* configure.in: After finding the right thread library (containing
e.g. pthread_create) we now search for the right realtime library
(containing e.g. sched_get_priority_max). Makes the output of the
thread related libraries correct.
* gtimer.c (g_usleep): The current implementation of g_usleep
(simply calling select) doesn't work reliable for multi-threaded
programs on some platforms (bad omen for the main loop....), so I
changed the implementation for thread-using programs to wait for a
GCond for the specified amount of time (NB: sleep and usleep are
not MT-safe in general, because they often use signals).
2000-03-23 Tor Lillqvist <tml@iki.fi>
* gmodule-win32.c (_g_module_symbol): When looking for symbols in
the "main" module we must search both the main program and all
currently loaded DLLs. Not only the main program, or even just the
DLLs loaded as gmodules. Libglade requires this.
Thus we need to get a list of all modules in the current
process. There are two alternative APIs to do this: PSAPI and
Toolhelp. The former is only available on NT (including Win2k),
the latter on Win9x and Win2k. Check which one works, and use
that.
Code for using PSAPI and Toolhelp was borrowed from the Dr. Mingw
tool written by José Fonseca <em96115@fe.up.pt>. Thanks.
2000-03-22 Tor Lillqvist <tml@iki.fi>
* gutils.c: Move Win32-only includes after inclusion of glib.h, so
that G_OS_WIN32 is defined.
* glibconfig.h.win32.in: Add GSystemThread.
2000-03-22 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gutils.c (g_get_current_dir): Ok, Marcus Brinkmann
<Marcus.Brinkmann@ruhr-uni-bochum.de> convinced me, that 128 KB
path length might not be enough for the HURD. So I changed the
loop to at least avoid an integer overflow, which could happen at
beyond 2GB size ;-)
2000-03-22 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Test for sched_yield as the native yield function
first. Corrected typo g_thread_sleep -> g_usleep. Corrected
message for the pthread_create test. Negative Priorities are
allowed (and used on Solaris), so consider
sched_get_priority_min failed only if it returns -1, not <0. Check
for sched_get_priority_min also in -lrt, if not found in -lpthread
alone and add -lrt to G_THREAD_LIBS then. Remove special case
handling of priorities for older solaris versions and posix
threads. Thanks to Wan-Teh Chang <wtc@netscape.com> for suggesting
some of those changes.
* config.guess, config.sub, ltconfig, ltmain.sh:
Upgrade to libtool 1.3.4.
2000-03-21 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h, configure.in, gutils.h: always define G_GNUC_EXTENSION,
even when not needed by GLib. That's actually also the way, the
GLib reference manual describes that macro. Therefore I had to
remove the lonesome #include <glibconfig.h> in gutils.c, which
doesn't seem to be needed there however. This change should make
Ben Gertzfield <che@debian.org> happy.
* gutils.c: Furthermore two warnings in gutils.c were voided,
which crept in due to my last change.
2000-03-21 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gutils.c (g_get_current_dir): Allocate only up to 128KB for a
pathname. While this is an arbitrary value just like 2048, it
seems to be enough (after all, even 4GB is an arbitrary value).
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.
2000-03-20 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gmain.c (g_main_poll): Warn in case of an error during the call
to poll(2). Closes Bug#7564 as reported by David Helder
<dhelder@umich.edu>.
2000-03-20 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gutils.c (g_get_current_dir): Make g_get_current_dir work on
systems with unlimited pathname length like the HURD (It worked
there before, but only for pathes shorter than 2048). Closes
Bug#4525 as reported by Marcus Brinkmann
<Marcus.Brinkmann@ruhr-uni-bochum.de>.
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.
2000-03-13 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gqueue.c (g_queue_push_tail_link, g_queue_push_head_link): We
want the next and prev pointer of the inserted link to be NULL.
2000-03-04 Tor Lillqvist <tml@iki.fi>
* gwin32.c (g_win32_error_message): New function that returns the
message string for a Win32 error code.
* glib.h: Declare it.
* glib.def: Export it, plus g_node_copy.
* gmodule-win32.c: Call g_win32_error_message() to get the error
message strings.
* libgplugin_a.c
* libgplugin_b.c
* gmodule.c: Remove LibMain functions that were needed by LCC,
which is not a supported compiler.
* testgmodule.c (main): Test for G_MODULE_IMPL ==
G_MODULE_IMPL_WIN32, not G_OS_WIN32.
* gmoduleconf.h.win32: Remove LCC stuff from here, too.
2000-03-03 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Make the search for pthread_attr_... prototypes
find names at the start of a line also, like it is on AIX. Thanks
to Valdis Kletnieks <Valdis.Kletnieks@vt.edu> for the info.
2000-03-04 Tor Lillqvist <tml@iki.fi>
* gwin32.c (g_win32_error_message): New function that returns the

