1 2001-06-13 Havoc Pennington <hp@redhat.com>
3 * Makefile.am (progs_LDADD): link to ./libgobject-1.3.la
4 since an installed libgobject was somehow being found; think
5 it's a libtool bug, but this workaround should do for now.
7 2001-06-12 Havoc Pennington <hp@redhat.com>
9 * Makefile.am (glib-mkenums): don't put $(srcdir)/glib-mkenums in
10 bin_SCRIPTS, that breaks make install. Instead put 'glib-mkenums'
11 in bin_SCRIPTS and cp it into builddir
13 Thu May 31 17:56:47 2001 Owen Taylor <otaylor@redhat.com>
15 * gobject-query.c: Fix mispelling in help output.
16 (#53952, Skip Montanaro)
18 2001-05-28 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
20 * Makefile.am (EXTRA_DIST): Really distribute glib-mkenums, now
21 that bin_SCRIPTS doesn't seem to care about doing so anymore.
23 Mon May 28 06:51:24 2001 Tim Janik <timj@gtk.org>
25 * gsignal.c (signal_emit_unlocked_R): fixed bad faux-pass, forgot
26 to release signal lock when restarting emissions.
28 Sun May 27 04:52:28 2001 Tim Janik <timj@gtk.org>
30 * gsignal.[hc] (g_signal_stop_emission_by_name): added variant
31 to stop signal emissions through a detailed_signal string.
33 * gsignal.c (signal_emit_R) (g_signal_emit_valist): account for
34 the fact that g_value_* functions may cause signal emissons by
35 unlocking the global signal system lock around g_value_* functions.
36 (signal_emit_unlocked_R): renamed this from signal_emit_R() to reflect
37 that this functions acquires the lock on its own now.
39 2001-05-24 Hans Breuer <hans@breuer.org>
41 * makefile.msc.in : changed depndencies to build glib-genmarshal
42 first and statically linked with glib, which makes it independent
43 from the installed glib version. Added new object files to build.
45 * gobject.def : updated
47 Thu May 24 08:52:02 2001 Owen Taylor <otaylor@redhat.com>
49 * gobject.[ch] (g_value_set_object): gpointer, not
52 2001-05-22 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
54 * Makefile.am (bin_SCRIPTS): made 'make distcheck' happy.
56 * gobject.def: Removed g_param_spec_stringc.
58 Tue May 22 02:46:13 2001 Tim Janik <timj@gtk.org>
60 * gobject.c (g_value_set_object): make g_value_set_object()
61 take a gpointer v_object so people don't need to G_OBJECT()
62 cast NULL pointers (C code convenience).
64 Mon May 14 01:49:01 2001 Tim Janik <timj@gtk.org>
66 * gsignal.[hc] (g_signal_handler_is_connected): new function
67 to check whether a handler is still connected to an instance
70 Thu May 10 14:00:48 2001 Tim Janik <timj@gtk.org>
72 * gparamspecs.[hc]: removed g_param_spec_stringc() in lack of
73 evidence of public need.
75 * gsignal.h: added g_signal_disconnect_by_func(),
76 g_signal_block_by_func() and g_signal_unblock_by_func() convenience
77 macros as per owen's request.
79 * gtype.c (SIZEOF_FUNDAMENTAL_INFO): align sizeof (GTypeFundamentalInfo)
80 to size of longs and pointers.
82 2001-05-05 James Henstridge <james@daa.com.au>
84 * Makefile.am: glib-mkenums is not a compiled program, so shouldn't
85 be in the bin_PROGRAMS primary. Put it in bin_SCRIPTS instead, and
86 removed the glib_mkenums_SOURCES var.
88 Thu May 3 06:10:23 2001 Owen Taylor <otaylor@redhat.com>
90 * gobject.c (g_object_set_[q]data_full): Make types of ternary
91 operator correspond. (Fixes compilation errors with Sun CC,
94 Mon Apr 30 20:03:56 2001 Tim Janik <timj@gtk.org>
96 * glib-mkenums (usage): removed \v escaping, newer perl versions don't
97 support this, and it'S probably useless anyways.
99 Sat Apr 28 23:39:42 2001 Tim Janik <timj@gtk.org>
101 * gsignal.[hc]: made signal handler and emission hook ids gulongs.
102 (signal_handlers_foreach_matched_R): only invoke callback for handlers
103 that are not disconnected (id>0).
104 (signal_emit_R): prevent invocation of signal handlers during the
105 emission they were connected within.
107 * glib-mkenums: publically installed perl-script to parse C code
108 enums and generate descriptions thereof.
109 * glib-mkenums.1: assorted man page.
111 2001-04-19 Havoc Pennington <hp@redhat.com>
113 * gobject.c (g_object_get_valist): We were returning junk memory
114 here, because we didn't copy the value (G_VALUE_NOCOPY_CONTENTS
115 passed to G_VALUE_LCOPY) and then we freed the GValue immediately
116 after. Removed G_VALUE_NOCOPY_CONTENTS from here; need a
117 G_VALUE_STEAL_CONTENTS or the like if we want this optimization.
119 Wed Apr 18 09:46:56 2001 Owen Taylor <otaylor@redhat.com>
121 * gobject.c gsignal.c: Change C++ comments for FIXME's to
122 C comments. (Patch from Andres Salomon)
124 2001-04-14 Hans Breuer <hans@breuer.org>
126 * gobject.def : updated
128 Mon Apr 9 18:56:15 2001 Tim Janik <timj@gtk.org>
130 * gclosure.c (g_closure_invoke): only require marshal/meta_marshal if
131 we're valid (about to actually do marshalling).
133 Tue Apr 3 20:23:24 2001 Tim Janik <timj@gtk.org>
137 Tue Apr 3 14:06:00 2001 Tim Janik <timj@gtk.org>
139 * gparam.[hc]: added g_param_spec_pool_list() to list pspecs per
140 owner_type. the pspecs are not referenced, so the caller is
141 supposed to have some idea about owner_type not randomly
142 nuking his pspec's. if this is going to provide problems in
143 the future, we can either auto-ref the pspecs, or add a
144 _foreach variant, though the latter would have to invoke
145 the callback while pspec's mutex is acquired, so i just
146 went for the _list variant for now.
