Additional functionality to switch off TIP 143/285 functionality for static builds. 2012-11-10 Zoran Vasiljevic * genric/threadCmd.c: fixed race condition on thread-local storage in ThreadCancel(). 2012-11-10 Zoran Vasiljevic *** Merged "thread-2-7for84+" branch *** 2012-11-08 Don Porter * configure.in: Bump to version 2.7.0 * lib/ttrace.tcl: * win/pkg.vc: 2012-09-13 Zoran Vasiljevic *** 2.7b1 TAGGED FOR RELEASE (thread-2-7-b1) *** * doc/html/tpool.html * doc/man/tpool.n * doc/tpool.man: fixed "tpool::create -idletime" description [Tcl Bug 3534442] * generic/threadSpCmd.h * generic/threadSvCmd.h: removed some unused structure members [Tcl Feature Request 3563391] 2012-09-11 Jan Nijtmans * Makefile.in: Use "::tcltest::loadTestedCommands" to make * tests/all.tcl: sure that the right Thread version is tested, * tests/thread.test: without requiring explicit version numbers 2012-08-29 Jan Nijtmans * generic/*.c: Remove all (deprecated) usages of _ANSI_ARGS_ and TCL_PARSE_PART1 * generic/threadSpCmd.c: Fix [Tcl Bug #3562640]: problem loading Thread * generic/threadSvCmd.c: in 8.5, when compiled for 8.6. * win/makefile.vc * Makefile.in 2012-07-17 Jan Nijtmans * win/makefile.vc: [Bug 3544932]: Visual studio compiler check fails 2012-07-05 Zoran Vasiljevic * generic/threadCmd.c: Fixed leaking callback data in ThreadSend() plus some minor cosmetic changes (tx to Gustaf Neumann). 2012-07-03 Zoran Vasiljevic * generic/threadPoolCmd.c: [Bugs 3534440, 3534581] fixed. Also, promoted jobId to be Tcl_WideInt (was uint). 2012-04-26 Don Porter * generic/threadSpCmd.c: Eliminate some tricky finalization problems by converting the SpBucket arrays from dynamic storage to static storage so they no longer need to be finalized. Since they have fixed size of NUMSPBUCKETS, I don't see any strong reason not to do this. 2012-04-24 Don Porter * generic/threadCmd.c: [Bug 1603234] Stop leak in [thread::transfer]. 2011-12-05 Joe Mistachkin * generic/threadCmd.c: Fix #define issue when compiling for Tcl 8.5. 2011-11-24 Jan Nijtmans * generic/tclThread.h: Only export Thread_Init(), nothing more. * generic/tclXkeylist.h * generic/threadSpCmd.h * generic/threadSvCmd.h * generic/threadSvCmd.c * generic/threadSvKeylistCmd.h * generic/threadSvListCmd.h 2011-11-20 Joe Mistachkin * generic/threadCmd.c: Correct check for current thread in the ThreadReserve function [Bug 3411244]. Correct the order for releasing the interpreter and freeing memory, see check-in [6067508840]. 2011-11-17 Joe Mistachkin * generic/threadCmd.c: Refactor ThreadEventProc to make sure all paths out of the function call Tcl_Release on the necessary Tcl interpreters. Also, call ThreadErrorProc consistently whenever the return code is not TCL_OK (i.e. do not check for it to be equal to TCL_ERROR). 2011-11-17 Joe Mistachkin * generic/threadCmd.c: The [thread::wait] command should use the TCL_CANCEL_UNWIND flag when calling Tcl_Canceled because it manages its own event processing loop. Also, if the event processing loop is terminated due to a script in progress being canceled or exceeding a runtime limit, the registered error script should be evaluated, if any. 2011-11-17 Joe Mistachkin * generic/threadCmd.c: The [thread::wait] command must cooperate with the interpreter resource limiting (TIP #143) and asynchronous script cancellation (TIP #285) functionality, when available. 2011-11-17 Joe Mistachkin * generic/threadCmd.c: For [thread::cancel], avoid creating a new Tcl_Obj when the default script cancellation result is desired. * doc/thread.man: Update all remaining versions to 2.7b1. * doc/tpool.man: * doc/tsv.man: * doc/ttrace.man: * lib/ttrace.tcl: * win/vc/pkg.vc: * win/vc/thread_win.dsp: * win/vc/makefile.vc: Stop using -debug:full as it causes an error with the MSVC10 compiler. 2011-09-12 Joe Mistachkin * generic/threadCmd.c: Add support for TIP #285 (asynchronous script cancellation) via a new [thread::cancel] command (available only for Tcl 8.6). * win/vc/makefile.vc: Correct path to root of source checkout. 2011-08-01 Don Porter * win/vc/rules.vc: Extend support to MSVC10. Thanks to Twylite. 