| temoto | Upstart runs all "start on runlevel 2" scripts in paralel? | 22:36 |
|---|---|---|
| damjan | yes | 22:38 |
| Zeqadious | damjan: you ever get around to toying with those arch upstart scripts? | 22:40 |
| damjan | Zeqadious: I've made my first successfull boot of Upstart on ArchLinux | 22:40 |
| Zeqadious | ah | 22:41 |
| damjan | I'm starting /etc/rc.sysinit and rc.multi now | 22:41 |
| Zeqadious | i know you were interested in 0.5 versions: http://zeqadious.homelinux.net/junkbin/upstart-0.5.1-jobs/ | 22:41 |
| Zeqadious | if it helps | 22:41 |
| damjan | so that I'm compatible with Arch as it is | 22:41 |
| Zeqadious | again based directly from Arch | 22:41 |
| temoto | damjan: that's awesome, thank you. | 22:42 |
| damjan | Zeqadious: I also made a multi-instance agetty script | 22:42 |
| Zeqadious | damjan: i would interested in seeing that :) | 22:43 |
| damjan | so basically, instead of having a separate script for each tty | 22:43 |
| Zeqadious | i tried to write a arch stype stat_busy stat_done stuff for upstart, but its quite flakey | 22:43 |
| Zeqadious | oh thats cool | 22:43 |
| temoto | start on stopped sysinit/kernel-logger RESULT=ok <- how does it work? | 22:44 |
| damjan | I have one, instance $TTY; exec /sbin/agetty -8 38400 $TTY linux | 22:44 |
| damjan | Zeqadious: and I have another script that starts all of the instances when rc.multi is stopped | 22:45 |
| damjan | temoto: sysinit/kernel-logger is a job | 22:45 |
| temoto | damjan: sorry, i mean "RESULT=ok" | 22:45 |
| damjan | when it's stopped (i.e. successfully run) your other script will run then | 22:45 |
| Zeqadious | if kernel-logger exits with status=1 it won't | 22:45 |
| temoto | exitcode? | 22:46 |
| damjan | temoto: each Unix process has a return value | 22:46 |
| temoto | aha | 22:46 |
| damjan | yeah like ecitcode | 22:46 |
| temoto | thanks, now i get it | 22:46 |
| temoto | errorlevel on windows | 22:46 |
| iamthelostboy | hi.. i have a upstart job getting started by an application emitting an event.. it is mostly working, except that upstart isnt terminating as I would expect.. i have cut the job down to a single 'exec xinit <app> <params>' | 22:46 |
| temoto | RESULT=ok and RESULT=0 is same? | 22:47 |
| damjan | Zeqadious: http://www.netsplit.com/2008/04/19/upstart-05-job-lifetime/ .. about instances | 22:47 |
| temoto | My ubuntu 9.04 has upstart 0.3.9 .. wow, i did expect something newer. | 22:48 |
| Zeqadious | damjan: nice stuff | 22:48 |
| temoto | damjan: are you developer of upstart? | 22:49 |
| damjan | temoto: no | 22:49 |
| damjan | far from it :) | 22:50 |
| Zeqadious | thats Scott's blog | 22:50 |
| damjan | Zeqadious: so these jobs you have, this is a port from rc.sysinit right? | 22:50 |
| Zeqadious | yes | 22:51 |
| damjan | k | 22:51 |
| Zeqadious | i have upstart job scripts for dbus, acpid, hal, networkmanager, crond, and syslog-ng too | 22:51 |
| Zeqadious | so far* | 22:51 |
| Zeqadious | they are ... problematic | 22:51 |
| temoto | I have two for memcacheq and mongodb :) | 22:52 |
| temoto | Zeqadious: what's problematic in crond or syslog? | 22:53 |
| Zeqadious | temoto: those seem to work 100%, however the others tend to not honor the start on stanza rules | 22:53 |
| temoto | Zeqadious: you mean tens of "and stopped" ? | 22:54 |
| Zeqadious | damjan: here is my 'current in use scripts' however they aren't quite compatable with Arch Linux anymore. But please feal to free to steal if you like anything http://zeqadious.homelinux.net/zizzy-linux/i686/abs/core/upstart-jobs/ | 22:54 |
| damjan | I need to do the shutdown part... couldn't find much documentation about it for Upstart | 22:57 |
