| Laibsch | ArneGoetje: I'm glad to hear that Japan is perceived as an important market to Canonical. I'm just not sure that replacing a font with one that looks worse is a good choice. | 00:33 |
| Laibsch | ArneGoetje: I'll talk to Hideki this week since I believe he may be able to give me some insight. If you have any further comments, I'd love to hear them as well. | 00:33 |

| persia | Laibsch: The font selection was done in communication and coordination with the Japanese team, on the basis that it was a better font for daily use. | 00:38 |
| Laibsch | I assume you're a part of that team? Who else, if I may ask. | 00:38 |
| Laibsch | As I said initially (been a few days now), the font looks *much* worse here. | 00:39 |
| Laibsch | But I wonder if that isn't some config problem | 00:39 |
| Laibsch | Right now, I'm just trying to understand | 00:39 |
| persia | Laibsch: https://launchpad.net/~japaneseteam | 00:39 |
| Laibsch | persia: how does the font look for you? | 00:41 |
| Laibsch | comparable? | 00:41 |
| Laibsch | vl-pgothic (old standard) vs. the new IPA derived font | 00:42 |
| persia | Laibsch: Different, but neither is more or less readable to me. | 00:42 |
| Laibsch | I see | 00:42 |
| Laibsch | the new one is much thinner for me | 00:42 |
| persia | The new font seems to have more delicate strokes, which is nice for low-dpi situations. | 00:42 |
| Laibsch | it's certainly readablle | 00:42 |

| YokoZar | dssi-vst needs a simple rebuild after my new wine1.0 package goes in (configuration issue) | 00:46 |

| YokoZar | persia: a retry | 00:57 |
| YokoZar | persia: Can anyone click that button? | 00:57 |
| TheMuso | YokoZar: You should be able to. | 00:57 |
| YokoZar | TheMuso: I'd used the button for my PPAs before, but for some reason I was expecting the real archive version of the button to only be available to archive admins | 00:57 |
| persia | YokoZar: Anyone with upload rights to the relevant package, yes. | 00:57 |
| YokoZar | Proper versioning for programs without version numbers is 0.0-YYYYMMDD yes? | 01:12 |
| Keybuk | YokoZar: I tend to prefer 0~YYYYMMDD-n | 01:14 |
| * persia doesn't like 0~ because Soyuz gets confused sometimes | 01:15 | |
| YokoZar | Keybuk: I guess that works better if they release a version "0" or 0.0 for some reason | 01:15 |
| Keybuk | persia: why would Soyuz get confused? | 01:15 |
| YokoZar | because it's less than 0? | 01:15 |
| persia | Keybuk: Dunno, and I haven't encountered it since intrepid. At that point I had some sync & upload failures I worked around with 0.0.0+... | 01:16 |
| * persia happily hasn't encountered the situation since | 01:16 | |
| Keybuk | actually | 01:25 |
| Keybuk | I'd probably just use YYYYMMDD if there was no version | 01:25 |

| jdong | kirkland: hey congrats on manpages.ubuntu.com fixing the "terminates output on bad character" bug :) | 02:09 |
| jdong | kirkland: I submitted a particularly ironic snprintf(3) manpage to TheDailyWTF a few weeks ago :) The manpage abruptly ended at "followed by the null byte, [EOF]" | 02:11 |
| kirkland | jdong: i saw that :-) | 02:11 |
| jdong | hehe :) | 02:11 |
| kirkland | jdong: i mean, i saw your pointer | 02:11 |
| kirkland | jdong: i think i fixed that bug | 02:12 |

| jdong | (the old version was much more amusing though!) | 02:12 |
| kirkland | jdong: yeah :-) | 02:12 |
| kirkland | jdong: still has some unprintable chars | 02:12 |
| jdong | yeah, whatever that special <?> character is before the quotes. | 02:12 |
| jdong | yup | 02:13 |
| kirkland | � | 02:13 |
| jdong | yeah they are littered throughout that manpage | 02:13 |
| kirkland | jdong: probably a w3m bug | 02:13 |
| jdong | ah, it goes through w3m? | 02:13 |
| kirkland | jdong: hmm, it's just a paren ( | 02:13 |
| jdong | other parens seem to do fine | 02:14 |
| kirkland | jdong: weird | 02:15 |
| kirkland | jdong: file a bug on it, if you like, and i'll have a deeper look some time | 02:15 |