148 * gclosure.h (G_CALLBACK): made GCallback a void (*) (void) fucntion.
150 Sat Mar 31 23:55:58 2001 Tim Janik <timj@gtk.org>
153 * gparamspecs.[hc]: applied patch from owen to implement
156 Fri Mar 30 07:34:02 2001 Tim Janik <timj@gtk.org>
158 * gtype.c (type_iface_retrive_holder_info_Wm):
159 * gtypeplugin.c (g_type_plugin_complete_interface_info):
160 * gtypemodule.c (g_type_module_complete_interface_info):
161 change order of instance_type and interface_type so they match
162 the g_type_add_interface_*() API.
164 * gsignal.c (g_signal_emit_valist): always assign C return value
165 location, people depending on unaltered return values after emissions
166 that had no handlers to run need to use g_signal_emitv().
168 * gtype.[hc] (g_type_query): new function to allow querying of
169 class and object size (semantics like g_signal_query()).
170 currently the implementation is better held conservative so as to
171 only support types that are classed and static.
173 2001-03-29 Tor Lillqvist <tml@iki.fi>
175 * gobject.def: Updates.
177 Wed Mar 28 17:04:06 2001 Tim Janik <timj@gtk.org>
179 * gobject.c (object_queue_property): only queue readable properties
180 for notification changes.
182 Thu Mar 22 13:36:50 2001 Tim Janik <timj@gtk.org>
184 * gsignal.c (g_signal_newv): catch G_SIGNAL_RUN_FIRST with a return value.
186 2001-03-21 Martin Baulig <baulig@suse.de>
188 * gboxed.[ch] (g_value_dup_boxed): This takes a `const GValue *'
191 2001-03-18 Tor Lillqvist <tml@iki.fi>
193 * gobject.def: Correct some renamed functions.
195 Sat Mar 17 23:18:36 2001 Tim Janik <timj@gtk.org>
197 * gobject.c (g_object_get_property): minor bug-fix.
199 * gbsearcharray.[hc]: provide a macro for static initialization and
200 functions g_bsearch_array_new() and g_bsearch_array_destroy() for
203 * gboxed.c: introduce G_TYPE_GSTRING, boxed type for GString.
205 * gclosure.[hc]: naming corrections.
207 Fri Mar 9 16:42:08 2001 Tim Janik <timj@gtk.org>
209 * gvaluetypes.[hc]: moved g_strdup_value_contents() into this file as
210 a public function (was static in gobject.c before). it's a bit odd
211 to have that function here, especially since it requires extra includes,
212 but then it doesn't very well fit somewhere else either.
214 * gparamspecs.c: added default/max/min checks to param spec creation
217 2001-03-10 Tor Lillqvist <tml@iki.fi>
219 * gobject.def: Add a couple of missing entries.
221 * Makefile.am (libgobject_1_3_la_LIBADD): Use only on Win32.
223 Fri Mar 9 14:57:17 2001 Tim Janik <timj@gtk.org>
225 * testgruntime.c: test program. covers run first/last/cleanup signal
226 handlers, return value accumulator, signal string returns, and
227 interface types in signal arguments.
229 * gtype.c (g_type_value_table_peek): for interface types without
230 value table, try looking up a value table from an instantiatable
231 prerequisite type (this is safe as an interface may only have
232 one instantiatable prerequisiste).
233 (type_check_is_value_type_U): same here.
235 * gsignal.c (g_signal_newv): assert that return types never have
236 G_SIGNAL_TYPE_STATIC_SCOPE set.
237 (g_signal_newc): only create class closure if the class_offset is not
240 Fri Mar 9 10:14:00 2001 Tim Janik <timj@gtk.org>
242 * gparamspecs.c (g_param_spec_object): use g_type_is_a() to check
243 for object_type being a G_TYPE_OBJECT, not G_TYPE_IS_OBJECT(), since
244 that wouldn't allow interface types.
246 * gtype.c (g_type_interface_add_prerequisite): arg, fixed small cnp bug
247 with bad implications and an off-by-one error.
249 Thu Mar 8 16:34:22 2001 Owen Taylor <otaylor@redhat.com>
251 * gvaluetransform.c: Include <string.h> for memcpy.
253 * gvaluetransform.c (DEFINE_SPRINTF): Remove unnecessary
254 and ANSI-illegal ## token pasting.
256 Thu Mar 8 18:11:52 2001 Tim Janik <timj@gtk.org>
258 * gsignal.c: eek, fixed old hook detail storage code.
260 Thu Mar 8 16:35:48 2001 Tim Janik <timj@gtk.org>
262 * gparamspecs.[hc]: s/g_param_spec_string_c/g_param_spec_stringc/.
264 * gsignal.[hc]: fixed accumulator invocation, implemented emission
265 hooks. and no, neither of these callbacks are called via a closure,
266 language bindings can wrap the accumulator and emission hook
267 interface, they already get parameters marshalled into a GValue array.
268 (g_signal_connect): removed this function as its C specific, doesn't
269 cover the swapped argument, is too close to its broken original
270 gtk_signal_connect() and creates demand for _swapped, _after and
271 _swapped_after variants <brrr>.
272 (g_signal_connectc): convenience macro to connect a C handler
273 func with data, like the old g_signal_connect() plus swapped
277 * gboxed.c: added G_TYPE_VALUE boxed type.
279 Wed Mar 7 19:02:51 2001 Tim Janik <timj@gtk.org>
281 * gtype.c (type_node_add_iface_entry_W): catch when adding an interface
282 to an ancestor of a child that already conforms to this interface.
283 currently we spew a warning here, should we be silent?
284 (g_type_interface_add_prerequisite): new function to add a prerequisite
285 type to an interface, that must succeed an instance is_a prerequisite
286 type check before the interface can be added to an instance. the
287 prerequisite types are also suuported in is_a checks of the interface.
288 (g_type_instance_is_a):
289 (g_type_check_instance_cast):
290 (g_type_check_instance): cleanups and optimizations.
292 (g_type_check_class_cast): same, also prevented these from accepting
293 interface types, as class structures don't nest interfaces.
