| [00:04] <StevenK> wgrant: With Component and Section preloaded, down to 70. | |
| [00:09] <wgrant> Excellent | |
| [00:09] <wgrant> What are the rest? | |
| [00:12] <StevenK> wgrant: PackageDiff and related LFA and LFC; SPPH; ArchivePermission | |
| [00:13] <wgrant> Right | |
| [00:18] <StevenK> wgrant: So I think it's reasonable | |
| [00:18] <StevenK> We've dropped 160 queries | |
| [00:52] <StevenK> wgrant: http://pastebin.ubuntu.com/1453695/ | |
| [01:15] <StevenK> wgrant: No thoughts at all, I see. | |
| [01:26] <wgrant> StevenK: Hmm | |
| [01:26] <wgrant> Looks reasonable so far | |
| [01:30] <StevenK> wgrant: Hmmm, given IPackageUploadSet.getAll() is the meat inside IDistroSeries.getPackageUploads(), and getAll() does the propertycache dance, I guess the other bug is sorted too? | |
| [01:31] <wgrant> StevenK: It probably is, but you need to check that the delegations to SPR's checker work | |
| [02:08] <wgrant> (by "work" I mean "don't issue tonnes of queries") | |
| [03:31] <StevenK> wgrant: Hmmm, something has broken the upload webservice tests | |
| [03:43] <wgrant> Oh? | |
| [03:44] <StevenK> wgrant: TestPackageUploadWebservice calls factory.makeBuildPackageUpload() (and then creates a BPR, but the factory call does that ...), trying to access upload.builds[0].build leads to an IndexError | |
| [03:45] <wgrant> StevenK: Sounds like something's creating a PUB without using the method that knows to invalidate stuff | |
| [03:46] <StevenK> But it uses addBuild, which does the invalidation! | |
| [03:46] <StevenK> def addBuild(self, build): | |
| [03:46] <StevenK> """See `IPackageUpload`.""" | |
| [03:46] <StevenK> del get_property_cache(self).builds | |
| [03:46] <wgrant> It's probably clearing the cache too early | |
| [03:48] <StevenK> We should delay clearing the property cache? | |
| [03:49] <wgrant> Clear the cache once the relevant change has been made | |
| [03:49] <wgrant> Otherwise the cache may be recalculated with the old data | |
| [03:49] <StevenK> Then all three of the methods are wrong | |
| [03:49] <wgrant> Lots of code is wrong | |
| [03:50] <wgrant> Most code is wrong | |
| [03:50] <StevenK> Oh, they used to del get_property_cache, return, the searchable_{name,version}s stuff is now in the middle | |
| [03:55] <StevenK> wgrant: I moved the del to just before the return, but it still dies. Guess I need to create the PUB, delete the property cache and then return | |
| [03:57] <wgrant> StevenK: Right, that's what I meant. | |
| [03:58] <wgrant> It's not necessarily safe to clear the cache before you've made the change | |
| [03:58] <wgrant> Because some operation (eg. accessing a protected attribute) may cause the cache to be recalculated | |
| [03:58] <wgrant> At any time | |
| [03:58] <StevenK> print upload.builds[0].build | |
| [03:58] <StevenK> IndexError: list index out of range | |
| [03:58] <StevenK> :-( | |
| [04:06] <StevenK> Do not get it. We create the upload in the factory, create a BPB and a BPR, add it to the PU, where we destroy the cached property, and then return it, and the test says upload.builds is [] | |
| [04:09] <wgrant> Give me a branch :) | |
| [04:09] <wgrant> Or diff | |
| [04:10] <StevenK> wgrant: http://pastebin.ubuntu.com/1453948/ | |
| [04:18] <wgrant> StevenK: Looking | |
| [04:19] <wgrant> Hm | |
| [04:19] <wgrant> StevenK: I wonder if it's not flushing properly | |
| [04:22] <StevenK> wgrant: I was thinking about that -- something that is more aggressive about caching for tests | |
| === tumbleweed_ is now known as tumbleweed | |
| [04:26] <wgrant> An explicit flush fixes it | |
| [04:26] <wgrant> Odd | |
| [04:26] <StevenK> wgrant: As in a store flush? | |
| [04:27] <wgrant> Yes | |
| [04:28] <wgrant> It looks like the SQLMultipleJoin isn't causing a flush | |
| [04:28] <StevenK> Shall I rewrite them into properties that do a IStore.find() ? | |
| [04:28] <wgrant> No | |
| [04:28] <StevenK> Since SQLMultipleJoin annoys me | |
| [04:28] <wgrant> We should work out why it's not working | |
| === broder__ is now known as broder | |
| [04:30] <wgrant> Oh | |
| [04:30] <wgrant> of course | |
| [04:30] <wgrant> checkPermission is wrapped in @block_implicit_flushes | |
| === broder is now known as broder___ | |
| [04:31] <wgrant> I'd explicitly flush before invalidating the cache in each case | |
| === broder___ is now known as broder | |
| [04:31] <StevenK> Right | |
| [04:33] <StevenK> Ah ha, excellent | |
| [04:34] <StevenK> wgrant: Shall I change that print to a assert just to check that this doesn't bite again? | |
| [04:34] <wgrant> StevenK: No | |
| [04:34] <wgrant> Because it will crash if it fails | |
| [04:34] <wgrant> Already | |
| [04:34] <wgrant> Won't it? | |
| [04:34] <StevenK> No, because I stopped creating a BPR | |
| [04:35] <StevenK> And then the method just iterates over builds, which won't care if it's empty | |
| [04:35] <wgrant> Ah | |
| [04:35] <StevenK> So I can revert the change to create another BPR, which I think is silly, but does test that builds is usable, or an assert | |
| [04:41] <StevenK> Haha, one test depends on the second BPR | |
| [04:41] <StevenK> Eh, back it goes | |
| [04:46] <StevenK> wgrant: So you'd like another test to check query counts? | |
| [04:49] <wgrant> Please | |
| [04:49] <StevenK> wgrant: For IDistroSeries.getPackageUploads() via the Webservice or what? | |
| [04:50] <wgrant> That's what I'd do | |
| [04:51] <wgrant> Given that it's going to be lazr.restful triggering the launchpad.LimitedView checks | |
| [05:04] <StevenK> wgrant: http://pastebin.ubuntu.com/1453995/ | |
| [05:09] <wgrant> StevenK: What are those two adjacent SPPH queries? | |
| [05:10] <StevenK> Identical. Odd. | |
| [05:12] * StevenK tries to work out the backtrace | |
| [05:19] <StevenK> wgrant: Do not get it | |
| [05:20] <StevenK> Also not helped by the backtrace being on one line | |
| [05:36] <StevenK> Gah | |
| [05:36] <StevenK> Can't even convert it to something readable | |
| [08:25] <stub> When does patch-2209-40-3.sql get applied? I merged db-devel when I shouldn't have | |
