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.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=606044
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.
https://bugzilla.gnome.org/show_bug.cgi?id=603590
Makes g_signal_emit_valist from 15% to 20% faster.
Results reported from profiling the pan newsreader which uses a variant
of simple and complex signal emissions (i.e no args or various args)

* gsignal.c (signal_lookup_closure): when defaulting to the only
item in the array, check if this is indeed the default closure.
(patch by Tim Janik).

Reviewed by Tim Janik:
* gsignal.c (g_signal_chain_from_overridden_handler): allocate
the temp GValue array with GSLice.
(g_signal_emit_valist): dito. Remove optimization/obfuscation of
allocating up to 16 GValues on the stack and always use GSLice.

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().

comments and reformatted some where they contained overly long or
ill-formatted lines.
svn path=/trunk/; revision=7090
2008-06-22 Michael Natterer <mitch@imendio.com>
* *.c: moved includes back to the top of the files (before gtk-doc
SECTION comments). Add "config.h" in all files and move system

* gsignal.c: Remove the handler trash stack, which
is now unused.
(g_signal_init): Remove the restriction that HandlerMatch
must be the same size as GList, and obsolete comments
referring to mem chunks.
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/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.

Use atomic operations instead of a lock to make the
refcounting threadsafe.
* gclosure.c (g_closure_ref, g_closure_unref): Use atomic
operations. This is more complicated here, since the
refcount is stored in a bitfield, so we also have
to access all other bitfield members atomically.

since it's only used for debugging.
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).
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.
* .cvsignore: Add some generated files.
* glib/gmain.c: (g_main_context_iterate): Comment out cruft
after #endif to avoid gcc warning.
* gmodule/gmodule.c: (g_module_set_error_unduped): Remove
const from type to avoid gcc warning.
* 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.
Thu Jun 28 16:57:44 2001 Tim Janik <timj@gtk.org>
* 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.
Mon May 28 06:51:24 2001 Tim Janik <timj@gtk.org>
* gsignal.c (signal_emit_unlocked_R): fixed bad faux-pass, forgot
to release signal lock when restarting emissions.
Sun May 27 05:09:18 2001 Tim Janik <timj@gtk.org>
* 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.
Mon May 14 01:49:01 2001 Tim Janik <timj@gtk.org>
* gsignal.[hc] (g_signal_handler_is_connected): new function
to check whether a handler is still connected to an instance
(by handler id).
Sun Apr 29 00:37:34 2001 Tim Janik <timj@gtk.org>
* ghook.[hc]: made hook ids a gulong.
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.
Wed Apr 18 09:46:56 2001 Owen Taylor <otaylor@redhat.com>

C comments. (Patch from Andres Salomon)
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.
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>
* gobject/Makefile.am: shuffled rules to avoid excessive
rebuilds.
* gobject/gobject-sections.txt: updates.
* gobject/tmpl/*: bunch of updates, added another patch
from Eric Lemings <eric.b.lemings@lmco.com>.
Wed Feb 21 18:31:46 2001 Jonathan Blandford <jrb@redhat.com>
* gsignal.h (g_signal_connect): Add g_signal_connect define to
make porting from gtk_signal_connect easy.
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.
Fri Feb 16 06:52:20 2001 Tim Janik <timj@gtk.org>
* 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>

* gtype.h: added G_TYPE_DEBUG_NONE for/from Eric Lemings ;)
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).
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
Mon Dec 11 04:44:11 2000 Tim Janik <timj@gtk.org>
* 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.
Wed Nov 29 13:30:05 2000 Tim Janik <timj@gtk.org>
* gsignal.c (handlers_find): fix elliots "logic fix" that dereferences
NULL nodes if C handlers are searched for specific signals.
* 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.
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).
Fri Nov 3 07:33:15 2000 Tim Janik <timj@gtk.org>
* gobject/gobject-docs.sgml: added &gobject-closures; section.
* gobject/Makefile.am (tmpl_sources): add tmpl/clsoures.sgml
* gobject/gobject-sections.txt: added Closure section.
* gobject/tmpl/closures.sgml: new file with template description
for GClosure functions.
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.
Mon Oct 30 06:01:43 2000 Tim Janik <timj@gtk.org>
* gobject/gobject-sections.txt: opened up a new section on signals.
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).
Sun Oct 29 02:31:03 2000 Owen Taylor <otaylor@redhat.com>
* gsignal.c (g_type_signals): Fix problem where signals
with "_" in them appeared twice in the result array.
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>
* 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.
Tue Oct 24 22:09:14 2000 Tim Janik <timj@gtk.org>
* glib-object.h: added newly added gobject/ headers.
* 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.
