* makefile.{cygwin,msc}.in
* tests/makefile.{cygwin,msc}.in: Remove gstack and its test
program.
* glib.def: Additions and removals.
* README.win32: Improve gcc build instructions.

Sat Jul 24 20:11:35 1999 Tim Janik <timj@gtk.org>
* merged GLib 1.3.0 with glib-1.2.3 from Fri Jul 16 22:18:36.
* incorporated proposed cleanups from gtk-devel-list.
* bumped version number to GLib-1.3.1
* glib.h:
* gqueue.c:
* gstring.c:
* glist.c:
removed string tokenisation (we got g_strsplit() and g_strjoin()
already) and readline functions.
s/g_list_delete/g_list_delete_link.
implemented g_slist_delete_link.
removed notion of g_ATEXIT() macro in glib.h, this is an *internal*
macro, g_atexit() is provided for public consumption.
added GTrashStack inline utility functions.
reimplement double eneded queues.
removed GStack implementation, people can use a queue or a (singly)
linked list for this task.
deprecated g_strescape(), we need the SunOS variants here.
* gdate.c: added DEBUG_MSG() macro to wrap old messages.
* *.*: CVS merges.
* upgrade to libtool 1.3.3.
* README.win32: Correct URL for mingw runtime sources.
* build-dll: Combine commands with &&.
* glib.h: Map also rmdir() and hypot() for MSVCRT library.
* makefile.cygwin.in
* tests/makefile.cygwin.in: New DLL naming style. GCC-compiled DLLs are
now called *.gcc.dll, to avoid binary incompatibilities with
MSVC-compiled versions.
* makefile.msc.in: Cosmetics.
1999-07-07 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Test for pthread_join rather than for
pthread_create to determine the right thread-lib. Makes it work on
mips-sgi-irix6.5. Hitn from to Jari Vuoksenranta
<javu@piano.ux.phys.jyu.fi>.
1999-07-01 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in, acconfig.h, gutils.c: Added a g_memmove
replacement for platforms without memmove, where bcopy can't
handle overlapping copies and the corresponding checks, which is
taken form the PERL Configure routine.
* glib.h: Updated the commentary about g_memmove to be right and
more GLib-like.
* configure.in: Removed test for rand_r, as it isn't used anymore.
* 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.
* glib.h (Win32): Map fileno to _fileno for mingw32. Map fstat to
_fstat.
* README.win32: Advice also to remove -lmoldname from the
patch to the egcs-1.1.2 spec file patch.
* Makefile.am tests/Makefile.am: Correct rules for making the
win32-related files that are made from corresponding .in files.
Is there a cleaner way than explicitly writing rules that invoke
config.status?

New files, used to generate corresponding non-.in files when
making a dist. This is just so the version numbers will be kept in
synch automatically.
* configure.in: Also substitute @GLIB_MAJOR_VERSION@,
@GLIB_MINOR_VERSION@, and @GLIB_INTERFACE_AGE@.

not _MSC_VER.
* gstring.c: Include <io.h> on Win32 for _read prototype.
* gutils.c: Remove old IO channel code (was in #if 0).
* makefile.cygwin: Don't need to link with kernel32 and msvcrt
explicitly, they are included anyway.
i.e. gcc -mno-cygwin on cygwin (a.k.a. mingw32, using egcs-1.1.2).
* README.win32: Updated.
* build-dll makefile.cygwin tests/makefile.cygwin: New files.
* glib.h glib.def glibconfig.h.win32 makefile.msc: Slight updates.
* gmain.c: No need to include <fcntl.h> and <io.h> on Win32.

1999-04-22 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gutils.c (g_get_any_init): use sysconf (_SC_GETPW_R_SIZE_MAX) as
the new initinal bufsize for getpwuid_r on systems, that support
this. Hint from Holger Duerer <H.Duerer@zait.uni-bremen.de>.
Sat Apr 17 20:55:13 BST 1999 Tony Gale <gale@gtk.org>
* glib.h, gstring.c: Add new g_string functions for reading
from file/socket descriptors, and tokenising strings.
Added various g_string macros.
* README.win32: Mention the tests directory.
* glib.def: Add the functions from grand.c.
* glibconfig.h.win32: Add unsigned max values, and the format
strings.
* makefile.msc: Add grand.

1999-04-12 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h: Moved struct declaration up. Style fixes.
* grand.c: Style fixes. Only try to open /dev/random once.
* tests/rand-test.c (main): New tests; Slight bug fix.
1999-04-09 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* grand.c, tests/rand-test.c: New files to implement the Mersenne
Twister Pseudo Random Number Generator.
