* glib/gutils.h: Wrapping atexit() is a bad idea on Windows, where
the EXE and each DLL have their own atexit function chains.
#define g_atexit as atexit instead. This means it has a
better chance of doing what the caller wants. For instance,
gtkhtml calls g_atexit() registering a function in gtkhtml
itself. This caused a crash when g_atexit() was implemented as a
function in the GLib DLL. The gtkhtml DLL was already unloaded by
the time the GLib DLL got unloaded.
* glib/gutils.c: #undef the #define mentioned above, to also get a
real g_atexit() into the DLL for backward compatibility. Document
the Windows behaviour of g_atexit(), and document the varying ways
atexit() can behave in the context of dynamically loaded modules
on Unix.

Make also the g_spawn*() functions take parameters in the GLib
file name encoding, i.e. UTF-8, on Windows. Has no impact on Unix
API or ABI. Like the other GLib API that was earlier changed to
use UTF-8 on Windows, the names of the functions that take UTF-8
have _utf8 suffixes added by using preprocessor macros in the
header file. The old names are kept for functions with the old
behaviour, taking parameters in the system codepage, for DLL ABI
stability.
* glib/gspawn.h: On Win32 add the suffix _utf8 to the names of the
g_spawn*() functions.
* glib/gspawn-win32.c: Use wide-char API on NT-based
Windows. Convert parameters from UTF-8 to wide chars (NT) or
system codepage (Win9x) and call the C library _wspawn*() or
spawn*() functions respectvely. Add DLL ABI stability versions
that take parameters in the system codepage.
* glib/gspawn-win32-helper.c: On NT-based Windows use the
wide-char versions of argv and envp, and use wide-char API to
change directory and spawn the program to run. Remove the verbose
debugging output, it was too complex to modify for the wide-char
features. (Just add temporary debugging printouts if needed, no
need to have them permanently in the source.)
* glib/gspawn.c: Corresponding documentation updates.
* glib/glib.symbols: Corresponding changes: Mark the ABI stability
symbols as PRIVATE, add the new _utf8-suffixed ones.
2005-08-17 Matthias Clasen <mclasen@redhat.com>
* configure.in: Check for crt_externs.h and _NSGetEnviron.
* glib/gutils.c: On Darwin, include crt-externs.h and
define environ using _NSGetEnviron(). (#313731)
2005-08-16 Stepan Kasal <kasal@ucw.cz>
* glib/gutils.c (g_get_any_init): Move the body of the big if...
(g_get_any_init_do): ... to this new function.
(g_get_any_init): Declare as inline.
(g_get_any_init_locked): New inline function, does the locking.
Make use of these two throughout the code.
2005-08-15 Matthias Clasen <mclasen@redhat.com>
* glib/gbacktrace.c (g_on_error_stack_trace): Wait for
the child process and then simply return. This makes
The "S" option work as documented in g_on_error_query().
(#313125, Matthew F. Barnes)
* gobject/genums.c: (g_flags_get_first_value): Special-case flag
value of 0. Instead of returning the first random GFlagsValue
we come across, return the GFlagsValue for 0 if it exists or
NULL if it does not exist. Never return the GFlagsValue for 0
if the requested flags value is nonzero.
2005-08-10 Matthias Clasen <mclasen@redhat.com>
* glib/gfileutils.c (g_build_path_va, g_build_pathname_va):
Take a va_list*, not a va_list, to avoid compiler warnings
about uninitialized variables.
2005-08-09 Matthias Clasen <mclasen@redhat.com>
* tests/gobject/Makefile.am (test_programs): Add it here.
* tests/gobject/gvalue-test.c: Beginning of a test suite
for GValue.
2005-08-08 Matthias Clasen <mclasen@redhat.com>
* tests/convert-test.c: Enable the endianness test.
* glib/gconvert.c: Make the caching of iconv descriptors
optional.
* configure.in: Add an --enable-iconv-cache option, and
default to disabling iconv caching on new enough glibc.
Somebody with access to Solaris systems will need to test
if opening/closing of iconv descriptors is enough of
a performance problem to warrant the caching on that
platform. Note that the caching is causing correctness
problems in some corner cases, thus turning it off
is desirable unless it has severe performance implications.
2005-08-08 Matthias Clasen <mclasen@redhat.com>
* tests/Makefile.am: Add convert-test here.
* tests/convert-test.c: Add the beginning of a testsuite
for g_convert() and friends.
2005-08-04 Matthias Clasen <mclasen@redhat.com>
* glib/glib.symbols:
* glib/gatomic.[hc]: Always export g_atomic_int_get and
g_atomic_pointer_get as functions, even if we have macros,
to avoid changing the ABI depending on configuration.
* glib/gatomic.c: Fix the s390 implementations of
g_atomic_pointer_compare_and_exchange.
