| inc0 | good morning | 07:38 |
| inc0 | asalkeld, ping | 07:38 |
| asalkeld | hi inc0 | 07:39 |
| asalkeld | i did look at your code | 07:39 |
| inc0 | yesterday I've pushed props updates | 07:39 |
| *** vijayagurug has joined #heat | 07:39 | |
| inc0 | but general idea should be visible before | 07:39 |
| *** vijayagurug has left #heat | 07:39 | |
| inc0 | what do you think about that approach? | 07:39 |
| asalkeld | so it's seems very heavy in the recalulation phase | 07:41 |
| asalkeld | we do need to be to careful about hitting api's a lot | 07:42 |
| asalkeld | (of other services) | 07:42 |
| inc0 | well, I was rather thinking of different approach | 07:42 |
| *** alexheneveld has joined #heat | 07:42 | |
| inc0 | there will be DB table which will represent "reality" | 07:42 |
| inc0 | probably current resource table | 07:42 |
| asalkeld | help me here: what keeps calling "converge" | 07:43 |
| *** achanda has joined #heat | 07:43 | |
| inc0 | coverage will be infinite loop | 07:43 |
| inc0 | nothing will actually call it | 07:43 |
| asalkeld | https://github.com/inc0/heat-convergence-prototype/blob/iterative/converge/engine.py#L29 | 07:44 |
| inc0 | its main reason is to keep looking at reality_database_table and stack_goal_table and try to keep these 2 aligned | 07:44 |
| inc0 | this is hack to allow tests to specify "now simulate x iterations of coverage" | 07:44 |
| asalkeld | i like some aspects of this, the setting of the goal vs. reality | 07:44 |
| inc0 | main idea is that coverage won't have notion of graph whatsoever | 07:45 |
| inc0 | all it does is check "what actions can be performed *right now*" | 07:45 |
| inc0 | and schedules performing these | 07:45 |
| *** saju_m has quit IRC | 07:46 | |
| inc0 | that don't guarantee what stack will ever finish, but it should finish in finite time | 07:46 |
| inc0 | whats really nice about that - its completely stateless | 07:46 |
| *** achanda has quit IRC | 07:46 | |
| asalkeld | we don't guarentee timelyness | 07:46 |
| inc0 | all it has is "what I have right now" and based on that "what I can do to bring reality a little bit closer to goal" | 07:47 |
| asalkeld | some questions would be: | 07:47 |
| inc0 | that will also mean that stack isn't monolythic thing which eighter fails completely or succeed completely... | 07:48 |
| asalkeld | how expensive is it to re-calulate this every loop | 07:48 |
| inc0 | if we have resources cached in local db? | 07:48 |
| asalkeld | in terms of mem/cpu on large stacks | 07:48 |
| inc0 | I don't think that would even matter | 07:48 |
| *** achanda has joined #heat | 07:48 | |
| asalkeld | inc0, even if you are not calling out to services | 07:48 |
| asalkeld | well tripelo and others have very large templates | 07:49 |
| *** jamielennox is now known as jamielennox|away | 07:49 | |
| asalkeld | so we need to look at this aspect of scale as well | 07:49 |
| inc0 | well, with good db queries and scallability, I still think that will be managable | 07:49 |
| asalkeld | inc0, - not critising you - but this is a good thing to benchmark and understand | 07:49 |
| *** alexheneveld has quit IRC | 07:50 | |
| *** vijayagurug has joined #heat | 07:50 | |
| asalkeld | so we can compare one with the other | 07:50 |
| inc0 | asalkeld, I totally agree, but I think we'll need to do that anyway at some point | 07:50 |
| inc0 | having notion of graph and so on will always be faster than recalculating it | 07:50 |
| inc0 | but what recalculation gives us is statelessness | 07:51 |
| asalkeld | that's fine there are pros/cons | 07:51 |
| inc0 | and, well, I don't think we can apply classical graph approach here | 07:51 |
| inc0 | because graph may change during traversal | 07:51 |
| asalkeld | just good to know what you are giving up to get another benefit | 07:51 |
| inc0 | update, resource can fail after spawn and so on | 07:51 |
| inc0 | I don't ever think that resource is "complete so I don't have to check that again" | 07:52 |
