
+
+ * mac/tclMacSock.c (TclpCutSockChannel, TclpSpliceSockChannel):
+ * win/tclWinSock.c (TclpCutSockChannel, TclpSpliceSockChannel): New
+ functions to handle socket specific cut/splice operations: auto-init
+ of socket system for thread on splice, management of the module
+ internal per-thread list of sockets, management of association of
+ sockets with HWNDs for event notification.
+
+ * win/tclWinSock.c (NewSocketInfo): Extended initialization
+ assignments to cover all items of the structure. During debugging of
+ the new code mentioned above I found that two fileds could contain
+ bogus data.
+
+ * win/tclWinFile.c: Added #undef HAVE_NO_FINDEX_ENUMS before
+ definition because when compiling in debug mode the compiler complains
+ about a redefinition, and this warning is also treated as an error.
+
+2003-04-21 Don Porter <dgp@users.sourceforge.net>
+
+ * library/tcltest/tcltest.tcl: When the return code of a test does
+ not meet expectations, report that as the reason for test failure, and
+ do not attempt to check the test result for correctness. [Bug 725253]
+
+2003-04-18 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * win/tclWinInt.h (VER_PLATFORM_WIN32_CE): conditionally define.
+ * win/tclWinInit.c: recognize Windows CE as a Win platform. This just
+ recognizes CE - full support will come later.
+
+ * win/configure: regen
+ * win/configure.in (SHELL): force it to /bin/sh as autoconf 2.5x
+ uses /bin/bash, which can fail to find exes in the path (ie: lib).
+
+ * generic/tclExecute.c (ExprCallMathFunc): remove incorrect
+ extraneous cast from Tcl_WideAsDouble.
+
+2003-04-18 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * doc/open.n: Moved serial port options from [fconfigure] to
+ * doc/fconfigure.n: [open] as it is up to the creator of a channel
+ to describe the channel's special config
+ options. [Bug 679010]
+
+2003-04-16 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tcl.h: Made changes so that the "wideInt" Tcl_ObjType
+ * generic/tclObj.c: is defined on all platforms, even those where
+ * generic/tclPort.h: TCL_WIDE_INT_IS_LONG is defined. Also made the
+ Tcl_Value struct have a wideValue field on all platforms. This is a
+ ***POTENTIAL INCOMPATIBILITY*** for TCL_WIDE_INT_IS_LONG platforms
+ because that struct changes size. This is the same TIP 72
+ incompatibility that was seen on other platforms at the 8.4.0 release,
+ when this change should have happened as well. [Bug 713562]
+
+ * generic/tclInt.h: New internal macros TclGetWide() and
+ TclGetLongFromWide() to deal with both forms of the "wideInt"
+ Tcl_ObjType, so that conditional TCL_WIDE_INT_IS_LONG code is confined
+ to the header file.
+
+ * generic/tclCmdAH.c: Replaced most coding that was conditional
+ * generic/tclCmdIL.c: on TCL_WIDE_INT_IS_LONG with code that
+ * generic/tclExecute.c: works across platforms, sometimes using
+ * generic/tclTest.c: the new macros above to do it.
+ * generic/tclUtil.c:
+ * generic/tclVar.c:
+
+2003-04-17 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * doc/socket.n: Added a paragraph to remind people to specify their

+
+2003-04-16 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * doc/CrtMathFnc.3: Functions also have to deal with wide ints, but
+ this was not documented. [Bug 709720]
+
+2003-04-16 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclPathObj.c: removed undesired 'static' for function which
+ is now shared (previously it was duplicated).
+
+2003-04-15 Joe English <jenglish@users.sourceforge.net>
+
+ * doc/namespace.n: added example section "SCOPED SCRIPTS", supplied by
+ Kevin Kenny. [Bug 219183]
+
+2003-04-15 Kevin Kenny <kennykb@acm.org>
+
+ * makefile.vc: Updated makefile.vc to conform with Mo DeJong's changes
+ to Makefile.in and tclWinPipe.c on 2003-04-14. Now passes TCL_PIPE_DLL
+ in place of TCL_DBGX.
+ * win/tclWinTime.c: Corrected use of types to make compilation
+ compatible with VC++5.
+
+2003-04-15 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclIOUtil.c: finished check-in from yesterday, removing
+ duplicate function definition.
+
+2003-04-14 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclClock.c: Corrected compiler warnings.
+ * generic/tclTest.c:
+
+2003-04-14 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * win/Makefile.in: Don't define TCL_DBGX symbol for every compile.
+ Instead, define TCL_PIPE_DLL only when compiling tclWinPipe.c. This
+ will break other build systems, so they will need to remove the
+ TCL_DBGX define and replace it with a define for TCL_PIPE_DLL.
+ * win/tclWinPipe.c (TclpCreateProcess): Remove PREFIX_IDENT and
+ DEBUG_IDENT from top of file. Use TCL_PIPE_DLL passed in from build
+ env instead of trying to construct the dll name from already defined
+ symbols. This approach is more flexible and better in the long run.
+
+2003-04-14 Kevin Kenny <kennykb@acm.org>
+
+ * win/tclWinFile.c: added conditionals to restore compilation on
+ VC++6, which was broken by recent changes.
+
+2003-04-14 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclIOUtil.c:
+ * generic/tclPathObj.c:
+ * generic/tclFileSystem.h: overlooked one function which was
+ duplicated, so this is now shared between modules.
+ * win/tclWinFile.c: allow this file to compile with VC++ 5.2 again
+ since Mingw build fixes broke that.
+
+2003-04-13 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * win/configure: Regen.
+ * win/configure.in: Add check for FINDEX_INFO_LEVELS from winbase.h,
+ known to be a problem in VC++ 5.2. Define HAVE_NO_FINDEX_ENUMS if the
+ define does not exist.
+ * win/tclWinFile.c: Put declarations for FINDEX_INFO_LEVELS and
+ FINDEX_SEARCH_OPS inside a check for HAVE_NO_FINDEX_ENUMS so that
+ these are not declared twice. This fixes the Mingw build.
+ * win/tclWinTime.c: Rework the init of timeInfo so that the number or
+ initializers matches the declaration. This was broken under Mingw. Add
+ cast to avoid compile warning when calling the AccumulateSample
+ function.
+
+2003-04-12 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * win/Makefile.in (GENERIC_OBJS): add missing tclPathObj.c
+
+2003-04-12 Kevin Kenny <kennykb@acm.org>
+
+ * doc/clock.n:
+ * generic/tclClock.c (Tcl_ClockObjCmd):
+ * tests/clock.test: Implementation of TIP #124. Also renumbered test
+ cases to avoid duplicates. [Bug 710310]
+ * tests/winTime.test:
+ * win/tclWinTest.c (TestwinclockCmd, TestwinsleepCmd):
+ * win/tclWinTime.c (Tcl_WinTime, UpdateTimeEachSecond,
+ (ResetCounterSamples, AccumulateSample, SAMPLES, TimeInfo): Made
+ substantial changes to the phase-locked loop (replaced an IIR filter
+ with an FIR one) in a quest for improved loop stability (Bug not
+ logged at SF, but cited in private communication from Jeff Hobbs).
+
+2003-04-11 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclCmdMZ.c (Tcl_StringObjCmd,STR_IS_INT): Corrected
+ inconsistent results of [string is integer] observed on systems where
+ sizeof(long) != sizeof(int). [Bug 718878]
+ * tests/string.test: Added tests for Bug 718878.
+ * doc/string.n: Clarified that [string is integer] accepts 32-bit
+ integers.
+
+2003-04-11 Andreas Kupries <andreask@activestate.com>
+
+ * generic/tclIO.c (UpdateInterest): When dropping interest in
+ TCL_READABLE now dropping interest in TCL_EXCEPTION too. This fixes a
+ bug where Expect detects eof on a file prematurely on solaris 2.6 and
+ higher. A much more complete explanation is in the code itself (40
+ lines of comments for a one-line change :)
+
+2003-04-11 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * tests/cmdAH.test: fix test suite problem if /home is a symlink. [Bug
+ 703264]
+ * generic/tclIOUtil.c: fix bad error message with 'cd ""'. [Bug
+ 704917]
+ * win/tclWinFile.c, win/tclWin32Dll.c:
+ * win/tclWinInt.h: allow Tcl to differentiate between reparse points
+ which are symlinks and mounted volumes, and correctly handle the
+ latter. This involves some elaborate code to find the actual drive
+ letter (if possible) corresponding to a mounted volume. [Bug 697862]
+ * tests/fileSystem.test: add constraints to stop tests running in
+ ordinary tcl interpreter. [Bug 705675]
+
+ * generic/tclIOUtil.c:
+ * generic/tclPathObj.c: (new file)
+ * generic/tclFileSystem.h: (new file)
+ * win/makefile.vc:
+ Split path object handling out of the virtual filesystem layer, into
+ tclPathObj.c. This refactoring cleans up the internal filesystem code,
+ and will make any future optimisations and forthcoming better
+ thread-safety much easier.
+
+ * generic/tclTest.c:
+ * tests/reg.test: added some 'knownBug' tests for problems in Tcl's
+ regexp code with the TCL_REG_CAN_MATCH flag (see Bug 703709). Code too
+ impenetrable to fix right now, but a fix is needed for tip113 to work
+ correctly.
+
+ * tests/fCmd.test
+ * win/tclWinFile.c: added some filesystem optimisation to the 'glob'
+ implementation, and some new tests.
+
+ * generic/tclCmdMZ.c: fix typo in comment
+
+ * tests/winFile.test:
+ * tests/ioUtil.test:
+ * tests/unixFCmd.test: renumbered tests with duplicate numbers. [Bug
+ 710361]
+
+2003-04-10 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * doc/binary.n: Fixed typo in [binary format w] desc. [Bug 718543]
+
+2003-04-08 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/tclCmdAH.c (Tcl_ErrorObjCmd): Strings are only empty if
+ they have zero length, not if their first byte is zero, so fix test
+ guarding Tcl_AddObjErrorInfo to take this into account. [Bug
+ reported by Don Porter; no bug-id.]
+
+2003-04-07 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclCompCmds.c (TclCompileIfCmd): Corrected string limits of
+ arguments interpolated in error messages. [Bug 711371]
+
+ * generic/tclCmdMZ.c (TraceExecutionProc): Added missing
+ Tcl_DiscardResult() call to avoid memory leak.
+
+2003-04-07 Donal K. Fellows <zzcgudf@ernie.mvc.mcc.ac.uk>
+
+ * generic/tclDictObj.c (Tcl_DictObjCmd): Stopped compilers from
+ moaning about switch fall-through. [Bug 716327]
+ (DictFilterCmd): Yet more warning killing, this time reported by
+ Miguel Sofer by private chat.
+
+2003-04-07 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * tests/dict.test (dict-2.6):
+ * generic/tclDictObj.c (Tcl_NewDictObj, Tcl_DbNewDictObj): Oops!
+ Failed to fully initialise the Dict structure.
+ (DictIncrCmd): Moved valueAlreadyInDictionary label to stop compiler
+ complaints. [Bug 715751]
+
+ * generic/tclDictObj.c (DictIncrCmd): Followed style in the rest of
+ the core by commenting out wide-specific operations on platforms where
+ wides are longs, and used longs more thoroughly than ints through
+ [dict incr] anyway to forestall further bugs.
+ * generic/tclObj.c: Made sure there's always a tclWideIntType
+ implementation available, not that it is always useful. [Bug 713562]
+
+2003-04-05 Donal K. Fellows <fellowsd@cs.man.ac.uk>
+
+ * generic/tclDictObj.c: Removed commented out notes on declarations to
+ be moved to elsewhere in the Tcl core.
+
+ * generic/tclInt.h: Final stages of plumbing in.
+ * generic/tclBasic.c:
+ * generic/tclObj.c (TclInitObjSubsystem):
+
+ * unix/Makefile.in, win/Makefile.in, win/makefile.[bv]c: Build support.
+ * generic/tcl.decls: Added dict public API to stubs table.
+ * generic/tcl.h (Tcl_DictSearch): Added declaration of structure to
+ allow user code to iterate over dictionaries.
+
+ * doc/DictObj.3: New files containing dictionary implementation
+ * doc/dict.n: documentation and tests as as mandated by TIP
+ * generic/tclDictObj.c: #111.
+ * tests/dict.test:
+
+2003-04-03 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/configure:
+ * unix/tcl.m4 (SC_CONFIG_CFLAGS): Don't set TCL_LIBS if it is already
+ set to support use of TCL_LIBS var from tclConfig.sh in the Tk
+ configure script.
+
+2003-04-03 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/Makefile.in: Don't subst MATH_LIBS, LIBS, and DL_LIBS
+ separately. Instead, just subst TCL_LIBS since it includes the
+ others.
+ * unix/configure: Regen.
+ * unix/tcl.m4 (SC_CONFIG_CFLAGS, SC_TCL_LINK_LIBS): Set and subst
+ TCL_LIBS in SC_CONFIG_CFLAGS instead of SC_TCL_LINK_LIBS. Don't subst
+ MATH_LIBS since it is now covered by TCL_LIBS.
+ * unix/tclConfig.sh.in: Use TCL_LIBS instead of DL_LIBS, LIBS, and
+ MATH_LIBS.
+ * unix/dltest/Makefile.in: Ditto.
+
+2003-04-03 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclCompCmds.c (TclCompileReturnCmd): Now that [return]
+ compiles to INST_RETURN, it is safe to compile even outside a proc.
+
+2003-04-02 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * win/configure: Regen.
+ * win/configure.in: Set stub lib flag based on new LIBFLAGSUFFIX
+ variable.
+ * win/tcl.m4 (SC_CONFIG_CFLAGS): Set new LIBFLAGSUFFIX that works like
+ LIBSUFFIX, it is used when creating library names. The previous
+ implementation would generate -ltclstub85 instead of -ltclstub85s when
+ configured with --disable-shared.
+
+2003-04-02 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclParse.c (TclSubstTokens): Moved declaration of
+ utfCharBytes to beginning of procedure so that it does not go out of
+ scope (get free()d) while append is still pointing to it. [Bugs
+ 703167, 713754]
+
+2003-04-01 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/configure: Regen.
+ * unix/tcl.m4 (SC_CONFIG_CFLAGS): Check for inet_ntoa in -lbind inside
+ the BeOS block since doing it later broke the build under SuSE 7.3.
+ [Bug 713128]
+
+2003-04-01 Don Porter <dgp@users.sourceforge.net>
+
+ * tests/README: Direct [source] of *.test files is no longer
+ recommended. The tests/*.test files should only be evaluated under the
+ control of the [runAllTests] command in tests/all.tcl.
+
+ * generic/tclExecute.c (INST_RETURN): Bytecompiled [return] failed to
+ reset iPtr->returnCode, causing tests parse-18.17 and parse-18.21 to
+ fail strangely.
+ * tests/parse.test (parse-18.21): Corrected now functioning test.

+ would set the BUFFER_READY flag inside the Tcl_OutputBuffered

+ things: better handling of the switch itself, and integrated

+2003-01-24 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * win/configure: Regen.

+ - fixed some subtle cleanup problems with tracing. This required
+ replacing Tcl_Preserve/Tcl_Release with a more robust refCount

+ - fixed some confusion in the code between new style traces (Tcl
+ 8.4) and the very limited 'Tcl_CreateTrace' which existed before.
+ - made behaviour consistent with documentation (several tests even

+2003-01-13 Mo DeJong <mdejong@users.sourceforge.net>
+
+ Fix mingw build problems and compiler warnings.
+
+ * generic/tcl.h: Add if defined(__MINGW32__) check to code that sets

+ savedTZEnv if we are not going to use them.
+ * generic/tclEnv.c: Add cast to avoid warning.
+ * win/tclWinChan.c: Use DWORD instead of int to avoid compiler warning
+ * win/tclWinThrd.c: Only define allocLock, allocLockPtr, and dataKey

+
+2003-01-12 Mo DeJong <mdejong@users.sourceforge.net>

+
+ * win/configure: Regen.

+
+ * generic/tcl.h: Skip Tcl's define of CHAR, SHORT, and LONG when
+ HAVE_WINNT_IGNORE_VOID is defined. This avoids a bunch of compiler
+ warnings when building with Cygwin or Mingw.
+ * win/configure: Regen.
+ * win/configure.in: Define HAVE_WINNT_IGNORE_VOID when we detect a
+ winnt.h that still defines CHAR, SHORT, and LONG when VOID has already
+ been defined.
+ * win/tcl.m4 (SC_LOAD_TCLCONFIG): Subst the TCL_DEFS loaded from
+ tclConfig.sh so that Tcl defines can make it into the Tk Makefile.
+
+2003-01-12 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * win/configure: Regen.
+ * win/configure.in: Check for typedefs like LPFN_ACCEPT in winsock2.h
+ and define HAVE_NO_LPFN_DECLS if not found.
+ * win/tclWinSock.c: Define LPFN_* typedefs if HAVE_NO_LPFN_DECLS is
+ defined. This fixes the build under Mingw and Cygwin, it was broken by

+ * tests/compile.test: Corrects failure of bytecompiled [catch
+ {return}] to have result TCL_RETURN (not TCL_OK) [Bug 633204]. This
+ patch is a workaround for 8.4.X. A new opcode INST_RETURN is a better
+ long term solution for 8.5 and later.
+
+2003-01-04 David Gravereaux <davygrvy@pobox.com>
+
+ * win/makefile.vc:
+ * win/rules.vc: Fixed INSTALLDIR macro problem that blanked itself by
+ accident causing the install target to put the tree at the root of the
+ drive built on. Whoops..
+
+ Renamed the 'linkexten' option to be 'staticpkg'. Added 'thrdalloc' to
+ allow the switching _on_ of the thread allocator. Under testing, I
+ found it not to be benificial under windows for the purpose of the
+ application I was using it for. It was more important for this app
+ that resources for tcl threads be returned to the system rather than
+ saved/moved to the global recycler. Be extra clean or extra fast for
+ the default threaded build? Let's move to clean and allow it to be
+ switched on for users who find it benificial for their use of threads.

+ * generic/tclProc.c: new static InitCompiledLocals to allow for a

+
+ * generic/tclInterp.c (Tcl_LimitSetTime, TimeLimitCallback):
+ (TclLimitRemoveAllHandlers, TclInitLimitSupport): Set a timer event to
+ trigger when the time limit runs out. All the time limit actually does
+ is check to see if the time limit has been exceeded, but this is
+ enough to fix [Bug 1085023].
+ * generic/tclInt.h (struct Interp): Added a field to hold the token

+ Tcl_PushCallFrame and Tcl_PopCallFrame, but using frames allocated in
+ the execution stack - i.e., heap instead of C-stack. The core uses
+ these two new functions exclusively; the old ones remain for backwards

+ overlooked.

+ to a memory leak. [Bug 1077474].
+
+2004-12-02 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclPathObj.c: fix and new tests for [Bug 1074671] to ensure
+ * tests/fileSystem.test: tilde paths are not returned specially by
+ 'glob'.
+
+2004-12-02 Kevin B. Kenny <kennykb@acm.org>
+
+ * win/Makefile.in: Added a 'sed' in the setting of ROOT_DIR_NATIVE to
+ compensate for a bug in cygpath (at least version 1.36) that leaves a
+ trailing backslash on the end of the converted path.
+
+2004-12-02 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclInterp.c (Alias,Target,Master): Rewrote these so that the
+ aliases that refer to an interpreter are stored in a list and not a
+ hashtable (which was only ever a convenience, and forced the use of a
+ global mutex to generate keys!) [FRQ 1077210]
+ * generic/tclNamesp.c (numNsCreated): Moved into thread-local storage
+ to remove a global mutex. [FRQ 1077210]
+
+2004-12-01 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclUtil.c (TclGetProcessGlobalValue): Narrowed the scope of
+ mutex locks.
+
+ * generic/tclUtil.c: Updated Tcl_GetNameOfExecutable() to
+ * generic/tclEncoding.c: make use of a ProcessGlobalValue for
+ * generic/tclEvent.c: storing the executable name. Added
+ internal routines Tcl(Get|Set)ObjNameOfExecutable() to access that
+ storage in Tcl_Obj, rather than string format.
+
+ * unix/tclUnixFile.c: Rewrote TclpFindExecutable() to use
+ * win/tclWinFile.c: TclSetObjNameOfExecutable to store the
+ executable name it computes.
+
+ * generic/tclInt.h: Added internal stub entries for
+ * generic/tclInt.decls: TclpFindExecutable and
+ Tcl(Get|Set)ObjNameOfExecutable.
+
+ * generic/tclIntDecls.h: make genstubs
+ * generic/tclStubInit.c:
+
+ * generic/tclCmdIL.c: Retrieve executable name in Tcl_Obj form
+ * win/tclWinPipe.c: instead of string form.
+
+ * unix/tclUnixTest.c: Update [testfindexecutable] command to use new
+ internal interfaces.
+
+ * generic/tclEncoding.c: Moved TclpSetInitialEncodings() call
+ from Tcl_FindExecutable() into TclInitEncodingSubsystem(). This is
+ important on Windows where it establishes whether the "ascii" or
+ "unicode" set of system routines will be used, and that needs to be
+ done earlier to support filesystem operations. [Bug 1077005]
+
+2004-12-01 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * tests/winDde.test: Rewritten to use tcltest2 features more
+ thoroughly (reducing the [catch] count!) and fix the problem with
+ winDde-6.1 being out of synch with the implementation.
+
+2004-11-30 Don Porter <dgp@users.sourceforge.net>
+
+ * library/init.tcl ([unknown]): Restored the save/restore of the
+ variables ::errorCode and ::errorInfo. This is needed when the
+ [::bgerror] command is auto-loaded (as it is by Tk).
+
+ Patch 976520 reworks several of the details involved with
+ startup/initialization of the Tcl library, focused on the activities
+ of Tcl_FindExecutable().
+
+ * generic/tclIO.c: Removed bogus claim in comment that encoding
+ "iso8859-1" is "built-in" to Tcl.
+
+ * generic/tclInt.h: Created a new struct ProcessGlobalValue,
+ * generic/tclUtil.c: routines Tcl(Get|Set)ProcessGlobalValue, and
+ function type TclInitProcessGlobalValueProc. Together, these take care
+ of the housekeeping for "values" (things that can be held in a
+ Tcl_Obj) that are global across a whole process. That is, they are
+ shared among multiple threads, and epoch and mutex protection must
+ govern the validity of cached copies maintained in each thread.
+
+ * generic/tclNotify.c: Modified TclInitNotifier() to tolerate being
+ called multiple times in the same thread.
+ * generic/tclEvent.c: Dropped the unused argv0 argument to
+ TclInitSubsystems(). Removed machinery to unsure only one
+ TclInitNotifier() call per thread, now that that is safe. Converted
+ Tcl(Get|Set)LibraryPath to use a ProcessGlobalValue, and moved them to
+ tclEncoding.c.
+ * generic/tclBasic.c: Updated caller.
+
+ * generic/tclInt.h: TclpFindExecutable now returns void.
+ * unix/tclUnixFile.c:
+ * win/tclWinFile.c:
+ * win/tclWinPipe.c:
+
+ * generic/tclEncoding.c: Built new encoding search initialization on a
+ foundation of ProcessGlobalValues, exposing new routines
+ Tcl(Get|Set)EncodingSearchPath. A cache of a map from encoding name to
+ directory pathname keeps track of where encodings are available for
+ loading. Tcl_FindExecutable greatly simplified into just three
+ function calls. The "library path" is now misnamed, as its only
+ remaining purpose is as a foundation for the default encoding search
+ path.
+
+ * generic/tclInterp.c: Inlined the initScript that is evaluated by
+ Tcl_Init(). Added verification after initScript evaluation that Tcl
+ can find its installed *.enc files, and that it has initialized
+ [encoding system] in agreement with what the environment expects.
+ [tclInit] no longer driven by the value of $::tcl_libPath; it largely
+ constructs its own search path now, rather than attempt to share one
+ with the encoding system.
+
+ * unix/tclUnixInit.c: TclpSetInitialEncodings factored so that a new
+ * win/tclWinInit.c: routine TclpGetEncodingNameFromEnvironment can
+ reveal that Tcl thinks the [encoding system] should be, even when an
+ incomplete encoding search path, or a missing *.enc file won't allow
+ that initialization to succeed. TclpInitLibraryPath reworked as an
+ initializer of a ProcessGlobalValue.
+
+ * unix/tclUnixTest.c: Update implementations of [testfindexecutable],
+ [testgetdefenc], and [testsetdefenc].
+
+ * tests/unixInit.test: Corrected tests to operate properly even when
+ a value of TCL_LIBRARY is required to find encodings.
+
+ * generic/tclInt.decls: New internal stubs: TclGetEncodingSearchPath,
+ TclSetEncodingSearchPath, TclpGetEncodingNameFromEnvironment. These
+ are candidates for public exposure by future TIPs.
+
+ * generic/tclIntDecls.h: make genstubs
+ * generic/tclStubInit.c:
+
+ * generic/tclTest.c: Updated [testencoding] to use
+ * tests/encoding.test: Tcl(Get|Set)EncodingSearchPath. Updated tests.
+
+2004-11-30 Kevin B. Kenny <kennykb@acm.org>
+
+ * library/clock.tcl: Corrected the regular expressions that match a
+ time zone to allow for time zones specified as +HH or -HH.
+ * tests/clock.test: Added regression test case for the above issue.
+ Thanks to Rolf Ade for reporting this issue [http://wiki.tcl.tk/13094]
+ * win/tclWinDde.c (Tcl_DdeObjCmd): Corrected a typo that caused a
+ compilation failure on VC++.
+
+2004-11-29 Andreas Kupries <andreask@activestate.com>
+
+ * win/Makefile.in (install-libraries): Brought entry '2004-10-26 Don
+ Porter (Tcl Modules)' into the windows world, actually the
+ win/configure buildsystem. The other windows buildsystems (.vc, .bc)
+ still have to be updated as well.
+
+2004-11-26 Andreas Kupries <andreask@activestate.com>
+
+ * win/tclWinDde.c (ExecuteRemoteObject): Removed bogus semicolon found
+ at the end of the header for the function definition, terminating it
+ early and preventing a compile. This is likely a fix for '2004-11-25
+ Donal'. I have to conclude that it is also unknown if the other
+ changes to this file actually pass the testsuite. Running testsuite
+ ... They don't. winDde-6.1 fails. This is only a message discrepance,
+ i.e. not too bad. Leaving resolution of that to Pat and Donal.
+
+2004-11-26 Don Porter <dgp@users.sourceforge.net>
+
+ * library/auto.tcl (tcl_findLibrary): Made sure the uniquifying
+ operations on the search path does not also normalize. [Bug 1072136]
+
+2004-11-26 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * unix/configure.in: Simplify the code to check for correctness of
+ strstr, strtoul and strtod.
+ * unix/tcl.m4 (SC_TCL_CHECK_BROKEN_FUNC): Split a complex stanza out
+ of configure.in into its own function. Also force it to do the right
+ thing with cacheing of results of AC_TRY_RUN to deal with issue raised
+ in [Patch 1073524]
+
+ * doc/foreach.n: Added simple example. [FRQ 1073334]
+
+2004-11-25 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclProc.c (TclObjInterpProc): Make it so that only
+ * generic/tclIndexObj.c (Tcl_WrongNumArgs): [proc] instances do
+ * tests/indexObj.test (indexObj-5.7): quoting of their first
+ arguments, so keeping [Bug 942757] fixed and making [Bug 1066837] be
+ fixed as well. Done with a load of #ifdef-ery because this hack is so
+ ugly nobody should keep it around once Itcl's fixed.
+
+2004-11-25 Reinhard Max <max@suse.de>
+
+ * tests/tcltest.test: The order in which [glob] returns the file names
+ is undefined, so tests should not depend on it.

+
+ * doc/dde.n: Synchronized the documentation of the commands with the
+ header of the docs and what the package actually does. Thanks to
+ Andreas Kupries for spotting this.
+ * win/tclWinDde.c (Tcl_DdeObjCmd): Much cleanup of argument parsing
+ code.
+
+2004-11-24 David Gravereaux <davygrvy@pobox.com>
+
+ * generic/tclPort.h: Relative include of tclWinPort.h returned as it
+ was requiring me set -I$(tcl_root)/win for my extensions that need to
+ include tclInt.h and doesn't appear to serve any purpose for windows
+ builds.
+
+2004-11-24 Kevin B. Kenny <kennykb@acm.org>
+
+ * unix/tcl.m4 (SC_ENABLE_THREADS): Corrected bad check for 3-argument
+ readdir_r [Bug 1001325].
+ * unix/configure: Regenerated.
+ * unix/tclUnixNotfy.c: Corrected all uses of 'select' to manage their
+ masks using the FD_CLR, FD_ISSET, FD_SET, and FD_ZERO macros rather
+ than bit-whacking that failed under Solaris-Sparc-64. [Bug 1071807]
+ * win/tclWinInit.c (TclpInitLibraryPath): Removed unused vars 'pathc'
+ and 'pathv' that caused compilation problems on VC++ with
+ --enable-symbols.
+
+2004-11-24 Don Porter <dgp@users.sourceforge.net>
+
+ * unix/tcl.m4 (SC_ENABLE_THREADS): Corrected failure to determine the
+ number of arguments for readdir_r on SunOS systems. [Bug 1071701]
+
+ * unix/configure: autoconf-2.57
+
+ * generic/tclCmdIL.c (InfoVarsCmd): Corrected segfault in new

+
+2004-11-24 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * tools/man2html.tcl, tools/man2html1.tcl: Update to use Tcl 8.4.

+
+2004-11-23 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * unix/Makefile.in: Add (commented-out) code to integrate tclConfig.h
+ into the dependency tree and 'make distclean'. [Bug 1068171]
+
+ * generic/tclResult.c (Tcl_AppendResultVA): Remove call to
+ Tcl_GetStringResult to speed up repeated calls to Tcl_AppendResult
+ with the side effect that code that wants to access interp->result
+ should always call Tcl_GetStringResult first. See [Patch 1041072]
+ discussion for more details.
+
+2004-11-22 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * unix/configure: Regen.
+ * unix/tcl.m4 (SC_TCL_64BIT_FLAGS): Define HAVE_TYPE_OFF64_T only when
+ off64_t, open64(), and lseek64() are defined. IRIX 5.3 is known to not
+ include an open64 function. [Bug 1030465]

+ of readdir_r. [Bug 1001325]
+
+2004-11-22 Don Porter <dgp@users.sourceforge.net>
+
+ * unix/tclUnixInit.c (TclpInitLibraryPath): Purged dead code that used
+ * win/tclWinInit.c (TclpInitLibraryPath): to extend the "library
+ path". Search path construction for init.tcl is now done within the
+ [tclInit] proc.
+ * generic/tclInterp.c: Restored several directories to the search
+ * tests/unixInit.test: path used to locate init.tcl within [tclInit].
+ This change does not restore any directories to the encoding search
+ path, so should still avoid the price of an unreasonably large number
+ of filesystem accesses during encoding initialization at startup
+ [Bug 976438]

+
+2004-11-18 Reinhard Max <max@suse.de>
+
+ * unix/tcl.m4 (SC_CONFIG_MANPAGES): Applied an improved version of
+ * unix/configure.in: [Patch 996085], that introduces
+ * unix/Makefile.in: --enable-man-suffix.
+
+ * unix/installManPage: added
+ * unix/mkLinks.tcl: removed
+ * unix/mkLinks: removed
+ * unix/configure: generated
+
+ * unix/Makefile.in: Don't install tclConfig.h .
+
+2004-11-17 Don Porter <dgp@users.sourceforge.net>
+
+ * unix/configure.in: The change below reveals that the public data
+ type Tcl_StatBuf relies on config information. For now, disabled the
+ use of the tclConfig.h file until its full impact on Tcl's interface
+ can be assessed.
+
+ * unix/configure: autoconf-2.57
+
+ * generic/tcl.h: Moved the #include "tclConfig.h" out of
+ * generic/tclInt.h: tcl.h. The config settings are not part of
+ * generic/tclPort.: the public interface, and having it there
+ breaks compiled against uninstalled Tcl and extensions using
+ autoconf-2.5*.
+
+2004-11-16 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * unix/tclUnixChan.c (TtySetOptionProc): fixed crash configuring
+ -ttycontrol on a channel. [Bug 1067708]
+
+2004-11-16 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclIOUtil.c (TclFSEpochOk): There were two code paths via
+ which the thread copy of filesystemEpoch could be synched with the
+ master copy, but only one kept the filesystem list cache up to date.
+ Fix routes everything through a single code path. [Bug 1035775].
+
+2004-11-16 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * unix/tcl.m4 (SC_CONFIG_CFLAGS): Stop architecture flags to 'ld' from

+
+2004-11-16 Daniel Steffen <das@users.sourceforge.net>
+
+ * generic/tcl.h:

+
+ * unix/configure: autoconf-2.57
+
+2004-11-15 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclInt.h: Added comment warning that the old ERR_IN_PROGRESS

+ those extensions that have accessed them.
+
+ * generic/tclCmdMZ.c (Tcl_TraceObjCmd): Fixed Bug 1065378 which failed
+ * tests/trace.test (trace-33.1): to permit a variable trace

+ Thanks to Keith Vetter for the report.
+
+2004-11-15 Donal K. Fellows <donal.k.fellows@man.ac.uk>

+
+2004-11-12 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tclEncoding.c (TableFromUtfProc): correct crash condition

+
+ * doc/interp.n: Basic documentation of the TIP#221 API.
+
+2004-11-12 Don Porter <dgp@users.sourceforge.net>
+
+ TIP #221 IMPLEMENTATION
+ * generic/tclBasic.c: Define [::tcl::Bgerror] in new interps.

+ * generic/tclMain.c:
+
+ * generic/tclDecls.h: make genstubs
+ * generic/tclStubInit.c:
+
+ * unix/tclAppInit.c: Removed tclConfig.h #include, now that tcl.h
+ takes care of it for us.
+
+ * generic/tclInt.h: Moved verification of ptrdiff_t typedef from
+ * generic/tclExecute.c: multiple .c files into one common header where
+ * generic/tclVar.c: it is verifiably after tclConfig.h inclusion.
+
+2004-11-12 Daniel Steffen <das@users.sourceforge.net>
+
+ * generic/tcl.h:
+ * generic/tclInt.h:
+ * unix/Makefile.in: include tclConfig.h from tcl.h and install it as a
+ public header. Normalized compiler include path order to
+ -I${BUILD_DIR} -I${UNIX_DIR} -I${GENERIC_DIR}.
+
+ * unix/dltest/Makefile.in: add ${BUILD_DIR}/.. to include path to pick
+ up tclConfig.h.
+
+ * unix/tclUnixInit.c: moved check for HAVE_CFBUNDLE define after
+ #include "tclInt.h" to ensure tclConfig.h has been included.
+
+2004-11-12 Reinhard Max <max@suse.de>
+
+ * unix/config.h.in:
+ * unix/tclConfig.h.in: renamed
+
+ * unix/Makefile.in: Completed support for config header,
+ * unix/configure.in: fixed building outside of the unix dir,
+ * unix/tclAppinit.c: and reflected the name change of config.h.
+ * generic/tclInt.h:
+
+ * unix/configure: generated
+
+2004-11-12 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * unix/config.h.in: Allow configure to put all the C #defs into
+ * unix/configure.in: a file (called config.h) so that Unix builds
+ * unix/tcl.m4: now take far fewer lines of scrollback to
+ * unix/Makefile.in: proceed (making it less likely that any errors
+ * generic/tclInt.h: or warnings will get missed).
+ * unix/tclAppInit.c: Part of the TIP#34 upgrades.
+
+ * unix/tcl.m4, unix/tclUnixPort.h: Check for pthread_attr_get_np in
+ <pthread.h> before forcing the use of <pthread_np.h> to make things
+ work on NetBSD 2.0. [Bug 1064882]
+
+ * doc/binary.n, doc/upvar.n: More minor fixes.
+
+2004-11-12 Daniel Steffen <das@users.sourceforge.net>
+
+ * doc/CrtChannel.3:
+ * doc/Interp.3:
+ * doc/Limit.3:
+ * doc/binary.n:
+ * doc/dict.n:
+ * doc/tm.n:
+ * doc/upvar.n: fixed *roff errors uncovered by running 'make html'.
+
+ * tools/tcltk-man2html.tcl: added faked support for bullet point
+ lists, i.e. *nroff ".IP \(bu" syntax.
+
+2004-11-11 Daniel Steffen <das@users.sourceforge.net>
+
+ * tests/fCmd.test:
+ * unix/tclUnixFCmd.c (TraverseUnixTree): added option to rewind() the
+ readdir() loop whenever the source hierarchy has been modified by
+ traverseProc (e.g. by deleting files); this is required to ensure
+ complete traversal of the source hierarchy on certain filesystems like
+ HFS+. Added test for failing recursive delete on Mac OS X that was due
+ to this. [Bug 1034337]
+
+ * generic/tclListObj.c (Tcl_ListObjReplace): use memmove() instead of
+ manual copy loop to shift list elements. Decreases time spent in
+ Tcl_ListObjReplace() from 5.2% to 1.7% of overall runtime of tclbench
+ on a ppc 7455 (i.e. 200% speed increase). [Patch 1064243]
+
+ * generic/tclHash.c: hoisted some constant pointer dereferences out of
+ loops to eliminate redundant loads that the gcc optimizer didn't deal
+ with. Decreases time spend in Tcl_FindHashEntry() by 10% over a full
+ run of the tcl testuite on a ppc 7455. [Patch 1064243]
+
+ * tests/fileName.test:
+ * tests/fileSystem.test:
+ * tests/io.test:
+ * tests/msgcat.test:
+ * tests/tcltest.test:
+ * tests/unixInit.test: fixed bugs causing failures when running tests
+ with -tmpdir arg not set to working dir.
+
+ * macosx/Makefile: corrected path to html help inside framework.
+ Prevent parallel make from building several targets at the same time.
+
+ * macosx/tclMacOSXFCmd.c (struct fileinfobuf): force struct to be
+ packed to prevent failures when builing with -malign=natural.
+
+2004-11-10 Andreas Kupries <andreask@activestate.com>
+
+ * unix/tclUnixChan.c: [Bug 727786]. Exterminated the code marked
+ DEPRECATED. This code has not been used in over a year now, and we
+ have no complaints.
+
+2004-11-08 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWinPipe.c: The pipe channel driver now respects the -blocking
+ option when closing is the same way the UNIX side works. This is to
+ avoid a hung shell when exiting due to open pipes that refuse to close
+ in a graceful manner.
+ * doc/open.n: Added a note about -blocking 0 and lack of exit status
+ as it had never been documented. [Bug 947693]
+
+ ***POTENTIAL INCOMPATIBILITY***
+
+ Scripts that use async pipes on windows, must (like the UNIX side) set
+ -blocking to 1 before calling [close] to receive the exit status.
+
+2004-11-07 David Gravereaux <davygrvy@pobox.com>
+
+ * tests/winFile.test: added contraint to winFile-4.0 to prevent it
+ being run on NT4 [Bug 981829]
+
+2004-11-05 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * tests/reg.test: Major reorganization so that this file is much
+ easier for a normal Tcl maintainer to comprehend. The test flags are
+ still very cryptic, but they appear to have to be that way. The number
+ of skipped tests has increased, but now the skipped tests have much
+ more meaningful content.
+
+ * tests/tm.test (genpaths): Add a [file normalize] so we pick up
+ Windows drive letters, etc. [Bug 1053568]
+
+2004-11-04 Don Porter <dgp@users.sourceforge.net>
+
+ * changes: Updates toward an 8.5a2 release.
+
+2004-11-03 Kevin B. Kenny <kennykb@acm.org>
+
+ * library/clock.tcl (FreeScan): Fixed a bug where scanning "Monday"
+ with a base time other than midnight incorrectly carried the base time
+ forward.
+
+ * test/clock.test (clock-33.{5,5a}): Made the test failure more
+ informative.
+
+ * tests/clock.test (clock-34.{28,44,45,46}): Removed 'knownBug'
+ constraints from tests that no longer fail.
+
+ Thanks to Don Porter for reporting these.
+
+2004-11-03 David Gravereaux <davygrvy@pobox.com>
+
+ * generic/tcl.h: Moved the preprocessor logic
+ * generic/tclDecls.h: from tclInt.h of setting the
+ * generic/tclInt.h: TCL_STORAGE_CLASS macro to the
+ * generic/tclIntDecls.h: tcl*Decls.h files now that no
+ * generic/tclIntPlatDecls.h: use of EXTERN is left in tclInt.h.
+ * generic/tclPlatDecls.h: Proto for Tcl_Main moved in tcl.h
+ * win/tclWinPort.h: to prior the inclusion of the Stubs
+ headers as they are now resetting TCL_STORAGE_CLASS. Removed
+ extraineous reset from tclWinPort.h. [Patch 1055668]
+
+ * generic/tclCompile.h: Removed extrainious reset of TCL_STORAGE_CLASS
+ missed in my last edit.
+
+2004-11-03 Don Porter <dgp@users.sourceforge.net>
+
+ * library/init.tcl ([unknown]): Corrections to the 2004-10-25 mods to
+ Aunt ??? in [unknown]. Flaws revealed by Itcl test suite, which still
+ apparently relies on this brokenness. Also added comment suggesting
+ the error message that any code using this hack *ought* to receive in
+ reply.
+
+ * generic/tclTrace.c (TclCallVarTraces): Improved ability to debug
+ * tests/incr-old.test (incr-old-2.6): errors during variable
+ * tests/incr.test (incr-{1,2}.28): traces by preserving the
+ * tests/set.test (set-{2,4}.4): -errorinfo data.
+ * tests/trace.test (trace-33.1): [Bug 527164]
+
+2004-11-02 David Gravereaux <davygrvy@pobox.com>
+
+ * generic/tclInt.h: added a check for #ifdef __cplusplus around the
+ #define of MODULE_SCOPE. About the only time it would be problem is
+ when someone is statically linking to Tcl and accessing internals from
+ a C++ file and has name mangling issues from the lack of "C" after
+ 'extern' [Patch 1055668].
+ * generic/tclCompile.h: Exchanged use of the EXTERN macro to the new
+ MODULE_SCOPE macro. Lowered exported internals count by 35. [Patch
+ 1055668]
+ * win/tclWinInt.h:
+ * win/tclWinPort.h: exported internals dropped by a count of 14.
+ * generic/tclFileSystem.h: Added use of MODULE_SCOPE on protos.
+ * generic/tclRegexp.h: manipulating TCL_STORAGE_CLASS unnecessary.
+
+2004-11-02 Don Porter <dgp@users.sourceforge.net>
+
+ * library/tcltest/tcltest.tcl: Corrected some misleading
+ * tests/tcltest.test (tcltest-26.1,2): displays of ::errorInfo and
+ ::errorCode information when the -setup, -body, and/or -cleanup scripts
+ return an unexpected return code. Thanks to Robert Seeger for the fix.
+ [RFE 1017151].
+
+2004-11-02 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclExecute.c (TclExecuteByteCode): Improved version of the
+ NaN fix from Miguel Sofer. [Bug 761471]
+
+2004-11-02 Kevin Kenny <kennykb@acm.org>
+
+ * library/tzdata/America/Cuiaba: Change to DST rules for
+ * library/tzdata/America/Havana: autumn of 2004.
+ [ftp://elsie.nci.nih.gov/pub/tzdata2004g.tar.gz]
+
+ * tools/tclZIC.tcl: Updated to be compatible with recent changes in
+ library/clock.tcl.
+
+2004-11-02 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * win/tclWinFile.c: Simplify TclpUtime to use Tcl_FSGetNativePath, and
+ add comments.
+
+2004-11-02 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclInt.h: Change uses of EXTERN to MODULE_SCOPE (defined in
+ this file too to be 'extern' if not overridden) as nothing declared in
+ tclInt.h is supposed to be visible outside the Tcl core. If there *is*
+ anything that extensions are actually using, we can open this up later
+ on. [Patch 1055668]
+
+ * doc/CrtChannel.3 (Tcl_GetChannelMode): Add synopsis. [Bug 1058446]
+
+2004-11-01 Kevin B. Kenny <kennykb@acm.org>
+
+ * win/tclWinFile.c (FromCTime, TclpUtime): Replaced a call to the
+ Posix 'utime' function with calls to Windows-API equivalents, to avoid
+ a bug where the VC++ versions misconvert times across a Daylight
+ Saving Time boundary. [Bug 926106]
+ * win/tclWinInt.h (TclWinProcs):
+ * win/tclWin32Dll.c (asciiProcs, unicodeProcs): Removed now-unused
+ reference to 'utime'.
+ * tests/cmdAH.test (cmdAH-24.12): Added test case for the above bug.
+
+2004-11-01 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclExecute.c (TclExecuteByteCode): Make INST_EQ and friends
+ handle NaN correctly in all cases. [Bug 761471]
+
+ * generic/tclNamesp.c (NamespaceInscopeCmd): Make the error message
+ generation the same as in NamespaceEvalCmd().
+ (Tcl_Import): Rationalized to use Tcl_EvalObjv().
+
+2004-10-31 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * tests/io.test (io-40.3): Convert umask2 test constraint into a form
+ that most people will be able to satisfy.
+
+ * tests/cmdAH.test (cmdAH-8.45): Removed broken test constraint. It
+ didn't do what it was intended to do, and it implied the other correct
+ constraint. [Bug 1053908]
+
+ * generic/tclCmdIL.c (InfoGlobalsCmd):
+ * tests/info.test (info-8.4): Strip leading global-namespace
+ specifiers from the pattern argument. [Bug 1057461]
+
+2004-10-30 Kevin Kenny <kennykb@acm.org>
+
+ * generic/clock.c: Replaced WIN32 macro with __WIN32__. [Bug 1054357].
+ Thanks to David Gravereaux for the patch.
+ * win/tclWinFile.c: Removed a long-standing bug that causes incorrect
+ conversion between file time and UTC time if the file time is recorded
+ in a different Daylight Saving Time status than the current one. [Bug
+ 926106]
+
+2004-10-29 Don Porter <dgp@users.sourceforge.net>
+
+ * library/tcltest/tcltest.tcl: Correct reaction to errors in the
+ obsolete processCmdLineArgsHook. [Bug 1055673]
+ * library/tcltest/pkgIndex.tcl: Bump to tcltest 2.2.7
+ * unix/Makefile.in:
+ * tests/all.tcl: Update to use [tcltest::configure].
+
+2004-10-29 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * library/tm.tcl (::tcl::tm::*): Use the core proc engine to generate
+ the wrong-num-args error messages for the path ensemble.
+
+ Ensembles can now (sometimes) rewrite the error messages of their
+ subcommands so they appear more like the arguments that the user
+ passed to the ensemble. Below is a description of changes involved in
+ doing this.
+
+ * tests/namespace.test (namespace-50.*): Tests of ensemble subcommand
+ error message rewriting.
+ * generic/tclProc.c (TclObjInterpProc): Make procedures implement
+ their wrong-num-args message using Tcl_WrongNumArgs instead of
+ something baked-at-home.
+ * generic/tclNamesp.c (TclIsEnsemble, NsEnsembleImplementationCmd):
+ Added test of ensemble-hood (available to rest of core) and made
+ ensembles set up the rewriting for Tcl_WrongNumArgs to take advantage

