2001-07-11Fixed cast; tests passed.rpj
2001-07-10Updated.rpj
2001-07-10Untested revamp of barrier.c.rpj
* barrier.c: Still more revamping. The exclusive access mutex isn't really needed so it has been removed and replaced by an InterlockedDecrement(). nSerial has been removed. iStep is now dual-purpose. The process shared attribute is now stored in the barrier struct. * implement.h (pthread_barrier_t_): Lost some/gained one elements. * private.c (ptw32_threadStart): Removed some comments.
2001-07-09 * barrier.c: Revamped to fix the race condition. Two alternatingrpj
semaphores are used instead of the PulseEvent. Also improved overall throughput by returning PTHREAD_BARRIER_SERIAL_THREAD to the first waking thread. * implement.h (pthread_barrier_t_): Revamped.
2001-07-08Barriers fixed and tested more extensively.rpj
* barrier.c: Fix several bugs in all routines. Now passes tests/barrier5.c which is fairly rigorous. There is still a non-optimal work-around for a race condition between the barrier breeched event signal and event wait. Basically the last (signalling) thread to hit the barrier yields to allow any other threads, which may have lost the race, to complete. tests/ChangeLog: * barrier3.c: Fixed. * barrier4.c: Fixed. * barrier5.c: New; proves that all threads in the group reaching the barrier wait and then resume together. Repeats the test using groups of 1 to 16 threads. Each group of threads must negotiate a large number of barriers (10000). * spin4.c: Fixed. * test.h (error_string): Modified the success (0) value.

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.

Contributed by - David Korn <dgk@research.att.com> * dll.c: Added changes necessary to work with UWIN. * create.c: Likewise. * pthread.h: Likewise. * misc.c: Likewise. * exit.c: Likewise. * private.c: Likewise. * implement.h: Likewise. There is some room at the start of struct pthread_t_ to implement the signal semantics in UWIN's posix.dll although this is not yet complete. * Nmakefile: Compatible with UWIN's Nmake utility. * Nmakefile.tests: Likewise - for running the tests.
2001-06-11 * semaphore.h (sem_t): Fixed for compile and test.rpj
* implement.h (sem_t_): Likewise. * semaphore.c: Likewise. * private.c (ptw32_sem_timedwait): Updated to use new opaque sem_t. tests/ * mutex5.c: Insert inert change to quell compiler warnings. * condvar3_2.c: Remove unused variable.
2001-06-07 * semaphore.h (sem_t): Is now an opaque pointer;rpj
moved actual definition to implement.h. * implement.h (sem_t_): Move here from semaphore.h; was the definition of sem_t. * semaphore.c: Wherever necessary, changed use of sem from that of a pointer to a pointer-pointer; added extra checks for a valid sem_t; NULL sem_t when it is destroyed; added extra checks when creating and destroying sem_t elements in the NEED_SEM code branches; changed from using a pthread_mutex_t ((*sem)->mutex) to CRITICAL_SECTION ((*sem)->sem_lock_cs) in NEED_SEM branches for access serialisation.

* 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].

(ptw32_threadStart): Cleanup detached threads early in case the library is statically linked.

This requires also keeping count of recursive locks ourselves rather than leaving it to Win32 since we need to know when to NULL the thread owner when the mutex is unlocked. (pthread_mutex_trylock): Likewise. (pthread_mutex_unlock): Check that the calling thread owns the mutex, decrement the recursive lock count, and NULL the owner if zero.

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.