2011-06-27 Don Porter * configure.in: Copied revisions from the "sampleextension" package * Makefile.in: to keep compatible with the latest INSTALL changes in TEA 3.9. * configure: autoconf-2.59 2010-12-08 Zoran Vasiljevic * generic/threadCmd.c: Fixed Bug #3129844 2010-11-18 Don Porter * Makefile.in: Revised the `make dist` target so that the * win/README.txt: files under thread/win/vc in CVS are copied to * win/vc/makefile.vc: thread/win in the release, where tcl/pkgs/ * win/vc/thread_win.dsp: expects to find them. * configure: autoconf-2.59 2010-10-04 Zoran Vasiljevic * generic/configure Regenrated for TEA 3.9. Bumped version string * generic/configiue.in in all relevant files to 2.6.7 and autoconf'ed. * win/vc/pkg.vc 2010-09-28 Zoran Vasiljevic * generic/threadCmd.c: Initialize tsdPtr->interp to NULL immediately after releasing the interp on thread-exit that should hopefully resolve the Tcl Bug #3026061 * generic/threadCmd.c: Removed safe-init so safe-interps should not be able to run thread commands directly. * lib/ttrace.tcl: Changed version to 2.6.7 to be in sync with main pkg. * configure.in: Bumped version to 2.6.7 and autoconf'ed. 2010-09-05 Donal K. Fellows * doc/tpool.man, doc/tsv.man: Remove spaces in titledesc declaration; doctools currently does not like it at all when generating correct nroff output. 2010-08-12 Andreas Kupries * lib/ttrace.tcl (_serializensp, _serializeproc): Fixed typos which smashed namespace name and opening brace of a script together, leading to a syntax error for 'namespace eval' and preventing the use of package Ttrace. 2010-07-25 Donal K. Fellows * lib/ttrace.tcl: [Bug 3033206]: Be careful with variables outside of procedures; Tcl's variable resolution rules can jump in if a variable is not declared, which can be at best surprising. Also rewrote the namespace serialization code to be more robust. 2010-05-31 Andreas Kupries * pkgIndex.tcl.in: Fixed procedure collisions for Thread package by inlining the load command into the ifneeded script, as is standard for most binary packages. Tweaked the procedure for Ttrace a bit, as the result of [info commands] is a list, and using ::apply when possible. A named procedure is only a fallback. 2010-05-27 Andreas Kupries * lib/ttrace.tcl: Resynchronized version number with Thread. 2010-05-26 Andreas Kupries * generic/threadSpCmd.c (ThreadMutexObjCmd, ThreadRWMutexObjCmd): [Bug 3007426]: Dropped trailing commas in enum definitions which choked the strictly C89 AIX compiler. 2010-04-01 Zoran Vasiljevic * generic/tclXkeylist.c: Removed declaration of global TclX keylist commands. 2010-03-30 Zoran Vasiljevic *** 2.6.6 TAGGED FOR RELEASE (thread-2-6-6) *** * configure: Redo for TEA 3.7 * configure.in: * generic/tclThread.h: Cosmetic changes for the inclusion * generic/threadCmd.c: in standard Tcl distribution. * generic/threadPoolCmd.c: * generic/threadSpCmd.c: * generic/threadSvCmd.c: * generic/threadSvCmd.h: 2010-03-19 Jan Nijtmans * generic/threadSpCmd.c: Silence gcc warning: dereferencing * .cvsignore: type-punned pointer will break strict-aliasing rules. * configure: Regenerated using latest TEA 2009-08-19 Zoran Vasiljevic * generic/threadPoolCmd.c: Implemented [tpool::suspend] * doc/tpool.man: and [tpool::resume] commands as per [RFE #2835615].

Failure to create one results in partial pool teardown. Fix for [Bug #2005794]. 2008-05-22 Zoran Vasiljevic * generic/threadSpCmd.h: Added one cond variable per sync bucket to wait for item deletion. * generic/threadSpCmd.c: Threads that want to delete any sync primitive now wait properly until the last thread that references the primitive detaches. Fixed (broken) reference counting of items. Fixed wrong release of an condition variable that is about to be time-waited. 2008-05-18 Zoran Vasiljevic * generic/threadPoolCmd.c: Corrected potential race condition in TpoolWorker(). 2007-06-30 Zoran Vasiljevic * generic/threadPoolCmd.c: Fixed signedness compiler warning on jobId in TpoolWaitObjCmd(). 2007-06-30 Zoran Vasiljevic * generic/threadSvKeylistCmd.c: Fixed off-by-1 error in argument parsing for SvKeylkeysObjCmd().

(support for non-intel build * win/vc/makefile.vc: and recent versions of msvc compiler) * win/thread.rc: Fixed line endings. 2006-12-26 Zoran Vasiljevic * generic/threadCmd.c: Fixed race condition for creating preserved threads. * generic/threadSv.c: Removed memory leak. 2006-10-07 Zoran Vasiljevic *** 2.6.5 TAGGED FOR RELEASE (thread-2-6-5) *** Main changes since the last release: ------------------------------------ Set versioning of (embedded) Ttrace package to the same revision level as the main Thread package. The Ttrace must now explicitly be loaded in every new thread created by [thread::create] command. The [package require Ttrace] automatically loads Thread package as well. NOTE: be sure to configure/make/make install because the pkgIndex.tcl loader file is modified. 