G_THREADS_ENABLED still exists, but is always defined. It is still
possible to use libglib without threads, but gobject (and everything
above it) is now guaranteed to be using threads (as, in fact, it was
before, since it was accidentally impossible to compile with
--disable-threads).

2003-07-09 Matthias Clasen <maclas@gmx.de>
Support for one-time initialization functions. (#69668, Sebastian Wilhelmi)
* configure.in: Check whether double checked locking is safe, define g_once() in
glibconfig.h accordingly.
* glib/gthread.h: Add GOnce, GOnceStatus, G_ONCE_INIT and g_once_impl.
* glib/gthread.c (g_once_impl): Fallback implementation using a mutex if double checked
locking is unsafe.
* tests/thread-test.c: Add tests for g_once().
2002-07-04 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* tests/*.c: Added #undef G_DISABLE_ASSERT and #undef G_LOG_DOMAIN
throughout the files, which didn't already have them. (#87312)
2002-02-15 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* tests/thread-test.c: Do not assume, that after
g_usleep(G_USEC_PER_SEC) the newly started thread began
running. Spotted by Miroslaw Dobrzanski-Neumann
<mne@mosaic-ag.com>. Make the test_g_static_rw_lock_thread threads
wait a random time. Make the test_g_static_rw_lock test run 5
seconds, not 1.
2001-05-18 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread.c, gthread.h: Renamed g_thread_create to
g_thread_create_full and added macro g_thread_create, which omits
'stack_size', 'bound' and 'priority' parameters. Also removed
'bound' from GThread struct.
* gthreadpool.h, gthreadpool.c: Adapted GThreadPool to the above
changes. GThreadPool lost the 'priority' and 'bound'
members. g_thread_pool_new the 'stack_size', 'bound' and
'priority' parameters.
* tests/mainloop-test.c, tests/thread-test.c,
tests/threadpool-test.c: Adapted to the above changes.
2001-05-08 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gmain.c, gthread.c, gthread.h: Moved func and arg members from
GRealThread to GThread, such that they can be accessed by the
user.
* gthread.c, gthread.h: Due to popular demand (Tim being the
populus here ;-) threads now have a 'return value', which is
returned by g_thread_join and is either the return of the topmost
thread function or the value given to g_thread_exit.
* gthreadpool.c, tests/mainloop-test.c, tests/thread-test.c:
Adapted to the above change.
2001-02-13 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread.c, gthread.h: Added functions g_static_rec_mutex_init,
g_static_rec_mutex_free, g_static_private_init,
g_static_private_free, g_static_rw_lock_init to allow the usage of
all those types dynamically. (g_static_rw_lock_free already
existed). Aditionally freed static_private indeces are reused
now. Untill now the array would just grow if you would use more
and more static_private. That required adding a slist of all
running threads, which could potentially be of good use later. It
is not exported however. Renamed a LOCK and small indentation
fixes.
* tests/thread-test.c: Test the new static_private index freing
and reusing feature.
2000-09-06 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h, gtimer.c, tests/thread-test.c:
s/G_MICROSEC/G_USEC_PER_SEC/
* gthread/gthread-posix.c, gthread/gthread-solaris.c:
s/G_MICROSEC/G_USEC_PER_SEC/ and s/G_NANOSEC/G_NSEC_PER_SEC/
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.
2000-04-19 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h (G_TRYLOCK): Made the debugging G_TRYLOCK call also work
for compilers with funnt G_STMT_(START|END) macros.
* tests/thread-test.c: Implemented a check for that.
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.
1999-06-17 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.
