Mon Aug 1 23:00:42 2005 Tim Janik <timj@imendio.com>
* gclosure.c: turned all modifications to the first 32 integer bits in a
closure into atomic accesses. wrapped write accesses into special macros
to keep the atomic modification logic in a single place. comment cleanups.
* gclosure.h: made all atomicly accessed closure fields volatile.
* gobject.h: made ref_count field volatile.
Sun Jul 31 02:04:23 2005 Tim Janik <timj@gtk.org>
* gobject.c: use g_datalist_set_flags() and g_datalist_unset_flags() to
allow proper locking around &qdata modifications.
Sat Jul 30 21:10:26 2005 Tim Janik <timj@gtk.org>
* gobject.c: reverted notify_mutex introduction, since this prevents
parallelized setting of object properties on different objects, and
serves no apparent purpose (to me at least).
g_object_real_dispose(): removed non-atomic reference count
modifications.
g_object_unref(): make sure the closures array is destroyed when
destroying signal handlers.
* gparam.c: cosmetic changes.
* gsignal.c: comment fixup. allow 16bit blocking count.
* gsignal.c: reverted GClosure related changes.
* gclosure.c: reverted premature commit of atomic reference
counting attempt.
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)
2005-05-05 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().

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.
2004-09-16 Matthias Clasen <mclasen@redhat.com>
Implement the same PLT reduction technique used in GTK+:
* Makefile.am: Generate gobjectalias.h from gobject.symbols.
(BUILT_SOURCES): Add gobjectalias.h.
* makegobjectalias.pl: Script to generate gobjectalias.h.
* *.c: Include gobjectalias.h
Sat Nov 29 14:57:20 2003 Tim Janik <timj@gtk.org>
* gobject.c: fix g_object_set() whithin _init() implementations
not working for construct-only properties.
(g_object_init): make the object enter a construct_objects list.
(g_object_newv): remove object from construct_objects after creation.
(g_object_set_valist):
(g_object_set_property): allow construct-only properties for
objects which are in construct_objects.
Thu Nov 27 17:53:52 2003 Tim Janik <timj@gtk.org>

(g_type_class_peek_static): variant of class_peek() which works for
static types only.
* gobject.c:
(g_object_do_class_init): make ::notify a run-action signal.
(g_object_newv): use g_type_class_peek_static() by default to
speed up common code path (trades two write-locks for one read-lock).
(g_object_disconnect):
(g_object_connect): allow signal specification words to be
seperated by '-'.
(g_object_set_valist):
(g_object_new_valist): don't leak values.
(g_object_get_property): check property for readability.
(g_object_set_property): check property for writability and to
not be construct-only.
(g_object_set_valist): check property to not be construct-only.
Tue Oct 14 17:40:19 2003 Owen Taylor <otaylor@redhat.com>
* gparamspecs.[ch]: Add a new GParamSpecOverride type
that is a pointer to a different paramspec in a parent
class or interface.
* gparam.[ch]: Add g_paramspec_get_redirect_target()
which follows GParamSpecOverride to the real property.
Make g_param_spec_pool_list() hand redirections,
properties on interfaces.
* gobject.[ch] gobjectnotifyqueue.c: Add
g_object_interface_install_property,
g_object_interface_find_property,
g_object_interface_list_properties(). Redirect virtually all
publically exposed GParamSpec's to the redirect target if
any. (->constructor is the exception.)
(#105894)
2003-09-12 Matthias Clasen <maclas@gmx.de>
Make the g_value_set_x_take_ownership() functions "official"
part of the API (#100948):
* gvaluetypes.[hc]: Add g_value_take_string() (synonym to the
now deprecated g_value_set_string_take_ownership()).
* gparam.[hc]: Add g_value_take_param() (synonym to the
now deprecated g_value_set_param_take_ownership()).
* gobject.[hc]: Add g_value_take_object() (synonym to the
now deprecated g_value_set_object_take_ownership()).

now deprecated g_value_set_boxed_take_ownership()).
* gobject/gobject-sections.txt: Add new g_value_take_x() functions.
* gobject/tmpl/param_value_types.sgml: Document new g_value_take_x()
functions. (#100948)
Fri May 30 14:42:24 2003 Owen Taylor <otaylor@redhat.com>
* gobject.c (g_value_set_object): Order refs/unrefs
so setting the same object back is safe. (#112861,
Morten Welinder)
Mon May 6 16:06:23 2002 Owen Taylor <otaylor@redhat.com>
[ merged from stable ]
* gobject.c: Remove PROPERTIES_CHANGED enumeration
value that wasn't used any more. (#78833,
Matthias Clasen)

that no longer exists. (#80814, Daniel Elstner)
Sun Mar 3 04:11:58 2002 Tim Janik <timj@gtk.org>
* gobject.c: placed a comment about not changing CArray until we have
g_object_list_watched_closures().
