2004-07-21 Zoran Vasiljevic <zoran@archiware.com>

	* doc/*: reformatted docs and added some clarifications 
	about mutex handling.

	* generic/threadCmd.c: rewritten handling of thread handles
	as passed to Tcl. Instead of casting Tcl_ThreadId to unsigned int
	which brought some problems on Cray machines, we're now generating
	opaque handles and match them to Tcl_ThreadId internally.

	NOTE: this is not supposed to be a compatibility issue since
	thread-handles should have been treated as opaque anyways.

	* generic/threadSpCmd.*: improved behaviour when destroying locked
	mutexes and locking the same mutex twice from the same thread.
	In both cases we throw Tcl error instead of coring  the process
	or deadlocking the (naive) application.

	* generic/threadSvCmd.*: number of tsv buckets is now compile
	time constant.

	* lib/ttrace.tcl: Fixed error in unknown wrapper when the passed
	command was empty string.

	* tests/all.tcl
	* tests/thread.test: rewritten from scratch.

	* tests/tpool.test:
	* tests/ttrace.test:
	* tests/tsv.test: new files, currently no-ops.

2004-01-31 Zoran Vasiljevic <zoran@archiware.com>

	* lib/ttrace.tcl: added unconditional "package require"
	call to ttrace::eval so we need not explicitly load the
	Ttrace package in each and every thread. Also, fixed some
	issues with errorInfo/errorCode handling.

	* pkgIndex.tcl.in: fixed Tcl Bug #918137
	* doc/format.tcl: fixed inclusion of man.macros in
	every *.n doc file

2004-01-31 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: fixed incorrect handling of return
        codes from the scripts passed to threads. We were wrongly
        triggering error for non-error return codes such as TCL_RETURN,
	TCL_BREAK, TCL_CONTINUE etc. Now we trigger error only for
	TCL_ERROR and return other codes (as-is) to the caller.
	This also fixes the Tcl Bug #884549.

2003-12-22 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadSpCmd.c: added recursive and reader/writer locks
	and associated commands

	* generic/threadSpCmd.h: added new file

	* generic/lib/ttrace.tcl: added Ttrace package implementation

	* doc: added documentation for Ttrace package and synced other
	doc files to match the release 2.6 state.


2003-12-01 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: removed the concept of foreign
	thread since it broke our async message bouncing. We
	still have to find the way how we should avoid broadcasting
	non-package threads (like for aolserver).

2003-11-27 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: fixed mutex release in ThreadSend
	when refusing to send message to foreign thread.
	Also, clear the result of the thread::broadcast since it
	should not return anything to the caller, no matter the
	outcome of the command.

2003-11-27 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: mark threads created by the package
	to distinguish them from "foreign" threads. We will forbid
	sending messages to those since they will probably never listen.

	* generic/threadSvCmd.c: corrected some typos

	* generic/threadSvListCmd.c: added implementation for the
	"tsv::lset" command

	* generic/threadPoolCmd.c: added optional varname argument
	(last arg) to the tpool::cancel

2003-11-25 Zoran Vasiljevic <zoran@archiware.com>

	* doc/format.tcl: new file with a simple poor man's
	documentation formatter.

	* doc/thread.man
	* doc/tpool.man
	* doc/tsv.man: new doctools source files for building
	the package documentation.

	* Makefile.in: added support for building nroff and html
	files out of doctools sources found in doc directory.

2003-11-18 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: added implementation of the 
	thread::broadcast command. This one asynchronously 
	sends a script to all known threads, except the caller.

2003-09-03 Zoran Vasiljevic <zoran@archiware.com>

	* generic/tclXkeylist.(c|h): added keyed-list datatype
	implementation borrowed from the TclX package. This is
	now part of the shared variable command set.

	* generic/threadSvCmd.(c|h): modified to support persistent
	shared variables with plugin-architecture for different
	persistent store implementations.

	* generic/threadSvlistCmd.(c|h): modified to reflect added 
	support for persistent shared variables.

	* generic/psGdbm.(c|h): added persistent store wrapper
	for the GNU gdbm package.

	* configure et al: regenerated with autoconf because of
	added optional comilation with GNU gdbm. Updated makefiles
	to process newly added files for keyed lists and persistent
	stores.

2003-08-27 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadPoolCmd.c: after expiration of the idle
	timer, all idle workers exit unconditionaly. Before the
	change, idle threads exited after getting the first job
	posted. This way we were loosing work.

2003-08-26 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadPoolCmd.c: fixed result list corruption
	in TpoolCancelObjCmd. 

2003-07-27 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadPoolCmd.c: added "-nowait" option
	to the "tpool::post" commandi. This allows the 
 	caller to post jobs to the threadpool queue without
	waiting for an idle thread. The implementation will
	start at least one worker thread if there is none 
	available to satisfy the first request.
	Added "tpool::cancel" command. See docs for info.

