glib/gobject/ChangeLog

2001-02-04  Tor Lillqvist  <tml@iki.fi>

	* gobject.def: Remove glib_debug_objects.

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.

2001-02-04  Tor Lillqvist  <tml@iki.fi>

	* Makefile.am (progs_LDADD): Change order of libs to libgobject
	first, then libglib. Needed for cygwin, says jbdoll@kepri.re.kr.

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.

2001-01-27  Tor Lillqvist  <tml@iki.fi>

	* makefile.msc.in: Don't try to compile gmarshal.c on its own.

2001-01-24    <alexl@redhat.com>

	* gclosure.c (g_closure_unref):
	Don't leak closure->notifiers.

2001-01-05  Havoc Pennington  <hp@redhat.com>

	* gparamspecs.c (g_param_spec_enum): set the value_type in the
	param spec; closes bug 40210
	(g_param_spec_flags): ditto for flags

2001-01-03  Alexander Larsson  <alexl@redhat.com>

	* gobject.c:
	Move glib_debug_objects out of the G_ENABLE_DEBUG #ifdef.

Thu Dec 28 11:36:44 2000  Tim Janik  <timj@gtk.org>

	* gbsearcharray.c (upper_power2): disable G_BSEARCH_ALIGN_POWER2
	fucntionality if DISABLE_MEM_POOLS is defined.

	* gtype.c: honour DISABLE_MEM_POOLS.

	* gsignal.c (g_signal_init): flag signal key bsearch array with
	G_BSEARCH_ALIGN_POWER2 to avoid excessive growth time. honour
	DISABLE_MEM_POOLS.

	* gparam.h: added G_PARAM_READWRITE alias for (G_PARAM_READABLE |
	                                               G_PARAM_WRITABLE).

2000-12-15  Tor Lillqvist  <tml@iki.fi>

	* gobject.def: Update.

2000-12-15  Havoc Pennington  <hp@pobox.com>

	* gobject.c (g_object_do_class_init): use g_signal_newc

	* gsignal.c (g_signal_newc): convenience function for signals
	created from C
	(g_signal_new_valist): added
	(g_signal_new): removed

Fri Dec 15 04:40:23 2000  Tim Janik  <timj@gtk.org>

	* gparam.[hc]: add an instance member value_type so the default
	value of the pspec class can be overridden.

2000-12-14  Tor Lillqvist  <tml@iki.fi>

	* makefile.mingw.in: Update, include parts from Makefile.am to
	build gmarshal.[ch]. Some day, we won't need these separate
	makefiles for Win32 compilation. I hope.

	* makefile.msc.in: Update. No use trying to build gmarshal.[ch]
	here, it would require Unixish tools. MSVC users building from CVS
	sources are out of luck.
	
	* gobject.def: Update.

Wed Dec 13 09:31:26 2000  Tim Janik  <timj@gtk.org>

	* gparamspecs.[hc]: add G_TYPE_PARAM_BOXED implementation.

	* gobject.[hc]: minor fixes.

Tue Dec 12 23:38:02 2000  Tim Janik  <timj@gtk.org>

	* Makefile.am: _never_ touch oldest-source-stamp.
	
	* gobject.[hc]: construct property handling fixes/improvements.
	fixed trailer handling in get/set property.
	
	* gparam.[hc]: implement param spec pool, got rid of param spec
	hashtable. the most prominent change is that e deal with type
	prefixes here.
	
2000-12-12  Elliot Lee  <sopwith@redhat.com>

	* Makefile.am:
	  . You have to 'touch oldest-source-stamp' if you want to avoid having
	  the Makefile constantly rebuild itself.
	  . Fix marshaller generation rules to work with srcdir != builddir
	    (there were issues with trying to run "./glib-genmarshal", etc.)

Mon Dec 11 04:44:11 2000  Tim Janik  <timj@gtk.org>

	* gboxed.c: fixed dealing with collection/lcopy of NULL values.

