| tellesnobrega | I fixed the swift v3 issue, would like you both to take a look, there is a legacy v3/auth there that I didn't have time to look into | 14:02 |
| tellesnobrega | if you are ok I think we should merge it and after q3 I will see if we can remove and if needed fix it up | 14:03 |
| jeremyfreudberg | tellesnobrega, v3/auth is working afaik, i was doing proxy users stuff the other day before you put that patch out | 14:04 |
| tellesnobrega | other than that, preparing for PTG, and working on file transfer bug that appears to be a pain to solve | 14:04 |
| shuyingya | mostly working on QA for vanilla upgrade and bug fix. and help a fresher to work on keypair injection. | 14:04 |
| jeremyfreudberg | anyway, my update: several last minute patches about apiv2 from me | 14:04 |
| tellesnobrega | jeremyfreudberg, awesome, so it should be kept there | 14:04 |
| tellesnobrega | I will test it out here too, | 14:04 |
| jeremyfreudberg | tellesnobrega, yeah v3/auth is ok for now | 14:05 |
| *** julim has joined #openstack-meeting-3 | 14:05 | |
| tellesnobrega | any more news? | 14:06 |
| jeremyfreudberg | that's it for news, i guess | 14:06 |
| tellesnobrega | #topic APIv2 | 14:07 |
| *** openstack changes topic to "APIv2 (Meeting topic: sahara)" | 14:07 | |
| tellesnobrega | I guess we all have seen a storm of patches from jeremyfreudberg on APIv2 (thanks so much for that) | 14:07 |
| tellesnobrega | seems like we are in a great state to finally release APIv2 as experimental and start our process into deprecating api v1 | 14:07 |
| shuyingya | thanks for jeremy's effort | 14:08 |
| tellesnobrega | we need it merged today otherwise we need a formal FFE request | 14:08 |
| jeremyfreudberg | yup, with the client path and other final server side tweaks, things are looking good | 14:08 |
| jeremyfreudberg | s/path/patch | 14:08 |
| tellesnobrega | since tosky isn't too much around and I think that jeremyfreudberg won't enjoy +2'ing his own patch shuyingya please take some time to review so I can merge it | 14:08 |
| tellesnobrega | and we can cut Q3 today with APIv2 finally working | 14:09 |
| shuyingya | I think we can quickly merge it. If we find problem. just fix it | 14:09 |
| jeremyfreudberg | there are still a few followups for EXPERIMENTAL->CURRENT/SUPPORTED that I want to do in Rocky, but yes, everything is really working now | 14:09 |
| shuyingya | \o/ | 14:09 |
| tellesnobrega | also true | 14:09 |
| *** VW has quit IRC | 14:09 | |
| tellesnobrega | :) | 14:09 |
| tellesnobrega | ok, moving on | 14:10 |
| *** VW has joined #openstack-meeting-3 | 14:10 | |
| tellesnobrega | #topic Vanilla 2.8.2 | 14:10 |
| *** openstack changes topic to "Vanilla 2.8.2 (Meeting topic: sahara)" | 14:10 | |
| tellesnobrega | shuyingya just sent out a patch for vanilla 2.8.2 | 14:10 |
| shuyingya | It works now | 14:10 |
| tellesnobrega | what is the status of that | 14:10 |
| tellesnobrega | ? | 14:10 |
| shuyingya | I think the webUI issue can be fix in sahara-extra | 14:11 |
| shuyingya | https://issues.apache.org/jira/browse/OOZIE-2533 how about apply the workaround patch in sahara-extra? | 14:11 |
| shuyingya | I don't think remove the java dependency package in sahara side is a good way. | 14:12 |
| tellesnobrega | shuyingya, if you think it will work, I like it better than removing java dependency for sure | 14:13 |
| jeremyfreudberg | shuyingya, agree, we can just apply the workaround diff in sahara-extra | 14:14 |
| shuyingya | get lot of experience in vanilla upgrade. I think we can upgrade Hadoop 3.0 not so far. | 14:14 |
| *** VW has quit IRC | 14:14 | |
| tellesnobrega | shuyingya, that is great to hear | 14:14 |