2003-05-31 Zoran Vasiljevic <zoran@archiware.com>
	
	* generic/threadCmd.c: fixed ListRemoveInner for
	the Tcl Bug #746352

	* generic/threadSpCmd.c: modified Sp_Init to 
	return a proper value for Tcl Bug #746352

2003-05-17 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: sets the name of the new thread
	to "-tclthread-" when compiled for AOLserver

2003-04-29 Zoran Vasiljevic <zoran@archiware.com>

        Tagged interim 2.5.2 release.

	* configure.in
	* configure: Added quick fix for autoconf issues
        related to $srcdir and building of the package
        from the top-level dir instead of unix/win subdir.
        Thanks to Mo DeJong for the fix.

2003-04-10 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: removed checking of stopped flag
	during walk of the list of active threads. This
	solves some subtle thread reservation problems
	with threads marked to unwind on error.
	Also, added new "-errorstate" configuration option
	to set/get error state of reserved unwinding thread.
	
2003-04-02 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c:
	* generic/threadPoolCmd.c:
	* generic/threadSpCmd.c:
	* generic/threadSvCmd.c: always call registered exit callbacks
	with non-NULL clientData, otherwise Tcl won't invoke
	the registered  callback. 

2003-03-28 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadSvList.c
	* generic/threadSvCmd.c: fixed some rare cases
	where we incorrectly deep-copied the list object
	having zero elements.

	* generic/threadCmd.c: fixed broken AOLserver 3.x
	compatibility mode introduced by last 4.x changes.

2003-03-17 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadSvCmd.c: fixed incompatibility 
	with Tcl 8.4.2 filepath object

	* generic/threadCmd.c:
	* aolstub.cpp: adjusted for AOLserver 4.0
 
2003-02-24 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: fixed ThreadSetResult
	to correctly initialize all elements of the 
	result structure.

2003-02-08 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: fixed ListRemoveInner
	to correctly update global threadList ptr when 
	the last referenced thread exits. This was not
	the case before and we were trashing memory
	leading to process exitus.	

2003-01-25  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/threadCmd.c (ThreadSendObjCmd):
	The thread::send command was not working
	under Win32 because threads that had an id
	that was a negative number were generating
	a usage error in the thread::send command.
	* tests/thread.test: Add test for negative
	number as thread id.

2003-01-22 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: fixed reference to errorInfo
	when reporting error from the passed script.

2003-01-21  Mo DeJong  <mdejong@users.sourceforge.net>

	* configure: Regenerate to include recent fixes
	for mingw build support in tclconfig module.

2002-12-18 Zoran Vasiljevic <zoran@archiware.com>

	* README: added some AOLserver info
	* tcl/tpool/tpool.tcl: added missing tpool::names command

2002-12-14 Zoran Vasiljevic <zoran@archiware.com>

	* doc/*: finished docs for the 2.5 release

2002-12-09 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadPoolCmd.c: added tpool::names command
	added -exitscript for tpool::create

	* doc/tpool.tmml
	* doc/man/tpool.n
	* doc/html/tpool.html: added files. This is still the
	work in progress.

2002-12-06 Zoran Vasiljevic <zoran@archiware.com>

	* configure.in
	* configure
	* Makefile.in
	* aolserver.m4: added support for compilation under
	AOLserver as loadable module.

2002-12-06 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadSvCmd.c: the tsv::lock now allows
	for unsetting the shared array within the script argument.

	* generic/threadPoolCmd.c: fixed one missing mutex unlock
	in the ThreadRelease.

        * tcl/tpool/tpool.tcl: implemented missing API calls found
 	in the C-level implementation.

	* tcl/phttpd/phttpd.tcl: simplified switching to Tcl-level
	threadpool implementation. 	

2002-12-04 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadPoolcmd.c: rewritten to use
	worker threads sitting on the cond var instead of 
	in the event loop. The poster thread still respects
	i.e. does not block the event loop while posting jobs.

2002-12-03 Zoran Vasiljevic <zoran@archiware.com>

	* generic/tclthread.h: added SpliceIn/SpliceOut macros.
	Fixed to include exports from threadPoolCmd.c

	* generic/threadSpCmd.c: does regular namespace handling
	over the NS variable instead of hard-coding the "thread"
	prefix for mutex/cond commands.

	* generic/threadCmd.c: rewritten to use SpliceIn/SpliceOut
        macros instead of hand-fiddling with linked lists.

	* generic/threadPoolCmd.c: new file

	* Makefile.in: added threadPoolCmd.c to list of source files.

