bswartz#topic Networking BP15:02
*** openstack changes topic to "Networking BP (Meeting topic: manila)"15:02
*** KenD has joined #openstack-meeting-alt15:02
* rushiagr started remembering about it only at the start of the meeting15:02
bswartz#link https://blueprints.launchpad.net/manila/+spec/join-tenant-network15:02
*** katyafervent has joined #openstack-meeting-alt15:03
bswartzso this is the culmination of the thinking so far15:03
bswartzonce I thought through the details and wrote them down, it actually doesn't seem so bad15:03
vponomaryovAbout this BP: Why do we need in manila api called "setup-network"?15:03
vponomaryovIn this case Manila will be mediator, one another failpoint.15:03
*** bill_az_ has joined #openstack-meeting-alt15:04
bswartzvponomaryov: the API name may be poorly chosen15:04
bswartzI strongly suggest that we change it, but I didn't have any better ideas when I was writing15:04
vponomaryovquestion about mechanism, not name15:04
bswartzwell manila must be involved in the mechanism, since the backend drivers in manila will be doing most of the work15:05
bswartzthis is all about configuring the backends storage to join an existing tenant network15:05
bswartzthere will be some code shared between drivers -- most likely in the form of utility functions15:06
caitlin56Question: in neutron terms, is this an additional tenant network, or just adding manila attributes to a tenant network?15:06
bswartzall of the interactions w/ neutron are likely to be common, except that different backends will require fewer or more IP addresses15:06
vbellurwhat would be the workflow here? create network -> create share & then attach share?15:07
bswartzcaitlin56: in neutron terms, we're connecting new resources into an existing network15:07
bswartzthose resources will be virtual with possibly a physical component as well (depending on the backend)15:08
shamailCan you elaborate on "virtual NICs" concept inside Manila?  Is this referring to IP interfaces on the storage provider or is this layer residing in some external translation layer (L2/L3 mapping via neutron)?15:08
*** rakhmerov has joined #openstack-meeting-alt15:08
bswartzshamail: this is referring to the IP interfaces on the storage15:08
shamailbswartz: thanks.15:09
bswartzshamail: In NetApp terms, it would be called a LIF (or a VIF on legacy systems)15:09
shamailYep. :)15:09
caitlin56bswartz: and neutron probably thinks that the storage server has a virtual switch, right?15:09
bswartzIn Linux terms, it would be a tap interface15:09
*** n36107 has joined #openstack-meeting-alt15:09
*** amartellone has joined #openstack-meeting-alt15:10
bswartzcaitlin56: the storage server just needs a VLAN trunk -- or its equivalent in SDN terms15:10
*** rushiagr has quit IRC15:10
*** n36107 is now known as alexpecoraro15:11
shamailThe inclusion of 'trunking' threw me off, but that makes sense... Each LIF/TAP/etc would include a VLAN ID and the switch port is defined as a trunk passing all VLAN IDs.15:11
caitlin56yes, and the other end of a vlan trunk is technically a switch.15:11
bswartzcorrect -- but most storage servers don't use the term "switch" for their internal networking15:11
*** betsy has joined #openstack-meeting-alt15:12
caitlin56and to be real technical it is an IEEE 802.1 "Bridge", which everyone calls a switch.15:12
*** rakhmerov has quit IRC15:12
bswartzcaitlin56: showoff!15:12
shamailDoes this model still leave the door open on all three plumbing options (e.g. native  OVS support, VLAN support, and Gateway support)?  Initially it seems like it does, but does anyone have a different view?15:12
bswartzshamail: I'm inclined to deprioritize the methods that aren't native15:13
*** rushiagr has joined #openstack-meeting-alt15:13
caitlin56I agree. for network plumbing stick with the stuff that Neutron supports.15:14
bswartzi.e. anything that doesn't result in full 2-way network connectivity between the storage and the tenant network is likely to be limitted and less interesting15:14
caitlin56The real question is are we also going to define a non-Neutron solution.15:14
shamailbswartz: agreed15:14
bswartzI'd like to leave the door open for gateway-based approaches in the future, but I think that it's better to get the main use case nailed rather than distract ourselves with lots of use cases15:14
caitlin56+115:15
rushiagrbswartz: +115:15
gregsfortytwoI'm really new in here (just started reading docs two days ago), but I have to interject that any non-NFS/CIFS solution is probably going to have issues if every VM using it needs to have good native access :)15:15
KenDare we planning on using the VLAN ID as a discriminator 'inside' the storage system?15:15
bswartzgregsfortytwo: welcome!15:15
bswartzgregsfortytwo: I'm not sure I understand your concern though15:15
KenD"tenant-discriminator"15:16
caitlin56gregsfortytwo: that is the advantage of the VLAN/VXLAN approach.15:16
bswartzKenD: yeah the idea is that if tenant A is on VLAN 17 and tenant B is on VLAN 49, then the storage system needs to present network interfaces on each of those VLANs so that the tenants cannot access eachother's data15:17
caitlin56VLANs are much easier to audit than NFS export controls.15:17
gregsfortytwowell, I'm thinking about Ceph in particular since that's what I work on, but this would apply to Gluster or whatever as well — if the VM needs to have good support for the shared FS that will limit the OS you can use, or add a lot of necessary extra tooling to do stuff like install FUSE libraries15:17
bswartzthe concern goes deeper than auditting though15:17
caitlin56And don't forget that we are proposing that each tenant be allowed to create multiple security domains.15:18
gregsfortytwoin terms of networking in particular, if every VM needs to have direct IP address to all the storage nodes that's going to be a lot more work for Neutron15:18
bswartzif a tenant has Active Directory setup for their CIFS, or if they have LDAP/Kerberos setup for their NFS, then the storage server needs to coordinate with the various domain controllers for security15:18

