* gobject/gsignal.c: g_type_default_interface_ref() was not
ensuring working g_signal_list_ids. Added checks for
!G_TYPE_IS_INTERFACE (itype).
(#465625, by some guy who calls himself Yeti)
svn path=/trunk/; revision=5704
2005-12-30 Matthias Clasen <mclasen@redhat.com>
* 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/gdataset.c:
* glib/gstring.c:
* glib/gcache.c:
* glib/garray.c:
* glib/gqueue.c:
* glib/gslist.c:
* glib/glist.c:
* glib/ghash.c:
* glib/gtree.c:
* glib/ghook.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.
2005-09-08 Kjartan Maraas <kmaraas@gnome.org>
* gclosure.c: (g_closure_set_meta_marshal): Remove some unused
code.
* gsignal.c: (g_signal_emitv): Same here
* gtype.c: (g_type_register_fundamental): And here
* testgobject.c: Mark some functions static.
2005-09-05 Matthias Clasen <mclasen@redhat.com>
* gsignal.c (struct _SignalNode): Make the name field const.
(g_signal_newv): Don't keep an unnecessary extra copy of the
signal name around, and don't forget to free the name if
an existing node is reused.
Sat Jul 30 21:10:26 2005 Tim Janik <timj@gtk.org>
* gobject.c: reverted notify_mutex introduction, since this prevents
parallelized setting of object properties on different objects, and
serves no apparent purpose (to me at least).
g_object_real_dispose(): removed non-atomic reference count
modifications.
g_object_unref(): make sure the closures array is destroyed when
destroying signal handlers.
* gparam.c: cosmetic changes.
* gsignal.c: comment fixup. allow 16bit blocking count.
* gsignal.c: reverted GClosure related changes.
* gclosure.c: reverted premature commit of atomic reference
counting attempt.
2005-07-15 Matthias Clasen <mclasen@redhat.com>
Make refcounting threadsafe by using atomic
operations. (#166020, Wim Taymans)
* gobject.c: Use a recursive lock to protect the
notify queue.
(g_object_unref): Get rid of g_object_last_unref and
do the last unref handling in g_object_unref.
(g_object_ref, g_object_unref): Use atomic operations.
* gsignal.c (struct _HandlerMatch): Use a full integer
for the ref_count field.
(handler_ref, handler_unref_R): Use atomic operations.
* gparam.c (g_param_spec_ref, g_param_spec_unref):
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.
* gsignal.c (handlers_find): Read the meta_marshal flag
of the closure atomically.
* tests/Makefile.am (SUBDIRS): Add tests/refcount
* configure.in: Add tests/refcount
* tests/refcount/properties.c: Test property changes
from multiple threads.
* tests/refcount/signals.c: Test signal emission from
multiple threads.
* tests/refcount/objects.c: Test refcounting from
multiple threads.
* tests/refcount/objects2.c:
* tests/refcount/properties2.c: Tests to measure the
overhead of threadsafe refcounting.
* glib/giochannel.c (g_io_channel_ref, g_io_channel_unref):
Use atomic operations to make refcounting
threadsafe. (#166020, Wim Taymans)
2005-03-14 Matthias Clasen <mclasen@redhat.com>
* abicheck.sh: Make work again.
* gsourceclosure.c: Fix a typo.
Make PLT-reduction work with gcc4, and don't include
everything in gobjectalias.h:
* gobject.symbols: Group symbols by header and source
file.
* makegobjectalias.pl: Protect definitions by the same
preprocessor symbols used to guard the headers. Move
the alias declarations to a separate file which is
produced when calling makegalias.pl -def
* Makefile.am (gobjectaliasdef.c): Add a rule to
build this file.
* *.c: Include gobjectalias.h after the other i
GLib headers, include gobjectaliasdef.c at the bottom.
Sun Nov 28 01:37:54 2004 <timj@birnet.org>
* gsignal.c: applied patch by sven@gimp.org (#153727) to reduce
signal connection complexity from O(n_handlers) to O(1).
2004-10-04 Matthias Clasen <mclasen@redhat.com>
* gsignal.c (g_signal_add_emission_hook): Improve the warning
if G_SIGNAL_NO_HOOKS is set. (#154299, Nickolay V. Shmyrev)
2004-09-16 Matthias Clasen <mclasen@redhat.com>
Implement the same PLT reduction technique used in GTK+:
* Makefile.am: Generate gobjectalias.h from gobject.symbols.
(BUILT_SOURCES): Add gobjectalias.h.
* makegobjectalias.pl: Script to generate gobjectalias.h.
* *.c: Include gobjectalias.h
Fri Sep 12 16:31:40 2003 Owen Taylor <otaylor@redhat.com>
* gsignal.[ch]: Add g_signal_accumulator_true_handled(), to
do TRUE-stops-emit signals.
* Makefile.am: Move testoverride.c and testifaceinit.c to
tests/gobject.
Tue Aug 19 04:08:14 2003 Tim Janik <timj@gtk.org>
* gvalue.c: adapt to new gbsearcharray.h code.
(g_value_register_transform_func): turn transform function
replacement into a valid operation.
* gsignal.c: adapt to new gbsearcharray.h code.
* gboxed.c: adapt to new gbsearcharray.h code.
Mon Nov 4 14:41:48 2002 Owen Taylor <otaylor@redhat.com>
* glib/gbsearcharray.c: Include config.h
so DISABLE_MEMPOOLS actually has an effect.
(#96437, Morten Welinder)
* tests/uri-test.c: Include <config.h>
Mon Nov 4 14:42:36 2002 Owen Taylor <otaylor@redhat.com>
* gtype.c gsignal.c gvaluearray.c: Include config.h
so DISABLE_MEMPOOLS actually has an effect.
(#96437, Morten Welinder)
* gsignal.c: Conditionalize definition of g_handler_ts
on DISABLE_MEM_POOLS (#96437)
Mon Nov 4 14:45:24 2002 Owen Taylor <otaylor@redhat.com>
* gthread-posix.c gthread-solaris.c: Include <config.h>
Mon May 20 15:57:47 2002 Owen Taylor <otaylor@redhat.com>
* gsignal.c: When printing errors, handle NULL
returns from g_type_debug(). (#73559, Laszlo Peter)
* gtype.c (type_descriptive_name_I): De-inline,
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>
* gobject.c gsignal.c: Change C++ comments for FIXME's to
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>
* 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.
Thu Feb 8 00:31:45 2001 Tim Janik <timj@gtk.org>
* gtype.h: added G_TYPE_DEBUG_NONE for/from Eric Lemings ;)
