1 Wed Mar 7 19:02:51 2001 Tim Janik <timj@gtk.org>
3 * gtype.c (type_node_add_iface_entry_W): catch when adding an interface
4 to an ancestor of a child that already conforms to this interface.
5 currently we spew a warning here, should we be silent?
6 (g_type_interface_add_prerequisite): new function to add a prerequisite
7 type to an interface, that must succeed an instance is_a prerequisite
8 type check before the interface can be added to an instance. the
9 prerequisite types are also suuported in is_a checks of the interface.
10 (g_type_instance_is_a):
11 (g_type_check_instance_cast):
12 (g_type_check_instance): cleanups and optimizations.
14 (g_type_check_class_cast): same, also prevented these from accepting
15 interface types, as class structures don't nest interfaces.
17 2001-03-07 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
19 * Makefile.am: Avoid rebuilding everything everytime.
21 Wed Mar 7 09:36:33 2001 Tim Janik <timj@gtk.org>
23 * gboxed.[hc]: changed prototype of g_boxed_type_register_static()
24 to contain an optional init function and a hint at whether the
25 boxed structure uses ref counting internally.
26 added g_value_set_boxed_take_ownership().
27 made G_TYPE_BOXED an abstract value type.
29 * genums.[hc]: made G_TYPE_ENUM and G_TYPE_FLAGS abstract value
32 * glib-genmarshal.c: argument type changes, preparation for third-party
35 * gobject.[hc]: cleaned up get/set property code.
36 added g_strdup_value_contents() to improve warnings.
38 * gparam.[hc]: added g_param_value_convert(), taking over responsibility
39 of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so
40 validation alterations may be valid a part of the property setting
43 * gparamspecs.[hc]: made value comparisons stable (for sort applications).
44 added GParamSpecValueArray, a param spec for value arrays and
45 GParamSpecClosure. nuked the value exchange functions and
48 * gtype.[hc]: catch unintialized usages of the type system with
49 g_return_val_if_uninitialized(). introduced G_TYPE_FLAG_VALUE_ABSTRACT
50 to flag types that introduce a value table, but can't be used for
51 g_value_init(). cleaned up reserved type ids.
53 * gvalue.[hc]: code cleanups and saner checking.
54 nuked the value exchange API. implemented value transformations, we
55 can't really "convert" values, rather transforms are an anylogy to
56 C casts, real conversions need a param spec for validation, which is
57 why g_param_value_convert() does real conversions now.
59 * gvaluearray.[hc]: new files that implement a GValueArray, a struct
60 that can hold inhomogeneous arrays of value (to that extend that it
61 also allowes undefined values, i.e. G_VALUE_TYPE(value)==0).
62 this is exposed to the type system as a boxed type.
64 * gvaluetransform.c: new file implementing most of the former value
65 exchange functions as single-sided transformations.
67 * gvaluetypes.[hc]: nuked G_TYPE_CCALLBACK, added
68 g_value_set_string_take_ownership().
70 * *.h: s/G_IS_VALUE_/G_VALUE_HOLDS_/.
72 * *.[hc]: many fixes and cleanups.
74 * many warning improvements.
76 Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org>
78 * gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS
79 into G_VALUE_LCOPY(), this needs proper documenting.
81 * gparam.c: fixed G_PARAM_USER_MASK.
83 * gtype.c (type_data_make_W):
84 (type_data_last_unref_Wm): fixed invalid memory freeing.
86 * gobject.c (g_object_last_unref): destroy signal handlers associated
87 with object, right before finalization.
89 * gsignal.c (g_signal_parse_name): catch destroyed nodes or signals
90 that don't actually support details.
92 * gobject.[hc]: got rid of property trailers. nuked GObject
93 properties "data" and the "signal" variants.
94 (g_object_connect): new convenience function to do multiple
95 signal connections at once.
96 (g_object_disconnect): likewise, for disconnections.
98 * gparam.[hc] (g_param_spec_pool_lookup): took out trailer support.
100 * gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer()
101 as private (the latter got renamed from g_value_get_as_pointer()).
103 Wed Feb 21 18:31:46 2001 Jonathan Blandford <jrb@redhat.com>
105 * gsignal.h (g_signal_connect): Add g_signal_connect define to
106 make porting from gtk_signal_connect easy.
108 * gsignal.c (g_signal_emit_valist): Use G_TYPE_FROM_INSTANCE
109 (instance) instead of node->itype when initting the value.
