Mon Aug 27 14:55:27 2001  Owen Taylor  <otaylor@redhat.com>

        * gsourceclosure.[ch] (g_source_set_closure): Implement.

        * gsourceclosure.[ch]: Add GType's for GIOChannel, GIOCondition.

2001-08-17  James Henstridge  <james@daa.com.au>

        * gobject.c (WeakRefStack): add an object member to the structure.
        (weak_refs_notify): pass wstack->object as extra argument to
        notify functions.
        (g_object_weak_ref): set wstack->object when initialising
        WeakRefStack.

        * gobject.h (GWeakNotify): add second argument to prototype which
        gives the pointer to where the object that is being disposed of
        was.

Wed Jul 18 19:42:31 2001  Tim Janik  <timj@gtk.org>

        * gtype.h: if __GNUC__ is defined, inline a test for an exact type
        match for instances and classes in G_TYPE_CHECK_INSTANCE_TYPE() and
        G_TYPE_CHECK_CLASS_TYPE() before calling g_type_instance_is_a().

Sun Aug 12 02:07:10 2001  Tim Janik  <timj@gtk.org>

        * gvaluearray.[hc]: fix preallocation logic, support DISABLE_MEM_POOLS
        properly, group value allocations.
        (g_value_array_new): fix semantic of n_prealloced argument, so it's
        really just about preallocation space.

2001-07-23  Padraig O'Briain <Padraig.Obriain@Sun.COM>
        
        * gobject/gobjectnotifyqueue.c: fix unconditional check of
        first GParamSpec in g_object_notify_queue_thaw(); to prevent
        property notification being lost.

2001-08-06  Sven Neumann  <sven@gimp.org>

        * gobject.[ch]: 
        added new functions g_object_[add|remove]_weak_pointer().

2001-08-01  Sven Neumann  <sven@gimp.org>

        * gsignal.h: added convenience macro g_signal_connect_after().

2001-07-29  Hans Breuer  <hans@breuer.org>

        * gobject.def : updated externals

2001-07-20  Hans Breuer  <hans@breuer.org>

        * gobject.def : updated externals

        * makefile.msc.in : reflect glib move

Tue Jul 10 18:50:16 2001  Tim Janik  <timj@gtk.org>

        * gsignal.h (struct _GSignalQuery): fix misplaced comment.

Mon Jul  2 07:17:47 2001  Tim Janik  <timj@gtk.org>

        * gobject.c (g_object_weak_ref): 
        (g_object_watch_closure): congrats tim, introducing of-by-one
        errors like on my very first day of C programming.

Sat Jun 30 11:07:00 2001  Tim Janik  <timj@gtk.org>

        * gobject.[hc]: provide weak_ref/weak_unref functions,
        invoked from ->dispose. renamed ->shutdown() to ->dispose(),
        provide "public" API entry here: g_object_run_dispose(), this
        fucntion should _only_ be called from object system implementations
        (e.g. gtkobject.c) if at all.

        * gtypemodule.c (g_type_module_dispose): s/shutdown/dispose/

        * gsignal.h: removed compat aliases.

        * gobject.c (g_object_connect): support data objects.
        
Sat Jun 30 13:17:12 2001  Owen Taylor  <otaylor@redhat.com>

        * testgruntime.c (test_object_class_init)
          gobject.c (g_object_do_class_init): 
          g_signal_newc() => g_signal_new().

Thu Jun 28 22:49:40 2001  Owen Taylor  <otaylor@redhat.com>

        * gtype.[ch] gobject-query.c testgruntime.c: Remove
        debug flag argument to g_type_init() and add
        g_type_init_with_debug_flags().

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.

2001-06-22  Hans Breuer  <hans@breuer.org>

        * gobject.def : updated externals

        * gobjectnotifyqueue.c : include <string.h> for memset ()

Thu Jun 21 02:43:10 2001  Tim Janik  <timj@gtk.org>

        * gparamspecs.h: s/long/int/ for default_value in enum and flags
        pspecs.

