Kenny * generic/tclStrToD.c (SetPrecisionLimits, TclDoubleDigits): [Bug 3124675]: Added meaningless initialization of 'i', 'ilim' and 'ilim1' to silence warnings from the C compiler about possible use of uninitialized variables, Added a panic to the 'switch' that assigns them, to assert that the 'default' case is impossible. 2010-12-01 Jan Nijtmans * generic/tclBasic.c: Fix gcc 64-bit warnings: cast from pointer to * generic/tclHash.c: integer of different size. * generic/tclTest.c: * generic/tclThreadTest.c: * generic/tclStrToD.c: Fix gcc(-4.5.2) warning: 'static' is not at beginning of declaration. * generic/tclPanic.c: Allow Tcl_Panic() to enter the debugger on win32 * generic/tclCkalloc.c: Use Tcl_Panic() in stead of duplicating the code. 2010-11-30 Jeff Hobbs * generic/tclInt.decls, generic/tclInt.h, generic/tclIntDecls.h: * generic/tclStubInit.c: TclFormatInt restored at slot 24 * generic/tclUtil.c (TclFormatInt): restore TclFormatInt func from 2005-07-05 macro-ization.

Kenny * generic/tclMain.c: Added missing conditional on _WIN32 around code that messes around with the definition of _UNICODE, to correct a badly broken Unix build from Jan's last commit. 2010-11-04 Jan Nijtmans * generic/tclDecls.h: [FRQ 491789]: "setargv() doesn't support a * generic/tclMain.c: unicode cmdline" implemented for Tcl on MSVC++ * doc/Tcl_Main.3: * win/tclAppInit.c: * win/makefile.vc: * win/Makefile.in: * win/tclWin32Dll.c: Eliminate minor MSVC warning TCHAR -> char conversion 2010-11-04 Reinhard Max * tests/socket.test: Run the socket tests three times with the address family set to any, inet, and inet6 respectively.

It was used for an ancient dummy reference to Tcl_LinkVar(), but that's already gone since 2002-05-29. 2010-04-29 Miguel Sofer * generic/tclCompExpr.c: Slight change in the literal sharing * generic/tclCompile.c: mechanism to avoid shimmering of * generic/tclCompile.h: command names. * generic/tclLiteral.c: 2010-04-29 Andreas Kupries * library/platform/platform.tcl: Another stab at getting the /lib, * library/platform/pkgIndex.tcl: /lib64 difference right for linux. * unix/Makefile.in: Package updated to version 1.0.7. * win/Makefile.in: 2010-04-29 Kevin B.

Fellows * generic/tclBinary.c (TclAppendBytesToByteArray): [Bug 2992970]: Make * generic/tclStringObj.c (Tcl_AppendObjToObj): an append of a byte array to another into an efficent operation. The problem was the (lack of) a proper growth management strategy for the byte array. 2010-04-29 Jan Nijtmans * compat/dirent2.h: Include "tcl.h", not , like everywhere * compat/dlfcn.h: else, to ensure that the version in the Tcl * compat/stdlib.h: distribution is used, not some version from * compat/string.h: somewhere else. * compat/unistd.h: 2010-04-28 Jan Nijtmans * win/Makefile.in: Remove unused @MAN2TCLFLAGS@ * win/tclWinPort.h: Move include from tclInt.h to * generic/tclInt.h: tclWinPort.h, and eliminate unneeded * generic/tclEnv.c: , and , which are already in tclInt.h * generic/regcustom.h: Move "tclInt.h" from regcustom.h up to * generic/regex.h: regex.h. * generic/tclAlloc.c: Unneeded include. * generic/tclExecute.c: Fix gcc warning: comparison between signed and unsigned. 2010-04-28 Donal K. Fellows * generic/tclInt.h (TclIsVarDirectUnsettable): Corrected flags so that deletion of traces is not optimized out... * generic/tclExecute.c (ExecuteExtendedBinaryMathOp) (TclCompareTwoNumbers,ExecuteExtendedUnaryMathOp,TclExecuteByteCode): [Patch 2981677]: Move the less common arithmetic operations (i.e., exponentiation and operations on non-longs) out of TEBC for a big drop in the overall size of the stack frame for most code. Net effect on speed is minimal (slightly faster overall in tclbench). Also extended the number of places where TRESULT handling is replaced with a jump to dedicated code. 2010-04-27 Donal K. Fellows * generic/tclExecute.c (TclExecuteByteCode): Rearrange location of an assignment to shorten the object code. 2010-04-27 Jan Nijtmans * generic/tclIOUtil.c (Tcl_FSGetNativePath): [Bug 2992292]: tclIOUtil.c assignment type mismatch compiler warning * generic/regguts.h: If tclInt.h or tclPort.h is already * generic/tclBasic.c: included, don't include * generic/tclExecute.c: again.

Kenny * unix/tclLoadDl.c (FindSymbol): [Bug 2992295]: Simplified the logic so that the casts added in Donal Fellows's change for the same bug are no longer necessary. 2010-04-26 Donal K. Fellows * unix/tclLoadDl.c (FindSymbol): [Bug 2992295]: Added an explicit cast because auto-casting between function and non-function types is never naturally warning-free. * generic/tclStubInit.c: Add a small amount of gcc-isms (with #ifdef * generic/tclOOStubInit.c: guards) to ensure that warnings are issued when these files are older than the various *.decls files. 2010-04-25 Miguel Sofer * generic/tclBasic.c: Add unsupported [yieldm] command.

Add fallback in tcl.h, so TCHAR is available in win32 always. 2010-04-15 Donal K. Fellows * doc/try.n: [Bug 2987551]: Fix typo. 2010-04-14 Andreas Kupries * library/platform/platform.tcl: Linux platform identification: * library/platform/pkgIndex.tcl: Check /lib64 for existence of files * unix/Makefile.in: matching libc* before accepting it as base * win/Makefile.in: directory. This can happen on weirdly installed 32bit systems which have an empty or partially filled /lib64 without an actual libc.

Fellows * generic/tclCompCmdsSZ.c (TclSubstCompile): If the first token does not result in a *guaranteed* push of a Tcl_Obj on the stack, we must push an empty object. Otherwise it is possible to get to a 'concat1' or 'done' without enough values on the stack, resulting in a crash. Thanks to Joe Mistachkin for identifying a script that could trigger this case. 2010-04-07 Donal K. Fellows * doc/catch.n, doc/info.n, doc/return.n: Formatting. 2010-04-06 Donal K.

