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()).
* gboxed.[hc]: Add g_value_take_boxed() (synonym to the
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)
Tue Sep 2 19:37:21 2003 Tim Janik <timj@gtk.org>
* gtype.[hc]: added support for a "default vtable" per interface,
that interface vtables are initialized from.
the default vtable is initialized and finalized through class_init,
class_finalize and class_data from the interfaces GTypeInfo struct.
(type_data_last_unref_Wm): unload child plugin before unreffing
parent type.
testifaceinit.c: minor fixups. fixed up base_init() assertions, since
with a default vtable, base_init() may be called multiple times.
added default initializer to iface1.
Mon Aug 25 14:16:48 2003 Owen Taylor <otaylor@redhat.com>
* gtypemodule.c (g_type_module_register_type): Clarify
docs on the return. Fix a memory leak if a type with a
value table is reloaded.

the original string. (#78197)
Tue Jan 29 11:18:44 2002 Owen Taylor <otaylor@redhat.com>
* 1.3.13
* NEWS: Updated.
* configure.in: Micro == 13, binary age, interface age 0.
[ binary breakage was return type of g_signal_connect_object(),
probably could have used binary age == 0, but a little safer not to.]
* configure.in: Remove configure warning.
Wed Nov 28 18:34:22 2001 Owen Taylor <otaylor@redhat.com>
* glib/gmain.[ch]: Rename (private) GSource.id and
id parameter to g_main_context_find_source_by_id()
to avoid problems with Objective C where 'id' is
a keyword. (#65616)
Sun Nov 25 22:33:32 2001 Tim Janik <timj@gtk.org>
* gtype.h: removed enum GTypeFundamentals. use macros
to provide the constant fundamental type IDs, so they
all return numbers of type GType, and not int.
sizeof(GTypeFundamentals) < sizeof(GType) problem reported
and fix sugegsted by Havoc.
Thu Nov 22 00:26:26 2001 Tim Janik <timj@gtk.org>
* gtype.[hc]: provide G_TYPE_FUNDAMENTAL_SHIFT and
g_type_fundamental_next() to return next usable fundamental
type. use TypeNode pointers as type IDs.
Wed Nov 21 17:23:33 2001 Tim Janik <timj@gtk.org>
* gparamspecs.[hc]: put newly created param spec types into a
global array.
* gboxed.[hc]: moved boxed types with _get_type() function here,
for: G_TYPE_CLOSURE, G_TYPE_VALUE, G_TYPE_VALUE_ARRAY,
G_TYPE_GSTRING.
* gtype.h: removed fundamental branch APIs and derived enum
values.
Tue Nov 13 21:31:58 2001 Tim Janik <timj@gtk.org>
* gobject/tmp/param_value_types.sgml: list parameter and
value types.

functions.
* gobject/*: section cleanups.
Fri Oct 12 18:24:02 2001 Tim Janik <timj@gtk.org>
* glib/gpattern.[hc]: make struct _GPatternSpec and GMatchType
private.
(g_pattern_equal): new function to return equality of two patterns
(required because GPatternSpec is private now).
(g_pattern_spec_new): fix bug wrg wildcard counting which produced
incorrect pattern specs (discovered by Matthias Clasen).
optimized code so we just keep one compiled pattern string now.
correctly canonicalize patterns. reduce string walks, optimize
decision about MATCH_ALL vs. MATCH_ALL_TAIL.
(g_pattern_match_string): call just g_pattern_match() with NULL
reversed string.
(g_pattern_match): allow NULL reversed strings now, reverse_dup
strings on demand.
* tests/patterntest.c (test_compilation): added an extended testcase
for pattern matching from Matthias Clasen <matthiasc@poet.de>.
Sat Oct 13 06:58:23 2001 Tim Janik <timj@gtk.org>

