Subject: [PATCH] Fix race condition that could kill connections before they
|
|
were initiated
|
|
|
|
Because NetworkManagers are registered before they get their channel in
|
|
channelActive, the ServerConnection would remove them sometimes because
|
|
it thought they were disconnected. This commit fixes this by introducing
|
|
a 'preparing' variable that is true while the NetworkManager is not
|
|
initialized. The ServerConnection does not remove NetworkManagers with
|
|
this flag.
