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)
2005-07-11 Matthias Clasen <mclasen@redhat.com>
* gobject.h:
* gobject.symbols: Remove G_GNUC_NULL_TERMINATED from
g_object_new again, since that makes gcc warn on calls of
the form g_object_new (some_type, NULL)
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.
2005-06-26 Tor Lillqvist <tml@novell.com>
* Makefile.am: libtool installs/uninstalls the import library, no
need to do it ourselves. Do still install/uninstall the .def file,
though.
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.
2005-06-13 Matthias Clasen <mclasen@redhat.com>
* gparam.h (GParamFlags): Re-add G_PARAM_PRIVATE as a
deprecated name for bit 5, since some language bindings
have it bound.
2005-05-20 Matthias Clasen <mclasen@redhat.com>
* gvaluetypes.c (g_value_set_string): dup the new value
before freeing the old, just in case. (#172142, Morten
Welinder)
2005-05-05 Owen Taylor <otaylor@redhat.com>
* gobject.[ch] gobject.symbols: Add
g_object_add/remove_toggle_ref() functions to get notification
when a reference count is the last remaining reference; this
enables better memory management for language bindings.
(http://mail.gnome.org/archives/gtk-devel-list/2005-April/msg00095.html)
2005-05-05 Owen Taylor <otaylor@redhat.com>
* glib/gdataset.[ch] glib/gdatasetprivate.h: Add
g_datalist_set/unset_flags(), g_datalist_get_flags() functions
to squeeze some bits into a GDataSet... this is needed for
efficient implementation of toggle references in GObject.
* tests/gobject/references.c tests/gobject/Makefile.am:
Add a test case for weak and toggle references.
* glib/gfileutils.[ch]: Rename g_file_replace() back
to g_file_set_contents().
* glib/glib.symbols: Update.
2005-05-05 Owen Taylor <otaylor@redhat.com>
* glib/Makefile.am glib/glib-sections.txt gobject/gobject-sections.txt:
Update
* gobject/tmpl/objects.sgml: Document toggle-references.
2005-03-25 Matthias Clasen <mclasen@redhat.com>
* gparam.c (param_spec_ht_lookup): Don't do the second
lookup if the name was already canonical. (#171502, Morten
Welinder)
2005-03-14 Matthias Clasen <mclasen@redhat.com>
* abicheck.sh: Make work again.
* gsourceclosure.c: Fix a typo.
Make PLT-reduction work with gcc4, and don't include
everything in gobjectalias.h:
* gobject.symbols: Group symbols by header and source
file.
* makegobjectalias.pl: Protect definitions by the same
preprocessor symbols used to guard the headers. Move
the alias declarations to a separate file which is
produced when calling makegalias.pl -def
* Makefile.am (gobjectaliasdef.c): Add a rule to
build this file.
* *.c: Include gobjectalias.h after the other i
GLib headers, include gobjectaliasdef.c at the bottom.
2005-02-24 Tor Lillqvist <tml@novell.com>
* Makefile.am (BUILT_EXTRA_DIST): Don't distribute
glib.def. (#167496, J. Ali Harlow)
* gobject/Makefile.am (EXTRA_DIST): Don't distribute
gobject.def. (#167496, J. Ali Harlow)
Sun Feb 6 22:00:46 2005 Manish Singh <yosh@gimp.org>
* abicheck.sh: feed the contents of config.h and glibconfig.h
into the preprocessor, since glib.symbols could need #defines
from them.
2004-12-27 Matthias Clasen <mclasen@redhat.com>
* configure.in: Add an OS_LINUX conditional.
* glib/Makefile.am (TESTS): Only check the ABI on
linux, since the shell script is not portable, and libtool
deficiencies may distort the ABI on other platforms. (#161741)
2004-11-30 Tor Lillqvist <tml@iki.fi>
* glib/Makefile.am (glib.def)
* gobject/Makefile.am (gobject.def): gcc -E complains "linker
unused because linking not done" if told to preprocess an
*.symbols file. Use '-' and redirection to pass it as standard
input instead.
Sun Nov 28 01:37:54 2004 <timj@birnet.org>
* gsignal.c: applied patch by sven@gimp.org (#153727) to reduce
signal connection complexity from O(n_handlers) to O(1).
2004-11-23 Matthias Clasen <mclasen@redhat.com>
Fix a problem with the PLT reduction changes which caused the
internal aliases to lose all attributes.
* glib/glib.symbols: Add attribute annotations.
* glib/makegalias.pl: Keep attribute annotations, but strip PRIVATE.
* glib/Makefile.am (glib.def): Strip attribute annotations, but keep
PRIVATE.
Mon Nov 8 10:47:41 2004 Manish Singh <yosh@gimp.org>
* gobject/gsourceclosure.c: removed wrap_g_io_channel_ref() hack,
since g_io_channel_ref() has a compatible API now.
2004-10-26 Matthias Clasen <mclasen@redhat.com>
* glib/glib.symbols: Add new symbols.
* abicheck.sh: Don't include symbols which are just in the
symbols list for .defs file compatibility.
2004-10-23 Matthias Clasen <mclasen@redhat.com>
* gtype.h (GTypeInterfaceCheckFunc): Rename first parameter to
check_data, since apparently the system headers on AIX leak a
macro named func_data. (#155178, Andrea Campi)
Wed Oct 6 02:12:44 2004 <timj@birnet.org>
* gtype.c (g_type_instance_get_private): applied patch from Jean-Yves
Lefort <jylefort@brutele.be> to not access the instance_real_class_bsa
pointer without holding the instance_real_class lock.
2004-10-04 Matthias Clasen <mclasen@redhat.com>
* gsignal.c (g_signal_add_emission_hook): Improve the warning
if G_SIGNAL_NO_HOOKS is set. (#154299, Nickolay V. Shmyrev)
2004-09-22 Tor Lillqvist <tml@iki.fi>
* Makefile.am (install-libtool-import-lib): [Win32] Add code to
remove the bug-compatibility entries (see #134813, and related
comments below) from the import library. The PRIVATE keyword in
the .def file is supposed to mean that, but it isn't implemented
yet by GNU ld.
* makegobjectalias.pl: In case the symbol is followed by some
stuff ("PRIVATE") that's intended for the .def file, use just the
actual symbol.
* gobject.symbols: For binary bug compatibility on Win32, add the
g_slist_remove_all and g_unichar_validate symbols inside #ifdef
INCLUDE_INTERNAL_SYMBOLS. (See #134813 and log entries from March
below.)
