* gutils.c (g_vsnprintf): When using the vsnprintf()
implementation, '\0'-terminate the resulting string
and return its length rather than -1.

1999-03-01 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gutils.c (g_get_any_init): Fixed yet another bloody
implementation of getpwuid_r on 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.
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.
1999-02-10 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h: s/G_LOCK_DECLARE/G_LOCK_DEFINE/ throuhout glib. Added
G_LOCK_EXTERN macro to declare a lock externally.
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.
1999-02-05 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.
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 :-/.
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).
1999-01-21 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gutils.c (g_get_any_init): Changed error handling again, as the
error is not always set in errno, it is the return value on some
systems. What an evil world.
Wed Jan 20 20:48:58 GMT 1999 Adam D. Moss <adam@gimp.org>
* gutils.c (g_get_any_init): All gtk apps were broken
here on my setup. I changed the error to a warning to at
least get things limping.
1999-01-20 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gutils.c (g_get_any_init): Use getpwuid_r with the right
signature, if available.
* configure.in, acconfig.h: Test for existance of getpwuid_r and
its signature.
* 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.
1999-01-07 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gutils.c (g_get_any_init): Here we must replace getpwuid by
getpwuid_r, but as I do not know how for now, I just made a FIXME
note ;-)
* gdate.c (g_date_set_time): localtime --> localtime_r to make it
thread safe.
* configure.in: We do not need to check for broken solaris mutex
intitializer any longer. Provide a macro to show the used thread
implementation. Not nice, but this is needed until thread support
is completed here inside glib.
* gthread/testgthread.c: conditionally compile according to the
G_THREADS_IMPL_??? macros.
(test_private_func): use rand_r instead of rand to make it
thread safe.
Wed Dec 16 03:16:58 1998 Tim Janik <timj@gtk.org>
* configure.in: version bump to 1.1.8, binary age 0, interface age 0.
* glib.h: changed g_lock() to G_LOCK(), g_unlock() to G_UNLOCK() and
g_trylock() to G_TRYLOCK(), since these are macros that expand to
nothing with --disable-threads.
changed G_LOCK_DEFINE() to G_LOCK_DECLARE() and introduced
G_LOCK_DECLARE_STATIC() to achive the results of static G_LOCK_DECLARE().
changed semantics of g_thread_supported to g_thread_supported() so it
can be used as a function like g_module_supported(). the actuall
definition is still a macro that expands into a variable for
performance reasons though.
various indentation and coding style cleanups.
* configure.in: added --enable-threads that defaults to yes.
* gmutex.c: changed tests g_thread_supported to g_thread_supported (),
changed variable settings of g_thread_supported
to g_threads_got_initialized.

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.
someone does the necessary updates.
Sat Nov 28 12:53:47 1998 Owen Taylor <otaylor@redhat.com>
* Makefile.am configure.in acconfig.h giochannel.c
glib.h glist.c gmain.c gutils.c:
- Revised GIOChannel to provide a generic virtual-function
based interface.
- Added unix fd-based GIOChannel's
- Added generic main-loop abstraction
- Added timeouts and idle functions using main-loop abstraction.

* applied glib-tml-981120-0, change log appended below.
* glibconfig.h.win32: passthrough 64-bit constants unchanged, VC++
infers them
Fri Nov 20 22:26:43 1998 Tor Lillqvist <tml@iki.fi>
* glib.h: Moved MSC pragmas from glib.h to glibconfig.h.win32.

-Yosh
* applied glib-tml-981101-1 patch from Tor Lillqvist (ChangeLog
entry appended below)
* testglib.c
* gstrfuncs.c
* glib.h: use G_HAVE_GINT64, since HAVE_GINT64 is gone
* gmessages.c
* gscanner.c: #include <config.h> in here too, for HAVE_UNISTD_H
-Yosh
* Makefile.am (glibconfig.h): New rule.
(stamp-gc-h): New rule. Generate `glibconfig.h'.
* configure.in (AM_CONFIG_HEADER): It is now `config.h'.
(HAVE_BROKEN_WCTYPE): On Solaris, look for iswalnum in -lw before
concluding "broken wctype".
(glibconfig.h): Use AC_OUTPUT_COMMANDS to put generation code into
config.status.
* glib.h: Remove a lot of tests and defines. All these have been
moved to `configure.in (glibconfig.h)'.
* gerror.c: Include <config.h>.
* gmem.c: Likewise.
* gstrfuncs.c: Likewise.
* gutils.c: Likewise.
This could cause some short term instability.
* glib.h: reimplemented the endian stuff, using inline asm for x86.
#define g_htonl and friends.
