| geofft | Someone mentioned at UDS there's a way to tag patches as forwarded (or not or notneeded) to Debian, separately from forwarded upstream. I don't see this immediately in the packaging guide or in DEP-3, what's the syntax? | 00:37 |
| tumbleweed | geofft: Bug-Debian: ... | 00:38 |
| geofft | I see the Bug-Debian etc. field. I guess that's usable for the same thing | 00:38 |
| tumbleweed | the debian bug is the appropriate place to forward the patch, so if you are mentioning the bug, you shuold forward the patch there too. | 00:39 |
| geofft | Hrm. I would have interpreted Bug-Debian as "this fixes this Debian bug", not as "the pull request for this patch is this Debian bug", but there's not a huge difference | 00:39 |
| tumbleweed | Debian doesn't have pull requests | 00:40 |
| geofft | i.e. if you have a wishlist feature request that doesn't solve an existing bug. I guess you should go file a wishlist bug, yeah | 00:40 |
| tumbleweed | (unless the packaging is in a non-alioth-hosted VCS somewhere that does) | 00:40 |
| geofft | The one thing that Bug-Debian doesn't provide is a "not needed" option | 00:40 |
| tumbleweed | then you are going to mention that it's ubuntu-specific in the Description and have a Fowarded: not-needed, anyway | 00:41 |
| tumbleweed | the way you forward a patch to debian is by opening a bug, with a patch... | 00:41 |
| geofft | oh, and I see that the implicit value for Forwarded is conditional on the Bug field. | 00:41 |
| geofft | okay, I can see that way of thinking | 00:42 |
| geofft | well, you could have Ubuntu-specific patches that should get forwarded upstream, e.g. if Ubuntu has some random person's patchset and Debian doesn't | 00:42 |
| tumbleweed | fair enough, but that's non-ideal in the first place :) | 00:43 |
| geofft | first example that comes to mind is a patch to overlayfs; Debian doesn't need it forwarded but upstream does | 00:43 |
| geofft | (the kernel is special, admittedly, but you can imagine it happening elsewhere) | 00:43 |
| infinity | If it's suitable for upstream, it's suitable for Debian (except in the case of software that just isn't *in* Debian, which renders the above conversation moot). | 00:44 |
| infinity | If it's not suitable for other downstreams, it's not suitable for upstream. | 00:44 |
| geofft | I think the other suboptimality might be that you could use Bug-Debian to say "this fixes this Debian bug, but I didn't actually make a comment on the Debian bug saying as much" | 00:45 |
| geofft | but then you're just being a jerk. | 00:45 |
| broder | we mostly enforce that socially | 00:47 |
| geofft | yeah, fair enough, I'm convinced that Bug-Debian is what I actually care about and the exceptions are sufficiently rare | 00:49 |

| cjwatson | Ye | 03:08 |
| cjwatson | s | 03:08 |
| cjwatson | And other such things; ultimately it should let us get rid of the hardcoding of ubuntu-security in LP | 03:09 |
| cjwatson | Though that requires a bit more considerably more complicated work | 03:09 |
| cjwatson | Anyway, the DB column is the same for upload and queue admin, I just didn't want to try to do both in the same branch | 03:10 |
| psusi | cjwatson, is there *any* part of ubuntu you don't work on? ;) | 03:16 |
| superm1 | siretart: oh i must have missed that further in the log, i'll re-read the rest. as for the internal copy of ffmpeg, they have some code they have forked for now that their delta doesn't make sense upstream but they need internally when used with DVB of sorts | 04:08 |
| superm1 | so while it is possible to link to a system ffmpeg it will certainly break | 04:08 |

| janimo | cjwatson, hi, is there a clean way in grub-mkconfig snippets to modify an existing line in an already generated part of the config file - to remove a boot cmdline argument to be precise? | 07:42 |
| janimo | to be even more precise the vthandoff=7 part should be deactivated in a custom build and currently a grub-mkconfig hook is sedding the grub.cfg.new file but that does not always work | 07:44 |

| * apw just did an install and at the end it says 'downloading langpacks' and later 'installing langpacks' but if i look its actually also installing libreoffice en-toto, is that expected | 10:53 | |
| cjwatson | apw: suspect you might find that's an upgrade | 11:04 |
| cjwatson | janimo: in general, no - the text has already been generated but there's no guarantee that it's been flushed | 11:05 |
| cjwatson | janimo: if you don't mind changing gfxpayload as well, you could just emit 'set linux_gfx_mode=text' perhaps | 11:06 |
| cjwatson | jquery-ui-themes wins the prize for today's silliest binary package names. | 11:14 |
| cjwatson | I: jquery-ui-themes -> libjs-jquery-ui-theme-hot-sneaks_1.8.18+dfsg-1. | 11:14 |
| cjwatson | I: jquery-ui-themes -> libjs-jquery-ui-theme-le-frog_1.8.18+dfsg-1. | 11:14 |
| cjwatson | I: jquery-ui-themes -> libjs-jquery-ui-theme-swanky-purse_1.8.18+dfsg-1. | 11:14 |
| janimo | cjwatson, would set linux_gfx_mode=text imply a non-graphics splash? | 11:23 |
| cjwatson | janimo: No, just a text-mode handover from GRUB to the kernel | 11:30 |
| janimo | cjwatson, would this make the change to vthandoff unnecessary? | 11:33 |
| janimo | I think the issue with vthandoff was it caused black screen with a poulsbo-like driver | 11:33 |
| janimo | tseliot, ^ ? | 11:33 |
| cjwatson | janimo: 'set linux_gfx_mode=text' has two effects: it causes 'set gfxpayload=text' rather than 'set gfxpayload=keep', and it drops vt.handoff=7 | 11:35 |

