SpamapSfor instance , if I have a maintainer script that stops a service which takes a long time to stop said service, and then tries to stop it again.. it shouldn't fail if the service is already stopped.. but mysql seems to fail this way all the time.00:00

psusistop reading linux tabloids ;)01:40
ebroderWhy is everybody so excited about this patch all of a sudden?01:40
psusibecause Phoronix is hyping it01:41
Sarvatt_(and slashdot)01:41
psusiwith videos of the amayzing difference it makes when you are stupid enough to run make -j6401:41
ebroder(and slashdot)> Ah, that makes sense01:41
psusiyea, that too01:41
ebroderI've never heard of Phoronix and I stopped reading /. about a year ago :)01:41
PiciOnly a year ;)01:42
psusiI've not bothered reading /. in a few years unless I'm board, and I finally checked out phoronix once or twice before this broke because I keep hearing so much about it01:42
ebroderI spent longer thinking about stopping :-P01:42
macophoronix is a benchmarking software maker who uses their software to benchmark OSes and hardware and people care about the results01:42
psusiI was fairly certain it was crap before this story broke... now I'm sure01:42
PiciAnyway, that askubuntu link above has comments by a bunch of our kernel people in it.01:43
psusiin this case, they are showing a test case involving make -j64, which is absurd, and the uneducated masses see it and generalize it to achieving the same results for normal desktop loads01:43
anon^_^ebroder, because desktop responsiveness is an issue are load01:44
psusiI've been meaning to high five Kees when I see him on irc for his comment pointing out that this will have no effect for the average desktop user01:44
anon^_^whether this patch actually addresses that issue is a different question01:44
psusianon^_^, sure, but your average Ubuntu user does not typically have a load avg of 64 ;)01:44
ebroderIt's not just that. Your average Ubuntu user doesn't have non-trivial processes associated with more than one tty01:45
psusiexactly01:45
anon^_^well and then there's the issue of what constitutes load.01:46
anon^_^try running an luks lvm encrypted system moving writing files to disk and watch a desktop crawl to a halt when multitasking01:47
psusithe NT kernel has always had a feature where it boosts the scheduling priority of the thread that owns the foreground window.. I've long wondered why we don't have something like that01:49
Sarvatt_the userspace implementation of it very noticeably helps while dist-upgrading or building packages while browsing the web on an atom :)01:49
=== Sarvatt_ is now known as Sarvatt
psusiyou know... I've been running dist-upgrades a lot lately testing out lvm snapshots and don't have bad lag on gui apps while that goes on... I've also been playing with the apt options to make more use of triggers and avoid re-triggering the same things 12 times during the dist-upgrade, as well as using libeatmydata to stop the damn fsyncing dpkg normally does that slows things down so much for the last release or two01:51
superm1would it maybe make sense to use libeatmydata during initial install when using d-i?01:53
superm1but still leave default fsync behavior otherwise01:53
psusithere's a patch working its way into dpkg to add a switch to stop the extraneous syncs, but yes, it would02:04
superm1well a proper patch to turn it off sounds much better than hacking in an additional library02:06
psusiyep02:06
psusieither way, I'm happy to dist-upgrade in 10 minutes or less instead of 20 or more02:06

weaselis there some system that has sources of older packages (akin to snapshot.debian.org)?  specifically I'm looking for openssl_0.9.8k-7ubuntu8.3.dsc15:24
elmoweasel: https://launchpad.net/ubuntu/+source/openssl/0.9.8k-7ubuntu8.315:26
weaselthanks15:26
* weasel goes to interdiff 8.3 and 8.4, since you broke all tor relays15:26
* weasel hates libssl15:26

mdeslaurweasel: if you downgrade to 0.9.8k-7ubuntu8.3 it starts working again?15:29
weaselhard to tell, I don't have an ubuntu system :)15:30
weaselguess I'll set up a chroot somewhere15:30
weaselbut several people have reported that their relays stopped working after upgrading libssl, so /something/ is going on15:30
mdeslaurweasel: well, that distro are you running? the 8.4 release adds the same upstream security fix that everyone else used15:30
weaselmdeslaur: yup, so it appears15:31
weaselso the next step should probably be reproducing it in an ubuntu chroot and reproducing it with 0.9.8p from upstream15:31
mdeslaurweasel: could you please open a bug and track your progress in it? or ping me again if there's something we need to do?15:32