Principal changes: * Use do { ... } while (0) in macros * Avoid shadowing one local variable with another * Use clearer 'foo.bar++;' instead of '++foo.bar;' where result not required (i.e., semantically equivalent); clarity is increased because it is bar that is incremented, not foo. * Follow Engineering Manual rules on spacing and declarations 2010-03-04 Donal K. Fellows * generic/tclOO.c (ObjectRenamedTrace): [Bug 2962664]: Add special handling so that when the class of classes is deleted, so is the class of objects. Immediately. * generic/tclOOInt.h (ROOT_CLASS): Add new flag for specially marking the root class. Simpler and more robust than the previous technique. 2010-03-04 Jan Nijtmans * generic/tclGetDate.y: 3 unnecessary MODULE_SCOPE * generic/tclDate.c: symbols * generic/tclStubLib.c: Split tommath stub lib * generic/tclTomMathStubLib.c: in separate file. * win/makefile.bc: * win/Makefile.in: * win/makefile.vc: * win/tcl.dsp: * unix/Makefile.in: * unix/tcl.m4: Cygwin only gives warning * unix/configure: using -fvisibility=hidden * compat/strncasecmp.c: A few more const's * compat/strtod.c: * compat/strtoul.c: 2010-03-03 Andreas Kupries * doc/refchan.n: Followup to ChangeLog entry 2009-10-07 (generic/tclIORChan.c). Fixed the documentation to explain that errno numbers are operating system dependent, and reworked the associated example. 2010-03-02 Jan Nijtmans * unix/tcl.m4: [FRQ 2959069]: Support for -fvisibility=hidden * unix/configure (regenerated with autoconf-2.59) 2010-03-01 Alexandre Ferrieux * unix/tclUnixSock.c: Refrain from a possibly lengthy reverse-DNS lookup on 0.0.0.0 when calling [fconfigure -sockname] on an universally-bound (default) server socket. * generic/tclIndexObj.c: fix [AT 86258]: special-casing of empty tables when generating error messages for [::tcl::prefix match]. 2010-02-28 Donal K. Fellows * generic/tclCmdIL.c: More additions of {TCL LOOKUP} error-code generation to various subcommands of [info] as part of long-term project to classify all Tcl's generated errors. 2010-02-28 Jan Nijtmans * generic/tclStubInit.c: [Bug 2959713]: Link error with gcc 4.1 2010-02-27 Donal K. Fellows * generic/tclCmdMZ.c (StringFirstCmd, StringLastCmd): [Bug 2960021]: Only search for the needle in the haystack when the needle isn't larger than the haystack. Prevents an odd crash from sometimes happening when things get mixed up (a common programming error). * generic/tclMain.c (Tcl_Main): [Bug 801429]: Factor out the holding of the client-installed main loop function into thread-specific data. ***POTENTIAL INCOMPATIBILITY*** Code that previously tried to set the main loop from another thread will now fail. On the other hand, there is a fairly high probability that such programs would have been failing before due to the lack of any kind of inter-thread memory barriers guarding accesses to this part of Tcl's state. 2010-02-26 Donal K. Fellows * generic/tclCompCmds.c: Split this file into two pieces to make it * generic/tclCompCmdsSZ.c: easier to work with. It's still two very long files even after the split. 2010-02-26 Reinhard Max * doc/safe.n: Name the installed file after the command it documents. Use "Safe Tcl" instead of the "Safe Base", "Safe Tcl" mixture. 2010-02-26 Donal K. Fellows * unix/Makefile.in (NATIVE_TCLSH): Added this variable to allow for better control of what tclsh to use for various scripts when doing cross compiling. An imperfect solution, but works. * unix/installManPage: Remap non-alphanumeric sequences in filenames to single underscores (especially colons). 2010-02-26 Pat Thoyts * tests/zlib.test: Add tests for [Bug 2818131] which was crashing with mismatched zlib algorithms used in combination with gets. This issue has been fixed by Andreas's last commit. 2010-02-25 Jan Nijtmans * generic/tclHash.c: [FRQ 2958832]: Further speed-up of the * generic/tclLiteral.c: ouster-hash function. * generic/tclObj.c: * generic/tclCkalloc.c: Eliminate various unnecessary (ClientData) * generic/tclTest.c: type casts. * generic/tclTestObj.c: * generic/tclTestProcBodyObj.c: * unix/tclUnixTest.c: * unix/tclUnixTime.c: * unix/tclXtTest.c: 2010-02-24 Donal K. Fellows * generic/tclDictObj.c (SetDictFromAny): Prevent the list<->dict * generic/tclListObj.c (SetListFromAny): conversion code from taking too many liberties. Stops loss of duplicate keys in some scenarios. Many thanks to Jean-Claude Wippler for finding this. * generic/tclExecute.c (TclExecuteByteCode): Reduce ifdef-fery and size of activation record. More variables shared across instructions than before. * doc/socket.n: [Bug 2957688]: Clarified that [socket -server] works with a command prefix. Extended example to show this in action. 2010-02-22 Andreas Kupries * generic/tclZlib.c (ZlibTransformInput): [Bug 2762041]: Added a hack to work around the general problem, early EOF recognition based on the base-channel, instead of the data we have ready for reading in the transform. Long-term we need a proper general fix (likely tracking EOF on each level of the channel stack), with attendant complexity. Furthermore, Z_BUF_ERROR can be ignored, and must be when feeding the zlib code with single characters. 2010-02-22 Jan Nijtmans * unix/tclUnixPort.h: Remove unnecessary EXTERN's, which already are in the global stub table. * unix/configure.in: Use @EXEEXT@ in stead of @EXT_SUFFIX@ * unix/tcl.m4: * unix/Makefile.in: Use -DBUILD_tcl for CYGWIN * unix/configure: (regenerated) * unix/dltest/pkg*.c: Use EXTERN to control CYGWIN exported symbols * generic/tclCmdMZ.c: Remove some unnecessary type casts. * generic/tclCompCmds.c: * generic/tclTest.c: * generic/tclUtil.c: 2010-02-21 Mo DeJong * tests/regexp.test: Add test cases back ported from Jacl regexp work. 2010-02-21 Jan Nijtmans * generic/tclDate.c: Some more const tables. * generic/tclGetDate.y: * generic/regc_lex.c: * generic/regerror.c: * generic/tclStubLib.c: * generic/tclBasic.c: Fix [Bug 2954959] expr abs(0.0) is -0.0 * tests/expr.test: 2010-02-20 Donal K. Fellows * generic/tclCompCmds.c (TclCompileStringLenCmd): Make [string length] of a constant string be handled better (i.e., handle backslashes too). 2010-02-19 Stuart Cassoff * tcl.m4: Correct compiler/linker flags for threaded builds on OpenBSD. * configure: (regenerated). 2010-02-19 Donal K. Fellows * unix/installManPage: [Bug 2954638]: Correct behaviour of manual page installer. Also added armouring to check that assumptions about the initial state are actually valid (e.g., look for existing input file). 2010-02-17 Donal K. Fellows * generic/tclHash.c (HashStringKey): Restore these hash functions * generic/tclLiteral.c (HashString): to use the classic algorithm. * generic/tclObj.c (TclHashObjKey): Community felt normal case speed to be more important than resistance to malicious cases. For now, hashes that need to deal with the malicious case can use a custom hash table and install their own hash function, though that is not functionality exposed to the script level. * generic/tclCompCmds.c (TclCompileDictUpdateCmd): Stack depth must be correctly described when compiling a body to prevent crashes in some debugging modes. 2010-02-16 Jan Nijtmans * generic/tclInt.h: Change order of various struct members, fixing potential binary incompatibility with Tcl 8.5 2010-02-16 Donal K. Fellows * unix/configure.in, generic/tclIOUtil.c (Tcl_Stat): Updated so that we do not assume that all unix systems have the POSIX blkcnt_t type, since OpenBSD apparently does not. * generic/tclLiteral.c (HashString): Missed updating to FNV in one place; the literal table (a copy of the hash table code...) 2010-02-15 Jan Nijtmans * tools/genStubs.tcl: Reverted earlier rename from tcl*Stubs to * generic/tclBasic.c: tcl*ConstStubs, it's not necessary at all. * generic/tclOO.c: * generic/tclTomMathInterface.c: * generic/tclStubInit.c: (regenerated) * generic/tclOOStubInit.c: (regenerated) * generic/tclEnsemble.c:Fix signed-unsigned mismatch * win/tclWinInt.h: make tclWinProcs "const" * win/tclWin32Dll.c: * win/tclWinFCmd.c: Eliminate all internal Tcl_WinUtfToTChar * win/tclWinFile.c: and Tcl_WinTCharToUtf calls, needed * win/tclWinInit.c: for mslu support. * win/tclWinLoad.c: * win/tclWinPipe.c: * win/tclWinSerial.c: * win/.cvsignore: * compat/unicows/readme.txt: [FRQ 2819611]: Add first part of MSLU * compat/unicows/license.txt: support. * compat/unicows/unicows.lib: 2010-02-15 Donal K. Fellows * generic/tclOO.c (AllocObject, SquelchedNsFirst, ObjectRenamedTrace): * generic/tclNamesp.c (Tcl_DeleteNamespace): [Bug 2950259]: Revised the namespace deletion code to provide an additional internal callback that gets triggered early enough in namespace deletion to allow TclOO destructors to run sanely. Adjusted TclOO to take advantage of this, so making tearing down an object by killing its namespace appear to work seamlessly, which is needed for Itcl. (Note that this is not a feature that will ever be backported to 8.5, and it remains not a recommended way of deleting an object.) 2010-02-13 Donal K. Fellows * generic/tclCompCmds.c (TclCompileSwitchCmd): Divided the [switch] compiler into three pieces (after the model of [try]): a parser, an instruction-issuer for chained tests, and an instruction-issuer for jump tables. * generic/tclEnsemble.c: Split the ensemble engine out into its own file rather than keeping it mashed together with the namespace code. 2010-02-12 Jan Nijtmans * win/tcl.m4: Use -pipe for gcc on win32 * win/configure: (mingw/cygwin) (regenerated) * win/.cvsignore: Add .lib, .exp and .res here 2010-02-11 Mo DeJong * tests/list.test: Add tests for explicit \0 in a string argument to the list command. 2010-02-11 Donal K. Fellows * generic/tclIOCmd.c (Tcl_OpenObjCmd): [Bug 2949740]: Make sure that we do not try to put a NULL pipeline channel into binary mode. 2010-02-11 Mo DeJong [Bug 2826551, Patch 2948425]: Assorted regexp bugs related to -all, -line and -start options and newlines. * generic/tclCmdMZ.c (Tcl_RegexpObjCmd): If -offset is given, treat it as the start of the line if the previous character was a newline. Fix nasty edge case where a zero length match would not advance the index. * tests/regexp.test: Add regression tests back ported from Jacl. Checks for a number of issues related to -line and newline handling. A few of tests were broken before the patch and continue to be broken, marked as knownBug. 2010-02-11 Donal K. Fellows * generic/tclOO.c (ObjectRenamedTrace): [Bug 2949397]: Prevent destructors from running on the two core class objects when the whole interpreter is being destroyed. 2010-02-09 Donal K. Fellows * generic/tclCompCmds.c (TclCompileTryCmd, IssueTryInstructions) (IssueTryFinallyInstructions): Added compiler for the [try] command. It is split into three pieces that handle the parsing of the tokens, the issuing of instructions for finally-free [try], and the issuing of instructions for [try] with finally; there are enough differences between the all cases that it was easier to split the code rather than have a single function do the whole thing. 