The way of getting the default value out of a GParamSpec is to allocate
a GValue, initialise it, then call g_param_spec_set_default() to set the
default value into that GValue.
This is exactly how we handle setting the default value for all of the
construct properties that were not explicitly passed to g_object_new().
Instead of doing the alloc/init/store on all construct properties on
every call to g_object_new(), we can cache those GValues in the private
data of the GParamSpec itself and reuse them.
This patch does not actually make that change to g_object_new() yet, but
it adds the API to GParamSpec so that a future patch to GObject can make
the change.

Either g_type_register_static_simple (used by G_DEFINE_TYPE_EXTENDED)
and G_IMPLEMENT_INTERFACE use automatic variables for GTypeInfo and
GInterfaceInfo structs, while tutorials and source code often use
static variables. This commit consistently adopts the former method.
https://bugzilla.gnome.org/show_bug.cgi?id=600161
All locks are now zero-initialised, so we can drop the G_*_INIT macros
for them.
Adjust various users around GLib accordingly and change the docs.
https://bugzilla.gnome.org/show_bug.cgi?id=659866
In an attempt to avoid some potential future abuses of the GParamSpec
API, qualify the 'name' field of the structure as 'const' and add a
comment noting that it is an interned string.
This is a theoretical API break, but it will only ever result in
warnings -- and even then, only if you were already doing something
questionable.
Clean up some of the warnings that were caused internally in gparam.c
from these changes.
g_object_class_list_properties tries to sort the returned list of
paramspecs by 'type depth' and param_id. But all the overridden
interface properties have a param_id of 0, so they come out in
a random order.

Bug 548689 – The type name for GParamSpec is wrong
* gparam.c (g_param_type_init):
Register the type name as GParam instead of GParamSpec.
svn path=/trunk/; revision=7374
2008-06-22 Michael Natterer <mitch@imendio.com>
* *.c: remove trailing whitespace from newly added gtk-doc
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
included before glib includes. Remove trailing whitespace from
SECTION comments and did some reformatting where lines were overly
long, no documentation content was changed.
svn path=/trunk/; revision=7089
Wed Nov 23 18:01:46 2005 Tim Janik <timj@imendio.com>
* gobject.[hc]: added floating reference count.
g_object_is_floating():
g_object_ref_sink(): new functions to deal with floating references.
g_object_force_floating(): new funciton for object implementations
to set the floating flag.
* gobject.c (g_object_init): make objects initially floating.
Wed Nov 23 17:58:13 2005 Tim Janik <timj@gtk.org>
* gparam.[hc]: added g_param_spec_ref_sink().
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.
2005-08-31 Matthias Clasen <mclasen@redhat.com>
* gparam.c (g_param_spec_internal): Intern the name here,
since we need the quark anyway when sending change notification.
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)
2005-03-25 Matthias Clasen <mclasen@redhat.com>

lookup if the name was already canonical. (#171502, Morten
Welinder)
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.
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
Tue Oct 14 17:40:19 2003 Owen Taylor <otaylor@redhat.com>
* gparamspecs.[ch]: Add a new GParamSpecOverride type
that is a pointer to a different paramspec in a parent
class or interface.
* gparam.[ch]: Add g_paramspec_get_redirect_target()
which follows GParamSpecOverride to the real property.
Make g_param_spec_pool_list() hand redirections,
properties on interfaces.
* gobject.[ch] gobjectnotifyqueue.c: Add
g_object_interface_install_property,
g_object_interface_find_property,
g_object_interface_list_properties(). Redirect virtually all
publically exposed GParamSpec's to the redirect target if
any. (->constructor is the exception.)
(#105894)
2003-09-12 Matthias Clasen <maclas@gmx.de>
Make the g_value_set_x_take_ownership() functions "official"
part of the API (#100948):
* gvaluetypes.[hc]: Add g_value_take_string() (synonym to the
now deprecated g_value_set_string_take_ownership()).
* gparam.[hc]: Add g_value_take_param() (synonym to the
now deprecated g_value_set_param_take_ownership()).
* gobject.[hc]: Add g_value_take_object() (synonym to the
now deprecated g_value_set_object_take_ownership()).
* gboxed.[hc]: Add g_value_take_boxed() (synonym to the
now deprecated g_value_set_boxed_take_ownership()).
* gobject/gobject-sections.txt: Add new g_value_take_x() functions.