| tseliot | janimo, cjwatson: it's the gfxpayload=text part that I'm trying to avoid | 12:40 |
| cjwatson | tseliot: so just emitting 'set linux_gfx_mode=text' is probably what you want to do | 12:44 |
| tseliot | cjwatson: well I would need 'set linux_gfx_mode=keep' but how would you suggest that I do it? | 12:47 |
| cjwatson | Oh, sorry, misunderstood | 12:48 |
| cjwatson | =keep will leave you with vt.handoff=7 by default | 12:48 |
| cjwatson | I assume you're trying really really hard to avoid modifying /etc/grub.d/10_linux directly, since that's easier than this hackery | 12:49 |
| cjwatson | But you *could* perhaps redefine the gfxmode function in a later grub-mkconfig hook | 12:49 |
| janimo | yes, probably that's the easiest | 12:49 |
| cjwatson | To just something like | 12:49 |
| cjwatson | function gfxmode { | 12:49 |
| cjwatson | set gfxpayload="$1" | 12:49 |
| cjwatson | } | 12:49 |
| cjwatson | pitti: Am I right in thinking that ~lp_queue/manual-queue/ was only ever used for langpack uploads, and that we no longer do them that way? | 12:50 |

| tseliot | cjwatson: where would I call that function from? | 13:20 |
| tseliot | gfxmode | 13:20 |
| cjwatson | tseliot: You don't need to, the fragments generated by 10_linux do so | 13:23 |
| tseliot | cjwatson: but wouldn't I still get vt.handoff=7 this way? | 13:24 |
| cjwatson | tseliot: Not if you redefined gfxmode to not set vt_handoff to anything | 13:25 |
| tseliot | cjwatson: ok, I get it now. Thanks | 13:26 |
| janimo | cjwatson, but redefine it in a hook prior to 10_linux so it takes precendence? | 13:28 |

