| asalkeld | re: taskflow this who design is around not assuming success and not even needing to know it right away | 03:16 |
| asalkeld | so a lot of taskflow is not needed | 03:17 |
| asalkeld | (tracking state) | 03:17 |
| asalkeld | as we do this separately | 03:17 |
| asalkeld | what we do need it dealing with taskrunner health | 03:18 |

| SpamapS | lifeless: really good | 03:27 |
| SpamapS | lifeless: really well rather :) | 03:27 |
| SpamapS | asalkeld: so the general feeling on taskflow is that it doesn't make any of the things we put on the whiteboards simpler. | 03:28 |
| SpamapS | asalkeld: we aren't really sold that it will help with abstracting async job management either. | 03:28 |
| asalkeld | and there seems to be alot of setup code too | 03:28 |
| SpamapS | asalkeld: the setup code is intended to force explicit decisions about things that most code doesen't specify | 03:29 |
| *** julienvey has joined #heat | 03:29 | |
| asalkeld | maybe, but makes using it quite a pain | 03:29 |
| asalkeld | compared to the carrots of the world | 03:30 |
| SpamapS | like when I have non-dependent tasks, do I expect to always run them in serial, or can they be run in parallel? | 03:30 |
| SpamapS | asalkeld: the idea is to go through the pain at coding time, not code-explosion-debugging time. | 03:30 |
| SpamapS | that I like. :) | 03:30 |
| SpamapS | But I feel like our problem space may be too dynamic to be able to be entirely explicit like that. | 03:31 |
| asalkeld | yip | 03:31 |
| SpamapS | the individual resource plugins may be static enough to benefit | 03:32 |
| SpamapS | but we're wanting to do the opposite: NOT rewrite the resource plugins. | 03:32 |
| asalkeld | yes, that we do | 03:32 |
| asalkeld | plugins have a way of been written in the wild | 03:33 |
| asalkeld | shame for them all to break | 03:33 |
| SpamapS | also, arguably the OpenStack plugins that can't just have a single call to their target API that says "create me with these things..." or "delete this one" is a broken API. | 03:33 |
| *** julienvey has quit IRC | 03:33 | |
| *** cmyster has joined #heat | 03:34 | |
| *** cmyster has quit IRC | 03:34 | |
| *** cmyster has joined #heat | 03:34 | |
| SpamapS | but realistically all API's are a little broken. :) | 03:34 |
| asalkeld | really a new resource api does only need one __call__() that takes the properties (including a resource state) | 03:35 |
| *** sdake has joined #heat | 03:36 | |
| SpamapS | anyway, we think there will need to be a split in resource plugins, where the resource plugin author needs to specify the one method to call with the physical resource id that returns details, in 'dict of properties' form about the resource. | 03:39 |
| *** ckmvishnu has joined #heat | 03:40 | |
| SpamapS | also we may have to deprecate returning _anything_ from handle_create, and instead only allow serializables that can be passed through the message bus. | 03:43 |
| SpamapS | otherwise we have to keep observer and converger in the same process/call stack. | 03:43 |
| SpamapS | (since we currently do things like return coroutines) | 03:44 |
| asalkeld | unless the resource has a serialize function | 03:44 |
| asalkeld | that can hook into oslo.message | 03:44 |
| asalkeld | but too many details really at this point | 03:45 |
| *** kebray has quit IRC | 03:45 | |
| *** kebray_ has joined #heat | 03:45 | |
| asalkeld | need to code a bit, to find the problems | 03:45 |
| SpamapS | well we can't really serialize a coroutine.. which users can return and expect to get check_create_complete | 03:46 |
| *** ccrouch has joined #heat | 03:46 | |
| *** piyush has joined #heat | 03:47 | |
| SpamapS | like in nova server, check_update_complete gets a list of scheduler tasks | 03:47 |
| *** sgordon has quit IRC | 03:47 | |
| SpamapS | asalkeld: so we'd probably have to keep working with an in-process observe for anything that didn't have a serialize method or declare itself as safely serializable. | 03:48 |
| asalkeld | SpamapS, we could have a wrapper resource type | 03:48 |
| openstackgerrit | Zhenguo Niu proposed a change to openstack/heat: Remove the unused doc path heat/doc https://review.openstack.org/115487 | 03:48 |
| asalkeld | that deals with the current resources | 03:48 |
| SpamapS | asalkeld: log a warning "resource plugin x.y.z cannot serialize messages. This is deprecated, please write a serialize method or return serializable data types." | 03:48 |
| SpamapS | asalkeld: there's no way to serialize that list of scheduler tasks. It just has to stay in the process that created the objects. | 03:49 |
| *** samstav has quit IRC | 03:49 | |
| asalkeld | sure | 03:49 |
| SpamapS | so we'll need an escape valve.. the one we'll have to use is to stay in process and observe/block while such misbehaving plugins are being observed. And they may never be continuously observable. | 03:50 |
| SpamapS | Not sure if one release is enough time for that plugin API deprecation though. :p | 03:51 |
| SpamapS | we could also just deprecate it but leave it in for BC until the end of time | 03:51 |
| asalkeld | i don't think it's a problem as long as they work | 03:51 |
| SpamapS | since it is sort of a deployer thing that you're making these weird plugins wrong... ;) | 03:52 |
| SpamapS | anyway.. getting sleepy | 03:52 |
| asalkeld | later | 03:52 |
| SpamapS | asalkeld: whiteboards are pretty interesting.. but may be undecipherable to those who weren't in the room. ;) | 03:52 |
| asalkeld | they look ok | 03:52 |
| asalkeld | but conversation would be good too:) | 03:53 |