* gparam.h (struct _GParamSpecClass): added padding.
* gobjectnotifyqueue.c (struct _GObjectNotifyQueue): abuse
g_list_alloc() to allocate GObjectNotifyQueue to et rid
of locking issues.
Wed Feb 20 22:55:15 2002 Owen Taylor <otaylor@redhat.com>
* gobject.c: Fix implicit conversions between void * and
function pointer (Miroslaw Dobrzanski-Neumann, #71963)
Sun Feb 16 22:08:48 2002 Tim Janik <timj@gtk.org>
* gobject.[hc]:
* gparam.[hc]: provide marshaller specific value_set_*_take_ownership()
variants.
* gvalue.h: shrink GValue's data contents to 2 unions.
* glib-genmarshal.c: fix release and realeas_check hackage by always
using _take_ownership() variants. directly access value contents if
G_ENABLE_DEBUG is not defined.
* gobject.h: add padding pointers to the class struct.
Mon Sep 10 20:31:37 2001 Tim Janik <timj@gtk.org>
* gobject.[hc]: removed extraneous GObject* returns from a
couple functions that are very unlikely to be used in nested.
changed gpointer->GObject* for a couple return values/arguments.
this fixes#50206.
2001-08-17 James Henstridge <james@daa.com.au>
* gobject.c (WeakRefStack): add an object member to the structure.
(weak_refs_notify): pass wstack->object as extra argument to
notify functions.
(g_object_weak_ref): set wstack->object when initialising
WeakRefStack.
* gobject.h (GWeakNotify): add second argument to prototype which
gives the pointer to where the object that is being disposed of
was.
2001-08-06 Sven Neumann <sven@gimp.org>
* glib/gutils.[ch]: added new function g_nullify_pointer().
* gobject/gobject.[ch]:
added new functions g_object_[add|remove]_weak_pointer().
Mon Jul 2 07:17:47 2001 Tim Janik <timj@gtk.org>
* gobject.c (g_object_weak_ref):
(g_object_watch_closure): congrats tim, introducing of-by-one
errors like on my very first day of C programming.
Sat Jun 30 23:14:32 2001 Tim Janik <timj@gtk.org>
* glib/glist.[hc]: added g_list_insert_before().
* glib/gslist.c (g_slist_insert_before): provide an implementation,
prototype was already present...
Sat Jun 30 11:07:00 2001 Tim Janik <timj@gtk.org>
* gobject.[hc]: provide weak_ref/weak_unref functions,
invoked from ->dispose. renamed ->shutdown() to ->dispose(),
provide "public" API entry here: g_object_run_dispose(), this
fucntion should _only_ be called from object system implementations
(e.g. gtkobject.c) if at all.
* gtypemodule.c (g_type_module_dispose): s/shutdown/dispose/
* gsignal.h: removed compat aliases.
* gobject.c (g_object_connect): support data objects.
Thu Jun 28 16:57:44 2001 Tim Janik <timj@gtk.org>
* configure.in (GLIB_MICRO_VERSION): up version number to 1.3.7,
interface age 0, binary age 0.
Thu Jun 28 16:42:49 2001 Tim Janik <timj@gtk.org>
* gsignal.c (g_signal_lookup):
(g_signal_list_ids): give elaborate warnings about invalid types,
non-instantiatable types and unloaded types that we can't operate on.
* gparam.[hc]: g_param_spec_pool_belongings() ->
g_param_spec_pool_list_owned().
* gsignal.[hc]: renamed:
g_signal_newc -> g_signal_new
g_signal_disconnect_by_func -> g_signal_handlers_disconnect_by_func
g_signal_block_by_func -> g_signal_handlers_block_by_func
g_signal_unblock_by_func -> g_signal_handlers_unblock_by_func
added GConnectType to simplify (..gboolean swapped, gboolean after)
args.
* gobject.[hc]: changed prototypes accordingly.
Mon Jun 11 17:07:06 2001 Tim Janik <timj@gtk.org>
* gboxed.[hc]: remove left-over usages of an anonymous GBoxed typedef.
* gobjectnotifyqueue.c: moved property notify queue implementation
bits into this function.
* gparam.[hc]: added g_param_spec_pool_belongings(), completed
g_param_spec_pool_list(). added GParameter for _setv() functions.
* gobject.[hc]: use gobjectnotifyqueue.h implementation now.
got rid of properties_changed signal.
new functions g_object_newv(), g_object_class_list_properties().
removed "properties_changed" signal.
* gtype.[hc]: added g_type_depth() to figure number of parent
types + 1 for a type.
* gsignal.h: add g_signal_connect() (as per owen's request) and
g_signal_connect_swapped().
