| Saviq | pitti, hey, does this adt-run(schroot) error mean anything to you http://pastebin.ubuntu.com/9251865/ ? | 09:45 |
|---|---|---|
| pitti | Saviq: I'm afraid not; if you can reproduce it, would you mind filing a bug with reproduction instructions? | 09:47 |
| pitti | Saviq: apparently it did copy up teh stderr file from the testbed (line 20 in pastebin) | 09:47 |
| pitti | so I'm not sure why it's missing | 09:47 |
| Saviq | pitti, another thing is that it didn't drop me to shell, even though I asked for it | 09:48 |
| pitti | Saviq: yeah, as it got that unexpected error | 09:49 |
| pitti | Saviq: the "drop into shell" happens after displaying stderr | 09:50 |
| Saviq | pitti, ah | 09:51 |
| Saviq | pitti, any package in particular I could use to verify that it's not my packages' fault? | 09:51 |
| pitti | Saviq: my preferred guinea pig is usually d-conf or libpng | 09:52 |
| pitti | Saviq: as they are fast | 09:52 |
| Saviq | pitti, ok | 09:52 |
| pitti | adt-run libpng --- schroot sid | 09:52 |
| pitti | Saviq: but it doesn't matter much | 09:52 |
| pitti | Saviq: so, this is definitively not the "fault" of your package, it might just trigger something funky | 09:52 |
| Saviq | pitti, yup, understand | 09:53 |
| pitti | Saviq: have you used the schroot runner before? | 09:53 |
| Saviq | pitti, no, I've been setting up proper for adt for the first time, qemu runner seems to have worked better, but I got schroots laying around for sbuild so thought would use those | 09:54 |
| pitti | Saviq: yeah; I use them all the time, so I rather suspect that you and I have some slightly different schroot setups | 09:54 |
| Saviq | pitti, hmm same happens with libpng | 09:54 |
| pitti | and schroot is used in production on ci.debian.net, too | 09:54 |
| Saviq | pitti, I wonder, eatmydata or something | 09:54 |
| pitti | yeah, I suspected as much (not package specific) | 09:55 |
| * Saviq drops the custom commands from schroot | 09:55 | |
| pitti | Saviq: can you try --- ssh -d <schroot_name> to get debug information from the schroot runner? | 09:56 |
| pitti | Saviq: does that happen with other schroots? or just unity8-amd64-shm | 09:56 |
| Saviq | pitti, all of them | 09:56 |
| Saviq | pitti, you mean schroot -d, no ssh -d? | 09:57 |
| pitti | Saviq: err yes -- autofinger | 09:57 |
| Saviq | pitti, http://paste.ubuntu.com/9265598/, that's from `adt-run libpng -d --- schroot -d vivid-amd64` | 09:57 |
| === chihchun is now known as chihchun_afk | ||
| Saviq | pitti, here's my schroot config, tried without command-prefix, same thing... anything springs to mind http://paste.ubuntu.com/9265616/ ? | 09:59 |
| pitti | Saviq: hm, perhaps the eatmydata; it might not flush the stderr file to disk (especially not when it's a 0-byte file) early enough? | 10:00 |
| pitti | Saviq: otherwise my sid schroot uses overlayfs and directory, too | 10:01 |
| pitti | (most of my other schroots are tarballs) | 10:01 |
| Saviq | pitti, yeah, I tried to drop the command-prefix, didn't help | 10:01 |
| Saviq | weeird, /me will create a new chroot | 10:01 |
| pitti | Saviq: in /usr/share/autopkgtest/python/VirtSubproc.py could you apply http://paste.ubuntu.com/9265758/ and see if that helps? | 10:06 |
| pitti | Saviq: i. e. if it's some kind of file system race, or some logic error | 10:06 |
| pitti | (this isn't a proper solution of course, just a quick test) | 10:07 |
| Saviq | pitti, same thing I'm afraid | 10:08 |
| pitti | Saviq: ok, that makes it more likable :) | 10:09 |
| pitti | Saviq: ooh! libpng also failed for you, right? | 10:11 |
| pitti | Saviq: can you please try this: | 10:12 |
| pitti | schroot -c sid -u root -- su -s /bin/bash -c 'whoami' | 10:12 |
| pitti | erk | 10:12 |
| pitti | schroot -c vivid-amd64 -u root -- su -s /bin/bash michal -c 'whoami' | 10:12 |
| pitti | Saviq: ^ this | 10:12 |
| pitti | Saviq: i. e. maybe it's the su itself which fails (can't resolve your user name), this would explain why the -stdout/err files are not created and libpng fails | 10:14 |
| Saviq | pitti, it returned my uid | 10:15 |
| Saviq | "michal" | 10:15 |
| Saviq | s/uid/username/ | 10:16 |
| === chihchun_afk is now known as chihchun | ||
| pitti | Saviq: ack, so that one works | 10:23 |
| pitti | schroot -c vivid-amd64 -u root -- su -s /bin/bash michal -c 'set -e; export USER=`id -nu`; . /etc/profile >/dev/null 2>&1 || true; . ~/.profile >/dev/null 2>&1 || true; whoami' | 10:26 |
| pitti | Saviq: ^ can you try this? | 10:27 |
| Saviq | pitti, retcode 1 | 10:27 |
| pitti | a-haa! | 10:27 |
| Saviq | ;) | 10:27 |
| pitti | schroot -c vivid-amd64 -u root -- su -s /bin/bash michal -c 'set -ex; export USER=`id -nu`; . /etc/profile >/dev/null || true; . ~/.profile || true; whoami' | 10:28 |
| pitti | Saviq: ^ | 10:28 |
| Saviq | pitti, works | 10:28 |
| Saviq | pitti, ah | 10:28 |
| Saviq | pitti, byobu | 10:28 |
| Saviq | daaamit | 10:28 |
| Saviq | pitti, yeah, it's byobu | 10:29 |
| Saviq | if I disabled byobu in my session, it's all back in order | 10:29 |
| pitti | Saviq: ah, interesting; that hooks itself into ~/.profile? | 10:30 |
| Saviq | pitti, yeah | 10:30 |
| Saviq | _byobu_sourced=1 . /usr/bin/byobu-launch | 10:30 |
| Saviq | is what it adds | 10:30 |
| pitti | Saviq: ah, I wonder if that should only be done on interactive shells | 10:32 |
| pitti | Saviq: so apparently the || true for sourcing doesn't work as it should? what did you see when you ran this command without the stdout/err redirection? | 10:33 |
| Saviq | pitti, http://pastebin.ubuntu.com/9266194/ | 10:34 |
| Saviq | pitti, I'll talk to Dustin on that, thanks for the interactive debugging session | 10:34 |
| pitti | Saviq: interesting, thanks; could you still file a bug about it, please? it seems ". file || true" doesn't work | 10:35 |
| Saviq | pitti, yup, will do | 10:35 |
| pitti | cheers | 10:35 |
