glib/gobject/ChangeLog

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
	by havoc.

	* gsignal.c (g_signal_newv): fixed deadlock scenarion where
	g_signal_lookup() would be called with the signal lock being
	held. reported by james henstridge.

	* gclosure.c (g_closure_set_meta_marshal): fixed memcpy/overwrite bug
	reported by owen.

2000-10-26  Tor Lillqvist  <tml@iki.fi>

	* gbsearcharray.c (bsearch_array_insert): Fix gccisms (pointer
	arithmetic on void pointer, label without statement following.

	* gtype.c (type_node_fundamental_info): Don't apply unary minus to
	result of sizeof operator, it can be unsigned. Cast first to
	gssize.

	* gobject.def: Add new functions.

	* 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.

	* gobject.def: Export g_type_fundamental_last (the function).

2000-07-26  Tor Lillqvist  <tml@iki.fi>

	* gobject.def
	* gobject.c: Mark glib_debug_objects for export/import as it is
	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.