+
+ * generic/tclInt.decls: The following 9 functions were moved from
+ * generic/tclInt.h: tclInt.h to the private/int Stubs table for
+ * generic/tclIntDecls.h: use by the test suite. As tclTest.obj is
+ * generic/tclStubInit.c: linked to the shell, these functions need
+ "blessed" status so as to always be exported from the library. Being
+ placed in the Stubs table guarantees this [Bug 1054748]:

+ TclpObjCreateDirectory, TclpObjDeleteFile,
+ TclpObjCopyFile, TclpObjRenameFile,
+ TclpObjStat, TclpObjAccess,
+ TclpOpenFileChannel
+
+ * tests/registry.test: Fixed test files to load the correct
+ * tests/winDde.test: registry and dde packages by using the info
+ * win/Makefile.in: from makefiles to tell tcltest where to load
+ * win/makefile.vc: them from. This avoids grabbing the wrong
+ package from $auto_path which might be the install point rather than
+ the dev location. Kudos to Jennifer Hom for adding -load and
+ -loadfile to the tcltest package. [Bug 926088]
+
+ * win/tclWinThrd.c (TclFinalizeLock): release the critical section
+ before deleting it. [Bug 731778]
+
+ * generic/tcl.h: Removed the file level 'extern "C" {' and the
+ coresponding closing block as it serves no purpose given that all the
+ function prototypes have the proper extern usage already.
+
+ * unix/tclAppInit.c: When built as tcltest, TclThread_Init was
+ * win/tclAppInit.c: getting called twice. First by Tcltest_Init,
+ then again in Tcl_AppInit. The call from Tcl_AppInit is now removed.
+

+
+ * generic/tclPipe.c (TclCleanupChildren): bad cast of resolvedPid

+ [Patch 767676]
+
+2004-10-26 Andreas Kupries <andreask@activestate.com>
+
+ * library/tm.tcl (::tcl::tm::Defaults): Added a second [file dirname]

+
+ * unix/Makefile.in (install-libraries): Updated the installation of

+
+2004-10-26 Kevin B. Kenny <kennykb@acm.org>
+
+ * library/clock.tcl (FreeScan): Fixed a bug that caused relative days
+ of the week in free-form [clock scan] to be evaluated in the wrong
+ time zone.
+ * tests/clock.test (clock-31.[456]): Made sure that there isn't an
+ env(TZ) or env(TCL_TZ) lying around that will override the time zone
+ that we're trying to establish with the simulated registry.
+ Both problems reported as [Bug 1054101].
+
+2004-10-25 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * doc/string.n (map): Rewrote to clarify that we don't just map single

+ * doc/info.n (procs): Clarified that the pattern argument may have
+ namespace separators in it. [Bug 1047928]

+ for [Bug 1053908] will become clearer.
+
+2004-10-25 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclExecute.c (IllegalExprOperandType,TclExecuteByteCode):
+ Removed several DECACHE_INFO/CACHE_INFO pairs that are no longer
+ needed for protection because routines like Tcl_SetErrorCode() and
+ Tcl_AddErrorInfo() can no longer re-enter bytecode execution.
+
+ * generic/tclResult.c (TclProcessReturn): Bug fix. Be sure that a
+ missing -errorinfo option when code == TCL_ERROR causes the errorInfo
+ field to get reset.
+
+ * tests/thread.test (thread-4.4): Test depended on a ::errorInfo value
+ initialized to "". Added code to test to setup that requirement.
+
+ * library/auto.tcl: Purged Tcl's script library of all
+ * library/clock.tcl: remaining references to global vars
+ * library/init.tcl: ::errorInfo and ::errorCode.
+
+ * generic/tclMain.c (Tcl_Main): Updated to make use of
+ TclGetReturnOptions instead of ::errorInfo variable.
+
+ * generic/tclInterp.c (tclInit): Bug fix. Access dict variables with
+ [dict get], not array syntax.
+
+2004-10-25 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * tests/tm.test: Rewrote the tests to actually perform syntax checks

+ that the test suite is not complete yet.
+ * library/tm.tcl (path): Rewrote to turn this command into an ensemble
+ to make it faster and simpler.

+
+ * generic/tclCmdIL.c:
+ * generic/tclExecute.c:

+
+2004-10-24 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclBasic.c (Tcl_LogCommandInfo,Tcl_AddObjErrorInfo): Shift

+ to do more often than not.
+
+2004-10-22 Kevin B. Kenny <kennykb@acm.org>
+
+ * library/clock.tcl: Fixed a typo where the fallback time zone became

+ * tests/clock.test: Added regression test cases that covers both bugs.
+ Thanks to Todd M. Helfter <tmh@jumpgate.itsp.purdue.edu> for finding

+2004-10-22 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclVar.c: fixed bug in commit of 2004-07-23, which was

+
+ * generic/tclInt.h (Interp):
+ * generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp):
+ * generic/tclResult.c (GetKeys,ReleaseKeys,etc.): Moved the key values
+ of the return options dictionary out of private fields of the Interp
+ struct and into thread-static values managed in tclResult.c.
+
+ * generic/tclCmdAH.c (Tcl_CatchObjCmd, Tcl_ErrorObjCmd): Updated to

+ work.
+
+ * generic/tclInt.h (TclGetReturnOptions,TclSetReturnOptions):
+ * generic/tclResult.c (TclGetReturnOptions,TclSetReturnOptions): New

+
+ * generic/tclCmdMZ.c (TclProcessReturn,TclMergeReturnOptions):

+ * generic/tclBasic.c (Tcl_CreateInterp, Tcl_DeleteInterp):
+ * generic/tclResult.c (TclTransferResult): Rework so that

+ * generic/tclResult.c (TclRestoreInterpState): Plug potential memory
+ leak.
+
+2004-10-21 Kevin B. Kenny <kennykb@acm.org>
+
+ * generic/tclBasic.c: Various changes to [clock format] that,
+ * generic/tclClock.c: together, make it roughly twice as fast
+ * generic/tclInt.h: while all tests in the test suite
+ * library/clock.tcl: continue to pass.
+
+2004-10-20 Andreas Kupries <andreask@activestate.com>
+
+ * win/Makefile.in (install-msgs): Fixed a problem with the
+ * win/Makefile.in (install-tzdata): installation of timezone data and
+ message catalogs. They used the installed tcl library directory, not
+ the source library. Before it was installed. Switched to source lib
+ dir. Thanks to Kevin for the help in figuring this out.
+
+2004-10-20 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclThreadTest.c (ThreadEventProc): Corrected subtle bug
+ where the returned (char *) from Tcl_GetStringResult(interp) continued
+ to be used without copying or refcounting, while activity on the
+ interp continued. That's not safe, and recent changes demonstrated the
+ lack of safety with failing tests thread-4.3 and thread-4.5.
+
+2004-10-19 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclDictObj.c (DictWithCmd): Make sure all paths (that are

+
+2004-10-19 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclInt.h (Tcl*InterpState): New internal routines
+ * generic/tclResult.c (Tcl*InterpState): TclSaveInterpState,
+ TclRestoreInterpState, and TclDiscardInterpState are superior
+ replacements for Tcl_(Save|Restore|Discard)Result. Intent is that
+ these routines will be converted to public routines after TIP
+ approval. Interfaces for these routines were shamelessly stolen from
+ Itcl.
+
+ * generic/tclBasic.c (TclEvalObjvInternal):
+ * generic/tclDictObj.c (DictUpdateCmd, DictWithCmd):
+ * generic/tclIOGT.c (ExecuteCallback):
+ * generic/tclTrace.c (Trace*Proc,TclCheck*Traces,TclCallVarTraces):
+ Callers of Tcl_*Result updated to call the new routines. The calls
+ were relocated in several cases to perform save/restore operations
+ only when needed.
+
+ * generic/tclEvent.c (HandleBgErrors):
+ * generic/tclFCmd.c (CopyRenameOneFile): Calls to Tcl_*Result that
+ were eliminated because they appeared to serve no useful purpose,

+
+2004-10-07 Donal K. Fellows <donal.k.fellows@man.ac.uk>

+
+ * generic/tclEncoding.c (LoadTableEncoding): Removed reference to Tcl

+ Continued refactoring of [clock] for TIP 173 changes. Broke the
+ free-form parser apart so that the Bison parser is responsible for
+ only parsing, while clock.tcl handles relative times like "next
+ Thursday", "next January". This change is needed to make timezones
+ other than :localtime and :Etc/UTC work with free-form scanning. This
+ change closes out the issue identified as being "for another day" in
+ my log message of 2004-09-08. The refactored code also eliminates the
+ last known references to TclpStrftime and TclGetDate, so those
+ routines (including compat/strftime.c) have been removed. The
+ refactoring also has the benefit that all storage in the Bison parser
+ is now on the C stack, eliminating any need for mutex protection
+ around [clock scan]. Also, changed the Makefiles so that 'make
+ gendate' is available on Windows as well as Unix.

+ * generic/tclExecute.c: Still left several referebces that are just
+ * generic/tclNamesp.c: too nice on performace to do away with. These
+ changes also resolve an inconsistency in the ::errorInfo values
+ produced by [namespace eval x error foo bar] and [namespace eval x

+
+ * generic/tclClock.c (ClockOldscanObjCmd): Silenced a compiler warning

+ flag revealed by testing the 2004-09-09 commits against Itcl.
+ TCL_NAMESPACE_ONLY now acts as specified in the pre-function comment,
+ forcing resolution in the passed in context namespace. It has been

+ * doc/clock.n: Corrected a buglet in the header information. [Bug

+ * generic/tclClock.c (TclClockMktimeObjCmd): Fixed a bug where the
+ month was scanned incorrectly in -timezone :localtime.
+ * tests/clock.test (clock-34.*,clock-40.1, clock-41.1): Adjusted the
+ clock-34.* test cases so that the consistency check is performed in
+ :localtime rather than the current time zone. This change allows
+ dealing with issues where the C library has a different idea of DST
+ conversion than Tcl. (Real fix would be to break TclGetDate into
+ separate parser and time converter, and do the time conversion in
+ clock.tcl. That's for another day.) Added regression test case for the

+ * generic/tclTimer.c: Removed a premature optimisation that attempted
+ to store the assoc data in the client data; the optimisation caused a
+ bug that [after] would overwrite its imports. [Bug 1016167]
+ * library/clock.tcl (InitTZData, ClearCaches): Changed so that the

+ in case tzdata is absent. [Bug 1019537, 1023779]
+ * library/tzdata/*: Regenerated.
+ * tests/clock.test (clock-31.*, clock-39.1): Corrected a problem where
+ the 'system' locale tests fail on a non-English Windows machine. [Bug
+ 1023761]. Added a test to make sure that alias time zones load
+ correctly. [Bug 1023779].
+ * tests/timer.test (timer-1.1, timer-2.1): Changed to (one hopes!) be
+ more resilient on an overloaded system, if [after 200] sleeps for 300

+ * tools/tclZIC.tcl (writeLinks): Corrected a problem where alias time
+ zone names were written incorrectly, causing them to fail to load at
+ run time. [Bug 1023779].
+ * win/tclWinTime.c (Tcl_GetTime): Eliminated CPUID tests on Win64 -

+ Implementation of TIPs #173 and #209.
+
+ The [clock] command is now a Tcl ensemble, with most of its
+ functionality written in Tcl and callouts to C code only to access
+ low-level functions such as localtime, mktime and tzset.
+
+ In addition to the functionality changes called out in the two TIPs,
+ it is worth noting that the [clock] command in a safe slave
+ interpreter is now an alias to the [clock] command in the master, and
+ that [clock] is otherwise not expected to function entirely correctly
+ in safe interps. C code that simply does Tcl_MakeSafe needs to be
+ aware that [clock] may need special handling. (It appears unlikely
+ that such code actually exists.)
+
+ One incompatibility of note is that if the time zone cannot be
+ determined from the TZ, TCL_TZ environment variables, or from the
+ Windows control panel, so that the C library must be used for date and
+ time conversions, then times outside the range of time_t will fail;
+ they used to return bad data silently.
+
+ Many thanks to all the many people who assisted with testing,
+ debugging, criticism of the specification, and localisation. Deserving
+ of particular mention are Joe English, Clif Flynt, Donal K. Fellows,
+ Jeff Hobbs, Cameron Laird, Arjen Markus, Reinhard Max, Christopher
+ Nelson, Steve Offutt, Donald G. Porter, Pascal Scheffers, Peter da

+
+ * generic/tclEvent.c (Tcl_Finalize): stuffed memory leak incurred by

+ requires much more work and would also require TIP because some

+ this will do.
+
+ * generic/tclNotify.c (TclFinalizeNotifier): Added conditional

+
+2004-06-24 Donal K. Fellows <donal.k.fellows@man.ac.uk>

+
+2004-06-23 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclThreadStorage.c: Corrected type casting errors that led

+2004-06-23 Joe Mistachkin <joe@mistachkin.com>
+
+ * generic/tclThread.c: Implements platform independent thread storage
+ * generic/tclThreadStorage.c: mechanism and fixes associated bugs on
+ platforms where there is limited thread local storage space
+ (Win98/WinNT4). [Patch 976496]
+
+ * generic/tclInt.decls:

+
+2004-06-23 Pat Thoyts <patthoyts@users.sourceforge.net>
+
+ * tests/io.test: Added -force to 18.1 and 18.2. This was failing on
+ WinXP.
+
+ * tests/winFCmd.test: Added a cleanup to winFCmd-16.11 to avoid a
+ failure in 16.12.
+
+ * tests/eofchar.data: Added -kb option to ensure a binary checkout to
+ win32 systems. This fixes a failure in io-61.1
+

+ generate a tclConfig.sh with the nmake build system
+
+2004-06-23 Kevin B. Kenny <kennykb@acm.org>
+
+ * tests/winDde.test (createChildProcess): Added a 200-ms delay (with

+
+ * tests/unixNotfy.test: rewritten to use tcltest::threadReap to

+
+2004-06-17 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclObj.c: Added missing space in panic message.
+
+ * win/tclWinInit.c: Inform [tclInit] about the default library

+2004-06-11 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/Encoding.3: Removed bogus claims about tcl_libPath.
+
+ * generic/tclInterp.c (Tcl_Init): Stopped setting the

+
+ * tests/unixInit.test: Modified test code that made use of
+ tcl_libPath variable.
+
+ * unix/tclUnixInit.c: Stopped setting the tclDefaultLibrary variable,
+ execept on the Mac OS X platform with HAVE_CFBUNDLE. In that
+ configuration we should seek some way to make use of the TIP 59
+ facilities and get rid of that usage of tclDefaultLibrary as well.
+
+ * generic/tclInterp.c: Updated [tclInit] to make $env(TCL_LIBRARY) an

+ on the search path for init.tcl.
+
+ * unix/tclUnixInit.c: The routines Tcl_Init() and TclSourceRCFile()
+ * win/tclWinInit.c: had identical implementations for both win and

+
+2004-06-11 Kevin Kenny <kennykb@acm.org>
+
+ * win/tclAppInit.c: Restored the 'setargv' procedure when compiling
+ with mingw. Apparently, the command line parsing in mingw doesn't work
+ as well as that in vc++, and the result was (1) that winPipe-8.19
+ failed, and (2) that 'make test' would work at all only with

+
+2004-06-10 Zoran Vasiljevic <vasiljevic@users.sf.net>
+
+ * generic/tclIOUtil.c: removed forceful setting of the private cached
+ current working directory rep from within the Tcl_FSChdir(). We
+ delegate this task to the Tcl_FSGetCwd() which does this task anyway.
+ The relevant code is still present but disabled temporarily until the
+ change proves correct. The Tcl test suite passes all test with the
+ given change so I suppose it is good enough.
+
+2004-06-10 Don Porter <dgp@users.sourceforge.net>
+
+ * unix/tclUnixInit.c (TclpInitLibraryPath): Disabled addition of
+ * win/tclWinInit.c (TclpInitLibraryPath): relative-to-executable
+ directories to the library search path. A first step in reform of
+ Tcl's startup process.
+
+ ***POTENTIAL INCOMPATIBILITY***
+ Attempts to directly run ./tclsh or ./tcltest out of a build directory
+ will either fail, or will make use of an installed script library in
+ preference to the one in the source tree. Use `make shell` or `make
+ runtest` instead.
+
+ * tests/unixInit.test: Modified tests to suit above changes.
+
+ * generic/tclPathObj.c: Corrected [file tail] results when operating
+ on a path produced by TclNewFSPathObj(). [Bug 970529]
+
+2004-06-09 Zoran Vasiljevic <vasiljevic@users.sf.net>
+
+ * generic/tclIOUtil.c: partially corrected [Bug 932314]. Also

+ * generic/tclDecls.h: Changes to the tests for clock
+ * generic/tclInt.decls: frequency in Tcl_WinTime so

+ * tests/platform.test (platform-1.3): presumably, a common clock.
+ * win/tclWin32Dll.c (TclWinCPUID): This change necessitated a
+ * win/tclWinTest.c (TestwincpuidCmd) small burst of assembly code
+ * win/tclWinTime.c (Tcl_GetTime): to read CPU ID information,
+ which was added as TclWinCPUID in the internal Stubs. To test this

+2004-05-30 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWinPipe.c:
+ * win/tclWinPort.h: Reworked the win implementation of Tcl_WaitPid to
+ support exitcodes in the 'signed short' range. Even though this range

+
+2004-05-30 Donal K. Fellows <donal.k.fellows@man.ac.uk>

+ * generic/tclVar.c: Moved declarations into #if guards so they only
+ happen when required.
+ * unix/tclUnixPort.h: Guard declaration of strtod() so it is only

+ * unix/tclUnixThrd.c (Tcl_CreateThread): Added declarations
+ * unix/tclUnixTest.c (AlarmHandler): and casts so that
+ * unix/tclUnixChan.c (TtyModemStatusStr): all functions are
+ * generic/tclScan.c (Tcl_ScanObjCmd): defined before use
+ * generic/tclDictObj.c (InvalidateDictChain): and no cross-type
+ * generic/tclCmdMZ.c (Tcl_StringObjCmd): uses are performed.
+
+ The overall effect is to make building with gcc with the additional
+ flags -Wstrict-prototypes -Wmissing-prototypes produce no increase in
+ the total number of warnings (except for main(), which is undeclared
+ for traditional reasons.)
+

+
+ The patch modifies non-documented behaviour, and passes every test in

+ Note that the only behaviour change concerns the creative writing of
+ unset variables. More precisely, which variable will be created when
+ neither a namespace variable nor a global variable by that name
+ exists, as defined by [info vars]. The new behaviour is that the
+ namespace resolution process deems a variable to exist exactly when
+ [info vars] finds it - ie, either it has value, or else it was "fixed"
+ by a call to [variable].
+ Note: this patch was removed on 2002-05-25.

+ * generic/tclVar.c: fix for [Bug 735335]. The use of tclNsVarNameType
+ objs is still disabled, pending resolution of [Bug 736729].
+
+2004-05-21 Miguel Sofer <msofer@users.sf.net>
+
+ * tests/namespace.test (namespace-41.3): removed the {knownBug}
+ constraint: [Bug 231259] is closed since nov 2001, and the fix of [Bug
+ 729692] (INST_START_CMD) makes the test succeed.
+
+2004-05-21 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclExecute.c (TclExecuteByteCode): Move a few declarations a
+ short distance so pre-C99 compilers can cope. Also fix so
+ TCL_COMPILE_DEBUG path compiles...
+
+2004-05-21 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclExecute.c (TclExecuteByteCode): reorganised TEBC
+ automatic variables, defining them in tight blocks instead of at the
+ function level. This has three purposes:
+ - it simplifies the analysis of individual instructions
+ - it is preliminary work to the non-recursive engine
+ - it allows a better register allocation by the optimiser; under
+ gcc3.3, this results in up to 10% runtime in some tests
+
+2004-05-20 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclInterp.c (TclLimitRemoveAllHandlers):
+ * generic/tclBasic.c (DeleteInterpProc):
+ * tests/interp.test (interp-34.7): Ensure that all limit callbacks are
+ deleted when their interpreters are deleted. [Bug 956083]
+
+2004-05-19 Kevin B. Kenny <kennykb@acm.org>
+
+ * win/tclWinFile.c (TclpMatchInDirectory): fix for an issue where
+ there was a sneak path from Tcl_DStringFree to SetErrorCode(0). The
+ result was that the error code could be reset between a call to
+ FindFirstFileEx and the check of its status return, leading to a
+ bizarre error return of {POSIX unknown {No error}}. (Found in
+ unplanned test - no incident logged at SourceForge.)
+
+2004-05-19 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * tests/interp.test (interp-34.3): Rewrite this test to see if a time
+ limit can catch a tight bytecode loop, a maximally aggressive
+ denial-of-service attack.
+ * generic/tclInterp.c (Tcl_LimitCheck): Fix the sense of checks to see
+ whether a time limit has been extended.
+
+ * tests/*.test: Many minor fixes, including ensuring that every test
+ is run (so constraints control whether the test is doing anything) and
+ making sure that constraints are always set using the API instead of
+ poking around inside tcltest's internal datastructures. Also got rid
+ of all trailing whitespace lines from the test suite!
+
+2004-05-19 Andreas Kupries <andreask@activestate.com>
+
+ * generic/tclIO.c: Fixed [SF Tcl Bug 943274]. This is the same problem
+ * generic/tclIO.h: as [SF Tcl Bug 462317], see ChangeLog entry
+ 2001-09-26. The fix done at that time is incomplete. It is possible to
+ get around it if the actual read operation is defered and not executed
+ in the event handler itself. Instead of tracking if we are in an read
+ caused by a synthesized fileevent we now track if the OS has delivered
+ a true event = actual data and bypass the driver if a read finds that
+ there is no actual data waiting. The flag is cleared by a short or
+ full read.
+
+ ***POTENTIAL INCOMPATIBILITY*** for channel drivers.
+
+2004-05-17 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclPathObj.c: fix to (Bug 956063) in 'file dirname'.
+ * tests/cmdAH.test: added test for this bug.
+
+ * doc/FileSystem.3: better documentation of refCount requirements of
+ some FS functions (Bug 956126)
+
+2004-05-19 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclTest.c (TestgetintCmd): Made the tests in get.test check
+ * tests/get.test: Tcl_GetInt() since the core now
+ avoids that function.
+
+2004-05-18 Kevin B. Kenny <kennykb@acm.org>
+
+ * compat/strftime.c (_fmt, ISO8601Week):
+ * doc/clock.n:
+ * tests/clock.test: Major rework to the handling of ISO8601 week
+ numbers. Now passes all the %G and %V test cases on Windows, Linux and
+ Solaris [Bugs 500285, 500389, and 852944]
+
+2004-05-18 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * doc/append.n, doc/upvar.n: Added example.
+
+2004-05-18 David Gravereaux <davygrvy@pobox.com>
+
+ * win/makefile.vc: now generates a tclConfig.sh from Pat Thoyts [Patch
+ 909911]
+
+2004-05-18 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * doc/lsearch.n: Improve clarity (based on [Patch 955361] by Peter
+ Spjuth)
+
+ * tools/man2help2.tcl (macro,SHmacro): Added support for subsection
+ (.SS) header macros.
+
+ * doc/interp.n: Added user documentation for the TIP#143 resource
+ limits and some examples.
+
+ * generic/tclInterp.c (Tcl_LimitCheck, Tcl_LimitTypeReset): Reset the
+ limit-exceeded flag when removing a limit.
+
+2004-05-18 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclExecute.c (TclExecuteByteCode): added comments to
+ classify the variables according to their use in TEBC.
+
+2004-05-17 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * doc/global.n, doc/uplevel.n: Added an example.
+
+ * tests/info.test (info-3.1): Corrected test result back to what it
+ used to be in Tcl 7.* now that command counts are being correctly kept
+
+ * generic/tclExecute.c (TEBC:INST_START_CMD): Make sure that the
+ command-count is always advanced. Allows TIP#143 limits to tell that
+ work is being done.
+
+ * doc/list.n: Updated example to fit with the unified format.
+ * doc/seek.n: Added some examples.
+
+2004-05-17 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * win/tclWinFile.c:
+ * tests/cmdAH.test: fix to (Bug 954263) where 'file executable' was
+ case-sensitive.
+
+2004-05-17 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * doc/OpenFileChnl.3: Documented type of 'offset' argument to Tcl_Seek
+ was wrong. [Bug 953374]
+
+2004-05-16 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclExecute.c (TclExecuteByteCode): remove one level of
+ indirection for compiledLocals addressing.
+
+2004-05-16 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclExecute.c (INST_CALL_FUNC1): bugfix; restored
+ (DE)CACHE_STACK_INFO pair around the call - the user defined math
+ function could cause a recursive call to TEBC.
+
+2004-05-16 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclBasic.c (Tcl_DeleteInterp):
+ * generic/tclExecute.c (INST_START_CMD): interp deletion now modifies
+ the compileEpoch, eliminating the need for the check for interp
+ deletion in INST_START_CMD.
+
+2004-05-16 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclCompile.h:
+ * generic/tclCompile.c:
+ * generic/tclExecute.c: changed implementation of {expand}, last
+ chance while in alpha as ...
+
+ ***POTENTIAL INCOMPATIBILITY***
+ Scripts precompiled with ProComp under previous tcl8.5a versions may
+ malfunction due to changed instruction numbers for
+ INST_LIST_INDEX_IMM, INST_LIST_RANGE_IMM and INST_START_CMD.
+
+2004-05-14 Kevin B. Kenny <kennykb@acm.org>
+
+ * generic/tclInt.decls: Promoted TclpLocaltime and TclpGmtime
+ * generic/tclIntDecls.h: from Unix-specific stubs to the generic
+ * generic/tclIntPlatDecls.h: internal Stubs table. Reran 'genstubs'
+ * generic/tclStubInit.c:
+ * unix/tclUnixPort.h:
+
+ * generic/tclClock.c: Changed a buggy 'GMT' timezone specification
+ to the correct 'GMT0'. [Bug 922848]
+
+ * unix/tclUnixThrd.c: Moved TclpGmtime and TclpLocaltime to
+ unix/tclUnixTime.c where they belong.
+
+ * unix/tclUnixTime.c (TclpGmtime, TclpLocaltime, TclpGetTimeZone,
+ ThreadSafeGMTime [removed],
+ ThreadSafeLocalTime [removed],
+ SetTZIfNecessary, CleanupMemory):
+ Restructured to make sure that the same mutex protects all calls to
+ localtime, gmtime, and tzset. Added a check in front of those calls to
+ make sure that the TZ env var hasn't changed since the last call to
+ tzset, and repeat tzset if necessary. [Bug 942078] Removed a buggy
+ test of the Daylight Saving Time information in 'gettimeofday' in
+ favor of applying 'localtime' to a known value. [Bug 922848]
+
+ * tests/clock.test (clock-3.14): Added test to make sure that changes
+ to $env(TZ) take effect immediately.
+
+ * win/tclWinTime.c (TclpLocaltime, TclpGmtime): Added porting layer
+ for 'localtime' and 'gmtime' calls.
+
+2004-05-14 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclExecute.c:
+ * generic/tclCompile.h: the math functions receive a pointer to top of
+ the stack (tosPtr) instead of the execution environment (eePtr). First
+ step towards a change in the execution stack management - it is now
+ only used within TEBC.
+
+2004-05-13 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ TIP#143 IMPLEMENTATION
+
+ * generic/tclExecute.c (TclCompEvalObj, TclExecuteByteCode):
+ * generic/tclBasic.c (TclEvalObjvInternal): Enable limit checking.
+ * generic/tclInterp.c (Tcl_Limit*): Public limit API.
+ * generic/tcl.decls:
+ * tests/interp.test: Basic tests of command limits.
+
+ * doc/binary.n: TIP#129 IMPLEMENTATION [Patch 858211]
+ * generic/tclBinary.c: Note that the test suite probably has many more
+ * tests/binary.test: failures now due to alterations in constraints.
+
+2004-05-12 Miguel Sofer <msofer@users.sf.net>
+
+ Optimisations for INST_START_CMD [Bug 926164].
+ * generic/tclCompile.c (TclCompileScript): avoid emitting
+ INST_START_CMD as the first instruction in a bytecoded Tcl_Obj. It is
+ not needed, as the checks are done before calling TEBC.
+ * generic/tclExecute.c (TclExecuteByteCode): runtime peephole
+ optimisation: check at INST_POP if the next instruction is
+ INST_START_CMD, in which case we fall through.
+
+2004-05-11 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * doc/split.n, doc/join.n: Updated examples and added more.
+
+2004-05-11 Vince Darley <vincentdarley@users.sourceforge.net>

+
+2004-05-11 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+

+ to the scan command.
+
+2004-05-10 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * doc/scan.n: Added examples.
+
+2004-05-10 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWinPipe.c (BuildCommandLine): Moved non-obvious appending
+ logic to outside the loop and added commentary for its purpose. Also
+ use the existence of contents in the linePtr rather than the scratch
+ DString post the append, as this more clear.
+
+ (TclpCreateProcess): When under NT, with no console, and executing a
+ DOS application, the path priming does not need an ending space as
+ BuildCommandLine() will do this for us.
+
+2004-05-08 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclFileName.c:
+ * generic/tclIOUtil.c: remove some compiler warnings on MacOS X.
+
+2004-05-07 Chengye Mao <chengye.geo@yahoo.com>
+
+ * win/tclWinPipe.c: refixed bug 789040 re-entered in rev 1.41. Let's
+ be careful and don't re-enter previously fixed bugs.
+
+2004-05-08 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * doc/format.n: Added examples.
+
+2004-05-07 Miguel Sofer <msofer@users.sf.net>
+

+
+2004-05-07 Reinhard Max <max@suse.de>
+
+ * generic/tclEncoding.c:
+ * tests/encoding.test: added support and tests for translating

+ representation on input/output [Bug 949905].
+
+2004-05-07 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclFileName.c:
+ * generic/tclIOUtil.c:
+ * generic/tclFileSystem.h:
+ * tests/fileSystem.test: fix for [Bug 943995], in which vfs-registered
+ root volumes were not handled correctly as glob patterns in all
+ circumstances.
+
+2004-05-06 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclInt.h:
+ * generic/tclObj.c (TclFreeObj): made TclFreeObj use the new macro
+ TclFreeObjMacro(), so that the allocation and freeing of Tcl_Obj is
+ defined in a single spot (the macros in tclInt.h), with the exception
+ of the TCL_MEM_DEBUG case.
+ The #ifdef logic for the corresponding macros has been reformulated to
+ make it clearer.

+
+2004-05-05 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * doc/CrtObjCmd.3: Remove reference to Tcl_RenameCommand; there is no
+ such API. [Bug 848440]
+
+2004-05-05 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWinSock.c (SocketEventProc) : connect errors should fire both
+ the readable and writable handlers because this is how it works on
+ UNIX [Bug 794839]
+
+ * generic/tclEncoding.c (TclFinalizeEncodingSubsystem):
+ FreeEncoding(systemEncoding); moved to before the hash table iteration
+ as it was causing a double free attempt under some conditions.
+
+ * win/coffbase.txt: Added the tls extension to the list of preferred
+ load addresses.
+
+2004-05-04 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * tests/fileSystem.test (filesystem-1.39): replace 'file volumes'
+ * tests/fileName.test (filename-12.9,10): lindex with direct C:/

+
+2004-05-03 Miguel Sofer <msofer@users.sf.net>

+
+ * generic/tclCompile.c:
+ * generic/tclInt.h: reverted fix for [Bug 926445] of 2004-04-02,

+ more permanent replacement.
+
+2004-04-30 Kevin B. Kenny <kennykb@acm.org>
+
+ * generic/tclThreadAlloc.c: Added a temporary (or so I hope!)

+
+ * doc/open.n, doc/close.n: Updated (thanks to David Welton) to be

+
+2004-04-24 Daniel Steffen <das@users.sourceforge.net>
+
+ * generic/tclPort.h:
+ * macosx/Makefile:
+ * unix/Makefile.in: followup on tcl header reform [FR 922727]: removed
+ use of relative #include paths in tclPort.h to allow installation of
+ private headers outside of tcl source tree; added 'unix' dir to

+
+2004-04-23 Andreas Kupries <andreask@activestate.com>
+
+ * generic/tclIO.c (Tcl_SetChannelOption): Fixed [SF Tcl Bug 930851].

+
+2004-04-25 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclPathObj.c: fix to [Bug 940281]. Tcl_FSJoinPath will now
+ always return a valid Tcl_Obj when the input is valid.
+ * generic/tclIOUtil.c: fix to [Bug 931823] for a more consistent
+ Tcl_FSPathSeparator() implementation which allows filesystems not to
+ implement their Tcl_FSFilesystemSeparatorProc if they wish to use the

+
+2004-04-23 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWin32Dll.c: Removed my mistake from 4/19 of adding an exit
+ handler to TclWinInit. TclWinEncodingsCleanup called from
+ TclFinalizeFilesystem does the Tcl_FreeEncoding for us.
+
+ * win/tclWinChan.c (Tcl_MakeFileChannel): Case for CloseHandle
+ returning zero and not throwing a
+ RaiseException(EXCEPTION_INVALID_HANDLE) now being done.
+
+2004-04-22 David Gravereaux <davygrvy@pobox.com>
+
+ * generic/tclEvent.c: TclSetLibraryPath's use of caching the stringrep
+ of the pathPtr object to TclGetLibraryPath called from another thread
+ was ineffective if the original's stringrep had been invalidated as
+ what happens when it gets muted to a list.
+
+ * win/tclWinTime.c: If the Tcl_ExitProc (StopCalibration) is called
+ from the stack frame of DllMain's PROCESS_DETACH, the wait operation
+ should timeout and continue.
+
+ * generic/tclInt.h:
+ * generic/tclThread.c:

+
+ * doc/Hash.3: Added note to Tcl_{First,Next}HashEntry docs that

+
+ * doc/bgerror.n: Added example from David Welton. [Patch 939473]

+
+2004-04-19 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWin32Dll.c: Added an exit handler in TclWinInit() so

+
+ * generic/tclEncoding.c: Added FreeEncoding(systemEncoding) in

+2004-04-16 Vince Darley <vincentdarley@users.sourceforge.net>
+

+
+2004-04-15 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclClock.c (Tcl_ClockObjCmd): Minor fault in a [clock
+ clicks] error message.
+
+2004-04-07 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * win/tclWinInit.c (TclpSetInitialEncodings): note that WIN32_CE is
+ also a unicode platform.

+
+2004-04-06 Don Porter <dgp@users.sourceforge.net>
+
+ Patch 922727 committed. Implements three changes:
+
+ * generic/tclInt.h: Reworked the Tcl header files into a clean
+ * unix/tclUnixPort.h: hierarchy where tcl.h < tclPort.h < tclInt.h
+ * win/tclWinInt.h: and every C source file should #include
+ * win/tclWinPort.h: at most one of those files to satisfy its
+ declaration needs. tclWinInt.h and tclWinPort.h also better organized
+ so that tclWinPort.h includes the Windows implementation of
+ cross-platform declarations, while tclWinInt.h makes declarations that
+ are available on Windows only.
+
+ * generic/tclBinary.c (TCL_NO_MATH): Deleted the generic/tclMath.h
+ * generic/tclMath.h (removed): header file. The internal Tcl
+ * macosx/Makefile (PRIVATE_HEADERS): header, tclInt.h, has a
+ * win/tcl.dsp: #include <math.h> directly,
+ and file external to Tcl needing libm should do the same.
+
+ * win/Makefile.in (WIN_OBJS): Deleted the win/tclWinMtherr.c file.
+ * win/makefile.bc (TCLOBJS): It's a vestige from matherr() days
+ * win/makefile.vc (TCLOBJS): gone by.
+ * win/tcl.dsp:
+ * win/tclWinMtherr.c (removed):
+
+ End Patch 922727.
+
+ * tests/unixInit.test (unixInit-3.1): Default encoding on Darwin
+ systems is utf-8. Thanks to Steven Abner (tauvan). [Bug 928808]
+
+2004-04-06 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * tests/cmdAH.test (cmdAH-18.2): Added constraint because
+ access(...,X_OK) is defined to be permitted to be meaningless when
+ running as root, and OSX exhibits this. [Bug 929892]
+
+2004-04-02 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclCompile.c:
+ * generic/tclInt.h: removed the macro TCL_ALIGN() from tclInt.h,
+ replaced by the static macro ALIGN() in tclCompile.c [Bug 926445]
+
+2004-04-02 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclCompile.h: removed redundant #ifdef _TCLINT [Bug 928415],
+ reported by tauvan.
+
+2004-04-02 Don Porter <dgp@users.sourceforge.net>
+
+ * tests/tcltest.test: Corrected constraint typos: "nonRoot" ->
+ "notRoot". Thanks to Steven Abner (tauvan). [Bug 928353]
+
+2004-04-01 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclInt.h: Removed obsolete tclBlockTime* declarations. [Bug
+ 926454]
+
+2004-04-01 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclIOUtil.c: Fix to privately reported vfs bug with 'glob
+ -type d -dir . *' across a vfs boundary. No tests for this are
+ currently possible without effectively moving tclvfs into Tcl's test
+ suite.
+
+2004-03-31 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/msgcat.n: Clarified message catalog file encodings. [Bug 811457]
+ * library/msgcat/msgcat.tcl: Updated internals to make use of [dict]s
+ to store message catalog data and to use [source -encoding utf-8] to
+ access catalog files. Thanks to Michael Sclenker. [Patch 875055, RFE
+ 811459] Corrected [mcset] to be able to successfully set a translation
+ to the empty string. [mcset $loc $src {}] was incorrectly set the $loc
+ translation of $src back to $src. Also changed [ConvertLocale] to
+ minimally require a non-empty "language" part in the locale value. If
+ not, an error raised prompts [Init] to keep looking for a valid locale
+ value, or ultimately fall back on the "C" locale. [Bug 811461].
+ * library/msgcat/pkgIndex.tcl: Bump to msgcat 1.4.1.
+
+2004-03-30 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclHash.c (HashStringKey): Cleaned up. This function is not
+ faster, but it is a little bit clearer.
+ * generic/tclLiteral.c (HashString): Applied logic from HashObjKey.
+ * generic/tclObj.c (HashObjKey): Rewrote to fix fault which hashed
+ every single-character object to the same hash bucket. The new code is
+ shorter, simpler, clearer, and (happily) faster.
+
+2004-03-30 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclExecute.c (TEBC): reverting to the previous method for
+ async tests in TEBC, as the new method turned out to be too costly.
+ Async tests now run every 64 instructions.
+
+2004-03-30 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclCompile.c: New instruction code INST_START_CMD that
+ * generic/tclCompile.h: allows checking the bytecode's validity
+ * generic/tclExecute.c: [Bug 729692] and the interp's readyness
+ * tests/interp.test (18.9): [Bug 495830] before running the command.
+ * tests/proc.test (7.1): It also changes the mechanics of the async
+ * tests/rename.test (6.1): tests in TEBC, doing it now at command
+ start instead of every 16 instructions.
+
+2004-03-30 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclFileName.c: Fix to Windows glob where the pattern is a
+ * generic/tclIOUtil.c: volume relative path or a network share [Bug
+ * tests/fileName.test: 898238]. On windows 'glob' will now return
+ * tests/fileSystem.test: the results of 'glob /foo/bar' and 'glob
+ \\foo\\bar' as 'C:/foo/bar', i.e. a correct absolute path (rather than
+ a volume relative path).
+
+ Note that the test suite does not test commands like
+ 'glob //Machine/Shared/*' (on a network share).
+
+2004-03-30 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclPathObj.c: Fix to filename bugs recently
+ * tests/fileName.test: introduced [Bug 918320].
+
+2004-03-29 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclMain.c (Tcl_Main, StdinProc): Append newline only
+ * tests/basic.test (basic-46.1): to incomplete scripts
+ as part of multi-line script construction. Do not add an extra
+ trailing newline to the complete script. [Bug 833150]
+
+2004-03-28 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclCompile.c (TclCompileScript): corrected possible segfault
+ when a compilation returns TCL_OUTLINE_COMPILE after having grown the
+ compile environment [Bug 925121].
+
+2004-03-27 Miguel Sofer <msofer@users.sf.net>
+
+ * doc/array.n: added documentation for trace-realted behaviour of
+ 'array get' [Bug 449893]
+
+2004-03-26 Don Porter <dgp@users.sourceforge.net>

+ another volume relative bug found while testing.
+
+2004-03-24 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclNamesp.c (NsEnsembleImplementationCmd): Fix messed up
+ handling of strncmp result which just happened to work in some libc
+ implementations. [Bug 922752]
+
+2004-03-23 Donal K. Fellows <donal.k.fellows@man.ac.uk>

+ * tests/clock.test: Added test cases for wrong ISO8601 week number
+ [Bug 500285] and wrong GMT base date [Bug 913513]. Several tests still
+ fail on Windows, and these are actual faults in [clock scan]. Fix is

+ * win/tclWinNotify.c (Tcl_WaitForEvent) : Allows an idling notifier to
+ service "Asynchronous Procedure Calls" from its wait state. Only
+ useful for extension authors who decide they might want to try
+ "completion routines" with WriteFileEx(), as an example. From
+ experience, I recommend that "completion ports" should be used instead