| ckmvishnu1 | uuid record inserted in stack table as part of _pre_upgrade_xx is not the same when it comes to _check_xx | 09:15 |
| shardy | ckmvishnu1: are you sure it's not data from one of the previous migration tests? | 09:16 |
| shardy | (the DB content is persisted between tests, unlike all other non-migration tests) | 09:17 |
| ckmvishnu1 | i see your tests as well. none of the records retail correct uuids | 09:17 |
| shardy | You mean the backup column migration? | 09:18 |
| ckmvishnu1 | ('s2', '9e9deba9-a303-5f29-84d3-c8165647c47e') inserted in _pre but in check i get "a1535d1d-902c-46ed-8d51-ddd368da9c32" | 09:18 |
| shardy | I tested that locally and I'm pretty sure the UUID's for stack.id were fine | 09:18 |
| ckmvishnu1 | Yesh | 09:18 |

| praveenkumar | shardy: there is no auth_token variable for Client or client object http://paste.fedoraproject.org/126960/85279741/ | 09:46 |
| *** miarmak has joined #heat | 09:47 | |
| shardy | praveenkumar: Oh, I thought you meant when driving via the CLI, in shell.py we get the auth_token and pass it into the client | 09:48 |
| shardy | The Client object doesn't currently do that automatically for you AFAIK | 09:49 |
| praveenkumar | shardy: ah, so how we can use client python lib for doing different operation for heat. | 09:49 |
| miarmak | Hi guys! | 09:50 |
| miarmak | Does heat have smth like 'force delete stack'?.. | 09:50 |

| miarmak | thx, I've already found the answer =) | 10:00 |
| *** miarmak has quit IRC | 10:00 | |
| shardy | praveenkumar: http://paste.fedoraproject.org/126964/52875914/ | 10:01 |
| shardy | probably we need to add a convenience authenticate() method to the client to make that slightly easier | 10:01 |
| *** sorantis has quit IRC | 10:02 | |
| shardy | actually http://paste.fedoraproject.org/126967/08529025 | 10:03 |
| shardy | that was getting two tokens | 10:04 |
| praveenkumar | shardy: right, AFAIK all other client have authentication method once we create client object. | 10:05 |
| *** saju_m has joined #heat | 10:06 | |
| *** saju_m has quit IRC | 10:07 | |
| *** saju_m has joined #heat | 10:07 | |
| shardy | praveenkumar: yeah, we should add that, but note if you're interacting with more than one client it's much better for performance to just request one token and pass it into each one | 10:08 |
| *** openstackgerrit has quit IRC | 10:10 | |
| praveenkumar | shardy: yes agreed but it's handy when we have a auth check before perform any operation using client object (otherwise during this operation it will through exception which we could have handled during auth). | 10:11 |

