61b0e1c8d4 Add G_SIGNAL_MUST_COLLECT
In some cases, signal arguments have to be collected, even if there are i
no signal handlers connected (e.g. for GVariant parameters, where collection
consumes a floating variant).

Based on a patch by Christian Persch.

Bug #643624.

8e41be13ef Add dtrace and systemtap support for gobject
This adds static markers and systemtap tapsets for:

* type creation
* object lifetimes (creation, ref, unref, dispose, finalize)
* signal creation and emission

Signal emissions and finalization marker have a corresponding
*_end (or *-end in dtrace) version that is when the corresponding
operation is finished.

3d98c449b1 gsignal: improve g_signal_new docs.
Using 0 for class_offset is only a means to be able to add signal when running
out of slots in the lass structure.

914120b970 Ensure values are memset to 0 when calling G_VALUE_COLLECT_INIT()
The reason we need to enforce this is that the GTypeValueTable
documentation explicitly states that memory is memset to 0 when the
value_init function is called.

20d4f6da73 Bug 541208 – Functions to easily install and use signals without class
2008-07-04  Michael Natterer  <mitch@imendio.com>

	Bug 541208 – Functions to easily install and use signals without
	class struct slot

	* gobject.symbols
	* gsignal.[ch] (g_signal_new_class_handler): the same as
	_gtk_binding_signal_new(), to install signals with a callback
	instead of a class struct slot as class closure.

	The next two functions are C convenience and much easier to use
	than the generic overriding and chaining APIs which are intended
	primarily for language bindings:

	(g_signal_override_class_handler): to override a signal with a
	callback instead of a class struct slot.

	(g_signal_chain_from_overridden_handler): to chain up from a
	signal without class struct slot. The API is similar to
	g_signal_emit().

Tue Nov  1 16:24:20 2005  Tim Janik  <timj@imendio.com>

        * glib/gmem.[hc]: prepared deprecation of GMemChunk and GAllocator.
        added g_slice_*() API to allocate and cache small bits of memory.
        an actuall allocator implementation for g_slice_*() is still pending.

        * glib/gthread.[hc]: changes from a patch by Matthias Clasen.
        changed GRealThread list to use in-structure *next; fields instead
        of GSList, in order for thread iteration to not depenend on g_slice_*()
        indirectly.
        _g_thread_mem_private_get():
        _g_thread_mem_private_set(): added accessors for private memory,
        needed because the ordinary GPrivate implementation relies on GArray
        and GSList and therefore indirectly on working g_slice_*() allocations.

        * glib/gthread.[hc]:
        g_thread_foreach(): new public API function to loop over all existing threads.

        * glib/gdataset.c:
        * glib/gstring.c:
        * glib/gcache.c:

        * glib/gmain.c:
        * glib/gnode.c:
        removed GAllocator and free list usages and accompanying locks.
        use g_slice_*() API to allocate and cache small bits of memory.

        * glib/ghook.h: removed GMemChunk field from public API.

        * glib/gslist.h:
        * glib/glist.h: deprecate allocator API, provide _free1() for consistency.

        * glib/gnode.h: deprecate allocator API.

        * glib/gmain.c: reordered GPollRec fields so g_slice_free_chain() can
        be used for poll rec lists.

        * glib/grel.c: removed mem chunk usage, and allocated tuples via g_slice_*().
        g_relation_destroy(): free all tuples from the all_tuples hash table,
        this effectively maintains the life time track keeping of tuples.
        g_relation_delete_tuple(): free tuples which are removed from the
        all_tuples hash table. this fixes a temporary leak that was present
        in the memchunk code until the destruction of the relation.

        * gobject.c: reverted notify_mutex introduction, since this prevents

        modifications.

        destroying signal handlers.

	* gclosure.c (g_closure_ref, g_closure_unref): Use atomic

Tue Dec 18 21:39:57 2001  Tim Janik  <timj@gtk.org>

        * testoverride.c: added some assertions to test
        g_signal_get_invocation_hint().