111 2001-02-17 Havoc Pennington <hp@pobox.com>
113 Applied patch from Soeren Sandmann:
115 * gvaluetypes.c (g_value_get_string): G_CONST_RETURN
117 * gtype.c (g_type_name): G_CONST_RETURN
119 * gsignal.c (g_signal_name): G_CONST_RETURN
121 * gobject-query.c (main): const fix
123 Sat Feb 17 07:58:46 2001 Tim Janik <timj@gtk.org>
125 * genums.h (G_TYPE_IS_FLAGS): patch from sven to fixup
126 G_ENUM_CLASS_TYPE() macro.
128 Sat Feb 17 04:55:35 2001 Tim Janik <timj@gtk.org>
130 * gtype.[hc]: changed collect_format, collect_value() and lcopy_format,
131 lcopy_value() in the GTypeValueTable. the collect functions are now
132 called only once per value, collect_format/lcopy_format are strings
133 that enlist all necessary GTypeCValues to be varargs-collected.
135 * gvalue.h: ranamed STATIC_TAG to G_VALUE_NOCOPY_CONTENTS to indicate that
136 a value shouldn't copy its contents.
138 * gvaluecollector.h: changed G_VALUE_COLLECT() and G_VALUE_LCOPY()
139 macros to carry an additional argument (flags) that can be used
140 to pass G_VALUE_NOCOPY_CONTENTS along to the collection functions.
142 * *.c: adapted collect_value() and lcopy_value() functions to the new
143 prototypes, support G_VALUE_NOCOPY_CONTENTS where apropriate.
145 * gsignal.[hc]: introduced a G_SIGNAL_TYPE_STATIC_SCOPE flag that can
146 be passed along (ORed) with the parameter types, indicating that the
147 emission arguments are to be considered static for the scope of the
148 emission. should be used with care and only if the caller knows that
149 a parameter cannot be destroyed/freed from signal handlers connected
152 Fri Feb 16 07:10:44 2001 Tim Janik <timj@gtk.org>
156 (g_closure_sink): make closure sinking explicit.
159 (g_signal_connect_data):
160 (g_signal_connect_closure):
161 (g_signal_connect_closure_by_id):
162 (g_signal_newv): perform explicit closure sinking.
164 Thu Feb 8 00:31:45 2001 Tim Janik <timj@gtk.org>
166 * gtype.h: added G_TYPE_DEBUG_NONE for/from Eric Lemings ;)
168 2001-02-04 Tor Lillqvist <tml@iki.fi>
170 * gobject.def: Remove glib_debug_objects.
172 Sun Feb 4 07:30:53 2001 Tim Janik <timj@gtk.org>
174 * gtype.[hc]: changed g_type_init() to take debugging flags
175 initially, a combination of G_TYPE_DEBUG_OBJECTS and
176 G_TYPE_DEBUG_SIGNALS. using the G_TYPE_ prefix is a bit odd
177 here, but basically g_type_int() serves as initialization
178 fucntion for all of GType, GObject, GSignal, so what the heck.
180 * gobject.c: special case debugging code properly.
181 changed glib_trap_object_ref to g_trap_object_ref.
183 * gsignal.c: add signal emission debugging abilities, along with
184 a new trap object g_trap_instance_signals.
186 2001-02-04 Tor Lillqvist <tml@iki.fi>
188 * Makefile.am (progs_LDADD): Change order of libs to libgobject
189 first, then libglib. Needed for cygwin, says jbdoll@kepri.re.kr.
191 Wed Jan 31 06:19:49 2001 Tim Janik <timj@gtk.org>
193 * gparam.h: gtk-doc sucks for not dealing with #define inside enums.
195 * gtype.[hc]: added G_TYPE_FLAG_RESERVED_ID_BIT, a bit in the type
196 number that's supposed to be left untouched (preserved mainly
197 for the signal code).
199 * *.c: added thread safety code, based on an old patch from sebastian.
200 the remaining thread safety issues are now datalists on pspecs (to be
201 solved im gdataset.c) and gvalue.c where locking concerns value exchange
202 functionality only, and that's soon to be revised.
204 2001-01-27 Tor Lillqvist <tml@iki.fi>
206 * makefile.msc.in: Don't try to compile gmarshal.c on its own.
208 2001-01-24 <alexl@redhat.com>
210 * gclosure.c (g_closure_unref):
211 Don't leak closure->notifiers.
213 2001-01-05 Havoc Pennington <hp@redhat.com>
215 * gparamspecs.c (g_param_spec_enum): set the value_type in the
216 param spec; closes bug 40210
217 (g_param_spec_flags): ditto for flags
219 2001-01-03 Alexander Larsson <alexl@redhat.com>
222 Move glib_debug_objects out of the G_ENABLE_DEBUG #ifdef.
224 Thu Dec 28 11:36:44 2000 Tim Janik <timj@gtk.org>
226 * gbsearcharray.c (upper_power2): disable G_BSEARCH_ALIGN_POWER2
227 fucntionality if DISABLE_MEM_POOLS is defined.
