	* generic/tclBasic.c:   Fix for #3008307: make callerPtr chains
	* generic/tclExecute.c: be traversable accross coro
	boundaries. Add the special coroutine CallFrame (partially
	reverting commit of 2009-12-10), as it is needed for coroutines
	that do not push a CF - eg, those with [eval] as command. Thanks
	to Colin McCormack (coldstore) and Alexandre Ferrieux for the
	hard work on this.

2010-06-03  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>

	* generic/tclNamesp.c: Safer (and faster) computation of [uplevel]
	* tests/error.test:    offsets in TIP 348. Toplevel offsets no longer
	* tests/result.test:   overestimated.

	                   the radar on 2010-02-24 (dkf): EIAS violation in
	                   list-dict conversions.

2010-05-19  Jan Nijtmans  <nijtmans@users.sf.net>

	* generic/regcomp.c:     Don't use arrays of length 1, just use a
	* generic/tclFileName.c: single element then, it makes code more
	* generic/tclLoad.c:     readable. (Here it even prevents a type cast)

2010-04-30  Miguel Sofer  <msofer@users.sf.net>

	* tests/coroutine.test: testing coroutine arguments after [yield]:
	check that only 0/1 allowed

2010-04-30  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclBasic.c (NRInterpCoroutine): Corrected handling of

	* generic/tclBasic.c (TclNRYieldObjCmd, TclNRYieldmObjCmd)
	(NRInterpCoroutine): Replace magic values for formal argument counts
	for coroutine command implementations with #defines, for an increase
	in readability.

2010-04-30  Jan Nijtmans  <nijtmans@users.sf.net>

	* generic/tclMain.c: Unnecessary TCL_STORAGE_CLASS re-definition. It
	was used for an ancient dummy reference to Tcl_LinkVar(), but that's
	already gone since 2002-05-29.

2010-04-29  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompExpr.c: Slight change in the literal sharing

	* generic/tclBinary.c (TclAppendBytesToByteArray): [Bug 2992970]: Make
	* generic/tclStringObj.c (Tcl_AppendObjToObj): an append of a byte
	array to another into an efficent operation. The problem was the (lack
	of) a proper growth management strategy for the byte array.

2010-04-29  Jan Nijtmans  <nijtmans@users.sf.net>

	* compat/dirent2.h:	Include "tcl.h", not <tcl.h>, like everywhere
	* compat/dlfcn.h:	else, to ensure that the version in the Tcl
	* compat/stdlib.h:	distribution is used, not some version from
	* compat/string.h:	somewhere else.
	* compat/unistd.h:

2010-04-28  Jan Nijtmans  <nijtmans@users.sf.net>

	* win/Makefile.in:	Remove unused @MAN2TCLFLAGS@
	* win/tclWinPort.h:	Move <limits.h> include from tclInt.h to
	* generic/tclInt.h:	tclWinPort.h, and eliminate unneeded
	* generic/tclEnv.c:	<stdlib.h>, <stdio.h> and <string.h>, which
				are already in tclInt.h
	* generic/regcustom.h:	Move "tclInt.h" from regcustom.h up to
	* generic/regex.h:	regex.h.
	* generic/tclAlloc.c:	Unneeded <stdio.h> include.
	* generic/tclExecute.c:	Fix gcc warning: comparison between signed and
				unsigned.

2010-04-28  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclInt.h (TclIsVarDirectUnsettable): Corrected flags so that
	deletion of traces is not optimized out...

	* generic/tclExecute.c (ExecuteExtendedBinaryMathOp)
	(TclCompareTwoNumbers,ExecuteExtendedUnaryMathOp,TclExecuteByteCode):
	[Patch 2981677]: Move the less common arithmetic operations (i.e.,
	exponentiation and operations on non-longs) out of TEBC for a big drop
	in the overall size of the stack frame for most code. Net effect on
	speed is minimal (slightly faster overall in tclbench). Also extended
	the number of places where TRESULT handling is replaced with a jump to
	dedicated code.

2010-04-27  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclExecute.c (TclExecuteByteCode): Rearrange location of an

	* unix/tclLoadDl.c (FindSymbol): [Bug 2992295]: Simplified the logic
	so that the casts added in Donal Fellows's change for the same bug are
	no longer necessary.

2010-04-26  Donal K. Fellows  <dkf@users.sf.net>

	* unix/tclLoadDl.c (FindSymbol): [Bug 2992295]: Added an explicit cast
	because auto-casting between function and non-function types is never
	naturally warning-free.