* testglib.c: new tests for the endian stuff
* configure.in: care for AIX in gmodule linker flags test (from Joel Becker
<jlbec@raleigh.ibm.com>). Check $host_os for linux instead of existance of
/usr/include/linux
* gutils.c: buh-bye evil warning. Thou hast been #ifdef'd out of thine
existance!
-Yosh
Tue Oct 27 03:00:50 1998 Tim Janik <timj@gtk.org>
* glib.h: removed dummy structure definitions for struct _GCache,
_GTree, _GTimer, _GMemChunk, _GListAllocator and _GStringChunk.
* gutils.c: implement glib's inline functions _after_ all include
statements have been processed.
removed Tor's MAXPATHLEN check since there already was one supplied
further down in this file.
(LibMain): special cased the #ifdef __LCC__ case for NATIVE_WIN32,
since lcc maybe used on other platforms as well. why in hell is this
stuff required?
(g_get_any_init): for windows, if the user name is supplied, use it as
realname also.
in general, if there is no homedir specified, use the tmpdir that
we already figured.
* gtimer.c (g_timer_elapsed): changed a g_assert() statement to
g_return_if_fail().
* applied glib-tml-981020-0.patch for WIN32 portability, added some
comments and g_return_if_fail() statements, minor indentation fixes.
ChangeLog entry from Tor Lillqvist is appended.
* glib.h (struct dirent): use lower case structure members.

s/COMPILING_GLIB/GLIB_COMPILATION/
1998-10-20: Tor Lillqvist <tml@iki.fi>
* README.win32 glib.def gmodule.def
* glibconfig.h.win32 gmodule/gmoduleconf.h.win32:
New files for the Windows port. The .def files list exported
symbols for the Microsoft linker and compatibles.
* configure.in:
Added checks for some platform-dependent headers: pwd.h sys/param.h
sys/select.h sys/time.h sys/times.h unistd.h, and the function lstat.
* gerror.c:
Conditionalized inclusion of system-dependent headers. Changes
for Windows: no gdb to do a stack trace. Just call abort().
* glib.h:
Changes for Windows:
Added macros G_DIR_SEPARATOR, G_DIR_SEPARATOR_S for
platform-dependent file name syntax elements. Added macros
G_SEARCHPATH_SEPARATOR, G_SEARCHPATH_SEPARATOR_S for
platform-dependent search path syntax conventions.
Added pragmas for Microsoft C to make it more pedantic.
Marked GLib's global variables for export from DLL.
Added the function g_strescape that escapes backslashes.
Added functions g_path_is_absolute and g_path_skip_root to
handle platform-dependent file name syntax.
Added the function g_getenv that expands environment variables
that contain references to other environment variables, as is
typical on Windows NT.
Added the GIOChannel structure which is used to encapsulate the
IPC mechanism used by the GIMP's plug-ins, and possibly other
things later. On Unix a GIOChannel encapsulates just a file
descriptor. On Windows it contains a file handle from _pipe() and a
few other things related to the implementation of gdk_input_add
and GIMP plug-in communication. Subject to change.
Removed duplicate declarations of the version variables.
For the Microsoft compiler, declare own implementation of
ftruncate and the <dirent.h> functions.
* gmem.c:
Define a symbolic name for the profiling table size.
* gmessages.c:
Conditionalized inclusion of unistd.h. On Windows, output using
stdio to stdout.
* gscanner.c:
Conditionalized inclusion of unistd.h. Added changes for
Microsoft C. Added CR to the skipped character set. Added small
workaround for MSC compiler bug in g_scanner_cur_value.
* gstrfuncs.c:
Added the function g_strescape, which escapes the backslash
character. Needed especially when printing Windows filenames.
* gtimer.c:
Conditionalized inclusion of unistd.h and sys/time.h. Added
implementations for Windows.
* gutils.c:
Conditionalized inclusion of platform-dependent headers. Use
the platform-independent file name syntax macros.
Conditionalize code on platform-dependent features. Added the
functions g_path_is_absolute g_path_skip_root and g_getenv.
Added the GIOChannel-related functions. Added
compiler-dependent Unix compatibility functions for Windows.
* makefile.lcc makefile.msc:
New files. Compiler-specific makefiles for LCC-Win32 and
Microsoft C. Only Microsoft C is actually supported currently.
* testglib.c:
Added pathname check cases for Windows. Added workaround for
bug in the Microsoft runtime library. Improved some tests a bit.
Tue Oct 27 04:00:11 1998 Tim Janik <timj@gtk.org>
* testgmodule.c (main): changed the #ifdef WIN32 test to NATIVE_WIN32,
this needs to be more constistent throughout the code, do we go for
NATIVE_WIN32 or WIN32?