229 * gtype.c: honour DISABLE_MEM_POOLS.
231 * gsignal.c (g_signal_init): flag signal key bsearch array with
232 G_BSEARCH_ALIGN_POWER2 to avoid excessive growth time. honour
235 * gparam.h: added G_PARAM_READWRITE alias for (G_PARAM_READABLE |
238 2000-12-15 Tor Lillqvist <tml@iki.fi>
240 * gobject.def: Update.
242 2000-12-15 Havoc Pennington <hp@pobox.com>
244 * gobject.c (g_object_do_class_init): use g_signal_newc
246 * gsignal.c (g_signal_newc): convenience function for signals
248 (g_signal_new_valist): added
249 (g_signal_new): removed
251 Fri Dec 15 04:40:23 2000 Tim Janik <timj@gtk.org>
253 * gparam.[hc]: add an instance member value_type so the default
254 value of the pspec class can be overridden.
256 2000-12-14 Tor Lillqvist <tml@iki.fi>
258 * makefile.mingw.in: Update, include parts from Makefile.am to
259 build gmarshal.[ch]. Some day, we won't need these separate
260 makefiles for Win32 compilation. I hope.
262 * makefile.msc.in: Update. No use trying to build gmarshal.[ch]
263 here, it would require Unixish tools. MSVC users building from CVS
264 sources are out of luck.
266 * gobject.def: Update.
268 Wed Dec 13 09:31:26 2000 Tim Janik <timj@gtk.org>
270 * gparamspecs.[hc]: add G_TYPE_PARAM_BOXED implementation.
272 * gobject.[hc]: minor fixes.
274 Tue Dec 12 23:38:02 2000 Tim Janik <timj@gtk.org>
276 * Makefile.am: _never_ touch oldest-source-stamp.
278 * gobject.[hc]: construct property handling fixes/improvements.
279 fixed trailer handling in get/set property.
281 * gparam.[hc]: implement param spec pool, got rid of param spec
282 hashtable. the most prominent change is that e deal with type
285 2000-12-12 Elliot Lee <sopwith@redhat.com>
288 . You have to 'touch oldest-source-stamp' if you want to avoid having
289 the Makefile constantly rebuild itself.
290 . Fix marshaller generation rules to work with srcdir != builddir
291 (there were issues with trying to run "./glib-genmarshal", etc.)
293 Mon Dec 11 04:44:11 2000 Tim Janik <timj@gtk.org>
295 * gboxed.c: fixed dealing with collection/lcopy of NULL values.
297 * gclosure.h: removed insane ramblings, added G_CALLBACK() a casting
300 * Makefile.am: cleanups, marshaller generation rules.
302 * gmarshal.[hc]: new files with GRuntime standard marshallers.
304 * glib-genmarshal.c: fix log domain, support gruntime standard
305 marshallers, suport G_TYPE_PARAM, come with extern "C" and
308 * glib-genmarshal.1: reflect glib-genmarshal.c updates.
310 * gobject.[hc]: implement object constructor. rework parameter
311 changed notification queueing, we support queue freezes now and
312 don't dispatch from an idle handler anymore.
313 parameter->property rename hassle.
314 implemented ::properties_changed and ::notify::* signals for
315 property change notification (the later supports property names
316 as details). added signal connection and named data properties.
317 (g_signal_connect_object): new function to setup while_alive
319 (g_object_class_install_property): sink properties now, since they
320 are initially floating.
321 (g_object_steal_data):
322 (g_object_set_data_full):
324 (g_object_get_data): set/get data by using g_datalist_*() functions
326 (g_object_queue_param_changed): nuked.
327 (g_object_freeze_notify): start queueing of property changes (freeze/
329 (g_object_notify): announce changes of a certain property directly.
330 (g_object_thaw_notify): process queue of property changes, therefore
331 emitting GObject::notify::detail with detail being the changed
333 (G_OBJECT_WARN_INVALID_PROPERTY_ID): saner macro variant of former
334 G_WARN_INVALID_PARAM_ID().
336 * gparam.[hc]: param specs are now initially floating and need to be
337 sunken with g_param_spec_sink(), support G_TYPE_PARAM values.
338 added G_PARAM_CONSTRUCT and G_PARAM_CONSTRUCT_ONLY parameter flags,
339 required by GObjectClass.constructor().
341 * gparamspecs.[hc]: added GParamSpecParam, GParamSpecPointer and
342 GParamSpecCCallback, param specs for G_TYPE_PARAM, G_TYPE_POINTER
343 and G_TYPE_CCALLBACK respectively.
