| mojo__ | Keybuk: thanks for ur advice yesterday, i finally got my script ported to access directly the keyboard | 01:49 |
|---|---|---|
| mojo__ | Keybuk: and it works | 01:49 |
| mojo__ | Keybuk: :) | 01:50 |
| mojo__ | Keybuk: i just have 1 question, I created my weird daemon file in /etc/event.d/ | 01:50 |
| mojo__ | Keybuk: in which I make it start on level 2,3,4,5 | 01:51 |
| mojo__ | Keybuk: when I reboot, the daemon is not started | 01:53 |
| Keybuk | how did you write it? | 02:04 |
| mojo__ | Keybuk: u still there? | 02:39 |
| mojo__ | plese excuse me, i will flood the irc a bit | 02:40 |

| mojo__ | start on runlevel 2 | 02:40 |
| mojo__ | start on runlevel 3 | 02:40 |
| mojo__ | start on runlevel 4 | 02:40 |
| mojo__ | start on runlevel 5 | 02:40 |
| mojo__ | stop on runlevel 0 | 02:40 |
| mojo__ | stop on runlevel 1 | 02:40 |
| mojo__ | stop on runlevel 3 | 02:40 |
| mojo__ | stop on runlevel 6 | 02:40 |
| mojo__ | console output | 02:40 |
| mojo__ | exec /var/www/perlscript/control.pl | 02:40 |
| mojo__ | respawn | 02:40 |
| mojo__ | Keybuk: this is the code | 02:40 |
| Keybuk | should work | 02:40 |
| mojo__ | i know | 02:41 |
| mojo__ | but when I restart | 02:41 |
| mojo__ | the script doesn't executed | 02:41 |
| mojo__ | .... | 02:41 |
| mojo__ | or should i add in | 02:41 |
| mojo__ | start on startup? | 02:41 |
| Keybuk | assuming you're using Ubuntu? | 02:44 |
| mojo__ | yes | 02:45 |
| mojo__ | Keybuk: Ubuntu Gutsy | 02:45 |
| Keybuk | how do you know it's not running? | 02:46 |
| mojo__ | well | 02:46 |
| mojo__ | initctl list | 02:46 |
| mojo__ | i know immediately | 02:47 |
| Keybuk | right | 02:47 |
| Keybuk | but it may have run, and then failed and restarted enough times to be stopped | 02:47 |
| mojo__ | hmm | 02:47 |
| mojo__ | but it works | 02:47 |
| mojo__ | if i run start weird | 02:47 |
| mojo__ | or stop weird | 02:47 |
| Keybuk | that's why I suspect it is failing for some reason when run at startup | 02:48 |
| mojo__ | hmm | 02:48 |
| mojo__ | Keybuk: hint on debug? | 02:48 |
| Keybuk | replace exec with | 02:48 |
| Keybuk | script | 02:48 |
| Keybuk | touch /tmp/foo | 02:48 |
| Keybuk | exec ... | 02:48 |
| Keybuk | end script | 02:48 |
| Keybuk | and see whether /tmp/foo apperas | 02:49 |
| mojo__ | okay | 02:49 |
| mojo__ | i do it now | 02:49 |
| mojo__ | Keybuk: rebooting | 02:50 |
| mojo__ | Keybuk: the bug might be with the order services starts | 02:50 |
| Keybuk | exactly | 02:50 |
| Keybuk | you'll be starting before anything in /etc/rc2.d | 02:50 |
| mojo__ | Keybuk: b/c my script need mpdd and lcdd | 02:51 |
| mojo__ | Keybuk: those 2 are SysVinit services | 02:51 |
| Keybuk | oh | 02:51 |
| Keybuk | that's why it doesn't work then :) | 02:51 |
| mojo__ | Keybuk: if those services are not started, then my script won't work | 02:51 |
| mojo__ | Keybuk: can u show me how to make sure it loads after those 2 | 02:51 |
| Keybuk | so yeah, your service is being started and then fails | 02:51 |
| Keybuk | start on stopped rc2 | 02:51 |
| Keybuk | start on stopped rc3 | 02:51 |
| Keybuk | etc. | 02:51 |
| Keybuk | instead of on runlevel 2 | 02:51 |
| mojo__ | okay | 02:52 |
| mojo__ | perfecto!!! | 02:52 |
| mojo__ | it works!! | 02:52 |
| mojo__ | i am so happy! | 02:52 |
| mojo__ | thank you so much u know | 02:53 |

| Arafangion | Keybuk: Hey. | 06:35 |
| Keybuk | heyhey | 06:35 |
