1999-10-23 Ross Johnson <rpj@ixobrychus.canberra.edu.au>

tests/ChangeLog:
1999-10-30 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
* cancel1.c: New. Test pthread_setcancelstate and
pthread_setcanceltype functions.
* eyal1.c (waste_time): Change calculation to avoid FP exception
on Aplhas
- Rich Peters <rpeters@micro-magic.com>

|
* rwlock.c (pthread_rwlock_destroy): Add cast to remove compile
warning.
* condvar.c (pthread_cond_broadcast): Only release semaphores
if there are waiting threads.
1999-10-15 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
* condvar.c (cond_wait_cleanup): New static cleanup handler for
cond_timedwait;
(cond_timedwait): pthread_cleanup_push args changed;
canceling a thread while it's in pthread_cond_wait
will now decrement the waiters count and cleanup if it's the
last waiter.
- Lorin Hochstein <lmh@xiphos.ca> and
Peter Slacik <Peter.Slacik@tatramed.sk>;
the last waiter will now reset the CV's wasBroadcast flag
- Graham Dumpleton <Graham.Dumpleton@ra.pad.otc.telstra.com.au>.

* private.c (_pthread_threadStart): Return exit status from

* sync.c (pthread_join): use pthread_exitStatus value if the
thread exit doesn't return a value (for Mingw32 CRTDLL
which uses endthread instead of _endthreadex).

./tests/ChangeLog
Sat May 29 23:29:04 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
* runall.bat (condvar5): Add new test.
* runall.bat (condvar6): Add new test.
* Makefile (condvar5) : Add new test.
* Makefile (condvar6) : Add new test.
* condvar5.c: New test for pthread_cond_broadcast().
* condvar6.c: New test for pthread_cond_broadcast().

* errno.c (_REENTRANT || _MT): Invert #if condition.
* pthread.h (_errno): Conditionally include prototype.
|
|
* *.c (comments): Remove individual attributions - these are
documented sufficiently elsewhere.
* implement.h (pthread.h): Remove extraneous include.
|
|
* 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.

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.

* misc.c (CancelableWait): Ensure cancelEvent handle is the lowest
indexed element in the handles array. Enhance test for abandoned
objects.
* pthread.h (PTHREAD_MUTEX_INITIALIZER): Trailing elements not
initialised are set to zero by the compiler. This avoids the
problem of initialising the opaque critical section element in it.
(PTHREAD_COND_INITIALIZER): Ditto.
* semaphore.c (_pthread_sem_timedwait): Check sem == NULL earlier.
Sun Mar 7 12:31:14 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
* condvar.c (pthread_cond_init): set semaphore initial value
to 0, not 1. cond_timedwait was returning signaled immediately.
* misc.c (CancelableWait): Place the cancel event handle first
in the handle table for WaitForMultipleObjects. This ensures that
the cancel event is recognised and acted apon if both objects
happen to be signaled together.
* private.c (_pthread_cond_test_init_lock): Initialise and destroy.
* implement.h (_pthread_cond_test_init_lock): Add extern.
* global.c (_pthread_cond_test_init_lock): Add declaration.
* condvar.c (pthread_cond_destroy): check for valid initialised CV;
flag destroyed CVs as invalid.
(pthread_cond_init): pthread_cond_t is no longer just a pointer.
This is because PTHREAD_COND_INITIALIZER needs state info to reside
in pthread_cond_t so that it can initialise on first use. Will work on
making pthread_cond_t (and other objects like it) opaque again, if
possible, later.
(cond_timedwait): add check for statically initialisation of
CV; initialise on first use.
(pthread_cond_signal): check for valid CV.
(pthread_cond_broadcast): check for valid CV.
(_cond_check_need_init): Add.
* pthread.h (PTHREAD_COND_INITIALIZER): Fix.
(pthread_cond_t): no longer a pointer to pthread_cond_t_.
(pthread_cond_t_): add 'staticinit' and 'valid' elements.

Sun Mar 7 10:41:52 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
* Makefile (condvar3, condvar4): Add tests.
* condvar4.c (General): Reduce to simple test case; prerequisite
is condvar3.c; add description.
* condvar3.c (General): Reduce to simple test case; prerequisite
is condvar2.c; add description.
* condvar2.c (General): Reduce to simple test case; prerequisite
is condvar1.c; add description.
* condvar1.c (General): Reduce to simple test case; add
description.
* Template.c (Comments): Add generic test detail.
|
|
* Makefile (condvar3, condvar4): Add tests.
|
|
* Template.c: Revamp.
* condvar1.c: Add.
* condvar2.c: Add.
* Makefile: Add condvar1 condvar2 tests.
* exit1.c, exit2.c, exit3.c: Cosmetic changes.
|
|
* Makefile: Some refinement.
* *.c: More exhaustive checking through assertions; clean up;
add some more tests.
|
|
* Makefile: Now actually runs the tests.
* tests.h: Define our own assert macro. The Mingw32
version pops up a dialog but we want to run non-interactively.
* equal1.c: use assert a little more directly so that it
prints the actual call statement.
* exit1.c: Modify to return 0 on success, 1 on failure.
|
|
* 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.
