Eva-iflwang1: okay19:24
flwang1the new time will start from next week19:24
Eva-iflwang1: how do you think is this comment is always true: "the remaining messages will always be unclaimed as well" in here https://github.com/openstack/zaqar/blob/master/zaqar/storage/redis/scripts/claim_messages.lua#L5119:28
Eva-i?19:28
Eva-iflwang1: what if one message's claim is expired but messages after this messages are still claimed?19:30
flwang1Eva-i: i have to drive to office now, will ttyl19:34

flwangEva-i: back21:24
Eva-iflwang: oki21:25
flwangthe code you're referring is trying to claim a msg21:28
flwangsorry, several msg by msg ids21:28
flwangso what did you mean 'what if one message's claim is expired'?21:28
Eva-iflwang: yes, and the code assumes that if first unclaimed message is found, then all next messages in the list are unclaimed too21:29
Eva-iflwang: do you think it's correct?21:29
Eva-iflwang: ok, wait, I'll try to explain better21:31

Eva-iflwang: http://paste.openstack.org/show/U3vHgH9hRBaTMpZN59XG/21:37
flwangseems it's possible, but TBH, i never tried this before, so i think it deserves a test before opening a bug21:42
Eva-iflwang: okay, I'll test it21:43
Eva-iflwang: also can this script be executed simultaneously multiple times? For example two Zaqar instances using single redis database?21:44
flwangEva-i: i will send out a mail about the summary of our summit design sessions today so that we can be on the same page for the priorities21:45
Eva-iflwang: thanks for your work21:45
Eva-iflwang: this bug is not in priority, right? https://bugs.launchpad.net/zaqar/+bug/154813521:49
openstackLaunchpad bug 1548135 in zaqar "(Redis) Unable to claim messages after some messages expired" [Undecided,New]21:49
flwangEva-i: i will set it as high21:59
flwangEva-i: based on my rule, all the bugs break functions will be set as high21:59
Eva-iflwang: oh, oki. I'm writing a fix for it.22:01
flwangEva-i: thanks :)22:11
flwangEva-i: so in newton, you will be responsible for improving the notification format, is that ok?22:13
Eva-iflwang: yes, I would like that22:17
flwangEva-i: cool, and you're still working on the install guide, right?22:19
Eva-iflwang: yes22:19
flwangawesome22:20
flwangi will drive the api doc, btw22:20
Eva-iflwang: nice22:21
flwangnewton will be another busy release22:22
Eva-iflwang: I don't see Fernando (fribeiro) in chat. Did he left Zaqar?22:28
flaper87Eva-i: I believe he was at the summit but never attended Zaqar sessions22:30
Eva-iflaper87: hello, okay22:30
flwangflaper87: hi stranger22:31
flaper87flwang: 'sup bro!22:32
flaper87Eva-i: HIIIIIIII!22:32
flwangflaper87: i'd like to know your opinion about the pool group22:32
flaper87flwang: link?22:34
flaper87We talked about this at the summit, right?22:34
flwangflaper87: https://etherpad.openstack.org/p/newton-zaqar-summit-planning22:34
flwangif we should deprecated it and if we keep it, should we add a new api endpoint for it(i don't want to add it, TBH)22:35
Eva-iflwang: do you think I acted not the best way with fribeiro?22:36
flwangEva-i: sorry? i can't follow22:36
Eva-iflwang: I was too strict in my review of his first patch?22:37
flwangEva-i: oh, i don't think it made fribeiro upset :D22:38
Eva-iflwang: oki22:39
flwangEva-i: so don't worry about that22:40
Eva-iflwang: okay, I performed test and yes, it seems there is a bug: http://paste.openstack.org/show/6KYk1fPumWteuCR8aDIr/. Also found another bug during this. So now there are 3 bugs in Redis waiting to be solved.23:21
flwangEva-i: cool, thanks for working on this23:29
flwangEva-i: but i'm thinking another thing23:29
flwangwhat's the bad side if the msg is claimed again by same client23:29
Eva-iflwang: it might process it two times23:30
Eva-iflwang: if it's bank transaction, 2x money will be sent =)23:31
flwangEva-i: haha, could be, but generally the client should handle more :)23:32
flwanganyway, i agree it's a bug23:32
Eva-iflwang: okay, I'll make a report for this bug23:33
flwangEva-i: thanks23:45
