*** itsuugo has joined #openstack-neutron09:04
ajoramishra, can you send an extra patch to devstack to take away Q_PLUGIN_EXTRA_CONF_PATH and use /etc/neutron as default?09:04
ajolet's see if that works, because otherwise that setting is overriden between pluggins09:04

ramishraajo: Which other plugins are we worried about? We use most both lbaas, vpnaas. fwaas is not there.09:05
ajoramishra, I'm worried that other plugin will come and change that path09:06
ajoit makes no sense to have it mutable09:06
ajoand will only cause harm (as it already did)09:06
ramishraok, should we then revert the lbass patch.09:06
ramishralbaas09:06
*** hoangcx has quit IRC09:06
ramishraI can propose that.09:07
ajoramishra, no, we should set the default in devstack itself, remove the setting09:08
ajoand then we can remove that bit on lbaas and vpnaas if we want09:08
ramishragetting a devstack patch in would take ages;)09:08
ajoramishra, I'm not saying it has to be in series with this, can be just parallel09:08
ajoif you see I moved my vote to +109:09
ramishraok, can we get this patch in now, it's a broken gate for 3 days for us.09:09
ajook, whatever, let me do it myself :P :) but move along with your patches, I don't intend to block you :)09:09
ajoramishra, understood, sorry about that09:09
ajothat's what I intend to avoid with the devstack change09:09
ajoany future havoc09:09
ajobecause of anyone tweaking the flag09:09
*** hoangcx has joined #openstack-neutron09:12
ramishralbaas patch should not have not used it at the first place. We would much happier if we revert that patch though. Our intent is to fix the gate:)09:12
openstackgerritLIU Yulong proposed openstack/neutron-dynamic-routing: Try to get DVR fip bgp next_hop when associating  https://review.openstack.org/37231009:17
ajoramishra, if you revert that, you break other stuff :), if you want do a partial change to include /etc/neutron/ in the path of the files added in the lbaas plugin, and remove the usage of the Q_PLUGIN_EXTRA_CONF_PATH09:22
ajoramishra, https://review.openstack.org/37233709:25
ramishraajo: which other stuff it would break? May be I'm missing something. I can see it fixes 2 bugs, so you've to fix them again, right?09:25

ajosc68cal, also if you could ^09:36
* nmagnezi looks09:36
ajo(sc68cal pinging you because there is a related devstack patch to avoid future havocs)09:37
nmagneziajo, what i don't understand is, should i have used Q_PLUGIN_EXTRA_CONF_PATH in a different way?09:39
ajonmagnezi, the issue is09:39
ajonmagnezi, that if you setup lbaas and vpnaas plugins09:39
ajolbaas sets that var, while vpnaas leaves it empty09:39
ajofinal result09:39
ajovpnaas files end as /etc/neutron/etc/neutron/blahnlah09:39
ajothe logic of Q_PLUGIN_EXTRA_CONF_PATH is broken, _FILES is aditive, while _PATH is not09:40
*** itsuugo has quit IRC09:40
ajoit does not work if you have different sources adding stuff, and expeting Q_PLUGIN_EXTRA_CONF_PATH to be different09:40

nmagneziajo, what if we add the same variables to https://github.com/openstack/neutron-vpnaas/blob/master/devstack/settings ?09:45
ajonmagnezi, what if a third plugin comes and change that var again? :)09:45
ajonmagnezi, that's what ramishra was initially proposing to vpnaas, set the var also to /etc/neutron, and move vpnaas into the other format09:46
ajoThat's also another option,09:46
ajobut I'd prefer to get rid of Q_PLUGIN_EXRA_CONF_PATH alltogether09:46
nmagneziajo, i think yamamoto is working on that09:47
*** itsuugo has quit IRC09:47

*** hoangcx has quit IRC09:48
*** liangbo has joined #openstack-neutron09:48
*** yamamoto has quit IRC09:48
ajonmagnezi, so, we should merge either the ramishra vpnaas patch, or my lbaas patch09:49
ajoto unbreak heat09:49
ajoif the option is going to be deprecated, I'd go with the lbaas one better09:49
nmagneziajo, i agree that one of ^^ is the needed short term solution09:49
nmagneziajo, i tend to lean towards ramishra's patch since we can maintain it. (we can just fix all plugins, it's a very tiny change to each patch)09:50
ajonmagnezi, and then we have to go back and fix all the plugins again when deprecated?09:50
ajo:P09:50
ajoI prefer to do it only once, if possible09:50
ajounless there's a technical reason not to do it09:50
*** donghao has joined #openstack-neutron09:50
nmagneziajo, +1 , but it does not seem like yamamoto's patch is going to be merged soon09:51
ajonmagnezi, but you don't need yamamotos patch for my change, or do we?09:51
nmagneziajo, so but reverting my patch, we just restore the initial problem we had in lbaas (and yes, we unbreak heat)09:51
nmagneziajo, nop09:51
*** tonytan4ever has quit IRC09:52
ajonmagnezi, then let's stop using that _PATH config as vpnaas did, and let's stay out of blame :P09:52
*** edand has joined #openstack-neutron09:52

