| 14:02:56 | bauwser | oh snpa | |
| 14:03:09 | bauwser | I was thinking we were loooking at the *live* migrate Task | |
| 14:03:24 | bauwser | nvm then | |
| 14:03:39 | bauwser | but I think we probably have the same for live-migration and rebuild | |
| 14:04:09 | bauwser | I'm just looking at that | |
| 14:04:10 | superdan | let me put this up to see if it breaks anything and/or appears to fix | |
| 14:05:08 | bauwser | okay | |
| 14:05:41 | bauwser | FWIW, live-migration is not having the same useless rehydratation | |
| 14:05:50 | bauwser | only if we have a not found spec | |
| 14:05:57 | bauwser | but we can remove the conditional | |
| 14:06:10 | superdan | yeah | |
| 14:06:15 | bauwser | so, I'm gonna fire a patch for that given we now have 100% of chances to have it | |
| 14:06:22 | superdan | alright | |
| 14:06:25 | openstackgerrit | Matt Riedemann proposed openstack/nova master: remove i18n log markers from nova.api.* https://review.openstack.org/448082 | |
| 14:07:22 | mriedem | yay my sump pump is running every other minute | |
| 14:07:24 | mriedem | weeee | |
| 14:07:55 | superdan | mriedem: http://imgur.com/DWMGBJW | |
| 14:08:27 | mriedem | which is which? | |
| 14:08:29 | mriedem | blue is rain? | |
| 14:08:34 | superdan | seconds on the left, inches on the right | |
| 14:08:44 | superdan | runtime seconds per hour, that is | |
| 14:09:11 | superdan | oh and green is rain | |
| 14:09:13 | bauwser | interesting | |
| 14:09:19 | bauwser | we don't build houses this way | |
| 14:09:30 | bauwser | is that for collecting rain ? | |
| 14:10:10 | bauwser | because I have a drain running all around my house but the gravity does the rest :) | |
| 14:10:25 | bauwser | anyway | |
| 14:10:37 | superdan | bauwser: if you're below grade that doesn't work :) | |
| 14:10:55 | sdague | superdan: or that there is elevation changes | |
| 14:11:11 | bauwser | superdan: ah correct then | |
| 14:11:19 | sdague | the midwest water table being 1' below the surface and everything flat is quite a thing | |
| 14:11:23 | superdan | yeah | |
| 14:12:01 | bauwser | do you collect that into pipes, or do you spill the water in your garden ? | |
| 14:12:31 | openstackgerrit | Dan Smith proposed openstack/nova master: Remove legacy regeneration of RequestSpec in MigrationTask https://review.openstack.org/449640 | |
| 14:12:36 | mriedem | in my neighborhood, you wash it down the hill to the suckers at the bottom, | |
| 14:12:36 | superdan | bauwser: mine goes into the storm drain | |
| 14:12:37 | leakypipes | bauwser: spill. :) | |
| 14:12:43 | mriedem | which unfortunately is me and another guy after me | |
| 14:12:46 | bauwser | interesting | |
| 14:13:08 | bauwser | because yet another regulation here is to defend us spillinh | |
| 14:13:16 | mriedem | supposed to be graded to drain into catch baskets that pump it into a pond further down the way | |
| 14:13:29 | bauwser | but rather collecting all the rain into pipes that are transfered to a specific collecting tank | |
| 14:13:36 | bauwser | that's a rain network | |
| 14:13:45 | superdan | bauwser: == storm drain | |
| 14:14:08 | mriedem | sometimes i hear you get a drunken frenchman drown in one of those and then he clogs up the pipes | |
| 14:14:15 | superdan | hah | |
| 14:14:28 | mriedem | stories to scare your kids, | |
| 14:14:33 | mriedem | like ringing doorbells | |
| 14:14:51 | bauwser | hah | |
| 14:17:40 | bauwser | superdan: what will be the name of your branch for cleaning up the migration task ? I'd ideally put it on the same gerrit topic | |
| 14:17:53 | superdan | bauwser: the bug? see above ^ | |
| 14:18:08 | bauwser | superdan: cool | |
| 14:22:21 | mdbooth | mriedem: Thanks for sorting out the connect/disconnect thing | |
| 14:22:32 | mdbooth | ABCs don't do what we want though, unfortunately | |
| 14:22:52 | mdbooth | All an ABC does is ensure that subclasses implement abstract methods | |
| 14:23:02 | mdbooth | It doesn't actually do any checking of the signatures of those methods | |
