We had 2 issues. 1) Log4J2 Shutdown hook seemed to be causing issues as it shutdown logger while we still needed it 2) ServerShutdownThread needs to stay alive until server is shutdown to keep jvm open. It appears SIGINT is handled differently than SIGTERM, as SIGINT worked correctly. But this will make both methods work.

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.