*** vkmc has joined #openstack-meeting-alt15:18
caitlin56gregsfortytwo: if you are a multitenant environment, why wouldn't you already have tenant tagging?15:18
gregsfortytwobut I don't want to drop in and derail my first meeting, just wanted to note it :)15:19
caitlin56Just for reference, this is easy on the client side -- the real work is on the server side.15:19
bswartzgregsfortytwo: I'm thinking that "More work" for neutron is just adding a few extra IPs -- once the backend is joined to the right VLAN its not any more work on an ongoing basis15:19
gregsfortytwok15:19
gregsfortytwolike I said, just getting into all this15:20
bswartzanyways, I appreciate feedback on the BP15:20
KenDI am not sure that it would be any more work for neutron, there will already be tenant IDs set up15:20
bswartzI expect we will continue discussing this design through the conference15:20
*** amartellone has quit IRC15:21
caitlin56The only way this is more work for Neutron is if the tenants want multiple security domains specificaly for NAS.15:21
bswartzgregsfortytwo: I'd like to know what specific requirements ceph might have because we intend to accomodate alternative protocols, and I just don't know enough of the details right now15:21
vbellurwould this mean that we modify the create_share API to pass the network identity?15:21
caitlin56Which could happen, but neutron is there to serve tenants (just like Manila)15:21
gregsfortytwobswartz: would it be better to discuss over in #openstack-manila later today instead of right now?15:22
bswartzvbellur: yes I mentioned that in the BP I think15:22
bswartzgregsfortytwo: yes I'll grab you offline15:22
gregsfortytwocool15:22
vbellurbswartz: ah ok15:23
bswartzokay in the interest of time, next topic15:23
bswartz#topic Other BPs15:23
*** jcoufal has quit IRC15:23
*** openstack changes topic to "Other BPs (Meeting topic: manila)"15:23
bswartzso I've seen a bunch of new BPs getting filed, and this is great!15:23
*** rraja has joined #openstack-meeting-alt15:24
shamailI had a question regarding Multi-backed support.  Did Manila keep the filter scheduler functionality that was introduced in Cinder?15:24
bswartzI'm glad to see the interest in the project and I hope we can get several backends included by the end of Icehouse15:24
shamailDoh, sorry. :)15:24
*** caitlin56 has quit IRC15:24
*** caitlin56 has joined #openstack-meeting-alt15:24
bswartzshamail: yes we kept the scheduler15:24
caitlin56It isn't the greatest method of aqdding servers, but we should follow what Cinder has.15:25
shamailbswartz: Thanks, sorry for the deviation.15:25
bswartzdoes anyone want to discuss a particular BP right now?15:25
bswartzor is everything just a placeholder with details to come later?15:25
* rushiagr makes a mental note to test manila filter scheduler in the coming week15:25
vbellurbswartz: most BPs seem to be placeholders atm15:26
bswartzcaitlin56: I actually think that cinder's method of supporting multiple backends is superior to what neutron offers15:26
bswartzcaitlin56: do you have a better idea?15:26
shamailWe are still working internally on our design plan... But here is a place-holder BP for the driver.15:26
bswartznote: I'm aware of some funkiness with how the scheduler actually works in practice, but those are implementation issues15:27
shamail#link https://blueprints.launchpad.net/manila/+spec/emc-driver15:27
bswartzthe design of the scheduler is pretty solid IMO15:27
shamailbswartz: +115:27
bswartzshamail: I updated your BP, targetted to icehouse15:28
bswartz#topic Summit15:28
*** openstack changes topic to "Summit (Meeting topic: manila)"15:28
shamailbswartz: thanks.15:28
bswartzokay so the Hong Kong summit is just 2.5 weeks away (!!!)15:29
shamaildrinks on bswartz!15:29
shamail:)15:29
bswartzlol15:29
KenDDo we have a finalized schedule for manila meetings? or an agenda?15:29
vbellurshamail: +115:29
bswartzI want to have some meetings in Hong Kong for those who are able to travel15:29
KenDshamail +115:30
bswartzmy default plan is 1 or 2 unconference sessions15:30
bswartzrigth now we're working on actually renting a room so we have guaranteed space15:30
caitlin56bswartz: is it fair to say that the agenda for Hong Kong is focused on solidifying manila as a project, rather than on working on manila itself?15:30
bswartzthe main downside to unconference sessions is that they're limitted and we have to schedule them last minute15:31
bswartzif we can get a room, I'll schedule something next week and announce it here in this meeting15:31
bswartzotherwise we have to wait and see what we can get15:31
vbellurok15:32
KenDshould we formalize the session? or are we expecting low attendance in HK?15:32
bswartzmy goal will be to minimize overlap with cinder sessions, and to minimize overlap with neutron/nova sessions that might be of interest to this group15:32
* caitlin56 will be there15:32
vbellurmaybe have a date so that we can plan our schedules around that?15:32
bswartzKenD: we can't formalize it because we're not officially a project yet >_<15:32
shamailbswartz: Appreciate that.15:32
caitlin56+1 to waiting until after Cinder schedule is set to do Manila schedule.15:32
bswartzregarding that, there were TC elections this week, so our request for incubation was not considered15:33
bswartzI expect our request to be considered on tuesday, and I see no reason that it won't be granted15:33
bswartzso hopefully we will be incubated the time of the conf15:33
shamailbswartz: new here, does that mean that we won't get a chance for incubation or did the decision just get deferred a week or two?15:34
caitlin56bswartz: when would it be considered? I'm trying to decide when to press the execs here to let me submit a blueprint for a Nexenta Manila driver.15:34
bswartzregarding the agenda for our meetings, mostly I just want everyone to meet face to face since we'll likely be working together over the next 6 months15:34
shamailbswartz: nevermind, you answered the question already.15:34
bswartzI will prepare some background material we can present and discuss for anyone who hasn't been following us for the last month or 215:35
bswartzbut I don't expect to do any serious arguing and decision making in HK, since we're still quite new15:35
glenngbswartz: That will help.15:35
caitlin56bswartz: I think that's the right set of objectives for now.15:36
vbellurbswartz: sounds like a plan.15:36
bswartzso next week I'll announce a meeting time/place if we're able to get a room15:36
shamailbswartz: thanks.15:36
bswartzotherwise we'll just use the whiteboards outside the unconference rooms15:37
bswartzand I'll try to send out an email after I grab a slot15:37
bswartzI have many of your email addresses already15:37
bswartzi'll ping people who's addr I don't have15:37