        * gsignal.[hc]: remove signal_id argument from
        g_signal_chain_from_overridden(), the parameters are assumed to match
        the innermost signal currently in emission for this instance.
        added g_signal_get_invocation_hint() to figure the invocation hint
        of the innermost signal emission of an instance.

        * gsignal.c (g_signal_list_ids): fix G_BSEARCH_ARRAY_NODES() to
        access a bsearch array and not a pointer to it (discovered by
        Sven Neumann).

Mon Nov 26 09:55:12 2001  Tim Janik  <timj@gtk.org>

        * gtype.h: typedef GType to gulong instead of gsize, if possible.

        * gtype.c: fixups for GType being sizeof(long) wide (changed
        UINT casts).
        * gsignal.c:

Tue Nov 13 23:18:10 2001  Tim Janik  <timj@gtk.org>

        * gsignal.[hc]: add API for chaining:
        g_signal_chain_from_overridden() and g_signal_override_class_closure(),
        implementation yet to come.

        * gtype.[hc], Makefile.am: provide G_LOG_DOMAIN as compile flag.

        * gparam.[hc]: s/g_param_get/g_param_spec_get/ for get_nick,
        get_name and get_blurb, to be consistent with the rest of the
        g_param_spec_*() functions.

        * gparamspecs.[hc]: got rid of bogus GClosure paramspec.
        G_TYPE_CLOSURE is a boxed type already.

        * gobject/gsignal.c: (g_signal_emitv): ifdef variable used
        only if G_ENABLE_DEBUG to avoid gcc warning.
        * gobject/gtype.c: (type_iface_vtable_init_Wm),
        (type_iface_vtable_finalize_Wm): ifdef call needed only
        if !G_DISABLE_ASSERT to avoid gcc warning.
        * tests/testglib.c: (main): ifdef call needed only if
        !G_DISABLE_ASSERT to avoid gcc warning. Maybe later we
        should make the test to #undef G_DISABLE_ASSERT.
        * tests/unicode-collate.c: Add include of <string.h> to
        avoid gcc warning.

        * configure.in (GLIB_MICRO_VERSION): up version number to 1.3.7,
        interface age 0, binary age 0.

Thu Jun 28 16:42:49 2001  Tim Janik  <timj@gtk.org>

        * gsignal.c (g_signal_lookup):
        (g_signal_list_ids): give elaborate warnings about invalid types,
        non-instantiatable types and unloaded types that we can't operate on.

        * gparam.[hc]: g_param_spec_pool_belongings() ->
        g_param_spec_pool_list_owned().

        * gsignal.[hc]: renamed:
        g_signal_newc -> g_signal_new
        g_signal_disconnect_by_func -> g_signal_handlers_disconnect_by_func
        g_signal_block_by_func -> g_signal_handlers_block_by_func
        g_signal_unblock_by_func -> g_signal_handlers_unblock_by_func
        added GConnectType to simplify (..gboolean swapped, gboolean after)
        args.

        * gobject.[hc]: changed prototypes accordingly.

        * gmain.c (g_main_context_prepare): unlock context when bailing
        out with a warning.
        (g_main_context_check): same here.

        * gmain.c (g_main_context_check): before returning due to
        changed pollfds, unlock context.

Sun May 27 04:52:28 2001  Tim Janik  <timj@gtk.org>

        * gsignal.[hc] (g_signal_stop_emission_by_name): added variant
        to stop signal emissions through a detailed_signal string.

        * gsignal.c (signal_emit_R) (g_signal_emit_valist): account for
        the fact that g_value_* functions may cause signal emissons by
        unlocking the global signal system lock around g_value_* functions.
        (signal_emit_unlocked_R): renamed this from signal_emit_R() to reflect
        that this functions acquires the lock on its own now.

