| ho | notmyname: hello :-) | 00:02 |
| notmyname | ho: when you get a chance today (if you do), can you take a look at https://bugs.launchpad.net/swift/+bug/1451710 ? | 00:03 |
| openstack | Launchpad bug 1451710 in OpenStack Object Storage (swift) "http 503 error reported in swift component after changing the local" [Undecided,New] | 00:03 |
| notmyname | redbo: are you at gophercon this week? | 00:03 |
| redbo | Yeah, after tomorrow | 00:03 |
| torgomatic | notmyname: I have not looked at that in the slightest; it's not related to anything I'm working on. Sounds like a bug in the ring-builder CLI; by the time you hit the .set_weight() method of the builder, there's no opportunity to make that goof anymore | 00:03 |
| ho | notmyname: Ok, I will check it. | 00:04 |
| notmyname | torgomatic: ah ok | 00:04 |
| notmyname | ho: thanks | 00:04 |

| jith_ | hi all.. what is the difference between user auth token and composite token? | 06:28 |
| *** sanchitmalhotra has joined #openstack-swift | 06:36 | |
| *** sanchitmalhotra1 has quit IRC | 06:38 | |
| mattoliverau | jith_: auth token is what you as a user will use to login. A copisite token is a second token that a service using swift might use. | 06:43 |

| jith_ | mattoliverau: Thanks.. all objects corresponding to one project will save in one account in swift.. is it so? | 07:30 |
| jith_ | all other services use composite token or only glance and cinder uses the composite token? | 07:32 |
| mattoliverau | jith_: yes, in general. if setting up services like glace, you can set that up in different ways. But generally speaking a project/tennent maps to a swift account. | 07:33 |
| mattoliverau | You can set up services to connect as a partiular user, use the projects account, or use a composite key (users key but a services key) depending on your setup and what you want to do. | 07:34 |
| mattoliverau | *users key and a services key == composite key | 07:35 |
| *** jistr has joined #openstack-swift | 07:37 | |
| *** jordanP has joined #openstack-swift | 07:41 | |
| jith_ | mattoliverau: thanks a lot.. is it i can either connect the swift using composite key or as a user using some account? i am sorry if i am wrong.. i am beginner | 07:46 |
| mattoliverau | jith_: this might help: http://docs.openstack.org/developer/swift/overview_auth.html#openstack-service-using-composite-tokens and might be more outdated now but this is good also: http://specs.openstack.org/openstack/swift-specs/specs/done/service_token.html | 07:48 |

| jon1111 | If I have a 4 replica ring and half of the cluster is down (region with half of the replicas). Would DELETE of objects fail? (network part) | 16:54 |
| notmyname | jon1111: with 4 replicas, you have a quorum of 3 (4 // 2 + 1 = 3) | 16:55 |
| notmyname | jon1111: so, yes. PUTs and DELETEs would fail | 16:55 |
| notmyname | jon1111: except.... | 16:55 |
| clayg | 404 is the new 204 | 16:56 |
| *** tongli has quit IRC | 16:56 | |
| notmyname | jon1111: they will fail if swift can't find *any* 3 nodes to accept the operation. if the primary locations aren't available, swift will choose handoffs. so even if you get 2 primaries and 1 handoff, that's ok | 16:56 |
| jon1111 | OK, thanks, that is what I expected. | 16:56 |
| *** tongli has joined #openstack-swift | 16:56 | |
| jon1111 | Yep, they fail with a 4XX, I guess. Then later when the link comes up they will get deleted? | 16:57 |

| portante | notmyname: but coroutines are NOT asynchronous! | 19:17 |
| portante | this is one of the fundamental problems with cooperative scheduling: folks think they are operating asynchronously but they are not | 19:17 |
| portante | oh well, beating a dead horse | 19:18 |
| clayg | portante: a processor isn't asynchronous either - and yet somehow we managed multi-tasking operating systems even on single core machines? | 19:18 |
| portante | I am not sure that is the same thing | 19:19 |
| portante | multiple cores mean async execution | 19:19 |
| portante | offloading of I/O is asynchronous, but the non-blocking method is not about performing operations asynchronously, it is about the kernel telling user space that some operation would block, but if it does not say it would block, it is still free to block it | 19:21 |
| clayg | I think the cooperative scheduling gives a sufficiently effective "appearence" of asynchronous operation - just like mult-tasking operating systems are effective at making it looks like it's doing multiple things on a single core? | 19:21 |
| portante | async I/O is about describing the I/O operation that user spaces wants to happen, queuing to the OS so that it will happen asynchrously to the thread of execution | 19:21 |
| clayg | oic - yeah we're talking about different things :) | 19:21 |
| clayg | not surprised - I agree with you :D | 19:21 |
| portante | this is what I think is the exact problem with this space, the terminology is not used consistently by the core creators, so peps like this continue to keep the waters muddy | 19:22 |
| clayg | oh lol - i get it - the module is the worst name ever for something that basically wraps up non-blocking io in an event reactor - yeah too funny | 19:23 |
| clayg | yeah rofl | 19:23 |

| notmyname | portante: 4k object PUTs with a concurrency of 16: SMR@37/s; PMR@122/s | 21:18 |
| portante | so little less than 1/3 of the performance | 21:20 |
| portante | but is there another measure? Like PUTs per square inch of rack space or something? | 21:21 |
| portante | ;) | 21:21 |
| hrou | Ah, very interesting, planning on trying with larger objects ? | 21:21 |
| notmyname | hrou: yes. but next I'm going to do reads. I expect them to be worse | 21:22 |

