2002-06-05  Don Porter  <dgp@users.sourceforge.net>

	* win/makefile.vc:
	* win/rules.vc:  Added a new "loimpact" option that sets the
	-ws:aggressive linker option. Off by default. It's said to keep the
	heap use low at the expense of alloc speed.

	* win/tclAppInit.c: Changed #include "tcl.h" to be tclPort.h to remove
	the raw windows.h include. tclPort.h brings in windows.h already and
	lessens the pre-compiled-header mush and the randomly useless #pragma
	lessens the precompiled-header mush and the randomly useless #pragma
	comment (lib,...) references throughout the big windows.h tree (as
	observed at high linker warning levels).

2002-02-21  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tcl.h: Better guessing of LP64/ILP32 architecture, but now
	sensitive to presence of (suitable) <limits.h>

	* generic/tclCmdAH.c: 64-bit handling in [file] and [format]
	commands.
	* generic/tclBasic.c: New "wordSize" entry in ::tcl_platform.

	* generic/tclIO.c: Large-file support (with many consequences.)
	* compat/strtoll.c, compat/strtoull.c: New support functions.
	* unix/tcl.m4, unix/configure: 64-bit support and greatly enhanced

	Most other changes, including all those in doc/* and test/* as well as
	the majority in the platform directories, follow on from these.

	Also coming out of the woodwork:

	interesting situation with the precollected single-linked list of
	states to be splitted: many items were added to the list, but only
	several of them are accessible from the list beginning, since the

	the next list item) gets overwritten, which results in a "looped"
	chain. As a result, not all of states are splitted, and one state is
	splitted two times, causing incorrect "no-progress" flag values.

2004-07-16  Jeff Hobbs	<jeffh@ActiveState.com>

	* unix/Makefile.in, unix/tcl.m4:     move (C|LD)FLAGS after their

	* tests/winPipe.test: more pass-thru commandline verifications.
	* win/tclWinPipe.c (BuildCommandLine): Special case quoting for '{'
	not required by the c-runtimes's parse_cmdline().
	* win/tclAppInit.c: Removed our custom setargv() in favor of the work

	* generic/tclCompCmds.c: Rewrote TclCompileReturnCmd() to call
	TclMergeReturnOptions() at compile time so the return options
	dictionary is computed at compile time (when it is fully known). The
	dictionary is pushed on the stack along with the result, and the code
	and level values are included in the bytecode as operands. Also

	* generic/tclExecute.c: Rewrote INST_RETURN instruction to retrieve
	the code and level operands, pop the return options from the stack,
	and call TclProcessReturn() to perform the [return] operation.

	* generic/tclCompile.h:	New utilities include TclEmitInt4 macro

	since when the list of opcodes changes it is usually useful to rebuild
	everything that depends on it (but which is nonetheless a small
	fraction of the total set of Tcl source files).

	***POTENTIAL INCOMPATIBILITY*** for bytecode savers/loaders. See below

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Arrange for very simple

	[switch] invocations to be compiled into hash lookups into jump tables;
	only a very specific kind of [switch] can be safely compiled this way,
	but that happens to be the most common kind. This makes around 5-10%
	difference to the speed of execution of clock.test.
	* generic/tclExecute.c (TEBC:INST_JUMP_TABLE): New instruction to allow
	for jumps to locations looked up in a hashtable. Requires a new AuxData
	type, tclJumptableInfoType (supported by the functions DupJumptableInfo
	and FreeJumptableInfo in tclCompCmds.c) so anything that saves bytecode

	an expr syntax error (masked by a [catch]).

	* generic/tclCompCmds.c (TclCompileReturnCmd):	Added crash protection
	to handle callers other than TclCompileScript() failing to meet the
	initialization assumptions of the TIP 280 code in CompileWord().

	numeric when pre-compiling a constant expression indicates an error.

to implement the safe base, instead of deleting the commands from a safe
interpreter. (JL)

11/15/96 (new feature) Implemented the safe base, a mechanism for
installing and requesting security policies, purely in Tcl code. Overloads
the package command to also allow an interpreter to "require" a policy. The
following new library commands are provided:
	tcl_safeCreateInterp	-- creates a slave an initializes the
	tcl_safeCreateInterp	-- creates a slave and initializes the
				   policy mechanism.
	tcl_safeInitInterp	-- initializes an existing slave with the
				   policy mechanism.
	tcl_safeDeleteInterp	-- deletes a slave and deinitializes the
				   policy mechanism.
Added a new file to the library, safeinit.tcl, to hold implementation. (JL)
On 7/9/97, removed the policy loading mechanism from the Safe Base. Left