2002-11-25 Zoran Vasiljevic <zoran@archiware.com>

	* tcl/phttpd/phttpd.tcl: added raw file; no thread support
	* tcl/cmdsrv/cmdsrv.tcl: first working version

2002-11-24 Zoran Vasiljevic <zoran@archiware.com>

	* tcl/tpool/tpool.tcl: added threadpool implementation in Tcl
	* tcl/phttpd: added directory for later mt-enabled pico-httpd 
	* tcl/cmdsrv: added directory for later socket command server
	* doc/man/thread.n
	* doc/thread.tmml
	* doc/html/thread.html: new tsv::eval, thread::attach, thread::detach

	* generic/threadSvCmd.h
	* generic/threadSvCmd.c: added tsv::eval command

	* generic/threadCmd.c: added thread::attach, thread::detach
	Also, fixed thread::preserve and thread::release to accept
	the thread id as the optional paramter.
	
2002-11-23 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: fixed ListRemoveInner() to recognize
	and ignore already removed tsd thread structures. 
	Fixed some invalid TCL_OK returns which masked serious errors.
	
2002-11-07 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: fixes problem when trying to report
	the error from an async callback when the stderr channel is
	not available (wish/tclkit on windows). Thanks to 
	Wojciech Kocjan <wojciech@kocjan.org> for the correction.

2002-10-23 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: added handling of background errors
	while doing an async callback. 

2002-10-20 Zoran Vasiljevic <zoran@archiware.com>

	* doc/html/thread.html
	* doc/man/thread.n
	* doc/thread.tmml: fixed "thread::send" command summary.
	It was showing the wrong position of the "-async" argument.

	* generic/threadSpCmd.c: adjusted mutex/cond handles to
	use the same format and handling as AOLserver counterparts
	when compiled for AOLserver support. This way one can mix
	and match primitives declared with ns_mutex and thread::mutex
	and/or ns_event and thread::cond commands.
	Added thread::eval command. See documentation for syntax and usage.

2002-10-15  Jeff Hobbs  <jeffh@ActiveState.com>

	* configure:
	* configure.in: move the CFLAGS definition into TEA_ENABLE_SHARED
	and make it pick up the env CFLAGS at configure time.

2002-08-23 Zoran Vasiljevic <zoran@archiware.com>

	* threadCmd.c: fixed potential memory corruption
	when releasing preserved interpreter.
	[Tcl bug 599290]

2002-08-19 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadSvCmd.c: we now properly invalidate
	duped object string rep if the internal rep has been
	regenerated.

2002-08-18 Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: updated some comments
	* generic/threadSvCmd.c:
	* generic/threadSvListCmd.c: fixed silly mem leak
	where we were registering commands and object types
	for each new thread, resulting in unnecessary table
	grow. Not a memory leak per-se, therefore not found
	by Purify, but shows itself by observing the size
	of the process using the top utility. Gosh!

2002-08-03  Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadSvListCmd.c: corrected "tsv::lpush"
	to correctly make a copy of the object pushed into
	the list in shared array element.

2002-07-22  Mo DeJong  <mdejong@users.sourceforge.net>

	* README: Fix typo.
	* doc/man/thread.n: Note that thread::join and
	thread::transfer are only available with Tcl 8.4.

2002-07-20  Mo DeJong  <mdejong@users.sourceforge.net>

        * generic/threadSvCmd.c (Sv_tclEmptyStringRep, Sv_Init):
        Avoid linking to the tclEmptyStringRep variable defined
        in Tcl since this makes it very difficult to load
        the Thread package into an executable that has
        also loaded Tcl. The previous approach used a hack
        under Windows, we now use this same hack on all systems.
	[Tcl patch 584123]

2002-07-19  Zoran Vasiljevic <zoran@archiware.com>  

	* threadCmd.c: added some macros to simplify
	adding and removing result structure in and  
	out of the corresponding lists

2002-07-18  Zoran Vasiljevic <zoran@archiware.com>  

	* threadCmd.c: modified thread::release to allow
	for optional "-wait" argument. This will result in 
	the thread waiting until the target thread has really
	exited. Otherwise, the command exits immediately and 
	target thread may exit asynchronously some time later.
 	This is not techically needed since one can always join
	the exiting thread, but the join command is not 
	available for some older Tcl versions. 

2002-07-13  Zoran Vasiljevic <zoran@archiware.com>  

	* doc/man:
	* doc/html: added two directories with TMML generated files
	* doc/thread.tmml: fixed for the final 2.4 release
	* Makefile.in: updated install-doc target to look for man files
	under doc/man instead only under doc directory

2002-07-12  Zoran Vasiljevic <zoran@archiware.com>  

	* generic/threadSvCmd.s: fixed handling of string rep
	in shared var object duplicator

2002-07-09  Zoran Vasiljevic <zoran@archiware.com>  
	* README: added this file
 	* license.terms: added this file

2002-07-05  Zoran Vasiljevic <zoran@archiware.com>  

        * tclconfig/tcl.m4: fixed reference to MINGW so we can
	compile w/o MSVC under windows. 

