+A NOTE ON THE CHANGELOG:
+Starting in early 2011, Tcl source code has been under the management of
+fossil, hosted at http://core.tcl.tk/tcl/ .  Fossil presents a "Timeline"
+view of changes made that is superior in every way to a hand edited log file.
+Because of this, many Tcl developers are now out of the habit of maintaining
+this log file.  You may still find useful things in it, but the Timeline is
+a better first place to look now.
+============================================================================
 
-	* generic/tclStringObj.c (Tcl_(Attempt)SetObjLength):	Added
-	protections against callers asking for negative lengths.  It is
-	likely when this happens that an integer overflow is to blame.
-	[Bug 2553906].

+	Corrected implementation of the core of uuencode handling so that the
+	line length processing is correctly applied.
+	***POTENTIAL INCOMPATIBILITY***
+	Existing code that was using the old versions and working around the
+	limitations will now need to do far less. The -maxlen option now has
+	strict limits on the range of supported lengths; this is a limitation
+	of the format itself.

-	* 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.
+	* unix/tcl.m4: Eliminate NO_VIZ macro as current zlib uses HAVE_HIDDEN
+	instead. One more last-moment fix for FreeBSD by Pietro Cerutti

-	* 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

+	* generic/tclExecute.c: fix for perf bug detected by Kieran
+	(https://groups.google.com/forum/?fromgroups#!topic/comp.lang.tcl/vfpI3bc-DkQ),
+	diagnosed by dgp to be a close relative of [Bug 781585], which was

+	* generic/tclCompCmds.c (TclCompileBreakCmd, TclCompileContinueCmd):
+	Added code to allow [break] and [continue] to be issued as a jump (in
+	the most common cases) rather than using the more expensive exception
+	processing path in the bytecode engine. [Bug 3614226]: Partial fix for
+	the issues relating to cleaning up the stack when dealing with [break]
+	and [continue].
 
-	* 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.

+	[lsearch -nocase] and [lsort -nocase].
 
-	* 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).

+	* generic/tclParse.c:	whether or not the parsed list element was
+	* generic/tclUtil.c:	enclosed in braces.  In practice, no callers
+	really care about that.  What the callers really want to know is
+	whether the list element value exists as a literal substring of the
+	string being parsed, or whether a call to TclCopyAndCollpase() is
+	needed to produce the list element value.  Now the final argument is
+	changed to do what callers actually need. This is a better fit for the
+	calls in tclParse.c, where now a good deal of post-processing checking
+	for "naked backslashes" is no longer necessary.
+	***POTENTIAL INCOMPATIBILITY***
+	For any callers calling in via the internal stubs table who really do
+	use the final argument explicitly to check for the enclosing brace
+	scenario.  Simply looking for the braces where they must be is the

+
+	[dogeen-assembler-branch]
+
+	* tests/assemble.test: Added more "white box" tests.
+	* generic/tclAssembly.c: Added the error checking and reporting
+	for undefined labels. Revised code so that no pointers into the
+	bytecode sequence are held (because the sequence can move!),
+	that no Tcl_HashEntry pointers are held (because the hash table
+	doesn't guarantee their stability!) and to eliminate the BBHash
+	table, which is merely additional information indexed by jump
+	labels and can just as easily be held in the 'label' structure.
+	Renamed shared structures to CamelCase, and renamed 'label' to
+	JumpLabel because other types of labels may eventually be possible.

+
+	* generic/tclIORTrans.c (ForwardProc): [Bug 2964425]: When cleaning
+	the stables, it is sometimes necessary to do more than the minimum. In
+	this case, rationalizing the variables for a forwarded limit? method
+	required removing an extra Tcl_DecrRefCount too.
+
+	* generic/tclOO.h, generic/tclOOInt.h: [Patch 2961556]: Change TclOO
+	to use the same style of function typedefs as Tcl, as this is about
+	the last chance to get this right.
+
+	***POTENTIAL INCOMPATIBILITY***
+	Source code that uses function typedefs from TclOO will need to update
+	variables and argument definitions so that pointers to the function
+	values are used instead. Binary compatibility is not affected.
+
+	* generic/*.c, generic/tclInt.h, unix/*.c, macosx/*.c: Applied results
+	of doing a Code Audit. 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  <dkf@users.sf.net>
+
+	* 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.

+	* generic/tclIndexObj.c: fix [AT 86258]: special-casing of empty

+2010-02-27  Donal K. Fellows  <dkf@users.sf.net>
+
+	* 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  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c:   Split this file into two pieces to make it

+
+2010-02-26  Reinhard Max  <max@suse.de>

+	* 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  <dkf@users.sf.net>
+
+	* 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  <patthoyts@users.sourceforge.net>
+
+	* tests/zlib.test: Add tests for [Bug 2818131] which was crashing with

+
+2010-02-25  Jan Nijtmans  <nijtmans@users.sf.net>

+
+	* 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  <andreask@activestate.com>
+
+	* 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  <nijtmans@users.sf.net>
+
+	* unix/tclUnixPort.h:   Remove unnecessary EXTERN's, which already are

+2010-02-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileStringLenCmd): Make [string length]

+
+2010-02-19  Stuart Cassoff  <stwo@users.sourceforge.net>
+
+	* tcl.m4: Correct compiler/linker flags for threaded builds on

+	* configure: (regenerated).
+
+2010-02-19  Donal K. Fellows  <dkf@users.sf.net>
+
+	* 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  <dkf@users.sf.net>
+
+	* 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  <nijtmans@users.sf.net>
+
+	* generic/tclInt.h: Change order of various struct members,
+	fixing potential binary incompatibility with Tcl 8.5
+
+2010-02-16  Donal K. Fellows  <dkf@users.sf.net>
+
+	* 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  <nijtmans@users.sf.net>
+
+	* tools/genStubs.tcl:   Reverted earlier rename from tcl*Stubs to

+2010-02-15  Donal K. Fellows  <dkf@users.sf.net>
+
+	* 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  <dkf@users.sf.net>
+
+	* 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  <nijtmans@users.sf.net>
+
+	* win/tcl.m4:		Use -pipe for gcc on win32
+	* win/configure:	(mingw/cygwin) (regenerated)

+
+2010-02-11  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* tests/list.test: Add tests for explicit \0 in a string argument to
+	the list command.
+
+2010-02-11  Donal K. Fellows  <dkf@users.sf.net>
+
+	* 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  <mdejong@users.sourceforge.net>
+
+	[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  <dkf@users.sf.net>
+
+	* 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  <dkf@users.sf.net>
+
+	* 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  <ferrieux@users.sourceforge.net>
+
+	* tools/genStubs.tcl: Remove dependency on 8.5+ idiom "in" in
+	expressions.
+
+2010-02-08  Donal K. Fellows  <dkf@users.sf.net>
+
+	* 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  <dkf@users.sf.net>
+
+	* 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  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileErrorCmd): Added compilation of the
+	[error] command. No new bytecodes.
+
+2010-02-05  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* 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/tcl*Decls.h (regenerated)

+
+	* 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  <nijtmans@users.sf.net>
+
+	* 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/tclOOMethod.c:pointer, and other formatting
+	* generic/tcl*Decls.h:	(regenerated)

+				uninitialized in this function
+
+2010-02-04  Donal K. Fellows  <dkf@users.sf.net>
+
+	* 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  <dkf@users.sf.net>
+
+	* generic/tclVar.c (ArrayUnsetCmd): More corrections.
+
+2010-02-02  Donal K. Fellows  <dkf@users.sf.net>
+
+	* 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  <dkf@users.sf.net>
+
+	* 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  <dkf@users.sf.net>
+
+	* 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

+
+	* generic/tclVar.c (TclPtrUnsetVar): Var reference version of the code
+	to unset a variable. Required for INST_UNSET bytecodes.
+
+2010-01-29  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* 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/tclOOBasic.c (TclOO_Object_Destroy): Move the execution of

+	* generic/tclOO.c (AllocObject, MyDeletedTrace, ObjectRenamedTrace):
+	(ObjectNamespaceDeleted): Stop various ways of getting at commands

+
+	* win/tclAppInit.c (Tcl_AppInit): [Bug 2902965]: Reverted Jan's change
+	that added a call to Tcl_InitStubs. The 'tclsh' and 'tcltest' programs

+	with the Stubs library, but only with the main Tcl library. (In any

+
+	* 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.

+
+	* library/safe.tcl: A series of patches which bring the SafeBase up to

+	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.

+2009-11-01  Joe Mistachkin  <joe@mistachkin.com>
+
+	* 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.

+
+2009-10-29  Don Porter  <dgp@users.sourceforge.net>
+
+	* 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.

+	* generic/tclLiteral.c:	[Bug 2888044]: Fixed 2 bugs.

+	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.

-	* library/tm.tcl (::tcl::tm::UnknownHandler): Changed 'source' to
-	'source -encoding utf-8'. This fixes a portability problem of Tcl

+
+	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].

+
+	* 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.

+
+	* generic/tclStringObj.c:	Rewrite GrowStringBuffer() so that it

+	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.

+2009-02-17  Don Porter  <dgp@users.sourceforge.net>
+
+	* 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.

+2009-02-14  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c:	Revisions so that we avoid creating
+	the strange representation of an empty string with

+	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

+	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

+2009-02-01  David Gravereaux  <davygrvy@pobox.com>

+2009-01-28  Donal K. Fellows  <dkf@users.sf.net>

+
+2009-01-21  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c: New fix for [Bug 2494093] replaces the
+	flawed attempt committed 2009-01-09.
+
+2009-01-19  Kevin B. Kenny  <kennykb@acm.org>
+
+	* unix/Makefile.in: [Patch 907924]:Added a CONFIG_INSTALL_DIR
+	* unix/tcl.m4:      parameter so that 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

+	Cassoff for his help.
+	* unix/configure: Autoconf 2.59
+
+2009-01-19  David Gravereaux  <davygrvy@pobox.com>
+
+	* 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  <dgp@users.sourceforge.net>
+
+	* 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:
 
+2009-01-14  Don Porter  <dgp@users.sourceforge.net>
+
+	* 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  <nijtmans@users.sf.net>
+
+	* unix/tcl.m4: [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  <dkf@users.sf.net>
+
+	* generic/tclCmdMZ.c (Tcl_ThrowObjCmd):	Move implementation of [throw]
+	* library/init.tcl (throw):		to C from Tcl.
+
+2009-01-12  Don Porter  <dgp@users.sourceforge.net>
+
+	* 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  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c (STRING_SIZE): [Bug 2494093]: Corrected
+	failure to limit memory allocation requests to the sizes that can be
+	supported by Tcl's memory allocation routines.
+
+2009-01-09  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclNamesp.c (NamespaceEnsembleCmd): [Bug 1558654]: Error out
+	when someone gives wrong # of args to [namespace ensemble create].
+
+2009-01-08  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c (STRING_UALLOC): [Bug 2494093]: Added missing
+	parens required to get correct results out of things like
+	STRING_UALLOC(num + append).
+
+2009-01-08  Donal K. Fellows  <dkf@users.sf.net>
+
+	* 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  <dkf@users.sf.net>
+
+	* doc/dict.n: [Tk Bug 2491235]: Added more examples.
+
+	* 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  <dgp@users.sourceforge.net>
+
+	* 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  <dkf@users.sf.net>
+
+	* generic/tclDictObj.c (DictIncrCmd): Corrected twiddling in internals
+	of dictionaries so that literals can't get destroyed.
+
+	* tests/expr.test: [Bug 2006879]: Eliminate non-ASCII char.
+
+	* generic/tclOOInfo.c (InfoObjectMethodsCmd,InfoClassMethodsCmd):
+	[Bug 2489836]: Only delete pointers that were actually allocated!
+
+	* generic/tclOO.c (TclNRNewObjectInstance, Tcl_NewObjectInstance):
+	[Bug 2481109]: Perform search for existing commands in right context.
+
+2009-01-05  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCmdMZ.c (TclNRSourceObjCmd): [Bug 2412068]: Make
+	* generic/tclIOUtil.c (TclNREvalFile):    implementation of the
+	[source] command be NRE enabled so that [yield] inside a script
+	sourced in a coroutine can work.
+
+2009-01-04  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCmdAH.c: Tidy up spacing and code style.
+
+2009-01-03  Kevin B. Kenny  <kennykb@acm.org>
+
+	* 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  <dkf@users.sf.net>
+
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS): [Bug 878333]: Force the use of the
+	compatibility version of mkstemp() on IRIX.
+	* unix/configure.in, unix/Makefile.in (mkstemp.o):
+	* compat/mkstemp.c (new file): [Bug 741967]: Added a compatibility
+	implementation of the mkstemp() function, which is apparently needed
+	on some platforms.

+
+	*** 8.6a2 TAGGED FOR RELEASE ***
+
+	* changes:	Updates for 8.6a2 release.
+

+	support for code written for 8.5 headers.
+
+	* generic/tclUtil.c (TclReToGlob):	Added missing set of the

+
+2008-08-21  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tcl.h:	Reduced the use of CONST86 and eliminated
+	* generic/tcl.decls:	the use of CONST86_RETURN to support source
+	code compatibility with Tcl 8.5 on those public routines passing
+	(Tcl_Filesystem *), (Tcl_Timer *), and (Tcl_Objtype *) values which

+2008-08-11  Andreas Kupries  <andreask@activestate.com>
+
+	* library/tm.tcl: Added a 'package provide' command to the generated
+	ifneeded scripts of Tcl Modules, for early detection of conflicts
+	between the version specified through the file name and a 'provide'
+	command in the module implementation, if any. Note that this change
+	also now allows Tcl Modules to not provide a 'provide' command at all,
+	and declaring their version only through their filename.
+
+	* generic/tclProc.c (Tcl_ProcObjCmd): Fixed memory leak triggered by

+	* generic/tclExecute.c: Fix for [Bug 2038069] by dgp.
+	* tests/execute.test:
+
+2008-08-04  Miguel Sofer  <msofer@users.sf.net>
+
+	* tests/nre.test: Added tests for [if], [while] and [for]. A test
+	for [foreach] has been added and marked as knownbug, awaiting for it
+	to be NR-enabled.
+
+	* generic/tclBasic.c:	   Made atProcExit commands run

+2008-08-04  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c: Stopped faulty double-logging of errors to

+	[Bug 2037338]
+
+2008-08-03  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c:	   New unsupported command atProcExit that
+	* generic/tclCompile.h:	   shares the implementation with tailcall.
+	* generic/tclExecute.c:	   Fixed a segfault in tailcalls. Tests added.
+	* generic/tclInt.h:
+	* generic/tclInterp.c:
+	* generic/tclNamesp.c:
+	* tests/unsupported.test:
+
+2008-08-02  Miguel Sofer  <msofer@users.sf.net>
+
+	* tests/NRE.test (removed):	Migrated tests to standard locations,
+	* tests/nre.test (new):		separating core functionality from the
+	* tests/unsupported.test (new):	experimental commands.
+
+2008-08-01  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* doc/Exit.3:			Do not call Tcl_Finalize implicitly
+	* generic/tclEvent.c:		on DLL_PROCESS_DETACH as it may lead
+	* win/tclWin32Dll.c (DllMain):	to issues and the user should be
+	explicitly calling Tcl_Finalize before unloading regardless. Clarify
+	the docs to note the explicit need in embedded use.
+
+2008-08-01  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Revised timing of the CmdFrame stack
+	* tests/info.test:	management in TclEvalEx so that the CmdFrame
+	will still be on the stack at the time Tcl_LogCommandInfo is called to
+	append another level of -errorinfo information. Sets the stage to add
+	file and line data to the stack trace. Added test to check that [info
+	frame] functioning remains unchanged by the revision.
+
+2008-07-31  Miguel Sofer  <msofer@users.sf.net>
+
+	* tests/NRE.test:  Replaced all deep-recursing tests by shallower
+	tests that actually measure the C-stack depth. This makes them
+	bearable again (even under memdebug) and avoid crashing on failure.
+
+	* generic/tclBasic.c:	NR-enabling [catch], [if] and [for] and
+	* generic/tclCmdAH.c:	[while] (the script, not the tests)
+	* generic/tclCmdIL.c:
+	* generic/tclCmdMZ.c:
+	* generic/tclInt.h:
+	* tests/NRE.test:
+
+	* generic/tclBasic.c:	Moved the few remaining defs from tclNRE.h to

+
+2008-07-29  Miguel Sofer  <msofer@users.sf.net>
+
+	* tests/NRE.test: New tests that went MIA in the NRE revamping
+
+	* generic/tclBasic.c:	Clean up
+	* generic/tclNRE.h:
+	* generic/tclExecute.c:
+
+	* generic/tclBasic.c:	Made use of the thread's alloc cache stored in
+	* generic/tclInt.h:	the ekeko at interp creation to avoid hitting
+	* generic/tclNRE.h:	the TSD each time an NRE callback is pushed or
+	* generic/tclThreadAlloc.c: pulled; the approach is suitably general
+	to extend to every other obj allocation where an interp is know; this
+	is left for some other time, requires a lot of grunt work.
+
+	* generic/tclExecute.c:	 Fix [Bug 2030670] that cause TclStackRealloc
+	to panic on rare corner cases. Thx ajpasadyn for diagnose and patch.
+
+	* generic/tcl.decls:	 Completely revamped NRE implementation, with
+	* generic/tclBasic.c:	 (almost) unchanged API.
+	* generic/tclCompile.h:
+	* generic/tclExecute.c:	 TEBC will require a bit of a facelift, but
+	* generic/tclInt.decls:	 TEOV at least looks great now. There are new
+	* generic/tclInt.h:	 tests (incomplete!) to verify that execution
+	* generic/tclInterp.c:	 is indeed in the same TEBC instance, at the
+	* generic/tclNRE.h:	 same level in all stacks involved. Tailcalls
+	* generic/tclNamesp.c:	 are still a bit leaky, still deserving to be
+	* generic/tclOOBasic.c:	 in tcl::unsupported.
+	* generic/tclOOMethod.c:
+	* generic/tclProc.c:	 Uninit'd var warnings in TEBC with -O2, no
+	* generic/tclTest.c:	 warnings otherwise.
+
+2008-07-28  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* doc/FileSystem.3:		CONSTified many functions using
+	* generic/tcl.decls:		Tcl_FileSystem which all are supposed
+	* generic/tclDecls.h:		to be a constant, but this was not
+	* generic/tclFileSystem.h:	reflected in the API: Tcl_FSData,
+	* generic/tclIOUtil.c:		Tcl_FSGetInternalRep, Tcl_FSRegister,
+	* generic/tclPathObj.c:		Tcl_FSNewNativePath, Tcl_FSUnregister,
+	* generic/tclTest.c:		Tcl_FSGetFileSystemForPath ...
+	This change complies with TIP #27.
+	***POTENTIAL INCOMPATIBILITY***
+
+2008-07-28  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclBasic.c: Added missing ref count when creating an empty
+	string as path (TclEvalEx). In 8.4 the missing code caused panics in
+	the testsuite. It doesn't in 8.5. I am guessing that the code path
+	with the missing the incr-refcount is not invoked any longer. Because
+	the bug in itself is certainly the same.
+
+2008-07-27  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclOOMethod.c (PushMethodCallFrame): Remove hack that should
+	have gone when this code was merged into Tcl.
+
+2008-07-27  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* doc/Object.3:		CONSTified 3 functions using Tcl_ObjType
+	* doc/ObjectType.3:	which all are supposed to be a constant, but
+	* generic/tcl.decls:	this was not reflected in the API:
+	* generic/tcl.h:	Tcl_RegisterObjType, Tcl_ConvertToType,
+	* generic/tclDecls.h:	Tcl_GetObjType
+	* generic/tclObj.c:	Introduced a CONST86_RETURN, so extensions
+	* generic/tclCompCmds.c: which use Tcl_ObjType directly can be
+	* generic/tclOOMethod.c: modified to compile against both Tcl 8.5 and
+	* generic/tclTestobj.c:	Tcl 8.6. tclDecls.h regenerated
+	This change complies with TIP #27.
+	***POTENTIAL INCOMPATIBILITY***
+
+2008-07-25  Andreas Kupries  <andreask@activestate.com>
+
+	* test/info.test: More work on singleTestInterp usability. [1605269]
+
+	* tests/info.test: Tests 38.* added, exactly testing the tracking of
+	location for uplevel scripts. Resolved merge conflict on info-37.0,
+	switched !singleTestInterp constraint to glob matching instead. Ditto
+	info-22.8, removed constraint, more glob matching, and reduced the
+	depth of the stack we check. More is coming, right now I want to
+	commit the bug fixes.
+
+	* tests/oo.test: Updated oo-22.1 for expanded location tracking.
+
+	* generic/tclCompile.c (TclInitCompileEnv): Reorganized the
+	initialization of the #280 location information to match the flow in
+	TclEvalObjEx to get more absolute contexts.
+
+	* generic/tclBasic.c (TclEvalObjEx): Added missing cleanup of extended
+	location information.
+
+2008-07-25  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tests/info.test (info-37.0): Add !singleTestInterp constraint;
+	(info-22.8, info-23.0): switch to glob matching to avoid sensitivity
+	to tcltest.tcl line number changes, remove knownBug constraint, fix
+	expected result. [Bug 1605269]
+
+2008-07-24  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* doc/Notifier.3:      CONSTified 4 functions in the Notifier which
+	* doc/Thread.3:	       all have a Tcl_Time* in it which is supposed
+	* generic/tcl.decls:   to be a constant, but this was not reflected
+	* generic/tcl.h:       reflected in the API:
+	* generic/tclDecls.h:	    Tcl_SetTimer, Tcl_WaitForEvent,
+	* generic/tclNotify.c:	    Tcl_ConditionWait, Tcl_SetMaxBlockTime
+	* macosx/tclMacOSXNotify.c:
+	* generic/tclThread.c: Introduced a CONST86, so extensions which have
+	* unix/tclUnixNotfy.c: have their own Notifier (are there any?) can
+	* unix/tclUnixThrd.c:  can be modified to compile against both Tcl
+	* win/tclWinNotify.c:  Tcl 8.5 and Tcl 8.6
+	* win/tclWinThrd.c:    Regenerated tclDecls.h with "make stubs".
+	This change complies with TIP #27
+	***POTENTIAL INCOMPATIBILITY***
+
+2008-07-23  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>
+
+	* tests/lrange.test: Added relative speed test to check for lrange
+	in-place optimization committed 2008-06-30.
+	* tests/binary.test: Added relative speed test to check for pure byte
+	array CONCAT1 optimization committed 2008-06-30.
+
+2008-07-23  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/info.test: Reordered the tests to have monotonously increasing
+	numbers.
+
+	* generic/tclBasic.c: Modified TclArgumentGet to reject pure lists
+	* generic/tclCmdIL.c: immediately, without search. Reworked setup of
+	* generic/tclCompile.c: eoFramePtr, doesn't need the line information,
+	* tests/info.test: more sensible to have everything on line 1 when
+	eval'ing a pure list. Updated the users of the line information to
+	special case this based on the frame type (i.e.
+	TCL_LOCATION_EVAL_LIST). Added a testcase demonstrating the new
+	behaviour.
+
+2008-07-23  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c (GetCommandSource): Added comment with
+	explanation and warning for waintainers.
+
+2008-07-22  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclCompile.c: Made the new TclEnterCmdWordIndex static, and
+	* generic/tclCompile.h: ansified.
+
+	* generic/tclBasic.c: Ansified the new functions. Added missing
+	function comments.
+
+	* generic/tclBasic.c: Reworked the handling of bytecode literals for
+	* generic/tclCompile.c: #280 to fix the abysmal performance for deep
+	* generic/tclCompile.h: recursion, replaced the linear search through
+	* generic/tclExecute.c: the whole stack with another hashtable and
+	* generic/tclInt.h: simplified the data structure used by the compiler
+	by using an array instead of a hashtable. Incidentially this also
+	fixes the memory leak reported via [Bug 2024937].
+
+2008-07-22  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c:	 Added numLevels field to CommandFrame, let
+	* generic/tclExecute.c:	 GetCommandSource use it. This solves [Bug
+	* generic/tclInt.h:	 2017146]. Thx dgp for the analysis.
+
+2008-07-21  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclBasic.c: Extended the existing TIP #280 system (info
+	* generic/tclCmdAH.c: frame), added the ability to track the absolute
+	* generic/tclCompCmds.c: location of literal procedure arguments, and
+	* generic/tclCompile.c: making this information available to uplevel
+	* generic/tclCompile.h: eval, and siblings. This allows proper
+	* generic/tclInterp.c: tracking of absolute location through custom
+	* generic/tclInt.h: (Tcl-coded) control structures based on uplevel,
+	* generic/tclNamesp.c: etc.