2005-08-04 Tor Lillqvist <tml@novell.com>
* glib/gstdio.h: Move the G_BEGIN_DECLS/G_END_DECLS pair outside
the #if/#else/#endif block. Otherwise we had G_BEGIN_DECLS without
matching G_END_DECLS on Unix, and G_END_DECLS without matching
G_BEGIN_DECLS on Win32.
2005-08-02 Matthias Clasen <mclasen@redhat.com>
* glib/gconvert.c (g_convert_with_iconv): Don't go in an
infinite loop if the input text ends in an incomplete multibyte
character. (#312402, Sebastian Bacher)
2005-08-02 Tor Lillqvist <tml@novell.com>
* tests/refcount/objects.c
* tests/refcount/properties.c
* tests/refcount/signals.c: Use g_usleep() instead of sleep() for
portability.
Mon Aug 1 23:33:47 2005 Tim Janik <timj@imendio.com>
* tests/refcount/closures.c: test high contention on closure
reference counts to trigger and catch non-atomic updates.
* tests/refcount/objects.c:
* tests/refcount/objects2.c:
* tests/refcount/properties.c:
* tests/refcount/properties2.c:
* tests/refcount/signals.c:
fixed up test and threading fundamentals. variables accessed from all
threads need to be volatile. context switches are enforced by using
g_thread_yield(), not g_usleep(1) which may result in busy waits on
some platforms. for testcode, always consider all warnings and
critical messages fatal. issue the currently running program on
stdout. improved progress indicators.
* tests/refcount/properties.c:
* tests/refcount/objects.c:
don't overdo the number of testing threads to keep the testing machine
usable, 2 threads can produce as much contention as 20 if executing the
same code.
* tests/refcount/signals.c: only start 1 thread per object. GObject
doesn't provide mutually exclusive object access, but only mutually
exclusive reference count modification.
* tests/Makefile.am: added closures test.
2005-08-01 Tor Lillqvist <tml@novell.com>
* tests/uri-test.c: Make it pass on Win32.
(from_uri_tests[]): Take into consideration that on Win32 we don't
return "localhost" hostnames.
(safe_strcmp_filename): New function that considers slash and
backslash equal on Win32.
(run_roundtrip_tests): Use safe_strcmp_filename().
Sun Jul 31 01:50:20 2005 Tim Janik <timj@gtk.org>
* glib/gdataset.c:
moved G_DATALIST_*_POINTER() macros here, because proper use requires
the global g_dataset_global mutex to be acquired.
g_datalist_id_get_data():
g_datalist_unset_flags():
g_datalist_set_flags(): properly acquire and release dataset mutex.
* glib/gdatasetprivate.h: implement G_DATALIST_GET_FLAGS() via atomic
pointer access to account for memory barriers. moved all other macros.
2005-07-26 Matthias Clasen <mclasen@redhat.com>
* configure.in: Try -mt as compiler flag for threads, needed
for the HP C compiler on HP-UX. (#163051, Paul Cornett)
2005-07-20 Matthias Clasen <mclasen@redhat.com>
* glib/gthreadpool.c (g_thread_pool_free): Don't get
stuck in here if immediate is TRUE. (#310954,
Hong Jen Yee)
* tests/threadpool-test.c (main): Test immediate == TRUE.
2005-07-20 Tor Lillqvist <tml@novell.com>
* glib/gutils.h (g_win32_get_system_data_dirs): Make this an
inline function. Define it only if G_CAN_INLINE and not
C++. (#173098)
2005-07-19 Matthias Clasen <mclasen@redhat.com>
* glib/gstring.c (g_string_chunk_insert_len): Avoid
an unnecessary strlen if len is -1. (#169692,
Benoit Dejean)
2005-07-15 Matthias Clasen <mclasen@redhat.com>
Make refcounting threadsafe by using atomic
operations. (#166020, Wim Taymans)
* gobject.c: Use a recursive lock to protect the
notify queue.
(g_object_unref): Get rid of g_object_last_unref and
do the last unref handling in g_object_unref.
(g_object_ref, g_object_unref): Use atomic operations.
* gsignal.c (struct _HandlerMatch): Use a full integer
for the ref_count field.
(handler_ref, handler_unref_R): Use atomic operations.
* gparam.c (g_param_spec_ref, g_param_spec_unref):
Use atomic operations instead of a lock to make the
refcounting threadsafe.
* gclosure.c (g_closure_ref, g_closure_unref): Use atomic
operations. This is more complicated here, since the
refcount is stored in a bitfield, so we also have
to access all other bitfield members atomically.
* gsignal.c (handlers_find): Read the meta_marshal flag
of the closure atomically.
* tests/Makefile.am (SUBDIRS): Add tests/refcount
* configure.in: Add tests/refcount
* tests/refcount/properties.c: Test property changes
from multiple threads.
* tests/refcount/signals.c: Test signal emission from
multiple threads.
