17:24:11 melwitt ok, so repeated was not officially supported < 1.39. sorry I had missed that
17:24:44 gmann yeah, it was always nor documented neither we knew how it work until gibi found it?
17:24:47 gibi melwitt: <1.39 there was not defined behavior for repeat
17:25:08 gibi the code happened to pares the last repetition
17:25:12 gibi parse
17:25:15 gibi and ignore the rest
17:25:49 melwitt gotcha.. thanks

17:29:23 melwitt dansmith, bauzas: just a fyi, oslo.limit got a new release so I cleaned up the unified limits set to use it and removed the haxx
17:30:12 gibi sean-k-mooney, gmann, melwitt, efried: I restored the patch series of microversion 1.39 not to change the behavior of the repeated required param handling in < 1.39 microversion https://review.opendev.org/q/topic:any-traits-support
17:30:42 gibi so < 1.39 if the required param is repeated only the _last_ instance is parsed a rest is ignored
17:30:46 bauzas melwitt: cool, as I said, you're my next priority once I'm done with trying to work on Tempest :p
17:31:40 melwitt k :)
17:34:04 dansmith melwitt: nice

19:56:23 melwitt chateaulav: it show it's in merge conflict, should just need a rebase
19:57:01 melwitt *shows
19:57:31 chateaulav melwitt: yeah, tried, i think i got it. had to hard reset the branch. gonna add all the changes back and see if it resolves now