| * ajmitch should probably upgrade at some point | 02:16 | |
| jdong | temugen: you mean special/regexing.that'll also match that? | 02:17 |
| jdong | ;-) | 02:17 |
| temugen | .net/.com/blah blah | 02:17 |
| jdong | ah, one of those enormous regexes | 02:18 |
| temugen | How else does OS X do it? | 02:18 |
| jdong | like the one for valid emails. | 02:18 |
| temugen | I assume they use magic | 02:18 |
| jdong | temugen: natural language parsing? | 02:18 |
| jdong | temugen: same way they pick dates and telephone numbers and addresses out of emails. | 02:18 |
| jdong | (I'd assume) | 02:18 |
| jdong | I HOPE with their 200 billion USD marketcap or whatnot they're not using a switch/case of regexes ;-) | 02:19 |
| ajmitch | you hope for a lot | 02:19 |
| jdong | ajmitch: hey one can be an optimist, right? ;-) | 02:20 |
| ajmitch | like with running experimental crack? sure... :) | 02:20 |

| RAOF | Um, has lvm2 broken boot for anyone else? | 05:58 |
| pitti | kees: there's a 115 MB mysql database and a 100 MB "qatest.tar.bz" in libvirt (presumably a packed image?) | 05:59 |
| pitti | hello ajmitch | 05:59 |
| pitti | RAOF: uh, how? | 05:59 |
| RAOF | Well, I'm not sure that it's the recent lvm2 upgrade, but that's my first guess. | 05:59 |
| RAOF | As in: enter the passphrase for your dm_crypt partition, get dumped to a recovery shell with the helpful message “CONTROL-D will teminate his shell and reboot the system” | 06:00 |
| RAOF | And I know there was a recent lvm2 change… | 06:00 |
| RAOF | I'm installing the previous version of lvm2 to see if that is in fact the problem. | 06:03 |
| RAOF | Looks like it was actually mountall. | 06:14 |
| pitti | RAOF: moutnall and plymouth were also updated yesterday | 06:18 |
| wgrant | RAOF: So I don't want to upgrade mountall and reboot if I use LUKS filesystems? | 06:19 |
| RAOF | Well… downgrading to mountall 2.13 gets me a mostly-working boot, it seems. | 06:20 |
| RAOF | By “mostly working” I mean that a recovery shell gets started, but the boot continues & I'm able to log in. | 06:20 |
| RAOF | wgrant: You know how to bring up a working system by hand, right? You should be fine! :) | 06:21 |
| wgrant | RAOF: Heh, I haven't had to do it in the new world yet. | 06:21 |
| RAOF | The trick is “service start dbus” - after that, everything's mostly up :) | 06:22 |
| slangasek | RAOF: bug #570289? | 06:24 |
| ubottu | Launchpad bug 570289 in plymouth "mountall assertion failure breaks boot process" [High,Incomplete] https://launchpad.net/bugs/570289 | 06:24 |
| slangasek | RAOF: if so, I need a backtrace on this sucker | 06:24 |
| RAOF | slangasek: That looks like the symptoms - how do I get a backtrace? | 06:26 |
| slangasek | RAOF: edit /etc/init/mountall cleverly, to spawn gdb with a non-interactive script and output redirected to somewhere useful under /dev | 06:29 |
| slangasek | RAOF: you will need to drop the 'expect daemon' line from mountall to accomplish this | 06:29 |
| pitti | would it be possible to enable apport and add a "started apport" condition? | 06:30 |
| slangasek | RAOF: you'll want to put a gdb batch script on the root filesystem somewhere, containing the commands 'run\nbt full' and launch gdb -x /path/to/script -batch mountall | 06:31 |
| slangasek | pitti: no, that would be a dependency loop | 06:31 |
| slangasek | but depending on how the filesystem is laid out, you might be able to call 'start apport' in the pre-start script of mountall | 06:31 |
| pitti | RAOF: or, if that fails, just add this: echo "|/usr/share/apport/apport %p %s %c" > /proc/sys/kernel/core_pattern | 06:32 |
| pitti | ah, I guess it'd fail anyway, since it needs a writable /var/crash/ | 06:32 |
