| lamont | is there anything mounted under chroot/proc? | 00:00 |
|---|---|---|
| infinity | Oh, derp. | 00:00 |
| infinity | llvm-* build-deps on binfmt-support. Of course. | 00:01 |
| infinity | Now I feel silly. | 00:01 |
| lamont | so umount-chroot is just broken, because it assumes that reversing the contents of /proc/mounts (which is somewhat random) will give a nicely ordered list | 00:01 |
| infinity | lamont: So, we just need smarter umount ordering, probably. | 00:01 |
| lamont | just loop | 00:01 |
| infinity | lamont: Walk tree depths. | 00:01 |
| lamont | it's saner than trying to order | 00:01 |
| infinity | (or loop) | 00:01 |
| lamont | and life is short. feel free to update the bug? | 00:01 |
| * lamont lets the panda fsck | 00:02 | |
| lamont | 210GB disk... sigh | 00:02 |
| infinity | You know, screw sorting, I bet if you just inverted the list from the grep /proc/mounts, it would solve it. | 00:03 |
| infinity | And much more elegantly. | 00:03 |
| lamont | we already do that... | 00:03 |
| lamont | and that's probably because we needed it _that_ order | 00:04 |
| infinity | I don't see it inverted. | 00:04 |
| lamont | maybe that's just my brain messing with me | 00:04 |
| infinity | This is essentially what lp-buildd does: | 00:05 |
| infinity | root@shiva:~# grep oneiric-llvm /proc/mounts | cut -d\ -f2 | xargs -r -n 1 echo | 00:05 |
| infinity | /srv/chroot/oneiric-llvm/proc | 00:05 |
| infinity | /srv/chroot/oneiric-llvm/dev/pts | 00:05 |
| infinity | s/echo/umount/ for the real deal. | 00:05 |
| infinity | /srv/chroot/oneiric-llvm/proc/sys/fs/binfmt_misc | 00:05 |
| infinity | Invert that list, bug fixed. | 00:05 |
| lamont | for now. the ordering in /proc/mounts isn't exactly scientific | 00:06 |
| infinity | It's FIFO. | 00:06 |
| infinity | Sure, a package could mount -o=remount /proc in its postinst and mess with you, but... Eww? | 00:06 |
| infinity | (I guess you could keep the loop too, but still invert the list) | 00:07 |
| infinity | Anyhow, commented on the bug and the merge request. | 00:09 |
| infinity | Reversing the order would be more efficient, but the loop is probably a safe catch-all anyway. | 00:10 |
| infinity | lamont: The plus side is that there's no "underlying issue" or processes cleverly hiding from us, just a bit of umount PEBKAC, so I'm that much happier about your hack. It will DTRT. :P | 00:13 |
| lamont | heh | 00:13 |
| lamont | thanks for digging into it | 00:14 |
| lamont | in other news, chort.buildd will shortly be another panda builder | 00:14 |
| infinity | \o/ | 00:14 |
| lamont | so if the panda isn't at 115200, what speed should I try? | 00:16 |
| infinity | That's the only speed it should be... | 00:17 |
| lamont | that's sad | 00:18 |
| infinity | lamont: Actually, regarding the same bug. No complex heuristics are required. Piping a "sort -r" between the cut and xargs will DTRT. | 00:18 |
| infinity | lamont: Cause paths sort quite nicely. :P | 00:19 |
| lamont | for the non-pathological case, yes | 00:19 |
| infinity | Build me a case where it fails? | 00:19 |
| lamont | ���������� <-- I do not like it when hitting return several times gets me that.. | 00:20 |
| infinity | I'm having BBS flashbacks. | 00:21 |
| lamont | they're only slightly faster than some of them | 00:21 |
| lamont | for the real BBS experience, you want a beaglexm or a bbg3 | 00:22 |
| infinity | And a copy of LORD. | 00:22 |
| lamont | will that even run on arm? | 00:25 |
| infinity | Under freedos under qemu, sure! | 00:26 |
| infinity | Or something equally convoluted. | 00:26 |
| infinity | Well, time to go have a birthday. I'll be around here and there on the weekend for releaseish stuff. | 00:37 |
| NCommander | infinity: happy birthday | 00:50 |
| infinity | Danke. | 00:51 |
| lamont | infinity: I just realized that serial console is somewhat overrated | 01:04 |
| lamont | until it isn't. :( | 01:53 |
| cjwatson | infinity: curl> I hadn't noticed it, but yeah, I'm probably biased. If you want to, that'd be great | 08:48 |
| cjwatson | infinity: on the umount thing, maybe umount -l would be helpful as well? | 08:48 |
| infinity | cjwatson: Already did overrides and accepted the two new udebs. | 09:51 |
| infinity | cjwatson: As for the umount thing, I'm leaving it in the hands of lamont and the launchpad team at this point, I've commented more than enough on the bug. :P | 09:51 |
| cjwatson | ta | 10:24 |
| astraljava | Hello folks, I recently added a new bzr branch for a package (lightdm-theme) for our team, ~ubuntustudio-dev. We'd like to include it in oneiric, still. Does it need an FFe? | 12:45 |
| ScottK | astraljava: Technically yes, but on matters of flavor branding we'll approve whatever you all want, so whoever is the ubuntu studio lead just needs to say it should go in. | 15:25 |
| astraljava | ScottK: Thanks, just a minute ago I got a response on -devel, though, that I should file an FFe. It's here: http://pad.lv/852623 | 15:31 |
| scott-work | ScottK: hi, ScottL here (ubuntu studio project lead) asking about getting a lightdm theme into the repos | 15:48 |
| scott-work | ScottK: anything special we would need to do? | 15:48 |
| ScottK | scott-work: Ack in the bug that you want it (I approved it for the release team based on that and then subscribe ubuntu-sponsors/find someone to upload it. | 16:07 |
| scott-work | ScottK: aye | 16:08 |
| === s1aden is now known as sladen | ||
| lamont | cjwatson: umount -l feels way too much like a total hack to me. | 20:27 |
| lamont | 18 arm builders are making a bit of a dent in the rebuild test | 20:27 |