| slangasek | cjwatson: would it be more straightforward to move merges to the cloud somehow? | 14:21 |
| xnox | slangasek: we need persistent storage for the results, but the cloud can do the merge attempts. | 14:22 |
| slangasek | right | 14:22 |
| * xnox cloud tends to have holes in the floor, which make valuable files drop off the cloud. | 14:24 | |
| mdeslaur | slangasek, cjwatson: merges needs to be a trusted machine, since some people rely on the tarball that is generated. Else, we need to throw the tarball away and just keep the report. | 14:24 |
| slangasek | mdeslaur: I didn't mean /that/ cloud ;) | 14:25 |
| xnox | if rossetta is emailing me about errors in translation templates from a recent package I uploaded.... do i have to deal with them? | 14:26 |
| slangasek | xnox: generally no - they're usually upstream issues that you don't need to do anything about | 14:26 |
| mdeslaur | slangasek: just making sure :) | 14:26 |
| slangasek | xnox: if you *touched* the translations and are now getting errors, you should worry about it :) | 14:27 |
| cjwatson | geser: good idea; done | 14:28 |
| xnox | slangasek: On 2012-05-17 07:33z (2 hours 55 minutes ago), you uploaded a file with | 14:29 |
| xnox | Catalan (ca) translations for grub in Ubuntu Precise package "grub2" to | 14:29 |
| xnox | Launchpad | 14:29 |
| Laney | Does mom download all sources from D + U? | 14:29 |
| cjwatson | slangasek: the main difficulty, aside from sheer awkward size, is that merges needs to keep a lot of source packages around which are no longer in any current archive to serve as base revisions; not to mention archived patches and the like | 14:29 |
| * xnox somehow thinks catalan speaking users just might use sudo over the next 5 years. | 14:29 | |
| cjwatson | xnox: I think that one is ignorable | 14:29 |
| slangasek | xnox: yeah... maybe that's cjwatson's problem? :) (grub2) | 14:29 |
| slangasek | cjwatson: right | 14:29 |
| cjwatson | there are a few things that Rosetta more or less legitimately whines about that I haven't bothered fixing because it involves liaising with upstream translators and it didn't look that important; and I think possibly also some cases where it was just being pedantic | 14:30 |
| * xnox notes down "if in daubt, `maybe that's cjwatson's problem?`" | 14:30 | |
| cjwatson | Laney: only given series in each, but yes | 14:30 |
| cjwatson | xnox: ... | 14:31 |
| * xnox rips the paper apart. | 14:31 | |
| * Laney saw something about block storage somewhere … | 14:31 | |
| cjwatson | yeah, it might be doable now that canonistack does block storage, but I'm not about to move an important production service to it until others have shaken out the bugs first :) | 14:32 |
| * slangasek nods :) | 14:32 | |
| Laney | I was thinking as an interim until the hardware is acquired | 14:32 |
| xnox | msgfmt didn't give any error... | 14:33 |
| cjwatson | Laney: given its apparent I/O problems, I'm not sure I could transfer the current state to the cloud without IS help anyway | 14:33 |
| * xnox is ignoring that translation file | 14:33 | |
| cjwatson | MoM isn't desperately cloudy right now; it could be, but if it were actually going to take advantage of the cloud properly it would need to be refactored rather a lot | 14:33 |
| cjwatson | not to say that wouldn't be a good idea | 14:33 |
| Laney | cjwatson: Can it not recreate its own state? Or do you think that would be too network heavy? | 14:34 |
| * Laney would be willing to give the current code a spin | 14:34 | |
| cjwatson | It needs to have its pool available for base revisions | 14:34 |
| cjwatson | In general it cannot recreate its own state entirely from scratch | 14:35 |
| Laney | ah, so it can't use snapshots / LP to download old stuff | 14:35 |
| Bluefoxicy | so I was thinking about hibernation | 14:35 |
| Bluefoxicy | I'm not sure how the kernel does it. :| | 14:35 |
| cjwatson | Not at the moment, and it's possible not everything is available on either; I've certainly seen cases in the past where casey was the only thing I could find that had managed to retain something | 14:35 |
| Laney | I can believe that it wouldn't get 100% coverage | 14:36 |
| cjwatson | I don't know exactly what the problem is, but doing a full run causes it to reboot, so I have no confidence that I could rsync off the data; but I gather the problem is more likely to be RAM or RAID controller or something, not the disks themselves | 14:36 |
| cjwatson | So I'd rather wait for IS and continue to hassle them :) | 14:36 |
| Bluefoxicy | for a rough outline my thinking is: 1) Prepare the system (flush all buffers, finish fetching I/O from hardware, etc); 2) Stop scheduling all user applications; 3) Flush all buffers and page cache; 4) Remount read-only everything except the target for /hiberfile; 5) Flush all application RAM to /hiberfile (through LZO or LZ4); 6) extend /hiberfile to hold kernel RAM; 7) RO-mount the file system; 8) Flush kernel memory to /hiberfile | 14:38 |
| Bluefoxicy | that's probably completely different from what the kernel actually does :| | 14:39 |
| Bluefoxicy | although I think being able to flush to a dynamically created hibernation file and (OPTIONALLY--good for 32GB RAM and slow hard disk, not so good for SSD or SCSI-RAID etc) compressing the data as it's written out would be useful | 14:40 |
| * Bluefoxicy rambles about nothing interesting | 14:40 | |
| xnox | Bluefoxicy: what are you trying to achive? | 14:41 |
| Bluefoxicy | xnox: I think it'd be nice to be able to hibernate without a swap partition, or with a swap partition that currently has too much swapped onto it to take on all of RAM | 14:41 |
| highvoltage | uwin 41 | 14:42 |
| Bluefoxicy | xnox: This is already possible--you can hibernate to a swap file; but more interesting would be swapping to a dynamically created file (i.e. not a swap file), and the potential applications for compressing the hibernation file may be interesting (compression may be slower than just writing to disk; then again disk may be too small to hold 5-10 gigs of hibernation data) | 14:43 |
| Bluefoxicy | I think on MY system compressing would be slower than writing straight, because I have an SSD with a SandForce chipset that compresses data on-the-fly to improve throughput anyway--compressing stuff before writing it to disk actually slows my disk access | 14:44 |
| xnox | Bluefoxicy: i always have swap as twice my RAM, exactly because of failing to swap. Usual and rude answer is "you should be using LVM and just extend your swap partition". | 14:44 |
| xnox | I don't have fancy drives. | 14:44 |
| xnox | I do have full disk encryption with LUKS | 14:44 |
| xnox | good luck, sounds like a reasonable cause. | 14:44 |
| Bluefoxicy | xnox: I just use zram | 14:44 |
| Bluefoxicy | (by the way, don't ever load the zcache module: it doesn't actually do anything--as I understand it should work compiled it, but does not work as a module--and it completely destroys the kernel's ability to manage page cache) | 14:45 |
| xnox | nice ! =) | 14:46 |
| * xnox goes to blog 'how to load zcache module to make your ubuntu run faster' | 14:46 | |