| pitti | so, hand-crafted gdb is it then | 06:32 |
| RAOF | Let's give that a whirl | 06:36 |
| Keybuk | slangasek: my hunch on hat one | 06:36 |
| Keybuk | the process_pending_events processes whatever is in the list you're while looping on | 06:36 |
| Keybuk | which matches the assertion | 06:36 |
| Keybuk | so I thought the two functions in the loop migh just need to be swapped | 06:37 |
| slangasek | Keybuk: I wouldn't expect process_pending_events() to process outgoing requests, which is the only way I can see this causing that failure? | 06:37 |
| slangasek | since we loop while (ply_list_get_length (client->requests_to_send) > 0) | 06:38 |
| Keybuk | if the event is the closing of the file descriptor ? | 06:38 |
| slangasek | we certainly can't reverse the order of those calls, because that brings back the deadlock where both ends are trying to write at the same time | 06:38 |
| Keybuk | I might clear the pending events from the lis | 06:38 |
| slangasek | hmm | 06:38 |
| Keybuk | that was my guess | 06:40 |
| Keybuk | but I didn't want to go swapping the order around, since I was sure you had a very good reason for the functions being in that order | 06:40 |
| RAOF | Gah! | 06:40 |
| slangasek | that might explain it; I'll have to go code-digging to see | 06:40 |
| slangasek | RAOF: ? | 06:40 |
| RAOF | The screen gets cleared just after mountall gets called, so I can't see any output, and / is still read-only, so I can't pipe output anywhere | 06:41 |
| slangasek | Keybuk: yeah, the reason not to swap them is bug #554737 :) | 06:41 |
| ubottu | Launchpad bug 554737 in plymouth "ply_boot_client_flush() does not read replies (plymouth stuck during/after filesystem check or error)" [High,Fix released] https://launchpad.net/bugs/554737 | 06:41 |
| slangasek | RAOF: no, output it to /dev | 06:41 |
| slangasek | (I think I said this :) | 06:42 |
| RAOF | You did, I just didn't pay enough attention :) | 06:42 |
| Keybuk | and now you go hungry | 06:45 |
| Keybuk | ah, I thought I had just eaten too much mexican food and couldn't type | 06:48 |
| Keybuk | instead it turns out that the 't' key was falling off | 06:48 |
| slangasek | bryceh: have you learned anything more about bug #553708? | 06:51 |
| ubottu | Launchpad bug 553708 in plymouth "ubuntu-logo theme: Mount error message is overlayed with the S&M message" [Medium,Triaged] https://launchpad.net/bugs/553708 | 06:51 |
| slangasek | RAOF: is that working better? | 06:52 |
| Keybuk | the "S&M message" ? | 06:53 |
| RAOF | Ok. Now it is redirecting to /dev, just an empty file! The mountall script now has “exec gdb -x /gdbscript -batch mountall > /dev/mountall.log” in the obvious place, and /gdbscript has “run\nbt full” (with \n expanded into a real newline). | 06:53 |
| Keybuk | ah, I'd forgotten that one | 06:53 |
| Keybuk | Unable to mount your filesystem. | 06:53 |
| Keybuk | Say the safe word to abort. | 06:53 |
| RAOF | Ahem. :) | 06:53 |
| slangasek | RAOF: maybe add a 2>&1 as well? | 06:54 |
| slangasek | (not sure why that would be needed, but) | 06:54 |
| RAOF | Yeah - gdb should be on stdout, surely. Anyway… added. Let's give *that* a whirl. | 06:55 |
| RAOF | Nope. Empty again. | 06:55 |
| slangasek | hmm | 06:55 |
| RAOF | Hm. It also has changed the behaviour somewhat. Rather than waiting for me to unlock the dmcrypt device, it's now failing without prompting for the passphrase. | 06:56 |
| slangasek | er - mountall really shouldn't affect that | 06:57 |
| slangasek | can you post your full /etc/init/mountall.conf? | 06:57 |
| slangasek | well, though I guess if mountall is failing before even emitting virtual-filesystems, udev won't start either | 06:58 |