345 * gsignal.[hc]: cleanups.
346 (signal_id_lookup): after walking the anchestry, try interfaces as well.
347 (g_signal_new): new function to create signals from varargs type list.
348 (g_signal_connect_closure): closure connection variant that works from
350 (g_signal_connect_data): c handler connection variant that works from
352 (g_signal_emit_valist): emit signal for an instance with paraneters
353 collected from a va_list.
354 (g_signal_emit): emit signal, taking parameters from varargs list.
355 (g_signal_emit_by_name): same as g_signal_emit, working from
357 (signal_emit_R): return whether return_value needs to be altered.
359 * gtype.[hc]: set log-domain to GRuntime, i'm slowly getting to all
360 the points that need to reflect the upcoming rename.
361 melt g_type_conforms_to() functionality into g_type_is_a(), as that
362 is what we really want (liskov substitution principle).
363 assorted changes to other files due to conforms_to->is_a.
365 * gvalue.[hc]: implemented g_value_set_instance() that sets a value
366 from an instantiatable type via the value_table's collect_value()
367 function (based on an idea from James Henstridge <james@daa.com.au>).
370 * gvaluetypes.[hc]: implement G_TYPE_CCALLBACK and G_TYPE_PARAM.
372 Wed Nov 29 13:30:05 2000 Tim Janik <timj@gtk.org>
374 * gsignal.c (handlers_find): fix elliots "logic fix" that dereferences
375 NULL nodes if C handlers are searched for specific signals.
377 2000-11-28 Elliot Lee <sopwith@redhat.com>
379 * gsignal.c: Fix warnings about possible use of uninitialized
380 variables, and fix logic that would leave 'node' unset in cases
381 that it might be used in.
383 * glib-genmarshal.c: Fix warning about printf format.
385 2000-11-28 Tor Lillqvist <tml@iki.fi>
387 * gboxed.c: Include <string.h> for memset ().
389 2000-11-22 Tor Lillqvist <tml@iki.fi>
391 * gobject.def: Update.
393 2000-11-20 Havoc Pennington <hp@redhat.com>
395 * gobject.c (g_object_get_data)
397 (g_object_set_data_full)
398 (g_object_steal_data): More convenient data-setting functions
400 Wed Nov 15 20:58:05 2000 Owen Taylor <otaylor@redhat.com>
402 * gtypemodule.c (g_type_module_use): If loading the
403 module fails, don't increment the use count.
405 Thu Nov 9 01:49:43 2000 Tim Janik <timj@gtk.org>
407 * gobject.h (G_WARN_INVALID_PARAM_ID): doh,
408 s/BSE_OBJECT_TYPE_NAME/G_OBJECT_TYPE_NAME/; reported by Maas-Maarten
409 Zeeman <maas@wanadoo.nl>.
411 Mon Nov 13 00:48:39 2000 Owen Taylor <otaylor@redhat.com>
413 * Makefile.am (EXTRA_DIST): Add glib-genmarshal.1
415 2000-11-11 Tor Lillqvist <tml@iki.fi>

423 Sun Nov 5 13:21:28 2000 Owen Taylor <otaylor@redhat.com>
425 * Makefile.am gtypemodule.[ch]: New basic implementation of
426 GTypePlugin interface as a GObject. Dynamically loaded modules can
427 register any number of types and interface on the module.
429 Sun Nov 5 10:25:40 2000 Owen Taylor <otaylor@redhat.com>
431 * gsignal.c (handlers_find): When appending handlers and
432 not matching on signal_id, use hlist->signal_id instead of
433 signal_id. Having the correct signal_id when unreffing
434 the handlers makes things work a lot better.
436 2000-11-05 Tor Lillqvist <tml@iki.fi>
438 * makefile.{mingw,msc}.in (gobject_OBJECTS): Add gtypeplugin.
440 * gobject.def: Update.
442 Sun Nov 5 05:22:55 2000 Tim Janik <timj@gtk.org>
445 fixed a bag full of subtle bugs of immensive screw-up potential in
446 handlers_find(), luckily no one found out about them yet ;)
447 fixed signal_handlers_foreach_matched_R() so it operates on an
448 initial handler list snapshot provided by handlers_find() to work
449 around general reentrancy problems and to avoid multiple callback()
450 invocations on the same handlers.
451 this code is now officially 80% bug free (10% remaining for interface
452 types, and 10% remaining for destroyed signals ;)
454 Sat Nov 4 02:01:33 2000 Tim Janik <timj@gtk.org>
456 * gsignal.c (_g_signals_destroy): valid signal nodes start out at 1.