| *** Qiming has joined #heat | 10:51 | |
| shardy | SpamapS: thanks, how's it all going there? | 10:52 |
| shardy | interested in more details re "blueprint for improving multi-engine "workers"" | 10:53 |
| shardy | sounds somewhat related to the engine decoupling work I'm doing atm | 10:53 |
| SpamapS | shardy: it is! | 10:56 |
| SpamapS | shardy: but it is more about making process management stronger, so that we can take advantage of multiple cores automatically without fear, rather than defaulting --num-workers to 1. | 10:57 |
| *** nosnos has quit IRC | 10:57 | |
| SpamapS | shardy: so the decoupling work you're doing would be served by it. | 10:58 |
| *** kopparam has quit IRC | 10:58 | |
| shardy | SpamapS: is that a heat issue though, or a devstack/tripleo/distributor one? | 10:58 |
| shardy | I agree that it would be beneficial to get typical installations using more than one worker or process though :) | 10:58 |
| *** nkhare has quit IRC | 11:01 | |
| SpamapS | shardy: it is an oslo issue | 11:02 |
| SpamapS | shardy: POSIX has had fork() and signal() for decades.. why we want to punt concurrency to the OS I've no idea. | 11:03 |
| SpamapS | shardy: at issue is that we're more involved than say, nova-api or neutron-server, which are stateless. | 11:04 |
| *** piyush has joined #heat | 11:05 | |
| SpamapS | so what we need to do is make oslo's service.ProcessLauncher more robust and have a re-exec mode. And we also need to talk about what is a sane reasonable default, since there is resistance to "use all the CPUs" | 11:06 |
| shardy | SpamapS: I guess I'll let you argue that out with zaneb, I've not got a particularly strong opinion on how we do it, other than wanting to use engine scale-out as a stepping stone to a fully distributed model | 11:07 |
| *** sgordon has joined #heat | 11:08 | |
| SpamapS | I'm thinking a good default may be if ncpus <= 2: ncpus else: round_up(ncpus/2) | 11:09 |
| SpamapS | shardy: basically I'm not convinced that "systemd and/or upstart do it better" given that neither of them have any knowledge of how python or heat-engine works. | 11:10 |
| SpamapS | shardy: we had a brief discussion.. and I agreed we probably need a wider debate. :) | 11:10 |
| shardy | Well they don't need to, they just need to start several processes | 11:10 |
| shardy | but your solution wfm, the question is does that calculation belong inside heat, or e.g in devstack (and other things which install and configure heat) | 11:11 |
| SpamapS | in heat, as we have quite a bit more insight into how much our processes cost | 11:12 |
| SpamapS | (also consider that neutron-server and nova-api already do a fork per CPU) | 11:13 |
| *** tengqim has joined #heat | 11:13 | |
| pas-ha | shardy, as you are the keystone expert in the team :) - can I ask for a Keystone catalogue without any credentials (during heat-engine startup)? | 11:13 |
| shardy | yeah, tbh I've personally got no issue with just doing that, provided it's trivially overridable in the config file | 11:13 |
| *** kopparam has joined #heat | 11:13 | |
| shardy | pas-ha: no | 11:14 |
| SpamapS | Also I'm quite confused why we wouldn't want a heat-engine per CPU.. when we're talking about at worst 100MB per CPU.. and any box that has 8CPUs and doesn't have an extra 800MB of RAM to give to concurrency is not a box I've seen. ;) | 11:14 |
| shardy | you need credentials, which could be the heat service user | 11:14 |
| SpamapS | But anyway, this also leads into convergence where the workers _SHOULD_ become lighter weight and thus less scary to run many | 11:15 |
| * SpamapS notices uber is almost here... o/ | 11:15 | |
| shardy | SpamapS: yeah, don't know if you saw my comment on the convergence-engine spec, but I've been thinking heat-engine should get scaled out and become the convergence engine | 11:16 |
| pas-ha | ok, thanks, will investigate further | 11:16 |
| shardy | Then we just gradually decouple all-the-things in the engine until we reach the resource-granularity vision you propose in the spec | 11:17 |
| tengqim | um iphone is too small for IRC | 11:17 |
| * shardy -> lunch | 11:18 | |