* glib.h, AUTHORS, Makefile.am, tests/Makefile.am: Changed
accordingly.
1999-03-30 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Added a check for the right format to printf and
scanf long longs. It is %qi instead of %lli on FreeBSD for
whatever reason.
* Makefile.am (glibconfig.h): Make sure `glibconfig.h' exists
after the rule is fired.
(install-exec-local): Install glibconfig.h only if the contents
are different from the currently installed glibconfig.h.
* config.h.win32: Update version numbers.
* glibconfig.h.win32: Update version numbers and pthreads-win32-
related magic values.
* README.win32: Some improvements.
* makefile.msc: Add gqueue and gstack. Correct version number.
1999-03-18 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: added new AC_SUBST(GTHREAD_COMPILE_IMPL_DEFINES)
to hold various defines to get the right thread implementation on
different platforms. Also look in -ldce for pthread_create. Should
make it work on HP-UX 10.x.
* gthread/Makefile.am (INCLUDES): Added @GTHREAD_COMPILE_IMPL_DEFINES@.
1999-03-17 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Added missing values for G_MAXU(SHORT|INT|LONG) on
platforms with only /usr/include/values.h.
* acconfig.h: Removed unnecessary macros.
* glibconfig.h.win32, config.h.win32: Moved G_THREADS_IMPL_POSIX
from config.h.win32 to glibconfig.h.win32. Taken from glib 1.2
branch.
* configure.in: Also accept _Pctime_r instead of ctime_r, while
seraching for the right `_REENTRANT' flag. This is for Digital
UNIX 4.0d. Taken from glib 1.2 branch.
Wed Mar 17 01:46:28 1999 Tim Janik <timj@gtk.org>
* merges from glib-1-2:
Sun Mar 14 17:50:35 1999 Tim Janik <timj@gtk.org>
* gmem.c (g_mem_chunk_*): changed a bunch of g_assert() statements
to g_return_if_fail().
(g_mem_profile):
(g_mem_chunk_print):
(g_mem_chunk_info): removed some extraneous "\n"s at the end of the log
messages.
* gtimer.c (g_timer_*): changed a bunch of g_assert() statements
to g_return_if_fail().
* grel.c (g_*): changed a bunch of g_assert() statements to
g_return_if_fail() and added some extra ones to check relation != NULL.
Tue Mar 9 23:25:50 1999 Tim Janik <timj@gtk.org>
* configure.in: check for working realloc (NULL,).
* gmem.c (g_realloc): use malloc() for initial allocation on systems
where realloc(NULL,) will not work (this is the case on SunOS, reported
by Tom Geiger).
Mon Mar 8 07:42:08 1999 Tim Janik <timj@gtk.org>
* ghook.c (g_hook_unref): when !hook_list->is_setup, wrap the
flag around the call to g_hook_free() to avoid spurious
warnings (happens during destruction phase).
1999-03-02 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gmem.c: Fixed a stupid cut'n'paste error of mine. Thanks to
Friedrich Dominicus <Friedrich.Dominicus@inka.de>
1999-03-16 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* tests/type-test.c: Added a test for the
G_(U)?INT(16|32|64)_FORMAT and G_(MIN|MAX|MAXU)(SHORT|INT|LONG)
macros.
1999-03-16 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Removed G_(U)?INT8_FORMAT again, as it can't be
used for scanf.
* configure.in: Added the macros G_MAXU(SHORT|INT|LONG). I do not
know how to handle these on platforms with /usr/include/values.h,
but without /usr/include/limits.h. Please someone add this.
1999-03-15 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Added the macros G_(U)?INT_(8|16|32|64)_FORMAT to
use for printf and (much more important) scanf format strings for
the corresponding GLib types.
* glib.h Added G_(U)?(SHORT|INT|LONG)_FORMAT for consistency. It
however makes no sense to also provide G_(FLOAT|DOUBLE)_FORMAT, as
they are different for printf (f for both) and scanf (f for float,
lf for double). Defining G_INT_FORMAT makes sense however, as we
might want to define gint to something different than int someday
in the future. Idea from Sascha Brawer <sb@adasys.ch>.
1999-03-14 Jeff Garzik <jgarzik@pobox.com>
* gdate.c:
Commented out debugging output.
* tests/Makefile.am, tests/date-test.c:
Added test of the GDate module, based closely on testgdate.c.
* tests/Makefile.am:
Bugfix - compile tests with @GLIB_DEBUG_FLAGS@.
* configure.in (glibconfig.h): Remove widechar tests and defines.
