Subject: [PATCH] clutter: Bail out and warn on reentry into mapping/unmapping
|
|
cycle
|
|
|
|
There's a bunch of crashes right now where the assertions in
|
|
clutter_actor_set_mapped() after calling the map/unmap() vfuncs are
|
|
failing. The only way this can happen is by re-entering
|
|
clutter_actor_set_mapped() during the map/unmap recursion.
|
|
|
|
The reason for those crashes is that the shell hides/shows some actors
|
|
in response to crossing events and key-focus changes. These in turn get
|
|
triggered by the newly introduced ungrabbing of ClutterGrabs when an
|
|
actor gets unmapped, which triggers GRAB_NOTIFY crossing events and
|
|
key-focus changes.
|
|
|
|
Since these situations are hardly avoidable (it's a valid use-case to
|
|
hide/show something in response to a crossing/key-focus event), catch
|
|
the set_mapped() call early while we reenter the mapping machinery and
|
|
log a warning instead of crashing.