| Arafangion | I took another shot at troubleshooting upstart yesterday, with your quick bash script. | 06:36 |
| Arafangion | exec strace /sbin/init "$@" | 06:36 |
| Arafangion | Unfortunately, that means that /sbin/init is no-longer associated with process id 0, which it explicitly checks before dying. | 06:36 |
| Arafangion | Which makes sense, I remember seeing that before. | 06:37 |
| Keybuk | oh, right | 06:37 |
| Keybuk | damn | 06:37 |
| Keybuk | I'd forotten that | 06:37 |
| Arafangion | Next time I feel like it, I _could_ remove that check from the source code myself, and recompile init... | 06:37 |
| Arafangion | I'm thinking I might as well just revert to bsd-style init, though - unless you have some good ideas? | 06:39 |
| Keybuk | the way I'd debug it would be to break in the initramfs before exec'ing init | 06:40 |
| Keybuk | and then open up a new vt with bash running | 06:40 |
| Keybuk | so I could run initctl events and initctl jobs from it | 06:40 |
| Arafangion | What initramfs? ;) | 06:41 |
| Keybuk | make one :p | 06:42 |
| Keybuk | init is hard to debug | 06:43 |
| Keybuk | you have a strange unexpected behaviour | 06:43 |
| Keybuk | you may be able to get away with something like: | 06:43 |
| Keybuk | start on startup | 06:43 |
| Keybuk | script | 06:43 |
| Keybuk | initctl jobs > /tmp/jobs.txt | 06:43 |
| Keybuk | initctl events > /tmp/events.txt | 06:44 |
| Keybuk | wait | 06:44 |
| Keybuk | end script | 06:44 |
| Keybuk | but you'd need a writeable filesystem for that | 06:44 |
| Keybuk | oh and "&" on the ends of those lines :p | 06:44 |
| Arafangion | It's writable very early on. | 06:44 |
| Keybuk | earlier than the mount_stage1 you're trying to debug? :p | 06:44 |
| Keybuk | actually | 06:44 |
| Arafangion | It's the _end_ of mount_stage1 that's the problem. :) | 06:45 |
| Keybuk | your mount_stage1 is console output right? | 06:45 |
| Keybuk | add initctl jobs & initctl events & to the top of it | 06:45 |
| Arafangion | That's a good idea. | 06:45 |
| Arafangion | Maybe upstart needs a more extreme --debug form which collects as much info as possible in a useful form, saving it to /var/log/upstart.dbg? | 06:46 |
| Arafangion | Which remounts the filesystem in rw by default - this is just a debug, so that should be an acceptable special-case? | 06:47 |
| Keybuk | there's no really portable way to remount the root rw | 06:48 |
| Keybuk | mount -o rw,remount / only works for the 95% case | 06:48 |
| Keybuk | (which may be enough) | 06:48 |
| Arafangion | 5% of the case where it simply outputs to the screen should satisfy the rest. ;) | 06:59 |
| Keybuk | heh | 06:59 |
| Arafangion | And besides, those who can't simply remount the root filesystem are probably very aware of that. ;) | 06:59 |
| Keybuk | actually, if you can get syslog started early enough, it'll get logged that way | 06:59 |
| Keybuk | I often capture --debug by doing init=/bin/bash | 07:00 |
| Keybuk | mount -o rw,remount / | 07:00 |
| Keybuk | /etc/init.d/sysklogd start | 07:00 |
| Arafangion | Not many people run from read-only flash drives or cdr's, and not know about it. :) | 07:00 |
| Keybuk | exec /sbin/init | 07:00 |
| Arafangion | You don't get the issue with the proc id check? | 07:00 |
| Keybuk | or LVM, RAID, etc. that requires more complex bootstrap | 07:00 |
| Keybuk | not if you exec it | 07:00 |
| Arafangion | Ahh, point. | 07:00 |
