Subject: [PATCH] Improved Watchdog Support
|
|
|
|
Forced Watchdog Crash support and Improve Async Shutdown
|
|
|
|
If the request to shut down the server is received while we are in
|
|
a watchdog hang, immediately treat it as a crash and begin the shutdown
|
|
process. Shutdown process is now improved to also shutdown cleanly when
|
|
not using restart scripts either.
|
|
|
|
If a server is deadlocked, a server owner can send SIGUP (or any other signal
|
|
the JVM understands to shut down as it currently does) and the watchdog
|
|
will no longer need to wait until the full timeout, allowing you to trigger
|
|
a close process and try to shut the server down gracefully, saving player and
|
|
world data.
|
|
|
|
Previously there was no way to trigger this outside of waiting for a full watchdog
|
|
timeout, which may be set to a really long time...
|
|
|
|
Additionally, fix everything to do with shutting the server down asynchronously.
|
|
|
|
Previously, nearly everything about the process was fragile and unsafe. Main might
|
|
not have actually been frozen, and might still be manipulating state.
|
|
|
|
Or, some reuest might ask main to do something in the shutdown but main is dead.
|
|
|
|
Or worse, other things might start closing down items such as the Console or Thread Pool
|
|
before we are fully shutdown.
|
|
|
|
This change tries to resolve all of these issues by moving everything into the stop
|
|
method and guaranteeing only one thread is stopping the server.
|
|
|
|
We then issue Thread Death to the main thread of another thread initiates the stop process.
|
|
We have to ensure Thread Death propagates correctly though to stop main completely.
|
|
|
|
This is to ensure that if main isn't truely stuck, it's not manipulating state we are trying to save.
|
|
|
|
This also moves all plugins who register "delayed init" tasks to occur just before "Done" so they
|
|
are properly accounted for and wont trip watchdog on init.
|
|
|