295 2001-03-07 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
297 * Makefile.am: Avoid rebuilding everything everytime.
299 Wed Mar 7 09:36:33 2001 Tim Janik <timj@gtk.org>
301 * gboxed.[hc]: changed prototype of g_boxed_type_register_static()
302 to contain an optional init function and a hint at whether the
303 boxed structure uses ref counting internally.
304 added g_value_set_boxed_take_ownership().
305 made G_TYPE_BOXED an abstract value type.
307 * genums.[hc]: made G_TYPE_ENUM and G_TYPE_FLAGS abstract value
310 * glib-genmarshal.c: argument type changes, preparation for third-party
313 * gobject.[hc]: cleaned up get/set property code.
314 added g_strdup_value_contents() to improve warnings.
316 * gparam.[hc]: added g_param_value_convert(), taking over responsibility
317 of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so
318 validation alterations may be valid a part of the property setting
321 * gparamspecs.[hc]: made value comparisons stable (for sort applications).
322 added GParamSpecValueArray, a param spec for value arrays and
323 GParamSpecClosure. nuked the value exchange functions and
326 * gtype.[hc]: catch unintialized usages of the type system with
327 g_return_val_if_uninitialized(). introduced G_TYPE_FLAG_VALUE_ABSTRACT
328 to flag types that introduce a value table, but can't be used for
329 g_value_init(). cleaned up reserved type ids.
331 * gvalue.[hc]: code cleanups and saner checking.
332 nuked the value exchange API. implemented value transformations, we
333 can't really "convert" values, rather transforms are an anylogy to
334 C casts, real conversions need a param spec for validation, which is
335 why g_param_value_convert() does real conversions now.
337 * gvaluearray.[hc]: new files that implement a GValueArray, a struct
338 that can hold inhomogeneous arrays of value (to that extend that it
339 also allowes undefined values, i.e. G_VALUE_TYPE(value)==0).
340 this is exposed to the type system as a boxed type.
342 * gvaluetransform.c: new file implementing most of the former value
343 exchange functions as single-sided transformations.
345 * gvaluetypes.[hc]: nuked G_TYPE_CCALLBACK, added
346 g_value_set_string_take_ownership().
348 * *.h: s/G_IS_VALUE_/G_VALUE_HOLDS_/.
350 * *.[hc]: many fixes and cleanups.
352 * many warning improvements.
354 Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org>
356 * gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS
357 into G_VALUE_LCOPY(), this needs proper documenting.
359 * gparam.c: fixed G_PARAM_USER_MASK.
361 * gtype.c (type_data_make_W):
362 (type_data_last_unref_Wm): fixed invalid memory freeing.
364 * gobject.c (g_object_last_unref): destroy signal handlers associated
365 with object, right before finalization.
367 * gsignal.c (g_signal_parse_name): catch destroyed nodes or signals
368 that don't actually support details.
370 * gobject.[hc]: got rid of property trailers. nuked GObject
371 properties "data" and the "signal" variants.
372 (g_object_connect): new convenience function to do multiple
373 signal connections at once.
374 (g_object_disconnect): likewise, for disconnections.
376 * gparam.[hc] (g_param_spec_pool_lookup): took out trailer support.
378 * gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer()
379 as private (the latter got renamed from g_value_get_as_pointer()).
381 2001-02-21 Tor Lillqvist <tml@iki.fi>
383 * *.h: Use G_BEGIN_DECLS and G_END_DECLS.
385 * Makefile.am: Use libglib-1.3.la from top_builddir. Invoke
386 libtool with -no-undefined for Win32 and Cygwin.
388 Wed Feb 21 18:31:46 2001 Jonathan Blandford <jrb@redhat.com>
390 * gsignal.h (g_signal_connect): Add g_signal_connect define to
391 make porting from gtk_signal_connect easy.
393 * gsignal.c (g_signal_emit_valist): Use G_TYPE_FROM_INSTANCE
394 (instance) instead of node->itype when initting the value.
396 2001-02-17 Havoc Pennington <hp@pobox.com>
398 Applied patch from Soeren Sandmann:
400 * gvaluetypes.c (g_value_get_string): G_CONST_RETURN
402 * gtype.c (g_type_name): G_CONST_RETURN
404 * gsignal.c (g_signal_name): G_CONST_RETURN
406 * gobject-query.c (main): const fix
408 Sat Feb 17 07:58:46 2001 Tim Janik <timj@gtk.org>
410 * genums.h (G_TYPE_IS_FLAGS): patch from sven to fixup
411 G_ENUM_CLASS_TYPE() macro.
413 Sat Feb 17 04:55:35 2001 Tim Janik <timj@gtk.org>
415 * gtype.[hc]: changed collect_format, collect_value() and lcopy_format,
416 lcopy_value() in the GTypeValueTable. the collect functions are now
417 called only once per value, collect_format/lcopy_format are strings
418 that enlist all necessary GTypeCValues to be varargs-collected.
420 * gvalue.h: ranamed STATIC_TAG to G_VALUE_NOCOPY_CONTENTS to indicate that
421 a value shouldn't copy its contents.
423 * gvaluecollector.h: changed G_VALUE_COLLECT() and G_VALUE_LCOPY()
424 macros to carry an additional argument (flags) that can be used
425 to pass G_VALUE_NOCOPY_CONTENTS along to the collection functions.
427 * *.c: adapted collect_value() and lcopy_value() functions to the new
428 prototypes, support G_VALUE_NOCOPY_CONTENTS where apropriate.
430 * gsignal.[hc]: introduced a G_SIGNAL_TYPE_STATIC_SCOPE flag that can
431 be passed along (ORed) with the parameter types, indicating that the
432 emission arguments are to be considered static for the scope of the
433 emission. should be used with care and only if the caller knows that
434 a parameter cannot be destroyed/freed from signal handlers connected
437 Fri Feb 16 07:10:44 2001 Tim Janik <timj@gtk.org>
441 (g_closure_sink): make closure sinking explicit.
444 (g_signal_connect_data):
445 (g_signal_connect_closure):
446 (g_signal_connect_closure_by_id):
447 (g_signal_newv): perform explicit closure sinking.