| jeremyfreudberg | shuyingya: awesome | 14:15 |
| tellesnobrega | maybe you could prepare something to get us all the same level of expertise you have now on vanilla upgrade | 14:15 |
| tellesnobrega | couple slides maybe | 14:15 |
| shuyingya | the patch has a UT failed locally as I commented. But I think it is caused by this patch. let's see the CI result | 14:15 |
| tellesnobrega | sure | 14:16 |
| shuyingya | OK. glad to share with you | 14:16 |
| tellesnobrega | awesome, let see how it goes and we need to merge it asap (today) | 14:17 |
| shuyingya | Please review it and I will update it ASAP too. | 14:18 |
| tellesnobrega | will do | 14:18 |
| jeremyfreudberg | yes, i will try to review it asap, it's getting late in china | 14:18 |
| shuyingya | I think it is quite stable now. | 14:18 |
| tellesnobrega | awesome | 14:18 |
| jeremyfreudberg | shuyingya, about your unit test | 14:19 |
| jeremyfreudberg | it is failed for me locally too... but that is because there is some pdb statement there | 14:19 |
| jeremyfreudberg | let me try again, removing it | 14:19 |
| shuyingya | oops :( | 14:20 |
| jeremyfreudberg | running again | 14:20 |
| *** gauravsitlani has joined #openstack-meeting-3 | 14:21 | |
| jeremyfreudberg | yes, still failed | 14:21 |
| jeremyfreudberg | something about the call list is not matching | 14:21 |
| shuyingya | yes. I remember I use the pdb to trace the error. | 14:22 |
| shuyingya | forget to remove it. but I think it is weird. I need take a look at mock | 14:23 |
| jeremyfreudberg | ok, i passed it | 14:23 |
| jeremyfreudberg | it's working | 14:24 |
| tellesnobrega | jeremyfreudberg, what was wrong? | 14:24 |
| jeremyfreudberg | you can compare patchsets | 14:25 |
| shuyingya | thanks first, jeremyfreudberg | 14:25 |
| tellesnobrega | didn't see a new one | 14:25 |
| tellesnobrega | thanks jeremyfreudberg | 14:25 |
| jeremyfreudberg | i just pushed now | 14:25 |
| jeremyfreudberg | shuyingya, that passes locally for me | 14:25 |
| *** alexchadin has joined #openstack-meeting-3 | 14:25 | |
| shuyingya | oops | 14:26 |
| tellesnobrega | that makes sense, it does have that call | 14:26 |
| shuyingya | thanks jeremyfreudberg | 14:27 |
| tellesnobrega | awesome, lets wait for the tests and merge it | 14:27 |
| *** psachin has joined #openstack-meeting-3 | 14:27 | |
| jeremyfreudberg | np | 14:27 |
| jeremyfreudberg | is that it for this topic? (and i will review the rest quickly) | 14:27 |
| tellesnobrega | yes | 14:28 |
| tellesnobrega | #topic Dublin PTG and Doc day | 14:28 |
| *** openstack changes topic to "Dublin PTG and Doc day (Meeting topic: sahara)" | 14:28 | |
| tellesnobrega | I was talking with tosky yesterday and he suggested that we do a prep doc day before PTG so we don't waste time thee | 14:28 |
| tellesnobrega | what do you think? | 14:29 |
| shuyingya | I have applied the PTG tsp. let's wait the response. :) | 14:29 |
| tellesnobrega | that is awesome shuyingya :) | 14:29 |
| jeremyfreudberg | shuyingya, that is great | 14:29 |
| tellesnobrega | hopefully you will be there | 14:29 |
| shuyingya | That would be great If I can be there. Let's talk about tellesnobrega and tosky's idea | 14:30 |
| tellesnobrega | the idea is to save time from PTG | 14:30 |
| jeremyfreudberg | i agree that prep doc day probably makes sense -- what should we be looking for during prep? i mean, most docs are old and weird anyway, what is the priority kind of problem to fix | 14:30 |
| tellesnobrega | that is the main idea, we don't know what to look for | 14:31 |
| tellesnobrega | the prep day is to get a good look at it and see the main problems so we can get a jump start | 14:31 |
| *** psachin has quit IRC | 14:32 | |
