* 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].

* condvar.c (pthread_cond_init): fix possible uninitialised use of cv. Sun Mar 14 21:01:59 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * condvar.c (pthread_cond_destroy): don't do full cleanup if static initialised cv has never been used. (cond_timedwait): check result of auto-initialisation. tests/ChangeLog Mon Mar 15 00:17:55 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * mutex1.c: only test mutex init and destroy; add assertions. * count1.c: raise number of spawned threads to 60 (appears to be the limit under Win98). Sun Mar 14 21:31:02 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * test.h (assert): add assertion trace option. Use: "#define ASSERT_TRACE 1" to turn it on, "#define ASSERT_TRACE 0" to turn it off (default). * condvar3.c (main): add more assertions. * condvar4.c (main): add more assertions. * condvar1.c (main): add more assertions.

* Makefile: Some refinement. * *.c: More exhaustive checking through assertions; clean up; add some more tests.

* README: Update. * Makefile: New file. Run all tests automatically. Primitive tests are run first; more complex tests are run last. * count1.c: New test. Validate the thread count. * exit2.c: Perform a simpler test. * exit3.c: New test. Replaces exit2.c, since exit2.c needs to perform simpler checking first. * create1.c: Update to use the new testsuite exiting convention. * equal1.c: Likewise. * mutex1.c: Likewise. * mutex2.c: Likewise. * once1.c: Likewise. * self2.c: Likewise. * self3.c: Likewise. * tsd1.c: Likewise.

* tests/mutex2.c: Test pthread_mutex_trylock(). Passes. * tests/mutex1.c (main): Eliminate warning.

* tests/mutex1.c: New basic test for mutex functions (it passes).