Wed Jun 20 03:59:42 2001  Tim Janik  <timj@gtk.org>

        * gtype.[hc]: added debugging variants g_type_name_from_class(),
        g_type_name_from_instance().

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().

2001-06-13  Havoc Pennington  <hp@redhat.com>

        * Makefile.am (progs_LDADD): link to ./libgobject-1.3.la
        since an installed libgobject was somehow being found; think 
        it's a libtool bug, but this workaround should do for now.

2001-06-12  Havoc Pennington  <hp@redhat.com>

        * Makefile.am (glib-mkenums): don't put $(srcdir)/glib-mkenums in
        bin_SCRIPTS, that breaks make install. Instead put 'glib-mkenums'
        in bin_SCRIPTS and cp it into builddir

Thu May 31 17:56:47 2001  Owen Taylor  <otaylor@redhat.com>

        * gobject-query.c: Fix mispelling in help output.
        (#53952, Skip Montanaro)

2001-05-28  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

        * Makefile.am (EXTRA_DIST): Really distribute glib-mkenums, now
        that bin_SCRIPTS doesn't seem to care about doing so anymore.

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 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.

2001-05-24  Hans Breuer  <hans@breuer.org>

        * makefile.msc.in : changed depndencies to build glib-genmarshal
        first and statically linked with glib, which makes it independent
        from the installed glib version. Added new object files to build.

        * gobject.def : updated

Thu May 24 08:52:02 2001  Owen Taylor  <otaylor@redhat.com>

        * gobject.[ch] (g_value_set_object): gpointer, not
        gpointer *.

2001-05-22  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

        * Makefile.am (bin_SCRIPTS): made 'make distcheck' happy.

        * gobject.def: Removed g_param_spec_stringc.

Tue May 22 02:46:13 2001  Tim Janik  <timj@gtk.org>

        * gobject.c (g_value_set_object): make g_value_set_object()
        take a gpointer v_object so people don't need to G_OBJECT()
        cast NULL pointers (C code convenience).

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).

Thu May 10 14:00:48 2001  Tim Janik  <timj@gtk.org>

        * gparamspecs.[hc]: removed g_param_spec_stringc() in lack of
        evidence of public need.

        * gsignal.h: added g_signal_disconnect_by_func(),
        g_signal_block_by_func() and g_signal_unblock_by_func() convenience
        macros as per owen's request.

        * gtype.c (SIZEOF_FUNDAMENTAL_INFO): align sizeof (GTypeFundamentalInfo)
        to size of longs and pointers.

2001-05-05  James Henstridge  <james@daa.com.au>

        * Makefile.am: glib-mkenums is not a compiled program, so shouldn't
        be in the bin_PROGRAMS primary.  Put it in bin_SCRIPTS instead, and
        removed the glib_mkenums_SOURCES var.

Thu May  3 06:10:23 2001  Owen Taylor  <otaylor@redhat.com>

        * gobject.c (g_object_set_[q]data_full): Make types of ternary
        operator correspond. (Fixes compilation errors with Sun CC,
        #52230)

Mon Apr 30 20:03:56 2001  Tim Janik  <timj@gtk.org>

        * glib-mkenums (usage): removed \v escaping, newer perl versions don't
        support this, and it'S probably useless anyways.

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.
        
2001-04-19  Havoc Pennington  <hp@redhat.com>

        * gobject.c (g_object_get_valist): We were returning junk memory
        here, because we didn't copy the value (G_VALUE_NOCOPY_CONTENTS
        passed to G_VALUE_LCOPY) and then we freed the GValue immediately
        after. Removed G_VALUE_NOCOPY_CONTENTS from here; need a
        G_VALUE_STEAL_CONTENTS or the like if we want this optimization.

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)

2001-04-14  Hans Breuer  <hans@breuer.org>

        * gobject.def : updated

Mon Apr  9 18:56:15 2001  Tim Janik  <timj@gtk.org>

        * gclosure.c (g_closure_invoke): only require marshal/meta_marshal if
        we're valid (about to actually do marshalling).