| Damascene | I want to create personal page on ubuntu wiki, were should I ask? | 07:20 |
| RAOF | AHA! gdb looks like it wants to be able to write to / | 07:22 |
| slangasek | RAOF: 2>&1 has to go after > /dev/mountall.log | 07:22 |
| slangasek | oh? | 07:22 |
| * RAOF never gets shell redirections right the first time :( | 07:22 | |
| RAOF | If I remount / rw before calling gdb, I get some output in /dev/mountall.log. | 07:23 |
| slangasek | RAOF: "2>&1" == "make fd 2 point to the same place that fd 1 currently points" | 07:23 |
| slangasek | RAOF: interesting, ok | 07:24 |
| * micahg could see how that could be confusing, if you use tee, the redirection is before the pipe | 07:25 | |
| RAOF | However, that output in /dev/mountall.log doesn't include a backtrace, and is just mountall saying “yup, your drive doesn't need to be fsck'd” | 07:25 |
| Keybuk | micahg: that's because a pipe is a different part of shell language | 07:26 |
| slangasek | RAOF: ah; you may have to trap SIGABRT explicitly | 07:26 |
| Keybuk | |, like &&, ||, ;, etc. separates distinct commands | 07:26 |
| Keybuk | so the redirect has to go on the left of the pipe, otherwise it applies to the command after the pipe rather than the command before | 07:26 |
| micahg | Keybuk: yeah, I understand, but I took a double take when I saw that since I'm used to doing 2>&1 | tee /tmp/foo | 07:26 |
| slangasek | RAOF: hmm, no - gdb handles SIGABRT by default | 07:26 |
| RAOF | I thought it did, yeah. | 07:27 |
| Keybuk | micahg: it makes a kooky sense | 07:27 |
| micahg | Keybuk: it makes great sense if everything is in perspective, slangasek described it well | 07:27 |
| slangasek | RAOF: do you still get the abort message somewhere? | 07:27 |
| Keybuk | micahg: 2>&1 | there means "make fd 2 point to the same place that fd 1 currently points" still - the pipe means that fd 1 is always connected to the next process, rather than stdout | 07:27 |
| Keybuk | whereas >log 2>&1 vs. 2>&1 >log now make sense as different | 07:28 |
| * micahg has a lot to learn still | 07:29 | |
| Keybuk | more fun .. what does ... cmd >log 2>&1 | less do? :p | 07:30 |
| Keybuk | and to make your brain really hurt, try that in zsh ;-) | 07:31 |
| ion | Depends on the shell. In dash, less gets nothing. In zsh, it gets the output from cmd. | 07:31 |
| Keybuk | zsh's pipeline handling is based largely on a dare | 07:31 |
| ion | Just like echo foo >bar >baz works in zsh. | 07:31 |
| Keybuk | I like <(...) | 07:32 |
| RAOF | Accursed thing! What's preventing keyboard input? | 07:32 |
| Keybuk | e.g. diff -u <(sort file1) <(sort file2) | 07:33 |
| ion | Yes, <(...) is nice. I use it frequently in xargs -a <(find ... or dpkg -L ... or something) -d'\n' cmd ... where i want cmd’s stdin to be the terminal. | 07:33 |
| ion | For instance, xargs -a (ls | shuf) -d'\n' mplayer to play the videos from cwd in random order. | 07:34 |
| ion | <( | 07:34 |
| RAOF | There's a lot of craziness here - if I don't unlock the dmcrypt partition in break=mount it seems that the recovery shell and the cryptsetup unlock dialog fight for input, and neither gets any. | 07:34 |
| slangasek | 'dmcrypt'? Is that using cryptsetup, or not? | 07:35 |
| slangasek | oh, you say that it is | 07:35 |
| RAOF | Well, to unlock it I run “cryptsetup luksOpen ...”, so I presume that's using cryptsetup :) | 07:36 |
| slangasek | RAOF: try commenting out 'console output' in /etc/init/cryptdisks-udev.conf | 07:36 |
| ion | Glob expansion in zsh is especially nice. echo foo/**/a*(.) (equivalent to find foo -type f -name 'a*' -print0 | xargs -0 echo) | 07:36 |
| Keybuk | ion: indeed; though we're kinda getting in the way of debugging here, so I'm going to shut up P: | 07:37 |
| ion | Hehe | 07:37 |
| RAOF | Eh, not that much in the way :) | 07:37 |
| RAOF | slangasek: /etc/init/cryptdisks-udev.conf doesn't *have* a “console output” stanza. | 07:40 |
| slangasek | really? | 07:41 |
| RAOF | http://pastebin.com/JBvmKQ74 is the full output of mountall.log, with stderr redirected appropriately. | 07:41 |
| slangasek | oh, I guess I have a modified version of that file then :P | 07:41 |
| RAOF | But that output is after manually unlocking the crypted disc, which doesn't have the same behaviour. | 07:42 |
| slangasek | Keybuk: ^^ maybe you can interpret that pastebinned output? gdb seems to be unhappy with being launched from upstart or something | 07:44 |
| * slangasek runs to grab breakfast | 07:44 | |
| Keybuk | you can't launch gdb from upstart | 07:44 |
| Keybuk | not without taking out the "expect ..." bit | 07:45 |
| RAOF | Keybuk: You mean the “expect daemon” bit? That's commented out. | 07:45 |
| Keybuk | oh, dunno then | 07:45 |
| * RAOF comments out random “console output” stanzas | 07:48 | |
| Keybuk | try "console owner"? | 07:48 |
| Keybuk | maybe the ioctl is inappropriate unless it's married? | 07:49 |
| RAOF | That should totally be a technical term! | 07:49 |
| Keybuk | "how do you like your ioctls? raw or cooked?" | 07:50 |
| RAOF | Hey! Since I've already remounted / read-write I can just write the gdb log somewhere permanent! | 07:55 |
| pitti | RAOF: I set up a test system with cryptsetup-LUKS LVM now, in case you need more testing for something | 07:57 |
| RAOF | So, “console owner” seems to have cleared up those inappropriate ioctl messages, but there's still no backtrace. | 08:05 |
| RAOF | slangasek: Shall we just go on a printf debugging spree? | 08:07 |
| dholbach | good morning | 08:07 |
| slangasek | RAOF: cjwatson's suggestion just now was to adjust the mountall job to call chdir /dev and set 'ulimit -c unlimited', so that you can get a core file there - rather than trying to get gdb to work under upstart | 08:22 |
| slangasek | then we can postprocess at leisure | 08:23 |