| xnox | maybe i should read -discuss.... | 14:47 |
| Bluefoxicy | seriously, when I had zcache loaded my kernel kept purging cache down to like 150MB and then struggling with all the extra disk access, with a gig of free RAM sitting around :P | 14:47 |

| mdz | cjwatson, the fridge calendar disagrees with the email :-/ | 16:45 |
| cjwatson | is that a WoW reference? in that case, not to mention that ~nobody had heard of Sardra when casper was written | 16:45 |
| cjwatson | mdz: imagine my surprise | 16:45 |
| Bluefoxicy | cjwatson: 8 bit theater, a running gag is that a certain small boy is repeatedly subjected to horrible, horrible things as consequence of everything the main characters do | 16:46 |
| mdz | perhaps the CC meeting would be a good place to propose abolishing all forms of scheduling except one | 16:46 |

| mdeslaur | micahg: oh, is that one of the syncs? no idea | 16:48 |
| * broder perks up at mention of lintian | 16:48 | |
| micahg | mdeslaur: umm, it didn't build :) | 16:48 |
| mdeslaur | micahg: oh well | 16:48 |
| infinity | micahg: Did you happen to retry it already? | 16:48 |
| micahg | infinity: failed locally as well :) | 16:49 |
| infinity | micahg: Same ENOSPC failures? | 16:49 |
| infinity | Oh, wait. | 16:49 |
| infinity | *cough* | 16:49 |
| mdeslaur | micahg: would be nice if we'd get build failure emails | 16:49 |
| micahg | mdeslaur: there's a bug for that (syncs don't send build failure e-mails) | 16:50 |
| mdeslaur | micahg: how's it failing? | 16:50 |
| micahg | Bug #902114 | 16:51 |
| ubottu | Launchpad bug 902114 in Launchpad itself "When sponsoring using copyPackage, the sponsored person is not sent email from Soyuz" [Low,Triaged] https://launchpad.net/bugs/902114 | 16:51 |
| micahg | mdeslaur: one of the tests is failing | 16:52 |
| Laney | I think you mean bug #862251 | 16:52 |
| ubottu | Launchpad bug 862251 in Launchpad itself "Sync requester doesn't receive build failure emails" [High,Triaged] https://launchpad.net/bugs/862251 | 16:52 |
| mdeslaur | micahg: that bug is for the sponsored person to get the email | 16:52 |
| infinity | Actually looked more like fakeroot failing. | 16:53 |
| * infinity waits for it to fail again. | 16:53 | |
| Laney | does the sponsor get the FTBFS mail for normal uploads? | 16:53 |
| micahg | Laney: yes, that's the bug I was looking for | 16:53 |
| micahg | infinity: yeah, I think you're right | 16:53 |
| micahg | mdeslaur: just a reminder to test build before sponsoring :) | 16:56 |
| mdeslaur | micahg: yeah, I'll definitely keep away from sponsoring next time :) | 16:56 |
| infinity | Actually, there are a ton of failures in the test suite... | 16:57 |
| infinity | *sigh* | 16:57 |
| micahg | this seems to be a common recurrence with lintian every release | 16:57 |
| infinity | Well, if I'm reading the changelog correctly, this one might have dropped Ubuntu support and forced us to modify it anyway, unless the maintainer was kind enough to include an Ubuntu-specific DB for his new generic derivatives handling. | 16:58 |
| * infinity hasn't grabbed the source yet to see. | 16:59 | |
| broder | wait, huh? | 16:59 |
| broder | the stuff niels did was ubuntu friendly | 16:59 |
| mdeslaur | micahg, infinity: sorry about that, I didn't usually test build syncs before, but I'll be more careful | 16:59 |
| broder | (i.e. the purpose of that code was so that we no longer threw tags about original-maintainer) | 16:59 |
| infinity | + [NT] Remove Ubuntu specific handling of distribution names. | 17:00 |
| infinity | Instead replace it with a more generalized one that derivatives | 17:00 |
| infinity | can reuse by extending vendor specific data files. | 17:00 |
| broder | right | 17:00 |
| broder | and the data files are in there | 17:00 |
| infinity | broder: I'm not implying that those changes are unfriendly, just that they require ubuntu-specific files to be there, and I didn't check to see if they are, or if we're expected to tack them on. | 17:00 |
| broder | lintian.uw.o is currently running with something ~2 commits older than the release | 17:00 |
| infinity | broder: Ahh, kay. | 17:00 |
| broder | so lintian itself works, even if the test suite doesnt' | 17:00 |
| infinity | The hardening failures in the testsuite seem pretty obvious (the baseline expectation is just plain wrong for Ubuntu compilers). | 17:01 |
| infinity | Other failures looked a bit more confusing. | 17:01 |
| broder | can you pastebin a log? | 17:01 |