Tue Apr  3 20:23:24 2001  Tim Janik  <timj@gtk.org>

        * NEWS: updates.

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.

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.

2001-03-29  Tor Lillqvist  <tml@iki.fi>

        * gobject.def: Updates.

Wed Mar 28 17:04:06 2001  Tim Janik  <timj@gtk.org>

        * gobject.c (object_queue_property): only queue readable properties
        for notification changes.

Thu Mar 22 13:36:50 2001  Tim Janik  <timj@gtk.org>

        * gsignal.c (g_signal_newv): catch G_SIGNAL_RUN_FIRST with a return value.

2001-03-21  Martin Baulig  <baulig@suse.de>

        * gboxed.[ch] (g_value_dup_boxed): This takes a `const GValue *'
        argument.

2001-03-18  Tor Lillqvist  <tml@iki.fi>

        * gobject.def: Correct some renamed functions.

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.

2001-03-10  Tor Lillqvist  <tml@iki.fi>

        * gobject.def: Add a couple of missing entries.

        * Makefile.am (libgobject_1_3_la_LIBADD): Use only on Win32.

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.

Fri Mar  9 10:14:00 2001  Tim Janik  <timj@gtk.org>

        * gparamspecs.c (g_param_spec_object): use g_type_is_a() to check
        for object_type being a G_TYPE_OBJECT, not G_TYPE_IS_OBJECT(), since
        that wouldn't allow interface types.

        * gtype.c (g_type_interface_add_prerequisite): arg, fixed small cnp bug
        with bad implications and an off-by-one error.

Thu Mar  8 16:34:22 2001  Owen Taylor  <otaylor@redhat.com>

        * gvaluetransform.c: Include <string.h> for memcpy.

        * gvaluetransform.c (DEFINE_SPRINTF): Remove unnecessary
        and ANSI-illegal ## token pasting.

Thu Mar  8 18:11:52 2001  Tim Janik  <timj@gtk.org>

        * gsignal.c: eek, fixed old hook detail storage code.

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 19:02:51 2001  Tim Janik  <timj@gtk.org>

        * gtype.c (type_node_add_iface_entry_W): catch when adding an interface
        to an ancestor of a child that already conforms to this interface.
        currently we spew a warning here, should we be silent?
        (g_type_interface_add_prerequisite): new function to add a prerequisite
        type to an interface, that must succeed an instance is_a prerequisite
        type check before the interface can be added to an instance. the
        prerequisite types are also suuported in is_a checks of the interface.
        (g_type_instance_is_a):
        (g_type_check_instance_cast):
        (g_type_check_instance): cleanups and optimizations.
        (g_type_class_is_a):
        (g_type_check_class_cast): same, also prevented these from accepting
        interface types, as class structures don't nest interfaces.

2001-03-07  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

        * Makefile.am: Avoid rebuilding everything everytime.

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()).

2001-02-21  Tor Lillqvist  <tml@iki.fi>

        * *.h: Use G_BEGIN_DECLS and G_END_DECLS.

        * Makefile.am: Use libglib-1.3.la from top_builddir. Invoke
        libtool with -no-undefined for Win32 and Cygwin.

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.

        * gsignal.c (g_signal_emit_valist): Use G_TYPE_FROM_INSTANCE
        (instance) instead of node->itype when initting the value.

2001-02-17  Havoc Pennington  <hp@pobox.com>

        Applied patch from Soeren Sandmann:
        
        * gvaluetypes.c (g_value_get_string): G_CONST_RETURN

        * gtype.c (g_type_name): G_CONST_RETURN

        * gsignal.c (g_signal_name): G_CONST_RETURN

        * gobject-query.c (main): const fix

Sat Feb 17 07:58:46 2001  Tim Janik  <timj@gtk.org>

        * genums.h (G_TYPE_IS_FLAGS): patch from sven to fixup
        G_ENUM_CLASS_TYPE() macro.

