| cjwatson | nice | 10:12 |
| xivulon | cjwatson in /bin/partman I have that PARTMAN_NO_COMMIT=1 | 10:21 |
| xivulon | not sure where that is set, but that makes partman exit, is that normal? | 10:21 |
| xivulon | ps mounting /host probably is orthogonal, was some spurious reboot-makes-it-work thing | 10:22 |
| xivulon | have to go, hope the above helps | 10:23 |
| xivulon | evand ^ | 10:24 |
| cjwatson | sigh, I can't conduct a conversation when people join and quit like that :-/ | 10:25 |
| ogra | cjwatson, i see bug 360925 returning on the imx51 vfat alternate images, intrestingly i can rename the file on the mounted vfat image from d-i's shell | 10:33 |
| ubottu | Launchpad bug 360925 in mobile-meta "md5sum check of UNR image fails in one file" [Undecided,Invalid] https://launchpad.net/bugs/360925 | 10:33 |
| ogra | cjwatson, which makes me think we miss something at image build time here | 10:35 |
| TheMuso | cjwatson: Looks like the hang with formatting filesystems using parted_server is another weird powerpc gcc bug. I am just double checking, but it seems if I build parted_server/partman-base with -O2 for powerpc instead of -Os, thigns work fine. | 10:52 |
| cjwatson | aha | 10:53 |
| cjwatson | I'd never have found that, glad you did | 10:53 |
| cjwatson | happy to change that for post-RC, I think | 10:53 |
| TheMuso | Right. I am checking with a live CD, but want to check with alternates as well. | 10:53 |
| TheMuso | s/alternates/altnerate | 10:53 |
| cjwatson | remind me of the bug number? | 10:54 |
| TheMuso | one sec | 10:54 |
| cjwatson | if you can make sure a gcc bug is filed as well, I'd appreciate it | 10:55 |
| cjwatson | with preprocessed source | 10:55 |
| TheMuso | Ok, against which source gcc package? | 10:55 |
| TheMuso | its bug 450214 | 10:55 |
| ubottu | Launchpad bug 450214 in parted "Parted server appears to hang when attempting to format a swap partition on powerpc." [Undecided,New] https://launchpad.net/bugs/450214 | 10:55 |
| cjwatson | gcc-4.4 | 10:55 |
| TheMuso | Ok./ Whats the easiest way to get pre-processed source? | 10:56 |
| cjwatson | build the package, copy and paste the gcc line that builds the relevant program, delete -c and -o parted_server, add -E | 10:56 |
| cjwatson | the gcc people will need to know where the hang is though ... | 10:57 |
| TheMuso | Ok, will confirm everything, and fix up bugs. Shall I open a task against gcc-4.4 on the same bug, or should I open a fresh bug? | 10:57 |
| cjwatson | so it's just partman-base that needs to be rebuilt, not parted as well? | 10:57 |
| TheMuso | I would think another task is ok | 10:57 |
| cjwatson | opening a task is fine, I think | 10:57 |
| TheMuso | This is what I am checking. I am booting avanilla live CD, copying rebuilt partman-base binaries in, and seeing what happens. | 10:58 |
| cjwatson | it could of course still be a parted_server bug that optimisation changes just happen to trigger | 10:58 |
| TheMuso | Right. | 10:58 |
| CIA-33 | partman-base: cjwatson * r170 ubuntu/ (Makefile debian/changelog): | 10:59 |
| CIA-33 | partman-base: Build with -O2 on powerpc to avoid a suspected toolchain bug | 10:59 |
| CIA-33 | partman-base: (LP: #450214). | 10:59 |
| cjwatson | BTW timer "exceptions" aren't really exceptions, they're just the way parted progress information is propagated up | 10:59 |
| TheMuso | Right | 10:59 |
| TheMuso | Looking at the build logs, libparted is built with -O2 anyway. | 11:08 |
| TheMuso | Ok, with ubiquity/live CD with rebuilt partman-base binaries copied in, -O2 is allowing things to function as normal. I think we can go on this, but I'm going to check with the alternate just to be safe, since libparted is in udeb form and built differently. | 11:13 |