+
+	* generic/tcl.decls:	  Changed the implementation of

+	* generic/tclDecls.h:	  Tcl_NRObjProc, replaced with
+	* generic/tclExecute.c:	  Tcl_NRCmdSwap (proposed public

+
+2008-07-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclDictObj.c (SetDictFromAny): Make the list->dict
+	transformation a bit more efficient; modern dicts are ordered and so
+	we can round-trip through lists without needing the string rep at all.
+	* generic/tclListObj.c (SetListFromAny): Make the dict->list
+	transformation not lossy of internal representations and hence more
+	efficient. [Bug 2008248] (ajpasadyn) but using a more efficient patch.
+
+	* tests/fileName.test: Revise to reduce the obscurity of tests. In
+	particular, all tests should now produce informative messages on
+	failure and the quantity of [catch]-based obscurity is now greatly
+	reduced; non-erroring is now checked for directly.
+
+2008-07-19  Donal K. Fellows  <dkf@users.sf.net>
+
+	* tests/env.test: Add LANG to the list of variables that are not
+	touched by the environment variable tests, so that subprocesses can
+	get their system encoding correct.
+
+	* tests/exec.test, tests/env.test: Rewrite so that non-ASCII
+	characters are not used in the final comparison. Part of fixing [Bug
+	1513659].
+

+	methods and forwards are). On the other hand, callers of
+	TclOOInvokeObject (which is only in the internal stub table) will need

+
+2008-07-03  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/package.tcl:	Removed [file readable] testing from
+	[tclPkgUnknown] and friends. We find out soon enough whether a file is
+	readable when we try to [source] it, and not testing before allows us
+	to workaround the bugs on some common filesystems where [file

+2008-07-01  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/regc_nfa.c (duptraverse): Impose a maximum stack depth on
+	the single most recursive part of the RE engine. The actual maximum
+	may need tuning, but that needs a system with a small stack to carry
+	out. [Bug 1905562]
+
+	* tests/string.test: Eliminate non-ASCII characters from the actual
+	test script. [Bug 2006884]
+
+2008-06-30  Donal K. Fellows  <dkf@users.sf.net>

+
+2008-06-24  Pat Thoyts  <patthoyts@users.sourceforge.net>

+
+2008-06-23  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclPathObj.c: Fixed bug in Tcl_GetTranslatedPath() when
+	operating on the "Special path" variant of the "path" Tcl_ObjType
+	intrep. A full normalization was getting done, in particular, coercing
+	relative paths to absolute, contrary to what the function of producing

+2008-06-19  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclOO.c (Tcl_ObjectContextInvokeNext): Corrected 'next' (at

+

+
+	* doc/tm.n: Followup to changelog entry 2008-03-18 regarding

+	observable in the [clock] command itself.
+
+2008-06-16  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclCmdIL.c (TclInfoFrame): Moved the code looking up the
+	* tests/info.test: information for key 'proc' out of the
+	TCL_LOCATION_BC branch to after the switch, this is common to all
+	frame types. Updated the testsuite to match. This was exposed by the
+	2008-06-08 commit (Miguel), switching uplevel from direct eval to
+	compilation. [Bug 1987851]
+
+2008-06-16  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/ioTrans.test (iortrans-11.*): Fixed same issue as for

+	entry on 2008-06-10 by myself.
+
+2008-06-13  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/rules.vc: SYMBOLS macro is now being set to zero when $(OPTS) is

+
+2008-06-13  Joe Mistachkin  <joe@mistachkin.com>
+
+	TIP #285 IMPLEMENTATION
+
+	* doc/Eval.3: Added documentation for the Tcl_CancelEval and
+	Tcl_Canceled functions and the TCL_CANCEL_UNWIND flag bit.
+	* doc/after.n: Corrected the spelling of 'canceled' in the
+	documentation.
+	* doc/interp.n: Added documentation for [interp cancel].
+	* generic/tcl.decls: Added the Tcl_CancelEval and Tcl_Canceled
+	functions to the stubs table.
+	* generic/tcl.h: Added the TCL_CANCEL_UNWIND flag bit.
+	* generic/tclBasic.c: The bulk of the script cancellation
+	functionality is defined here. Added code to initialize and manage the
+	script cancellation hash table in a thread-safe manner. Reset script
+	cancellation flags prior to increasing the nesting level (if the
+	nesting level is currently zero) and always cooperatively check for
+	script cancellation near the start of TclEvalObjvInternal and after
+	invoking async handlers.
+	* generic/tclDecls.h: Regenerated.
+	* generic/tclEvent.c: Call TclFinalizeEvaluation during finalization
+	to cleanup the script cancellation hash table. During [vwait], always
+	cooperatively check for script cancellation. Corrected the spelling of
+	'canceled' in comments to be consistent with the documentation.
+	* generic/tclExecute.c: Reset script cancellation flags prior to
+	increasing the nesting level (if the nesting level is currently zero)
+	and always cooperatively check for script cancellation after invoking
+	async handlers. Prevent [catch] from catching script cancellation when
+	the TCL_CANCEL_UNWIND flag is set (similar to the manner used by TIP
+	143 when a limit has been exceeded).
+	* generic/tclInt.decls: Added TclResetCancellation to the internal
+	stubs table.
+	* generic/tclInt.h: Added asyncCancel and asyncCancelMsg fields to the
+	private Interp structure. Added private interp flag value CANCELED to
+	help control script cancellation.
+	* generic/tclIntDecls.h: Regenerated.
+	* generic/tclInterp.c (Tcl_InterpObjCmd): Added [interp cancel]
+	subcommand.
+	* generic/tclNotify.c (Tcl_DeleteEventSource): Corrected the spelling
+	of 'canceled' in comments to be consistent with the documentation.
+	* generic/tclParse.c: Reset script cancellation flags prior to
+	* generic/tclProc.c: increasing the nesting level (if the nesting
+	level is currently zero) and cooperatively check for script
+	cancellation prior to evaluating commands.
+	* generic/tclStubInit.c: Regenerated.
+	* generic/tclThreadTest.c (Tcl_ThreadObjCmd): Added script
+	cancellation support ([testthread cancel]).
+	Modified [testthread id] to allow querying of the 'main' thread ID.
+	Corrected comments to reflect the actual command syntax. Made
+	[testthread wait] cooperatively check for script cancellation. Added
+	[testthread event] to allow for processing one pending event without
+	blocking.
+	* generic/tclTimer.c: Delay for a maximum of 500 milliseconds prior to
+	checking for async handlers and script cancellation.
+	* tests/cmdAH.test: Changed [interp c] to [interp create].
+	* tests/interp.test: Added and fixed tests for [interp cancel].
+	* tests/thread.test: Added tests for script cancellation via
+	[testthread cancel].
+	* tools/man2help2.tcl: Fixed problems with WinHelp target (see
+	* tools/man2tcl.c: [Bug 1934200], [Bug 1934265], and [Bug 1934272]).
+	* win/makefile.vc: Added 'pdbs' option for Windows build rules to
+	* win/rules.vc:	   allow for non-debug builds with full symbols.
+	* win/tcl.hpj.in: Corrected version for WinHelp target.
+	* win/tclWinNotify.c: Used SleepEx and WaitForSingleObjectEx on
+	* win/tclWinThrd.c: Windows because they are alertable.
+
+2008-06-12  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/Makefile.in:		Add complete deps on tclDTrace.h.

+	* unix/configure.in (SunOS):	Fix static DTrace-enabled build.
+
+	* unix/tcl.m4 (SunOS-5.11): Fix 64bit amd64 support with gcc & Sun cc.
+	* unix/configure: autoconf-2.59
+
+	* macosx/Tcl.xcodeproj/project.pbxproj:	Add tclIORTrans.c; updates and
+						cleanup for Xcode 3.1/Leopard.
+	* macosx/Tcl.xcode/project.pbxproj:	Sync Tcl.xcodeproj changes.
+	* macosx/README:			Document new build configs.
+
+2008-06-10  Joe English  <jenglish@users.sourceforge.net>
+
+	* generic/tclEncoding.c(UtfToUtfProc): Avoid unwanted sign extension
+	when converting incomplete UTF-8 sequences. See [Bug 1908443] for
+	details.
+
+2008-06-10  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/ioTrans.test (iortrans.tf-6.1): Fixed the [Bug 1988552],
+	reported by Kevin. Have to close the channel before removal of the
+	file. Fixed same bug in test 'iortrans.tf-11.0', after fixing missing
+	cleanup of the file in 'iortrans.tf-11.*'. Lastly fixed the names of
+	the threaded tests 'iortrans-8.*' to the correct 'iortrans.tf-8.*'.
+
+2008-06-09  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* generic/tclIORTrans.c (ReflectInput): Fixed a bug triggered by Pat
+	Thoyts <patthoyts@users.sourceforge.net>. Reset the EOF flag after
+	draining the Tcl level into the result buffer, to make sure that the
+	result buffer will be drained as well by repeated calls to
+	ReflectInput should it contain more than one buffer-full of data.
+	Without that reset the higher I/O system will not call on ReflectInput
+	anymore due to the assumed EOF, thus losing the data which did not fit
+	in the buffer of the call which caused the eof and drain.
+
+2008-06-09  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclOOCall.c (TclOOGetSortedMethodList): Plug memory leak
+	that occurred when all methods were hidden. [Bug 1987817]
+
+2008-06-08  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c:	   Compilation of uplevel scripts, allow

+	* win/Makefile.in:  Integration of new files into build rules.
+	* win/makefile.vc:  Integration of new files into build rules.
+
+	NOTE: The file 'tclIORTrans.c' has a lot of code in common with the
+	      file 'tclIORChan.c', as that made it much easier to develop the
+	      reference implementation as a separate module. Now that the
+	      transforms have been committed the one thing left to do is to go

+
+2008-06-01  Joe Mistachkin  <joe@mistachkin.com>
+

+
+2008-06-01  Kevin B. Kenny  <kennykb@acm.org>

+
+	* generic/tclDictObj.c:	 Added missing initializers to the ensemble
+				 map to silence a compiler warning. Thanks to
+				 George Peter Staplin for the report.
+
+	* generic/tclOOMethod.c: Fix a bug where the refcount of a method was

+2008-05-15  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* win/makefile.vc: We should use the thread allocator for threaded
+	* win/rules.vc:	   builds. Added 'tclalloc' option to disable.
+
+2008-05-09  George Peter Staplin  <georgeps@xmission.com>
+
+	* tools/tsdPerf.c:	A loadable Tcl extension for testing TSD
+	performance.
+	* tools/tsdPerf.tcl:	A simplistic tool that uses the thread
+	extension and tsdPerf.so to get some performance metrics by,
+	simulating, simple TSD contention.
+
+2008-05-09  George Peter Staplin  <georgeps@xmission.com>
+
+	* generic/tcl.h:	Make Tcl_ThreadDataKey a void *.
+	* generic/tclInt.h:	Change around some function names and add some
+	new per-platform declarations for thread-specific data functions.
+	* generic/tclThread.c:	Make use of of the new function names that no
+	longer have a Tclp prefix.
+	* generic/tclThreadStorage.c: Replace the core thread-specific data
+	(TSD) mechanism with an array offset solution that eliminates the hash
+	tables, and only uses one slot of native TSD. Many thanks to Kevin B.
+	Kenny for his help with this.
+
+	* unix/tclUnixThrd.c:	Add platform-specific TSD functions for use by
+	* win/tclWinThrd.c:	tclThreadStorage.c.
+
+2008-05-09  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tests/dict.test (dict-19.2): Corrected a bug where the test was
+	changed to use [apply] instead of a temporary proc, but the cleanup
+	script still attempted to delete the temporary proc.
+
+2008-05-07  Donal K. Fellows  <dkf@cspool38.cs.man.ac.uk>
+
+	* generic/tclCompCmds.c (TclCompileDictAppendCmd): Fix silly off-by
+	one error that caused a crash every time a compiled 'dict append' with
+	more than one argument was used. Found by Colin McCormack.
+
+2008-05-02  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* generic/tclBasic.c:	 Converted the [binary] command into an
+	* generic/tclBinary.c:	 ensemble.
+	* generic/tclInt.h:
+	* test/binary.test:	 Updated the error tests for ensemble errors.
+
+	* generic/tclFileName.c: Reverted accidental commit of TIP 316 APIs.
+
+2008-04-27  Donal K. Fellows  <dkf@users.sf.net>
+
+	* */*.c: A large tranche of getting rid of pre-C89-isms; if your
+	compiler doesn't support things like proper function declarations,
+	'void' and 'const', borrow a proper one when building Tcl. (The header
+	files allow building things that link against Tcl with really ancient
+	compilers still; the requirement is just when building Tcl itself.)
+
+2008-04-26  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>
+
+	* generic/tclAsync.c: Tcl_AsyncDelete(): panic if attempt to locate
+	handler token fails. Happens when some other thread attempts to delete
+	somebody else's token.
+
+	Also, panic early if we find out the wrong thread attempting to delete
+	the async handler (common trap). As, only the one that created the
+	handler is allowed to delete it.
+
+2008-04-24  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/ioCmd.test: Extended testsuite for reflected channel
+	implementation. Added test cases about how it handles if the rug is
+	pulled out from under a channel (= killing threads, interpreters
+	containing the tcl command for a channel, and channel sitting in a
+	different interpreter/thread.)
+
+	* generic/tclIORChan.c: Fixed the bugs exposed by the new testcases,
+	redone most of the cleanup and exit handling.
+
+2008-04-21  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclIOUtil.c:		Removed all code delimited by
+	* generic/tclTest.c:		USE_OBSOLETE_FS_HOOKS, completing
+	* tests/ioCmd.test:		the deprecation path for these
+	* tests/ioUtil.test (removed):	obsolete interfaces. (Code was active
+	in Tcl 8.4, present but enabled only by customized compile switch in
+	Tcl 8.5, and now completely gone for Tcl 8.6). Also removed all tests
+	relevant only to the removed interfaces.
+
+2008-04-19  George Peter Staplin  <georgeps@xmission.com>
+
+	* doc/Ensemble.3: Fix a typo: s/defiend/defined/
+	Thanks to hat0 for spotting this.
+
+2008-04-16  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclInt.h:		Make stubs tables 'static const' and
+	* generic/tclStubInit.c:	export only module-scope pointers to
+	* generic/tclStubLib.c:		the main stubs tables (for package
+	* tools/genStubs.tcl:		initialization). [Patch 1938497]
+	* generic/tclBasic.c (Tcl_CreateInterp):
+	* generic/tclTomMathInterface.c (TclTommath_Init):
+
+	* generic/tclInt.h:		Revise Tcl_SetNotifier() to use a
+	* generic/tclNotify.c:		module-scope hooks table instead of
+	* generic/tclStubInit.c:	runtime stubs-table modification;
+	* macosx/tclMacOSXNotify.c:	ensure all hookable notifier functions
+	* win/tclWinNotify.c:		check for hooks; remove hook checks in
+	* unix/tclUnixNotfy.c:		notifier API callers. [Patch 1938497]
+
+2008-04-15  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (CopyData):	Applied another patch by Alexandre
+	* io.test (io-53.8a):		Ferrieux <ferrieux@users.sf.net>,
+	* chanio.test (chan-io-53.8a):	to shift EOF handling to the async
+	part of the command if a callback is specified, should the channel be
+	at EOF already when fcopy is called. Testcase by myself.
+
+2008-04-15  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/Makefile.in:	Adjust tclDTrace.h dependencies for removal
+				of tclStubLib.o from TCL_OBJS. [Bug 1942795]
+
+2008-04-14  Kevin B. Kenny  <kennykb@acm.org>
+
+	* unix/tclUnixTime.c (NativeGetTime): Removed obsolete use of
+	'struct timezone' in the call to 'gettimeofday'. [Bug 1942197]
+
+	* tests/clock.test (clock-33.5, clock-33.5a, clock-33.8, clock-33.8a):
+	Added comments to the test that it can fail on a heavily loaded
+	system.
+
+2008-04-10  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Keeping check for negative
+	values, changed to not be an error, but behave like the special value
+	-1 (copy all, default).
+
+	* tests/iocmd.test (iocmd-15.{12,13}): Removed.
+
+	* tests/io.test (io-52.5{,a,b}): Reverted last change, added
+	* tests/chanio.test (chan-io-52.5{,a,b}): comment regarding the
+	meaning of -1, added two more testcases for other negative values,
+	and input wrapped to negative.
+
+2008-04-09  Donal K. Fellows  <dkf@users.sf.net>
+
+	* tests/{fCmd,unixFCmd,winFCmd,winFile}.test: Tidying up of the test
+	suite to make better use of tcltest2 and be clearer about what is
+	being tested.
+
+	* win/Makefile.in (html): Added target for doing convenient
+	documentation builds, mirroring the one from unix/Makefile.
+
+2008-04-09  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/chanio.test (chan-io-52.5): Removed '-size -1' from test,
+	* tests/io.test (io-52.5): does not seem to have any bearing, and was
+	an illegal value. Test case is not affected by the value of -size,
+	test flag restoration and that evrything was properly copied.
+
+	* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Added checking of -size value
+	* tests/ioCmd.test (iocmd-15.{13,14}): to reject negative values, and
+	values overflowing 32-bit signed. Basic patch by Alexandre Ferrieux
+	<ferrieux@users.sourceforge.net>, with modifications from me to
+	separate overflow from true negative value. Extended testsuite. [Bug
+	1557855]
+
+2008-04-09  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tests/chanio.test (chan-io-53.8,53.9,53.10): Fix typo & quoting for
+	* tests/io.test (io-53.8,53.9,53.10):	       spaces in builddir path
+
+2008-04-08  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c: Added comments to the alignment macros used in
+	GrowEvaluationStack() and friends.
+
+2008-04-08  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tools/genStubs.tcl:	Revert erroneous 2008-04-02 change marking
+				*StubsPtr as EXTERN instead of extern.
+
+	* generic/tclDecls.h:	make genstubs
+	* generic/tclIntDecls.h:
+	* generic/tclIntPlatDecls.h:
+	* generic/tclPlatDecls.h:
+	* generic/tclTomMathDecls.h:
+
+2008-04-07  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/io.test (io-53.10): Testcase for bi-directional fcopy.
+	* tests/chanio.test:
+	* generic/tclIO.c: Additional changes to data structures for fcopy and
+	* generic/tclIO.h: channels to perform proper cleanup in case of a
+	channel having two background copy operations running as is now
+	possible.
+
+	* generic/tclIO.c (BUSY_STATE, CheckChannelErrors, TclCopyChannel):
+	New macro, and the places using it. This change allows for
+	bi-directional fcopy on channels. Thanks to Alexandre Ferrieux
+	<ferrieux@users.sourceforge.net> for the patch. [Bug 1350564]
+
+2008-04-07  Reinhard Max  <max@suse.de>
+
+	* generic/tclStringObj.c (Tcl_AppendFormatToObj): Fix [format {% d}]
+	so that it behaves the same way as in 8.4 and as C's printf().
+	* tests/format.test: Add a test for '% d' and '%+d'.
+
+2008-04-05  Kevin B. Kenny  <kennykb@acm.org>
+
+	* win/tclWinFile.c: (WinSymLinkDirectory): Fixed a problem that Tcl
+	was creating an NTFS junction point (IO_REPARSE_TAG_MOUNT_POINT) but
+	filling in the union member for a Vista symbolic link. We had gotten
+	away with this error because the union member
+	(SymbolicLinkReparseBuffer) was misdefined in this file and in the
+	'winnt.h' in early versions of MinGW. MinGW 3.4.2 has the correct
+	definition of SymbolicLinkReparseBuffer, exposing the mismatch, and
+	making tests cmdAH-19.4.1, fCmd-28.*, and filename-11.* fail.
+	* tests/chanio.test (chan-io-53.9):
+	* tests/io.test (io-53.9): Made test cleanup robust against the
+	possibility of slow process shutdown on Windows.
+
+	* win/tcl.m4: Added -D_CRT_SECURE_NO_DEPRECATE and
+	-DCRT_NONSTDC_NO_DEPRECATE to the MSVC compilation flags so that the
+	compilation doesn't barf on perfectly reasonable Posix system calls.
+	* win/configure: Manually patched (don't have the right autoconf to
+	hand).
+
+2008-04-04  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/io.test (io-53.9): Added testcase for [Bug 780533], based
+	* tests/chanio.test: on Alexandre's test script. Also fixed problem
+	with timer in preceding test, was not canceled properly in the ok case
+
+2008-04-04  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIORChan.c (ReflectOutput): Allow zero return from write
+	when input was zero-length anyway. Otherwise keept it an error, and
+	separate the message from 'written too much'.
+
+	* tests/ioCmd.test (iocmd-24.6): Testcase updated for changed message.
+
+	* generic/tclIORChan.c (ReflectClose): Added missing removal of the
+	now closed channel from the reflection map. Before we could crash the
+	system by invoking 'chan postevent' on a closed reflected channel,
+	dereferencing the dangling pointer in the map.
+
+	* tests/ioCmd.test (iocmd-31.8): Testcase for the above.
+
+2008-04-03  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (CopyData): Applied patch [Bug 1932639] to
+	* tests/io.test: prevent fcopy from calling -command synchronously
+	* tests/chanio.test: the first time. Thanks to Alexandre Ferrieux
+	<ferrieux@users.sourceforge.net> for report and patch.
+
+2008-04-02  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tcl.decls:	Remove 'export' declarations of symbols now
+				only in libtclstub and no longer in libtcl.
+
+	* generic/tclStubLib.c:	Make symbols in libtclstub.a MODULE_SCOPE to
+	* tools/genStubs.tcl:	avoid exporting them from libraries that link
+				with -ltclstub; constify tcl*StubsPtr and stub
+				table hook pointers. [Bug 1819422]