| SpamapS | shardy: +1 I think given what we worked through yesterday that makes perfect sense. | 12:39 |
| *** julienve_ has quit IRC | 12:40 | |
| SpamapS | shardy: there was some desire before to split them early to force rethinking of async jobs and perhaps even disallow the new processes from doing full stack loads but that is put to rest. It's just async casts to RPC apis. | 12:41 |
| shardy | SpamapS: Cool, sounds like that aligns well with what I've been thinking then :) | 12:42 |

| pas-ha | answer - recheck all failures | 14:23 |
| pas-ha | the new fresh oslo.db just got released. the problem AFAIU is that different oslo.db is used for unittests and for gate devstacks (one is from pypi, another form master) | 14:24 |
| *** rwsu has quit IRC | 14:24 | |
| pas-ha | or vise versa | 14:24 |
| *** kopparam has quit IRC | 14:24 | |

| shardy | mspreitz: You can add me if you wish, also tspatzier is often active reviewing in heat-templates, although I think he's not around this week | 16:54 |
| mspreitz | shardy: thanks. In this case, I guess my question is how do I prompt those two guys to revisit the change, I have submitted revised patch sets since they last reviewed. | 16:56 |
| shardy | mspreitz: are we talking about https://review.openstack.org/#/c/97366/? | 16:56 |
| mspreitz | yes | 16:56 |
| shardy | FWIW I would've +2'd it had my CFN/HOT comment been addresed ;) | 16:56 |
| shardy | I get the point of having a good example of the AWS resources (we already have some), just not in HOT syntax | 16:57 |
| shardy | maybe I'm being too much of a purist, hence waiting for others to comment | 16:58 |
| mspreitz | I felt it is defensible since the AWS resources, in some cases, have unique virtues | 16:58 |
| shardy | I'm sorry you haven't had feedback yet, they are valuable new examples :) | 16:58 |
| *** alexheneveld has quit IRC | 16:58 | |
| mspreitz | I do not think we should have to forbid using the new syntax to get those unique virtues | 16:58 |
| shardy | Ok, I just would, in general, prefer our hot example templates to guide folks to the native resources where possible | 16:59 |
| mspreitz | Sure, and that's what most of that change does. | 16:59 |
| mspreitz | Maybe what we need most here is other reviewers | 16:59 |
| shardy | If you're very keen to keep that example for the sake of comparison, I can compromise ;) | 17:00 |
| mspreitz | Any suggestions for reviewers to add? | 17:00 |
| mspreitz | Yes, I do think comparison is valuable | 17:00 |
| mspreitz | However, I will also admit that comparison of function, my main interest, can be done even if the syntax is different | 17:01 |
| shardy | I guess your approach makes them more directly comparable, I'm just scared of folks cut/pasting hybrid abominations and getting confused | 17:02 |
| mspreitz | I understand that | 17:02 |
| mspreitz | Look, the syntax choice is not a big deal to me | 17:02 |
| mspreitz | If it will get you over the hump, I will change it. | 17:03 |