2010-02-09 Alexandre Ferrieux * tools/genStubs.tcl: Remove dependency on 8.5+ idiom "in" in expressions. 2010-02-08 Donal K. Fellows * generic/tclZlib.c (Tcl_ZlibDeflate, Tcl_ZlibInflate): [Bug 2947783]: Make sure that the result is an unshared object before appending to it so that nothing crashes if it is shared (use in Tcl code was not affected by this, but use from C was an issue). 2010-02-06 Donal K. Fellows * generic/tclHash.c (HashStringKey): Replace Tcl's crusty old hash * generic/tclObj.c (TclHashObjKey): function with the algorithm due to Fowler, Noll and Vo. This is slightly faster (assuming the presence of hardware multiply) and has somewhat better distribution properties of the resulting hash values. Note that we only ever used the 32-bit version of the FNV algorithm; Tcl's core hash engine assumes that hash values are simple unsigned ints. ***POTENTIAL INCOMPATIBILITY*** Code that depends on hash iteration order (especially tests) may well be disrupted by this. Where a definite order is required, the fix is usually to just sort the results after extracting them from the hash. Where this is insufficient, the code that has ceased working was always wrong and was only working by chance. 2010-02-05 Donal K. Fellows * generic/tclCompCmds.c (TclCompileErrorCmd): Added compilation of the [error] command. No new bytecodes. 2010-02-05 Jan Nijtmans * tools/genStubs.tcl: Follow-up to earlier commit today: Eliminate the need for an extra Stubs Pointer for adressing a static stub table: Just change the exported table from static to MODULE_SCOPE. * generic/tclBasic.c * generic/tclOO.c * generic/tclTomMathInterface.c * generic/tcl*Decls.h (regenerated) * generic/tclStubInit.c (regenerated) * generic/tclOOStubInit.c (regenerated) * generic/tclTest.c (minor formatting) 2010-02-05 Donal K. Fellows * generic/tclVar.c: More consistency in errorcode generation. * generic/tclOOBasic.c (TclOO_Object_Destroy): Rewrote to be NRE-aware when calling destructors. Note that there is no guarantee that destructors will always be called in an NRE context; that's a feature of the 'destroy' method only. * generic/tclEncoding.c: Add 'const' to many function-internal vars that are never pointing to things that are written to. 2010-02-05 Jan Nijtmans * tools/genStubs.tcl: Follow-up to [2010-01-29] commit: prevent space within stub table function parameters if the parameter type is a pointer. * win/tclWinInt.h: Minor Formatting * generic/tcl.h: VOID -> void and other formatting * generic/tclInt.h: Minor formatting * generic/tclInt.decls: Change signature of TclNRInterpProcCore, * generic/tclOO.decls: and TclOONewProc(Instance|)MethodEx, * generic/tclProc.c: indicating that errorProc is a function, * generic/tclOOMethod.c:pointer, and other formatting * generic/tcl*Decls.h: (regenerated) * generic/tclVar.c: gcc warning(line 3703): 'pattern' may be used uninitialized in this function gcc warning(line 3788): 'matched' may be used uninitialized in this function 2010-02-04 Donal K. Fellows * generic/tclVar.c: Added more use of error-codes and reduced the stack overhead of older interfaces. (ArrayGetCmd): Stop silly crash when using a trivial pattern due to error in conversion to ensemble. (ArrayNamesCmd): Use the object RE interface for faster matching. 2010-02-03 Donal K. Fellows * generic/tclVar.c (ArrayUnsetCmd): More corrections. 2010-02-02 Donal K. Fellows * generic/tclVar.c: Turned the [array] command into a true ensemble. * generic/tclOO.c (AllocObject, MyDeleted): A slightly faster way to handle the deletion of [my] is with a standard delete callback. This is because it doesn't require an additional memory allocation during object creation. Also reduced the amount of string manipulation performed during object creation to further streamline memory handling; this is not backported to the 8.5 package as it breaks a number of abstractions. * generic/tclOOBasic.c (TclOO_Object_Destroy): [Bug 2944404]: Do not crash when a destructor deletes the object that is executing that destructor. 2010-02-01 Donal K. Fellows * generic/tclVar.c (Tcl_ArrayObjCmd): [Bug 2939073]: Stop the [array unset] command from having dangling pointer problems when an unset trace deletes the element that is going to be processed next. Many thanks to Alexandre Ferrieux for the bulk of this fix. * generic/regexec.c (ccondissect, crevdissect): [Bug 2942697]: Rework these functions so that certain pathological patterns are matched much more rapidly. Many thanks to Tom Lane for dianosing this issue and providing an initial patch. 2010-01-30 Donal K. Fellows * generic/tclCompile.c (tclInstructionTable): Bytecode instructions * generic/tclCompCmds.c (TclCompileUnsetCmd): to allow the [unset] * generic/tclExecute.c (TclExecuteByteCode): command to be compiled with the compiler being a complete compilation for all compile-time decidable uses. * generic/tclVar.c (TclPtrUnsetVar): Var reference version of the code to unset a variable. Required for INST_UNSET bytecodes. 2010-01-29 Jan Nijtmans * generic/tcl.h: [Bug 2942081]: Reverted Tcl_ThreadDataKey type change Changed some Tcl_CallFrame fields from "char *" to "void *". This saves unnecessary space on Cray's (and it's simply more correct). * tools/genStubs.tcl: No longer generate a space after "*" and immediately after a function name, so the format of function definitions in tcl*Decls.h match all other tcl*.h header files. * doc/ParseArgs.3: Change Tcl_ArgvFuncProc, Tcl_ArgvGenFuncProc * generic/tcl.h: and GetFrameInfoValueProc to be function * generic/tclInt.h: definitions, not pointers, for consistency * generic/tclOOInt.h: with all other Tcl function definitions. * generic/tclIndexObj.c: * generic/regguts.h: CONST -> const * generic/tcl.decls: Formatting * generic/tclTomMath.decls: Formatting * generic/tclDecls.h: (regenerated) * generic/tclIntDecls.h: * generic/tclIntPlatDecls.h: * generic/tclOODecls.h: * generic/tclOOIntDecls.h: * generic/tclPlatDecls.h: * generic/tclTomMathDecls.h: 2010-01-28 Donal K. Fellows * generic/tclOOBasic.c (TclOO_Object_Destroy): Move the execution of destructors to a point where they can produce an error. This will not work for all destructors, but it does mean that more failing calls of them will be caught. * generic/tclOO.c (AllocObject, MyDeletedTrace, ObjectRenamedTrace): (ObjectNamespaceDeleted): Stop various ways of getting at commands with dangling pointers to the object. Also increases the reliability of calling of destructors (though most destructors won't benefit; when an object is deleted namespace-first, its destructors are not run in a nice state as the namespace is partially gone). 2010-01-25 Jan Nijtmans * generic/tclOOStubInit.c: Remove double includes (which causes a * generic/tclOOStubLib.c: warning in CYGWIN compiles) * unix/.cvsignore: add confdefs.h 2010-01-22 Donal K. Fellows * doc/proc.n: [Bug 1970629]: Define a bit better what the current namespace of a procedure is. 2010-01-22 Jan Nijtmans * generic/tclInt.decls: Don't use DWORD and HANDLE here. * generic/tclIntPlatDecls.h: * generic/tcl.h: Revert [2009-12-21] change, instead * generic/tclPort.h: resolve the CYGWIN inclusion problems by * win/tclWinPort.h: re-arranging the inclusions at other places. * win/tclWinError.c * win/tclWinPipe.c * win/tcl.m4: Make cygwin configuration error into * win/configure.in: a warning: CYGWIN compilation works * win/configure: although there still are test failures. 2010-01-22 Donal K. Fellows * generic/tclExecute.c (TclExecuteByteCode): Improve error code generation from some of the tailcall-related bits of TEBC. 2010-01-21 Miguel Sofer * generic/tclCompile.h: NRE-enable direct eval on BC spoilage * generic/tclExecute.c: [Bug 2910748] * tests/nre.test: 2010-01-19 Donal K. Fellows * doc/dict.n: [Bug 2929546]: Clarify just what [dict with] and [dict update] are doing with variables. 2010-01-18 Andreas Kupries * generic/tclIO.c (CreateScriptRecord): [Bug 2918110]: Initialize the EventScriptRecord (esPtr) fully before handing it to Tcl_CreateChannelHandler for registration. Otherwise a reflected channel calling 'chan postevent' (== Tcl_NotifyChannel) in its 'watchProc' will cause the function 'TclChannelEventScriptInvoker' to be run on an uninitialized structure. 2010-01-18 Donal K. Fellows * generic/tclStringObj.c (Tcl_AppendFormatToObj): [Bug 2932421]: Stop the [format] command from causing argument objects to change their internal representation when not needed. Thanks to Alexandre Ferrieux for this fix. 2010-01-13 Donal K. Fellows * tools/tcltk-man2html.tcl: More factoring out of special cases * tools/tcltk-man2html-utils.tcl: so that they are described outside the engine file. Now there is only one real set of special cases in there, to handle the .SO/.OP/.SE directives. 2010-01-13 Jan Nijtmans * generic/tcl.h: Fix TCL_LL_MODIFIER for Cygwin * generic/tclEnv.c: Fix CYGWIN compilation problems, * generic/tclInt.h: and remove some unnecessary * generic/tclPort.h: double includes. * generic/tclPlatDecls.h: * win/cat.c: * win/tclWinConsole.c: * win/tclWinFCmd.c: * win/tclWinFile.c: * win/tclWinPipe.c: * win/tclWinSerial.c: * win/tclWinThrd.c: * win/tclWinPort.h: Put win32 includes first * unix/tclUnixChan.c: Forgot one CONST change 2010-01-12 Donal K. Fellows * tools/tcltk-man2html.tcl: Make the generation of the list of things to process the docs from simpler and more flexible. Also factored out the lists of special cases. 2010-01-10 Jan Nijtmans * win/tclWinDde.c: VC++ 6.0 doesn't have * win/tclWinReg.c: PDWORD_PTR * win/tclWinThrd.c: Fix various minor gcc warnings. * win/tclWinTime.c: * win/tclWinConsole.c: Put channel type definitions * win/tclWinChan.c: in static const memory * win/tclWinPipe.c: * win/tclWinSerial.c: * win/tclWinSock.c: * generic/tclIOGT.c: * generic/tclIORChan.c: * generic/tclIORTrans.c: * unix/tclUnixChan.c: * unix/tclUnixPipe.c: * unix/tclUnixSock.c: * unix/configure: (regenerated with autoconf 2.59) * tests/info.test: Make test independant from tcltest implementation. 2010-01-10 Donal K. Fellows * tests/namespace.test (namespace-51.17): [Bug 2898722]: Demonstrate that there are still bugs in the handling of resolution epochs. This bug is not yet fixed. * tools/tcltk-man2html.tcl: Split the man->html converter into * tools/tcltk-man2html-utils.tcl: two pieces for easier maintenance. Also made it much less verbose in its printed messages by default. 2010-01-09 Donal K. Fellows * tools/tcltk-man2html.tcl: Added basic support for building the docs for contributed packages into the HTML versions. Prompted by question on Tcler's Chat by Tom Krehbiel. Note that there remain problems in the documentation generated due to errors in the contributed docs. 2010-01-05 Don Porter * generic/tclPathObj.c (TclPathPart): [Bug 2918610]: Correct * tests/fileName.test (filename-14.31): inconsistency between the string rep and the intrep of a path value created by [file rootname]. Thanks to Vitaly Magerya for reporting. 2010-01-03 Donal K.