bswartzokay so are there any other topics?15:38
vbellurany plans to improve our api documentation?15:38
bswartzwant to continue the discussion about the networking stuff?15:38
bswartzvbellur: we plan to improve the docs, yes!15:39
bswartzvbellur: unfortunately I don't have a timeline15:39
caitlin56On doc, I'd suggest that we focus on *vendors* as much as users. Knowing how to plug in your NAS server is just as important as knowing how to use it.15:39
caitlin56And probably more complex that how a user accesses it.15:39
bswartzif anyone wants to help out there I'd appreciate it15:39
bswartzyes writing docs that make it easy for vendors to write backends is important15:39
rushiagrlets have it as a blueprint if it is not already there?15:40
vbellurbswartz: yeah, maybe we should set a timeline for getting the apis along the lines of http://docs.openstack.org/api/openstack-block-storage/2.0/content/15:40
shamailbswartz: I plan to review the code and make an architectural diagram.  I'd love your feedback and hopefully we could post it eventually.15:40
* caitlin56 volunteers to help on vendor doc.15:40
vbellurrushiagr: sounds like a good idea15:40
bswartzvbellur: oh those are more boilerplate15:40
rushiagrshamail: awesome. I'll like to take a look too!15:40
bswartzvbellur: we do need those, but not having those doesn't block anybody from making progress during Icehouse I don't beleive15:41
rushiagr^ about arch diagram15:41
shamailYeah, I'll try to share it with everyone via the Manila room.15:41
vbelluryeah, i agree but we can have a WIP guide15:41
bswartzshamail: excellent15:41
bswartzcaitlin56: want to post a BP covering what you plan to write?15:42
rushiagrI'd definitely help with the docs, but I generally pitch in when I see incompleteness in content, and not when the content is not there at all :P15:42
bswartzI think a wiki page would be a good format for a "howto write a manila backend"15:43
vbellurbswartz: agree15:43
shamailDo we want to focus on writing any new schedulers or improving the current implementation in the ice house time-frame?15:43
bswartzshamail: we've inheritted a lot of stuff from cinder already, and I plan to keep stealing their good ideas15:44
bswartzI don't want to spend much effort on working on those overlapping areas though when we still have some basic features unimplemented15:44
bswartzwe need to get the multi-tenant networking working, that's top priority15:45
caitlin56bswartz: need exec approval first. Right now I'm still "investigating" manila.15:45
*** basha has joined #openstack-meeting-alt15:45
caitlin56But doc, that I can do on my own.15:45
bswartzsecond priority is getting backends written and validated so we know that our design is not boneheaded15:45
bswartzin 6 months I hope we will be able to go to the next summit and discuss new feature ideas15:46
*** rushiagr has quit IRC15:46
bswartzI think we have plenty to do for the next 6 months15:46
bswartzthat said, if someone wants to bite off a project, feel free to submit a BP and work on it and we'll try to get it included during Icehouse15:46
bswartzokay last call for topics15:47
bswartzwe have a bit of time left15:47
bswartzalright thanks everyone15:48
vbellurthanks all15:48
shamailIs there a link to a template backed driver?15:48
bswartzshamail: there is a generic driver in tree right now15:48
shamailSee y'all later!15:48
*** rushiagr has joined #openstack-meeting-alt15:48
bswartzhowever it's single tenant15:48
shamailWe'll go ahead and take a look at it.  Thanks again.15:49
bswartzonce we have multi-tenant networking there will be 2 generic drivers, and the multitenant generic driver will be a better template15:49
bswartzokay thanks all for this week15:49

