* pthread.h (pthread_mutexattr_t): Changed to a pointer.
* mutex.c (pthread_mutex_init): Conditionally create Win32 mutex
- from John Bossom's implementation.
(pthread_mutex_destroy): Conditionally close Win32 mutex
- from John Bossom's implementation.
(pthread_mutexattr_init): Replaced by John Bossom's version.
(pthread_mutexattr_destroy): Ditto.
(pthread_mutexattr_getpshared): New function from John Bossom's
implementation.
(pthread_mutexattr_setpshared): New function from John Bossom's

* misc.c (CancelableWait): New static function is
pthreadCancelableWait() renamed.
(pthreadCancelableWait): Now just calls CancelableWait() with
INFINITE timeout.
(pthreadCancelableTimedWait): Just calls CancelableWait()
with passed in timeout.
* private.c (_pthread_sem_timedwait): 'abstime' arg really is
absolute time. Calculate relative time to wait from current
time before passing timeout to new routine
pthreadCancelableTimedWait().

Tue Jan 19 10:27:39 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
* pthread.h (pthread_mutexattr_setforcecs_np): New prototype.
* mutex.c (pthread_mutexattr_init): Init 'pshared' and 'forcecs'
attributes to 0.
(pthread_mutexattr_setforcecs_np): New function (not portable).
* pthread.h (pthread_mutex_t):
Add 'mutex' element. Set to NULL in PTHREAD_MUTEX_INITIALIZER.
The pthread_mutex_*() routines will try to optimise performance
by choosing either mutexes or critical sections as the basis
for pthread mutexes for each indevidual mutex.
(pthread_mutexattr_t_): Add 'forcecs' element.
Some applications may choose to force use of critical sections
if they know that:-
the mutex is PROCESS_PRIVATE and,
either the OS supports TryEnterCriticalSection() or
pthread_mutex_trylock() will never be called on the mutex.
This attribute will be setable via a non-portable routine.
Note: We don't yet support PROCESS_SHARED mutexes, so the
implementation as it stands will default to Win32 mutexes only if
the OS doesn't support TryEnterCriticalSection. On Win9x, and early
versions of NT 'forcecs' will need to be set in order to get
critical section based mutexes.
Sun Jan 17 12:01:26 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
* pthread.h (PTHREAD_MUTEX_INITIALIZER): Init new 'staticinit'
value to '1' and existing 'valid' value to '1'.
* global.c (_pthread_mutex_test_init_lock): Add.
* implement.h (_pthread_mutex_test_init_lock.): Add extern.
* private.c (_pthread_processInitialize): Init critical section for
global lock used by _mutex_check_need_init().
(_pthread_processTerminate): Ditto (:s/Init/Destroy/).
* dll.c (dllMain): Move call to FreeLibrary() so that it is only
called once when the process detaches.
* mutex.c (_mutex_check_need_init): New static function to test
and init PTHREAD_MUTEX_INITIALIZER mutexes. Provides serialised
access to the internal state of the uninitialised static mutex.
Called from pthread_mutex_trylock() and pthread_mutex_lock() which
do a quick unguarded test to check if _mutex_check_need_init()
needs to be called. This is safe as the test is conservative
and is repeated inside the guarded section of
_mutex_check_need_init(). Thus in all calls except the first
calls to lock static mutexes, the additional overhead to lock any
mutex is a single memory fetch and test for zero.
* pthread.h (pthread_mutex_t_): Add 'staticinit' member. Mutexes
initialised by PTHREAD_MUTEX_INITIALIZER aren't really initialised
until the first attempt to lock it. Using the 'valid'
flag (which flags the mutex as destroyed or not) to record this
information would be messy. It is possible for a statically
initialised mutex such as this to be destroyed before ever being
used.
* mutex.c (pthread_mutex_trylock): Call _mutex_check_need_init()
to test/init PTHREAD_MUTEX_INITIALIZER mutexes.
(pthread_mutex_lock): Ditto.
(pthread_mutex_unlock): Add check to ensure we don't try to unlock
an unitialised static mutex.
(pthread_mutex_destroy): Add check to ensure we don't try to delete
a critical section that we never created. Allows us to destroy
a static mutex that has never been locked (and hence initialised).
(pthread_mutex_init): Set 'staticinit' flag to 0 for the new mutex.

* pthread.h: Add new 'abstime' arg to pthreadCancelableWait()
prototype.
* condvar.c (cond_timedwait): New generalised function called by
both pthread_cond_wait() and pthread_cond_timedwait(). This is
essentially pthread_cond_wait() renamed and modified to add the
'abstime' arg and call the new _pthread_sem_timedwait() instead of
sem_wait().
(pthread_cond_wait): Now just calls the internal static
function cond_timedwait() with an INFINITE wait.
(pthread_cond_timedwait): Now implemented. Calls the internal
static function cond_timedwait().
* implement.h (_pthread_sem_timedwait): New internal function
prototype.
* misc.c (pthreadCancelableWait): Added new 'abstime' argument
to allow shorter than INFINITE wait.
* semaphore.c (_pthread_sem_timedwait): New function for internal
use. This is essentially sem_wait() modified to add the
'abstime' arg and call the modified (see above)
pthreadCancelableWait().

Thu Jan 14 14:27:13 1999 Ross Johnson <rpj@swan.canberra.edu.au>
* cleanup.c: Correct _cplusplus to __cplusplus wherever used.
* Makefile.in: Add CC=g++ and add -fhandle-exceptions to CFLAGS.
The derived Makefile will compile all units of the package as C++
so that those which include try/catch exception handling should work
properly. The package should compile ok if CC=gcc, however, exception
handling will not be included and thus thread cancellation, for
example, will not work.
* cleanup.c (_pthread_pop_cleanup): Add #warning to compile this
file as C++ if using a cygwin32 environment. Perhaps the whole package
should be compiled using g++ under cygwin.
* private.c (_pthread_threadStart): Change #error directive
into #warning and bracket for __CYGWIN__ and derivative compilers.

* pthread.h: Define ETIMEDOUT. This should be returned by
pthread_cond_timedwait which is not implemented yet as of
snapshot-1999-01-04-1305. It was implemented in the older version.
The Microsoft compiler pragmas probably are more appropriately

* pthread.def: pthread_mutex_destroy was missing from the def file
- Tor Lillqvist <tml@iki.fi>.
* condvar.c (pthread_cond_broadcast): Ensure we only wait on threads
if there were any waiting on the condition.
I think pthread_cond_broadcast should do the WaitForSingleObject
only if cv->waiters > 0? Otherwise it seems to hang, at least in the
testg thread program from glib.
- Tor Lillqvist <tml@iki.fi>.
* semaphore.c (sem_post): Correct typo in comment.

Parts of this package are going to have to be C++ in the GNU world because we
now use exception handling to implement thread cancellation. The MSC compiler
appears to know about __try/__except blocks, but gcc (ie. the GNU ANSI C
compiler) doesn't know about the equivalent C++ try/catch blocks. This should
not be a problem since gcc and g++ are nearly always available together. Some
file names may need to change in the CVS repository however.
Tue Jan 5 16:33:04 1999 Ross Johnson <rpj@swan.canberra.edu.au>
* cleanup.c (_pthread_pop_cleanup): Add C++ version of __try/__except
block. Move trailing "}" out of #ifdef _WIN32 block left there by
(my) mistake.
* private.c: Remove #include <errno.h> which is included by pthread.h.