6/19/97 (bug fix) Fixed a panic due to the following four line script:
	interp create x
	x alias foo bar
	x eval rename foo blotz
	x alias foo {}
The problem was that the interp code was not using the actual current name
of the command to be deleted as a result of un-aliasing foo. (JL)
of the command to be deleted as a result of unaliasing foo. (JL)

6/19/97 (feature change) Pass interp down to the ChannelOption and
driver specific calls so system errors can be differentiated from syntax
ones. Changed Tcl_DriverGetOptionProc type. Affects Tcl_GetChannelOption,
TcpGetOptionProc,  TtyGetOptionProc, etc. (DL)

 ****************************************************************************
 *
 *  Version 0.1.16.0
 *
 *  The ANSI C standard committee, for the C99 standard, specified the
 *  inclusion of a new standard include file called stdint.h.  This is
 *  a very useful and long desired include file which contains several
 *  very precise definitions for integer scalar types that is critically
 *  important for making several classes of applications portable
 *  including cryptography, hashing, variable length integer libraries
 *  and so on.  But for most developers its likely useful just for
 *  programming sanity.
 *
 *  The problem is that some compiler vendors chose to ignore the C99
 *  standard and some older compilers have no opportunity to be updated.
 *  Because of this situation, simply including stdint.h in your code
 *  makes it unportable.
 *
 *  So that's what this file is all about.  It's an attempt to build a
 *  single universal include file that works on as many platforms as
 *  possible to deliver what stdint.h is supposed to.  Even compilers
 *  that already come with stdint.h can use this file instead without
 *  any loss of functionality.  A few things that should be noted about
 *  this file:
 *
 *    1) It is not guaranteed to be portable and/or present an identical
 *       interface on all platforms.  The extreme variability of the
 *       ANSI C standard makes this an impossibility right from the
 *       very get go. Its really only meant to be useful for the vast
 *       majority of platforms that possess the capability of
 *       implementing usefully and precisely defined, standard sized
 *       integer scalars.  Systems which are not intrinsically 2s
 *       complement may produce invalid constants.
 *
 *    2) There is an unavoidable use of non-reserved symbols.
 *
 *    3) Other standard include files are invoked.
 *
 *    4) This file may come in conflict with future platforms that do
 *       include stdint.h.  The hope is that one or the other can be
 *       used with no real difference.
 *
 *    5) In the current version, if your platform can't represent
 *       int32_t, int16_t and int8_t, it just dumps out with a compiler
 *       error.
 *
 *    6) 64 bit integers may or may not be defined.  Test for their
 *       presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
 *       Note that this is different from the C99 specification which
 *       requires the existence of 64 bit support in the compiler.  If
 *       this is not defined for your platform, yet it is capable of
 *       dealing with 64 bits then it is because this file has not yet
 *       been extended to cover all of your system's capabilities.
 *
 *    7) (u)intptr_t may or may not be defined.  Test for its presence
 *       with the test: #ifdef PTRDIFF_MAX.  If this is not defined
 *       for your platform, then it is because this file has not yet
 *       been extended to cover all of your system's capabilities, not
 *       because its optional.
 *
 *    8) The following might not been defined even if your platform is
 *       capable of defining it:
 *
 *       WCHAR_MIN
 *       WCHAR_MAX
 *       (u)int64_t
 *       PTRDIFF_MIN
 *       PTRDIFF_MAX
 *       (u)intptr_t
 *
 *    9) The following have not been defined:
 *
 *       WINT_MIN
 *       WINT_MAX
 *
 *   10) The criteria for defining (u)int_least(*)_t isn't clear,
 *       except for systems which don't have a type that precisely
 *       defined 8, 16, or 32 bit types (which this include file does
 *       not support anyways). Default definitions have been given.
 *
 *   11) The criteria for defining (u)int_fast(*)_t isn't something I
 *       would trust to any particular compiler vendor or the ANSI C
 *       committee.  It is well known that "compatible systems" are
 *       commonly created that have very different performance
 *       characteristics from the systems they are compatible with,
 *       especially those whose vendors make both the compiler and the
 *       system.  Default definitions have been given, but its strongly
 *       recommended that users never use these definitions for any
 *       reason (they do *NOT* deliver any serious guarantee of
 *       improved performance -- not in this file, nor any vendor's
 *       stdint.h).
 *
 *   12) The following macros:
 *
 *       PRINTF_INTMAX_MODIFIER
 *       PRINTF_INT64_MODIFIER
 *       PRINTF_INT32_MODIFIER
 *       PRINTF_INT16_MODIFIER
 *       PRINTF_LEAST64_MODIFIER
 *       PRINTF_LEAST32_MODIFIER
 *       PRINTF_LEAST16_MODIFIER
 *       PRINTF_INTPTR_MODIFIER
 *
 *       are strings which have been defined as the modifiers required
 *       for the "d", "u" and "x" printf formats to correctly output
 *       (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
 *       (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
 *       PRINTF_INTPTR_MODIFIER is not defined for some systems which
 *       provide their own stdint.h.  PRINTF_INT64_MODIFIER is not
 *       defined if INT64_MAX is not defined.  These are an extension
 *       beyond what C99 specifies must be in stdint.h.
 *
 *       In addition, the following macros are defined:
 *
 *       PRINTF_INTMAX_HEX_WIDTH
 *       PRINTF_INT64_HEX_WIDTH
 *       PRINTF_INT32_HEX_WIDTH
 *       PRINTF_INT16_HEX_WIDTH
 *       PRINTF_INT8_HEX_WIDTH
 *       PRINTF_INTMAX_DEC_WIDTH
 *       PRINTF_INT64_DEC_WIDTH
 *       PRINTF_INT32_DEC_WIDTH
 *       PRINTF_INT16_DEC_WIDTH
 *       PRINTF_UINT8_DEC_WIDTH
 *       PRINTF_UINTMAX_DEC_WIDTH
 *       PRINTF_UINT64_DEC_WIDTH
 *       PRINTF_UINT32_DEC_WIDTH
 *       PRINTF_UINT16_DEC_WIDTH
 *       PRINTF_UINT8_DEC_WIDTH
 *
 *       Which specifies the maximum number of characters required to
 *       print the number of that type in either hexadecimal or decimal.
 *       These are an extension beyond what C99 specifies must be in
 *       stdint.h.
 *
 *  Compilers tested (all with 0 warnings at their highest respective
 *  settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
 *  bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
 *  .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
 *
 *  This file should be considered a work in progress.  Suggestions for
 *  improvements, especially those which increase coverage are strongly
 *  encouraged.