SergeyLukjanovfolks, feel free to post updates here18:12
SergeyLukjanovthe main update from me - 0.3 release :)18:12
ErikBOn the HWX side, we've been busy creating a patch for Quantum/Neutron w.out public ips necessary18:12
*** NikitaKonovalov has joined #openstack-meeting-alt18:13
aignatovthis week I mostly concentrated on preparing docs, also composed a demo about edp18:13
ErikBIn addition, we're in the merge process of adding support for various HDP services (Oozie, Hive, etc.) This will eventually be backported to 0.318:13
ruheErikB, do you have any ETA in mind for Quantum/Neutron without public ips?18:13
aignatovlet me post a link to the my edp demo18:13
aignatov#link https://docs.google.com/file/d/0B_AT3b7ftRKeNm9hSlhaTm1CYkE/edit?usp=sharing18:14
SergeyLukjanovok, any more updates?18:15
*** nadya has quit IRC18:15
ErikBruhe, we *should* be starting merge to master this week if all goes well, pending review, perhaps all wrapped up next week.18:15
ruheSergeyLukjanov, when do you plan to release 0.3.1?18:17
SergeyLukjanovruhe, I'm thinking about doing it in 2-3 weeks18:17
SergeyLukjanovto have a release for the OS summit in HK18:17
SergeyLukjanovit'll be good to have at least transient clusters fully op. in it and EDP support in HDP plugin18:18
ruheok18:18
aignatovHive support as well I think18:19
aignatovin edp18:19
SergeyLukjanovyeah, good point, it'll be good to add it too18:19
SergeyLukjanovsome UI and docs polish maybe too18:19