+
+ IMPLEMENTATION OF TIP#100 FROM GEORGIOS PETASIS
+ * generic/tclLoad.c (Tcl_UnloadObjCmd): Implementation.
+ * tests/unload.test: Test suite.
+ * unix/dltest/pkgua.c: Helper for test suite.
+ * doc/unload.n: Documentation.
+ Also assorted changes (mostly small) to several other files.
+
+2004-02-23 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/regc_locale.c (cclass): Buffer was having its size reset
+ instead of being released => memleak. [Bug 902562]
+
+2004-02-21 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclLoad.c (Tcl_LoadObjCmd): Fixed memory leak due to an
+ improper error exit route.
+
+2004-02-20 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWinSock.c (SocketThreadExitHandler): Don't call
+ TerminateThread when WaitForSingleObject returns a timeout.
+ Tcl_Finalize called from DllMain will pause all threads. Trust that
+ the thread will get the close notice at a later time if it does ever
+ wake up before being cleaned up by the system anyway.
+
+2004-02-17 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/tcltest.n:
+ * library/tcltest/tcltest.tcl: Changed -verbose default value to
+ {body error} so that detailed information on unexpected errors in
+ tests is provided by default, even after the fix for [Bug 725253]
+
+2004-02-17 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * tests/unixInit.test (unixInit-7.1):
+ * unix/tclUnixInit.c (TclpInitPlatform): ensure the std fds exist to
+ prevent crash condition [Bug 772288]
+
+2004-02-17 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclCompCmds.c (TclCompileSwitchCmd): Bozo mistake in memory

+
+2004-02-16 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tclTrace.c (TclTraceExecutionObjCmd)
+ (TclTraceCommandObjCmd): fix possible mem leak in trace info.
+
+2004-02-12 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * win/tclWinInit.c (AppendEnvironment): Use the tail component of the
+ passed in lib path instead of just blindly using lib+4. That worked
+ when lib was "lib/..." but fails for other values. Thanks go to
+ Patrick Samson for pointing this out.
+
+2004-02-10 David Gravereaux <davygrvy@pobox.com>
+
+ * win/nmakehlp.c: better macro grepping logic.
+
+2004-02-07 David Gravereaux <davygrvy@pobox.com>
+
+ * win/makefile.vc:
+ * win/rules.vc:
+ * win/tcl.rc:
+ * win/tclsh.rc: Added an 'unchecked' option to the OPTS macro so a
+ core built with symbols can be linked to the non-debug enabled C
+ run-time. As per discussion with Kevin Kenny. Called like this:
+
+ nmake -af makefile.vc OPTS=unchecked,symbols
+
+ This clarifies the meaning of the 'g' naming suffix to mean only that
+ the binary requires the debug enabled C run-time. Whether the binary
+ contains symbols or not is a different condition.
+
+2004-02-06 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/clock.n: Removed reference to non-existent [file ctime].
+
+2004-02-05 David Gravereaux <davygrvy@pobox.com>
+
+ * docs/tclvars.n: Added clarification of the tcl_platform(debug) var
+ that it only refers to the flavor of the C run-time, and not whether
+ the core contains symbols.
+
+2004-02-05 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclFileName.c (SkipToChar): Corrected CONST and type-casting
+ issues that caused compiler warnings.
+
+2004-02-04 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclCmdAH.c (StoreStatData): Removed improper refcount
+ decrement of the varName parameter. This error was causing segfaults
+ following test cmdAH-28.7.
+
+ * library/tcltest/tcltest.tcl: Corrected references to non-existent
+ $name variable in [cleanupTests]. [Bug 833637]
+
+2004-02-03 Don Porter <dgp@users.sourceforge.net>
+
+ * library/tcltest/tcltest.tcl: Corrected parsing of single command
+ line argument (option with missing value) [Bug 833910]
+ * library/tcltest/pkgIndex.tcl: Bump to version 2.2.5.
+
+2004-02-02 David Gravereaux <davygrvy@pobox.com>
+
+ * generic/tclIO.c (Tcl_Ungets): Fixes improper filling of the channel
+ buffer. This is the buffer before the splice. [Bug 405995]
+
+2004-02-01 David Gravereaux <davygrvy@pobox.com>
+
+ * tests/winPipe.test: more pass-thru commandline verifications.
+ * win/tclWinPipe.c (BuildCommandLine): Special case quoting for '{'
+ not required by the c-runtimes's parse_cmdline().
+ * win/tclAppInit.c: Removed our custom setargv() in favor of the work
+ provided by the c-runtime. [Bug 672938]
+
+ * win/nmakehlp.c: defensive techniques to avoid static buffer
+ overflows and a couple envars upsetting invokations of cl.exe and
+ link.exe. [Bug 885537]
+
+ * tests/winPipe.test: Added proof that BuildCommandLine() is not doing
+ the "N backslashes followed a quote -> insert N * 2 + 1 backslashes
+ then a quote" rule needed for the crt's parse_cmdline().
+ * win/tclWinPipe.c: Fixed BuildCommandLine() to pass the new cases.
+
+2004-01-30 David Gravereaux <davygrvy@pobox.com>
+
+ * win/makefile.vc: Use the -GZ compiler switch when building for
+ symbols. This is supposed to emulate the release build better to avoid
+ hiding problems that only show themselves in a release build.
+
+2004-01-29 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclPathObj.c: fix to [Bug 883143] in file normalization
+
+2004-01-29 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * doc/file.n:
+ * generic/tclFCmd.c
+ * generic/tclTest.c
+ * library/init.tcl
+ * mac/tclMacFile.c
+ * tests/fileSystem.test: fix to [Bug 886352] where 'file copy -force'
+ had inconsistent behaviour wrt target files with insufficient
+ permissions, particular from vfs->native fs. Behaviour of '-force' is
+ now always consistent (and now consistent with behaviour of 'file
+ delete -force'). Added new tests and documentation and cleaned up the
+ 'simplefs' test filesystem.
+
+ * generic/tclIOUtil.c
+ * unix/tclUnixFCmd.c
+ * unix/tclUnixFile.c
+ * win/tclWinFile.c: made native filesystems more robust to C code
+ which asks for mount lists.
+
+ * generic/tclPathObj.c: fix to [Bug 886607] removing warning/error
+ with some compilers.
+
+2004-01-28 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclObj.c (SetBooleanFromAny): Rewrite to do more efficient
+ string->bool conversion.
+ Many other minor whitespace/style fixes to this file too.
+
+2004-01-27 David Gravereaux <davygrvy@pobox.com>
+
+ * win/nmakehlp.c: Use '.\nul' as the sourcefile name instead of 'nul'
+ so VC 5.2 doesn't try searching the path for it and failing with a
+ possible dialogbox popping up about having to add a CD to an empty
+ drive. Also added a SetErrorMode() call to disable any dialogs that
+ cl.exe or link.exe might create. [Bug 885537]
+
+2004-01-22 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * doc/file.n: clarified documentation of 'file system' [Bug 883825]
+ * tests/fCmd.test: improved test result in failure case.
+
+2004-01-22 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * tests/fileSystem.test: 3 new tests
+ * generic/tclPathObj.c: fix to [Bug 879555] in file normalization.
+ * doc/filename.n: small clarification to Windows behaviour with
+ filenames like '.....', 'a.....', '.....a'.
+
+ * generic/tclIOUtil.c: slight improvement to native cwd caching on
+ Windows.
+
+2004-01-21 David Gravereaux <davygrvy@pobox.com>
+
+ * doc/Panic.3: Mentions of 'panic' and 'panicVA' removed from the
+ documentation.
+
+2004-01-21 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * doc/FileSystem.3:
+ * generic/tcl.decls:
+ * generic/tclCmdAH.c
+ * generic/tclDecls.h
+ * generic/tclFCmd.c
+ * generic/tclFileName.c
+ * generic/tclFileSystem.h

+ * unix/tclUnixFile.c
+ * win/tclWin32Dll.c
+ * win/tclWinFCmd.c
+ * win/tclWinFile.c
+ * win/tclWinInt.h
+
+ Three main issues accomplished: (1) cleaned up variable names in the
+ filesystem code so that 'pathPtr' is used throughout. (2) applied a
+ round of filesystem optimisation with better handling and caching of
+ relative and absolute paths, requiring fewer conversions. (3)
+ clarifications to the documentation, particularly regarding the
+ acceptable refCounts of objects. Some new tests added. Tcl benchmarks
+ show a significant improvement over 8.4.5, and on Windows typically a
+ small improvement over 8.3.5 (Unix still appears to require
+ optimisation). TCL_FILESYSTEM_VERSION_2 introduced, but for internal
+ use only. There should be no public incompatibilities from these
+ changes. Thanks to dgp for extensive testing.
+
+2004-01-19 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWinPipe.c (Tcl_WaitPid): Fixed a thread-safety problem with
+ the process list. The delayed cut operation after the wait was going
+ stale by being outside the list lock. It now cuts within the lock and
+ does a locked splice for when it needs to instead. [Bug 859820]
+
+2004-01-18 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclCompile.c, generic/tclCompile.h: Two new opcodes,
+ INST_LIST_INDEX_IMM and INST_LIST_RANGE_IMM, that have operand(s) of
+ new type OPERAND_IDX4 which represents indexes into things like lists
+ (and perhaps other things eventually.)
+ * generic/tclExecute.c (TclExecuteByteCode): Implementation of the new
+ opcodes. INST_LIST_INDEX_IMM does a simple [lindex] with either front-
+ or end-based simple indexing. INST_LIST_RANGE_IMM does an [lrange]
+ with front- or end-based simple indexing for both the reference to the
+ first and last items in the range.
+ * generic/tclCompCmds.c (TclCompileLassignCmd): Generate bytecode for
+ the [lassign] command.
+
+2004-01-17 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWinInit.c: added #pragma comment(lib, "advapi32.lib") when
+ compiling under VC++ so we don't need to specify it when linking.
+
+2004-01-17 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclCmdIL.c (Tcl_LassignObjCmd): Add more shimmering
+ protection for when the list is also one of the variables.
+
+ BASIC IMPLEMENTATION OF TIP#57
+ * generic/tclCmdIL.c (Tcl_LassignObjCmd): Implementation of the
+ [lassign] command that takes full advantage of Tcl's object API.
+ * doc/lassign.n: New file documenting the command.
+ * tests/cmdIL.test (cmdIL-6.*): Test suite for the command.
+
+2004-01-15 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWinReg.c: Placed the requirement for advapi.lib into the
+ object file itself with #pragma comment (lib, ...) when built with
+ VC++. This will simplify linking for users of the static library.
+
+ * win/rules.vc: Added new 'fullwarn' to the CHECKS commandline macro;
+ sets $(FULLWARNINGS).
+
+ * win/makefile.vc: Removed 'advapi.lib' from $(baselibs). Added new
+ logic to crank-up the warning levels for both compile and link when
+ $(FULLWARNINGS) is set. Some clean-up with how the resource files are
+ built and how -DTCL_USE_STATIC_PACKAGES is sent when compiling the
+ shells.
+
+ * win/tclAppInit.c: Small change in how TCL_USE_STATIC_PACKAGES is
+ used.
+
+ * win/tcl.rc:
+ * win/tclsh.rc: Some clean-up with how the resource files are built.
+ Fixed 'OriginalFilename' problem that still thought a debug suffix was
+ still 'd', now is 'g'.
+
+2004-01-14 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclDictObj.c (TraceDictPath, DictExistsCmd): Adjusted
+ behaviour of [dict exists] so a failure to look up a dictionary along
+ the path of dicts doesn't trigger an error. This is how it was
+ documented to behave previously... [Bug 871387]
+
+ * generic/tclDictObj.c: Assorted dict fixes from Peter Spjuth relating
+ to [Bug 876170].
+ (SetDictFromAny): Make sure that lists retain their ordering even when
+ converted to dictionaries and back.
+ (TraceDictPath): Correct object reference count handling!
+ (DictReplaceCmd, DictRemoveCmd): Stop object leak.
+ (DictIncrCmd,DictLappendCmd,DictAppendCmd,DictSetCmd,DictUnsetCmd):
+ Simpler handling of reference counts when assigning to variables.
+ * tests/dict.test (dict-19.2): Memory leak stress test
+
+2004-01-13 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Silence compiler warnings.
+
+ Patch 876451: restores performance of [return]. Also allows forms such
+ as [return -code error $msg] to be bytecompiled.
+
+ * generic/tclInt.h: Factored Tcl_ReturnObjCmd() into two pieces:
+ * generic/tclCmdMZ.c: TclMergeReturnOptions(), which can parse the
+ options to [return], check their validity, and create the
+ corresponding return options dictionary, and TclProcessReturn(), which
+ takes that return options dictionary and performs the [return]
+ operation.
+
+ * generic/tclCompCmds.c: Rewrote TclCompileReturnCmd() to call
+ TclMergeReturnOptions() at compile time so the return options
+ dictionary is computed at compile time (when it is fully known). The
+ dictionary is pushed on the stack along with the result, and the code
+ and level values are included in the bytecode as operands. Also
+ supports optimized compilation of un-[catch]ed [return]s from procs
+ with default options into the INST_DONE instruction.
+
+ * generic/tclExecute.c: Rewrote INST_RETURN instruction to retrieve
+ the code and level operands, pop the return options from the stack,
+ and call TclProcessReturn() to perform the [return] operation.
+
+ * generic/tclCompile.h: New utilities include TclEmitInt4 macro
+ * generic/tclCompile.c: and TclWordKnownAtCompileTime().
+
+ End Patch 876451.
+
+ * generic/tclFileName.c (Tcl_GlobObjCmd): Latest changes to management
+ of the interp result by Tcl_GetIndexFromObj() exposed improper interp
+ result management in the [glob] command procedure. Corrected by
+ adopting the Tcl_SetObjResult(Tcl_NewStringObj) pattern. This stopped
+ a segfault in test filename-11.36. [Bug 877677]
+
+2004-01-13 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct, Tcl_WrongNumArgs):
+ Create fresh objects instead of using the one currently in the
+ interpreter, which isn't guaranteed to be fresh and unshared. The cost
+ for the core will be minimal because of the object cache, and this
+ fixes [Bug 875395].
+
+2004-01-12 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclCompExpr.c (CompileLandOrLorExpr): cosmetic changes.
+
+2004-01-12 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclCompExpr.c (CompileLandOrLorExpr): new logic, fewer
+ instructions. As a side effect, the instructions INST_LOR and
+ INST_LAND are now never used.
+ * generic/tclExecute.c (INST_JUMP*): small optimisation; fix a bug in
+ debug code.
+
+2004-01-11 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclWinThrd.c (Tcl_ConditionNotify): condPtr must be dereferenced
+ to see if there are waiters else uninitialized datum is manipulated.
+ [Bug 849007 789338 745068]
+
+2004-01-09 David Gravereaux <davygrvy@pobox.com>
+
+ * generic/tcl.h: Renamed and deprecated #defines moved to within the
+ #ifndef TCL_NO_DEPRECATED block. This allows us to build Tcl to check
+ for deprecated functions in use, such as panic() and Tcl_Ckalloc(). By
+ request from DKF. Extensions that build with -DTCL_NO_DEPRECATED now
+ have these macros as restricted.
+ ***POTENTIAL INCOMPATIBILITY***
+
+ * win/makefile.vc:
+ * win/rules.vc: Added -DTCL_NO_DEPRECATED usage to makefile.vc.
+ Called like this: nmake -af makefile.vc CHECKS=nodep
+
+2004-01-09 Vince Darley <vincentdarley@users.sourceforge.net>
+
+ * generic/tclIOUtil.c: fix to infinite loop in TclFinalizeFilesystem
+ [Bug 873311]

+
+ * libtommath/bn_mp_sqrt.c: Improved the initial approximation to the

+ * doc/socket.n: Cross-referenced the socket documentation better to the
+ fconfigure documentation on the topic of asynch sockets.
+ * doc/fconfigure.n: Added keyword to documentation of -blocking option
+ so that people looking for "asynch" can find it as well.
+
+2005-12-05 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/tclUnixPort.h (Darwin): fix incorrect __DARWIN_UNIX03 configure
+ overrides that were originally copied from Darwin CVS (rdar://3693001)
+
+2005-12-05 Kevin B. Kenny <kennykb@acm.org>
+
+ * tools/tclZIC.tcl: Updated to reflect changes in calling sequence when
+ GetJulianDateFromEraYearMonthDay moved to C.
+ * library/tzdata: Regenerated from Olson's tzdata2005p.tar.gz - the
+ 'systemv' changes appear not to affect Tcl's processing of the dates.
+
+2005-12-05 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/configure.in: move check for fts API to configure.in and run it
+ * unix/tcl.m4: on all platforms, since Linux glibc2 and *BSDs
+ also have this; using fts is more efficient than a recursive
+ opendir/readdir.
+ * unix/tclUnixFCmd.c (TraverseUnixTree): add support to fts code for
+ platforms with stat64.
+ * unix/configure:
+ * unix/tclConfig.h.in: regen.
+
+2005-12-05 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * unix/configure: Use fts file API on Darwin if available.
+ * unix/tcl.m4: Addresses file delete issues in readdir noted
+ * unix/tclUnixFCmd.c: in [Bug 1034337]. (steffen)
+ Remove redundant stat call for each file in DoCopyFile. (steffen)
+
+2005-12-02 Kevin B. Kenny <kennykb@acm.org>
+
+ * generic/tclClock.c: Moved a tiny bit more of [clock format] from run
+ * library/clock.tcl: time to compile time, and fixed a l10n bug in the
+ process. [Bug 1371446]. Also, conditoned the call to SetupTimeZone to
+ speed the common case where TZData($timezone) already exists, and
+ achieved a puny speedup by making ::tcl::clock::getenv not throw
+ errors.
+ * unix/Makefile.in: Made some changes to support a 'make' command that
+ is present on some antiquated versions of Solaris.
+
+2005-12-01 Kevin B. Kenny <kennykb@acm.org>
+
+ * library/clock.tcl: Continued rationalizing the code, eliminating
+ numerous redundant [mc] calls. Added another time boost by precompiling
+ a [::format] command to do the bulk of the work of [clock format].
+
+2005-12-01 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * unix/Makefile.in: Add remaining dependency info. While automated
+ maintenance of this information would be good, having it at all is much
+ better than a poke in the eye with a sharp stick...
+
+2005-12-01 Daniel Steffen <das@users.sourceforge.net>
+
+ * generic/tclClock.c: fix warning.
+
+ * unix/tcl.m4 (Darwin): fix error when MACOSX_DEPLOYMENT_TARGET unset
+ * unix/configure: regen.
+
+2005-11-30 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * unix/Makefile.in: Add dependency information relating to tclCompile.h
+ since when the list of opcodes changes it is usually useful to rebuild
+ everything that depends on it (but which is nonetheless a small
+ fraction of the total set of Tcl source files).
+
+ ***POTENTIAL INCOMPATIBILITY*** for bytecode savers/loaders. See below
+
+ * generic/tclCompCmds.c (TclCompileSwitchCmd): Arrange for very simple
+ [switch] invokations to be compiled into hash lookups into jump tables;
+ only a very specific kind of [switch] can be safely compiled this way,
+ but that happens to be the most common kind. This makes around 5-10%
+ difference to the speed of execution of clock.test.
+ * generic/tclExecute.c (TEBC:INST_JUMP_TABLE): New instruction to allow
+ for jumps to locations looked up in a hashtable. Requires a new AuxData
+ type, tclJumptableInfoType (supported by the functions DupJumptableInfo
+ and FreeJumptableInfo in tclCompCmds.c) so anything that saves bytecode
+ containing this *must* be updated!
+
+2005-11-30 Kevin Kenny <kennykb@acm.org>
+
+ * generic/tclClock.c: Fixed a bad refcount in previous commit that led
+ to a corrupted heap. Also silenced a warning that some compilers gave
+ about the excessively long constant for JULIAN_SEC_POSIX_EPOCH. Also
+ fixed a bug where [clock format] would fail in the :localtime zone for
+ times before the Posix Epoch. Thanks to Miguel Sofer for pointing out
+ all of these. Also rationalized the code a little bit by moving parts
+ of [clock scan] into C, eliminating some code that was duplicated in
+ the C and Tcl layers.
+
+2005-11-29 Kevin Kenny <kennykb@acm.org>
+
+ * generic/tclBasic.c: Moved a big part of [clock format] down
+ * generic/tclClock.c: to the C level in order to make it go faster.
+ * generic/tclInt.h: Preliminary measurements suggest that it
+ * generic/clock.tcl: more than doubles in speed with this change.
+
+2005-11-29 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * generic/tclCmdIL.c (Tcl_LsearchObjCmd): Allow [lsearch -regexp] to
+ process REs that contain backreferences. This expensive mode of
+ operation is only used if the RE would otherwise cause a compilation
+ failure. [Bug 1366683]
+
+2005-11-28 Kevin Kenny <kennykb@acm.org>
+
+ * tools/tclZIC.tcl (convertTimeOfDay): Corrected a typo that caused
+ wrong DST transitions in any time zone where the transition is
+ specified as local Standard Time (as opposed to wall-clock or UTC).
+ (Also updated the code to be bignum-safe.)
+ * tests/clock.test (clock-51.1): Added regression test for the above.
+ * library/tzdata: Updated to Olson's 'tzdata2005o' (changes for Cuba,
+ Nicaragua, Jordan, and Georgia) and regenerated. Thanks to Paul
+ Mackerras for reporting this problem.
+
+2005-11-27 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/tcl.m4 (Darwin): add 64bit support, check for Tiger copyfile(),
+ add CFLAGS to SHLIB_LD to support passing -isysroot in env(CFLAGS) to
+ configure (flag can't be present twice, so can't be in both CFLAGS and
+ LDFLAGS during configure), don't use -prebind when deploying on 10.4,
+ define TCL_IO_TRACK_OS_FOR_DRIVER_WITH_BAD_BLOCKING (rdar://3171542).
+ (SC_ENABLE_LANGINFO, SC_TIME_HANDLER): add/fix caching, fix obsolete
+ autoconf macros. Sync with tk/unix/tcl.m4.
+
+ * unix/configure.in: fix obsolete autoconf macros, sync gratuitous
+ formatting/ordering differences with tk/unix/configure.in.
+
+ * unix/Makefile.in: add CFLAGS to tclsh/tcltest link to make executable
+ linking the same as during configure (needed to avoid losing any linker
+ relevant flags in CFLAGS, in particular flags that cannot be in
+ LDFLAGS). Avoid concurrent linking of tclsh and compiling of
+ tclTestInit.o or xtTestInit.o during parallel make.
+ (checkstubs, checkdoc, checkexports): dependency and Darwin fixes
+ (dist): add new macosx files.
+
+ * unix/tclLoadDyld.c (TclpDlopen): use NSADDIMAGE_OPTION_WITH_SEARCHING
+ on second NSAddImage only. [Bug 1204237]
+ (TclGuessPackageName): should not be MODULE_SCOPE.
+ (TclpLoadMemory): ppc64 and endian (i386) fixes, add support for

+
+ * unix/tclUnixFCmd.c:
+ * macosx/tclMacOSXFCmd.c: ppc64 and endian (i386) fixes.
+ (TclMacOSXCopyFileAttributes): add support for new Tiger copyfile() API
+ to enable copying of xattrs & ACLs by [file copy].
+
+ * generic/tcl.h: add Darwin specifc configure overrides for TCL_WIDE
+ defines to support fat compiles of ppc and ppc64 at the same time,
+ (replaces Darwin CVS fix by emoy, rdar://3693001). add/correct location
+ of version numbers in macosx files.
+
+ * generic/tclInt.h: clarify fat compile comment.
+
+ * unix/tclUnixPort.h: add Darwin specifc configure overrides to support

+ compiles.
+
+ * macosx/README: clarification/cleanup, document new Xcode projects and

+
+ * unix/Makefile.in:
+ * unix/aclocal.m4:
+ * unix/configure.in:
+ * unix/dltest/Makefile.in:
+ * macosx/configure.ac (new file): add support for inclusion of

+ headers enabled configure script in macosx (required by Xcode
+ projects).
+
+ * macosx/GNUmakefile: rename from Makefile to avoid overwriting by
+ configure run in tcl/macosx, add support for reusing configure cache,
+ build target fixes, remove GENERIC_FLAGS override now handled by
+ tcl.m4.
+
+ * generic/tcl.decls: add Tcl_Main declaration as comment to avoid
+ 'checkstubs' target complaining about it missing from stubs.

+2005-11-21 Andreas Kupries <andreask@activestate.com>
+
+ * unix/Makefile.in (install-libraries): Updated Makefile to new
+ * win/Makefile.in (install-libraries): version of the http package.
+ This fixes the ifneeded/provide mismatch reported when trying to
+ require http. Should we maybe try to automatically extract the version
+ number from the http code to prevent future breakage ?
+
+ This follows the update of the version number by dgp on Nov 15 (No

+
+2005-11-18 Miguel Sofer <msofer@users.sf.net>
+
+ * tests/trace.test (trace-34.5): [Bug 1047286], added a second test
+ illustrating the role of "ns in callStack" in the ns's visibility
+ during deletion traces.
+
+2005-11-18 Kevin B. Kenny <kennykb@acm.org>
+
+ * doc/clock.n: Restored several missing lines near the %w format group

+
+2005-11-18 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclObj.c (GetBignumFromObj): replace NULL with

+ (the corresponding branch is eliminated by the optimiser otherwise).
+
+2005-11-18 Andreas Kupries <andreask@activestate.com>
+
+ * generic/tclIO.c (TclFinalizeIOSubsystem): Applied Pat Thoyts' patch
+ for [Bug 1359094]. This moves the retrieval of the next channel state
+ to the end of the loop, as the called closeproc may close other
+ channels, i.e. modify the list we are iterating, invalidating any
+ pointer retrieved earlier.
+
+2005-11-18 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclListObj.c: Restored the SetListFromAny routine to the
+ * generic/tclObj.c: "list" Tcl_ObjType, and restored the
+ Tcl_RegisterObjType() call for "list". This addresses the needs of some
+ "bridge" extensions to examine whether the Tcl_ObjType of a Tcl_Obj is
+ that of the "list" Tcl_ObjType.

+2005-11-12 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclBasic.c (Tcl_DeleteCommandFromToken):

+
+2005-11-12 Donal K. Fellows <dkf@users.sf.net>
+
+ * generic/tclNamesp.c (Tcl_FindCommand): Do not find commands in dead

+
+2005-11-11 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclInt.h: Revised TclParseNumber interface to enable

+ * generic/tclStrToD.c: to permit tests scan-4.44,55 to pass again.
+ [Bug 1348067].
+
+2005-11-11 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclBasic.c (Tcl_DeleteCommandFromToken):
+ * generic/tclObj.c (Tcl_GetCommandFromObj): bump the cmd epoch early
+ to insure that cached references to this command are invalidated.
+ Partial fix for [Bug 1352734] - at least insures that namespace-51.13
+ does not cause a panic. The test is still marked as knownbug, pending
+ resolution of what is actually the correct return value ([Bug
+ 1354540])
+
+2005-11-09 Kevin B. Kenny <kennykb@acm.org>
+
+ * generic/tclTimer.c: Changed [after] so that it behaves correctly

+
+2005-11-08 Don Porter <dgp@users.sourceforge.net>

+
+2005-11-09 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>

+
+ * generic/tclPkg.c: Corrected inconsistencies in the value returned

+
+2005-11-07 Miguel Sofer <msofer@users.sf.net>
+

+
+2005-11-05 Miguel Sofer <msofer@users.sf.net>

+2005-11-04 Kevin Kenny <kennykb@acm.org>
+
+ * generic/tclGetDate.y: Added abbreviations for the Korean

+ * generic/tclDate.c: Regenerated.
+
+ * tools/findBadExternals.tcl: Added this script, which locates external

+
+ * tests/env.test (env-6.1):
+ * win/tclWinPort.h: define USE_PUTENV_FOR_UNSET 1
+ * generic/tclEnv.c (TclSetEnv, TclUnsetEnv): add USE_PUTENV_FOR_UNSET

+
+2005-10-04 Don Porter <dgp@users.sourceforge.net>
+

+
+ * generic/tclUtil.c: Converted the $::tcl_precision value to be kept

+
+ ***POTENTIAL INCOMPATIBILITY*** Multi-threaded programs that set the
+ value of ::tcl_precision will now have to set it in each thread.
+
+ * tests/expr.test: Consolidated equivalent constraints into

+ * tests/listObj.test: empty => emptyTest; winOnly => win
+ * tests/obj.test: intsAre64bit => longIs64bit
+ Also updated some "nonPortable" tests to use constraints that mark
+ precisely what about them isn't portable, so the tests can run where
+ they work.
+
+ * library/init.tcl ([unknown]): Corrected return code handling in the

+ values "0" and "1" are kept as "int" Tcl_ObjType, which also produce

+ means a Tcl_ConvertToType to a "boolean" Tcl_ObjType might not produce
+ a Tcl_Obj of type "boolean", the registration of the "boolean" type is
+ also removed.

+ * tests/listObj.test: registration of the Tcl_ObjType's "list",
+ * tests/obj.test: "procbody", "index", "ensembleCommand",
+ "localVarName", and "levelReference". The only reason to register a
+ Tcl_ObjType is to have it returned by Tcl_GetObjType, and the only
+ reason for that is to retrieve a (Tcl_ObjType *) to pass to
+ Tcl_ConvertToType(). None of the types above can support a
+ Tcl_ConvertToType() call; they panic. Better not to offer something
+ than to lead users into a panic.

+
+ * generic/tclObj.c: Several changes:
+
+ - Re-ordered error detection code so all values with trailing garbage
+ receive a "not an integer" message instead of an "integer too large"
+ message.
+ - Removed inactive code meant to deal with strtoul* routines that fail
+ to parse leading signs. All of them do, and if any are detected that
+ do not, the correct fix is replacement with compat/strtoul*.c, not a
+ lot of special care by the callers.
+ - Tcl_GetDoubleFromObj now avoids shimmering away a "wideInt" intrep.
+ - Fixed Tcl_GetBooleanFromObj to agree with its documentation and with
+ Tcl_GetBoolean, accepting only "0" and "1" and not other numeric
+ strings. [Bug 1187123]
+ - Added new private routine TclGetTruthValueFromObj to perform the more
+ permissive conversion of numeric values to boolean that is needed by
+ the [expr] machinery.
+
+ * generic/tclInt.h (TclGetTruthValueFromObj): New routine.
+ * generic/tclExecute.c: Updated callers to call new routine.
+ * generic/tclBasic.c: Updated callers to call new routine.
+ * generic/tclCompCmds.c: Updated callers to call new routine.
+ * generic/tclDictObj.c: Updated callers to call new routine.
+ * tests/obj.test: Corrected bad tests that actually expected
+ values like "47" and "0xac" to be accepted as booleans.
+
+ * generic/tclLiteral.c: Disabled the code that forces some literals
+ into the "int" Tcl_ObjType during registration. We can re-enable it if
+ this change causes trouble, but it seems more sensible to let Tcl's
+ "on-demand" shimmering rule, and not try to pre-guess things.

+
+ * generic/tclIO.c (Tcl_SetChannelBufferSize): Lowest size limit
+ * tests/io.test: changed from ten bytes to one byte. Need for
+ * tests/iogt.test: this change was proven by Ross Cartlidge
+ <rossc@cisco.com> where [read stdin 1] was grabbing 10 bytes followed
+ by starting a child process that was intended to continue reading from

+
+2005-04-13 Don Porter <dgp@users.sourceforge.net>
+
+ * unix/tclUnixInit.c (TclpGetEncodingNameFromEnvironment): Reversed
+ order of verifying candidate [encoding system] value, checking against

+ scanning through the filesystem. Also ordered the table so that a
+ binary search could be used within it. Improves startup time a bit more
+ on some systems.

+ * generic/tclInterp.c: Corrected bad syntax of Tcl_Panic() call.

+ * generic/tclUtil.c (TclGetProcessGlobalValue): More robust handling
+ of bad TclInitProcessGlobalValueProc behavior; an immediate panic
+ rather than a mysterious crash later.
+
+ * generic/tclEncoding.c: Several changes to the way the
+ encodingFileMap cache is maintained. Previously, it was attempted to
+ keep the file map filled and up to date with changes in the encoding
+ search path. This contributed to slow startup times since it required
+ an expensive "glob" operation to fill the cache. Now the validity of
+ items in the cache are checked at the time they are used, so the cache
+ is permitted to fall out of sync with the encoding search path. Only
+ [encoding names] and Tcl_GetEncodingNames() now pay the full expense.

+Changes to 8.5a1 include all changes to the 8.4 line through 8.4.6,
+plus the following, which focuses on the high-level feature changes
+in this changeset (new minor version) rather than bug fixes:
+
+ * refactored IO code to split FS path code into generic/tclPathObj.c
+ and generic/tclFileSystem.h
+
+ * refactored trace code into generic/tclTrace.c
+
+ * configure scripts now require autoconf 2.57 for regeneration
+
+ * updated runtime library scripts to use newer Tcl code features
+ (like replacing regsub with string map)
+
+ * improve robustness of tcltest test suite across environments
+
+ * changed the bytecode evaluation-stack addressing mode, from array-style
+ to pointer-style; the catch stack and evaluation stack are now
+ contiguous in memory
+
+ * switch command is now byte-compiled
+
+ * enhanced checking in 'file' command for Windows NT file permissions
+
+ * [TIP #57] new 'lassign' command (adopted from TclX)
+
+ * [TIP #75] switch -regexp now provides submatch info
+
+ * [TIP #90] extended 'catch' and 'return' to enable creation of procs
+ that are a true replacement for 'return'
+
+ * [TIP #100] new 'unload' command (can unload DLLs loaded via 'load',
+ requires the extension writer to support it)
+
+ * [TIP #111] new 'dict' command. Several commands have been updated
+ to handle the list form of dicts implicitly at the C level where
+ only lists were previously accepted
+
+ * [TIP #112] 'namespace ensemble' command addition allows for ensembles
+ that build on the namespace abstraction
+
+ * [TIP #118] file attributes -readonly option for unices that support
+ chflags(), support Mac Classic attribute options on OS X, add
+ -rsrclength for OS X, enhance file copy on OS X to copy finder
+ attributes and resource forks transparently
+
+ * [TIP #120] enable dde in safe interpreters
+ * [TIP #130] enable unique dde server names on Windows
+ * [TIP #135] change dde servername -exact option to -force
+=> dde 1.3
+
+ * [TIP #121] new Tcl_SetExitProc C API to control application shutdown
+
+ * [TIP #123] expr ** exponentiation operator
+
+ * [TIP #124] 'clock clicks -milliseconds' now returns a wide integer and a
+ new 'clock clicks -microseconds' returns a wide integer, representing
+ the number of microseconds, both since the Posix epoch
+
+ * [TIP #127] added 'lsearch -index' option
+
+ * [TIP #136] added 'lrepeat' command
+
+ * [TIP #137/151] Add -encoding option to 'source' command and main tclsh
+ executable.
+ *** POTENTIAL INCOMPATIBILITY ***
+ For Tcl embedders that build on Tcl_Main() and make use of Tcl_Main's
+ former ability to pass a leading "-encoding" option to interactive shell
+ operations, this will now be consumed by Tcl.
+
+ * [TIP #138] New TCL_HASH_KEY_SYSTEM_HASH option for Tcl hash tables
+
+ * [TIP #139] documented portions of Tcl's namespace C APIs
+
+ * [TIP #148] correct [list]-quoting of the '#' character
+ *** POTENTIAL INCOMPATIBILITY ***
+ For scripts that assume a particular (buggy) string rep for lists.
+
+ * [TIP #156] add "root locale" to msgcat
+=> msgcat 1.4
+
+ * [TIP #157] leading {expand} syntax on words to cause argument expansion.
+ This is a safer/cleaner alternative to the use of 'eval'.

-The variable \fBerrorInfo\fR holds a stack trace of the
+.VS 8.5
+The \fBTcl_SetReturnOptions\fR and \fBTcl_GetReturnOptions\fR
+routines expose the same capabilities as the \fBreturn\fR and
+\fBcatch\fR commands, respectively, in the form of a C interface.
+.PP
+\fBTcl_GetReturnOptions\fR retrieves the dictionary of return options
+from an interpreter following a script evaluation.
+Routines such as \fBTcl_Eval\fR are called to evaluate a
+script in an interpreter. These routines return an integer
+completion code. These routines also leave in the interpreter
+both a result and a dictionary of return options generated
+by script evaluation. Just as \fBTcl_GetObjResult\fR retrieves
+the result, \fBTcl_GetReturnOptions\fR retrieves the dictionary
+of return options. The integer completion code should be
+passed as the \fIcode\fR argument to \fBTcl_GetReturnOptions\fR
+so that all required options will be present in the dictionary.
+Specifically, a \fIcode\fR value of \fBTCL_ERROR\fR will
+ensure that entries for the keys \fB\-errorinfo\fR,
+\fB\-errorcode\fR, and \fB\-errorline\fR will appear in the
+dictionary. Also, the entries for the keys \fB\-code\fR
+and \fB\-level\fR will be adjusted if necessary to agree
+with the value of \fIcode\fR. The \fB(Tcl_Obj *)\fR returned
+by \fBTcl_GetReturnOptions\fR points to an unshared
+\fBTcl_Obj\fR with reference count of zero. The dictionary
+may be written to, either adding, removing, or overwriting
+any entries in it, with the need to check for a shared object.
+.PP
+A typical usage for \fBTcl_GetReturnOptions\fR is to
+retrieve the stack trace when script evaluation returns
+\fBTCL_ERROR\fR, like so:
+.CS
+int code = Tcl_Eval(interp, script);
+if (code == TCL_ERROR) {
+ Tcl_Obj *options = Tcl_GetReturnOptions(interp, code);
+ Tcl_Obj *key = Tcl_NewStringObj("-errorinfo", -1);
+ Tcl_Obj *stackTrace;
+ Tcl_IncrRefCount(key);
+ Tcl_DictObjGet(NULL, options, key, &stackTrace);
+ Tcl_DecrRefCount(key);
+ /* Do something with stackTrace */
+}
+.CE
+.PP
+\fBTcl_SetReturnOptions\fR sets the return options
+of \fIinterp\fR to be \fIoptions\fR. If \fIoptions\fR
+contains any invalid value for any key, TCL_ERROR will
+be returned, and the interp result will be set to an
+appropriate error message. Otherwise, a completion code
+in agreement with the \fB\-code\fR and \fB\-level\fR
+keys in \fIoptions\fR will be returned.
+.PP
+As an example, Tcl's \fBreturn\fR command itself could
+be implemented in terms of \fBTcl_SetReturnOptions\fR
+like so:
+.CS
+if ((objc % 2) == 0) { /* explicit result argument */
+ objc--;
+ Tcl_SetObjResult(interp, objv[objc]);
+}
+return Tcl_SetReturnOptions(interp, Tcl_NewListObj(objc-1, objv+1));
+.CE
+(It is not really implemented that way. Internal access
+privileges allow for a more efficient alternative that meshes
+better with the bytecode compiler.)
+.PP
+Note that a newly created \fBTcl_Obj\fR may be passed
+in as the \fIoptions\fR argument without the need to tend
+to any reference counting. This is analogous to
+\fBTcl_SetObjResult\fR.
+.PP
+While \fBTcl_SetReturnOptions\fR provides a general interface
+to set any collection of return options, there are a handful
+of return options that are very frequently used. Most
+notably the \fB\-errorinfo\fR and \fB\-errorcode\fR return
+options should be set properly when the command procedure
+of a command returns \fBTCL_ERROR\fR. Tcl provides several
+simpler interfaces to more directly set these return options.
+.VE 8.5

+The \fB\-errorinfo\fR option holds a stack trace of the
operations that were in progress when an error occurred,
and is intended to be human-readable.

command that was being executed when the error occurred.
By the time the error has been passed all the way back
to the application, it will contain a complete trace
of the activity in progress when the error occurred.
.PP
It is sometimes useful to add additional information to
-\fBerrorInfo\fR beyond what can be supplied automatically
-by \fBTcl_EvalObjEx\fR.
-\fBTcl_AddObjErrorInfo\fR may be used for this purpose:
-its \fImessage\fR and \fIlength\fR arguments describe an additional
-string to be appended to \fBerrorInfo\fR.
-For example, the \fBsource\fR command calls \fBTcl_AddObjErrorInfo\fR

+For example, when an error arises during the \fBsource\fR command,

+record the name of the file being processed and the
+line number on which the error occurred.
+Likewise, when an error arises during evaluation of a
+Tcl procedures, the procedure name and line number
within the procedure are recorded, and so on.

+\fBTcl_AppendObjToErrorInfo\fR is an alternative interface to the

+\fBTcl_AddObjErrorInfo\fR is nearly identical
+to \fBTcl_AddErrorInfo\fR, except that it has an additional \fIlength\fR

+If the \fImessage\fR needs to contain the null character \fBU+0000\fR,

-Otherwise, \fBTcl_GetBooleanFromObj\fR returns \fBTCL_OK\fR

+.SH DESCRIPTION
+.PP
+Tcl dictionary objects have an internal representation that supports
+efficient mapping from keys to values and which guarantees that the
+particular ordering of keys within the dictionary remains the same
+modulo any keys being deleted (which removes them from the order) or
+added (which adds them to the end of the order). If reinterpreted as a
+list, the values at the even-valued indices in the list will be the
+keys of the dictionary, and each will be followed (in the odd-valued
+index) by the value associated with that key.
+.PP
+The procedures described in this man page are used to
+create, modify, index, and iterate over dictionary objects from C code.
+.PP
+\fBTcl_NewDictObj\fR creates a new, empty dictionary object. The
+string representation of the object will be invalid, and the reference
+count of the object will be zero.
+.PP
+\fBTcl_DictObjGet\fR looks up the given key within the given
+dictionary and writes a pointer to the value associated with that key
+into the variable pointed to by \fIvaluePtrPtr\fR, or a NULL if the
+key has no mapping within the dictionary. The result of this
+procedure is \fBTCL_OK\fR, or \fBTCL_ERROR\fR if the \fIdictPtr\fR cannot be
+converted to a dictionary.
+.PP
+\fBTcl_DictObjPut\fR updates the given dictionary so that the given
+key maps to the given value; any key may exist at most once in any
+particular dictionary. The dictionary must not be shared, but the key
+and value may be. This procedure may increase the reference count of
+both key and value if it proves necessary to store them. Neither key
+nor value should be NULL. The result of this procedure is \fBTCL_OK\fR, or
+\fBTCL_ERROR\fR if the \fIdictPtr\fR cannot be converted to a dictionary.
+.PP
+\fBTcl_DictObjRemove\fR updates the given dictionary so that the given
+key has no mapping to any value. The dictionary must not be shared,
+but the key may be. The key actually stored in the dictionary will
+have its reference count decremented if it was present. It is not an
+error if the key did not previously exist. The result of this
+procedure is \fBTCL_OK\fR, or \fBTCL_ERROR\fR if the \fIdictPtr\fR cannot be
+converted to a dictionary.
+.PP
+\fBTcl_DictObjSize\fR updates the given variable with the number of
+key/value pairs currently in the given dictionary. The result of this
+procedure is \fBTCL_OK\fR, or \fBTCL_ERROR\fR if the \fIdictPtr\fR cannot be
+converted to a dictionary.
+.PP
+\fBTcl_DictObjFirst\fR commences an iteration across all the key/value
+pairs in the given dictionary, placing the key and value in the
+variables pointed to by the \fIkeyPtrPtr\fR and \fIvaluePtrPtr\fR
+arguments (which may be NULL to indicate that the caller is
+uninterested in they key or variable respectively.) The next
+key/value pair in the dictionary may be retrieved with
+\fBTcl_DictObjNext\fR. Concurrent updates of the dictionary's
+internal representation will not modify the iteration processing
+unless the dictionary is unshared, when this will trigger premature
+termination of the iteration instead (which Tcl scripts cannot trigger
+via the \fBdict\fR command.) The \fIsearchPtr\fR argument points to a
+piece of context that is used to identify which particular iteration
+is being performed, and is initialized by the call to
+\fBTcl_DictObjFirst\fR. The \fIdonePtr\fR argument points to a
+variable that is updated to be zero of there are further key/value
+pairs to be iterated over, or non-zero if the iteration is complete.
+The order of iteration is implementation-defined. If the
+\fIdictPtr\fR argument cannot be converted to a dictionary,
+\fBTcl_DictObjFirst\fR returns \fBTCL_ERROR\fR and the iteration is not
+commenced, and otherwise it returns \fBTCL_OK\fR.
+.PP
+When \fBTcl_DictObjFirst\fR is called upon a dictionary, a lock is placed on
+the dictionary to enable that dictionary to be iterated over safely without
+regard for whether the dictionary is modified during the iteration. Because of
+this, once the iteration over a dictionary's keys has finished (whether
+because all values have been iterated over as indicated by the variable
+indicated by the \fIdonePtr\fR argument being set to one, or because no
+further values are required) the \fBTcl_DictObjDone\fR function must be called
+with the same \fIsearchPtr\fR as was passed to \fBTcl_DictObjFirst\fR so that
+the internal locks can be released. Once a particular \fIsearchPtr\fR is
+passed to \fBTcl_DictObjDone\fR, passing it to \fBTcl_DictObjNext\fR (without
+first initializing it with \fBTcl_DictObjFirst\fR) will result in no values
+being produced and the variable pointed to by \fIdonePtr\fR being set to one.
+It is safe to call \fBTcl_DictObjDone\fR multiple times on the same
+\fIsearchPtr\fR for each call to \fBTcl_DictObjFirst\fR.
+.PP
+The procedures \fBTcl_DictObjPutKeyList\fR and
+\fBTcl_DictObjRemoveKeyList\fR are the close analogues of
+\fBTcl_DictObjPut\fR and \fBTcl_DictObjRemove\fR respectively, except
+that instead of working with a single dictionary, they are designed to
+operate on a nested tree of dictionaries, with inner dictionaries
+stored as values inside outer dictionaries. The \fIkeyc\fR and
+\fIkeyv\fR arguments specify a list of keys (with outermost keys
+first) that acts as a path to the key/value pair to be affected. Note
+that there is no corresponding operation for reading a value for a
+path as this is easy to construct from repeated use of
+\fBTcl_DictObjGet\fR. With \fBTcl_DictObjPutKeyList\fR, nested
+dictionaries are created for non-terminal keys where they do not
+already exist. With \fBTcl_DictObjRemoveKeyList\fR, all non-terminal
+keys must exist and have dictionaries as their values.