2002-07-03  Zoran Vasiljevic <zoran@archiware.com>  

	* generic/threadSvCmd.c: simplified object duplicator

2002-06-17  Zoran Vasiljevic <zoran@archiware.com>  

	* generic/threadCmd.c: cleanup of some unused variables
	* generic/threadSvCmd.c:
	* generic/ThreadSpCmd.c:
	* generic/threadSvList.c: added CONST qualifiers to avoid warnings
	when compiling against 8.4 core. 

2002-05-25  Zoran Vasiljevic <zoran@archiware.com>  
	* generic/threadCmd.c: added some typecasts to satisfy Windows 
	* generic/threadSvCmd.h: added some typecasts to satisfy Windows 

2002-05-04  Zoran Vasiljevic <zoran@archiware.com>  
	* generic/threadSvCmd.c: removed errant reference to (still not)
	supported shared dictionary and shared keylist datatypes.

2002-04-27  Zoran Vasiljevic <zoran@archiware.com>  

	* generic/threadCmd.c: fixed processing of -eventmark. We now
	properly wait for target thread to catch up with processing events.

2002-04-07  Zoran Vasiljevic <zoran@archiware.com>  

	* generic/threadCmd.c: added call to Ns_TclMarkForDelete(interp)
	when compiled for AOLserver support, otherwise we were leaking std
	channels on thread exit.

2002-04-03  Jeff Hobbs  <jeffh@ActiveState.com>

	* Makefile.in: improved use of DESTDIR in install targets.
	Removed need for installdirs target.
	Broke TCLSH_PROG into TCLSH_ENV and TCLSH_PROG with TCLSH var and
	added comments about TCLSH_ENV.
	Added default shell and gdb targets.

	* configure: 
	* configure.in: updated to new TEA base that: prefixes all macros
	with TEA_* instead of SC_*; adds TEA_PREFIX, which defaults the
	prefix and exec_prefix values to what Tcl used; adds
	TEA_SETUP_COMPILER, which handles basic compiler / support program
	checks and simplifies the configure.in.  Turn on --enable-threads
	by default and do sanity checking as well.

2002-04-01  Jeff Hobbs  <jeffh@ActiveState.com>

	* Makefile.in (install-lib-binaries): ensure that binary files are
	installed with executable bit set (use INSTALL_PROGRAM)

2002-03-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* configure:
	* configure.in: BUILD_${PACKAGE} had to be static BUILD_thread in
	AC_DEFINE because autoconf wasn't substituting ${PACKAGE}.

2002-03-27  Jeff Hobbs  <jeffh@ActiveState.com>

	* Makefile.in (TCLSH_PROG): moved and updated env var definitions
	to have tclsh work from build dir.  Removed TCL_EXTRA_CFLAGS,
	TCL_LD_FLAGS, TCL_SHLIB_LD_LIBS, TCL_DBGX, TCL_STUB_LIB_FILE,
	TCL_STUB_LIB_SPEC as they aren't needed (configure acquires all
	that info for us).  TCL_LIBS is also not needed, but left in as a
	reference to the libs Tcl used.

	* configure: regen based on updated tclconfig/tcl.m4
	* configure.in: moved the SHLIB_LD_LIBS magic into
	tclconfig/tcl.m4 and noted where users can modify (SHLIB_LD_)LIBS.

2002-03-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclThread.h: 
	* generic/threadCmd.c: added stub voodoo magic to allow building
	against Tcl 8.3 and still get all the 8.4+ functionality when later
	loaded into an 8.4+ interp.

	* pkgIndex.tcl.in: simplified auto-generated pkgIndex.tcl file.

	* tests/all.tcl:
	* tests/thread.test: improved to detect 8.3/8.4 pkg differences

	* tclconfig/tcl.m4,install-sh (new):
	* config/* (removed):
	* aclocal.m4: 
	* configure: 
	* configure.in: 
	* Makefile.in: Updated build system to use tclconfig (TEA 2002)
	structure.

2002-03-09  Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadSvCmd.c: fixed memory leak when copying objects
	using custom object duplicator. If a duplicator was registered
	more than once, we were leaking memory.

2002-03-08  Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: added thread::configure -unwindonerror
	configuration option. See docs for usage.
	
	* doc/thread.n: added docs for thread::configure -unwindonerror
	
2002-03-07  Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadSvCmd.c: tsv::names will skip reporting shared
	arrays with leading dot in their names. This is turned-on 
	only for AOLserver builds with the HIDE_DOTNAMES. For the
	regular Tcl builds, all arrays are reported, regardless of
	the name. Motivation behind this feature is to allow certain
	data privacy. It is not name-clash proof, though.