| asalkeld | agree | 07:52 |
| inc0 | if for example we set up VM (one of 1000) | 07:52 |
| inc0 | and it finishes | 07:52 |
| inc0 | so I keep going with graph | 07:52 |
| inc0 | and it fails | 07:52 |
| inc0 | my approach will try to recreate/heal/whatever | 07:53 |
| *** achanda has quit IRC | 07:53 | |
| asalkeld | yip | 07:53 |
| asalkeld | i'd suggest adding some instrumentation to measure mem when you have a template of N resources | 07:53 |
| inc0 | I'd be caucious about measuring a PoC | 07:53 |
| asalkeld | and we can get this on all the algos | 07:53 |
| asalkeld | inc0, maybe - it's just an idea tho' | 07:53 |
| inc0 | because that can be accelerated by having actual db and have better queries and so on | 07:53 |
| inc0 | well, we can time out how long it takes to finishes all test cases;) | 07:54 |
| inc0 | that would give us some idea | 07:54 |
| inc0 | although I think statelessness and therefore scallability is more important than singular performance | 07:55 |
| asalkeld | i am not stressed about performance *that* much, but I am worried about having a linear relationship of memory to template size | 07:56 |
| inc0 | I don't think we need | 07:56 |
| inc0 | when we traverse graph, we don't need to load it into memory really | 07:56 |
| asalkeld | inc0, i am simply trying to get you to think about potential down sides of this approach and face/think about them | 07:56 |
| inc0 | we iterate over every resource in this stack | 07:56 |
| inc0 | and check "am I good?" | 07:56 |
| *** jprovazn has joined #heat | 07:57 | |
| inc0 | so memory wise it will be just space required for single resource | 07:57 |
| inc0 | and status of its immediate neighbors | 07:57 |
| asalkeld | well we could do a query as you suggested we could query for state != complete? | 07:57 |
| inc0 | yup | 07:57 |
| asalkeld | or not converged | 07:58 |
| *** achanda has joined #heat | 07:58 | |
| inc0 | we'll have list of resources_goal, then for each resource goal check if reality matches | 07:58 |
| ekarlso- | is there any of the convergence stuff gone into master atm ? | 07:58 |
| asalkeld | ekarlso-, not yet | 07:59 |
| inc0 | we're testing few approaches | 07:59 |
| asalkeld | yip ^ | 07:59 |
| asalkeld | inc0, any reason you didn't have the action call converge() after it is done? | 08:00 |
| inc0 | cpu-wise it will be heavier, but we can for example add "last checked" flag and check every resource every few minutes | 08:00 |
| inc0 | that would spread the load | 08:00 |
| inc0 | asalkeld, after what is done? | 08:00 |
| asalkeld | inc0, cpu can scale easier than mem | 08:00 |
| inc0 | true, thats why I'm not *that* concerned' | 08:00 |
| *** jcoufal has joined #heat | 08:00 | |
| asalkeld | action == update, when the update is done, call converge (async) | 08:01 |
| inc0 | update call just sets up a goal | 08:01 |
| inc0 | and yeah, we can call converge afterwards | 08:01 |
| inc0 | but that would be one iteration anyway | 08:01 |
| inc0 | so might speed things a little bit, but just a little bit | 08:02 |
| inc0 | creation of a stack isn't atomic action here, it requires n iterations of converge...and we never really know what n is | 08:02 |
| asalkeld | ok | 08:03 |
| inc0 | it will try its best to finish someday | 08:03 |
| inc0 | ;) | 08:03 |
| asalkeld | inc0, i do like it's simplicity | 08:03 |
| inc0 | but that may mean recreating failed resources and so on, so we can't really predict that | 08:03 |
| inc0 | yeah, I don't think you were when Glyph described it | 08:04 |
| inc0 | at meetup | 08:04 |
| inc0 | but I liked this approach very much. I think its very elegant | 08:04 |
| asalkeld | yeah, that was some side chat | 08:04 |
| inc0 | they did that in rackspace, very similar problems | 08:05 |
| pas-ha | morning all | 08:05 |
| inc0 | and they had same problems we're facing (and probably few what we will/would face;)) | 08:05 |
| inc0 | hello pas-ha | 08:05 |