458 * gtypeplugin.[hc]: new files holding a GTypePlugin interface
459 implementation that provides the API required by GType to deal with
460 dynamically loadable types.
462 * gtype.[hc]: displace any GTypePlugin business to gtypeplugin.h.
464 Fri Nov 3 07:35:00 2000 Tim Janik <timj@gtk.org>
466 * gsignal.[hc]: prefix internal functions with '_'. renamed
467 g_signal_connect_closure() to g_signal_connect_closure_by_id().
468 added g_signal_parse_name() to retrive signal_id and detail quark
469 from a signal name (internal).
471 Wed Nov 1 03:36:54 2000 Tim Janik <timj@gtk.org>
473 * gobject.c (g_object_base_class_finalize): destroy all signals that
474 the finalized obejct type introduced.
476 * gsignal.c (g_signals_destroy): don't require itype to have
479 * gobject.c (g_object_do_finalize): make sure all signal handlers
483 (g_signal_handler_find): only match on non-0 masks.
484 (g_signal_handlers_block_matched):
485 (g_signal_handlers_unblock_matched):
486 (g_signal_handlers_disconnect_matched): new functions to block/unblock
487 or disconnect handlers in groups.
489 2000-10-30 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
491 * gvalue.c (exchange_entries_equal), gparam.c (param_spec_equals):
492 made both functions return gboolean just for the little extra
493 standard conformance now that GEqualFunc is introduced.
495 Mon Oct 30 05:52:45 2000 Tim Janik <timj@gtk.org>
497 * gsignal.c (g_signal_list_ids): get rid of inline documentation owen
498 added, the doc system would ignore it anyways (for some reason not
501 Mon Oct 30 03:00:07 2000 Tim Janik <timj@gtk.org>
503 * gsignal.[hc] (g_signal_list_ids): renamed owen's g_type_signals(),
504 added required mutex locks.
506 Sun Oct 29 02:31:03 2000 Owen Taylor <otaylor@redhat.com>
508 * gsignal.c (g_type_signals): Fix problem where signals
509 with "_" in them appeared twice in the result array.
511 Sun Oct 29 01:58:44 2000 Owen Taylor <otaylor@redhat.com>
513 * gsignal.h: Add g_type_signals() - a function to list
514 all signals for a given type.
516 Sat Oct 28 00:28:09 2000 Tim Janik <timj@gtk.org>
518 * gclosure.c (g_closure_add_marshal_guards): fixed notifier position
519 for post_marshal guard which was off at 0.
521 Fri Oct 27 21:49:31 2000 Tim Janik <timj@gtk.org>
523 * gobject.[hc]: doh, fix argument order in for
524 g_cclosure_new_object_swap and g_cclosure_new_object.
526 2000-10-28 Tor Lillqvist <tml@iki.fi>
528 * makefile.{mingw,msc}.in: Make glib-genmarshal.exe.
530 * glib-genmarshal.c: Conditionalise include of unistd.h.
531 Include <io.h> on Win32.
533 * gobject.def: Add some missing entry points.
535 Fri Oct 27 16:33:41 2000 Tim Janik <timj@gtk.org>
537 * gsignal.[hc]: publically define GSignalInvocationHint structure
538 that gets passed in to closure invocations. added signal details.
539 renamed GSignalType to GSignalFlags to comply with conventions.
540 quite some cleanups and minor fixes. avoid uneccessary handler list
541 walks upon invokation of after handlers. relookup handler list for
542 restarted emissions. preliminary abort normal handler invokation if
543 after handler is encountered.
546 * gclosure.[hc]: moved invocation_hint to the end of the
547 g_closure_invoke() arguments as sugegsted by kenelson.
548 also made it a gpointer to be more generic. the invocation_hint
549 is a caller specific thing that can be used to pass additional
550 data in to closure invocations as documented with the caller
551 invoking the closure.
553 Fri Oct 27 05:35:14 2000 Tim Janik <timj@gtk.org>
555 * gobject.c (g_object_watch_closure): fixed realloc bug, reported
558 * gsignal.c (g_signal_newv): fixed deadlock scenarion where
559 g_signal_lookup() would be called with the signal lock being
560 held. reported by james henstridge.
562 * gclosure.c (g_closure_set_meta_marshal): fixed memcpy/overwrite bug
565 2000-10-26 Tor Lillqvist <tml@iki.fi>
567 * gbsearcharray.c (bsearch_array_insert): Fix gccisms (pointer
568 arithmetic on void pointer, label without statement following.
570 * gtype.c (type_node_fundamental_info): Don't apply unary minus to
571 result of sizeof operator, it can be unsigned. Cast first to
574 * gobject.def: Add new functions.