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 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 ;)

2001-02-04  Tor Lillqvist  <tml@iki.fi>

        * gobject.def: Remove glib_debug_objects.

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.

2001-02-04  Tor Lillqvist  <tml@iki.fi>

        * Makefile.am (progs_LDADD): Change order of libs to libgobject
        first, then libglib. Needed for cygwin, says jbdoll@kepri.re.kr.

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.

2001-01-27  Tor Lillqvist  <tml@iki.fi>

        * makefile.msc.in: Don't try to compile gmarshal.c on its own.

2001-01-24    <alexl@redhat.com>

        * gclosure.c (g_closure_unref):
        Don't leak closure->notifiers.

2001-01-05  Havoc Pennington  <hp@redhat.com>

        * gparamspecs.c (g_param_spec_enum): set the value_type in the
        param spec; closes bug 40210
        (g_param_spec_flags): ditto for flags

2001-01-03  Alexander Larsson  <alexl@redhat.com>

        * gobject.c:
        Move glib_debug_objects out of the G_ENABLE_DEBUG #ifdef.

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  Tor Lillqvist  <tml@iki.fi>

        * gobject.def: Update.

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

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.

2000-12-14  Tor Lillqvist  <tml@iki.fi>

        * makefile.mingw.in: Update, include parts from Makefile.am to
        build gmarshal.[ch]. Some day, we won't need these separate
        makefiles for Win32 compilation. I hope.

        * makefile.msc.in: Update. No use trying to build gmarshal.[ch]
        here, it would require Unixish tools. MSVC users building from CVS
        sources are out of luck.
        
        * gobject.def: Update.

Wed Dec 13 09:31:26 2000  Tim Janik  <timj@gtk.org>

        * gparamspecs.[hc]: add G_TYPE_PARAM_BOXED implementation.

        * gobject.[hc]: minor fixes.

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.
        
2000-12-12  Elliot Lee  <sopwith@redhat.com>

        * Makefile.am:
          . You have to 'touch oldest-source-stamp' if you want to avoid having
          the Makefile constantly rebuild itself.
          . Fix marshaller generation rules to work with srcdir != builddir
            (there were issues with trying to run "./glib-genmarshal", etc.)

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.

2000-11-28  Elliot Lee  <sopwith@redhat.com>

        * 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.

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

2000-11-28  Tor Lillqvist  <tml@iki.fi>

        * gboxed.c: Include <string.h> for memset ().

2000-11-22  Tor Lillqvist  <tml@iki.fi>

        * gobject.def: Update.

2000-11-20  Havoc Pennington  <hp@redhat.com>

        * gobject.c (g_object_get_data)
        (g_object_set_data)
        (g_object_set_data_full)
        (g_object_steal_data): More convenient data-setting functions

Wed Nov 15 20:58:05 2000  Owen Taylor  <otaylor@redhat.com>

        * gtypemodule.c (g_type_module_use): If loading the
        module fails, don't increment the use count.

Thu Nov  9 01:49:43 2000  Tim Janik  <timj@gtk.org>

        * gobject.h (G_WARN_INVALID_PARAM_ID): doh,
        s/BSE_OBJECT_TYPE_NAME/G_OBJECT_TYPE_NAME/; reported by Maas-Maarten
        Zeeman <maas@wanadoo.nl>.

Mon Nov 13 00:48:39 2000  Owen Taylor  <otaylor@redhat.com>

        * Makefile.am (EXTRA_DIST): Add glib-genmarshal.1

2000-11-11  Tor Lillqvist  <tml@iki.fi>

        * gtypemodule.c: Include stdlib.h for exit().

        * makefile.{mingw,msc}.in (gobject_OBJECTS): Add gtypemodule.

        * gobject.def: Add missing functions.

