2002-03-02 * errno.c: Compiler directive was incorrectly including code.rpj
* pthread.h: Conditionally added some #defines from config.h needed when not building the library. e.g. NEED_ERRNO, NEED_SEM. (PTW32_DLLPORT): Now only defined if _DLL defined. (_errno): Compiler directive was incorrectly including prototype. * sched.h: Conditionally added some #defines from config.h needed when not building the library. * semaphore.h: Replace an instance of NEED_SEM that should have been NEED_ERRNO. This change currently has nil effect. * GNUmakefile: Correct some recent changes. * Makefile: Add rule to generate pre-processor output.
2002-02-27 * exception3.c (terminateFunction): For MSVC++, callrpj
exit() rather than pthread_exit().

* mutex.c (pthread_mutex_timedlock): New function suggested by Alexander Terekhov. The logic required to implement this properly came from Alexander, with some collaboration with Thomas Pfaff. (pthread_mutex_unlock): Wrap the waiters check and sema post in a critical section to prevent a race with pthread_mutex_timedlock. (ptw32_timed_semwait): New function; returns a special result if the absolute timeout parameter represents a time already passed when called; used by pthread_mutex_timedwait(). Have deliberately not reused the name "ptw32_sem_timedwait" because they are not the same routine. * condvar.c (ptw32_cond_timedwait): Use the new sem_timedwait() instead of ptw32_sem_timedwait(), which now has a different function. See previous. * implement.h: Remove prototype for ptw32_sem_timedwait. See next. (pthread_mutex_t_): Add critical section element for access to lock_idx during mutex post-timeout processing. * semaphore.h (sem_timedwait): See next. * semaphore.c (sem_timedwait): See next. * private.c (ptw32_sem_timedwait): Move to semaphore.c and rename as sem_timedwait(). 2002-01-18 Ross Johnson <rpj@special.ise.canberra.edu.au> * sync.c (pthread_join): Was getting the exit code from the calling thread rather than the joined thread if defined(__MINGW32__) && !defined(__MSVCRT__). 2002-01-15 Ross Johnson <rpj@special.ise.canberra.edu.au> * pthread.h: Unless the build explicitly defines __CLEANUP_SEH, __CLEANUP_CXX, or __CLEANUP_C, then the build defaults to __CLEANUP_C style cleanup. This style uses setjmp/longjmp in the cancelation and thread exit implementations and therefore won't do stack unwinding if linked to applications that have it (e.g. C++ apps). This is currently consistent with most/all commercial Unix POSIX threads implementations. * spin.c (pthread_spin_init): Edit renamed function call. * nonportable.c (pthread_num_processors_np): New. (pthread_getprocessors_np): Renamed to ptw32_getprocessors and moved to private.c. * private.c (pthread_getprocessors): Moved here from nonportable.c. * pthread.def (pthread_getprocessors_np): Removed from export list. * rwlock.c (pthread_rwlockattr_init): New. (pthread_rwlockattr_destroy): New. (pthread_rwlockattr_getpshared): New. (pthread_rwlockattr_setpshared): New.
2001-10-25 * GNUmakefile (libwsock32): Add to linker flags forrpj
WSAGetLastError() and WSASetLastError(). * Makefile (wsock32.lib): Likewise. * create.c: Minor mostly inert changes. * implement.h (PTW32_MAX): Move into here and renamed from sched.h. (PTW32_MIN): Likewise. * GNUmakefile (TEST_ICE): Define if testing internal implementation of InterlockedCompareExchange. * Makefile (TEST_ICE): Likewise. * private.c (TEST_ICE): Likewise.