Added a test for this * generic/tclNamesp.c: leak, and also a test for leaks on namespace * tests/coroutine.test: deletion. * tests/namespace.test: 2009-12-30 Donal K. Fellows * library/safe.tcl (AliasSource): [Bug 2923613]: Make the safer * tests/safe.test (safe-8.9): [source] handle a [return] at the end of the file correctly. 2009-12-30 Miguel Sofer * library/init.tcl (unknown): [Bug 2824981]: Fix infinite recursion of ::unknown when [set] is undefined. 2009-12-29 Donal K. Fellows * generic/tclHistory.c (Tcl_RecordAndEvalObj): Reduce the amount of allocation and deallocation of memory by caching objects in the interpreter assocData table. * generic/tclObj.c (Tcl_GetCommandFromObj): Rewrite the logic so that it does not require making assignments part way through an 'if' condition, which was deeply unclear. * generic/tclInterp.c (Tcl_MakeSafe): [Bug 2895741]: Make sure that the min() and max() functions are supported in safe interpreters. 2009-12-29 Pat Thoyts * generic/tclBinary.c: [Bug 2922555]: Handle completely invalid input * tests/binary.test: to the decode methods. 2009-12-28 Donal K.

Fellows * tools/tcltk-man2html.tcl (long-toc, cross-reference): [FRQ 2897296]: Added cross links to sections within manual pages. 2009-12-11 Miguel Sofer * generic/tclBasic.c: [Bug 2806407]: Full nre-enabling of coroutines * generic/tclExecute.c: * generic/tclBasic.c: Small cleanup * generic/tclExecute.c: Fix panic in http11.test caused by buggy earlier commits in coroutine management. 2009-12-10 Andreas Kupries * generic/tclObj.c (TclContinuationsEnter): [Bug 2895323]: Updated comments to describe when the function can be entered for the same Tcl_Obj* multiple times. This is a continuation of the 2009-11-10 entry where a memory leak was plugged, but where not sure if that was just a band-aid to paper over some other error. It isn't, this is a legal situation. 2009-12-10 Miguel Sofer * generic/tclBasic.c: Reducing the # of moving parts for coroutines * generic/tclExecute.c: by delegating more to tebc; eliminate the special coroutine CallFrame. 2009-12-09 Andreas Kupries * generic/tclIO.c: [Bug 2901998]: Applied Alexandre Ferrieux's patch fixing the inconsistent buffered I/O. Tcl's I/O now flushes buffered output before reading, discards buffered input before writing, etc. 2009-12-09 Miguel Sofer * generic/tclBasic.c: Ensure right lifetime of varFrame's (objc,objv) for coroutines. * generic/tclExecute.c: Code regrouping 2009-12-09 Donal K.

Kenny * win/tclAppInit.c (Tcl_AppInit): [Bug 2902965]: Reverted Jan's change that added a call to Tcl_InitStubs. The 'tclsh' and 'tcltest' programs are providers, not consumers of the Stubs table, and should not link with the Stubs library, but only with the main Tcl library. (In any case, the presence of Tcl_InitStubs broke the build.) 2009-11-27 Donal K.

BUMP VERSION OF TCLOO TO 0.6.2. Too many people need accumulated small versions and bugfixes, so the version-bump removes confusion. * generic/tclOOBasic.c (TclOO_Object_LinkVar): [Bug 2903811]: Remove unneeded restrictions on who can usefully call this method. 2009-11-26 Donal K. Fellows * unix/Makefile.in: Add .PHONY rules and documentation to preemptively stop trouble that plagued Tk from hitting Tcl too, and to make the overall makefile easier to understand. Some reorganization too to move related rules closer together. 2009-11-26 Jan Nijtmans * win/Makefile.in: [Bug 2902965]: Fix stub related changes that * win/makefile.vc: caused tclkit build to break. * win/tclAppInit.c * unix/tcl.m4 * unix/Makefile.in * unix/tclAppInit.c * unix/configure: (regenerated) 2009-11-25 Kevin B. Kenny * win/Makefile.in: Added a 'test-tcl' rule that is identical to 'test' except that it does not go spelunking in 'pkgs/'. (This rule has existed in unix/Makefile.in for some time.) 2009-11-25 Stuart Cassoff * unix/configure.in: [Patch 2892871]: Remove unneeded * unix/tcl.m4: AC_STRUCT_TIMEZONE and use * unix/tclConfig.h.in: AC_CHECK_MEMBERS([struct stat.st_blksize]) * unix/tclUnixFCmd.c: instead of AC_STRUCT_ST_BLKSIZE. * unix/configure: Regenerated with autoconf-2.59. 2009-11-24 Andreas Kupries * library/tclIndex: Manually redone the part of tclIndex dealing with safe.tcl and tm.tcl. This part passes the testsuite. Note that automatic regeneration of this part is not possible because it wrongly puts 'safe::Setup' on the list, and wrongly leaves out 'safe::Log' which is more dynamically created than the generator expects. Further note that the file "clock.tcl" is explicitly loaded by "init.tcl", the first time the clock command is invoked. The relevant code can be found at line 172ff, roughly, the definition of the procedure 'clock'. This means none of the procedures of this file belong in the tclIndex. Another indicator that automatic regeneration of tclIndex is ill-advised. 2009-11-24 Donal K. Fellows * generic/tclOO.c (FinalizeAlloc, Tcl_NewObjectInstance): [Bug 2903011]: Make it an error to destroy an object in a constructor, and also make sure that an object is not deleted twice in the error case. 2009-11-24 Pat Thoyts * tests/fCmd.test: [Bug 2893771]: Teach [file stat] to handle locked * win/tclWinFile.c: files so that [file exists] no longer lies. 2009-11-23 Kevin Kenny * tests/fCmd.test (fCmd-30.1): Changed registry location of the 'My Documents' folder to the one that's correct for Windows 2000, XP, Server 2003, Vista, Server 2008, and Windows 7.

It seems that strchr is apparently a macro on AIX and reacts badly to pre-processor directives in its arguments. 2009-11-16 Alexandre Ferrieux * generic/tclEncoding.c: [Bug 2891556]: Fix and improve test to * generic/tclTest.c: detect similar manifestations in the future. * tests/encoding.test: Add tcltest support for finalization. 2009-11-15 Mo DeJong * win/tclWinDde.c: Avoid gcc compiler warning by explicitly casting DdeCreateStringHandle argument. 2009-11-12 Andreas Kupries * generic/tclIO.c (CopyData): [Bug 2895565]: Dropped bogosity which * tests/io.test: used the number of _written_ bytes or character to update the counters for the read bytes/characters.