+
+2008-04-02  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (CopyData): Applied patch for fcopy problem [Bug
+	780533], with many thanks to Alexandre Ferrieux
+	<ferrieux@users.sourceforge.net> for tracking it down and providing a
+	solution. Still have to convert his test script into a proper test
+	case.
+
+2008-04-01  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclStrToD.c: Applied patch for [Bug 1839067] (fp rounding
+	* unix/tcl.m4:	       setup on solaris x86, native cc), provided by
+			       Michael Schlenker.
+
+2008-04-01  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStubLib.c:	Removed needless #ifdef complexity.
+
+	* generic/tclStubLib.c (Tcl_InitStubs):	Added missing error message.

+	* unix/Makefile.in:	in libtcl.so, but is present only in
+	* win/Makefile.in:	libtclstub.a. This tightens up the rules for

+
+2008-03-30  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclInt.h (TclIsNaN):
+	* unix/configure.in: Added code to the configurator to check for a
+			     standard isnan() macro and use it if one is
+			     found. This change avoids bugs where the test of
+			     ((d) != (d)) is optimized away by an
+			     overaggressive compiler. [Bug 1783544]
+	* generic/tclObj.c: Added missing #include <math.h> needed to locate
+			    isnan() after the above change.
+
+	* unix/configure: autoconf-2.61
+
+	* tests/mathop.test (mathop-25.9, mathop-25.14): Modified tests to
+	deal with (slightly buggy) math libraries in which pow() returns an
+	incorrectly rounded result. [Bug 1808174]
+
+2008-03-26  Don Porter  <dgp@users.sourceforge.net>
+
+	*** 8.5.2 TAGGED FOR RELEASE ***
+

+
+2008-03-28  Donal K. Fellows  <dkf@users.sf.net>
+
+	* tests/fCmd.test: Substantial rewrite to use many more tcltest

+2008-03-24  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* generic/tclBinary.c: [Bug 1923966] - crash in binary format
+	* tests/binary.test:   Added tests for the above crash condition.
+
+2008-03-21  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/switch.n: Clarified documentation in respect of two-argument
+	invokation. [Bug 1899962]
+

+	the [switch] command. [Bug 1854435]
+
+2008-03-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tcl.h, generic/tclThreadAlloc.c: Tidied up the declarations
+	of Tcl_GetMemoryInfo so that it is always defined. Will panic when
+	called against a Tcl that was previously built without it at all,
+	which is OK because that also indicates a serious mismatch between
+	memory configuration options.
+
+2008-03-19  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tcl.h, generic/tclThreadAlloc.c (Tcl_GetMemoryInfo): Make
+	sure this function is available when direct linking. [Bug 1868171]
+
+	* tests/reg.test (reg-33.14): Marked nonPortable because some
+	environments have small default stack sizes. [Bug 1905562]
+
+2008-03-18  Andreas Kupries  <andreask@activestate.com>
+
+	* 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.
+
+	***INCOMPATIBILITY*** for all Tcl Modules already written in non-utf-8
+	compatible encodings.
+
+2008-03-18  Don Porter  <dgp@users.sourceforge.net>

+	alignment of memory allocated by GrowEvaluationStack(). [Bug 1914503]
+
+2008-03-18  Andreas Kupries  <andreask@activestate.com>
+
+	* library/tm.tcl (::tcl::tm::Defaults): Modified handling of
+	environment variables. Solution slightly different than proposed in
+	the report. Using the underscored form TCLX_y_TM_PATH even if
+	TCLX.y_TM_PATH exists. Also using a loop to cut prevent code
+	replication. [Bug 1914604]
+
+2008-03-16  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileDictForCmd): Correct the handling
+	of stack space calculation (the jump pattern used was confusing the
+	simple-minded code doing the calculations). [Bug 1903325]
+
+	* doc/lreplace.n: Clarified documentation of what happens with
+	negative indices. [Bug 1905809] Added example, tidied up formatting.
+
+2008-03-14  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c (OldMathFuncProc):	Same workaround protection
+	from bad TclStackAlloc() alignment. Thanks George Peter Staplin.
+
+	* generic/tclCmdIL.c (Tcl_LsortObjCmd):	Use ckalloc() to allocate
+	SortElement arrays instead of TclStackAlloc() which isn't getting
+	alignment right. Workaround for [Bug 1914503].
+
+2008-03-14  Reinhard Max  <max@suse.de>

+	[Bug 1893053]
+
+	* macosx/tclMacOSXNotify.c: Avoid using CoreFoundation after fork() on

+
+	* macosx/Tcl.xcodeproj/project.pbxproj:	Add support for Xcode 3.1 and
+	* macosx/Tcl.xcodeproj/default.pbxuser:	configs for building with

+
+2008-03-11  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclVar.c (TclDeleteNamespaceVars):
+	* tests/var.test (var-8.2): Unset traces on vars should be called with
+	a FQ named during namespace deletion. This was causing infinite loops
+	when unset traces recreated the var, as reported by Julian Noble. [Bug
+	1911919]
+
+2008-03-10  Don Porter  <dgp@users.sourceforge.net>
+
+	* changes:		Updated for 8.5.2 release.
+
+	* doc/http.n:	Revised to indicate that [package require http 2.5.5]
+	is needed to get all the documented commands ([http::meta]).
+
+	* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd):	Added error
+	* tests/event.test (event-5.*):	checking to protect against callers
+	passing invalid return options dictionaries. [Bug 1901113]
+
+	* generic/tclBasic.c (ExprAbsFunc):	Revised so that the abs()
+	* tests/expr.test:	function and the [::tcl::mathfunc::abs]
+	command do not return the value of -0, or equivalent values with more
+	alarming string reps like -1e-350. [Bug 1893815]
+
+2008-03-07  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclResult.c (ReleaseKeys): Workaround for [Bug 1904907].
+	Reset the return option keys to NULL to allow full re-initialization
+	by GetKeys(). This introduces a memory leak for the key objects, but
+	gets us around a crash in the finalization of reflected channels when
+	handling returns, either at compile- or runtime. In both cases we
+	access the keys after they have been released by their thread exit
+	handler. A proper fix is entangled with the untangling of the
+	finalization ordering and attendant issues. For now we choose the
+	lesser evil.
+
+2008-03-07  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c (Tcl_ExprObj):	Revised expression bytecode
+	compiling so that bytecodes invalid due to changing context or due to
+	the difference between expressions and scripts are not reused. [Bug
+	1899164]
+
+	* generic/tclCmdAH.c:	Revised direct evaluation implementation of
+	[expr] so that [expr $e] caches compiled bytecodes for the expression
+	as the intrep of $e.
+
+	* tests/execute.test (execute-6.*):	More tests checking that
+	script bytecode is invalidated in the right situations.
+
+2008-03-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* win/configure.in: Add AC_HEADER_STDC to support msys/win64.
+
+2008-03-06  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/namespace.n: Minor tidying up. [Bug 1909019]
+
+2008-03-04  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/execute.test (6.3,4):	Added tests for [Bug 1899164].
+
+2008-03-03  Reinhard Max  <max@suse.de>
+
+	* unix/tclUnixChan.c: Fix mark and space parity on Linux, which uses
+	CMSPAR instead of PAREXT.
+
+2008-03-02  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclNamesp.c (GetNamespaceFromObj):
+	* tests/interp.test (interp-28.2): Spoil the intrep of an nsNameType
+	obj when the reference crosses interpreter boundaries.
+
+2008-02-29  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclResult.c (Tcl_SetReturnOptions):	Revised the refcount
+	management of Tcl_SetReturnOptions to become that of a conventional
+	Consumer routine. Thanks to Peter Spjuth for pointing out the
+	difficulties calling Tcl_SetReturnOptions with non-0-count value for
+	options.
+	* generic/tclExecute.c (INST_RETURN_STK): Revised the one caller
+	within Tcl itself which passes a non-0-count value to
+	Tcl_SetReturnOptions().
+
+	* generic/tclBasic.c (Tcl_AppendObjToErrorInfo):	Revised the
+	refcount management of Tcl_AppendObjToErrorInfo to become that of a
+	conventional Consumer routine. This preserves the ease of use for the
+	overwhelming common callers who pass in a 0-count value, but makes the
+	proper call with a non-0-count value less surprising.
+	* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd):	Revised the
+	one caller within Tcl itself which passes a non-0-count value to
+	Tcl_AppendObjToErrorInfo().
+
+2008-02-28  Joe English  <jenglish@users.sourceforge.net>
+
+	* unix/tclPort.h, unix/tclCompat.h, unix/tclUnixChan.h: Reduce scope

+	Don't let the second pass lose commandPtr value allocated during the
+	first pass.
+
+	* generic/tclCompExpr.c (ParseExpr):	Plug memory leak in error
+	message generation.
+
+	* generic/tclStringObj.c (Tcl_AppendFormatToObj): [format %llx $big]

+
+	* generic/tclCompCmds.c (TclCompileReturnCmd):	The 2007-10-18 commit
+	to optimize compiled [return -level 0 $x] [RFE 1794073] introduced a
+	memory leak of the return options dictionary. Fixing that.
+
+2008-02-27  Pat Thoyts  <patthoyts@users.sourceforge.net>

+	clock value is in the range of a 64-bit integer. [Bug 1862555]
+	* library/clock.tcl (::tcl::clock::format, ::tcl::clock::scan,
+	(::tcl::clock::add, ::tcl::clock::LocalizeFormat): Fixed bugs in

+	* tests/clock.test (clock-61.*, clock-62.1): Regression tests for [Bug
+	1862555] and [Bug 1902423].
+
+2008-02-26  Joe English  <jenglish@users.sourceforge.net>
+
+	* generic/tclIOUtil.c, unix/tclUnixPort.h, unix/tclUnixChan.c:

 34. Is there a Java version of zlib?
 
     Probably what you want is to use zlib in Java. zlib is already included
     as part of the Java SDK in the java.util.zip package. If you really want
     a version of zlib written in the Java language, look on the zlib home

 35. I get this or that compiler or source-code scanner warning when I crank it
     up to maximally-pedantic. Can't you guys write proper code?
 
     Many years ago, we gave up attempting to avoid warnings on every compiler

-    were downright silly. So now, we simply make sure that the code always

 36. Valgrind (or some similar memory access checker) says that deflate is
     performing a conditional jump that depends on an uninitialized value.
     Isn't that a bug?
 
-    No.  That is intentional for performance reasons, and the output of
-    deflate is not affected.  This only started showing up recently since
-    zlib 1.2.x uses malloc() by default for allocations, whereas earlier
-    versions used calloc(), which zeros out the allocated memory.

 38. How can I encrypt/decrypt zip files with zlib?
 
-    zlib doesn't support encryption. The original PKZIP encryption is very weak
-    and can be broken with freely available programs. To get strong encryption,
-    use GnuPG, http://www.gnupg.org/ , which already includes zlib compression.

 40. Does zlib support the new "Deflate64" format introduced by PKWare?
 
-    No. PKWare has apparently decided to keep that format proprietary, since
-    they have not documented it as they have previous compression formats.

+
+    There are no zip functions in zlib.  You are probably using minizip by

+    part of zlib.  In fact none of the stuff in contrib is part of zlib.  The

-program's bottleneck seems to be mostly L1-cache contention, for which
-there is no real way to work around without rewriting the basic
-algorithm. The speedup on average is around 5-10% (which is generally
-less than the amount of variance between subsequent executions).
-However, when used at level 9 compression, the cache contention can
-drop enough for the assembly version to achieve 10-20% speedup (and
-sometimes more, depending on the amount of overall redundancy in the
-files). Even here, though, cache contention can still be the limiting
-factor, depending on the nature of the program using the zlib library.
-This may also mean that better improvements will be seen on a Pentium
-with MMX, which suffers much less from L1-cache contention, but I have
-not yet verified this.
-
-Note that this code has been tailored for the Pentium in particular,
-and will not perform well on the Pentium Pro (due to the use of a
-partial register in the inner loop).
-
-If you are using an assembler other than GNU as, you will have to
-translate match.S to use your assembler's syntax. (Have fun.)

- * Two optimization notes on the choice of instructions:

- * The first instruction uses a 16-bit address, which costs an extra,

- * zeroing the high word, due to the 3-cycle misalignment penalty which
- * would occur half the time. This also turns out to be cheaper than
- * doing two separate 8-bit accesses, as the memory is so rarely in the
- * L1 cache.
- *
- * The window buffer, however, apparently spends a lot of time in the
- * cache, and so it is faster to retrieve the word at the end of the
- * match string with two 8-bit loads. The instructions that test the
- * word at the beginning of the match string, however, are executed
- * much less frequently, and there it was cheaper to use 16-bit
- * instructions, which avoided the necessity of saving off and
- * subsequently reloading one of the other registers.

+I've been ignoring these assembly routines for years, believing that
+gcc's generated code had caught up with it sometime around gcc 2.95
+and the major rearchitecting of the Pentium 4. However, I recently

-;
-; this file contain two implementation of longest_match
-;
-;  longest_match_7fff : written 1996 by Gilles Vollant optimized for 
-;            first Pentium. Assume s->w_mask == 0x7fff
-;  longest_match_686 : written by Brian raiter (1998), optimized for Pentium Pro
-;
-;  for using an seembly version of longest_match, you need define ASMV in project
-;  There is two way in using gvmat32.asm
-;
-;  A) Suggested method
-;    if you want include both longest_match_7fff and longest_match_686
-;    compile the asm file running
-;           ml /coff /Zi /Flgvmat32.lst /c gvmat32.asm
-;    and include gvmat32c.c in your project
-;    if you have an old cpu (386,486 or first Pentium) and s->w_mask==0x7fff,
-;        longest_match_7fff will be used
-;    if you have a more modern CPU (Pentium Pro, II and higher)
-;        longest_match_686 will be used
-;    on old cpu with s->w_mask!=0x7fff, longest_match_686 will be used,
-;        but this is not a sitation you'll find often
-;
-;  B) Alternative
-;    if you are not interresed in old cpu performance and want the smaller
-;       binaries possible
-;
-;    compile the asm file running
-;           ml /coff /Zi /c /Flgvmat32.lst /DNOOLDPENTIUMCODE gvmat32.asm
-;    and do not include gvmat32c.c in your project (ou define also 
-;              NOOLDPENTIUMCODE)
-;
-; note : as I known, longest_match_686 is very faster than longest_match_7fff
-;        on pentium Pro/II/III, faster (but less) in P4, but it seem
-;        longest_match_7fff can be faster (very very litte) on AMD Athlon64/K8

+MiniZip - Copyright (c) 1998-2010 - by Gilles Vollant - version 1.1 64 bits from Mathias Svensson
+
+Introduction
+---------------------
+MiniZip 1.1 is built from MiniZip 1.0 by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
+
+When adding ZIP64 support into minizip it would result into risk of breaking compatibility with minizip 1.0.
+All possible work was done for compatibility.
+
+
+Background
+---------------------
+When adding ZIP64 support Mathias Svensson found that Even Rouault have added ZIP64 
+support for unzip.c into minizip for a open source project called gdal ( http://www.gdal.org/ )
+
+That was used as a starting point. And after that ZIP64 support was added to zip.c
+some refactoring and code cleanup was also done.
+
+
+Changed from MiniZip 1.0 to MiniZip 1.1
+---------------------------------------
+* Added ZIP64 support for unzip ( by Even Rouault )
+* Added ZIP64 support for zip ( by Mathias Svensson )
+* Reverted some changed that Even Rouault did.
+* Bunch of patches received from Gulles Vollant that he received for MiniZip from various users.
+* Added unzip patch for BZIP Compression method (patch create by Daniel Borca)
+* Added BZIP Compress method for zip
+* Did some refactoring and code cleanup
+
+
+Credits
+
+ Gilles Vollant    - Original MiniZip author
+ Even Rouault      - ZIP64 unzip Support
+ Daniel Borca      - BZip Compression method support in unzip
+ Mathias Svensson  - ZIP64 zip support
+ Mathias Svensson  - BZip Compression method support in zip
+
+ Resources
+
+ ZipLayout   http://result42.com/projects/ZipFileLayout
+             Command line tool for Windows that shows the layout and information of the headers in a zip archive.
+             Used when debugging and validating the creation of zip files using MiniZip64
+
+
+ ZIP App Note  http://www.pkware.com/documents/casestudies/APPNOTE.TXT
+               Zip File specification
+
+
+Notes.
+ * To be able to use BZip compression method in zip64.c or unzip64.c the BZIP2 lib is needed and HAVE_BZIP2 need to be defined.

