Sig,
The most important words in there are "critical section." Carry on :)
Oh, please. This is not too hard to code.
My mind rolling around following choice(s) (there may be others i don't see). What would be a proper way to handle error during #finalize.
[ executor finalize ] on: Error do: [:ex | self handleFinalizationError: ex "where self is registry" ].
or:
[ executor finalize ] on: Error do: [:ex | executor handleFinalizationError: ex ].
of course, i should catch this error in test, so i can verify that:
a) test is get notified upon synthetically made error b) no matter what i do inside error handler (up to 'Processor activeProcess terminate'), a finalization process continues working (or restarts without losing remainder of executors).
I agree it should be the executor doing handling. However, if you get to this point, the executor already had the chance to do so in the finalize method itself, so I don't really see the point of sending it back.. Personally, I feel the only promises FinalizationRegistry should make wrt. to errors during finalization, is it should never lead to: - termination of the (or a) finalization process, - discarding another finalization action. IE I am perfectly fine with an error here being thrown in your face (hopefully in a somewhat debuggable way, unlike what happened in your first example when removing the error-swallowing), as you've already passed the point a correction should be made, and there's nothing more intelligible to do than making sure everything keeps working, and inform of the error. (Pretty sure the error swallowing was a quick hack for keeping everything working in the first place ;) ) Cheers, Henry
