esbergluthorst: efried: adreznec: They are asking for core review for the above. Just a doc change13:14
esbergluCan I W+1 something like that? I think when I was added to the cores it was just for release stuff13:14
*** mdrabe has joined #openstack-powervm13:14
thorstI'll take a peak in a bit13:14
adreznecwhy would we go back and update an old spec?13:15
adreznecThat looks like what he's doing13:15
efriedThat's what I was thinking13:15
efriedI mean, meh, I don't mind, but unless the old link is broken, I'm not sure I see the point.13:15
efried(the old link is not broken)13:15
adreznecI mean I guess it probably should have been that way to begin with, but it's kind of a waste... it's not like anyone is going to reference the spec again13:15
esbergluI was thinking it was because liberty is EOL13:15
* adreznec shrugs13:15
esbergluBut again idk what the point of the spec update is13:16
efriedNew openstack contributor, trying to rack up some changes, I guess.13:17
adreznecesberglu: To answer your earlier question, you should have authority to W+1 changes like that I think13:18
adreznecAs per https://review.openstack.org/#/admin/groups/593,members13:19

thorst_afksorry to loop back, but to esberglu's review q.  One thing that I know was brought up at the PTG was that to many users, blueprints are the design and should be kept up to date14:16
thorst_afkto developers they're a point in time thing14:16
thorst_afkbut to users...they explain the system as it is today14:16
thorst_afkspeaking as someone who had to learn OpenStack...I can say I leaned just as heavily on the blueprints as I did the code.14:17
thorst_afknow just changing it from liberty to newton...that's not really a big deal...but the broader question still holds true14:17
thorst_afk:-)14:17

thorst_afkefried: there?14:46
efriedYeah.14:46
thorst_afkhttps://review.openstack.org/#/c/465045/2/nova_powervm/virt/powervm/driver.py14:47
thorst_afknot sure I agree with your change request to arun14:47
efriedWhat, naming the kwarg?14:47
thorst_afkyep14:48
thorst_afksec....getting line from github14:48
efriedBecause the function we get passed in could be anything at all?14:48
efriedOr because you think it's actually wrong in this specific case?14:48
thorst_afkhttps://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L645814:48
thorst_afkhttps://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L6466-L646714:48
thorst_afkmostly because 'that's not what libvirt does'14:48
efriedYeah, libvirt is not perfect, dude.14:49
thorst_afktotes14:49
thorst_afkbut that's why I'm not sure14:49
thorst_afkso still digging....but I want to make sure recover_method comes from known places and isn't something that can just swap in or out14:49
efriedNote that even if we get passed a function where migration_data isn't a kwarg, as long as it's called migration_data, us naming the kwarg will still work.14:50
thorst_afko yeah...no you're right14:50
thorst_afkcomes from exactly one place14:50
efriedAnd I would argue that if we suddenly start getting a function that doesn't conform to that spec, we WANT to break.14:50
thorst_afkalright...nevermind14:50
efriedLike we did this time.14:51
efriedExcept we want to break more explicitly14:51
efriedWhich naming the kwarg ought to help with.14:51
thorst_afkyeah yeah, you're right14:51
thorst_afkI should never doubt  :-)14:51
efriedI'm not super comfortable about it either, for the record.14:51
thorst_afkwell, at least gets it going14:51
efriedPassing in a method with an unknown spec is pretty brittle (and tough as hell to maintain/debug).14:51
thorst_afkyeah, but if all drivers are in tree...it'd be easy to fix14:52
thorst_afkthe problem is out of tree specific really14:52
efriedThe docstring doesn't explicitly describe the method sig - just points to the method they're thinking they're going to use, probably, maybe, if you're lucky.14:52
efriedYes, agree.14:52
thorst_afkwhich is why we go into the tree14:52
efriedThough even in-tree is going to be questionable whether we get swept into changes there.14:52
efriedCause it's not just going to break on pep8 or something.14:53
efriedBecause freakin function pointer.14:53
thorst_afkagree.14:53
thorst_afkwell, we've got arun  :-)14:53
efriedI suppose we oughtta have a better unit test.14:53
efriedOne that invokes the base driver method14:53
efried...but still, the thing we would want to check is the call to their method that gets passed in.14:54
efriedWhich we still don't know about until runtime.14:54
efriedSo catch-22.14:54
efriedThis is about the best we can hope to do.14:54
thorst_afkauto spec the method from the compute manager14:54
thorst_afkis that a thing?14:54
thorst_afkauto spec a mock of it (cause we don't really want to call it, but we want to maintain its signature)14:55
thorst_afk(whatever said signature is)14:55
thorst_afkI need to learn that auto spec magic some day14:55
thorst_afkback when I can code again...14:55
efriedYeah, that would be okay until they swap whatever method they're passing in, and leave the old one hanging around.14:55
efriedBut that would be a good idea here, you're right.14:56
thorst_afkyeah...but better.14:56