* gmodule.c (LibMain): special cased the #ifdef __LCC__ case for
NATIVE_WIN32, since lcc maybe used on other platforms as well.
* libgplugin_a.c (LibMain):
* libgplugin_b.c (LibMain):
likewise. not sure i like this special requirement for lcc in here.
* gmodule-dl.c (_g_module_build_path):
feature empty "" directories and prepend the module name with "lib".
* gmodule-dld.c (_g_module_build_path):
* gmodule-win32.c (_g_module_build_path):
feature empty "" directories.
* we need some more magic in the _g_module_build_path variants
so we don't append/prepend lib and .so, .sl or .dll for those names
that already contain it.
* applied patch from Tor Lillqvist for g_module_build_path() and
windows support.
1998-10-20: Tor Lillqvist <tml@iki.fi>
* gmodule/gmodule-win32.c:
New file.
* gmodule/gmodule.c gmodule/gmodule.h:
Added the funcion g_module_build_path that builds the path to
a module file, decorating the name according to the system's
conventions. Added the Windows implementation.
* gmodule/libgplugin_a.c gmodule/libgplugin_b.c:
Added LibMain for LCC-Win32.
* gmodule/testgmodule.c:
Handle Windows dll names.
Tue Sep 8 05:04:06 1998 Tim Janik <timj@gtk.org>
* glib.h: abandon the use of ATEXIT(), we keep the fallback
macros for backwards compatibility. people ought to use g_atexit().
* gutils.c (g_atexit): new function to take over the implementation
of ATEXIT. this function is guarranteed to succeed, similar to
g_malloc().
Mon Sep 7 07:53:21 1998 Tim Janik <timj@gtk.org>
* configure.in: check for all three inline keywords individually.
* glib.h: inlining hassle. for compilers that don't allow the `inline'
keyword, mostly because of strict ANSI C compliance or dumbness, we try
to fall back to either `__inline__' or `__inline'.
we define G_CAN_INLINE, if the compiler seems to be actually *capable*
to do function inlining, in which case inline function bodys do make
sense. we also define G_INLINE_FUNC to properly export the function
prototypes if no inlinig can be performed. we special case most of the
stuff, so inline functions can have a normal implementation by defining
G_INLINE_FUNC to extern and G_CAN_INLINE to 1.
* ltconfig: (compiler PIC flag test): special case linux for non
aout systems to honour lcc's position independant code (cases
"linux*aout)" and "linux*)" got added). (this needs to go into
libtool which does an advanced test, checking for __LCC__).
* autogen.sh: take $CC=lcc into account by invoking automake with
--include-deps so lcc isn't scared by gcc's auto-dependancy
generation code. care about $ACLOCAL_FLAGS. optionally feature
autoheader.
* minor fixups in other places to cure some of lcc's warnings.
Mon Aug 24 02:08:56 1998 Tim Janik <timj@gtk.org>
* glib.h:
* gstring.c:
* gstrfuncs.c:
(g_vsprintf): removed this function which was not publically
exported in glib.h. to export it, it should have been named
differently in the first place, since its semantics differ from
vsprintf(). apart from that, it was a possible cause for
problems since it worked on a previously allocated memory area and
was used in a lot places of glib. exporting it would have been a
guararant for problems with threaded programs.
(g_printf_string_upper_bound): exported this function to return
a string size, guarranteed to be big enough to hold the fully
expanded format+args string. added 'q', 'L' and 'll' flag handling.
in fact, the newly allocated area is in most cases much bigger than
required.
(g_strdup_vprintf()): new function returning a newly allocated string
containing the contents of *format and associated args (size is
calculated with g_printf_string_upper_bound()).
(g_strdup_printf): new function which wraps g_strdup_vprintf().
* configure.in: check for va_copy() or __va_copy() alternatively.
check whether va_lists can be copyied by value.
* glib.h: provide a definition for G_VA_COPY.
* glib.h:
* gmessages.c:
(g_logv):
(g_vsnprintf):
pass va_lists by value, not by reference, since this causes problems
on platforms that implement va_list as as arrays. internaly, use
G_VA_COPY (new_arg, org_arg); va_end (new_arg); to produce a second
va_list variable, if multiple passes are required. changed all
callers.
* glib.h:
* gerror.h:
renamed g_debug() to g_on_error_query(), cleaned up a bit.
renamed g_stack_trace() to g_on_error_stack_trace() since both
functions cluttered different namespaces.
there is an appropriate comment in glib.h now that explains the
unix and gdb specific dependencies of both functions.
removed g_attach_process().
g_on_error_stack_trace() should probably be handled with caution,
i've seem several different linux versions (2.0.x) become unstable
after invokation of this function.
