* gthread/gthread-impl.c (g_thread_init_with_errorcheck_mutexes): Call
g_thread_impl_init(), as g_thread_init won't call it.
* glib/glib-sections.txt, glib/tmpl/threads.sgml: Added
g_static_mutex_free
* gthread.c, gthread.h: Added g_static_mutex_free to allow using
GStaticMutexes with limited lifetime without leaking.
* configure.in: GStaticMutex doesn't have to provide extra space
for debugging information for G_ERRORCHECK_MUTEXES, as then the
non-default implementation (runtime_mutex) is used anyway.
2001-01-30 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread.h (g_cond_wait): Added debug information for
g_mutex_free calls, if G_ERRORCHECK_MUTEXES is defined.
* gthread/gthread-impl.c (g_mutex_free_errorcheck_impl): Fixed it for
real. Sorry for this mess. It looked like a real obvious fix, so I
didn't check. Bad boy. Added some casts to quiet the compiler.
2001-01-29 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread.c: Broadcast the condition, if there are waiting
readers, as all might read at the same time. Only signal the
writer thread, if there are no more readers.
* gthread/gthread-impl.c (g_mutex_free_errorcheck_impl): Add
new check to errorcheck mutexes to abort, if a locked mutex is freed.
2000-11-28 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* 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.
2000-09-29 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in, glib.h: Added errorcheck mutexes. These are
activated through the preprocessor symbol
G_ERRORCHECK_MUTEXES. Need to add an extra word to StaticMutex in
order to achieve this. g_(static_)mutex_* functions instrument the
mutex operations with mutex name and location, when compiled with
-DG_ERRORCHECK_MUTEXES. g_thread_init activates the errorcheck
mutexes, when compiled with -DG_ERRORCHECK_MUTEXES.
* gthread/gthread-impl.c: Added errorcheck mutexes. New
exported function
g_thread_init_with_errorcheck_mutexes, which is called instead of
g_thread_init, when compiled with -DG_ERRORCHECK_MUTEXES. New
static functions
g_mutex_(new|lock|trylock|unlock|free)_errorcheck_impl to
implement errorcheck mutexes.
* gthread/gthread-posix.impl.c, gthread/gthread-solaris-impl.c:
Define the size of a mutex.

* *.[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.
2000-02-22 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread-posix.c, gthread-solaris.c: check for sysconf
(_SC_THREAD_STACK_MIN), which returns the minimal stack size for
new threads. Patch from Soeren Sandmann <sandmann@daimi.au.dk>.
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.
