* cleanup.c (pthread_pop_cleanup): Remove _pthread prefix from __except and catch keywords; implement.h now simply undefines _pthread__except and _pthread_catch if defined; VC++ was not textually substituting _pthread_catch etc back to catch as it was redefined; the reason for using the prefixed version was to make it clear that it was not using the pthread.h redefined catch keyword. * private.c (_pthread_threadStart): Ditto. (_pthread_callUserDestroyRoutines): Ditto. * implement.h (_pthread__except): Remove #define. (_pthread_catch): Remove #define. * GNUmakefile (pthread.a): New target to build libpthread32.a from pthread.dll using dlltool. * buildlib.bat: Duplicate cl commands with args to build C++ EH version of pthread.dll; use of .bat files is redundant now that nmake compatible Makefile is included; used as a kludge only now. * Makefile: Localise some macros and fix up the clean: target to extend it and work properly. * CONTRIBUTORS: Add contributors. * ANNOUNCE: Updated. * README: Updated. tests/ChangeLog: 2000-08-10 Ross Johnson <rpj@special.ise.canberra.edu.au> * eyal1.c (main): Change implicit cast to explicit cast when passing "print_server" function pointer; G++ no longer allows implicit func parameter casts. * cleanup1.c: Remove unused "waitLock". (main): Fix implicit parameter cast. * cancel2.c (main): Fix implicit parameter cast. * cancel4.c (main): Fix implicit parameter cast. * cancel3.c (main): Fix implicit parameter cast. * GNUmakefile: Renamed from Makefile; Add missing cancel1 and cancel2 test targets. * Makefile: Converted for use with MS nmake.

* pthread.h: Remove #warning - VC++ doesn't accept it. 2000-08-05 Ross Johnson <rpj@special.ise.canberra.edu.au> * pthread.h (PtW32CatchAll): Add macro. When compiling applications using VC++ with C++ EH rather than SEH 'PtW32CatchAll' must be used in place of any 'catch( ... )' if the application wants pthread cancelation or pthread_exit() to work. 2000-08-03 Ross Johnson <rpj@special.ise.canberra.edu.au> * pthread.h: Add a base class Pthread_exception for library internal exceptions and change the "catch" re-define macro to use it. 2000-08-02 Ross Johnson <rpj@special.ise.canberra.edu.au> * GNUmakefile (CFLAGS): Add -mthreads. Add new targets to generate cpp and asm output. * sync.c (pthread_join): Remove dead code. tests: 2000-08-06 Ross Johnson <rpj@special.ise.canberra.edu.au> * ccl.bat: Add /nologo to remove extraneous output. * exception1.c (exceptionedThread): Init 'dummy'; put expression into if condition to prevent optimising away; remove unused variable. * cancel4.c (mythread): Cast return value to avoid warnings. * cancel2.c (mythread): Missing #endif. * condvar9.c (mythread): Cast return value to avoid warnings. * condvar8.c (mythread): Cast return value to avoid warnings. * condvar7.c (mythread): Cast return value to avoid warnings. * cleanup3.c (mythread): Cast return value to avoid warnings. * cleanup2.c (mythread): Cast return value to avoid warnings. * cleanup1.c (mythread): Cast return value to avoid warnings. * condvar5.c (mythread): Cast return value to avoid warnings. * condvar3.c (mythread): Cast return value to avoid warnings. * condvar6.c (mythread): Cast return value to avoid warnings. * condvar4.c (mythread): Cast return value to avoid warnings. 2000-08-05 Ross Johnson <rpj@special.ise.canberra.edu.au> * cancel2.c: Use PtW32CatchAll macro if defined. * exception1.c: Use PtW32CatchAll macro if defined. 2000-08-02 Ross Johnson <rpj@special.ise.canberra.edu.au> * tsd1.c: Fix typecasts of &result [g++ is now very fussy]. * test.h (assert): Return 0's explicitly to allay g++ errors. * join2.c: Add explicit typecasts. * join1.c: Add explicit typecasts. * join0.c: Add explicit typecasts. * eyal1.c: Add explicit typecasts. * count1.c (main): Add type cast to remove g++ parse warning [gcc-2.95.2 seems to have tightened up on this]. * Makefile (GLANG): Use c++ explicitly. Remove MSVC sections (was commented out). Add target to generate cpp output.

* sched.c (sched_get_priority_max): Handle different WinCE and Win32 priority values together. (sched_get_priority_min): Ditto. - Tristan Savatier <tristan@mpegtv.com> * create.c (pthread_create): Force new threads to wait until pthread_create has the new thread's handle; we also retain a local copy of the handle for internal use until pthread_create returns. * private.c (_pthread_threadStart): Initialise ei[]. (_pthread_threadStart): When beginthread is used to start the thread, force waiting until the creator thread had the thread handle. * cancel.c (_pthread_cancel_thread): Include context switch code for defined(_X86_) environments in addition to _M_IX86. * rwlock.c (pthread_rwlock_destroy): Assignment changed to avoid compiler warning. * private.c (_pthread_get_exception_services_code): Cast NULL return value to avoid compiler warning. * cleanup.c (pthread_pop_cleanup): Initialise "cleanup" variable to avoid compiler warnings. * misc.c (_pthread_new): Change "new" variable to "t" to avoid confusion with the C++ keyword of the same name. * condvar.c (cond_wait_cleanup): Initialise lastWaiter variable. (cond_timedwait): Remove unused local variables. to avoid compiler warnings. * dll.c (dllMain): Remove 2000-07-21 change - problem appears to be in pthread_create(). 2000-07-22 Ross Johnson <rpj@special.ise.canberra.edu.au> * tsd.c (pthread_key_create): If a destructor was given and the pthread_mutex_init failed, then would try to reference a NULL pointer (*key); eliminate this section of code by using a dynamically initialised mutex (PTHREAD_MUTEX_INITIALIZER). * tsd.c (pthread_setspecific): Return an error if unable to set the value; simplify cryptic conditional. * tsd.c (pthread_key_delete): Locking threadsLock relied on mutex_lock returning an error if the key has no destructor. ThreadsLock is only initialised if the key has a destructor. Making this mutex a static could reduce the number of mutexes used by an application since it is actually created only at first use and it's often destroyed soon after. 2000-07-22 Ross Johnson <rpj@special.ise.canberra.edu.au> * FAQ: Added Q5 and Q6. tests/ChangeLog: 2000-07-25 Ross Johnson <rpj@special.ise.canberra.edu.au> * runtest.bat: modified to work under W98. * runall.bat: Add new tests; modified to work under W98. It was ok under NT. * Makefile: Add new tests. * exception1.c: New; Test passing exceptions back to the application and retaining library internal exceptions. * join0.c: New; Test a single join.

* dll.c (dllMain): Remove 2000-07-21 change - problem appears to be in pthread_create(). 2000-07-21 Ross Johnson <rpj@setup1.ise.canberra.edu.au> * create.c (pthread_create): Set threadH to 0 (zero) everywhere. Some assignments were using NULL. Maybe it should be NULL everywhere - need to check. (I know they are nearly always the same thing - but not by definition.) * dll.c: Include resource leakage work-around. This is a partial FIXME which doesn't stop all leakage. The real problem needs to be found and fixed. - "David Baggett" <dmb@itasoftware.com> * misc.c (pthread_self): Try to catch NULL thread handles at the point where they might be generated, even though they should always be valid at this point. * tsd.c (pthread_setspecific): return an error value if pthread_self() returns NULL. * sync.c (pthread_join): return an error value if pthread_self() returns NULL. * signal.c (pthread_sigmask): return an error value if pthread_self() returns NULL.