ZLIB DATA COMPRESSION LIBRARY

zlib 1.2.11 is a general purpose data compression library.  All the code is
zlib 1.3.1 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://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
rfc1952 (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

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.

- For 64-bit Irix, deflate.c must be compiled without any optimization. With
  -O, one libpng test fails. The test works in 32 bit mode (with the -n32
  compiler flag). The compiler bug has been reported to SGI.

- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
  when compiled with cc.

- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
- On Digital Unix 4.0D (formerly OSF/1) on AlphaServer, the cc option -std1 is
  necessary to get gzprintf working correctly. This is done by configure.

- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
  other compilers. Use "make test" to check your compiler.

- gzdopen is not supported on RISCOS or BEOS.

- For PalmOs, see http://palmzlib.sourceforge.net/

                        ZLib for Ada thick binding (ZLib.Ada)
                        Release 1.3

ZLib.Ada is a thick binding interface to the popular ZLib data
compression library, available at http://www.gzip.org/zlib/.
It provides Ada-style access to the ZLib C library.


        Here are the main changes since ZLib.Ada 1.2:

- Attension: ZLib.Read generic routine have a initialization requirement
  for Read_Last parameter now. It is a bit incompartible with previous version,
- Attention: ZLib.Read generic routine have a initialization requirement
  for Read_Last parameter now. It is a bit incompatible with previous version,
  but extends functionality, we could use new parameters Allow_Read_Some and
  Flush now.

- Added Is_Open routines to ZLib and ZLib.Streams packages.

- Add pragma Assert to check Stream_Element is 8 bit.

   File_Z    : ZLib.Streams.Stream_Type;

   Filter : ZLib.Filter_Type;

   Time_Stamp : Ada.Calendar.Time;

   procedure Generate_File;
   --  Generate file of spetsified size with some random data.
   --  Generate file of specified size with some random data.
   --  The random data is repeatable, for the good compression.

   procedure Compare_Streams
     (Left, Right : in out Root_Stream_Type'Class);
   --  The procedure compearing data in 2 streams.
   --  The procedure comparing data in 2 streams.
   --  It is for compare data before and after compression/decompression.

   procedure Compare_Files (Left, Right : String);
   --  Compare files. Based on the Compare_Streams.
