ddejarakhmerov: Hi, I have found possible issue in Mistral Mitaka10:22
rakhmerovddeja: hi Dawid10:22
rakhmerovwhat is that?10:22
ddejawith experimental feature "ACK after processing message"10:22
rakhmerovok10:22
ddejaOn my devstack I have oslo_messaging in version 4.6.110:23
ddeja(don't know why, since every OS service need >=4.0.0)10:23
ddejabut in this version they have change the class RPCDispatcher10:23
ddejathey removed one parapeter from __call__ method, which is then override in Nikolay patch10:24
ddejawhich results in  TypeError: __init__() got an unexpected keyword argument 'executor_callback'10:24
rakhmerovhm...10:24
ddejaIt look like mentioned parameter was not used for some time, so I'm not suprised that oslo team deleted it10:25
rakhmerovso what was the version for which Nikolay made this fix?10:25
ddejaI'm not sure, but for 4.0.0 it should be ok10:25
rakhmerovnmakhotkin: Nikolay, hi10:26
rakhmerovlet's ask Nikolay10:26
ddejaok10:26
nmakhotkinrakhmerov, hi!10:26
rakhmerovnmakhotkin: can you please read the last ~20 messages10:26
rakhmerovlooks like we have a problem with that oslo messaging related patch10:26
ddejaOK, I have just checked, the mentioned parameter was deleted in oslo_messaging 4.4.010:27
nmakhotkinok, I see10:27
ddejahttps://github.com/openstack/oslo.messaging/blob/4.4.0/oslo_messaging/rpc/dispatcher.py#L13010:27
ddejahttps://github.com/openstack/oslo.messaging/blob/4.3.0/oslo_messaging/rpc/dispatcher.py#L13010:27
nmakhotkinthat's very strange10:27
rakhmerovso what do we need to do?10:28
rakhmerovfix it and release RC3?10:28
nmakhotkinI think yes10:28
nmakhotkinwe could delete that parameter as well10:28
rakhmerovnmakhotkin: can you do this by tomorrow?10:28
rakhmerovtomorrow is the last chance for this10:29
rakhmerovto get it merged and ask for release10:29
ddejanmakhotkin: I don't think deliting it is good idea10:29
ddejasince Mistral requires oslo_messaging>=4.0.010:29
ddejaand in 4.0.0 this parameter is still present10:29
ddejabut, in 4.4.0, it is not10:29
nmakhotkinddeja: so we could check if it exists10:29
rakhmerovyes, that's what concerns me10:29
rakhmerovright10:29
rakhmerovhm... yeah, it would be better10:30
ddejaor maybe be more specyfic about oslo_messaging version?10:30
rakhmerovbut I suggest we leave a HUGE TODO there to warn about potential issues if oslo_messaging changes10:30
_gryfmh.10:33
_gryfguys, dosn't this parameter is with default value?10:34
_gryfif so, it can be simply removed from mistral implementation10:35
_gryfso that it will work with 4.0 and 4.4 and above at the same time, doesn't it?10:35

kongrakhmerov, nmakhotkin, akuznetsova please help to review the critical patch in stable/mitaka https://review.openstack.org/#/c/301930/22:08
kongI have discussed with release team already, it's ok we make a new release.22:09
kongand BTW, dims in release team suggested us to run a job against oslo-messaging master, ' just throwing in a LIBS_FROM_GIT=oslo.messaging is enough'22:10
kongI didn't know what's the exact meaning of it, akuznetsova, do you know what?22:10
kongI don't have the privilege to +2 for the stable branch, so, please merge it today, and I22:17
kongI'll submit a patch for release this afternoon or tonight in  my time zone (UTC+12)22:17
kongcheers, guys22:18
