Subject: [PATCH 4/4] fix possible server deadlock in ih_sub_cancel
|
|
|
|
ih_sub_foreach() calls ih_sub_cancel() while inotify_lock is locked.
|
|
However, ih_sub_cancel() locks it again, and locking GMutex recursively
|
|
causes undefined behaviour.
|
|
|
|
Fix that by removing locking from ih_sub_cancel() as ih_sub_foreach()
|
|
is its only user. Also make the function static so that it won't
|
|
accidentally get used by other files without locking (inotify-helper.h
|
|
is an internal server header).
|
|
|
|
This should fix the intermittent deadlocks I've been experiencing
|
|
causing KDE applications to no longer start, and probably also
|
|