576 * makefile.{mingw,msc}.in: Add new objects.
578 2000-10-26 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
580 * Makefile.am: Remove empty SUBDIRS line _again_, as that _still_
581 prevents 'make dist' from working.
583 Wed Oct 25 19:11:03 2000 Owen Taylor <otaylor@redhat.com>
585 * gbsearcharray.h (g_bsearch_array_get_nth): Don't use implicit
586 casts from void * since this will get included from C++ too
589 Thu Oct 26 00:30:27 2000 Tim Janik <timj@gtk.org>
591 * gvaluetypes.[hc]: added g_value_set_static_string().
593 * gboxed.[hc]: const corrections. added g_value_set_static_boxed().
595 Wed Oct 25 20:27:02 2000 Tim Janik <timj@gtk.org>
597 * gtype.c (g_type_free_instance): for the moment, freeing object
598 structures will fill their memory portion with 0xAA. there's a
599 FIXME there, remove this line at a later point.
601 Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org>
604 * glib-genmarshal.c: added publically installed marshaller generator.
606 * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain
607 interface VTable from instances.
609 Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org>
611 * gobject.[hc]: new functions for closure maintenance:
612 (g_object_watch_closure): maintain validity of the object and
613 the closure for objects that are used as data part of a closure.
614 (g_cclosure_new_object): convenience function to create C closures
615 that have an object as data argument.
616 (g_closure_new_object): convenience function to create closures
617 that have an object as data argument.
619 * gclosure.[hc]: implementation of GClosure mechanism.
620 a closure is basically an encapsulation of a callback function
621 and its environment. ideally, most places supporting callback
622 functions will simply take a GClosure* pointer and thus unify
623 callback environments wrg destroy notification etc.
624 GClosure provides destroy notifiers for arbitrary data pointers,
625 reference counting, invalidation notification (it can be invalidated
626 which is merely a deactivate state) and a marshallinbg abstraction.
627 GCClosure is also provided in these files, they present a specialized
628 GClosure implementation for C language callbacks.
630 * genum.c: macro cleanups.
632 * gboxed.[hc]: new files, for boxed type abstraction.
633 (g_boxed_copy): copy a boxed structure
634 (g_boxed_free): free a boxed structure
636 (g_value_get_boxed): standard GValue functions for boxed types
637 (g_boxed_type_register_static): convenience function for easy
638 introduction of new G_TYPE_BOXED derivatives.
640 * gparam.[hc]: introduced g_param_type_register_static(), a short hand
641 for creation of new GParamSpec derived types.
643 * gtype.[hc]: many fixes, introduced ability to flag individual
644 type nodes as ABSTRACT upon registration, added value_peek_pointer()
645 to the value table to peek at GValue contents as a pointer for types
646 that support this. fixed up GValue checks.
648 * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer()
649 to peek at the value contents as pointer.
651 * *.[hc]: adaptions to type macro fixes and changes in the type
654 * many const corrections over the place.
656 Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org>
658 * gtype.c (g_type_conforms_to): this function basically behaves like
659 and is_a check, except that it _additionally_ features interfaces
660 for instantiatable types. enforce this in the second branch as well
661 (`type' conforms_to `type') even if `type' is not an interface type.
663 Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org>
665 * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb.
669 * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and
670 suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT
673 Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org>
675 * gbsearcharray.[hc]: long standing needed generic implementation
676 of a binary searchable, sorted and dynamically sized array.
678 2000-10-15 Raja R Harinath <harinath@cs.umn.edu>
680 * Makefile.am (BUILT_EXTRA_DIST): New variable.
681 (dist-hook): Handle $(BUILT_EXTRA_DIST).

684 2000-09-29 Martin Baulig <baulig@suse.de>
686 Several minor ANSI C fixes.
689 * gtype.c (type_class_init):
690 `(gpointer) bnode->data->class.class_init_base'
691 in call to g_slist_prepend() and
692 'GBaseInitFunc class_init_base = (GBaseInitFunc) slist->data'.
694 * gobject.c: Put text following #endif into comments.
696 2000-09-25 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
698 * Makefile.am: Remove empty SUBDIRS line, as that prevents make
701 Sat Sep 9 20:04:13 2000 Owen Taylor <otaylor@redhat.com>
703 * gobject.c (g_object_last_unref): Move call to
704 g_type_free_instance() here from g_object_do_finalize,
705 since g_type_free_instance() can unload the object's
708 2000-07-27 Tor Lillqvist <tml@iki.fi>
710 * gobject.c: No, don't mark glib_debug_objects for export here,
711 it's handled specially in gtktypeutils.c.