functions. (#100948)
Tue Mar 19 18:57:12 2002 Tim Janik <timj@gtk.org>
* gtype.c (check_add_interface_L): applied patch from Matthias Clasen
<maclas@gmx.de> to check for prerequisite of interfaces, fixes#74427.
fixed mutex recursion in his patch (we can't call g_type_is_a() while
holding a read lock).
* gparam.c (canonalize_key): cleanup.
2002-03-13 Alexander Larsson <alla@lysator.liu.se>
* gparam.c (canonalize_key):
Function to canonicalize parameter names. Faster than
using g_strcanon().
(g_param_spec_internal, param_spec_ht_lookup):
Use canonalize_key.
Sun Feb 16 22:08:48 2002 Tim Janik <timj@gtk.org>
* gobject.[hc]:
* gparam.[hc]: provide marshaller specific value_set_*_take_ownership()
variants.
* gvalue.h: shrink GValue's data contents to 2 unions.
* glib-genmarshal.c: fix release and realeas_check hackage by always
using _take_ownership() variants. directly access value contents if
G_ENABLE_DEBUG is not defined.
* gobject.h: add padding pointers to the class struct.
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.
Tue Sep 18 22:57:33 2001 Tim Janik <timj@gtk.org>
* configure.in (GLIB_MICRO_VERSION): up version number to 1.3.8,
interface age 0, binary age 0.
* NEWS: updates.
Tue Sep 18 23:09:02 2001 Tim Janik <timj@gtk.org>
* gparam.[hc]: rename *nick and *blurb fields to catch
direct accesses in third party code.
provide g_param_get_nick(), g_param_get_blurb() and
g_param_get_name() accessors.
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 Jun 11 17:07:06 2001 Tim Janik <timj@gtk.org>
* gboxed.[hc]: remove left-over usages of an anonymous GBoxed typedef.
* gobjectnotifyqueue.c: moved property notify queue implementation
bits into this function.
* gparam.[hc]: added g_param_spec_pool_belongings(), completed
g_param_spec_pool_list(). added GParameter for _setv() functions.
* gobject.[hc]: use gobjectnotifyqueue.h implementation now.
got rid of properties_changed signal.
new functions g_object_newv(), g_object_class_list_properties().
removed "properties_changed" signal.
* gtype.[hc]: added g_type_depth() to figure number of parent
types + 1 for a type.
* gsignal.h: add g_signal_connect() (as per owen's request) and
g_signal_connect_swapped().
Tue Apr 3 13:46:22 2001 Tim Janik <timj@gtk.org>
* glist.[hc]: added g_list_nth_prev() which walks ->prev instead
of ->next.
* gpattern.[hc]: added shell-style pattern matching code from beast,
derived from the gtk_pattern_*() code, but with a couple of bug fixes
and a number of optimizations.
Tue Apr 3 14:06:00 2001 Tim Janik <timj@gtk.org>
* gparam.[hc]: added g_param_spec_pool_list() to list pspecs per
owner_type. the pspecs are not referenced, so the caller is
supposed to have some idea about owner_type not randomly
nuking his pspec's. if this is going to provide problems in
the future, we can either auto-ref the pspecs, or add a
_foreach variant, though the latter would have to invoke
the callback while pspec's mutex is acquired, so i just
went for the _list variant for now.
* gclosure.h (G_CALLBACK): made GCallback a void (*) (void) fucntion.
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.
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>.
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.
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.
Fri Dec 15 04:40:23 2000 Tim Janik <timj@gtk.org>
* gparam.[hc]: add an instance member value_type so the default
value of the pspec class can be overridden.
Tue Dec 12 18:58:22 2000 Tim Janik <timj@gtk.org>
* ghash.c (g_hash_table_remove): return whether a value
got removed.
Tue Dec 12 23:38:02 2000 Tim Janik <timj@gtk.org>
* Makefile.am: _never_ touch oldest-source-stamp.
* gobject.[hc]: construct property handling fixes/improvements.
fixed trailer handling in get/set property.
* gparam.[hc]: implement param spec pool, got rid of param spec
hashtable. the most prominent change is that e deal with type
prefixes here.
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_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.
2000-10-30 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gvalue.c (exchange_entries_equal), gparam.c (param_spec_equals):
made both functions return gboolean just for the little extra
standard conformance now that GEqualFunc is introduced.
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.