449 Thu Feb 8 00:31:45 2001 Tim Janik <timj@gtk.org>
451 * gtype.h: added G_TYPE_DEBUG_NONE for/from Eric Lemings ;)
453 2001-02-04 Tor Lillqvist <tml@iki.fi>
455 * gobject.def: Remove glib_debug_objects.
457 Sun Feb 4 07:30:53 2001 Tim Janik <timj@gtk.org>
459 * gtype.[hc]: changed g_type_init() to take debugging flags
460 initially, a combination of G_TYPE_DEBUG_OBJECTS and
461 G_TYPE_DEBUG_SIGNALS. using the G_TYPE_ prefix is a bit odd
462 here, but basically g_type_int() serves as initialization
463 fucntion for all of GType, GObject, GSignal, so what the heck.
465 * gobject.c: special case debugging code properly.
466 changed glib_trap_object_ref to g_trap_object_ref.
468 * gsignal.c: add signal emission debugging abilities, along with
469 a new trap object g_trap_instance_signals.
471 2001-02-04 Tor Lillqvist <tml@iki.fi>
473 * Makefile.am (progs_LDADD): Change order of libs to libgobject
474 first, then libglib. Needed for cygwin, says jbdoll@kepri.re.kr.
476 Wed Jan 31 06:19:49 2001 Tim Janik <timj@gtk.org>
478 * gparam.h: gtk-doc sucks for not dealing with #define inside enums.
480 * gtype.[hc]: added G_TYPE_FLAG_RESERVED_ID_BIT, a bit in the type
481 number that's supposed to be left untouched (preserved mainly
482 for the signal code).
484 * *.c: added thread safety code, based on an old patch from sebastian.
485 the remaining thread safety issues are now datalists on pspecs (to be
486 solved im gdataset.c) and gvalue.c where locking concerns value exchange
487 functionality only, and that's soon to be revised.
489 2001-01-27 Tor Lillqvist <tml@iki.fi>
491 * makefile.msc.in: Don't try to compile gmarshal.c on its own.
493 2001-01-24 <alexl@redhat.com>
495 * gclosure.c (g_closure_unref):
496 Don't leak closure->notifiers.
498 2001-01-05 Havoc Pennington <hp@redhat.com>
500 * gparamspecs.c (g_param_spec_enum): set the value_type in the
501 param spec; closes bug 40210
502 (g_param_spec_flags): ditto for flags
504 2001-01-03 Alexander Larsson <alexl@redhat.com>
507 Move glib_debug_objects out of the G_ENABLE_DEBUG #ifdef.
509 Thu Dec 28 11:36:44 2000 Tim Janik <timj@gtk.org>
511 * gbsearcharray.c (upper_power2): disable G_BSEARCH_ALIGN_POWER2
512 fucntionality if DISABLE_MEM_POOLS is defined.
514 * gtype.c: honour DISABLE_MEM_POOLS.
516 * gsignal.c (g_signal_init): flag signal key bsearch array with
517 G_BSEARCH_ALIGN_POWER2 to avoid excessive growth time. honour
520 * gparam.h: added G_PARAM_READWRITE alias for (G_PARAM_READABLE |
523 2000-12-15 Tor Lillqvist <tml@iki.fi>
525 * gobject.def: Update.
527 2000-12-15 Havoc Pennington <hp@pobox.com>
529 * gobject.c (g_object_do_class_init): use g_signal_newc
531 * gsignal.c (g_signal_newc): convenience function for signals
533 (g_signal_new_valist): added
534 (g_signal_new): removed
536 Fri Dec 15 04:40:23 2000 Tim Janik <timj@gtk.org>
538 * gparam.[hc]: add an instance member value_type so the default
539 value of the pspec class can be overridden.
541 2000-12-14 Tor Lillqvist <tml@iki.fi>
543 * makefile.mingw.in: Update, include parts from Makefile.am to
544 build gmarshal.[ch]. Some day, we won't need these separate
545 makefiles for Win32 compilation. I hope.
547 * makefile.msc.in: Update. No use trying to build gmarshal.[ch]
548 here, it would require Unixish tools. MSVC users building from CVS
549 sources are out of luck.
551 * gobject.def: Update.
553 Wed Dec 13 09:31:26 2000 Tim Janik <timj@gtk.org>
555 * gparamspecs.[hc]: add G_TYPE_PARAM_BOXED implementation.
557 * gobject.[hc]: minor fixes.
559 Tue Dec 12 23:38:02 2000 Tim Janik <timj@gtk.org>
561 * Makefile.am: _never_ touch oldest-source-stamp.
563 * gobject.[hc]: construct property handling fixes/improvements.
564 fixed trailer handling in get/set property.
566 * gparam.[hc]: implement param spec pool, got rid of param spec
567 hashtable. the most prominent change is that e deal with type
570 2000-12-12 Elliot Lee <sopwith@redhat.com>
573 . You have to 'touch oldest-source-stamp' if you want to avoid having
574 the Makefile constantly rebuild itself.
575 . Fix marshaller generation rules to work with srcdir != builddir
576 (there were issues with trying to run "./glib-genmarshal", etc.)
578 Mon Dec 11 04:44:11 2000 Tim Janik <timj@gtk.org>
580 * gboxed.c: fixed dealing with collection/lcopy of NULL values.
582 * gclosure.h: removed insane ramblings, added G_CALLBACK() a casting
585 * Makefile.am: cleanups, marshaller generation rules.
587 * gmarshal.[hc]: new files with GRuntime standard marshallers.
589 * glib-genmarshal.c: fix log domain, support gruntime standard
590 marshallers, suport G_TYPE_PARAM, come with extern "C" and
593 * glib-genmarshal.1: reflect glib-genmarshal.c updates.
595 * gobject.[hc]: implement object constructor. rework parameter
596 changed notification queueing, we support queue freezes now and
597 don't dispatch from an idle handler anymore.
598 parameter->property rename hassle.
599 implemented ::properties_changed and ::notify::* signals for
600 property change notification (the later supports property names
601 as details). added signal connection and named data properties.
602 (g_signal_connect_object): new function to setup while_alive
604 (g_object_class_install_property): sink properties now, since they
605 are initially floating.