2006-10-06 Zoran Vasiljevic * generic/threadPool.c: * generic/threadCmd.c: Removed Tcl_PkgRequire from the new thread initialization and just initialize the C-aspect of the extension by calling Therad_Init. This basically discards the last checkin, which was in a sense bad as it made thread creation very expensive operation. * pkgIndex.tcl.in: Added separate handling for Ttrace loading. Now, users needing Ttrace caps must "package require Ttrace" which in turn automatically calls "package require Thread". Also, each new thread created by [thread::create] must be initialized for Ttrace by calling the [package require Ttrace]. On the other hand, the "package require Thread" is only necessary to first-load the package in the startup thread. It is not necessary to call this explicitly in every thread created by the [thread::create] command as the C-code will do that automatically as the first thing. * doc/ttrace.man: Updated example usage to reflect above changes. * lib/ttrace.tcl: Spliced version numbering of the Ttrace package to the version of the Thread package because of the weirdness of the Tcl package loading mechanism. Also, the broadcast script used within the ttrace::eval now explicitly loads Ttrace package in every broadcasted thread. 2006-10-05 Zoran Vasiljevic * generic/threadPool.c: * generic/threadCmd.c: Call Tcl_PkgRequire() in the NewThread() to properly initialize the extension in any new thread. * doc/ttrace.man: Add small example of ttrace usage. * lib/ttrace.tcl: Fixed [ttrace:eval] to not to call [package require Ttrace] in the broadcast script as this is now done implicitly for all new threads. 2006-08-06 Zoran Vasiljevic *** 2.6.4 TAGGED FOR RELEASE (thread-2-6-4) *** * generic/tclXkeylist.c: Silenced various * generic/threadCmd.c compiler warnings. * generic/threadSvCmd.c: * README: Removed version information. * configure.in: Bumped to 2.6.4 version. * confiigure: Regenerated. 2006-06-04 Zoran Vasiljevic * generic/threadSvCmd.c: SvIncrObjCmd() now implicitly creates shared array and/or element and initializes it to zero if the array and/or the element were not found. * generic/tclThread.h: Removed some unusded debugging defs 2006-04-05 Jeff Hobbs * win/vc/pkg.vc (PACKAGE_VERSION): correct to 2.6.3 for MSVC make. 2006-03-28 Jeff Hobbs * generic/threadPoolCmd.c (AppExitHandler): fix teardown to destruct pool list correctly. [Bug 1427570] 2006-03-16 Zoran Vasiljevic *** 2.6.3 TAGGED FOR RELEASE (thread-2-6-3) *** * README: Bumped to 2.6.3 2006-03-15 Zoran Vasiljevic * configure.in: Changed BUILD_sample to BUILD_thread for Windows compile under MinGW. + configure: regen 2006-03-14 Zoran Vasiljevic * configure.in: Moved to 2.6.3 release * configure: regen 2006-02-09 Zoran Vasiljevic * generic/threadSpCmd.c: fixed race condition when testing constraints (mutex being locked by the caller thread) when waiting on the condition variable. Also, fixed exclusive mutex ownership and usage counting. * configure.in: uses TEA 3.5 * tclconfig: updated to TEA3.5 2006-01-28 Zoran Vasiljevic * generic/threadSpCmd.c: Revamped handling because of the deep * generic/threadSpCmd.h: race condition which resulted in * tests/thread.test: deadlocks when using exclusive mutexes. 200i-10-15 Zoran Vasiljevic * generic/threadCmd.c: channel transfer code cleans ready-to-fire events from the thread event queue prior to cutting the channel out of the interp. * tests/thread.test: allows channel transfer tests for all Unices and Windows using Tcl 8.4.10+ core. 2005-09-23 Zoran Vasiljevic * generic/threadCmd.c: ThreadDetach() sets the both source and target thread ID's for the detached channel to zero, thus signalizing the cleanup code to leave the channel in the cleanup-list when the thread who detached it exits. 2005-08-24 Zoran Vasiljevic * generic/tclXkeylist.c: made some calls static so they do not interfere for static linking with certain extensions. 