2000-04-28 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gasyncqueue.c: New File implementing an asynchronous queue to be
used for asynchronous inter-thread communication.
* gthreadpool.c: New File implementing a thread pool to be used
for distributing work among several threads.
* glib.h: Added the type and function declarations for these two
types.
* tests/threadpool-test.c: New File implementing a test for the
thread pool. This also checks the asynchronous queue underlying
the thread pool.
* tests/Makefile.am: Changed accordingly.
2000-04-26 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Look for both pthread_create and pthread_join in
the thread library. Some systems define one of them, but not both
in libc. Arghh. Now we really start a thread and join it later and
check, whether the thread to actually ran.
2000-04-26 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h, gcache.c, gtree.c: Changed the 'value' parameter of
g_cache_remove from gpointer to gconstpointer. Dito for the 'key'
parameter of g_tree_lookup and g_tree_remove and the 'data'
parameter of g_tree_serach. This function now takes a function of
type GCompareFunc instead of GSearchFunc.
* glib.h: Removed declaration of GSearchFunc.
* gmem.c: s/GSearchFunc/GCompareFunc/.
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.
2000-04-19 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.
2000-04-19 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gutils.c (g_getenv): Changed the win32 part of this function to
be thread safe and to make the returned environment string
persistent to match the UN*X behavior. This is again a response to
Bug #8983.
* glib.h (G_LOCK_NAME): Removed parentheses around the lock name,
as that seems to cause problems for some compilers and really
isn't necessary.
Wed Apr 19 08:32:32 2000 Tim Janik <timj@gtk.org>
* gscanner.c (g_scanner_new): make sure that
scanner->config->cset_skip_characters is "" instead of NULL, so we
don't segfault further on.
2000-04-18 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h, glist.h, gslist.h: Changed the 'data' parameters from
gpointer to gconstpointer for the functions
g_(list|slist)_(remove|find|find_custom|index), as they do not
change this parameter. This fixes bug #4836.
2000-04-18 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h: Changed comment for g_getenv to reflect, that the
returned memory must not be freed. Fixes Bug #8983.
2000-04-17 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in, acconfig.h: Add configure test for garbage
collector friendliness for GLib. If enabled, ENABLE_GC_FRIENDLY
will be defined.
* garray.c, ghash.c, glist.c, gmain.c, gmem.c, gnode.c, gqueue.c,
gslist.c, gtree.c: If ENABLE_GC_FRIENDLY is defined, NULLify all
memory released by the user, but cached by GLib. This lets a
garbage collector have a more correct view of the actually used
memory.
2000-04-17 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* garray.c, glib.h: Added g_(array|ptr_array|byte_array)_sized_new
functions, that reserve a certain amount of memeory for the array
at creation time to avoid reallocation. Fixes bug #6707 from
Charles Kerr <ckerr@osserver1.nssl.noaa.gov>.
2000-04-17 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h, gqueue.c, tests/queue-test.c (main): Renamed
g_queue_create to g_queue_new in conformance to all other GLib
data types.
2000-04-16 Damon Chaplin <damon@helixcode.com>
* tmpl/linked_lists_single.sgml:
* tmpl/linked_lists_double.sgml:
* tmpl/trees-nary.sgml: updated.
* tmpl/modules.sgml: described g_module_build_path().
* tmpl/date.sgml: made short description lower case and end in a '.'.
* glib-sections.txt: rearranged GDate section.
* tmpl/arrays.sgml:
* tmpl/arrays_byte.sgml:
* tmpl/arrays_pointer.sgml: updated.
2000-03-26 Tor Lillqvist <tml@iki.fi>
* README.win32: Tell about using the mingw-based gcc, which is
much easier than modifying the cygwin gcc to product mingw code
for the msvcrt runtime.
* makefile.cygwin.in (WIN32APIHEADERS): Kludge to make it work
with a "pure" mingw gcc, too.
2000-03-24 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* garray.c: Made GArray behave correct. Now zero_terminated really
means, that the element array->data[array->len] exists and is
zeroed, and clear means that any unassigned elements obtained
through g_array_set_size (the only way to get unassigned elements
AFAICT) are zeroed. Added some macors to mak the code more
obvoius. Also made GPtrArray zero elements after
g_ptr_array_set_size. This is done in a portbale way (assignment
of NULL instead of just memsetting it to zero), though that might
be more portability than we actually want.
2000-03-24 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* Makefile.am, gthread/Makefile.am, gmodule/Makefile.am,
tests/Makefile.am: Added various win32 related *.in files to
EXTRA_DIST to let 'make distcheck' procude all the corresponding
files, which it silently fails to do currently.
2000-03-23 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* 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 Jos 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
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.
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 (_g_module_symbol): do not return NULL symbols.
* gmodule-os2.c: removed NetBSD specific defines.
(_g_module_self): set an error message for unsupported behaviour.
* 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.
2000-03-04 Tor Lillqvist <tml@iki.fi>

G_MODULE_IMPL_WIN32, not G_OS_WIN32.
* gmoduleconf.h.win32: Remove LCC stuff from here, too.
