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.

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().

Thu Sep 22 12:42:12 2005  Tim Janik  <timj@gtk.org>

        * gparam.c (g_param_spec_internal): fix pspec->name assignment which
        needs to be strdup()ed for non G_PARAM_STATIC_NAME pspecs. this fixes
        recently introduced crashes during plugin unloading.
        also, ensure that static pspec names are canonicalized.

        * gsignal.h: reverted last change from matthias, we don't guarantee
        that type ids aren't mangled with G_SIGNAL_TYPE_STATIC_SCOPE anywhere.

        * 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

5852eace66 Include gtypes.h not gobject/gtype.h
Sat Nov 17 14:10:35 2001  Owen Taylor  <otaylor@redhat.com>

	* glib/gbsearcharray.h: Include gtypes.h not gobject/gtype.h

	* glib/glib-object.h gobject/*.h: Prevent headers from
	being included directly except when compiling GObject.

	* gobject/gvaluecollector.h: Include glib-object.h so that
	this file can be included directly, since we don't
	include it _from_ glib-object.h.

	* gobject/gtype.c: Remove struct _GValue hack since we
	now include glib/gvaluecollector.h which simply pulls in
        glib-object.h.

        * 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.

        (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() ->

        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.

        (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.

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()).

bbc5a3adac changed collect_format, collect_value() and lcopy_format, lcopy_value() in
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.

	* 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.

83c45024e3 fixed a bag full of subtle bugs of immensive screw-up potential in
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.

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]:

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.

        * gmesage.c: print g_message() output to stderr instead of stdout.

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.
