armaxHenryG: I am \00:06
armaxHenryG: sup?00:07
HenryGarmax: dasm's fix for unit tests is correct00:07
armaxHenryG: can you get this notarized?00:07
HenryGThough I can't pinpoint where the mock is being done00:07
armaxand faxed over to my secretary?00:07
HenryGBut I can reproduce the problem 100%00:07

armaxI think the obvious question I had was00:09
*** ChrisBenson has quit IRC00:09
*** busterswt has quit IRC00:09
armaxshould we turn all of the other Fakers?00:09
HenryGI was going to suggest that00:10
armaxdid kevinbenton have a peep on this issue?00:10
*** yuanying has joined #openstack-neutron00:10
armaxHenryG: well, it’s clearly not necessary00:10
HenryGDo you think it's in the scope of the bug/patch?00:10
armaxbut I despise the asymmetry now00:10
*** nplanel has joined #openstack-neutron00:10
armaxI wonder if there’s another way to solve the issue00:10
armaxI am not debating that the fix is indeed one00:11
armaxheres00:11
armaxI don’t fully understand why this is happening hence I feel a bit reluctant to +200:12
armaxcommit message wasn’t super insightful either00:12
armaxI am with you that I want the gate healed though00:12
HenryGYeah. Like I said, I can't find which mock is interfering.00:13

armaxthe one that flipped fixtures to using mock? though I can’t think of why that woudl be the culprit00:15
armaxor try to bisect to a good point in time00:15
armaxto see if we can nail down another potential issue00:15
armaxyou said that you can reproduce this 100%00:15
armaxbut how far back can you go?00:15
armaxuntil this starts passing?00:15

armaxI wonder if a revert is in order because I fear that we might solve one intermittent issue00:40
armaxonly to have another one show up00:40
armaxand since https://review.openstack.org/#/c/304851/ fixes only one test combination, when are we gonna stop?00:41
armaxso perhaps it’s safer to bake a better fix in the revert’s revert00:41
armaxHenryG: assuming that the culprit is indeed that one, which I think it is00:41
armaxHenryG: what you reckon?00:41

namnhHi everyone. When I see "dnsnamserver" table in neutron DB, I don't see unique contrain between "subnet_id" and "order" tables. This will have result that I can creat two dns-namesever on *one* subnet with same order. Actually, I reproduced this case when I run update dns-namesever at the same time. So I purposed a solution [1], could you review it. Allways happy for feedback https://review.openstack.org/#/c/293774/07:39

matrohonkevinbenton, I think there is already some kind of traffic interruption with current implementation, but you're right that with scheuran's patch it will be amplified09:55
scheuranmatrohon agree09:55
scheurankevinbenton, no, the vm is not yet frozen at this point09:56
scheuranit's still active on the source09:56
*** SpamapS has joined #openstack-neutron09:56
scheuranthe gap matrohon is referring to is, that the host_id is getting updated some time after migration finished, so there's a small gap where traffic is still enabled on the source, although vm already resides active on the target09:57

scheurankevinbenton, exactly10:05
matrohonkevinbenton, scheuran : I think the only way to avoid traffic interruption during migration is to have the dataplane sending traffic to both origin and dest during live-mig, and it can be done now, by taking advantage of info introduced in https://review.openstack.org/#/c/275420/10:06

*** ramishra_ has joined #openstack-neutron10:06
kevinbentonmatrohon: yes. it will require some rework on the l2 agent side to duplicate the traffic onto two tunnels and VLAN/flat networks will not work without the coordination of a switch driver10:07
kevinbentonscheuran: yeah, i think we might need to tweak the return value back to nova10:08
kevinbentonscheuran: like "destination_binding_details" or something10:08
scheurankevinbenton, yes10:08
*** ramishra_ has quit IRC10:08
matrohonkevinbenton, I  think it's a challenging issue that must be worked on independently of current scheuran's work10:09
scheurankevinbenton, and do you see a potential problem, if we simulate the portbinding in pre_live_migration, and the execute the portbinding in post_live_migration in regards of that the results coudld be different?10:09