	* gobject.[hc]: implement object constructor. rework parameter
	changed notification queueing, we support queue freezes now and
	don't dispatch from an idle handler anymore.
	parameter->property rename hassle.
	implemented ::properties_changed and ::notify::* signals for
	property change notification (the later supports property names
	as details). added signal connection and named data properties.
	(g_signal_connect_object): new function to setup while_alive
	connections.
	(g_object_class_install_property): sink properties now, since they
	are initially floating.
	(g_object_steal_data):
	(g_object_set_data_full):
	(g_object_set_data):
	(g_object_get_data): set/get data by using g_datalist_*() functions
	directly.
	(g_object_queue_param_changed): nuked.
	(g_object_freeze_notify): start queueing of property changes (freeze/
	thaw calls stack).
	(g_object_notify): announce changes of a certain property directly.
	(g_object_thaw_notify): process queue of property changes, therefore
	emitting GObject::notify::detail with detail being the changed
	properties names.
	(G_OBJECT_WARN_INVALID_PROPERTY_ID): saner macro variant of former
	G_WARN_INVALID_PARAM_ID().
	
	* gparam.[hc]: param specs are now initially floating and need to be
	sunken with g_param_spec_sink(), support G_TYPE_PARAM values.
	added G_PARAM_CONSTRUCT and G_PARAM_CONSTRUCT_ONLY parameter flags,
	required by GObjectClass.constructor().
	
	* gparamspecs.[hc]: added GParamSpecParam, GParamSpecPointer and

	* gtype.[hc]: set log-domain to GRuntime, i'm slowly getting to all
	the points that need to reflect the upcoming rename.
	melt g_type_conforms_to() functionality into g_type_is_a(), as that
	is what we really want (liskov substitution principle).
	assorted changes to other files due to conforms_to->is_a.

	* gvalue.[hc]: implemented g_value_set_instance() that sets a value
	from an instantiatable type via the value_table's collect_value()
	function (based on an idea from James Henstridge <james@daa.com.au>).
	cleanups/fixes.
	
	* gvaluetypes.[hc]: implement G_TYPE_CCALLBACK and G_TYPE_PARAM.

	NULL nodes if C handlers are searched for specific signals.

2000-11-28  Elliot Lee  <sopwith@redhat.com>

	(g_object_set_data_full)
	(g_object_steal_data): More convenient data-setting functions

Wed Nov 15 20:58:05 2000  Owen Taylor  <otaylor@redhat.com>

	* gtypemodule.c (g_type_module_use): If loading the
	module fails, don't increment the use count.

Thu Nov  9 01:49:43 2000  Tim Janik  <timj@gtk.org>

	* gobject.h (G_WARN_INVALID_PARAM_ID): doh,
	s/BSE_OBJECT_TYPE_NAME/G_OBJECT_TYPE_NAME/; reported by Maas-Maarten
	Zeeman <maas@wanadoo.nl>.

	GTypePlugin interface as a GObject. Dynamically loaded modules can
	register any number of types and interface on the module.

Sun Nov  5 10:25:40 2000  Owen Taylor  <otaylor@redhat.com>

	* gsignal.c (handlers_find): When appending handlers and
	not matching on signal_id, use hlist->signal_id instead of 
	signal_id. Having the correct signal_id when unreffing
	the handlers makes things work a lot better.

2000-11-05  Tor Lillqvist  <tml@iki.fi>

	* makefile.{mingw,msc}.in (gobject_OBJECTS): Add gtypeplugin.

	* gobject.def: Update.

Sun Nov  5 05:22:55 2000  Tim Janik  <timj@gtk.org>

	* gsignal.c:
	fixed a bag full of subtle bugs of immensive screw-up potential in
	handlers_find(), luckily no one found out about them yet ;)
	fixed signal_handlers_foreach_matched_R() so it operates on an
	initial handler list snapshot provided by handlers_find() to work
	around general reentrancy problems and to avoid multiple callback()
	invocations on the same handlers.
	this code is now officially 80% bug free (10% remaining for interface
	types, and 10% remaining for destroyed signals ;)
	
Sat Nov  4 02:01:33 2000  Tim Janik  <timj@gtk.org>

	* gsignal.c (_g_signals_destroy): valid signal nodes start out at 1.

	* gtypeplugin.[hc]: new files holding a GTypePlugin interface
	implementation that provides the API required by GType to deal with
	dynamically loadable types.

	* gtype.[hc]: displace any GTypePlugin business to gtypeplugin.h.