+is a key that maps to itself:
+.PP

+Tcl_DictSearch search;
+Tcl_Obj *key, *value;

+ * be released manually when an exceptional exit from the loop
+ * is performed. However it is safe to try to release the lock
+ * even if we've finished iterating over the loop.

-\fBTcl_SetDoubleObj\fR invalidates any old string representation
-and, if the object is not already a double object,

-\fBTcl_GetDoubleFromObj\fR attempts to return a double value
-from the Tcl object \fIobjPtr\fR.
-If the object is not already a double object,

-If an error occurs during conversion, it returns \fBTCL_ERROR\fR

+\fBTcl_NewDoubleObj\fR creates and returns a new Tcl object initialized to
+the double value \fIdoubleValue\fR. The returned Tcl object is unshared.
+.PP
+\fBTcl_SetDoubleObj\fR sets the value of an existing Tcl object pointed to
+by \fIobjPtr\fR to the double value \fIdoubleValue\fR. The \fIobjPtr\fR
+argument must point to an unshared Tcl object. Any attempt to set the value
+of a shared Tcl object violates Tcl's copy-on-write policy. Any existing
+string representation or internal representation in the unshared Tcl object
+will be freed as a consequence of setting the new value.
+.PP
+\fBTcl_GetDoubleFromObj\fR attempts to retrieve a double value from the
+Tcl object \fIobjPtr\fR. If the attempt succeeds, then \fBTCL_OK\fR is
+returned, and the double value is written to the storage pointed to by

+.SH DESCRIPTION
+An ensemble is a command, bound to some namespace, which consists of a
+collection of subcommands implemented by other Tcl commands. The first
+argument to the ensemble command is always interpreted as a selector
+that states what subcommand to execute.
+.PP
+Ensembles are created using \fBTcl_CreateEnsemble\fR, which takes four
+arguments: the interpreter to work within, the name of the ensemble to
+create, the namespace within the interpreter to bind the ensemble to,
+and the default set of ensemble flags. The result of the function is
+the command token for the ensemble, which may be used to further
+configure the ensemble using the API described below in \fBENSEMBLE
+PROPERTIES\fR.
+.PP
+Given the name of an ensemble command, the token for that command may
+be retrieved using \fBTcl_FindEnsemble\fR. If the given command name
+(in \fIcmdNameObj\fR) does not refer to an ensemble command, the
+result of the function is NULL and (if the TCL_LEAVE_ERR_MSG bit is
+set in \fIflags\fR) an error message is left in the interpreter
+result.
+.PP
+A command token may be checked to see if it refers to an ensemble
+using \fBTcl_IsEnsemble\fR. This returns 1 if the token refers to an
+ensemble, or 0 otherwise.
+.SS "ENSEMBLE PROPERTIES"
+Every ensemble has four read-write properties and a read-only
+property. The properties are:
+.TP
+\fBflags\fR (read-write)
+The set of flags for the ensemble, expressed as a
+bit-field. Currently, the only public flag is TCL_ENSEMBLE_PREFIX
+which is set when unambiguous prefixes of subcommands are permitted to
+be resolved to implementations as well as exact matches. The flags may
+be read and written using \fBTcl_GetEnsembleFlags\fR and
+\fBTcl_SetEnsembleFlags\fR respectively. The result of both of those
+functions is a Tcl result code (TCL_OK, or TCL_ERROR if the token does
+not refer to an ensemble).
+.TP
+\fBmapping dictionary\fR (read-write)
+A dictionary containing a mapping from subcommand names to lists of
+words to use as a command prefix (replacing the first two words of the
+command which are the ensemble command itself and the subcommand
+name), or NULL if every subcommand is to be mapped to the command with
+the same unqualified name in the ensemble's bound namespace. Defaults
+to NULL. May be read and written using
+\fBTcl_GetEnsembleMappingDict\fR and \fBTcl_SetEnsembleMappingDict\fR
+respectively. The result of both of those functions is a Tcl result
+code (TCL_OK, or TCL_ERROR if the token does not refer to an
+ensemble) and the dictionary obtained from
+\fBTcl_GetEnsembleMappingDict\fR should always be treated as immutable
+even if it is unshared.
+.TP
+\fBsubcommand list\fR (read-write)
+A list of all the subcommand names for the ensemble, or NULL if this
+is to be derived from either the keys of the mapping dictionary (see
+above) or (if that is also NULL) from the set of commands exported by
+the bound namespace. May be read and written using
+\fBTcl_GetEnsembleSubcommandList\fR and
+\fBTcl_SetEnsembleSubcommandList\fR respectively. The result of both
+of those functions is a Tcl result code (TCL_OK, or TCL_ERROR if the
+token does not refer to an ensemble) and the list obtained from
+\fBTcl_GetEnsembleSubcommandList\fR should always be treated as
+immutable even if it is unshared.
+.TP
+\fBunknown subcommand handler command prefix\fR (read-write)
+A list of words to prepend on the front of any subcommand when the
+subcommand is unknown to the ensemble (according to the current prefix
+handling rule); see the \fBnamespace ensemble\fR command for more
+details. If NULL, the default behavior \- generate a suitable error
+message \- will be used when an unknown subcommand is encountered. May
+be read and written using \fBTcl_GetEnsembleUnknownHandler\fR and
+\fBTcl_SetEnsembleUnknownHandler\fR respectively. The result of both
+functions is a Tcl result code (TCL_OK, or TCL_ERROR if the token does
+not refer to an ensemble) and the list obtained from
+\fBTcl_GetEnsembleUnknownHandler\fR should always be treated as
+immutable even if it is unshared.
+.TP
+\fBbound namespace\fR (read-only)
+The namespace to which the ensemble is bound; when the namespace is
+deleted, so too will the ensemble, and this namespace is also the
+namespace whose list of exported commands is used if both the mapping
+dictionary and the subcommand list properties are NULL. May be read
+using \fBTcl_GetEnsembleNamespace\fR which returns a Tcl result code
+(TCL_OK, or TCL_ERROR if the token does not refer to an ensemble).

(On single-processor Windows systems, the \fIusec\fR field is derived
from a performance counter and is highly precise.)
+.PP
+The \fBTcl_SetTime\fR function registers two related handler functions
+with the core. The first handler function is a replacement for
+\fBTcl_GetTime\fR, or rather the OS access made by
+\fBTcl_GetTime\fR. The other handler function is used by the Tcl
+notifier to convert wait/block times from the virtual domain into real
+time.
+.PP
+The \fBTcl_QueryTime\fR function returns the currently registered
+handler functions. If no external handlers were set then this will
+return the standard handlers accessing and processing the native time
+of the OS. The arguments to the function are allowed to be NULL; and
+any argument which is NULL is ignored and not set.
+.PP
+Any handler pair specified has to return data which is consistent
+between them. In other words, setting one handler of the pair to
+something assuming a 10-times slowdown, and the other handler of the
+pair to something assuming a two-times slowdown is wrong and not
+allowed.
+.PP
+The set handler functions are allowed to run the delivered time
+backwards, however this should be avoided. We have to allow it as the
+native time can run backwards as the user can fiddle with the system
+time one way or other. Note that the insertion of the hooks will not
+change the behaviour of the Tcl core with regard to this situation,
+i.e. the existing behaviour is retained.

+The different routines exist to accommodate different integral types in C
+with which values might be exchanged. The C integral types for which Tcl
+provides value exchange routines are \fBint\fR, \fBlong int\fR,
+\fBTcl_WideInt\fR, and \fBmp_int\fR. The \fBint\fR and \fBlong int\fR types
+are provided by the C language standard. The \fBTcl_WideInt\fR type is a
+typedef defined to be whatever signed integral type covers at least the
+64-bit integer range (-9223372036854775808 to 9223372036854775807). Depending
+on the platform and the C compiler, the actual type might be
+\fBlong int\fR, \fBlong long int\fR, \fBint64\fR, or something else.

+.SH DESCRIPTION
+.PP
+Tcl's interpreter resource limit subsystem allows for close control
+over how much computation time a script may use, and is useful for
+cases where a program is divided into multiple pieces where some parts
+are more trusted than others (e.g. web application servers).
+.PP
+Every interpreter may have a limit on the wall-time for execution, and
+a limit on the number of commands that the interpreter may execute.
+Since checking of these limits is potentially expensive (especially
+the time limit), each limit also has a checking granularity, which is
+a divisor for an internal count of the number of points in the core
+where a check may be performed (which is immediately before executing
+a command and at an unspecified frequency between running commands,
+which can happen in empty-bodied \fBwhile\fR loops).
+.PP
+The final component of the limit engine is a callback scheme which
+allows for notifications of when a limit has been exceeded. These
+callbacks can just provide logging, or may allocate more resources to
+the interpreter to permit it to continue processing longer.
+.PP
+When a limit is exceeded (and the callbacks have run; the order of
+execution of the callbacks is unspecified) execution in the limited
+interpreter is stopped by raising an error and setting a flag that
+prevents the \fBcatch\fR command in that interpreter from trapping
+that error. It is up to the context that started execution in that
+interpreter (typically a master interpreter) to handle the error.
+.SH "LIMIT CHECKING API"
+.PP
+To check the resource limits for an interpreter, call
+\fBTcl_LimitCheck\fR, which returns \fBTCL_OK\fR if the limit was not
+exceeded (after processing callbacks) and \fBTCL_ERROR\fR if the limit was
+exceeded (in which case an error message is also placed in the
+interpreter result). That function should only be called when
+\fBTcl_LimitReady\fR returns non-zero so that granularity policy is
+enforced. This API is designed to be similar in usage to
+\fBTcl_AsyncReady\fR and \fBTcl_AsyncInvoke\fR.
+.PP
+When writing code that may behave like \fBcatch\fR in respect of
+errors, you should only trap an error if \fBTcl_LimitExceeded\fR
+returns zero. If it returns non-zero, the interpreter is in a
+limit-exceeded state and errors should be allowed to propagate to the
+calling context. You can also check whether a particular type of
+limit has been exceeded using \fBTcl_LimitTypeExceeded\fR.
+.SH "LIMIT CONFIGURATION"
+.PP
+To check whether a limit has been set (but not whether it has actually
+been exceeded) on an interpreter, call \fBTcl_LimitTypeEnabled\fR with
+the type of limit you want to check. To enable a particular limit
+call \fBTcl_LimitTypeSet\fR, and to disable a limit call
+\fBTcl_LimitTypeReset\fR.
+.PP
+The level of a command limit may be set using
+\fBTcl_LimitSetCommands\fR, and retrieved using
+\fBTcl_LimitGetCommands\fR. Similarly for a time limit with
+\fBTcl_LimitSetTime\fR and \fBTcl_LimitGetTime\fR respectively, but
+with that API the time limit is copied from and to the Tcl_Time
+structure that the \fItimeLimitPtr\fR argument points to.
+.PP
+The checking granularity for a particular limit may be set using
+\fBTcl_LimitSetGranularity\fR and retrieved using
+\fBTcl_LimitGetGranularity\fR. Note that granularities must always be
+positive.
+.SS "LIMIT CALLBACKS"
+.PP
+To add a handler callback to be invoked when a limit is exceeded, call
+\fBTcl_LimitAddHandler\fR. The \fIhandlerProc\fR argument describes
+the function that will actually be called; it should have the
+following prototype:
+.PP
+.CS
+typedef void Tcl_LimitHandlerProc(
+ ClientData \fIclientData\fR,
+ Tcl_Interp *\fIinterp\fR);
+.CE
+.PP
+The \fIclientData\fR argument to the handler will be whatever is
+passed to the \fIclientData\fR argument to \fBTcl_LimitAddHandler\fR,
+and the \fIinterp\fR is the interpreter that had its limit exceeded.
+.PP
+The \fIdeleteProc\fR argument to \fBTcl_LimitAddHandler\fR is a
+function to call to delete the \fIclientData\fR value. It may be
+\fBTCL_STATIC\fR or NULL if no deletion action is necessary, or
+\fBTCL_DYNAMIC\fR if all that is necessary is to free the structure with
+\fBTcl_Free\fR. Otherwise, it should refer to a function with the
+following prototype:
+.PP
+.CS
+typedef void Tcl_LimitHandlerDeleteProc(
+ ClientData \fIclientData\fR);
+.CE
+.PP
+A limit handler may be deleted using \fBTcl_LimitRemoveHandler\fR; the
+handler removed will be the first one found (out of the handlers added
+with \fBTcl_LimitAddHandler\fR) with exactly matching \fItype\fR,
+\fIhandlerProc\fR and \fIclientData\fR arguments. This function
+always invokes the \fIdeleteProc\fR on the \fIclientData\fR (unless
+the \fIdeleteProc\fR was NULL or \fBTCL_STATIC\fR).

-.PP
-The described routines are used to implement the Macintosh specific

-
-.SH DESCRIPTION
-.PP
-\fBTcl_MacEvalResource\fR extends the \fBsource\fR command to
-Macintosh resources. It sources Tcl code from a Text resource.
-Currently only sources the resource by name, file IDs may be supported
-at a later date.
-.PP
-\fBTcl_MacConvertTextResource\fR converts a TEXT resource into a Tcl
-suitable string. It mallocs the returned memory, converts ``\\r'' to
-``\\n'', and appends a null. The caller has the responsibility for
-freeing the memory.
-.PP
-\fBTcl_MacFindResource\fR provides a higher level interface for
-loading resources. It is used by \fBresource read\fR.
-.PP
-\fBTcl_NewOSTypeObj\fR is used to create a new resource name type
-object. The object type is "ostype".
-.PP
-\fBTcl_SetOSTypeObj\fR modifies an object to be a resource type and to
-have the specified long value.
-.PP
-\fBTcl_GetOSTypeFromObj\fR attempts to return an int from the Tcl
-object "objPtr". If the object is not already an int, an attempt will
-be made to convert it to one.
-.PP
-\fBTcl_MacSetEventProc\fR sets the event handling procedure for the
-application. This function will be passed all incoming Mac events.
-This function usually controls the console or some other entity like
-Tk.
-
-.SH RESOURCE TYPES
-.PP
-Resource types are 4-byte values used by the macintosh resource
-facility to tag parts of the resource fork in a file so that the OS
-knows how to handle them. As all 4 bytes are restricted to printable
-characters such a type can be interpreted as a 4 character string too.

+.PP
+Namespaces are hierarchic naming contexts that can contain commands
+and variables. They also maintain a list of patterns that describes
+what commands are exported, and can import commands that have been
+exported by other namespaces. Namespaces can also be manipulated
+through the Tcl command \fBnamespace\fR.
+.PP
+The \fITcl_Namespace\fR structure encapsulates a namespace, and is
+guaranteed to have the following fields in it: \fIname\fR (the local
+name of the namespace, with no namespace separator characters in it,
+with empty denoting the global namespace), \fIfullName\fR (the fully
+specified name of the namespace), \fIclientData\fR, \fIdeleteProc\fR
+(the values specified in the call to \fBTcl_CreateNamespace\fR), and
+\fIparentPtr\fR (a pointer to the containing namespace, or NULL for
+the global namespace.)
+.PP
+\fBTcl_CreateNamespace\fR creates a new namespace. The
+\fIdeleteProc\fR will have the following type signature:
+.CS
+typedef void (Tcl_NamespaceDeleteProc) (ClientData clientData);
+.CE
+.PP
+\fBTcl_DeleteNamespace\fR deletes a namespace.
+.PP
+\fBTcl_AppendExportList\fR retrieves the export patterns for a
+namespace given namespace and appends them (as list items) to
+\fIobjPtr\fR.
+.PP
+\fBTcl_Export\fR sets and appends to the export patterns for a
+namespace. Patterns are appended unless the \fIresetListFirst\fR flag
+is true.
+.PP
+\fBTcl_Import\fR imports commands matching a pattern into a
+namespace. Note that the pattern must include the name of the
+namespace to import from. This function returns an error if
+an attempt to import a command over an existing command is made,
+unless the \fIallowOverwrite\fR flag has been set.
+.PP
+\fBTcl_ForgetImport\fR removes imports matching a pattern.
+.PP
+\fBTcl_GetCurrentNamespace\fR returns the current namespace for an
+interpreter.
+.PP
+\fBTcl_GetGlobalNamespace\fR returns the global namespace for an
+interpreter.
+.PP
+\fBTcl_FindNamespace\fR searches for a namespace named \fIname\fR
+within the context of the namespace \fIcontextNsPtr\fR. If the
+namespace cannot be found, NULL is returned.
+.PP
+\fBTcl_FindCommand\fR searches for a command named \fIname\fR within
+the context of the namespace \fIcontextNsPtr\fR. If the command
+cannot be found, NULL is returned.
+.PP
+\fBTcl_GetNamespaceUnknownHandler\fR returns the unknown command handler
+for the namespace, or NULL if none is set.
+.PP
+\fBTcl_SetNamespaceUnknownHandler\fR sets the unknown command handler for
+the namespace. If \fIhandlerPtr\fR is NULL, then the handler is reset to
+its default.

Storage for the byte array must be allocated in the heap by \fBTcl_Alloc\fR

-For example, Tcl list objects have an \fIinternalRep.otherValuePtr\fR

+.SH DESCRIPTION
+.PP
+The function described here has its base in TIP 59 and provides
+extensions with support for the embedding of configuration
+information into their binary library and the generation of a
+Tcl-level interface for querying this information.
+.PP
+To embed configuration information into their binary library an
+extension has to define a non-volatile array of Tcl_Config entries in
+one if its source files and then call \fBTcl_RegisterConfig\fR to
+register that information.
+.PP
+\fBTcl_RegisterConfig\fR takes four arguments; first, a reference to
+the interpreter we are registering the information with, second, the
+name of the package registering its configuration information, third,
+a pointer to an array of structures, and fourth a string declaring the
+encoding used by the configuration values.
+.PP
+The string \fIvalEncoding\fR contains the name of an encoding known to
+Tcl. All these names are use only characters in the ASCII subset of
+UTF-8 and are thus implicitly in the UTF-8 encoding. It is expected
+that keys are legible English text and therefore using the ASCII
+subset of UTF-8. In other words, they are expected to be in UTF-8
+too. The values associated with the keys can be any string
+however. For these the contents of \fIvalEncoding\fR define which
+encoding was used to represent the characters of the strings.
+.PP
+Each element of the \fIconfiguration\fR array refers to two strings
+containing the key and the value associated with that key. The end of
+the array is signaled by either an empty key or a key identical to
+NULL. The function makes \fBno\fR copy of the \fIconfiguration\fR
+array. This means that the caller has to make sure that the memory
+holding this array is never released. This is the meaning behind the
+word \fBnon-volatile\fR used earlier. The easiest way to accomplish
+this is to define a global static array of Tcl_Config entries. See the file
+.QW generic/tclPkgConfig.c
+in the sources of the Tcl core for an example.
+.PP
+When called \fBTcl_RegisterConfig\fR will
+.IP (1)
+create a namespace having the provided \fIpkgName\fR, if not yet
+existing.
+.IP (2)
+create the command \fBpkgconfig\fR in that namespace and link it to
+the provided information so that the keys from _configuration_ and
+their associated values can be retrieved through calls to
+\fBpkgconfig\fR.
+.PP
+The command \fBpkgconfig\fR will provide two subcommands, \fBlist\fR
+and \fBget\fR:
+.RS
+.TP
+::\fIpkgName\fR::\fBpkgconfig\fR list
+Returns a list containing the names of all defined keys.

+.SH DESCRIPTION
+.PP
+The current definition of a Tcl channel driver does not permit the
+direct return of arbitrary error messages, except for the setting and
+retrieval of channel options. All other functions are restricted to
+POSIX error codes.
+.PP
+The functions described here overcome this limitation. Channel drivers
+are allowed to use \fBTcl_SetChannelError\fR and
+\fBTcl_SetChannelErrorInterp\fR to place arbitrary error messages in
+\fBbypass areas\fI defined for channels and interpreters. And the
+generic I/O layer uses \fBTcl_GetChannelError\fR and
+\fBTcl_GetChannelErrorInterp\fR to look for messages in the bypass
+areas and arrange for their return as errors. The posix error codes
+set by a driver are used now if and only if no messages are present.
+.PP
+\fBTcl_SetChannelError\fR stores error information in the bypass area
+of the specified channel. The number of references to the \fBmsg\fR
+object goes up by one. Previously stored information will be
+discarded, by releasing the reference held by the channel. The channel
+reference must not be NULL.
+.PP
+\fBTcl_SetChannelErrorInterp\fR stores error information in the bypass
+area of the specified interpreter. The number of references to the
+\fBmsg\fR object goes up by one. Previously stored information will be
+discarded, by releasing the reference held by the interpreter. The
+interpreter reference must not be NULL.
+.PP
+\fBTcl_GetChannelError\fR places either the error message held in the
+bypass area of the specified channel into \fImsgPtr\fR, or NULL; and
+resets the bypass. I.e. after an invocation all following invocations
+will return NULL, until an intervening invocation of
+\fBTcl_SetChannelError\fR with a non-NULL message. The \fImsgPtr\fR
+must not be NULL. The reference count of the message is not touched.
+The reference previously held by the channel is now held by the caller
+of the function and it is its responsibility to release that reference
+when it is done with the object.
+.PP
+\fBTcl_GetChannelErrorInterp\fR places either the error message held
+in the bypass area of the specified interpreter into \fImsgPtr\fR, or
+NULL; and resets the bypass. I.e. after an invocation all following
+invocations will return NULL, until an intervening invocation of
+\fBTcl_SetChannelErrorInterp\fR with a non-NULL message. The
+\fImsgPtr\fR must not be NULL. The reference count of the message is
+not touched. The reference previously held by the interpreter is now

+.BE
+.SH DESCRIPTION
+.PP
+The command \fBapply\fR applies the function \fIfunc\fR to the arguments
+\fIarg1 arg2 ...\fR and returns the result.
+.PP
+The function \fIfunc\fR is a two element list \fI{args body}\fR or a three
+element list \fI{args body namespace}\fR (as if the
+\fBlist\fR command had been used).
+The first element \fIargs\fR specifies the formal arguments to
+\fIfunc\fR. The specification of the formal arguments \fIargs\fR
+is shared with the \fBproc\fR command, and is described in detail in the
+corresponding manual page.
+.PP
+The contents of \fIbody\fR are executed by the Tcl interpreter
+after the local variables corresponding to the formal arguments are given
+the values of the actual parameters \fIarg1 arg2 ...\fR.
+When \fIbody\fR is being executed, variable names normally refer to
+local variables, which are created automatically when referenced and
+deleted when \fBapply\fR returns. One local variable is automatically
+created for each of the function's arguments.
+Global variables can only be accessed by invoking
+the \fBglobal\fR command or the \fBupvar\fR command.
+Namespace variables can only be accessed by invoking
+the \fBvariable\fR command or the \fBupvar\fR command.
+.PP
+The invocation of \fBapply\fR adds a call frame to Tcl's evaluation stack
+(the stack of frames accessed via \fBuplevel\fR). The execution of \fIbody\fR
+proceeds in this call frame, in the namespace given by \fInamespace\fR or
+in the global namespace if none was specified. If given, \fInamespace\fR is

This command provides facilities for manipulating binary data. The
first form, \fBbinary format\fR, creates a binary string from normal
-Tcl values. For example, given the values 16 and 22, on a 32 bit
+Tcl values. For example, given the values 16 and 22, on a 32-bit
architecture, it might produce an 8-byte binary string consisting of
two 4-byte integers, one for each of the numbers. The second form of
the command, \fBbinary scan\fR, does the opposite: it extracts data
from a binary string and returns it as ordinary Tcl string values.

+This command provides several operations for reading from, writing to
+and otherwise manipulating open channels (such as have been created
+with the \fBopen\fR and \fBsocket\fR commands, or the default named
+channels \fBstdin\fR, \fBstdout\fR or \fBstderr\fR which correspond to
+the process's standard input, output and error streams respectively).
+\fIOption\fR indicates what to do with the channel; any unique
+abbreviation for \fIoption\fR is acceptable. Valid options are:
+.TP
+\fBchan blocked \fIchannelId\fR
+.
+This tests whether the last input operation on the channel called
+\fIchannelId\fR failed because it would have otherwise caused the
+process to block, and returns 1 if that was the case. It returns 0
+otherwise. Note that this only ever returns 1 when the channel has
+been configured to be non-blocking; all Tcl channels have blocking
+turned on by default.
+.TP
+\fBchan close \fIchannelId\fR
+.
+Close and destroy the channel called \fIchannelId\fR. Note that this
+deletes all existing file-events registered on the channel.
+.RS
+.PP
+As part of closing the channel, all buffered output is flushed to the
+channel's output device, any buffered input is discarded, the
+underlying operating system resource is closed and \fIchannelId\fR
+becomes unavailable for future use.
+.PP
+If the channel is blocking, the command does not return until all
+output is flushed. If the channel is nonblocking and there is
+unflushed output, the channel remains open and the command returns
+immediately; output will be flushed in the background and the channel
+will be closed when all the flushing is complete.
+.PP
+If \fIchannelId\fR is a blocking channel for a command pipeline then
+\fBchan close\fR waits for the child processes to complete.
+.PP
+If the channel is shared between interpreters, then \fBchan close\fR
+makes \fIchannelId\fR unavailable in the invoking interpreter but has
+no other effect until all of the sharing interpreters have closed the
+channel. When the last interpreter in which the channel is registered
+invokes \fBchan close\fR (or \fBclose\fR), the cleanup actions
+described above occur. See the \fBinterp\fR command for a description
+of channel sharing.
+.PP
+Channels are automatically closed when an interpreter is destroyed and
+when the process exits. Channels are switched to blocking mode, to
+ensure that all output is correctly flushed before the process exits.
+.PP
+The command returns an empty string, and may generate an error if
+an error occurs while flushing output. If a command in a command
+pipeline created with \fBopen\fR returns an error, \fBchan close\fR
+generates an error (similar to the \fBexec\fR command.)
+.RE
+.TP
+\fBchan configure \fIchannelId\fR ?\fIoptionName\fR? ?\fIvalue\fR? ?\fIoptionName value\fR?...
+.
+Query or set the configuration options of the channel named
+\fIchannelId\fR.
+.RS
+.PP
+If no \fIoptionName\fR or \fIvalue\fR arguments are supplied, the
+command returns a list containing alternating option names and values
+for the channel. If \fIoptionName\fR is supplied but no \fIvalue\fR
+then the command returns the current value of the given option. If
+one or more pairs of \fIoptionName\fR and \fIvalue\fR are supplied,
+the command sets each of the named options to the corresponding
+\fIvalue\fR; in this case the return value is an empty string.
+.PP
+The options described below are supported for all channels. In
+addition, each channel type may add options that only it supports. See
+the manual entry for the command that creates each type of channels
+for the options that that specific type of channel supports. For
+example, see the manual entry for the \fBsocket\fR command for its
+additional options.
+.TP
+\fB\-blocking\fR \fIboolean\fR
+.
+The \fB\-blocking\fR option determines whether I/O operations on the
+channel can cause the process to block indefinitely. The value of the
+option must be a proper boolean value. Channels are normally in
+blocking mode; if a channel is placed into nonblocking mode it will
+affect the operation of the \fBchan gets\fR, \fBchan read\fR, \fBchan
+puts\fR, \fBchan flush\fR, and \fBchan close\fR commands; see the
+documentation for those commands for details. For nonblocking mode to
+work correctly, the application must be using the Tcl event loop
+(e.g. by calling \fBTcl_DoOneEvent\fR or invoking the \fBvwait\fR
+command).
+.TP
+\fB\-buffering\fR \fInewValue\fR
+.
+If \fInewValue\fR is \fBfull\fR then the I/O system will buffer output
+until its internal buffer is full or until the \fBchan flush\fR
+command is invoked. If \fInewValue\fR is \fBline\fR, then the I/O
+system will automatically flush output for the channel whenever a
+newline character is output. If \fInewValue\fR is \fBnone\fR, the I/O
+system will flush automatically after every output operation. The
+default is for \fB\-buffering\fR to be set to \fBfull\fR except for
+channels that connect to terminal-like devices; for these channels the
+initial setting is \fBline\fR. Additionally, \fBstdin\fR and
+\fBstdout\fR are initially set to \fBline\fR, and \fBstderr\fR is set
+to \fBnone\fR.
+.TP
+\fB\-buffersize\fR \fInewSize\fR
+.
+\fINewvalue\fR must be an integer; its value is used to set the size
+of buffers, in bytes, subsequently allocated for this channel to store
+input or output. \fINewvalue\fR must be a number of no more than one
+million, allowing buffers of up to one million bytes in size.
+.TP
+\fB\-encoding\fR \fIname\fR
+.
+This option is used to specify the encoding of the channel as one of
+the named encodings returned by \fBencoding names\fR or the special
+value \fBbinary\fR, so that the data can be converted to and from
+Unicode for use in Tcl. For instance, in order for Tcl to read
+characters from a Japanese file in \fBshiftjis\fR and properly process
+and display the contents, the encoding would be set to \fBshiftjis\fR.
+Thereafter, when reading from the channel, the bytes in the Japanese
+file would be converted to Unicode as they are read. Writing is also
+supported \- as Tcl strings are written to the channel they will
+automatically be converted to the specified encoding on output.
+.RS
+.PP
+If a file contains pure binary data (for instance, a JPEG image), the
+encoding for the channel should be configured to be \fBbinary\fR. Tcl
+will then assign no interpretation to the data in the file and simply
+read or write raw bytes. The Tcl \fBbinary\fR command can be used to
+manipulate this byte-oriented data. It is usually better to set the
+\fB\-translation\fR option to \fBbinary\fR when you want to transfer
+binary data, as this turns off the other automatic interpretations of
+the bytes in the stream as well.
+.PP
+The default encoding for newly opened channels is the same platform-
+and locale-dependent system encoding used for interfacing with the
+operating system, as returned by \fBencoding system\fR.
+.RE
+.TP
+\fB\-eofchar\fR \fIchar\fR
+.TP
+\fB\-eofchar\fR \fB{\fIinChar outChar\fB}\fR
+.
+This option supports DOS file systems that use Control-z (\ex1a) as an
+end of file marker. If \fIchar\fR is not an empty string, then this
+character signals end-of-file when it is encountered during input.
+For output, the end-of-file character is output when the channel is
+closed. If \fIchar\fR is the empty string, then there is no special
+end of file character marker. For read-write channels, a two-element
+list specifies the end of file marker for input and output,
+respectively. As a convenience, when setting the end-of-file
+character for a read-write channel you can specify a single value that
+will apply to both reading and writing. When querying the end-of-file
+character of a read-write channel, a two-element list will always be
+returned. The default value for \fB\-eofchar\fR is the empty string
+in all cases except for files under Windows. In that case the
+\fB\-eofchar\fR is Control-z (\ex1a) for reading and the empty string
+for writing.
+The acceptable range for \fB\-eofchar\fR values is \ex01 - \ex7f;
+attempting to set \fB\-eofchar\fR to a value outside of this range will
+generate an error.
+.TP
+\fB\-translation\fR \fImode\fR
+.TP
+\fB\-translation\fR \fB{\fIinMode outMode\fB}\fR
+.
+In Tcl scripts the end of a line is always represented using a single
+newline character (\en). However, in actual files and devices the end
+of a line may be represented differently on different platforms, or
+even for different devices on the same platform. For example, under
+UNIX newlines are used in files, whereas carriage-return-linefeed
+sequences are normally used in network connections. On input (i.e.,
+with \fBchan gets\fR and \fBchan read\fR) the Tcl I/O system
+automatically translates the external end-of-line representation into
+newline characters. Upon output (i.e., with \fBchan puts\fR), the I/O
+system translates newlines to the external end-of-line representation.
+The default translation mode, \fBauto\fR, handles all the common cases
+automatically, but the \fB\-translation\fR option provides explicit
+control over the end of line translations.
+.RS
+.PP
+The value associated with \fB\-translation\fR is a single item for
+read-only and write-only channels. The value is a two-element list for
+read-write channels; the read translation mode is the first element of
+the list, and the write translation mode is the second element. As a
+convenience, when setting the translation mode for a read-write channel
+you can specify a single value that will apply to both reading and
+writing. When querying the translation mode of a read-write channel, a
+two-element list will always be returned. The following values are
+currently supported:
+.TP
+\fBauto\fR
+.
+As the input translation mode, \fBauto\fR treats any of newline
+(\fBlf\fR), carriage return (\fBcr\fR), or carriage return followed by
+a newline (\fBcrlf\fR) as the end of line representation. The end of
+line representation can even change from line-to-line, and all cases
+are translated to a newline. As the output translation mode,
+\fBauto\fR chooses a platform specific representation; for sockets on
+all platforms Tcl chooses \fBcrlf\fR, for all Unix flavors, it chooses
+\fBlf\fR, and for the various flavors of Windows it chooses
+\fBcrlf\fR. The default setting for \fB\-translation\fR is \fBauto\fR
+for both input and output.
+.TP
+\fBbinary\fR
+.
+No end-of-line translations are performed. This is nearly identical
+to \fBlf\fR mode, except that in addition \fBbinary\fR mode also sets
+the end-of-file character to the empty string (which disables it) and
+sets the encoding to \fBbinary\fR (which disables encoding filtering).
+See the description of \fB\-eofchar\fR and \fB\-encoding\fR for more
+information.
+.TP
+\fBcr\fR
+.
+The end of a line in the underlying file or device is represented by a
+single carriage return character. As the input translation mode,
+\fBcr\fR mode converts carriage returns to newline characters. As the
+output translation mode, \fBcr\fR mode translates newline characters
+to carriage returns.
+.TP
+\fBcrlf\fR
+.
+The end of a line in the underlying file or device is represented by a
+carriage return character followed by a linefeed character. As the
+input translation mode, \fBcrlf\fR mode converts
+carriage-return-linefeed sequences to newline characters. As the
+output translation mode, \fBcrlf\fR mode translates newline characters
+to carriage-return-linefeed sequences. This mode is typically used on
+Windows platforms and for network connections.
+.TP
+\fBlf\fR
+.
+The end of a line in the underlying file or device is represented by a
+single newline (linefeed) character. In this mode no translations
+occur during either input or output. This mode is typically used on
+UNIX platforms.

+\fBchan copy \fIinputChan outputChan\fR ?\fB\-size \fIsize\fR? ?\fB\-command \fIcallback\fR?
+.
+Copy data from the channel \fIinputChan\fR, which must have been
+opened for reading, to the channel \fIoutputChan\fR, which must have
+been opened for writing. The \fBchan copy\fR command leverages the
+buffering in the Tcl I/O system to avoid extra copies and to avoid
+buffering too much data in main memory when copying large files to
+slow destinations like network sockets.
+.RS
+.PP
+The \fBchan copy\fR command transfers data from \fIinputChan\fR until
+end of file or \fIsize\fR bytes have been transferred. If no
+\fB\-size\fR argument is given, then the copy goes until end of file.
+All the data read from \fIinputChan\fR is copied to \fIoutputChan\fR.
+Without the \fB\-command\fR option, \fBchan copy\fR blocks until the
+copy is complete and returns the number of bytes written to
+\fIoutputChan\fR.
+.PP
+The \fB\-command\fR argument makes \fBchan copy\fR work in the
+background. In this case it returns immediately and the
+\fIcallback\fR is invoked later when the copy completes. The
+\fIcallback\fR is called with one or two additional arguments that
+indicates how many bytes were written to \fIoutputChan\fR. If an
+error occurred during the background copy, the second argument is the
+error string associated with the error. With a background copy, it is
+not necessary to put \fIinputChan\fR or \fIoutputChan\fR into
+non-blocking mode; the \fBchan copy\fR command takes care of that
+automatically. However, it is necessary to enter the event loop by
+using the \fBvwait\fR command or by using Tk.
+.PP
+You are not allowed to do other I/O operations with \fIinputChan\fR or
+\fIoutputChan\fR during a background \fBchan copy\fR. If either
+\fIinputChan\fR or \fIoutputChan\fR get closed while the copy is in
+progress, the current copy is stopped and the command callback is
+\fInot\fR made. If \fIinputChan\fR is closed, then all data already
+queued for \fIoutputChan\fR is written out.
+.PP
+Note that \fIinputChan\fR can become readable during a background
+copy. You should turn off any \fBchan event\fR or \fBfileevent\fR
+handlers during a background copy so those handlers do not interfere
+with the copy. Any I/O attempted by a \fBchan event\fR or
+\fBfileevent\fR handler will get a
+.QW "channel busy"
+error.
+.PP
+\fBChan copy\fR translates end-of-line sequences in \fIinputChan\fR
+and \fIoutputChan\fR according to the \fB\-translation\fR option for
+these channels (see \fBchan configure\fR above). The translations
+mean that the number of bytes read from \fIinputChan\fR can be
+different than the number of bytes written to \fIoutputChan\fR. Only
+the number of bytes written to \fIoutputChan\fR is reported, either as
+the return value of a synchronous \fBchan copy\fR or as the argument
+to the callback for an asynchronous \fBchan copy\fR.
+.PP
+\fBChan copy\fR obeys the encodings and character translations
+configured for the channels. This means that the incoming characters
+are converted internally first UTF-8 and then into the encoding of the
+channel \fBchan copy\fR writes to (see \fBchan configure\fR above for
+details on the \fB\-encoding\fR and \fB\-translation\fR options). No
+conversion is done if both channels are set to encoding \fBbinary\fR
+and have matching translations. If only the output channel is set to
+encoding \fBbinary\fR the system will write the internal UTF-8
+representation of the incoming characters. If only the input channel
+is set to encoding \fBbinary\fR the system will assume that the
+incoming bytes are valid UTF-8 characters and convert them according
+to the output encoding. The behaviour of the system for bytes which
+are not valid UTF-8 characters is undefined in this case.

+\fBchan create \fImode cmdPrefix\fR
+.
+This subcommand creates a new script level channel using the command
+prefix \fIcmdPrefix\fR as its handler. Any such channel is called a
+\fBreflected\fR channel. The specified command prefix, \fBcmdPrefix\fR,
+must be a non-empty list, and should provide the API described in the
+\fBreflectedchan\fR manual page. The handle of the new channel is
+returned as the result of the \fBchan create\fR command, and the
+channel is open. Use either \fBclose\fR or \fBchan close\fR to remove
+the channel.
+.RS
+.PP
+The argument \fImode\fR specifies if the new channel is opened for
+reading, writing, or both. It has to be a list containing any of the
+strings
+.QW \fBread\fR
+or
+.QW \fBwrite\fR .
+The list must have at least one
+element, as a channel you can neither write to nor read from makes no
+sense. The handler command for the new channel must support the chosen
+mode, or an error is thrown.
+.PP
+The command prefix is executed in the global namespace, at the top of
+call stack, following the appending of arguments as described in the
+\fBreflectedchan\fR manual page. Command resolution happens at the
+time of the call. Renaming the command, or destroying it means that
+the next call of a handler method may fail, causing the channel
+command invoking the handler to fail as well. Depending on the
+subcommand being invoked, the error message may not be able to explain
+the reason for that failure.
+.PP
+Every channel created with this subcommand knows which interpreter it
+was created in, and only ever executes its handler command in that
+interpreter, even if the channel was shared with and/or was moved into
+a different interpreter. Each reflected channel also knows the thread
+it was created in, and executes its handler command only in that
+thread, even if the channel was moved into a different thread. To this
+end all invocations of the handler are forwarded to the original
+thread by posting special events to it. This means that the original
+thread (i.e. the thread that executed the \fBchan create\fR command)
+must have an active event loop, i.e. it must be able to process such
+events. Otherwise the thread sending them will \fIblock
+indefinitely\fR. Deadlock may occur.
+.PP
+Note that this permits the creation of a channel whose two endpoints
+live in two different threads, providing a stream-oriented bridge
+between these threads. In other words, we can provide a way for
+regular stream communication between threads instead of having to send
+commands.
+.PP
+When a thread or interpreter is deleted, all channels created with
+this subcommand and using this thread/interpreter as their computing
+base are deleted as well, in all interpreters they have been shared
+with or moved into, and in whatever thread they have been transfered
+to. While this pulls the rug out under the other thread(s) and/or
+interpreter(s), this cannot be avoided. Trying to use such a channel
+will cause the generation of a regular error about unknown channel
+handles.
+.PP
+This subcommand is \fBsafe\fR and made accessible to safe
+interpreters. While it arranges for the execution of arbitrary Tcl
+code the system also makes sure that the code is always executed
+within the safe interpreter.

+\fBchan eof \fIchannelId\fR

+\fBchan event \fIchannelId event\fR ?\fIscript\fR?
+.
+Arrange for the Tcl script \fIscript\fR to be installed as a \fIfile
+event handler\fR to be called whenever the channel called
+\fIchannelId\fR enters the state described by \fIevent\fR (which must
+be either \fBreadable\fR or \fBwritable\fR); only one such handler may
+be installed per event per channel at a time. If \fIscript\fR is the
+empty string, the current handler is deleted (this also happens if the
+channel is closed or the interpreter deleted). If \fIscript\fR is
+omitted, the currently installed script is returned (or an empty
+string if no such handler is installed). The callback is only
+performed if the event loop is being serviced (e.g. via \fBvwait\fR or
+\fBupdate\fR).
+.RS
+.PP
+A file event handler is a binding between a channel and a script, such
+that the script is evaluated whenever the channel becomes readable or
+writable. File event handlers are most commonly used to allow data to
+be received from another process on an event-driven basis, so that the
+receiver can continue to interact with the user or with other channels
+while waiting for the data to arrive. If an application invokes
+\fBchan gets\fR or \fBchan read\fR on a blocking channel when there is
+no input data available, the process will block; until the input data
+arrives, it will not be able to service other events, so it will
+appear to the user to
+.QW "freeze up" .
+With \fBchan event\fR, the
+process can tell when data is present and only invoke \fBchan gets\fR
+or \fBchan read\fR when they will not block.
+.PP
+A channel is considered to be readable if there is unread data
+available on the underlying device. A channel is also considered to
+be readable if there is unread data in an input buffer, except in the
+special case where the most recent attempt to read from the channel
+was a \fBchan gets\fR call that could not find a complete line in the
+input buffer. This feature allows a file to be read a line at a time
+in nonblocking mode using events. A channel is also considered to be
+readable if an end of file or error condition is present on the
+underlying file or device. It is important for \fIscript\fR to check
+for these conditions and handle them appropriately; for example, if
+there is no special check for end of file, an infinite loop may occur
+where \fIscript\fR reads no data, returns, and is immediately invoked
+again.
+.PP
+A channel is considered to be writable if at least one byte of data
+can be written to the underlying file or device without blocking, or
+if an error condition is present on the underlying file or device.
+Note that client sockets opened in asynchronous mode become writable
+when they become connected or if the connection fails.
+.PP
+Event-driven I/O works best for channels that have been placed into
+nonblocking mode with the \fBchan configure\fR command. In blocking
+mode, a \fBchan puts\fR command may block if you give it more data
+than the underlying file or device can accept, and a \fBchan gets\fR
+or \fBchan read\fR command will block if you attempt to read more data
+than is ready; no events will be processed while the commands block.
+In nonblocking mode \fBchan puts\fR, \fBchan read\fR, and \fBchan
+gets\fR never block.
+.PP
+The script for a file event is executed at global level (outside the
+context of any Tcl procedure) in the interpreter in which the \fBchan
+event\fR command was invoked. If an error occurs while executing the
+script then the command registered with \fBinterp bgerror\fR is used
+to report the error. In addition, the file event handler is deleted
+if it ever returns an error; this is done in order to prevent infinite
+loops due to buggy handlers.