Tue May 22 02:46:13 2001 Tim Janik <timj@gtk.org>
* gobject.c (g_value_set_object): make g_value_set_object()
take a gpointer v_object so people don't need to G_OBJECT()
cast NULL pointers (C code convenience).
Thu May 3 06:10:23 2001 Owen Taylor <otaylor@redhat.com>
* gobject.c (g_object_set_[q]data_full): Make types of ternary
operator correspond. (Fixes compilation errors with Sun CC,
#52230)
2001-04-19 Havoc Pennington <hp@redhat.com>
* gobject.c (g_object_get_valist): We were returning junk memory
here, because we didn't copy the value (G_VALUE_NOCOPY_CONTENTS
passed to G_VALUE_LCOPY) and then we freed the GValue immediately
after. Removed G_VALUE_NOCOPY_CONTENTS from here; need a
G_VALUE_STEAL_CONTENTS or the like if we want this optimization.
Wed Mar 14 18:46:54 2001 Tim Janik <timj@gtk.org>
* gscanner.[hc]: removed archaic gpointer derived_data; relict and
added a GData member instead.
* glist.[hc]: added g_list_remove_all().
* gslist.[hc]: added g_slist_remove_all().
Sat Mar 17 23:18:36 2001 Tim Janik <timj@gtk.org>
* gobject.c (g_object_get_property): minor bug-fix.
* gbsearcharray.[hc]: provide a macro for static initialization and
functions g_bsearch_array_new() and g_bsearch_array_destroy() for
dynamic allocations.
* gboxed.c: introduce G_TYPE_GSTRING, boxed type for GString.
* gclosure.[hc]: naming corrections.
Fri Mar 9 16:42:08 2001 Tim Janik <timj@gtk.org>
* gvaluetypes.[hc]: moved g_strdup_value_contents() into this file as
a public function (was static in gobject.c before). it's a bit odd
to have that function here, especially since it requires extra includes,
but then it doesn't very well fit somewhere else either.
* gparamspecs.c: added default/max/min checks to param spec creation
functions.
Fri Mar 9 18:01:43 2001 Tim Janik <timj@gtk.org>
* gscanner.[hc]: made config arg to g_scanner_new() const.
Fri Mar 9 16:42:08 2001 Tim Janik <timj@gtk.org>
* gvaluetypes.[hc]: moved g_strdup_value_contents() into this file as
a public function (was static in gobject.c before). it's a bit odd
to have that function here, especially since it requires extra includes,
but then it doesn't very well fit somewhere else either.
* gparamspecs.c: added default/max/min checks to param spec creation
functions.
Thu Mar 8 16:23:34 2001 Tim Janik <timj@gtk.org>
* ghook.[hc]: destruction cleanup. there's one
->finalize_hook member in the hooklist now that gets
called when a hook should be destroyed, that's it.
that function is guarranteed to be called only when
all ref_counts to the hook vanished, thus also when
the hook is not in call.
Thu Mar 8 16:35:48 2001 Tim Janik <timj@gtk.org>
* gparamspecs.[hc]: s/g_param_spec_string_c/g_param_spec_stringc/.
* gsignal.[hc]: fixed accumulator invocation, implemented emission
hooks. and no, neither of these callbacks are called via a closure,
language bindings can wrap the accumulator and emission hook
interface, they already get parameters marshalled into a GValue array.
(g_signal_connect): removed this function as its C specific, doesn't
cover the swapped argument, is too close to its broken original
gtk_signal_connect() and creates demand for _swapped, _after and
_swapped_after variants <brrr>.
(g_signal_connectc): convenience macro to connect a C handler
func with data, like the old g_signal_connect() plus swapped
argument.
* gtype.h:
* gboxed.c: added G_TYPE_VALUE boxed type.
Wed Mar 7 09:36:33 2001 Tim Janik <timj@gtk.org>
* gboxed.[hc]: changed prototype of g_boxed_type_register_static()
to contain an optional init function and a hint at whether the
boxed structure uses ref counting internally.
added g_value_set_boxed_take_ownership().
made G_TYPE_BOXED an abstract value type.
* genums.[hc]: made G_TYPE_ENUM and G_TYPE_FLAGS abstract value
types.
* glib-genmarshal.c: argument type changes, preparation for third-party
arg specification.
* gobject.[hc]: cleaned up get/set property code.
added g_strdup_value_contents() to improve warnings.
* gparam.[hc]: added g_param_value_convert(), taking over responsibility
of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so
validation alterations may be valid a part of the property setting
process.
* gparamspecs.[hc]: made value comparisons stable (for sort applications).
added GParamSpecValueArray, a param spec for value arrays and
GParamSpecClosure. nuked the value exchange functions and
GParamSpecCCallback.
