* gthread-impl.c: Revamped errorcheck mutexes and added errorcheck
cond_wait() and cond_timed_wait() funtions. This makes he whole
thing work. Now we only show the location of the locking/unlocking
for -DG_ERRORCHECK_MUTEXES and not the name of the mutex.
* gthread.c: Set the thread data before locking the mutex, because
the locking call might use g_thread_self ().
* gthread.h: Do only show the location of the locking/unlocking
for -DG_ERRORCHECK_MUTEXES and not the name of the mutex. Add the
errorcheck capability for g_cond_wait and g_cond_timed_wait as
well.
2000-11-21 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Add a surrogate for thread priorities using PID
niceness for systems with no thread priorities and different PIDs
for threads of the same process (most notably: Linux). Define
G_THREAD_USE_PID_SURROGATE in that case, as used by
gthread-posix.c. Also make the system thread bigger by
sizeof (long) to contain the thread's PID.
* gfileutils.c: Include stdlib.h for mkstemp prototype.
* gthread.c: Add priority range checks to the affected functions.
* gthreadpool.c: Remove unused variable.
* gthread-impl.c, gthread-posix.c, gthread-solaris.c: Removed
g_thread_map_priority function in favour of the
g_thread_priority_map array. Initialize the array with
PRIORITY_{...}_VALUE, if available and interpolate beetween the
bounds if .._NORMAL_.. and .._HIGH_.. are not available.
* gthread-posix.c: If we should use the PID niceness as a
surrogate for thread priorities (G_THREAD_USE_PID_SURROGATE is
defined), then disable normal priority handling and use PIDs and
setpriority() instead. Depends on the thread to write its PID into
the place after the thread id right after thread creation.
2000-11-13 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread.c (g_static_rec_mutex_*): Made recursive mutexes also
work when the thread system is not (yet) initialized.
2000-09-01 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h: Include gerror.h before it is used for some g_thread_*
functions.
* gthread.c, gthreadpool.c, glib.h: Enable error reporting for
thread creation, namly for g_thread_create, g_thread_pool_new,
g_thread_pool_push and g_thread_pool_set_max_threads.
* tests/thread-test.c, tests/threadpool-test.c: Adapted
accordingly.
* gthread-posix.c (g_thread_create_posix_impl): Use GError to
report errors.

* *.[hc]: applied patch from Andreas Persenius <ndap@swipnet.se> that
updates the license headers to the GNU Lesser General Public License,
as well as updating the copyright year to 2000.
2000-03-17 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Added the missing POSIX_NO_YIELD and
POSIX_NO_PRIORITIES warning messages.
* configure.in: Use AC_TRY_RUN instead of AC_TRY_LINK, to test for
real thread support. On solaris pthread_create can be linked to
even in -lc, but it doesn't work then.
* configure.in: Don't use priorities for threads, when the
minimal/maximal priorities couldn't be determined at configure
time.
* configure.in, gthread.c: Always define GSystemThread in
glibconfig.h to represent a system thread.
* configure.in: Do not use native recursive threads, when
possibe. We use some features, that they do not expose (namely the
depth counter).
* glib.h, gthread.c: Redefined GStaticRecMutex. The functions are
now implemented in a different way, which should be way
faster. Alsothere are now functions g_static_rec_mutex_unlock_full
and g_static_rec_mutex_lock_full to leave/enter a recursive mutex
completly.
* gthread.c (g_thread_self): Do not test the system_thread to be
non-zero to speed things up.
* gthread.c (g_mutex_init): Therefore set the system_thread of the
main thread here.
* tests/thread-test.c: Rerun all tests once again, but this time
we fool the system into thinking, that the available thread system
is not native, but userprovided.
* gthread/gthread-posix.c: Don't use priorities for threads,
when the minimal/maximal priorities couldn't be determined at
configure time.
* gthread/gthread-posix.c: Don't check for errors, when
setting the scope of a tread to system, as some posix
implementations can't do that and we don't want the thing to
fail because of that.
1999-11-16 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* acconfig.h, config.h.win32.in, configure.in: Renamed
GLIB_SIZEOF_PTHREAD_T to GLIB_SIZEOF_SYSTEM_THREAD to reflect
changed meaning.
* configure.in: Cope with systems, that have a pthread_t type,
that is not a pointer. Hint from Karl Nelson
<kenelson@ece.ucdavis.edu>. Define GLIB_SIZEOF_SYSTEM_THREAD to 4
for Solaris. Cope with systems, that have no default mutex
initialize, like obviously most DCE systems.
* glib.h, gthread.c: Changed the prototype of thread_create and
thread_self to return the system thread into provided memory
instead of a return value. This is necessary, as HPUX has a
pthread_t, that is bigger than the biggest integral type there.
* gthread.c: system_thread is no longer a pointer, but an memory
area of size GLIB_SIZEOF_SYSTEM_THREAD. Changed the
zeroinitialization and the tests for zeroness accordingly.
* README.win32: Update the pthreads snapshot version we want.
Advice how to hand-expand the makefile.*.in files.
* config.h.win32.in: Define values needed by Sebastian Wilhelmi's
new thread stuff.
* glib.def: Add new functions.
* glibconfig.h.win32.in: Update the pthreads snapshot version.
Fix typo.
* gthread.c: Include config.h, guard inclusion of unistd.h. When
using gcc on Win32, g_thread_functions_for_glib_use must be marked
for export here, too.
* gtimer.c: Implement g_usleep on native Win32 using Sleep (which
only has millisecond granularity, though).
* makefile.cygwin.in
* makefile.msc.in: Update pthreads snapshot version. File
name changes. Remove testgthread.
* tests/makefile.cygwin.in
* tests/makefile.msc.in: Add thread-test. Link with gthread lib.
* gthread-posix.c: Guard pthread_attr_setscope call with test
for _POSIX_THREAD_PRIORITY_SCHEDULING, which should be defined
in a <pthread.h> that supports that feature.
1999-06-17 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in, acglib.m4, acconfig.h, glib.h, gthread.c:
Completed the thread support in GLib. Thread creation,
prioritizing threads, yielding, joining threads as well as
reader/writer locks and recursive mutexes are now in place. Please
test heavily on your platform. It is so far tested on
Linux/i386/pthreads, Solaris/Sparc/pthreads and
Solaris/Sparc/solaristhreads.
* gtimer.c, glib.h: Implement g_usleep (gulong microseconds) for
thread safe sleeping. (sleep() is not MT-safe at all!)
* gutils.c: Avoid compiler warning.
* tests/Makefile.am, tests/thread-test.c: New program to test some
aspects of the thread implementation.
* gthread.c, Makefile.am: Renamed from gmutex.c to reflect the
change of content.
* configure.in: Purged all appearances of nspr.
* gthread/gthread-posix.c, gthread-solaris.c: Added the native
implementations for the GLib's extended thread support.
* gthread/gthread-nspr.c: Removed for good. NSPR is nothing we
would want to build upon.
* gthread/gthread.c: Renamed to gthread-impl.c to avoid
confusion with ../gthread.c (Formerly known as the file called
gmutex.c)
* gthread/testgthread.c: Removed. The new and much extended
tests are in ../tests/thread-test.c.
* gthread/Makefile.am: Changed to reflect the changes above.