Fri Nov  3 07:35:00 2000  Tim Janik  <timj@gtk.org>

	* gsignal.[hc]: prefix internal functions with '_'. renamed
	g_signal_connect_closure() to g_signal_connect_closure_by_id().
	added g_signal_parse_name() to retrive signal_id and detail quark
	from a signal name (internal).

Wed Nov  1 03:36:54 2000  Tim Janik  <timj@gtk.org>

	* gobject.c (g_object_base_class_finalize): destroy all signals that
	the finalized obejct type introduced.

	* gsignal.c (g_signals_destroy): don't require itype to have
	signals.

	* gobject.c (g_object_do_finalize): make sure all signal handlers
	are destroyed.

	* gsignal.[hc]:
	(g_signal_handler_find): only match on non-0 masks.
	(g_signal_handlers_block_matched):
	(g_signal_handlers_unblock_matched):
	(g_signal_handlers_disconnect_matched): new functions to block/unblock
	or disconnect handlers in groups.

2000-10-30  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* gvalue.c (exchange_entries_equal), gparam.c (param_spec_equals):
	made both functions return gboolean just for the little extra
	standard conformance now that GEqualFunc is introduced.

Mon Oct 30 05:52:45 2000  Tim Janik  <timj@gtk.org>

	* gsignal.c (g_signal_list_ids): get rid of inline documentation owen
	added, the doc system would ignore it anyways (for some reason not
	aparent to me).

Mon Oct 30 03:00:07 2000  Tim Janik  <timj@gtk.org>

	* gsignal.[hc] (g_signal_list_ids): renamed owen's g_type_signals(),
	added required mutex locks.

Sun Oct 29 01:58:44 2000  Owen Taylor  <otaylor@redhat.com>

	* gsignal.h: Add g_type_signals() - a function to list
	all signals for a given type.

Fri Oct 27 16:33:41 2000  Tim Janik  <timj@gtk.org>

	* gsignal.[hc]: publically define GSignalInvocationHint structure
	that gets passed in to closure invocations. added signal details.
	renamed GSignalType to GSignalFlags to comply with conventions.
	quite some cleanups and minor fixes. avoid uneccessary handler list
	walks upon invokation of after handlers. relookup handler list for
	restarted emissions. preliminary abort normal handler invokation if
	after handler is encountered.

	* glib-genmarshal.c:
	* gclosure.[hc]: moved invocation_hint to the end of the
	g_closure_invoke() arguments as sugegsted by kenelson.
	also made it a gpointer to be more generic. the invocation_hint
	is a caller specific thing that can be used to pass additional
	data in to closure invocations as documented with the caller
	invoking the closure.

Fri Oct 27 05:35:14 2000  Tim Janik  <timj@gtk.org>

	* gobject.c (g_object_watch_closure): fixed realloc bug, reported

	* makefile.{mingw,msc}.in: Add new objects.

2000-10-26  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* Makefile.am: Remove empty SUBDIRS line _again_, as that _still_
	prevents 'make dist' from working.

Wed Oct 25 19:11:03 2000  Owen Taylor  <otaylor@redhat.com>

	* gbsearcharray.h (g_bsearch_array_get_nth): Don't use implicit
	casts from void * since this will get included from C++ too
	at times.
	
Thu Oct 26 00:30:27 2000  Tim Janik  <timj@gtk.org>

	* gvaluetypes.[hc]: added g_value_set_static_string().

	* gboxed.[hc]: const corrections. added g_value_set_static_boxed().

Wed Oct 25 20:27:02 2000  Tim Janik  <timj@gtk.org>

	* gtype.c (g_type_free_instance): for the moment, freeing object
	structures will fill their memory portion with 0xAA. there's a
	FIXME there, remove this line at a later point.

Tue Oct 24 23:10:26 2000  Tim Janik  <timj@gtk.org>

	* glib-genmarshal.1:
	* glib-genmarshal.c: added publically installed marshaller generator.

	* gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain
	interface VTable from instances.

Mon Oct 23 08:28:15 2000  Tim Janik  <timj@gtk.org>

	* gobject.[hc]: new functions for closure maintenance:
	(g_object_watch_closure): maintain validity of the object and
	the closure for objects that are used as data part of a closure.
	(g_cclosure_new_object): convenience function to create C closures
	that have an object as data argument.
	(g_closure_new_object): convenience function to create closures
	that have an object as data argument.