* gtype.[hc]: catch unintialized usages of the type system with
g_return_val_if_uninitialized(). introduced G_TYPE_FLAG_VALUE_ABSTRACT
to flag types that introduce a value table, but can't be used for
g_value_init(). cleaned up reserved type ids.
* gvalue.[hc]: code cleanups and saner checking.
nuked the value exchange API. implemented value transformations, we
can't really "convert" values, rather transforms are an anylogy to
C casts, real conversions need a param spec for validation, which is
why g_param_value_convert() does real conversions now.
* gvaluearray.[hc]: new files that implement a GValueArray, a struct
that can hold inhomogeneous arrays of value (to that extend that it
also allowes undefined values, i.e. G_VALUE_TYPE(value)==0).
this is exposed to the type system as a boxed type.
* gvaluetransform.c: new file implementing most of the former value
exchange functions as single-sided transformations.
* gvaluetypes.[hc]: nuked G_TYPE_CCALLBACK, added
g_value_set_string_take_ownership().
* *.h: s/G_IS_VALUE_/G_VALUE_HOLDS_/.
* *.[hc]: many fixes and cleanups.
* many warning improvements.
Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org>
* gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS
into G_VALUE_LCOPY(), this needs proper documenting.
* gparam.c: fixed G_PARAM_USER_MASK.
* gtype.c (type_data_make_W):
(type_data_last_unref_Wm): fixed invalid memory freeing.
* gobject.c (g_object_last_unref): destroy signal handlers associated
with object, right before finalization.
* gsignal.c (g_signal_parse_name): catch destroyed nodes or signals
that don't actually support details.
* gobject.[hc]: got rid of property trailers. nuked GObject
properties "data" and the "signal" variants.
(g_object_connect): new convenience function to do multiple
signal connections at once.
(g_object_disconnect): likewise, for disconnections.
* gparam.[hc] (g_param_spec_pool_lookup): took out trailer support.
* gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer()
as private (the latter got renamed from g_value_get_as_pointer()).
Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org>
* glib-object.h: add gvaluearray.h.
* gstring.[hc]: fixup naming of g_string_sprint*.
* gtypes.h: fixed GCompareDataFunc naming.
Wed Mar 7 09:33:27 2001 Tim Janik <timj@gtk.org>
* gobject/Makefile.am: shuffled rules to avoid excessive
rebuilds.
* gobject/gobject-sections.txt: updates.
* gobject/tmpl/*: bunch of updates, added another patch
from Eric Lemings <eric.b.lemings@lmco.com>.
Sat Feb 17 04:55:35 2001 Tim Janik <timj@gtk.org>
* gtype.[hc]: changed collect_format, collect_value() and lcopy_format,
lcopy_value() in the GTypeValueTable. the collect functions are now
called only once per value, collect_format/lcopy_format are strings
that enlist all necessary GTypeCValues to be varargs-collected.
* gvalue.h: ranamed STATIC_TAG to G_VALUE_NOCOPY_CONTENTS to indicate that
a value shouldn't copy its contents.
* gvaluecollector.h: changed G_VALUE_COLLECT() and G_VALUE_LCOPY()
macros to carry an additional argument (flags) that can be used
to pass G_VALUE_NOCOPY_CONTENTS along to the collection functions.
* *.c: adapted collect_value() and lcopy_value() functions to the new
prototypes, support G_VALUE_NOCOPY_CONTENTS where apropriate.
* gsignal.[hc]: introduced a G_SIGNAL_TYPE_STATIC_SCOPE flag that can
be passed along (ORed) with the parameter types, indicating that the
emission arguments are to be considered static for the scope of the
emission. should be used with care and only if the caller knows that
a parameter cannot be destroyed/freed from signal handlers connected
to an emission.
Sun Feb 4 07:38:32 2001 Tim Janik <timj@gtk.org>
* docs/debugging.txt: s/glib_trap_/g_trap_/. add comments on
g_trap_instance_signals, g_trace_instance_signals and
GRUNTIME_DEBUG.
* gmem.c: s/glib_trap_/g_trap_/.
Sun Feb 4 07:30:53 2001 Tim Janik <timj@gtk.org>
* gtype.[hc]: changed g_type_init() to take debugging flags
initially, a combination of G_TYPE_DEBUG_OBJECTS and
G_TYPE_DEBUG_SIGNALS. using the G_TYPE_ prefix is a bit odd
here, but basically g_type_int() serves as initialization
fucntion for all of GType, GObject, GSignal, so what the heck.
* gobject.c: special case debugging code properly.
changed glib_trap_object_ref to g_trap_object_ref.
* gsignal.c: add signal emission debugging abilities, along with
a new trap object g_trap_instance_signals.