| Zeqadious | i have problems because my data partition is always in use and can't be unmounted | 22:58 |
| Zeqadious | lol | 22:58 |
| Zeqadious | the command 'reboot' works 100% | 22:58 |
| Zeqadious | ctrl+alt+delete 0% | 22:58 |
| temoto | So on ubuntu using upstart 0.3.9 i can create directories, not only job files? upstart runs like /etc/event.d/*/* ? | 22:59 |
| damjan | yes | 22:59 |
| temoto | cool | 22:59 |
| temoto | start on RESULT=failed now what this mean? | 22:59 |
| damjan | when exitcode is not 0 | 22:59 |
| temoto | RESULT of what? | 22:59 |
| Zeqadious | anything | 23:00 |
| temoto | uh | 23:00 |
| temoto | any other upstart job? | 23:00 |
| Zeqadious | yes | 23:00 |
| temoto | Zeqadious: it's your jobs.d/sulogin | 23:00 |
| Zeqadious | temoto: i'm aware | 23:01 |
| temoto | hm.. if anything fails - sulogin. | 23:02 |
| temoto | What if /sbin is not mounted - then sulogin job fails and upstart runs another one? | 23:02 |
| damjan | temoto: if /sbin is not mounted, upstart will not start either | 23:03 |
| Zeqadious | lol | 23:03 |
| temoto | right | 23:03 |
| temoto | But what if /sbin would be unmounted after upstart starts? | 23:04 |
| temoto | ..and anything fails | 23:04 |
| Zeqadious | system required boot files reside in /{bin,sbin,lib,etc} per fhs. they are required to be there for boot. | 23:05 |
| damjan | temoto: upstart (and sysvinit) are /sbin/init, can't be umounted | 23:05 |
| temoto | fs can't be unmounted while program started from it is running? | 23:06 |
| Zeqadious | temoto: /usr, /var, and /home are often on other partitions however | 23:06 |
| damjan | temoto: yes, it can't | 23:07 |
| temoto | hm.. all this start on stopped this and stopped that.. it's possible (and Zeqadious did) to build a complex dependancy tree. | 23:09 |
| temoto | But it's very hard to see this dependancies with just browsing files. | 23:10 |
| temoto | There must be some kind of sysv-rc-conf program to manage jobs via UI. | 23:10 |
| damjan | yeah it can be hard to debug | 23:11 |
| Zeqadious | as the dev's of most projects seem fond of saying, "patches welcome" | 23:11 |
| Zeqadious | :) | 23:11 |
| damjan | a simple tool showing the dependency tree would be nice | 23:11 |
| temoto | so not yet? | 23:11 |
| Zeqadious | temoto: not that i'm aware | 23:11 |
| temoto | i see | 23:11 |
| Zeqadious | my scripts certainly aren't 100% yet anyway. closer to 70% and rough. | 23:12 |
| Zeqadious | the status messages are very* problematic because of the parallel jobs :) | 23:12 |
| temoto | Zeqadious: btw in one your job file i saw you put \ at the end of lines in 'start on' stanza. In other job i see no \. | 23:13 |
| Zeqadious | see previous line. | 23:13 |
| temoto | Zeqadious: so that's syntax error? | 23:14 |
| Zeqadious | technically yes, but it will still work. | 23:14 |
| temoto | erh..? | 23:15 |
| temoto | I think they 100% must not require \, that would make jobs readable. | 23:15 |
| Zeqadious | damjan: do you happen to know if the environment jobs run in is 100% posix compliant (eg. dash) or the regular 100% posix based (eg. bash)? | 23:21 |
| Zeqadious | damjan: i get the feeling from working on this for a while that its probably /bin/sh | 23:21 |
| damjan | I don't know | 23:22 |
| Zeqadious | oh well | 23:22 |
| temoto | Zeqadious: > script instead gives shell script code that will be executed using /bin/sh | 23:22 |
| damjan | I think I've read somewhere about the implementation of script, but that was long time ago | 23:22 |
| temoto | http://upstart.ubuntu.com/getting-started.html | 23:22 |
| Zeqadious | at least for version 0.3.9 anyway | 23:24 |
| Zeqadious | probably still the same however. | 23:24 |
| damjan | paths.h:#define SHELL "/bin/sh" | 23:25 |
| Zeqadious | nice | 23:25 |