*** mancdaz has joined #openstack-neutron10:16
kevinbentonscheuran: for example, if it's a driver with a backend and the backend isn't available10:17
kevinbentonscheuran: bind_port would probably work10:17
scheurankevinbenton, agree10:17
kevinbentonscheuran: and update_port would fail10:17
kevinbentonscheuran: but at that point it becomes a port_update error propagated back to Nova10:17
kevinbentonscheuran: i'm not sure how it reacts if the port update fails there10:17
kevinbentonscheuran: maybe it can abort10:18
kevinbentonscheuran: and migrate back10:18
scheurankevinbenton, if port update fail, the vif_binding will be set to binding_failed10:18
kevinbentonscheuran: no, those are two different things10:18
scheurankevinbenton, and nova stumbles when generating the libvirt xml in post_live_migration over that vif_type10:18
scheurankevinbenton, then instance is put into error state10:18
kevinbentonscheuran: binding_failed is something neutron sets on the port object10:18
kevinbentonscheuran: and it's not reported to nova as an API call failure10:19
*** javeriak_ has quit IRC10:19
kevinbentonscheuran: if the port_update fails like i'm talking about, Nova will get an API error back from neutron10:19
scheurankevinbenton, ok, got it!10:19
kevinbentonscheuran: so they are very different scenarios from that perspective10:19
kevinbentonscheuran: you can see this quickly if you have a neutron deployment handy. "neutron port-create somenet --binding:host_id=made-up-host"10:20
kevinbentonscheuran: the API call will return just fine with a body10:21
kevinbentonscheuran: then in the binding details you can see "binding_failed"10:21
kevinbentonscheuran: Which is probably why nova is treating it as a success and is passing it down to the xml generation10:21
scheurankevinbenton, right10:21
*** amotoki has joined #openstack-neutron10:22
scheurankevinbenton, and what would be a case where to port-update would fail? If neutron is not available?10:22
kevinbentonscheuran: if a driver uses a remote backend that is unavailable10:23
kevinbentonscheuran: like an SDN controller10:23
matrohonscheuran, kevinbenton : currently, as stated in https://review.openstack.org/#/c/274097/6/doc/source/devref/live_migration.rst "There is no rollback if failure happens in live-migration and post-live-migration stages"10:23
scheurankevinbenton, ok10:24
matrohonkevinbenton, are you suggesting we should introduce a chack on the binding details to revert the live-mig in cas of binding failure?10:24
openstackgerritKevin Benton proposed openstack/neutron: Add exponential back-off RPC client  https://review.openstack.org/28059510:24
*** yamamot__ has quit IRC10:25
kevinbentonmatrohon: no, just to handle the case when the final port-update fails10:25
kevinbentonmatrohon: because if we do the bind_port test ahead of time like i proposed, we shouldn't need to worry about the binding details being 'binding_failed'10:25
scheurankevinbenton, how would the api result look like in a case where the port update fails?10:26
kevinbentonscheuran: HTTP error code10:26
scheuranok10:27
scheurankevinbenton, there was another idea raised in the ml2 group for this whole topic - during migration we could bind a port to two hosts (like a DVR port can today). How do you think about this?10:27

kevinbentonscheuran: which the neutronclient converts to an exception IIRC10:27
*** nmagnezi has quit IRC10:27
matrohonkevinbenton, except if the bind_port is not accurate, since it doesn't seem to really call an externel sdn controller. At least that's what I understand from your previous statements10:27
*** hdaniel has joined #openstack-neutron10:28
*** kengo_sakai_mba has joined #openstack-neutron10:28
kevinbentonmatrohon: it won't become more accurate during the regular binding though. either it will select a correct type or return binding_failed10:28
kevinbentonscheuran: that's possible too10:29
kevinbentonscheuran: but it would be a mechanism driver API change10:29
kevinbentonscheuran: and most drivers wouldn't support it10:29
*** johnsom_ has joined #openstack-neutron10:30
scheurankevinbenton, yes, makes sense10:30