+
+         For more info read MiniZip_info.txt
+
+         Changes
+
+    Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
+    Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
+               More if/def section may be needed to support other platforms
+    Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
+                          (but you should use iowin32.c for windows instead)

+.SH NAME
+miniunzip - uncompress and examine ZIP archives
+.SH SYNOPSIS
+.B miniunzip
+.RI [ -exvlo ]
+zipfile [ files_to_extract ] [-d tempdir]
+.SH DESCRIPTION
+.B minizip
+is a simple tool which allows the extraction of compressed file
+archives in the ZIP format used by the MS-DOS utility PKZIP.  It was
+written as a demonstration of the
+.IR zlib (3)
+library and therefore lack many of the features of the
+.IR unzip (1)
+program.
+.SH OPTIONS
+A number of options are supported.  With the exception of
+.BI \-d\  tempdir
+these must be supplied before any
+other arguments and are:
+.TP
+.BI \-l\ ,\ \-\-v
+List the files in the archive without extracting them.
+.TP
+.B \-o
+Overwrite files without prompting for confirmation.
+.TP
+.B \-x
+Extract files (default).
+.PP
+The
+.I zipfile
+argument is the name of the archive to process. The next argument can be used
+to specify a single file to extract from the archive.
+
+Lastly, the following option can be specified at the end of the command-line:
+.TP
+.BI \-d\  tempdir
+Extract the archive in the directory
+.I tempdir
+rather than the current directory.
+.SH SEE ALSO
+.BR minizip (1),
+.BR zlib (3),
+.BR unzip (1).
+.SH AUTHOR
+This program was written by Gilles Vollant.  This manual page was
+written by Mark Brown <broonie@sirena.org.uk>. The -d tempdir option
+was added by Dirk Eddelbuettel <edd@debian.org>.

+.RI [ -o ]
+zipfile [ " files" ... ]
+.SH DESCRIPTION
+.B minizip
+is a simple tool which allows the creation of compressed file archives
+in the ZIP format used by the MS-DOS utility PKZIP.  It was written as
+a demonstration of the
+.IR zlib (3)
+library and therefore lack many of the features of the
+.IR zip (1)
+program.
+.SH OPTIONS
+The first argument supplied is the name of the ZIP archive to create or
+.RI -o
+in which case it is ignored and the second argument treated as the
+name of the ZIP file.  If the ZIP file already exists it will be
+overwritten.
+.PP
+Subsequent arguments specify a list of files to place in the ZIP
+archive.  If none are specified then an empty archive will be created.

+  Oct-2009 - Mathias Svensson - Fixed problem if uncompressed size was > 4G and compressed size was <4G
+                                should only read the compressed/uncompressed size from the Zip64 format if
+                                the size from normal header was 0xFFFFFFFF
+  Oct-2009 - Mathias Svensson - Applied some bug fixes from paches recived from Gilles Vollant

+                                Patch created by Daniel Borca
+
+  Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

+   data can be produced or consumed, even for an arbitrarily long
+   sequentially presented input data stream, using only an a priori
+   bounded amount of intermediate storage.  The format presently uses
+   the DEFLATE compression method but can be easily extended to use
+   other compression methods.  It can be implemented readily in a manner
+   not covered by patents.  This specification also defines the ADLER-32
+   checksum (an extension and improvement of the Fletcher checksum),
+   used for detection of data corruption, and provides an algorithm for
+   computing it.

+1. Introduction
+
+   1.1. Purpose
+
+      The purpose of this specification is to define a lossless
+      compressed data format that:
+
+          * Is independent of CPU type, operating system, file system,
+            and character set, and hence can be used for interchange;
+
+          * Can be produced or consumed, even for an arbitrarily long
+            sequentially presented input data stream, using only an a
+            priori bounded amount of intermediate storage, and hence can
+            be used in data communications or similar structures such as
+            Unix filters;
+
+          * Can use a number of different compression methods;
+
+          * Can be implemented readily in a manner not covered by
+            patents, and hence can be practiced freely.
+
+      The data format defined by this specification does not attempt to
+      allow random access to compressed data.

+RFC 1950       ZLIB Compressed Data Format Specification        May 1996
+
+
+   1.2. Intended audience
+
+      This specification is intended for use by implementors of software
+      to compress data into zlib format and/or decompress data from zlib
+      format.
+
+      The text of the specification assumes a basic background in
+      programming at the level of bits and other primitive data
+      representations.
+
+   1.3. Scope
+
+      The specification specifies a compressed data format that can be
+      used for in-memory compression of a sequence of arbitrary bytes.
+
+   1.4. Compliance
+
+      Unless otherwise indicated below, a compliant decompressor must be
+      able to accept and decompress any data set that conforms to all
+      the specifications presented here; a compliant compressor must
+      produce data sets that conform to all the specifications presented
+      here.
+
+   1.5.  Definitions of terms and conventions used
+
+      byte: 8 bits stored or transmitted as a unit (same as an octet).
+      (For this specification, a byte is exactly 8 bits, even on
+      machines which store a character on a number of bits different
+      from 8.) See below, for the numbering of bits within a byte.
+
+   1.6. Changes from previous versions
+
+      Version 3.1 was the first public release of this specification.
+      In version 3.2, some terminology was changed and the Adler-32
+      sample code was rewritten for clarity.  In version 3.3, the
+      support for a preset dictionary was introduced, and the
+      specification was converted to RFC style.
+
+2. Detailed specification
+
+   2.1. Overall conventions
+
+      In the diagrams below, a box like this:
+
+         +---+
+         |   | <-- the vertical bars might be missing
+         +---+

+
+RFC 1950       ZLIB Compressed Data Format Specification        May 1996
+
+
+      represents one byte; a box like this:
+
+         +==============+
+         |              |
+         +==============+
+
+      represents a variable number of bytes.
+
+      Bytes stored within a computer do not have a "bit order", since
+      they are always treated as a unit.  However, a byte considered as
+      an integer between 0 and 255 does have a most- and least-
+      significant bit, and since we write numbers with the most-
+      significant digit on the left, we also write bytes with the most-
+      significant bit on the left.  In the diagrams below, we number the
+      bits of a byte so that bit 0 is the least-significant bit, i.e.,
+      the bits are numbered:
+
+         +--------+
+         |76543210|
+         +--------+
+
+      Within a computer, a number may occupy multiple bytes.  All
+      multi-byte numbers in the format described here are stored with
+      the MOST-significant byte first (at the lower memory address).
+      For example, the decimal number 520 is stored as:
+
+             0     1
+         +--------+--------+
+         |00000010|00001000|
+         +--------+--------+
+          ^        ^
+          |        |
+          |        + less significant byte = 8
+          + more significant byte = 2 x 256
+
+   2.2. Data format
+
+      A zlib stream has the following structure:
+
+           0   1
+         +---+---+
+         |CMF|FLG|   (more-->)

+
+      Any data which may appear after ADLER32 are not part of the zlib
+      stream.
+
+      CMF (Compression Method and flags)
+         This byte is divided into a 4-bit compression method and a 4-
+         bit information field depending on the compression method.
+
+            bits 0 to 3  CM     Compression method
+            bits 4 to 7  CINFO  Compression info
+
+      CM (Compression method)
+         This identifies the compression method used in the file. CM = 8
+         denotes the "deflate" compression method with a window size up
+         to 32K.  This is the method used by gzip and PNG (see
+         references [1] and [2] in Chapter 3, below, for the reference
+         documents).  CM = 15 is reserved.  It might be used in a future
+         version of this specification to indicate the presence of an
+         extra field before the compressed data.
+
+      CINFO (Compression info)
+         For CM = 8, CINFO is the base-2 logarithm of the LZ77 window
+         size, minus eight (CINFO=7 indicates a 32K window size). Values
+         of CINFO above 7 are not allowed in this version of the
+         specification.  CINFO is not defined in this specification for
+         CM not equal to 8.
+
+      FLG (FLaGs)
+         This flag byte is divided as follows:
+
+            bits 0 to 4  FCHECK  (check bits for CMF and FLG)
+            bit  5       FDICT   (preset dictionary)
+            bits 6 to 7  FLEVEL  (compression level)
+
+         The FCHECK value must be such that CMF and FLG, when viewed as
+         a 16-bit unsigned integer stored in MSB order (CMF*256 + FLG),
+         is a multiple of 31.

+
+RFC 1950       ZLIB Compressed Data Format Specification        May 1996
+
+
+      FDICT (Preset dictionary)
+         If FDICT is set, a DICT dictionary identifier is present
+         immediately after the FLG byte. The dictionary is a sequence of
+         bytes which are initially fed to the compressor without
+         producing any compressed output. DICT is the Adler-32 checksum
+         of this sequence of bytes (see the definition of ADLER32
+         below).  The decompressor can use this identifier to determine
+         which dictionary has been used by the compressor.
+
+      FLEVEL (Compression level)
+         These flags are available for use by specific compression
+         methods.  The "deflate" method (CM = 8) sets these flags as
+         follows:
+
+            0 - compressor used fastest algorithm
+            1 - compressor used fast algorithm
+            2 - compressor used default algorithm
+            3 - compressor used maximum compression, slowest algorithm
+
+         The information in FLEVEL is not needed for decompression; it
+         is there to indicate if recompression might be worthwhile.
+
+      compressed data
+         For compression method 8, the compressed data is stored in the
+         deflate compressed data format as described in the document
+         "DEFLATE Compressed Data Format Specification" by L. Peter
+         Deutsch. (See reference [3] in Chapter 3, below)
+
+         Other compressed data formats are not specified in this version
+         of the zlib specification.
+
+      ADLER32 (Adler-32 checksum)
+         This contains a checksum value of the uncompressed data
+         (excluding any dictionary data) computed according to Adler-32
+         algorithm. This algorithm is a 32-bit extension and improvement
+         of the Fletcher algorithm, used in the ITU-T X.224 / ISO 8073
+         standard. See references [4] and [5] in Chapter 3, below)
+
+         Adler-32 is composed of two sums accumulated per byte: s1 is
+         the sum of all bytes, s2 is the sum of all s1 values. Both sums
+         are done modulo 65521. s1 is initialized to 1, s2 to zero.  The
+         Adler-32 checksum is stored as s2*65536 + s1 in most-
+         significant-byte first (network) order.

+
+
+   2.3. Compliance
+
+      A compliant compressor must produce streams with correct CMF, FLG
+      and ADLER32, but need not support preset dictionaries.  When the
+      zlib data format is used as part of another standard data format,
+      the compressor may use only preset dictionaries that are specified
+      by this other data format.  If this other format does not use the
+      preset dictionary feature, the compressor must not set the FDICT
+      flag.
+
+      A compliant decompressor must check CMF, FLG, and ADLER32, and
+      provide an error indication if any of these have incorrect values.
+      A compliant decompressor must give an error indication if CM is
+      not one of the values defined in this specification (only the
+      value 8 is permitted in this version), since another value could
+      indicate the presence of new features that would cause subsequent
+      data to be interpreted incorrectly.  A compliant decompressor must
+      give an error indication if FDICT is set and DICTID is not the
+      identifier of a known preset dictionary.  A decompressor may
+      ignore FLEVEL and still be compliant.  When the zlib data format
+      is being used as a part of another standard format, a compliant
+      decompressor must support all the preset dictionaries specified by
+      the other format. When the other format does not use the preset
+      dictionary feature, a compliant decompressor must reject any
+      stream in which the FDICT flag is set.

+8. Appendix: Rationale
+
+   8.1. Preset dictionaries
+
+      A preset dictionary is specially useful to compress short input
+      sequences. The compressor can take advantage of the dictionary
+      context to encode the input in a more compact manner. The
+      decompressor can be initialized with the appropriate context by
+      virtually decompressing a compressed version of the dictionary
+      without producing any output. However for certain compression
+      algorithms such as the deflate algorithm this operation can be
+      achieved without actually performing any decompression.
+
+      The compressor and the decompressor must use exactly the same
+      dictionary. The dictionary may be fixed or may be chosen among a
+      certain number of predefined dictionaries, according to the kind
+      of input data. The decompressor can determine which dictionary has
+      been chosen by the compressor by checking the dictionary
+      identifier. This document does not specify the contents of
+      predefined dictionaries, since the optimal dictionaries are
+      application specific. Standard data formats using this feature of
+      the zlib specification must precisely define the allowed
+      dictionaries.
+
+   8.2. The Adler-32 algorithm
+
+      The Adler-32 algorithm is much faster than the CRC32 algorithm yet
+      still provides an extremely low probability of undetected errors.
+
+      The modulo on unsigned long accumulators can be delayed for 5552
+      bytes, so the modulo operation time is negligible.  If the bytes
+      are a, b, c, the second sum is 3a + 2b + c + 3, and so is position
+      and order sensitive, unlike the first sum, which is just a
+      checksum.  That 65521 is prime is important to avoid a possible
+      large class of two-byte errors that leave the check unchanged.
+      (The Fletcher checksum uses 255, which is not prime and which also
+      makes the Fletcher check insensitive to single byte changes 0 <->
+      255.)
+
+      The sum s1 is initialized to 1 instead of zero to make the length
+      of the sequence part of s2, so that the length does not have to be
+      checked separately. (Any sequence of zeroes has a Fletcher
+      checksum of zero.)

+
+9. Appendix: Sample code
+
+   The following C code computes the Adler-32 checksum of a data buffer.
+   It is written for clarity, not for speed.  The sample code is in the
+   ANSI C programming language. Non C users may find it easier to read
+   with these hints:
+
+      &      Bitwise AND operator.
+      >>     Bitwise right shift operator. When applied to an
+             unsigned quantity, as here, right shift inserts zero bit(s)
+             at the left.
+      <<     Bitwise left shift operator. Left shift inserts zero
+             bit(s) at the right.
+      ++     "n++" increments the variable n.
+      %      modulo operator: a % b is the remainder of a divided by b.
+
+      #define BASE 65521 /* largest prime smaller than 65536 */
+
+      /*
+         Update a running Adler-32 checksum with the bytes buf[0..len-1]
+       and return the updated checksum. The Adler-32 checksum should be
+       initialized to 1.
+
+       Usage example:
+
+         unsigned long adler = 1L;
+
+         while (read_buffer(buffer, length) != EOF) {
+           adler = update_adler32(adler, buffer, length);
+         }
+         if (adler != original_adler) error();
+      */
+      unsigned long update_adler32(unsigned long adler,
+         unsigned char *buf, int len)
+      {
+        unsigned long s1 = adler & 0xffff;
+        unsigned long s2 = (adler >> 16) & 0xffff;
+        int n;
+
+        for (n = 0; n < len; n++) {
+          s1 = (s1 + buf[n]) % BASE;
+          s2 = (s2 + s1)     % BASE;
+        }
+        return (s2 << 16) + s1;
+      }
+
+      /* Return the adler32 of the bytes buf[0..len-1] */

+1. Introduction
+
+   1.1. Purpose
+
+      The purpose of this specification is to define a lossless
+      compressed data format that:
+          * Is independent of CPU type, operating system, file system,
+            and character set, and hence can be used for interchange;
+          * Can be produced or consumed, even for an arbitrarily long
+            sequentially presented input data stream, using only an a
+            priori bounded amount of intermediate storage, and hence
+            can be used in data communications or similar structures
+            such as Unix filters;
+          * Compresses data with efficiency comparable to the best
+            currently available general-purpose compression methods,
+            and in particular considerably better than the "compress"
+            program;
+          * Can be implemented readily in a manner not covered by
+            patents, and hence can be practiced freely;
+

+
+RFC 1951      DEFLATE Compressed Data Format Specification      May 1996
+
+
+          * Is compatible with the file format produced by the current
+            widely used gzip utility, in that conforming decompressors
+            will be able to read data produced by the existing gzip
+            compressor.
+
+      The data format defined by this specification does not attempt to:
+
+          * Allow random access to compressed data;
+          * Compress specialized data (e.g., raster graphics) as well
+            as the best currently available specialized algorithms.
+
+      A simple counting argument shows that no lossless compression
+      algorithm can compress every possible input data set.  For the
+      format defined here, the worst case expansion is 5 bytes per 32K-
+      byte block, i.e., a size increase of 0.015% for large data sets.
+      English text usually compresses by a factor of 2.5 to 3;
+      executable files usually compress somewhat less; graphical data
+      such as raster images may compress much more.
+
+   1.2. Intended audience
+
+      This specification is intended for use by implementors of software
+      to compress data into "deflate" format and/or decompress data from
+      "deflate" format.
+
+      The text of the specification assumes a basic background in
+      programming at the level of bits and other primitive data
+      representations.  Familiarity with the technique of Huffman coding
+      is helpful but not required.
+
+   1.3. Scope
+
+      The specification specifies a method for representing a sequence
+      of bytes as a (usually shorter) sequence of bits, and a method for
+      packing the latter bit sequence into bytes.
+
+   1.4. Compliance
+
+      Unless otherwise indicated below, a compliant decompressor must be
+      able to accept and decompress any data set that conforms to all
+      the specifications presented here; a compliant compressor must
+      produce data sets that conform to all the specifications presented
+      here.
+
+   1.5.  Definitions of terms and conventions used
+
+      Byte: 8 bits stored or transmitted as a unit (same as an octet).
+      For this specification, a byte is exactly 8 bits, even on machines
+

+
+
+      which store a character on a number of bits different from eight.
+      See below, for the numbering of bits within a byte.
+
+      String: a sequence of arbitrary bytes.
+
+   1.6. Changes from previous versions
+
+      There have been no technical changes to the deflate format since
+      version 1.1 of this specification.  In version 1.2, some
+      terminology was changed.  Version 1.3 is a conversion of the
+      specification to RFC style.
+
+2. Compressed representation overview
+
+   A compressed data set consists of a series of blocks, corresponding
+   to successive blocks of input data.  The block sizes are arbitrary,
+   except that non-compressible blocks are limited to 65,535 bytes.
+
+   Each block is compressed using a combination of the LZ77 algorithm
+   and Huffman coding. The Huffman trees for each block are independent
+   of those for previous or subsequent blocks; the LZ77 algorithm may
+   use a reference to a duplicated string occurring in a previous block,
+   up to 32K input bytes before.
+
+   Each block consists of two parts: a pair of Huffman code trees that
+   describe the representation of the compressed data part, and a
+   compressed data part.  (The Huffman trees themselves are compressed
+   using Huffman encoding.)  The compressed data consists of a series of
+   elements of two types: literal bytes (of strings that have not been
+   detected as duplicated within the previous 32K input bytes), and
+   pointers to duplicated strings, where a pointer is represented as a
+   pair <length, backward distance>.  The representation used in the
+   "deflate" format limits distances to 32K bytes and lengths to 258
+   bytes, but does not limit the size of a block, except for
+   uncompressible blocks, which are limited as noted above.
+
+   Each type of value (literals, distances, and lengths) in the
+   compressed data is represented using a Huffman code, using one code
+   tree for literals and lengths and a separate code tree for distances.
+   The code trees for each block appear in a compact form just before
+   the compressed data for that block.