Sat Apr 28 23:39:42 2001  Tim Janik  <timj@gtk.org>

        * gsignal.[hc]: made signal handler and emission hook ids gulongs.
        (signal_handlers_foreach_matched_R): only invoke callback for handlers
        that are not disconnected (id>0).
        (signal_emit_R): prevent invocation of signal handlers during the
        emission they were connected within.

        * glib-mkenums: publically installed perl-script to parse C code
        enums and generate descriptions thereof.
        * glib-mkenums.1: assorted man page.

Sat Mar 31 23:55:58 2001  Tim Janik  <timj@gtk.org>

        * gtype.h:
        * gparamspecs.[hc]: applied patch from owen to implement
        GParamSpecUnichar.

Fri Mar 30 07:34:02 2001  Tim Janik  <timj@gtk.org>

        * gtype.c (type_iface_retrive_holder_info_Wm):
        * gtypeplugin.c (g_type_plugin_complete_interface_info):
        * gtypemodule.c (g_type_module_complete_interface_info):
        change order of instance_type and interface_type so they match
        the g_type_add_interface_*() API.

        * gsignal.c (g_signal_emit_valist): always assign C return value
        location, people depending on unaltered return values after emissions
        that had no handlers to run need to use g_signal_emitv().

        * gtype.[hc] (g_type_query): new function to allow querying of
        class and object size (semantics like g_signal_query()).
        currently the implementation is better held conservative so as to
        only support types that are classed and static.

Wed Mar 14 18:46:54 2001  Tim Janik  <timj@gtk.org>

        * gscanner.[hc]: removed archaic gpointer derived_data; relict and
        added a GData member instead.

        * glist.[hc]: added g_list_remove_all().

        * gslist.[hc]: added g_slist_remove_all().

Sat Mar 17 23:18:36 2001  Tim Janik  <timj@gtk.org>

        * gobject.c (g_object_get_property): minor bug-fix.

        * gbsearcharray.[hc]: provide a macro for static initialization and
        functions g_bsearch_array_new() and g_bsearch_array_destroy() for
        dynamic allocations.

        * gboxed.c: introduce G_TYPE_GSTRING, boxed type for GString.

        * gclosure.[hc]: naming corrections.

Fri Mar  9 16:42:08 2001  Tim Janik  <timj@gtk.org>

        * gvaluetypes.[hc]: moved g_strdup_value_contents() into this file as
        a public function (was static in gobject.c before). it's a bit odd
        to have that function here, especially since it requires extra includes,
        but then it doesn't very well fit somewhere else either.

        * gparamspecs.c: added default/max/min checks to param spec creation
        functions.

Fri Mar  9 14:57:17 2001  Tim Janik  <timj@gtk.org>

        * testgruntime.c: test program. covers run first/last/cleanup signal
        handlers, return value accumulator, signal string returns, and
        interface types in signal arguments.

        * gtype.c (g_type_value_table_peek): for interface types without
        value table, try looking up a value table from an instantiatable
        prerequisite type (this is safe as an interface may only have
        one instantiatable prerequisiste).
        (type_check_is_value_type_U): same here.

        * gsignal.c (g_signal_newv): assert that return types never have
        G_SIGNAL_TYPE_STATIC_SCOPE set.
        (g_signal_newc): only create class closure if the class_offset is not
        0.

617332234d destruction cleanup. there's one ->finalize_hook member in the hooklist
Thu Mar  8 16:23:34 2001  Tim Janik  <timj@gtk.org>

        * ghook.[hc]: destruction cleanup. there's one
        ->finalize_hook member in the hooklist now that gets
        called when a hook should be destroyed, that's it.
        that function is guarranteed to be called only when
        all ref_counts to the hook vanished, thus also when
        the hook is not in call.

Thu Mar  8 16:35:48 2001  Tim Janik  <timj@gtk.org>

        * gparamspecs.[hc]: s/g_param_spec_string_c/g_param_spec_stringc/.