606 (g_object_steal_data):
607 (g_object_set_data_full):
609 (g_object_get_data): set/get data by using g_datalist_*() functions
611 (g_object_queue_param_changed): nuked.
612 (g_object_freeze_notify): start queueing of property changes (freeze/
614 (g_object_notify): announce changes of a certain property directly.
615 (g_object_thaw_notify): process queue of property changes, therefore
616 emitting GObject::notify::detail with detail being the changed
618 (G_OBJECT_WARN_INVALID_PROPERTY_ID): saner macro variant of former
619 G_WARN_INVALID_PARAM_ID().
621 * gparam.[hc]: param specs are now initially floating and need to be
622 sunken with g_param_spec_sink(), support G_TYPE_PARAM values.
623 added G_PARAM_CONSTRUCT and G_PARAM_CONSTRUCT_ONLY parameter flags,
624 required by GObjectClass.constructor().
626 * gparamspecs.[hc]: added GParamSpecParam, GParamSpecPointer and
627 GParamSpecCCallback, param specs for G_TYPE_PARAM, G_TYPE_POINTER
628 and G_TYPE_CCALLBACK respectively.
630 * gsignal.[hc]: cleanups.
631 (signal_id_lookup): after walking the anchestry, try interfaces as well.
632 (g_signal_new): new function to create signals from varargs type list.
633 (g_signal_connect_closure): closure connection variant that works from
635 (g_signal_connect_data): c handler connection variant that works from
637 (g_signal_emit_valist): emit signal for an instance with paraneters
638 collected from a va_list.
639 (g_signal_emit): emit signal, taking parameters from varargs list.
640 (g_signal_emit_by_name): same as g_signal_emit, working from
642 (signal_emit_R): return whether return_value needs to be altered.
644 * gtype.[hc]: set log-domain to GRuntime, i'm slowly getting to all
645 the points that need to reflect the upcoming rename.
646 melt g_type_conforms_to() functionality into g_type_is_a(), as that
647 is what we really want (liskov substitution principle).
648 assorted changes to other files due to conforms_to->is_a.
650 * gvalue.[hc]: implemented g_value_set_instance() that sets a value
651 from an instantiatable type via the value_table's collect_value()
652 function (based on an idea from James Henstridge <james@daa.com.au>).
655 * gvaluetypes.[hc]: implement G_TYPE_CCALLBACK and G_TYPE_PARAM.
657 Wed Nov 29 13:30:05 2000 Tim Janik <timj@gtk.org>
659 * gsignal.c (handlers_find): fix elliots "logic fix" that dereferences
660 NULL nodes if C handlers are searched for specific signals.
662 2000-11-28 Elliot Lee <sopwith@redhat.com>
664 * gsignal.c: Fix warnings about possible use of uninitialized
665 variables, and fix logic that would leave 'node' unset in cases
666 that it might be used in.
668 * glib-genmarshal.c: Fix warning about printf format.
670 2000-11-28 Tor Lillqvist <tml@iki.fi>
672 * gboxed.c: Include <string.h> for memset ().
674 2000-11-22 Tor Lillqvist <tml@iki.fi>
676 * gobject.def: Update.
678 2000-11-20 Havoc Pennington <hp@redhat.com>
680 * gobject.c (g_object_get_data)
682 (g_object_set_data_full)
683 (g_object_steal_data): More convenient data-setting functions
685 Wed Nov 15 20:58:05 2000 Owen Taylor <otaylor@redhat.com>
687 * gtypemodule.c (g_type_module_use): If loading the
688 module fails, don't increment the use count.
690 Thu Nov 9 01:49:43 2000 Tim Janik <timj@gtk.org>
692 * gobject.h (G_WARN_INVALID_PARAM_ID): doh,
693 s/BSE_OBJECT_TYPE_NAME/G_OBJECT_TYPE_NAME/; reported by Maas-Maarten
694 Zeeman <maas@wanadoo.nl>.
696 Mon Nov 13 00:48:39 2000 Owen Taylor <otaylor@redhat.com>
698 * Makefile.am (EXTRA_DIST): Add glib-genmarshal.1
700 2000-11-11 Tor Lillqvist <tml@iki.fi>

708 Sun Nov 5 13:21:28 2000 Owen Taylor <otaylor@redhat.com>
710 * Makefile.am gtypemodule.[ch]: New basic implementation of
711 GTypePlugin interface as a GObject. Dynamically loaded modules can
712 register any number of types and interface on the module.
714 Sun Nov 5 10:25:40 2000 Owen Taylor <otaylor@redhat.com>
716 * gsignal.c (handlers_find): When appending handlers and
717 not matching on signal_id, use hlist->signal_id instead of
718 signal_id. Having the correct signal_id when unreffing
719 the handlers makes things work a lot better.
721 2000-11-05 Tor Lillqvist <tml@iki.fi>
723 * makefile.{mingw,msc}.in (gobject_OBJECTS): Add gtypeplugin.
725 * gobject.def: Update.
727 Sun Nov 5 05:22:55 2000 Tim Janik <timj@gtk.org>
730 fixed a bag full of subtle bugs of immensive screw-up potential in
731 handlers_find(), luckily no one found out about them yet ;)
732 fixed signal_handlers_foreach_matched_R() so it operates on an
733 initial handler list snapshot provided by handlers_find() to work
734 around general reentrancy problems and to avoid multiple callback()
735 invocations on the same handlers.
736 this code is now officially 80% bug free (10% remaining for interface
737 types, and 10% remaining for destroyed signals ;)
739 Sat Nov 4 02:01:33 2000 Tim Janik <timj@gtk.org>
741 * gsignal.c (_g_signals_destroy): valid signal nodes start out at 1.
743 * gtypeplugin.[hc]: new files holding a GTypePlugin interface
744 implementation that provides the API required by GType to deal with
745 dynamically loadable types.
747 * gtype.[hc]: displace any GTypePlugin business to gtypeplugin.h.
749 Fri Nov 3 07:35:00 2000 Tim Janik <timj@gtk.org>
751 * gsignal.[hc]: prefix internal functions with '_'. renamed
752 g_signal_connect_closure() to g_signal_connect_closure_by_id().