713 * gobject.def: Export g_type_fundamental_last (the function).
715 2000-07-26 Tor Lillqvist <tml@iki.fi>
718 * gobject.c: Mark glib_debug_objects for export/import as it is
721 Sun Jul 23 17:23:35 2000 Tim Janik <timj@gtk.org>
723 * gtype.[hc]: make g_type_fundamental_last() a function, avoiding all
724 that extern variable clutter and avoiding further problems with thread
727 2000-07-19 Tor Lillqvist <tml@iki.fi>
732 * gtype.c: Shut up Sun's picky compiler.
734 2000-07-14 Tor Lillqvist <tml@iki.fi>
736 * gobject.def: Add g_type_get_plugin.
738 Thu Jul 13 02:07:54 2000 Tim Janik <timj@gtk.org>
740 * gparam.c (g_param_value_defaults): default initialize the temporary
741 default value, instead of nuking the caller's value contents.
743 2000-07-11 Raja R Harinath <harinath@cs.umn.edu>
745 * gtype.c (g_type_get_plugin): Don't return just 0 or 1.
747 Tue Jul 11 02:48:13 2000 Tim Janik <timj@gtk.org>
749 * gtype.[hc]: removed g_type_is_dynamic() and added g_type_get_plugin().
751 2000-07-10 Tor Lillqvist <tml@iki.fi>
753 * gobject-query.c: Include ../config.h for HAVE_UNISTD_H. Use it
754 to guard inclusion of <unistd.h>.
756 * gtype.h: Fix copy-paste errors in the ifdefs on how to declare a
757 variable for export. Call the macro GOBJECT_VAR.
759 * gtype.c: Declare _g_type_fundamental_last for export here, too.
760 (type_node_any_new): Use only constant expressions for sizeof
761 operator (for instance MSVC requires this).
763 * makefile.mingw.in: Define GOBJECT_COMPILATION.
765 Sun Jul 9 21:21:46 2000 Owen Taylor <otaylor@redhat.com>
767 * genums.c: Move string.h include into the .c file
768 instead of where it was in the .h file by mistake.
770 Thu Jul 6 15:30:27 2000 Owen Taylor <otaylor@redhat.com>
772 * Makefile.am (EXTRA_DIST): dist fixes.
774 * gobject.c: Add a global variable glib_debug_objects
775 (not in header file) to control object tracing.
777 2000-07-01 Tor Lillqvist <tml@iki.fi>
779 * gobject.def: Update added and renamed entry points.
781 * makefile.mingw.in: Add gvaluetypes.o.
783 Thu Jun 29 16:02:07 2000 Owen Taylor <otaylor@redhat.com>
785 * gobject.c:include string.h for memset
786 * genums.h: include string.h for strcpy
787 * gvalue.c: include string.h for memset, memcpy.
789 Sat Jun 24 23:03:04 2000 Tim Janik <timj@gtk.org>
791 * gtype.[hc]: provide G_TYPE_CHAR, G_TYPE_UCHAR, G_TYPE_BOOLEAN,
792 G_TYPE_INT, G_TYPE_UINT, G_TYPE_LONG, G_TYPE_ULONG, G_TYPE_FLOAT,
793 G_TYPE_DOUBLE and G_TYPE_STRING fundamental types.
794 added a GTypeValueTable* pointer to GTypeInfo structure for types
795 to implement GValue handling functions.
796 GTypeValueTable contains the following members:
797 value_init(): initialize a GValue structure.
798 value_free(): free GValue structure contents (optional).
799 value_copy(): copy one GValue contents to another GValue structure of
800 collect_type: varargs collection type for the first variable argument
801 to be collected by collect_value().
802 collect_value(): variable arguments collection function (optional).
803 lcopy_type: varargs collection type for the first variable argument
804 to be location copyied by lcopy_value().
805 lcopy_value(): variable arguments location copy function (optional).
806 g_type_value_table_peek(): new function to retrive the GTypeValueTable*
807 for a type node. ValueTables get inherited from parent types, unless
808 overridden through the GTypeInfo structure. internally, GTypeValueTable
809 support means an added overhead of one pointer per static or used
811 g_type_add_class_cache_func(): provide a cache_func/data pair to be
812 called prior to a type nodes last_unref() function, this can be used
813 to prevent premature class destruction. multiple installed cache_func()
814 will be chained upon last_unref() untill one of them returns TRUE.
815 the cache_func()s have to check the class id passed in to figure whether
816 they actually want to cache the class of this type (since all classes
817 are routed through the cache_func() chain).