| Arafangion | This system is actually running from a USB stick, btw. ;) | 07:01 |
| Arafangion | Well, if it were working, it'd be running on it. :) | 07:02 |
| Arafangion | Going to watch a movie. | 07:02 |
| Keybuk | heh | 07:04 |
| Keybuk | have fun | 07:04 |
| Keybuk | but those should give you some ideas to debug what the hell is goingon | 07:04 |
| Keybuk | if it's a kernel bug, I'm going to do a drive-by on some of the developers | 07:05 |
| Keybuk | I've had enough of those this month | 07:05 |
| Arafangion | It's a fairly recent kernel, too. :) | 07:14 |
| Arafangion | At least, it was very recent not long ago. | 07:14 |
| Keybuk | oh | 07:15 |
| Keybuk | I can guarantee my kernel is more recent than yours | 07:15 |
| Keybuk | I don't think the patch is embargo'd until tomorrow :p | 07:15 |
| Keybuk | it turns out that upstart's test suite doubles as a proof-of-concept kernel exploit | 07:15 |
| Arafangion | Interesting. | 07:21 |
| Arafangion | Though, "recent"ness is a flexible concept. | 07:22 |
| Arafangion | At the time I built the system, the kernel had been out for... several minutes. ;) | 07:22 |
| Arafangion | Anyway, Stargate time! | 07:22 |

| Mogliii | hello, is anyone here who could tell me how to use grub in ubuntu 7.10 to boot into a certain runlevel, lets say 3 | 09:54 |
| Mogliii | Default is 2, but appending a 3 in the grub menu item, does not help... Guess its due to upstart | 09:55 |
| Mogliii | hello, is anyone here who could tell me how to use grub in ubuntu 7.10 to boot into a certain runlevel, lets say 3 | 10:02 |
| Mogliii | Default is 2, but appending a 3 in the grub menu item, does not help... Guess its due to upstart | 10:02 |
| Jc2k | Mogliii: a bit of googling suggests: | 10:07 |
| Jc2k | kernel /boot/vmlinuz-2.6.17-11-386 root=/dev/sda1 ro quiet splash runlevel=3 | 10:07 |
| Jc2k | is that the syntax you were using? | 10:08 |
| Mogliii | no, I used "/boot/vmlinuz-2.6.17-11-386 root=/dev/sda1 ro quiet splash 3" | 10:08 |
| Jc2k | can you try it with runlevel=3 then :) | 10:08 |
| Mogliii | ok, I will. Guess I am not the only one with that problem... https://launchpad.net/ubuntu/+source/upstart/+bug/85014 | 10:09 |
| Jc2k | ahh | 10:10 |
| Jc2k | the page i found was in spanish but had a similar script | 10:10 |
| Mogliii | So I will be gone for 5-10 minutes. Have to try it. Will check back again... | 10:10 |
| Jc2k | Mogliii: wait a sec | 10:10 |
| Mogliii | ok... | 10:10 |
| Jc2k | you will need a workaround script.. | 10:11 |
| Jc2k | this is the page that suggested runlevel=3... | 10:12 |
| Jc2k | http://www.xinug.org/drupal/upstart-runlevel-boot-time | 10:12 |
| Jc2k | but i can't figure any of the other bits out.. | 10:12 |
| Jc2k | you might be better waiting for one of devs, im just a lurker :) | 10:12 |
| Mogliii | ok, so it does not work with runlevel=3 on ubuntu 7.10. Thats a good thing, so the problem is not with me :) | 10:14 |
| Mogliii | Thank you | 10:14 |

| Mogliii | any developer online? | 13:05 |
| Keybuk | Mogliii: hello | 13:28 |
| Mogliii | hi, are you an upstart developer? | 13:30 |
| Keybuk | yes | 13:30 |
| Mogliii | I am not sure if you saw the stuff further up, but I am having trouble with passing a runlevel via grub | 13:30 |
| Mogliii | What I want to do is to have an entry in grub to start in runlevel 3. I want to execute a backup script and shutdown afterwards. | 13:31 |