| 14:23:09 | mdbooth | So... not all that useful tbh | |
| 14:23:14 | mriedem | mdbooth: why not? if you change the signature on an abstractmethod, and fail to adjust any classes that inherit from the ABC, they will blow up | |
| 14:23:31 | mriedem | mdbooth: i'm saying make the actual connect/disconnect_volume methods abstractmethods | |
| 14:23:38 | mdbooth | Case in point: RemoteFilesystemDriver is an ABC, and none of its subclasses have the correct signature for copy_file | |
| 14:24:00 | mdbooth | mriedem: Yeah, that's fine. But that will only assert that subclasses implement them | |
| 14:24:06 | mdbooth | There's no signature checking | |
| 14:24:12 | mdbooth | So it wouldn't catch this error | |
| 14:24:57 | mdbooth | Anyway, I agree that a test for this would be good, and probably useful in a few different places | |
| 14:25:15 | mdbooth | My first thought was to look for an existing tool, and I gave pylint a go | |
| 14:25:35 | mdbooth | However, pylint would be wildly impractical unfortunately. | |
| 14:25:51 | mdbooth | Getting a clean pylint job would be more work than getting python3 working, I think. | |
| 14:26:31 | mdbooth | So, I was considering writing some kind of introspection test for superclasses with abstract interfaces | |
| 14:26:38 | mdbooth | So you'd do something like: | |
| 14:27:13 | mdbooth | FSTest = SubclassCheckTest(SuperClassToTest) | |
| 14:27:22 | mdbooth | And it would generate you a test class | |
| 14:27:28 | mriedem | can't you scope pylint? | |
| 14:27:31 | mriedem | or whitelist? | |
| 14:27:40 | mdbooth | It all over the place | |
| 14:28:12 | mdbooth | I disabled almost everything, and I still had 95% false positives | |
| 14:30:41 | mdbooth | It did find RemoteFilesystemDriver.copy_file for me | |
| 14:31:00 | mdbooth | Although in this case, somebody has clearly updated all the implementations and forgotten to update the superclass | |
| 14:31:26 | nkorabli | Hi there! I noticed a multitenancy issue, here is a bug report: https://bugs.launchpad.net/nova/+bug/1675791 | |
| 14:31:26 | openstack | Launchpad bug 1675791 in OpenStack Compute (nova) "Instance created by demo user(non-admin), shelved by admin and unshelved by demo user --> ends up in error state " [Undecided,New] | |
| 14:31:26 | nkorabli | Need to know your opinions, to start fixing it! :) Thanks in advance! | |
| 14:31:29 | mriedem | ok i see what you mean about abstractmethod not checking the signature | |
| 14:31:30 | mriedem | that sucks | |
| 14:31:33 | mriedem | i just tested locally | |
| 14:31:57 | mdbooth | mriedem: Anyway, how about the testclass generator? | |
| 14:32:01 | mdbooth | Overkill? | |
| 14:32:03 | mriedem | nkorabli: we already talked about this the other day | |
| 14:32:09 | leakypipes | np | |
| 14:32:15 | mdbooth | I think we could use it in a few places | |
| 14:32:16 | nkorabli | mriedem: Hi there! | |
| 14:32:29 | mriedem | nkorabli: the error during unshelve wasn't due to the tenant | |
| 14:32:38 | mriedem | it was most likely due to a failure to spawn the instance during unshelve | |
| 14:32:42 | mriedem | which put the instance into ERROR state | |
| 14:33:26 | nkorabli | mriedem: right, we did I just tested it with pure openstack (stable/newton) in devstack environment - and I see this error as well. | |
| 14:33:44 | mriedem | nkorabli: i've invalidated the bug, | |
| 14:33:51 | mriedem | nkorabli: have you checked the logs for errors during unshelve? | |
| 14:34:00 | mriedem | because there has to be an error in the logs if the instance is in error state | |
| 14:35:37 | nkorabli | I actually haven't found anything useful in the logs, but let my check one more time. | |
| 14:49:28 | bauwser | superdan: mriedem: quick question | |
| 14:49:39 | bauwser | superdan: mriedem: I'm about to clean up a bit of useless code in the conductor | |
| 14:50:25 | bauwser | superdan: mriedem: and I just notice that we do verify at every move operation if the affinity filters are present on the conductor side | |
