13:36:05 sean-k-mooney so ret: ty.DefaultDict[str, int] = collections.defaultdict(lambda: 0) is default initallising a dictionary where the values will be 0
13:37:55 gibi defaultdict takes a callable to produce the default value
13:38:07 gibi sometimes we use int instead of lamba: 0
13:38:10 gibi both produce 0
13:38:56 gibi as int() == 0 as well as lambda: 0() == 0
13:39:32 sean-k-mooney ya its a cleaver solution but also suprisign if you have not seen it before
13:39:54 sean-k-mooney i would have expect to just pass 0 honestly
13:40:06 sean-k-mooney but i can see why that would not be a good patern in general
13:40:17 gibi you cannot pass 0 as that is not a callable
13:40:35 sean-k-mooney if it was a complex object instead of a literall it would be a problem to allow passing the object directly
13:40:42 sean-k-mooney since it would be shared not cloned
13:40:51 sean-k-mooney hence a callable to produce the defualt value
13:40:54 gibi yepp
13:41:02 gibi so we have to pass something that returns 0
13:41:21 gibi both int, and lamba:0 is good for that, but a 0 literal is not
13:41:43 sean-k-mooney yep
13:42:40 sean-k-mooney its more a deficite of the api of the datastucture then anything else. its more flexable however then the claical default approch
13:43:10 sean-k-mooney its just different form how get and set_default work
13:43:43 sean-k-mooney but inline with how sorted or filter works where you provide a key funcion as a callable
13:52:37 nightmare_unreal how can i access clouds.yaml file once it's loaded. Suppose i want to read some values from it . For context i am trying to read placement_api_version
13:53:26 sean-k-mooney there is a lib for it but OSC will automaticlaly do it for vars in the right format
13:54:49 sean-k-mooney its just a yaml file however so in your own code you can jsut read it with the stardard lib
13:55:10 sean-k-mooney i think its in osc-lib
13:56:03 nightmare_unreal i am working on a bug : osc client does not read placement API version variable . variable name placement_api_version
13:56:26 nightmare_unreal so i am trying to figure out where in osc it reads the yaml file
13:57:04 sean-k-mooney its case sensitive and has to be uppercase just an fyi
13:57:11 sean-k-mooney i think
13:57:27 openstackgerrit Lee Yarwood proposed openstack/nova master: docs: Move the LibvirtDistroSupportMatrix wiki page into our docs https://review.opendev.org/c/openstack/nova/+/771981
13:57:29 sean-k-mooney that would be in osc-placement
13:57:32 nightmare_unreal obvious solution that will not be good is to read the config file in osc_placement plugin and look for that value if it's set then good .
13:57:41 lyarwood stephenfin / kashyap ; ^ would you mind reviewing this, still need to add some versions and work out where it should live (if not in our reference docs)
13:58:14 sean-k-mooney nightmare_unreal: https://github.com/openstack/osc-placement/blob/master/osc_placement/plugin.py#L53
13:59:05 sean-k-mooney it uses https://github.com/openstack/osc-lib/blob/ec1b7dda0e6dc1ec614a92e24267d058783ad27f/osc_lib/utils/__init__.py#L134-L144
13:59:15 sean-k-mooney to get the values for the env
13:59:24 nightmare_unreal in clouds.yaml it should be defined like that ? OS_PLACEMENT_API_VERSION but i think there is a file that automatically does that
13:59:29 sean-k-mooney but i think cloud.yaml is expeorted to the evn
13:59:34 nightmare_unreal I see
13:59:58 nightmare_unreal in my head the env is when in cli we explicitly do export OS_BLAH_BLAH
14:00:09 sean-k-mooney yes it is
14:00:11 nightmare_unreal but if it takes clouds.yaml as env
14:00:20 nightmare_unreal then i have to think
14:00:29 sean-k-mooney but i think we extract some paramaters and add them to it
14:00:44 sean-k-mooney i havent looked at this closely but was how i understood it to work
14:01:16 gmann brinzhang_: ack, I will check those in details and see were it is wrong. basically having separate APi controller class should not cause any issue
14:02:14 nightmare_unreal I see. yeah trying to figure it out myself :)
14:03:12 sean-k-mooney so i think this is wher we read the cloud.yaml https://github.com/openstack/osc-lib/blob/ec1b7dda0e6dc1ec614a92e24267d058783ad27f/osc_lib/shell.py#L408-L413
14:03:18 gmann sean-k-mooney: gibi I thikn 2 hr is even more time for that job disbale swift and does not run swift/keystone/slow tests
14:03:39 sean-k-mooney gmann: ya i mentioned the timeout befor ei check the build page
14:03:43 kashyap lyarwood: Hey, will check; sigh, missed the notif here
14:03:45 gmann ohk
14:03:52 sean-k-mooney gmann: it shoudl be fine just a slow node
14:04:01 gmann sean-k-mooney: yeah.
