| efried | dhellmann bnemec I've been playing around and I can't get deprecated_reason to show up anywhere. Looking at the code, I can't figure out why that would be. | 14:24 |
| efried | Also tried advanced=True, and that message isn't showing up either. | 14:24 |
| *** zhangguoqing has quit IRC | 14:26 | |
| dhellmann | efried : can you share your sample script in a pastebin? | 14:28 |
| dhellmann | efried : I think the advanced stuff is for the sample generator? | 14:28 |
| efried | dhellmann Yeah, I'm clearly not looking at the right source. Stand by. | 14:29 |
| efried | dhellmann https://pastebin.com/7Stpmj3W | 14:30 |
| dhellmann | ok, let me poke it a bit locally | 14:30 |
| efried | dhellmann And here's my conf: | 14:30 |
| efried | https://pastebin.com/PHBp6UAA | 14:30 |
| dhellmann | efried : and how are you running the script? | 14:33 |
| efried | dhellmann python cfgtest.py --config-file tmp/f.conf | 14:33 |
| dhellmann | k | 14:34 |
| efried | I know it's finding the file cause it's printing out '2' | 14:34 |
| efried | took me a while to get to that point ;-) | 14:34 |
| *** zz_dimtruck is now known as dimtruck | 14:34 | |
| dhellmann | efried : ok, I don't see any code trying to print the deprecation reason | 14:36 |
| dhellmann | I do see the sample generator using that value | 14:36 |
| dhellmann | we could enhance oslo.config to print that data, too | 14:36 |
| efried | dhellmann I thought I saw it in generator.py, but it's not the right message format. | 14:36 |
| dhellmann | well, the generator code is only used when you're building a sample config file, it's not used at runtime | 14:36 |
| *** zhangguoqing has joined #openstack-oslo | 14:36 | |
| efried | okay. | 14:37 |
| efried | Where's the source code that prints the message, "Option "test" from group "mygroup" is deprecated for removal. Its value may be silently ignored in the future." ? | 14:37 |
| dhellmann | when I run the program as you describe I do get a log message warning me that test from mygroup is deprecated for removal | 14:37 |
| efried | I tried grepping through all of oslo_config and couldn't find that guy. | 14:37 |
| *** zhangguoqing has quit IRC | 14:37 | |
| dhellmann | that's in oslo_config/cfg.py around line 955 | 14:38 |
| dhellmann | you probably couldn't find it because the message isn't all on one line | 14:38 |
| *** lpetrut_ has quit IRC | 14:38 | |
| dhellmann | you could enhance that message to add the reason text, if there is reason text | 14:38 |
| efried | dhellmann Yup. Was trying various line-split permutations, but hadn't hit that one yet ;-) | 14:38 |
| efried | dhellmann Okay. It's not a huge deal if it doesn't work - just as long as I know it's not my fault ;-) | 14:39 |
| dhellmann | :-) | 14:39 |
| dhellmann | let me see if I can get it to include the reason | 14:39 |
| efried | dhellmann You want me to open a launchpad bug? Propose a fix? (Does that happen in review.openstack.org or via github pull request?) | 14:40 |
| dhellmann | efried : we don't need a bug (the oslo team isn't quite so strict about tracking this sort of thing) | 14:42 |
| dhellmann | a patch would go through review.openstack.org | 14:42 |
| dhellmann | I'm working on that now | 14:42 |
| efried | Neat, thanks. | 14:42 |
| efried | dhellmann I'm also not seeing any result of setting advanced=True | 14:43 |
| efried | Which may or may not be fixed in the same spot. | 14:43 |
| efried | (I don't need that one, but since you're in there...) | 14:43 |
| dhellmann | a lot of these annotation options are really only useful for the sample generator | 14:44 |
| dhellmann | that one means "you probably don't need to set this" | 14:44 |
| efried | Okay. Maybe I missed it, but are they documented as such? | 14:46 |
| dhellmann | probably not | 14:47 |
| dhellmann | it would be useful to annotate the values that are only used that way, though | 14:48 |
| dhellmann | I think when we were adding them, we weren't considering how it might be confusing like this :-/ | 14:48 |
| efried | If we're documenting, something that would have saved me some time is how to actually load a config file. | 14:49 |
| efried | The part about doing CONF(argv[1:]) where argv contains --config-file /path/to/file.conf | 14:49 |
| efried | I wound up figuring that out by looking at the nova-compute source. | 14:50 |

| dhellmann | efried : ^^ | 15:03 |
| dhellmann | efried : you don't have to explicitly give the path unless the file is not in the expected location | 15:03 |
| efried | dhellmann Okay. But the CONF(argv[1:]) thing and the --config-file thing. | 15:04 |
| dhellmann | efried : https://docs.openstack.org/developer/oslo.config/cfg.html#loading-config-files | 15:05 |
| efried | dhellmann Right - that doc was frustrating for me. I don't know what "the config manager has two CLI options" means | 15:06 |
| efried | I.e. what's "the config manager" in that case? | 15:06 |
| efried | oh, now I see the argv thing. | 15:06 |
| dhellmann | the ConfigOpts instance is the "config manager" | 15:06 |
| efried | Okay. I'm probably the dumb one, but I'll just say, as a noob, I was not able to get from point A to point B by reading that (and I did read it). | 15:07 |

