conditional compilation; refinements; bug fixes. See the ChangeLog.

Remove unused autoconf files;
Add the file COPYING, which describes the pthread-win32 license
relative to the FSF LGPL.

* 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.

* 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].

* 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.

* 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.

* 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).
