bnemeckgiusti: I saw there was another api breaking change proposed to oslo.messaging.15:06
bnemecDid we decide what to do with the previous one?15:06
kgiustibnemec: I approved the previous one - there were no meaningful uses of it according to codesearch15:07
bnemecOkay, and I see you pushed back on the new one since it's still in use.15:07
kgiustibnemec: the new one I'm a bit hesitant, just given the timing and the number of references to it15:07
bnemecConsidering that, I'm inclined to agree that it should just wait until stein.15:08
bnemecThis isn't the ideal part of the cycle to be removing deprecated stuff.15:08
kgiustibnemec: yeah we've been dinged on doing that in the past15:08
bnemecOkay, let's hold off on that one then.15:09

bnemecAh, I see there is some question about whether we need this now.15:18

lbragstadpointing to https://review.openstack.org/#/c/578995/15:18
lbragstad#link https://review.openstack.org/#/c/578995/815:18
dhellmannI like the approach in the code patch, so we just need to get that working15:18
dhellmannI think we can skip the spec, right?15:18
bnemecYeah, that sounds good to me.15:19
lbragstadi think we can, too15:19
lbragstadi'm investigating the failure on https://review.openstack.org/#/c/578995/15:19
lbragstadthe type check failed again15:19
lbragstadi hope to get that passing today15:20
dhellmannis that the thing where it needs to support the deprecated values thing from oslo.context?15:20
lbragstadyeah...15:20

dhellmannhmm15:22
dhellmannmaybe we need to make that class in oslo_context public15:24
dhellmannwe're returning it anyway15:24
lbragstadyeah15:25
bnemecYeah, it seems a little weird to return a private class to callers.15:25
lbragstadi suppose it is getting consumed by other things that are calling a public method15:25
bnemecFor one thing, private objects don't get documented.15:25
dhellmannright on both counts15:25
dhellmannlet me play with the isinstance thing a little before we change that, though15:26
lbragstadok, let me know if you want to sync later dhellmann15:26
bnemecSounds like we have a plan to move forward anyway.15:27

*** openstack changes topic to "Open discussion (Meeting topic: oslo)"15:27
bnemecAnything else before we close?15:27
dhellmannlbragstad : isinstance is returning true for me when I instantiate a _DeprecatedPolicyValues15:27
lbragstadhmm15:27
dhellmannlbragstad : the logic in the if statement is wrong15:28
dhellmannI left a comment on the patch15:28
lbragstadchecking15:29
* lbragstad facepalm15:29
bnemecAh, that needs to be and?15:29
lbragstadfwiw - https://review.openstack.org/#/q/status:open+project:openstack/oslo.limit+branch:master+topic:claims-implementation15:29
dhellmannlbragstad : in fact you can pass a tuple of types as the 2nd arg to isinstance()15:29
lbragstadfor those that were interested in the oslo.limit library - i have some work up for that15:29
dhellmannwhich would make that expression shorter anyway15:29
lbragstaddhellmann: oh - nice15:29
lbragstadi should have dug deeper into the syntax of isinstance15:30
dhellmannoh, and since dict inherits from collections.MutableMapping you don't have to check dict separately15:30
bnemecI love it when someone else already wrote the code I need. :-)15:30
lbragstadyeah - this is my first stab at tinkering with context managers15:31
lbragstadstill need to handle the actual calling to keystone on __enter__ and whatnot, but those kinda lay the ground work15:31
lbragstads/those/those patches/15:31
bnemecFTR, oslo.limit won't be subject to Oslo feature freeze since it hasn't been released yet.15:32
lbragstadoh - cool15:32
bnemecSo we can continue to iterate on that for now.15:32
lbragstadgood deal...15:32
bnemecObviously it won't be able to be adopted by any other projects until after feature freeze, but we can make progress on our side.15:32
lbragstadit'd be cool to have something by the end of the release that is consuming the existing unified limit work in keystone15:33
lbragstadeven if it's PoC, it should get people on the ground running if they want to adopt it in early Stein15:33
bnemecYep, getting new stuff in early in the cycle is always good.15:34
lbragstadi'm trying to think of the best way to write up how to consume this15:34
bnemecI'm guessing it will look a lot like the presentation at summit.15:35
lbragstad#link http://specs.openstack.org/openstack/keystone-specs/specs/keystone/rocky/strict-two-level-enforcement-model.html#proposed-library-changes-consumption15:35
lbragstadyou mean ^ ?15:35
bnemecYeah, I think that was it.15:36
lbragstadyeah15:36
lbragstadi was also going to try and WIP a patch to nova that consumes it, but i'm wondering if that it too specific?15:36
bnemecSeems like a good idea to me.15:37
lbragstadsounds good15:37
bnemecIt's nice to have a demonstration of how something will be consumed.15:38

xgerman_Hi20:36
xgerman_I have a question about privsep20:36
*** e0ne has joined #openstack-oslo20:36
xgerman_So I have an API server which kicks off privileged commands. So I am starting privsep  (forking not rootwrap!) as root, which kicks of a Daemon as a server, and then seems to kick off a reciever thread (?), then I have gunicorn fork a worker with less priviliges. When I call a priviliged operation it sends the command to the server, executes, and the server sends it back — but my app never recieves the return and20:39
xgerman_locks. gunicorn kills the worker after timeout and restarts which really angers privsep since now it finds unhandled messages and locks even worse — not even willing to send anhything to the priviliged daemon20:39