2005-08-08 Zoran Vasiljevic * generic/threadSvCmd.c: fixed traversing the list of registered object types in Sv_DuplicateObj() (thx to eric.melbardis@netkitsolutions.com) 2005-07-27 Zoran Vasiljevic *** 2.6.2 TAGGED FOR RELEASE (thread-2-6-2) *** * configure: regen * unix/README: added some clarifications about usage of --with-gdbm switch * README: * configure.in: bumped version to 2.6.2 * aclocal.m4: fixed for alternate gdbm lib location as per patch request #1245204 * generic/tclThread.c: removed Thread_Unload and Thread_SafeUnload because we can't really be unloaded. * html/thread.html: regen * html/tpool.html: regen * html/tsv.html: regen * html/ttrace.html: regen * man/thread.n: regen * man/tpool.n: regen * man/tsv.n: regen * man/ttrace.n: regen 2005-07-26 Mo DeJong * Makefile.in: Remove SYSTEM_TCLSH and any code that tries to run tclsh at build time aside from running the test cases. * configure: Regen. * configure.in: Remove calls to TEA_BUILD_TCLSH and TEA_BUILD_WISH since these were removed from tcl.m4. This fixes up the build when --with-tcl indicates either a build dir or and install dir. 2005-07-25 Zoran Vasiljevic * pkgIndex.tcl.in: simplified by introducing a helper procedure, thus avoiding too much quoting. 2005-07-24 Mo DeJong * Makefile.in: Subst TCLSH_PROG as SYSTEM_TCLSH and subst BUILD_TCLSH and BUILD_TCLSH_PROG. * configure: Regen. * configure.in: Invoke TEA_BUILD_TCLSH from tcl.m4 to correctly determine BUILD_TCLSH. 2005-04-12 Zoran Vasiljevic * generic/tclThread.h: * generic/threadCmd.c: reverted some changes by the last checkin which slipped in by mistake 2005-04-09 Zoran Vasiljevic * generic/tclThread.h: * generic/threadCmd.c: added Thread_Unload and Thread_SafeUnload to be able to load into the 8.5 shell. Both calls are still no-ops. 2005-03-18 Jeff Hobbs * Makefile.in (AR): use @AR@ (TCLSH_ENV): add TCL_THREAD_LIBRARY var * pkgIndex.tcl.in: grok TCL_THREAD_LIBRARY var * configure, configure.in: update to TEA 3.2 2005-03-15 Zoran Vasiljevic * pkgIndex.tcl.in: Applied patch for Bug #1163357. Also, fixed the case when directory path contains blanks. 2005-03-05 Zoran Vasiljevic * generic/threadSvCmd.c: fixed potential access to the unlocked (and thus eventually freed) container * lib/ttrace.tcl: the overloaded [info] command now does the right thing when applied to non-existing procedures. We now transparently resolve them and then allow the [info] to operate on them. The ttrace::enable can now be called recursively. Also, fixed stript generation issues for namespaced variables containing wild escape sequences. 2005-01-03 Zoran Vasiljevic * generic/threadPoolCmd.c: fixed Tcl Bug #1095370. We were wrongly tearing down workers on idle timer expiry *below* the number of workers set by the "-minworkers" option. * lib/ttrace.tcl: added [ttrace::config] to control some runtime options. The only option it allows now is "-doepochs". This is a boolean flag turning the epoch generation off/on. Also, improved handling of XOTcl introspections in regard to namespaced objects/classes. 2005-01-03 Zoran Vasiljevic * lib/ttrace.tcl: added [ttrace::isenabled] and modified the [ttrace::addtrace] to dynamically activate the tracer if the tracing is already enabled. This way we can dynamically load tracer scripts. 2005-01-03 Zoran Vasiljevic **** RELEASE: 2.6.1 Tagged **** * aolserver.m4: * configure.in: * configure: rebuild and include conditional compilation for AOLserver which was wrongly ommited since the switch to the TEA3 build system. Also, we will now revert to .. version numbers for all releases. * generic/threadCmd.c: added new option "-head" to the [thread::send] command so scripts can be placed on the head of the thread event queue instead of the tail only. * doc: rebuild html/nroff files from doctools sources * generic/threadPoolCmd.c: * generic/threadSvCmd.h: * generic/tclThread.h: removed compat macros for 8.3 core * test/thread.test: added case for [thread::send -head] 2004-12-23 Zoran Vasiljevic **** RELEASE: 2.6 Tagged **** * tcl/cmdsrv/cmdsrv.tcl: example command server listens on loopback interface (127.0.0.1) only * README: removed stuff about (now unsupported) Tcl8.3 core * unix/README: clarified usage of the CONFIG file * win/vc: adjusted MSVC files for changes introduced by TEA3 2004-12-18 Zoran Vasiljevic **** COMPATIBILITY: Dropped support for Tcl8.3 **** * aclocal.m4: Adjusted for TEA3 * Makefile.in: * configure.in: * pkgIndex.tcl.in: * configure: Rebuild with autoconf 2.59 * tests/all.tcl: Removed extra handling for Tcl 8.3 * tests/thread.tcl: since we do not support 8.3 any more * generic/psGdbm.c: * generic/threadCmd.c: * generic/threadSvCmd.c: * doc/thread.man: Updated docs for the 2.6 release * doc/tpool.man: * doc/tsv.man: * doc/ttrace.man: 2004-11-27 Zoran Vasiljevic * generic/threadPoolCmd.c: Fixed race condition which resulted in blocking at pool creation with high -minworkers threads. This fixes the Tcl Bug #933975. 