2001-05-312001-05-30 Ross Johnson <rpj@setup1.ise.canberra.edu.au>rpj
* pthread.h (rand_r): Fake using _seed argument to quell compiler warning (compiler should optimise this away later). * GNUmakefile (OPT): Leave symbolic information out of the library and increase optimisation level - for smaller faster prebuilt dlls. 2001-05-29 Ross Johnson <rpj@setup1.ise.canberra.edu.au> Contributed by - Milan Gardian <Milan.Gardian@LEIBINGER.com> * Makefile: fix typo. * pthreads.h: Fix problems with stdcall/cdecl conventions, in particular remove the need for PT_STDCALL everywhere; remove warning supression. * (errno): Fix the longstanding "inconsistent dll linkage" problem with errno; now also works with /MD debugging libs - warnings emerged when compiling pthreads library with /MD (or /MDd) compiler switch, instead of /MT (or /MTd) (i.e. when compiling pthreads using Multithreaded DLL CRT instead of Multithreaded statically linked CRT). * create.c (pthread_create): Likewise; fix typo. * private.c (ptw32_threadStart): Eliminate use of terminate() which doesn't throw exceptions. * Remove unnecessary #includes from a number of modules - [I had to #include malloc.h in implement.h for gcc - rpj]. 2001-05-29 Ross Johnson <rpj@setup1.ise.canberra.edu.au> Contributed by - Thomas Pfaff <tpfaff@gmx.net> * pthread.h (PTHREAD_MUTEX_DEFAULT): New; equivalent to PTHREAD_MUTEX_DEFAULT_NP. * (PTHREAD_MUTEX_NORMAL): Similarly. * (PTHREAD_MUTEX_ERRORCHECK): Similarly. * (PTHREAD_MUTEX_RECURSIVE): Similarly. * (pthread_mutex_setdefaultkind_np): New; Linux compatibility stub for pthread_mutexattr_settype. * (pthread_mutexattr_getkind_np): New; Linux compatibility stub for pthread_mutexattr_gettype. * mutex.c (pthread_mutexattr_settype): New; allow the following types of mutex: PTHREAD_MUTEX_DEFAULT_NP PTHREAD_MUTEX_NORMAL_NP PTHREAD_MUTEX_ERRORCHECK_NP PTHREAD_MUTEX_RECURSIVE_NP * Note that PTHREAD_MUTEX_DEFAULT is equivalent to PTHREAD_MUTEX_NORMAL - ie. mutexes should no longer be recursive by default, and a thread will deadlock if it tries to relock a mutex it already owns. This is inline with other pthreads implementations. * (pthread_mutex_lock): Process the lock request according to the mutex type. * (pthread_mutex_init): Eliminate use of Win32 mutexes as the basis of POSIX mutexes - instead, a combination of one critical section and one semaphore are used in conjunction with Win32 Interlocked* routines. * (pthread_mutex_destroy): Likewise. * (pthread_mutex_lock): Likewise. * (pthread_mutex_trylock): Likewise. * (pthread_mutex_unlock): Likewise. * Use longjmp/setjmp to implement cancelation when building the library using a C compiler which doesn't support exceptions, e.g. gcc -x c (note that gcc -x c++ uses exceptions). * Also fixed some of the same typos and eliminated PT_STDCALL as Milan Gardian's patches above. 2001-02-07 Ross Johnson <rpj@special.ise.canberra.edu.au> Contributed by - Alexander Terekhov <TEREKHOV@de.ibm.com> * rwlock.c: Revamped. * implement.h (pthread_rwlock_t_): Redefined. This implementation does not have reader/writer starvation problem. Rwlock attempts to behave more like a normal mutex with races and scheduling policy determining who is more important; It also supports recursive locking, has less synchronization overhead (no broadcasts at all, readers are not blocked on any condition variable) and seem to be faster than the current implementation [W98 appears to be approximately 15 percent faster at least - on top of speed increase from Thomas Pfaff's changes to mutex.c - rpj].
2000-12-29./ChangeLog:rpj
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.
2000-12-28./ChangeLog:rpj
2000-12-28 Ross Johnson <rpj@special.ise.canberra.edu.au> * private.c (ptw32_threadStart): Unhandled exceptions are now passed through to the system to deal with. This is consistent with normal Windows behaviour. C++ applications may use set_terminate() to override the default behaviour which is to call ptw32_terminate(). Ptw32_terminate() cleans up some POSIX thread stuff before calling the system default function which calls abort(). The users termination function should conform to standard C++ semantics which is to not return. It should exit the thread (call pthread_exit()) or exit the application. * private.c (ptw32_terminate): Added as the default set_terminate() function. It calls the system default function after cleaning up some POSIX thread stuff. * implement.h (ptw32_try_enter_critical_section): Move declaration. * global.c (ptw32_try_enter_critical_section): Moved from dll.c. * dll.c: Move process and thread attach/detach code into functions in nonportable.c. * nonportable.c (pthread_win32_process_attach_np): Process attach code from dll.c is now available to static linked applications. * nonportable.c (pthread_win32_process_detach_np): Likewise. * nonportable.c (pthread_win32_thread_attach_np): Likewise. * nonportable.c (pthread_win32_thread_detach_np): Likewise. * pthread.h: Add new non-portable prototypes for static linked applications. * GNUmakefile (OPT): Increase optimisation flag and remove debug info flag. * pthread.def: Add new non-portable exports for static linked applications. 2000-12-11 Ross Johnson <rpj@special.ise.canberra.edu.au> * FAQ: Update Answer 6 re getting a fully working Mingw32 built library. 2000-09-09 Ross Johnson <rpj@special.ise.canberra.edu.au> * pthread.h (ctime_r): Fix arg. ./tests/ChangeLog: 2000-12-28 Ross Johnson <rpj@special.ise.canberra.edu.au> * eyal1.c: Increase thread work loads. * exception2.c: New test. * exception3.c: New test. * Makefile: Add new tests exception2.c and exception3.c. * GNUmakefile: Likewise. 2000-12-11 Ross Johnson <rpj@special.ise.canberra.edu.au> * cleanup3.c: Remove unused variable. * cleanup2.c: Likewise. * exception1.c: Throw an exception rather than use a deliberate zero divide so that catch(...) will handle it under Mingw32. Mingw32 now builds the library correctly to pass all tests - see Thomas Pfaff's detailed instructions re needed changes to Mingw32 in the Pthreads-Win32 FAQ.