Uneasy to test; might need specific channel drivers. Four-hands with aku. 2009-11-10 Pat Thoyts * tests/winFCmd.test: Cleanup directories that have been set chmod 000. On Windows7 and Vista we really have no access and these were getting left behind. A few tests were changed to reflect the intent of the test where setting a directory chmod 000 should prevent any modification. This restriction was ignored on XP but is honoured on Vista 2009-11-10 Andreas Kupries * generic/tclBasic.c: Plug another leak in TCL_EVAL_DIRECT evaluation. Forward port from Tcl 8.5 branch, change by Don Porter. * generic/tclObj.c: [Bug 2895323]: Plug memory leak in TclContinuationsEnter().

Added clause on structure type to prevent seg.faulting. Forward port from valgrinding the Tcl 8.5 branch. * tests/info.test: Resolve ambiguous resolution of variable "res". Forward port from 8.5 2009-11-08 Donal K. Fellows * doc/string.n (bytelength): Noted that this command is not a good thing to use, and suggested a better alternatve. Also factored out the description of the indices into its own section. 2009-11-07 Pat Thoyts * tests/fCmd.test: [Bug 2891026]: Exclude tests using chmod 555 directories on vista and win7. The current user has access denied and so cannot rename the directory without admin privileges. 2009-11-06 Andreas Kupries * library/safe.tcl (::safe::Setup): Added documentation of the contents of the state array. Also killed the 'InterpState' procedure with its upleveled variable/upvar combination, and replaced all uses with 'namespace upvar'. 2009-11-05 Andreas Kupries * library/safe.tcl: A series of patches which bring the SafeBase up to date with code guidelines, Tcl's features, also eliminating a number of inefficiencies along the way. (1) Changed all procedure names to be fully qualified. (2) Moved the procedures out of the namespace eval. Kept their locations. IOW, broke the namespace eval apart into small sections not covering the procedure definitions. (3) Reindented the code. Just lots of whitespace changes. Functionality unchanged. (4) Moved the multiple namespace eval's around. Command export at the top, everything else (var decls, argument parsing setup) at the bottom. (5) Moved the argument parsing setup into a procedure called when the code is loaded. Easier management of temporary data. (6) Replaced several uses of 'Set' with calls to the new procedure 'InterpState' and direct access to the per-slave state array. (7) Replaced the remaining uses of 'Set' and others outside of the path/token handling, and deleted a number of procedures related to state array access which are not used any longer. (8) Converted the path token system to cache normalized paths and path <-> token conversions. Removed more procedures not used any longer. Removed the test cases 4.3 and 4.4 from safe.test. They were testing the now deleted command "InterpStateName". (9) Changed the log command setup so that logging is compiled out completely when disabled (default). (10) Misc. cleanup. Inlined IsInterp into CheckInterp, its only user. Consistent 'return -code error' for error reporting. Updated to use modern features (lassign, in/ni, dicts). The latter are used to keep a reverse path -> token map and quicker check of existence. (11) Fixed [Bug 2854929]: Recurse into all subdirs under all TM root dirs and put them on the access path. 2009-11-02 Kevin B. Kenny * library/tzdata/Asia/Novokuznetsk: New tzdata locale for Kemerovo oblast', which now keeps Novosibirsk time and not Kranoyarsk time. * library/tzdata/Asia/Damascus: Syrian DST changes. * library/tzdata/Asia/Hong_Kong: Hong Kong historic DST corrections. Olson tzdata2009q. 2009-11-02 Donal K. Fellows * doc/object.n (DESCRIPTION): Substantive revision to make it clearer what the fundamental semantics of an object actually are. 2009-11-01 Joe Mistachkin * doc/Cancel.3: Minor cosmetic fixes. * win/makefile.vc: Make htmlhelp target work again. An extra set of double quotes around the definition of the HTML help compiler tool appears to be required. Previously, there was one set of double quotes around the definition of the tool and one around the actual invocation. This led to confusion because it was the only such tool path to include double quotes around its invocation. Also, it was somewhat inflexible in the event that somebody needed to override the tool command to include arguments. Therefore, even though it may look "wrong", there are now two double quotes on either side of the tool path definition. This fixes the problem that currently prevents the htmlhelp target from building and maintains flexibility in case somebody needs to override it via the command line or an environment variable. 2009-11-01 Joe English * doc/Eval.3, doc/Cancel.3: Move TIP#285 routines out of Eval.3 into their own manpage. 2009-10-31 Donal K. Fellows * generic/tclBasic.c (ExprRoundFunc): [Bug 2889593]: Correctly report the expected number of arguments when generating an error for round(). 2009-10-30 Pat Thoyts * tests/tcltest.test: When creating the notwritabledir we deny the current user access to delete the file. We must grant this right when we cleanup. Required on Windows 7 when the user does not automatically have administrator rights. 2009-10-29 Don Porter * generic/tcl.h: Changed the typedef for the mp_digit type from: typedef unsigned long mp_digit; 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 element to be actually used storing number data. Without this change bignums are over 50% wasted space on 64-bit systems. [Bug 2800740]. ***POTENTIAL INCOMPATIBILITY*** For 64-bit builds, callers of routines with (mp_digit) or (mp_digit *) arguments *will*, and callers of routines with (mp_int *) arguments *may* suffer both binary and stubs incompatibilities with Tcl releases 8.5.0 - 8.5.7. Such possibilities should be checked, and if such incompatibilities are present, suitable [package require] requirements on the Tcl release should be put in place to keep such built code [load]-ing only in Tcl interps that are compatible. 2009-10-29 Donal K. Fellows * tests/dict.test: Make variable-clean and simplify tests by utilizing the fact that dictionaries have defined orders. * generic/tclZlib.c (TclZlibCmd): Remove accidental C99-ism which reportedly makes the AIX native compiler choke. 2009-10-29 Kevin B. Kenny * library/clock.tcl (LocalizeFormat): * tests/clock.test (clock-67.1): [Bug 2819334]: Corrected a problem where '%%' followed by a letter in a format group could expand recursively: %%R would turn into %%H:%M:%S 2009-10-28 Don Porter * generic/tclLiteral.c: [Bug 2888044]: Fixed 2 bugs. * tests/info.test: First, as noted in the comments of the TclCleanupLiteralTable routine, since the teardown of the intrep of one Tcl_Obj can cause the teardown of others in the same table, the full table cleanup must be done with care, but the code did not contain the same care demanded in the comment. Second, recent additions to the info.test file had poor hygiene, leaving an array variable ::a lying around, which breaks later interp.test tests during a -singleproc 1 run of the test suite. 2009-10-28 Kevin B. Kenny * tests/fileName.test (fileName-20.[78]): Corrected poor test hygiene (failure to save and restore the working directory) that caused these two tests to fail on Windows (and [Bug 2806250] to be reopened). 2009-10-27 Don Porter * generic/tclPathObj.c: [Bug 2884203]: Missing refcount on cached normalized path caused crashes. 2009-10-27 Kevin B.

Also make the names of the continuation line information initialization and finalization functions more consistent. Patch supplied by Joe Mistachkin . * generic/tclIORChan.c (ErrnoReturn): Replace hardwired constant 11 with proper errno #define, EAGAIN. What was I thinking? The BSD's have a different errno assignment and break with the hardwired number. Reported by emiliano on the chat. 2009-10-06 Don Porter * generic/tclInterp.c (SlaveEval): Agressive stomping of internal reps was added as part of the NRE patch of 2008-07-13. This doesn't appear to actually be needed, and it hurts quite a bit when large lists lose their intreps and require reparsing. Thanks to Ashok Nadkarni for reporting the problem. * generic/tclTomMathInt.h (new): Public header tclTomMath.h had * generic/tclTomMath.h: dependence on private headers, breaking use * generic/tommath.h: by extensions [Bug 1941434]. 2009-10-05 Andreas Kupries * library/safe.tcl (AliasGlob): Fixed conversion of catch to try/finally, it had an 'on ok msg' branch missing, causing a silent error immediately, and bogus glob results, breaking search for Tcl modules. 2009-10-04 Daniel Steffen * macosx/tclMacOSXBundle.c: Workaround CF memory managment bug in * unix/tclUnixInit.c: Mac OS X 10.4 & earlier.

[Bugs 2557696 and 2557796]. 2009-09-28 Don Porter * generic/tclCmdMZ.c: Replaced TclProcessReturn() calls with * tests/error.test: Tcl_SetReturnOptions() calls as a simple fix for [Bug 2855247]. Thanks to Anton Kovalenko for the report and fix. Additional fixes for other failures demonstrated by new tests. 2009-09-27 Don Porter * tests/error.test (error-15.8.*): Coverage tests illustrating flaws in the propagation of return options by [try]. 2009-09-26 Donal K. Fellows * unix/tclooConfig.sh, win/tclooConfig.sh: [Bug 2026844]: Added dummy versions of tclooConfig.sh that make it easier to build extensions against both Tcl8.5+TclOO-standalone and Tcl8.6. 2009-09-24 Don Porter TIP #356 IMPLEMENTATION * generic/tcl.decls: Promote internal routine TclNRSubstObj() * generic/tclCmdMZ.c: to public Tcl_NRSubstObj(). Still needs docs. * generic/tclCompile.c: * generic/tclInt.h: * generic/tclDecls.h: make genstubs * generic/tclStubInit.c: 2009-09-23 Miguel Sofer * doc/namespace.n: the description of [namespace unknown] failed to mention [namespace path]: fixed.