| infinity | The build's still running. | 17:01 |
| infinity | When it's done, it'll be in the "pastebin" called the "launchpad librarian", referenced from https://launchpad.net/ubuntu/+source/lintian/2.5.7/+build/3493637 :P | 17:02 |
| broder | heh | 17:02 |
| micahg | mdeslaur: thanks, at this point of the cycle, I think it's more about encouraging good practices than the actual failure as we'd probably have gotten it next week some time | 17:03 |
| cjwatson | mdz: well, now I'm completely confused, since there's been no activity in -meeting either at the fridge time (which also == the usual obvious UK DST misinterpretation of the mail) or the mailed time | 17:06 |
| mdeslaur | micahg: I didn't think building locally when syncing was a good practice. Would help if this was documented somewhere. | 17:06 |
| mdz | cjwatson, indeed. I just sent an email | 17:06 |
| mdz | I wonder if they were expecting a response and canceled it when they didn't receive one | 17:07 |
| micahg | mdeslaur: hmm, okay, /me wonders where syncing is documented at this point | 17:07 |
| cjwatson | SyncingAndMerging hopefully | 17:07 |
| cjwatson | Hm, maybe not, memory like a thing with holes in | 17:08 |
| Bluefoxicy | mkfs.ext2 is valid from casper? | 17:09 |
| Bluefoxicy | or is that not in $PATH at that time? | 17:09 |
| melodie | hi | 17:15 |
| mdeslaur | micahg: ah, here's the docs: https://wiki.ubuntu.com/SyncRequestProcess | 17:18 |
| zul | Can an archive admin review python-jsonschema please? | 17:18 |
| mdeslaur | micahg: I'll add info about a local build to the wiki | 17:18 |
| micahg | mdeslaur: it's already implied, but a test build of some sort should really be done, thanks | 17:19 |
| mdeslaur | micahg: implied by what? | 17:19 |
| * micahg is reluctant to say required and isn't sure why | 17:19 | |
| micahg | Sometimes the sponsor requires a build log of the Debian package compiled in the Ubuntu release as proof that the new Debian version still compiles in Ubuntu. | 17:19 |
| micahg | that implies a requirement of still building in ubuntu to be sync'd | 17:20 |
| cjwatson | Bluefoxicy: easy test: boot with break=casper-bottom, and you get a shell so you can look | 17:20 |
| * Laney thought it was accepted best practice to test build all uploads (sponsored or not) | 17:20 | |
| Bluefoxicy | cjwatson: nice | 17:20 |
| mdeslaur | Laney: well, I do test build uploads, but I wasn't test building syncs | 17:20 |
| micahg | Laney: only for certain people :) | 17:20 |
| Laney | not all people follow best practice :P | 17:21 |
| micahg | true | 17:21 |
| * infinity admits that he doesn't always test-build syncs, but does watch to make sure they don't fail. | 17:21 | |
| geser | mdeslaur: any special reason for this? as syncs are similar to uploads | 17:21 |
| Bluefoxicy | http://pastebin.com/dfabCsAU | 17:21 |
| broder | man, i had forgotten how intense the lintian test suite is | 17:22 |
| Bluefoxicy | cjwatson: any way I can break into the shell BEFORE casper is executed so I can replace the script and see what happens? | 17:22 |
| mdeslaur | geser: no special reason, it just didn't occur to me that syncs were supposed to be handled differently than autosyncs | 17:22 |
| Bluefoxicy | or do I need to build a livecd and boot it in VirtualBox to find out? | 17:22 |
| Laney | my, Lintian's test suite takes rather a long time to ru | 17:23 |
| Laney | n | 17:23 |
| Bluefoxicy | (the diff above is my first, untested attempt to tell casper to use a zram device instead of tmpfs for the /cow and copy-to-RAM, with ext2 being the filesystem of choice) | 17:23 |
| Bluefoxicy | (the advantage is that these are compressed and so take up less RAM) | 17:24 |
| geser | mdeslaur: for me syncs are a special kind of uploading, so I test-build them like I do before uploading a package | 17:24 |
| mdeslaur | geser: yes, I agree I should have been doing that, and will from now on...It just didn't occur to me before | 17:25 |
| cjwatson | Bluefoxicy: you could just zcat | cpio -it the initrd and see what it contains | 17:27 |
| cjwatson | Bluefoxicy: oh, misread - you can break=mount IIRC | 17:27 |
| * micahg hugs mdeslaur | 17:27 | |
| cjwatson | yeah | 17:28 |
| cjwatson | though you don't have many tools, so sometimes rebuilding is easier | 17:28 |
| * mdeslaur hugs micahg back | 17:28 | |
| Bluefoxicy | hahavvv | 17:29 |
| Bluefoxicy | there's no editor | 17:29 |
| Bluefoxicy | well that's not a problem | 17:30 |