14:04:30 gmann except tripleo jobs almost all our gate are with max 2 hrs job run
14:04:59 sean-k-mooney yep
14:05:02 kashyap lyarwood: Thanks for moving; I think I have a half-done patch for it somewhere; but didn't update it
14:06:16 nightmare_unreal thanks sean-k-mooney , looking :D
14:06:32 sean-k-mooney that delegating to the sdk now
14:09:06 sean-k-mooney nightmare_unreal: this is what does the actul loading i think https://github.com/openstack/openstacksdk/blob/4ce235d36dfa3420534ad1b145cc7c5f7438e8e0/openstack/config/loader.py#L140
14:10:58 nightmare_unreal yeah i think so too, looking
14:14:40 sean-k-mooney nightmare_unreal: regardelss of how its parsed i think this is what you are really looking for https://github.com/openstack/openstacksdk/blob/4ce235d36dfa3420534ad1b145cc7c5f7438e8e0/openstack/config/loader.py#L1057
14:15:17 sean-k-mooney to lookup a value in the config
14:15:46 nightmare_unreal yes exactly , and also to check if the defined key:value in clouds.yaml is read or not
14:15:50 nightmare_unreal thanks
14:16:08 kashyap lyarwood: Do you havea rendered version of it?
14:18:46 kashyap lyarwood: sean-k-mooney: For testing w/ Secure Boot in the Gate ... none of the cloud images are built with EFI partition ... I'm wondering if are allowed to upload new images for testing?
14:19:06 lyarwood kashyap: http://storage.bhs.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_8b1/771981/1/check/openstack-tox-docs/8b1d7c4/docs/reference/libvirt-distro-support-matrix.html
14:19:09 kashyap The short context is: you'd need a disk image with EFI partition in it
14:19:42 kashyap I'm thinking of making a custom template image for testing; is it allowed to upload somewhere via the infra and make use of it?
14:19:55 lyarwood kashyap: we shouldn't need to upload an image into CI, we can just host and reference one that does in a test job
14:20:17 lyarwood kashyap: assuming you're talking about the test instances and not the test hosts
14:20:19 kashyap lyarwood: Ah; okay. I'll find a suitable location to host it, once I prepare it
14:20:33 kashyap lyarwood: Test instance, indeed. I'm talking about a guest
14:20:51 sean-k-mooney kashyap: do you mean the guest image e.g. cirros
14:21:06 lyarwood kashyap: right then there's likely best practice our where we can host it, if it needs to be cached etc but we should be able to drop in a suitable image
14:21:17 lyarwood practice around*
14:21:22 sean-k-mooney we are not ment to pull arbiary blobs down in the jobs
14:21:24 kashyap lyarwood: E.g. this is what a guest image that can do EFI/SB should have, to start with: http://paste.openstack.org/show/801871/
14:21:30 kashyap sean-k-mooney: Yes, guest images indeed.
14:21:39 sean-k-mooney so if we need a special test image we need to have that hostsed/cached by infra
14:21:48 kashyap sean-k-mooney: Okay; I'll check w/ the infra folks.
14:21:55 sean-k-mooney kashyap: are there any test image packaged in distors
14:22:07 sean-k-mooney kashyap: i know we sometimes have isos deistibted by rpms
14:22:09 kashyap No, none do it; most do it via install trees
14:22:15 kashyap sean-k-mooney: For example, see how I test it here: https://kashyapc.fedorapeople.org/Create-a-SecureBoot-enabled-VM.bash
14:23:12 sean-k-mooney what we would praobly want to do is convert that into a diskimage builder element
14:23:28 sean-k-mooney then have nodepool build it for us
14:23:46 sean-k-mooney and cache it on the provieders
14:24:27 lyarwood can the instances pull images from glance in these envs?
14:24:42 lyarwood or swift
14:24:47 lyarwood I guess so
14:24:59 sean-k-mooney i dont think so . i mean they could but dont have logisn to do so
14:25:05 kashyap Yeah, that's the question. The simplest way to get this going is to have a pre-made template (which I'll make) image that Just Works
14:25:24 sean-k-mooney but ya having nodepool upload it as a glance image to the base cloud was one of the thigns i was thinking of
14:25:40 sean-k-mooney but infra also publish the images too on a webshare
14:27:42 sean-k-mooney here https://nb03.opendev.org/
14:27:57 sean-k-mooney actully no that the lgos there is a place