+Tcl buffers output internally, so characters written with \fBchan

+When the output buffer fills up, the \fBchan puts\fR command will
+normally block until all the buffered data has been accepted for

+mode then the \fBchan puts\fR command will not block even if the
+operating system cannot accept the data. Instead, Tcl continues to
+buffer the data and writes it in the background as fast as the
+underlying file or device can accept it. The application must use the
+Tcl event loop for nonblocking output to work; otherwise Tcl never
+finds out that the file or device is ready for more output data. It
+is possible for an arbitrarily large amount of data to be buffered for

+The \fBclock add\fR command performs clock arithmetic on a value

+given as its first argument. The remaining arguments (other than the

+Addition of seconds, minutes and hours is fairly straightforward;
+the given time increment (times sixty for minutes, or 3600 for hours)
+is simply added to the \fItimeVal\fR given
+to the \fBclock add\fR command. The result is interpreted as
+a nominal number of seconds from the Epoch.
+.PP
+Surprising results
+may be obtained when crossing a point at which a leap second is
+inserted or removed; the \fBclock add\fR command simply ignores
+leap seconds and therefore assumes that times come in sequence,
+23:59:58, 23:59:59, 00:00:00. (This assumption is handled by
+the fact that Tcl's model of time reacts to leap seconds by speeding
+or slowing the clock by a minuscule amount until Tcl's time
+is back in step with the world.
+.PP
+The fact that adding and subtracting hours is defined in terms of
+absolute time means that it will add fixed amounts of time in time zones
+that observe summer time (Daylight Saving Time). For example,
+the following code sets the value of \fBx\fR to \fB04:00:00\fR because
+the clock has changed in the interval in question.

+Adding and subtracting days and weeks is accomplished by converting
+the given time to a calendar day and time of day in the appropriate
+time zone and locale. The requisite number of days (weeks are converted
+to days by multiplying by seven) is added to the calendar day, and
+the date and time are then converted back to a count of seconds from
+the epoch time.
+.PP
+Adding and subtracting a given number of days across the point that
+the time changes at the start or end of summer time (Daylight Saving Time)

+adds the requisite number of months or years, and reconverts the resulting
+date and time of day to an absolute time.
+.PP
+If the resulting date is impossible because the month has too few days
+(for example, when adding 1 month to 31 January), the last day of the
+month is substituted. Thus, adding 1 month to 31 January will result in
+28 February in a common year or 29 February in a leap year.
+.PP
+The rules for handling anomalies relating to summer time and to the
+Gregorian calendar are the same when adding/subtracting months and
+years as they are when adding/subtracting days and weeks.
+.PP
+If multiple \fIcount unit\fR pairs are present on the command, they
+are evaluated consecutively, from left to right.
+.SH "HIGH RESOLUTION TIMERS"
+Most of the subcommands supported by the \fBclock\fR command deal with
+times represented as a count of seconds from the epoch time, and this is the
+representation that \fBclock seconds\fR returns. There are three exceptions,
+which are all intended for use where higher-resolution times are required.
+\fBclock milliseconds\fR returns the count of milliseconds from the
+epoch time, and \fBclock microseconds\fR returns the count of microseconds
+from the epoch time. In addition, there is a \fBclock clicks\fR command
+that returns a platform-dependent high-resolution timer. Unlike
+\fBclock seconds\fR and \fBclock milliseconds\fR, the value
+of \fBclock clicks\fR is not guaranteed to be tied to any fixed
+epoch; it is simply intended to be the most precise interval timer
+available, and is intended only for relative timing studies such as
+benchmarks.
+.SH "FORMATTING TIMES"
+The \fBclock format\fR command produces times for display to a user
+or writing to an external medium. The command accepts times that are
+expressed in seconds from the epoch time of 1 January 1970, 00:00 UTC,
+as returned by \fBclock seconds\fR, \fBclock scan\fR, \fBclock add\fR,
+\fBfile atime\fR or \fBfile mtime\fR.
+.PP
+If a \fB\-format\fR option is present, the following argument is
+a string that specifies how the date and time are to be formatted.
+The string consists
+of any number of characters other than the per-cent sign
+.PQ \fB%\fR
+interspersed with any number of \fIformat groups\fR, which are two-character
+sequences beginning with the per-cent sign. The permissible format groups,
+and their interpretation, are described under \fBFORMAT GROUPS\fR.
+.PP
+If a \fB\-timezone\fR option is present, the following
+argument is a string that specifies the time zone in which the date and time
+are to be formatted. As an alternative to
+.QW "\fB\-timezone\fR \fI:UTC\fR" ,
+the obsolete usage
+.QW "\fB\-gmt\fR \fItrue\fR"
+may be used. See
+\fBTIME ZONES\fR for the permissible variants for the time zone.
+.PP
+If a \fB\-locale\fR option is present, the following argument is
+a string that specifies the locale in which the time is to be formatted,
+in the same format that is used for the \fBmsgcat\fR package. Note
+that the default, if \fB\-locale\fR is not specified, is the root locale
+\fB{}\fR rather than the current locale. The current locale may
+be obtained by using \fB\-locale\fR \fBcurrent\fR.
+In addition, some platforms support a \fBsystem\fR locale that
+reflects the user's current choices. For instance, on Windows, the
+format that the user has selected from dates and times in the Control
+Panel can be obtained by using the \fBsystem\fR locale. On
+platforms that do not define a user selection of date and time formats
+separate from \fBLC_TIME\fR, \fB\-locale\fR \fBsystem\fR is
+synonymous with \fB\-locale\fR \fBcurrent\fR.
+.SH "SCANNING TIMES"
+The \fBclock scan\fR command accepts times that are formatted as
+strings and converts them to counts of seconds from the epoch time
+of 1 January 1970, 00:00 UTC. It normally takes a \fB\-format\fR
+option that is followed by a string describing
+the expected format of the input. (See
+\fBFREE FORM SCAN\fR for the effect of \fBclock scan\fR
+without such an argument.) The string consists of any number of
+characters other than the per-cent sign
+.PQ \fB%\fR "" ,
+interspersed with any number of \fIformat groups\fR, which are two-character
+sequences beginning with the per-cent sign. The permissible format groups,
+and their interpretation, are described under \fBFORMAT GROUPS\fR.
+.PP
+If a \fB\-timezone\fR option is present, the following
+argument is a string that specifies the time zone in which the date and time
+are to be interpreted. As an alternative to \fB\-timezone\fR \fI:UTC\fR,
+the obsolete usage \fB\-gmt\fR \fItrue\fR may be used. See
+\fBTIME ZONES\fR for the permissible variants for the time zone.
+.PP
+If a \fB\-locale\fR option is present, the following argument is
+a string that specifies the locale in which the time is to be interpreted,

+synonymous with \fB\-locale\fR \fBcurrent\fR.
+.PP
+If a \fB\-base\fR option is present, the following argument is
+a time (expressed in seconds from the epoch time) that is used as
+a \fIbase time\fR for interpreting relative times. If no
+\fB\-base\fR option is present, the base time is the current time.
+.PP
+Scanning of times in fixed format works by determining three things:
+the date, the time of day, and the time zone. These three are then
+combined into a point in time, which is returned as the number of seconds
+from the epoch.
+.PP
+Before scanning begins, the format string is preprocessed
+to replace \fB%c\fR, \fB%Ec\fR, \fB%x\fR, \fB%Ex\fR,
+\fB%X\fR. \fB%Ex\fR, \fB%r\fR, \fB%R\fR, \fB%T\fR,
+\fB%D\fR, \fB%EY\fR and \fB%+\fR format groups with counterparts
+that are appropriate to the current locale and contain none of the
+above groups. For instance, \fB%D\fR will (in the \fBen_US\fR locale)
+be replaced with \fB%m/%d/%Y\fR.
+.PP
+The date is determined according to the fields that are present in the
+preprocessed format string. In order of preference:
+.IP [1]
+If the string contains a \fB%s\fR format group, representing
+seconds from the epoch, that group is used to determine the date.
+.IP [2]
+If the string contains a \fB%J\fR format group, representing
+the Julian Day Number, that group is used to determine the date.
+.IP [3]
+If the string contains a complete set of format groups specifying
+century, year, month, and day of month; century, year, and day of year;
+or ISO8601 fiscal year, week of year, and day of week; those groups are
+combined and used to determine the date. If more than one complete
+set is present, the one at the rightmost position in the string is
+used.
+.IP [4]
+If the string lacks a century but contains a set of format
+groups specifying year of century, month and day of month; year of
+century and day of year; or two-digit ISO8601 fiscal year, week of year,
+and day of week; those groups are
+combined and used to determine the date. If more than one complete
+set is present, the one at the rightmost position in the string is
+used. The year is presumed to lie in the range 1938 to 2037 inclusive.
+.IP [5]
+If the string entirely lacks any specification for the year
+(or contains the year only on the locale's alternative calendar)
+and contains a set of format groups specifying month and day of month,
+day of year, or week of year and day of week, those groups are
+combined and used to determine the date. If more than one complete
+set is present, the one at the rightmost position in the string is
+used. The year is determined by interpreting the base time in the given
+time zone.
+.IP [6]
+If the string contains none of the above sets, but has a day
+of the month or day of the week, the day of the month or day of the week
+are used to determine the date by interpreting the base time in the
+given time zone and returning the given day of the current week or month.
+(The week runs from Monday to Sunday, ISO8601-fashion.) If both day
+of month and day of week are present, the day of the month takes
+priority.
+.IP [7]
+If none of the above rules results in a usable date, the date
+of the base time in the given time zone is used.
+.PP
+The time is also determined according to the fields that are present in the
+preprocessed format string. In order of preference:
+.IP [1]
+If the string contains a \fB%s\fR format group, representing
+seconds from the epoch, that group determines the time of day.
+.IP [2]
+If the string contains either an hour on the 24-hour clock
+or an hour on the 12-hour clock plus an AM/PM indicator, that hour determines
+the hour of the day. If the string further contains a group specifying
+the minute of the hour, that group combines with the hour. If the string
+further contains a group specifying the second of the minute, that group
+combines with the hour and minute.
+.IP [3]
+If the string contains neither a \fB%s\fR format group nor
+a group specifying the hour of the day, then midnight (\fB00:00\fR, the start
+of the given date) is used.
+The time zone is determined by either the \fB\-timezone\fR or \fB\-gmt\fR
+options, or by using the current time zone.
+.PP
+If a format string lacks a \fB%z\fR or \fB%Z\fR format group,
+it is possible for the time to be ambiguous because it appears twice
+in the same day, once without and once with Daylight Saving Time.
+If this situation occurs, the first occurrence of the time is chosen.
+(For this reason, it is wise to have the input string contain the
+time zone when converting local times. This caveat does not apply to
+UTC times.)
+.SH "FORMAT GROUPS"
+The following format groups are recognized by the \fBclock scan\fR and
+\fBclock format\fR commands.
+.TP
+\fB%a\fR
+On output, receives an abbreviation (\fIe.g.,\fR \fBMon\fR) for the day

-Convert \fIdateString\fR to an integer clock value (see \fBclock seconds\fR).
-This command can parse and convert virtually any standard date and/or time
-string, which can include standard time zone mnemonics. If only a time is
-specified, the current date is assumed. If the string does not contain a

+\fB%C\fR
+On output, receives the number of the century in Indo-Arabic numerals.
+On input, matches one or two digits, possibly with leading whitespace,
+that are expected to be the number of the century.

+digits. On input, matches one or two digits, possibly with leading
+whitespace, that are expected to be the number of the day of the month.
+.TP
+\fB%D\fR
+This format group is synonymous with \fB%m/%d/%Y\fR. It should be
+used only in exchanging data within the \fBen_US\fR locale, since
+other locales typically do not use this order for the fields of the date.
+.TP
+\fB%e\fR
+On output, produces the number of the day of the month, as one or
+two decimal digits (with a leading blank for one-digit dates).
+On input, matches one or two digits, possibly with leading
+whitespace, that are expected to be the number of the day of the month.
+.TP
+\fB%Ec\fR
+On output, produces a locale-dependent representation of the date and
+time of day in the locale's alternative calendar. On input, matches
+whatever \fB%Ec\fR produces. The locale's alternative calendar need not
+be the Gregorian calendar.
+.TP
+\fB%EC\fR
+On output, produces a locale-dependent name of an era in the locale's
+alternative calendar. On input, matches the name of the era or any
+unique prefix.
+.TP
+\fB%EE\fR
+On output, produces the string \fBB.C.E.\fR or \fBC.E.\fR, or a
+string of the same meaning in the locale, to indicate whether \fB%Y\fR refers
+to years before or after Year 1 of the Common Era. On input, accepts
+the string \fBB.C.E.\fR, \fBB.C.\fR, \fBC.E.\fR, \fBA.D.\fR, or the
+abbreviation appropriate to the current locale, and uses it to fix
+whether \fB%Y\fR refers to years before or after Year 1 of the
+Common Era.
+.TP
+\fB%Ex\fR
+On output, produces a locale-dependent representation of the date
+in the locale's alternative calendar. On input, matches

+produces. Often synonymous with \fB%EC%Ey\fR.
+.TP
+\fB%g\fR
+On output, produces a two-digit year number suitable for use with
+the week-based ISO8601 calendar; that is, the year number corresponds
+to the week number produced by \fB%V\fR. On input, accepts such

+(001-366). On input, accepts such a number.
+.TP
+\fB%J\fR
+On output, produces a string of digits giving the Julian Day Number.
+On input, accepts a string of digits and interprets it as a Julian Day Number.
+The Julian Day Number is a count of the number of calendar days
+that have elapsed since 1 January, 4713 BCE of the proleptic
+Julian calendar. The epoch time of 1 January 1970 corresponds
+to Julian Day Number 2440588.

+.TP
+\fB%p\fR
+On output, produces an indicator for the part of the day, \fBAM\fR
+or \fBPM\fR, appropriate to the given locale. If the script of the

+\fB%R\fR
+On output, produces a locale-dependent time of day representation on a
+24-hour clock. On input, accepts whatever \fB%R\fR produces.
+.TP
+\fB%s\fR
+On output, simply formats the \fItimeVal\fR argument as a decimal
+integer and inserts it into the output string. On input, accepts
+a decimal integer and uses is as the time value without any further
+processing. Since \fB%s\fR uniquely determines a point in time, it
+overrides all other input formats.
+.TP
+\fB%S\fR
+On output, produces a two-digit number of the second of the minute
+(00-59). On input, accepts two digits and uses them as the second of the
+minute.
+.TP
+\fB%t\fR
+On output, produces a TAB character. On input, matches a TAB character.
+.TP
+\fB%T\fR
+Synonymous with \fB%H:%M:%S\fR.
+.TP
+\fB%u\fR
+On output, produces the number of the day of the week
+(\fB1\fR\(->Monday, \fB7\fR\(->Sunday). On input, accepts a single digit and

+\fB7\fR.
+.TP
+\fB%U\fR
+On output, produces the ordinal number of the week of the year
+(00-53). The first Sunday of the year is the first day of week 01. On
+input accepts two digits which are otherwise ignored. This format
+group is never used in determining an input date. This interpretation
+of the week of the year was once common in US banking but is now
+largely obsolete. See \fB%V\fR for the ISO8601 week number.
+.TP
+\fB%V\fR
+On output, produces the number of the ISO8601 week as a two digit
+number (01-53). Week 01 is the week containing January 4; or the first
+week of the year containing at least 4 days; or the week containing
+the first Thursday of the year (the three statements are
+equivalent). Each week begins on a Monday. On input, accepts the
+ISO8601 week number.
+.TP
+\fB%w\fR
+On output, produces the ordinal number of the day of the week
+(Sunday==0; Saturday==6). On input, accepts a single digit and
+interprets it as the day of the week; Sunday may be represented as
+either 0 or 7. Note that \fB%w\fR is not the ISO8601 weekday number,
+which is produced and accepted by \fB%u\fR.

+\fB%W\fR
+On output, produces a week number (00-53) within the year; week 01
+begins on the first Monday of the year. On input, accepts two digits,

+\fB%x\fR
+On output, produces the date in a locale-dependent representation. On
+input, accepts whatever \fB%x\fR produces and is used to determine
+calendar date.

+\fB%X\fR
+On output, produces the time of day in a locale-dependent
+representation. On input, accepts whatever \fB%X\fR produces and is used
+to determine time of day.
+.TP
+\fB%y\fR
+On output, produces the two-digit year of the century. On input,
+accepts two digits, and is used to determine calendar date. The
+date is presumed to lie between 1938 and 2037 inclusive. Note
+that \fB%y\fR does not yield a year appropriate for use with the ISO8601
+week number \fB%V\fR; programs should use \fB%g\fR for that purpose.

+\fB%Y\fR
+On output, produces the four-digit calendar year. On input,
+accepts four digits and may be used to determine calendar date. Note
+that \fB%Y\fR does not yield a year appropriate for use with the ISO8601
+week number \fB%V\fR; programs should use \fB%G\fR for that purpose.

+\fB%z\fR
+On output, produces the current time zone, expressed in hours and

+time zone. This option should, in general, be used on input only when
+parsing RFC822 dates. Other uses are fraught with ambiguity; for

+\fBdict \fIoption arg \fR?\fIarg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+Performs one of several operations on dictionary values or variables
+containing dictionary values (see the \fBDICTIONARY VALUES\fR section
+below for a description), depending on \fIoption\fR. The legal
+\fIoption\fRs (which may be abbreviated) are:
+.TP
+\fBdict append \fIdictionaryVariable key \fR?\fIstring ...\fR?
+This appends the given string (or strings) to the value that the given
+key maps to in the dictionary value contained in the given variable,
+writing the resulting dictionary value back to that variable.
+Non-existent keys are treated as if they map to an empty string.
+.TP
+\fBdict create \fR?\fIkey value ...\fR?
+Create a new dictionary that contains each of the key/value mappings
+listed as arguments (keys and values alternating, with each key being
+followed by its associated value.)
+.TP
+\fBdict exists \fIdictionaryValue key \fR?\fIkey ...\fR?
+This returns a boolean value indicating whether the given key (or path
+of keys through a set of nested dictionaries) exists in the given
+dictionary value. This returns a true value exactly when \fBdict
+get\fR on that path will succeed.
+.TP
+\fBdict filter \fIdictionaryValue filterType arg \fR?\fIarg ...\fR?
+This takes a dictionary value and returns a new dictionary that
+contains just those key/value pairs that match the specified filter
+type (which may be abbreviated.) Supported filter types are:
+.RS
+.TP
+\fBdict filter \fIdictionaryValue \fBkey \fIglobPattern\fR
+The key rule only matches those key/value pairs whose keys match the
+given pattern (in the style of \fBstring match\fR.)
+.TP
+\fBdict filter \fIdictionaryValue \fBscript {\fIkeyVar valueVar\fB} \fIscript\fR
+The script rule tests for matching by assigning the key to the
+\fIkeyVar\fR and the value to the \fIvalueVar\fR, and then evaluating
+the given script which should return a boolean value (with the
+key/value pair only being included in the result of the \fBdict
+filter\fR when a true value is returned.) Note that the first
+argument after the rule selection word is a two-element list. If the
+\fIscript\fR returns with a condition of \fBTCL_BREAK\fR, no further
+key/value pairs are considered for inclusion in the resulting
+dictionary, and a condition of \fBTCL_CONTINUE\fR is equivalent to a false
+result. The key/value pairs are tested in the order in which the keys
+were inserted into the dictionary.
+.TP
+\fBdict filter \fIdictionaryValue \fBvalue \fIglobPattern\fR
+The value rule only matches those key/value pairs whose values match
+the given pattern (in the style of \fBstring match\fR.)
+.RE
+.TP
+\fBdict for {\fIkeyVar valueVar\fB} \fIdictionaryValue body\fR
+This command takes three arguments, the first a two-element list of
+variable names (for the key and value respectively of each mapping in
+the dictionary), the second the dictionary value to iterate across,
+and the third a script to be evaluated for each mapping with the key
+and value variables set appropriately (in the manner of \fBforeach\fR.)
+The result of the command is an empty string. If any evaluation of the
+body generates a \fBTCL_BREAK\fR result, no further pairs from the
+dictionary will be iterated over and the \fBdict for\fR command will
+terminate successfully immediately. If any evaluation of the body
+generates a \fBTCL_CONTINUE\fR result, this shall be treated exactly like a
+normal \fBTCL_OK\fR result. The order of iteration is the order in
+which the keys were inserted into the dictionary.
+.TP
+\fBdict get \fIdictionaryValue \fR?\fIkey ...\fR?
+Given a dictionary value (first argument) and a key (second argument),
+this will retrieve the value for that key. Where several keys are
+supplied, the behaviour of the command shall be as if the result of
+\fBdict get $dictVal $key\fR was passed as the first argument to
+\fBdict get\fR with the remaining arguments as second (and possibly
+subsequent) arguments. This facilitates lookups in nested
+dictionaries. For example, the following two commands are equivalent:
+.RS
+.PP
+.CS
+dict get $dict foo bar spong
+dict get [dict get [dict get $dict foo] bar] spong
+.CE
+.PP
+If no keys are provided, \fBdict get\fR will return a list containing pairs of
+elements in a manner similar to \fBarray get\fR. That is, the first
+element of each pair would be the key and the second element would be
+the value for that key.
+.PP
+It is an error to attempt to retrieve a value for a key that is not
+present in the dictionary.
+.RE
+.TP
+\fBdict incr \fIdictionaryVariable key \fR?\fIincrement\fR?
+This adds the given increment value (an integer that defaults to 1 if
+not specified) to the value that the given key maps to in the
+dictionary value contained in the given variable, writing the
+resulting dictionary value back to that variable. Non-existent keys
+are treated as if they map to 0. It is an error to increment a value
+for an existing key if that value is not an integer.
+.TP
+\fBdict info \fIdictionaryValue\fR
+This returns information (intended for display to people) about the
+given dictionary though the format of this data is dependent on the
+implementation of the dictionary. For dictionaries that are
+implemented by hash tables, it is expected that this will return the
+string produced by \fBTcl_HashStats\fR, similar to \fBarray statistics\fR.
+.TP
+\fBdict keys \fIdictionaryValue \fR?\fIglobPattern\fR?
+Return a list of all keys in the given dictionary value. If a pattern
+is supplied, only those keys that match it (according to the rules of
+\fBstring match\fR) will be returned. The returned keys will be in the
+order that they were inserted into the dictionary.
+.TP
+\fBdict lappend \fIdictionaryVariable key \fR?\fIvalue ...\fR?
+This appends the given items to the list value that the given key maps
+to in the dictionary value contained in the given variable, writing
+the resulting dictionary value back to that variable. Non-existent
+keys are treated as if they map to an empty list, and it is legal for
+there to be no items to append to the list. It is an error for the
+value that the key maps to to not be representable as a list.
+.TP
+\fBdict merge \fR?\fIdictionaryValue ...\fR?
+Return a dictionary that contains the contents of each of the
+\fIdictionaryValue\fR arguments. Where two (or more) dictionaries
+contain a mapping for the same key, the resulting dictionary maps that
+key to the value according to the last dictionary on the command line
+containing a mapping for that key.
+.TP
+\fBdict remove \fIdictionaryValue \fR?\fIkey ...\fR?
+Return a new dictionary that is a copy of an old one passed in as
+first argument except without mappings for each of the keys listed.
+It is legal for there to be no keys to remove, and it also legal for
+any of the keys to be removed to not be present in the input
+dictionary in the first place.
+.TP
+\fBdict replace \fIdictionaryValue \fR?\fIkey value ...\fR?
+Return a new dictionary that is a copy of an old one passed in as
+first argument except with some values different or some extra
+key/value pairs added. It is legal for this command to be called with
+no key/value pairs, but illegal for this command to be called with a
+key but no value.
+.TP
+\fBdict set \fIdictionaryVariable key \fR?\fIkey ...\fR? \fIvalue\fR
+This operation takes the name of a variable containing a dictionary
+value and places an updated dictionary value in that variable
+containing a mapping from the given key to the given value. When
+multiple keys are present, this operation creates or updates a chain
+of nested dictionaries.
+.TP
+\fBdict size \fIdictionaryValue\fR
+Return the number of key/value mappings in the given dictionary value.
+.TP
+\fBdict unset \fIdictionaryVariable key \fR?\fIkey ...\fR?
+This operation (the companion to \fBdict set\fR) takes the name of a
+variable containing a dictionary value and places an updated
+dictionary value in that variable that does not contain a mapping for
+the given key. Where multiple keys are present, this describes a path
+through nested dictionaries to the mapping to remove. At least one key
+must be specified, but the last key on the key-path need not exist.
+All other components on the path must exist.

+.SH "DICTIONARY VALUES"
+.PP
+Dictionaries are values that contain an efficient, order-preserving
+mapping from arbitrary keys to arbitrary values.
+Each key in the dictionary maps to a single value.
+They have a textual format that is exactly that of any list with an
+even number of elements, with each mapping in the dictionary being
+represented as two items in the list. When a command takes a
+dictionary and produces a new dictionary based on it (either returning
+it or writing it back into the variable that the starting dictionary
+was read from) the new dictionary will have the same order of keys,
+modulo any deleted keys and with new keys added on to the end.
+When a string is interpreted as a dictionary and it would otherwise
+have duplicate keys, only the last value for a particular key is used;
+the others are ignored, meaning that,
+.QW "apple banana"
+and
+.QW "apple carrot apple banana"
+are equivalent dictionaries (with different string representations).
+.PP
+Operations that derive a new dictionary from an old one (e.g., updates
+like \fBdict set\fR and \fBdict unset\fR) preserve the order of keys
+in the dictionary. The exceptions to this are for any new keys they
+add, which are appended to the sequence, and any keys that are
+removed, which are excised from the order.

A Tcl expression consists of a combination of operands, operators,
and parentheses.
White space may be used between the operands and operators and
parentheses; it is ignored by the expression's instructions.
Where possible, operands are interpreted as integer values.
-Integer values may be specified in decimal (the normal case), in octal (if the
-first character of the operand is \fB0\fR), or in hexadecimal (if the first
-two characters of the operand are \fB0x\fR).

+Integer values may be specified in decimal (the normal case), in binary
+(if the first two characters of the operand are \fB0b\fR), in octal
+(if the first two characters of the operand are \fB0o\fR), or in hexadecimal
+(if the first two characters of the operand are \fB0x\fR). For
+compatibility with older Tcl releases, an octal integer value is also
+indicated simply when the first character of the operand is \fB0\fR,
+whether or not the second character is also \fBo\fR.
If an operand does not have one of the integer formats given
above, then it is treated as a floating-point number if that is
-possible. Floating-point numbers may be specified in any of the
-ways accepted by an ANSI-compliant C compiler (except that the
-\fBf\fR, \fBF\fR, \fBl\fR, and \fBL\fR suffixes will not be permitted in

following are valid floating-point numbers: 2.1, 3., 6e4, 7.91e+16.
+Also recognized as floating point values are the strings \fBInf\fR
+and \fBNaN\fR making use of any case for each character.
+.VE 8.5
If no numeric interpretation is possible (note that all literal
operands that are not numeric or boolean must be quoted with either
braces or with double quotes), then an operand is left as a string

+When a limit is exceeded for an interpreter, first any handler callbacks

+.SH "DESCRIPTION"
+.PP
+The \fBexpr\fR command handles mathematical functions of the form
+\fBsin($x)\fR or \fBatan2($y,$x)\fR by converting them to calls of the
+form \fB[tcl::mathfunc::sin [expr {$x}]]\fR or
+\fB[tcl::mathfunc::atan2 [expr {$y}] [expr {$x}]]\fR.
+A number of math functions are available by default within the
+namespace \fB::tcl::mathfunc\fR; these functions are also available
+for code apart from \fBexpr\fR, by invoking the given commands
+directly.
+.PP
+Tcl supports the following mathematical functions in expressions, all
+of which work solely with floating-point numbers unless otherwise noted:
+.DS
+.ta 3c 6c 9c
+\fBabs\fR \fBacos\fR \fBasin\fR \fBatan\fR
+\fBatan2\fR \fBbool\fR \fBceil\fR \fBcos\fR
+\fBcosh\fR \fBdouble\fR \fBentier\fR \fBexp\fR
+\fBfloor\fR \fBfmod\fR \fBhypot\fR \fBint\fR
+\fBisqrt\fR \fBlog\fR \fBlog10\fR \fBmax\fR
+\fBmin\fR \fBpow\fR \fBrand\fR \fBround\fR
+\fBsin\fR \fBsinh\fR \fBsqrt\fR \fBsrand\fR
+\fBtan\fR \fBtanh\fR \fBwide\fR
+.DE
+.PP
+In addition to these predefined functions, applications may
+define additional functions by using \fBproc\fR (or any other method,
+such as \fBinterp alias\fR or \fBTcl_CreateObjCommand\fR) to define
+new commands in the \fBtcl::mathfunc\fR namespace. In addition, an
+obsolete interface named \fBTcl_CreateMathFunc\fR() is available to
+extensions that are written in C. The latter interface is not recommended
+for new implementations.
+.SS "DETAILED DEFINITIONS"
+.TP
+\fBabs \fIarg\fR
+Returns the absolute value of \fIarg\fR. \fIArg\fR may be either
+integer or floating-point, and the result is returned in the same form.
+.TP
+\fBacos \fIarg\fR
+Returns the arc cosine of \fIarg\fR, in the range [\fI0\fR,\fIpi\fR]
+radians. \fIArg\fR should be in the range [\fI\-1\fR,\fI1\fR].
+.TP
+\fBasin \fIarg\fR
+Returns the arc sine of \fIarg\fR, in the range [\fI\-pi/2\fR,\fIpi/2\fR]
+radians. \fIArg\fR should be in the range [\fI\-1\fR,\fI1\fR].
+.TP
+\fBatan \fIarg\fR
+Returns the arc tangent of \fIarg\fR, in the range [\fI\-pi/2\fR,\fIpi/2\fR]
+radians.
+.TP
+\fBatan2 \fIy x\fR
+Returns the arc tangent of \fIy\fR/\fIx\fR, in the range [\fI\-pi\fR,\fIpi\fR]
+radians. \fIx\fR and \fIy\fR cannot both be 0. If \fIx\fR is greater
+than \fI0\fR, this is equivalent to
+.QW "\fBatan \fR[\fBexpr\fR {\fIy\fB/\fIx\fR}]" .
+.TP
+\fBbool \fIarg\fR
+Accepts any numeric value, or any string acceptable to
+\fBstring is boolean\fR, and returns the corresponding
+boolean value \fB0\fR or \fB1\fR. Non-zero numbers are true.
+Other numbers are false. Non-numeric strings produce boolean value in
+agreement with \fBstring is true\fR and \fBstring is false\fR.
+.TP
+\fBceil \fIarg\fR
+Returns the smallest integral floating-point value (i.e. with a zero
+fractional part) not less than \fIarg\fR. The argument may be any
+numeric value.
+.TP
+\fBcos \fIarg\fR
+Returns the cosine of \fIarg\fR, measured in radians.
+.TP
+\fBcosh \fIarg\fR
+Returns the hyperbolic cosine of \fIarg\fR. If the result would cause
+an overflow, an error is returned.
+.TP
+\fBdouble \fIarg\fR
+The argument may be any numeric value,
+If \fIarg\fR is a floating-point value, returns \fIarg\fR, otherwise converts
+\fIarg\fR to floating-point and returns the converted value. May return
+\fBInf\fR or \fB\-Inf\fR when the argument is a numeric value that exceeds
+the floating-point range.
+.TP
+\fBentier \fIarg\fR
+.VS 8.5
+The argument may be any numeric value. The integer part of \fIarg\fR
+is determined and returned. The integer range returned by this function
+is unlimited, unlike \fBint\fR and \fBwide\fR which
+truncate their range to fit in particular storage widths.
+.VE 8.5
+.TP
+\fBexp \fIarg\fR
+Returns the exponential of \fIarg\fR, defined as \fIe\fR**\fIarg\fR.
+If the result would cause an overflow, an error is returned.
+.TP
+\fBfloor \fIarg\fR
+Returns the largest integral floating-point value (i.e. with a zero
+fractional part) not greater than \fIarg\fR. The argument may be
+any numeric value.
+.TP
+\fBfmod \fIx y\fR
+Returns the floating-point remainder of the division of \fIx\fR by
+\fIy\fR. If \fIy\fR is 0, an error is returned.
+.TP
+\fBhypot \fIx y\fR
+Computes the length of the hypotenuse of a right-angled triangle
+.QW "\fBsqrt\fR [\fBexpr\fR {\fIx\fB*\fIx\fB+\fIy\fB*\fIy\fR}]".
+.TP
+\fBint \fIarg\fR
+The argument may be any numeric value. The integer part of \fIarg\fR
+is determined, and then the low order bits of that integer value up
+to the machine word size are returned as an integer value. For reference,
+the number of bytes in the machine word are stored in
+\fBtcl_platform(wordSize)\fR.
+.TP
+\fBisqrt \fIarg\fR
+Computes the integer part of the square root of \fIarg\fR. \fIArg\fR must be
+a positive value, either an integer or a floating point number.
+Unlike \fBsqrt\fR, which is limited to the precision of a floating point
+number, \fIisqrt\fR will return a result of arbitrary precision.
+.TP
+\fBlog \fIarg\fR
+Returns the natural logarithm of \fIarg\fR. \fIArg\fR must be a
+positive value.
+.TP
+\fBlog10 \fIarg\fR
+Returns the base 10 logarithm of \fIarg\fR. \fIArg\fR must be a
+positive value.
+.TP
+\fBmax \fIarg\fB \fI...\fR
+Accepts one or more numeric arguments. Returns the one argument
+with the greatest value.
+.TP
+\fBmin \fIarg\fB \fI...\fR
+Accepts one or more numeric arguments. Returns the one argument
+with the least value.
+.TP
+\fBpow \fIx y\fR
+Computes the value of \fIx\fR raised to the power \fIy\fR. If \fIx\fR
+is negative, \fIy\fR must be an integer value.
+.TP
+\fBrand\fR
+Returns a pseudo-random floating-point value in the range (\fI0\fR,\fI1\fR).
+The generator algorithm is a simple linear congruential generator that
+is not cryptographically secure. Each result from \fBrand\fR completely
+determines all future results from subsequent calls to \fBrand\fR, so
+\fBrand\fR should not be used to generate a sequence of secrets, such as
+one-time passwords. The seed of the generator is initialized from the
+internal clock of the machine or may be set with the \fBsrand\fR function.
+.TP
+\fBround \fIarg\fR
+If \fIarg\fR is an integer value, returns \fIarg\fR, otherwise converts
+\fIarg\fR to integer by rounding and returns the converted value.
+.TP
+\fBsin \fIarg\fR
+Returns the sine of \fIarg\fR, measured in radians.
+.TP
+\fBsinh \fIarg\fR
+Returns the hyperbolic sine of \fIarg\fR. If the result would cause
+an overflow, an error is returned.
+.TP
+\fBsqrt \fIarg\fR
+The argument may be any non-negative numeric value. Returns a floating-point
+value that is the square root of \fIarg\fR. May return \fBInf\fR when the
+argument is a numeric value that exceeds the square of the maximum value of
+the floating-point range.
+.TP
+\fBsrand \fIarg\fR
+The \fIarg\fR, which must be an integer, is used to reset the seed for
+the random number generator of \fBrand\fR. Returns the first random
+number (see \fBrand\fR) from that seed. Each interpreter has its own seed.
+.TP
+\fBtan \fIarg\fR
+Returns the tangent of \fIarg\fR, measured in radians.
+.TP
+\fBtanh \fIarg\fR
+Returns the hyperbolic tangent of \fIarg\fR.
+.TP
+\fBwide \fIarg\fR
+The argument may be any numeric value. The integer part of \fIarg\fR
+is determined, and then the low order 64 bits of that integer value
+are returned as an integer value.

+.SH DESCRIPTION
+.PP
+The commands in the \fB::tcl::mathop\fR namespace implement the same set of
+operations as supported by the \fBexpr\fR command. All are exported from the
+namespace, but are not imported into any other namespace by default. Note that
+renaming, reimplementing or deleting any of the commands in the namespace does
+\fInot\fR alter the way that the \fBexpr\fR command behaves, and nor does
+defining any new commands in the \fB::tcl::mathop\fR namespace.
+.PP
+The following operator commands are supported:
+.DS
+.ta 2c 4c 6c 8c
+\fB~\fR \fB!\fR \fB+\fR \fB\-\fR \fB*\fR
+\fB/\fR \fB%\fR \fB**\fR \fB&\fR \fB|\fR
+\fB^\fR \fB>>\fR \fB<<\fR \fB==\fR \fBeq\fR
+\fB!=\fR \fBne\fR \fB<\fR \fB<=\fR \fB>\fR
+\fB>=\fR \fBin\fR \fBni\fR
+.DE
+.SS "MATHEMATICAL OPERATORS"
+.PP
+The behaviors of the mathematical operator commands are as follows:
+.TP
+\fB!\fR \fIboolean\fR
+.
+Returns the boolean negation of \fIboolean\fR, where \fIboolean\fR may be any
+numeric value or any other form of boolean value (i.e. it returns truth if the
+argument is falsity or zero, and falsity if the argument is truth or
+non-zero).
+.TP
+\fB+\fR ?\fInumber\fR ...?
+.
+Returns the sum of arbitrarily many arguments. Each \fInumber\fR argument may
+be any numeric value. If no arguments are given, the result will be zero (the
+summation identity).
+.TP
+\fB\-\fR \fInumber\fR ?\fInumber\fR ...?
+.
+If only a single \fInumber\fR argument is given, returns the negation of that
+numeric value. Otherwise returns the number that results when all subsequent
+numeric values are subtracted from the first one. All \fInumber\fR arguments
+must be numeric values. At least one argument must be given.
+.TP
+\fB*\fR ?\fInumber\fR ...?
+.
+Returns the product of arbitrarily many arguments. Each \fInumber\fR may be
+any numeric value. If no arguments are given, the result will be one (the
+multiplicative identity).
+.TP
+\fB/\fR \fInumber\fR ?\fInumber\fR ...?
+.
+If only a single \fInumber\fR argument is given, returns the reciprocal of that
+numeric value (i.e. the value obtained by dividing 1.0 by that value).
+Otherwise returns the number that results when the first numeric argument is
+divided by all subsequent numeric arguments. All \fInumber\fR arguments must
+be numeric values. At least one argument must be given.
+.RS
+.PP
+Note that when the leading values in the list of arguments are integers,
+integer division will be used for those initial steps (i.e. the intermediate
+results will be as if the functions \fIfloor\fR and \fIint\fR are applied to
+them, in that order). If all values in the operation are integers, the result
+will be an integer.
+.RE
+.TP
+\fB%\fR \fInumber number\fR
+.
+Returns the integral modulus of the first argument with respect to the second.
+Each \fInumber\fR must have an integral value. Note that Tcl defines this
+operation exactly even for negative numbers, so that the following equality
+holds true:
+.RS
+.CS
+(\fIx \fB/ \fIy\fR) \fB* \fIy \fB== \fIx \fB-\fR (\fIx \fB% \fIy\fR)
+.CE
+.RE
+.TP
+\fB**\fR ?\fInumber\fR ...?
+.
+Returns the result of raising each value to the power of the result of
+recursively operating on the result of processing the following arguments, so
+.QW "\fB** 2 3 4\fR"
+is the same as
+.QW "\fB** 2 [** 3 4]\fR" .
+Each \fInumber\fR may be
+any numeric value, though the second number must not be fractional if the
+first is negative. If no arguments are given, the result will be one, and if
+only one argument is given, the result will be that argument. The
+result will have an integral value only when all arguments are
+integral values.
+.SS "COMPARISON OPERATORS"
+.PP
+The behaviors of the comparison operator commands (most of which operate
+preferentially on numeric arguments) are as follows:
+.TP
+\fB==\fR ?\fIarg\fR ...?
+.
+Returns whether each argument is equal to the arguments on each side of it in
+the sense of the \fBexpr\fR == operator (\fIi.e.\fR, numeric comparison if
+possible, exact string comparison otherwise). If fewer than two arguments
+are given, this operation always returns a true value.
+.TP
+\fBeq\fR ?\fIarg\fR ...?
+.
+Returns whether each argument is equal to the arguments on each side of it
+using exact string comparison. If fewer than two arguments are given, this
+operation always returns a true value.
+.TP
+\fB!=\fR \fIarg arg\fR
+.
+Returns whether the two arguments are not equal to each other, in the sense of
+the \fBexpr\fR != operator (\fIi.e.\fR, numeric comparison if possible, exact
+string comparison otherwise).
+.TP
+\fBne\fR \fIarg arg\fR
+.
+Returns whether the two arguments are not equal to each other using exact
+string comparison.
+.TP
+\fB<\fR ?\fIarg\fR ...?
+.