ruhetmckay, you should receive vote ticket in your registered email18:22
tmckayokay :)18:22
aignatovthe subject is : "Poll: Savanna Topics for OpenStack Havana Design Summit"18:22
SergeyLukjanovall savanna contributors should receive free ATC pass to Hong Kong summit18:23
jmaronnadya:  John did most of the Hive integration, but one of the main concerns/issues he related was managing the service/component dependencies in a "user friendly" fashion (i.e. how does a user recognize that certain services are required for Hive deployment if they are selecting individual components?).18:23
SergeyLukjanovok, let's move on18:23
SergeyLukjanov#topic Roadmap cleanup / update18:24
*** openstack changes topic to "Roadmap cleanup / update (Meeting topic: savanna)"18:24

ruhes/this/with18:24
SergeyLukjanovnothing to update in roadmap from mi side18:24
dmitrymeruhe, if I understand jmaron correctly, it is not about implementation, it is about UI18:25
dmitrymei.e. how we will present to the user, 'please turn on this service, if you want that one to work'18:25

dmitrymeas far as I recall jspiedel already wrote a letter about it in openstack-dev18:26
dmitrymewe just didn't had time to think about it18:26
jmaronruhe:  true.  I think there is already an architecture discussion proposed, so it could be discussed there18:27
jmarondmitryme:  true, he did18:27
SergeyLukjanovanything else to discuss today?18:29
jmaronservice dependencies can probably be discussed in proposed Heat session or New Architecture session18:29
SergeyLukjanovI'll merge sessions to fit 4 time slots18:30
SergeyLukjanovI hope that the most parts of proposals will be landed to the summit sessions18:30
nadyawho is going to HK? :)18:31
ruhebtw, i've read blogposts on Hortonworks site. reference Hadoop2 architecture with namenode HA requires ZooKeeper18:31
ruhethat's a very tricky dependency :)18:31
*** kevinconway has joined #openstack-meeting-alt18:32