| pas-ha | morning smile break :) | 08:06 |
| inc0 | whats funny, we'll just need to rewrite nova::instance behaviour, and we won't have statefull creation problem anymore:) | 08:06 |
| asalkeld | o, that sucks | 08:06 |
| asalkeld | (nz not on the map) | 08:07 |
| inc0 | I've seen maps where Poland wasn't there (not politically...there was actual see here) | 08:08 |
| inc0 | and we're in very center of Europe | 08:08 |
| asalkeld | must have been a black hole:-( | 08:08 |

| cmyster | having a bit of a problem, I am get_attr-ing a couple of attributes one of them is a subnet id from a nested template that created it. I am trying to pass it to another nested template that creates a load balancer (so it needs the subnet) but it keeps telling me that load balancer cannot be created because it needs a subnet. I have defined the outputs in the network template like so: http://paste.openstack.org/show/138030/ | 09:21 |

| pas-ha | cmyster, not sure, but the attr is "subnets" - might that be that you are getting a list instead of a single subnet? | 09:26 |
| cmyster | pas-ha: I thought about it but only one is being created | 09:27 |
| cmyster | also this is a total ripoff from one of the predefined templates in github... | 09:27 |

| pfreund | is it a different concept in heat ? | 10:54 |
| *** blues-man has quit IRC | 10:55 | |
| therve | pfreund, It's just a property of the Instance resource? | 10:57 |
| therve | You can use that resource in HOT | 10:57 |
| therve | Or use the Server resource and delete_on_termination | 10:57 |
| pfreund | therve: yes sorry I didn't say that I was looking for this parameter in a cinder volume. Is it only on nova servers ? | 10:58 |
| pfreund | oh I get it | 10:59 |

| asalkeld | jpeeler, just got raised in the project 1-1 as it is in an unknown state | 11:20 |
| inc0 | asalkeld, https://review.openstack.org/#/c/134848/4/specs/kilo/external_resource.rst quick question, when res has property A: foo and we use this method to adapt it with property A: bar...should we make immediate update of existing res? | 11:23 |
| *** sorantis has joined #heat | 11:24 | |
| asalkeld | inc0, so when you say property, do you mean the properties that the user can set on the resource or properties of the external_resource? | 11:25 |
| inc0 | I assume there is something that means both...like metadata in nova instance | 11:25 |
| inc0 | something you can set up in tpl and differs from real state | 11:26 |
| asalkeld | inc0, are you just figuring out how this effects "need_to_update"? | 11:27 |
| inc0 | I'm curious what type of behaviour we should take in this case | 11:28 |
| asalkeld | so if the external ref changes we just write it to the db | 11:28 |
| inc0 | I mean, we want to adapt new resource, and it differs from what we have | 11:28 |
| inc0 | in our template | 11:28 |
| asalkeld | yeah, we just change it | 11:28 |
| asalkeld | brutal :) | 11:29 |
| inc0 | on resource right? | 11:29 |
| asalkeld | resource_{data,id} | 11:29 |
| inc0 | then calling external_resource may need immediate update on resource in question....ok I agree, just wanted to clarify in this spec;) | 11:30 |
| *** kopparam has quit IRC | 11:31 | |
| *** jstrachan has joined #heat | 11:32 | |

| asalkeld | inc0, a couple of reasons | 12:03 |
| asalkeld | 1. we don't want to end up with it adopted | 12:03 |
| asalkeld | ( meaning we won't manage the resource until you remove the external_ref) | 12:04 |
| asalkeld | 2. you can keep a resource extenal and just have the convience of a resource to use get_resource and get_attr - but not modify it | 12:05 |
| asalkeld | adopt assumes: you are bringing the resource under control of heat - we are not really wanting that | 12:06 |
| * asalkeld needs to sleep | 12:06 | |
| inc0 | asalkeld, I've put comment to this review...why not introduce "read-only"? | 12:06 |
| asalkeld | early morning heat meeting | 12:06 |
| asalkeld | read-only to what? | 12:06 |
| asalkeld | external == read only | 12:07 |
| inc0 | we mark resource as "read-only" | 12:07 |
| asalkeld | also there is a spec that describes some of this | 12:07 |
| inc0 | add generic flag to every resource | 12:07 |
| asalkeld | shrug, cos' i haven't needed it | 12:07 |
| inc0 | but then we end up with adopt with read-only rather than external_import | 12:08 |
| inc0 | so one logic | 12:08 |
| *** hdd has joined #heat | 12:08 | |
| *** pas-ha has joined #heat | 12:08 | |
| asalkeld | inc0, but people don't want to use the adopt api | 12:08 |

