I understand 21:05:24 in dublin, we agreed that the feature/s3api merge would be to only bring in the existing swift3 codebase. all tests will pass and it will work if enabled, but no changes to any architecture or enabling anything by default 21:05:26 talking on trello board 21:05:34 is that still the same plan you're working towards? 21:06:33 i'm thinking, I put the items that we don't want to develop on feature/s3api immediately (i.e. will do after merged to the master) in the future work groups 21:06:42 good 21:06:51 so please checkout if my collection is correct (or not) 21:06:59 notmyname: yes 21:07:29 so the remaining tasks in the backlog/in-progress are what I'd like to resolve for a monce. 21:07:33 month. 21:07:53 ok. it doesn't look like a lot. (and that's good) 21:08:01 that is a summary for the updates 21:08:10 and then, one thing I'd like to get your help 21:08:34 we're getting closer to when feature/deep will land something in master, so the biggest concern will be to make sure those two merges don't happen at the same time 21:08:44 I had 3 outstanding patches for the work now 21:09:04 oic, nice to hear for feature/deep 21:09:08 the patches are 21:09:11 https://review.openstack.org/#/c/552853/ 21:09:11 patch 552853 - swift (feature/s3api) - Update S3api Docs 21:09:26 https://review.openstack.org/#/c/552854/ 21:09:26 patch 552854 - swift (feature/s3api) - Cleanup swift/common/middleware/s3api/test dir 21:09:53 https://review.openstack.org/#/c/551273/ 21:09:53 patch 551273 - swift (feature/s3api) - Avoid global CONF instance 21:10:13 in particular, I'd like to hear advice on the first one (docs) 21:10:21 what's needed there. 21:10:31 ok 21:10:37 I'll take a look 21:10:56 because probably I know everything other than you all about s3api so I may be missing something. 21:11:12 anything else for an update on this work? 21:11:33 if you don't have any questions :) 21:11:48 nothing 21:12:00 kota_: thanks for driving this work! 21:12:10 +100! 21:12:29 #topic add force_auth_retry mode to python-swiftclient when got errors other than 401 21:12:36 https://review.openstack.org/#/c/551956/ 21:12:37 patch 551956 - python-swiftclient - Add force auth retry mode in swiftclient 21:12:41 kota_: this is your topic too 21:13:00 kota_: what is the question we need to answer in this meeting? 21:13:06 ah, short answer on the conflict with feature/deep, i don't think it's not so big matter because basically s3api touches on only middleware or docs. 21:13:10 yeah 21:13:17 the python-client thing 21:13:45 I'd like to hear the feels it's better to have on swift community upstream 21:13:53 let me describe short history of that. 21:14:02 mainly described at the commit message. 21:14:52 the problem I'd like to resolve is the case using sort of reverse proxy(e.g. nginx/Load balancer) between the python-swiftclient - swift-proxy-server. 21:15:44 the reverse proxy can close the connected socket when it gets error response from swift-proxy. 21:16:34 and it causes broken pipe (socket error, EPIPE) in the python-swiftclient, if python-swift client is still attempts to put the http body (e.g. put object) 21:17:15 so the proxy is hiding the 401 response by simply closing the socket, and swiftclient doesn't reauth because it never saw the 401 21:17:33 the best way to resolve it, is supporting expext: 100-continue header in the client but it seems to be hard to get in immediately . 21:17:42 notmyname: yes 21:17:48 i think the 401 gets sent, *but the client hasn't read it* 21:18:04 timburke: correct 21:18:32 but i don't think we have the way to read it after the socket was closed... right? 21:18:59 so the proposal on the patch is to add a mode to force the re-auth on any errors. 21:19:22 i know, it's not straight forward to resolve the problem, just mitigation. 21:19:23 not sure -- i haven't had a chance to play around with it... 21:19:24 ok, that seems reasonable 21:19:46 sounds like it was a fun issue to debug 21:19:52 "fun" 21:20:01 clayg already has a +2 on it 21:20:07 so my point is that. 21:20:08 heck yeah! 21:20:21 thanks clayg! 21:20:58 matt left an earlier review, but he's not hear right now. perhaps he'll be able to pick it up again and give another review? 