| TheMuso | I think I already mentioned in the bug where the hang occurred. If built with -Os, the hang occurs when calling ped_timer_new from a parted_server function, can't remember which one from the top of my head. | 11:16 |
| cjwatson | ok, won't upload straight away anyway, and I think there may be one more partman-base change we need | 11:25 |
| cjwatson | evand: did you get anywhere with that parted_server syslogging work? | 11:25 |
| TheMuso | Yeah of course. | 11:26 |
| evand | cjwatson: no, I was having some trouble with it and temporarily moved on to other bugs. | 11:26 |
| TheMuso | re not uploading, due to RC and its ports after all. | 11:27 |
| cjwatson | evand: shout if you need a hand ... | 11:28 |
| cjwatson | xivulon: PARTMAN_NO_COMMIT=1 is entirely normal | 11:28 |
| cjwatson | partman is divided into two phases in ubiquity; parted_server stays running between them | 11:29 |
| evand | will do; I'll have another look as soon as I've got these kde issues sorted out | 11:29 |
| cjwatson | evand: I was wondering if there's an outside chance that it's causing occasional wubi hangs, you see | 11:29 |
| evand | ah, noted. Priority bumped. | 11:30 |
| cjwatson | since at least some of those have been in the partman-commit phase too | 11:30 |
| xivulon | well the first stage completes successfully I have no tracback on stage 2 | 11:30 |
| xivulon | will try to get something tonight | 11:31 |
| xivulon | No partman or any other shell script in /lib/partman is called after that as far as I can see | 11:33 |
| ogra | cjwatson, bah, my funny remote install fails in UserSetupApply | 11:36 |
| cjwatson | ogra: you might need to take some care with the user id | 11:37 |
| ogra | well | 11:37 |
| cjwatson | ogra: note that casper is very deliberately created at uid 999 | 11:37 |
| ogra | its not actually a supported way of installation anyway | 11:37 |
| cjwatson | use 998 :) | 11:37 |
| ogra | hmm | 11:37 |
| cjwatson | or actually, why not just set a password for the ubuntu user? | 11:38 |
| cjwatson | and ssh in as that | 11:38 |
| ogra | oh, right | 11:38 |
| * ogra tries that | 11:38 | |
| TheMuso | cjwatson: Ok parted_server manages to format a swap partition, however I think mke2fs is choaking in a similar way to parted_server, which makes me think that, once again, the e2fsprogs udeb is built with -Os for powerpc. | 11:41 |
| TheMuso | this is on the alternate | 11:41 |
| cjwatson | yes, see BF_CCOPTS in e2fsprogs/debian/rules | 11:44 |
| TheMuso | yep just found that myself | 11:47 |
| * TheMuso rebuilds with -O2 to see if there is a difference. | 11:49 | |
| CIA-33 | ubiquity: evand * r3542 ubiquity/ (2 files in 2 dirs): | 12:04 |
| CIA-33 | ubiquity: Properly set the size of the partition to be created upon resizing | 12:04 |
| CIA-33 | ubiquity: in the KDE frontend (LP: #455580). | 12:04 |
| TheMuso | cjwatson: ok rebuilding e2fsckprogs-udeb with -O2 has things working | 12:09 |
| cjwatson | ok, I'll add an e2fsprogs task to that bug | 12:13 |
| TheMuso | Ok. I'll get some pre-processes source for parted_server.c at least. | 12:21 |
| evand | davmor2: updated bug 455653 requesting some details from you. | 12:23 |
| ubottu | Launchpad bug 455653 in ubiquity "kubuntu unable to check format checkboxes in manual partitioning" [High,Incomplete] https://launchpad.net/bugs/455653 | 12:23 |
| davmor2 | evand: both but I'll be running checks on kubuntu shortly so I'll double check on that one for you | 12:24 |
| evand | okay | 12:24 |
