| antarus | Does the installer support GPT ? | 00:39 |
|---|---|---|
| cjwatson | Yes | 00:40 |
| antarus | I'm not super familiar with GPT | 00:44 |
| antarus | but it appears that it is not being configured correctly, grub is telling me "This GPT partition label has no BIOS Boot Partition; embedding won't be possible!." | 00:44 |
| antarus | then later on /usr/sbin/grub-setup: error: cannot read `/grub/core.img' correctly. | 00:45 |
| cjwatson | Are you using manual partitioning? How old an image are you using? | 00:45 |
| antarus | this bug was filed march 23, we sync images about 12h after you release them | 00:45 |
| antarus | let me double check the preseed | 00:45 |
| cjwatson | That's odd because I added a big warning to the partitioner before that that complains if you don't have such a partition. | 00:45 |
| cjwatson | Although if you're preseeding a partitioning layout then it's your job to create such a partition. | 00:46 |
| antarus | we are using partman_auto/expert_recipe | 00:46 |
| antarus | (it was like that when I got here, etc..) | 00:46 |
| antarus | so we need to change our preseed then yes? | 00:46 |
| cjwatson | 1 1 1 free $iflabel{ gpt } $reusemethod{ } method{ biosgrub } . | 00:47 |
| antarus | excellent | 00:47 |
| cjwatson | is the bit from the default atomic recipe | 00:47 |
| cjwatson | I'd probably put it at the start | 00:47 |
| antarus | as always your assistance was quick and greatly appreciated ;) | 00:47 |
| cjwatson | thank me when it works ;-) | 00:47 |
| antarus | yes yes ;p | 00:48 |
| antarus | hrm, any idea if this will work fine on non-gpt as well? | 00:59 |
| cjwatson | antarus: yes, the $iflabel{ gpt } bit arranges for this to be a no-op elsewhere | 01:30 |
| antarus | ahhh | 01:38 |

| antarus | oh dear lord, did we build our own partitioner? | 02:59 |
| * antarus ughs | 02:59 | |
| antarus | the past, I hate it | 02:59 |
| cjwatson | this is why we went to enormous effort to reuse d-i's partitioner in ubiquity, despite the complexity induced by doing so | 03:01 |
| cjwatson | maintaining two => ftl | 03:01 |
| antarus | I love it when my machine is misconfigured to not print to console, and my syslogs stopped 30 minutes ago with no errors ;p | 03:03 |
| antarus | Used to install additional, non-standard d-i components (udebs). It will check if anna has already been run. If it has, the component is unpacked immediately; if it has not, it will be scheduled for installation when anna is run. | 03:08 |
| antarus | aha | 03:08 |
| antarus | I wonder if anna moved around in d-i between L and P | 03:09 |
| antarus | cjwatson: is there a document detailing the steps of the installer? | 03:12 |
| antarus | ahh I guess main-menu is dynamically assigned.. | 03:13 |
| antarus | bleh | 03:13 |
| cjwatson | antarus: http://d-i.alioth.debian.org/doc/internals/ | 03:16 |
| cjwatson | not totally up to date but pretty good | 03:17 |
| cjwatson | I don't believe anna moved | 03:17 |
| antarus | it wouldn't surprise me if this never worked either ;p | 03:17 |
| antarus | I guess the quickest thing to do is take the initrd and just bust it open | 03:18 |
| antarus | oh look | 03:39 |
| antarus | I pulled some lucid logs and it never worked there either | 03:39 |
| * antarus sighs | 03:39 | |
| gema | does anyone know where I can have a look at the code of ubiquity_webcam_play ? | 10:16 |
| cjwatson | gema: lp:ubiquity, src/webcam/webcam.c | 10:18 |
| gema | cjwatson: thanks | 10:19 |
| gema | cjwatson: we've set ulimit -c unlimited but after sending SIGILL or SIGSEV there is no core dump from ubiquity on the live install, is there anything we are missing? | 10:30 |
| gema | cjwatson: I am trying to leave enough info on bug 966294 so that you guys can actually fix it, it has to do with the camera | 10:31 |
| ubot2 | Launchpad bug 966294 in ubiquity "Precise AMD64 Desktop beta 2 image hangs during an install" [Undecided,New] https://launchpad.net/bugs/966294 | 10:31 |
| cjwatson | It might have a current directory it can't write to. | 10:31 |
| cjwatson | However surely the crash reporting thing should get hold of the core dump regardless. | 10:31 |
| gema | cjwatson: we are running it manually from ~ , does it change its current directory? | 10:32 |
| gema | cjwatson: we are trying to make it coredump with a signal | 10:32 |
| cjwatson | Not explicitly | 10:32 |
| cjwatson | Anything in /var/crash afterwards? | 10:33 |
| gema | no | 10:33 |
| cjwatson | Not sure then :-( | 10:34 |
| cjwatson | You could attach gdb without crashing the process | 10:34 |
| cjwatson | 'gdb /usr/bin/python process-id-of-ubiquity' | 10:34 |
| cjwatson | maybe sudo | 10:34 |
| davmor2 | cjwatson, gema: is it stopping once you click on the continue button post user details? | 10:34 |
| gema | we already attached it, got thread info and stack trace of the relevant thread | 10:34 |
| gema | however without symbols that's not all that helpful | 10:34 |
| gema | so we are trying to get a core dump to debug it on a machine with the symbols | 10:35 |