#openstack-nova - 2022-02-01
00:16:52 gmann gibi: ack
02:30:43 gmann gibi: sean-k-mooney[m] melwitt just tested that nova API query param also allow duplicate query param and take latest one. I remember somewhere we convert that to python dict that is why the last one is considered.
02:31:13 melwitt well that's fun
02:31:52 sean-k-mooney[m] there are some query parmaters that we all to be repeated like field that can be used to generate an array
02:32:19 sean-k-mooney[m] but unless we expressly document that as a supported usecase in teh api ref using it should be considerd a bug
02:32:49 sean-k-mooney[m] if its not in the api-ref or in the orginal spec it is not part of the public api contract
02:33:16 sean-k-mooney[m] gmann which nova api query parmater were you testing?
02:33:26 gmann list server
02:33:40 gmann limit filter
02:37:54 sean-k-mooney[m] no user should ever depend on the last instance of a parmater being used in the nova api we are free to change that at any point unless there is api documenation that expressless states that for any given parmater.
02:39:39 sean-k-mooney[m] put another way i do not think we should ever accpeat a bug if we change that behaivor without a microversion as it is an out of contract use fo the api and governed by the micorversion contract as a result
02:48:42 sean-k-mooney[m] ack i would consider depending on that behavior to be unsupported, https://docs.openstack.org/api-ref/compute/?expanded=list-servers-detail#list-servers does not declare you are allowed to repate the args as part of the filter support
02:49:46 sean-k-mooney[m] we should be retrunnign a 400 but we are not validateing that. if we change the behavior in the future it should not require a microversion as this is not part of the api specification today
02:52:35 gmann gibi: melwitt sean-k-mooney[m] we validate it by converting it to set which will add multiple passed value in query param - https://github.com/openstack/nova/blob/master/nova/api/validation/__init__.py#L176
02:52:41 gmann which is good.
02:52:54 gmann but here this guy just pick latest one https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/servers.py#L179
02:53:34 gmann sean-k-mooney[m]: additional param in query param was also not written behavior in api-ref but we change that with microversion so that we do not break users
02:54:13 sean-k-mooney[m] i really think this raised to the level of a v3 api change if we dont reject it without a microversion change
02:54:34 sean-k-mooney[m] i really dont think this is something we shoudl require a microversion change for
02:54:34 gmann I consider API usage as what code allow than what is there in api-ref. api-ref are not complete set of 'how not to use' its just 'how to use'
02:55:20 sean-k-mooney[m] to me the is a unaccpable burden of mantaince to contineu to supprot. the api is not defiend by the implemantion its defiend by the specification and this is not part of the specificaiont
02:55:21 gmann it is like we allowed our API to be used that wrong way and for many users it was working that as successful case.
02:55:56 gmann sean-k-mooney[m]: not our API :) api -ref was written based on what implementation was.
02:56:33 gmann we try to match that but if api-ref mention something and code does not behave that way then yes we consider as bug
02:57:03 gmann but if api-ref which is not complete does not mention anything does not mean code is wrong and we can change that without versioning
02:57:34 gmann in past we used to document that as known bug/behavior and fix in new microversion
02:57:51 sean-k-mooney[m] i disagree if the api and spec for the feature do not refernce the behaivor it is not part of the public contract
02:58:32 sean-k-mooney[m] i dont think we should leak the impleation into the public contract
02:58:40 gmann it should if we have designed our API that way but it is not. it was always what implementation was and that is being used.
02:58:52 sean-k-mooney[m] we did design our apis that way
02:59:02 sean-k-mooney[m] its why we require a spec for all api changes
02:59:40 sean-k-mooney[m] the really issue i guess is some fo the apis are form pre microversion and did not have a spec
02:59:59 gmann that is fine. I am saying for old and existing behavior. that is why microversion was introduced. for new APis/feature I agree as per spec driven.
03:00:01 sean-k-mooney[m] for example the regex support today in list servers is directly tied to the db you use
03:00:54 sean-k-mooney[m] i really think it would reduce the quality of our software to not fix what in my mind is broken validation code
03:01:04 gmann even rejecting unknown and invalid query param (which we ignored silently in code) was also changed with microversion so that we do not break users
03:01:48 gmann I am not saying that is good and should not be fixed. it should be but with microversion
03:03:14 sean-k-mooney[m] i guess with my downstream hat on i would be much less willing to supprot this. upstream we might be able to allow invalid input but form a downstream perspecitive i dont think i would accpete this form a customer bug. the api contract exits for a reason and not enforcing that contract exposes us to suppporting thing we never intended that is harmful to the healt of the product in my view
03:04:29 gmann my 1 month old saying to stop arguing on APIs :) its time to feed him. :P
03:04:41 sean-k-mooney[m] :)
03:04:52 sean-k-mooney[m] go do that
03:05:35 sean-k-mooney[m] but if we cant fix this without a microverion or validation middleware i think we have to reconsider raising the min microversion to fix this
08:04:56 gibi the more I think about API contract the more I feel that we are on the wrong path. Saying that we should not change the behavior of our APIs without a microversion could be abused to the extent that forbid any kind of change of the implementation behind the API.
08:06:52 gibi say we have a placement sql bug that breaks resource acconting today in a certain situation. As this is how the service works today one can say that a client might depend on the buggy behavior of the resource accounting hence we cannot fix the accounting outside of a microversion so placement servers out on the field will have the buggy behavior until everybody upgrades to future mastyer
08:07:17 gibi so imagine two customers
08:07:41 gibi i) customer depending on the buggy behavior and getting a stable bugfix would break their usage of placement
08:07:57 gibi ii) customer is facing the buggy behavior and their system is broken until the buggy behavior is removed
08:08:22 gibi clearly we cannot support both customer
08:08:54 gibi so it boils down to which customer we would like to support more? i) who depends on a bug ii) who are hit by the same bug
08:36:45 bauzas gibi: agreed with you
08:37:08 bauzas I wonder why we should support the i) customer if they already have an issue
08:38:26 gibi i) has no issue it is happy who the api behaves today
08:38:55 gibi s/who/how/
08:42:37 bauzas gibi: well, I'm not sure this customer knows about the behaviour actually
08:42:52 bauzas maybe he's just happy because it works
08:44:40 gibi yeah, it can be accidental use
08:51:18 bauzas just a thought, we always said to avoid as much as possible to directly pass a placement request by flavors
