mriedemhttps://review.openstack.org/#/c/202170/14:34
zzzeekmriedem: does this fail on py3.3 or we are only testing on py3.4?14:34

mriedemwell, we only test on 3414:34
zzzeekmriedem: maybe it has somethign to do with .pyc14:34

zzzeekmriedem: months ago I got into a huge flamewar on the list that I really didnt think we should be deleting .pyc files and it was b.c. i had dealt a lot with this in alembic14:35
zzzeekmriedem: e.g. they are important14:35
zzzeekmriedem: anyway, the test here seems to be looking for self.assertRaises(exceptions.InvalidScriptError, self.cls.verify_module, path)14:35
zzzeekmriedem: and instead its getting ImportError14:35
mriedemwell, the migrate tests don't delete pycs first like nova does14:35

zigodims_: It's not if you don't apply haypo's patch on top of master.14:49
zigodims_: Upstream for memcached has been famously not reactive at all.14:49
zigoSo we cannot expect anything form him.14:49
zigoHowever, I've packaged master + haypo's patch in Debian already.14:49

dims_zigo: pointer to haypo's patch please?14:50
zigodims_: https://github.com/linsomniac/python-memcached/pull/6714:51
zigodims_: IMO, there's a bunch of upstream which we should blacklist. L'insomniac is one of them, the guys doing requests, and Gabriel (the guy doing sure and others). Plus we should get rid of mysqldb in the favor of pymysql. Though not for a single of these issues I have hope ... :(14:54

harlowjagordc so the pooled executor probably wasn't as tested now as it is being right now :-P21:09

harlowjagordc so that commit unified all the executors (yaaaa!)21:11

*** stevemar has joined #openstack-oslo21:12
gordcharlowja: i thought the code was taken from eventlet executor (which we've been using in ceilometer). looks like it's from thread.21:12
harlowjagordc yes, thread, but thread was using an executor object to do all the work21:13
harlowjathe executor abstraction (not the oslo.messaging executors, name confusion there) works also for all the other models21:13
