abhishekkhi14:04
abhishekkSo we are having Milestone release 2 this weeks14:05
abhishekkthanks to Brian and Sean for reviewing the patches14:05
rosmaita:)14:05
abhishekkWe have lined up glance-store v 1.0.0. lined up14:06
abhishekk#link https://review.opendev.org/#/c/672627/114:06
abhishekkabove is the release patch for the store14:06
abhishekkjokke_, and rosmaita kindly have a look14:06
abhishekk#link https://etherpad.openstack.org/p/Glance-Train-MileStone-2-Release-Plan14:06
jokke_will do14:07
abhishekkThis etherpad will help us to track down the glance changes which are essential before M2 release14:07
rosmaitaso do we expect glance_store 1.0.0 to break anything?14:07
abhishekkThis is on release front, any word jokke_ ?14:07
abhishekkrosmaita, I don't think so14:07
rosmaitalooks like it def breaks our functional tests14:07
rosmaitalooks like the unit tests are ok14:08
jokke_rosmaita: we are expecting the backend->store breaking so we will need to get that change in glance asap14:08
rosmaitayeah, but my point is when we release, upper-constraints will be changed14:08
abhishekkrosmaita, are you looking at tips jobs?14:08
rosmaitayes14:08
rosmaitahttps://review.opendev.org/#/c/671707/314:08
abhishekkthose were failed because in morning the git or opendev.org was down for couple of hours14:09
rosmaitatake a look at the experimental results on that14:09
abhishekkoops14:09
rosmaitahttp://logs.openstack.org/07/671707/3/experimental/glance-tox-functional-glance_store-tips/2651b8a/testr_results.html.gz14:09
jokke_thanks rosmaita for pointing it out, we need to check that before we pull the trigger on the release14:11
rosmaitanp, will just take some careful coordination14:11
jokke_yup, the naming change I know will break stuff but haven't been looking for other things yet14:11
jokke_abhishekk: you had something on the periodic jobs as well14:12
abhishekkjokke_, yeah14:13
abhishekkwe have 3-4 failures due to parser error during this weel14:13
abhishekks/weel/seek14:13
abhishekkopps14:13
jokke_:P14:13
abhishekkLooks like I need some sleep14:13
jokke_So any idea what's triggering those. Is it still the same issue or has something else changed?14:13
abhishekkno still the same issue14:14
abhishekklarge size of log messages are causing it14:14
jokke_have we increased logging somewhere?14:14
abhishekknope14:14
rosmaitajokke: are you going to -1 the glance_store release patch?14:14
abhishekkrosmaita, any Idea how can I locally test this failures14:16
jokke_just did14:16
abhishekkI guess I need to copy glance-store in virtual environment and then run the tests against those, right?14:16
jokke_abhishekk: locally you would nbeed to change the requirements to use the git link instead of just package name iirc14:17
abhishekkjokke_, ack14:17
rosmaitaabhishekk: either that, or we skip-test the failures14:17
rosmaitamerge that14:17
rosmaitarelease glance_store14:17
rosmaitathen you fix the failures14:17
rosmaitawe remove the skip-test14:18
abhishekkmake sense14:18
rosmaitaand hooray14:18
rosmaitajokke_: that sound ok?14:18
jokke_lets just check what is blowing first to make sure we don't need to release 1.0.1 tomorrow just because it was something we had to fix in glance_store14:18
abhishekkI will give it a try tonight14:18
jokke_if it's just the glance stuff we know needs to be changed, skipping the tests or queueing the fix first thing to merge would be fine14:19
jokke_I'll have a look on the logs after the meeting14:19
davee_abhishekk: after you get some sleep I hope14:19
abhishekkdavee_, If I sleep now in my dream I will see broken gate :D14:20
rosmaitasounds good ... do we have a deadline to release glance_store ?14:20
davee_hmm, I have dreamed and written code in my sleep that worked the next day14:20
jokke_rosmaita: kind of today, if it needs to be pushed because it's broken then we push it to next week14:20
abhishekk:D14:21
jokke_ok, lets move on14:21
jokke_#topic wording on multi-store documentation14:21
*** openstack changes topic to "wording on multi-store documentation (Meeting topic: glance)"14:22
jokke_I just wanted to highlight that I think we need to be stronger than the current "not recommend" on using same path for task_work dir, staging and possible filestore14:23
