Watchdog support #12

Open zipplet opened 8 years ago

zipplet commented 8 years ago

Add the ability for godaemon to check that the task is healthy, for example it could:

Write a message to the task stdin and wait for a special reply from the task stdout
Connect to a TCP port and send/receive a message
Run a user defined watchdog check script

This would allow godaemon to detect a hung/stalled task that is still running, and restart it.

I am considering adding alpha support for this via stdin/stdout checking initially only, as this may be needed urgently for a user of godaemon that would be satisfied with a stdin/stdout only watchdog for the moment.