nmagneziajo,  i don't mind doing that check09:53

ajoI will look at  the neutron cmdline for startup to make sure it's grabbing the right files09:53
nmagneziajo, aye. I'm going AFK for 1h, will also check this and ping you as soon as i return09:54
ajoit's haproxy driver what didn't work without that, right?09:54

ramishraajo: It's little unfortunatee that none of the neutron and other plugin jobs/tests could detect the issue. It would make lot more sense to have some jobs/tests that use these plugins together rather than us debating on small changes/technical debt and holding on a broken gate;) However, I would leave it to neutron teams better judgement:)10:02

jlibosvaihrachys: I still don't get how can it work that you use assert_max_execution_time as a decorator. I'd expect to return some context manager object16:12
ihrachysjlibosva: ? the context manager returns you another callable that is a result of executing the manager on the function passed as an argument16:12
jlibosvaihrachys: I'd expect it to return an object that implements __enter__ and __exit__ interfaces, not a callable16:14
jlibosvaihrachys: I mean, I understand what you're doing but I don't understand why it works :D16:14
ihrachysjlibosva: well I guess __call__ is still there. assert_max_execution_time could as well be a simple function without manager applied16:15
ihrachysjlibosva: I assume that __call__ will call __enter__ and __exit__ in proper time.16:15

*** thorst_ has quit IRC16:18
jlibosvaihrachys: I read that already back and forth to see whether I see something odd there. My point is that you don't return contextmanager but yield of a function that is decorated by contextmanager16:18
*** thorst_ has joined #openstack-neutron16:18
jlibosvaihrachys: "The function being decorated must return a generator-iterator when called. This iterator must yield exactly one value, which will be bound to the targets in the with statement’s as clause, if any."16:19
ihrachysjlibosva: we never use the function there with with, so @contextmanager does not play a role I suspect16:19
*** pbandark has quit IRC16:20
ihrachysjlibosva: you can have a function that can be used as-is, OR as a manager. in our case, we don't use the latter mode.16:20
ihrachysyou just call to the function.16:20
jlibosvaihrachys: yeah, so the object that is returned should work with with, not as a callable. That's what doesn't make sense to me :-/16:20

ihrachysjlibosva: apparently contextmanager returns some callable :)16:20

johnsomarmax Just a friendly reminder that I think you need to wave your wand over this change: https://review.openstack.org/#/c/370456/21:45
armaxjohnsom: I need to check with the TC to see when these changes are open for review21:46
armaxI am not sure now it’s the right time21:46
armaxmestery perhaps would know better, but that’s on my radar21:46
* mestery generally knows very little21:47
Sam-I-Ammestery: good life choices21:47
armaxmestery: you don’t have to say it publicly though21:47
armaxmestery: just pretend you do know a lot21:47
mesteryarmax: Own your incompetency is what I always say21:47
johnsomHmm, ok.  I plan to release Octavia 0.9.0 next week via the new process.  I thought maybe we needed this in place for that to all flow smoothly.21:47
armaxso wise21:47
armaxyou’re right21:47
mesteryarmax: It's years of experience21:48
armax...and ignorance21:48
mesteryThat goes without saying21:48
Sam-I-Amits spelled 'ignerence'21:48
armaxSam-I-Am: sorry, I am not native21:48
mesteryI'll say21:48
Sam-I-Ami was joking. its fun to misspell that word though. :)21:48

kevinbentoncarl_baldwin: i'm having trouble reconciling what you said in the bug report with your comment on the patch22:34
carl_baldwinkevinbenton: looking...22:34
kevinbentoncarl_baldwin: ack22:34
carl_baldwinkevinbenton: Let me look at the log again.22:35
kevinbentoncarl_baldwin: in the bug report you said its the DHCP port update from the agent, right?22:35