        * gsignal.[hc]: fixed accumulator invocation, implemented emission
        hooks. and no, neither of these callbacks are called via a closure,
        language bindings can wrap the accumulator and emission hook
        interface, they already get parameters marshalled into a GValue array.
        (g_signal_connect): removed this function as its C specific, doesn't
        cover the swapped argument, is too close to its broken original
        gtk_signal_connect() and creates demand for _swapped, _after and
        _swapped_after variants <brrr>.
        (g_signal_connectc): convenience macro to connect a C handler
        func with data, like the old g_signal_connect() plus swapped
        argument.

        * gtype.h:
        * gboxed.c: added G_TYPE_VALUE boxed type.

Wed Mar  7 09:36:33 2001  Tim Janik  <timj@gtk.org>

	* gboxed.[hc]: changed prototype of g_boxed_type_register_static()
	to contain an optional init function and a hint at whether the
	boxed structure uses ref counting internally.
	added g_value_set_boxed_take_ownership().
	made G_TYPE_BOXED an abstract value type.

	* genums.[hc]: made G_TYPE_ENUM and G_TYPE_FLAGS abstract value
	types.

	* glib-genmarshal.c: argument type changes, preparation for third-party
	arg specification.

	* gobject.[hc]: cleaned up get/set property code.
	added g_strdup_value_contents() to improve warnings.

	* gparam.[hc]: added g_param_value_convert(), taking over responsibility
	of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so
	validation alterations may be valid a part of the property setting
	process.

	* gparamspecs.[hc]: made value comparisons stable (for sort applications).
	added GParamSpecValueArray, a param spec for value arrays and
	GParamSpecClosure. nuked the value exchange functions and
	GParamSpecCCallback.

	* gtype.[hc]: catch unintialized usages of the type system with
	g_return_val_if_uninitialized(). introduced G_TYPE_FLAG_VALUE_ABSTRACT
	to flag types that introduce a value table, but can't be used for
	g_value_init(). cleaned up reserved type ids.

	* gvalue.[hc]: code cleanups and saner checking.
	nuked the value exchange API. implemented value transformations, we
	can't really "convert" values, rather transforms are an anylogy to
	C casts, real conversions need a param spec for validation, which is
	why g_param_value_convert() does real conversions now.

	* gvaluearray.[hc]: new files that implement a GValueArray, a struct
	that can hold inhomogeneous arrays of value (to that extend that it
	also allowes undefined values, i.e. G_VALUE_TYPE(value)==0).
	this is exposed to the type system as a boxed type.

	* gvaluetransform.c: new file implementing most of the former value
	exchange functions as single-sided transformations.

	* gvaluetypes.[hc]: nuked G_TYPE_CCALLBACK, added
	g_value_set_string_take_ownership().

	* *.h: s/G_IS_VALUE_/G_VALUE_HOLDS_/.

	* *.[hc]: many fixes and cleanups.

	* many warning improvements.

Tue Feb 27 18:35:15 2001  Tim Janik  <timj@gtk.org>

	* gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS
	into G_VALUE_LCOPY(), this needs proper documenting.

	* gparam.c: fixed G_PARAM_USER_MASK.

	* gtype.c (type_data_make_W):
	(type_data_last_unref_Wm): fixed invalid memory freeing.

	* gobject.c (g_object_last_unref): destroy signal handlers associated
	with object, right before finalization.

	* gsignal.c (g_signal_parse_name): catch destroyed nodes or signals
	that don't actually support details.

	* gobject.[hc]: got rid of property trailers. nuked GObject
	properties "data" and the "signal" variants.
	(g_object_connect): new convenience function to do multiple
	signal connections at once.
	(g_object_disconnect): likewise, for disconnections.

	* gparam.[hc] (g_param_spec_pool_lookup): took out trailer support.

	* gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer()
	as private (the latter got renamed from g_value_get_as_pointer()).

Wed Mar  7 09:32:06 2001  Tim Janik  <timj@gtk.org>

        * glib-object.h: add gvaluearray.h.

        * gstring.[hc]: fixup naming of g_string_sprint*.

        * gtypes.h: fixed GCompareDataFunc naming.