(fd_set): Change the grep for `fd_mask' to search for `fd_set'.
* gerror.c (fd_mask): Remove conditional typedef. It is not used
elsewhere in the file.
* gmain.c (fd_mask): Likewise.
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.
1999-03-01 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gutils.c (g_get_any_init): Fixed yet another bloody
implementation of getpwuid_r. This time for AIX. Thanks to Olaf
Dietsche <olaf.dietsche+list.gtk@netcologne.de>. I would like a
configure test better than that, but have no idea, how to do that
easily.
Sat Feb 27 01:18:47 1999 Tim Janik <timj@gtk.org>
* ChangeLog: moved old ChangeLog to ChangeLog.pre-1-2, and started
new one.
* configure.in: set glib version to 1.3.0.
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.
Thu Feb 18 08:24:12 1999 Tim Janik <timj@gtk.org>
* gmem.c (g_realloc): plugged a memory leak, reported by Koen D'Hondt
<ripley@xs4all.nl> on 15 Oct 1998. allocate inital block from realloc.
1999-02-15 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h, glibconfig.h.win32, configure.in: Changed signature of
all g_static_mutex_* functions to take a pointer rather than the
struct itself. This is not an issue at the moment, because those
funcs are really macros, but is it un'G'ish and might fall on our
feet in the future.
* gthread/testgthread.c (test_mutexes): Use new signature of
g_static_mutex* functions.
Wed Feb 10 12:06:30 1999 Tim Janik <timj@gtk.org>
* gmodule.c (CHECK_ERROR): be more descriptive on unsupported systems.
Wed Feb 10 12:01:42 1999 Tim Janik <timj@gtk.org>
* configure.in: don't reset G_MODULE_IMPL, so it can be overridden
from the command line.
Wed Feb 10 07:56:33 1999 Tim Janik <timj@gtk.org>
* gmodule.c (g_module_error): fixed errernerous code wrt to thread
specific error string allocation handling.
Wed Feb 10 06:20:30 1999 Tim Janik <timj@gtk.org>
* gmutex.c (g_static_private_set): invoke destroy notifier when
overwriting values, initialize new array fields with NULL.
(g_static_private_free_data): do not skip destroy notification for
data == NULL.
* gutils.c (g_direct_equal): compare pointer values directly instead
of just their guint values which is a loosing conversion for
sizeof(gpointer)==8 systems.
(g_get_any_init): restructured code so we don't use endless loops like
while (1), which boil down to an ugly alias for goto.
strip ,.* from the real name.
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.
Sun Feb 7 21:56:00 1999 Owen Taylor <otaylor@redhat.com>
* gmem.c (g_mem_profile): Copy all elements
of the allocations[] array, including the last.
(Pointed out by "Matthew W. Samsonoff" <mws7323@osfmail.isc.rit.edu>)
1999-02-05 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Make the error message in case of a broken thread
system a bit more informative.
* gutils.c (g_get_any_init): Changed the error logic again, now
only leaving the memory doubling loop, when success is reached or
when the user isn't found or when the buffer is 32k big,
additionally now getpwuid will be run, if getpwuid_r didn't work
out properly. A warning is issued however.
* gmessages.c (g_log_default_handler): (Win32:) Don't call
ensure_stdout_valid (which would open an unneeded console window)
if we're calling a logging function. Define ensure_stdout_valid
as an empty macro on Unix.
* gutils.c (g_get_any_init): (Win32:) Trust HOME first if defined,
then try HOMEDRIVE and HOMEPATH.
Mon Feb 1 19:04:28 1999 Owen Taylor <otaylor@redhat.com>
* gmain.c (g_main_iterate): Release the main_loop
lock around calls to prepare() and check() so
that we are not holding the main loop lock
over user code.
1999-01-30 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Moved the check for MT save function variants
after the determination of the MT cflags and use them there.
1999-01-28 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Simplified configure.in test for posix threads,
systems, that provide /usr/include/pthread.h should also have the
posix thread library. This is to avoid writing down all the tests
twice. New test for thread system on HPUX 11. Info from Matt
Nottingham <matt@sar.dera.gov.uk>.
* acinclude.m4: Xsed isn't valid here, don't use it
* ltmain.sh
* ltconfig: better file magic regexp for Linux libs
* gmodule/Makefile.am: arg, noinst_LTLIBRARIES doesn't make shared
libs, revert my previous change to this file
* docs/texinfo.tex: add it so automake doesn't whine
-Yosh
Wed Jan 27 01:57:19 1999 Tim Janik <timj@gtk.org>
* configure.in (G_MODULE_HAVE_DLERROR): applied patch from Andrej
Borsenkow <borsenkow.msk@sni.de> to also check for dlsym() in system
libraries and -ldl, to catch systems that provide dlopen() in libc
and dlsym() in libdl. this is at least the case for Reliant UNIX
5.44 (labeling itself as SINIX).
