15:00:46 <manjeets> hi
15:02:38 * mlavalle waiting a little for others to join
15:03:59 <mlavalle> ok, let's get moving
15:04:11 <mlavalle> #topic Announcements
15:04:43 <mlavalle> Rocky-3 is a little more that a week away
15:04:54 <mlavalle> July 23 - 27
15:05:25 <mlavalle> thanks to manjeets or keeping an eye on the targeted bluperints and community goals ;-)
15:05:53 <manjeets> :)
15:06:28 <mlavalle> also to haleyb who took the time yesterday to go through my big multiple port bindings patch. I'll address your comments today ;-)
15:07:05 <mlavalle> Please also keep in mind that next week we are going to release neutron-lib again
15:07:09 <haleyb> mlavalle: sorry, totally forgot
15:08:07 <manjeets> should  this https://review.openstack.org/#/c/577245/ wait then for 1.18 ?
15:08:30 <mlavalle> boden sent a message yesterday. If you have a patch that you want to be included in next week's release, please leave a comment in it with "rocky-candidate"
15:09:16 <mlavalle> we are especially interested to get this patch in that release: https://review.openstack.org/#/c/319328/
15:10:05 <mlavalle> also this one: https://review.openstack.org/#/c/580786
15:10:32 <mlavalle> although this one will be affected by haleyb's comments to the port binding patch, so expect an update for it
15:11:04 <haleyb> mlavalle: were you going to fix the "returns" in that second one ?
15:11:21 <haleyb> i know it was a nit...
15:11:47 <haleyb> the first one i hadn't taken a look at... quite large
15:11:57 <haleyb> oh, and old
15:13:34 <mlavalle> haleyb: yes, in the get_port_binding_by_status_and_host I am going to let the caller request an exception to be raised if the expected binding (active or inactive) is not found
15:14:04 <mlavalle> I'll explain further the reasoning behind that in my response to youir comments
15:14:52 <haleyb> mlavalle: ok, i'll wait for the comments, i didn't remember callers raising if not found but you would know best
15:15:42 <haleyb> mlavalle: for the lib change were you going to address boden's nit?  otherwise it's good to go
15:16:12 <haleyb> missing ":returns: ..." in docstring
15:16:19 <mlavalle> haleyb: yes and also, if we adopt the solution I propose to your comments, the code will change a bit
15:17:56 <mlavalle> before the change, I'll ping you in channnel to discuss
15:18:11 <haleyb> ack
15:18:31 <mlavalle> This coming Tuesday 17th is the deadline to propose talks for Berlin
15:18:49 <mlavalle> any other announcements from the team?
15:20:43 <mlavalle> ok
15:20:48 <mlavalle> #topic Bugs
15:22:00 <mlavalle> First https://bugs.launchpad.net/neutron/+bug/1757482
15:22:00 <openstack> Launchpad bug 1757482 in neutron "IP address for a router interface allowed outside the allocation range of subnet" [High,In progress] - Assigned to Miguel Lavalle (minsel)
15:22:39 <mlavalle> hongbin had some comments on the fix last week: https://review.openstack.org/#/c/575444/
15:22:59 <hongbin> o/
15:23:27 <mlavalle> I responded to them but I would like haleyb to take a look. If you are still ok with the patchj, pleaase merge it
15:23:37 <haleyb> mlavalle: ack, will look
15:24:01 <hongbin> mlavalle: your respond is fair enough, i am fine with it
15:24:17 <mlavalle> hongbin: cool, thanks ;-)
15:24:57 <mlavalle> Next bug is https://bugs.launchpad.net/neutron/+bug/1711463
15:24:57 <openstack> Launchpad bug 1711463 in neutron "TestNetworkBasicOps.test_network_basic_ops failed with "Timed out waiting for 172.24.5.8 to become reachable"" [High,Confirmed] - Assigned to Miguel Lavalle (minsel)
15:25:30 <mlavalle> For this one, I spent time preparing for this meeting searching Kibana for hits
15:26:14 <mlavalle> the bug, as filed by Ihar and later also updated by boden, referred to failures with greandes jobs
15:27:25 <mlavalle> I created searches (which I added in #3) for neutron-grenade-dvr-multinode, neutron-grenade-multinode and neutron-grenade
15:28:36 <mlavalle> I don't get any hist over the past 7 days
15:29:16 <mlavalle> If I change the search for any build in openstack/neutron, I get 28 hits over the past 7 days
15:29:48 <mlavalle> 24 for of those, though, are with neutron-tempest-dvr-ha-multinode-full, so it is probably expected
15:30:10 <mlavalle> There are 4 with build legacy-grenade-dsvm-neutron-linuxbridge-multinode
15:30:25 <mlavalle> do you guys know where are we running that job?
15:30:38 <mlavalle> it's not in master check
15:32:25 <haleyb> i don't know then, strange
15:32:47 <manjeets> if  recall correctly this used to be there 2 cycles back, since then, zuul v3 and other changes may have lost this job
15:33:57 <manjeets> or job name may have changed
15:33:58 <manjeets> http://codesearch.openstack.org/?q=legacy-grenade-dsvm-neutron-linuxbridge-multinode&i=nope&files=&repos=
15:34:17 <mlavalle> shows up in kibana over the past 7 days
15:35:34 <mlavalle> I'll dig in
15:35:38 <haleyb> it's not in any zuul listing on changes
15:35:56 <manjeets> does kibana records experimental jobs ?
15:36:06 <mlavalle> we can also discuss in the CI meeting next week. maybe slawek has seen it
15:37:07 <mlavalle> haleyb: would it be a waste of time if we try to see why the failures in the neutron-grenade-dvr-multinode job?