+3. Detailed specification
+
+   3.1. Overall conventions In the diagrams below, a box like this:
+
+         +---+
+         |   | <-- the vertical bars might be missing
+         +---+
+
+      represents one byte; a box like this:
+
+         +==============+
+         |              |
+         +==============+
+
+      represents a variable number of bytes.
+
+      Bytes stored within a computer do not have a "bit order", since
+      they are always treated as a unit.  However, a byte considered as
+      an integer between 0 and 255 does have a most- and least-
+      significant bit, and since we write numbers with the most-
+      significant digit on the left, we also write bytes with the most-
+      significant bit on the left.  In the diagrams below, we number the
+      bits of a byte so that bit 0 is the least-significant bit, i.e.,
+      the bits are numbered:
+
+         +--------+
+         |76543210|
+         +--------+
+
+      Within a computer, a number may occupy multiple bytes.  All
+      multi-byte numbers in the format described here are stored with
+      the least-significant byte first (at the lower memory address).
+      For example, the decimal number 520 is stored as:
+
+             0        1
+         +--------+--------+
+         |00001000|00000010|
+         +--------+--------+
+          ^        ^
+          |        |
+          |        + more significant byte = 2 x 256
+          + less significant byte = 8
+
+      3.1.1. Packing into bytes
+
+         This document does not address the issue of the order in which
+         bits of a byte are transmitted on a bit-sequential medium,
+         since the final data format described here is byte- rather than
+
+
+
+Deutsch                      Informational                      [Page 5]
+
+RFC 1951      DEFLATE Compressed Data Format Specification      May 1996
+
+
+         bit-oriented.  However, we describe the compressed block format
+         in below, as a sequence of data elements of various bit
+         lengths, not a sequence of bytes.  We must therefore specify
+         how to pack these data elements into bytes to form the final
+         compressed byte sequence:
+
+             * Data elements are packed into bytes in order of
+               increasing bit number within the byte, i.e., starting
+               with the least-significant bit of the byte.
+             * Data elements other than Huffman codes are packed
+               starting with the least-significant bit of the data

+             * Huffman codes are packed starting with the most-
+               significant bit of the code.
+
+         In other words, if one were to print out the compressed data as
+         a sequence of bytes, starting with the first byte at the
+         *right* margin and proceeding to the *left*, with the most-
+         significant bit of each byte on the left as usual, one would be
+         able to parse the result from right to left, with fixed-width
+         elements in the correct MSB-to-LSB order and Huffman codes in
+         bit-reversed order (i.e., with the first bit of the code in the
+         relative LSB position).
+

+
+      3.2.1. Synopsis of prefix and Huffman coding
+
+         Prefix coding represents symbols from an a priori known
+         alphabet by bit sequences (codes), one code for each symbol, in
+         a manner such that different symbols may be represented by bit
+         sequences of different lengths, but a parser can always parse
+         an encoded string unambiguously symbol-by-symbol.
+
+         We define a prefix code in terms of a binary tree in which the
+         two edges descending from each non-leaf node are labeled 0 and
+         1 and in which the leaf nodes correspond one-for-one with (are
+         labeled with) the symbols of the alphabet; then the code for a
+         symbol is the sequence of 0's and 1's on the edges leading from
+         the root to the leaf labeled with that symbol.  For example:

+                       D      C
+
+         A parser can decode the next symbol from an encoded input
+         stream by walking down the tree from the root, at each step
+         choosing the edge corresponding to the next input bit.
+
+         Given an alphabet with known symbol frequencies, the Huffman
+         algorithm allows the construction of an optimal prefix code
+         (one which represents strings with those symbol frequencies
+         using the fewest bits of any possible prefix codes for that
+         alphabet).  Such a code is called a Huffman code.  (See
+         reference [1] in Chapter 5, references for additional
+         information on Huffman codes.)
+
+         Note that in the "deflate" format, the Huffman codes for the
+         various alphabets must not exceed certain maximum code lengths.
+         This constraint complicates the algorithm for computing code
+         lengths from symbol frequencies.  Again, see Chapter 5,
+         references for details.
+
+      3.2.2. Use of Huffman coding in the "deflate" format
+
+         The Huffman codes used for each alphabet in the "deflate"
+         format have two additional rules:
+
+             * All codes of a given bit length have lexicographically
+               consecutive values, in the same order as the symbols
+               they represent;
+
+             * Shorter codes lexicographically precede longer codes.

+
+RFC 1951      DEFLATE Compressed Data Format Specification      May 1996
+
+
+         We could recode the example above to follow this rule as
+         follows, assuming that the order of the alphabet is ABCD:
+
+            Symbol  Code
+            ------  ----
+            A       10
+            B       0
+            C       110
+            D       111
+
+         I.e., 0 precedes 10 which precedes 11x, and 110 and 111 are
+         lexicographically consecutive.
+
+         Given this rule, we can define the Huffman code for an alphabet
+         just by giving the bit lengths of the codes for each symbol of
+         the alphabet in order; this is sufficient to determine the
+         actual codes.  In our example, the code is completely defined
+         by the sequence of bit lengths (2, 1, 3, 3).  The following
+         algorithm generates the codes as integers, intended to be read
+         from most- to least-significant bit.  The code lengths are
+         initially in tree[I].Len; the codes are produced in
+         tree[I].Code.
+
+         1)  Count the number of codes for each code length.  Let
+             bl_count[N] be the number of codes of length N, N >= 1.
+
+         2)  Find the numerical value of the smallest code for each
+             code length:
+
+                code = 0;
+                bl_count[0] = 0;
+                for (bits = 1; bits <= MAX_BITS; bits++) {
+                    code = (code + bl_count[bits-1]) << 1;
+                    next_code[bits] = code;
+                }
+
+         3)  Assign numerical values to all codes, using consecutive
+             values for all codes of the same length with the base
+             values determined at step 2. Codes that are never used
+             (which have a bit length of zero) must not be assigned a
+             value.
+
+                for (n = 0;  n <= max_code; n++) {
+                    len = tree[n].Len;
+                    if (len != 0) {
+                        tree[n].Code = next_code[len];
+                        next_code[len]++;
+                    }

+
+                }
+
+         Example:
+
+         Consider the alphabet ABCDEFGH, with bit lengths (3, 3, 3, 3,
+         3, 2, 4, 4).  After step 1, we have:
+
+            N      bl_count[N]
+            -      -----------
+            2      1
+            3      5
+            4      2
+
+         Step 2 computes the following next_code values:
+
+            N      next_code[N]
+            -      ------------
+            1      0
+            2      0
+            3      2
+            4      14
+
+         Step 3 produces the following code values:
+
+            Symbol Length   Code
+            ------ ------   ----
+            A       3        010

+
+      3.2.3. Details of block format
+
+         Each block of compressed data begins with 3 header bits
+         containing the following data:
+
+            first bit       BFINAL
+            next 2 bits     BTYPE
+
+         Note that the header bits do not necessarily begin on a byte
+         boundary, since a block does not necessarily occupy an integral
+         number of bytes.
+
+

+
+RFC 1951      DEFLATE Compressed Data Format Specification      May 1996
+
+
+         BFINAL is set if and only if this is the last block of the data
+         set.
+
+         BTYPE specifies how the data are compressed, as follows:
+
+            00 - no compression
+            01 - compressed with fixed Huffman codes
+            10 - compressed with dynamic Huffman codes
+            11 - reserved (error)
+
+         The only difference between the two compressed cases is how the
+         Huffman codes for the literal/length and distance alphabets are
+         defined.
+
+         In all cases, the decoding algorithm for the actual data is as
+         follows:
+
+            do
+               read block header from input stream.
+               if stored with no compression
+                  skip any remaining bits in current partially
+                     processed byte
+                  read LEN and NLEN (see next section)
+                  copy LEN bytes of data to output
+               otherwise
+                  if compressed with dynamic Huffman codes
+                     read representation of code trees (see
+                        subsection below)
+                  loop (until end of block code recognized)
+                     decode literal/length value from input stream
+                     if value < 256
+                        copy value (literal byte) to output stream
+                     otherwise
+                        if value = end of block (256)
+                           break from loop
+                        otherwise (value = 257..285)
+                           decode distance from input stream
+
+                           move backwards distance bytes in the output
+                           stream, and copy length bytes from this
+                           position to the output stream.
+                  end loop
+            while not last block
+
+         Note that a duplicated string reference may refer to a string
+         in a previous block; i.e., the backward distance may cross one
+         or more block boundaries.  However a distance cannot refer past
+         the beginning of the output stream.  (An application using a
+

+Deutsch                      Informational                     [Page 10]

+
+
+         preset dictionary might discard part of the output stream; a
+         distance can refer to that part of the output stream anyway)
+         Note also that the referenced string may overlap the current
+         position; for example, if the last 2 bytes decoded have values
+         X and Y, a string reference with <length = 5, distance = 2>
+         adds X,Y,X,Y,X to the output stream.
+
+         We now specify each compression method in turn.
+
+      3.2.4. Non-compressed blocks (BTYPE=00)
+
+         Any bits of input up to the next byte boundary are ignored.
+         The rest of the block consists of the following information:
+
+              0   1   2   3   4...
+            +---+---+---+---+================================+
+            |  LEN  | NLEN  |... LEN bytes of literal data...|
+            +---+---+---+---+================================+
+
+         LEN is the number of data bytes in the block.  NLEN is the
+         one's complement of LEN.
+
+      3.2.5. Compressed blocks (length and distance codes)
+
+         As noted above, encoded data blocks in the "deflate" format
+         consist of sequences of symbols drawn from three conceptually
+         distinct alphabets: either literal bytes, from the alphabet of
+         byte values (0..255), or <length, backward distance> pairs,
+         where the length is drawn from (3..258) and the distance is
+         drawn from (1..32,768).  In fact, the literal and length
+         alphabets are merged into a single alphabet (0..285), where
+         values 0..255 represent literal bytes, the value 256 indicates
+         end-of-block, and values 257..285 represent length codes
+         (possibly in conjunction with extra bits following the symbol
+         code) as follows:

+
+
+         The code lengths are sufficient to generate the actual codes,
+         as described above; we show the codes in the table for added
+         clarity.  Literal/length values 286-287 will never actually
+         occur in the compressed data, but participate in the code
+         construction.
+
+         Distance codes 0-31 are represented by (fixed-length) 5-bit
+         codes, with possible additional bits as shown in the table
+         shown in Paragraph 3.2.5, above.  Note that distance codes 30-
+         31 will never actually occur in the compressed data.
+
+      3.2.7. Compression with dynamic Huffman codes (BTYPE=10)
+
+         The Huffman codes for the two alphabets appear in the block
+         immediately after the header bits and before the actual
+         compressed data, first the literal/length code and then the
+         distance code.  Each code is defined by a sequence of code
+         lengths, as discussed in Paragraph 3.2.2, above.  For even
+         greater compactness, the code length sequences themselves are
+         compressed using a Huffman code.  The alphabet for code lengths
+         is as follows:
+
+               0 - 15: Represent code lengths of 0 - 15
+                   16: Copy the previous code length 3 - 6 times.
+                       The next 2 bits indicate repeat length
+                             (0 = 3, ... , 3 = 6)
+                          Example:  Codes 8, 16 (+2 bits 11),
+                                    16 (+2 bits 10) will expand to
+                                    12 code lengths of 8 (1 + 6 + 5)
+                   17: Repeat a code length of 0 for 3 - 10 times.
+                       (3 bits of length)
+                   18: Repeat a code length of 0 for 11 - 138 times
+                       (7 bits of length)
+
+         A code length of 0 indicates that the corresponding symbol in
+         the literal/length or distance alphabet will not occur in the
+         block, and should not participate in the Huffman code
+         construction algorithm given earlier.  If only one distance
+         code is used, it is encoded using one bit, not zero bits; in
+         this case there is a single code length of one, with one unused
+         code.  One distance code of zero bits means that there are no
+         distance codes used at all (the data is all literals).
+
+         We can now define the format of the block:
+
+               5 Bits: HLIT, # of Literal/Length codes - 257 (257 - 286)
+               5 Bits: HDIST, # of Distance codes - 1        (1 - 32)
+               4 Bits: HCLEN, # of Code Length codes - 4     (4 - 19)
+
+

+
+RFC 1951      DEFLATE Compressed Data Format Specification      May 1996
+
+
+               (HCLEN + 4) x 3 bits: code lengths for the code length
+                  alphabet given just above, in the order: 16, 17, 18,
+                  0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15
+
+                  These code lengths are interpreted as 3-bit integers
+                  (0-7); as above, a code length of 0 means the
+                  corresponding symbol (literal/length or distance code
+                  length) is not used.
+
+               HLIT + 257 code lengths for the literal/length alphabet,
+                  encoded using the code length Huffman code
+
+               HDIST + 1 code lengths for the distance alphabet,
+                  encoded using the code length Huffman code
+
+               The actual compressed data of the block,
+                  encoded using the literal/length and distance Huffman
+                  codes
+
+               The literal/length symbol 256 (end of data),
+                  encoded using the literal/length Huffman code
+
+         The code length repeat codes can cross from HLIT + 257 to the
+         HDIST + 1 code lengths.  In other words, all code lengths form
+         a single sequence of HLIT + HDIST + 258 values.
+
+   3.3. Compliance
+
+      A compressor may limit further the ranges of values specified in
+      the previous section and still be compliant; for example, it may
+      limit the range of backward pointers to some value smaller than
+      32K.  Similarly, a compressor may limit the size of blocks so that
+      a compressible block fits in memory.
+
+      A compliant decompressor must accept the full range of possible
+      values defined in the previous section, and must accept blocks of
+      arbitrary size.
+
+4. Compression algorithm details
+
+   While it is the intent of this document to define the "deflate"
+   compressed data format without reference to any particular
+   compression algorithm, the format is related to the compressed
+   formats produced by LZ77 (Lempel-Ziv 1977, see reference [2] below);
+   since many variations of LZ77 are patented, it is strongly
+   recommended that the implementor of a compressor follow the general
+   algorithm presented here, which is known not to be patented per se.
+   The material in this section is not part of the definition of the
+
+
+
+Deutsch                      Informational                     [Page 14]
+
+RFC 1951      DEFLATE Compressed Data Format Specification      May 1996
+
+
+   specification per se, and a compressor need not follow it in order to
+   be compliant.
+
+   The compressor terminates a block when it determines that starting a
+   new block with fresh trees would be useful, or when the block size
+   fills up the compressor's block buffer.
+
+   The compressor uses a chained hash table to find duplicated strings,
+   using a hash function that operates on 3-byte sequences.  At any
+   given point during compression, let XYZ be the next 3 input bytes to
+   be examined (not necessarily all different, of course).  First, the
+   compressor examines the hash chain for XYZ.  If the chain is empty,
+   the compressor simply writes out X as a literal byte and advances one
+   byte in the input.  If the hash chain is not empty, indicating that
+   the sequence XYZ (or, if we are unlucky, some other 3 bytes with the
+   same hash function value) has occurred recently, the compressor
+   compares all strings on the XYZ hash chain with the actual input data
+   sequence starting at the current point, and selects the longest
+   match.
+
+   The compressor searches the hash chains starting with the most recent
+   strings, to favor small distances and thus take advantage of the
+   Huffman encoding.  The hash chains are singly linked. There are no
+   deletions from the hash chains; the algorithm simply discards matches
+   that are too old.  To avoid a worst-case situation, very long hash
+   chains are arbitrarily truncated at a certain length, determined by a
+   run-time parameter.
+
+   To improve overall compression, the compressor optionally defers the
+   selection of matches ("lazy matching"): after a match of length N has
+   been found, the compressor searches for a longer match starting at
+   the next input byte.  If it finds a longer match, it truncates the
+   previous match to a length of one (thus producing a single literal
+   byte) and then emits the longer match.  Otherwise, it emits the
+   original match, and, as described above, advances N bytes before
+   continuing.
+
+   Run-time parameters also control this "lazy match" procedure.  If
+   compression ratio is most important, the compressor attempts a
+   complete second search regardless of the length of the first match.
+   In the normal case, if the current match is "long enough", the
+   compressor reduces the search for a longer match, thus speeding up
+   the process.  If speed is most important, the compressor inserts new
+   strings in the hash table only when no match was found, or when the
+   match is not "too long".  This degrades the compression ratio but
+   saves time since there are both fewer insertions and fewer searches.

+   the other hand, will probably still be readable despite the presence
+   of some corrupted bytes.

+   It is recommended that systems using this data format provide some

+Abstract
+
+   This specification defines a lossless compressed data format that is
+   compatible with the widely used GZIP utility.  The format includes a
+   cyclic redundancy check value for detecting data corruption.  The
+   format presently uses the DEFLATE method of compression but can be
+   easily extended to use other compression methods.  The format can be
+   implemented readily in a manner not covered by patents.

+1. Introduction
+
+   1.1. Purpose
+
+      The purpose of this specification is to define a lossless
+      compressed data format that:
+
+          * Is independent of CPU type, operating system, file system,
+            and character set, and hence can be used for interchange;
+          * Can compress or decompress a data stream (as opposed to a
+            randomly accessible file) to produce another data stream,
+            using only an a priori bounded amount of intermediate
+            storage, and hence can be used in data communications or
+            similar structures such as Unix filters;
+          * Compresses data with efficiency comparable to the best
+            currently available general-purpose compression methods,
+            and in particular considerably better than the "compress"
+            program;
+          * Can be implemented readily in a manner not covered by
+            patents, and hence can be practiced freely;
+          * Is compatible with the file format produced by the current
+            widely used gzip utility, in that conforming decompressors
+            will be able to read data produced by the existing gzip
+            compressor.

+RFC 1952             GZIP File Format Specification             May 1996
+
+
+      The data format defined by this specification does not attempt to:
+
+          * Provide random access to compressed data;
+          * Compress specialized data (e.g., raster graphics) as well as
+            the best currently available specialized algorithms.
+
+   1.2. Intended audience
+
+      This specification is intended for use by implementors of software
+      to compress data into gzip format and/or decompress data from gzip
+      format.
+
+      The text of the specification assumes a basic background in
+      programming at the level of bits and other primitive data
+      representations.
+
+   1.3. Scope
+
+      The specification specifies a compression method and a file format
+      (the latter assuming only that a file can store a sequence of
+      arbitrary bytes).  It does not specify any particular interface to
+      a file system or anything about character sets or encodings
+      (except for file names and comments, which are optional).
+
+   1.4. Compliance
+
+      Unless otherwise indicated below, a compliant decompressor must be
+      able to accept and decompress any file that conforms to all the
+      specifications presented here; a compliant compressor must produce
+      files that conform to all the specifications presented here.  The
+      material in the appendices is not part of the specification per se
+      and is not relevant to compliance.
+
+   1.5. Definitions of terms and conventions used
+
+      byte: 8 bits stored or transmitted as a unit (same as an octet).
+      (For this specification, a byte is exactly 8 bits, even on
+      machines which store a character on a number of bits different
+      from 8.)  See below for the numbering of bits within a byte.
+
+   1.6. Changes from previous versions
+
+      There have been no technical changes to the gzip format since
+      version 4.1 of this specification.  In version 4.2, some
+      terminology was changed, and the sample CRC code was rewritten for
+      clarity and to eliminate the requirement for the caller to do pre-
+      and post-conditioning.  Version 4.3 is a conversion of the
+      specification to RFC style.

+2. Detailed specification
+
+   2.1. Overall conventions
+
+      In the diagrams below, a box like this:
+
+         +---+
+         |   | <-- the vertical bars might be missing
+         +---+
+
+      represents one byte; a box like this:
+
+         +==============+
+         |              |
+         +==============+
+
+      represents a variable number of bytes.
+
+      Bytes stored within a computer do not have a "bit order", since
+      they are always treated as a unit.  However, a byte considered as
+      an integer between 0 and 255 does have a most- and least-
+      significant bit, and since we write numbers with the most-
+      significant digit on the left, we also write bytes with the most-
+      significant bit on the left.  In the diagrams below, we number the
+      bits of a byte so that bit 0 is the least-significant bit, i.e.,
+      the bits are numbered:
+
+         +--------+
+         |76543210|
+         +--------+
+
+      This document does not address the issue of the order in which
+      bits of a byte are transmitted on a bit-sequential medium, since
+      the data format described here is byte- rather than bit-oriented.
+
+      Within a computer, a number may occupy multiple bytes.  All
+      multi-byte numbers in the format described here are stored with
+      the least-significant byte first (at the lower memory address).
+      For example, the decimal number 520 is stored as:
+

+
+   2.2. File format
+
+      A gzip file consists of a series of "members" (compressed data
+      sets).  The format of each member is specified in the following
+      section.  The members simply appear one after another in the file,
+      with no additional information before, between, or after them.
+
+   2.3. Member format
+
+      Each member has the following structure:
+
+         +---+---+---+---+---+---+---+---+---+---+
+         |ID1|ID2|CM |FLG|     MTIME     |XFL|OS | (more-->)
+         +---+---+---+---+---+---+---+---+---+---+

+         | XLEN  |...XLEN bytes of "extra field"...| (more-->)
+         +---+---+=================================+
+
+      (if FLG.FNAME set)
+
+         +=========================================+
+         |...original file name, zero-terminated...| (more-->)
+         +=========================================+
+
+      (if FLG.FCOMMENT set)

+         +===================================+

+
+
+      2.3.1. Member header and trailer
+
+         ID1 (IDentification 1)
+         ID2 (IDentification 2)
+            These have the fixed values ID1 = 31 (0x1f, \037), ID2 = 139
+            (0x8b, \213), to identify the file as being in gzip format.
+
+         CM (Compression Method)
+            This identifies the compression method used in the file.  CM
+            = 0-7 are reserved.  CM = 8 denotes the "deflate"
+            compression method, which is the one customarily used by
+            gzip and which is documented elsewhere.
+
+         FLG (FLaGs)
+            This flag byte is divided into individual bits as follows:
+
+               bit 0   FTEXT
+               bit 1   FHCRC
+               bit 2   FEXTRA
+               bit 3   FNAME
+               bit 4   FCOMMENT
+               bit 5   reserved
+               bit 6   reserved
+               bit 7   reserved
+
+            If FTEXT is set, the file is probably ASCII text.  This is
+            an optional indication, which the compressor may set by
+            checking a small amount of the input data to see whether any
+            non-ASCII characters are present.  In case of doubt, FTEXT
+            is cleared, indicating binary data. For systems which have
+            different file formats for ascii text and binary data, the
+            decompressor can use FTEXT to choose the appropriate format.
+            We deliberately do not specify the algorithm used to set
+            this bit, since a compressor always has the option of
+            leaving it cleared and a decompressor always has the option
+            of ignoring it and letting some other program handle issues
+            of data conversion.
+
+            If FHCRC is set, a CRC16 for the gzip header is present,
+            immediately before the compressed data. The CRC16 consists
+            of the two least significant bytes of the CRC32 for all
+            bytes of the gzip header up to and not including the CRC16.
+            [The FHCRC bit was never set by versions of gzip up to
+            1.2.4, even though it was documented with a different
+            meaning in gzip 1.2.4.]
+
+            If FEXTRA is set, optional extra fields are present, as
+            described in a following section.