| openstackgerrit | Randall Burt proposed a change to openstack/heat: Allow for setting ViP ID https://review.openstack.org/115710 | 17:03 |
| *** bvivek has joined #heat | 17:03 | |
| therve | mspreitz, FWIW I didn't approve it because I still disagree with the examples | 17:04 |
| mspreitz | therve: in what way do you disagree? | 17:04 |
| therve | mspreitz, On using metering value all around for nothing | 17:04 |
| mspreitz | It's not for nothing. It is illustrating the plumbing through Ceilometer, the building blocks for autoscaling | 17:05 |
| mspreitz | The comments in the latest revisions explain | 17:05 |
| mspreitz | they show how you can do Ceilometer queries that fetch that data | 17:05 |
| therve | The plumbing through Ceilometer is done creating Ceilometer resources | 17:05 |
| mspreitz | The Ceilometer samples are created regardless of what is written in the template; what my templates add is metadata that allow specific Samples to be selected for use in alarms | 17:06 |
| mspreitz | or for use in other ways | 17:07 |
| *** jasond has quit IRC | 17:07 | |
| therve | But you need to create alarms separately | 17:07 |
| therve | Anyway | 17:07 |
| therve | Also you should remove the image default so that validation passes | 17:07 |
| therve | I should make that job voting... | 17:08 |
| *** bvivek has quit IRC | 17:08 | |
| mspreitz | therve: pls explain about the image default, I did not know there is an issue there | 17:08 |
| *** jay_t_c has joined #heat | 17:08 | |
| jay_t_c | hello, I have a question regarding an property of OS::Heat::AutoScalingGroup resource | 17:10 |
| jay_t_c | a property | 17:10 |
| *** wpf has quit IRC | 17:10 | |
| mspreitz | therve: can you please explain what is the issue with an image default? jay_t_c: go ahead and ask | 17:11 |
| *** alexpilotti has quit IRC | 17:12 | |
| jay_t_c | trying to specify LoadBalancerNames as a property | 17:12 |
| *** wpf has joined #heat | 17:12 | |
| mspreitz | jay_t_c: there is no such property | 17:12 |
| mspreitz | OS::Heat::AutoScalingGroup knows nothing about load balancers | 17:13 |
| jay_t_c | is that only available in AWS::AutoScaling::AutoScalingGroup | 17:13 |
| mspreitz | Deliberately so. | 17:13 |
| openstackgerrit | Randall Burt proposed a change to openstack/heat: Allow for setting ViP ID https://review.openstack.org/115710 | 17:13 |
| mspreitz | jay_t_c: right... | 17:13 |
| mspreitz | Since the member type of an OS::Heat::AutoScalingGroup can be anything, there is no attempt to make that kind of group know how to connect any kind of member to a LB | 17:13 |
| mspreitz | Instead the idea is that you make the member type be a stack that makes the connection, using an OS::Neutron::PoolMember | 17:14 |
| mspreitz | I have another batch of examples that do this, not yet submitted here | 17:14 |
| jay_t_c | a nested stack | 17:14 |
| SpamapS | We talked a lot about how to link groups to other resources | 17:15 |
| SpamapS | I am hoping to spec up a way to do that w/ stevebaker's help | 17:15 |
| mspreitz | jay_t_c: yes, a nested stack. Doubly nested, in fact, since a scaling group is implemented by a nested stack | 17:15 |
| *** Qiming has quit IRC | 17:15 | |
| jay_t_c | basically what i am trying to do is automatically add an autoscaled instance to a member list | 17:15 |
| mspreitz | Zane got a change approved today that gives another way to skin that cat | 17:16 |
| SpamapS | Ansible has this really nice thing where you can make a single play in a playbook happen in a loop with a list from another play or variable... I think we can borrow that. | 17:16 |
| SpamapS | so you say do this once, replace {{ item }} with every item from this list and create 1 per item. | 17:16 |
| mspreitz | Today's change is adding output and output_list attributes to a scaling group | 17:16 |
| mspreitz | So you can get out the things you need to connect to your LB or whatever | 17:16 |
| jay_t_c | mspreitz: you said you have examples of doing this | 17:18 |
| *** swygue has joined #heat | 17:18 | |
| mspreitz | yes | 17:18 |
| mspreitz | I have examples of the nested stack approach | 17:19 |
| mspreitz | I agree with SpamapS that, as of today, that is not the only way to skin this cat | 17:19 |
| *** harlowja_away is now known as harlowja | 17:19 | |
| jay_t_c | mspreitz: anywhere that i could find the example to look at for reference? | 17:21 |
| SpamapS | mspreitz: you're doing a nested stack per group member somehow? | 17:21 |
| mspreitz | jay_t_c: I will paste in an etherpad for now... just a minute... | 17:21 |
| jay_t_c | thanks | 17:21 |
| mspreitz | jay_t_c: top level template is in https://etherpad.openstack.org/p/lpm5uEXcMy | 17:23 |
| mspreitz | nested template is in https://etherpad.openstack.org/p/Syno4WlzjZ | 17:23 |
| mspreitz | SpamapS: yes, OS::Heat::AutoScalingGroup allows that. One way is simply to use the template name as the member resource type | 17:24 |
| *** ev0ldave has joined #heat | 17:28 | |
| mspreitz | therve: I see that there is checking of the default. I can switch to cirros-0.3.2-x86_64-uec, that's in the standard list, right? | 17:28 |
| mspreitz | SpamapS: the CLI will follow the reference up and package the contents; Horizon does not do this. | 17:29 |
| mspreitz | therve: I claim an example template that tags Samples and explains how to query for such tagged Samples, but does not create alarms, is still valuable because it is teaching some stuff that people need to know about the mechanism | 17:32 |
| jay_t_c | mspreitz: so you are just specify paramaters for the nested stack in the resource section of the top level stack? | 17:32 |
| mspreitz | jay_t_c: I am not sure what you mean. There is no magic here, you will see explicit propagation from top-level parameter to resource property | 17:33 |
| mspreitz | therve: I also claim that there is virtue in having examples that depend on no non-standard stuff. Ceilometer is not installed by DevStack by default. | 17:33 |