21:21:15 maybe 21:21:48 I'll poke him later again 21:21:51 I said something to him in -swift about it, too 21:21:55 kota_: thanks 21:22:21 ok, on the theme of bugs, I'm going to skip around just briefly... bear with me kei-ichi 21:22:40 #topic multiple or bad url quoting 21:22:49 https://bugs.launchpad.net/swift/+bug/1755554 21:22:50 Launchpad bug 1755554 in OpenStack Object Storage (swift) "Percent signs in object names cause trouble for versioned_writes" [High,Confirmed] 21:22:50 np 21:22:57 we found this bug yesterday 21:23:22 timburke gave a good summary of the issue 21:23:43 "we suck at URL quoting" 21:23:56 🤣 21:23:57 I wanted to bring it up in the meeting because (1) I'd love to find someone who will volunteer to work on a fix and (2) ask if it should be "critical" instead of "high" 21:24:03 timburke: perfect summary :-) 21:24:28 idk, it's not a regression - it's just always been this way hasn't it? 21:24:55 I don't know. perhaps the rewrite to versioned_middleware broke it? 21:25:29 i still have torgomatic's https://gist.github.com/smerritt/ca5a6701d46c55b43059e4d0e302c2f9 up in a tab... in case i ever find myself with a surplus of time... 21:25:56 the big bad (imo) is that versioning flat out *doesn't work* for some objects 21:26:17 you think you've got versioning enabled, go overwrite an object *and it's gone* 21:26:30 not great 21:26:31 too bad 21:26:32 yeah, that's where I get the question of "critical" 21:27:28 really, if we've got someone working on a patch, the difference between high and critical is holding a release for the critical patch to land. and, to be fair, we don't have a release scheduled soon (just lots of other stuff going on) 21:28:34 so the most important question is this: "can someone volunteer to work on a patch for this bug?" 21:29:07 (please, not everyone at once) 21:29:20 👃👈 21:29:29 i might be able to? but almost certainly not this week 21:29:55 me too, it might be able to. 21:30:09 ok. timburke and kota_, thank you 21:30:37 I'll leave it on the agenda for next week, and we'll see if you've had a chance to look at it 21:30:55 #topic slogging 21:31:00 last topic on the agenda 21:31:03 This is mine. 21:31:10 I would like to confirm that which channel should I use to inform slogging event. 21:31:18 Firstly I plan to create new channel named "#openstack-slogging" and sent patch to project-config repository. --> plan-1 21:31:19 Now infra-team give me a comment that is it really mandatory.(send to swift channel --> plan-2) 21:31:23 if you remember from dublin, we talked with kei-ichi about him moving slogging into an openstack namespace 21:31:33 yes 21:32:23 this is my patch to openstack-infra/project-config https://review.openstack.org/552282 21:32:24 patch 552282 - openstack-infra/project-config - Add slogging projects 21:32:31 here's a question to everyone: would anyone object to having slogging patches reported in the #openstack-swift channel? this implies that discussion about those patches may also happen in the -swift channel 21:32:42 no 21:32:53 no objection I mean 21:33:03 I think, this time slogging will be created as separate repository from swift so I think IRC channel should also be separated. (means plan-1) 21:33:37 I would like to hear about this point to swift team prior to fixing patch. 21:33:48 kei-ichi: I believe the -infra team has concerns about the number of channels that they manage and that are supported by the IRC server and that's why the like to consolidate when possible 21:34:04 eg a bot can only be in a certain number of channels at a time 21:34:08 I understood. 21:34:25 i think it makes sense to have it in the -swift channel 21:34:33 it seems like the target audiences would be similar, as well. i know we've gotten a fair number of swift3 questions in #openstack-swift, despite there being a separate #swift3 channel 21:35:04 I agree that slogging should be separate from swift in governance (eg not relying on swift-core for patches or releases), but I would almost prefer to have slogging updates in -swift instead of separate 21:35:09 timburke: +1 21:35:13 ...base on exactly what timburke just said 21:35:46 OK, so same as liberasurecode, can I use -swift channel to inform ? 21:35:48 which means we should shutdown swift3 channel at some point?? 21:35:55 tdasilva: +1 21:36:02 tdasilva: we should do that anyway because of feature/s3api 21:36:08 right 21:36:10 tdasilva: after, we get merged feature/s3api 21:36:18 kei-ichi: are you ok with having your updates go to -swift? 21:36:21 * tdasilva has considered shutting down swiftonfile too 21:36:29 tdasilva: there's a swiftonfile? ;-) 21:36:30 i think more traffic in openstack-swift is generally a good thing - I don't mind a variety of topics. 21:36:35 clayg: yes!! 21:36:38 yes, patch is really simple, so it is easy to fix. 21:36:51 I don't expect slogging to have enough activity to overwhelm us in -swift 21:37:28 I think so. So I'll fix patch so that information will be sent to -swift channel 21:37:42 would that be okay? 21:37:46 kei-ichi: so what I'm hearing from everyone, not only are we happy to see you work on a project related to swift so that more people can use it, we want you to do it with us! 21:37:52 kei-ichi: yes! 21:38:07 Thank you notmyname ! 21:38:16 #topic open discussion 21:38:21 anything else to cover this week? 21:39:03 I take that as a "no" 21:39:18 i've said it repeatedly already, but just wanted to give another thank you to acoles for getting sharding probe tests going in zuul v3! 21:39:30 thank you everyone for your work on swift 21:39:35 #endmeeting