* gmoduleconf.h.win32: Remove LCC stuff from here, too.
Wed Mar 1 10:39:39 2000 Tim Janik <timj@gtk.org>
* gslist.c (g_slist_reverse): minor optimization.
* testglib.c (g_node_test): added a couple of tests for
g_node_copy().
* glib.h:
* gnode.c (g_node_copy): new function to copy subtrees,
supplied by dbsears@ix.netcom.com.
changed iterator to walk the children list backwards, so
we get down from O(n^2) to O(n).
* gnode.c (g_node_first_sibling): applied patch from
dbsears@ix.netcom.com to optimize access if node->parent
is present.
* gutils.c (g_get_any_init): backed out HAVE_PW_GECOS check around
assignment of g_real_name, sicne HAVE_PW_GECOS is never defined and
thus breaks the original code.
* merged changes from 1.2.7.
Sat Feb 19 19:43:29 2000 Tim Janik <timj@gtk.org>
* testgmodule.c (main): added test to check that not yet bound symbols
in shared libraries of the main module are retrievable, from David Gero.
Fri Jan 28 11:37:41 2000 Owen Taylor <otaylor@redhat.com>
Bug #4156 - Changes vaguely modelled after Scott Gifford's patch
* gtimer.c (g_timer_elapsed): Never report negative times -
clip times to 0.
* gmain.c (g_timeout_prepare): Guard against unexpected
clock shifts by never setting a timeout of more than
data->interval msecs.
Wed Mar 1 05:34:47 2000 Tim Janik <timj@gtk.org>

* gmodule-beos.c: many coding style fixups.
(_g_module_open):
(_g_module_self):
(_g_module_close):
(_g_module_symbol): bunch of memory leaks plugged.
* gmodule-dl.c: make sure the error message returned from dlerror()
is always != NULL, by using a wrapper function fetch_dlerror(). based
on a patch to fix _g_module_symbol() for NetBSD from Scott Presnell
<srp@zgi.com>.
* gmodule-dld.c: minor indentation.
* gmodule-win32.c: minor cleanups.
* merges from glib-1-2.

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>.
2000-02-21 Damon Chaplin <damon@helixcode.com>
* tmpl/main.sgml: updated the g_source_remove_by_XXX() descriptions
to note that only the first source found is removed.
2000-02-18 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Changed GCC version test to also accept major
versions > 2. Thanks to Ben Gertzfield <che@debian.org> for
pointing this out.
Thu Feb 17 12:53:44 2000 Tim Janik <timj@gtk.org>
* gstring.c: changed g_str_hash() to a 31 bit version based on
a submission by Karl Nelson and hand optimized ad absurdum by
various people ;)
* gstring.c: applied patch from havoc for new gstring functions,
added some more sanity checks, coding style fixups.
2000-02-13 Havoc Pennington <hp@pobox.com>

Sun Feb 13 08:16:47 2000 Tim Janik <timj@gtk.org>
* configure.in: wtf??? someone destroyed the configure.in, reverting to
an older version from Feb 4 which apears to still work.
2000-02-05 Tor Lillqvist <tml@iki.fi>
* glib.rc.in gmodule.rc.in gthread.rc.in: New files, for putting
version info in the DLLs on Win32.
* Makefile.am: Generate corresponding *.rc files and distribute
them.
* makefile.cygwin.in: Add rules to automatically bump a "build
number" in the version info in the rc files each time the DLL is
built. But do this only for the person who releases binaries. If
others build the DLLs, the build number is set to zero.
Fri Feb 4 19:36:05 2000 Tim Janik <timj@gtk.org>
* glib.h:
* gdataset.c: return stolen data from g_datalist_id_remove_no_notify()
and g_dataset_id_remove_no_notify() to avoid second lookup for common
use.
2000-02-01 Tor Lillqvist <tml@iki.fi>
* glib.h
* gstrfuncs.c (g_filename_to_utf8, g_filename_from_utf8): New
functions for conversion between UTF-8 and the encoding expected
by C runtime functions like open() and stat(), and returned by
readdir().
Implement them on Win32 where we use the system "ANSI" codepage,
which might be single-byte or double-byte. On Unix, just skip the
issue for now and provide dummy implementations that return a copy
of the argument.
* README.win32
* build-dll
* glib.def: Minor updates.
2000-01-25 Damon Chaplin <damon@karuna.freeserve.co.uk>
* tmpl/misc_utils.sgml: g_bit_nth_lsf/msf docs from
Nils Rennebarth <nils@ipe.uni-stuttgart.de>, and updates for
GVoidFunc & GFreeFunc.
Wed Jan 26 05:24:38 2000 Tim Janik <timj@gtk.org>
* glib.h:
* gmain.c: s/current_time/dispatch_time/ for the dispatch() handlers.
refetch the current time after invocation of poll() to cover up for
the time spent in that function call.
Fri Jan 21 10:18:24 2000 Owen Taylor <otaylor@redhat.com>
* glib.h (G_N_ELEMENTS): Added G_N_ELEMENTS macro to determine
the number of elements in an array.
found; this leads to an incorrect return value of g_module_symbol.]
2000-01-13 Martin Baulig <martin@home-of-linux.org>
* gmodule.c (g_module_open): Check whether `check_init' is not NULL
before we attempt to call it.
1999-12-02 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib-sections.txt, tmpl/threads.sgml: Removed
G_THREADS_IMPL_NSPR. Shouldn't be used anyway.
* glib-overrides.txt: New file, that makes most of the thread
related macros look like functions.
* Makefile.am: Added glib-overrides.txt to EXTRA_DIST.
* tmpl/threads.sgml: Minor updates.
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.