| jeremyfreudberg | right | 14:32 |
| jeremyfreudberg | make sense | 14:32 |
| tellesnobrega | what is the best day (weekday) for you both? | 14:32 |
| *** psachin has joined #openstack-meeting-3 | 14:33 | |
| jeremyfreudberg | mondays and wednesdays are okay | 14:33 |
| tellesnobrega | that works for you too shuyingya? | 14:33 |
| jeremyfreudberg | of course coordinating time zone is tricky | 14:34 |
| *** markvoelker has joined #openstack-meeting-3 | 14:34 | |
| shuyingya | I would say anytime is ok, haha | 14:34 |
| tellesnobrega | jeremyfreudberg, it is, but we can try to do it in steps, we coordinate parts of doc for each of us and shuyingya can start before us and once we are up we can continue | 14:34 |
| jeremyfreudberg | true | 14:35 |
| shuyingya | sounds great | 14:35 |
| tellesnobrega | cool, I will start organizing it and send out an email on it | 14:36 |

| *** openstack changes topic to "PTL Elections (Meeting topic: sahara)" | 14:37 | |
| tellesnobrega | you probably have seen that PTL election self nomination starts next week | 14:37 |
| tellesnobrega | does anyone intend to run this cycle? | 14:38 |
| jeremyfreudberg | i am not in the position time-wise or job-wise to PTL, it is on my mind, probably you can see it happening for T or U release, but not now | 14:39 |
| tellesnobrega | jeremyfreudberg, good | 14:40 |
| shuyingya | tellesnobrega really do a great job on this position. | 14:40 |
| tellesnobrega | thanks shuyingya | 14:40 |
| jeremyfreudberg | yes, i hope telles will nominate himself and keep doing good | 14:40 |
| tellesnobrega | I will be running since I believe no one else is doing | 14:41 |
| tellesnobrega | it | 14:41 |
| shuyingya | I would be nice if you still nominate yourself :) | 14:41 |
| tellesnobrega | but my idea is to get someone else in the position soon as well | 14:41 |
| shuyingya | +1 | 14:41 |
| tellesnobrega | so we can take turns, help each other and prepare leadership | 14:41 |
| tellesnobrega | SotK, I'm happy to hear that jeremyfreudberg intends to be there soon | 14:42 |
| tellesnobrega | I fully support it :) | 14:42 |

| jeremyfreudberg | https://review.openstack.org/#/c/536002/ and https://review.openstack.org/#/c/537666/ are two of my patches, they really should go into queens-3, so please finish reviewing them | 14:43 |
| jeremyfreudberg | this is more api stuff on the server-side | 14:44 |
| tellesnobrega | awesome, looking at the one I didn't look now | 14:44 |
| jeremyfreudberg | both of them were extensively used by me in testing apiv2, so they should work fine | 14:44 |
| tellesnobrega | perfect :) | 14:44 |
| jeremyfreudberg | more importantly, tellesnobrega please approve force delete when you can, that definitely needs to go into queens-3 | 14:45 |
| tellesnobrega | yes | 14:45 |
| jeremyfreudberg | thanks shuyingya for your worfklow+1 s | 14:45 |
| tellesnobrega | done, force delete is coming in hot | 14:46 |

| jeremyfreudberg | thanks shuyingya | 14:47 |
| *** sgrasley1 has joined #openstack-meeting-3 | 14:47 | |

| tellesnobrega | yes | 14:48 |
| jeremyfreudberg | i guess we will consider FFE for hbase on sie, shuyingya | 14:48 |

| *** rmcall has joined #openstack-meeting-3 | 14:49 | |
| shuyingya | sorry, what's fullname of FFE? | 14:50 |
| jeremyfreudberg | sorry, feature freeze exception | 14:50 |
| tellesnobrega | feature freeze exception | 14:50 |
| jeremyfreudberg | if you have time to work on it in the next few weeks, we will help you get it in | 14:50 |
| jeremyfreudberg | if you don't have time, that's okay too | 14:50 |
| shuyingya | that would be great. I think we can put it off. really busy for downstream tasks | 14:51 |