15:37:52 <haleyb> mlavalle: yes, that linuxbridge job is in experimental, which only runs on-demand
15:38:16 <mlavalle> ok
15:38:38 <haleyb> and it's been run a few times this past week
15:39:02 * njohnston checks graphite...
15:39:28 * haleyb even remembers njohnston running experimental :-p
15:40:12 <manjeets> https://review.openstack.org/#/c/578886/ I did check experimental on this
15:40:47 <mlavalle> ahh yeah
15:40:52 <haleyb> mlavalle: regarding neutron-grenade-dvr-multinode - is that failing on master?
15:41:12 <mlavalle> haleyb: no, I didn't get any hits over the past 7 days
15:41:36 <mlavalle> not for the bug we are talking about
15:42:32 <mlavalle> so I won't worry about the hits in the linuxbridge job
15:42:55 <mlavalle> The next bug that I have is https://bugs.launchpad.net/neutron/+bug/1766701
15:42:55 <openstack> Launchpad bug 1766701 in neutron "Trunk Tests are failing often in dvr-multinode scenario job" [High,Confirmed] - Assigned to Miguel Lavalle (minsel)
15:43:23 <mlavalle> I haven't made much progress on this one
15:43:40 <mlavalle> But the next step is to do the same that I am doing with the previous one in Kibana
15:44:06 <mlavalle> I'll update the bug and report next week in this meeting
15:44:25 <mlavalle> Any other bugs we should discuss today?
15:44:45 <haleyb> there might have been one new one
15:44:56 <haleyb> https://bugs.launchpad.net/neutron/+bug/1780094
15:44:56 <openstack> Launchpad bug 1780094 in neutron "The transition of a router from distributed to centralized may mistakenly get HA enabled" [Medium,In progress] - Assigned to Kailun Qin (kailun.qin)
15:45:08 <haleyb> currently being debugged
15:45:43 <mlavalle> right, I forgot. swami mentioned it last week
15:46:00 <mlavalle> should we raise its priority so it is visible?
15:46:19 <mlavalle> in the searches we have in the meeting etherpad
15:46:25 <haleyb> it's being worked on, i'm watching it
15:46:33 <mlavalle> ah ok, perfect
15:46:45 <mlavalle> ok, let's move on
15:46:57 <mlavalle> #topic Port Forwarding
15:47:09 <mlavalle> I have been reviewing the series
15:47:26 <mlavalle> https://review.openstack.org/#/q/topic:bp/port_forwarding+(status:open+OR+status:merged)
15:47:43 <manjeets> mlavalle, first patch adding db and ovo now looks good to me !
15:47:44 <mlavalle> manjeets and haleyb have also take a look at some of the patches
15:47:46 <mlavalle> thanks
15:48:22 <mlavalle> This past Tuesday I spent time with this one https://review.openstack.org/#/c/574673
15:48:52 <mlavalle> and was having a hard time understanding why we need locks to handle "race conditions"
15:49:33 <mlavalle> in principle, the db layer transactions must handle most of that
15:49:39 <mlavalle> what do you guys think?
15:49:58 <mlavalle> am I being too simplistic?
15:50:40 <davidsha> What patch introduced the locks to prevent race conditions? Does it reference a bug?
15:50:52 <davidsha> Hello btw :)
15:50:54 <haleyb> mlavalle: and i'm sure you saw the response when asked about it in PS8
15:51:11 <mlavalle> davidsha: https://review.openstack.org/#/c/574673
15:51:22 <haleyb> i have seen another change recently doing similar things with @runtime.lock...
15:51:49 <mlavalle> haleyb: to tell you the turth, I didn't understand it, so I asked again in PS11, this past Tuesday
15:52:31 <haleyb> oh, the answer was even longer this time, i haven't parsed it all yet
15:53:04 <mlavalle> ok, please let's take a look and try to steer this patch towards a simpler approach
15:53:23 <xbzhang> hi I want to know how we can make 528336 to rocky release?
15:53:27 <mlavalle> I feel relieved that I am not the only one having trouble undertanding the reasoning behind it
15:54:09 <xbzhang> also 472289
15:54:11 <manjeets> patch looks cheesy, but I need to spend more time to understand it as well and need to catch up with zhaobo's replies
15:54:18 <manjeets> mlavalle, ^^
15:54:40 <mlavalle> xbzhang: gives us a moment to finish this topic
15:54:56 <xbzhang> ok
15:55:09 <mlavalle> davidsha: https://review.openstack.org/#/c/574673/
15:55:21 <mlavalle> This is the patch,. Take a look if you have some time
15:55:49 <mlavalle> other than the locks business, the 3 server side patches seem in reasonably good shape to me
15:56:02 <davidsha> mlavalle, Thanks, I'll check it out!
15:56:52 <mlavalle> davidsha: you might find useful looking at the spec: https://specs.openstack.org/openstack/neutron-specs/specs/rocky/port-forwarding.html
15:57:07 <mlavalle> #topic OpenFlow DVR
15:58:03 <mlavalle> xbzhang: https://review.openstack.org/#/c/528336 seems like a fair bet to make it to Rocky
15:58:36 <mlavalle> That is actually a great first step for OpenFlow DVR
15:58:38 <xbzhang> ok thanks
15:58:56 <mlavalle> 472289
15:59:02 <mlavalle> seems more complicated
15:59:15 <mlavalle> but I will add to my pile and see what we can do
15:59:29 <mlavalle> ok, ran out of time
15:59:40 <mlavalle> Thanks for attending