| gema | davmor2: yes | 10:35 |
| cjwatson | Or you could grab the symbols from ddebs.ubuntu.com first | 10:35 |
| cjwatson | And install them in the live session | 10:35 |
| cjwatson | That would be my approach | 10:35 |
| gema | cjwatson: ack | 10:36 |
| davmor2 | gema: I got it here I worked through all the files I could with evan and we couldn't find anything useful either | 10:36 |
| gema | davmor2: the camera setup is failing | 10:36 |
| gema | davmor2: we are trying to get some debuggable stuff out of it | 10:36 |
| gema | davmor2: we've narrowed it down to ubiquity_webcam_play with gdb | 10:37 |
| cjwatson | That function itself, or the gst stuff it calls? | 10:37 |
| cjwatson | That function is really very simple indeed | 10:37 |
| cjwatson | void | 10:38 |
| cjwatson | ubiquity_webcam_play (UbiquityWebcam *webcam) { | 10:38 |
| cjwatson | UbiquityWebcamPrivate *priv = UBIQUITY_WEBCAM_PRIVATE (webcam); | 10:38 |
| gema | cjwatson: the gst stuff, would be our guess | 10:38 |
| cjwatson | if (gst_element_set_state (priv->camerabin, GST_STATE_PLAYING) == GST_STATE_CHANGE_FAILURE) { | 10:38 |
| cjwatson | g_print ("setting camerabin to PLAYING failed\n"); | 10:38 |
| cjwatson | return; | 10:38 |
| cjwatson | } | 10:38 |
| cjwatson | } | 10:38 |
| davmor2 | gema: yeah that's what I had a chat with ev about while I was down in millbank | 10:39 |
| CIA-32 | ubiquity: cjwatson * r5343 trunk/ (debian/changelog src/webcam/webcam.c): | 10:41 |

| cjwatson | ^- I don't *think* that's your bug but I happened to notice it | 10:41 |
| gema | ours gets stuck there forever, until it runs out of memory | 10:42 |
| cjwatson | do you have any of the backtrace at all? | 10:51 |
| cjwatson | even without symbols it might be worth a brief look | 10:51 |
| gema | cjwatson: I attached all the info I could gather, one file has most symbols loaded, bug 966294 | 11:33 |
| ubot2 | Launchpad bug 966294 in ubiquity "Ubiquity loops forever from ubiquity_webcam_play" [Undecided,New] https://launchpad.net/bugs/966294 | 11:33 |
| gema | cjwatson: hope it helps, because it was a painful process :) | 11:33 |
| cjwatson | Do you still have that gdb running? | 11:35 |
| gema | cjwatson: yes | 11:35 |
| cjwatson | Could you go up to frame 35 (ubiquity_webcam_play), then 'p priv' and 'p priv->camerabin'? | 11:36 |
| gema | priv is optimized out | 11:36 |
| cjwatson | Oh, hah, that's at the bottom | 11:36 |
| cjwatson | OK, not NULL at least | 11:36 |
| gema | that's the closest we could get | 11:36 |
| cjwatson | That's an odd place to hang. Does it sit there? | 11:37 |
| cjwatson | Oh, I suppose if it's copying something unbounded. | 11:37 |
| gema | it just keeps going until it runs out of memory at some point, the UI unresponsive | 11:37 |
| cjwatson | It smells of a non-NULL-terminated list or something. | 11:42 |
| cjwatson | This will probably take ages to run, and I'm not entirely certain it won't break something else, but could you try running ubiquity under 'valgrind --log-file=ubiquity.vg --error-limit=no --num-callers=50'? | 11:47 |
| cjwatson | I can try zenning it from the code in parallel, but that's a rather uncertain process. | 11:48 |
| cjwatson | Wonder if there's any hope of reproducing this in the test suite | 11:58 |
| cjwatson | Hm, valgrind doesn't seem to have a problem with this in the test suite for me. | 12:16 |
| gema | cjwatson: I was cooking, reading you now | 12:26 |
| gema | cjwatson: running, it is taking a while, though | 12:50 |
| gema | cjwatson: with trace-children, valgrind exits before ubiquity actually starts and without trace-children it doesn't trace the right process | 13:20 |
| gema | cjwatson: not sure what else to do, I could ship the netbook to you, for debugging purposes? | 13:21 |
| cjwatson | See previous comments about lack of space | 13:22 |
| gema | cjwatson: you can return it to me when you are done! | 13:22 |
| cjwatson | Hmm | 13:22 |
| gema | cjwatson: it is a small pink testing netbook | 13:22 |
| cjwatson | Well, there's that. Dunno. I guess maybe, if it won't leave you short. Will you be at the release sprint? | 13:23 |
| cjwatson | (It'd be too late to fix it then, but I could return it then, as an option.) | 13:23 |
| gema | cjwatson: I wasn't planning to be, but I can come if necessary, if it is only for returning it, you can give it to michelle and she'll send it to me | 13:23 |
| cjwatson | I think I should see if it reproduces on my own laptop first, though I really ought to write my performance review before rebooting for that :-) | 13:26 |
| gema | cjwatson: ack, I am trying something else with jibel meanwhile | 13:26 |
| gema | cjwatson: we can arrange for this after beta anyway | 13:26 |
| gema | davmor2: you said you were discussing this ubiquity hang problem with ev back in london | 14:39 |
| gema | davmor2: can you check with camera do you have? | 14:39 |
| davmor2 | gema: http://davmor2.co.uk/pc-specs/main-laptop.html | 14:44 |