| inc0 | I'd rather teach people to use existing mechanism rather than add new one | 12:11 |
| cmyster | its a philosophical debate ;) | 12:11 |
| cmyster | inc0: is there a chance I can use your pair of eyes? | 12:12 |

| *** GonZo2K has quit IRC | 12:57 | |

| inc0 | shardy, I'm wondering about one thing...in update-replace do we always keep old resource and remove it afterwards? | 12:58 |
| inc0 | and if we consider for example volume attachment | 12:58 |
| *** che-arne has quit IRC | 12:59 | |
| inc0 | can we do update-replace on it? | 12:59 |
| inc0 | there can't be 2 volume attachment for one volume | 12:59 |
| shardy | inc0: Yes, but AFAIK VolumeAttachment allows non-replacement updates of all properties | 13:03 |

| *** ishant has quit IRC | 13:10 | |
| pas-ha | everything is update_allowed=True | 13:11 |

| inc0 | zaneb, I don't see any case which my tests hasn't covered...and it works for me;) | 14:31 |
| zaneb | inc0: well, I checked out your branch directly. and the first thing I get is "AttributeError: 'Resource' object has no attribute '__dict__'" on every single test | 14:32 |
| inc0 | thats strange... | 14:33 |
| inc0 | which python? I'm working on 2.7.8 | 14:33 |
| zaneb | and after fixing that, I get ".....F.F", so two failures | 14:33 |
| zaneb | 2.7.5 | 14:33 |
| inc0 | I get 3 failures on your code;) | 14:33 |
| inc0 | I mean adapted | 14:34 |
| inc0 | but it seems I've covered same cases | 14:34 |
| inc0 | and it works | 14:34 |
| zaneb | yes, I get failures on the adapted branch too | 14:34 |
| zaneb | and even more if I import tests directly from my branch | 14:35 |
| zaneb | https://github.com/zaneb/heat-convergence-prototype/commit/d67d4bf6e2093db177e3317edee8b5d677209384 is the fix for the __dict__ thing btw | 14:35 |
| inc0 | thats funny | 14:36 |
| inc0 | could you please try my repo and my branch directly now? | 14:36 |
| inc0 | (it should fail on one test case, but I'm still implementing it = update_replace3) | 14:37 |
| zaneb | all errors | 14:37 |
| inc0 | oO | 14:38 |
| zaneb | you are using an implementation detail to get the value as a dict. you should use the API instead | 14:38 |
| inc0 | yeah, I wonder what's wrong | 14:39 |
| inc0 | it works for me anyway.. | 14:39 |
| zaneb | well that's how implementation details work - they work for you and then someone else tries it and they don't | 14:40 |
| *** alexheneveld has joined #heat | 14:41 | |
| inc0 | well, with _asdict it works too so I'll just commit this thing | 14:41 |
| inc0 | and done, try now | 14:42 |
| zaneb | ........F. | 14:43 |
| *** mkoderer has joined #heat | 14:43 | |
| zaneb | so just the expected update_replace3 failing | 14:44 |
| zaneb | this thing is brutal on the DB | 14:44 |
| inc0 | algorithm you mean? | 14:45 |
| inc0 | well, its worse than graph approach, thats for sure | 14:45 |
| inc0 | but also stateless | 14:45 |
| inc0 | and I don't think its nearly as brutal as other things...and hey, I'm from intel, if your server can't handle this computation, come and buy new processor;) | 14:46 |
| inc0 | but really, I don't think it will be that critical if we build queries optimally | 14:47 |
| inc0 | most of this will be much better when we'll actually care to make it optimally (I didn't sorry) | 14:48 |
| zaneb | I mean, it's n^2 or worse... when we had n^2 queries in Heat tripleo topped out at ~20 resources per stack | 14:49 |
| *** kitch_ has joined #heat | 14:49 | |
| inc0 | I don't think real thing will exceed n logn | 14:49 |
| inc0 | converge provess will only check n nodes | 14:50 |
| zaneb | tbh after playing around with this branch I'm ready to put it in the 'interesting experiment but dead end' category | 14:50 |
| *** crose has quit IRC | 14:50 | |
| inc0 | and if there is action required it will check node n and immediate neighbors | 14:50 |
| inc0 | so less than n log n | 14:50 |