Added additional simple test cases of basic regsub command. 2009-09-21 Don Porter * generic/tclCompile.c: Correct botch in the conversion of Tcl_SubstObj(). Thanks to Kevin Kenny for detection and report. 2009-09-17 Don Porter * generic/tclCompile.c: Re-implement Tcl_SubstObj() as a simple * generic/tclParse.c: wrapper around TclNRSubstObj(). This has * tests/basic.test: the effect of caching compiled bytecode in * tests/parse.test: the value to be substituted. Note that Tcl_SubstObj() now exists only for extensions. Tcl itself no longer makes any use of it. Note also that TclSubstTokens() is now reachable only by Tcl_EvalEx() and Tcl_ParseVar() so tests aiming to test its functioning needed adjustment to still have the intended effect. 2009-09-16 Alexandre Ferrieux * generic/tclObj.c: Extended ::tcl::unsupported::representation. 2009-09-11 Don Porter * generic/tclBasic.c: Completed the NR-enabling of [subst]. * generic/tclCmdMZ.c: [Bug 2314561]. * generic/tclCompCmds.c: * generic/tclCompile.c: * generic/tclInt.h: * tests/coroutine.test: * tests/parse.test: 2009-09-11 Donal K.

This is a partial solution to * generic/tclCompile.c: the need to NR-enable [subst] since bytecode * generic/tclCompile.h: execution is already NR-enabled. Two new * generic/tclExecute.c: bytecode instructions, INST_NOP and * generic/tclInt.h: INST_RETURN_CODE_BRANCH were added to support * generic/tclParse.c: the new routine. INST_RETURN_CODE_BRANCH is * tests/basic.test: likely to be useful in any future effort to * tests/info.test: add a bytecode compiler routine for [try]. * tests/parse.test: 2009-09-03 Donal K. Fellows * doc/LinkVar.3: [Bug 2844962]: Added documentation of issues relating to use of this API in a multi-threaded environment. 2009-09-01 Andreas Kupries * generic/tclIORTrans.c (ReflectInput): Remove error response to 0-result from method 'limit?' of transformations. Return the number of copied bytes instead, which is possibly nothing. The latter then triggers EOF handling in the higher layers, making the 0-result of limit? the way to inject artificial EOF's into the data stream. 2009-09-01 Don Porter * library/tcltest/tcltest.tcl: Bump to tcltest 2.3.2 after revision * library/tcltest/pkgIndex.tcl: to verbose error message. * unix/Makefile.in: * win/Makefile.in: 2009-08-27 Don Porter * generic/tclStringObj.c: [Bug 2845535]: A few more string overflow cases in [format]. 2009-08-25 Andreas Kupries * generic/tclBasic.c (Tcl_CreateInterp, Tcl_EvalTokensStandard) (Tcl_EvalEx, TclEvalEx, TclAdvanceContinuations, TclNREvalObjEx): * generic/tclCmdMZ.c (Tcl_SwitchObjCmd, TclListLines): * generic/tclCompCmds.c (*): * generic/tclCompile.c (TclSetByteCodeFromAny, TclInitCompileEnv) (TclFreeCompileEnv, TclCompileScript, TclCompileTokens): * generic/tclCompile.h (CompileEnv): * generic/tclInt.h (ContLineLoc, Interp): * generic/tclObj.c (ThreadSpecificData, ContLineLocFree) (TclThreadFinalizeObjects, TclInitObjSubsystem, TclContinuationsEnter, (TclContinuationsEnterDerived, TclContinuationsCopy, TclFreeObj) (TclContinuationsGet): * generic/tclParse.c (TclSubstTokens, Tcl_SubstObj): * generic/tclProc.c (TclCreateProc): * generic/tclVar.c (TclPtrSetVar): * tests/info.test (info-30.0-24): Extended the parser, compiler, and execution engine with code and attendant data structures tracking the position of continuation lines which are not visible in the resulting script Tcl_Obj*'s, to properly account for them while counting lines for #280. 2009-08-24 Daniel Steffen * generic/tclInt.h: Annotate Tcl_Panic as noreturn for clang static analyzer in PURIFY builds, replacing preprocessor/assert technique. * macosx/tclMacOSXNotify.c: Fix multiple issues with nested event loops when CoreFoundation notifier is running in embedded mode.

This establishes the assumptions relied on elsewhere that the name stored there is a relative path. Also refactored to make an AppendPath() routine instead of the cut/paste stanzas that were littered throughout. 2009-08-20 Donal K.

Fellows * generic/tclCmdMZ.c (StringIsCmd): Reorganize so that [string is] is more efficient when parsing things that are correct, at a cost of making the empty string test slightly more costly. With this, the cost of doing [string is integer -strict $x] matches [catch {expr {$x+0}}] in the successful case, and greatly outstrips it in the failing case. 2009-07-19 Donal K.

Kenny * generic/tclInt.h (TclNRSwitchObjCmd): * generic/tclBasic.c (builtInCmds): * generic/tclCmdMZ.c (Tcl_SwitchObjCmd): * tests/switch.test (switch-15.1): [Bug 2821401]: Make non-bytecoded [switch] command aware of NRE. 2009-07-13 Andreas Kupries * generic/tclCompile.c (TclInitCompileEnv, EnterCmdWordIndex) (TclCleanupByteCode, TclCompileScript): * generic/tclExecute.c (TclCompileObj, TclExecuteByteCode): * tclCompile.h (ExtCmdLoc): * tclInt.h (ExtIndex, CFWordBC, CmdFrame): * tclBasic.c (DeleteInterpProc, TclArgumentBCEnter) (TclArgumentBCRelease, TclArgumentGet, SAVE_CONTEXT) (RESTORE_CONTEXT, NRCoroutineExitCallback, TclNRCoroutineObjCmd): * generic/tclCmdAH.c (TclNRForObjCmd, TclNRForIterCallback, (ForNextCallback): * generic/tclCmdMZ.c (TclNRWhileObjCmd): Extended the bytecode compiler initialization to recognize the compilation of whole files (NRE enabled 'source' command) and switch to the counting of absolute lines in that case. Further extended the bytecode compiler to track the start line in the generated information, and modified the bytecode execution to recompile an object if the location as per the calling context doesn't match the location saved in the bytecode. This part could be optimized more by using more memory to keep all possibilities which occur around, or by just adjusting the location information instead of a total recompile. Reworked the handling of literal command arguments in bytecode to be saved (compiler) and used (execution) per command (See the TCL_INVOKE_STK* instructions), and not per the whole bytecode. This, and the previous change remove the problems with location data caused by literal sharing (across whole files, but also proc bodies). Simplified the associated datastructures (ExtIndex is gone, as is the function EnterCmdWordIndex). The last change causes the hashtable 'lineLABCPtr' to be state which has to be kept per coroutine, like the CmdFrame stack. Reworked the coroutine support code to create, delete and switch the information as needed. Further reworked the tailcall command as well, it has to pop its own arguments when run in a bytecode context to keep a proper stack in 'lineLABCPtr'. Fixed the mishandling of line information in the NRE-enabled 'for' and 'while' commands introduced when both were made to share their iteration callbacks without taking into account that the loop body is found in different words of the command. Introduced a separate data structure to hold all the callback information, as we went over the limit of 4 direct client-data values for NRE callbacks. The above fixes [Bug 1605269]. 2009-07-12 Donal K.

We only need it there long enough for the right TclInitCompileEnv() call to re-stash it into envPtr->procPtr. Once that is done, the CompileEnv controls. If we let the value of iPtr->compiledProcPtr linger, though, then any other bytecode compile operation that takes place will also have its CompileEnv initialized with it, and that's not correct. The value is meant to control the compile of the proc body only, not other compile tasks that happen along.

Reenabled * tests/nre.test: the failing assertion that was disabled on 2008-12-18: the assertion is correct, the fault was in the management of expansions. * generic/tclExecute.c: Fix both test and code for tailcall * tests/tailcall.test: from within a compiled [eval] body. * tests/tailcall.test: Slightly improved tests 2009-03-20 Don Porter * tests/stringObj.test: [Bug 2597185]: Test stringObj-6.9 checks that Tcl_AppendStringsToObj() no longer crashes when operating on a pure unicode value. * generic/tclExecute.c (INST_CONCAT1): [Bug 2669109]: Panic when appends overflow the max length of a Tcl value. 2009-03-19 Miguel Sofer * generic/tcl.h: * generic/tclInt.h: * generic/tclBasic.c: * generic/tclExecute.c: * generic/tclNamesp.c (Tcl_PopCallFrame): Rewritten tailcall implementation, ::unsupported::atProcExit is (temporarily?) gone.