| RAOF | Keybuk: got a better one, then rebuilt everything with DEB_BUILD_OPTIONS=noopt,nostrip and installed further dbgsym packages. | 08:56 |

| Keybuk | right, pretty straight forward | 09:02 |
| Keybuk | just to confirm sanity | 09:03 |
| Keybuk | if you up a couple of frames and | 09:03 |
| Keybuk | p client->requests_to_send | 09:04 |
| Keybuk | do you get 0 | 09:04 |
| Keybuk | ? | 09:04 |
| RAOF | I presume you meant p *client->requests_to_send? | 09:05 |
| RAOF | $2 = {first_node = 0x0, last_node = 0x0, number_of_nodes = 0} | 09:05 |
| Keybuk | right | 09:05 |
| Keybuk | ok | 09:05 |
| Keybuk | so pretty straight forward | 09:05 |
| Keybuk | when it flushes the plymouth fd, there are requests to send | 09:06 |
| Keybuk | the first call is to process_pending_events () | 09:06 |
| Keybuk | this can clearly send events (it polls on write) | 09:06 |
| Keybuk | so it writes out the queue | 09:06 |
| Keybuk | there are now no events to flush | 09:07 |
| Keybuk | so process_pending_requests will assert | 09:07 |
| Keybuk | while (ply_list_get_length (client->requests_to_send) > 0) | 09:07 |
| Keybuk | { | 09:07 |
| Keybuk | ply_event_loop_process_pending_events (client->loop); | 09:07 |
| Keybuk | ply_boot_client_process_pending_requests (client); | 09:07 |
| Keybuk | } | 09:07 |
| Keybuk | ... | 09:07 |
| Keybuk | slangasek: since ply_event_loop_process_pending_events () will *call* ply_boot_client_process_pending_requests () if the fd is writable | 09:07 |
| Keybuk | isn't that loop wrong? | 09:07 |
| Keybuk | should it not simply be | 09:07 |
| Keybuk | while (ply_list_get_length (client->requests_to_send) > 0) | 09:08 |
| Keybuk | ply_event_loop_process_pending_events (client->loop); | 09:08 |
| cjwatson | <slangasek> does it call it? I don't think it does | 09:08 |
| Keybuk | it definitely definitely definitely does | 09:09 |
| Keybuk | that's the whole purpose of that function | 09:09 |
| Keybuk | to be called from inside ply_event_loop | 09:09 |
| Keybuk | look at ply_boot_client_queue_request | 09:09 |
| === almaisan-away is now known as al-maisan | ||
| Keybuk | when a request is queued, if client->requests_to_send is 0 then it sets up an fd watch that calls ply_boot_client_process_pending_requests() whenever the fd is writable, then queues the request to send | 09:10 |
| cjwatson | right | 09:10 |
| Keybuk | so all the time that client->requests_to_send is *not* 0, that function will be called whenever the fd is writable | 09:10 |
| cjwatson | OK. So why isn't this asserting for everybody? | 09:10 |
| Keybuk | and in the bottom of the function itself, it clears its own watch once the list is empty again | 09:10 |
| Keybuk | I guess for most people, the epoll says the fd isn't writable | 09:11 |
| Keybuk | and then it blocks in the second function | 09:11 |
| Keybuk | but for RAOF, the epoll says it's writable | 09:11 |
| Keybuk | so that assert | 09:11 |
| Keybuk | very fast machines assert maybe? | 09:11 |
| Keybuk | or machines with oodles of memory (big socket buffs) | 09:11 |
| cjwatson | yes, that could make sense. In that case it isn't particularly configuration-specific and I think we ought to respin | 09:12 |
| Keybuk | it'll also only assert if you manage to completely *drain* the request list inside that first call to epoll | 09:12 |
| cjwatson | so pretty racy | 09:12 |
| Keybuk | and the request list when fsck is concerned is pretty long, so hard to drain | 09:12 |
| Keybuk | so yeah, the assert pattern would look something like | 09:13 |
| Keybuk | - there are requests when flush() is called | 09:13 |
| Keybuk | - the fd polls for writing (write will not block) | 09:13 |
| Keybuk | - all of the requests are able to be written before write would block | 09:14 |
| Keybuk | - thus by the next call, there are no longer any requests | 09:14 |
| Keybuk | ok, my work here is done | 09:15 |
| * Keybuk hands over to the day shift | 09:15 | |
| SuN__ | I can not log gives me a black screen and reboot ... how to help me reinstall | 09:15 |
| kees | pitti: yeah, part of the downside to lots of tests is lots of test data :) that said, if you want to extract a single test, scripts/make* to build test tarballs | 09:29 |
| lucas | what's the current process to upload a one-liner bugfix for a universe package? | 09:36 |
| pitti | lucas: upload it and make sure that the changelogaand linked bug properly document the change | 09:37 |
| lucas | pitti: thanks | 09:38 |
| lucas | pitti: a fake sync from debian is fine, too? | 09:38 |
| pitti | lucas: same criteria: depends on whether the debdiff is 100% obvious and regression proof | 09:39 |
| lucas | ok | 09:39 |
| pitti | lucas: aside from that, a big concern is that builds must be completed soon, to avoid having pending build records at release | 09:40 |
| pitti | lucas: for most (i. e. relatively small) packages that's not a problem | 09:40 |
| pitti | it might be for things the size of linux/OO.o/openjdk | 09:40 |
| lucas | pitti: ok, will upload ASAP | 09:41 |

