Eva-iHello10:21
Eva-iSeems like we broke something in python-zaqarclient. Dsvm gates fail on "test_subscription_create" and "test_subscription_delete" tests. I'll try to find the problem.10:23
mdnadeemEva-i, yes me too face same issue10:30
mdnadeemEva-i, ping10:50
Eva-imdnadeem: pong10:50
mdnadeemregarding https://bugs.launchpad.net/python-zaqarclient/+bug/153277610:50
openstackLaunchpad bug 1532776 in Python client library for Zaqar "Invisible conflict during creation of some resources " [Undecided,New] - Assigned to MD NADEEM (mail2nadeem92)10:50
mdnadeemAs of now, zaqar server update resource if a resource already exist10:51
mdnadeemfor the time being , i think zaqar client should also do the same10:51
Eva-imdnadeem: aha, I see now10:52
mdnadeemEva-i, for time being , i think i would update it according to zaqar server behaviour10:53
mdnadeemand later on when i implement spec, when zaqar server nature will change at that time we will change client side too10:53
mdnadeemwhats say??10:53
Eva-imdnadeem: yes, that's very nice =)10:54
mdnadeemEva-i, cool10:54
mdnadeemEva-i, Thanks for your comment on spec https://review.openstack.org/#/c/246147/10:55
Eva-iseems like my bug report then unneeded10:56
mdnadeemEva-i, Your point make sense, however initially i and flwang discussed about it and agrees to add head, now i need to discuss flwang once again10:56
mdnadeemthen i will update spec accordingly10:56
Eva-imdnadeem: yes, let's see what flwang thinks10:56
mdnadeemEva-i, your bug is needed, for time being its a bug untill we implement the spec.10:57
Eva-imdnadeem: oki10:57
mdnadeemI will upload a patch soon for the same10:57
mdnadeem:)10:57

Eva-imdnadeem: btw strange, but python-zaqarclient subscription tests work good on my machine. I wonder why they fail on dsvm gate.11:04
mdnadeemEva-i, I see subscription test fail on zaqar server code  ,11:06
mdnadeemlet me check on python-zaqarclient side11:07
Eva-imdnadeem: where do you see failing on zaqar server code?11:07

mdnadeemEva-i, hmm11:12
therveEva-i, I believe those tests are not super robust11:13
therveIf the server gets into a specific state, they will fail11:13
therveI noticed that for example ""DELETE /v2/queues/beijing/subscriptions/None"11:14

Eva-iI collected some thoughts about dsvm gates tests fails, including "how to reproduce": http://paste.openstack.org/show/m7wFYz7lSPpquOl2VTsy/19:17

flwang1i noticed that as well21:09
Eva-iflwang1: so what do you think?21:09
flwang1that will be my 1st priority today21:09
flwang1there are some possibilities21:09
flwang11. functional test can't drop database after running21:10
flwang1which is causing some potential issue21:10
flwang12. a bug in subscription get code which is causing the uwsgi confused :)21:12
therveWe have this issue with uwsgi since beginning, it's annoying21:13
flwang1that's what i can tell now21:13
flwang1need to investigate21:13
*** njohnsto_ has quit IRC21:14
Eva-i1. I think this is not the first cause. Problem can occur even on the first run of test case. And if it occurs, subscription stays undeleted, causing subsequent runs of tests to fail.21:14
Eva-ioki21:14
flwang1therve: oh, really? i even don't know that, any more details?21:18
*** kgriffs is now known as kgriffs|afk21:18
therveflwang, Not really. But the bad status line error is masking the real error, whatever that is21:18
*** kgriffs|afk is now known as kgriffs21:20
flwang1therve: so does that mean there must be a bug in our code, uwsgi just masks the real issue, right?21:22
therveflwang, That's what I'd say yeah21:22
therveI can try something21:23
*** njohnston has joined #openstack-zaqar21:23
flwang1therve: cool, good to know21:23
openstackgerritThomas Herve proposed openstack/zaqar: DNM: don't use uwsgi on the default port  https://review.openstack.org/26657721:25
flwang1therve: hmm... so we're using websocket as the default transport?21:28
therveflwang, Not sure what you mean. No, probably?21:29
flwang1https://review.openstack.org/#/c/266577/1/devstack/plugin.sh21:29
*** mdnadeem has joined #openstack-zaqar21:29
flwang1i'm seeing the change you posted21:29
therveAh, yeah. We set the transport to websocket in the conf so that the zaqar-server process runs websocket21:30
therveAnd uswgi runs the wsgi transport21:30
therveMy change is a trick so that uswgi runs on a random port, and zaqar-server runs wsgi instead of websocket21:30
*** amitgandhinz has quit IRC21:31
flwang1therve: personally, i would prefer to run zaqar server with wsgi instead of websocket21:32
Eva-iDevstack starts two zaqars: websocket one(on port 9000 with unmodified zaqar.conf) and wsgi one (on port 8888 with transport driver overrided to wsgi)21:33
therveflwang, Well that's not the point. You can only run websocket with zaqar-server21:33
therveSo instead of having 2 zaqar-server, we have one and uwsgi21:33
flwang1therve: yep, i see21:34