	* generic/tclStubInit.c:   Add a small amount of gcc-isms (with #ifdef
	* generic/tclOOStubInit.c: guards) to ensure that warnings are issued
	when these files are older than the various *.decls files.

2010-04-25  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:    Add unsupported [yieldm] command. Credit
	* generic/tclInt.h:      Lars Hellstrom for the basic idea.

	* generic/tclInt.h:      mods to tailcall. Thanks kbk for detecting
	the problem.

2010-04-23  Jan Nijtmans  <nijtmans@users.sf.net>

	* unix/tclUnixPort.h: [Bug 2991415]: tclport.h #included before

2010-04-19  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclExecute.c (TclExecuteByteCode): Improve commenting and

	* doc/unset.n: [Bug 2988940]: Fix typo.

2010-04-15  Jan Nijtmans  <nijtmans@users.sf.net>

	* win/tclWinPort.h:       Move inclusion of <tchar.h> from
	* generic/tcl.h:          tclPlatDecls.h to tclWinPort.h, where it
	* generic/tclPlatDecls.h: belongs. Add fallback in tcl.h, so TCHAR is
				  available in win32 always.

2010-04-15  Donal K. Fellows  <dkf@users.sf.net>

	* doc/try.n: [Bug 2987551]: Fix typo.

2010-04-14  Andreas Kupries  <andreask@activestate.com>

	* library/platform/platform.tcl: Linux platform identification:
	* library/platform/pkgIndex.tcl: Check /lib64 for existence of files
	* unix/Makefile.in: matching libc* before accepting it as base
	* win/Makefile.in:  directory. This can happen on weirdly installed
	32bit systems which have an empty or partially filled /lib64 without
	an actual libc. Bumped to version 1.0.6.

2010-04-13  Jan Nijtmans  <nijtmans@users.sf.net>

	* win/tclWinPort.h: Fix [Patch 2986105]: conditionally defining

	* win/tclWinLoad.c: Fix gcc warning: comparison of unsigned expression
	>= 0 is always true

2010-04-08  Donal K. Fellows  <dkf@users.sf.net>

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

	TIP #362 IMPLEMENTATION

	* win/tclWinReg.c: [Patch 2960976]: Apply patch from Damon Courtney to
	* tests/registry.test:	allow the registry command to be told to work
	* win/Makefile.in:	with both 32-bit and 64-bit registries. Bump
	* win/configure.in:	version of registry package to 1.3.
	* win/makefile.bc:
	* win/makefile.vc:
	* win/configure:	autoconf-2.59

	* macosx/tclMacOSXBundle.c, macosx/tclMacOSXFCmd.c:
	* macosx/tclMacOSXNotify.c: Reduce the level of ifdeffery in the
	functions of these files to improve readability. They need to be
	audited for whether complexity can be removed based on the minimum

	* 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

ZLIB DATA COMPRESSION LIBRARY

zlib 1.2.5 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).  A usage example
of the library is given in the file example.c which also tests that the library
is working correctly.  Another example is given in the file minigzip.c.  The
compression library itself is composed of all source files except example.c and
minigzip.c.

To compile all files and run the test program, follow the instructions given at
the top of Makefile.in.  In short "./configure; make test", and if that goes
well, "make install" should work for most flavors of Unix.  For Windows, use one
of the special makefiles in win32/ or contrib/vstudio/ .  For VMS, use
make_vms.com.

Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
<info@winimage.com> for the Windows DLL version.  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 the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.

Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan.  1997
issue of Dr.  Dobb's Journal; a copy of the article is available at
http://marknelson.us/1997/01/01/zlib-engine/ .

The changes made in version 1.2.5 are documented in the file ChangeLog.

Unsupported third party contributions are provided in directory contrib/ .

zlib is available in Java using the java.util.zip package, documented at
http://java.sun.com/developer/technicalArticles/Programming/compression/ .

A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available

#    prefix=$HOME CC=cc CFLAGS="-O4" ./configure
# or for csh/tcsh users:
#    (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)

# Incorrect settings of CC or CFLAGS may prevent creating a shared library.
# If you have problems, try without defining CC and CFLAGS before reporting
# an error.

 * tables for updating the shift register in one step with three exclusive-ors

ZLIB DATA COMPRESSION LIBRARY

zlib 1.2.4 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-1.2.4-win32-x86.zip contains 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 zlib124.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.
