instead of a pthread_mutex_t.

* cancel.c (pthread_cancel): Must get "self" through
calling pthread_self() which will ensure a POSIX thread
struct is built for non-POSIX threads; return an error
if this fails
- Ollie Leahy <ollie@mpt.ie>
(pthread_setcancelstate): Likewise.
(pthread_setcanceltype): Likewise.
* misc.c (ptw32_cancelable_wait): Likewise.
* private.c (ptw32_tkAssocCreate): Remove unused #if 0
wrapped code.
* pthread.h (ptw32_get_exception_services_code):
Needed to be forward declared unconditionally.
2000-09-06 Ross Johnson <rpj@special.ise.canberra.edu.au>
* cancel.c (pthread_cancel): If called from the main
thread "self" would be NULL; get "self" via pthread_self()
instead of directly from TLS so that an implicit
pthread object is created.
* misc.c (pthread_equal): Strengthen test for NULLs.

* 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.
|
|
* All applicable: Change _pthread_ prefix to
ptw32_ prefix to remove leading underscores
from private library identifiers (single
and double leading underscores are reserved in the
ANSI C standard for compiler implementations).
|
|
* 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.

It was ok under NT.