| shuyingya | But I promise I will finish it asap | 14:51 |
| jeremyfreudberg | great, thanks again for contributions shuyingya | 14:52 |
| tellesnobrega | awesome, thanks shuyingya | 14:52 |
| shuyingya | np | 14:52 |
| tellesnobrega | and we fully understand that balancing upstream and downstream is extremely hard | 14:52 |
| shuyingya | thanks for your understanding :) | 14:52 |
| tellesnobrega | no problem at all | 14:53 |
| jeremyfreudberg | ugh, infra problems on the gate, everything will need recheck later | 14:54 |
| tellesnobrega | jeremyfreudberg, I will make sure we get rechecked | 14:55 |
| *** janzian has joined #openstack-meeting-3 | 14:55 | |
| jeremyfreudberg | "please stand by and don't needlessly recheck job" is the advice for now | 14:55 |
| tellesnobrega | sure | 14:55 |
| tellesnobrega | will wait as much as I can | 14:56 |
| tellesnobrega | so we don't overload infra | 14:56 |
| jeremyfreudberg | btw, i will be offline for a good part of day | 14:57 |
| jeremyfreudberg | unfortunately | 14:57 |
| *** alexchadin has quit IRC | 14:57 | |

| jeremyfreudberg | after those 6 hours if the fires are not put out i will help | 14:58 |

| haleyb | mlavalle: yes, lets | 15:10 |
| mlavalle | I can start looking at it if you don't have badnwidth to work on it | 15:11 |
| mlavalle | it doesn't seem that Swami is going to make more progress any time soon | 15:11 |
| haleyb | i had been busy downstream, but have some cycles now to look, so i will try and reproduce it | 15:11 |
| mlavalle | haleyb: That's perfect. Don't want to put undue pressure on you. Please feel free to oing me if you need help | 15:13 |
| haleyb | mlavalle: ok, i'll oing you :) | 15:14 |

| mlavalle | Swami seems to be busy also with Suse downstream work | 15:16 |
| mlavalle | so maybe it is time to distribute some of his tasks | 15:16 |
| mlavalle | do you want me to start collecting the list of dvr bugs for this meeting? | 15:17 |
| haleyb | mlavalle: i can do it now that i know Swami is busy | 15:17 |
| mlavalle | perfect | 15:18 |

| mlavalle | I think it would have to be in the context of what a broader conversation on what are the next steps for DVR | 15:29 |
| haleyb | mlavalle: sure | 15:30 |
| david_chou1 | I would like to, I will talk with my manager to see whether it is possible or not. | 15:30 |

| SumitNaiksatam | ok great | 18:08 |
| annakk | so are we planning a demo of both drivers with focus on service chaining? | 18:09 |
| SumitNaiksatam | annakk: i am not so sure about the part on service chaining | 18:09 |
| SumitNaiksatam | demo of the two drivers is something we can certainly attempt | 18:09 |
| SumitNaiksatam | we can start with your work since its something new, at least as a driver for GBP | 18:10 |
| SumitNaiksatam | rkukura: tbachman: thoughts? | 18:10 |
| annakk | without service chaining its weird to put this in NFV track, no? | 18:10 |
| *** julim has quit IRC | 18:10 | |
| SumitNaiksatam | annakk: ah okay, i would say lets first see how the abstract shapes up | 18:10 |
| SumitNaiksatam | we can accordingly decided where to put it | 18:11 |
| SumitNaiksatam | i didnt necessarily have the NFV theme central in my mind | 18:11 |
| annakk | ok | 18:11 |
| tbachman | SumitNaiksatam: were we looking at one talk, or multiple? | 18:11 |
| rkukura | is the idea to provide an update on the project status and maybe discuss what’s next? | 18:11 |
| SumitNaiksatam | tbachman: would be great if we had multiple, but i guess start with the outline of the first one :-) | 18:11 |
| tbachman | sounds good | 18:11 |
| SumitNaiksatam | but it very often happens that we start with one and then as we go along we realize that we have a number of things to talk about | 18:12 |
