* global.c (_pthread_tsd_key_table): Add new global.
* implement.h (_pthread_tsd_key_t and struct _pthread_tsd_key):
Add.
(struct _pthread): Remove destructorstack.
* cleanup.c (_pthread_destructor_run_all): Rename from
_pthread_destructor_pop_all. The key destructor stack was made
global rather than per-thread. No longer removes destructor nodes
from the stack. Comments updated.

|
* condvar.c (cond_wait): Use POSIX, not Win32 mutex calls.
(pthread_cond_broadcast): Likewise.
(pthread_cond_signal): Likewise.
|
|
* pthread.def: Update. Some functions aren't available yet, others
are macros in <pthread.h>.
* tests/join.c: Remove; useless.
|
|
* pthread.def: New file for building the DLL.
|
|
* tests/self.c: Remove; rename to self1.c.
* tests/self1.c: This is the old self.c.
* tests/self2.c: New file. Test pthread_self() with a single
thread. Passes.
* tests/self3.c: New file. Test pthread_self() with a couple of
threads to ensure their thread IDs differ. Passes.
|
|
* misc.c (pthread_once): Use the POSIX mutex primitives, not Win32.
Remove irrelevant FIXME comment.
* pthread.h (PTHREAD_ONCE_INIT): Define.
* tests/once1.c: New file; test for pthread_once(). Passes.
|
|
* misc.c (pthread_equal): Correct inverted logic bug.
* tests/create1.c: New file; test pthread_create(). Passes.
* tests/equal.c: Poor test; remove.
* tests/equal1.c New file; test pthread_equal(). Passes.
|
|
* global.c (PTHREAD_MUTEX_INITIALIZER): Move to pthread.h.
* pthread.h (PTHREAD_MUTEX_INITIALIZER): Define.
(pthread_mutex_t): Reimplement as a struct containing a valid
flag. If the flag is ever down upon entry to a mutex operation,
we call pthread_mutex_create() to initialise the object. This
fixes the problem of how to handle statically initialised objects
that can't call InitializeCriticalSection() due to their context.
* mutex.c (pthread_mutex_init): Set valid flag.
(pthread_mutex_destroy): Clear valid flag.
(pthread_mutex_lock): Check and handle the valid flag.
(pthread_mutex_unlock): Likewise.
(pthread_mutex_trylock): Likewise.
* tests/mutex3.c: New file; test for the static initialisation
macro. Passes.
|
|
* 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).
|
|
* configure.in: Test for __stdcall, not _stdcall. Typo.
* configure: Regenerate.
|
|
* attr.c (pthread_attr_setstackaddr): Remove FIXME comment. Win32
does know about ENOSYS after all.
(pthread_attr_setstackaddr): Likewise.
|
|
* create.c (_pthread_start_call): Add STDCALL prefix.
|
|
* config.h.in: Regenerate.
|
|
* configure.in: Test for the `_stdcall' keyword. Define `STDCALL'
to `_stdcall' if we have it, null otherwise.
* configure: Regenerate.
* acconfig.h (STDCALL): New define.
|
|
* mutex.c (pthread_mutex_init): Correct function signature.
|
|
* attr.c (pthread_attr_init): Only zero out the `sigmask' member
if we have the sigset_t type.
* pthread.h (pthread_sigmask): Only provide if we have the
sigset_t type.
|
|
* pthread.h: No need to include <unistd.h>. It doesn't even exist
on Win32! Again, an artifact of cross-compilation.
|
|
* process.h: Remove. This was a stand-in before we started doing
native compilation under Win32.
* pthread.h (pthread_mutex_init): Make `attr' argument const.
|
|

|
|
|
|
|
|
* configure.in: Test for required system features.

* config.h.in: Generate.

|
|
POSIX TSD on top of Win32 TLS.
|
|
* windows.h: No longer needed; remove.
* windows.c: Likewise.
|
|
|
|
* {most}.c: Include <errno.h> to get POSIX error values.
* signal.c (pthread_sigmask): Only provide if HAVE_SIGSET_T is
defined.
* config.h: #undef features, don't #define them. This will be
generated by autoconf very soon.
|
|
* Makefile (LIB): Define.
(clean): Define target.
(all): Build a library not just the object files.
* pthread.h: Provide a definition for struct timespec if we don't
already have one.
* windows.c (TlsGetValue): Bug fix.
