2007-08-08 Emmanuele Bassi <ebassi@openedhand.com>
Merge the clutter.git/threading branch.
* clutter/clutter-main.c:
* clutter/clutter-main.h:
* clutter/clutter-private.h: Add threading locking and unlocking
functions, to mark a critical section and access the Clutter API
from differen threads. Add an initialisation function and a function
to override the default lock aquisition and release functions, for
bindings and application-specific locking handling. Add MT-safe
versions of g_idle_add() and g_timeout_add() which will call the
functions under the main Clutter lock and without races. The
Clutter thread-safe implementation is basically the same used by
GDK, so the same caveats apply.
* clutter/clutter-actor.c:
* clutter/clutter-timeline.c:
* clutter/clutter-timeout-pool.c: Use the new threading API when
invoking idle and timeouts.
* clutter/eglnative/clutter-event-egl.c:
* clutter/eglx/clutter-event-egl.c:
* clutter/glx/clutter-event-glx.c:
* clutter/sdl/clutter-event-sdl.c: Acquire and release the main
Clutter lock when preparing, checking and dispatching the events
on the queue in every backend.
* tests/Makefile.am:
* tests/test-threads.c: Add a test case, showing how to use the
threading API and write thread-safe Clutter applications.
2007-08-08 Emmanuele Bassi <ebassi@openedhand.com>
* configure.ac: Bump up to 0.5.0 and start the new development
branch.
2007-08-07 Emmanuele Bassi <ebassi@openedhand.com>
* configure.ac: Bump up to 0.4.0.

* The functions must provide at least same locking functionality
* as the default implementation, but can also do extra application
* specific processing.
*
* As an example, consider an application that has its own recursive
* lock that when held, holds the Clutter lock as well. When Clutter
* unlocks the Clutter lock when entering a recursive main loop, the
* application must temporarily release its lock as well.
*
* Most threaded Clutter apps won't need to use this method.