| evand | for what it's worth, I cannot reproduce it in 20091019.2 | 12:25 |
| TheMuso | cjwatson: Ok I'll do other alternate tests tomorrow night for a few other common install cases, just to ensure we catch as much as possible. I suspect this happens with anything dealin with disks, so lvm, cryptsetup etc probably need checking. | 12:32 |
| cjwatson | ok, thanks | 12:34 |

| evand | cjwatson: anything else you want to land in trunk before I do an upload? | 14:51 |
| cjwatson | evand: go for it, anything I discover with wubi is going to take a while | 14:54 |
| evand | incidentally, I've run headfirst into the "Try (hd0,0): NTFS5:" issue on the test install I've been running in the background. | 14:55 |
| evand | perhaps I'm forgetting a bit of history, but it seems odd that we set ubiquity/reboot to true in wubi. Of course usability issues are for a different time in the cycle. :) | 14:57 |
| cjwatson | try finding the top-level grub config file in the ntfs filesystem and putting 'set debug=all' at the top of it | 14:57 |
| evand | will do | 14:58 |
| evand | cjwatson: for what it's worth, http://people.canonical.com/~evand/tmp/wubi-failure-2.png | 15:35 |
| ogra | wow, my remote install which i started 6h ago on my babbage board finbally finished ... | 15:49 |
| ogra | package removal did crawl ... took several hours | 15:49 |
| evand | interesting. Wait long enough and it boots, which I think is in line with what davmor2 was experiencing. | 15:53 |
| evand | and it boots fine every time now. argh. | 15:54 |
| CIA-33 | ubiquity: evand * r3545 ubiquity/debian/changelog: releasing version 2.0.2 | 16:25 |
| === bdmurray_ is now known as bdmurray | ||
| davmor2 | evand: we went out for 2 hours the last time I had that issue and it hadn't started how long is a long time? | 16:45 |
| evand | ten minutes or so | 16:46 |
| evand | perhaps it was just a sufficient number of reboots / mounts | 16:46 |
| cjwatson | davmor2: reproduced this under strace, digging ... | 16:46 |
| cjwatson | (not that it's immediately illuminating, but) | 16:47 |
| cjwatson | without a doubt, something else is asynchronously opening stopfifo, and I'm pretty sure it isn't ubiquity | 16:55 |
| cjwatson | my suspicions are drifting back in the direction of sreadahead, so I'm going to give that a try | 16:56 |
| evand | not sure if it's just as a result of me rebooting a third time, but diverting /sbin/readahead fixed the hangs I was getting in partman. | 17:09 |
| cjwatson | it's working well for me, though I removed /etc/init/sreadahead.conf | 17:12 |
| cjwatson | so far, anyway | 17:12 |
| cjwatson | Keybuk's comments on #ubuntu-release filled in the gaps of understanding I had on how sreadahead might be breaking it | 17:13 |
| cjwatson | (you mean /sbin/sreadahead?) | 17:13 |
| evand | err yes | 17:14 |
| * evand reads up | 17:14 | |
| cjwatson | 4/4 successful so far (I rebooted once it got to "Calculating files to skip copying") | 17:15 |
| cjwatson | now to try without strace, which will be faster | 17:16 |
| cjwatson | oh, and FWIW, ghastly rune for arranging to strace both parted_server and partman-commit was to put this in /scripts/casper-bottom/25configure_init in the initrd: | 17:20 |
| cjwatson | sed -i "s/return ('\/bin\/partman-commit'/import subprocess; subprocess.Popen(['strace', '-f', '-o', '\/tmp\/parted_server.trace', '-s', '1024', '-tt', '-p', subprocess.Popen(['pidof', 'parted_server'], stdout=subprocess.PIPE).communicate()[0].strip()]); return (['strace', '-f', '-o', '\/tmp\/partman-commit.trace', '-s', '1024', '-tt', '\/bin\/partman-commit']/" /root/usr/lib/ubiquity/ubiquity/components/partman_commit.py | 17:20 |