+RFC 1952             GZIP File Format Specification             May 1996
+
+
+            If FNAME is set, an original file name is present,
+            terminated by a zero byte.  The name must consist of ISO
+            8859-1 (LATIN-1) characters; on operating systems using
+            EBCDIC or any other character set for file names, the name
+            must be translated to the ISO LATIN-1 character set.  This
+            is the original name of the file being compressed, with any
+            directory components removed, and, if the file being
+            compressed is on a file system with case insensitive names,
+            forced to lower case. There is no original file name if the
+            data was compressed from a source other than a named file;
+            for example, if the source was stdin on a Unix system, there
+            is no file name.
+
+            If FCOMMENT is set, a zero-terminated file comment is
+            present.  This comment is not interpreted; it is only
+            intended for human consumption.  The comment must consist of
+            ISO 8859-1 (LATIN-1) characters.  Line breaks should be
+            denoted by a single line feed character (10 decimal).
+
+            Reserved FLG bits must be zero.
+
+         MTIME (Modification TIME)
+            This gives the most recent modification time of the original
+            file being compressed.  The time is in Unix format, i.e.,
+            seconds since 00:00:00 GMT, Jan.  1, 1970.  (Note that this
+            may cause problems for MS-DOS and other systems that use
+            local rather than Universal time.)  If the compressed data
+            did not come from a file, MTIME is set to the time at which
+            compression started.  MTIME = 0 means no time stamp is
+            available.
+
+         XFL (eXtra FLags)
+            These flags are available for use by specific compression
+            methods.  The "deflate" method (CM = 8) sets these flags as
+            follows:
+
+               XFL = 2 - compressor used maximum compression,
+                         slowest algorithm
+               XFL = 4 - compressor used fastest algorithm
+
+         OS (Operating System)
+            This identifies the type of file system on which compression
+            took place.  This may be useful in determining end-of-line
+            convention for text files.  The currently defined values are
+            as follows:

+            If FLG.FEXTRA is set, this gives the length of the optional
+            extra field.  See below for details.
+
+         CRC32 (CRC-32)
+            This contains a Cyclic Redundancy Check value of the
+            uncompressed data computed according to CRC-32 algorithm
+            used in the ISO 3309 standard and in section 8.1.1.6.2 of
+            ITU-T recommendation V.42.  (See http://www.iso.ch for
+            ordering ISO documents. See gopher://info.itu.ch for an
+            online version of ITU-T V.42.)
+
+         ISIZE (Input SIZE)
+            This contains the size of the original (uncompressed) input
+            data modulo 2^32.
+
+      2.3.1.1. Extra field
+
+         If the FLG.FEXTRA bit is set, an "extra field" is present in
+         the header, with total length XLEN bytes.  It consists of a
+         series of subfields, each of the form:
+
+            +---+---+---+---+==================================+
+            |SI1|SI2|  LEN  |... LEN bytes of subfield data ...|
+            +---+---+---+---+==================================+
+
+         SI1 and SI2 provide a subfield ID, typically two ASCII letters
+         with some mnemonic value.  Jean-Loup Gailly
+         <gzip@prep.ai.mit.edu> is maintaining a registry of subfield
+         IDs; please send him any subfield ID you wish to use.  Subfield
+         IDs with SI2 = 0 are reserved for future use.  The following
+         IDs are currently defined:

+
+         LEN gives the length of the subfield data, excluding the 4
+         initial bytes.
+
+      2.3.1.2. Compliance
+
+         A compliant compressor must produce files with correct ID1,
+         ID2, CM, CRC32, and ISIZE, but may set all the other fields in
+         the fixed-length part of the header to default values (255 for
+         OS, 0 for all others).  The compressor must set all reserved
+         bits to zero.
+
+         A compliant decompressor must check ID1, ID2, and CM, and
+         provide an error indication if any of these have incorrect
+         values.  It must examine FEXTRA/XLEN, FNAME, FCOMMENT and FHCRC
+         at least so it can skip over the optional fields if they are
+         present.  It need not examine any other part of the header or
+         trailer; in particular, a decompressor may ignore FTEXT and OS
+         and always produce binary output, and still be compliant.  A
+         compliant decompressor must give an error indication if any
+         reserved bit is non-zero, since such a bit could indicate the
+         presence of a new field that would cause subsequent data to be
+         interpreted incorrectly.

+4. Security Considerations
+
+   Any data compression method involves the reduction of redundancy in
+   the data.  Consequently, any corruption of the data is likely to have
+   severe effects and be difficult to correct.  Uncompressed text, on
+   the other hand, will probably still be readable despite the presence
+   of some corrupted bytes.
+
+   It is recommended that systems using this data format provide some
+   means of validating the integrity of the compressed data, such as by
+   setting and checking the CRC-32 check value.

+7. Appendix: Jean-Loup Gailly's gzip utility
+
+   The most widely used implementation of gzip compression, and the
+   original documentation on which this specification is based, were
+   created by Jean-Loup Gailly <gzip@prep.ai.mit.edu>.  Since this
+   implementation is a de facto standard, we mention some more of its
+   features here.  Again, the material in this section is not part of
+   the specification per se, and implementations need not follow it to
+   be compliant.
+
+   When compressing or decompressing a file, gzip preserves the
+   protection, ownership, and modification time attributes on the local
+   file system, since there is no provision for representing protection
+   attributes in the gzip file format itself.  Since the file format
+   includes a modification time, the gzip decompressor provides a
+   command line switch that assigns the modification time from the file,
+   rather than the local modification time of the compressed input, to
+   the decompressed output.
+
+8. Appendix: Sample CRC Code
+
+   The following sample code represents a practical implementation of
+   the CRC (Cyclic Redundancy Check). (See also ISO 3309 and ITU-T V.42
+   for a formal specification.)
+
+   The sample code is in the ANSI C programming language. Non C users
+   may find it easier to read with these hints:
+
+      &      Bitwise AND operator.
+      ^      Bitwise exclusive-OR operator.
+      >>     Bitwise right shift operator. When applied to an
+             unsigned quantity, as here, right shift inserts zero
+             bit(s) at the left.
+      !      Logical NOT operator.
+      ++     "n++" increments the variable n.
+      0xNNN  0x introduces a hexadecimal (base 16) constant.
+             Suffix L indicates a long value (at least 32 bits).

+A Fast Method for Identifying Plain Text Files
+==============================================
+
+
+Introduction
+------------
+
+Given a file coming from an unknown source, it is sometimes desirable
+to find out whether the format of that file is plain text.  Although
+this may appear like a simple task, a fully accurate detection of the
+file type requires heavy-duty semantic analysis on the file contents.
+It is, however, possible to obtain satisfactory results by employing
+various heuristics.
+
+Previous versions of PKZip and other zip-compatible compression tools
+were using a crude detection scheme: if more than 80% (4/5) of the bytes
+found in a certain buffer are within the range [7..127], the file is
+labeled as plain text, otherwise it is labeled as binary.  A prominent
+limitation of this scheme is the restriction to Latin-based alphabets.
+Other alphabets, like Greek, Cyrillic or Asian, make extensive use of
+the bytes within the range [128..255], and texts using these alphabets
+are most often misidentified by this scheme; in other words, the rate
+of false negatives is sometimes too high, which means that the recall
+is low.  Another weakness of this scheme is a reduced precision, due to
+the false positives that may occur when binary files containing large
+amounts of textual characters are misidentified as plain text.
+
+In this article we propose a new, simple detection scheme that features
+a much increased precision and a near-100% recall.  This scheme is
+designed to work on ASCII, Unicode and other ASCII-derived alphabets,
+and it handles single-byte encodings (ISO-8859, MacRoman, KOI8, etc.)
+and variable-sized encodings (ISO-2022, UTF-8, etc.).  Wider encodings
+(UCS-2/UTF-16 and UCS-4/UTF-32) are not handled, however.
+
+
+The Algorithm
+-------------
+
+The algorithm works by dividing the set of bytecodes [0..255] into three
+categories:
+- The white list of textual bytecodes:
+  9 (TAB), 10 (LF), 13 (CR), 32 (SPACE) to 255.
+- The gray list of tolerated bytecodes:
+  7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB), 27 (ESC).
+- The black list of undesired, non-textual bytecodes:
+  0 (NUL) to 6, 14 to 31.
+
+If a file contains at least one byte that belongs to the white list and
+no byte that belongs to the black list, then the file is categorized as
+plain text; otherwise, it is categorized as binary.  (The boundary case,
+when the file is empty, automatically falls into the latter category.)
+
+
+Rationale
+---------
+
+The idea behind this algorithm relies on two observations.
+
+The first observation is that, although the full range of 7-bit codes
+[0..127] is properly specified by the ASCII standard, most control
+characters in the range [0..31] are not used in practice.  The only
+widely-used, almost universally-portable control codes are 9 (TAB),
+10 (LF) and 13 (CR).  There are a few more control codes that are
+recognized on a reduced range of platforms and text viewers/editors:
+7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB) and 27 (ESC); but these
+codes are rarely (if ever) used alone, without being accompanied by
+some printable text.  Even the newer, portable text formats such as
+XML avoid using control characters outside the list mentioned here.
+
+The second observation is that most of the binary files tend to contain
+control characters, especially 0 (NUL).  Even though the older text
+detection schemes observe the presence of non-ASCII codes from the range
+[128..255], the precision rarely has to suffer if this upper range is
+labeled as textual, because the files that are genuinely binary tend to
+contain both control characters and codes from the upper range.  On the
+other hand, the upper range needs to be labeled as textual, because it
+is used by virtually all ASCII extensions.  In particular, this range is
+used for encoding non-Latin scripts.
+
+Since there is no counting involved, other than simply observing the
+presence or the absence of some byte values, the algorithm produces
+consistent results, regardless what alphabet encoding is being used.
+(If counting were involved, it could be possible to obtain different
+results on a text encoded, say, using ISO-8859-16 versus UTF-8.)
+
+There is an extra category of plain text files that are "polluted" with
+one or more black-listed codes, either by mistake or by peculiar design
+considerations.  In such cases, a scheme that tolerates a small fraction
+of black-listed codes would provide an increased recall (i.e. more true
+positives).  This, however, incurs a reduced precision overall, since
+false positives are more likely to appear in binary files that contain
+large chunks of textual data.  Furthermore, "polluted" plain text should
+be regarded as binary by general-purpose text detection schemes, because
+general-purpose text processing algorithms might not be applicable.
+Under this premise, it is safe to say that our detection method provides
+a near-100% recall.
+
+Experiments have been run on many files coming from various platforms
+and applications.  We tried plain text files, system logs, source code,
+formatted office documents, compiled object code, etc.  The results
+confirm the optimistic assumptions about the capabilities of this
+algorithm.

+/*
+   Examine all possible Huffman codes for a given number of symbols and a
+   maximum code length in bits to determine the maximum table size for zilb's
+   inflate.  Only complete Huffman codes are counted.
+
+   Two codes are considered distinct if the vectors of the number of codes per
+   length are not identical.  So permutations of the symbol assignments result
+   in the same code for the counting, as do permutations of the assignments of
+   the bit values to the codes (i.e. only canonical codes are counted).
+
+   We build a code from shorter to longer lengths, determining how many symbols
+   are coded at each length.  At each step, we have how many symbols remain to
+   be coded, what the last code length used was, and how many bit patterns of
+   that length remain unused. Then we add one to the code length and double the
+   number of unused patterns to graduate to the next code length.  We then
+   assign all portions of the remaining symbols to that code length that
+   preserve the properties of a correct and eventually complete code.  Those
+   properties are: we cannot use more bit patterns than are available; and when
+   all the symbols are used, there are exactly zero possible bit patterns
+   remaining.
+
+   The inflate Huffman decoding algorithm uses two-level lookup tables for
+   speed.  There is a single first-level table to decode codes up to root bits
+   in length (root == 9 in the current inflate implementation).  The table
+   has 1 << root entries and is indexed by the next root bits of input.  Codes
+   shorter than root bits have replicated table entries, so that the correct
+   entry is pointed to regardless of the bits that follow the short code.  If
+   the code is longer than root bits, then the table entry points to a second-
+   level table.  The size of that table is determined by the longest code with
+   that root-bit prefix.  If that longest code has length len, then the table
+   has size 1 << (len - root), to index the remaining bits in that set of
+   codes.  Each subsequent root-bit prefix then has its own sub-table.  The
+   total number of table entries required by the code is calculated
+   incrementally as the number of codes at each bit length is populated.  When
+   all of the codes are shorter than root bits, then root is reduced to the
+   longest code length, resulting in a single, smaller, one-level table.
+
+   The inflate algorithm also provides for small values of root (relative to
+   the log2 of the number of symbols), where the shortest code has more bits
+   than root.  In that case, root is increased to the length of the shortest
+   code.  This program, by design, does not handle that case, so it is verified
+   that the number of symbols is less than 2^(root + 1).
+
+   In order to speed up the examination (by about ten orders of magnitude for
+   the default arguments), the intermediate states in the build-up of a code
+   are remembered and previously visited branches are pruned.  The memory
+   required for this will increase rapidly with the total number of symbols and
+   the maximum code length in bits.  However this is a very small price to pay
+   for the vast speedup.
+
+   First, all of the possible Huffman codes are counted, and reachable
+   intermediate states are noted by a non-zero count in a saved-results array.
+   Second, the intermediate states that lead to (root + 1) bit or longer codes
+   are used to look at all sub-codes from those junctures for their inflate
+   memory usage.  (The amount of memory used is not affected by the number of
+   codes of root bits or less in length.)  Third, the visited states in the
+   construction of those sub-codes and the associated calculation of the table
+   size is recalled in order to avoid recalculating from the same juncture.
+   Beginning the code examination at (root + 1) bit codes, which is enabled by
+   identifying the reachable nodes, accounts for about six of the orders of
+   magnitude of improvement for the default arguments.  About another four
+   orders of magnitude come from not revisiting previous states.  Out of
+   approximately 2x10^16 possible Huffman codes, only about 2x10^6 sub-codes
+   need to be examined to cover all of the possible table memory usage cases
+   for the default arguments of 286 symbols limited to 15-bit codes.
+
+   Note that an unsigned long long type is used for counting.  It is quite easy
+   to exceed the capacity of an eight-byte integer with a large number of
+   symbols and a large maximum code length, so multiple-precision arithmetic
+   would need to replace the unsigned long long arithmetic in that case.  This
+   program will abort if an overflow occurs.  The big_t type identifies where
+   the counting takes place.
+
+   An unsigned long long type is also used for calculating the number of
+   possible codes remaining at the maximum length.  This limits the maximum
+   code length to the number of bits in a long long minus the number of bits
+   needed to represent the symbols in a flat code.  The code_t type identifies
+   where the bit pattern counting takes place.

+/*
+   gzlog provides a mechanism for frequently appending short strings to a gzip
+   file that is efficient both in execution time and compression ratio.  The
+   strategy is to write the short strings in an uncompressed form to the end of
+   the gzip file, only compressing when the amount of uncompressed data has
+   reached a given threshold.
+
+   gzlog also provides protection against interruptions in the process due to
+   system crashes.  The status of the operation is recorded in an extra field
+   in the gzip file, and is only updated once the gzip file is brought to a
+   valid state.  The last data to be appended or compressed is saved in an
+   auxiliary file, so that if the operation is interrupted, it can be completed
+   the next time an append operation is attempted.
+
+   gzlog maintains another auxiliary file with the last 32K of data from the
+   compressed portion, which is preloaded for the compression of the subsequent
+   data.  This minimizes the impact to the compression ratio of appending.
+ */
+
+/*
+   Operations Concept:
+
+   Files (log name "foo"):
+   foo.gz -- gzip file with the complete log
+   foo.add -- last message to append or last data to compress
+   foo.dict -- dictionary of the last 32K of data for next compression
+   foo.temp -- temporary dictionary file for compression after this one
+   foo.lock -- lock file for reading and writing the other files
+   foo.repairs -- log file for log file recovery operations (not compressed)
+
+   gzip file structure:
+   - fixed-length (no file name) header with extra field (see below)
+   - compressed data ending initially with empty stored block
+   - uncompressed data filling out originally empty stored block and
+     subsequent stored blocks as needed (16K max each)
+   - gzip trailer
+   - no junk at end (no other gzip streams)
+
+   When appending data, the information in the first three items above plus the
+   foo.add file are sufficient to recover an interrupted append operation.  The
+   extra field has the necessary information to restore the start of the last
+   stored block and determine where to append the data in the foo.add file, as
+   well as the crc and length of the gzip data before the append operation.
+
+   The foo.add file is created before the gzip file is marked for append, and
+   deleted after the gzip file is marked as complete.  So if the append
+   operation is interrupted, the data to add will still be there.  If due to
+   some external force, the foo.add file gets deleted between when the append
+   operation was interrupted and when recovery is attempted, the gzip file will
+   still be restored, but without the appended data.
+
+   When compressing data, the information in the first two items above plus the
+   foo.add file are sufficient to recover an interrupted compress operation.
+   The extra field has the necessary information to find the end of the
+   compressed data, and contains both the crc and length of just the compressed
+   data and of the complete set of data including the contents of the foo.add
+   file.
+
+   Again, the foo.add file is maintained during the compress operation in case
+   of an interruption.  If in the unlikely event the foo.add file with the data
+   to be compressed is missing due to some external force, a gzip file with
+   just the previous compressed data will be reconstructed.  In this case, all
+   of the data that was to be compressed is lost (approximately one megabyte).
+   This will not occur if all that happened was an interruption of the compress
+   operation.
+
+   The third state that is marked is the replacement of the old dictionary with
+   the new dictionary after a compress operation.  Once compression is
+   complete, the gzip file is marked as being in the replace state.  This
+   completes the gzip file, so an interrupt after being so marked does not
+   result in recompression.  Then the dictionary file is replaced, and the gzip
+   file is marked as completed.  This state prevents the possibility of
+   restarting compression with the wrong dictionary file.
+
+   All three operations are wrapped by a lock/unlock procedure.  In order to
+   gain exclusive access to the log files, first a foo.lock file must be
+   exclusively created.  When all operations are complete, the lock is
+   released by deleting the foo.lock file.  If when attempting to create the
+   lock file, it already exists and the modify time of the lock file is more
+   than five minutes old (set by the PATIENCE define below), then the old
+   lock file is considered stale and deleted, and the exclusive creation of
+   the lock file is retried.  To assure that there are no false assessments
+   of the staleness of the lock file, the operations periodically touch the
+   lock file to update the modified date.
+
+   Following is the definition of the extra field with all of the information
+   required to enable the above append and compress operations and their
+   recovery if interrupted.  Multi-byte values are stored little endian
+   (consistent with the gzip format).  File pointers are eight bytes long.
+   The crc's and lengths for the gzip trailer are four bytes long.  (Note that
+   the length at the end of a gzip file is used for error checking only, and
+   for large files is actually the length modulo 2^32.)  The stored block
+   length is two bytes long.  The gzip extra field two-byte identification is
+   "ap" for append.  It is assumed that writing the extra field to the file is
+   an "atomic" operation.  That is, either all of the extra field is written
+   to the file, or none of it is, if the operation is interrupted right at the
+   point of updating the extra field.  This is a reasonable assumption, since
+   the extra field is within the first 52 bytes of the file, which is smaller
+   than any expected block size for a mass storage device (usually 512 bytes or
+   larger).
+
+   Extra field (35 bytes):
+   - Pointer to first stored block length -- this points to the two-byte length
+     of the first stored block, which is followed by the two-byte, one's
+     complement of that length.  The stored block length is preceded by the
+     three-bit header of the stored block, which is the actual start of the
+     stored block in the deflate format.  See the bit offset field below.
+   - Pointer to the last stored block length.  This is the same as above, but
+     for the last stored block of the uncompressed data in the gzip file.
+     Initially this is the same as the first stored block length pointer.
+     When the stored block gets to 16K (see the MAX_STORE define), then a new
+     stored block as added, at which point the last stored block length pointer
+     is different from the first stored block length pointer.  When they are
+     different, the first bit of the last stored block header is eight bits, or
+     one byte back from the block length.
+   - Compressed data crc and length.  This is the crc and length of the data
+     that is in the compressed portion of the deflate stream.  These are used
+     only in the event that the foo.add file containing the data to compress is
+     lost after a compress operation is interrupted.
+   - Total data crc and length.  This is the crc and length of all of the data
+     stored in the gzip file, compressed and uncompressed.  It is used to
+     reconstruct the gzip trailer when compressing, as well as when recovering
+     interrupted operations.
+   - Final stored block length.  This is used to quickly find where to append,
+     and allows the restoration of the original final stored block state when
+     an append operation is interrupted.
+   - First stored block start as the number of bits back from the final stored
+     block first length byte.  This value is in the range of 3..10, and is
+     stored as the low three bits of the final byte of the extra field after
+     subtracting three (0..7).  This allows the last-block bit of the stored
+     block header to be updated when a new stored block is added, for the case
+     when the first stored block and the last stored block are the same.  (When
+     they are different, the numbers of bits back is known to be eight.)  This
+     also allows for new compressed data to be appended to the old compressed
+     data in the compress operation, overwriting the previous first stored
+     block, or for the compressed data to be terminated and a valid gzip file
+     reconstructed on the off chance that a compression operation was
+     interrupted and the data to compress in the foo.add file was deleted.
+   - The operation in process.  This is the next two bits in the last byte (the
+     bits under the mask 0x18).  The are interpreted as 0: nothing in process,
+     1: append in process, 2: compress in process, 3: replace in process.
+   - The top three bits of the last byte in the extra field are reserved and
+     are currently set to zero.
+
+   Main procedure:
+   - Exclusively create the foo.lock file using the O_CREAT and O_EXCL modes of
+     the system open() call.  If the modify time of an existing lock file is
+     more than PATIENCE seconds old, then the lock file is deleted and the
+     exclusive create is retried.
+   - Load the extra field from the foo.gz file, and see if an operation was in
+     progress but not completed.  If so, apply the recovery procedure below.
+   - Perform the append procedure with the provided data.
+   - If the uncompressed data in the foo.gz file is 1MB or more, apply the
+     compress procedure.
+   - Delete the foo.lock file.
+
+   Append procedure:
+   - Put what to append in the foo.add file so that the operation can be
+     restarted if this procedure is interrupted.
+   - Mark the foo.gz extra field with the append operation in progress.
+   + Restore the original last-block bit and stored block length of the last
+     stored block from the information in the extra field, in case a previous
+     append operation was interrupted.
+   - Append the provided data to the last stored block, creating new stored
+     blocks as needed and updating the stored blocks last-block bits and
+     lengths.
+   - Update the crc and length with the new data, and write the gzip trailer.
+   - Write over the extra field (with a single write operation) with the new
+     pointers, lengths, and crc's, and mark the gzip file as not in process.
+     Though there is still a foo.add file, it will be ignored since nothing
+     is in process.  If a foo.add file is leftover from a previously
+     completed operation, it is truncated when writing new data to it.
+   - Delete the foo.add file.
+
+   Compress and replace procedures:
+   - Read all of the uncompressed data in the stored blocks in foo.gz and write
+     it to foo.add.  Also write foo.temp with the last 32K of that data to
+     provide a dictionary for the next invocation of this procedure.
+   - Rewrite the extra field marking foo.gz with a compression in process.
+   * If there is no data provided to compress (due to a missing foo.add file
+     when recovering), reconstruct and truncate the foo.gz file to contain
+     only the previous compressed data and proceed to the step after the next
+     one.  Otherwise ...
+   - Compress the data with the dictionary in foo.dict, and write to the
+     foo.gz file starting at the bit immediately following the last previously
+     compressed block.  If there is no foo.dict, proceed anyway with the
+     compression at slightly reduced efficiency.  (For the foo.dict file to be
+     missing requires some external failure beyond simply the interruption of
+     a compress operation.)  During this process, the foo.lock file is
+     periodically touched to assure that that file is not considered stale by
+     another process before we're done.  The deflation is terminated with a
+     non-last empty static block (10 bits long), that is then located and
+     written over by a last-bit-set empty stored block.
+   - Append the crc and length of the data in the gzip file (previously
+     calculated during the append operations).
+   - Write over the extra field with the updated stored block offsets, bits
+     back, crc's, and lengths, and mark foo.gz as in process for a replacement
+     of the dictionary.
+   @ Delete the foo.add file.
+   - Replace foo.dict with foo.temp.
+   - Write over the extra field, marking foo.gz as complete.
+
+   Recovery procedure:
+   - If not a replace recovery, read in the foo.add file, and provide that data
+     to the appropriate recovery below.  If there is no foo.add file, provide
+     a zero data length to the recovery.  In that case, the append recovery
+     restores the foo.gz to the previous compressed + uncompressed data state.
+     For the the compress recovery, a missing foo.add file results in foo.gz
+     being restored to the previous compressed-only data state.
+   - Append recovery:
+     - Pick up append at + step above
+   - Compress recovery:
+     - Pick up compress at * step above
+   - Replace recovery:
+     - Pick up compress at @ step above
+   - Log the repair with a date stamp in foo.repairs