* 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.
Thu Jul 13 02:07:54 2000 Tim Janik <timj@gtk.org>
* gparam.c (g_param_value_defaults): default initialize the temporary
default value, instead of nuking the caller's value contents.
Fri Jun 23 17:20:26 2000 Tim Janik <timj@gtk.org>
* glib.h: define gstring in terms of gchar*. this typedef reflects
the type name of the primitive G_TYPE_STRING in the gobject module.
Sat Jun 24 23:03:04 2000 Tim Janik <timj@gtk.org>
* gtype.[hc]: provide G_TYPE_CHAR, G_TYPE_UCHAR, G_TYPE_BOOLEAN,
G_TYPE_INT, G_TYPE_UINT, G_TYPE_LONG, G_TYPE_ULONG, G_TYPE_FLOAT,
G_TYPE_DOUBLE and G_TYPE_STRING fundamental types.
added a GTypeValueTable* pointer to GTypeInfo structure for types
to implement GValue handling functions.
GTypeValueTable contains the following members:
value_init(): initialize a GValue structure.
value_free(): free GValue structure contents (optional).
value_copy(): copy one GValue contents to another GValue structure of
collect_type: varargs collection type for the first variable argument
to be collected by collect_value().
collect_value(): variable arguments collection function (optional).
lcopy_type: varargs collection type for the first variable argument
to be location copyied by lcopy_value().
lcopy_value(): variable arguments location copy function (optional).
g_type_value_table_peek(): new function to retrive the GTypeValueTable*
for a type node. ValueTables get inherited from parent types, unless
overridden through the GTypeInfo structure. internally, GTypeValueTable
support means an added overhead of one pointer per static or used
dynamic type node.
g_type_add_class_cache_func(): provide a cache_func/data pair to be
called prior to a type nodes last_unref() function, this can be used
to prevent premature class destruction. multiple installed cache_func()
will be chained upon last_unref() untill one of them returns TRUE.
the cache_func()s have to check the type id passed in to figure whether
they actually wants to cache the class of this type (since any types are
routed through the cache_func() chain).
g_type_remove_class_cache_func(): remove a previously installed
cache_func/data pair. the cache maintained by this function has to be
clear when calling g_type_remove_class_cache_func() to avoid leaks.
g_type_class_unref_uncached(): class unref function for cache_func()
implementations, unreferences a class omitting the cache chain (and
therefore unref->cache->unref->... loops).
* gvaluetypes.[hc]: provide the value setters/getters for the primitive
fundamental types boolean, char, uchar, int, uint, long, ulong, float,
double and string.
* gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a
GTypeValueTable is provided for this type.
removed g_value_init_default(), g_value_validate(), g_value_defaults(),
g_value_set_default() and g_values_cmp() as these are supplied by the
GParamSpec API now.
moved g_values_exchange() into the "implementation details" section,
since it just provides the underlying functionality for
g_value_convert().
* gvaluecollector.h: renamed the varargs value container from
GParamCValue to GTypeCValue as the value collection methods are
supplied by the type system now.
G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to
G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a
GParamSpec structure now.
* genums.h: macros cleanups/fixes.
* genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type
and assorted g_value_{s|g}et_{enum|flags}() implementations.
* gobject.[hc]:
provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods
and g_value_{s|g}et_object().
* gparam.[hc]: reduced class to value_set_default(),
value_validate() and values_cmp(). also parameters now need to fill
in a GType value_type; field to indicate the GValue type they
are handling. provide g_param_value_set_default(),
g_param_value_defaults(), g_param_value_validate() and
g_param_values_cmp().
* gparamspecs.[hc]: got rid of the g_value_* functions and
the G_IS_VALUE_* macros. adapted param spec implementations
according to the GParamSpecClass changes.
Fri May 5 01:15:48 2000 Tim Janik <timj@gtk.org>
* gtype.h: add reserved fundamental ids for gtk types (for transition
time). added G_TYPE_FUNDAMENTAL_MAX for gtk.
Mon Apr 17 20:45:50 2000 Tim Janik <timj@gtk.org>
* glib-gobject.c (g_object_base_class_finalize): oops, don't unset
n_params prior to destructing them.
Tue Apr 11 04:28:10 2000 Tim Janik <timj@gtk.org>
* fixed a couple of bugs in the initial parameter/object
implementations, after getting beast running on GObject and GValue.
Fri Apr 7 04:27:49 2000 Tim Janik <timj@gtk.org>
* glib-gobject.[hc]: completed parameter set/get implementations,
along with asyncronous parameter changed notification queue.
Sun Apr 2 04:54:36 2000 Tim Janik <timj@gtk.org>
* glib-gobject.[hc]: GObject implementation, that is facilities
for setting/getting quarked data and reference counting.
* glib-gparamspecs.[hc]: first actuall parameter implementations
for GLib, so far we have: char, uchar, bool, int, uint, long,
ulong, enum, flags, float, double, string and object. each of these
GParamSpecs is a new instantiatable type in its own respect,
so the .c file derives 13 new types from G_TYPE_PARAM and
defines over 50 (*2) conversion facilities.
* glib-gvaluecollector.h: generic varargs handling stubs for
GParamSpecs, private header file (does get installed for
inclusion into user code though).
* glib-gvalue.[hc]: GValue functionality implementation.
* glib-gparam.[hc]: basis GParamSpec implementation for
the virtual base type G_TYPE_PARAM.
* glib-genums.[hc]: enum/flags type implementation, based on
bseenum.[hc].
* glib-extra.[hc]: GLib additions, including 1.3 compatibility
routines and various other functions, from string manipulation
over list manipulation up to a unix signal GSource.
* glib-gtype.[hc]: GLib Type System implementation, heavily
based on BSE's dynamic type system.