753 added g_signal_parse_name() to retrive signal_id and detail quark
754 from a signal name (internal).
756 Wed Nov 1 03:36:54 2000 Tim Janik <timj@gtk.org>
758 * gobject.c (g_object_base_class_finalize): destroy all signals that
759 the finalized obejct type introduced.
761 * gsignal.c (g_signals_destroy): don't require itype to have
764 * gobject.c (g_object_do_finalize): make sure all signal handlers
768 (g_signal_handler_find): only match on non-0 masks.
769 (g_signal_handlers_block_matched):
770 (g_signal_handlers_unblock_matched):
771 (g_signal_handlers_disconnect_matched): new functions to block/unblock
772 or disconnect handlers in groups.
774 2000-10-30 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
776 * gvalue.c (exchange_entries_equal), gparam.c (param_spec_equals):
777 made both functions return gboolean just for the little extra
778 standard conformance now that GEqualFunc is introduced.
780 Mon Oct 30 05:52:45 2000 Tim Janik <timj@gtk.org>
782 * gsignal.c (g_signal_list_ids): get rid of inline documentation owen
783 added, the doc system would ignore it anyways (for some reason not
786 Mon Oct 30 03:00:07 2000 Tim Janik <timj@gtk.org>
788 * gsignal.[hc] (g_signal_list_ids): renamed owen's g_type_signals(),
789 added required mutex locks.
791 Sun Oct 29 02:31:03 2000 Owen Taylor <otaylor@redhat.com>
793 * gsignal.c (g_type_signals): Fix problem where signals
794 with "_" in them appeared twice in the result array.
796 Sun Oct 29 01:58:44 2000 Owen Taylor <otaylor@redhat.com>
798 * gsignal.h: Add g_type_signals() - a function to list
799 all signals for a given type.
801 Sat Oct 28 00:28:09 2000 Tim Janik <timj@gtk.org>
803 * gclosure.c (g_closure_add_marshal_guards): fixed notifier position
804 for post_marshal guard which was off at 0.
806 Fri Oct 27 21:49:31 2000 Tim Janik <timj@gtk.org>
808 * gobject.[hc]: doh, fix argument order in for
809 g_cclosure_new_object_swap and g_cclosure_new_object.
811 2000-10-28 Tor Lillqvist <tml@iki.fi>
813 * makefile.{mingw,msc}.in: Make glib-genmarshal.exe.
815 * glib-genmarshal.c: Conditionalise include of unistd.h.
816 Include <io.h> on Win32.
818 * gobject.def: Add some missing entry points.
820 Fri Oct 27 16:33:41 2000 Tim Janik <timj@gtk.org>
822 * gsignal.[hc]: publically define GSignalInvocationHint structure
823 that gets passed in to closure invocations. added signal details.
824 renamed GSignalType to GSignalFlags to comply with conventions.
825 quite some cleanups and minor fixes. avoid uneccessary handler list
826 walks upon invokation of after handlers. relookup handler list for
827 restarted emissions. preliminary abort normal handler invokation if
828 after handler is encountered.
831 * gclosure.[hc]: moved invocation_hint to the end of the
832 g_closure_invoke() arguments as sugegsted by kenelson.
833 also made it a gpointer to be more generic. the invocation_hint
834 is a caller specific thing that can be used to pass additional
835 data in to closure invocations as documented with the caller
836 invoking the closure.
838 Fri Oct 27 05:35:14 2000 Tim Janik <timj@gtk.org>
840 * gobject.c (g_object_watch_closure): fixed realloc bug, reported
843 * gsignal.c (g_signal_newv): fixed deadlock scenarion where
844 g_signal_lookup() would be called with the signal lock being
845 held. reported by james henstridge.
847 * gclosure.c (g_closure_set_meta_marshal): fixed memcpy/overwrite bug
850 2000-10-26 Tor Lillqvist <tml@iki.fi>
852 * gbsearcharray.c (bsearch_array_insert): Fix gccisms (pointer
853 arithmetic on void pointer, label without statement following.
855 * gtype.c (type_node_fundamental_info): Don't apply unary minus to
856 result of sizeof operator, it can be unsigned. Cast first to
859 * gobject.def: Add new functions.
861 * makefile.{mingw,msc}.in: Add new objects.
863 2000-10-26 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
865 * Makefile.am: Remove empty SUBDIRS line _again_, as that _still_
866 prevents 'make dist' from working.
868 Wed Oct 25 19:11:03 2000 Owen Taylor <otaylor@redhat.com>
870 * gbsearcharray.h (g_bsearch_array_get_nth): Don't use implicit
871 casts from void * since this will get included from C++ too
874 Thu Oct 26 00:30:27 2000 Tim Janik <timj@gtk.org>
876 * gvaluetypes.[hc]: added g_value_set_static_string().
878 * gboxed.[hc]: const corrections. added g_value_set_static_boxed().
880 Wed Oct 25 20:27:02 2000 Tim Janik <timj@gtk.org>
882 * gtype.c (g_type_free_instance): for the moment, freeing object
883 structures will fill their memory portion with 0xAA. there's a
884 FIXME there, remove this line at a later point.
886 Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org>
889 * glib-genmarshal.c: added publically installed marshaller generator.
891 * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain
892 interface VTable from instances.
894 Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org>
896 * gobject.[hc]: new functions for closure maintenance:
897 (g_object_watch_closure): maintain validity of the object and
898 the closure for objects that are used as data part of a closure.
899 (g_cclosure_new_object): convenience function to create C closures
900 that have an object as data argument.
901 (g_closure_new_object): convenience function to create closures
902 that have an object as data argument.
904 * gclosure.[hc]: implementation of GClosure mechanism.
905 a closure is basically an encapsulation of a callback function
906 and its environment. ideally, most places supporting callback
907 functions will simply take a GClosure* pointer and thus unify
908 callback environments wrg destroy notification etc.
909 GClosure provides destroy notifiers for arbitrary data pointers,
910 reference counting, invalidation notification (it can be invalidated
911 which is merely a deactivate state) and a marshallinbg abstraction.
