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.

* 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.
2002-01-08Update docs.rpj
2002-01-07 * mutex.c (pthread_mutex_init): Remove criticalrpj
section calls. (pthread_mutex_destroy): Likewise. (pthread_mutex_unlock): Likewise. (pthread_mutex_trylock): Likewise; recursive mutexes now increment the lock count rather than return EBUSY; errorcheck mutexes return EDEADLCK rather than EBUSY. This behaviour is consistent with the Solaris pthreads implementation. * implement.h (pthread_mutex_t_): Remove critical section element - no longer needed.
2002-01-04 * attr.c (pthread_attr_setscope): Add more errorrpj
checking and actually store the scope value even though it's not really necessary. (pthread_attr_getscope): Return stored value. * implement.h (pthread_attr_t_): Add new scope element. * ANNOUNCE: Fix out of date comment next to pthread_attr_setscope in conformance section.
2001-07-18 * rwlock.c (pthread_rwlock_wrlock): Is allowed to berpj
a cancelation point; re-enable deferred cancelability around the CV call.

Contributed by - Alexander Terekhov. * condvar.c: Fixed lost signal bug reported by Timur Aydin (taydin@snet.net). [RPJ (me) didn't translate the original algorithm correctly.] * semaphore.c: Added sem_post_multiple; this is a useful routine, but it doesn't appear to be standard. For now it's not an exported function.
2001-07-012001-06-25 Ross Johnson <rpj@setup1.ise.canberra.edu.au>rpj
* create.c (pthread_create): Add priority inheritance attributes. * mutex.c (pthread_mutex_lock): Remove some overhead for PTHREAD_MUTEX_NORMAL mutex types. Specifically, avoid calling pthread_self() and pthread_equal() to check/set the mutex owner. Introduce a new pseudo owner for this type. Test results suggest increases in speed of up to 90% for non-blocking locks. This is the default type of mutex used internally by other synchronising objects, ie. condition variables and read-write locks. The test rwlock7.c shows about a 30-35% speed increase over snapshot 2001-06-06. The price of this is that the application developer must ensure correct behaviour, or explicitly set the mutex to a safer type such as PTHREAD_MUTEX_ERRORCHECK. For example, PTHREAD_MUTEX_NORMAL (or PTHREAD_MUTEX_DEFAULT) type mutexes will not return an error if a thread which is not the owner calls pthread_mutex_unlock. The call will succeed in unlocking the mutex if it is currently locked, but a subsequent unlock by the true owner will then fail with EPERM. This is however consistent with some other implementations. (pthread_mutex_unlock): Likewise. (pthread_mutex_trylock): Likewise. (pthread_mutex_destroy): Likewise. * attr.c (pthread_attr_init): PTHREAD_EXPLICIT_SCHED is the default inheritance attribute; THREAD_PRIORITY_NORMAL is the default priority for new threads. * sched.c (pthread_attr_setschedpolicy): Added routine. (pthread_attr_getschedpolicy): Added routine. (pthread_attr_setinheritsched): Added routine. (pthread_attr_getinheritsched): Added routine. * pthread.h (sched_rr_set_interval): Added as a macro; returns -1 with errno set to ENOSYS. 2001-06-23 Ross Johnson <rpj@setup1.ise.canberra.edu.au> *sched.c (pthread_attr_setschedparam): Add priority range check. (sched_setscheduler): New function; checks for a valid pid and policy; checks for permission to set information in the target process; expects pid to be a Win32 process ID, not a process handle; the only scheduler policy allowed is SCHED_OTHER. (sched_getscheduler): Likewise, but checks for permission to query. * pthread.h (SCHED_*): Moved to sched.h as defined in the POSIX standard. * sched.h (SCHED_*): Moved from pthread.h. (pid_t): Defined if necessary. (sched_setscheduler): Defined. (sched_getscheduler): Defined. * pthread.def (sched_setscheduler): Exported. (sched_getscheduler): Likewise. 2001-06-23 Ross Johnson <rpj@setup1.ise.canberra.edu.au> Contributed by - Ralf Brese <Ralf.Brese@pdb4.siemens.de> * create.c (pthread_create): Set thread priority from thread attributes.

* 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].

* cancel.c (pthread_cancel): Must get "self" through calling pthread_self() which will ensure a POSIX thread struct is built for non-POSIX threads; return an error if this fails - Ollie Leahy <ollie@mpt.ie> (pthread_setcancelstate): Likewise.

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.

(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.