| *** jcoufal has quit IRC | 14:53 | |
| *** jcoufal_ has quit IRC | 14:54 | |
| zaneb | because it doesn't solve any problems that my branch doesn't, and there is heaps of stuff that is unproven (like exactly how these processes will communicate, whether it can be optimised, &c.) that is all done in my branch | 14:54 |
| *** jcoufal has joined #heat | 14:54 | |
| zaneb | and maybe that can be fixed given enough time | 14:54 |
| sdake | zaneb translator = NIH :) | 14:54 |
| zaneb | but I'm not seeing a major upside, and we need to get moving | 14:55 |
| inc0 | well, upside is that it is actually contionous observer | 14:55 |
| inc0 | so on a longer run, it will be better than multiple separate approaches | 14:56 |
| inc0 | because its one algorithm to rule them all | 14:56 |
| zaneb | also add 'works with the existing resource plugin model' to the list of unproven things | 14:57 |
| inc0 | well, its a major change in architecture, I agree | 14:57 |
| inc0 | I don't see why it wouldn't work with current resource model, but it is unproven | 14:58 |
| zaneb | yeah, what I'm trying to do is basically port our existing code to a distributed model with the minimal possible changes | 14:58 |
| zaneb | agreed, like I said, that can probably all be fixed given enough time, but right now it is not proven by this simulation | 14:59 |
| inc0 | I'm just saying, that we will have to solve this issues eventually | 15:00 |
| inc0 | anyway, when we'll try to make it all really stateless | 15:00 |
| inc0 | it will be much easyier of we consider core algorithm to be stateless from the beginning | 15:01 |
| *** bdossant has quit IRC | 15:01 | |
| zaneb | I'm not actually convinced we want to bake continuous convergence into the architecture. Every user is different; how do we know what the right way to converge is? I would prefer we leave ourselves the option of having the user trigger the convergence through the API (probably via a Mistral timed workflow) | 15:01 |
| zaneb | if we were starting from the beginning that might be true, but we're not - we're starting from Heat as it is now | 15:02 |
| *** bdossant has joined #heat | 15:03 | |
| zaneb | and we have to shoehorn this change in behind the current API, with the current plugins, in a way that enables phase 2 to happen, without changing anything for the user. And we need to do it in Kilo. | 15:04 |
| *** dulek_ has quit IRC | 15:05 | |
| inc0 | but, when we'll want phase2, won't we have to face exactly these problems? | 15:05 |
| inc0 | when one resource dies in the middle of stack-create, we'll have to deal with that | 15:05 |
| inc0 | right now we don't care (given it was complete at some point, afterwards we don't care), in phase 1 we may still not care, but shouldn't we care at some point? | 15:07 |
| zaneb | does https://wiki.openstack.org/wiki/Heat/ConvergenceDesign#Flowchart not cover that just as well? | 15:07 |
| inc0 | yeah, and this would be observer | 15:08 |
| inc0 | only difference would be that observer would be only process there (and worker) | 15:09 |
| inc0 | and we do create in observer | 15:09 |
| inc0 | same as update | 15:09 |
| inc0 | and so on | 15:09 |
| inc0 | one mechanism to take care of | 15:09 |
| zaneb | being able to add the observer in once we have phase 1 is not something that worries me a great deal | 15:11 |
| zaneb | maybe it should :D | 15:12 |
| inc0 | maybe it will:P | 15:12 |
| inc0 | well, you're right, its all unproven and it might cause us problems, but it might give us powerful tools later as well | 15:14 |
| inc0 | its a leap of faith;) | 15:15 |