Wed Mar  7 09:33:27 2001  Tim Janik  <timj@gtk.org>

Sat Feb 17 04:55:35 2001  Tim Janik  <timj@gtk.org>

        * gtype.[hc]: changed collect_format, collect_value() and lcopy_format,
        lcopy_value() in the GTypeValueTable. the collect functions are now
        called only once per value, collect_format/lcopy_format are strings
        that enlist all necessary GTypeCValues to be varargs-collected.

        * gvalue.h: ranamed STATIC_TAG to G_VALUE_NOCOPY_CONTENTS to indicate that
        a value shouldn't copy its contents.

        * gvaluecollector.h: changed G_VALUE_COLLECT() and G_VALUE_LCOPY()
        macros to carry an additional argument (flags) that can be used
        to pass G_VALUE_NOCOPY_CONTENTS along to the collection functions.

        * *.c: adapted collect_value() and lcopy_value() functions to the new
        prototypes, support G_VALUE_NOCOPY_CONTENTS where apropriate.

        * gsignal.[hc]: introduced a G_SIGNAL_TYPE_STATIC_SCOPE flag that can
        be passed along (ORed) with the parameter types, indicating that the
        emission arguments are to be considered static for the scope of the
        emission. should be used with care and only if the caller knows that
        a parameter cannot be destroyed/freed from signal handlers connected
        to an emission.

        * gobject/tmpl/types.sgml: incorporated huge docu patch from Eric
        Lemings <eric.b.lemings@lmco.com> with a bunch of editing on my part.

Fri Feb 16 07:10:44 2001  Tim Janik  <timj@gtk.org>

        * gclosure.c:
        (g_closure_ref):
        (g_closure_sink): make closure sinking explicit.

        * gsignal.c:
        (g_signal_connect_data):
        (g_signal_connect_closure):
        (g_signal_connect_closure_by_id):
        (g_signal_newv): perform explicit closure sinking.

Sun Feb  4 07:38:32 2001  Tim Janik  <timj@gtk.org>

        * docs/debugging.txt: s/glib_trap_/g_trap_/. add comments on
        g_trap_instance_signals, g_trace_instance_signals and
        GRUNTIME_DEBUG.

        * gmem.c: s/glib_trap_/g_trap_/.

Sun Feb  4 07:30:53 2001  Tim Janik  <timj@gtk.org>

        * gtype.[hc]: changed g_type_init() to take debugging flags
        initially, a combination of G_TYPE_DEBUG_OBJECTS and
        G_TYPE_DEBUG_SIGNALS. using the G_TYPE_ prefix is a bit odd
        here, but basically g_type_int() serves as initialization
        fucntion for all of GType, GObject, GSignal, so what the heck.

        * gobject.c: special case debugging code properly.
        changed glib_trap_object_ref to g_trap_object_ref.

        * gsignal.c: add signal emission debugging abilities, along with
        a new trap object g_trap_instance_signals.

Wed Jan 31 07:14:22 2001  Tim Janik  <timj@gtk.org>

        * gobject/Makefile.am: adapt to work with new CVS gtk-doc, leaving the old
        rules in place caused bogus recursions. main changes:
        - add to conditionalized section:
          all-local:
                $(MAKE) scan
                $(MAKE) templates
                $(MAKE) sgml
                $(MAKE) html.stamp
          html.stamp: sgml.stamp $(EXTRA_SGML_FILES)
                $(MAKE) html
          DOC_STAMPS= html.stamp sgml.stamp
        - change:
          maintainer-clean-local: clean
          -     cd $(srcdir) && rm -rf sgml html $(DOC_MODULE)-decl-list.txt $(DOC_MODULE)-decl.txt
          +     cd $(srcdir) && rm -rf sgml html $(DOC_MODULE)-decl-list.txt $(DOC_MODULE)-decl.txt $(DOC_STAMPS)

        * glib/Makefile.am (maintainer-clean-local): dito.