openstackgerritJohn Schwarz proposed openstack/neutron: Remove auto_schedule_routers codepath  https://review.openstack.org/28548010:30
kevinbentonscheuran: it would be nice if DVR ports weren't a special case regardless of this particular migration issue10:30
matrohonscheuran, kevinbenton : I really advocate for this since it would clean up the DVR code too and would help in HA ports in l2pop case too10:31

haypohello. i have a serie of 3 patches to port Neutron LBaaS to Python 3: https://review.openstack.org/#/c/288413/ - they already got a +2 from ihrachys, here is someone else available to review them and help me to port this code to py3?11:45
*** ianw has joined #openstack-neutron11:46
haypoit looks like Neutron LBaaS is the last huge Neutron component which is not compatible with python 3 yet11:46
ihrachyshaypo: maybe also try #openstack-lbaas11:46
ihrachyshaypo: fwaas and vpnaas done?11:46
haypooh, there is a dedicated channel? i will try there ;)11:46
ihrachysyeah, they spinned it off for some reason11:46
*** scheuran has joined #openstack-neutron11:46
haypoaccording to https://wiki.openstack.org/wiki/Python3#OpenStack_applications_.28tc-approved.29 yes, FWaaS & VPNaaS unit tests pass on py311:47

*** slaweq has joined #openstack-neutron11:47
*** mwagner_lap has joined #openstack-neutron11:48

*** links has joined #openstack-neutron11:50
haypoihrachys: you can choose which services run on py3 or not11:50
haypoihrachys: the best would be to run all neutron services on py3, and then fix failures one by one, as usual ;)11:50
ihrachyshaypo: how do we achieve that? setup.py install called with proper version?11:50
haypo(i mean that keystone, nova, etc. can still run on py2)11:51

haypoihrachys: but i didn't try yet11:51
ihrachyshaypo: sure. the question is whether we don't rush too much. it puts dev burden on neutron, and if it will take nova and others another 5 years to do the switch, we could as well wait a bit.11:51

haypoHenryG: neutron-lib is green (unit tests pass on py3) on https://wiki.openstack.org/wiki/Python3#OpenStack_Libraries11:53
*** nmagnezi has quit IRC11:54
HenryGgreat11:54
*** boden has quit IRC11:54
HenryGhaypo: we are also aiming at 100% code coverage for unit tests, so that should help keep us honest11:54
haypoHenryG: let me check neutron-lib. tox.ini runs all unit tests on py34 & it has a *voting* python34 gate job. so it's fine11:55
haypoHenryG: oh, i'm 100% *sure* that functional & integration tests will show us new and complex bugs specific to py3, trust me ;)11:56
HenryGhaypo: I don't doubt it :)11:56
HenryGhaypo: What does it take to claim it is a universal wheel?11:57
*** kawa2014 has joined #openstack-neutron11:58
haypoHenryG: since we use six, hum, it should be ok to provide the same tarball/wheel for py2 & py311:58
haypoHenryG: but i don't know for dependencies11:58
*** pradk has quit IRC11:59
haypoHenryG: you have to check that we mark correctly deps specific to py2 or py3 using env markers11:59
haypoand i doubt that the whole python ecosystem understands "well" env markers, it's still something "new" (1 or 2 years old)11:59

garykbut i suggest that you speak with kevinbenton12:06
*** jckasper has joined #openstack-neutron12:06
haypoHenryG: it's probably safe to enable universal wheel on neutron-lib. but in case of doubt, it's probably safer to disable this feature. it's ok to have one package for py2 and another for py312:06
ajogaryk, kevinbenton , look for "veth" in here: https://bugs.launchpad.net/neutron/+bug/156096312:06
openstackLaunchpad bug 1560963 in neutron "[RFE] Minimum bandwidth support (egress)" [Wishlist,Confirmed]12:06
haypoHenryG: as i said, the remaining annoying point are dependencies different between py2 & py3, and the bad state of packaging tools in python (outdated tools don't handle well deps specific to a python version)12:07
*** yfried has quit IRC12:07

