boris-42dhellmann apocalypse ^14:44
viktorsdhellmann: hi!14:45
dhellmannboris-42: the downtime?14:46
dhellmannviktors: hi!14:46
boris-42dhellmann yep=)14:46
dhellmannboris-42: we'll survive :-)14:46
dims:)14:47
viktorsdhellmann: I want to inform you, that or db-team (rpodolyaka, I159 and me) will be on vacation at from May 01 till May 1214:47
dhellmannviktors: ok, thanks for letting me know14:47
dhellmannviktors: should I let the infra team proceed with importing oslo.db when they are ready, or would you prefer that we wait until after the summit?14:48
rpodolyakathe sooner the better? :)14:48
dhellmannviktors: I'll be glad to monitor or assist or whatever they need14:48
dhellmannrpodolyaka: yeah, that's what I was thinking, too14:48
rpodolyakacool :)14:48
viktorssame for me :)14:48
dimshave a good vacation you all!14:49
rpodolyakadims: thanks!14:49
viktorsdims: thanks!14:50
* rpodolyaka sometimes thinks we have way too many holidays here in Ukraine...14:50
viktorsdhellmann: by the way, are you familiar with wsme? )14:50
dhellmannviktors: yes, a bit :-)14:51
* dhellmann thinks we don't have enough holidays here in the US14:51
viktorsdhellmann: please tell me, is there any way to validate parameter as "int or string" with wsme.types ?14:53
dhellmannviktors: do you mean that the type could be either an int or string?14:55
viktorsdhellmann: yes14:55
dhellmannviktors: that's not really something WSME wants you to do -- it wants you to pick a type. What's the use case you have in mind?15:00
*** shakamunyi has joined #openstack-oslo15:03
viktorsdhellmann: when we validate a dictionary, it's normal situation, that we have different types for values15:04
beekneemechandymaier: Oslo doesn't release the same way that the other projects do.15:04
*** beekneemech is now known as bnemec15:04
bnemecNot Friday anymore. :-(15:04
dhellmannviktors: yes, well, WSME takes a strong stance on using consistent types in the API so it is easy for callers to know what to pass15:05
bnemecandymaier: oslo-incubator code is included directly in the other projects, and the oslo* libraries release largely on their own schedule.15:05
viktorsdhellmann: Ironic have it's own workaround for this situation - see https://github.com/openstack/ironic/blob/master/ironic/api/controllers/v1/types.py#L15315:05
viktorsdhellmann: is it correct? Or this situation should be handled by wsme?15:07
dhellmannviktors: we could probably get that into WSME; I didn't know about it15:14
viktorsdhellmann: ok, we (me or Yuriy Zveryanskyy) will make a patch to wsme soon15:24

dhellmannbnemec: I think I hit -1 on https://review.openstack.org/#/c/90577/ just as you were approving it :-)15:48
dhellmannbnemec: it's not a big issue, we can clean it up in another patch15:48
bnemecdhellmann: Whoops.15:49
dhellmann:-)15:49
bnemecdhellmann: I can just drop the +A before it merges too.15:49
dhellmannbnemec: did you look at the comment? maybe I'm wrong anyway15:49
bnemecdhellmann: Thinking...15:50
bnemecdhellmann: Actually, I'm not sure that even needed to be changed.  The "no str()" rule is to make translation work, and since that isn't translated the str() doesn't matter.15:52
dhellmannbnemec: I can never remember how the automatic casting works, so I always just do it explicitly15:52
dhellmannbnemec: true15:52
bnemecI'm guessing he grepped for _ and that line showed up.15:52
dhellmannbnemec: hmm, if queues is a list that's going to trigger an error on the string interpolation now15:53
bnemecdhellmann: It looks like a dict, based on line 135.15:54
dhellmannbnemec: ah, ok15:54
bnemecIt looks like we're okay with a list too, but not a tuple.15:55
bnemec>>> 'something: %s' % {'foo': 'foo', 'bar': 'bar'}15:55
bnemec"something: {'foo': 'foo', 'bar': 'bar'}"15:55
bnemec>>> 'something: %s' % ['foo', 'bar']15:55
bnemec"something: ['foo', 'bar']"15:55
bnemec>>> 'something: %s' % ('foo', 'bar')15:55
bnemecTraceback (most recent call last):15:55
bnemec  File "<stdin>", line 1, in <module>15:55
bnemecTypeError: not all arguments converted during string formatting15:55
dhellmannbnemec: hmm, ok, that's a little surprising15:55
dhellmannagain, I tend to do this stuff explicitly so I don't have to remember these nit picky rules :-)15:56
dhellmannbnemec: so I think we're safe with the patch as-is then?15:56
bnemecdhellmann: The Zen would agree with you.  I'm pretty sure it says something about explicit is better than implicit. :-)15:57
dhellmannbnemec: :-)15:57
bnemecdhellmann: I think it should be fine, yeah.15:57
dhellmannbnemec: ok15:57
* dhellmann avoids approving any more changes with the gerrit about to go offline15:58
bnemecYeah, that's a good point.  I was trying to get a few reviews in before I couldn't. :-)15:58