-<a name="Introduction"><h2> Introduction </h2>
-     The 'zlib' compression library provides in-memory compression and
-  decompression functions, including integrity checks of the uncompressed
-  data.  This version of the library supports only one compression method
-  (deflation) but other algorithms will be added later and will have the same
-  stream interface.
-  <p>
-
-     Compression can be done in a single step if the buffers are large
-  enough (for example if an input file is mmap'ed), or can be done by
-  repeated calls of the compression function.  In the latter case, the
-  application must provide more input and/or consume the output
-  (providing more output space) before each call.
-  <p>
-
-     The library also supports reading and writing files in gzip (.gz) format
-  with an interface similar to that of stdio.
-  <p>
-
-     The library does not install any signal handler. The decoder checks
-  the consistency of the compressed data, so the library should never
-  crash even in case of corrupted input.
-  <p>
-
-<hr>
-<a name="Utility functions"><h2> Utility functions </h2>
-     The following utility functions are implemented on top of the
-   <a href="#Basic functions">basic stream-oriented functions</a>.
-   To simplify the interface, some
-   default options are assumed (compression level and memory usage,
-   standard memory allocation functions). The source code of these
-   utility functions can easily be modified if you need special options.

-<dd>
-     Compresses the source buffer into the destination buffer.  sourceLen is
-   the byte length of the source buffer. Upon entry, destLen is the total

-   compressed buffer.<p>
-     This function can be used to <a href="#compress">compress</a> a whole file at once if the

-<font color="Blue"><dt> int  <a name="compress2">compress2</a> (Bytef *dest,   uLongf *destLen, const Bytef *source, uLong sourceLen, int level);</font>
-<dd>
-     Compresses the source buffer into the destination buffer. The level
-   parameter has the same meaning as in <a href="#deflateInit">deflateInit</a>.  sourceLen is the byte
-   length of the source buffer. Upon entry, destLen is the total size of the
-   destination buffer, which must be at least 0.1% larger than sourceLen plus
-   12 bytes. Upon exit, destLen is the actual size of the compressed buffer.
-   <p>
-
-     <a href="#compress2">compress2</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not enough

-   <p>
-
-<font color="Blue"><dt> int  <a name="uncompress">uncompress</a> (Bytef *dest,   uLongf *destLen, const Bytef *source, uLong sourceLen);</font>
-<dd>
-     Decompresses the source buffer into the destination buffer.  sourceLen is
-   the byte length of the source buffer. Upon entry, destLen is the total
-   size of the destination buffer, which must be large enough to hold the
-   entire uncompressed data. (The size of the uncompressed data must have
-   been saved previously by the compressor and transmitted to the decompressor
-   by some mechanism outside the scope of this compression library.)
-   Upon exit, destLen is the actual size of the compressed buffer. <p>
-     This function can be used to decompress a whole file at once if the
-   input file is mmap'ed.
-   <p>
-
-     <a href="#uncompress">uncompress</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not
-   enough memory, <a href="#Z_BUF_ERROR">Z_BUF_ERROR</a> if there was not enough room in the output

-<dd> <p>
-
-<font color="Blue"><dt>  gzFile  <a name="gzopen">gzopen</a>  (const char *path, const char *mode);</font>
-<dd>
-     Opens a gzip (.gz) file for reading or writing. The mode parameter
-   is as in fopen ("rb" or "wb") but can also include a compression level
-   ("wb9") or a strategy: 'f' for filtered data as in "wb6f", 'h' for
-   Huffman only compression as in "wb1h". (See the description
-   of <a href="#deflateInit2">deflateInit2</a> for more information about the strategy parameter.)
-   <p>
-
-     <a href="#gzopen">gzopen</a> can be used to read a file which is not in gzip format ; in this
-   case <a href="#gzread">gzread</a> will directly read from the file without decompression.
-   <p>
-
-     <a href="#gzopen">gzopen</a> returns NULL if the file could not be opened or if there was
-   insufficient memory to allocate the (de)compression <a href="#state">state</a> ; errno
-   can be checked to distinguish the two cases (if errno is zero, the
-   zlib error is <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a>).
-   <p>
-
-<font color="Blue"><dt> gzFile  <a name="gzdopen">gzdopen</a>  (int fd, const char *mode);</font>
-<dd>
-     <a href="#gzdopen">gzdopen</a>() associates a gzFile with the file descriptor fd.  File
-   descriptors are obtained from calls like open, dup, creat, pipe or
-   fileno (in the file has been previously opened with fopen).
-   The mode parameter is as in <a href="#gzopen">gzopen</a>.
-   <p>
-     The next call of <a href="#gzclose">gzclose</a> on the returned gzFile will also close the
-   file descriptor fd, just like fclose(fdopen(fd), mode) closes the file
-   descriptor fd. If you want to keep fd open, use <a href="#gzdopen">gzdopen</a>(dup(fd), mode).
-   <p>
-     <a href="#gzdopen">gzdopen</a> returns NULL if there was insufficient memory to allocate
-   the (de)compression <a href="#state">state</a>.
-   <p>
-
-<font color="Blue"><dt> int  <a name="gzsetparams">gzsetparams</a> (gzFile file, int level, int strategy);</font>
-<dd>
-     Dynamically update the compression level or strategy. See the description
-   of <a href="#deflateInit2">deflateInit2</a> for the meaning of these parameters.
-   <p>
-     <a href="#gzsetparams">gzsetparams</a> returns <a href="#Z_OK">Z_OK</a> if success, or <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the file was not
-   opened for writing.
-   <p>
-
-<font color="Blue"><dt> int     <a name="gzread">gzread</a>  (gzFile file, voidp buf, unsigned len);</font>
-<dd>
-     Reads the given number of uncompressed bytes from the compressed file.
-   If the input file was not in gzip format, <a href="#gzread">gzread</a> copies the given number

-<font color="Blue"><dt> int  <a name="deflateInit">deflateInit</a> (<a href="#z_streamp">z_streamp</a> strm, int level);</font>
-<dd>
-     Initializes the internal stream <a href="#state">state</a> for compression. The fields
-   <a href="#zalloc">zalloc</a>, <a href="#zfree">zfree</a> and <a href="#opaque">opaque</a> must be initialized before by the caller.
-   If <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a> are set to <a href="#Z_NULL">Z_NULL</a>, <a href="#deflateInit">deflateInit</a> updates them to

-
-<font color="Blue"><dt>  int  <a name="deflate">deflate</a> (<a href="#z_streamp">z_streamp</a> strm, int flush);</font>
-<dd>
-    <a href="#deflate">deflate</a> compresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full. It may introduce some
-  output latency (reading input without producing any output) except when
-  forced to flush.<p>
-
-    The detailed semantics are as follows. <a href="#deflate">deflate</a> performs one or both of the
-  following actions:
-
-  <ul>
-  <li> Compress more input starting at <a href="#next_in">next_in</a> and update <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a>
-    accordingly. If not all input can be processed (because there is not
-    enough room in the output buffer), <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a> are updated and
-    processing will resume at this point for the next call of <a href="#deflate">deflate</a>().
-
-  <li>
-    Provide more output starting at <a href="#next_out">next_out</a> and update <a href="#next_out">next_out</a> and <a href="#avail_out">avail_out</a>
-    accordingly. This action is forced if the parameter flush is non zero.
-    Forcing flush frequently degrades the compression ratio, so this parameter
-    should be set only when necessary (in interactive applications).
-    Some output may be provided even if flush is not set.
-  </ul> <p>
-
-  Before the call of <a href="#deflate">deflate</a>(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming
-  more output, and updating <a href="#avail_in">avail_in</a> or <a href="#avail_out">avail_out</a> accordingly ; <a href="#avail_out">avail_out</a>
-  should never be zero before the call. The application can consume the
-  compressed output when it wants, for example when the output buffer is full
-  (<a href="#avail_out">avail_out</a> == 0), or after each call of <a href="#deflate">deflate</a>(). If <a href="#deflate">deflate</a> returns <a href="#Z_OK">Z_OK</a>
-  and with zero <a href="#avail_out">avail_out</a>, it must be called again after making room in the
-  output buffer because there might be more output pending.
-  <p>
-
-    If the parameter flush is set to <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, all pending output is
-  flushed to the output buffer and the output is aligned on a byte boundary, so
-  that the decompressor can get all input data available so far. (In particular
-  <a href="#avail_in">avail_in</a> is zero after the call if enough output space has been provided
-  before the call.)  Flushing may degrade compression for some compression
-  algorithms and so it should be used only when necessary.
-  <p>
-
-    If flush is set to <a href="#Z_FULL_FLUSH">Z_FULL_FLUSH</a>, all output is flushed as with
-  <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, and the compression <a href="#state">state</a> is reset so that decompression can
-  restart from this point if previous compressed data has been damaged or if
-  random access is desired. Using <a href="#Z_FULL_FLUSH">Z_FULL_FLUSH</a> too often can seriously degrade
-  the compression.
-  <p>
-
-    If <a href="#deflate">deflate</a> returns with <a href="#avail_out">avail_out</a> == 0, this function must be called again
-  with the same value of the flush parameter and more output space (updated
-  <a href="#avail_out">avail_out</a>), until the flush is complete (<a href="#deflate">deflate</a> returns with non-zero
-  <a href="#avail_out">avail_out</a>).
-  <p>
-
-    If the parameter flush is set to <a href="#Z_FINISH">Z_FINISH</a>, pending input is processed,
-  pending output is flushed and <a href="#deflate">deflate</a> returns with <a href="#Z_STREAM_END">Z_STREAM_END</a> if there
-  was enough output space ; if <a href="#deflate">deflate</a> returns with <a href="#Z_OK">Z_OK</a>, this function must be
-  called again with <a href="#Z_FINISH">Z_FINISH</a> and more output space (updated <a href="#avail_out">avail_out</a>) but no
-  more input data, until it returns with <a href="#Z_STREAM_END">Z_STREAM_END</a> or an error. After
-  <a href="#deflate">deflate</a> has returned <a href="#Z_STREAM_END">Z_STREAM_END</a>, the only possible operations on the
-  stream are <a href="#deflateReset">deflateReset</a> or <a href="#deflateEnd">deflateEnd</a>.
-  <p>
-
-    <a href="#Z_FINISH">Z_FINISH</a> can be used immediately after <a href="#deflateInit">deflateInit</a> if all the compression
-  is to be done in a single step. In this case, <a href="#avail_out">avail_out</a> must be at least
-  0.1% larger than <a href="#avail_in">avail_in</a> plus 12 bytes.  If <a href="#deflate">deflate</a> does not return
-  <a href="#Z_STREAM_END">Z_STREAM_END</a>, then it must be called again as described above.
-  <p>
-
-    <a href="#deflate">deflate</a>() sets strm-&gt <a href="#adler">adler</a> to the <a href="#adler32">adler32</a> checksum of all input read
-  so far (that is, <a href="#total_in">total_in</a> bytes).
-  <p>
-
-    <a href="#deflate">deflate</a>() may update <a href="#data_type">data_type</a> if it can make a good guess about
-  the input data type (<a href="#Z_ASCII">Z_ASCII</a> or <a href="#Z_BINARY">Z_BINARY</a>). In doubt, the data is considered
-  binary. This field is only for information purposes and does not affect
-  the compression algorithm in any manner.
-  <p>
-
-    <a href="#deflate">deflate</a>() returns <a href="#Z_OK">Z_OK</a> if some progress has been made (more input
-  processed or more output produced), <a href="#Z_STREAM_END">Z_STREAM_END</a> if all input has been

-  <p>
-
-  The detailed semantics are as follows. <a href="#inflate">inflate</a> performs one or both of the

-
-  <ul>
-  <li> Decompress more input starting at <a href="#next_in">next_in</a> and update <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a>

-    until there is no more input data or no more space in the output buffer
-    (see below about the flush parameter).
-  </ul> <p>
-
-  Before the call of <a href="#inflate">inflate</a>(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming
-  more output, and updating the next_* and avail_* values accordingly.
-  The application can consume the uncompressed output when it wants, for
-  example when the output buffer is full (<a href="#avail_out">avail_out</a> == 0), or after each
-  call of <a href="#inflate">inflate</a>(). If <a href="#inflate">inflate</a> returns <a href="#Z_OK">Z_OK</a> and with zero <a href="#avail_out">avail_out</a>, it

-
-    If the parameter flush is set to <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, <a href="#inflate">inflate</a> flushes as much

-  not specified for values of the flush parameter other than <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>
-  and <a href="#Z_FINISH">Z_FINISH</a>, but the current implementation actually flushes as much output
-  as possible anyway.
-  <p>
-
-    <a href="#inflate">inflate</a>() should normally be called until it returns <a href="#Z_STREAM_END">Z_STREAM_END</a> or an
-  error. However if all decompression is to be performed in a single step
-  (a single call of <a href="#inflate">inflate</a>), the parameter flush should be set to
-  <a href="#Z_FINISH">Z_FINISH</a>. In this case all pending input is processed and all pending
-  output is flushed ; <a href="#avail_out">avail_out</a> must be large enough to hold all the
-  uncompressed data. (The size of the uncompressed data may have been saved
-  by the compressor for this purpose.) The next operation on this stream must
-  be <a href="#inflateEnd">inflateEnd</a> to deallocate the decompression <a href="#state">state</a>. The use of <a href="#Z_FINISH">Z_FINISH</a>
-  is never required, but can be used to inform <a href="#inflate">inflate</a> that a faster routine
-  may be used for the single <a href="#inflate">inflate</a>() call.
-  <p>
-
-     If a preset dictionary is needed at this point (see <a href="#inflateSetDictionary">inflateSetDictionary</a>
-  below), <a href="#inflate">inflate</a> sets strm-<a href="#adler">adler</a> to the <a href="#adler32">adler32</a> checksum of the

-  it sets strm-&gt <a href="#adler">adler</a> to the <a href="#adler32">adler32</a> checksum of all output produced
-  so far (that is, <a href="#total_out">total_out</a> bytes) and returns <a href="#Z_OK">Z_OK</a>, <a href="#Z_STREAM_END">Z_STREAM_END</a> or
-  an error code as described below. At the end of the stream, <a href="#inflate">inflate</a>()
-  checks that its computed <a href="#adler32">adler32</a> checksum is equal to that saved by the