* tests/refcount/objects.c: Test refcounting from
multiple threads.
* tests/refcount/objects2.c:
* tests/refcount/properties2.c: Tests to measure the
overhead of threadsafe refcounting.
* glib/giochannel.c (g_io_channel_ref, g_io_channel_unref):
Use atomic operations to make refcounting
threadsafe. (#166020, Wim Taymans)
2005-07-12 Matthias Clasen <mclasen@redhat.com>
* glib/goption.h (G_OPTION_FLAG_NOALIAS):
* glib/goption.c: Add and implement a new flag
to turn off the automatic <groupname>- prefixing
for conflict resolution of long option names. (#171840,
Adam McLaurin)
All optional callback arguments (#308886, Pawel
Sliwowski)
* glib/goption.h (G_OPTION_FLAG_OPTIONAL_ARG):
* glib/goption.c: Add and implement a new flag
to indicate that a callback *optionally* takes another
argument.
* tests/option-test.c: Add tests for optional arguments.
2005-07-10 Matthias Clasen <mclasen@redhat.com>
* glib/gutils.c (g_listenv): Ignore anomalous environment
entries which are not of the form variable=value. (#309859,
Morten Welinder)
2005-07-09 Tor Lillqvist <tml@novell.com>
* configure.in: Don't use autoconf variables for the resource
object files on Win32 any longer. Instead handle that in the
Makefile.am files. Check for windres.
* glibconfig.h.win32.in: Minor tuning to match the
configure-produced glibconfig.h closely.
* */Makefile.am: Don't use the scripts in build/win32 to
compile the .rc file into a resource object file. (This means
we loose the build number increment magic, but I doubt it was
that useful anyway.) Instead use windres directly. To pass the
normal .o file produced by windres through libtool, which
wants .lo files, pass it directly to the linker using a -Wl
option.
* */*.rc.in: Thus replace BUILDNUMBER with 0.
2005-07-01 Hans Breuer <hans@breuer.org>
* glib/gmessages.c : include <process.h> for getpid()
* glib/gmappedfile.c : include <io.h> for close() etc.
* glib/makefile.msc.in : add gmappedfile.obj
2005-07-01 Matthias Clasen <mclasen@redhat.com>
* glib/gkeyfile.c (g_key_file_get_key_comment):
(g_key_file_get_top_comment): Don't reverse the order of multiline
comments.
(g_key_file_get_group_comment): Actually get the group comment.
* tests/keyfile-test.c (test_comments): Test that comments are
handled properly. (#309263, Mikael Magnusson)
2005-07-01 Matthias Clasen <mclasen@redhat.com>
* tests/keyfile-test.c (test_comments): Test that comments are
handled properly. (#309263, Mikael Magnusson)
2005-06-30 Matthias Clasen <mclasen@redhat.com>
Apply a patch which may make GLib work on BeOS again.
(#309157, Kian Duffy)
* glib/gmain.c: Update the BeOS includes.
* glib/gstdio.c:
* glib/gutils.c (g_find_program_in_path):
* glib/gbacktrace.c (g_on_error_stack_trace): Use the UNIX
implementation on BeOS, as well.
* configure.in: Don't put glib 1.0 into G_MODULE_LIBS, even
on BeOS.
2005-06-26 Tor Lillqvist <tml@novell.com>
* glib/Makefile.am: libtool installs/uninstalls the import
library, no need to do it ourselves. Do still install/uninstall
the .def file, though.
* glib/gmappedfile.c: Add Win32 implementation.
(g_mapped_file_free): Don't mention writable shared mappings in
the doc comment. Free the GMappedFile struct.
* tests/mapping-test.c (main): No kill() or SIGUSR1 on Win32, use
a flag file instead to stop the child. Use g_usleep() instead of
sleep().
2005-06-24 Matthias Clasen <mclasen@redhat.com>
Add an mmap() wrapper called GMappedFile. (#148218,
David Schleef, Behdad Esfahbod)
* glib/gmappedfile.[hc]: New files.
* configure.in: Check for mmap.
* glib/Makefile.am: Add new files.
* glib/glib.symbols: Add new functions.
* glib/glib.h: Include gmappedfile.h
* tests/mapping-test.c: Tests for GMappedFile.
* tests/Makefile.am: Add new file.
2005-06-24 Tor Lillqvist <tml@novell.com>
* glib/Makefile.am
* gmodule/Makefile.am
* gobject/Makefile.am: Current GNU tools do understand the
PRIVATE keyword.
* glib/gfileutils.c (g_mkdir_with_parents): Return error with
EINVAL also for empty pathnames.
(g_build_pathname_va): Fix typo.
Thu Jun 23 15:52:08 2005 Manish Singh <yosh@gimp.org>
* glib/gfileutils.c: g_build_filename_va is only use in the G_OS_WIN32
case, so compile it conditionally.
