[Twisted-Python] global exception handler
Hello all, is there a possibility to have a global (application wide) exception handler in twisted application? I would like to stop application in case of any unhandled error in deferred callbacks. If application is run from twistd ..., is it correct to stop application like this? def quit(failure): log.err(str(failure)) reactor.callWhenRunning(reactor.stop) But the main problem is how to get this method called if exception is not handled by explicitly doing d.addErrback for each case.

It is possible to get a function called for all unhandled errors by adding a log observer (http://twistedmatrix.com/documents/current/core/howto/logging.html#auto5) but this logging only happens on garbage collection of the Deferred, which means it can be delayed indefinitely in some cases. ___ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python

The only output is: svn/releases Looking at the repo with "gitk --all", that appears to be the name of a branch that is completely disconnected from all other revisions.

Thanks! Jonathan's pointer to the list of revisions ought to be enough for me to start bisecting, and I'll try to figure out what's happening in Git as I go along.