* Several: Fix typos from scripted edit session yesterday. * nonportable.c (pthread_mutexattr_setforcecs_np): Moved this function from mutex.c. (pthread_getw32threadhandle_np): New function to return the win32 thread handle that the POSIX thread is using. * mutex.c (pthread_mutexattr_setforcecs_np): Moved to new file "nonportable.c". * pthread.h (PTW32_BUILD): Only redefine __except and catch compiler keywords if we aren't building the library (ie. PTW32_BUILD is not defined) - this is safer than defining and then undefining if not building the library. * implement.h: Remove __except and catch undefines. * Makefile (CFLAGS): Define PTW32_BUILD. * GNUmakefile (CFLAGS): Define PTW32_BUILD. * All appropriate: Change Pthread_exception* to ptw32_exception* to be consistent with internal identifier naming. * private.c (ptw32_throw): New function to provide a generic exception throw for all internal exceptions and EH schemes. (ptw32_threadStart): pthread_exit() value is now returned via the thread structure exitStatus element. * exit.c (pthread_exit): pthread_exit() value is now returned via the thread structure exitStatus element. * cancel.c (ptw32_cancel_self): Now uses ptw32_throw. (pthread_setcancelstate): Ditto. (pthread_setcanceltype): Ditto. (pthread_testcancel): Ditto. (pthread_cancel): Ditto. * misc.c (CancelableWait): Ditto. * exit.c (pthread_exit): Ditto. * All applicable: Change PTW32_ prefix to PTW32_ prefix to remove leading underscores from private library identifiers.

* 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.

* 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.