	* gclosure.[hc]: implementation of GClosure mechanism.
	a closure is basically an encapsulation of a callback function
	and its environment. ideally, most places supporting callback
	functions will simply take a GClosure* pointer and thus unify
	callback environments wrg destroy notification etc.
	GClosure provides destroy notifiers for arbitrary data pointers,
	reference counting, invalidation notification (it can be invalidated
	which is merely a deactivate state) and a marshallinbg abstraction.
	GCClosure is also provided in these files, they present a specialized
	GClosure implementation for C language callbacks.

	* genum.c: macro cleanups.
	
	* gboxed.[hc]: new files, for boxed type abstraction.
	(g_boxed_copy): copy a boxed structure
	(g_boxed_free): free a boxed structure
	(g_value_set_boxed):
	(g_value_get_boxed): standard GValue functions for boxed types
	(g_boxed_type_register_static): convenience function for easy
	introduction of new G_TYPE_BOXED derivatives.

	* gparam.[hc]: introduced g_param_type_register_static(), a short hand
	for creation of new GParamSpec derived types.

	* gtype.[hc]: many fixes, introduced ability to flag individual
	type nodes as ABSTRACT upon registration, added value_peek_pointer()
	to the value table to peek at GValue contents as a pointer for types
	that support this. fixed up GValue checks.

	* gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer()
	to peek at the value contents as pointer.

	* *.[hc]: adaptions to type macro fixes and changes in the type
	registration API.

	* many const corrections over the place.

Sat Oct 21 02:49:56 2000  Tim Janik  <timj@gtk.org>

	* gtype.c (g_type_conforms_to): this function basically behaves like
	and is_a check, except that it _additionally_ features interfaces
	for instantiatable types. enforce this in the second branch as well
	(`type' conforms_to `type') even if `type' is not an interface type.

Fri Oct 20 15:31:04 2000  Tim Janik  <timj@gtk.org>

	* gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb.

	* gtype.[hc]:
	* gobject.c:
	* gvaluetypes.c: added GTypeValueTable.value_peek_pointer and
	suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT
	and G_TYPE_POINTER.

Mon Aug 21 04:13:37 2000  Tim Janik  <timj@gtk.org>

	* gbsearcharray.[hc]: long standing needed generic implementation
	of a binary searchable, sorted and dynamically sized array.

2000-10-15  Raja R Harinath  <harinath@cs.umn.edu>

	* Makefile.am (BUILT_EXTRA_DIST): New variable.
	(dist-hook): Handle $(BUILT_EXTRA_DIST).
	(*): Remove traces of @STRIP_{BEGIN,END}@.
	
2000-09-29  Martin Baulig  <baulig@suse.de>
	
	Several minor ANSI C fixes.

	Added missing casts:
	* gtype.c (type_class_init): 
	`(gpointer) bnode->data->class.class_init_base'
	in call to g_slist_prepend() and
	'GBaseInitFunc class_init_base = (GBaseInitFunc) slist->data'.

	* gobject.c: Put text following #endif into comments.

2000-09-25  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* Makefile.am: Remove empty SUBDIRS line, as that prevents make
	dist from working.

Sat Sep  9 20:04:13 2000  Owen Taylor  <otaylor@redhat.com>

	* gobject.c (g_object_last_unref): Move call to
	g_type_free_instance() here from g_object_do_finalize,
	since g_type_free_instance() can unload the object's
	implementation.

2000-07-27  Tor Lillqvist  <tml@iki.fi>

	* gobject.c: No, don't mark glib_debug_objects for export here,
	it's handled specially in gtktypeutils.c.

	used by GTK+.

Sun Jul 23 17:23:35 2000  Tim Janik  <timj@gtk.org>

	* gtype.[hc]: make g_type_fundamental_last() a function, avoiding all
	that extern variable clutter and avoiding further problems with thread
	safety.

2000-07-19  Tor Lillqvist  <tml@iki.fi>

	* gparam.h
	* gvalue.h
	* gparam.c
	* gtype.c: Shut up Sun's picky compiler.

2000-07-14  Tor Lillqvist  <tml@iki.fi>

	* gobject.def: Add g_type_get_plugin.