912 GCClosure is also provided in these files, they present a specialized
913 GClosure implementation for C language callbacks.
915 * genum.c: macro cleanups.
917 * gboxed.[hc]: new files, for boxed type abstraction.
918 (g_boxed_copy): copy a boxed structure
919 (g_boxed_free): free a boxed structure
921 (g_value_get_boxed): standard GValue functions for boxed types
922 (g_boxed_type_register_static): convenience function for easy
923 introduction of new G_TYPE_BOXED derivatives.
925 * gparam.[hc]: introduced g_param_type_register_static(), a short hand
926 for creation of new GParamSpec derived types.
928 * gtype.[hc]: many fixes, introduced ability to flag individual
929 type nodes as ABSTRACT upon registration, added value_peek_pointer()
930 to the value table to peek at GValue contents as a pointer for types
931 that support this. fixed up GValue checks.
933 * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer()
934 to peek at the value contents as pointer.
936 * *.[hc]: adaptions to type macro fixes and changes in the type
939 * many const corrections over the place.
941 Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org>
943 * gtype.c (g_type_conforms_to): this function basically behaves like
944 and is_a check, except that it _additionally_ features interfaces
945 for instantiatable types. enforce this in the second branch as well
946 (`type' conforms_to `type') even if `type' is not an interface type.
948 Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org>
950 * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb.
954 * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and
955 suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT
958 Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org>
960 * gbsearcharray.[hc]: long standing needed generic implementation
961 of a binary searchable, sorted and dynamically sized array.
963 2000-10-15 Raja R Harinath <harinath@cs.umn.edu>
965 * Makefile.am (BUILT_EXTRA_DIST): New variable.
966 (dist-hook): Handle $(BUILT_EXTRA_DIST).
967 (*): Remove traces of @STRIP_{BEGIN,END}@.
969 2000-09-29 Martin Baulig <baulig@suse.de>
971 Several minor ANSI C fixes.
974 * gtype.c (type_class_init):
975 `(gpointer) bnode->data->class.class_init_base'
976 in call to g_slist_prepend() and
977 'GBaseInitFunc class_init_base = (GBaseInitFunc) slist->data'.
979 * gobject.c: Put text following #endif into comments.
981 2000-09-25 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
983 * Makefile.am: Remove empty SUBDIRS line, as that prevents make
986 Sat Sep 9 20:04:13 2000 Owen Taylor <otaylor@redhat.com>
988 * gobject.c (g_object_last_unref): Move call to
989 g_type_free_instance() here from g_object_do_finalize,
990 since g_type_free_instance() can unload the object's
993 2000-07-27 Tor Lillqvist <tml@iki.fi>
995 * gobject.c: No, don't mark glib_debug_objects for export here,
996 it's handled specially in gtktypeutils.c.
998 * gobject.def: Export g_type_fundamental_last (the function).
1000 2000-07-26 Tor Lillqvist <tml@iki.fi>
1003 * gobject.c: Mark glib_debug_objects for export/import as it is
1006 Sun Jul 23 17:23:35 2000 Tim Janik <timj@gtk.org>
1008 * gtype.[hc]: make g_type_fundamental_last() a function, avoiding all
1009 that extern variable clutter and avoiding further problems with thread
1012 2000-07-19 Tor Lillqvist <tml@iki.fi>
1017 * gtype.c: Shut up Sun's picky compiler.
1019 2000-07-14 Tor Lillqvist <tml@iki.fi>
1021 * gobject.def: Add g_type_get_plugin.
1023 Thu Jul 13 02:07:54 2000 Tim Janik <timj@gtk.org>
1025 * gparam.c (g_param_value_defaults): default initialize the temporary
1026 default value, instead of nuking the caller's value contents.
1028 2000-07-11 Raja R Harinath <harinath@cs.umn.edu>
1030 * gtype.c (g_type_get_plugin): Don't return just 0 or 1.
1032 Tue Jul 11 02:48:13 2000 Tim Janik <timj@gtk.org>
1034 * gtype.[hc]: removed g_type_is_dynamic() and added g_type_get_plugin().
1036 2000-07-10 Tor Lillqvist <tml@iki.fi>
1038 * gobject-query.c: Include ../config.h for HAVE_UNISTD_H. Use it
1039 to guard inclusion of <unistd.h>.
1041 * gtype.h: Fix copy-paste errors in the ifdefs on how to declare a
1042 variable for export. Call the macro GOBJECT_VAR.
1044 * gtype.c: Declare _g_type_fundamental_last for export here, too.
1045 (type_node_any_new): Use only constant expressions for sizeof
1046 operator (for instance MSVC requires this).
1048 * makefile.mingw.in: Define GOBJECT_COMPILATION.
1050 Sun Jul 9 21:21:46 2000 Owen Taylor <otaylor@redhat.com>
1052 * genums.c: Move string.h include into the .c file
1053 instead of where it was in the .h file by mistake.
1055 Thu Jul 6 15:30:27 2000 Owen Taylor <otaylor@redhat.com>
1057 * Makefile.am (EXTRA_DIST): dist fixes.
1059 * gobject.c: Add a global variable glib_debug_objects
1060 (not in header file) to control object tracing.
1062 2000-07-01 Tor Lillqvist <tml@iki.fi>
1064 * gobject.def: Update added and renamed entry points.
1066 * makefile.mingw.in: Add gvaluetypes.o.
1068 Thu Jun 29 16:02:07 2000 Owen Taylor <otaylor@redhat.com>
1070 * gobject.c:include string.h for memset
1071 * genums.h: include string.h for strcpy
1072 * gvalue.c: include string.h for memset, memcpy.
1074 Sat Jun 24 23:03:04 2000 Tim Janik <timj@gtk.org>
1076 * gtype.[hc]: provide G_TYPE_CHAR, G_TYPE_UCHAR, G_TYPE_BOOLEAN,
1077 G_TYPE_INT, G_TYPE_UINT, G_TYPE_LONG, G_TYPE_ULONG, G_TYPE_FLOAT,
1078 G_TYPE_DOUBLE and G_TYPE_STRING fundamental types.
1079 added a GTypeValueTable* pointer to GTypeInfo structure for types
1080 to implement GValue handling functions.