2002-02-12  Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: fixed thread::preserve glitch. We never
	actually did bump the reservation counter by a silly mistake.

2002-02-12  Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: added thread::preserve and thread::release
	commands. These allow for a simple reference counting when creating
	and/or tearing-down threads. Instead of calling thread::unwind in
	the target thread, one can use "thread::release id" to dispose it.
	This is much easier to use and it can be coupled with calls to
	thread::preserve to implement simple thread reservation mechanism.

	* doc/thread.n: added docs for thread::preserve/thread::release
	
2002-02-09  Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: added thread::configure interface.
	Currently only "-eventmark" option is supported.
	Allows for AOLserver builds to change the "thread::" prefix
	by re-defining the "NS" compile-time constant.

	* doc/thread.n: added docs for thread::configure

2002-02-06  Zoran Vasiljevic <zoran@archiware.com>

	* generic/aolserv.cpp: (new) added for loading into the AOLserver.
	Still needs to fix the Makefile and friends to get it up and
	running.

	* generic/threadCmd.c: added conditional setup of the command
 	prefix. Now, the "NS" can be used to select the command prefix
 	for thread::* commands.

2002-01-26  David Gravereaux <davygrvy@pobox.com>

	* generic/threadSvCmd.c:  A small 'const' qualifier change to remove a
	warning.  It's a bit more wordy now, but reads a little clearer to me.
	Unscambling pointer math gives me a headache and combined with a cast
	tends to get dangerous.

	* win/threadWin.c: new idea for thread::kill added.  It's wrapped in an
	#if 0/#endif for now.  I do notice that tcl.h is now typedef'ing
	ClientData as an 'int *'.  It used to 'void *', didn't it??  The
	ISO/ANSI/CLEAN C style of setting a typed pointer to a void* now doesn't
	want to work.  Maybe I do too much C++ to have noticed this before...

2002-01-23  Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: fixed address of the target interpreter when
	doing the callback async script processing. All messages went to the
	main interpreter instead of the selected interpreter, causing process
	to hung when posting callbacks to more that one interp at the same time.
	(thanks Jean-Luc Fontaine for the tip)

2002-01-20  Zoran Vasiljevic <zoran@archiware.com>

	* generic/threadCmd.c: fixed multiple async reporting of error events
	(thanks Jean-Luc Fontaine for the tip)
   
2002-01-02  Zoran Vasiljevic <zoran@archiware.com>

        * generic/threadSvListCmd.* (new): added for the new implementation
        of the thread-shared-variable (tsv) interface.
        * generic/threadSvCmd.c: now uses shared Tcl objects instead of strings
        for storing data in shared arrays. This improves performance on large
        shared data structures.
        Added new tsv::* syntax, per request. This replaces older thread::sv_*
        interface. Older commands are still present but will be removed as
        soon we hit the 3.0 version.
        * generic/threadCmd.c: revamped to support asynchronous backfiring
        of scripts so we can vwait on the results of thread processing.
        This also corrected the bug #464340. Affected command is thread::send.
        * doc/thread.n: added docs for all thread::* and tsv::* commands.
        This fixes #416850 bug report. The html/tmml files are still out of date.
        * configure: built with autoconf 2.52
        * config/config.guess (new): needed for the new configure
        * config/config.sub (new): needed for the new configure
        * Makefile.in: added lines for new generic/threadSvListCmd.c
        * configure.in: moving to 2.4 version.
        * unix/threadUnix.c: removed traces of ThreadKill. It is still not clear
        wether we should implement this functionality or not.
        * win/threadWin.c: see above.
        * pkgIndex.tcl.in: fixed to correctly handle version for different Tcl core
        versions.

2001-09-05  David Gravereaux <davygrvy@pobox.com>

	* generic/*:
	* win/threadWin.c (new): updated for a new threadWin.c and finished
	replacing use of thread.h with tclThread.h.  threadWin.c is an
	experiment to add a 'thread::kill' command.  Not done yet.

	* win/vc/thread.rc (removed):
	* win/thread.rc (new): moved it up a directory.

2001-09-04  David Gravereaux <davygrvy@pobox.com>

	* generic/thread.h (deleted):
	* generic/tclThread.h (new):
	* generic/threadCmd.c:  decided to change the name of 'thread.h' to
	'tclThread.h', per request.

	* generic/thread.h:
	* generic/threadCmd.c:  Re-added original implimentation of [thread::exit].
	for `emergency use only`.  You have been warned ;)

	* configure.in:
	* configure:
	* win/vc/thread.dsp:
	* win/vc/pkg.vc:  Upped version numbers to 2.3 and 2.1.3 because I just cut
	a release.