| infinity | micahg, broder: Alright, lintian failed again on the buildds, this time without crazy fakeroot issues (that must have been some other transient oddity). | 17:32 |
| mdeslaur | infinity, broder: is one of you already taking a look, or shall I poke at it? | 17:35 |
| broder | i am not currently taking a look | 17:36 |
| cjwatson | Bluefoxicy: there is sed, which is occasionally useful with a bit of creativity; but yeah, no full-screen editor | 17:36 |
| broder | i can take a look later if you'd like | 17:36 |
| infinity | mdeslaur: I was just rebuilding to see if a previous issue was reproducible, I'll leave it to you to fix the current issues. :P | 17:36 |
| micahg | mdeslaur: I'd suggest pushing back on AnAnt to look at it | 17:36 |
| broder | might be worth pinging nthykier in #debian-qa on oftc to see if he can hel[p | 17:36 |
| infinity | (The hardening failures are obvious, some of the others look slightly less obvious at first glance) | 17:37 |
| mdeslaur | yeah, I'm trying to figure out the apache2-modules failure | 17:37 |
| mdeslaur | hah, lintian is FTBFS on debian too | 17:40 |
| mdeslaur | http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=673198 | 17:40 |
| ubottu | Debian bug 673198 in lintian "lintian: The 2.5.7 source package is missing files (causing FTBFS)" [Serious,Open] | 17:40 |
| xnox | stgraber: http://debblog.philkern.de/2012/05/lazyweb-question-how-to-avoid-leaking.html lxc ? | 17:40 |
| debfx | mdeslaur: <nthykier> Alternatively touch t/tests/apache2-modules-general/skip will make Lintian skip the test, which should be fine until the next upload | 17:40 |
| infinity | mdeslaur: Oh, that's comforting. One more reason why Debian needs to switch to source uploads. | 17:41 |
| mdeslaur | debfx: awesome, thanks | 17:41 |
| micahg | that's the problem with Debian and arch:all packages, no clean build env | 17:41 |
| infinity | micahg: Yeah, see, speaking of people's "best practices" for syncs above, one of the first things I do is check buildd.debian.org logs. Which is useless for arch:all. | 17:42 |
| micahg | infinity: yeah, I like to do that as well | 17:42 |
| micahg | helps on non-x86 archs | 17:44 |
| stgraber | xnox: yeah, something like http://www.stgraber.org/2010/12/12/having-fun-with-containers/ (back when arkose was called sandbox). The only issue is that it needs root privileges... | 17:45 |
| stgraber | xnox: you could also do something similar by directly using lxc-unshare -s PID <cmd> | 17:45 |
| stgraber | xnox: but that'll all be a lot more secure once we have the user namespace in the kernel and these no longer require root access | 17:45 |
| geser | just to realise that the build log for the arch you're interesting it doesn't exist because that's the arch the DD uploaded | 17:47 |
| cjwatson | I vaguely recall hearing once that there was an interface whereby a DD could post their own build log, but of course hardly anyone does | 17:49 |
| infinity | Yes, it's a tricky and high tech interface called "email". | 17:49 |
| infinity | Though, it's been so long since I was a buildd admin, I now forget where the emails get sent. :P | 17:50 |
| cjwatson | Yeah, I also find that I just send e-mails addressed to Santa Claus and they get where I meant them to go | 17:51 |

| * Bluefoxicy fixes a few bugs. | 18:01 | |
| Bluefoxicy | well it ALMOST worked (besides that I had to cp mkfs.ext2 out of the squashfs) | 18:02 |
| Bluefoxicy | it's notably possible to mount the squashfs early and run /filesystem.squashfs/sbin/mkfs.ext2 ... all the libraries it needs are in /lib on the initrd | 18:02 |
| cjwatson | still best to use LD_LIBRARY_PATH when running binaries from a different fs | 18:02 |
| cjwatson | even if it happens to work at the moment - we learned that lesson in d-i a while bac | 18:03 |
| cjwatson | k | 18:03 |
| mdeslaur | not to self: never touch lintian again | 18:06 |
| Bluefoxicy | cjwatson: i think it doesn't matter anyway ... tmpfs swaps, this is silly. Just using zram as swap would accomplish the same goal methinks | 18:12 |
| barry | cjwatson: maybe the work items got out of sync in our browsers? | 18:12 |
| barry | cjwatson: thanks for the email | 18:13 |
| Bluefoxicy | i installed chromium, brought the universe repository down ... there's about 400MB in /cow now and it's taking up 66% of its original size (the actual file data takes up 56%) | 18:13 |
| Bluefoxicy | so this isn't great anyway | 18:13 |

| bryceh | stgraber, yeah https://code.launchpad.net/~jeffreytremaine/ubuntu/precise/balazarbrothers/fix-829819/+merge/106110 needs off the queue; already got taken by debian and we'll just sync it in (just a typo fix) | 19:01 |
| bryceh | stgraber, thanks | 19:01 |