carl_baldwinkevinbenton: The first I see of the delete_subnet (req-d0f74aa2-a45a-4fb3-9757-a9f0b06329d9) is at 18:54:33.179. The first I see of the update_port (req-06c10180-b446-4905-b3d5-ae9e27ca8766) is 18:54:32.89722:41
*** mriedem has quit IRC22:41
carl_baldwinkevinbenton: Hold on...22:42
*** mlavalle has quit IRC22:43
carl_baldwinkevinbenton: that made me think the update port was independent of the subnet delete.22:43
*** mmalik4 has joined #openstack-neutron22:44
*** trevormc has quit IRC22:45
carl_baldwinkevinbenton: I didn't see how the agent could detect the subnet is being deleted when the subnet delete hasn't started yet.22:45
kevinbentoncarl_baldwin: ack. this event may have been triggered by another operation. let me see what22:46
carl_baldwinkevinbenton: BTW:  https://review.openstack.org/37279422:46
carl_baldwin^ I think this avoids the issues with the first attempt. I think this would've prevented this occurrence and the initial one when you filed the bug report.22:47
*** Leo_ has joined #openstack-neutron22:47
carl_baldwinkevinbenton: It prevents the port update from swapping out IPs so the allocation doesn't go away.22:48
carl_baldwinkevinbenton: I think it is a good idea anyway to try to not change IP allocations when this kind of update comes.22:48
kevinbentoncarl_baldwin: http://logs.openstack.org/51/371751/1/check/gate-tempest-dsvm-neutron-linuxbridge-ubuntu-xenial/6f6184e/logs/screen-q-dhcp.txt.gz22:48
kevinbentoncarl_baldwin: it looks like that port update was in reaction to its subnets changing22:48
kevinbentoncarl_baldwin: req-06c10180-b446-4905-b3d5-ae9e27ca876622:49
kevinbentoncarl_baldwin: had the lock port_update_end22:49
kevinbentoncarl_baldwin: so my patch would have deferred this reload as well22:49
kevinbentoncarl_baldwin: well maybe not, the subnets didn't change on this port update i don't think22:50
*** itsuugo has quit IRC22:50
carl_baldwinkevinbenton: I'm confused. That request *is* the port update from the agent.22:50
*** itsuugo has joined #openstack-neutron22:51
kevinbentoncarl_baldwin: it's doing that in response to it's port being updated22:51
kevinbentoncarl_baldwin: req-0a6defde-3522-4758-9eb1-05c2c41e75f422:51
*** Leo_ has quit IRC22:51
carl_baldwinkevinbenton: Its the one that caused 2003::3 to be deallocated under the subnet delete's nose.22:51
kevinbentoncarl_baldwin: (the dhcp agent is misleading a bit with the request IDs, it swaps out for new RPC calls)22:52

kevinbentonthe req is is generated on the dhcp agent23:02
kevinbentonwhen it decides to make a call to the neutron server23:03
kevinbentonunfortunately it doesn't just carry through the original request ID (req-06c10180-b446-4905-b3d5-ae9e27ca8766)23:03

*** tflynn has quit IRC23:07
kevinbentoncarl_baldwin: that's a gift from the l2 agent23:07
kevinbentoncarl_baldwin: it doesn't change out it's request IDs23:07
kevinbentoncarl_baldwin: comes from the event loop in the l2 agent from setting the status to ACTIVE23:08
*** tflynn_ has quit IRC23:08
kevinbentoncarl_baldwin: so it is strange that the DHCP agent decided to reload on a port status change23:08
carl_baldwinkevinbenton: Yeah, that seems strange.23:09

liuyulongtidwellr, ping23:35
kevinbentoncarl_baldwin: yeah, i've been meaning to get some of the context stuff cleaned up more in the agents23:35
carl_baldwinkevinbenton: there was the port status update that changed status and revision number for the port object.23:36
liuyulongtidwellr, really hard to catch you, : ), what's your local time zone?23:36
kevinbentoncarl_baldwin: get them to stop using a single request ID for everything23:36
carl_baldwinkevinbenton: That might be a nice thing.23:36
kevinbentoncarl_baldwin: realistically they should carry the request ID from the server event that triggered it if that applies23:36
kevinbentoncarl_baldwin: idealistically*23:36
carl_baldwinkevinbenton: I wonder if it reloaded allocations because the revision number bumped two revisions.23:37
kevinbentoncarl_baldwin: well it will always reload on any change right now. there's definitely room for optimization there23:37
kevinbentoncarl_baldwin: however, it looks like it called 'restart'23:37
kevinbentoncarl_baldwin: because it did a kill -923:37
kevinbentoncarl_baldwin: which it's only supposed to do if the fixed IPs changed23:38
kevinbentoncarl_baldwin: ugh, did this network have an auto address subnet on it?23:38
carl_baldwinkevinbenton: It might have. It has an ipv6 subnet. Don't know yet if it is auto-address.23:39

tidwellrliuyulong: sorry, I stepped away from my compute for a minute23:41
kevinbentoncarl_baldwin: there is some logic floating around in the agent somewhere where it ignores auto IPv6 addresses after it updates its port server side23:41
liuyulongtidwellr, https://review.openstack.org/#/c/357716/, can we land this in N cycle?23:42
*** openstackgerrit has quit IRC23:42
liuyulongtidwellr, and I've replied to you.23:42
kevinbentoncarl_baldwin: however, this isn't present in the port_update_end handler, so it could think its port changed when it actually hadn't23:42