Sun Nov  5 13:21:28 2000  Owen Taylor  <otaylor@redhat.com>

        * Makefile.am gtypemodule.[ch]: New basic implementation of
        GTypePlugin interface as a GObject. Dynamically loaded modules can
        register any number of types and interface on the module.

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.

2000-11-05  Tor Lillqvist  <tml@iki.fi>

        * makefile.{mingw,msc}.in (gobject_OBJECTS): Add gtypeplugin.

        * gobject.def: Update.

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).

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.

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.

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).

Mon Oct 30 03:00:07 2000  Tim Janik  <timj@gtk.org>

        * gsignal.[hc] (g_signal_list_ids): renamed owen's g_type_signals(),
        added required mutex locks.

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.

Sun Oct 29 01:58:44 2000  Owen Taylor  <otaylor@redhat.com>

        * gsignal.h: Add g_type_signals() - a function to list
        all signals for a given type.

Sat Oct 28 00:28:09 2000  Tim Janik  <timj@gtk.org>

        * gclosure.c (g_closure_add_marshal_guards): fixed notifier position
        for post_marshal guard which was off at 0.

Fri Oct 27 21:49:31 2000  Tim Janik  <timj@gtk.org>

        * gobject.[hc]: doh, fix argument order in for
        g_cclosure_new_object_swap and g_cclosure_new_object.

2000-10-28  Tor Lillqvist  <tml@iki.fi>

        * makefile.{mingw,msc}.in: Make glib-genmarshal.exe.

        * glib-genmarshal.c: Conditionalise include of unistd.h.
        Include <io.h> on Win32.

        * gobject.def: Add some missing entry points.

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>

        * gobject.c (g_object_watch_closure): fixed realloc bug, reported
        by havoc.

        * 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.

2000-10-26  Tor Lillqvist  <tml@iki.fi>

        * gbsearcharray.c (bsearch_array_insert): Fix gccisms (pointer
        arithmetic on void pointer, label without statement following.

        * gtype.c (type_node_fundamental_info): Don't apply unary minus to
        result of sizeof operator, it can be unsigned. Cast first to
        gssize.

        * gobject.def: Add new functions.

        * makefile.{mingw,msc}.in: Add new objects.

2000-10-26  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

        * Makefile.am: Remove empty SUBDIRS line _again_, as that _still_
        prevents 'make dist' from working.

Wed Oct 25 19:11:03 2000  Owen Taylor  <otaylor@redhat.com>

        * gbsearcharray.h (g_bsearch_array_get_nth): Don't use implicit
        casts from void * since this will get included from C++ too
        at times.
        
Thu Oct 26 00:30:27 2000  Tim Janik  <timj@gtk.org>

        * gvaluetypes.[hc]: added g_value_set_static_string().

        * gboxed.[hc]: const corrections. added g_value_set_static_boxed().

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.

2000-10-15  Raja R Harinath  <harinath@cs.umn.edu>

        * Makefile.am (BUILT_EXTRA_DIST): New variable.
        (dist-hook): Handle $(BUILT_EXTRA_DIST).
        (*): Remove traces of @STRIP_{BEGIN,END}@.
        
2000-09-29  Martin Baulig  <baulig@suse.de>
        
        Several minor ANSI C fixes.

        Added missing casts:
        * gtype.c (type_class_init): 
        `(gpointer) bnode->data->class.class_init_base'
        in call to g_slist_prepend() and
        'GBaseInitFunc class_init_base = (GBaseInitFunc) slist->data'.

        * gobject.c: Put text following #endif into comments.

2000-09-25  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

        * Makefile.am: Remove empty SUBDIRS line, as that prevents make
        dist from working.

Sat Sep  9 20:04:13 2000  Owen Taylor  <otaylor@redhat.com>

        * gobject.c (g_object_last_unref): Move call to
        g_type_free_instance() here from g_object_do_finalize,
        since g_type_free_instance() can unload the object's
        implementation.