Sun Aug 16 20:28:27 1998 Tim Janik <timj@gtk.org>
* version bump to 1.1.3, binary age 0, interface age 0.
* glib.h: be nice to platforms that don't have gint64 and don't
issue #warning on every compilation. since glib doesn't require
gint64 itself, packages that need gint64 should test for this
themselves.
* glib.h:
* gutils.c: added a new function g_vsnprintf().
Fri Aug 14 16:41:53 1998 Tim Janik <timj@gtk.org>
* glib.h: added static inline functions for bit mask tests:
g_bit_nth_lsf, g_bit_nth_msf and g_bit_storage.
Fri Aug 13 14:23:37 1998 Tim Janik <timj@gtk.org>
* glib.h:
* gmessages.c:
revised the message handling system, which is now based on a new
mechanism g_log*. most of the assertment macros got adapted to
feature the new g_log() call with an additional specification of
the log level in a preprocessor macro G_LOG_DOMAIN. if G_LOG_DOMAIN
is undefined upon the includion of glib.h, it'll be defined with a
value of (NULL) and thus preserves the original bahaviour for
warning and error messages. the message handler setting functions
for g_warning, g_error and g_message are only provided for backwards
compatibility and might get removed somewhen.
* Makefile.am: feature the G_LOG_DOMAIN macro to set the log domain
to "GLib" upon compilation. we currently have to add this definition
to the DEFS variable.
* testglib.c: we need an ugly #undef G_LOG_DOMAIN at the start
of this file currently, since automake doesn't support per target
_CFLAGS yet.
* glib.h: changed some gints to gbooleans, made a few const corrections,
removed some superfluous G_STMT_START{}G_STMT_END wrappers, added some
in other required places.
* gnode.c:
(g_node_prepend):
(g_node_insert_before):
(g_node_insert):
(g_node_append_data):
(g_node_prepend_data):
(g_node_insert_data_before):
(g_node_insert_data):
(g_node_append):
return (node), so these macros/functions can be usefully chained with
g_node_new().
[GModule]
Fri Aug 14 02:24:39 1998 Tim Janik <timj@gtk.org>
* Makefile.am: feature the G_LOG_DOMAIN macro to set the log domain
to "GModule" upon compilation. we currently have to add this definition
to the DEFS variable.
* testgmodule.c: we need an ugly #undef G_LOG_DOMAIN at the start
of this file currently, since automake doesn't support per target
_CFLAGS yet.
Tue Aug 4 15:17:54 1998 Tim Janik <timj@gtk.org>
* configure.in: version bump to 1.1.1, binary age 1, interface age 0.
* NEWS: updates.
* README: updates.
* INSTALL: updates and fixes.
* COPYING: include the GNU LGPL, rather than shipping an empty file.
* AUTHORS: listed original authors here, and added people who made
significant improvements to glib.
* glib.h:
* gutils.c: implement g_get_current_dir() which returns a newly
allocated string, instead of a g_getcwd() variant that operates
on a static buffer.
export glib_interface_age and glib_binary_age.
as a convenience, macro definitions have been added for
g_node_insert_data, g_node_insert_data_before, g_node_append_data and
g_node_prepend_data.
* testglib.c: minor cleanups, print current dir.
Fri Jul 10 06:33:43 1998 Tim Janik <timj@gtk.org>
* glib.h:
* gutils.h: added a bunch of utility/wrapper functions:
g_basename(), g_getcwd(), g_get_user_name(), g_get_real_name(),
g_get_home_dir(), g_get_tmp_dir(), g_get_prgname() and g_set_prgname().
* gutils.c: removed all g_str* functions.
* gstrfuncs.c: moved the bunch g_str* functions from gutils.c in this
place. this file shall never include <stdlib.h> to avoid clashes for
some of the g_str* functions on some OSes.
Fri Jun 12 00:39:28 1998 Josh MacDonald <jmacd@icw.EECS.Berkeley.EDU>
* glib.h: add new hash and equal functions g_int_*. complement
g_direct_hash with g_direct_equal.
* grel.c: new file, GRelations implement tuples of N-N mappings.
A comment in glib.h briefly describes the interface.
* ghash.c: new function, g_hash_table_size
* glib.h: new typedefs, gsize, gssize, gtime.
* garray.c: new functions implementing a simplified GArray. This
GPtrArray is an array of gpointers and has functions to add and
remove elements, much like java.lang.Vector.
* garray.c: new functions for the single-byte special case of
