| haypo | hello. as i wrote in https://review.openstack.org/#/c/322195/ : backup.test_backup_models test fails randomly. i would like to try to reproduce the issue locally, but i'm not sure how to run the unit test? | 06:45 |

| haypo | amrith: hello. i saw that Petr Malik ran the Jenkins job multiple times on my https://review.openstack.org/#/c/322195/ "Run Python 3 unit tests in parallel" change, i understood that it was to ensure that the job was stable | 08:32 |
| haypo | amrith: i noticed that backup.test_backup_models was unstable and so i blacklisted it on python 3, until we understand why | 08:33 |
| haypo | amrith: since i removed it (removed in patch set 10), jenkins succeeded twice which is good :) | 08:34 |
| haypo | amrith: i'm trying to say that i wasn't 100% confident that my change was stable, but without backup.test_backup_models it looks like it *is* now stable ;) | 08:34 |

| amrith | haypo, to run the unit test locally I run python -m testtools.run ... test class ... | 10:41 |
| amrith | I don't know how you'd do this in python34 or whether the same thing woudl work | 10:42 |
| amrith | i notice that there's only one patch remaining to merge on the python34 blueprint; I assume you'll be pushing up more? | 10:42 |
| amrith | you should read the notes from yesterday's trove meeting and https://review.openstack.org/#/c/332933/ | 10:43 |
| haypo | amrith: well, using testtools.run & tox -e py34, backup.test_backup_models doesn't fail here... | 10:44 |
| haypo | amrith: should i setup a database to run the unit test? | 10:44 |
| amrith | not to run unittests | 10:45 |
| amrith | but is it a unit test that is unstable? | 10:45 |

| amrith | are you talking about the failure: | 10:46 |
| amrith | backup.test_backup_models.BackupORMTest.test_list_for_instance | 10:46 |
| amrith | http://logs.openstack.org/95/322195/5/check/gate-trove-python34-db/81f9f68/console.html.gz#_2016-06-15_09_15_18_704 | 10:46 |
| haypo | amrith: backup.test_backup_models failed once on python 3 for an unknown reason, http://logs.openstack.org/95/322195/9/check/gate-trove-python34-db/65710dc/ | 10:46 |
| haypo | amrith: i chose to blacklist it to investigate later | 10:47 |
| haypo | amrith: hum. http://logs.openstack.org/95/322195/5/check/gate-trove-python34-db/81f9f68/console.html.gz#_2016-06-15_09_15_18_704 failed with ...CREATE TABLE..., | 10:48 |
| amrith | <blanket-disclaimer. I THINK> | 10:48 |
| amrith | the issue you have is that the parallelism is somehow broken | 10:48 |
| haypo | but http://logs.openstack.org/95/322195/9/check/gate-trove-python34-db/65710dc/ failed 3 times : 2 ALTER TABLE, 1 CREATE TABLE | 10:48 |
| amrith | and multiple threads are running through migrations | 10:48 |
| amrith | and are attempting to recreate the trove schema | 10:48 |
| amrith | What's the number in {%d} | 10:48 |
| amrith | is that the test thread ? | 10:49 |
| haypo | "{%d}" <= i don't know what you are talking about | 10:49 |
| amrith | if so, then I'd look for example at the failure at http://logs.openstack.org/95/322195/9/check/gate-trove-python34-db/65710dc/console.html#_2016-06-22_03_32_06_707769 | 10:49 |
| amrith | in the output line | 10:49 |
| amrith | 2016-06-22 03:31:58.535132 | {5} taskmanager.test_vertica_clusters.VerticaTaskManagerStrategyTest.test_task_manager_api_class [0.000442s] ... ok | 10:49 |
| amrith | What is {5} | 10:49 |
| amrith | 2016-06-22 03:27:41.442187 | {5} backup.test_backup_models.BackupCreateTest.test_create_backup_swift_token_invalid [0.140276s] ... FAILED | 10:50 |
| amrith | what is {5} | 10:50 |
| haypo | amrith: ah, probably the worker process identifier from 0 to 7 | 10:50 |
| amrith | So I'd see what test that ran before that already created the table in question | 10:51 |
| amrith | or already performed the alter table in question | 10:51 |
| amrith | the test isn't stable | 10:51 |
| amrith | because the testing framework is likely picking tests to run in a non-deterministic way | 10:51 |
| haypo | amrith: python 2.7 also runs tests in parallel using 8 processes, http://logs.openstack.org/95/322195/9/check/gate-trove-python27-db/190e9d4/console.html | 10:51 |
| amrith | yes, but maybe with different dependencies | 10:51 |
| amrith | and a different (potentially) safe sequence | 10:51 |
| amrith | maybe the problem exists in py27 | 10:51 |
| haypo | but python 3.4 is more verbose *thanks to* os-testr | 10:52 |
| amrith | but we just don't hit it | 10:52 |
| amrith | for some other reason or reasons | 10:52 |
| amrith | I'm not pointing to py34 being the problem | 10:52 |
| amrith | maybe the dependencies are wrong | 10:52 |
| haypo | amrith: i wouldn't be surprised if python 2 already has the bug | 10:52 |
| amrith | eventually, you are attempting to do something that has already been done | 10:52 |
| amrith | creating a table | 10:52 |
| haypo | for me, it became common to "find" bugs with python 3 which already existed before | 10:52 |
| amrith | altering a table | 10:52 |
| amrith | that is good | 10:52 |
| amrith | i think that's what testing is about | 10:52 |
| haypo | it took us 2 weeks to identify a race condition in glance, the bug exists in python 2 as well | 10:52 |
| amrith | 2 weeks to find a race condition is nothing | 10:53 |
| amrith | hard ones take years | 10:53 |
| haypo | amrith: does trove use a real mysql database? | 10:53 |
| haypo | "hard ones take years" haha | 10:53 |
| amrith | in these tests it uses sqllite | 10:53 |
| amrith | what do you mean 'haha' | 10:53 |
| haypo | amrith: haha = lol | 10:53 |
| haypo | in french | 10:53 |
| amrith | well, I know what it means | 10:53 |
| amrith | I guess you've never dealt with bugs like that | 10:53 |
| haypo | amrith: each test cannot use a separated and temporary database? | 10:54 |
| amrith | it would be kind of expensive | 10:54 |
| haypo | ah | 10:54 |
| haypo | so you should maybe disable parallelism :) or put a lock | 10:54 |
| haypo | amrith: for following changes: i'm waiting that you approve my latest py3 trove change ;) | 10:55 |
| amrith | i see now why you think race conditions that take years to find are a laughing matter. | 10:56 |
| amrith | The last car I owned was paid for by finding one such bug. | 10:56 |
| amrith | or shall we say explaining one such bug. | 10:56 |
| haypo | if such bug is blocking a project, you can fix it quickly by investing more resources on it | 10:58 |
| haypo | usually, such bug is so rare that nobody cares | 10:58 |
| haypo | for example, here a single recheck worls around it ;) | 10:58 |
| haypo | works* | 10:59 |
