2001-02-15 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* acconfig.h, configure.in: Reverted the changes necessary to
enlarge the system thread for G_THREAD_USE_PID_SURROGATE.
* gthread.c: Now implement G_THREAD_USE_PID_SURROGATE in gthread.c
instead of gthread/gthread-posix.c. While the latter has the
advantage, that it is conceptually cleaner, it makes
g_thread_self_posix_impl _very_ slow and that hurts
GStaticRecMutex and other things. So the new version is less
clean, but faster.
* gthread-posix.c: Removed the G_THREAD_USE_PID_SURROGATE
implementation, which is now in gthread.c.
2001-01-03 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* 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.
2000-11-15 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Check for the sched.h header and include it on
gthread/gthread-posix.c if available.
* gthread-posix.c: Include <sched.h> if available.
* configure.in: Add -D_POSIX4_DRAFT_SOURCE to
GTHREAD_COMPILE_IMPL_DEFINES. Also add -D_POSIX4A_DRAFT10_SOURCE
to G_THREAD_CFLAGS. Really deploy GTHREAD_COMPILE_IMPL_DEFINES,
when searching for thread libs. Look for sched_* functions in
-lrte as well. All of that is necessary on DG/UX.
* configure.in: Use AC_TRY_COMPILE instead of AC_EGREP_HEADERS in
various places to make it work more reliable, to make it accept
macros instead of functions etc.
* configure.in: Replace some NULL's for checks with 0 to make it
work without stdio.h everywhere.
* configure.in, gutils.c: changed the test for getpwuid_r to first
test for a posix version and then for a non-posix version. No code
change in gutils.c. Again this change deals better with getpwuid_r
being a macro and not a function. Most of the above with kind help
from Tethys <tet@isengard.europe.dg.com>. This fixes Bug #13403.
2000-10-25 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* Makefile.am : Add @GLIB_DEBUG_FLAGS@ to INCLUDES for accessing
-DG_ENABLE_DEBUG as needed in gthread-posix.c.
* gthread-posix.c: Revamped error handling for native thread
function calls. Now EPERM errors are ignored for some commands and
only a warning message is output once (at first occurrence).
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/
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.
Wed Jul 26 12:59:31 2000 Tim Janik <timj@gtk.org>
* *.[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.
2000-03-20 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread-posix.c (posix_check_for_error): Forgot a '}' in a macro
for DCE-threads. Thanks to Karl Nelson <kenelson@ece.ucdavis.edu>
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.
* 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.
1999-03-31 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread/gthread-posix.c: Use the right default arguments for the
construction of mutexes and conds for dce threads, these are
&pthread_(cond|mutex)attr_default instead of NULL. Hint from
D. Emilio Grimaldo Tunon <emilio_tunon@nl.compuware.com>.
1999-03-12 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Test for posix threads first, then for dce threads.
* gthread/gthread-posix.c (g_private_get_posix_impl): Fixed
typo for DCE implementation.
1999-03-11 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Revamped the thread configure stuff. Now dce
threads (old posix draft) are recogniced. This is necessary,
because dce threads are in fact working quite differently from
posix threads. Also changed the conditions for checking for MT
safe functions a bit, because G_THREADS_IMPL_NONE still have to
compile thread safe.
* gthread/gthread-posix.c: Now handle both dce and posix
threads. They are sufficently equal.
NOTE: Please do not commit my change to
glib-1-2/{acconfig.h,configure.in,config.h.win32} from 1999-03-03, as
the current change will take care of that too.
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.
1999-02-08 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in, acconfig.h: Changed the test for getpwuid_r to
exclude those systems (i.e. IRIX), that set ENOSYS after the call.
Test, if pthread_getspecific is posix like or something different,
as on PCThreads.
* gthread/gthread-posix.c (g_private_get_posix_impl): Use the
HAVE_PTHREAD_GETSPECIFIC_POSIX macro to determine, which signature
to use for pthread_getspecific.
* README.win32: More text.
* config.h.win32 glibconfig.h.win32: Update to match the
corresponding generated files on Unix.
* makefile.msc: Update with new source files, and gthread
library. Use the compiler flag -MD instead of using -D_DLL and
"/nodefaultlib:libc msvcrt.lib" in the link phase.
* glib.def: Include new functions, drop removed ones.
* glib.h: Add comments about main loop and polling on Win32. (In
general, it's only for the GIMP's use.) Add Win32 IO Channel
functions. Remove the obsoleted old IO Channel stuff (which was
in #if 0 already).
* giowin32.c: New file.
* gmain.c: Include config.h, conditionalize <sys/time.h>
inclusion. Add g_poll implementation for Win32 (only for the
GIMP's needs for now, it's hard or even impossible to be as clean
and generic as on Unix). Implement g_get_current_time on Win32. If
threads aren't supported, don't try to wake up main thread's
loop. On Win32, use a semaphore and not a pipe to wake up the main
loop.
* gmessages.c: On Win32, allocate a console window if the standard
output handle is invalid before writing to stdout, and reopen stdout
to that console window.
* giochannel.c: Conditionalize unistd.h inclusion. Some indentation
cleanup.
* gstrfuncs.c: Include <signal.h>.
* gutils.c: On Win32, also check the HOMEDRIVE and HOMEPATH
environment variables.
* gmodule-dl.c gmodule-dld.c: In
_g_module_build_path, don't add the "lib" prefix and
".so" or ".sl" suffix if already there.
* gmodule-win32.c: Likewise for the ".dll" suffix.
* gthread-posix.c: Conditionalize <sys/time.h> inclusion.

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.