| dhellmann | we have a lot of the parts, but I'm not sure they're necessarily in order | 15:13 |
| dhellmann | efried : this may be a case of me knowing things a little too well to see where we're not introducing concepts well enough. I'd be happy to collaborate with you on improving that. | 15:14 |
| dhellmann | i.e., if you can help outline some intro material that would be useful, I can help fill in the details | 15:14 |

| EmilienM | dhellmann: hey, about https://review.openstack.org/#/c/454897/ - do we want to wait for Boston to continue the work/discussions here? | 19:21 |
| EmilienM | I'm curious if we could maybe write a PoC to have something to demo | 19:21 |
| EmilienM | or if we would rather want to wait for Boston and discuss further | 19:22 |
| dhellmann | EmilienM : I don't expect to have time to write a poc before the summit, but could probably by pike-3 | 19:22 |
| dhellmann | but I'd like some feedback about the direction before starting so much refactoring work | 19:22 |
| dhellmann | the replies about not wanting to mix files a config servers, for example, was a bit of a surprise | 19:23 |
| dhellmann | or rather that people *would* want to do that | 19:23 |
| dhellmann | and I would like to work out what to do about the mutable options stuff, since I realized that as it's currently written it will break the ability to change logging settings, since that needs an explicit triggering action to rebuild the logger hierarchy | 19:24 |
| EmilienM | yeah the spec that you wrote was super useful to find eventual blockers and things to adress | 19:24 |
| dhellmann | yeah, and I would like to see if we can work through those before writing too much code | 19:25 |
| dhellmann | the mutability thing in particular is tricky | 19:25 |
| dhellmann | I don't know if lxsli is still around to provide input on that | 19:26 |
| EmilienM | ok, waiting is good | 19:26 |
| dhellmann | I have no idea who, if anyone, uses it | 19:26 |
| EmilienM | dhellmann: I've been trying to find a plan B (if we decide to not use etcd) without using templates | 19:27 |
| dhellmann | we might be able to generate a template using the config generator | 19:27 |
| EmilienM | and I haven't found anything except using config files | 19:27 |
| dhellmann | we'd add a new output mode for "confd template" | 19:27 |
| EmilienM | dhellmann: that's what we do in tripleo | 19:27 |
| EmilienM | we use oslo config generator to generate the config and override the parameters with puppet | 19:27 |
| dhellmann | oh, why isn't that in oslo.config? | 19:28 |
| dhellmann | ah | 19:28 |
| dhellmann | nm, I get it | 19:28 |
| EmilienM | that way, we don't maintain templates and provide full config to operators | 19:28 |
| EmilienM | dhellmann: let me show you the result, a sec | 19:28 |
| EmilienM | dhellmann: example with nova http://logs.openstack.org/03/457603/8/check/gate-tripleo-ci-centos-7-scenario001-multinode-oooq/4696e34/logs/etc/nova/nova.conf.txt.gz | 19:28 |
| EmilienM | it has all options that are possible, so operators know about them | 19:29 |
| dhellmann | how do you override the values? | 19:29 |
| EmilienM | dhellmann: a few years ago (in 2011 I think), we wrote a Puppet provider (ruby), that looks for the parameter in the file and change the string to be param=value | 19:29 |
| dhellmann | aha | 19:29 |
| EmilienM | it works well with sections and multi options | 19:30 |
| dhellmann | so my idea is to have the generator write a file that can be used as input to confd | 19:30 |
| EmilienM | well, it works for all uses cases in OpenStack | 19:30 |
| EmilienM | ah that's a good idea too | 19:30 |
| dhellmann | the problem is sometimes you don't know what sections you need in advance | 19:30 |
| dhellmann | for example, cinder backends | 19:30 |
| EmilienM | as long as we 1) don't maintain template 2) provide a common interface to get parameters (what bnemec is working on) | 19:30 |
| EmilienM | yeah corner cases could be figured later maybe | 19:30 |
| EmilienM | but I like the idea | 19:30 |
| dhellmann | well, we know that's going to be an issue we'd have to solve to make it usable | 19:31 |
| dhellmann | maybe something driving the config generator could feed it extra info somehow, but then we have a whole new way to specify what those things are | 19:31 |
| EmilienM | so we would need to rewrite oslo config generator a bit, no? | 19:31 |
| dhellmann | yeah, we would need changes | 19:32 |
| dhellmann | though it becomes a sort of weird halfway tool at that point, taking *some* runtime parameters (the backend sections to create) and discovering the rest automatically | 19:33 |
| dhellmann | you couldn't just run the tool and then use the output to configure cinder | 19:33 |
| dhellmann | you'd have to have some of the cinder config to pass in | 19:33 |