ryansbtherve: or flwang1 : if you were using the zaqar CLI, and asked for a curl command format of a signed URL21:51
ryansbhow would you want the client-id field to work?21:51
ryansbjust generate a random one in the CLI?21:52
flwang1ryansb: i think end user should provide it, and maintain it21:52
therveryansb, Any reason not to display the one used?21:53
therveI mean the curl command appears when you actually make the call, right?21:53
ryansbwell one wasn't used to create the signed URL21:53
therveHum I don't get it21:53
ryansbtherve: so I'm adding a "--as-curl" option, that will output a formatted curl command21:54
therveOh21:54
ryansbso I was thinking folks would want to be able to just copy & paste the command21:54
therveThat's a bit weird21:54
ryansbI was thinking it'd be useful for folks using scripts to interact w/ zaqar21:54
therveI like the curl output when you're in debug mode, but I think that comes by default21:55
ryansbyeah, this is facing users (only when they ask for it)21:55
therveNot sure why signed urls would be a special citizen though21:55
ryansbbecause to make them work with curl you have to do: curl http://192.168.122.59:8888/v2/queues/fooq/messages --header 'URL-Signature: bb73361a3bfbc223c09b9e24b96f8bc49fc8eb167a25424bb6fb83ba7662c012' --header 'URL-Expires: 2016-01-13T21:50:13' --header 'URL-Methods: GET' --header 'URL-Paths: /v2/queues/fooq/messages' --header 'X-Project-ID: 419f66c62c2644aa82565f16adff2efe' --header "Client-ID:21:56
ryansb$(uuidgen)"21:56
ryansband I figured if you use the CLI to create a URL, you're unlikely to be interested in copy-pasting the 6 values (and knowing all the header names) to use the URL21:57
flwang1Eva-i: i run all the functional test locally many times, and all of them succeed21:57

openstackgerritRyan Brown proposed openstack/python-zaqarclient: Add CLI support for signed URLs  https://review.openstack.org/25373121:59

flwang1which can avoid the issue like we're seeing for the subscription patches22:04

flwang1vkmc: ryansb: thanks for the feedback22:12
flwang1Eva-i: yep, so i'm thinking if it's related to the code22:13
Eva-iflwang1: I think it's related to zaqar-server code.22:14
flwang1Eva-i: oh, really?22:14
flwang1but you sad when there is the connection issue, zaqar sever didn't get the request22:15
Eva-iflwang1: I inspected python-zaqar code thoroughly. Found nothing.22:15
flwang1haha :)22:16
Eva-iflwang1: between the client and zaqar there's uwsgi. Uwsgi for some reason drops connections.22:17
flwang1ok, at least it's a good news for me, the author of those subscriptions patches :D22:17
Eva-iI think the reason is somewhere in Zaqar code.22:19
Eva-iSomething conflicts with uwsgi22:19
Eva-iflwang1: you are also the author of Zaqar server's subscription section of transport. So still bad news for you =)22:21
