Subject: [PATCH] Create a thread to reap death process
|
|
||||||
|
|
||||||
ForkingWSGIServer use `SocketServer.ForkingMixIn` to implement a
|
|
||||||
multiprocess server. This class provides a workflow that collect
|
|
||||||
death process (process in Zombie status) before the
|
|
||||||
`process_request`. This means that this process itself will be
|
|
||||||
in Zombie status at the end of the request, that will be eventually
|
|
||||||
collected during the next `process_request`.
|
|
||||||
|
|
||||||
To minimize transient Zombie process, `ForkingWSGIServer` is
|
|
||||||
creating a daemon thread (via `threading.Timer`) to call the
|
|
||||||
collector every (by default) 5 seconds.
|
|
||||||
|
|
||||||
Fixes #810