| zaneb | mspreitz: *Heat* is not installed by devstack by default ;) | 17:50 |
| mspreitz | zaneb: OK, but moot in this case | 17:51 |
| zaneb | I think it's OK to rely on core stuff in OpenStack | 17:52 |
| zaneb | the current de-integration discussion on openstack-dev notwithstanding :D | 17:52 |
| *** ramishra has quit IRC | 17:53 | |
| zaneb | mspreitz: hey, email question for you. "Do you know if there is a plan to integrate the server group into heat in the same way it is done for security group ?" | 17:55 |
| zaneb | mspreitz: I think there was a plan along those lines, right? | 17:55 |
| viktors | zaneb: Hi! Can you please look at patch https://review.openstack.org/#/c/115674/ ? It should fix gate tests in Heat. | 17:55 |
| mspreitz | zaneb: did I overlook some email? | 17:55 |
| zaneb | mspreitz: no it was a private email :( | 17:56 |
| mspreitz | zaneb: not sure I know the reference. How is "it" done for security group? | 17:56 |
| zaneb | tempted to just redirect them to the list | 17:56 |
| zaneb | I think they mean a specific property for server groups, as opposed to going through the scheduler hints | 17:56 |

| therve | mspreitz, But use ceilometer, or don't. The templates are in a weird middle ground. | 18:26 |
| therve | mspreitz, Regarding the images default, there probably shouldn't be any. It's hard to have a value available in all environments | 18:27 |

| *** jasond has joined #heat | 18:28 | |
| *** viktors has quit IRC | 18:28 | |
| mspreitz | therve: the templates do not use Ceilometer, they only do some tagging that happens to be valuable if you have Ceilometer. I could split each template into two, one that does no tagging and another that tags and creates an alarm. I was not looking forward to doubling the number of templates. | 18:28 |
| mspreitz | therve: about the image default, I will simply remove it | 18:29 |
| therve | mspreitz, My point is that if you have Ceilometer, you use it in the template | 18:29 |
| therve | You don't expose some weird query in the output | 18:29 |
| mspreitz | therve: my main goal was to create some simple templates that exercise basic stuff with minimal dependencies. The query is not weird, it shows what's going on. | 18:30 |
| therve | mspreitz, Agree to disagree | 18:31 |
| mspreitz | therve: OK, thanks | 18:31 |
| *** mohits_ has joined #heat | 18:32 | |
| *** mohits has quit IRC | 18:35 | |
| shardy | mspreitz: Couldn't you just add a Ceilometer alarm resource, and have it hit the ScalingPolicy URL? | 18:36 |
| shardy | Then they'd be fully-functional autoscaling examples, rather than partial examples, which I think is therve's point | 18:36 |
| mspreitz | shardy: sure, but that adds a dependency on Ceilometer | 18:36 |
| mspreitz | I understand that therve does not like the partiality | 18:37 |
| mspreitz | but I like the lack of dependencies | 18:37 |
| mspreitz | There is already a more complete example from therve | 18:37 |
| mspreitz | if someone wants to see that | 18:37 |
| mspreitz | It needs one fix now, but that's another matter. | 18:37 |
| mspreitz | I think what I will do is erase the tagging from these templates, and possibly make one more that does the tagging, exhibits the query term, and makes an alarm | 18:38 |
| shardy | mspreitz: having a "ceilometer_query" when you expect it to work without ceilometer is somewhat confusing | 18:38 |
| mspreitz | Or maybe just skip that, since there is already an example that creates an alarm | 18:38 |
| shardy | mspreitz: +1, sounds like a good plan | 18:39 |
| shardy | I do like having the outputs and descriptions in there, as it's good for showing folks how it works | 18:39 |
| mspreitz | I am considering expanding the existing examle that makes an alarm, adding the query term and explanation. | 18:39 |