ajothe other part is not clear12:16

ajoor just an error of implementation12:17

ajoihrachys, it maches with the documentations and their recomendation of using 10% burst12:17
ihrachysanyhow, the point is, if that was a legit behaviour before, should we leave it configurable in case you need to run it on an old ovs?12:17
ajo10% burst does not work12:17
ajoihrachys, yes, I discussed that with kevin12:17
ajothe plan would be12:17
ajointroducing a sanity check, to see how ovs sets tc policing values12:18
ajoand then a config flag12:18
ihrachysoh ok, as long as we care about it already, I am good12:18
ajoor may be just checking the version where that's merged12:18
ajoyes, let me see how the ovs-dev patch resolves12:18
ajoand I will add the logic & config option to ovs12:19
ajoihrachys, what worries me, is, the policies already set by customers...12:20
ajobut I don't see an easy solution for that12:20
ajowe can add a switch to /8 the burst before giving it to ovs, to set the "real burst"12:20
ajobut policies that were working before because of the bug, will stop working12:20
ajowell, will work worse12:20
ajoits' an easy fix for the admin, as long as it's documented, may be in release notes12:21

jlibosvaamuller: I missed this little but apparently important "if statement": https://github.com/openstack/neutron/blob/master/neutron/agent/ovsdb/native/connection.py#L65 given that the process runs several tests and connection is class attribute, I think the self.run thread was called in the first test using native interface, right? :)13:37

ajojlibosva, I'm not sure, but generally the userland side is less problematic13:39

amullerjlibosva: how do you mean?17:58
jlibosvaamuller: if I call addCleanup(function_that_produces_logs), will I see them in log from the test17:59
amullerjlibosva: yeah we log cleanups 100%17:59
jlibosvaamuller: ok, second question, why does exclusive_resources as the only test in functional suite uses DietTestCase?17:59
*** woodburn has joined #openstack-neutron18:00
jlibosvaI write like retard18:00
amullerjlibosva: well I have a patch that changes that so that it produces logs18:00
amullerjlibosva: but the reason I made those inherit from DietTestCase is that aside from logging they don't need anything from the functional base classes18:00
jlibosvaamuller: I'm going through tons of logs and the last time ovsdb produces log from that thread it makes is from exclusive_resources test18:01
amullerjlibosva: there's a lot of tests under the functional tests dir that don't inherit from the functional tests base class18:01
jlibosvaamuller: I'm not blaming it, just sayin' :)18:01
amullerjlibosva: that's interesting18:01
jlibosvaamuller: I was thinking more like DietTestCase does some cleanup that breaks connection to ovsdb18:01
jlibosvalooking at it now18:02
*** ildikov has quit IRC18:02
amullerjlibosva: why would ovsdb do anything during those tests18:02
amullerjlibosva: they don't invoke ovs18:02
amullerjlibosva: and also root_helper wouldn't be used18:02
jlibosvaamuller: it makes sense that it produces logs there, let me explain18:02
jlibosvaamuller: we run some ovsdb native interface tests before exclusive_resources and ovsdb connection is a class attribute18:03
*** nyechiel_ has quit IRC18:03
jlibosvaamuller: this Connection object, when started for the first time spawns a thread, run() method that runs in the loop18:03
jlibosvaamuller: the test don't cleanup this connection so connection to ovsdb remains open as it's still the same python process18:04
*** armax has quit IRC18:04
jlibosvaamuller: hence we will still get logs from the other thread that runs in a loop18:04
jlibosvaamuller: even if we don't use ovs at all18:04
jlibosvaamuller: maybe we should close the connection as part of cleanup in tests using ovsdb native interface18:05

amullerjlibosva: ok it seems like you really narrowed it down18:20