| tseliot | jibel: that sounds like a bug in the ati installer to me but still I can see how badly it can affect dist-upgrades. | 09:58 |
| tseliot | slangasek: ^^ | 09:58 |
| cjwatson | ogasawara_: bug 570542 (iso-testing) looks like a straightforward fix - maybe SRU? | 10:06 |

| jibel | tseliot, not really because once you've tried to install the ubuntu package you cannot uninstall the ati driver anymore. | 10:08 |
| ogasawara_ | cjwatson: ack, thanks | 10:08 |
| jibel | tseliot, shouldn't we detect the presence of the ati driver before attempting to remove any of its files ? | 10:08 |
| tseliot | jibel: what I meant to say is that deb packages should uninstall cleanly without having to look up some random file to see what it has installed | 10:09 |
| tseliot | jibel: I know that we call /usr/share/ati/fglrx-uninstall.sh in the preinst so removing /etc/ati/after that should solve the problem | 10:11 |
| jibel | tseliot, indeed | 10:11 |
| tseliot | slangasek, pitti: do you agree to include this trivial fix in the final release (for the sake of dist-upgrades)? | 10:13 |
| pitti | tseliot: upgrades can easily be fixed as SRUs, too | 10:13 |
| tseliot | pitti: sure but we would break a lot of dist-upgrades in the mean time... | 10:14 |

| cjwatson | oh for god's sake why do people keep perpetuating XML configuration files | 15:15 |
| cjwatson | (netcf) | 15:15 |
| cjwatson | or actually a library API involving XML strings! nuts | 15:15 |
| cjwatson | can't say I'm wildly enthused, but whatever | 15:16 |
| kirkland | cjwatson: just curious; the kvm/libvirt community is talking a lot about netcf right now | 15:17 |
| cjwatson | this isn't a veto, it's just a lack of enthusiasm/interest | 15:18 |
| kirkland | cjwatson: as a command line replacement for networkmanager, and useful for packages to setup networking consistently | 15:18 |
| kirkland | cjwatson: no problem; i'm just asking, really | 15:18 |
| cwillu_at_work | cjwatson, can I interest you in a json configuration database? :p | 15:18 |
| kirkland | cjwatson: i doubt the server team will have the bandwidth or clout to drive this into Maverick | 15:18 |
| cjwatson | I would certainly like a command-line NetworkManager equivalent or frontend; there appear to be several possibilities for that | 15:18 |
| cjwatson | cwillu_at_work: no :-) | 15:18 |
| kirkland | cjwatson: conman? (or what else)? | 15:18 |
| slangasek | network manager itself doesn't need a GUI frontend to do its job | 15:19 |
| cjwatson | no, I've seen at least one actually based on NM | 15:19 |
| cjwatson | connman is entirely separate | 15:19 |
| slangasek | you can store all the configs under /etc/NetworkManager | 15:19 |
| cjwatson | right, you then just need something command-line to talk dbus to it | 15:19 |
| * slangasek nods | 15:19 | |
| cwillu_at_work | people who put capital letters into pathnames should be shot | 15:19 |

| pitti | ah, it was re-enabled after beta-2 indeed | 16:42 |
| kirkland | pitti: what's this, in a nutshell? | 16:42 |
| pitti | kirkland: I just overheard your last couple of comments; did you already identify something else as the cause? or are you talking about dpkg | 16:42 |
| kirkland | pitti: i'm suspect of dpkg, as it's the installation steps of the server installer that are really, really slow | 16:43 |
| pitti | kirkland: during unpack, dpkg now calls fsync() a few times, to ensure data integrity (it previously caused a lot of 0-byte files on power failures, etc.) | 16:43 |
| ogra | pitti, only during unpack ? | 16:44 |
| pitti | kirkland: see dpkg 1.15.5.6ubuntu4 changelog | 16:44 |
| kirkland | pitti: yeah, i have two levels of UPSes here, won't be any powerfailures on my end... how do i make it go-fast again? | 16:44 |
| ogra | really smells like the cause for bug 532733 which we are unable to debug properly | 16:44 |