+The \fBnamespace ensemble\fR is used to create and manipulate ensemble
+commands, which are commands formed by grouping subcommands together.
+The commands typically come from the current namespace when the
+ensemble was created, though this is configurable. Note that there
+may be any number of ensembles associated with any namespace
+(including none, which is true of all namespaces by default), though
+all the ensembles associated with a namespace are deleted when that
+namespace is deleted. The link between an ensemble command and its
+namespace is maintained however the ensemble is renamed.
+.PP
+Three subcommands of the \fBnamespace ensemble\fR command are defined:
+.TP
+\fBnamespace ensemble create\fR ?\fIoption value ...\fR?
+Creates a new ensemble command linked to the current namespace,
+returning the fully qualified name of the command created. The
+arguments to \fBnamespace ensemble create\fR allow the configuration
+of the command as if with the \fBnamespace ensemble configure\fR
+command. If not overridden with the \fB\-command\fR option, this
+command creates an ensemble with exactly the same name as the linked
+namespace. See the section \fBENSEMBLE OPTIONS\fR below for a full
+list of options supported and their effects.
+.TP
+\fBnamespace ensemble configure \fIcommand\fR ?\fIoption\fR? ?\fIvalue ...\fR?
+Retrieves the value of an option associated with the ensemble command
+named \fIcommand\fR, or updates some options associated with that
+ensemble command. See the section \fBENSEMBLE OPTIONS\fR below for a
+full list of options supported and their effects.
+.TP
+\fBnamespace ensemble exists\fR \fIcommand\fR
+Returns a boolean value that describes whether the command
+\fIcommand\fR exists and is an ensemble command. This command only
+ever returns an error if the number of arguments to the command is
+wrong.
+.PP
+When called, an ensemble command takes its first argument and looks it
+up (according to the rules described below) to discover a list of
+words to replace the ensemble command and subcommand with. The
+resulting list of words is then evaluated (with no further
+substitutions) as if that was what was typed originally (i.e. by
+passing the list of words through \fBTcl_EvalObjv\fR) and returning
+the result of the command. Note that it is legal to make the target
+of an ensemble rewrite be another (or even the same) ensemble
+command. The ensemble command will not be visible through the use of
+the \fBuplevel\fR or \fBinfo level\fR commands.
+.SS "ENSEMBLE OPTIONS"
+.PP
+The following options, supported by the \fBnamespace ensemble
+create\fR and \fBnamespace ensemble configure\fR commands, control how
+an ensemble command behaves:
+.TP
+\fB\-map\fR
+When non-empty, this option supplies a dictionary that provides a
+mapping from subcommand names to a list of prefix words to substitute
+in place of the ensemble command and subcommand words (in a manner
+similar to an alias created with \fBinterp alias\fR; the words are not
+reparsed after substitution). When this option is empty, the mapping
+will be from the local name of the subcommand to its fully-qualified
+name. Note that when this option is non-empty and the
+\fB\-subcommands\fR option is empty, the ensemble subcommand names
+will be exactly those words that have mappings in the dictionary.
+.TP
+\fB\-prefixes\fR
+This option (which is enabled by default) controls whether the
+ensemble command recognizes unambiguous prefixes of its subcommands.
+When turned off, the ensemble command requires exact matching of
+subcommand names.
+.TP
+\fB\-subcommands\fR
+When non-empty, this option lists exactly what subcommands are in the
+ensemble. The mapping for each of those commands will be either whatever
+is defined in the \fB\-map\fR option, or to the command with the same
+name in the namespace linked to the ensemble. If this option is
+empty, the subcommands of the namespace will either be the keys of the
+dictionary listed in the \fB\-map\fR option or the exported commands
+of the linked namespace at the time of the invocation of the ensemble
+command.
+.TP
+\fB\-unknown\fR
+When non-empty, this option provides a partial command (to which all
+the words that are arguments to the ensemble command, including the
+fully-qualified name of the ensemble, are appended) to handle the case
+where an ensemble subcommand is not recognized and would otherwise
+generate an error. When empty (the default) an error (in the style of
+\fBTcl_GetIndexFromObj\fR) is generated whenever the ensemble is
+unable to determine how to implement a particular subcommand. See
+\fBUNKNOWN HANDLER BEHAVIOUR\fR for more details.
+.PP
+The following extra option is allowed by \fBnamespace ensemble
+create\fR:
+.TP
+\fB\-command\fR
+This write-only option allows the name of the ensemble created by
+\fBnamespace ensemble create\fR to be anything in any existing
+namespace. The default value for this option is the fully-qualified
+name of the namespace in which the \fBnamespace ensemble create\fR
+command is invoked.
+.PP
+The following extra option is allowed by \fBnamespace ensemble
+configure\fR:
+.TP
+\fB\-namespace\fR
+This read-only option allows the retrieval of the fully-qualified name
+of the namespace which the ensemble was created within.
+.SS "UNKNOWN HANDLER BEHAVIOUR"
+.PP
+If an unknown handler is specified for an ensemble, that handler is
+called when the ensemble command would otherwise return an error due
+to it being unable to decide which subcommand to invoke. The exact
+conditions under which that occurs are controlled by the
+\fB\-subcommands\fR, \fB\-map\fR and \fB\-prefixes\fR options as
+described above.
+.PP
+To execute the unknown handler, the ensemble mechanism takes the
+specified \fB\-unknown\fR option and appends each argument of the
+attempted ensemble command invocation (including the ensemble command
+itself, expressed as a fully qualified name). It invokes the resulting
+command in the scope of the attempted call. If the execution of the
+unknown handler terminates normally, the ensemble engine reparses the
+subcommand (as described below) and tries to dispatch it again, which
+is ideal for when the ensemble's configuration has been updated by the
+unknown subcommand handler. Any other kind of termination of the
+unknown handler is treated as an error.
+.PP
+The result of the unknown handler is expected to be a list (it is an
+error if it is not). If the list is an empty list, the ensemble
+command attempts to look up the original subcommand again and, if it
+is not found this time, an error will be generated just as if the
+\fB\-unknown\fR handler was not there (i.e. for any particular
+invocation of an ensemble, its unknown handler will be called at most
+once.) This makes it easy for the unknown handler to update the
+ensemble or its backing namespace so as to provide an implementation
+of the desired subcommand and reparse.
+.PP
+When the result is a non-empty list, the words of that list are used
+to replace the ensemble command and subcommand, just as if they had
+been looked up in the \fB\-map\fR. It is up to the unknown handler to
+supply all namespace qualifiers if the implementing subcommand is not
+in the namespace of the caller of the ensemble command. Also note that
+when ensemble commands are chained (e.g. if you make one of the
+commands that implement an ensemble subcommand into an ensemble, in a
+manner similar to the \fBtext\fR widget's tag and mark subcommands) then the
+rewrite happens in the context of the caller of the outermost
+ensemble. That is to say that ensembles do not in themselves place any
+namespace contexts on the Tcl call stack.
+.PP
+Where an empty \fB\-unknown\fR handler is given (the default), the
+ensemble command will generate an error message based on the list of
+commands that the ensemble has defined (formatted similarly to the
+error message from \fBTcl_GetIndexFromObj\fR). This is the error that
+will be thrown when the subcommand is still not recognized during
+reparsing. It is also an error for an \fB\-unknown\fR handler to
+delete its namespace.

+.PP
+The \fBplatform\fR package provides several utility commands useful
+for the identification of the architecture of a machine running Tcl.
+.PP
+Whilst Tcl provides the \fBtcl_platform\fR array for identifying the
+current architecture (in particular, the platform and machine
+elements) this is not always sufficient. This is because (on Unix
+machines) \fBtcl_platform\fR reflects the values returned by the
+\fBuname\fR command and these are not standardized across platforms and
+architectures. In addition, on at least one platform (AIX) the
+\fBtcl_platform(machine)\fR contains the CPU serial number.
+.PP
+Consequently, individual applications need to manipulate the values in
+\fBtcl_platform\fR (along with the output of system specific
+utilities) - which is both inconvenient for developers, and introduces
+the potential for inconsistencies in identifying architectures and in
+naming conventions.
+.PP
+The \fBplatform\fR package prevents such fragmentation - i.e., it
+establishes a standard naming convention for architectures running Tcl
+and makes it more convenient for developers to identify the current
+architecture a Tcl program is running on.

+may contain dashes as well. The \fICPU\fR part will not contain

+.TP
+\fBplatform::generic\fR
+This command returns a simplified identifier describing the platform
+the Tcl core is running on. In contrast to \fBplatform::identify\fR it

+.PP
+The \fBplatform::shell\fR package provides several utility commands useful
+for the identification of the architecture of a specific Tcl shell.
+.PP
+This package allows the identification of the architecture of a
+specific Tcl shell different from the shell running the package. The
+only requirement is that the other shell (identified by its path), is
+actually executable on the current machine.
+.PP
+While for most platform this means that the architecture of the
+interrogated shell is identical to the architecture of the running
+shell this is not generally true. A counter example are all platforms
+which have 32 and 64 bit variants and where a 64bit system is able to
+run 32bit code. For these running and interrogated shell may have
+different 32/64 bit settings and thus different identifiers.
+.PP
+For applications like a code repository it is important to identify
+the architecture of the shell which will actually run the installed
+packages, versus the architecture of the shell running the repository
+software.

+refchan \- Command handler API of reflected channels, version 1
+.SH SYNOPSIS
+\fBcmdPrefix \fIoption\fR ?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+The Tcl-level handler for a reflected channel has to be a command with
+subcommands (termed an \fIensemble\fR, as it is a command such as that
+created by \fBnamespace ensemble create\fR, though the implementation
+of handlers for reflected channel \fIis not\fR tied to \fBnamespace
+ensemble\fRs in any way). Note that \fIcmdPrefix\fR is whatever was
+specified in the call to \fBchan create\fR, and may consist of
+multiple arguments; this will be expanded to multiple words in place
+of the prefix.
+.PP
+Of all the possible subcommands, the handler \fImust\fR support
+\fBinitialize\fR, \fBfinalize\fR, and \fBwatch\fR. Support for the
+other subcommands is optional.
+.SS "MANDATORY SUBCOMMANDS"
+.TP
+\fIcmdPrefix \fBinitialize \fIchannelId mode\fR
+.
+An invocation of this subcommand will be the first call the
+\fIcmdPrefix\fR will receive for the specified new \fIchannelId\fR. It
+is the responsibility of this subcommand to set up any internal data
+structures required to keep track of the channel and its state.
+.RS
+.PP
+The return value of the method has to be a list containing the names
+of all subcommands supported by the \fIcmdPrefix\fR. This also tells
+the Tcl core which version of the API for reflected channels is used by
+this command handler.
+.PP
+Any error thrown by the method will abort the creation of the channel
+and no channel will be created. The thrown error will appear as error
+thrown by \fBchan create\fR. Any exception other than an \fBerror\fR
+(e.g. \fBbreak\fR, etc.) is treated as (and converted to) an error.
+.PP
+\fBNote:\fR If the creation of the channel was aborted due to failures
+here, then the \fBfinalize\fR subcommand will not be called.
+.PP
+The \fImode\fR argument tells the handler whether the channel was
+opened for reading, writing, or both. It is a list containing any of
+the strings \fBread\fR or \fBwrite\fR. The list will always
+contain at least one element.
+.PP
+The subcommand must throw an error if the chosen mode is not
+supported by the \fIcmdPrefix\fR.
+.RE
+.TP
+\fIcmdPrefix \fBfinalize \fIchannelId\fR
+.
+An invocation of this subcommand will be the last call the
+\fIcmdPrefix\fR will receive for the specified \fIchannelId\fR. It will
+be generated just before the destruction of the data structures of the
+channel held by the Tcl core. The command handler \fImust not\fR
+access the \fIchannelId\fR anymore in no way. Upon this subcommand being
+called, any internal resources allocated to this channel must be
+cleaned up.
+.RS
+.PP
+The return value of this subcommand is ignored.
+.PP
+If the subcommand throws an error the command which caused its
+invocation (usually \fBclose\fR) will appear to have thrown this
+error. Any exception beyond \fIerror\fR (e.g. \fIbreak\fR, etc.) is
+treated as (and converted to) an error.
+.PP
+This subcommand is not invoked if the creation of the channel was
+aborted during \fBinitialize\fR (See above).
+.RE
+.TP
+\fIcmdPrefix \fBwatch \fIchannelId eventspec\fR
+.
+This subcommand notifies the \fIcmdPrefix\fR that the specified
+\fIchannelId\fR is interested in the events listed in the
+\fIeventspec\fR. This argument is a list containing any of \fBread\fR
+and \fBwrite\fR. The list may be empty, which signals that the
+channel does not wish to be notified of any events. In that situation,
+the handler should disable event generation completely.
+.RS
+.PP
+\fBWarning:\fR Any return value of the subcommand is ignored. This
+includes all errors thrown by the subcommand, break, continue, and
+custom return codes.
+.PP
+This subcommand interacts with \fBchan postevent\fR. Trying to post an
+event which was not listed in the last call to \fBwatch\fR will cause
+\fBchan postevent\fR to throw an error.
+.RE
+.SS "OPTIONAL SUBCOMMANDS"
+.TP
+\fIcmdPrefix \fBread \fIchannelId count\fR
+.
+This \fIoptional\fR subcommand is called when the user requests data from the
+channel \fIchannelId\fR. \fIcount\fR specifies how many \fBbytes\fR have been
+requested. If the subcommand is not supported then it is not possible to read
+from the channel handled by the command.
+.RS
+.PP
+The return value of this subcommand is taken as the requested data
+\fIbytes\fR. If the returned data contains more bytes than requested,
+an error will be signaled and later thrown by the command which
+performed the read (usually \fBgets\fR or \fBread\fR). However,
+returning fewer bytes than requested is acceptable.
+.PP
+Note that returning nothing (0 bytes) is a signal to the higher layers
+that \fBEOF\fR has been reached on the channel. To signal that the
+channel is out of data right now, but has not yet reached \fBEOF\fR,
+it is necessary to throw the error "EAGAIN", i.e. to either
+.PP
+.CS
+return -code error EAGAIN
+.CE
+or
+.CS
+error EAGAIN
+.CE
+.PP
+For extensibility any error whose value is a negative integer number
+will cause the higher layers to set the C-level variable "\fBerrno\fR"
+to the absolute value of this number, signaling a system error. This
+means that both
+.PP
+.CS
+return -code error -11
+.CE
+and
+.CS
+error -11
+.CE
+.PP
+are equivalent to the examples above, using the more readable string "EAGAIN".
+No other error value has such a mapping to a symbolic string.
+.PP
+If the subcommand throws any other error, the command which caused its
+invocation (usually \fBgets\fR, or \fBread\fR) will appear to have
+thrown this error. Any exception beyond \fIerror\fR, (e.g.
+\fIbreak\fR, etc.) is treated as and converted to an error.
+.RE
+.TP
+\fIcmdPrefix \fBwrite \fIchannelId data\fR
+.
+This \fIoptional\fR subcommand is called when the user writes data to
+the channel \fIchannelId\fR. The \fIdata\fR argument contains \fIbytes\fR, not
+characters. Any type of transformation (EOL, encoding) configured for
+the channel has already been applied at this point. If this subcommand
+is not supported then it is not possible to write to the channel
+handled by the command.
+.RS
+.PP
+The return value of the subcommand is taken as the number of bytes
+written by the channel. Anything non-numeric will cause an error to be
+signaled and later thrown by the command which performed the write. A
+negative value implies that the write failed. Returning a value
+greater than the number of bytes given to the handler, or zero, is
+forbidden and will cause the Tcl core to throw an error.
+.PP
+To signal that the channel is not able to accept data for writing
+right now, it is necessary to throw the error "EAGAIN", i.e. to either
+.PP
+.CS
+return -code error EAGAIN
+.CE
+or
+.CS
+error EAGAIN
+.CE
+.PP
+For extensibility any error whose value is a negative integer number
+will cause the higher layers to set the C-level variable "\fBerrno\fR"
+to the absolute value of this number, signaling a system error.
+However, note that the exact mapping between these error numbers and
+their meanings is operating system dependent.
+.PP
+For example, while on Linux both
+.PP
+.CS
+return -code error -11
+.CE
+and
+.CS
+error -11
+.CE
+.PP
+are equivalent to the examples above, using the more readable string "EAGAIN",
+this is not true for BSD, where the equivalent number is -35.
+.PP
+The symbolic string however is the same across systems, and internally
+translated to the correct number. No other error value has such a mapping
+to a symbolic string.
+.PP
+If the subcommand throws any other error the command which caused its
+invocation (usually \fBputs\fR) will appear to have thrown this error.
+Any exception beyond \fIerror\fR (e.g.\ \fIbreak\fR, etc.) is treated
+as and converted to an error.
+.RE
+.TP
+\fIcmdPrefix \fBseek \fIchannelId offset base\fR
+.
+This \fIoptional\fR subcommand is responsible for the handling of
+\fBseek\fR and \fBtell\fR requests on the channel \fIchannelId\fR. If it is not
+supported then seeking will not be possible for the channel.
+.RS
+.PP
+The \fIbase\fR argument is one of
+.TP 10

+Seeking is relative to the beginning of the channel.
+.TP 10
+\fBcurrent\fR
+.
+Seeking is relative to the current seek position.
+.TP 10
+\fBend\fR
+.
+Seeking is relative to the end of the channel.
+.PP
+The \fIbase\fR argument of the builtin \fBchan seek\fR command takes
+the same names.
+.PP
+The \fIoffset\fR is an integer number specifying the amount of
+\fBbytes\fR to seek forward or backward. A positive number should seek
+forward, and a negative number should seek backward.
+.PP
+A channel may provide only limited seeking. For example sockets can
+seek forward, but not backward.
+.PP
+The return value of the subcommand is taken as the (new) location of
+the channel, counted from the start. This has to be an integer number
+greater than or equal to zero.
+.PP
+If the subcommand throws an error the command which caused its
+invocation (usually \fBseek\fR, or \fBtell\fR) will appear to have
+thrown this error. Any exception beyond \fIerror\fR (e.g. \fIbreak\fR,
+etc.) is treated as and converted to an error.
+.PP
+The offset/base combination of 0/\fBcurrent\fR signals a \fBtell\fR
+request, i.e. seek nothing relative to the current location, making
+the new location identical to the current one, which is then returned.
+.RE
+.TP
+\fIcmdPrefix \fBconfigure \fIchannelId option value\fR
+.
+This \fIoptional\fR subcommand is for setting the type-specific options of
+channel \fIchannelId\fR. The \fIoption\fR argument indicates the option to be
+written, and the \fIvalue\fR argument indicates the value to set the option to.
+.RS
+.PP
+This subcommand will never try to update more than one option at a
+time; that is behavior implemented in the Tcl channel core.
+.PP
+The return value of the subcommand is ignored.
+.PP
+If the subcommand throws an error the command which performed the
+(re)configuration or query (usually \fBfconfigure\fR or \fBchan

+option of channel \fIchannelId\fR. If this subcommand is supported then the
+subcommand \fBcgetall\fR must be supported as well.

+This \fIoptional\fR subcommand handles changes to the blocking mode of the

+.PP
+The function \fBTcl_DriverHandlerProc\fR is not supported. This driver
+function is relevant only for stacked channels, i.e. transformations.
+Reflected channels are always base channels, not transformations.
+.PP
+The function \fBTcl_DriverFlushProc\fR is not supported. This is
+because the current generic I/O layer of Tcl does not use this
+function anywhere at all. Therefore support at the Tcl level makes no

-.BE
-
-.SH DESCRIPTION
-.PP
-The \fBresource\fR command provides some generic operations for
-dealing with Macintosh resources. This command is only supported on
-the Macintosh platform. Each Macintosh file consists of two
-\fIforks\fR: a \fIdata\fR fork and a \fIresource\fR fork. You use the
-normal open, puts, close, etc. commands to manipulate the data fork.
-You must use this command, however, to interact with the resource
-fork. \fIOption\fR indicates what resource command to perform. Any
-unique abbreviation for \fIoption\fR is acceptable. The valid options
-are:
-.TP
-\fBresource close \fIrsrcRef\fR
-Closes the given resource reference (obtained from \fBresource
-open\fR). Resources from that resource file will no longer be
-available.
-.TP
-\fBresource delete\fR ?\fIoptions\fR? \fIresourceType\fR
-This command will delete the resource specified by \fIoptions\fR and
-type \fIresourceType\fR (see RESOURCE TYPES below). The options
-give you several ways to specify the resource to be deleted.
-.RS
-.TP
-\fB\-id\fR \fIresourceId\fR
-If the \fB-id\fR option is given the id \fIresourceId\fR (see RESOURCE
-IDS below) is used to specify the resource to be deleted. The id must
-be a number - to specify a name use the \fB\-name\fR option.
-.TP
-\fB\-name\fR \fIresourceName\fR
-If \fB-name\fR is specified, the resource named
-\fIresourceName\fR will be deleted. If the \fB-id\fR is also
-provided, then there must be a resource with BOTH this name and
-this id. If no name is provided, then the id will be used regardless
-of the name of the actual resource.
-.TP
-\fB\-file\fR \fIresourceRef\fR
-If the \fB-file\fR option is specified then the resource will be
-deleted from the file pointed to by \fIresourceRef\fR. Otherwise the
-first resource with the given \fIresourceName\fR and or
-\fIresourceId\fR which is found on the resource file path will be
-deleted. To inspect the file path, use the \fIresource files\fR command.
-.RE

-\fBresource files ?\fIresourceRef\fR?
-If \fIresourceRef\fRis not provided, this command returns a Tcl list
-of the resource references for all the currently open resource files.
-The list is in the normal Macintosh search order for resources. If
-\fIresourceRef\fR is specified, the command will
-return the path to the file whose resource fork is represented by that
-token.

-\fBresource list \fIresourceType\fR ?\fIresourceRef\fR?
-List all of the resources ids of type \fIresourceType\fR (see RESOURCE

-limit the search to that particular resource file. Otherwise, all
-resource files currently opened by the application will be searched.
-A Tcl list of either the resource name's or resource id's of the found

-\fBresource open \fIfileName\fR ?\fIaccess\fR?
-Open the resource for the file \fIfileName\fR. Standard file access
-permissions may also be specified (see the manual entry for \fBopen\fR
-for details). A resource reference (\fIresourceRef\fR) is returned
-that can be used by the other resource commands. An error can occur
-if the file doesn't exist or the file does not have a resource fork.
-However, if you open the file with write permissions the file and/or

+becomes the result of the procedure passed back to the caller.
+If \fIresult\fR is not specified then an empty string will be returned
+to the caller as the result of the procedure.
+.PP
+The \fBreturn\fR command serves a similar function within script
+files that are evaluated by the \fBsource\fR command. When \fBsource\fR
+evaluates the contents of a file as a script, an invocation of
+the \fBreturn\fR command will cause script evaluation
+to immediately cease, and the value \fIresult\fR (or an empty string)

-may be used to provide additional information during error

-These options are ignored unless \fIcode\fR is \fBerror\fR.

-The \fB\-errorinfo\fR option specifies an initial stack

+.VE 8.5
+.PP
+As documented above, the \fB\-code\fR entry in the return options dictionary
+receives special treatment by Tcl. There are other return options also
+recognized and treated specially by Tcl. They are:
+.TP
+\fB\-errorcode \fIlist\fR
+The \fB\-errorcode\fR option receives special treatment only when the value
+of the \fB\-code\fR option is \fBTCL_ERROR\fR. Then the \fIlist\fR value
+is meant to be additional information about the error,
+presented as a Tcl list for further processing by programs.
+If no \fB\-errorcode\fR option is provided to \fBreturn\fR when
+the \fB\-code error\fR option is provided, Tcl will set the value
+of the \fB\-errorcode\fR entry in the return options dictionary
+to the default value of \fBNONE\fR. The \fB\-errorcode\fR return
+option will also be stored in the global variable \fBerrorCode\fR.
+.TP
+\fB\-errorinfo \fIinfo\fR
+The \fB\-errorinfo\fR option receives special treatment only when the value
+of the \fB\-code\fR option is \fBTCL_ERROR\fR. Then \fIinfo\fR is the initial
+stack trace, meant to provide to a human reader additional information
+about the context in which the error occurred. The stack trace will
+also be stored in the global variable \fBerrorInfo\fR.
+If no \fB\-errorinfo\fR option is provided to \fBreturn\fR when
+the \fB\-code error\fR option is provided, Tcl will provide its own
+initial stack trace value in the entry for \fB\-errorinfo\fR. Tcl's
+initial stack trace will include only the call to the procedure, and
+stack unwinding will append information about higher stack levels, but
+there will be no information about the context of the error within
+the procedure. Typically the \fIinfo\fR value is supplied from
+the value of \fB\-errorinfo\fR in a return options dictionary captured
+by the \fBcatch\fR command (or from the copy of that information
+stored in the global variable \fBerrorInfo\fR).
+.TP
+\fB\-level \fIlevel\fR
+.VS 8.5
+The \fB\-level\fR and \fB\-code\fR options work together to set the return
+code to be returned by one of the commands currently being evaluated.
+The \fIlevel\fR value must be a non-negative integer representing a number
+of levels on the call stack. It defines the number of levels up the stack
+at which the return code of a command currently being evaluated should
+be \fIcode\fR. If no \fB\-level\fR option is provided, the default value
+of \fIlevel\fR is 1, so that \fBreturn\fR sets the return code that the
+current procedure returns to its caller, 1 level up the call stack. The
+mechanism by which these options work is described in more detail below.
+.VE 8.5

+\fB\-options \fIoptions\fR

+The value \fIoptions\fR must be a valid dictionary. The entries of that
+dictionary are treated as additional \fIoption value\fR pairs for the
+\fBreturn\fR command.
+.VE 8.5
+.SH "RETURN CODE HANDLING MECHANISMS"
+.PP
+Return codes are used in Tcl to control program flow. A Tcl script
+is a sequence of Tcl commands. So long as each command evaluation
+returns a return code of \fBTCL_OK\fR, evaluation will continue to the next
+command in the script. Any exceptional return code (non-\fBTCL_OK\fR)
+returned by a command evaluation causes the flow on to the next
+command to be interrupted. Script evaluation ceases, and the
+exceptional return code from the command becomes the return code
+of the full script evaluation. This is the mechanism by which
+errors during script evaluation cause an interruption and unwinding
+of the call stack. It is also the mechanism by which commands
+like \fBbreak\fR, \fBcontinue\fR, and \fBreturn\fR cause script
+evaluation to terminate without evaluating all commands in sequence.
+.PP
+Some of Tcl's built-in commands evaluate scripts as part of their
+functioning. These commands can make use of exceptional return
+codes to enable special features. For example, the built-in
+Tcl commands that provide loops \(em such as \fBwhile\fR, \fBfor\fR,
+and \fBforeach\fR \(em evaluate a script that is the body of the
+loop. If evaluation of the loop body returns the return code
+of \fBTCL_BREAK\fR or \fBTCL_CONTINUE\fR, the loop command can react in such
+a way as to give the \fBbreak\fR and \fBcontinue\fR commands
+their documented interpretation in loops.
+.PP
+.VS 8.5
+Procedure invocation also involves evaluation of a script, the body
+of the procedure. Procedure invocation provides special treatment
+when evaluation of the procedure body returns the return code
+\fBTCL_RETURN\fR. In that circumstance, the \fB\-level\fR entry in the
+return options dictionary is decremented. If after decrementing,
+the value of the \fB\-level\fR entry is 0, then the value of
+the \fB\-code\fR entry becomes the return code of the procedure.
+If after decrementing, the value of the \fB\-level\fR entry is
+greater than zero, then the return code of the procedure is
+\fBTCL_RETURN\fR. If the procedure invocation occurred during the
+evaluation of the body of another procedure, the process will
+repeat itself up the call stack, decrementing the value of the
+\fB\-level\fR entry at each level, so that the \fIcode\fR will
+be the return code of the current command \fIlevel\fR levels
+up the call stack. The \fBsource\fR command performs the
+same handling of the \fBTCL_RETURN\fR return code, which explains
+the similarity of \fBreturn\fR invocation during a \fBsource\fR
+to \fBreturn\fR invocation within a procedure.
+.PP
+The return code of the \fBreturn\fR command itself triggers this
+special handling by procedure invocation. If \fBreturn\fR
+is provided the option \fB\-level 0\fR, then the return code
+of the \fBreturn\fR command itself will be the value \fIcode\fR
+of the \fB\-code\fR option (or \fBTCL_OK\fR by default). Any other value
+for the \fB\-level\fR option (including the default value of 1)
+will cause the return code of the \fBreturn\fR command itself
+to be \fBTCL_RETURN\fR, triggering a return from the enclosing procedure.

+This document describes the facilities for locating and loading Tcl

+The following commands are supported:
+.TP
+\fB::tcl::tm::path add \fR?\fIpath\fR...?
+.
+The paths are added at the head to the list of module paths, in order
+of appearance. This means that the last argument ends up as the new

+.RS
+.PP
+The command enforces the restriction that no path may be an ancestor
+directory of any other path on the list. If any of the new paths
+violates this restriction an error will be raised, before any of the
+paths have been added. In other words, if only one path argument
+violates the restriction then none will be added.
+.PP
+If a path is already present as is, no error will be raised and no
+action will be taken.
+.PP
+Paths are searched later in the order of their appearance in the

+reverse order of addition. In other words, the paths added last are
+looked at first.

+.SH "MODULE DEFINITION"
+A Tcl Module is a Tcl Package contained in a single file, and no other
+files required by it. This file has to be \fBsource\fRable. In other
+words, a Tcl Module is always imported via:
+.CS
+source module_file
+.CE
+.PP
+The \fBload\fR command is not directly used. This restriction is not
+an actual limitation, as some may believe.
+Ever since 8.4 the Tcl \fBsource\fR command reads only until the first
+^Z character. This allows us to combine an arbitrary Tcl script with
+arbitrary binary data into one file, where the script processes the
+attached data in any it chooses to fully import and activate the
+package.
+.PP
+The name of a module file has to match the regular expression:
+.CS
+([_[:alpha:]][:_[:alnum:]]*)-([[:digit:]].*)\e.tm
+.CE
+.PP
+The first capturing parentheses provides the name of the package, the
+second clause its version. In addition to matching the pattern, the
+extracted version number must not raise an error when used in the
+command:
+.CS
+package vcompare $version 0
+.CE
+.PP
+.SH "FINDING MODULES"
+The directory tree for storing Tcl modules is separate from other
+parts of the filesystem and independent of \fBauto_path\fR.
+.PP
+Tcl Modules are searched for in all directories listed in the result
+of the command \fB::tcl::tm::path list\fR.
+This is called the \fIModule path\fR. Neither the \fBauto_path\fR nor
+the \fBtcl_pkgPath\fR variables are used.
+All directories on the module path have to obey one restriction:
+.RS
+.PP
+For any two directories, neither is an ancestor directory of the
+other.
+.RE
+.PP
+This is required to avoid ambiguities in package naming. If for
+example the two directories
+.QW "\fIfoo/\fR"
+and
+.QW "\fIfoo/cool\fR"
+were on
+the path a package named \fBcool::ice\fR could be found via the
+names \fBcool::ice\fR or \fBice\fR, the latter potentially
+obscuring a package named \fBice\fR, unqualified.
+.PP
+Before the search is started, the name of the requested package is
+translated into a partial path, using the following algorithm:
+.RS
+.PP
+All occurrences of
+.QW "\fB::\fR"
+in the package name are replaced by
+the appropriate directory separator character for the platform we are
+on. On Unix, for example, this is
+.QW "\fB/\fR" .
+.RE
+.PP
+Example:
+.RS
+.PP
+The requested package is \fBencoding::base64\fR. The generated
+partial path is
+.QW "\fIencoding/base64\fR" .
+.RE
+.PP
+After this translation the package is looked for in all module paths,
+by combining them one-by-one, first to last with the partial path to
+form a complete search pattern. Note that the search algorithm rejects
+all files where the filename does not match the regular expression
+given in the section \fBMODULE DEFINITION\fR. For the remaining
+files \fIprovide scripts\fR are generated and added to the package
+ifneeded database.
+.PP
+The algorithm falls back to the previous unknown handler when none of
+the found module files satisfy the request. If the request was
+satisfied the fall-back is ignored.
+.PP
+Note that packages in module form have \fIno\fR control over the
+\fIindex\fR and \fIprovide script\fRs entered into the package
+database for them.
+For a module file \fBMF\fR the \fIindex script\fR is always:
+.CS
+package ifneeded \fBPNAME PVERSION\fR [list source \fBMF\fR]
+.CE
+and the \fIprovide script\fR embedded in the above is:
+.CS
+source \fBMF\fR
+.CE
+.PP
+Both package name \fBPNAME\fR and package version \fBPVERSION\fR are
+extracted from the filename \fBMF\fR according to the definition
+below:
+.CS
+\fBMF\fR = /module_path/\fBPNAME\(fm\fR-\fBPVERSION\fR.tm
+.CE
+.PP
+Where \fBPNAME\(fm\fR is the partial path of the module as defined in
+section \fBFINDING MODULES\fR, and translated into \fBPNAME\fR by
+changing all directory separators to
+.QW "\fB::\fR" ,
+and \fBmodule_path\fR is the path (from the list of paths to search)
+that we found the module file under.
+.PP
+Note also that we are here creating a connection between package names
+and paths. Tcl is case-sensitive when it comes to comparing package
+names, but there are filesystems which are not, like NTFS. Luckily
+these filesystems do store the case of the name, despite not using the
+information when comparing.
+.PP
+Given the above we allow the names for packages in Tcl modules to have
+mixed-case, but also require that there are no collisions when
+comparing names in a case-insensitive manner. In other words, if a
+package \fBFoo\fR is deployed in the form of a Tcl Module,
+packages like \fBfoo\fR, \fBfOo\fR, etc. are not allowed
+anymore.
+.SH "DEFAULT PATHS"
+The default list of paths on the module path is computed by a
+\fBtclsh\fR as follows, where \fIX\fR is the major version of the Tcl
+interpreter and \fIy\fR is less than or equal to the minor version of
+the Tcl interpreter.
+.PP
+All the default paths are added to the module path, even those paths
+which do not exist. Non-existent paths are filtered out during actual
+searches. This enables a user to create one of the paths searched when
+needed and all running applications will automatically pick up any
+modules placed in them.
+.PP
+The paths are added in the order as they are listed below, and for
+lists of paths defined by an environment variable in the order they

+.br
+\fBunload \fR?\fIswitches\fR? \fIfileName packageName\fR
+.br
+\fBunload \fR?\fIswitches\fR? \fIfileName packageName interp\fR
+.BE
+.SH DESCRIPTION
+.PP
+This command tries to unload shared libraries previously loaded
+with \fBload\fR from the application's address space. \fIfileName\fR
+is the name of the file containing the library file to be unload; it
+must be the same as the filename provided to \fBload\fR for
+loading the library.
+The \fIpackageName\fR argument is the name of the package (as
+determined by or passed to \fBload\fR), and is used to
+compute the name of the unload procedure; if not supplied, it is
+computed from \fIfileName\fR in the same manner as \fBload\fR.
+The \fIinterp\fR argument is the path name of the interpreter from
+which to unload the package (see the \fBinterp\fR manual entry for
+details); if \fIinterp\fR is omitted, it defaults to the
+interpreter in which the \fBunload\fR command was invoked.
+.PP
+If the initial arguments to \fBunload\fR start with \fB\-\fR then
+they are treated as switches. The following switches are
+currently supported:
+.TP
+\fB\-nocomplain\fR
+.
+Suppresses all error messages. If this switch is given, \fBunload\fR will
+never report an error.
+.TP
+\fB\-keeplibrary\fR
+.
+This switch will prevent \fBunload\fR from issuing the operating system call
+that will unload the library from the process.
+.TP
+\fB\-\|\-\fR
+.
+Marks the end of switches. The argument following this one will
+be treated as a \fIfileName\fR even if it starts with a \fB\-\fR.
+.SS "UNLOAD OPERATION"
+.PP
+When a file containing a shared library is loaded through the
+\fBload\fR command, Tcl associates two reference counts to the library
+file. The first counter shows how many times the library has been
+loaded into normal (trusted) interpreters while the second describes how many
+times the library has been loaded into safe interpreters. As a file containing
+a shared library can be loaded only once by Tcl (with the first \fBload\fR
+call on the file), these counters track how many interpreters use the library.
+Each subsequent call to \fBload\fR after the first simply increments the
+proper reference count.
+.PP
+\fBunload\fR works in the opposite direction. As a first step, \fBunload\fR
+will check whether the library is unloadable: an unloadable library exports
+a special unload procedure. The name of the unload procedure is determined by
+\fIpackageName\fR and whether or not the target interpreter
+is a safe one. For normal interpreters the name of the initialization
+procedure will have the form \fIpkg\fB_Unload\fR, where \fIpkg\fR
+is the same as \fIpackageName\fR except that the first letter is
+converted to upper case and all other letters
+are converted to lower case. For example, if \fIpackageName\fR is
+\fBfoo\fR or \fBFOo\fR, the initialization procedure's name will
+be \fBFoo_Unload\fR.
+If the target interpreter is a safe interpreter, then the name
+of the initialization procedure will be \fIpkg\fB_SafeUnload\fR
+instead of \fIpkg\fB_Unload\fR.
+.PP
+If \fBunload\fR determines that a library is not unloadable (or unload
+functionality has been disabled during compilation), an error will be returned.
+If the library is unloadable, then \fBunload\fR will call the unload
+procedure. If the unload procedure returns \fBTCL_OK\fR, \fBunload\fR will proceed
+and decrease the proper reference count (depending on the target interpreter
+type). When both reference counts have reached 0, the library will be
+detached from the process.
+.SS "UNLOAD HOOK PROTOTYPE"
+.PP
+The unload procedure must match the following prototype:
+.CS
+typedef int Tcl_PackageUnloadProc(Tcl_Interp *\fIinterp\fR, int \fIflags\fR);
+.CE
+.PP
+The \fIinterp\fR argument identifies the interpreter from which the
+library is to be unloaded. The unload procedure must return
+\fBTCL_OK\fR or \fBTCL_ERROR\fR to indicate whether or not it completed
+successfully; in the event of an error it should set the interpreter's result
+to point to an error message. In this case, the result of the
+\fBunload\fR command will be the result returned by the unload procedure.
+.PP
+The \fIflags\fR argument can be either \fBTCL_UNLOAD_DETACH_FROM_INTERPRETER\fR
+or \fBTCL_UNLOAD_DETACH_FROM_PROCESS\fR. In case the library will remain
+attached to the process after the unload procedure returns (i.e. because
+the library is used by other interpreters),
+\fBTCL_UNLOAD_DETACH_FROM_INTERPRETER\fR will be defined. However, if the
+library is used only by the target interpreter and the library will be
+detached from the application as soon as the unload procedure returns,
+the \fIflags\fR argument will be set to \fBTCL_UNLOAD_DETACH_FROM_PROCESS\fR.
+.SS NOTES
+.PP
+The \fBunload\fR command cannot unload libraries that are statically
+linked with the application.
+If \fIfileName\fR is an empty string, then the \fIpackageName\fR argument must
+be specified.
+.PP
+If \fIpackageName\fR is omitted or specified as an empty string,
+Tcl tries to guess the name of the package.
+This may be done differently on different platforms.
+The default guess, which is used on most UNIX platforms, is to
+take the last element of \fIfileName\fR, strip off the first
+three characters if they are \fBlib\fR, and use any following
+alphabetic and underline characters as the module name.
+For example, the command \fBunload libxyz4.2.so\fR uses the module
+name \fBxyz\fR and the command \fBunload bin/last.so {}\fR uses the
+module name \fBlast\fR.
+.SH "PORTABILITY ISSUES"
+.TP
+\fBUnix\fR\0\0\0\0\0
+.
+Not all unix operating systems support library unloading. Under such
+an operating system \fBunload\fR returns an error (unless \fB\-nocomplain\fR
+has been specified).
+.SH BUGS
+.PP
+If the same file is \fBload\fRed by different \fIfileName\fRs, it will
+be loaded into the process's address space multiple times. The
+behavior of this varies from system to system (some systems may
+detect the redundant loads, others may not). In case a library has been
+silently detached by the operating system (and as a result Tcl thinks the
+library is still loaded), it may be dangerous to use
+\fBunload\fR on such a library (as the library will be completely detached
+from the application while some interpreters will continue to use it).
+.SH EXAMPLE
+If an unloadable module in the file \fBfoobar.dll\fR had been loaded
+using the \fBload\fR command like this (on Windows):
+.CS
+load c:/some/dir/foobar.dll
+.CE
+then it would be unloaded like this:
+.CS
+\fBunload\fR c:/some/dir/foobar.dll
+.CE
+.PP
+This allows a C code module to be installed temporarily into a
+long-running Tcl program and then removed again (either because it is
+no longer needed or because it is being updated with a new version)
+without having to shut down the overall Tcl process.

- * The 'clientData' and 'interp' arguments to 'proc' will be the
- * same as the arguments to Tcl_CreateObjTrace. The 'level'
- * argument gives the nesting depth of command interpretation within
- * the interpreter. The 'command' argument is the ASCII text of
- * the command being evaluated -- before any substitutions are
- * performed. The 'commandInfo' argument gives a handle to the
- * command procedure that will be evaluated. The 'objc' and 'objv'
- * parameters give the parameter vector that will be passed to the
- * command procedure. proc does not return a value.
- *
- * It is permissible for 'proc' to call Tcl_SetCommandTokenInfo
- * to change the command procedure or client data for the command
- * being evaluated, and these changes will take effect with the
- * current evaluation.
- *
- * The 'level' argument specifies the maximum nesting level of calls

- * 'level', the trace callback is not executed.
- *
- * The 'flags' argument is either zero or the value,
- * TCL_ALLOW_INLINE_COMPILATION. If the TCL_ALLOW_INLINE_COMPILATION
- * flag is not present, the bytecode compiler will not generate inline
- * code for Tcl's built-in commands. This behavior will have a significant

- * code for some of Tcl's built-in commands. In this case, the tracing
- * will be imprecise -- in-line code will not be traced -- but run-time
- * performance will be improved. The latter behavior is desired for

*
- * This procedure compiles a string containing a Tcl expression into
- * Tcl bytecodes. This procedure is the top-level interface to the
- * the expression compilation module, and is used by such public
- * procedures as Tcl_ExprString, Tcl_ExprStringObj, Tcl_ExprLong,
- * Tcl_ExprDouble, Tcl_ExprBoolean, and Tcl_ExprBooleanObj.
+ * Given a string, the numBytes bytes starting at start, this function
+ * parses it as a Tcl expression and constructs a tree representing
+ * the structure of the expression. The caller must pass in empty
+ * lists as the funcList and litList arguments. The elements of the
+ * parsed expression are returned to the caller as that tree, a list of
+ * literal values, a list of function names, and in Tcl_Tokens
+ * added to a Tcl_Parse struct passed in by the caller.
*
* Results:
- * The return value is TCL_OK on a successful compilation and TCL_ERROR
- * on failure. If TCL_ERROR is returned, then the interpreter's result
- * contains an error message.
+ * If the string is successfully parsed as a valid Tcl expression, TCL_OK
+ * is returned, and data about the expression structure is written to
+ * the last four arguments. If the string cannot be parsed as a valid
+ * Tcl expression, TCL_ERROR is returned, and if interp is non-NULL, an
+ * error message is written to interp.
*
* Side effects:
- * Adds instructions to envPtr to evaluate the expression at runtime.
+ * Memory will be allocated. If TCL_OK is returned, the caller must
+ * clean up the returned data structures. The (OpNode *) value written
+ * to opTreePtr should be passed to ckfree() and the parsePtr argument
+ * should be passed to Tcl_FreeParse(). The elements appended to the
+ * litList and funcList will automatically be freed whenever the
+ * refcount on those lists indicates they can be freed.

- * Tcl_ParseExpr --
- *
- * Given a string, this procedure parses the first Tcl expression
- * in the string and returns information about the structure of
- * the expression. This procedure is the top-level interface to the
- * the expression parsing module. No more that numBytes bytes will
- * be scanned.
- *
- * Results:
- * The return value is TCL_OK if the command was parsed successfully
- * and TCL_ERROR otherwise. If an error occurs and interp isn't NULL
- * then an error message is left in its result. On a successful return,
- * parsePtr is filled in with information about the expression that
- * was parsed.
- *
- * Side effects:
- * If there is insufficient space in parsePtr to hold all the
- * information about the expression, then additional space is
- * malloc-ed. If the procedure returns TCL_OK then the caller must
- * eventually invoke Tcl_FreeParse to release any additional space
- * that was allocated.