Thu Jul 13 02:07:54 2000  Tim Janik  <timj@gtk.org>

	* gparam.c (g_param_value_defaults): default initialize the temporary
	default value, instead of nuking the caller's value contents.

2000-07-11  Raja R Harinath  <harinath@cs.umn.edu>

	* gtype.c (g_type_get_plugin): Don't return just 0 or 1.

Tue Jul 11 02:48:13 2000  Tim Janik  <timj@gtk.org>

	* gtype.[hc]: removed g_type_is_dynamic() and added g_type_get_plugin().

2000-07-10  Tor Lillqvist  <tml@iki.fi>

	* gobject-query.c: Include ../config.h for HAVE_UNISTD_H. Use it
	to guard inclusion of <unistd.h>.

	* gtype.h: Fix copy-paste errors in the ifdefs on how to declare a
	variable for export. Call the macro GOBJECT_VAR.

	* gtype.c: Declare _g_type_fundamental_last for export here, too.
	(type_node_any_new): Use only constant expressions for sizeof
	operator (for instance MSVC requires this).

	* makefile.mingw.in: Define GOBJECT_COMPILATION.

Sun Jul  9 21:21:46 2000  Owen Taylor  <otaylor@redhat.com>

	* genums.c: Move string.h include into the .c file
	instead of where it was in the .h file by mistake.

Thu Jul  6 15:30:27 2000  Owen Taylor  <otaylor@redhat.com>

	* Makefile.am (EXTRA_DIST): dist fixes.

	* gobject.c: Add a global variable glib_debug_objects
	(not in header file) to control object tracing.

2000-07-01  Tor Lillqvist  <tml@iki.fi>

	* gobject.def: Update added and renamed entry points.

	* makefile.mingw.in: Add gvaluetypes.o.

Thu Jun 29 16:02:07 2000  Owen Taylor  <otaylor@redhat.com>

	* gobject.c:include string.h for memset
	* genums.h: include string.h for strcpy
	* gvalue.c: include string.h for memset, memcpy.

Sat Jun 24 23:03:04 2000  Tim Janik  <timj@gtk.org>

	* gtype.[hc]: provide G_TYPE_CHAR, G_TYPE_UCHAR, G_TYPE_BOOLEAN,
	G_TYPE_INT, G_TYPE_UINT, G_TYPE_LONG, G_TYPE_ULONG, G_TYPE_FLOAT,
	G_TYPE_DOUBLE and G_TYPE_STRING fundamental types.
	added a GTypeValueTable* pointer to GTypeInfo structure for types
	to implement GValue handling functions.
	GTypeValueTable contains the following members:
	  value_init(): initialize a GValue structure.
	  value_free(): free GValue structure contents (optional).
	  value_copy(): copy one GValue contents to another GValue structure of
	  collect_type: varargs collection type for the first variable argument
	  to be collected by collect_value().
	  collect_value(): variable arguments collection function (optional).
	  lcopy_type: varargs collection type for the first variable argument
	  to be location copyied by lcopy_value().
	  lcopy_value(): variable arguments location copy function (optional).
	g_type_value_table_peek(): new function to retrive the GTypeValueTable*
	for a type node. ValueTables get inherited from parent types, unless
	overridden through the GTypeInfo structure. internally, GTypeValueTable
	support means an added overhead of one pointer per static or used
	dynamic type node.
	g_type_add_class_cache_func(): provide a cache_func/data pair to be
	called 	prior to a type nodes last_unref() function, this can be used
	to prevent premature class destruction. multiple installed cache_func()
	will be chained upon last_unref() untill one of them returns TRUE.
	the cache_func()s have to check the class id passed in to figure whether
	they actually want to cache the class of this type (since all classes
	are routed through the cache_func() chain).
	g_type_remove_class_cache_func(): remove a previously installed
	cache_func/data pair. the cache maintained by this function has to be
	clear when calling g_type_remove_class_cache_func() to avoid leaks.
	g_type_class_unref_uncached(): class unref function for cache_func()
	implementations, unreferences a class omitting the cache chain (and
	therefore unref->cache->unref->... loops).

	* gvaluetypes.[hc]: provide the value setters/getters for the primitive
	fundamental types boolean, char, uchar, int, uint, long, ulong, float,
	double and string.

	* gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a
	GTypeValueTable is provided for this type.
	removed g_value_init_default(), g_value_validate(), g_value_defaults(),
	g_value_set_default() and g_values_cmp() as these are supplied by the
	GParamSpec API now.
	moved g_values_exchange() into the "implementation details" section,
	since it just provides the underlying functionality for
	g_value_convert().

	* gvaluecollector.h: renamed the varargs value container from
	GParamCValue to GTypeCValue as the value collection methods are
	supplied by the type system now.
	G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to
	G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a
	GParamSpec structure now.

	* genums.h: macros cleanups/fixes.

	* genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type
	and assorted g_value_{s|g}et_{enum|flags}() implementations.

	* gobject.[hc]:
	provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods
	and g_value_{s|g}et_object().

	* gparam.[hc]: reduced class to value_set_default(),
	value_validate() and values_cmp(). also parameters now need to fill
	in a GType value_type; field to indicate the GValue type they
	are handling. provide g_param_value_set_default(),
	g_param_value_defaults(), g_param_value_validate() and
	g_param_values_cmp().

	* gparamspecs.[hc]: got rid of the g_value_* functions and
	the G_IS_VALUE_* macros. adapted param spec implementations
	according to the GParamSpecClass changes.

Sat Jun 10 08:38:27 2000  Tim Janik  <timj@gtk.org>

	* gtype.c (type_class_init): fetch the nth iface entry of the
	type node in the nth loop iteration, not alwys the first.
	bug discovered by Walt Pohl <cher@suitware.com>.
	(type_data_finalize_class_ifaces): same here, cut and paste
	rulez.

Wed Jun  7 09:21:05 2000  Owen Taylor  <otaylor@redhat.com>

	* Makefile.am (INCLUDES): Add top_builddir so glibconfig.h
	is found properly when build srcdir != builddir. (Patch from
	Eric Lemings)

2000-05-13  Tor Lillqvist  <tml@iki.fi>

	* makefile.mingw.in
	* gobject.def
	* gobject.rc.in: New files, for Win32 (mingw) build.

	* Makefile.am: Add to EXTRA_DIST. Add rules to produce the
	corresponding non-*.in files.

	* gtype.h: (Win32:) Mark _g_type_fundamental_last for
	export/import from DLL.

Fri May  5 01:15:48 2000  Tim Janik  <timj@gtk.org>

	* gtype.h: add reserved fundamental ids for gtk types (for transition
	time). added G_TYPE_FUNDAMENTAL_MAX for gtk.

Mon Apr 17 20:45:50 2000  Tim Janik  <timj@gtk.org>

	* glib-gobject.c (g_object_base_class_finalize): oops, don't unset
	n_params prior to destructing them.

Tue Apr 11 04:28:10 2000  Tim Janik  <timj@gtk.org>

	* fixed a couple of bugs in the initial parameter/object
	implementations, after getting beast running on GObject and GValue.

Fri Apr  7 04:27:49 2000  Tim Janik  <timj@gtk.org>

	* glib-gobject.[hc]: completed parameter set/get implementations,
	along with asyncronous parameter changed notification queue.

Sun Apr  2 04:54:36 2000  Tim Janik  <timj@gtk.org>

	* glib-gobject.[hc]: GObject implementation, that is facilities
	for setting/getting quarked data and reference counting.

	* glib-gparamspecs.[hc]: first actuall parameter implementations
	for GLib, so far we have: char, uchar, bool, int, uint, long,
	ulong, enum, flags, float, double, string and object. each of these
	GParamSpecs is a new instantiatable type in its own respect,
	so the .c file derives 13 new types from G_TYPE_PARAM and
	defines over 50 (*2) conversion facilities.

	* glib-gvaluecollector.h: generic varargs handling stubs for
	GParamSpecs, private header file (does get installed for
	inclusion into user code though).

	* glib-gvalue.[hc]: GValue functionality implementation.

	* glib-gparam.[hc]: basis GParamSpec implementation for
	the virtual base type G_TYPE_PARAM.

        * glib-genums.[hc]: enum/flags type implementation, based on
	bseenum.[hc].

	* glib-gtype.[hc]: GLib Type System implementation, heavily
	based on BSE's dynamic type system.