Use the correct matching allocator. * generic/tclPosixStr.c (Tcl_SignalId,Tcl_SignalMsg): [Patch 1513655]: Added support for SIGINFO, which is present on BSD platforms. 2009-03-14 Donal K. Fellows * unix/tcl.pc.in (new file): [Patch 2243948] (hat0) * unix/configure.in, unix/Makefile.in: Added support for reporting Tcl's public build configuration via the pkg-config system. TEA is still the official mechanism though, in part because pkg-config is not universally supported across all Tcl's supported platforms. 2009-03-11 Miguel Sofer * generic/tclBasic.c (TclNRCoroutineObjCmd): fix Tcl_Obj leak. Diagnosis and fix thanks to GPS. 2009-03-09 Donal K. Fellows * generic/tclCmdMZ.c (Tcl_TryObjCmd, TclNRTryObjCmd): Moved the implementation of [try] from Tcl code into C. Still lacks a bytecode version, but should be better than what was before. 2009-03-04 Donal K. Fellows * generic/tclZlib.c (TclZlibCmd): Checksums are defined to be unsigned 32-bit integers, use Tcl_WideInt to pass to scripts. [Bug 2662434] (ZlibStreamCmd, ChanGetOption): A few other related corrections. 2009-02-27 Jan Nijtmans * generic/tcl.decls: [Bug 218977]: Tcl_DbCkfree needs return value * generic/tclCkalloc.c * generic/tclDecls.h: (regenerated) * generic/tclInt.decls: don't use CONST84/CONST86 here * generic/tclCompile.h: don't use CONST86 here, comment fixing. * generic/tclIO.h: don't use CONST86 here, comment fixing. * generic/tclIntDecls.h (regenerated) 2009-02-25 Don Porter * generic/tclUtil.c (TclStringMatchObj): [Bug 2637173]: Revised the branching on the strObj->typePtr so that untyped values get converted to the "string" type and pass through the Unicode matcher. [Bug 2613766]: Also added checks to only perform "bytearray" optimization on pure bytearray values. * generic/tclCmdMZ.c: Since Tcl_GetCharLength() has its own * generic/tclExecute.c: optimizations for the tclByteArrayType, stop having the callers do them. 2009-02-24 Donal K. Fellows * doc/clock.n, doc/fblocked.n, doc/format.n, doc/lsort.n, * doc/pkgMkIndex.n, doc/regsub.n, doc/scan.n, doc/tclvars.n: General minor documentation improvements. * library/http/http.tcl (geturl, Eof): Added support for 8.6's built in zlib routines. 2009-02-22 Alexandre Ferrieux * tests/lrange.test: Revert commits of 2008-07-23. Those were speed * tests/binary.test: tests, that are inherently brittle. 2009-02-21 Don Porter * generic/tclStringObj.c: Several revisions to the shimmering patterns between Unicode and UTF string reps. Most notably the call: objPtr = Tcl_NewUnicodeObj(...,0); followed by a loop of calls: Tcl_AppendUnicodeToObj(objPtr, u, n); will now grow and append to the Unicode representation. Before this commit, the sequence would convert each append to UTF and perform the append to the UTF rep. This is puzzling and likely a bug. The performance of [string map] is significantly improved by this change (according to the MAP collection of benchmarks in tclbench). Just in case there was some wisdom in the old ways that I missed, I left in the ability to restore the old patterns with a #define COMPAT 1 at the top of the file. 2009-02-20 Don Porter * generic/tclPathObj.c: Fixed mistaken logic in TclFSGetPathType() * tests/fileName.test: that assumed (not "absolute" => "relative"). This is a false assumption on Windows, where "volumerelative" is another possibility. [Bug 2571597] 2009-02-18 Don Porter * generic/tclStringObj.c: Simplify the logic of the Tcl_*SetObjLength() routines. * generic/tclStringObj.c: Rewrite GrowStringBuffer() so that it has parallel structure with GrowUnicodeBuffer(). The revision permits allocation attempts to continue all the way up to failure, with no gap. It also directly manipulates the String and Tcl_Obj internals instead of inefficiently operating via Tcl_*SetObjLength() with all of its extra protections and underdocumented special cases. * generic/tclStringObj.c: Another round of simplification on the allocation macros. 2009-02-17 Jeff Hobbs * win/tcl.m4, win/configure: Check if cl groks _WIN64 already to avoid CC manipulation that can screw up later configure checks. Use 'd'ebug runtime in 64-bit builds. 2009-02-17 Don Porter * generic/tclStringObj.c: Pare back the length of the unicode array in a non-extended String struct to one Tcl_UniChar, meant to hold the terminating NUL character. Non-empty unicode strings are then stored by extending the String struct by stringPtr->maxChars additional slots in that array with sizeof(Tcl_UniChar) bytes per slot. This revision makes the allocation macros much simpler. * generic/tclStringObj.c: Factor out common GrowUnicodeBuffer() and solve overflow and growth algorithm fallbacks in it. * generic/tclStringObj.c: Factor out common GrowStringBuffer(). * generic/tclStringObj.c: Convert Tcl_AppendStringsToObj into * tests/stringObj.test: a radically simpler implementation where we just loop over calls to Tcl_AppendToObj. This fixes [Bug 2597185]. It also creates a *** POTENTIAL INCOMPATIBILITY *** in that T_ASTO can now allocate more space than is strictly required, like all the other Tcl_Append* routines. The incompatibility was detected by test stringObj-6.5, which I've updated to reflect the new behavior. * generic/tclStringObj.c: Revise buffer growth implementation in ExtendStringRepWithUnicode. Use cheap checks to determine that no reallocation is necessary without cost of computing the precise number of bytes needed. Also make use of the string growth algortihm in the case of repeated appends. 2009-02-16 Jan Nijtmans * generic/tclZlib.c: hack needed for official zlib1.dll build. * win/configure.in: fix [Feature Request 2605263] use official * win/Makefile.in: zlib build. * win/configure: (regenerated) * compat/zlib/zdll.lib: new files * compat/zlib/zlib1.dll: * win/Makefile.in: fix [Bug 2605232] tdbc doesn't build when Tcl is compiled with --disable-shared. 2009-02-15 Don Porter * generic/tclStringObj.c: Added protections from invalid memory * generic/tclTestObj.c: accesses when we append (some part of) * tests/stringObj.test: a Tcl_Obj to itself. Added the appendself and appendself2 subcommands to the [teststringobj] testing command and added tests to the test suite. [Bug 2603158] * generic/tclStringObj.c: Factor out duplicate code from Tcl_AppendObjToObj. * generic/tclStringObj.c: Replace the 'size_t uallocated' field of the String struct, storing the number of bytes allocated to store the Tcl_UniChar array, with an 'int maxChars' field, storing the number of Tcl_UniChars that may be stored in the allocated space. This reduces memory requirement a small bit, and makes some range checks simpler to code. * generic/tclTestObj.c: Replace the [teststringobj ualloc] testing * tests/stringObj.test: command with [teststringobj maxchars] and update the tests. * generic/tclStringObj.c: Removed limitation in Tcl_AppendObjToObj where the char length of the result was only computed if the appended string was all single byte characters. This limitation was in place to dodge a bug in Tcl_GetUniChar. With that bug gone, we can take advantage of always recording the length of append results when we know it. 2009-02-14 Don Porter * generic/tclStringObj.c: Revisions so that we avoid creating the strange representation of an empty string with objPtr->bytes == NULL and stringPtr->hasUnicode == 0. Instead in the situations where that was being created, create a traditional two-legged stork representation (objPtr->bytes = tclEmptyStringRep and stringPtr->hasUnicode = 1). In the situations where the strange rep was treated differently, continue to do so by testing stringPtr->numChars == 0 to detect it. These changes make the code more conventional so easier for new maintainers to pick up. Also sets up further simplifications. * generic/tclTestObj.c: Revise updates to [teststringobj] so we don't get blocked by MODULE_SCOPE limits. 2009-02-12 Don Porter * generic/tclStringObj.c: Rewrites of the routines Tcl_GetCharLength, Tcl_GetUniChar, Tcl_GetUnicodeFromObj, Tcl_GetRange, and TclStringObjReverse to use the new macro, and to more simply and clearly split the cases depending on whether a valid unicode rep is present or needs to be created. New utility routine UnicodeLength(), to compute the length of unicode buffer arguments when no length is passed in, with built-in overflow protection included. Update three callers to use it. * generic/tclInt.h: New macro TclNumUtfChars meant to be a faster replacement for a full Tcl_NumUtfChars() call when the string has all single-byte characters. * generic/tclStringObj.c: Simplified Tcl_GetCharLength by * generic/tclTestObj.c: removing code that did nothing. Added early returns from Tcl_*SetObjLength when the desired length is already present; adapted test command to the change. * generic/tclStringObj.c: Re-implemented AppendUtfToUnicodeRep so that we no longer pass through Tcl_DStrings which have their own sets of problems when lengths overflow the int range. Now AUTUR and FillUnicodeRep share a common core routine. 2009-02-12 Donal K. Fellows * generic/tclOODefineCmds.c (TclOOGetDefineCmdContext): Use the correct field in the Interp structure for retrieving the frame to get the context object so that people can extend [oo::define] without deep shenanigans.

