* gthread-solaris.c, gthread-posix.c: Made g_thread_min_stack_size
static.
2CVS: ----------------------------------------------------------------------
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.
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/

* *.[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.
2000-04-25 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread-solaris.c (g_mutex_new_solaris_impl): Changed the scope
of the initialized mutex to USYNC_THREAD. Thanks to Soeren
Sandmann <sandmann@daimi.au.dk> for pointing that out.
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.
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>.
1999-11-16 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread-posix.c, gthread-solaris.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. Made some more functions static.
* gthread-posix.c: Small fixes for DCE threads: Detaching has to
be done after thread creation for DCE.
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.
Wed Feb 24 00:08:42 CST 1999 Shawn T. Amundson <amundson@gtk.org>
* *.[ch]: inserted additional note to look for ChangeLog and
AUTHORS file for a log of modifications.
1998-12-15 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* Makefile.am (EXTRA_DIST): updated.
* testgthread.c, gthread-*.c: Changed private to private_key to
avoid problems when compiling with under C++.
branch. See the ChangeLog for details of the changes.
In brief overview:
- The set of threading functions can be set
- A default implementation is provided in -lgthread
- All static data structures are locked using these
functions if g_thread_init() is called.