2004-11-25 Zoran Vasiljevic * tests/thread.tcl: Disabled all tests handling channel transfer for Windows ports until core is capable of handling this correctly. * generic/threadSpCmd.c: Fixed segmentation problems observed on Windows ports and related to notification of an uninitialized condition variable(s). This closes Bug #1051068 (wrongly posted under Tcl Patches at SF). * doc/thread.man: Fixed mutex/condvar code example. Thanks to Gustaf Neumann of XOTcl for the tip. 2004-10-21 Andreas Kupries * tests/thread.test: Added two tests checking the working of fileevents after a pipe channel has been transfered. The second has to fail for any core where TIP #218 is not applied, because the incoming alert is directed to the wrong thread for event processing. 2004-10-20 Zoran Vasiljevic * generic/threadCmd.c (ThreadSetResult): adjusted handling of interp result to accomodate for recent changes in Tcl core. This closes Tcl Bug# 1050490. 2004-10-19 Andreas Kupries * generic/threadSvCmd.c: Added a prototype for SvObjDispatchObjCmd. Prevented compilation of debug variant on Windows due to warning as error. * tests/thread.test: Added more tests transfering channels between threads for in-core drivers. 2004-10-18 Andreas Kupries * generic/threadCmd.c (ThreadErrorProc): Added code to explicitly initialize the field 'interp' in ThreadSendData. This was ok (NULL) for a regular build, but when build with symbols the guard pattern forced a crash in test thread-16.2. * tests/thread.test: Duplicate test id thread-16.1 renamed to thread-16.2. 2004-08-14 Zoran Vasiljevic * generic/threadPoolCmd.c: fixed broken parsing of pool handles. Pool handles are now generated in the same format as thread handles. * generic/threadCmd.c: thread handles are now cased to (void*) and sprint/sscanf calls are used to generate thread handles. This concludes the effort of correcting broken handles on 64-bit machines since the problem was actually in Tcl itself, rather than here. 2004-07-21 Zoran Vasiljevic * generic/tclThread.h: corrected namespace prefix for AOLserver 4.x or higher, since namespaced commands are now supported. * generic/threadCmd.c: allows for re-initializing of package commands for AOLserver 4.x (or higheri) interpreters. This way we assure to have correct set of commands even if nobody loaded the package on server startup. Also, thread handles returned by the package now have the form: "tid" in (yet another) attempt to rectify problems found on Cray computers. * generic/threadPoolCmd.c: adjusted handles of the pools to match ones of threads (see above). 2004-07-21 Zoran Vasiljevic * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * generic/threadPoolCmd.c: fixed result list corruption in TpoolCancelObjCmd. 2003-07-27 Zoran Vasiljevic * 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 * 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 * generic/threadCmd.c: sets the name of the new thread to "-tclthread-" when compiled for AOLserver 2003-04-29 Zoran Vasiljevic 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 * 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 * 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 * 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 * 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 * generic/threadCmd.c: fixed ThreadSetResult to correctly initialize all elements of the result structure. 2003-02-08 Zoran Vasiljevic * 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 * 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 * generic/threadCmd.c: fixed reference to errorInfo when reporting error from the passed script. 2003-01-21 Mo DeJong * configure: Regenerate to include recent fixes for mingw build support in tclconfig module. 2002-12-18 Zoran Vasiljevic * README: added some AOLserver info * tcl/tpool/tpool.tcl: added missing tpool::names command 2002-12-14 Zoran Vasiljevic * doc/*: finished docs for the 2.5 release 2002-12-09 Zoran Vasiljevic * 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 * configure.in * configure * Makefile.in * aolserver.m4: added support for compilation under AOLserver as loadable module. 2002-12-06 Zoran Vasiljevic * 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 * 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 * 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 * tcl/phttpd/phttpd.tcl: added raw file; no thread support * tcl/cmdsrv/cmdsrv.tcl: first working version 2002-11-24 Zoran Vasiljevic * 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 * 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 * 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 for the correction. 