Fellows * tests/stringObj.test: [Bug 2006888]: Remove non-ASCII chars from non-comment locations in the file, making it work more reliably in locales with a non-Latin-1 default encoding. * generic/tclNamesp.c (Tcl_FindCommand): [Bug 2519474]: Ensure that the path is not searched when the TCL_NAMESPACE_ONLY flag is given. * generic/tclOODecls.h (Tcl_OOInitStubs): [Bug 2537839]: Make the declaration of this macro work correctly in the non-stub case. 2009-01-29 Don Porter * generic/tclInterp.c: Convert the [interp] command into a * tests/interp.test: [namespace ensemble]. Work in progress * tests/nre.test: to NRE-enable the [interp invokehidden] subcommand. 2009-01-29 Donal K. Fellows * generic/tclNamesp.c (TclMakeEnsemble): [Bug 2529117]: Make this function behave more sensibly when presented with a fully-qualified name, rather than doing strange stuff. 2009-01-28 Donal K. Fellows * generic/tclBasic.c (TclInvokeObjectCommand): Made this understand what to do if it ends up being used on a command with no objProc; that shouldn't happen, but... * generic/tclNamesp.c (TclMakeEnsemble): [Bug 2529157]: Made this understand NRE command implementations better. * generic/tclDictObj.c (DictForCmd): Eliminate unnecessary command implementation. 2009-01-27 Donal K. Fellows * generic/tclOODefineCmds.c (Tcl_ClassSetConstructor): [Bug 2531577]: Ensure that caches of constructor chains are cleared when the constructor is changed. 2009-01-26 Alexandre Ferrieux * generic/tclInt.h: Fix [Bug 1028264]: WSACleanup() too early. * generic/tclEvent.c: The fix introduces "late exit handlers" * win/tclWinSock.c: for similar late process-wide cleanups. 2009-01-26 Alexandre Ferrieux * win/tclWinSock.c: Fix [Bug 2446662]: resync Win behavior on RST with that of unix (EOF). 2009-01-26 Donal K. Fellows * generic/tclZlib.c (ChanClose): Only generate error messages in the interpreter when the thread is not being closed down. [Bug 2536400] 2009-01-23 Donal K. Fellows * doc/zlib.n: Added a note that 'zlib push' is reversed by 'chan pop'. 2009-01-22 Jan Nijtmans * generic/tclCompile.h: CONSTify TclPrintInstruction (TIP #27) * generic/tclCompile.c * generic/tclInt.h: CONSTify TclpNativeJoinPath (TIP #27) * generic/tclFileName.c * generic/tcl.decls: {unix win} is equivalent to {generic} * generic/tclInt.decls * generic/tclDecls.h: (regenerated) * generic/tclIntDecls.h * generic/tclGetDate.y: Single internal const decoration. * generic/tclDate.c: 2009-01-22 Kevin B. Kenny * unix/tcl.m4: Corrected a typo ($(SHLIB_VERSION) should be ${SHLIB_VERSION}). * unix/configure: Autoconf 2.59 2009-01-21 Andreas Kupries * generic/tclIORChan.c (ReflectClose): Fix for [Bug 2458202]. * generic/tclIORTrans.c (ReflectClose): Closing a channel may supply NULL for the 'interp'. Test for finalization needs to be different, and one place has to pull the interp out of the channel instead. 2009-01-21 Don Porter * generic/tclStringObj.c: New fix for [Bug 2494093] replaces the flawed attempt committed 2009-01-09. 2009-01-19 Kevin B. Kenny * unix/Makefile.in: Added a CONFIG_INSTALL_DIR parameter so that * unix/tcl.m4: distributors can control where tclConfig.sh goes. Made the installation of 'ldAix' conditional upon actually being on an AIX system. Allowed for downstream packagers to customize SHLIB_VERSION on BSD-derived systems. Thanks to Stuart Cassoff for [Patch 907924]. * unix/configure: Autoconf 2.59 2009-01-19 David Gravereaux * win/build.vc.bat: Improved tools detection and error message * win/makefile.vc: Reorganized the $(TCLOBJ) file list into seperate parts for easier maintenance. Matched all sources built using -GL to both $(lib) and $(link) to use -LTCG and avoid a warning message. Addressed the over-building nature of the htmlhelp target by moving from a pseudo target to a real target dependent on the entire docs/ directory contents. * win/nmakehlp.c: Removed -g option and GrepForDefine() func as it isn't being used anymore. The -V option method is much better. 2009-01-16 Don Porter * generic/tcl.h: Bump patchlevel to 8.6b1.1 to distinguish * library/init.tcl: CVS snapshots from the 8.6b1 and 8.6b2 releases * unix/configure.in: and to deal with the fact that the 8.6b1 * win/configure.in: version of init.tcl will not [source] in the HEAD version of Tcl. * unix/configure: autoconf-2.59 * win/configure: 2009-01-14 Don Porter * generic/tclBasic.c (Tcl_DeleteCommandFromToken): Reverted most of the substance of my 2009-01-12 commit. NULLing the objProc field of a Command when deleting it is important so that tests for certain classes of commands don't return false positives when applied to deleted command tokens. Overall change is now just replacement of a false comment with a true one. 2009-01-13 Jan Nijtmans * unix/tcl.m4: fix [tcl-Bug 2502365] Building of head on HPUX is broken when using the native CC. * unix/configure (autoconf-2.59) 2009-01-13 Donal K. Fellows * generic/tclCmdMZ.c (Tcl_ThrowObjCmd): Move implementation of [throw] * library/init.tcl (throw): to C from Tcl. 2009-01-12 Don Porter * generic/tclBasic.c (Tcl_DeleteCommandFromToken): One consequence of the NRE rewrite is that there are now situations where a NULL objProc field in a Command struct is perfectly normal. Removed an outdated comment in Tcl_DeleteCommandFromToken that claimed we use cmdPtr->objPtr==NULL as a test of command validity. In fact we use cmdPtr->flags&CMD_IS_DELETED to perform that test. Also removed the setting to NULL, since any extension following the advice of the old comment is going to be broken by NRE anyway, and needs to shift to flag-based testing (or stop intruding into such internal matters). Part of [Bug 2486550]. 2009-01-09 Don Porter * generic/tclStringObj.c (STRING_SIZE): Corrected failure to limit memory allocation requests to the sizes that can be supported by Tcl's memory allocation routines. [Bug 2494093] 2009-01-09 Donal K. Fellows * generic/tclNamesp.c (NamespaceEnsembleCmd): Error out when someone gives wrong # of args to [namespace ensemble create]. [Bug 1558654] 2009-01-08 Don Porter * generic/tclStringObj.c (STRING_UALLOC): Added missing parens required to get correct results out of things like STRING_UALLOC(num + append). [Bug 2494093] 2009-01-08 Donal K. Fellows * generic/tclDictObj.c, generic/tclIndexObj.c, generic/tclListObj.c, * generic/tclObj.c, generic/tclStrToD.c, generic/tclUtil.c, * generic/tclVar.c: Generate errorcodes for the error cases which approximate to "I can't interpret that string as one of those" and "You gave me the wrong number of arguments". 2009-01-07 Donal K. Fellows * doc/dict.n: Added more examples. [Tk Bug 2491235] * tests/oo.test (oo-22.1): Adjusted test to be less dependent on the specifics of how [info frame] reports general frame information, and instead to focus on what methods add to it; that's really what the test is about anyway. 2009-01-06 Don Porter * tests/stringObj.test: Revise tests that demand a NULL Tcl_ObjType in certain values to construct those values with [testdstring] so there's no lack of robustness depending on the shimmer history of shared literals. 2009-01-06 Donal K. Fellows * generic/tclDictObj.c (DictIncrCmd): Corrected twiddling in internals of dictionaries so that literals can't get destroyed. * tests/expr.test: Eliminate non-ASCII char. [Bug 2006879] * generic/tclOOInfo.c (InfoObjectMethodsCmd,InfoClassMethodsCmd): Only delete pointers that were actually allocated! [Bug 2489836] * generic/tclOO.c (TclNRNewObjectInstance, Tcl_NewObjectInstance): Perform search for existing commands in right context. [Bug 2481109] 2009-01-05 Donal K. Fellows * generic/tclCmdMZ.c (TclNRSourceObjCmd): Make implementation of the * generic/tclIOUtil.c (TclNREvalFile): [source] command be NRE enabled so that [yield] inside a script sourced in a coroutine can work. [Bug 2412068] 2009-01-04 Donal K. Fellows * generic/tclCmdAH.c: Tidy up spacing and code style. 2009-01-03 Kevin B. Kenny * library/clock.tcl (tcl::clock::add): Fixed error message formatting in the case where [clock add] is presented with a bad switch. * tests/clock.test (clock-65.1) Added a test case for the above problem [Bug 2481670]. 2009-01-02 Donal K. Fellows * unix/tcl.m4 (SC_CONFIG_CFLAGS): Force the use of the compatibility version of mkstemp() on IRIX. [Bug 878333] * unix/configure.in, unix/Makefile.in (mkstemp.o): * compat/mkstemp.c (new file): Added a compatibility implementation of the mkstemp() function, which is apparently needed on some platforms.