*** bobh has joined #openstack-meeting-414:23
jokke_#link https://review.opendev.org/#/c/611253/16/doc/source/admin/multistores.rst14:23
abhishekkrosmaita, ^^^^ you are the one who can propose this :D14:23
rosmaitaok14:24
jokke_my reasoning is that _if_ someone uses the same path, it will give same prefix for multiple store id's and might end up to the autodiscovery tool assigning "os_glance_*" store id to the image14:24
rosmaitayeah, that will definitely happen14:25
abhishekkif someone uses same path for staging and fs store then it will be mess14:25
jokke_there should not be often those cases, but I don't like the idea of possibility14:25
rosmaitawe probably need to put some kind of checking in the code14:25
rosmaita(eventually)14:25
jokke_so "not support" or blunt "Don't do it!" would be mnore of my liking :)14:25
*** k_mouza has quit IRC14:25
rosmaitayes, a warning box and do not do it14:26
abhishekksounds good14:26
jokke_thanks, that was all from me ... just wanted to take couple of mins for brainstorming how we word that doc14:27
abhishekkit will be kind of difficult to add that check, and if we want to add that check that needs to be added in store14:27
jokke_rosmaita: if you have something in mind, and have time to push new rev, that would be amazing14:27
rosmaitayeah, i will push somethinig in a few min14:27
jokke_<314:27
jokke_#topic open discussion14:27
*** openstack changes topic to "open discussion (Meeting topic: glance)"14:27
rosmaitaabhishekk: yes, probably when the map is populated14:27
rosmaitai will file a bug so we dont forget14:28
abhishekkrosmaita, right14:28
rosmaitaactually, should probably be a known issue in the glance_store release notes?14:28
rosmaitai mean, additionally?14:29
abhishekkrosmaita, ok for me14:29
jokke__if_ we need to change something else before the release. It's really glance issue, not glance_store issue 'though14:29
rosmaitawell, i guess that's right14:30
rosmaitaanyway, we are the only consumer of glance_store multibackend right now14:30
jokke_yup14:30
rosmaitai will add it to that glance releasenote on https://review.opendev.org/#/c/611253/16 , though14:31
*** gcheresh has quit IRC14:31
jokke_that sounds like a good plan14:31
rosmaitacool14:31
*** k_mouza has joined #openstack-meeting-414:31
abhishekkgreat14:32
jokke_we can always remove it from reno if we come up with bulletproof fix before actual release14:32
rosmaitaright14:32
rosmaitawe may have to do it on the glance side before we create the store14:33
rosmaitawe can crawl the config and check14:33
abhishekkwe can do it in glance after store is initialized14:34
jokke_or we can just prevent the func using anything starting with os_glance_14:34
rosmaitaok, well, we are not short on ideas14:35
jokke_but it doesn't need to be today's decision. Lets try to get the 1.0.0 release out and think it after so we get something out there for people to test14:35
rosmaitai'll file the bug for glance and not the store14:35
jokke_++14:35
jokke_anything else?14:37
zhengMaHi, I have purposed a spec  lite: - Add 'compressed' option to container_format - https://review.opendev.org/#/c/670454/14:37
zhengMaIt has been discussed on this meeting last week and I'm expecting more reviews14:37
abhishekkI found the problem in functional failures14:37
abhishekkif we add skip test and then merge https://review.opendev.org/#/c/658962 this patch then it will solve the issue14:38
abhishekkhttps://review.opendev.org/#/c/658962/6/glance/api/v2/images.py look at line no #1033 to #103714:38
rosmaitaabhishekk: cool!14:39
jokke_so that is glance_side failure we're queued to fix anyways?14:39
abhishekkyes14:39
jokke_cool so not blocking the release then14:40
jokke_was there anything else we were not aware of?14:40
abhishekknope14:41
rosmaitazhengMa: i think your spec looks good, did LiangFang say in the cinder meeting yesterday that you will test to see what happens if you try to boot an image with container_format == compressed in nova?14:41
abhishekkso should I go ahead and add a patch for skipping the tests?14:41
jokke_great, will swap my -1 to +1 on the release patch then14:41
abhishekkI guess it will not break the release at it will just runs the unit tests14:41