| inc0 | anyway, lets discuss that tomorrow please, I'm not emotionally bound to my approach (well, maybe a little), I just want to have autohealing in heat one day | 15:24 |
| zaneb | inc0: btw none of your update_replace examples are actually doing an UpdateReplace | 15:24 |
| *** pmallya_ has joined #heat | 15:24 | |
| inc0 | zaneb, thats update3 | 15:24 |
| inc0 | thing I'm implementing;) | 15:24 |
| *** serg_melikyan has joined #heat | 15:24 | |
| inc0 | in fact it will just modify "delete_ready" in a way that it will also check if there is replacement and replacement is set up correctly | 15:25 |
| inc0 | then return true | 15:25 |
| zaneb | ok, from what I saw you're still changing the name of the resource in the template | 15:25 |
| zaneb | but maybe it's just not done yet :) | 15:25 |
| inc0 | I will change name, but in reality it might be sha1 or whatever...I just need someting to identify resource | 15:25 |
| *** prazumovsky has joined #heat | 15:26 | |
| inc0 | name in this PoC is unique id of resource, but in reality it might as well be hash from all the data from template | 15:26 |
| inc0 | so old and new resource will have different id | 15:27 |

| inc0 | zaneb, reason for this housecleaning data is just to be able to match resource back to res it originally had | 15:44 |
| zaneb | right, but in reality you can't do that | 15:44 |
| zaneb | properties are sacrosanct | 15:45 |
| *** ananta has quit IRC | 15:45 | |
| inc0 | that was problem with my poc - I used name as unique id | 15:45 |
| *** tspatzier has quit IRC | 15:45 | |
| inc0 | now I'd use md5 of tpl definition | 15:46 |
| inc0 | thats why I could match back phys_id I have now to one I should have | 15:46 |
| zaneb | yeah, names are very much not unique | 15:46 |
| *** che-arne has quit IRC | 15:46 | |
| inc0 | yeah, I see that now;) | 15:46 |
| *** kebray has joined #heat | 15:47 | |
| inc0 | I just had to have identifier of resource that I can get straight from tpl | 15:47 |
| zaneb | I wouldn't rely on being able to store an intrinsic function in the db at all | 15:47 |
| *** kebray has quit IRC | 15:47 | |
| *** kebray has joined #heat | 15:48 | |
| inc0 | problem I had was I really need some key which would map resource definition to actual resource | 15:48 |
| zaneb | in actual Heat you'll just get a string for the property value, you'll have no way of even knowing _if_ it contains an id (or more than one) | 15:48 |
| *** achanda has joined #heat | 15:48 | |
| *** blues-man has quit IRC | 15:49 | |
| inc0 | but uuid can be mapped to resource d | 15:49 |
| inc0 | id | 15:49 |
| inc0 | and then we can check if resource_id it maps to equals that we want to have from template | 15:49 |
| openstackgerrit | Pavlo Shchelokovskyy proposed openstack/heat: Add console_urls attribute to server resource https://review.openstack.org/124463 | 15:49 |
| inc0 | so if I have 'c': GetRes('C') in db it should be represented as 'c': 'C_phys_id' | 15:50 |
| inc0 | and if I do update 'c': GetRes('D') I need to map C_phys_id to resource in stack_resources (so goal) to check if there is any work to be done | 15:51 |
| inc0 | hence this hack | 15:51 |
| inc0 | in reality I could inject goal_id into reality_db and have this solved | 15:51 |
| *** sdake has quit IRC | 15:51 | |
| zaneb | scratching my head here | 15:54 |
| zaneb | surely you resolve GetRes('D') and if the result is not the same as what you have stored in the DB (i.e. 'C_phys_id') then you need to update? | 15:55 |

| zaneb | what does it matter where the value came from? | 15:55 |
| inc0 | well, all I'm saying its solvable and it will have to be implemented in any approach | 15:55 |
| *** blues-man has joined #heat | 15:56 | |
| inc0 | I'm pretty sure this is one of worst possible solutions;) | 15:56 |

| inc0 | sorry about that, we didn't really have time to implement all the corners | 15:57 |
| zaneb | that doesn't really prove the concept to my mind | 15:57 |
| inc0 | also now I'd rewrite whole thing and start from scratch;) | 15:58 |
| pas-ha | guys, when/where was it stated that we do not support Py26 any more? https://review.openstack.org/#/c/137115/ | 15:58 |
| zaneb | pas-ha: I believe it was decided that OpenStack as a whole would drop Py2.6 in Kilo | 15:59 |
| pas-ha | ok, nice to hear :) although need to remember that for backports still.. | 16:00 |