+ *
+ * TclParseNumber --
+ *
+ * Scans bytes, interpreted as characters in Tcl's internal encoding, and
+ * parses the longest prefix that is the string representation of a
+ * number in a format recognized by Tcl.
+ *
+ * The arguments bytes, numBytes, and objPtr are the inputs which
+ * determine the string to be parsed. If bytes is non-NULL, it points to
+ * the first byte to be scanned. If bytes is NULL, then objPtr must be
+ * non-NULL, and the string representation of objPtr will be scanned
+ * (generated first, if necessary). The numBytes argument determines the
+ * number of bytes to be scanned. If numBytes is negative, the first NUL
+ * byte encountered will terminate the scan. If numBytes is non-negative,
+ * then no more than numBytes bytes will be scanned.
+ *
+ * The argument flags is an input that controls the numeric formats
+ * recognized by the parser. The flag bits are:
+ *
+ * - TCL_PARSE_INTEGER_ONLY: accept only integer values; reject
+ * strings that denote floating point values (or accept only the
+ * leading portion of them that are integer values).
+ * - TCL_PARSE_SCAN_PREFIXES: ignore the prefixes 0b and 0o that are
+ * not part of the [scan] command's vocabulary. Use only in
+ * combination with TCL_PARSE_INTEGER_ONLY.
+ * - TCL_PARSE_OCTAL_ONLY: parse only in the octal format, whether
+ * or not a prefix is present that would lead to octal parsing.
+ * Use only in combination with TCL_PARSE_INTEGER_ONLY.
+ * - TCL_PARSE_HEXADECIMAL_ONLY: parse only in the hexadecimal format,
+ * whether or not a prefix is present that would lead to
+ * hexadecimal parsing. Use only in combination with
+ * TCL_PARSE_INTEGER_ONLY.
+ * - TCL_PARSE_DECIMAL_ONLY: parse only in the decimal format, no
+ * matter whether a 0 prefix would normally force a different
+ * base.
+ * - TCL_PARSE_NO_WHITESPACE: reject any leading/trailing whitespace
+ *
+ * The arguments interp and expected are inputs that control error
+ * message generation. If interp is NULL, no error message will be
+ * generated. If interp is non-NULL, then expected must also be non-NULL.
+ * When TCL_ERROR is returned, an error message will be left in the
+ * result of interp, and the expected argument will appear in the error
+ * message as the thing TclParseNumber expected, but failed to find in
+ * the string.
+ *
+ * The arguments objPtr and endPtrPtr as well as the return code are the
+ * outputs.
+ *
+ * When the parser cannot find any prefix of the string that matches a
+ * format it is looking for, TCL_ERROR is returned and an error message
+ * may be generated and returned as described above. The contents of
+ * objPtr will not be changed. If endPtrPtr is non-NULL, a pointer to the
+ * character in the string that terminated the scan will be written to
+ * *endPtrPtr.
+ *
+ * When the parser determines that the entire string matches a format it
+ * is looking for, TCL_OK is returned, and if objPtr is non-NULL, then
+ * the internal rep and Tcl_ObjType of objPtr are set to the "canonical"
+ * numeric value that matches the scanned string. If endPtrPtr is not
+ * NULL, a pointer to the end of the string will be written to *endPtrPtr
+ * (that is, either bytes+numBytes or a pointer to a terminating NUL
+ * byte).
+ *
+ * When the parser determines that a partial string matches a format it
+ * is looking for, the value of endPtrPtr determines what happens:
+ *
+ * - If endPtrPtr is NULL, then TCL_ERROR is returned, with error message
+ * generation as above.
+ *
+ * - If endPtrPtr is non-NULL, then TCL_OK is returned and objPtr
+ * internals are set as above. Also, a pointer to the first
+ * character following the parsed numeric string is written to
+ * *endPtrPtr.
+ *
+ * In some cases where the string being scanned is the string rep of
+ * objPtr, this routine can leave objPtr in an inconsistent state where
+ * its string rep and its internal rep do not agree. In these cases the
+ * internal rep will be in agreement with only some substring of the
+ * string rep. This might happen if the caller passes in a non-NULL bytes
+ * value that points somewhere into the string rep. It might happen if
+ * the caller passes in a numBytes value that limits the scan to only a
+ * prefix of the string rep. Or it might happen if a non-NULL value of
+ * endPtrPtr permits a TCL_OK return from only a partial string match. It
+ * is the responsibility of the caller to detect and correct such
+ * inconsistencies when they can and do arise.
+ *
+ * Results:
+ * Returns a standard Tcl result.
+ *
+ * Side effects:
+ * The string representaton of objPtr may be generated.
+ *
+ * The internal representation and Tcl_ObjType of objPtr may be changed.
+ * This may involve allocation and/or freeing of memory.

+ * This function is a service routine that produces the string of digits

+ * TCL_DD_SHORTEST - This is the default for floating point conversion
+ * if ::tcl_precision is 0. It constructs the shortest string
+ * of digits that will reconvert to the given number when scanned.
+ * For floating point numbers that are exactly between two
+ * decimal numbers, it resolves using the 'round to even' rule.
+ * With this value, the 'ndigits' parameter is ignored.
+ * TCL_DD_STEELE - This value is not recommended and may be removed
+ * in the future. It follows the conversion algorithm outlined
+ * in "How to Print Floating-Point Numbers Accurately" by
+ * Guy L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90,
+ * pp. 112-126]. This rule has the effect of rendering 1e23
+ * as 9.9999999999999999e22 - which is a 'better' approximation
+ * in the sense that it will reconvert correctly even if
+ * a subsequent input conversion is 'round up' or 'round down'
+ * rather than 'round to nearest', but is surprising otherwise.
+ * TCL_DD_E_FORMAT - This value is used to prepare numbers for %e
+ * format conversion (or for default floating->string if
+ * tcl_precision is not 0). It constructs a string of at most
+ * 'ndigits' digits, choosing the one that is closest to the
+ * given number (and resolving ties with 'round to even').
+ * It is allowed to return fewer than 'ndigits' if the number
+ * converts exactly; if the TCL_DD_E_FORMAT|TCL_DD_SHORTEN_FLAG
+ * is supplied instead, it also returns fewer digits if the
+ * shorter string will still reconvert to the given input number.
+ * In any case, strings of trailing zeroes are suppressed.
+ * TCL_DD_F_FORMAT - This value is used to prepare numbers for %f
+ * format conversion. It requests that conversion proceed until
+ * 'ndigits' digits after the decimal point have been converted.
+ * It is possible for this format to result in a zero-length
+ * string if the number is sufficiently small. Again, it
+ * is permissible for TCL_DD_F_FORMAT to return fewer digits
+ * for a number that converts exactly, and changing the
+ * argument to TCL_DD_F_FORMAT|TCL_DD_SHORTEN_FLAG will allow
+ * the routine also to return fewer digits if the shorter string
+ * will still reconvert without loss to the given input number.
+ * Strings of trailing zeroes are suppressed.
+ *
+ * To any of these flags may be OR'ed TCL_DD_NO_QUICK; this flag
+ * requires all calculations to be done in exact arithmetic. Normally,
+ * E and F format with fewer than about 14 digits will be done with
+ * a quick floating point approximation and fall back on the exact
+ * arithmetic only if the input number is close enough to the
+ * midpoint between two decimal strings that more precision is needed
+ * to resolve which string is correct.
+ *
+ * The value stored in the 'decpt' argument on return may be negative
+ * (indicating that the decimal point falls to the left of the string)
+ * or greater than the length of the string. In addition, the value -9999
+ * is used as a sentinel to indicate that the string is one of the special
+ * values "Infinity" and "NaN", and that no decimal point should be inserted.

-#
-# Parameters:

-#
-# Results:
-# The "ld" command is parsed, and the "-o" option determines the
-# module name. ".a" and ".o" options are accumulated.
-# The input archives and object files are examined with the "nm"
-# command to determine whether the modules initialization
-# entry and safe initialization entry are present. A trivial
-# C function that locates the entries is composed, compiled, and
-# its .o file placed before all others in the command; then
-# "ld" is executed to bind the objects together.

+# - The only way we get back to the same directory is if someone is
+# trying to [package require] something that wasn't there on the
+# first scan.
+#
+# Either
+# 1) It is there now: If we rescan, you get it; if not you don't.
+#
+# This covers the possibility that the application asked for a
+# package late, and the package was actually added to the
+# installation after the application was started. It shoukld
+# still be able to find it.
+#
+# 2) It still is not there: Either way, you don't get it, but the
+# rescan takes time. This is however an error case and we dont't
+# care that much about it
+#
+# 3) It was there the first time; but for some reason a "package
+# forget" has been run, and "package" doesn't know about it
+# anymore.
+#
+# This can be an indication that the application wishes to reload
+# some functionality. And should work as well.
+#
+# Note that this also strikes a balance between doing a glob targeting
+# a single package, and thus most likely requiring multiple globs of
+# the same directory when the application is asking for many packages,
+# and trying to glob for _everything_ in all subdirectories when
+# looking for a package, which comes with a heavy startup cost.
+#
+# We scan for regular packages only if no satisfying module was found.

+\chapter{Introduction}
+\section{What is LibTomMath?}
+LibTomMath is a library of source code which provides a series of efficient and carefully written functions for manipulating
+large integer numbers. It was written in portable ISO C source code so that it will build on any platform with a conforming
+C compiler.
+
+In a nutshell the library was written from scratch with verbose comments to help instruct computer science students how
+to implement ``bignum'' math. However, the resulting code has proven to be very useful. It has been used by numerous
+universities, commercial and open source software developers. It has been used on a variety of platforms ranging from
+Linux and Windows based x86 to ARM based Gameboys and PPC based MacOS machines.
+
+\section{License}
+As of the v0.25 the library source code has been placed in the public domain with every new release. As of the v0.28
+release the textbook ``Implementing Multiple Precision Arithmetic'' has been placed in the public domain with every new
+release as well. This textbook is meant to compliment the project by providing a more solid walkthrough of the development
+algorithms used in the library.
+
+Since both\footnote{Note that the MPI files under mtest/ are copyrighted by Michael Fromberger. They are not required to use LibTomMath.} are in the
+public domain everyone is entitled to do with them as they see fit.
+
+\section{Building LibTomMath}
+
+LibTomMath is meant to be very ``GCC friendly'' as it comes with a makefile well suited for GCC. However, the library will
+also build in MSVC, Borland C out of the box. For any other ISO C compiler a makefile will have to be made by the end
+developer.
+
+\subsection{Static Libraries}
+To build as a static library for GCC issue the following
+\begin{alltt}
+make
+\end{alltt}
+
+command. This will build the library and archive the object files in ``libtommath.a''. Now you link against
+that and include ``tommath.h'' within your programs. Alternatively to build with MSVC issue the following
+\begin{alltt}
+nmake -f makefile.msvc
+\end{alltt}
+
+This will build the library and archive the object files in ``tommath.lib''. This has been tested with MSVC
+version 6.00 with service pack 5.
+
+\subsection{Shared Libraries}
+To build as a shared library for GCC issue the following
+\begin{alltt}
+make -f makefile.shared
+\end{alltt}
+This requires the ``libtool'' package (common on most Linux/BSD systems). It will build LibTomMath as both shared
+and static then install (by default) into /usr/lib as well as install the header files in /usr/include. The shared
+library (resource) will be called ``libtommath.la'' while the static library called ``libtommath.a''. Generally
+you use libtool to link your application against the shared object.
+
+There is limited support for making a ``DLL'' in windows via the ``makefile.cygwin\_dll'' makefile. It requires
+Cygwin to work with since it requires the auto-export/import functionality. The resulting DLL and import library
+``libtommath.dll.a'' can be used to link LibTomMath dynamically to any Windows program using Cygwin.
+
+\subsection{Testing}
+To build the library and the test harness type
+
+\begin{alltt}
+make test
+\end{alltt}
+
+This will build the library, ``test'' and ``mtest/mtest''. The ``test'' program will accept test vectors and verify the
+results. ``mtest/mtest'' will generate test vectors using the MPI library by Michael Fromberger\footnote{A copy of MPI
+is included in the package}. Simply pipe mtest into test using
+
+\begin{alltt}
+mtest/mtest | test
+\end{alltt}
+
+If you do not have a ``/dev/urandom'' style RNG source you will have to write your own PRNG and simply pipe that into
+mtest. For example, if your PRNG program is called ``myprng'' simply invoke
+
+\begin{alltt}
+myprng | mtest/mtest | test
+\end{alltt}
+
+This will output a row of numbers that are increasing. Each column is a different test (such as addition, multiplication, etc)
+that is being performed. The numbers represent how many times the test was invoked. If an error is detected the program
+will exit with a dump of the relevent numbers it was working with.
+
+\section{Build Configuration}
+LibTomMath can configured at build time in three phases we shall call ``depends'', ``tweaks'' and ``trims''.
+Each phase changes how the library is built and they are applied one after another respectively.
+
+To make the system more powerful you can tweak the build process. Classes are defined in the file
+``tommath\_superclass.h''. By default, the symbol ``LTM\_ALL'' shall be defined which simply
+instructs the system to build all of the functions. This is how LibTomMath used to be packaged. This will give you
+access to every function LibTomMath offers.
+
+However, there are cases where such a build is not optional. For instance, you want to perform RSA operations. You
+don't need the vast majority of the library to perform these operations. Aside from LTM\_ALL there is
+another pre--defined class ``SC\_RSA\_1'' which works in conjunction with the RSA from LibTomCrypt. Additional
+classes can be defined base on the need of the user.
+
+\subsection{Build Depends}
+In the file tommath\_class.h you will see a large list of C ``defines'' followed by a series of ``ifdefs''
+which further define symbols. All of the symbols (technically they're macros $\ldots$) represent a given C source
+file. For instance, BN\_MP\_ADD\_C represents the file ``bn\_mp\_add.c''. When a define has been enabled the
+function in the respective file will be compiled and linked into the library. Accordingly when the define
+is absent the file will not be compiled and not contribute any size to the library.
+
+You will also note that the header tommath\_class.h is actually recursively included (it includes itself twice).
+This is to help resolve as many dependencies as possible. In the last pass the symbol LTM\_LAST will be defined.
+This is useful for ``trims''.
+
+\subsection{Build Tweaks}
+A tweak is an algorithm ``alternative''. For example, to provide tradeoffs (usually between size and space).
+They can be enabled at any pass of the configuration phase.
+
+\begin{small}
+\begin{center}
+\begin{tabular}{|l|l|}
+\hline \textbf{Define} & \textbf{Purpose} \\
+\hline BN\_MP\_DIV\_SMALL & Enables a slower, smaller and equally \\
+ & functional mp\_div() function \\
+\hline
+\end{tabular}
+\end{center}
+\end{small}
+
+\subsection{Build Trims}
+A trim is a manner of removing functionality from a function that is not required. For instance, to perform
+RSA cryptography you only require exponentiation with odd moduli so even moduli support can be safely removed.
+Build trims are meant to be defined on the last pass of the configuration which means they are to be defined
+only if LTM\_LAST has been defined.
+

+\section{Purpose of LibTomMath}
+Unlike GNU MP (GMP) Library, LIP, OpenSSL or various other commercial kits (Miracl), LibTomMath was not written with
+bleeding edge performance in mind. First and foremost LibTomMath was written to be entirely open. Not only is the
+source code public domain (unlike various other GPL/etc licensed code), not only is the code freely downloadable but the
+source code is also accessible for computer science students attempting to learn ``BigNum'' or multiple precision
+arithmetic techniques.
+
+LibTomMath was written to be an instructive collection of source code. This is why there are many comments, only one
+function per source file and often I use a ``middle-road'' approach where I don't cut corners for an extra 2\% speed
+increase.
+
+Source code alone cannot really teach how the algorithms work which is why I also wrote a textbook that accompanies
+the library (beat that!).
+
+So you may be thinking ``should I use LibTomMath?'' and the answer is a definite maybe. Let me tabulate what I think
+are the pros and cons of LibTomMath by comparing it to the math routines from GnuPG\footnote{GnuPG v1.2.3 versus LibTomMath v0.28}.
+
+\newpage\begin{figure}[here]
+\begin{small}
+\begin{center}
+\begin{tabular}{|l|c|c|l|}
+\hline \textbf{Criteria} & \textbf{Pro} & \textbf{Con} & \textbf{Notes} \\
+\hline Few lines of code per file & X & & GnuPG $ = 300.9$, LibTomMath $ = 71.97$ \\
+\hline Commented function prototypes & X && GnuPG function names are cryptic. \\
+\hline Speed && X & LibTomMath is slower. \\
+\hline Totally free & X & & GPL has unfavourable restrictions.\\
+\hline Large function base & X & & GnuPG is barebones. \\
+\hline Five modular reduction algorithms & X & & Faster modular exponentiation for a variety of moduli. \\
+\hline Portable & X & & GnuPG requires configuration to build. \\
+\hline
+\end{tabular}
+\end{center}
+\end{small}
+\caption{LibTomMath Valuation}
+\end{figure}
+
+It may seem odd to compare LibTomMath to GnuPG since the math in GnuPG is only a small portion of the entire application.
+However, LibTomMath was written with cryptography in mind. It provides essentially all of the functions a cryptosystem
+would require when working with large integers.
+
+So it may feel tempting to just rip the math code out of GnuPG (or GnuMP where it was taken from originally) in your
+own application but I think there are reasons not to. While LibTomMath is slower than libraries such as GnuMP it is
+not normally significantly slower. On x86 machines the difference is normally a factor of two when performing modular
+exponentiations. It depends largely on the processor, compiler and the moduli being used.
+
+Essentially the only time you wouldn't use LibTomMath is when blazing speed is the primary concern. However,
+on the other side of the coin LibTomMath offers you a totally free (public domain) well structured math library
+that is very flexible, complete and performs well in resource contrained environments. Fast RSA for example can
+be performed with as little as 8KB of ram for data (again depending on build options).
+
+\chapter{Getting Started with LibTomMath}
+\section{Building Programs}
+In order to use LibTomMath you must include ``tommath.h'' and link against the appropriate library file (typically
+libtommath.a). There is no library initialization required and the entire library is thread safe.
+
+\section{Return Codes}
+There are three possible return codes a function may return.
+
+\index{MP\_OKAY}\index{MP\_YES}\index{MP\_NO}\index{MP\_VAL}\index{MP\_MEM}
+\begin{figure}[here!]
+\begin{center}
+\begin{small}
+\begin{tabular}{|l|l|}
+\hline \textbf{Code} & \textbf{Meaning} \\
+\hline MP\_OKAY & The function succeeded. \\
+\hline MP\_VAL & The function input was invalid. \\
+\hline MP\_MEM & Heap memory exhausted. \\
+\hline &\\
+\hline MP\_YES & Response is yes. \\
+\hline MP\_NO & Response is no. \\
+\hline
+\end{tabular}
+\end{small}
+\end{center}
+\caption{Return Codes}
+\end{figure}
+
+The last two codes listed are not actually ``return'ed'' by a function. They are placed in an integer (the caller must
+provide the address of an integer it can store to) which the caller can access. To convert one of the three return codes
+to a string use the following function.
+
+\index{mp\_error\_to\_string}
+\begin{alltt}
+char *mp_error_to_string(int code);
+\end{alltt}
+
+This will return a pointer to a string which describes the given error code. It will not work for the return codes
+MP\_YES and MP\_NO.
+
+\section{Data Types}
+The basic ``multiple precision integer'' type is known as the ``mp\_int'' within LibTomMath. This data type is used to
+organize all of the data required to manipulate the integer it represents. Within LibTomMath it has been prototyped
+as the following.
+
+\index{mp\_int}
+\begin{alltt}
+typedef struct \{
+ int used, alloc, sign;
+ mp_digit *dp;
+\} mp_int;
+\end{alltt}
+
+Where ``mp\_digit'' is a data type that represents individual digits of the integer. By default, an mp\_digit is the
+ISO C ``unsigned long'' data type and each digit is $28-$bits long. The mp\_digit type can be configured to suit other
+platforms by defining the appropriate macros.
+
+All LTM functions that use the mp\_int type will expect a pointer to mp\_int structure. You must allocate memory to
+hold the structure itself by yourself (whether off stack or heap it doesn't matter). The very first thing that must be
+done to use an mp\_int is that it must be initialized.
+
+\section{Function Organization}
+
+The arithmetic functions of the library are all organized to have the same style prototype. That is source operands
+are passed on the left and the destination is on the right. For instance,
+
+\begin{alltt}
+mp_add(&a, &b, &c); /* c = a + b */
+mp_mul(&a, &a, &c); /* c = a * a */
+mp_div(&a, &b, &c, &d); /* c = [a/b], d = a mod b */
+\end{alltt}
+
+Another feature of the way the functions have been implemented is that source operands can be destination operands as well.
+For instance,
+
+\begin{alltt}
+mp_add(&a, &b, &b); /* b = a + b */
+mp_div(&a, &b, &a, &c); /* a = [a/b], c = a mod b */
+\end{alltt}
+
+This allows operands to be re-used which can make programming simpler.
+
+\section{Initialization}
+\subsection{Single Initialization}
+A single mp\_int can be initialized with the ``mp\_init'' function.
+
+\index{mp\_init}
+\begin{alltt}
+int mp_init (mp_int * a);
+\end{alltt}
+
+This function expects a pointer to an mp\_int structure and will initialize the members of the structure so the mp\_int
+represents the default integer which is zero. If the functions returns MP\_OKAY then the mp\_int is ready to be used
+by the other LibTomMath functions.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int number;
+ int result;
+
+ if ((result = mp_init(&number)) != MP_OKAY) \{
+ printf("Error initializing the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* use the number */
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Single Free}
+When you are finished with an mp\_int it is ideal to return the heap it used back to the system. The following function
+provides this functionality.
+
+\index{mp\_clear}
+\begin{alltt}
+void mp_clear (mp_int * a);
+\end{alltt}
+
+The function expects a pointer to a previously initialized mp\_int structure and frees the heap it uses. It sets the
+pointer\footnote{The ``dp'' member.} within the mp\_int to \textbf{NULL} which is used to prevent double free situations.
+Is is legal to call mp\_clear() twice on the same mp\_int in a row.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int number;
+ int result;
+
+ if ((result = mp_init(&number)) != MP_OKAY) \{
+ printf("Error initializing the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* use the number */
+
+ /* We're done with it. */
+ mp_clear(&number);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Multiple Initializations}
+Certain algorithms require more than one large integer. In these instances it is ideal to initialize all of the mp\_int
+variables in an ``all or nothing'' fashion. That is, they are either all initialized successfully or they are all
+not initialized.
+
+The mp\_init\_multi() function provides this functionality.
+
+\index{mp\_init\_multi} \index{mp\_clear\_multi}
+\begin{alltt}
+int mp_init_multi(mp_int *mp, ...);
+\end{alltt}
+
+It accepts a \textbf{NULL} terminated list of pointers to mp\_int structures. It will attempt to initialize them all
+at once. If the function returns MP\_OKAY then all of the mp\_int variables are ready to use, otherwise none of them
+are available for use. A complementary mp\_clear\_multi() function allows multiple mp\_int variables to be free'd
+from the heap at the same time.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int num1, num2, num3;
+ int result;
+
+ if ((result = mp_init_multi(&num1,
+ &num2,
+ &num3, NULL)) != MP\_OKAY) \{
+ printf("Error initializing the numbers. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* use the numbers */
+
+ /* We're done with them. */
+ mp_clear_multi(&num1, &num2, &num3, NULL);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Other Initializers}
+To initialized and make a copy of an mp\_int the mp\_init\_copy() function has been provided.
+
+\index{mp\_init\_copy}
+\begin{alltt}
+int mp_init_copy (mp_int * a, mp_int * b);
+\end{alltt}
+
+This function will initialize $a$ and make it a copy of $b$ if all goes well.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int num1, num2;
+ int result;
+
+ /* initialize and do work on num1 ... */
+
+ /* We want a copy of num1 in num2 now */
+ if ((result = mp_init_copy(&num2, &num1)) != MP_OKAY) \{
+ printf("Error initializing the copy. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* now num2 is ready and contains a copy of num1 */
+
+ /* We're done with them. */
+ mp_clear_multi(&num1, &num2, NULL);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+Another less common initializer is mp\_init\_size() which allows the user to initialize an mp\_int with a given
+default number of digits. By default, all initializers allocate \textbf{MP\_PREC} digits. This function lets
+you override this behaviour.
+
+\index{mp\_init\_size}
+\begin{alltt}
+int mp_init_size (mp_int * a, int size);
+\end{alltt}
+
+The $size$ parameter must be greater than zero. If the function succeeds the mp\_int $a$ will be initialized
+to have $size$ digits (which are all initially zero).
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int number;
+ int result;
+
+ /* we need a 60-digit number */
+ if ((result = mp_init_size(&number, 60)) != MP_OKAY) \{
+ printf("Error initializing the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* use the number */
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\section{Maintenance Functions}
+
+\subsection{Reducing Memory Usage}
+When an mp\_int is in a state where it won't be changed again\footnote{A Diffie-Hellman modulus for instance.} excess
+digits can be removed to return memory to the heap with the mp\_shrink() function.
+
+\index{mp\_shrink}
+\begin{alltt}
+int mp_shrink (mp_int * a);
+\end{alltt}
+
+This will remove excess digits of the mp\_int $a$. If the operation fails the mp\_int should be intact without the
+excess digits being removed. Note that you can use a shrunk mp\_int in further computations, however, such operations
+will require heap operations which can be slow. It is not ideal to shrink mp\_int variables that you will further
+modify in the system (unless you are seriously low on memory).
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int number;
+ int result;
+
+ if ((result = mp_init(&number)) != MP_OKAY) \{
+ printf("Error initializing the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* use the number [e.g. pre-computation] */
+
+ /* We're done with it for now. */
+ if ((result = mp_shrink(&number)) != MP_OKAY) \{
+ printf("Error shrinking the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* use it .... */
+
+
+ /* we're done with it. */
+ mp_clear(&number);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Adding additional digits}
+
+Within the mp\_int structure are two parameters which control the limitations of the array of digits that represent
+the integer the mp\_int is meant to equal. The \textit{used} parameter dictates how many digits are significant, that is,
+contribute to the value of the mp\_int. The \textit{alloc} parameter dictates how many digits are currently available in
+the array. If you need to perform an operation that requires more digits you will have to mp\_grow() the mp\_int to
+your desired size.
+
+\index{mp\_grow}
+\begin{alltt}
+int mp_grow (mp_int * a, int size);
+\end{alltt}
+
+This will grow the array of digits of $a$ to $size$. If the \textit{alloc} parameter is already bigger than
+$size$ the function will not do anything.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int number;
+ int result;
+
+ if ((result = mp_init(&number)) != MP_OKAY) \{
+ printf("Error initializing the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* use the number */
+
+ /* We need to add 20 digits to the number */
+ if ((result = mp_grow(&number, number.alloc + 20)) != MP_OKAY) \{
+ printf("Error growing the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+
+ /* use the number */
+
+ /* we're done with it. */
+ mp_clear(&number);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\chapter{Basic Operations}
+\section{Small Constants}
+Setting mp\_ints to small constants is a relatively common operation. To accomodate these instances there are two
+small constant assignment functions. The first function is used to set a single digit constant while the second sets
+an ISO C style ``unsigned long'' constant. The reason for both functions is efficiency. Setting a single digit is quick but the
+domain of a digit can change (it's always at least $0 \ldots 127$).
+
+\subsection{Single Digit}
+
+Setting a single digit can be accomplished with the following function.
+
+\index{mp\_set}
+\begin{alltt}
+void mp_set (mp_int * a, mp_digit b);
+\end{alltt}
+
+This will zero the contents of $a$ and make it represent an integer equal to the value of $b$. Note that this
+function has a return type of \textbf{void}. It cannot cause an error so it is safe to assume the function
+succeeded.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int number;
+ int result;
+
+ if ((result = mp_init(&number)) != MP_OKAY) \{
+ printf("Error initializing the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* set the number to 5 */
+ mp_set(&number, 5);
+
+ /* we're done with it. */
+ mp_clear(&number);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Long Constants}
+
+To set a constant that is the size of an ISO C ``unsigned long'' and larger than a single digit the following function
+can be used.
+
+\index{mp\_set\_int}
+\begin{alltt}
+int mp_set_int (mp_int * a, unsigned long b);
+\end{alltt}
+
+This will assign the value of the 32-bit variable $b$ to the mp\_int $a$. Unlike mp\_set() this function will always
+accept a 32-bit input regardless of the size of a single digit. However, since the value may span several digits
+this function can fail if it runs out of heap memory.
+
+To get the ``unsigned long'' copy of an mp\_int the following function can be used.
+
+\index{mp\_get\_int}
+\begin{alltt}
+unsigned long mp_get_int (mp_int * a);
+\end{alltt}
+
+This will return the 32 least significant bits of the mp\_int $a$.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int number;
+ int result;
+
+ if ((result = mp_init(&number)) != MP_OKAY) \{
+ printf("Error initializing the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* set the number to 654321 (note this is bigger than 127) */
+ if ((result = mp_set_int(&number, 654321)) != MP_OKAY) \{
+ printf("Error setting the value of the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ printf("number == \%lu", mp_get_int(&number));
+
+ /* we're done with it. */
+ mp_clear(&number);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+This should output the following if the program succeeds.
+
+\begin{alltt}
+number == 654321
+\end{alltt}
+
+\subsection{Initialize and Setting Constants}
+To both initialize and set small constants the following two functions are available.
+\index{mp\_init\_set} \index{mp\_init\_set\_int}
+\begin{alltt}
+int mp_init_set (mp_int * a, mp_digit b);
+int mp_init_set_int (mp_int * a, unsigned long b);
+\end{alltt}
+
+Both functions work like the previous counterparts except they first mp\_init $a$ before setting the values.
+
+\begin{alltt}
+int main(void)
+\{
+ mp_int number1, number2;
+ int result;
+
+ /* initialize and set a single digit */
+ if ((result = mp_init_set(&number1, 100)) != MP_OKAY) \{
+ printf("Error setting number1: \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* initialize and set a long */
+ if ((result = mp_init_set_int(&number2, 1023)) != MP_OKAY) \{
+ printf("Error setting number2: \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* display */
+ printf("Number1, Number2 == \%lu, \%lu",
+ mp_get_int(&number1), mp_get_int(&number2));
+
+ /* clear */
+ mp_clear_multi(&number1, &number2, NULL);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt}
+
+If this program succeeds it shall output.
+\begin{alltt}
+Number1, Number2 == 100, 1023
+\end{alltt}
+
+\section{Comparisons}
+
+Comparisons in LibTomMath are always performed in a ``left to right'' fashion. There are three possible return codes
+for any comparison.
+
+\index{MP\_GT} \index{MP\_EQ} \index{MP\_LT}
+\begin{figure}[here]
+\begin{center}
+\begin{tabular}{|c|c|}
+\hline \textbf{Result Code} & \textbf{Meaning} \\
+\hline MP\_GT & $a > b$ \\
+\hline MP\_EQ & $a = b$ \\
+\hline MP\_LT & $a < b$ \\
+\hline
+\end{tabular}
+\end{center}
+\caption{Comparison Codes for $a, b$}
+\label{fig:CMP}
+\end{figure}
+
+In figure \ref{fig:CMP} two integers $a$ and $b$ are being compared. In this case $a$ is said to be ``to the left'' of
+$b$.
+
+\subsection{Unsigned comparison}
+
+An unsigned comparison considers only the digits themselves and not the associated \textit{sign} flag of the
+mp\_int structures. This is analogous to an absolute comparison. The function mp\_cmp\_mag() will compare two
+mp\_int variables based on their digits only.
+
+\index{mp\_cmp\_mag}
+\begin{alltt}
+int mp_cmp_mag(mp_int * a, mp_int * b);
+\end{alltt}
+This will compare $a$ to $b$ placing $a$ to the left of $b$. This function cannot fail and will return one of the
+three compare codes listed in figure \ref{fig:CMP}.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int number1, number2;
+ int result;
+
+ if ((result = mp_init_multi(&number1, &number2, NULL)) != MP_OKAY) \{
+ printf("Error initializing the numbers. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* set the number1 to 5 */
+ mp_set(&number1, 5);
+
+ /* set the number2 to -6 */
+ mp_set(&number2, 6);
+ if ((result = mp_neg(&number2, &number2)) != MP_OKAY) \{
+ printf("Error negating number2. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ switch(mp_cmp_mag(&number1, &number2)) \{
+ case MP_GT: printf("|number1| > |number2|"); break;
+ case MP_EQ: printf("|number1| = |number2|"); break;
+ case MP_LT: printf("|number1| < |number2|"); break;
+ \}
+
+ /* we're done with it. */
+ mp_clear_multi(&number1, &number2, NULL);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program\footnote{This function uses the mp\_neg() function which is discussed in section \ref{sec:NEG}.} completes
+successfully it should print the following.
+
+\begin{alltt}
+|number1| < |number2|
+\end{alltt}
+
+This is because $\vert -6 \vert = 6$ and obviously $5 < 6$.
+
+\subsection{Signed comparison}
+
+To compare two mp\_int variables based on their signed value the mp\_cmp() function is provided.
+
+\index{mp\_cmp}
+\begin{alltt}
+int mp_cmp(mp_int * a, mp_int * b);
+\end{alltt}
+
+This will compare $a$ to the left of $b$. It will first compare the signs of the two mp\_int variables. If they
+differ it will return immediately based on their signs. If the signs are equal then it will compare the digits
+individually. This function will return one of the compare conditions codes listed in figure \ref{fig:CMP}.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int number1, number2;
+ int result;
+
+ if ((result = mp_init_multi(&number1, &number2, NULL)) != MP_OKAY) \{
+ printf("Error initializing the numbers. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* set the number1 to 5 */
+ mp_set(&number1, 5);
+
+ /* set the number2 to -6 */
+ mp_set(&number2, 6);
+ if ((result = mp_neg(&number2, &number2)) != MP_OKAY) \{
+ printf("Error negating number2. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ switch(mp_cmp(&number1, &number2)) \{
+ case MP_GT: printf("number1 > number2"); break;
+ case MP_EQ: printf("number1 = number2"); break;
+ case MP_LT: printf("number1 < number2"); break;
+ \}
+
+ /* we're done with it. */
+ mp_clear_multi(&number1, &number2, NULL);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program\footnote{This function uses the mp\_neg() function which is discussed in section \ref{sec:NEG}.} completes
+successfully it should print the following.
+
+\begin{alltt}
+number1 > number2
+\end{alltt}
+
+\subsection{Single Digit}
+
+To compare a single digit against an mp\_int the following function has been provided.
+
+\index{mp\_cmp\_d}
+\begin{alltt}
+int mp_cmp_d(mp_int * a, mp_digit b);
+\end{alltt}
+
+This will compare $a$ to the left of $b$ using a signed comparison. Note that it will always treat $b$ as
+positive. This function is rather handy when you have to compare against small values such as $1$ (which often
+comes up in cryptography). The function cannot fail and will return one of the tree compare condition codes
+listed in figure \ref{fig:CMP}.
+
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int number;
+ int result;
+
+ if ((result = mp_init(&number)) != MP_OKAY) \{
+ printf("Error initializing the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* set the number to 5 */
+ mp_set(&number, 5);
+
+ switch(mp_cmp_d(&number, 7)) \{
+ case MP_GT: printf("number > 7"); break;
+ case MP_EQ: printf("number = 7"); break;
+ case MP_LT: printf("number < 7"); break;
+ \}
+
+ /* we're done with it. */
+ mp_clear(&number);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program functions properly it will print out the following.
+
+\begin{alltt}
+number < 7
+\end{alltt}
+
+\section{Logical Operations}
+
+Logical operations are operations that can be performed either with simple shifts or boolean operators such as
+AND, XOR and OR directly. These operations are very quick.
+
+\subsection{Multiplication by two}
+
+Multiplications and divisions by any power of two can be performed with quick logical shifts either left or
+right depending on the operation.
+
+When multiplying or dividing by two a special case routine can be used which are as follows.
+\index{mp\_mul\_2} \index{mp\_div\_2}
+\begin{alltt}
+int mp_mul_2(mp_int * a, mp_int * b);
+int mp_div_2(mp_int * a, mp_int * b);
+\end{alltt}
+
+The former will assign twice $a$ to $b$ while the latter will assign half $a$ to $b$. These functions are fast
+since the shift counts and maskes are hardcoded into the routines.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+ mp_int number;
+ int result;
+
+ if ((result = mp_init(&number)) != MP_OKAY) \{
+ printf("Error initializing the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* set the number to 5 */
+ mp_set(&number, 5);
+
+ /* multiply by two */
+ if ((result = mp\_mul\_2(&number, &number)) != MP_OKAY) \{
+ printf("Error multiplying the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+ switch(mp_cmp_d(&number, 7)) \{
+ case MP_GT: printf("2*number > 7"); break;
+ case MP_EQ: printf("2*number = 7"); break;
+ case MP_LT: printf("2*number < 7"); break;
+ \}
+
+ /* now divide by two */
+ if ((result = mp\_div\_2(&number, &number)) != MP_OKAY) \{
+ printf("Error dividing the number. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+ switch(mp_cmp_d(&number, 7)) \{
+ case MP_GT: printf("2*number/2 > 7"); break;
+ case MP_EQ: printf("2*number/2 = 7"); break;
+ case MP_LT: printf("2*number/2 < 7"); break;
+ \}
+
+ /* we're done with it. */
+ mp_clear(&number);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program is successful it will print out the following text.
+
+\begin{alltt}
+2*number > 7
+2*number/2 < 7
+\end{alltt}
+
+Since $10 > 7$ and $5 < 7$. To multiply by a power of two the following function can be used.
+
+\index{mp\_mul\_2d}
+\begin{alltt}
+int mp_mul_2d(mp_int * a, int b, mp_int * c);
+\end{alltt}
+
+This will multiply $a$ by $2^b$ and store the result in ``c''. If the value of $b$ is less than or equal to
+zero the function will copy $a$ to ``c'' without performing any further actions.
+
+To divide by a power of two use the following.
+
+\index{mp\_div\_2d}
+\begin{alltt}
+int mp_div_2d (mp_int * a, int b, mp_int * c, mp_int * d);
+\end{alltt}
+Which will divide $a$ by $2^b$, store the quotient in ``c'' and the remainder in ``d'. If $b \le 0$ then the
+function simply copies $a$ over to ``c'' and zeroes $d$. The variable $d$ may be passed as a \textbf{NULL}
+value to signal that the remainder is not desired.
+
+\subsection{Polynomial Basis Operations}
+
+Strictly speaking the organization of the integers within the mp\_int structures is what is known as a
+``polynomial basis''. This simply means a field element is stored by divisions of a radix. For example, if
+$f(x) = \sum_{i=0}^{k} y_ix^k$ for any vector $\vec y$ then the array of digits in $\vec y$ are said to be
+the polynomial basis representation of $z$ if $f(\beta) = z$ for a given radix $\beta$.
+
+To multiply by the polynomial $g(x) = x$ all you have todo is shift the digits of the basis left one place. The
+following function provides this operation.
+
+\index{mp\_lshd}
+\begin{alltt}
+int mp_lshd (mp_int * a, int b);
+\end{alltt}
+
+This will multiply $a$ in place by $x^b$ which is equivalent to shifting the digits left $b$ places and inserting zeroes
+in the least significant digits. Similarly to divide by a power of $x$ the following function is provided.
+
+\index{mp\_rshd}
+\begin{alltt}
+void mp_rshd (mp_int * a, int b)
+\end{alltt}
+This will divide $a$ in place by $x^b$ and discard the remainder. This function cannot fail as it performs the operations
+in place and no new digits are required to complete it.
+
+\subsection{AND, OR and XOR Operations}
+
+While AND, OR and XOR operations are not typical ``bignum functions'' they can be useful in several instances. The
+three functions are prototyped as follows.
+
+\index{mp\_or} \index{mp\_and} \index{mp\_xor}
+\begin{alltt}
+int mp_or (mp_int * a, mp_int * b, mp_int * c);
+int mp_and (mp_int * a, mp_int * b, mp_int * c);
+int mp_xor (mp_int * a, mp_int * b, mp_int * c);
+\end{alltt}
+
+Which compute $c = a \odot b$ where $\odot$ is one of OR, AND or XOR.
+
+\section{Addition and Subtraction}
+
+To compute an addition or subtraction the following two functions can be used.
+
+\index{mp\_add} \index{mp\_sub}
+\begin{alltt}
+int mp_add (mp_int * a, mp_int * b, mp_int * c);
+int mp_sub (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+
+Which perform $c = a \odot b$ where $\odot$ is one of signed addition or subtraction. The operations are fully sign
+aware.
+
+\section{Sign Manipulation}
+\subsection{Negation}
+\label{sec:NEG}
+Simple integer negation can be performed with the following.
+
+\index{mp\_neg}
+\begin{alltt}
+int mp_neg (mp_int * a, mp_int * b);
+\end{alltt}
+
+Which assigns $-a$ to $b$.
+
+\subsection{Absolute}
+Simple integer absolutes can be performed with the following.
+
+\index{mp\_neg}
+\begin{alltt}
+int mp_abs (mp_int * a, mp_int * b);
+\end{alltt}
+
+Which assigns $\vert a \vert$ to $b$.
+
+\section{Integer Division and Remainder}
+To perform a complete and general integer division with remainder use the following function.
+
+\index{mp\_div}
+\begin{alltt}
+int mp_div (mp_int * a, mp_int * b, mp_int * c, mp_int * d);
+\end{alltt}
+
+This divides $a$ by $b$ and stores the quotient in $c$ and $d$. The signed quotient is computed such that
+$bc + d = a$. Note that either of $c$ or $d$ can be set to \textbf{NULL} if their value is not required. If
+$b$ is zero the function returns \textbf{MP\_VAL}.
+
+
+\chapter{Multiplication and Squaring}
+\section{Multiplication}
+A full signed integer multiplication can be performed with the following.
+\index{mp\_mul}
+\begin{alltt}
+int mp_mul (mp_int * a, mp_int * b, mp_int * c);
+\end{alltt}
+Which assigns the full signed product $ab$ to $c$. This function actually breaks into one of four cases which are
+specific multiplication routines optimized for given parameters. First there are the Toom-Cook multiplications which
+should only be used with very large inputs. This is followed by the Karatsuba multiplications which are for moderate
+sized inputs. Then followed by the Comba and baseline multipliers.
+
+Fortunately for the developer you don't really need to know this unless you really want to fine tune the system. mp\_mul()
+will determine on its own\footnote{Some tweaking may be required.} what routine to use automatically when it is called.
+
+\begin{alltt}
+int main(void)
+\{
+ mp_int number1, number2;
+ int result;
+
+ /* Initialize the numbers */
+ if ((result = mp_init_multi(&number1,
+ &number2, NULL)) != MP_OKAY) \{
+ printf("Error initializing the numbers. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* set the terms */
+ if ((result = mp_set_int(&number, 257)) != MP_OKAY) \{
+ printf("Error setting number1. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ if ((result = mp_set_int(&number2, 1023)) != MP_OKAY) \{
+ printf("Error setting number2. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* multiply them */
+ if ((result = mp_mul(&number1, &number2,
+ &number1)) != MP_OKAY) \{
+ printf("Error multiplying terms. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* display */
+ printf("number1 * number2 == \%lu", mp_get_int(&number1));
+
+ /* free terms and return */
+ mp_clear_multi(&number1, &number2, NULL);
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt}
+
+If this program succeeds it shall output the following.
+
+\begin{alltt}
+number1 * number2 == 262911
+\end{alltt}
+
+\section{Squaring}
+Since squaring can be performed faster than multiplication it is performed it's own function instead of just using
+mp\_mul().
+
+\index{mp\_sqr}
+\begin{alltt}
+int mp_sqr (mp_int * a, mp_int * b);
+\end{alltt}
+
+Will square $a$ and store it in $b$. Like the case of multiplication there are four different squaring
+algorithms all which can be called from mp\_sqr(). It is ideal to use mp\_sqr over mp\_mul when squaring terms because
+of the speed difference.
+
+\section{Tuning Polynomial Basis Routines}
+
+Both of the Toom-Cook and Karatsuba multiplication algorithms are faster than the traditional $O(n^2)$ approach that
+the Comba and baseline algorithms use. At $O(n^{1.464973})$ and $O(n^{1.584962})$ running times respectively they require
+considerably less work. For example, a 10000-digit multiplication would take roughly 724,000 single precision
+multiplications with Toom-Cook or 100,000,000 single precision multiplications with the standard Comba (a factor
+of 138).
+
+So why not always use Karatsuba or Toom-Cook? The simple answer is that they have so much overhead that they're not
+actually faster than Comba until you hit distinct ``cutoff'' points. For Karatsuba with the default configuration,
+GCC 3.3.1 and an Athlon XP processor the cutoff point is roughly 110 digits (about 70 for the Intel P4). That is, at
+110 digits Karatsuba and Comba multiplications just about break even and for 110+ digits Karatsuba is faster.
+
+Toom-Cook has incredible overhead and is probably only useful for very large inputs. So far no known cutoff points
+exist and for the most part I just set the cutoff points very high to make sure they're not called.
+
+A demo program in the ``etc/'' directory of the project called ``tune.c'' can be used to find the cutoff points. This
+can be built with GCC as follows
+
+\begin{alltt}
+make XXX
+\end{alltt}
+Where ``XXX'' is one of the following entries from the table \ref{fig:tuning}.
+
+\begin{figure}[here]
+\begin{center}
+\begin{small}
+\begin{tabular}{|l|l|}
+\hline \textbf{Value of XXX} & \textbf{Meaning} \\
+\hline tune & Builds portable tuning application \\
+\hline tune86 & Builds x86 (pentium and up) program for COFF \\
+\hline tune86c & Builds x86 program for Cygwin \\
+\hline tune86l & Builds x86 program for Linux (ELF format) \\
+\hline
+\end{tabular}
+\end{small}
+\end{center}
+\caption{Build Names for Tuning Programs}
+\label{fig:tuning}
+\end{figure}
+
+When the program is running it will output a series of measurements for different cutoff points. It will first find
+good Karatsuba squaring and multiplication points. Then it proceeds to find Toom-Cook points. Note that the Toom-Cook
+tuning takes a very long time as the cutoff points are likely to be very high.
+
+\chapter{Modular Reduction}
+
+Modular reduction is process of taking the remainder of one quantity divided by another. Expressed
+as (\ref{eqn:mod}) the modular reduction is equivalent to the remainder of $b$ divided by $c$.
+
+\begin{equation}
+a \equiv b \mbox{ (mod }c\mbox{)}
+\label{eqn:mod}
+\end{equation}
+
+Of particular interest to cryptography are reductions where $b$ is limited to the range $0 \le b < c^2$ since particularly
+fast reduction algorithms can be written for the limited range.
+
+Note that one of the four optimized reduction algorithms are automatically chosen in the modular exponentiation
+algorithm mp\_exptmod when an appropriate modulus is detected.
+
+\section{Straight Division}
+In order to effect an arbitrary modular reduction the following algorithm is provided.
+
+\index{mp\_mod}
+\begin{alltt}
+int mp_mod(mp_int *a, mp_int *b, mp_int *c);
+\end{alltt}
+
+This reduces $a$ modulo $b$ and stores the result in $c$. The sign of $c$ shall agree with the sign
+of $b$. This algorithm accepts an input $a$ of any range and is not limited by $0 \le a < b^2$.
+
+\section{Barrett Reduction}
+
+Barrett reduction is a generic optimized reduction algorithm that requires pre--computation to achieve
+a decent speedup over straight division. First a $\mu$ value must be precomputed with the following function.
+
+\index{mp\_reduce\_setup}
+\begin{alltt}
+int mp_reduce_setup(mp_int *a, mp_int *b);
+\end{alltt}
+
+Given a modulus in $b$ this produces the required $\mu$ value in $a$. For any given modulus this only has to
+be computed once. Modular reduction can now be performed with the following.
+
+\index{mp\_reduce}
+\begin{alltt}
+int mp_reduce(mp_int *a, mp_int *b, mp_int *c);
+\end{alltt}
+
+This will reduce $a$ in place modulo $b$ with the precomputed $\mu$ value in $c$. $a$ must be in the range
+$0 \le a < b^2$.
+
+\begin{alltt}
+int main(void)
+\{
+ mp_int a, b, c, mu;
+ int result;
+
+ /* initialize a,b to desired values, mp_init mu,
+ * c and set c to 1...we want to compute a^3 mod b
+ */
+
+ /* get mu value */
+ if ((result = mp_reduce_setup(&mu, b)) != MP_OKAY) \{
+ printf("Error getting mu. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* square a to get c = a^2 */
+ if ((result = mp_sqr(&a, &c)) != MP_OKAY) \{
+ printf("Error squaring. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* now reduce `c' modulo b */
+ if ((result = mp_reduce(&c, &b, &mu)) != MP_OKAY) \{
+ printf("Error reducing. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* multiply a to get c = a^3 */
+ if ((result = mp_mul(&a, &c, &c)) != MP_OKAY) \{
+ printf("Error reducing. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* now reduce `c' modulo b */
+ if ((result = mp_reduce(&c, &b, &mu)) != MP_OKAY) \{
+ printf("Error reducing. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* c now equals a^3 mod b */
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt}
+
+This program will calculate $a^3 \mbox{ mod }b$ if all the functions succeed.
+
+\section{Montgomery Reduction}
+
+Montgomery is a specialized reduction algorithm for any odd moduli. Like Barrett reduction a pre--computation
+step is required. This is accomplished with the following.
+
+\index{mp\_montgomery\_setup}
+\begin{alltt}
+int mp_montgomery_setup(mp_int *a, mp_digit *mp);
+\end{alltt}
+
+For the given odd moduli $a$ the precomputation value is placed in $mp$. The reduction is computed with the
+following.
+
+\index{mp\_montgomery\_reduce}
+\begin{alltt}
+int mp_montgomery_reduce(mp_int *a, mp_int *m, mp_digit mp);
+\end{alltt}
+This reduces $a$ in place modulo $m$ with the pre--computed value $mp$. $a$ must be in the range
+$0 \le a < b^2$.
+
+Montgomery reduction is faster than Barrett reduction for moduli smaller than the ``comba'' limit. With the default
+setup for instance, the limit is $127$ digits ($3556$--bits). Note that this function is not limited to
+$127$ digits just that it falls back to a baseline algorithm after that point.
+
+An important observation is that this reduction does not return $a \mbox{ mod }m$ but $aR^{-1} \mbox{ mod }m$
+where $R = \beta^n$, $n$ is the n number of digits in $m$ and $\beta$ is radix used (default is $2^{28}$).
+
+To quickly calculate $R$ the following function was provided.
+
+\index{mp\_montgomery\_calc\_normalization}
+\begin{alltt}
+int mp_montgomery_calc_normalization(mp_int *a, mp_int *b);
+\end{alltt}
+Which calculates $a = R$ for the odd moduli $b$ without using multiplication or division.
+
+The normal modus operandi for Montgomery reductions is to normalize the integers before entering the system. For
+example, to calculate $a^3 \mbox { mod }b$ using Montgomery reduction the value of $a$ can be normalized by
+multiplying it by $R$. Consider the following code snippet.
+
+\begin{alltt}
+int main(void)
+\{
+ mp_int a, b, c, R;
+ mp_digit mp;
+ int result;
+
+ /* initialize a,b to desired values,
+ * mp_init R, c and set c to 1....
+ */
+
+ /* get normalization */
+ if ((result = mp_montgomery_calc_normalization(&R, b)) != MP_OKAY) \{
+ printf("Error getting norm. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* get mp value */
+ if ((result = mp_montgomery_setup(&c, &mp)) != MP_OKAY) \{
+ printf("Error setting up montgomery. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* normalize `a' so now a is equal to aR */
+ if ((result = mp_mulmod(&a, &R, &b, &a)) != MP_OKAY) \{
+ printf("Error computing aR. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* square a to get c = a^2R^2 */
+ if ((result = mp_sqr(&a, &c)) != MP_OKAY) \{
+ printf("Error squaring. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* now reduce `c' back down to c = a^2R^2 * R^-1 == a^2R */
+ if ((result = mp_montgomery_reduce(&c, &b, mp)) != MP_OKAY) \{
+ printf("Error reducing. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* multiply a to get c = a^3R^2 */
+ if ((result = mp_mul(&a, &c, &c)) != MP_OKAY) \{
+ printf("Error reducing. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* now reduce `c' back down to c = a^3R^2 * R^-1 == a^3R */
+ if ((result = mp_montgomery_reduce(&c, &b, mp)) != MP_OKAY) \{
+ printf("Error reducing. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* now reduce (again) `c' back down to c = a^3R * R^-1 == a^3 */
+ if ((result = mp_montgomery_reduce(&c, &b, mp)) != MP_OKAY) \{
+ printf("Error reducing. \%s",
+ mp_error_to_string(result));
+ return EXIT_FAILURE;
+ \}
+
+ /* c now equals a^3 mod b */
+
+ return EXIT_SUCCESS;
+\}
+\end{alltt}
+
+This particular example does not look too efficient but it demonstrates the point of the algorithm. By
+normalizing the inputs the reduced results are always of the form $aR$ for some variable $a$. This allows
+a single final reduction to correct for the normalization and the fast reduction used within the algorithm.
+
+For more details consider examining the file \textit{bn\_mp\_exptmod\_fast.c}.
+
+\section{Restricted Dimminished Radix}
+
+``Dimminished Radix'' reduction refers to reduction with respect to moduli that are ameniable to simple
+digit shifting and small multiplications. In this case the ``restricted'' variant refers to moduli of the
+form $\beta^k - p$ for some $k \ge 0$ and $0 < p < \beta$ where $\beta$ is the radix (default to $2^{28}$).
+
+As in the case of Montgomery reduction there is a pre--computation phase required for a given modulus.
+
+\index{mp\_dr\_setup}
+\begin{alltt}
+void mp_dr_setup(mp_int *a, mp_digit *d);
+\end{alltt}
+
+This computes the value required for the modulus $a$ and stores it in $d$. This function cannot fail
+and does not return any error codes. After the pre--computation a reduction can be performed with the
+following.
+
+\index{mp\_dr\_reduce}
+\begin{alltt}
+int mp_dr_reduce(mp_int *a, mp_int *b, mp_digit mp);
+\end{alltt}
+
+This reduces $a$ in place modulo $b$ with the pre--computed value $mp$. $b$ must be of a restricted
+dimminished radix form and $a$ must be in the range $0 \le a < b^2$. Dimminished radix reductions are
+much faster than both Barrett and Montgomery reductions as they have a much lower asymtotic running time.
+
+Since the moduli are restricted this algorithm is not particularly useful for something like Rabin, RSA or
+BBS cryptographic purposes. This reduction algorithm is useful for Diffie-Hellman and ECC where fixed
+primes are acceptable.
+
+Note that unlike Montgomery reduction there is no normalization process. The result of this function is
+equal to the correct residue.
+
+\section{Unrestricted Dimminshed Radix}
+
+Unrestricted reductions work much like the restricted counterparts except in this case the moduli is of the
+form $2^k - p$ for $0 < p < \beta$. In this sense the unrestricted reductions are more flexible as they
+can be applied to a wider range of numbers.
+
+\index{mp\_reduce\_2k\_setup}
+\begin{alltt}
+int mp_reduce_2k_setup(mp_int *a, mp_digit *d);
+\end{alltt}
+
+This will compute the required $d$ value for the given moduli $a$.
+
+\index{mp\_reduce\_2k}
+\begin{alltt}
+int mp_reduce_2k(mp_int *a, mp_int *n, mp_digit d);
+\end{alltt}
+
+This will reduce $a$ in place modulo $n$ with the pre--computed value $d$. From my experience this routine is
+slower than mp\_dr\_reduce but faster for most moduli sizes than the Montgomery reduction.
+
+\chapter{Exponentiation}
+\section{Single Digit Exponentiation}
+\index{mp\_expt\_d}
+\begin{alltt}
+int mp_expt_d (mp_int * a, mp_digit b, mp_int * c)
+\end{alltt}
+This computes $c = a^b$ using a simple binary left-to-right algorithm. It is faster than repeated multiplications by
+$a$ for all values of $b$ greater than three.
+
+\section{Modular Exponentiation}
+\index{mp\_exptmod}
+\begin{alltt}
+int mp_exptmod (mp_int * G, mp_int * X, mp_int * P, mp_int * Y)
+\end{alltt}
+This computes $Y \equiv G^X \mbox{ (mod }P\mbox{)}$ using a variable width sliding window algorithm. This function
+will automatically detect the fastest modular reduction technique to use during the operation. For negative values of
+$X$ the operation is performed as $Y \equiv (G^{-1} \mbox{ mod }P)^{\vert X \vert} \mbox{ (mod }P\mbox{)}$ provided that
+$gcd(G, P) = 1$.
+
+This function is actually a shell around the two internal exponentiation functions. This routine will automatically
+detect when Barrett, Montgomery, Restricted and Unrestricted Dimminished Radix based exponentiation can be used. Generally
+moduli of the a ``restricted dimminished radix'' form lead to the fastest modular exponentiations. Followed by Montgomery
+and the other two algorithms.
+
+\section{Root Finding}
+\index{mp\_n\_root}
+\begin{alltt}
+int mp_n_root (mp_int * a, mp_digit b, mp_int * c)
+\end{alltt}
+This computes $c = a^{1/b}$ such that $c^b \le a$ and $(c+1)^b > a$. The implementation of this function is not
+ideal for values of $b$ greater than three. It will work but become very slow. So unless you are working with very small
+numbers (less than 1000 bits) I'd avoid $b > 3$ situations. Will return a positive root only for even roots and return
+a root with the sign of the input for odd roots. For example, performing $4^{1/2}$ will return $2$ whereas $(-8)^{1/3}$
+will return $-2$.
+
+This algorithm uses the ``Newton Approximation'' method and will converge on the correct root fairly quickly. Since
+the algorithm requires raising $a$ to the power of $b$ it is not ideal to attempt to find roots for large
+values of $b$. If particularly large roots are required then a factor method could be used instead. For example,
+$a^{1/16}$ is equivalent to $\left (a^{1/4} \right)^{1/4}$ or simply
+$\left ( \left ( \left ( a^{1/2} \right )^{1/2} \right )^{1/2} \right )^{1/2}$
+
+\chapter{Prime Numbers}
+\section{Trial Division}
+\index{mp\_prime\_is\_divisible}
+\begin{alltt}
+int mp_prime_is_divisible (mp_int * a, int *result)
+\end{alltt}
+This will attempt to evenly divide $a$ by a list of primes\footnote{Default is the first 256 primes.} and store the
+outcome in ``result''. That is if $result = 0$ then $a$ is not divisible by the primes, otherwise it is. Note that
+if the function does not return \textbf{MP\_OKAY} the value in ``result'' should be considered undefined\footnote{Currently
+the default is to set it to zero first.}.
+
+\section{Fermat Test}
+\index{mp\_prime\_fermat}
+\begin{alltt}
+int mp_prime_fermat (mp_int * a, mp_int * b, int *result)
+\end{alltt}
+Performs a Fermat primality test to the base $b$. That is it computes $b^a \mbox{ mod }a$ and tests whether the value is
+equal to $b$ or not. If the values are equal then $a$ is probably prime and $result$ is set to one. Otherwise $result$
+is set to zero.
+
+\section{Miller-Rabin Test}
+\index{mp\_prime\_miller\_rabin}
+\begin{alltt}
+int mp_prime_miller_rabin (mp_int * a, mp_int * b, int *result)
+\end{alltt}
+Performs a Miller-Rabin test to the base $b$ of $a$. This test is much stronger than the Fermat test and is very hard to
+fool (besides with Carmichael numbers). If $a$ passes the test (therefore is probably prime) $result$ is set to one.
+Otherwise $result$ is set to zero.
+
+Note that is suggested that you use the Miller-Rabin test instead of the Fermat test since all of the failures of
+Miller-Rabin are a subset of the failures of the Fermat test.
+
+\subsection{Required Number of Tests}
+Generally to ensure a number is very likely to be prime you have to perform the Miller-Rabin with at least a half-dozen
+or so unique bases. However, it has been proven that the probability of failure goes down as the size of the input goes up.
+This is why a simple function has been provided to help out.
+
+\index{mp\_prime\_rabin\_miller\_trials}
+\begin{alltt}
+int mp_prime_rabin_miller_trials(int size)
+\end{alltt}
+This returns the number of trials required for a $2^{-96}$ (or lower) probability of failure for a given ``size'' expressed
+in bits. This comes in handy specially since larger numbers are slower to test. For example, a 512-bit number would
+require ten tests whereas a 1024-bit number would only require four tests.
+
+You should always still perform a trial division before a Miller-Rabin test though.
+
+\section{Primality Testing}
+\index{mp\_prime\_is\_prime}
+\begin{alltt}
+int mp_prime_is_prime (mp_int * a, int t, int *result)
+\end{alltt}
+This will perform a trial division followed by $t$ rounds of Miller-Rabin tests on $a$ and store the result in $result$.
+If $a$ passes all of the tests $result$ is set to one, otherwise it is set to zero. Note that $t$ is bounded by
+$1 \le t < PRIME\_SIZE$ where $PRIME\_SIZE$ is the number of primes in the prime number table (by default this is $256$).
+
+\section{Next Prime}
+\index{mp\_prime\_next\_prime}
+\begin{alltt}
+int mp_prime_next_prime(mp_int *a, int t, int bbs_style)
+\end{alltt}
+This finds the next prime after $a$ that passes mp\_prime\_is\_prime() with $t$ tests. Set $bbs\_style$ to one if you
+want only the next prime congruent to $3 \mbox{ mod } 4$, otherwise set it to zero to find any next prime.
+
+\section{Random Primes}
+\index{mp\_prime\_random}
+\begin{alltt}
+int mp_prime_random(mp_int *a, int t, int size, int bbs,
+ ltm_prime_callback cb, void *dat)
+\end{alltt}
+This will find a prime greater than $256^{size}$ which can be ``bbs\_style'' or not depending on $bbs$ and must pass
+$t$ rounds of tests. The ``ltm\_prime\_callback'' is a typedef for
+
+\begin{alltt}
+typedef int ltm_prime_callback(unsigned char *dst, int len, void *dat);
+\end{alltt}
+
+Which is a function that must read $len$ bytes (and return the amount stored) into $dst$. The $dat$ variable is simply
+copied from the original input. It can be used to pass RNG context data to the callback. The function
+mp\_prime\_random() is more suitable for generating primes which must be secret (as in the case of RSA) since there
+is no skew on the least significant bits.
+
+\textit{Note:} As of v0.30 of the LibTomMath library this function has been deprecated. It is still available
+but users are encouraged to use the new mp\_prime\_random\_ex() function instead.
+
+\subsection{Extended Generation}
+\index{mp\_prime\_random\_ex}
+\begin{alltt}
+int mp_prime_random_ex(mp_int *a, int t,
+ int size, int flags,
+ ltm_prime_callback cb, void *dat);
+\end{alltt}
+This will generate a prime in $a$ using $t$ tests of the primality testing algorithms. The variable $size$
+specifies the bit length of the prime desired. The variable $flags$ specifies one of several options available
+(see fig. \ref{fig:primeopts}) which can be OR'ed together. The callback parameters are used as in
+mp\_prime\_random().
+

