Subject: [PATCH 1/2] tweener: Save handlers on target and remove them on
|
||
|
|
destroy
|
||
|
|
|
||
|
|
Saving handlers we had using the wrapper as a property of the object and delete
|
||
|
|
them when resetting the object state.
|
||
|
|
Without doing this an handler could be called on a destroyed target when this
|
||
|
|
happens on the onComplete callback.

Subject: [PATCH 2/2] windowAttentionHandler: disconnect signals before
|
||
|
|
destruction
|
||
|
|
MIME-Version: 1.0

|
The 'destroy' signal is emitted at the end of the destroy() method.
|
||
|
|
However the implementation of destroy() can end up emitting one of the
|
||
|
|
signals we connect to on the window, causing us to re-enter destroy
|
||
|
|
from its callback.
|
||
|
|
That will in turn lead to some objects getting disposed twice, which
|
||
|
|
produces a stack trace like the following one.
|
||
|
|
|
||
|
|
This commit fixes the issue by overriding the destroy() method instead
|
||
|
|
of connecting to the signal, which allows us to disconnect the signal
|
||
|
|
handlers from the window at an earlier time and avoid re-entrancy.
