tongliwhen using oslo.messaging eventlet executor with default rpc_thread_pool_size of 64, the threads handling messages will be blocked until all threads in the pool has a task to run.13:28
tonglican anyone tell why it behaves like that?13:29
dhellmanntongli: that's not what I would expect13:33
tongli@dhellmann, right, that is very strange.13:33
tonglito recreate this is very simple.13:33
tonglihttp://docs.openstack.org/developer/oslo.messaging/notification_listener.html13:34
tonglithat is the program,13:34
tongliI will send out an email to the mailing list.13:34
dhellmannwhat is the notification endpoint doing when it sees the message?13:35
tonglithe endpoint simply write to a log in my code, it is just to test the behavior.13:38
tonglilike this.13:38
tongliclass InfoEndpoint(object):13:38
tonglidef info(self, ctxt, publisher_id, event_type, payload, metadata):13:39
tonglilogging.info(payload)13:39
tonglithat is all what the endpoint does13:40
tongliwhen using blocking as executor, the program runs ok.13:41
tongliwhen using eventlet as executor, then the threads will block until all the threads get something to run, then some of the threads will run.13:42
tongliThe magic may be here. https://github.com/openstack/oslo.messaging/blob/master/oslo/messaging/_executors/impl_eventlet.py13:42

dhellmannmriedem: according to oslo/messaging/opts.py they go in the DEFAULT section, probably for backwards compatibility18:00
dimsdhellmann, i see it here - http://markmail.org/message/q43hadd2avhu2h3318:01
mriedemdhellmann: thanks18:02

tongli@dims, ping.18:10
dimstongli, pong18:13
tongli@dims, I posted a question earlier regarding the oslo.messaging executor.18:14
tongliI also sent an email to the openstack mailing list, I wonder if you can shed some lights on the question.18:15
dhellmanntongli: I just posted a response to your ML question18:15
tongli@dhellmann, doug, I did not see your response. I checked awhile back, there was no response, did you just send?18:16
tongli@dhellmann, doug, I see it now.18:16
dhellmanntongli: yes, just a minute or two ago -- I was watching for your message on the openstack-dev ML and didn't see it on the other list until dims pointed it out18:16
dhellmannI don't know for sure that adding the monkey patching is going to fix the problem, but it might help18:16
tongliok, let me try that. I am not aware Ceilometer calling that.18:17
tongliin ceilometer cli.py, we have this eventlet.monkey_patch(socket=True, select=True, thread=True)18:19
tonglilet me give it a try. Thanks Doug.18:20
dhellmanntongli: let me know if that doesn't work18:31
tongli@dhellmann, doug, thanks, will reply to the email and indicate if it worked or not.18:35
tongli@dhellmann, doug, that did the trick. not sure why though,18:39
dimstongli, magic of greenlet :)18:45
*** markmcclain has joined #openstack-oslo18:45
tongli@dims, I will look at the code and see if I can get a clue. Thanks.18:45
