therveflaper87, So getting somewhere on that bad status line error?09:19
flaper87therve: not yet, for now I'm focusing on getting the redis gate to the same state of mongodb's so I can then figure out the BadStatusline issue09:20
flaper87therve: it's non-deterministic09:20
flaper87:/09:20
flaper87I think the above run will get the redis gate to the same state as mongodb's09:21
flaper87(last famouse words)09:21
flaper87if you have ideas/hints, please, share :D09:22
therveYep :)09:29
therveI'm trying to reproduce locally09:29

therveflaper87, I think I know why09:45
therveOn the first tests mongo seems to be creating the databases and it takes a long time09:46
therveuwsgi times out the requests before it responds09:46
flaper87therve: ahhhhhhh, that's entirely possible. Weird thing, though, is that we're using `--smallfiles` in mongo to make db creation smaller and faster09:47
* flaper87 shrugs09:47
therveHum, I should use that locally :)09:54
therveflaper87, Is it set in devstack?09:54
flaper87therve: it is, in the configure_mongodb function09:55
flwang1morning09:55
flaper87LOL09:55
flaper87it isn't there09:55
flaper87WHAT THE FUCK?09:55
therveHeh09:56
flaper87therve: I'll add it in this patch09:56
flaper87lets see if it behaves well now09:56
therveWe probably increase nssize uselessly too09:58
flwang1flaper87: a question for mongodb master09:59
flaper87therve: yup, likely10:00
flwang1did you mean smaller nssize will make the database creation fater?10:00
flaper87flwang1: yo10:00
flaper87flwang1: no, there's a "smallFiles" flag that makes DB files smaller10:00
flaper87That reduces the free space requirements but increases the partition and number of files in the FS10:00
flaper87nssize just handles the number of collections that are allowed to exist10:01
therveflaper87, Removing nssize and passing smallfiles makes it work for me10:01
flwang1therve: cool10:01
* flwang1 just learned something new10:01
flwang1therve: btw, did you see some leaking database after test running?10:02
flaper87therve: nssizes won't change anything. smallFiles is what is making it work10:02
flaper87I thought we were using that10:02
flaper87jeeez10:02
therveflwang1, Not sure how I would see that10:05
flwang1after running the zaqar test, use mongodb shell,  issue 'show databases;'10:06
openstackgerritFlavio Percoco proposed openstack/zaqar: WIP: Fixing gate  https://review.openstack.org/22106810:06
flwang1i'm going to create a bug for that, so it would be nice if you can confirm at your most convenience10:07
therveflwang, And?10:07
flaper87flwang1: I think there are some tests not deleting dbs, that's one more thing to dig10:07
flaper87brb, lunch10:07
therveShould it be empty?10:07
flwang1therve: i think they should be removed after running10:07
therveHum, not sure why10:07
flwang1at a result, after several running, your disk will be full10:07
therveBut recreating the db for every tests will be bad too10:08
flwang1that's a good point10:09

therveflaper87, Do you have some time to chat about https://bugs.launchpad.net/zaqar/+bug/1493823 ?11:59
openstackLaunchpad bug 1493823 in zaqar "Zaqar wsgi transport doesn't have a default error handler" [Undecided,New] - Assigned to Thomas Herve (therve)11:59
flaper87therve: sure thing12:00
flaper87therve: that sounds like something we should have in liberty12:00
therveflaper87, So I noticed that some flavors methods don't catch all errors12:00
therveThe pattern everywhere else is to have a Exception handler in every single method, which I find a bit weird12:00
therveIt also returns 503 and not 500 for some reasons12:01
therveWhat do you think we should do? Just add the 500 handler for now ?12:01
flaper87therve: by "everywhere else" you mean OpenStack ?12:01
flaper87or in other places in Zaqar12:02
therveflaper87, In zaqar12:02
flaper87mmh, I'd avocate for a "global" catch on exception that will log the error and return the right error code12:03

openstackgerritFlavio Percoco proposed openstack/zaqar: Ensure group exists on updates  https://review.openstack.org/22172512:15
therveDang, falcon routing implementation is not great :/12:31
flaper87kgriffs: ^12:32
flaper87therve: what's blocking you?12:38
therveflaper87, Well I can't find a way to patch a method for testing, but that's not why I was mentioning the routing implementation12:40
therveWhile looking at the issue I pdb'd my way into way, and it's O(N) which is sad for a basic tree-like structure12:40

therveryansb, Good question12:52
ryansbthey may have fixed/changed that, who knows12:53
thervefalcon==0.1.10 oh :/12:53
therveSadness12:54
flaper87therve: we can update it, we just haven't had a good reason to12:55
therveflaper87, That'd be cool12:55
flaper87and when we started using falcon, the requirements story was completely different12:55
therveOnce we have a running gate :D12:55
* flaper87 can feel the preasure12:56

flaper87therve: do zaqarclient tests work all the time for you when using smallfiles ?15:01
therveflaper87, They worked one time :)15:06
therveI don't use the redis backend though15:06
flaper87therve: yup, I'm now trying to figure out the mongodb failures15:06
flaper87because I configured smallFiles but there are some tests still failing15:07
flaper87and they fail on the "delete" step, which is likely cleanup15:07
therveok weird15:07
flaper87but there's nothing in the wsgi logs15:07
flaper87and the error is still BadStatusLine15:07
flaper87:/15:07
flaper87I'll take another look at the logs, maybe my eyes are too used to that grey color15:07
therveWhat's the mongodb version?15:08
therveI have a more recent one, 2.6.915:12

openstackgerritFlavio Percoco proposed openstack/zaqar: WIP: Fixing gate  https://review.openstack.org/22106815:15
therveAh you changed the config file on ubuntu15:15
flaper87yeah15:15
therveflaper87, It doesn't look changed though15:15
flaper87but I just realized the sed command was not doing anything15:15
flaper87therve: :)15:15
therveAh :)15:15
flaper87I'm using the g'old echo >>15:16
therveYay progress15:16
flaper87I'm now using*15:16
flaper87lets see the results for that15:16
flaper87I hope that will work15:18
flaper87although that won't explain this: http://logs.openstack.org/68/221068/25/check/gate-tempest-dsvm-redis-zaqar/0fd9964/console.html#_2015-09-09_12_37_39_06315:18
