2002-02-03Change #pragma inline_depth(8) to use empty () for default value.rpj
2002-02-02 * cancel.c: Rearranged some code and introduced checksrpj
to disable cancelation at the start of a thread's cancelation run to prevent double cancelation. The main problem arises if a thread is canceling and then receives a subsequent async cancel request. * private.c: Likewise. * condvar.c: Place pragmas around cleanup_push/pop to turn off inline optimisation (/Obn where n>0 - MSVC only). Various optimisation switches in MSVC turn this on, which interferes with the way that cleanup handlers are run in C++ EH and SEH code. Application code compiled with inline optimisation must also wrap cleanup_push/pop blocks with the pragmas, e.g. #pragma inline_depth(0) pthread_cleanup_push(...) ... pthread_cleanup_pop(...) #pragma inline_depth(8) * rwlock.c: Likewise. * mutex.c: Remove attempts to inline some functions. * signal.c: Modify misleading comment. tests/ * mutex8: New test. * mutex8n: New test. * mutex8e: New test. * mutex8r: New test. * cancel6a: New test. * cancel6d: New test. * cleanup0.c: Add pragmas for inline optimisation control. * cleanup1.c: Add pragmas for inline optimisation control. * cleanup2.c: Add pragmas for inline optimisation control. * cleanup3.c: Add pragmas for inline optimisation control. * condvar7.c: Add pragmas for inline optimisation control. * condvar8.c: Add pragmas for inline optimisation control. * condvar9.c: Add pragmas for inline optimisation control.

2000-12-29 Ross Johnson <rpj@special.ise.canberra.edu.au> * Makefile: Back-out "for" loops which don't work. * GNUmakefile: Remove the fake.a target; add the "realclean" target; don't remove built libs under the "clean" target. * config.h: Add a guard against multiple inclusion. * semaphore.h: Add some defines from config.h to make semaphore.h independent of config.h when building apps. * pthread.h (_errno): Back-out previous fix until we know how to fix it properly. * implement.h (lockCount): Add missing element to pthread_mutex_t_. * sync.c (pthread_join): Spelling fix in comment. * private.c (ptw32_threadStart): Reset original termination function (C++). (ptw32_threadStart): Cleanup detached threads early in case the library is statically linked. (ptw32_callUserDestroyRoutines): Remove [SEH] __try block from destructor call so that unhandled exceptions will be passed through to the system; call terminate() from [C++] try block for the same reason. * tsd.c (pthread_getspecific): Add comment. * mutex.c (pthread_mutex_init): Initialise new elements in pthread_mutex_t. (pthread_mutex_unlock): Invert "pthread_equal()" test. 2000-12-28 Ross Johnson <rpj@special.ise.canberra.edu.au> * semaphore.c (mode_t): Use ifndef HAVE_MODE_T to include definition. * config.h.in (HAVE_MODE_T): Added. (_UWIN): Start adding defines for the UWIN package. ./tests/ChangeLog: 2000-12-29 Ross Johnson <rpj@special.ise.canberra.edu.au> * GNUmakefile: Add mutex4 test; ensure libpthreadw32.a is removed for "clean" target. * Makefile: Add mutex4 test. * exception3.c: Remove SEH code; automatically pass the test under SEH (which is an N/A environment). * mutex4.c: New test. * eyal1.c (do_work_unit): Add a dummy "if" to force the optimiser to retain code; reduce thread work loads. * condvar8.c (main): Add an additional "assert" for debugging; increase pthread_cond_signal timeout.

* errno.c: Add _MD precompile condition; thus far had no effect when using /MD compile option but I thnk it should be there. * exit.c: Add __cplusplus to various #if lines; was compiling SEH code even when VC++ had C++ compile options. * private.c: ditto. * create.c (pthread_create): Add PT_STDCALL macro to function pointer arg in _beginthread(). * pthread.h: PT_STDCALL really does need to be defined in both this and impliment.h; don't set it to __cdecl - this macro is only used to extend function pointer casting for functions that will be passed as parameters. (~PThreadCleanup): add cast and group expression. (_errno): Add _MD compile conditional. (PtW32NoCatchWarn): Change pragma message. * implement.h: Move and change PT_STDCALL define. * need_errno.h: Add _MD to compilation conditional. * GNUmakefile: Substantial rewrite for new naming convention; set for nil optimisation (turn it up when we have a working library build; add target "fake.a" to build a libpthreadw32.a from the VC++ built DLL pthreadVCE.dll. * pthread.def (LIBRARY): Don't specify in the .def file - it is specified on the linker command line since we now use the same .def file for variously named .dlls. * Makefile: Substantial rewrite for new naming convention; default nmake target only issues a help message; run nmake with specific target corresponding to the EH scheme being used. * README: Update information; add naming convention explanation. * ANNOUNCE: Update information. 2000-08-12 Ross Johnson <rpj@special.ise.canberra.edu.au> * pthread.h: Add compile-time message when using MSC_VER compiler and C++ EH to warn application programmers to use PtW32Catch instead of catch(...) if they want cancelation and pthread_exit to work. * implement.h: Remove #include <semaphore.h>; we use our own local semaphore.h. tests/ChangeLog: 2000-08-13 Ross Johnson <rpj@special.ise.canberra.edu.au> * condvar3.c: Minor change to eliminate compiler warning. * condvar4.c: ditto. * condvar5.c: ditto. * condvar6.c: ditto. * condvar7.c: ditto. * condvar8.c: ditto. * condvar9.c: ditto. * exit1.c: Function needed return statement. * cleanup1.c: Remove unnecessary printf arg. * cleanup2.c: Fix cast. * rwlock6.c: Fix casts. * exception1.c (PtW32CatchAll): Had the wrong name; fix casts. * cancel3.c: Remove unused waitLock variable. * GNUmakefile: Change library/dll naming; add new tests; general minor changes. * Makefile: Change library/dll naming; add targets for testing each of the two VC++ EH scheme versions; default target now issues help message; compile warnings now interpreted as errors to stop the make; add new tests; restructure to remove prerequisites needed otherwise. * README: Updated.

* 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.
