[Zope-dev] zc.async versus Zope 2 SIGTERM
Hi, zc.async's shutdown mechanism doesn't really work with Zope 2's SIGTERM handling: in my case it causes the Async's threaded dispatcher to die in the middle of something: Exception in thread Thread-1 (most likely raised during interpreter shutdown): Traceback (most recent call last): File /home/ctheune/local/lib/python2.6/threading.py, line 532, in __bootstrap_inner File /home/ctheune/local/lib/python2.6/threading.py, line 484, in run File /home/ctheune/gocept/code/...deployment/eggs/zc.async-1.5.4-py2.6.egg/zc/async/subscribers.py, line 115, in start File /home/ctheune/gocept/code/...deployment/eggs/Twisted-10.2.0-py2.6-linux-x86_64.egg/twisted/internet/base.py, line 1158, in run File /home/ctheune/gocept/code/...deployment/eggs/Twisted-10.2.0-py2.6-linux-x86_64.egg/twisted/internet/base.py, line 1172, in mainLoop type 'exceptions.AttributeError': 'NoneType' object has no attribute 'msg' This ends up in the worker not correctly unregistered and thus on next startup: Exception in thread Thread-1 (most likely raised during interpreter shutdown): Traceback (most recent call last): File /home/ctheune/local/lib/python2.6/threading.py, line 532, in __bootstrap_inner File /home/ctheune/local/lib/python2.6/threading.py, line 484, in run File /home/ctheune/gocept/code/webwork.deployment/eggs/zc.async-1.5.4-py2.6.egg/zc/async/subscribers.py, line 115, in start File /home/ctheune/gocept/code/webwork.deployment/eggs/Twisted-10.2.0-py2.6-linux-x86_64.egg/twisted/internet/base.py, line 1158, in run File /home/ctheune/gocept/code/webwork.deployment/eggs/Twisted-10.2.0-py2.6-linux-x86_64.egg/twisted/internet/base.py, line 1172, in mainLoop type 'exceptions.AttributeError': 'NoneType' object has no attribute 'msg' The funny thing is: although this instance didn't get to register it will then on regular shutdown: 2012-03-01 11:54:56 INFO zc.async.events deactivated dispatcher 8da98af0-5c95-11e1-a205-0024e8d50597 2012-03-01 11:54:56 INFO SignalHandler Caught signal SIGINT 2012-03-01 11:54:56 INFO Z2 Shutting down The first issue (fast shutdown) you can avoid by simply not sending SIGTERM and switching to always use SIGINT.

IIRC we (Jarn) ran into the same problem when running p.a.async. Our solution was to switch to using SIGINT for process shutdown. We used supervisor, so for each Zope process section we added stopsignal=INT But on unexpected process or server restarts, we still had stuck workers once in a while. We never had the time to investigate, so just handled those manually.
