| notmyname | good morning | 17:08 |
| *** pberis has quit IRC | 17:09 | |
| mahatic | good morning | 17:09 |
| mahatic | notmyname, just letting you know, I'm not writing a class, just defining methods (in a new file in swift.common) and importing them (for OPTIONS common) | 17:11 |
| notmyname | mahatic: ok, I'm interested to see it when you get to a "push to gerrit" point :-) | 17:11 |
| mahatic | :) alright | 17:12 |
| mahatic | notmyname, sorry if i'm doing too many rounds on this. But it's a lil confusing. If i want to write a class, in storage nodes all the http verbs are under a class which inherits "object". Now am i supposed to do a multiple inheritance? | 17:14 |
| mahatic | a class for common OPTIONS | 17:15 |
| *** gyee has joined #openstack-swift | 17:23 | |
| notmyname | mahatic: you wouldn't need multiple inheritance. you'd have something like: | 17:24 |
| notmyname | mahatic: class Base(object) | 17:24 |
| notmyname | mahatic: class SomethingSpecific(Base) | 17:24 |
| mahatic | notmyname, nevermind | 17:24 |
| mahatic | yeah | 17:24 |

| mahatic | notmyname, I will submit the patch and for reviews (or thrashing, whichever the case ;) ) | 17:36 |

| openstackgerrit | Mahati proposed openstack/swift: OPTIONS verb implemented for object server. https://review.openstack.org/140103 | 17:58 |
| *** exploreshaifali has quit IRC | 17:59 | |
| notmyname | mahatic: want to talk in here about it or keep it in gerrit? | 18:01 |
| mahatic | notmyname, anything is fine. If it's long, probably here. and shorter ones in gerrit? | 18:02 |
| notmyname | mahatic: ok | 18:02 |
| notmyname | mahatic: since you changed all the Controller classes to inherit from BaseStorageServer, that means they all have getOPTIONS() right? | 18:04 |
| mahatic | notmyname, yeah | 18:04 |
| notmyname | mahatic: so why implement OPTIONS if all it does is call getOPTIONS? why not have OPTIONS in the base class? | 18:05 |
| mahatic | notmyname, hmm, i thought what if storage nodes need to respond with a different info - ? | 18:06 |
| notmyname | mahatic: yes they will, be there will be a better way to do it. and, importantly, right now they're all the same | 18:06 |
| mahatic | notmyname, okay. I will do away with the call then. Will make changes coming up accordingly | 18:07 |
| notmyname | mahatic: does that make sense to you? | 18:07 |
| mahatic | notmyname, yeah. Though not very clear about the better way, but i'm thinking i should be able to figure out as i move ahead | 18:08 |
| notmyname | mahatic: heh ok :-) | 18:08 |
| notmyname | mahatic: mostly I'm looking for a good baseline of the basic functionality before we get into more specifics | 18:09 |
| mahatic | notmyname, yup sure. Now that makes sense :) | 18:09 |
| notmyname | mahatic: I'm going to mark your patch WIP in gerrit | 18:14 |
| notmyname | since you're still working on it and it's not ready for reviews yet | 18:15 |
| mahatic | notmyname, okay | 18:15 |

| notmyname | swift team meeting in 20 minutes | 18:41 |
| notmyname | mahatic: that's the path part of the URL on the reuqest | 18:41 |
| mahatic | notmyname, okay. Maybe i'll push that test to gerrit along with the other changes and then you'll take a look? | 18:42 |
| mahatic | I just wanted to confirm if that will be all in tests | 18:43 |
| notmyname | mahatic: well, you need to make sure it passes for you locally first | 18:43 |
| notmyname | before pushing to gerrit | 18:43 |

| bgmccollum | so...versioned writes, under a concurrent write load...is it conceivable that some previous versions might get lost? | 23:09 |
| *** nellysmitt has joined #openstack-swift | 23:12 | |
| bgmccollum | cause thats what im seeing ;) | 23:12 |
| notmyname | bgmccollum: yes | 23:12 |
| notmyname | bgmccollum: although I take issue with "lost" ;-) | 23:12 |
| notmyname | bgmccollum: basically, at the time of the 2nd write, the current version is copied. but if there is another existing write happening, that one won't be versioned | 23:13 |
| bgmccollum | well, its break Heat's OS::Heat::SwiftSignal wait condition thinggy | 23:13 |
| bgmccollum | but the fact that Heat uses version writes seems kinda...hacky | 23:14 |
| notmyname | ya, that is interesting. I wonder why | 23:14 |
| *** nellysmitt has quit IRC | 23:16 | |
| bgmccollum | basically, it grabs the current version, and previous versions, and iters through them, counting up the unique IDs, and if it has at least the minimum, then they Heat template proceeds. so if you have two signaling around the same time, one gets lost, and you never meet your minimum to proceed. :( | 23:16 |
| notmyname | that...doesn't sound right | 23:17 |
| bgmccollum | doesn't sound right...or doesn't sound like a good idea? :p | 23:18 |
| notmyname | the latter | 23:18 |
| bgmccollum | i agree | 23:19 |
| notmyname | however, I don't fault them for assuming the way it works. we should have better docs about what versioned writes do. or, in this case, what they don't do | 23:20 |
| bgmccollum | https://github.com/openstack/heat/blob/master/heat/engine/resources/swiftsignal.py | 23:20 |
| notmyname | still, using the state of an object in an eventually consistent storage system when you are continually overwriting that object isn't a good pattern. regardless of some feature named "versioned writes" or not | 23:21 |
| bgmccollum | its not so much the state of the object, they literally iter through the current version, and all previous versions to build a list of all signals | 23:22 |
| bgmccollum | and filter out duplicates for the same ID | 23:22 |
| bgmccollum | and sum | 23:22 |
| notmyname | I'm not sure what a "signal" is | 23:22 |
| bgmccollum | sorry...think if it at a post, with an ID it | 23:22 |
| bgmccollum | like...im done doing my thing, and my ID is 1 | 23:22 |
| bgmccollum | im also done doing my thing, and my ID is 2 | 23:22 |
| bgmccollum | but, its writing to the same object | 23:23 |
| bgmccollum | it appears they are exploiting versioned writes to as if it was a log... | 23:23 |
| bgmccollum | think of it like this. the current version of the object represents the last message logged to a log file, and the previous versions are previous messages in the log file... | 23:25 |
| bgmccollum | and relying on the previous versions to making some determination if an even happened or not | 23:26 |
| bgmccollum | s/even/event | 23:26 |
| bgmccollum | either way...the heat implementation is...no bueno | 23:27 |