818 g_type_remove_class_cache_func(): remove a previously installed
819 cache_func/data pair. the cache maintained by this function has to be
820 clear when calling g_type_remove_class_cache_func() to avoid leaks.
821 g_type_class_unref_uncached(): class unref function for cache_func()
822 implementations, unreferences a class omitting the cache chain (and
823 therefore unref->cache->unref->... loops).
825 * gvaluetypes.[hc]: provide the value setters/getters for the primitive
826 fundamental types boolean, char, uchar, int, uint, long, ulong, float,
829 * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a
830 GTypeValueTable is provided for this type.
831 removed g_value_init_default(), g_value_validate(), g_value_defaults(),
832 g_value_set_default() and g_values_cmp() as these are supplied by the
834 moved g_values_exchange() into the "implementation details" section,
835 since it just provides the underlying functionality for
838 * gvaluecollector.h: renamed the varargs value container from
839 GParamCValue to GTypeCValue as the value collection methods are
840 supplied by the type system now.
841 G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to
842 G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a
843 GParamSpec structure now.
845 * genums.h: macros cleanups/fixes.
847 * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type
848 and assorted g_value_{s|g}et_{enum|flags}() implementations.
851 provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods
852 and g_value_{s|g}et_object().
854 * gparam.[hc]: reduced class to value_set_default(),
855 value_validate() and values_cmp(). also parameters now need to fill
856 in a GType value_type; field to indicate the GValue type they
857 are handling. provide g_param_value_set_default(),
858 g_param_value_defaults(), g_param_value_validate() and
859 g_param_values_cmp().
861 * gparamspecs.[hc]: got rid of the g_value_* functions and
862 the G_IS_VALUE_* macros. adapted param spec implementations
863 according to the GParamSpecClass changes.
865 Sat Jun 10 08:38:27 2000 Tim Janik <timj@gtk.org>
867 * gtype.c (type_class_init): fetch the nth iface entry of the
868 type node in the nth loop iteration, not alwys the first.
869 bug discovered by Walt Pohl <cher@suitware.com>.
870 (type_data_finalize_class_ifaces): same here, cut and paste
873 Wed Jun 7 09:21:05 2000 Owen Taylor <otaylor@redhat.com>
875 * Makefile.am (INCLUDES): Add top_builddir so glibconfig.h
876 is found properly when build srcdir != builddir. (Patch from
879 2000-05-13 Tor Lillqvist <tml@iki.fi>
883 * gobject.rc.in: New files, for Win32 (mingw) build.
885 * Makefile.am: Add to EXTRA_DIST. Add rules to produce the
886 corresponding non-*.in files.
888 * gtype.h: (Win32:) Mark _g_type_fundamental_last for
889 export/import from DLL.
891 Fri May 5 01:15:48 2000 Tim Janik <timj@gtk.org>
893 * gtype.h: add reserved fundamental ids for gtk types (for transition
894 time). added G_TYPE_FUNDAMENTAL_MAX for gtk.
896 Mon Apr 17 20:45:50 2000 Tim Janik <timj@gtk.org>
898 * glib-gobject.c (g_object_base_class_finalize): oops, don't unset
899 n_params prior to destructing them.
901 Tue Apr 11 04:28:10 2000 Tim Janik <timj@gtk.org>
903 * fixed a couple of bugs in the initial parameter/object
904 implementations, after getting beast running on GObject and GValue.
906 Fri Apr 7 04:27:49 2000 Tim Janik <timj@gtk.org>
908 * glib-gobject.[hc]: completed parameter set/get implementations,
909 along with asyncronous parameter changed notification queue.
911 Sun Apr 2 04:54:36 2000 Tim Janik <timj@gtk.org>
913 * glib-gobject.[hc]: GObject implementation, that is facilities
914 for setting/getting quarked data and reference counting.
916 * glib-gparamspecs.[hc]: first actuall parameter implementations
917 for GLib, so far we have: char, uchar, bool, int, uint, long,
918 ulong, enum, flags, float, double, string and object. each of these
919 GParamSpecs is a new instantiatable type in its own respect,
920 so the .c file derives 13 new types from G_TYPE_PARAM and
921 defines over 50 (*2) conversion facilities.
923 * glib-gvaluecollector.h: generic varargs handling stubs for
924 GParamSpecs, private header file (does get installed for
925 inclusion into user code though).
927 * glib-gvalue.[hc]: GValue functionality implementation.
929 * glib-gparam.[hc]: basis GParamSpec implementation for
930 the virtual base type G_TYPE_PARAM.
932 * glib-genums.[hc]: enum/flags type implementation, based on
935 * glib-gtype.[hc]: GLib Type System implementation, heavily
936 based on BSE's dynamic type system.