2001-09-04  David Gravereaux <davygrvy@pobox.com>

	-=[ Official 2.2 Tagged and cut. ]=-

2001-05-27  David Gravereaux <davygrvy@pobox.com>

	* tests/thread.test: fixed small typo in comments.

2001-08-03  Jeff Hobbs  <jeffh@ActiveState.com>

	* Makefile.in: corrected handling of VERSION

	* generic/threadCmd.c:
	* generic/thread.h: added Thread_SafeInit

	* win/vc/makefile.vc: added -DBUILD_thread to cflags.

2001-05-27  David Gravereaux <davygrvy@pobox.com>

	* configure:
	* configure.in:
	* Makefile.in:
		Added package versions to the compile flags. [bug #421246]

2001-04-28  David Gravereaux <davygrvy@pobox.com>

	* generic/threadCmd.c (NewThread): removed the previous addition of
	Tcl_FinalizeThread.  Tcl_ExitThread calls it anyways (my mistake).
	The resource leak was in the core.  See ->
	http://sourceforge.net/tracker/?func=detail&atid=110894&aid=419683&group_id=10894
	for the fix.  That patch is pending approval.

	To acheive the same behavior of emptying the event loop the way
	thread::wait used to work, use the following:
		set T [thread::create {thread::wait; update}]
		thread::send -async $T thread::unwind

	* generic/thread.h:
	* win/vc/makefile.vc:
	* win/vc/thread.rc:
	* win/vc/pkg.vc (new): Moved version numbers from the header file.  It isn't
	an export API or anything.  Moved version numbers to the build files.  I'll
	modify configure.in and makefile.in a little later.

2001-04-26  David Gravereaux <davygrvy@pobox.com>

	* config/* (new): old site-wide config directory re-added.

	* generic/threadCmd.c (ThreadEventProc): ThreadErrorProc now
	supported in asyncronous sends when Tcl_Eval returns other than
	TCL_OK.  Errors were silently ignored prior to this. Bug #219324

	==== INTERFACE CHANGE ====
	* generic/threadCmd.c:
	* generic/thread.h: thread::exit renamed to thread::unwind. The
	name of 'exit' is misleading.  An exit implies an unconditional
	return.  But there are conditions.  'unwind' describes with more
	clarity what's happening to the prior thread::wait.  For example:

	  # parent thread
	  set T [thread::create {source worker.tcl}]
	  ....
	  thread::send -async $T doStuff
	  ....
	  thread::send -async $T doStuff
	  ....
	  thread::send -async $T thread::unwind

	  # worker.tcl
	  proc init    {} {#do initialization}
	  proc cleanup {} {#do cleanup}
	  proc doStuff {} {#the work}
	  init
	  thread::wait
	  cleanup

	When worker.tcl is sourced, the execution stops at thread::wait and
	the event loop is entered.  When thread::unwind is sent to the worker,
	thread::wait falls-out and cleanup is called.  The condition for
	thread::unwind to cause an exit is determined by the script.  If
	thread::wait was the last Tcl command in the script, yes the thread
	will exit.  But if thread::wait is not the last, the execution of the
	script is just continued.  Hence, the name change to clarify this fact.

	Package version has not been changed.  There hasn't been an official
	release of 2.2, so it stays.

	* doc/thread.n:
	* tests/thread.test: Replaced thread::exit with thread::unwind and
	documented the change and clarified the subtleties.

	* win/vc/makefile.vc:
	* win/vc/thread.dsp: Changed NODEBUG macro to be DEBUG instead.
	Double negatives give me a headache.  DEBUG=1 makes more sense
	to me than NODEBUG=0.  Not that I didn't think you wouldn't have
	disagreed it was confusing, no?

	* win/vc/config.vc: Added a reminder to edit before using.
	* win/vc/thread.rc: Added authors and removed the Ajuba branding.

2001-04-25  David Gravereaux <davygrvy@pobox.com>

	* generic/threadCmd.c (ThreadWait)(NewThread): Removed the event
	loop sinking which was probably done because Tcl_FinalizeThread
	was missing from NewThread().  Now the event loop is cleaned
	by Tcl_FinalizeThread and ThreadWait doesn't manipulate events
	that don't belong to it.  Bug #418689 and #418693

	* generic/threadCmd.c (Thread_Init): logic fix in a version check
	for determining the 8.3 package subset.

2000-11-02  David Gravereaux <davygrvy@ajubasolutions.com>

	* generic/threadCmd.c (NewThread): Added logic to test for a
	working Tcl_Init() based on the core version at runtime and ignore
	its failure in versions 8.3.[1,2] and 8.4a1.  [BUG: 5301]

2000-10-26  David Gravereaux <davygrvy@ajubasolutions.com>

	* generic/thread.h:
	* win/vc/config.vc:
	* win/vc/makefile.vc:
	* win/vc/thread.dsp: upped version numbers to 2.2 along with adding
	a new macro (THREAD_VERSION_SUBSET83) defining the version when
	loaded into an 8.3 core.  Which happens to be "2.1.1" at this time.