| pitti | ogra: well, I checked the unpack and configure times of openoffice.org-common | 16:44 |
| slangasek | kirkland: install on ext3 instead of ext4 | 16:44 |
| ttx | pitti: that would match my experience. dpkg cycles appearing to hang at various points | 16:44 |
| kirkland | :-/ | 16:45 |
| slangasek | kirkland: if that makes it faster, then this is what it is | 16:45 |
| kirkland | slangasek: oh, okay | 16:45 |
| kirkland | slangasek: i'll do that next UEC machine | 16:45 |
| ion | Two levels of UPSes? Sounds like worse power efficiency with little benefit over a single UPS to me. :-) | 16:46 |
| kirkland | ion: it's a laptop, with a battery, plugged into a UPS | 16:46 |
| cjwatson | yeah, OK, so the fsync thing would match up | 16:48 |
| cjwatson | but that is not going to be changed now for lucid | 16:48 |
| cjwatson | I'm very unhappy about ext4's behaviour here. dpkg really has no good option | 16:49 |

| ogra | kirkland, if ext3 is supposed to fix it then its not 532733 :( rootstock uses ext3 by default (even used ext2 before) | 16:50 |
| cjwatson | kirkland: back to grub2; is there a recipe? | 16:50 |
| cjwatson | ogra: the dpkg fsync thing would not have caused hangs | 16:50 |
| kirkland | cjwatson: there is no recipe; i can halt UEC testing to go and try to reproduce that | 16:50 |

| cjwatson | ogra: no, it's a slowdown, not a hang | 16:51 |

| chrisccoulson | pitti - it wasn't, that should work | 16:51 |
| chrisccoulson | seb128 already mentioned an issue to me | 16:51 |
| pitti | chrisccoulson: trying on the current live system, it doesn't | 16:51 |
| ogra | cjwatson, ah, k, we surely see a solid hang | 16:52 |
| chrisccoulson | pitti - there is an issue currently where it only displays a non-localised offline page without any layout | 16:52 |
| chrisccoulson | but i don't know why it's still trying to access http://start.ubuntu.com/10.04//Google/ with no network connection | 16:52 |
| chrisccoulson | pitti - network manager is indicating that the network connection is disconnected? | 16:53 |
| pitti | chrisccoulson: yes; I didn't give it a wpa password | 16:54 |
| chrisccoulson | pitti - ok, i'm slightly confused then. i'll have a think about that ;) | 16:54 |
| pitti | chrisccoulson: you don't get that on the live system? | 16:54 |
| chrisccoulson | pitti - tbh, i've only tried it on my installed system | 16:54 |