1999-01-26 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gdate.c (g_date_set_time): Removed the #warning about MT
unsafety without localtime_r.
* configure.in: Moved it here.
1999-01-25 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Do not use the thread libs, when searching for
some functions, as this might require glib to always be linked
with the thread libs on some platforms.
* gutils.c (g_get_any_init): Don't set errno to zero and use it
only as the error code, if the function returned a value less
0. It might happen, that the call succeeds, even though the errno
is set during the call (i.e. it first looks for a passwd file,
which is not found). Submitted by Michael Natterer
<mitschel@cs.tu-berlin.de>. BTW: Sorry for all the mess with that
`getpwuid_r' change, but it had to be done once.
Sun Jan 24 10:33:30 1999 Tim Janik <timj@gtk.org>
* gutils.c (g_get_any_init): reverted raja's changes, since they leaked
a struct passwd contents buffer and for the rest mostly substituted a
while loop with a bunch of gotos.
restored the getpwuid() code to what we had after my recent clean ups
("Sat Jan 23 02:14:28 1999 Tim Janik"), module yosh's recent changes.
to feature solaris behaviour of directly returning errno, we don't
modify error anymore if it's > 0 and simply reset errno.
don't reset g_home_dir for !NATIVE_WIN32 && !NATIVE_WIN32.
* gutils.c
(g_get_any_init) [HAVE_GETPWUID_R && HAVE_GETPWUID_R_POSIX]:
Hopefully got the error handling for `getpwuid_r' right.
(g_get_any_init) [HAVE_GETPWUID_R && !HAVE_GETPWUID_R_POSIX]:
Fix typo (change `pw == NULL' to `pw != NULL').
Please let this be right :-/.
Sun Jan 24 00:36:22 EST 1999 Jeff Garzik <jgarzik@pobox.com>
* ghash.c:
- Revert previous "fix" (which really just did things a
different way).
- (g_hash_table_remove): Don't need to support multiple values
for a single key.
* tests/hash-test.c:
Add test where hash function always returns a single value.
Add beginnings of tests for g_hash_table_foreach[_remove] and
g_hash_table_remove.
Sat Jan 23 22:45:59 1999 Jeff Garzik <jgarzik@pobox.com>
* ghash.c (g_hash_table_lookup_node, g_hash_table_lookup,
g_hash_table_insert, g_hash_table_remove,
g_hash_table_lookup_extended):
- Fixed bug that overwrote nodes in hash buckets instead of
adding them to the hash bucket node list.
Hash tables now work as advertised.
(g_hash_table_resize):
- Use g_new0 instead of manual init.
- Space out code a bit for readability.
(g_hash_nodes_destroy):
- Replaced "if (!hash_node) return;" with
"if (hash_node) {do stuff}".
Testing takes up less code space than explicit call to
'return' before end of function. (look at gcc -S)
Updated module header copyright to 1999.
New module macro G_HASH_BUCKET for (table,key)->bucket lookups.
* tests/hash-test.c:
- Add two new tests, one with strings as the keys and values, and
one with ints as the keys and values. Tests indirect (strings)
and direct (ints) hashing.
- Cleanup unused junk left over from testglib.c.
- Converted a g_print call to g_assert_not_reached.
- Updated copyright to 1999.
* testglib.c, tests/string-test.c:
- Init 'tmp_string' var to NULL, silencing uninit-var warning.
Sat Jan 23 02:14:28 1999 Tim Janik <timj@gtk.org>
* gutils.c (g_get_any_init): cleaned up the errno mess for
GETPWUID. we especially don't want to g_error() out here!
the warning for G_THREADS_ENABLED and !HAVE_GETPWUID_R isn't
gcc related.
if !HAVE_PWD_H and !NATIVE_WIN32, g_free the home dir before
resetting it to NULL, why are we doing this anyways?
reordered code a bit so we always provide defaults (except
for g_home_dir).
Thu Jan 21 12:40:11 EST 1999 Jeff Garzik <jgarzik@pobox.com>
* gmodule/gmodule-dl.c (_g_module_build_path):
Add braces to eliminate an ambiguous else warning.
* tests/{Makefile.am, string-test.c, strfunc-test.c}:
Separate string and strfunc tests, working towards goal of
having separate test for each of the GLib modules.
Add a couple GString length tests.