| SumitNaiksatam | tbachman: so agree | 18:12 |
| SumitNaiksatam | annakk: the NFV theme connection would have been strong if your driver was doing something in that domain | 18:12 |
| annakk | there is such plan, not sure it will materialize till May | 18:13 |
| SumitNaiksatam | annakk: its okay to put forward looking things | 18:14 |
| SumitNaiksatam | it doesnt have to be absolutely ready | 18:14 |
| SumitNaiksatam | i think even a conceptual design is fine (as long as its coherent) | 18:14 |
| SumitNaiksatam | annakk: but up to you, whatever you feel comfortable | 18:14 |
| annakk | but on aim side is there some service chaining to show? | 18:14 |
| SumitNaiksatam | annakk: much of what we did with the apic drivers has already been shown before | 18:15 |
| SumitNaiksatam | so if you were to show something with NSX, we could show those things again | 18:15 |
| annakk | ok | 18:15 |
| SumitNaiksatam | but by itself, it might not make much sense | 18:15 |
| annakk | understood | 18:16 |
| *** lpetrut has quit IRC | 18:16 | |
| SumitNaiksatam | rkukura: sorry i missed your earlier comment | 18:16 |
| annakk | i might reach out for help to you/gary about the abstract since i've never done an openstack proposal before | 18:16 |
| SumitNaiksatam | rkukura: i agree, we should discuss that | 18:17 |
| SumitNaiksatam | rkukura: but i am thinking that by itself it might not make a strong case for us being accepted for the talk | 18:17 |
| SumitNaiksatam | rkukura: by “that” i meant “project update" | 18:18 |
| SumitNaiksatam | if we dont have anything else, we can still use that though :-) | 18:18 |
| SumitNaiksatam | annakk: sure, i dont think there is a set pattern, feel free to express yourself :-) | 18:19 |
| SumitNaiksatam | (i meant in the abstract) | 18:19 |
| rkukura | agreed, but we need some way to be relevant to the OpenStack community, since we aren’t an official project (at the moment) | 18:19 |
| SumitNaiksatam | rkukura: completely agree | 18:19 |
| SumitNaiksatam | annakk: we were also discussing about how the larger goal of this project was to tackly the notion of policy in general | 18:20 |
| *** rmcall has quit IRC | 18:20 | |
| SumitNaiksatam | not limited to just networking, but across compute and storage domain also | 18:20 |
| rkukura | I’d hope that if we do get the opportunity to present, we can use it to attract interest/participation from the community | 18:20 |
| SumitNaiksatam | and also across technologies, virtual, plysical, container, etc | 18:20 |
| SumitNaiksatam | rkukura: i agree, very important point, and should definitely be our goal, to promote the project so as to attract more people to work with us | 18:21 |
| *** sambetts is now known as sambetts|afk | 18:22 | |
| SumitNaiksatam | okay, if nothing more on this, we can move to the next topic | 18:22 |
| SumitNaiksatam | #topic DB writer pattern quirks | 18:22 |
| *** openstack changes topic to "DB writer pattern quirks (Meeting topic: networking_policy)" | 18:22 | |
| SumitNaiksatam | so last week i made an attempt to explain this | 18:23 |
| SumitNaiksatam | here is a specific example: | 18:23 |
| SumitNaiksatam | #link https://review.openstack.org/#/c/532277/1..4/gbpservice/neutron/tests/unit/services/sfc/test_aim_sfc_driver.py | 18:23 |
| SumitNaiksatam | search for: test_vrf_update | 18:23 |
| SumitNaiksatam | L661 on left side, L763 or right side | 18:24 |
| SumitNaiksatam | so firstly, if you see L670 on the left side | 18:24 |
| SumitNaiksatam | we are getting a reference to a DB object, and then using it in L674 | 18:25 |
| SumitNaiksatam | this created issues, since this was not wrapped in a transaction | 18:25 |