| ion | Why does fsync cause such a performance difference on ext4? | 17:03 |
| chrisccoulson | pitti - ok, confirmed from a guest session, but only on the first attempt | 17:03 |
| kirkland | ion: apps are required to call fsync on ext4 | 17:03 |
| joaopinto | I had to add barriers=0 to make ext4 usable for sbuilds | 17:09 |
| cjwatson | ion: fsync is considerably more than what dpkg actually needs | 17:12 |
| cjwatson | ion: dpkg requires that either old or new file is on disk, not somewhere in between | 17:12 |
| cjwatson | ion: ext4's requirement to fsync then rename means that it has to stop and wait for the new file to land | 17:12 |
| cjwatson | this is fundamentally bound to be slower | 17:13 |
| cjwatson | it is a filesystem misdesign caused by the filesystem designers optimising for theoretical benchmarks rather than for real-world applications | 17:13 |
| cjwatson | and this is just a demonstration of why the recommendations made repeatedly and loudly by the filesystem designers cause poor performance | 17:14 |
| ion | I mean, wouldn’t the added fsync calls cause a similar slowdown on ext3, too? | 17:15 |
| cjwatson | empirically, the added fsync calls are within experimental error on ext3 | 17:16 |
| cjwatson | I do not know why | 17:16 |
| ion | Also, would it help if dpkg only used fdatasync? | 17:16 |
| kirkland | cjwatson: would it be possible to disable the fsync calls when dpkg is run from d-i ? | 17:17 |
| cjwatson | kirkland: not for lucid. | 17:17 |
| cjwatson | this WILL NOT CHANGE FOR LUCID. excuse me for shouting. | 17:17 |
| cjwatson | far too risky | 17:17 |
| kirkland | cjwatson: necessarily, if there's a power loss during installation, you're starting over from scratch anyway | 17:18 |
| kirkland | cjwatson: that's very, very, very unfortunate | 17:18 |
| cjwatson | I've discussed this briefly with dpkg upstream, and one possibility is to add an option for it | 17:18 |
| cjwatson | kirkland: *shrug* | 17:18 |
| cjwatson | use ext3 | 17:18 |
| cjwatson | it doesn't suck | 17:18 |
| kirkland | cjwatson: great; let's switch ubuntu server default install to use ext3 then | 17:18 |
| cjwatson | let's release-note it. | 17:18 |
| pitti | OOI, does anyone happen to know if btrfs will handle this any better? | 17:19 |
| cjwatson | ion: maybe, I'm not sure | 17:19 |
| cjwatson | look, I'm not especially happy about the slower performance, but I don't think it's release-critical compared to data-loss bugs | 17:21 |
| cjwatson | and I don't think that it justifies the risk of making non-trivial changes at this point | 17:21 |
| ion | I don’t find ten more minutes of install time too big a problem. It’s how much out of the total runtime the installation is going have in its lifetime? :-) | 17:23 |
| kirkland | ion: ten minutes sucks, considering i'm in the middle of approximately 40 installations today | 17:23 |
| pitti | well, but integrity >> speed at this point, especially for installing updates in a production system | 17:24 |
| elmo | just to add to an alternative voice to this | 17:24 |
| elmo | it's not ten minutes on real server hardware | 17:24 |
| elmo | and in my workflow, I don't care how long installs take | 17:24 |
| elmo | but i care *very much* that they're consistent and correct | 17:24 |
| Keybuk | and to add a voice with a different POV | 17:25 |
| elmo | (how long installs take + within reason) | 17:25 |
| elmo | (and believe me, I've done a lot of ubuntu server installs this week too) | 17:25 |
| elmo | (except they were hardy, but whatever ;-) | 17:26 |
| Keybuk | one of the problems with calling fsync() all the time is that in filesystems which do delayed allocation, have extents, etc. like XFS, ext4 and btrfs, is that it will lay down the files at every fsync | 17:26 |
| Keybuk | which will increase the likelihood of fragmentation | 17:26 |
| ion | keybuk: Yes, the filesystem sucks indeed. :-) | 17:26 |
| cjwatson | right, and FAOD I think the whole "must call fsync before rename" thing is stupid and wrong | 17:26 |
| cjwatson | but rock, hard place | 17:26 |
| kirkland | pitti: i wholeheartedly agree on the update scenario; but i wholeheartedly disagree on the base install scenario | 17:27 |
| cjwatson | look, there certainly are problems that would merit a respin at this point; but ones that require fairly deep modifications to the package manager aren't, imo, among them | 17:27 |
| elmo | kirkland: I, for one, like my base installs to have integrity :-P | 17:27 |
| kirkland | elmo: one fsync at the end takes care of that | 17:28 |
| pitti | kirkland: right, I agree to installs; but too late now :/ | 17:28 |
| cjwatson | fsync is per-file-descriptor, FYI | 17:28 |
| cjwatson | YM sync | 17:28 |
| kirkland | pitti: cjwatson: is this something that can be fixed in 10.04.1 ? | 17:28 |
| joaopinto | the ext4 choice for servers as other implications depending on the server role, e.g. mysql may get a major performance hit | 17:28 |
| cjwatson | and I agree that there are better ways that the installer could deal with this, just not for 10.04 | 17:28 |
| kirkland | since 10.04 has shipped? | 17:28 |
| cjwatson | kirkland: potentially yes | 17:28 |
| ion | Yeah, a more intelligent filesystem might as well only flush what’s needed and keep other allocations delayed. | 17:28 |
| cjwatson | I'd like to agree something with dpkg upstream | 17:28 |
| Keybuk | cjwatson: in at least ext4, fsync is per filesystem | 17:29 |
| cjwatson | Keybuk: sure, but the API is per-file | 17:29 |
| cjwatson | dpkg is not entitled to make that assumption | 17:29 |
| Keybuk | cjwatson: yes, but then if you're being paranoid, dpkg needs to also open the directory file descriptor and fsync() that | 17:29 |
| Keybuk | which it doesn't | 17:29 |
| cjwatson | true | 17:29 |
| pitti | Riddell: packagekit released to -updates; thanks for testing! | 17:30 |
| cjwatson | and no doubt we'll pay the price for forgetting that in terms of bug reports | 17:30 |
| Riddell | pitti: great | 17:31 |
| jcastro | lucas: I've scheduled the debian session for Tuesday morning. | 17:34 |
| joaopinto | kirkland, if you can somehow remount with barriers=0 before install you should get an ext3 similar performance | 17:34 |
| cjwatson | I don't believe the installer offers an interface for that | 17:35 |
| ion | Ah, one using barriers and one not doing so would probably explain the major difference performance between the filesystems. | 17:35 |
| cjwatson | FTR this affects alternate install CDs much more than servers; I'm not picking on server here | 17:36 |
| cjwatson | (but fortunately it doesn't particularly affect desktop since ubiquity operates differently) | 17:36 |
