404	* attr.c (pthread_attr_setscope): Fix struct pointer * attr.c (pthread_attr_setscope): Fix struct pointer indirection error introduced 2002-01-04. (pthread_attr_getscope): Likewise. * pthread.dsp (SOURCE): Add missing source files. ./tests/: * exception3.c (main): Shorten wait time. * mutex7.c: New test. * mutex7n.c: New test. * mutex7e.c: New test. * mutex7r.c: New test. * mutex6.c: Modified to avoid leaving the locked mutex around on exit.	rpj		22 years ago
400	* attr.c (pthread_attr_setscope): Add more error * attr.c (pthread_attr_setscope): Add more error 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 * ANNOUNCE: Fix out of date comment next to pthread_attr_setscope in conformance section.	rpj		22 years ago
397	Include an interim complete Copyright notice in each source ... Include an interim complete Copyright notice in each source file; Remove unused autoconf files; Add the file COPYING, which describes the pthread-win32 license relative to the FSF LGPL.	rpj		22 years ago
392	* attr.c (pthread_attr_setstacksize): Quell warning * attr.c (pthread_attr_setstacksize): Quell warning from LCC by conditionally compiling the stacksize validity check. LCC correctly warns that the condition (stacksize < PTHREAD_STACK_MIN) is suspicious because STACK_MIN is 0 and stacksize is of type size_t (or unsigned int).	rpj		22 years ago
375	Barriers fixed and tested more extensively. Barriers fixed and tested more extensively. * 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.	rpj		22 years ago
364	2001-06-25 Ross Johnson <rpj@setup1.ise.canberra.edu.au> 2001-06-25 Ross Johnson <rpj@setup1.ise.canberra.edu.au> * 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.	rpj		22 years ago
349	2001-05-30 Ross Johnson <rpj@setup1.ise.canberra.edu.au> 2001-05-30 Ross Johnson <rpj@setup1.ise.canberra.edu.au> * 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].	rpj		22 years ago
329	2000-08-18 Ross Johnson <rpj@setup1.ise.canberra.edu.au> 2000-08-18 Ross Johnson <rpj@setup1.ise.canberra.edu.au> * 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.	rpj		23 years ago
315	2000-07-25 Ross Johnson <rpj@special.ise.canberra.edu.au> 2000-07-25 Ross Johnson <rpj@special.ise.canberra.edu.au> * 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.	rpj		23 years ago