g_param_get_name() accessors.
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.
Mon Sep 10 17:13:36 2001 Tim Janik <timj@gtk.org>
* glib/gmessages.h: got rid of g_set_error_handler(),
g_set_warning_handler(), g_set_message_handler().
Wed Sep 5 05:24:07 2001 Tim Janik <timj@gtk.org>
* gobject/tmpl/gboxed.sgml: documented some functions.
* gobject/tmpl/objects.sgml: some fixups.
Mon Sep 10 19:27:47 2001 Tim Janik <timj@gtk.org>
* gtype.[hc]:
g_type_add_interface*(): implement the ability to add an interface to
a type whose parents already conform to this interface.
such "overriding" interfaces, when initialized, are not just initialized
with 0, but with a copy of the interface they override.
g_type_interface_peek_parent(): new function, return the interface
that this interface "overrides", if any.
* testgruntime.c: test new interface stuff.
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().
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 22:49:40 2001 Owen Taylor <otaylor@redhat.com>
* gtype.[ch] gobject-query.c testgruntime.c: Remove
debug flag argument to g_type_init() and add
g_type_init_with_debug_flags().
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 Apr 3 13:46:22 2001 Tim Janik <timj@gtk.org>
* glist.[hc]: added g_list_nth_prev() which walks ->prev instead
of ->next.
* gpattern.[hc]: added shell-style pattern matching code from beast,
derived from the gtk_pattern_*() code, but with a couple of bug fixes
and a number of optimizations.
Tue Apr 3 14:06:00 2001 Tim Janik <timj@gtk.org>
* gparam.[hc]: added g_param_spec_pool_list() to list pspecs per
owner_type. the pspecs are not referenced, so the caller is
supposed to have some idea about owner_type not randomly
nuking his pspec's. if this is going to provide problems in
the future, we can either auto-ref the pspecs, or add a
_foreach variant, though the latter would have to invoke
the callback while pspec's mutex is acquired, so i just
went for the _list variant for now.
* gclosure.h (G_CALLBACK): made GCallback a void (*) (void) fucntion.
Sat Mar 31 23:55:58 2001 Tim Janik <timj@gtk.org>
* gtype.h:
* gparamspecs.[hc]: applied patch from owen to implement
GParamSpecUnichar.
Fri Mar 30 07:34:02 2001 Tim Janik <timj@gtk.org>
* gtype.c (type_iface_retrive_holder_info_Wm):
* gtypeplugin.c (g_type_plugin_complete_interface_info):
* gtypemodule.c (g_type_module_complete_interface_info):
change order of instance_type and interface_type so they match
the g_type_add_interface_*() API.
* gsignal.c (g_signal_emit_valist): always assign C return value
location, people depending on unaltered return values after emissions
that had no handlers to run need to use g_signal_emitv().
* gtype.[hc] (g_type_query): new function to allow querying of
class and object size (semantics like g_signal_query()).
currently the implementation is better held conservative so as to
only support types that are classed and static.
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.
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 15:02:17 2001 Owen Taylor <otaylor@redhat.com>
* gobject/Makefile.am: Revert Tim's last commit to
get rid of 7+ unnecessary / broken changes. Add
back the useful part. Also fix problem with grep,
add dependency on template files.
* gobject/gobject-sections.txt: Remove double
value_types names which was screwing up builds.
* glib/Makefile.am: Propagate changes from
gobject/Makefile.am
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>.
Mon Feb 19 07:32:38 2001 Tim Janik <timj@gtk.org>
* glib-config-2.0.in (lib_glib): my name is glib-config-2.0!
don't exit with errorcode!=0 for --help or -h.
* Makefile.am:
* configure.in: build glib-config-2.0.
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.
Fri Feb 16 06:52:20 2001 Tim Janik <timj@gtk.org>
* gobject/tmpl/types.sgml: incorporated huge docu patch from Eric
Lemings <eric.b.lemings@lmco.com> with a bunch of editing on my part.
Fri Feb 16 07:10:44 2001 Tim Janik <timj@gtk.org>
* gclosure.c:
(g_closure_ref):
(g_closure_sink): make closure sinking explicit.
* gsignal.c:
(g_signal_connect_data):
(g_signal_connect_closure):
(g_signal_connect_closure_by_id):
(g_signal_newv): perform explicit closure sinking.
Thu Feb 8 00:31:45 2001 Tim Janik <timj@gtk.org>
* gtype.h: added G_TYPE_DEBUG_NONE for/from Eric Lemings ;)
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.
Wed Jan 31 07:14:22 2001 Tim Janik <timj@gtk.org>
* gobject/Makefile.am: adapt to work with new CVS gtk-doc, leaving the old
rules in place caused bogus recursions. main changes:
- add to conditionalized section:
all-local:
$(MAKE) scan
$(MAKE) templates
$(MAKE) sgml
$(MAKE) html.stamp
html.stamp: sgml.stamp $(EXTRA_SGML_FILES)
$(MAKE) html
DOC_STAMPS= html.stamp sgml.stamp
- change:
maintainer-clean-local: clean
- cd $(srcdir) && rm -rf sgml html $(DOC_MODULE)-decl-list.txt $(DOC_MODULE)-decl.txt
+ cd $(srcdir) && rm -rf sgml html $(DOC_MODULE)-decl-list.txt $(DOC_MODULE)-decl.txt $(DOC_STAMPS)
* glib/Makefile.am (maintainer-clean-local): dito.
Wed Jan 31 06:21:32 2001 Tim Janik <timj@gtk.org>
* gobject/tmpl/types.sgml: applied docu patch from Eric Lemings
<eric.b.lemings@lmco.com>, did some more editing.
Wed Jan 31 06:19:49 2001 Tim Janik <timj@gtk.org>
* gparam.h: gtk-doc sucks for not dealing with #define inside enums.
* gtype.[hc]: added G_TYPE_FLAG_RESERVED_ID_BIT, a bit in the type
number that's supposed to be left untouched (preserved mainly
for the signal code).
* *.c: added thread safety code, based on an old patch from sebastian.
the remaining thread safety issues are now datalists on pspecs (to be
solved im gdataset.c) and gvalue.c where locking concerns value exchange
functionality only, and that's soon to be revised.
Tue Jan 9 03:10:38 2001 Tim Janik <timj@gtk.org>
* gobject/tmpl/types.sgml: added some function documentations.
* gobject/gobject-sections.txt: buncha fixups.
Fri Dec 29 14:53:18 2000 Tim Janik <timj@gtk.org>
* configure.in: we can't grow _cv_ variables by using a backticked
expr that refers back to the variable (glib_cv_sizeof_system_thread for
G_THREAD_USE_PID_SURROGATE), that'd keep the variable growing every time
it's evaluated. quantum states, anyone?)
