gouthamrah, old friend15:34
jgrosso:)15:34
jgrossoany target-milestone15:35
gouthamrit's a wishlist item, we haven't gotten anyone to fix this regression for us for the past few releases15:36
gouthamrhowever, we have been fixing doc mistakes manually. so this is tech debt15:36
tbarronit's too bad we don't have another intern slot, this would be a good project.15:36
tbarronunfort. we all have pretty full plates.15:36
jgrossook I saw importance high I will change to wish-list15:37
gouthamrcinder adopted a config-table sphinx extension, smcginnis did a chain of patches iirc; so there's some material we can read/adopt if we like it15:37
tbarronI can't volunteer to take this one right now w/o letting other commitments slide.15:37
tbarronjgrosso: but it's good to bring it up from time to time, maybe someone will get some cycles or inspiration15:38
jgrossotbarron: sounds good15:38
jgrossothat is all I have for today15:38
tbarronjgrosso: thanks15:38
gouthamrwe do generate the config reference from code, but this one is to automatically build tables like this: https://docs.openstack.org/manila/latest/configuration/shared-file-systems/config-options.html15:38

priteauI've started a spec about this topic. It's still early, I mostly described the problem, use cases, and suggested solutions16:08
priteau#link https://review.opendev.org/#/c/663394/1/doc/source/specs/train/flexible-reservation-usage-enforcement.rst16:08
priteauIt would be nice to get your input on it to make sure we are on the same page16:09
priteauIf we agree on the approach, next step will be to draft the API schema16:09
diurnalistthanks priteau, i will have a look16:11
*** ttsiouts has quit IRC16:12
*** whoami-rajat has joined #openstack-meeting-alt16:12
priteauYou're the main Blazar users so your input is most appreciated ;-)16:13
jakecollDo you have an example of a policy web service blazar would be querying?16:14
priteauNot yet, that's the next step in writing the spec. But I assume it could be similar to the way the usage enforcement module in Chameleon's fork is implemented16:15
priteauCalls on create_lease and update_lease to check if the operation is approved16:16
priteauThe trick is which info needs to be passed so that the service can make a good decision16:16
priteauWe can discuss more the interaction between the services once I have a strawman16:19
*** iyamahat has quit IRC16:20
priteauAnything else you want to add on this topic?16:21
diurnalistnot from me, i imagine discussion can move to that review16:21
priteauyes16:21
priteau#topic Upstream contributions16:22
*** openstack changes topic to "Upstream contributions (Meeting topic: blazar)"16:22
priteauI wanted to talk about other features or bug fixes that might be in Chameleon's Blazar and would make sense upstream.16:23
priteauIIRC there are several:16:23
priteau- Network segment reservation. It's on my TODO list to write the spec, I will ask you to review and once approved we can push upstream Chameleon's code for it16:24
priteau- the randomness in the node selection16:25
priteauI don't remember where but I had left a comment saying that the randomness could be made configurable as it is in the placement API16:25
priteau#link https://github.com/ChameleonCloud/blazar/pull/5#issuecomment-42246542716:26
priteau- the heat integration would need to be spec'ed, personally I am not yet convinced if this is the right approach16:27
priteau- blazar-dashboard enhancements (including calendar)16:28
jakecollyea, neither is Zane over on the Heat team16:28
priteauWhere did you have this discussion?16:29
*** enriquetaso has quit IRC16:29
jakecollI submitted a storyboard and code for review16:30
jakecollHe just said he wasn't sure if stack initialization was the right approach.16:31
priteauI had missed it, I was looking for contributions using your uchicago address16:31
jakecollIt should be under my gmail since I already had an Ubuntu One account16:32

jakecollyep, those the ones16:34
priteauLast one is pure Heat, not linked to Blazar at all.16:35
*** iyamahat has joined #openstack-meeting-alt16:36
priteauI am sure I forgot many bug fixes in the list above. It would be good to figure out what is left to push upstream. I think I had a document at some point but it must be out of date.16:36
priteauIs there any other feature that would make sense to upstream?16:39
jakecollI cut a stein branch a few weeks ago. Added more lease info to allocations api.16:39
jakecollShould help us ease off db reliance in blazar-dashboard16:40
diurnalistwe also have a patch to allow running an operator-defined script before a lease ends. we use it to send notification emails16:40
jakecollWhat is the actual timeline on Train?16:40
diurnalisti'm not sure about this one. the use-case is good, but it's a bit difficult to integrate with (a) containers and (b) various mail idiosynchracies16:41
priteaudiurnalist: I thought again about this feature. I think this would be better implemented using notifications16:41
diurnalist*idiosyncrasies - can never spell that right16:41
priteauWhen enabled, Blazar already sends notifications on before_end_lease events16:41
diurnalistso you mean listening on the message bus?16:42
priteauYou could have a completely separate service listening for them and generating the emails16:42
diurnalistyes. another thing though is, usually sending a mail is something best done quite a ways before the lease ends. the "normal" use of before_end is to do something immediately before ending. like taking a snapshot16:42
diurnalistso i'm not too sure. long story short, we have this patch but idk how it fits upstream16:43
priteauWe could add support for multiple before_end_lease events with configurable timers16:45
priteauOne for emails 48h before, one for snapshot 30 minutes before16:45
priteauI think that would be a more flexible approach, including for users if we eventually have more before_end actions16:49

priteauI'll open a bug on Launchpad to remember about the multiple before_end events16:50