+\section{ASCII Conversions}
+\subsection{To ASCII}
+\index{mp\_toradix}
+\begin{alltt}
+int mp_toradix (mp_int * a, char *str, int radix);
+\end{alltt}
+This still store $a$ in ``str'' as a base-``radix'' string of ASCII chars. This function appends a NUL character
+to terminate the string. Valid values of ``radix'' line in the range $[2, 64]$. To determine the size (exact) required
+by the conversion before storing any data use the following function.
+
+\index{mp\_radix\_size}
+\begin{alltt}
+int mp_radix_size (mp_int * a, int radix, int *size)
+\end{alltt}
+This stores in ``size'' the number of characters (including space for the NUL terminator) required. Upon error this
+function returns an error code and ``size'' will be zero.
+
+\subsection{From ASCII}
+\index{mp\_read\_radix}
+\begin{alltt}
+int mp_read_radix (mp_int * a, char *str, int radix);
+\end{alltt}
+This will read the base-``radix'' NUL terminated string from ``str'' into $a$. It will stop reading when it reads a
+character it does not recognize (which happens to include th NUL char... imagine that...). A single leading $-$ sign
+can be used to denote a negative number.
+
+\section{Binary Conversions}
+
+Converting an mp\_int to and from binary is another keen idea.
+
+\index{mp\_unsigned\_bin\_size}
+\begin{alltt}
+int mp_unsigned_bin_size(mp_int *a);
+\end{alltt}
+
+This will return the number of bytes (octets) required to store the unsigned copy of the integer $a$.
+
+\index{mp\_to\_unsigned\_bin}
+\begin{alltt}
+int mp_to_unsigned_bin(mp_int *a, unsigned char *b);
+\end{alltt}
+This will store $a$ into the buffer $b$ in big--endian format. Fortunately this is exactly what DER (or is it ASN?)
+requires. It does not store the sign of the integer.
+
+\index{mp\_read\_unsigned\_bin}
+\begin{alltt}
+int mp_read_unsigned_bin(mp_int *a, unsigned char *b, int c);
+\end{alltt}
+This will read in an unsigned big--endian array of bytes (octets) from $b$ of length $c$ into $a$. The resulting
+integer $a$ will always be positive.
+
+For those who acknowledge the existence of negative numbers (heretic!) there are ``signed'' versions of the
+previous functions.
+
+\begin{alltt}
+int mp_signed_bin_size(mp_int *a);
+int mp_read_signed_bin(mp_int *a, unsigned char *b, int c);
+int mp_to_signed_bin(mp_int *a, unsigned char *b);
+\end{alltt}
+They operate essentially the same as the unsigned copies except they prefix the data with zero or non--zero
+byte depending on the sign. If the sign is zpos (e.g. not negative) the prefix is zero, otherwise the prefix
+is non--zero.
+
+\chapter{Algebraic Functions}
+\section{Extended Euclidean Algorithm}
+\index{mp\_exteuclid}
+\begin{alltt}
+int mp_exteuclid(mp_int *a, mp_int *b,
+ mp_int *U1, mp_int *U2, mp_int *U3);
+\end{alltt}
+
+This finds the triple U1/U2/U3 using the Extended Euclidean algorithm such that the following equation holds.
+
+\begin{equation}
+a \cdot U1 + b \cdot U2 = U3
+\end{equation}
+
+Any of the U1/U2/U3 paramters can be set to \textbf{NULL} if they are not desired.
+
+\section{Greatest Common Divisor}
+\index{mp\_gcd}
+\begin{alltt}
+int mp_gcd (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+This will compute the greatest common divisor of $a$ and $b$ and store it in $c$.
+
+\section{Least Common Multiple}
+\index{mp\_lcm}
+\begin{alltt}
+int mp_lcm (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+This will compute the least common multiple of $a$ and $b$ and store it in $c$.
+
+\section{Jacobi Symbol}
+\index{mp\_jacobi}
+\begin{alltt}
+int mp_jacobi (mp_int * a, mp_int * p, int *c)
+\end{alltt}
+This will compute the Jacobi symbol for $a$ with respect to $p$. If $p$ is prime this essentially computes the Legendre
+symbol. The result is stored in $c$ and can take on one of three values $\lbrace -1, 0, 1 \rbrace$. If $p$ is prime
+then the result will be $-1$ when $a$ is not a quadratic residue modulo $p$. The result will be $0$ if $a$ divides $p$
+and the result will be $1$ if $a$ is a quadratic residue modulo $p$.
+
+\section{Modular Inverse}
+\index{mp\_invmod}
+\begin{alltt}
+int mp_invmod (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+Computes the multiplicative inverse of $a$ modulo $b$ and stores the result in $c$ such that $ac \equiv 1 \mbox{ (mod }b\mbox{)}$.
+
+\section{Single Digit Functions}
+
+For those using small numbers (\textit{snicker snicker}) there are several ``helper'' functions
+

+ *
+ * The library is free for all purposes without any express

+
+November 18th, 2005
+v0.37 -- [Don Porter] reported on a TCL list [HEY SEND ME BUGREPORTS ALREADY!!!] that mp_add_d() would compute -0 with some inputs. Fixed.
+ -- [rinick@gmail.com] reported the makefile.bcc was messed up. Fixed.
+ -- [Kevin Kenny] reported some issues with mp_toradix_n(). Now it doesn't require a min of 3 chars of output.
+ -- Made the make command renamable. Wee
+
+August 1st, 2005
+v0.36 -- LTM_PRIME_2MSB_ON was fixed and the "OFF" flag was removed.
+ -- [Peter LaDow] found a typo in the XREALLOC macro
+ -- [Peter LaDow] pointed out that mp_read_(un)signed_bin should have "const" on the input
+ -- Ported LTC patch to fix the prime_random_ex() function to get the bitsize correct [and the maskOR flags]
+ -- Kevin Kenny pointed out a stray //
+ -- David Hulton pointed out a typo in the textbook [mp_montgomery_setup() pseudo-code]
+ -- Neal Hamilton (Elliptic Semiconductor) pointed out that my Karatsuba notation was backwards and that I could use
+ unsigned operations in the routine.
+ -- Paul Schmidt pointed out a linking error in mp_exptmod() when BN_S_MP_EXPTMOD_C is undefined (and another for read_radix)
+ -- Updated makefiles to be way more flexible
+
+March 12th, 2005
+v0.35 -- Stupid XOR function missing line again... oops.
+ -- Fixed bug in invmod not handling negative inputs correctly [Wolfgang Ehrhardt]
+ -- Made exteuclid always give positive u3 output...[ Wolfgang Ehrhardt ]
+ -- [Wolfgang Ehrhardt] Suggested a fix for mp_reduce() which avoided underruns. ;-)

+ Actually is faster than Montgomery on my AMD64 (and probably much faster on a P4)
+ -- Updated the manual a bit
+ -- Ok so I haven't done the textbook work yet... My current freelance gig has landed me in France till the
+ end of Feb/05. Once I get back I'll have tons of free time and I plan to go to town on the book.
+ As of this release the API will freeze. At least until the book catches up with all the changes. I welcome
+ bug reports but new algorithms will have to wait.
+
+December 23rd, 2004
+v0.33 -- Fixed "small" variant for mp_div() which would munge with negative dividends...
+ -- Fixed bug in mp_prime_random_ex() which would set the most significant byte to zero when
+ no special flags were set

+ -- Made the makefiles easier to configure the group/user that ltm will install as
+ -- Fixed "final carry" bug in comba multipliers. (Volkan Ceylan)
+ -- Matt Johnston pointed out a missing semi-colon in mp_exptmod
+
+October 29th, 2004
+v0.32 -- Added "makefile.shared" for shared object support
+ -- Added more to the build options/configs in the manual
+ -- Started the Depends framework, wrote dep.pl to scan deps and
+ produce "callgraph.txt" ;-)
+ -- Wrote SC_RSA_1 which will enable close to the minimum required to perform
+ RSA on 32-bit [or 64-bit] platforms with LibTomCrypt
+ -- Merged in the small/slower mp_div replacement. You can now toggle which
+ you want to use as your mp_div() at build time. Saves roughly 8KB or so.
+ -- Renamed a few files and changed some comments to make depends system work better.
+ (No changes to function names)
+ -- Merged in new Combas that perform 2 reads per inner loop instead of the older
+ 3reads/2writes per inner loop of the old code. Really though if you want speed
+ learn to use TomsFastMath ;-)
+
+August 9th, 2004
+v0.31 -- "profiled" builds now :-) new timings for Intel Northwoods
+ -- Added "pretty" build target
+ -- Update mp_init() to actually assign 0's instead of relying on calloc()
+ -- "Wolfgang Ehrhardt" <Wolfgang.Ehrhardt@munich.netsurf.de> found a bug in mp_mul() where if
+ you multiply a negative by zero you get negative zero as the result. Oops.
+ -- J Harper from PeerSec let me toy with his AMD64 and I got 60-bit digits working properly
+ [this also means that I fixed a bug where if sizeof(int) < sizeof(mp_digit) it would bug]
+
+April 11th, 2004
+v0.30 -- Added "mp_toradix_n" which stores upto "n-1" least significant digits of an mp_int
+ -- Johan Lindh sent a patch so MSVC wouldn't whine about redefining malloc [in weird dll modes]
+ -- Henrik Goldman spotted a missing OPT_CAST in mp_fwrite()
+ -- Tuned tommath.h so that when MP_LOW_MEM is defined MP_PREC shall be reduced.
+ [I also allow MP_PREC to be externally defined now]
+ -- Sped up mp_cnt_lsb() by using a 4x4 table [e.g. 4x speedup]
+ -- Added mp_prime_random_ex() which is a more versatile prime generator accurate to
+ exact bit lengths (unlike the deprecated but still available mp_prime_random() which
+ is only accurate to byte lengths). See the new LTM_PRIME_* flags ;-)
+ -- Alex Polushin contributed an optimized mp_sqrt() as well as mp_get_int() and mp_is_square().
+ I've cleaned them all up to be a little more consistent [along with one bug fix] for this release.
+ -- Added mp_init_set and mp_init_set_int to initialize and set small constants with one function
+ call.
+ -- Removed /etclib directory [um LibTomPoly deprecates this].
+ -- Fixed mp_mod() so the sign of the result agrees with the sign of the modulus.
+ ++ N.B. My semester is almost up so expect updates to the textbook to be posted to the libtomcrypt.org
+ website.
+
+Jan 25th, 2004
+v0.29 ++ Note: "Henrik" from the v0.28 changelog refers to Henrik Goldman ;-)
+ -- Added fix to mp_shrink to prevent a realloc when used == 0 [e.g. realloc zero bytes???]
+ -- Made the mp_prime_rabin_miller_trials() function internal table smaller and also
+ set the minimum number of tests to two (sounds a bit safer).
+ -- Added a mp_exteuclid() which computes the extended euclidean algorithm.
+ -- Fixed a memory leak in s_mp_exptmod() [called when Barrett reduction is to be used] which would arise
+ if a multiplication or subsequent reduction failed [would not free the temp result].
+ -- Made an API change to mp_radix_size(). It now returns an error code and stores the required size
+ through an "int star" passed to it.
+
+Dec 24th, 2003
+v0.28 -- Henrik Goldman suggested I add casts to the montomgery code [stores into mu...] so compilers wouldn't
+ spew [erroneous] diagnostics... fixed.
+ -- Henrik Goldman also spotted two typos. One in mp_radix_size() and another in mp_toradix().
+ -- Added fix to mp_shrink() to avoid a memory leak.
+ -- Added mp_prime_random() which requires a callback to make truly random primes of a given nature
+ (idea from chat with Niels Ferguson at Crypto'03)
+ -- Picked up a second wind. I'm filled with Gooo. Mission Gooo!
+ -- Removed divisions from mp_reduce_is_2k()
+ -- Sped up mp_div_d() [general case] to use only one division per digit instead of two.
+ -- Added the heap macros from LTC to LTM. Now you can easily [by editing four lines of tommath.h]
+ change the name of the heap functions used in LTM [also compatible with LTC via MPI mode]
+ -- Added bn_prime_rabin_miller_trials() which gives the number of Rabin-Miller trials to achieve
+ a failure rate of less than 2^-96
+ -- fixed bug in fast_mp_invmod(). The initial testing logic was wrong. An invalid input is not when
+ "a" and "b" are even it's when "b" is even [the algo is for odd moduli only].
+ -- Started a new manual [finally]. It is incomplete and will be finished as time goes on. I had to stop
+ adding full demos around half way in chapter three so I could at least get a good portion of the
+ manual done. If you really need help using the library you can always email me!
+ -- My Textbook is now included as part of the package [all Public Domain]
+
+Sept 19th, 2003
+v0.27 -- Removed changes.txt~ which was made by accident since "kate" decided it was
+ a good time to re-enable backups... [kde is fun!]
+ -- In mp_grow() "a->dp" is not overwritten by realloc call [re: memory leak]
+ Now if mp_grow() fails the mp_int is still valid and can be cleared via
+ mp_clear() to reclaim the memory.
+ -- Henrik Goldman found a buffer overflow bug in mp_add_d(). Fixed.
+ -- Cleaned up mp_mul_d() to be much easier to read and follow.
+
+Aug 29th, 2003
+v0.26 -- Fixed typo that caused warning with GCC 3.2
+ -- Martin Marcel noticed a bug in mp_neg() that allowed negative zeroes.
+ Also, Martin is the fellow who noted the bugs in mp_gcd() of 0.24/0.25.
+ -- Martin Marcel noticed an optimization [and slight bug] in mp_lcm().
+ -- Added fix to mp_read_unsigned_bin to prevent a buffer overflow.
+ -- Beefed up the comments in the baseline multipliers [and montgomery]
+ -- Added "mont" demo to the makefile.msvc in etc/
+ -- Optimized sign compares in mp_cmp from 4 to 2 cases.
+
+Aug 4th, 2003
+v0.25 -- Fix to mp_gcd again... oops (0,-a) == (-a, 0) == a
+ -- Fix to mp_clear which didn't reset the sign [Greg Rose]
+ -- Added mp_error_to_string() to convert return codes to strings. [Greg Rose]
+ -- Optimized fast_mp_invmod() to do the test for invalid inputs [both even]
+ first so temps don't have to be initialized if it's going to fail.
+ -- Optimized mp_gcd() by removing mp_div_2d calls for when one of the inputs
+ is odd.
+ -- Tons of new comments, some indentation fixups, etc.
+ -- mp_jacobi() returns MP_VAL if the modulus is less than or equal to zero.
+ -- fixed two typos in the header of each file :-)
+ -- LibTomMath is officially Public Domain [see LICENSE]
+
+July 15th, 2003
+v0.24 -- Optimized mp_add_d and mp_sub_d to not allocate temporary variables
+ -- Fixed mp_gcd() so the gcd of 0,0 is 0. Allows the gcd operation to be chained
+ e.g. (0,0,a) == a [instead of 1]
+ -- Should be one of the last release for a while. Working on LibTomMath book now.
+ -- optimized the pprime demo [/etc/pprime.c] to first make a huge table of single
+ digit primes then it reads them randomly instead of randomly choosing/testing single
+ digit primes.
+
+July 12th, 2003
+v0.23 -- Optimized mp_prime_next_prime() to not use mp_mod [via is_divisible()] in each
+ iteration. Instead now a smaller table is kept of the residues which can be updated
+ without division.
+ -- Fixed a bug in next_prime() where an input of zero would be treated as odd and
+ have two added to it [to move to the next odd].
+ -- fixed a bug in prime_fermat() and prime_miller_rabin() which allowed the base
+ to be negative, zero or one. Normally the test is only valid if the base is
+ greater than one.
+ -- changed the next_prime() prototype to accept a new parameter "bbs_style" which
+ will find the next prime congruent to 3 mod 4. The default [bbs_style==0] will
+ make primes which are either congruent to 1 or 3 mod 4.
+ -- fixed mp_read_unsigned_bin() so that it doesn't include both code for
+ the case DIGIT_BIT < 8 and >= 8
+ -- optimized div_d() to easy out on division by 1 [or if a == 0] and use
+ logical shifts if the divisor is a power of two.
+ -- the default DIGIT_BIT type was not int for non-default builds. Fixed.
+
+July 2nd, 2003
+v0.22 -- Fixed up mp_invmod so the result is properly in range now [was always congruent to the inverse...]
+ -- Fixed up s_mp_exptmod and mp_exptmod_fast so the lower half of the pre-computed table isn't allocated
+ which makes the algorithm use half as much ram.
+ -- Fixed the install script not to make the book :-) [which isn't included anyways]
+ -- added mp_cnt_lsb() which counts how many of the lsbs are zero
+ -- optimized mp_gcd() to use the new mp_cnt_lsb() to replace multiple divisions by two by a single division.
+ -- applied similar optimization to mp_prime_miller_rabin().
+ -- Fixed a bug in both mp_invmod() and fast_mp_invmod() which tested for odd
+ via "mp_iseven() == 0" which is not valid [since zero is not even either].
+
+June 19th, 2003
+v0.21 -- Fixed bug in mp_mul_d which would not handle sign correctly [would not always forward it]
+ -- Removed the #line lines from gen.pl [was in violation of ISO C]
+
+June 8th, 2003
+v0.20 -- Removed the book from the package. Added the TDCAL license document.
+ -- This release is officially pure-bred TDCAL again [last officially TDCAL based release was v0.16]
+
+June 6th, 2003
+v0.19 -- Fixed a bug in mp_montgomery_reduce() which was introduced when I tweaked mp_rshd() in the previous release.
+ Essentially the digits were not trimmed before the compare which cause a subtraction to occur all the time.
+ -- Fixed up etc/tune.c a bit to stop testing new cutoffs after 16 failures [to find more optimal points].
+ Brute force ho!
+
+
+May 29th, 2003
+v0.18 -- Fixed a bug in s_mp_sqr which would handle carries properly just not very elegantly.
+ (e.g. correct result, just bad looking code)
+ -- Fixed bug in mp_sqr which still had a 512 constant instead of MP_WARRAY
+ -- Added Toom-Cook multipliers [needs tuning!]
+ -- Added efficient divide by 3 algorithm mp_div_3
+ -- Re-wrote mp_div_d to be faster than calling mp_div
+ -- Added in a donated BCC makefile and a single page LTM poster (ahalhabsi@sbcglobal.net)
+ -- Added mp_reduce_2k which reduces an input modulo n = 2**p - k for any single digit k
+ -- Made the exptmod system be aware of the 2k reduction algorithms.
+ -- Rewrote mp_dr_reduce to be smaller, simpler and easier to understand.
+
+May 17th, 2003
+v0.17 -- Benjamin Goldberg submitted optimized mp_add and mp_sub routines. A new gen.pl as well
+ as several smaller suggestions. Thanks!
+ -- removed call to mp_cmp in inner loop of mp_div and put mp_cmp_mag in its place :-)
+ -- Fixed bug in mp_exptmod that would cause it to fail for odd moduli when DIGIT_BIT != 28
+ -- mp_exptmod now also returns errors if the modulus is negative and will handle negative exponents
+ -- mp_prime_is_prime will now return true if the input is one of the primes in the prime table
+ -- Damian M Gryski (dgryski@uwaterloo.ca) found a index out of bounds error in the
+ mp_fast_s_mp_mul_high_digs function which didn't come up before. (fixed)
+ -- Refactored the DR reduction code so there is only one function per file.
+ -- Fixed bug in the mp_mul() which would erroneously avoid the faster multiplier [comba] when it was
+ allowed. The bug would not cause the incorrect value to be produced just less efficient (fixed)
+ -- Fixed similar bug in the Montgomery reduction code.
+ -- Added tons of (mp_digit) casts so the 7/15/28/31 bit digit code will work flawlessly out of the box.
+ Also added limited support for 64-bit machines with a 60-bit digit. Both thanks to Tom Wu (tom@arcot.com)
+ -- Added new comments here and there, cleaned up some code [style stuff]
+ -- Fixed a lingering typo in mp_exptmod* that would set bitcnt to zero then one. Very silly stuff :-)
+ -- Fixed up mp_exptmod_fast so it would set "redux" to the comba Montgomery reduction if allowed. This
+ saves quite a few calls and if statements.
+ -- Added etc/mont.c a test of the Montgomery reduction [assuming all else works :-| ]
+ -- Fixed up etc/tune.c to use a wider test range [more appropriate] also added a x86 based addition which
+ uses RDTSC for high precision timing.
+ -- Updated demo/demo.c to remove MPI stuff [won't work anyways], made the tests run for 2 seconds each so its
+ not so insanely slow. Also made the output space delimited [and fixed up various errors]
+ -- Added logs directory, logs/graph.dem which will use gnuplot to make a series of PNG files
+ that go with the pre-made index.html. You have to build [via make timing] and run ltmtest first in the
+ root of the package.
+ -- Fixed a bug in mp_sub and mp_add where "-a - -a" or "-a + a" would produce -0 as the result [obviously invalid].
+ -- Fixed a bug in mp_rshd. If the count == a.used it should zero/return [instead of shifting]
+ -- Fixed a "off-by-one" bug in mp_mul2d. The initial size check on alloc would be off by one if the residue
+ shifting caused a carry.
+ -- Fixed a bug where s_mp_mul_digs() would not call the Comba based routine if allowed. This made Barrett reduction
+ slower than it had to be.
+
+Mar 29th, 2003
+v0.16 -- Sped up mp_div by making normalization one shift call
+ -- Sped up mp_mul_2d/mp_div_2d by aliasing pointers :-)
+ -- Cleaned up mp_gcd to use the macros for odd/even detection
+ -- Added comments here and there, mostly there but occasionally here too.
+
+Mar 22nd, 2003
+v0.15 -- Added series of prime testing routines to lib
+ -- Fixed up etc/tune.c
+ -- Added DR reduction algorithm
+ -- Beefed up the manual more.
+ -- Fixed up demo/demo.c so it doesn't have so many warnings and it does the full series of
+ tests
+ -- Added "pre-gen" directory which will hold a "gen.pl"'ed copy of the entire lib [done at
+ zipup time so its always the latest]
+ -- Added conditional casts for C++ users [boo!]
+
+Mar 15th, 2003
+v0.14 -- Tons of manual updates
+ -- cleaned up the directory
+ -- added MSVC makefiles
+ -- source changes [that I don't recall]
+ -- Fixed up the lshd/rshd code to use pointer aliasing
+ -- Fixed up the mul_2d and div_2d to not call rshd/lshd unless needed
+ -- Fixed up etc/tune.c a tad
+ -- fixed up demo/demo.c to output comma-delimited results of timing
+ also fixed up timing demo to use a finer granularity for various functions
+ -- fixed up demo/demo.c testing to pause during testing so my Duron won't catch on fire
+ [stays around 31-35C during testing :-)]
+
+Feb 13th, 2003
+v0.13 -- tons of minor speed-ups in low level add, sub, mul_2 and div_2 which propagate
+ to other functions like mp_invmod, mp_div, etc...
+ -- Sped up mp_exptmod_fast by using new code to find R mod m [e.g. B^n mod m]
+ -- minor fixes
+
+Jan 17th, 2003
+v0.12 -- re-wrote the majority of the makefile so its more portable and will
+ install via "make install" on most *nix platforms
+ -- Re-packaged all the source as seperate files. Means the library a single
+ file packagage any more. Instead of just adding "bn.c" you have to add
+ libtommath.a
+ -- Renamed "bn.h" to "tommath.h"
+ -- Changes to the manual to reflect all of this
+ -- Used GNU Indent to clean up the source
+
+Jan 15th, 2003
+v0.11 -- More subtle fixes
+ -- Moved to gentoo linux [hurrah!] so made *nix specific fixes to the make process
+ -- Sped up the montgomery reduction code quite a bit
+ -- fixed up demo so when building timing for the x86 it assumes ELF format now
+
+Jan 9th, 2003
+v0.10 -- Pekka Riikonen suggested fixes to the radix conversion code.
+ -- Added baseline montgomery and comba montgomery reductions, sped up exptmods
+ [to a point, see bn.h for MONTGOMERY_EXPT_CUTOFF]
+
+Jan 6th, 2003
+v0.09 -- Updated the manual to reflect recent changes. :-)
+ -- Added Jacobi function (mp_jacobi) to supplement the number theory side of the lib
+ -- Added a Mersenne prime finder demo in ./etc/mersenne.c
+
+Jan 2nd, 2003
+v0.08 -- Sped up the multipliers by moving the inner loop variables into a smaller scope
+ -- Corrected a bunch of small "warnings"
+ -- Added more comments
+ -- Made "mtest" be able to use /dev/random, /dev/urandom or stdin for RNG data
+ -- Corrected some bugs where error messages were potentially ignored
+ -- add etc/pprime.c program which makes numbers which are provably prime.
+
+Jan 1st, 2003
+v0.07 -- Removed alot of heap operations from core functions to speed them up
+ -- Added a root finding function [and mp_sqrt macro like from MPI]
+ -- Added more to manual
+
+Dec 31st, 2002
+v0.06 -- Sped up the s_mp_add, s_mp_sub which inturn sped up mp_invmod, mp_exptmod, etc...
+ -- Cleaned up the header a bit more
+
+Dec 30th, 2002
+v0.05 -- Builds with MSVC out of the box
+ -- Fixed a bug in mp_invmod w.r.t. even moduli
+ -- Made mp_toradix and mp_read_radix use char instead of unsigned char arrays
+ -- Fixed up exptmod to use fewer multiplications
+ -- Fixed up mp_init_size to use only one heap operation
+ -- Note there is a slight "off-by-one" bug in the library somewhere
+ without the padding (see the source for comment) the library
+ crashes in libtomcrypt. Anyways a reasonable workaround is to pad the
+ numbers which will always correct it since as the numbers grow the padding
+ will still be beyond the end of the number
+ -- Added more to the manual
+
+Dec 29th, 2002
+v0.04 -- Fixed a memory leak in mp_to_unsigned_bin
+ -- optimized invmod code
+ -- Fixed bug in mp_div
+ -- use exchange instead of copy for results
+ -- added a bit more to the manual
+
+Dec 27th, 2002
+v0.03 -- Sped up s_mp_mul_high_digs by not computing the carries of the lower digits
+ -- Fixed a bug where mp_set_int wouldn't zero the value first and set the used member.
+ -- fixed a bug in s_mp_mul_high_digs where the limit placed on the result digits was not calculated properly
+ -- fixed bugs in add/sub/mul/sqr_mod functions where if the modulus and dest were the same it wouldn't work
+ -- fixed a bug in mp_mod and mp_mod_d concerning negative inputs
+ -- mp_mul_d didn't preserve sign
+ -- Many many many many fixes
+ -- Works in LibTomCrypt now :-)
+ -- Added iterations to the timing demos... more accurate.
+ -- Tom needs a job.
+
+Dec 26th, 2002
+v0.02 -- Fixed a few "slips" in the manual. This is "LibTomMath" afterall :-)
+ -- Added mp_cmp_mag, mp_neg, mp_abs and mp_radix_size that were missing.
+ -- Sped up the fast [comba] multipliers more [yahoo!]
+
+Dec 25th,2002
+v0.01 -- Initial release. Gimme a break.
+ -- Todo list,
+ add details to manual [e.g. algorithms]
+ more comments in code
+ example programs