ebroderbuxy: The issue isn't in the size of the .debs. It's the size of the unpacked .debs - the desktop CD is all of the CDs unpacked, and then squashfs'd22:03
ebroderbuxy: And using lzma to compress the filesystem is infeasible because it breaks zsyncing from one daily CD to another (zsyncing becomes basically equivalent to re-downloading the whole CD, which isn't feasible for some of our QA procedures)22:05
ScottKlzma does help on the alternate CD though.22:06
ScottK(not that it particularly needs it)22:07
JanCebroder: zsyncing is only relevant for daily builds though, so it shouldn't be an issue for final builds?22:17
ebroderJanC: But you can't switch from one compression algorithm to another for the final build. That defeats the point of doing the testing22:19
ebroder(Keybuk was very proud of having found a bug in squashfs's gzip compression in the past)22:19
JanCwell, you can still test both22:19
JanCbut use the zsync'able version for "daily tests" with testdrive22:20
=== Auv5[Away] is now known as Auv5
JanCand people who don't care about bandwidth can use the lzma version22:21
JanCit would require changing the build process of course22:21
JanCand testing how much more space we get that way  ;)22:22
=== Auv5 is now known as Auv5[Away]
ebroderWell, I can at least give an estimate for the space savings. I'm rolling custom live CDs at work, and I tried building one with lzma just out of curiosity. lzma image was about 83% the size of the gzip image22:23
ebroderI was working with a custom set of packages, so your mileage may vary22:24
ebroderBut in any case, the people at the UDS session were fairly adament that we only generate one desktop spin, and that it must be incrementally updatable22:26
JanCebroder: so basically this is dictated by the QA people (which I understand)22:33
ebroderJanC: Yeah, basically22:33
* penguin42 wonders what % of users actually install from a physical CD these days22:34
JanCpenguin42: depends on if I have a live-USB with me or not  ;)22:35
penguin42JanC: Are you more likely to have a spare USB thumb or a blank CD with you?22:35
JanCpenguin42: I almost always have an official CD with me  ;)22:36
penguin42I was just wondering that given the minimum spec of machines these days very few can't boot off USB, heck there are probably more machines with no-optical drive rather than ones that can't boot off USB22:37
JanCas I have our locoteam's box of official-CDs-for-redistribution at my home...  :P22:37
JanCpenguin42: when we are at computer fairs we also distribute free CDs/CD-Rs, not free USB sticks  :P22:38
JanCso I imagine a lot of people install from CD still22:39
ebroderpenguin42: That came up at UDS, too. cjwatson made the point that even if people aren't using CDs, the size of a CD presents *some* limitation to keep the image size from ballooning out of control22:39
penguin42ebroder: Yeh that is true22:39
JanCof course if they bring an USB stick, we'll make it a bootable live-USB for them22:40
ebroderAnd also, with the rise of netbooks, you can no longer assume that computers have arbitrarily inflated specs. Disk space post-installation is a legitimate concern for netbooks, and controlling the CD size also conveniently controls the post-install size22:40
penguin42ebroder: Indeed post-install size is as important22:41
JanCIIRC Windows 7 is about 20 GiB post-install now...  :P22:41
ebroderHmm...I don't think it's actually that bad. More like 1022:42
JanCmaybe depends on what version of Win722:42
JanCand maybe what options you install22:42
JanCoh, and that was after all the updates22:43
penguin42heck, apparently you can get 1GB usb sticks for 59p now :-)22:44
JanC(and after more than 3 hours of installing updating)22:44
ebroderpenguin42: Sure, but you can get CDs for a fraction of that22:44
penguin42ebroder: Indeed, I was just being pleasently shocked by what they had come down to22:44
JanCfortunately it took only 15 minutes to install + update Ubuntu  ;)22:44
JanCPendulum: where do you find 1 GB USB sticks still?22:46
JanCpenguin42: where do you find 1 GB USB sticks still?22:47
JanC(sorry Pendulum ;) )22:47
penguin42JanC: Google found me http://www.kikatek.com/product_info.php?products_id=34487&source=froogle22:47
penguin42bah, if you click check availability it says sold out22:48
JanCpenguin42: cheapest I can find are 5-6 £22:52
JanCtaht's like 10× more...22:53
JanCwell, cheaper too, if you order a 1000 of them  :P22:55