Wed Jan 31 06:21:32 2001  Tim Janik  <timj@gtk.org>

        * gobject/tmpl/types.sgml: applied docu patch from Eric Lemings
        <eric.b.lemings@lmco.com>, did some more editing.

Wed Jan 31 06:19:49 2001  Tim Janik  <timj@gtk.org>

        * gparam.h: gtk-doc sucks for not dealing with #define inside enums.

        * gtype.[hc]: added G_TYPE_FLAG_RESERVED_ID_BIT, a bit in the type
        number that's supposed to be left untouched (preserved mainly
        for the signal code).

        * *.c: added thread safety code, based on an old patch from sebastian.
        the remaining thread safety issues are now datalists on pspecs (to be
        solved im gdataset.c) and gvalue.c where locking concerns value exchange
        functionality only, and that's soon to be revised.

Thu Dec 28 10:21:46 2000  Tim Janik  <timj@gtk.org>

        * gmem.[hc]: got rid of outdated dmalloc support. provide g_try_malloc()
        and g_try_realloc() which _may_ fail and return NULL.
        nuked g_mem_check(), provided GMemVTable for memory function
        virtualization, alterable at program startup with g_mem_set_vtable().
        provided glib_mem_profiler_table and g_mem_profile() to support limited
        profiling information out of the box (uses mprotect() for free()ed areas
        on linux).
        provide globally visible G_MEM_ALIGN.
        buncha cleanups.

        * docs/macros.txt: file to get a clue about the various configuration
        macros.

        * docs/debugging.txt: explain debugging traps.

        * configure.in: got rid of --enable-mem-check and --enable-mem-profile,
        define GLIB_SIZEOF_VOID_P and GLIB_SIZEOF_LONG. check malloc prototypes
        and define SANE_MALLOC_PROTOS is we can use them.
        <boy, is this file a mess>

        * gutils.c, gscanner.c: fix up compatibility warnings, use g_message().


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).

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

	* gclosure.h: removed insane ramblings, added G_CALLBACK() a casting
	convenience macro.

	* Makefile.am: cleanups, marshaller generation rules.

	* gmarshal.[hc]: new files with GRuntime standard marshallers.

	* glib-genmarshal.c: fix log domain, support gruntime standard
	marshallers, suport G_TYPE_PARAM, come with extern "C" and
	#include gmarshal.h.

	* glib-genmarshal.1: reflect glib-genmarshal.c updates.

	* 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
	GParamSpecCCallback, param specs for G_TYPE_PARAM, G_TYPE_POINTER
	and G_TYPE_CCALLBACK respectively.

	* gsignal.[hc]: cleanups.
	(signal_id_lookup): after walking the anchestry, try interfaces as well.
	(g_signal_new): new function to create signals from varargs type list.
	(g_signal_connect_closure): closure connection variant that works from
	signal name+detail.
	(g_signal_connect_data): c handler connection variant that works from
	signal name+detail.
	(g_signal_emit_valist): emit signal for an instance with paraneters
	collected from a va_list.
	(g_signal_emit): emit signal, taking parameters from varargs list.
	(g_signal_emit_by_name): same as g_signal_emit, working from
	signal name+detail.
	(signal_emit_R): return whether return_value needs to be altered.

	* 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.

790a7bd3be Fix warnings.
* gmarkup.c: Fix warnings.

* guniprop.c, gunidecomp.c: Make warnings go away by using
GPOINTER_TO_INT() instead of (int).

* gcompletion.[ch]: Add g_completion_set_compare(),
to allow (for example) using case-insensitive completion.

* gobject/gsignal.c: Fix warnings about possible use of uninitialized
variables, and fix logic that would leave 'node' unset in cases
that it might be used in.

* gobject/glib-genmarshal.c: Fix warning about printf format.

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.

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.

        * 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).

Fri Nov  3 07:33:15 2000  Tim Janik  <timj@gtk.org>

        * gobject/gobject-docs.sgml: added &gobject-closures; section.

        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

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.

        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.