SergeyLukjanovruhe, yeah, especially isn virtual environment18:32
* aignatov has moved 0.3 docs bp to implemented18:34
ruhei know it might be too early to discuss, but i'd like to hear, what you guys would like to implement during IceHouse?18:34
SergeyLukjanovaignatov, thx18:34
ruhethat's a question to everyone18:35
SergeyLukjanovmattf, what's about fedora?18:35
SergeyLukjanovruhe, lowercase 'h' in Icehouse18:35
*** slagle has quit IRC18:36
tmckaypersonally, I'd like to keep expanding edp -- different data/job sources (external swift, hdfs, gluster, others?)18:36
aignatovHadoop 2.0 support and +1 to tmckay18:36
crobertsrhI think that some sort of monitoring support is in order in the UI.18:36
akuznetsov +1 to tmckay18:36
tmckaywe also talked at one point about hooking savanna into build servers somehow...18:37
nadya+1 to Trevor + Sqoop18:37
tmckayand, I would *love* to see better error reporting in horizon.  "Status: Error" is not helpful.18:37
tmckayoh, and "relaunch" of a job execution18:38
aignatovin edp I'd like to expand job configurations and to support not only Hive, Pig and Jar18:38
SergeyLukjanovI hope that we'll be able to migrate to some common rest api framework with better exceptions handling18:38
tmckayI think it would be useful.18:38
crobertsrhtmckay:  I just submitted a bug for relaunch of job-execution :)18:38
tmckay+118:38
dmitryme+1 to tmckay: be more nice with a user18:38
tmckaywe also talked about allowing user uploaded Oozie workflows.18:39
SergeyLukjanovfor me, the main goal for the next milestone is to integrate with other OS projects and graduate from the incubation18:39
jmaronenhanced UI experience (service/component dependencies, template editing) would be nice18:39
dmitrymealso I'd like to see Savanna more scalable and resilient18:39
NikitaKonovalov+1 to tmacky and jmaron, there are a lot of areas to improve UI18:39
jmarondmitryme:  +1, especially around large clusters18:39
tmckaySergeyLukjanov, +1, there was a lot of talk at the incubation meetings of Savanna integrating with Heat, etc.  Maybe if those projects don't have what Savanna needs, we can jump on and help them get there :)18:40
aignatovSergeyLukyanov, yes, that's the highest priority for all of Savanna contributos18:40

markwash#topic project status meeting update20:04
*** openstack changes topic to "project status meeting update (Meeting topic: glance)"20:04
markwashJust taking the opportunity to pass info down from the weekly openstack project meeting20:04
markwashthis week was fairly uneventful for glance, but as you all know, rc2's and rc3's are out for all the projects20:05
markwashsince glance seems pretty stable post rc2, we're full steam ahead on new code20:05
iccha_woohoo!20:05
markwash(because we have no reason to believe we need to worry about backporting bug fixes needing to be especially easy)20:05
markwashthere is also some install documentation in a wiki that glance folks might want to check out and see if they can contribute to20:06
markwash#link https://wiki.openstack.org/wiki/HavanaDocTesting20:06
markwashthanks again to everyone for their efforts with rc220:06

markwashI think we could still fill out some more info there for "known issues" i.e. bugs that we're carrying over that are significant20:08
markwashand also possibly upgrade notes20:08
*** melnikov has joined #openstack-meeting-alt20:09

