| tomwardill | I need someone who's better at bash parsing than I am: | 14:26 |
|---|---|---|
| tomwardill | lxc-attach -n "$container_name" -- env -u LANG USER=buildbot $PWD/bin/with-xvfb $PWD/bin/test -vvv --shuffle --subunit "$@" | subunit-1to2 | 14:26 |
| tomwardill | how do I make that pipe be part of the subcommand? | 14:26 |
| tomwardill | currently it's attempting to pipe the output of lxc-attach into it | 14:26 |
| cjwatson | Does lxc-attach produce some extra stuff as well as the output of the underlying command then? | 14:28 |
| cjwatson | But also, that seems backwards | 14:28 |
| cjwatson | If you want v2 output you could just use --subunit-v2. I thought you needed to produce v2 for testrepository and then use subunit-2to1 to convert it into something the master understands, though | 14:29 |
| SpecialK|Canon | tomwardill: quote the bit after the --? | 14:29 |
| cjwatson | It gets a bit awful with "$@" though | 14:29 |
| cjwatson | Better to avoid that if we can | 14:30 |
| cjwatson | BTW the other thing I noticed is that lpbuildbot/bzrbuildbot/subunittest.py is probably going to need to gain v2 support | 14:31 |
| cjwatson | Oh, except that's only when we upgrade the master, never mind | 14:31 |
| tomwardill | yeah, that's my backup plan for if the subunit-2to1 doesn't work | 14:31 |
| tomwardill | (yes, that previous one was backwards) | 14:32 |
| cjwatson | If lxc-attach is producing extra output, can you get it to shut up by adding the -q option? | 14:33 |
| cjwatson | I think we want lp-setup-lxc-test to be producing a clean subunit stream without any extra guff anyway | 14:35 |
| tomwardill | it's more that my output looks something like this: https://usercontent.irccloud-cdn.com/file/h1zsmSsw/image.png | 14:35 |
| cjwatson | Right, I get that, I'm just wondering why you need to avoid the output of lxc-attach being passed to subunit-2to1 | 14:36 |
| cjwatson | It could only be a problem if lxc-attach is doing more than just passing through stdout from its inferior command | 14:36 |
| tomwardill | I don't know tbh, I've got myself confused | 14:37 |
| * tomwardill starts at the beginning again | 14:38 | |
| * cjwatson makes an LXC container to test. Been ages since I had one of these ... | 14:38 | |
| tomwardill | I could probably just ship you my worker lxdvm | 14:39 |
| cjwatson | Heh, I think lxc-create will still be faster | 14:40 |
| tomwardill | I suspect this might end in having to upgrade lpbuildbot/bzrbuildbot/subunittest.py with v2 | 14:41 |
| tomwardill | (as you suggested) | 14:41 |
| cjwatson | Tricky because praseodymium doesn't have the python-subunit version needed for that | 14:41 |
| cjwatson | I think it should be avoidable in this pass | 14:41 |
| cjwatson | (We can backport python-subunit if we have to, but let's try to avoid that work just now) | 14:41 |
| tomwardill | cjwatson: my current lp-setup-lxc-test https://pastebin.canonical.com/p/Q2ZDHtyf9G/ | 14:42 |
| tomwardill | based on a xenial worker/test-lxc | 14:42 |
| cjwatson | OK | 14:42 |
| tomwardill | oh hey, got postgres to behave | 16:43 |
| tomwardill | now just the subunit stuff to solve | 16:43 |
| tomwardill | oh no, it's only partially behaving | 16:44 |
| tomwardill | boo | 16:44 |
| tomwardill | nope, postgres still refusing to start when run via buildbot. Works fine by hand | 16:59 |
| * tomwardill stares at it | 16:59 | |