jokke_zhengMa: yes, sorry I've been on PTO and just catching up and bit tangled with the release. I promise I will read through that spec for you14:42
zhengMajokke_: thank you !14:42
rosmaitayeah, what we have to watch for is as soon as upper-constraints is updated, glance will block the gate until https://review.opendev.org/#/c/658962 is merged14:42
jokke_mhm14:42
zhengMarosmaita: yes, he told me it, and we have been testing it14:42
jokke_lets propose skip to that test and merge it right away14:43
rosmaitazhengMa: great!14:43
abhishekkjokke_, ack14:43
rosmaitajokke_: sounds good14:43
jokke_so we have bit time to go through that patch and remove the skip in it14:43
rosmaitajokke_: ++14:43
*** yamamoto has joined #openstack-meeting-414:43
abhishekkwill push that patch in some time14:45
jokke_great, I'll see that having +W before swapping my release -1 to +114:45
jokke_anything else?14:45
davee_I have nothing else14:46
abhishekkwe have @skip_if_disbaled decorator14:46
abhishekkhow about moving those tests on blacklisted text file created by rosmaita14:46
jokke_there should be skip decorator you can give bug or comment that shows up on the test run14:47
zhengMarosmaita: nova seems unable to handle this new format now14:47
rosmaitai think there's an unconditional skip decorator too14:47
rosmaitazhengMa: what happens? what is the response from nova?14:47
jokke_just put message on it that it was disabled for working around 1.0.0 release14:47
abhishekkam not able to found it anywhere14:48
zhengMarosmaita: well currently no proper response and it just failed accessing the VM's console14:48
*** k_mouza has quit IRC14:48
jokke_https://docs.openstack.org/tempest/latest/library/decorators.html14:49
rosmaitazhengMa: ok, we will need to open a discussion with nova about this14:49
zhengMarosmaita: right in nova, thanks14:49
jokke_we can use @skip_because if we file a bug for it14:50
abhishekkthere is skipTest14:50
jokke_that should work14:50
jokke_just put todo or fixme comment on it14:50
rosmaitazhengMa: what kind of image did you use?14:50
abhishekkack14:51
jokke_zhengMa: I don't think we want to have format that nova and cinder can't handle, so we likely need to address that with nova first like rosmaita said14:51
zhengMarosmaita: container_format: compressed disk_format: either raw or others14:52
rosmaitajokke_: cinder will be able to handle this14:52
jokke_rosmaita: (nova and cider) condition fails if either fails :D14:52
jokke_just generalizing for further discussion that I would feel the same with cinder failing14:53
rosmaitazhengMa: the real test would be to take a raw image that does boot correctly with Nova (a VM you can connect to), and then upload a gzipped version of that raw image, and see what happens when you boot from nova14:53
*** yamamoto has quit IRC14:53
rosmaitajokke_: yes, we just want to make sure that nova either can handle the format, or knows to reject it as unknown container_format14:54
jokke_yup14:54
jokke_getting something meaningful out of it14:54
zhengMarosmaita: that is what we have done, and nova failed while directly booting from that gzipped image14:54
jokke_and that we have documented the type somewhere not being nova bootable if that's the case14:54
rosmaitazhengMa: ok. and the failure was that the VM booted, but was unusable?14:55
jokke_zhengMa: have you discussed with nova if they are interested to support that?14:55
zhengMajokke_: not yet14:55
* jokke_ sees edge benefit for this14:55
jokke_less bits to move to the edge site14:56
zhengMarosmaita: right! it boots up but unusable14:56
zhengMabecause nova just takes it as the raw image14:56
jokke_zhengMa: yeah ^^ is something that needs to be addressed before we implement this14:56
zhengMaso I think maybe a little patch in nova would address it14:56
*** k_mouza has joined #openstack-meeting-414:57
jokke_I think there is usecases where lots of ops would be happy about this14:57
jokke_lets just do it right :D14:57
zhengMathank you:)14:58
jokke_last 2min14:58
rosmaitazhengMa: can you send a message to the mailing list about this?14:58
rosmaitawe can talk in glance channel after the meeting14:59
zhengMarosmaita: ok!14:59
rosmaitathanks14:59