*** openstack changes topic to "releasing glanceclient (Meeting topic: glance)"20:17
* markwash searches for a good link20:18
iccha_we seem to have major functionaility for glanceclient to talk to glance v2 api in20:18
markwashcouple of significant bug fixes have gone in here https://review.openstack.org/#/q/status:merged+project:openstack/python-glanceclient,n,z20:18
markwasherm20:18
markwash#link https://review.openstack.org/#/q/status:merged+project:openstack/python-glanceclient,n,z20:18
markwashI'd like to do a minor release very soon to grab those fixes20:19
markwashin particular I'm worried that the ones russ did are probably really important otherwise why would he bother?20:19
iccha_what version is gc currently on?20:19
markwash0.11.020:20
markwashas for a major release20:20
markwashthere is something I've been stewing on for a while in private20:20
markwashI really don't care for the fact that we use our own SSL stuff20:20
markwashand I think we should switch to using requests20:20
iccha_could you elaborate markwash ?20:21
buzztrollon first read that makes a lot of sense to me20:21
markwashbcwaldon was churning on both those items, but couldn't come up with a really satisfactory answer, because our custom SSL stuff is there to optionally disable ssl compression20:21
buzztrolli havent thought about it before20:21
markwashthe idea is that disabling compression makes uploads of already compressed images much faster20:21
markwashwhich makes sense, but python just doesn't support it very well yet in terms of common libraries20:22
markwashanyway, I think we should revisit the major release in a week or two20:22
markwashany objections to a minor release in the next few days?20:22
buzztrollin my opinion the transfering of images in terms of efficiency in glance is quite imperfect right now anyway20:23
markwashbuzztroll: yeah true20:23
buzztrollso leaning towards more supportable code and away from efficiency seems ok to me20:23
esheffield+!20:23
markwashI need to pressure bcwaldon to submit the review if he ahsn't already20:23
esheffielder, +1 :-)20:23
buzztrollbecause it is already a neglected category, why have tiny bandaides?20:23
markwashyeah20:23
buzztrolljust my 2 cents there20:24
markwashk20:24
buzztrollno objection at all to a minor release20:24

markwashsome nice folks suggested bugs for us to consider in the meeting20:25
*** ashwini has joined #openstack-meeting-alt20:25
markwashfirst one20:25
markwash#link https://bugs.launchpad.net/glance/+bug/117697820:25
markwashthe issue is about how our deleted indexes make it so you cannot reuse an image id20:26
markwashfor most users this has no significance, because they cannot specify the image id on create anyway (by policy)20:26
buzztrollugh20:26
markwashI think folks sensibly think its pretty silly to reuse a uuid20:26
ameade_yeah20:26
buzztrolli think i am on record as not liking the idea of reusing IDs20:26
buzztrollyeah20:27
markwashhowever, I think there are some rare operational situations where it makes sense20:27
ameade_seems like glance-replicator needs it or something?20:27
markwashand i guess we'd just be saving folks the trouble of doing the mysql themselves20:27
*** demorris has joined #openstack-meeting-alt20:27
buzztrolli fear it would move the problem around20:27
*** rakhmerov has joined #openstack-meeting-alt20:27
markwashalso I think fixing the underlying db issue would help with some performance areas as well20:27
*** jmontemayor has quit IRC20:28
markwashI'm not sure we will have a fast answer in this meeting20:28
zhiyanmarkwash: do you think it is make sense if we support recover a pending-delete status image back to active ?20:28
buzztrollmarkwash: probably not20:28
buzztrollmarkwash: i am trying not to run off on tangents and derails the meeting with this topic20:28
* buzztroll behaves20:28
markwashzhiyan: that makes sense, but I'm not sure its necessarily a substitute for what folks are trying to do20:28
markwashanyway, i'd love to see folks post their thoughts on the bug if they haven't already20:29
buzztrollmarkwash: cool will do20:29
markwashI suspect fixing the db would just pick a winner in this debate anyway20:29
markwashanyway20:29
markwashnext one!20:29
markwash#link https://bugs.launchpad.net/glance/+bug/119734420:29
nikhilzhiyan: that would mean adding a re-use option in the CRUD methodology20:29
ameade_just marked it as invalid :P20:30
iccha_would multiple locations help?20:30
markwashbasic issue: v2 doesn't show deleted images20:30