| SumitNaiksatam | so if you see on L774 on the RHS, we added the transaction block | 18:26 |
| *** raildo has quit IRC | 18:27 | |
| *** raildo has joined #openstack-meeting-3 | 18:27 | |
| *** mlavalle has left #openstack-meeting-3 | 18:27 | |
| SumitNaiksatam | the processing now proceeds to L777 which in turn calls _add_network_mapping_and_notify L3387 in #link https://review.openstack.org/#/c/532277/4/gbpservice/neutron/plugins/ml2plus/drivers/apic_aim/mechanism_driver.py | 18:27 |
| SumitNaiksatam | out here on L3389, a writer pattern is used | 18:29 |
| SumitNaiksatam | but it does not create a new sub-transaction | 18:29 |
| SumitNaiksatam | so the test case which was originally calling this, actually mocks the notify on L3392, and raises an exception | 18:29 |
| SumitNaiksatam | if instead of using the writer pattern on L3389, we had use the older session.begin(subtransactions=True) pattern, the netwrok_mapping which is happening in the L3390, would have never gotten persisted | 18:31 |
| SumitNaiksatam | however, going back to #link https://review.openstack.org/#/c/532277/1..4/gbpservice/neutron/tests/unit/services/sfc/test_aim_sfc_driver.py | 18:31 |
| SumitNaiksatam | on LHS if you see L674, it asserts that the exception is raised, but it actually eats up the exception | 18:32 |
| SumitNaiksatam | hence the network_mapping done earlier gets persisted | 18:32 |
| SumitNaiksatam | and the test fails | 18:33 |
| SumitNaiksatam | i am sure now i have managed to confuse you way more than what i had last week :-) | 18:33 |
| SumitNaiksatam | applause please! | 18:33 |
| tbachman | lol! | 18:34 |
| * tbachman does his best golf clap | 18:34 | |
| SumitNaiksatam | tbachman: thanks :-) | 18:34 |
| tbachman | heh | 18:34 |
| SumitNaiksatam | happy to discuss this particular case further, but if i had to drive a couple of takeways from this | 18:34 |
| SumitNaiksatam | 1. be careful when you assert and exception, because that call will eat the exception, so you can no longer except the original rollback to happen | 18:35 |
| SumitNaiksatam | 2. in places like L3389 in #link https://review.openstack.org/#/c/532277/4/gbpservice/neutron/plugins/ml2plus/drivers/apic_aim/mechanism_driver.py | 18:36 |
| SumitNaiksatam | the use of: with context.session.begin(subtransactions=True) | 18:36 |
| SumitNaiksatam | would be a better choice, assumign we always know that its going to be nested within an outside: with context_manager.writer(context) | 18:37 |
| SumitNaiksatam | i meant to say assert *an* exception in (1), not “assert and exception” | 18:38 |
| SumitNaiksatam | to extend (2) further, the “with context.session.begin(subtransactions=True)” can be nested within a writer or reader block | 18:39 |
| annakk | i wonder if this can be relevant? https://review.openstack.org/#/c/433758/ | 18:39 |
| annakk | i vaguely remember similar problems | 18:39 |
| *** lyan has quit IRC | 18:39 | |
| SumitNaiksatam | this is helpful in the cases where you do want to create a new subtranction (the new subtransaction will immediately rollback when the context exits, if there is a failure) | 18:40 |
| SumitNaiksatam | annakk: could be | 18:40 |
| SumitNaiksatam | but basically, i would like to avoid using any flush | 18:41 |
| SumitNaiksatam | it should not be needed, at least in our code | 18:41 |
| rkukura | every query does a flush, doesn’t it? | 18:41 |
| rkukura | you mean explicit flush | 18:41 |
| SumitNaiksatam | rkukura: yes explicit flush in our code | 18:41 |
| SumitNaiksatam | flush or even refresh | 18:42 |
| SumitNaiksatam | in the past we have reluctantly done that | 18:42 |
| *** yamamoto has quit IRC | 18:42 | |