2002-10-23 Zoran Vasiljevic * generic/threadCmd.c: added handling of background errors while doing an async callback. 2002-10-20 Zoran Vasiljevic * 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 * 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 * threadCmd.c: fixed potential memory corruption when releasing preserved interpreter. [Tcl bug 599290] 2002-08-19 Zoran Vasiljevic * generic/threadSvCmd.c: we now properly invalidate duped object string rep if the internal rep has been regenerated. 2002-08-18 Zoran Vasiljevic * 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 * 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 * 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 * 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 * threadCmd.c: added some macros to simplify adding and removing result structure in and out of the corresponding lists 2002-07-18 Zoran Vasiljevic * 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 * 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 * generic/threadSvCmd.s: fixed handling of string rep in shared var object duplicator 2002-07-09 Zoran Vasiljevic * README: added this file * license.terms: added this file 2002-07-05 Zoran Vasiljevic * tclconfig/tcl.m4: fixed reference to MINGW so we can compile w/o MSVC under windows. 2002-07-03 Zoran Vasiljevic * generic/threadSvCmd.c: simplified object duplicator 2002-06-17 Zoran Vasiljevic * 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 * generic/threadCmd.c: added some typecasts to satisfy Windows * generic/threadSvCmd.h: added some typecasts to satisfy Windows 2002-05-04 Zoran Vasiljevic * generic/threadSvCmd.c: removed errant reference to (still not) supported shared dictionary and shared keylist datatypes. 2002-04-27 Zoran Vasiljevic * 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 * 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 * 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 * Makefile.in (install-lib-binaries): ensure that binary files are installed with executable bit set (use INSTALL_PROGRAM) 2002-03-28 Jeff Hobbs * 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 * 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 * 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 * 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 * 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 * 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 * generic/threadCmd.c: fixed thread::preserve glitch. We never actually did bump the reservation counter by a silly mistake. 2002-02-12 Zoran Vasiljevic * 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 * 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 * 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 * 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 * 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 * generic/threadCmd.c: fixed multiple async reporting of error events (thanks Jean-Luc Fontaine for the tip) 2002-01-02 Zoran Vasiljevic * 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 * 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 * 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 -=[ Official 2.2 Tagged and cut. ]=- 2001-05-27 David Gravereaux * tests/thread.test: fixed small typo in comments. 2001-08-03 Jeff Hobbs * 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 * configure: * configure.in: * Makefile.in: Added package versions to the compile flags. [bug #421246] 2001-04-28 David Gravereaux * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 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 * Restored Andreas' changes for transferring sockets. 2000-05-16 Brent Welch * 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 * 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 * 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 * win/vc/config.rc, Makefile.vc: Fixes from David Gravereaux 2000-04-18 Brent Welch * Makefile.in: Fixes for make install 2000-04-17 Brent Welch * generic/threadCmd.c Added Tcl_CreateThreadType and TCL_RETURN_THREAD_TYPE macros for declaring the NewThread callback proc. 2000-04-11 Brent Welch * Picked up minor changes from David Gravereaux * for compilation on windows with his alternate project files. 2000-04-10 Brent Welch * 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 * Updated to compile against 8.3.1 export thread APIs * Added Windows makefiles 2000-03-27 Brent Welch (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