| infinity | Laney: If... Err, what vorlon said. :P | 20:46 |
| infinity | If emacs23-non-dfsg really is just the same stuff that we're adding back in our diff, that seems like a silly amount of effort for us. | 20:47 |
| slangasek | the only binary package it builds is emacs23-common-non-dfsg... should that be a dependency of emacs? | 20:47 |
| slangasek | honestly, either way, I think that may be the simpler route | 20:48 |
| slangasek | i.e. I don't see any barrier to having it in main if that's where it belongs | 20:48 |
| slangasek | in fact since it's just a binary package split, it shouldn't need a MIR | 20:48 |
| Laney | if we're OK having it in main as a Depends, that should get us to ~ where we are now | 20:48 |
| Laney | and let us drop a bunch of delta | 20:48 |

| slangasek | Laney: I'm in favor of just making it a binary dep from emacs23 and avoiding the horror deltas :) | 20:50 |
| slangasek | rather, from emacs23-common | 20:50 |
| Laney | rock | 20:50 |
| Laney | deleted debian/patches/ubuntu-restore-nondfsg-files.diff | 20:51 |
| rbasak | There's a tool to filter various apt list type files, but I can't remember what it's called and I can't find it. I think it's named after grep. Does anyone know what I'm talkinga bout? | 21:00 |
| Laney | Probably grep-dctrl | 21:01 |
| rbasak | that's it - thanks|! | 21:03 |
| bryceh | Laney, do you want to shoot me another .debdiff for whatever remains? | 21:05 |
| Laney | bryceh: yeah, 5 mins | 21:05 |
| bryceh | Laney, great, thanks | 21:05 |
| Laney | long emacs build is long | 21:37 |

| bdmurray | If I'm planning on tag a bunch of bugs should I email ubuntu-devel or someone? or just have at it | 21:58 |
| bdmurray | slangasek: what do you think⸮ should I email some group before tagging a ton of bugs in Launchpad | 22:15 |
| Laney | bryceh: http://people.ubuntu.com/~laney/emacs23_23.4+1-3ubuntu1.debdiff | 22:17 |
| Laney | off now, I'll pick up any issues in the morning | 22:18 |
| Laney | o/ | 22:18 |
| bryceh | Laney, thanks cya! | 22:18 |
| bryceh | @pilot out | 22:18 |