2000-07-27  Tor Lillqvist  <tml@iki.fi>

        * gobject.c: No, don't mark glib_debug_objects for export here,
        it's handled specially in gtktypeutils.c.

        * gobject.def: Export g_type_fundamental_last (the function).

2000-07-26  Tor Lillqvist  <tml@iki.fi>

        * gobject.def
        * gobject.c: Mark glib_debug_objects for export/import as it is
        used by GTK+.

Sun Jul 23 17:23:35 2000  Tim Janik  <timj@gtk.org>

        * gtype.[hc]: make g_type_fundamental_last() a function, avoiding all
        that extern variable clutter and avoiding further problems with thread
        safety.

2000-07-19  Tor Lillqvist  <tml@iki.fi>

        * gparam.h
        * gvalue.h
        * gparam.c
        * gtype.c: Shut up Sun's picky compiler.

2000-07-14  Tor Lillqvist  <tml@iki.fi>

        * gobject.def: Add g_type_get_plugin.

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.

2000-07-11  Raja R Harinath  <harinath@cs.umn.edu>

        * gtype.c (g_type_get_plugin): Don't return just 0 or 1.

Tue Jul 11 02:48:13 2000  Tim Janik  <timj@gtk.org>

        * gtype.[hc]: removed g_type_is_dynamic() and added g_type_get_plugin().

2000-07-10  Tor Lillqvist  <tml@iki.fi>

        * gobject-query.c: Include ../config.h for HAVE_UNISTD_H. Use it
        to guard inclusion of <unistd.h>.

        * gtype.h: Fix copy-paste errors in the ifdefs on how to declare a
        variable for export. Call the macro GOBJECT_VAR.

        * gtype.c: Declare _g_type_fundamental_last for export here, too.
        (type_node_any_new): Use only constant expressions for sizeof
        operator (for instance MSVC requires this).

        * makefile.mingw.in: Define GOBJECT_COMPILATION.

Sun Jul  9 21:21:46 2000  Owen Taylor  <otaylor@redhat.com>

        * genums.c: Move string.h include into the .c file
        instead of where it was in the .h file by mistake.

Thu Jul  6 15:30:27 2000  Owen Taylor  <otaylor@redhat.com>

        * Makefile.am (EXTRA_DIST): dist fixes.

        * gobject.c: Add a global variable glib_debug_objects
        (not in header file) to control object tracing.

2000-07-01  Tor Lillqvist  <tml@iki.fi>

        * gobject.def: Update added and renamed entry points.

        * makefile.mingw.in: Add gvaluetypes.o.

Thu Jun 29 16:02:07 2000  Owen Taylor  <otaylor@redhat.com>

        * gobject.c:include string.h for memset
        * genums.h: include string.h for strcpy
        * gvalue.c: include string.h for memset, memcpy.

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 class id passed in to figure whether
        they actually want to cache the class of this type (since all classes
        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.

Sat Jun 10 08:38:27 2000  Tim Janik  <timj@gtk.org>

        * gtype.c (type_class_init): fetch the nth iface entry of the
        type node in the nth loop iteration, not alwys the first.
        bug discovered by Walt Pohl <cher@suitware.com>.
        (type_data_finalize_class_ifaces): same here, cut and paste
        rulez.

Wed Jun  7 09:21:05 2000  Owen Taylor  <otaylor@redhat.com>

        * Makefile.am (INCLUDES): Add top_builddir so glibconfig.h
        is found properly when build srcdir != builddir. (Patch from
        Eric Lemings)

2000-05-13  Tor Lillqvist  <tml@iki.fi>

        * makefile.mingw.in
        * gobject.def
        * gobject.rc.in: New files, for Win32 (mingw) build.

        * Makefile.am: Add to EXTRA_DIST. Add rules to produce the
        corresponding non-*.in files.

        * gtype.h: (Win32:) Mark _g_type_fundamental_last for
        export/import from DLL.

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-gtype.[hc]: GLib Type System implementation, heavily
        based on BSE's dynamic type system.