| SumitNaiksatam | but ideally we should not need to do it (assume there are no bugs in the underlying oslo_db code) | 18:42 |
| SumitNaiksatam | and we are undertanding its usage correctly :-) | 18:42 |
| *** diablo_rojo has quit IRC | 18:43 | |
| SumitNaiksatam | happy to discuss this particular case further if there are questions/comments. or we can review the patch and come back to it next week | 18:44 |
| SumitNaiksatam | annakk: thanks for the pointer, at least i hadnt noticed it | 18:44 |
| SumitNaiksatam | need to check if its still in place or if they have reverted it | 18:44 |
| SumitNaiksatam | #topic Open Discussion | 18:45 |
| *** openstack changes topic to "Open Discussion (Meeting topic: networking_policy)" | 18:45 | |
| annakk | SumitNaiksatam: yes I think they added default behavior later on but I can't find it | 18:45 |
| SumitNaiksatam | annakk: okay | 18:45 |
| SumitNaiksatam | anything else we need to discuss today? | 18:45 |
| rkukura | SumitNaiksatam: Do you have guidance on whether all new code should be using the new API, or if there are cases where context.session.begin() really should be used? | 18:46 |
| annakk | I just want to mention I started to test pike, but stack on some infra issues for now, unrelated to the pike changes | 18:46 |
| SumitNaiksatam | annakk: okay good to know, keep us update on how it goes | 18:46 |
| annakk | sure | 18:46 |
| rkukura | I admit I am not familar enough with Ivar’s patch yet to have followed the above discussion in realtime | 18:46 |
| SumitNaiksatam | rkukura: yes, basically learnt by experience here | 18:47 |
| SumitNaiksatam | so my understanding is that the writer pattern can be nested | 18:47 |
| SumitNaiksatam | and it all works fine | 18:47 |
| SumitNaiksatam | the big difference is that, a new subtransaction is not created when nesting happens | 18:48 |
| SumitNaiksatam | so if you expected something as a result of the (previously used) subtransaction to commit or rollback, it may not behave the same way | 18:48 |
| SumitNaiksatam | for new code, i would prefer to use the older pattern (i.e. subtransactions=True) if you are absolutely sure that the code would not be called at the top level of the transaction | 18:50 |
| SumitNaiksatam | but when in doubt, use the newer writer pattern | 18:50 |
| SumitNaiksatam | there are almost 4 levels of DB abstractions that we are navigating here | 18:51 |
| SumitNaiksatam | GBP -> neutron -> oslo_db -> sqlalchemy -> mysql ! | 18:51 |
| rkukura | it seems we should be using readers where possible, and that they should act like writers when nested inside a writer transaction. Is that the case? | 18:51 |
| annakk | almost 4 :) | 18:51 |
| SumitNaiksatam | rkukura: that is correct | 18:52 |
| SumitNaiksatam | reader will get elevated | 18:52 |
| SumitNaiksatam | when nested | 18:52 |
| SumitNaiksatam | if you nest a writer inside a reader, the session that was used for the reader will now change | 18:54 |
| SumitNaiksatam | and so will the transaction | 18:54 |
| SumitNaiksatam | the transaction is gauranteed to be preserved only when either a reader or writer is nested within a top level writer | 18:54 |
| SumitNaiksatam | time check, 5 minutes | 18:56 |
| rkukura | so what is the advantage of using the old session.begin? | 18:56 |
| *** yamahata has joined #openstack-meeting-3 | 18:56 | |
| SumitNaiksatam | if your code is written with complete understanding of the newer approach, there is no advantage | 18:57 |
| annakk | do we know of areas with missing code coverage where such problems can be revealed, if exist? | 18:58 |
| annakk | *test coverage* | 18:58 |
| SumitNaiksatam | annakk: tough question :-) | 18:58 |
| annakk | :) | 18:59 |