| bryceh | bdmurray, 355 dupes against libx11, oh my | 22:25 |
| bdmurray | and the one after that looks similar | 22:26 |
| bryceh | bdmurray, of course the bug won't open now | 22:27 |
| bdmurray | bryceh: use /+text | 22:27 |
| bryceh | yeah I know | 22:27 |
| bdmurray | should write a greasemonkey script to mark up +text | 22:28 |
| bryceh | bdmurray, note that it says it's _asserting_ in libx11. That (usually) means that the client is making x11 calls incorrectly | 22:28 |
| bryceh | heh that'd be awesome | 22:28 |
| bdmurray | right, I think we talked about an update-manager bug too | 22:29 |
| bryceh | yeah so 507062 sounds like it might be a bug in cairo causing it | 22:31 |
| slangasek | bdmurray: hmm, I don't see any need for emailing ubuntu-devel before tagging a batch of bugs. will you be doing the tagging as a bot account? That might be best, so people can filter out that kind of thing | 22:37 |
| bdmurray | slangasek: yes a bot. Right, I'm not sure the email is really necessary either, I just recall doing that years ago. | 22:38 |
| Bluefoxicy | hmm, so here's a good question then | 22:38 |
| slangasek | bdmurray: personally, I wouldn't worry either way | 22:39 |
| slangasek | anyone who has time to worry about mass-tagging clearly has too much time to read bug mail ;) | 22:39 |
| Bluefoxicy | tmpfs gets swapped, so there's no reason to put it on a zram device | 22:39 |
| Bluefoxicy | Making an ext2 on a /dev/zram2 etc does work and will get you compression, but it's pointless | 22:39 |
| Bluefoxicy | But what's the equivalent for block devices? | 22:39 |
| bdmurray | slangasek: and doing it now it will get mixed in with other noise | 22:40 |
| Bluefoxicy | to my knowledge there's no dm-compress, so the prospectus for compressing a COW on a persistent device is minimal | 22:40 |
| psusi | Bluefoxicy, btrfs supports compression... there were some patches for ext compression but they were never merged | 22:53 |
| psusi | Bluefoxicy, it can't be done at the block layer | 22:53 |
| Bluefoxicy | psusi: good point. I'm trying to figure what's good for a persistent root. | 22:53 |
| Bluefoxicy | er, cow | 22:53 |
| psusi | Bluefoxicy, wait, what's your goal? cow or compression? | 22:54 |
| * Bluefoxicy patches casper to mount the cow at /moo instead | 22:54 | |
| Bluefoxicy | psusi: I was just thinking like if you did a persistent root on a USB stick, it'd be huge | 22:54 |
| Bluefoxicy | psusi: especially if you upgraded packages etc | 22:54 |
| melodie | Bluefoxicy, you could remove the packages and the docs once the update done | 22:55 |
| Bluefoxicy | but also if you install to USB, you wind up with a situation where a 700MB CD becomes 2 gigabytes of crap | 22:55 |
| melodie | I have persistant "changes" directory for one distro and I manage it not too bad | 22:56 |
| Bluefoxicy | or... you copy filesystem.squashfs to the USB stick under a partition, use a COW partition | 22:56 |
| Bluefoxicy | melodie: that's true | 22:56 |
| psusi | Bluefoxicy, try installing to btrfs with compression enabled? | 22:56 |
| melodie | I also use this mode to make the changes in the usb stick before installing with the changes to hard drive | 22:56 |
| melodie | Bluefoxicy, and usb sticks tend to be cheaper and cheaper. a 4 gb here now can be found for less than 5 euros. | 22:57 |
| Bluefoxicy | melodie: true as well, but does that have a dual-channel controller and get 60MB/s transfer across the bus? | 22:59 |
| melodie | how can I check it ? | 22:59 |
| Bluefoxicy | mind you my SSD gets about 384MB/s (it's on SATA2) and is capable of about 500MB/s if I get it on a SATA3 controller | 22:59 |
| melodie | SSD is faster than usb 2 right ? | 22:59 |
| Bluefoxicy | hdparm -t I guess | 23:00 |
| Bluefoxicy | SSD is much faster :P | 23:00 |
| Bluefoxicy | so is HDD | 23:00 |
| melodie | what is your goal exactly ? perform a usb install for yourself or add a feature for all in a program ? | 23:00 |
| Bluefoxicy | the other part of this argument is that reading 5MB of compressed libraries and expanding it to 15-25MB is likely faster than reading 25MB outright from a slow USB stick that can get 9MB/s | 23:01 |
| melodie | I am very much interested in persistant modes on usb sticks to tell you all. | 23:01 |
| Bluefoxicy | also I'm just asking questions right now | 23:01 |
| Bluefoxicy | anyway psusi has a point | 23:01 |
| melodie | very probably. | 23:01 |
| Bluefoxicy | btrfs now supports LZ4, which is excellent: unlimited parallel compression/decompression, the algorithm is fast, and it has pretty good compression ratios on par with LZO | 23:02 |
| Bluefoxicy | parallel execution is fantastic with all these 4 core Intel i5 systems and the likely 16-32 core ARM systems we'll see in the future | 23:02 |
| melodie | the interesting part for persistant, apart from the nomadic which is obvious, is the possibility to install a fully up to date and personalized (on the fly) version... at any time after a given distribution version has been made available. | 23:03 |
| melodie | how much data can you put in a 700 MiB compressed iso, if using btrfs with LZ4 ? | 23:05 |
| melodie | Let's say current usual programs, nothing special as sounds and videos. | 23:05 |
| psusi | not as much as you can with squashfs | 23:09 |
| psusi | the problem with compression is that it is always a tradeoff between compression ratio, and random access | 23:09 |
| psusi | the more data you compress at once, the better compression you get, but to access some random data in the middle, you have to decompress the whole block | 23:10 |
| melodie | which in clear means safe access to data ? | 23:10 |
| melodie | or fast access... | 23:10 |
| mdawkins | just means more memory is used to decompress | 23:10 |
| melodie | ok | 23:11 |
| psusi | that and you have to read data you don't necessarily need. | 23:11 |
| melodie | ok. :) | 23:11 |
| psusi | that's why gzip gets better compression that pkzip.... pkzip compresses 32k at a time... but if you want to extrat a file from a .tar.gz that is near the end, you have to spend a long time reading and decompressing the whole thing, but zip can skip to the end and start decompressing there | 23:12 |
| mdawkins | is there any discussion about the unioning fs? | 23:17 |
| melodie | psusi, what you said about squashfs does not concern unionfs right ? I think they are two different things ? (aufs vs unionfs maybe ?) | 23:20 |
| mdawkins | melodie: the unioning fs is what makes the livecd interesting | 23:20 |
| mdawkins | otherwise you cant do much with it except for boot and install | 23:21 |
| psusi | melodie, unionfs just takes two different filesystems ( or more ) and combines them into one... it has nothing to do with compression | 23:21 |
| psusi | aufs is the same thing pretty much | 23:22 |
| mdawkins | i have been playing with overlayfs | 23:22 |
| melodie | which one is used by default at Ubuntu ? | 23:22 |
| mdawkins | i thot they were moving to overlayfs after speaking to dev | 23:23 |
| mdawkins | but that was awhile ago | 23:23 |
| melodie | good night | 23:40 |