dhellmannpraneshp: pong19:24
praneshpHello dhellmann, been searching for ypu for a while :)19:24
praneshpI’m looking for some feedback on https://blueprints.launchpad.net/oslo/+spec/configure-tcp-keepalive19:24
dhellmannpraneshp: I think when I went to reply to you earlier you weren't here in the room19:25
praneshpOh, sorry dhellmann19:25
dhellmannnp, just letting you know I had seen your message before :-)19:25
praneshpdid you have feedback on that? I am new to the bp process, so didn’t know how it worked19:29
praneshpI submitted to nova first, and those guys just replied on gerrit reviweing19:30

-openstackstatus- NOTICE: Gerrit upgrade to 2.8 complete. See: https://wiki.openstack.org/wiki/GerritUpgrade Some cleanup tasks still ongoing; join #openstack-infra if you have any questions.19:32
dhellmannpraneshp: I'm not clear on how you mean to implement the keepalive change -- isn't that a kernel setting?19:34
dhellmannpraneshp: we don't, yet, have a specs repository for oslo19:34
praneshpdhellmann: No. You can also set it at the application level. We do that at Yahoo19:35
dhellmannpraneshp: bugging me on IRC is probably the best approach for now :-)19:35
dhellmannpraneshp: ah, ok19:35
praneshpdhellmann: yeah, so how are bps reviewed? Just commment on the whiteboard?19:35
dhellmannyou talk about config options, but not really how those will be used by the implementation19:35
dhellmannpraneshp: yeah, the whiteboard for now19:35
praneshpdhellmann: we do it for nova alone, but a couple of other projects do exactly the same thing nova does (eg cinder)19:36
dhellmannpraneshp: ok, this isn't a feature I'm familiar with so I may just need a pointer to code or something19:36
praneshpHmm. I’ll update. I expect that oslo will provide a function to set keepalive values, and files like https://github.com/openstack/cinder/blob/master/cinder/wsgi.py19:36
praneshpdhellmann:  sure. WIll bug you again with the code tomorrow :)19:37
dhellmannpraneshp: if you want to add details to the bp in launchpad, I'll subscribe there so I see a notification19:38
praneshpif you jsut wanted a random document explaining this, here is what I used. TCP Keepalive HOWTO http://tldp.org/HOWTO/TCP-Keepalive-HOWTO/index.html19:38
praneshpyeah, adding19:38
dhellmannpraneshp: is the keepalive just set with setsockopt()? If so, I don't need a code sample19:39
praneshpdhellmann: yes19:39
praneshpjust socket.setsockopt()19:39
dhellmannpraneshp: ok, just mention that in the bp so when I inevitably forget I can find it again :-)19:40
praneshpNova already does it, actually19:40
praneshpI just want the values to be tunable19:40
praneshp*tuneable. Whatever the spelling is19:40
dhellmannyou could also add a note about which library you see this new module ending up in eventually, https://wiki.openstack.org/wiki/Oslo/GraduationStatus19:40
dhellmannpraneshp: sure, that makes sense19:40
praneshpthanks dhellmann19:42
dhellmannpraneshp: np, thank you for putting this together, it looks like a good addition19:51