| Mogliii | So to backup I only have to choose an entry and can go to sleep... | 13:31 |
| Keybuk | you were given the answer above | 13:31 |
| Mogliii | you mean with that workaround script? | 13:31 |
| Keybuk | right | 13:31 |
| Keybuk | and you found the bug that says you can't do it | 13:31 |
| Mogliii | will there ever be a clean solution for this? | 13:32 |
| Keybuk | yes, that's why there's a bug open | 13:32 |
| Mogliii | but for longer than march... Ok, I will try to understand how to implement the script... | 13:32 |
| Mogliii | Thank you for your time! | 13:35 |
| mojo__ | Keybuk: it's me again | 14:14 |
| mojo__ | Keybuk: does upstart relates to shutdown process? | 14:14 |
| Keybuk | it does the shutdown process, yes | 14:14 |
| mojo__ | Keybuk: is there anyway to know if the system reach the safe point ("System now halted") so I can press Power button? | 14:14 |
| mojo__ | Keybuk: my machine will not have Monitor | 14:15 |
| Keybuk | it should say it on the console | 14:15 |
| mojo__ | Keybuk: the fact I am designing a media player w/o Console or monitor | 14:15 |
| mojo__ | Keybuk: only the LCD screen | 14:15 |
| Keybuk | can it not power itself off? | 14:15 |
| mojo__ | Keybuk: small 20x4 dot matrix Matrix Orbital one | 14:15 |
| mojo__ | Keybuk: no | 14:15 |
| Keybuk | how come? that seems to be a bug :) | 14:16 |
| mojo__ | Keybuk: the fact LCD daemon killed by then so I can't show the output that system is now safe to turn off | 14:16 |
| mojo__ | Keybuk: heh? | 14:16 |
| mojo__ | Keybuk: really | 14:16 |
| Keybuk | well, most hardware can power itself off now | 14:16 |
| mojo__ | Keybuk: i compile ACPI, APM | 14:16 |
| mojo__ | Keybuk: i am using VIA EPA EN12000EG, not power off at all | 14:16 |
| Keybuk | did you try shutdown -h -P ? | 14:17 |
| mojo__ | let me try | 14:18 |
| mojo__ | said time expected | 14:18 |
| mojo__ | okat | 14:18 |
| mojo__ | shutdown -h -P now | 14:18 |
| mojo__ | works | 14:18 |
| mojo__ | waiting for it shutting down | 14:19 |
| mojo__ | hmm | 14:19 |
| mojo__ | no auto poweroff | 14:19 |
| mojo__ | it said System Halted | 14:19 |
| Keybuk | ok | 14:21 |
| Keybuk | I guess you'll need to patch the kernel to notify you in some other useful way | 14:21 |
| Keybuk | (the System Halted message comes from the kernel) | 14:21 |
| mojo__ | k | 14:22 |
| mojo__ | Keybuk: so... what do i need to debug? | 14:22 |
| Keybuk | I have no idea :-) | 14:23 |
| mojo__ | Keybuk: then know any can help me out here? | 14:24 |
| Keybuk | kernel developers | 14:24 |
| mojo__ | any specific channel for that? | 14:25 |
| Keybuk | no idea | 14:25 |
| mojo__ | Keybuk: fixed | 14:31 |
| mojo__ | Keybuk: thx, i append acpi=force to the kernel in menu.lst of grub | 14:31 |
| JohnFlux | Yo. | 15:19 |
| JohnFlux | :) | 15:19 |
| JohnFlux | Just want to poke people for adding a dbus interface to upstart :) | 15:19 |
| JohnFlux | s/for adding/to add/ | 15:20 |
| Keybuk | I already have one | 15:21 |
| JohnFlux | hmm, it's already been added? | 15:22 |
| JohnFlux | Keybuk: any idea which version of upstart? | 15:23 |
| Keybuk | not in a released version | 15:24 |
| JohnFlux | Keybuk: but it should be in the next released version? | 15:28 |
| Keybuk | yes | 15:28 |
| Keybuk | 0.5.0 will be d-bus based | 15:28 |
| JohnFlux | Keybuk: what happened to 0.4 ? | 15:31 |
| Keybuk | there is no 0.4 | 15:32 |