	* generic/threadCmd.c (Thread_Init): Added logic to allow setting
	the package version at runtime to "2.2" when compiled against 8.4
	and loaded into 8.4.  When compiled against 8.4, yet loaded into
	8.3, thread::join and thread::transfer are not added to the interp
	and the package version is set to "2.1.1" instead from the single
	binary.  [ie. multiple interfaces in one binary]  When compiled
	against 8.3, thread::join and thread::transfer are non-existant and
	the package version is always "2.1.1" to maintain a consistent
	interface in all combinations (as per discussions with Don Porter).

2000-10-16  Zoran Vasiljevic <zoran@munich.com>

	* generic/threadSvCmd.c ThreadSvUnsetObjCmd(): deadlocked.
        Forgot to release shared-array lock which resulted in
        deadlock after first successful unset of the variable.

2000-08-29  David Gravereaux <davygrvy@ajubasolutions.com>

	* generic/threadCmd.c (NewThread): Tcl_Init return value wasn't
	being verified.  Added a check and failure logic to fall-out.
	[Bug: 5301]

2000-08-28  David Gravereaux <davygrvy@ajubasolutions.com>

	* generic/threadCmds.c (Thread_Init): Added logic to enable
	thread::join and thread::transfer when loaded into an 8.4+ core.
	We don't want a seg fault when the Stubs tables don't match for
	the functions that don't exist in an 8.3 core.

2000-08-23  Brent Welch <welch@ajubasolutions.com>

	* configure.in:
	* win/vc/makefile.vc: Changed to version 2.1
	* generic/threadCmds.c: Made the code that uses new Tcl 8.4 APIs
	conditional using #ifdef.  Tested with 8.3.2
	* Applied thread-2-1 tag for use with tclhttpd bundled release.

2000-08-21  David Gravereaux <davygrvy@ajubasolutions.com>

	* win/vc/makefile.vc:
	* win/vc/thread.rc: added version numbers to filename to follow
	Tcl standards.

	* doc/thread.tmml(new): Initial TMML document.

2000-08-20  David Gravereaux <davygrvy@ajubasolutions.com>

	* win/vc/config.vc:
	* win/vc/makefile.vc:
	* win/vc/README.txt:
	* win/vc/thread.dsp:  A near top down rewrite that adds
	four more build configurations.  See README.TXT for the
	details.

	* win/vc/.cvsignore:  A few more glob patterns added to match
	the new build directories.

2000-08-09  David Gravereaux <davygrvy@ajubasolutions.com>

	* win/vc/thread.rc: swapped "Scriptics Corp" for "Ajuba
	Solutions"

	* win/vc/config.vc:
	* win/vc/makefile.vc: cleaned-up old cruft.  Added new files
	from Zoran's patches.  made swapping to MSDev 6.0 easier.
	Removed the '!if $(_NMAKE_VER) > 162' test for 2 reasons.

	1) batchmode inference rules are valid since MSDev 5.0 and
	the core can't be built with less.  So don't bother testing.

	2) nmake.exe that comes with MSDev 6.0 has a bug with the
	meaning of that macro and MS decided to use a string instead
	breaking the integer comparison test.

	Also added vcvars32.bat to a new setup rule and got config.vc
	much smaller.

	* win/vc/thread.dsp: Added new files from Zoran's patch.

	* win/.cvsignore(deleted):
	* win/vc/.cvsignore(added): moved file to help keep a cleaner
	build environment.

	* generic/threadSvCmd.c: Added some additional casting of
	Tcl_GetHashValue to prevent compiler warnings.

	* generic/threadCmd.c(ThreadWait): Removed the event loop
	sinking after the "while(..) Tcl_DoOneEvent();" because this
	extension is only responsible for it's own events in the event
	loop.  Any other extension that's queueing events must be
	responsible for it's own cleanup and should be aware of when
	the interp (ie. this thread) is going away when we fall-out
	to Tcl_DeleteInterp from the Tcl_Eval in NewThread().  If other
	extensions (like Tk) don't become aware, then they need to add
	a Tcl_CallWhenDeleted handler.

2000-07-14 Zoran Vasiljevic <zoran@munich.com>

	* generic/threadCmd.c: improved thread::exit behaviour
	  now does a better job of draining the event loop before exit.
	  may have some wishes open, though - see ThreadWait().
	
	* generic/threadSpCmd.c, generic/threadSvCmd.c:
	  added some comments in function headers.
	  docs/tests for above still pending.
	