iccha_glance verifying tenants with keystone has been a topic repeatedly brought up20:32
markwashbasic issue: if I delete a keystone project, all the images for that project still exist20:33
markwashiccha_: I think this bug is related but a little bit different20:33
iccha_yeah i was speaking off a similar conversation20:33
ameade_i think if we do need this addressed it should probably be handled outside of glance?20:33
ameade_that's my gut feeling20:33
iccha_and our stance has always been that we want separation of concern20:33
markwashyeah, I think that is a fair point20:34
nikhilwe need superglance20:34
markwashin any case its certainly not something we can just solve by ourselves20:34
markwashwe need either a separate project taht does this cleanup20:34
markwashor we need some standard way of consuming openstack notifications to delete things20:34
markwasheither approach would work20:34
nikhilthat makes sense20:34
zhiyanmarkwash: i'm thinking again glance-worker ...20:35
markwashso I think we really want some TC guidance on this. . I'd really like the TC to adopt/suggest a path forward on this across the board20:35
nikhilhow can we ensure glance as a stand alone service if it's married to openstack then or that is not one of the goals?20:35
markwashnikhil: I think we're married to keystone at least20:35
markwashprobably nova too20:35
markwash(must be Utah)20:35

markwashI saw one review I just wanted to bring up here briefly20:39
markwashhttps://review.openstack.org/#/c/46715/20:39
markwashsomeone is helpfully contributing unit test coverage20:39
*** demorris has quit IRC20:39
markwashseveral folks have been, actually, adding in use of mock20:39
markwashwhich IMO is much nicer than mox20:39
ameade_i would prefer the context manager over decorator20:39
ameade_for mock.patch20:39
ameade_but i don't have a strong opinion20:40
nikhil+1 ameade_20:40
iccha_i think there was universal propagation for mock vs mox20:40
buzztrolli thought we decided a bit ago that everything would be mock instead of mox from now on?20:40
markwashameade_: thanks, I'm just not that familiar with it so your opinion is very helpful for context!20:40
nikhilthough nesting is trick with context manager20:40
markwashbuzztroll: yes. I think we're all good with mock20:40
markwashmy question is just mock.patch20:40
markwashmostly the thing I don't like is that the order of the decorators is the reverse of the order of the extra arguments passed to the test function20:41
ameade_nikhil: true story....i think we should just be consistent with one way20:41
markwashdue to how decorators work20:41
ameade_yeah decorators are wack20:41
vkolosovGuys, it was my commit. :)20:41
markwashokay well I'm not super worried about this patch, I dont think it will kill us even if we don't love mock.patch :-)20:41
markwashvkolosov: hi!20:41
markwashvkolosov: any thoughts then based on this conversation? keep in mind I'm thrilled for the extra test coverage20:42
vkolosovI used decorators to avoid multiple nesting20:42
vkolosovThat's all. :)20:42
*** rudrarugge has joined #openstack-meeting-alt20:42
markwashhmm, yeah all that tabbing could be worse20:42
nikhilit's hard to read/review though with decorators20:43
vkolosovI noticed that many unittests actually are not UNIT test20:43
markwashvkolosov: yeah :-( they sure aren't20:43
ameade_haha no doubt20:43
vkolosovSo I tried to make them more like "unit"20:43
nikhillearn't hard way that tabbing (or not tabbing) could result into a useless tests20:43
vkolosovAnd used a lot of mock decorators20:43
markwashvkolosov: we're all on the same page there, but its been slow going, trying to keep sufficient coverage20:43
ameade_nikhil, markwash: if we have to nest too deep it's a code smell, i like everything being in the test function...but i really dont wanna dwell on this20:44
markwashwell, it may be the case that mock.patch is the least problematic way of doing this20:44
nikhilvkolosov: :) good point (agree about unit tests)20:44
nikhilameade_: haha true! :)20:44
markwashokay, well folks chime in on the review, I'm removing my -120:44

buzztrollit could be yeah20:54
buzztrollthere are some nuances20:54
nikhil+1 from me20:55
buzztrolllike backward compat20:55

buzztrolli used it in nova20:55

buzztrollif i can find it20:55