| cjwatson | I'll be off IRC for a couple of hours, then probably back later in the evening ('cos my life is so exciting) | 17:38 |
| davmor2 | I don't know what you mean I'll be burning and testing cd's till midnightish | 17:39 |
| cjwatson | hah | 17:40 |
| cjwatson | hopefully this lot will be a bit more rewarding, wubi-wise | 17:40 |
| davmor2 | \o/ | 17:42 |
| cjwatson | and there we go, rebooted fine for me | 17:45 |
| xivulon_ | Hi colin, noticed you fixed 439279 thanks a lot | 21:29 |
| davmor2 | xivulon_: Just got to wait for the iso's to test it out fully now :) | 21:30 |
| xivulon_ | yep! | 21:30 |
| * davmor2 is looking forward to a fully functioning wubi :) | 21:31 | |
| xivulon_ | Well actually I can test now with break=init + sed | 21:31 |
| xivulon_ | I do think I tried to kill sreadahead in the past (as per colin suggestion), hmm | 21:33 |
| xivulon_ | but that was definitely after chroot... | 21:34 |
| davmor2 | xivulon_: yeah so did I but it was also held up by something just before it. | 21:34 |
| davmor2 | xivulon_: cjwatson solved that one and this one was left | 21:35 |
| xivulon_ | ah cool | 21:36 |
| davmor2 | xivulon_: he tried it about 8 times before he had to shoot off. So he is hoping that that it is now :) | 21:38 |
| davmor2 | xivulon_: I think evand had a success doing the same thing too (but I could be wrong) | 21:39 |
| xivulon_ | my karmic kvm jams randomly by the way | 21:48 |
| xivulon_ | sedded 25configure_init, and did a full installation, the installer is way beyond the point where it usually jams | 22:03 |
| xivulon_ | fingers crossed | 22:04 |
| xivulon_ | of course I used break=mount not break=init | 22:08 |
| xivulon_ | :) works here | 22:30 |
| xivulon_ | cjwatson you get a bottle of champagne or a box of coffee at your choice | 22:31 |
| xivulon_ | ^ that is real coffee, not the dark stuff I see you guys drinking... | 22:31 |
| cjwatson | xivulon_: hooray for workingness. I think this was probably the core of the problem all along, but there were some other random problems as well that were masking it | 23:19 |
| xivulon_ | was a close one... fantastic job, as usual | 23:21 |
| xivulon_ | well at least I know a bit more about partman :P | 23:22 |
| cjwatson | hard work tracking it down today, was still a guess in the end | 23:22 |
| cjwatson | couldn't actually catch the whole thing in the act except by stracing the *entire system* somehow ;-) | 23:22 |
| cjwatson | which didn't sound like much fun | 23:22 |
| xivulon_ | guess have to top up my offer | 23:23 |
| cjwatson | hmm, thinking about it I suppose I could have inserted an lsof call into parted_server or similar, but meh | 23:23 |
| cjwatson | meh, it's my job :) | 23:23 |
| cjwatson | will you be at the release party? | 23:23 |
| xivulon_ | most likely yes | 23:23 |
| cjwatson | I think I will be - have to take the dog to be neutered the next morning, but can probably stay for a short while | 23:24 |
| xivulon_ | hope to see you there! | 23:24 |

| davmor2 | this is an install against karmic, I don't know if that is relevant | 23:50 |
| cjwatson | so you did one install on sda1 (/) sda5 (swap), then another install on sda6 (/) sda7 (swap), and only the second showed up in grub.cfg? | 23:51 |
| cjwatson | os-prober found it, at least, I can see that much in the log | 23:51 |
| davmor2 | cjwatson: looks that way yes unless I'm completely mis-reading it | 23:51 |
| cjwatson | I wonder if it then completely failed to parse grub.cfg | 23:52 |

| cjwatson | yeah, can see that in the generated grub.cfg | 23:56 |