2000-07-03 Zoran Vasiljevic <zoran@munich.com>
	
   	Summary of changes:

	* generic/threadSpCmd.c: new file with implementation of 
	  "thread::mutex" and "thread::cond" commands. Documentation 
	  and tests are still pending.
	
	* generic/threadSvCmd.c: new file with implementation of 
	  "thread::sv_*" family of commands modeled after AOLserver
	  nsv_* ones. Documentation and tests are still pending.

	* Makefile.in: fixed for the two above

	* doc/thread.html 
	* doc/thread.n: added 'thread::exists' docs

	* generic/thread.h added declarations for new commands (above)
	
	* generic/threadCmd.c:
	
	  Added "thread::exists" command.

	  Moved most of internal functions in threadCmd.c to statics,
          except the Thread*ObjCmd(). 

	  Changed behaviour of "thread::exit". It now simply flips the
          bit to signal thread stuck in thread::wait to gracefuly exit.
          Consequence: command now does not trigger error on thread exit.
          Also, thread event queue is now properly cleared.
          ThreadWait() and ThreadStop() are newly added to support this.
          Also the ThreadSpecificData has one more integer: "stopped"

	  Replaced ref's to obsolete Tcl_GlobalEval() with Tcl_EvalEx().

	  Fixed broken 'thread::create -joinable script';
          was missing initialization of script variable

	  Added calls to initialize new commands in threadSpCmd.c
	  and threadSvCmd.c files.

2000-05-18 Brent Welch <welch@scriptics.com>

	* Restored Andreas' changes for transferring sockets.

2000-05-16 Brent Welch <welch@scriptics.com>

	* Temprarily rolled back Andreas' changes so I can fix up
	the 2.0 release (configure and Make).  Also need to apply
	a 2.0 tag.

2000-05-09 Andreas Kupries  <a.kupries@westend.com>

	* tests/thread.test: Removed dependency on aclocals.m4. Using a
	  real temporary file now, as created by a call to
	  tcltest::makeFile. Updated test 6.3 to use the correct length
	  information.

2000-05-04  Andreas Kupries <a.kupries@westend.com>

	* Overall changes:
	  (1) Added joinable threads.
	  (2) Added transfer of channels between threads.

	* generic/threadCmd.c: Added functions Thread_Join and
	  ThreadJoinObjCmd.

	  Extended function ThreadCreateObjCmd to handle a
	  -joinable flag.

	  Fixed bug in Thread_Create, the argument 'stacksize' was not
	  used.

	  Removed declaration of ThreadObjCmd, which was not used anywhere
	  else in the code.

	  Added functions Thread_Transfer, ThreadTransferEventProc and
	  ThreadTransferObjCmd. Extended behaviour of ThreadDeleteEvent
	  and ThreadExitProc to deal with the new class of events.

	  Changed usage of ckfree to the more canonical Tcl_Free. Same for
	  ckalloc and Tcl_Alloc.

	* Makefile.in: Fixed bug with regard to the installation of
	  documentation.

	* doc/thread.*: Added documentation of create -joinable,
	  thread::join and thread::transfer.

	* tests/thread.test: Added tests for joining of threads and moving
	  channels between threads.

2000-04-19  Brent Welch <welch@scriptics.com>

	* win/vc/config.rc, Makefile.vc: Fixes from David Gravereaux

2000-04-18  Brent Welch <welch@scriptics.com>

	* Makefile.in: Fixes for make install

2000-04-17  Brent Welch <welch@scriptics.com>

	* generic/threadCmd.c
	Added Tcl_CreateThreadType and TCL_RETURN_THREAD_TYPE
	macros for declaring the NewThread callback proc.

2000-04-11  Brent Welch <welch@scriptics.com>

	* Picked up minor changes from David Gravereaux <davygrvy@bigfoot.com>
	* for compilation on windows with his alternate project files.

2000-04-10  Brent Welch <welch@scriptics.com>

	* Moved all the configure.in, Makefile.in etc. up to the top level out
	* of the unix (and win) subdirectories.  These are now shared.
	* If you are using CVS, you'll want to get the "config" module into
	* this directory, or do the checkout of thread again so the config
	* module is brought in.  You should have a "config" subdirectory of
	* your main thread workspace directory.

2000-04-09  Brent Welch <welch@scriptics.com>

	* Updated to compile against 8.3.1 export thread APIs
	* Added Windows makefiles

2000-03-27  Brent Welch <welch@scriptics.com> (proxy for Andreas Kupries)

	* tests/all.tcl: Added this file
	* tests/thread.test: fixed to use tcltest
	* doc/thread.n: Added this file as clone of thread.html
	# doc/thread.html: fixed typo