-  <p>

-<font color="Blue"><dt>  int  <a name="deflateInit2">deflateInit2</a> (<a href="#z_streamp">z_streamp</a> strm, int  level, int  method, int  windowBits, int  memLevel, int  strategy);</font>
-
-<dd> This is another version of <a href="#deflateInit">deflateInit</a> with more compression options. The
-   fields <a href="#next_in">next_in</a>, <a href="#zalloc">zalloc</a>, <a href="#zfree">zfree</a> and <a href="#opaque">opaque</a> must be initialized before by
-   the caller.<p>
-
-     The method parameter is the compression method. It must be <a href="#Z_DEFLATED">Z_DEFLATED</a> in
-   this version of the library.<p>
-
-     The windowBits parameter is the base two logarithm of the window size
-   (the size of the history buffer).  It should be in the range 8..15 for this
-   version of the library. Larger values of this parameter result in better
-   compression at the expense of memory usage. The default value is 15 if
-   <a href="#deflateInit">deflateInit</a> is used instead.<p>
-
-     The memLevel parameter specifies how much memory should be allocated
-   for the internal compression <a href="#state">state</a>. memLevel=1 uses minimum memory but
-   is slow and reduces compression ratio ; memLevel=9 uses maximum memory
-   for optimal speed. The default value is 8. See zconf.h for total memory
-   usage as a function of windowBits and memLevel.<p>
-
-     The strategy parameter is used to tune the compression algorithm. Use the
-   value <a href="#Z_DEFAULT_STRATEGY">Z_DEFAULT_STRATEGY</a> for normal data, <a href="#Z_FILTERED">Z_FILTERED</a> for data produced by a
-   filter (or predictor), or <a href="#Z_HUFFMAN_ONLY">Z_HUFFMAN_ONLY</a> to force Huffman encoding only (no
-   string match).  Filtered data consists mostly of small values with a
-   somewhat random distribution. In this case, the compression algorithm is
-   tuned to <a href="#compress">compress</a> them better. The effect of <a href="#Z_FILTERED">Z_FILTERED</a> is to force more
-   Huffman coding and less string matching ; it is somewhat intermediate
-   between Z_DEFAULT and <a href="#Z_HUFFMAN_ONLY">Z_HUFFMAN_ONLY</a>. The strategy parameter only affects
-   the compression ratio but not the correctness of the compressed output even
-   if it is not set appropriately.<p>
-
-      <a href="#deflateInit2">deflateInit2</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not enough
-   memory, <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if a parameter is invalid (such as an invalid
-   method). <a href="#msg">msg</a> is set to null if there is no error message.  <a href="#deflateInit2">deflateInit2</a> does
-   not perform any compression: this will be done by <a href="#deflate">deflate</a>().<p>
-
-<font color="Blue"><dt> int  <a name="deflateSetDictionary">deflateSetDictionary</a> (<a href="#z_streamp">z_streamp</a> strm, const Bytef *dictionary, uInt  dictLength);</font>
-<dd>
-     Initializes the compression dictionary from the given byte sequence
-   without producing any compressed output. This function must be called
-   immediately after <a href="#deflateInit">deflateInit</a>, <a href="#deflateInit2">deflateInit2</a> or <a href="#deflateReset">deflateReset</a>, before any
-   call of <a href="#deflate">deflate</a>. The compressor and decompressor must use exactly the same
-   dictionary (see <a href="#inflateSetDictionary">inflateSetDictionary</a>).<p>
-
-     The dictionary should consist of strings (byte sequences) that are likely
-   to be encountered later in the data to be compressed, with the most commonly
-   used strings preferably put towards the end of the dictionary. Using a
-   dictionary is most useful when the data to be compressed is short and can be
-   predicted with good accuracy ; the data can then be compressed better than
-   with the default empty dictionary.<p>
-
-     Depending on the size of the compression data structures selected by
-   <a href="#deflateInit">deflateInit</a> or <a href="#deflateInit2">deflateInit2</a>, a part of the dictionary may in effect be
-   discarded, for example if the dictionary is larger than the window size in
-   <a href="#deflate">deflate</a> or deflate2. Thus the strings most likely to be useful should be
-   put at the end of the dictionary, not at the front.<p>
-
-     Upon return of this function, strm-&gt <a href="#adler">adler</a> is set to the Adler32 value
-   of the dictionary ; the decompressor may later use this value to determine
-   which dictionary has been used by the compressor. (The Adler32 value
-   applies to the whole dictionary even if only a subset of the dictionary is
-   actually used by the compressor.)<p>
-
-     <a href="#deflateSetDictionary">deflateSetDictionary</a> returns <a href="#Z_OK">Z_OK</a> if success, or <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if a
-   parameter is invalid (such as NULL dictionary) or the stream <a href="#state">state</a> is
-   inconsistent (for example if <a href="#deflate">deflate</a> has already been called for this stream
-   or if the compression method is bsort). <a href="#deflateSetDictionary">deflateSetDictionary</a> does not
-   perform any compression: this will be done by <a href="#deflate">deflate</a>().<p>

-<dd>
-     Sets the destination stream as a complete copy of the source stream.<p>
-
-     This function can be useful when several compression strategies will be
-   tried, for example when there are several ways of pre-processing the input
-   data with a filter. The streams that will be discarded should then be freed
-   by calling <a href="#deflateEnd">deflateEnd</a>.  Note that <a href="#deflateCopy">deflateCopy</a> duplicates the internal
-   compression <a href="#state">state</a> which can be quite large, so this strategy is slow and
-   can consume lots of memory.<p>
-
-     <a href="#deflateCopy">deflateCopy</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not

-   but does not free and reallocate all the internal compression <a href="#state">state</a>.
-   The stream will keep the same compression level and any other attributes
-   that may have been set by <a href="#deflateInit2">deflateInit2</a>.<p>
-
-      <a href="#deflateReset">deflateReset</a> returns <a href="#Z_OK">Z_OK</a> if success, or <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the source
-   stream <a href="#state">state</a> was inconsistent (such as <a href="#zalloc">zalloc</a> or <a href="#state">state</a> being NULL).<p>
-
-<font color="Blue"><dt> int  <a name="deflateParams">deflateParams</a> (<a href="#z_streamp">z_streamp</a> strm, int level, int strategy);</font>
-<dd>
-     Dynamically update the compression level and compression strategy.  The
-   interpretation of level and strategy is as in <a href="#deflateInit2">deflateInit2</a>.  This can be
-   used to switch between compression and straight copy of the input data, or
-   to switch to a different kind of input data requiring a different
-   strategy. If the compression level is changed, the input available so far
-   is compressed with the old level (and may be flushed); the new level will
-   take effect only at the next call of <a href="#deflate">deflate</a>().<p>
-
-     Before the call of <a href="#deflateParams">deflateParams</a>, the stream <a href="#state">state</a> must be set as for
-   a call of <a href="#deflate">deflate</a>(), since the currently available input may have to
-   be compressed and flushed. In particular, strm-&gt <a href="#avail_out">avail_out</a> must be
-   non-zero.<p>
-
-     <a href="#deflateParams">deflateParams</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the source
-   stream <a href="#state">state</a> was inconsistent or if a parameter was invalid, <a href="#Z_BUF_ERROR">Z_BUF_ERROR</a>

-   before by the caller.<p>
-
-     The windowBits parameter is the base two logarithm of the maximum window
-   size (the size of the history buffer).  It should be in the range 8..15 for
-   this version of the library. The default value is 15 if <a href="#inflateInit">inflateInit</a> is used
-   instead. If a compressed stream with a larger window size is given as
-   input, <a href="#inflate">inflate</a>() will return with the error code <a href="#Z_DATA_ERROR">Z_DATA_ERROR</a> instead of
-   trying to allocate a larger window.<p>
-
-      <a href="#inflateInit2">inflateInit2</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not enough

-   does not perform any decompression apart from reading the zlib header if

-This directory contains project files for building zlib under various
-Integrated Development Environments (IDE).
-
-If you wish to submit a new project to this directory, you should comply
-to the following requirements.  Otherwise (e.g. if you wish to integrate
-a custom piece of code that changes the zlib interface or its behavior),
-please consider submitting the project to the contrib directory.
-
-
-Requirements
-============
-
-- The project must build zlib using the source files from the official
-  zlib source distribution, exclusively.
-
-- If the project produces redistributable builds (e.g. shared objects
-  or DLL files), these builds must be compatible to those produced by
-  makefiles, if such makefiles exist in the zlib distribution.
-  In particular, if the project produces a DLL build for the Win32
-  platform, this build must comply to the officially-ammended Win32 DLL
-  Application Binary Interface (ABI), described in win32/DLL_FAQ.txt.
-
-- The project may provide additional build targets, which depend on
-  3rd-party (unofficially-supported) software, present in the contrib
-  directory.  For example, it is possible to provide an "ASM build",
-  besides the officially-supported build, and have ASM source files
-  among its dependencies.
-
-- If there are significant differences between the project files created
-  by different versions of an IDE (e.g. Visual C++ 6.0 vs. 7.0), the name
-  of the project directory should contain the version number of the IDE
-  for which the project is intended (e.g. "visualc6" for Visual C++ 6.0,
-  or "visualc7" for Visual C++ 7.0 and 7.1).
-

-This project builds the zlib binaries as follows:
-
-* Win32_DLL_Release\zlib1.dll       DLL build
-* Win32_DLL_Debug\zlib1d.dll        DLL build (debug version)
-* Win32_DLL_ASM_Release\zlib1.dll   DLL build using ASM code
-* Win32_DLL_ASM_Debug\zlib1d.dll    DLL build using ASM code (debug version)
-* Win32_LIB_Release\zlib.lib        static build
-* Win32_LIB_Debug\zlibd.lib         static build (debug version)
-* Win32_LIB_ASM_Release\zlib.lib    static build using ASM code
-* Win32_LIB_ASM_Debug\zlibd.lib     static build using ASM code (debug version)
-
-
-For more information regarding the DLL builds, please see the DLL FAQ
-in ..\..\win32\DLL_FAQ.txt.
-
-
-To build and test:
-
-1) On the main menu, select "File | Open Workspace".
-   Open "zlib.dsw".
-
-2) Select "Build | Set Active Configuration".
-   Choose the configuration you wish to build.
-
-3) Select "Build | Clean".
-
-4) Select "Build | Build ... (F7)".  Ignore warning messages about
-   not being able to find certain include files (e.g. alloc.h).
-
-5) If you built one of the sample programs (example or minigzip),
-   select "Build | Execute ... (Ctrl+F5)".
-
-
-To use:
-
-1) Select "Project | Settings (Alt+F7)".
-   Make note of the configuration names used in your project.
-   Usually, these names are "Win32 Release" and "Win32 Debug".
-
-2) In the Workspace window, select the "FileView" tab.
-   Right-click on the root item "Workspace '...'".
-   Select "Insert Project into Workspace".
-   Switch on the checkbox "Dependency of:", and select the name
-   of your project.  Open "zlib.dsp".
-
-3) Select "Build | Configurations".
-   For each configuration of your project:
-   3.1) Choose the zlib configuration you wish to use.
-   3.2) Click on "Add".
-   3.3) Set the new zlib configuration name to the name used by
-        the configuration from the current iteration.
-
-4) Select "Build | Set Active Configuration".
-   Choose the configuration you wish to build.
-
-5) Select "Build | Build ... (F7)".
-
-6) If you built an executable program, select
-   "Build | Execute ... (Ctrl+F5)".
-
-
-Note:
-
-To build the ASM-enabled code, you need Microsoft Assembler
-(ML.EXE).  You can get it by downloading and installing the
-latest Processor Pack for Visual C++ 6.0.

+/* -- memory tracking routines -- */
+
+/*
+   These memory tracking routines are provided to zlib and track all of zlib's
+   allocations and deallocations, check for LIFO operations, keep a current
+   and high water mark of total bytes requested, optionally set a limit on the
+   total memory that can be allocated, and when done check for memory leaks.
+
+   They are used as follows:
+
+   z_stream strm;
+   mem_setup(&strm)         initializes the memory tracking and sets the
+                            zalloc, zfree, and opaque members of strm to use
+                            memory tracking for all zlib operations on strm
+   mem_limit(&strm, limit)  sets a limit on the total bytes requested -- a
+                            request that exceeds this limit will result in an
+                            allocation failure (returns NULL) -- setting the
+                            limit to zero means no limit, which is the default
+                            after mem_setup()
+   mem_used(&strm, "msg")   prints to stderr "msg" and the total bytes used
+   mem_high(&strm, "msg")   prints to stderr "msg" and the high water mark
+   mem_done(&strm, "msg")   ends memory tracking, releases all allocations
+                            for the tracking as well as leaked zlib blocks, if
+                            any.  If there was anything unusual, such as leaked
+                            blocks, non-FIFO frees, or frees of addresses not
+                            allocated, then "msg" and information about the
+                            problem is printed to stderr.  If everything is
+                            normal, nothing is printed. mem_done resets the
+                            strm members to Z_NULL to use the default memory
+                            allocation routines on the next zlib initialization
+                            using strm.

+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.8 is a general purpose data compression library.  All the code is
+thread safe.  The data format used by the zlib library is described by RFCs
+(Request for Comments) 1950 to 1952 in the files
+http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
+and rfc1952.txt (gzip format).
+
+All functions of the compression library are documented in the file zlib.h
+(volunteer to write man pages welcome, contact zlib@gzip.org).  Two compiled
+examples are distributed in this package, example and minigzip.  The example_d
+and minigzip_d flavors validate that the zlib1.dll file is working correctly.
+
+Questions about zlib should be sent to <zlib@gzip.org>.  The zlib home page
+is http://zlib.net/ .  Before reporting a problem, please check this site to
+verify that you have the latest version of zlib; otherwise get the latest
+version and check whether the problem still exists or not.
+
+PLEASE read DLL_FAQ.txt, and the the zlib FAQ http://zlib.net/zlib_faq.html
+before asking for help.
+
+
+Manifest:
+
+The package zlib-1.2.8-win32-x86.zip will contain the following files:
+
+  README-WIN32.txt This document
+  ChangeLog        Changes since previous zlib packages
+  DLL_FAQ.txt      Frequently asked questions about zlib1.dll
+  zlib.3.pdf       Documentation of this library in Adobe Acrobat format
+
+  example.exe      A statically-bound example (using zlib.lib, not the dll)
+  example.pdb      Symbolic information for debugging example.exe
+
+  example_d.exe    A zlib1.dll bound example (using zdll.lib)
+  example_d.pdb    Symbolic information for debugging example_d.exe
+
+  minigzip.exe     A statically-bound test program (using zlib.lib, not the dll)
+  minigzip.pdb     Symbolic information for debugging minigzip.exe
+
+  minigzip_d.exe   A zlib1.dll bound test program (using zdll.lib)
+  minigzip_d.pdb   Symbolic information for debugging minigzip_d.exe
+
+  zlib.h           Install these files into the compilers' INCLUDE path to
+  zconf.h          compile programs which use zlib.lib or zdll.lib
+
+  zdll.lib         Install these files into the compilers' LIB path if linking
+  zdll.exp         a compiled program to the zlib1.dll binary
+
+  zlib.lib         Install these files into the compilers' LIB path to link zlib
+  zlib.pdb         into compiled programs, without zlib1.dll runtime dependency
+                   (zlib.pdb provides debugging info to the compile time linker)
+
+  zlib1.dll        Install this binary shared library into the system PATH, or
+                   the program's runtime directory (where the .exe resides)
+  zlib1.pdb        Install in the same directory as zlib1.dll, in order to debug
+                   an application crash using WinDbg or similar tools.
+
+All .pdb files above are entirely optional, but are very useful to a developer
+attempting to diagnose program misbehavior or a crash.  Many additional
+important files for developers can be found in the zlib127.zip source package
+available from http://zlib.net/ - review that package's README file for details.
+
+
+Acknowledgments:
+
+The deflate format used by zlib was defined by Phil Katz.  The deflate and
+zlib specifications were written by L.  Peter Deutsch.  Thanks to all the
+people who reported problems and suggested various improvements in zlib; they
+are too numerous to cite here.

+
+Installing ZLIB1.DLL
+====================
+  Copy ZLIB1.DLL to the SYSTEM or the SYSTEM32 directory.
+
+
+Using ZLIB1.DLL with Microsoft Visual C++
+=========================================
+   1. Install the supplied header files "zlib.h" and "zconf.h"
+      into a directory found in the INCLUDE path list.
+
+   2. Install the supplied library file "zdll.lib" into a
+      directory found in the LIB path list.
+
+   3. Add "zdll.lib" to your project.
+
+
+Using ZLIB1.DLL with gcc/MinGW
+==============================
+   1. Install the supplied header files "zlib.h" and "zconf.h"
+      into the INCLUDE directory.
+
+   2. Copy the supplied library file "zdll.lib" to "libzdll.a":
+        cp lib/zdll.lib lib/libzdll.a
+
+      OR
+
+   2' Build the import library from the supplied "zlib.def":
+        dlltool -D zlib1.dll -d lib/zlib.def -l lib/libzdll.a
+
+   3. Install "libzdll.a" into the LIB directory.
+
+   4. Add "libzdll.a" to your project, or use the -lzdll option.
+
+
+Using ZLIB1.DLL with gcc/Cygwin
+===============================
+  ZLIB1.DLL is not designed to work with Cygwin.  The Cygwin
+  system has its own DLL build of zlib, named CYGZ.DLL.
+
+
+Using ZLIB1.DLL with Borland C++
+================================
+   1. Install the supplied header files "zlib.h" and "zconf.h"
+      into a directory found in the INCLUDE path list.
+
+   2. Build the import library using the IMPLIB tool:
+        implib -a -c -f lib\zdllbor.lib zlib1.dll
+
+      OR
+
+   2' Convert the supplied library file "zdll.lib" to OMF format,
+      using the COFF2OMF tool:
+        coff2omf lib\zdll.lib lib\zdllbor.lib
+
+   3. Install "zdllbor.lib" into a directory found in the LIB path
+      list.
+
+   4. Add "zdllbor.lib" to your project.
+
+  Notes:
+  - The modules that are linked with "zdllbor.lib" must be compiled
+    using a 4-byte alignment (option -a):
+        bcc32 -a -c myprog.c
+        bcc32 myprog.obj zdllbor.lib
+  - If you wish, you may use "zlib1.lib" instead of "zdllbor.lib".
+
+
+Rebuilding ZLIB1.DLL
+====================
+  Depending on your build environment, use the appropriate
+  makefile from the win32/ directory, found in the zlib source
+  distribution.
+
+  Your custom build has to comply with the requirements stated
+  in DLL_FAQ.txt, including (but not limited to) the following:
+    - It must be built from an unaltered zlib source distribution.
+    - It must be linked to MSVCRT.DLL.
+    - The macros that compile out certain portions of the zlib
+      code (such as NO_GZCOMPRESS, NO_GZIP) must not be enabled.
+    - The ZLIB_WINAPI macro must not be enabled.
+
+  Furthermore, it has to run successfully with the test suite
+  found in this package.
+
+  It is recommended, however, to use the supplied ZLIB1.DLL,
+  instead of rebuilding it yourself.  You should rebuild it
+  only if you have a special reason.

+.PP
+\fBTcl_LoadFile\fR loads a file from the filesystem (including potentially any
+virtual filesystem that has been installed) and provides a handle to it that
+may be used in further operations. The \fIsymbols\fR array, if non-NULL,
+supplies a set of names of symbols (typically functions) that must be resolved
+from the library and which will be stored in the array indicated by
+\fIprocPtrs\fR. If any of the symbols is not resolved, the loading of the file
+will fail with an error message left in the interpreter (if that is non-NULL).
+The result of \fBTcl_LoadFile\fR is a standard Tcl error code. The library may
+be unloaded with \fBTcl_FSUnloadFile\fR.
+.PP
+\fBTcl_FindSymbol\fR locates a symbol in a loaded library and returns it. If
+the symbol cannot be found, it returns NULL and sets an error message in the
+given \fIinterp\fR (if that is non-NULL). Note that it is unsafe to use this
+operation on a handle that has been passed to \fBTcl_FSUnloadFile\fR.

+parameter; the initial value to use for this can be obtained by using NULL for
+the \fIbytes\fR parameter instead of a pointer to the array of bytes to

 linked to a Tcl command, according to its arguments, and provides an abstract

 \fBTcl_ZlibStreamGetCommandName\fR returns the name of that command given the

+to be thread-safe; each stream should only ever be used from the thread that
+created it. When working with gzip streams, a dictionary (fields as given in
+the \fBGZIP OPTIONS DICTIONARY\fR section below) can be given via the
+\fIdictObj\fR parameter that on compression allows control over the generated
+headers, and on decompression allows discovery of the existing headers. Note
+that the dictionary will be written to on decompression once sufficient data
+has been read to have a complete header. This means that the dictionary must

+\fBTcl_NewObj\fR is suggested.
 .PP
 Once a stream has been constructed, \fBTcl_ZlibStreamPut\fR is used to add
 data to the stream and \fBTcl_ZlibStreamGet\fR is used to retrieve data from
-the stream after processing. Both return normal Tcl result codes. With

 .PP
+\fBTcl_ZlibStreamSetCompressionDictionary\fR is used to control the
+compression dictionary used with the stream, a compression dictionary being an
+array of bytes (such as might be created with \fBTcl_NewByteArrayObj\fR) that
+is used to initialize the compression engine rather than leaving it to create
+it on the fly from the data being compressed. Setting a compression dictionary
+allows for more efficient compression in the case where the start of the data
+is highly regular, but it does require both the compressor and the
+decompressor to agreee on the value to use. Compression dictionaries are only
+fully supported for zlib-format data; on compression, they must be set before
+any data is sent in with \fBTcl_ZlibStreamPut\fR, and on decompression they
+should be set when \fBTcl_ZlibStreamGet\fR produces an \fBerror\fR with its

+the compression dictionary sought. (Note that this is only true for
+zlib-format streams; gzip streams ignore compression dictionaries as the
+format specification doesn't permit them, and raw streams just produce a data
+error if the compression dictionary is missing or incorrect.)
+.PP
+If you wish to clear a stream and reuse it for a new compression or
+decompression action, \fBTcl_ZlibStreamReset\fR will do this and return a
+normal Tcl result code to indicate whether it was successful; if the stream is
+registered with an interpreter, an error message will be left in the
+interpreter result when this function returns TCL_ERROR.
 Finally, \fBTcl_ZlibStreamClose\fR will clean up the stream and delete the
