tongli | when 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 |
tongli | can anyone tell why it behaves like that? | 13:29 |
dhellmann | tongli: that's not what I would expect | 13:33 |
tongli | @dhellmann, right, that is very strange. | 13:33 |
tongli | to recreate this is very simple. | 13:33 |
tongli | http://docs.openstack.org/developer/oslo.messaging/notification_listener.html | 13:34 |
tongli | that is the program, | 13:34 |
tongli | I will send out an email to the mailing list. | 13:34 |
dhellmann | what is the notification endpoint doing when it sees the message? | 13:35 |
tongli | the endpoint simply write to a log in my code, it is just to test the behavior. | 13:38 |
tongli | like this. | 13:38 |
tongli | class InfoEndpoint(object): | 13:38 |
tongli | def info(self, ctxt, publisher_id, event_type, payload, metadata): | 13:39 |
tongli | logging.info(payload) | 13:39 |
tongli | that is all what the endpoint does | 13:40 |
tongli | when using blocking as executor, the program runs ok. | 13:41 |
tongli | when 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 |
tongli | The magic may be here. https://github.com/openstack/oslo.messaging/blob/master/oslo/messaging/_executors/impl_eventlet.py | 13:42 |

dhellmann | mriedem: according to oslo/messaging/opts.py they go in the DEFAULT section, probably for backwards compatibility | 18:00 |

tongli | @dims, ping. | 18:10 |
dims | tongli, pong | 18:13 |
tongli | @dims, I posted a question earlier regarding the oslo.messaging executor. | 18:14 |
tongli | I also sent an email to the openstack mailing list, I wonder if you can shed some lights on the question. | 18:15 |
dhellmann | tongli: I just posted a response to your ML question | 18:15 |
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 |
dhellmann | tongli: 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 out | 18:16 |
dhellmann | I don't know for sure that adding the monkey patching is going to fix the problem, but it might help | 18:16 |
tongli | ok, let me try that. I am not aware Ceilometer calling that. | 18:17 |
tongli | in ceilometer cli.py, we have this eventlet.monkey_patch(socket=True, select=True, thread=True) | 18:19 |
tongli | let me give it a try. Thanks Doug. | 18:20 |
dhellmann | tongli: let me know if that doesn't work | 18:31 |
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 |
dims | tongli, magic of greenlet :) | 18:45 |
*** markmcclain has joined #openstack-oslo | 18:45 | |
tongli | @dims, I will look at the code and see if I can get a clue. Thanks. | 18:45 |