| notmyname | concurrency of 32, same object sizes: PMR@178/sec; SMR@41/sec | 21:42 |
| notmyname | portante: hrou: ^ | 21:42 |
| hrou | Just about the same as your right tests perf wise | 21:44 |
| hrou | *write tests - interesting! | 21:44 |
| notmyname | no, that was writes | 21:44 |
| notmyname | haven't done reads yet | 21:44 |
| hrou | Ah ! Sorry I see you just x2 the concurrency. | 21:45 |
| notmyname | right | 21:46 |
| notmyname | meanwhile the PMR drives had gone on to also run the 64 and 128 concurrency tests. | 21:46 |
| notmyname | anyway, off to write the read test code | 21:47 |
| hrou | If those workloads end up on the same object server -> disk, that's when I'd expect to see the worst performance. I believe the SMR drives handle the sequential read requirements by maintaining a mapping in memory, but once that's full, it needs to defragment so to speak. | 21:47 |
| hrou | That's awesome ! Thanks, you're likely the first (or just about) first person to be doing swift -> smr tests, Feel special ? : ) | 21:48 |
| notmyname | not really ;-) | 21:48 |

| mattoliverau | Cool, jury duty tho, that's kinda exciting (saying that cause I've never had to do it). | 23:25 |
| notmyname | it's an interesting experience | 23:27 |
| notmyname | I've done it once before | 23:27 |
| notmyname | on the one hand, it's (at least symbolically) a huge part of our national duty, I think. like voting | 23:28 |
| notmyname | on the other, it's tedious, boring, inconvenient, and most people try really hard to get out of it | 23:28 |
| *** hrou has joined #openstack-swift | 23:32 | |
| *** annegentle has quit IRC | 23:34 | |
| mattoliverau | yeah, it probably is mainly boring, I'm probably just seeing the glamous side TV/movie-ified side which doesn't really exist :) | 23:35 |
| notmyname | well, you have to take off work, go somewhere else, sit around and wait, listen to a case, make a decision (those last 2 can take days), and get paid about $10 per day for it | 23:37 |
| notmyname | for people who don't have good employers or work hourly, it can be a really big hardship | 23:38 |
| clayg | notmyname: I think you're getting a bit hit-n-miss on the priority review dashboard? | 23:38 |
| notmyname | clayg: ah? perhaps so :-) | 23:38 |
| notmyname | I'll admit I haven't kept on top of it | 23:38 |
| notmyname | I did spend all day yesterday in LP though ;-) | 23:38 |
| *** classicsnail has quit IRC | 23:38 | |
| mattoliverau | notmyname: yeah, actually that could really suck for people, $10 a day, and what if its a large trial. | 23:39 |
| clayg | notmyname: We only expect perfection from you at all times | 23:39 |
| notmyname | clayg: the dashboard with the starred patches or the priority reviews wiki page? | 23:39 |
| clayg | mattoliverau: well I think there's also some laws that say cooprerations can't doc your salary - so the judge may excuse you if it's going to be a long trial. | 23:40 |
| clayg | notmyname: starred patches > wiki page | 23:40 |
| notmyname | on the dashboard, that huge list of stuff that needs one more +2 to land is a good place to start :-) | 23:40 |
| clayg | acctually with the dashboard - I don't think we need to have a *seperate list* of patches? | 23:40 |
| klrmn | one would think jury duty, while being a responsibility, would at least pay minimum wage | 23:40 |
| clayg | notmyname: ok thanks! | 23:40 |
| *** classicsnail has joined #openstack-swift | 23:40 | |
| notmyname | clayg: yeah, 1 list >> 2 lists | 23:41 |
| clayg | klrmn: maybe if the defendent had to pay for it? | 23:41 |
| notmyname | clayg: yikes. state should pay. I don't want to be sued and forced to pay for the jury that may or may not find me guilty. also, can I pay more for my jury to get a better outcome? ;-) | 23:42 |
| mattoliverau | lol | 23:42 |
| klrmn | seems to me, if you want to cut down on frivolty suits, the prosecution should pay | 23:42 |
| clayg | klrmn: notmyname: looser pays! | 23:43 |
| klrmn | in criminal cases, that'd be the gov't anyway | 23:43 |
| notmyname | klrmn: and then only the rich can seek court approved justice. | 23:43 |
| klrmn | point | 23:43 |
| hrou | Most large employers will pay for up to 3 weeks, but after generally not; Yea I've had this debate with a lot of folks, one would think there should be a law that forces employeers to pay no longer how long the trial is | 23:43 |
| clayg | you two *sure* you want to go to court? I hear jurors rates are going up? | 23:44 |
| notmyname | you can already sue your accuser for court costs in many cases if you are found not guilty. the state should pay at least min wage for juries | 23:44 |
| notmyname | hrou: especially since you go to jail if you don't serve! so the choice can be jail or lose your job | 23:44 |
| notmyname | clayg: I'll update the dashboard ASAP | 23:45 |
| hrou | Right though that's where the art of getting out of it comes into play, that is the various excuses you can use, really depends on the judge, I know someone who simply said he was starting a new job and thought it would reflect badly on him, and apparently that was sufficient enough and he was let go : ) | 23:46 |
| notmyname | maybe tonight. maybe something to do while waiting for whatever happens tomorrow ;-) | 23:46 |
| notmyname | hrou: FWIW, reading the 4KiB objects is pretty much the same for SMR and PMR drives. that surprised me | 23:47 |
| notmyname | I'll be testing with bigger objects next | 23:47 |
