Shut down the eel server less aggressively #337

Closed samuelhwilliams closed 4 years ago

samuelhwilliams commented 4 years ago

At the moment, every time a websocket connection closes, we check 1 second later to see if there any any connections open. If a user opens and terminates multiple websocket connections, this can mean that one of the earlier "1 second laters" comes along during a later shutdown/reconnect and closes the server, despite the user navigating through the app in a reasonable way.

This patch moves this check to a "spawn later" gevent greenlet that can be terminated and rescheduled. Every time a websocket is closed, we cancel any previously-running check and schedule a new one for 1 second in the future, which should mean that Eel shuts down less often during valid navigation step/s.

Fixes #248
