[2.0] Global.onStop is not invoked.

[Justin]

Hi!

I need to do tasks when the process is killed.

So I simply did the instruction from the wiki, https://github.com/playframework/Play20/wiki/ScalaGlobal

But it simply does not work.

Help me, please.

Thanks, 

Justin

Do you 'kill' your application or do you 'shut it down'? Because, I think, it makes sense Global.onStop is not invoked when you kill your process.

I did 'kill' using 'play stop'.

Then, how do I 'shut down'?

Thanks for the reply, Leonard.

Okay, with killing I ment: 'kill -9 <pid>' or something like that. If you used 'play stop' it should do a normal 'shutdown' and it should invoke Global.onStop. It sounds like a bug. I can't help you any further right now, hopefully someone else can.

It should work, maybe there is a bug. Please file a ticket in the tracker.

To resolve the problem, I have read through the source codes of Play framework 2.

It does not seem that the framework always call the 'onStop'

'onStop' is called only if the application runs with the command 'play run' and it's stopped by pressing CTRL + D.

As of version 2.0, in order to do something before the application stops, you need to use 'Runtime.getRuntime.addShutdownHook'.

It is the way that the play framework deletes the 'RUNNING_ID' file.
(see src/main/scala/play/core/server/NettyServer.scala)

You may get more information on 'addShutdownHook' from the below link.

It'd be very helpful if the committers confirm this.
