1dc774a653 Remove g_type_init() calls
Very many testcases, some GLib tools (resource compiler, etc) and
GApplication were calling g_type_init().

Remove those uses, as they are no longer required.

This is not needed anymore.

f24d8247b3 Do not use static GTypeInfo and GInterfaceInfo
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.

10a3867a6e test high contention on closure reference counts to trigger and catch
Mon Aug  1 23:33:47 2005  Tim Janik  <timj@imendio.com>

        * tests/refcount/closures.c: test high contention on closure
        reference counts to trigger and catch non-atomic updates.

        * tests/refcount/objects.c:
        * tests/refcount/objects2.c:
        * tests/refcount/properties.c:
        * tests/refcount/properties2.c:
        * tests/refcount/signals.c:
        fixed up test and threading fundamentals. variables accessed from all
        threads need to be volatile. context switches are enforced by using
        g_thread_yield(), not g_usleep(1) which may result in busy waits on
        some platforms. for testcode, always consider all warnings and
        critical messages fatal. issue the currently running program on
        stdout. improved progress indicators.

        * tests/refcount/properties.c:
        * tests/refcount/objects.c:
        don't overdo the number of testing threads to keep the testing machine
        usable, 2 threads can produce as much contention as 20 if executing the
        same code.

        * tests/refcount/signals.c: only start 1 thread per object. GObject
        doesn't provide mutually exclusive object access, but only mutually
        exclusive reference count modification.

        * tests/Makefile.am: added closures test.

39ea11ce6b Make refcounting threadsafe by using atomic operations. (#166020, Wim
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)
