Subject: [PATCH 18/18] BUG/MINOR: lua: always detach the tcp/http tasks before
|
|
freeing them
|
|
|
|
In hlua_{http,tcp}_applet_release(), a call to task_free() is performed
|
|
to release the task, but no task_delete() is made on these tasks. Till
|
|
now it wasn't much of a problem because this was normally not done with
|
|
the task in the run queue, and the task was never put into the wait queue
|
|
since it doesn't have any timer. But with threading it will become an
|
|
issue. And not having this already prevents another bug from being fixed.
|
|
|
|
Thanks to Christopher for spotting this one. A backport to 1.7 and 1.6 is
|
|
preferred for safety.