1081 GTypeValueTable contains the following members:
1082 value_init(): initialize a GValue structure.
1083 value_free(): free GValue structure contents (optional).
1084 value_copy(): copy one GValue contents to another GValue structure of
1085 collect_type: varargs collection type for the first variable argument
1086 to be collected by collect_value().
1087 collect_value(): variable arguments collection function (optional).
1088 lcopy_type: varargs collection type for the first variable argument
1089 to be location copyied by lcopy_value().
1090 lcopy_value(): variable arguments location copy function (optional).
1091 g_type_value_table_peek(): new function to retrive the GTypeValueTable*
1092 for a type node. ValueTables get inherited from parent types, unless
1093 overridden through the GTypeInfo structure. internally, GTypeValueTable
1094 support means an added overhead of one pointer per static or used
1096 g_type_add_class_cache_func(): provide a cache_func/data pair to be
1097 called prior to a type nodes last_unref() function, this can be used
1098 to prevent premature class destruction. multiple installed cache_func()
1099 will be chained upon last_unref() untill one of them returns TRUE.
1100 the cache_func()s have to check the class id passed in to figure whether
1101 they actually want to cache the class of this type (since all classes
1102 are routed through the cache_func() chain).
1103 g_type_remove_class_cache_func(): remove a previously installed
1104 cache_func/data pair. the cache maintained by this function has to be
1105 clear when calling g_type_remove_class_cache_func() to avoid leaks.
1106 g_type_class_unref_uncached(): class unref function for cache_func()
1107 implementations, unreferences a class omitting the cache chain (and
1108 therefore unref->cache->unref->... loops).
1110 * gvaluetypes.[hc]: provide the value setters/getters for the primitive
1111 fundamental types boolean, char, uchar, int, uint, long, ulong, float,
1114 * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a
1115 GTypeValueTable is provided for this type.
1116 removed g_value_init_default(), g_value_validate(), g_value_defaults(),
1117 g_value_set_default() and g_values_cmp() as these are supplied by the
1119 moved g_values_exchange() into the "implementation details" section,
1120 since it just provides the underlying functionality for
1123 * gvaluecollector.h: renamed the varargs value container from
1124 GParamCValue to GTypeCValue as the value collection methods are
1125 supplied by the type system now.
1126 G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to
1127 G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a
1128 GParamSpec structure now.
1130 * genums.h: macros cleanups/fixes.
1132 * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type
1133 and assorted g_value_{s|g}et_{enum|flags}() implementations.
1136 provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods
1137 and g_value_{s|g}et_object().
1139 * gparam.[hc]: reduced class to value_set_default(),
1140 value_validate() and values_cmp(). also parameters now need to fill
1141 in a GType value_type; field to indicate the GValue type they
1142 are handling. provide g_param_value_set_default(),
1143 g_param_value_defaults(), g_param_value_validate() and
1144 g_param_values_cmp().
1146 * gparamspecs.[hc]: got rid of the g_value_* functions and
1147 the G_IS_VALUE_* macros. adapted param spec implementations
1148 according to the GParamSpecClass changes.
1150 Sat Jun 10 08:38:27 2000 Tim Janik <timj@gtk.org>
1152 * gtype.c (type_class_init): fetch the nth iface entry of the
1153 type node in the nth loop iteration, not alwys the first.
1154 bug discovered by Walt Pohl <cher@suitware.com>.
1155 (type_data_finalize_class_ifaces): same here, cut and paste
1158 Wed Jun 7 09:21:05 2000 Owen Taylor <otaylor@redhat.com>
1160 * Makefile.am (INCLUDES): Add top_builddir so glibconfig.h
1161 is found properly when build srcdir != builddir. (Patch from
1164 2000-05-13 Tor Lillqvist <tml@iki.fi>
1168 * gobject.rc.in: New files, for Win32 (mingw) build.
1170 * Makefile.am: Add to EXTRA_DIST. Add rules to produce the
1171 corresponding non-*.in files.
1173 * gtype.h: (Win32:) Mark _g_type_fundamental_last for
1174 export/import from DLL.
1176 Fri May 5 01:15:48 2000 Tim Janik <timj@gtk.org>
1178 * gtype.h: add reserved fundamental ids for gtk types (for transition
1179 time). added G_TYPE_FUNDAMENTAL_MAX for gtk.
1181 Mon Apr 17 20:45:50 2000 Tim Janik <timj@gtk.org>
1183 * glib-gobject.c (g_object_base_class_finalize): oops, don't unset
1184 n_params prior to destructing them.
1186 Tue Apr 11 04:28:10 2000 Tim Janik <timj@gtk.org>
1188 * fixed a couple of bugs in the initial parameter/object
1189 implementations, after getting beast running on GObject and GValue.
1191 Fri Apr 7 04:27:49 2000 Tim Janik <timj@gtk.org>
1193 * glib-gobject.[hc]: completed parameter set/get implementations,
1194 along with asyncronous parameter changed notification queue.
1196 Sun Apr 2 04:54:36 2000 Tim Janik <timj@gtk.org>
1198 * glib-gobject.[hc]: GObject implementation, that is facilities
1199 for setting/getting quarked data and reference counting.
1201 * glib-gparamspecs.[hc]: first actuall parameter implementations
1202 for GLib, so far we have: char, uchar, bool, int, uint, long,
1203 ulong, enum, flags, float, double, string and object. each of these
1204 GParamSpecs is a new instantiatable type in its own respect,
1205 so the .c file derives 13 new types from G_TYPE_PARAM and
1206 defines over 50 (*2) conversion facilities.
1208 * glib-gvaluecollector.h: generic varargs handling stubs for
1209 GParamSpecs, private header file (does get installed for
1210 inclusion into user code though).
1212 * glib-gvalue.[hc]: GValue functionality implementation.
1214 * glib-gparam.[hc]: basis GParamSpec implementation for
1215 the virtual base type G_TYPE_PARAM.
1217 * glib-genums.[hc]: enum/flags type implementation, based on
1220 * glib-gtype.[hc]: GLib Type System implementation, heavily
1221 based on BSE's dynamic type system.
