| kong | rakhmerov: for everyone's concern about the event trigger feature, I added a filter layer in event engine service, leave the decision to operators for what information that end users can see from notification. Please take a look if that is right way to go. | 02:17 |

| kong | The other question is, the library release freeze date will be Aug 25. I want to discuss with you about what time is preferable for python-mistralclient release? | 02:20 |

| rakhmerov | kong: awesome, I like this filter idea | 04:29 |
| rakhmerov | kong: I see no problem with releasing client on 25th or earlier, seems like we don't have any hot features that we would need to include into client in N-3 | 04:30 |
| rakhmerov | maybe someone else will raise something up though.. | 04:31 |

| brunograz | Hi all, I'm trying mistral in a devstack environment and I would like to know where would be the best place to get some help from you guys | 07:21 |

| brunograz | rakhmerov: sure. Mistral config: http://pastebin.com/DJsxwiig | 08:33 |
| brunograz | mistral version: mistral 2.0.1 | 08:33 |
| brunograz | keystone version (not sure if it is correct): 10.0.0 | 08:33 |
| brunograz | here is the error - http://pastebin.com/P9CCr30Q | 08:36 |
| rakhmerov | I see | 08:37 |
| rakhmerov | config looks generally ok to me | 08:39 |
| rakhmerov | ddeja, kong, nmakhotkin, rbrady, others: any guesses? | 08:40 |
| ddeja | rakhmerov: looking | 08:40 |
| rakhmerov | thanks | 08:41 |
| ddeja | rakhmerov: Not sure if it is the problem, but in the trace there is "line 112, in get_keystone_endpoint_v2" | 08:42 |
| ddeja | but then keystonclient/v3 is used | 08:42 |
| ddeja | some bug, or something misconfigured? | 08:42 |
| rakhmerov | it should be fine because v3 is explicitly used only for trusts | 08:43 |
| ddeja | OK | 08:44 |
| brunograz | I'll have a loko then and try to redeploy devstack. It could be that I missed something. | 08:46 |
| brunograz | I'll revert to you in case it work in a new deployment :) | 08:47 |
| ddeja | brunograz: can you try to delete VM fron nova directly from CLI using login, password etc. from mistral conf? Maybe mistral user canno't remove VMs.. | 08:51 |
| brunograz | ddeja: sure. give me a sec | 08:52 |
| brunograz | ddeja: Request to delete server f06c985a-8354-40f6-8f3b-ff8017368320 has been accepted. | 08:57 |
| ddeja | OK, so there is no problem with credentials | 08:58 |
| brunograz | ddeja: I'll deploy Mistral in a diff VM and check if it works | 08:58 |
| ddeja | brunograz: OK | 08:59 |
| brunograz | maybe there was an error with this installation | 08:59 |
| brunograz | then I'll get back to you guys | 08:59 |

| jaosorior | Hey guys, any idea on how to get the output of mistral-db-manage populate to some log file? would like to add such an option to puppet-mistral. | 11:35 |
| *** dprince has joined #openstack-mistral | 11:43 | |
| rakhmerov | jaosorior: afaik, no such option | 11:47 |
| rakhmerov | ddeja: Dawid, I replied to https://review.openstack.org/#/c/356227/ | 11:47 |
| jaosorior | rakhmerov: so currently the only option is to pipe the output to a file? | 11:47 |
| rakhmerov | yes, seems like | 11:48 |
| rakhmerov | what info are interested in exactly? | 11:48 |
| rakhmerov | what's been inserted into DB? | 11:48 |
| rakhmerov | if so, please file a DB, we'll add necessary logging | 11:49 |

| rakhmerov | ok | 11:51 |
| ddeja | rakhmerov: +2 +W :) | 11:51 |
| rakhmerov | thanks | 11:52 |
| rakhmerov | ddeja: just FYI, I'm still trying to make 'join' work properly w/o global execution locks | 11:52 |
| rakhmerov | mysql is giving me a lot of pain | 11:53 |
| ddeja | so that the 'lock' table wouldn't be use? | 11:53 |
| ddeja | or using the lock table? | 11:53 |
| ddeja | rakhmerov: OH, and I just remember, I can't participate in todays meeting. Today is my first wedding anniversary | 11:55 |
| rakhmerov | ooh, congratulations! | 11:55 |
| rakhmerov | ok :) | 11:55 |

| nmakhotkin | hi rakhmerov, ddeja | 11:55 |
| ddeja | nmakhotkin: hi | 11:56 |
| rakhmerov | yeah, that lock table is used now in the solution I'm trying to finish | 11:56 |
| rakhmerov | it's basically finished but there's still some issues with it | 11:56 |
| rakhmerov | nmakhotkin: hi | 11:56 |
| ddeja | rakhmerov: OK | 11:56 |

| brunograz | Hi all, just to let you know that I tried again in a new devstack deployment and the error persists | 13:10 |
| *** toddjohn has joined #openstack-mistral | 13:10 | |
| brunograz | I'm trying to start a workflow (delete instance) using the Cron trigger but whenever the worflow is executed I get the same error - Cannot authorize API client. | 13:11 |
| nmakhotkin | hi brunograz! | 13:11 |
| nmakhotkin | have you tried to run it directly? (without using cron trigger) | 13:12 |
| brunograz | yes, and that works | 13:12 |
| nmakhotkin | ok | 13:12 |
| nmakhotkin | it seems that the exact reason is keystone trusts | 13:13 |
| nmakhotkin | they are used only by cron triggers | 13:13 |
| nmakhotkin | but it worked fine about a couple months ago :) | 13:14 |
| nmakhotkin | rakhmerov, what do you think? | 13:14 |

| rbrady | rakhmerov: do you have a list of the mysql / performance bugs so we can take a look? | 17:01 |
| rakhmerov | answered in openstack-meeting | 17:02 |
| rakhmerov | git history can probably give some understanding | 17:02 |
| rakhmerov | in fact, there's only one serious thing I'm now observing on my local tests | 17:02 |
| rakhmerov | I get into some exotic deadlock when I have a lot of parallel tasks joined into one branch | 17:03 |
| *** toddjohn has quit IRC | 17:03 | |
| rakhmerov | I use something like a DB semaphore based on READ COMMITTED properties and it works well until I reach a number of transactions something like 170-180 | 17:04 |
| rakhmerov | after that something weird happens and it just gets stuck, nothing is moving forward | 17:04 |
| rakhmerov | maybe I'm hitting some DB limit but I just would like to understand exactly what. Because DB monitoring doesn't show there's actually some critical problem on DB side | 17:05 |
| rakhmerov | anyway, I keep investigating | 17:05 |
| rakhmerov | I said 'exotic' because DB doesn't detect it as a deadlock | 17:06 |
| *** tonytan4ever has joined #openstack-mistral | 17:06 | |
| rakhmerov | it may be cross-component deadlock | 17:06 |
| *** tonytan_brb has quit IRC | 17:08 | |
| rakhmerov | rbrady: so if you know somebody with mysql expertise who could potentially advise something I'd really appreciate that | 17:09 |
