| xnox | internetpanda: init-checkconf is your friend. But it looks like you should deltet line 98 and line 14, there is no need to wrap respawn/exec stanzas in "script... end script". | 07:54 |

| arthurdent | hey i'm trying to start a service with upstart (mdm) and the only output I get is "mdm stop/waiting" | 20:13 |
| arthurdent | mdm works fine if i just run it, but i can't figure out how to get more debug output from service or initctl or start | 20:14 |
| arthurdent | okay i figured out the problem | 20:42 |
| arthurdent | /etc/profile contained a line in it "source" but apparently upstart chokes if it's not "." | 20:42 |
| arthurdent | why is this? | 20:42 |
| arthurdent | obviously it's using sh instead of bash to source profile, but that seems dumb | 20:45 |
| MindQuad | your statement makes no sense | 20:46 |
| MindQuad | if it was something in /etc/profile it would fail on every upstart job | 20:46 |
| arthurdent | MindQuad: well it didn;t | 20:46 |
| MindQuad | arthurdent: then it's doubtful it's something in /etc/profile | 20:46 |
| MindQuad | a symptom as opposed to a cause | 20:46 |
| arthurdent | MindQuad: well | 20:49 |
| arthurdent | cat /var/log/upstart/mdm.log => /proc/self/fd/9: 31: /etc/profile source: not found | 20:49 |
| MindQuad | so ? | 20:49 |
| arthurdent | changing it to . fixed it, maybe a bunch of other stuff wasn't starting up either; it's not so obvious when your display manager isn't running | 20:49 |
| MindQuad | that's a specific upstart script - not upstart | 20:50 |
| MindQuad | thats the mdm script | 20:50 |
| arthurdent | it doesn't call sh anywhere in the script, it just uses . to source /etc/profile | 20:50 |
| MindQuad | s o? | 20:51 |
| arthurdent | so . executes commands in the current shell | 20:51 |
| MindQuad | that's a problem with a specific script, not upstart | 20:51 |
| arthurdent | how could only the mdm script be running in sh instead of bash? | 20:51 |
| MindQuad | who said anything about running sh ? | 20:51 |
| arthurdent | why else would source not work? | 20:51 |
| MindQuad | tht's what you'd have to look at | 20:52 |
| MindQuad | but it's not an upstart problem | 20:52 |
| arthurdent | why are all of these other upstart scripts written for sh? | 20:54 |
| MindQuad | what are you talking about "sh" | 20:54 |
| MindQuad | why are you making that assumption | 20:54 |
| MindQuad | ls -la /bin/sh | 20:54 |
| MindQuad | on your system | 20:54 |
| arthurdent | /bin/sh -> dash | 20:54 |
| MindQuad | right | 20:54 |
| MindQuad | so it doesn't matter then, it's pointing at dash anyway | 20:54 |
| MindQuad | so why you are referencing bourne shell I have no idea | 20:55 |
| arthurdent | whatever then, so does upstart use dash? | 20:55 |
| MindQuad | if that's what the script is written with or the default shell of your init user | 20:55 |
| MindQuad | so again, this is a basic shell script failing for one service, which looking at the fact that it's mdm - suggests it's something specific to mint | 20:56 |
| MindQuad | so it's not an upstart problem, rather someone has made a scripting error with that script | 20:56 |
| MindQuad | so I'd talk to the mint maintainer and ask them to fix it | 20:56 |
| arthurdent | is dash not the default shell on ubuntu? | 20:58 |
| MindQuad | I think so yes | 20:58 |
| MindQuad | not sure why that matters though ? | 20:58 |
| MindQuad | or am I wrong that mdm is the mint service | 20:58 |
| MindQuad | I thought that was a mint supplied package, or am I wrong ? | 20:58 |
| arthurdent | no, you're correct | 20:59 |
| MindQuad | ok, so ubuntu's default shell doesn't matter then | 20:59 |
| MindQuad | and has no relecence | 20:59 |
| arthurdent | I was just wondering if it was a problem that would also occur on ubuntu if someone wrote a similar script. | 21:00 |
| MindQuad | if someone writes a bad shell script it will fail on eny distribution | 21:00 |
| MindQuad | so "yes" | 21:00 |
| MindQuad | but also the distribution has no importnce here, neither does upstart as someone has just written a bad shell script with a mistake | 21:01 |
| arthurdent | is the mistake trying to source /etc/profile from inside the script? | 21:01 |
| MindQuad | the mistake is someone has written a shell script with an invalid shell command for the shell you are using | 21:01 |
| arthurdent | no, i put that in /etc/profile. i had no idea the mdm upstart script was going to try to source it with dash | 21:02 |
| MindQuad | ok, so the problem is you have made a mistake, putting in an invalid command | 21:02 |
| MindQuad | remove the command and you're done | 21:02 |
| arthurdent | MindQuad: yeah i said that 15 minutes ago and you told me i was wrong | 21:02 |
| MindQuad | no, I thought you where saying the "source" command was in the init script | 21:03 |
| MindQuad | I miss-understood what you where saying | 21:03 |
| arthurdent | you're right, i should have said the upstart script chokes | 21:04 |
| arthurdent | and not assume it was upstart itself | 21:04 |
| arthurdent | was upstart around when gdm was still used | 21:05 |
| MindQuad | yes | 21:05 |
| MindQuad | well, I'm not sure when mint moved away from that atually, but I'd assume so | 21:05 |
| arthurdent | i meant on ubuntu, but yeah; i wonder how the script was written for gdm and if it had similar limitations | 21:06 |
| MindQuad | limitations ? | 21:06 |
| MindQuad | the limitation is you've put in an invalid command | 21:07 |
| MindQuad | how is that a limitation, it's just a scripting error | 21:07 |
| MindQuad | either way, this isn't anything to do with upstart, so it's not really for this channel,. | 21:07 |
| arthurdent | alright, well thanks for your support. i guess it's a scripting error because the distro i use sources stuff with bash and I didn't realise some distros still used dash | 21:08 |
| MindQuad | mint uses dash | 21:09 |
| MindQuad | so that's just poor maintenance / packaging | 21:09 |
| arthurdent | mint isn't my distro, i just have to support a bunch of computers that run it | 21:09 |
| MindQuad | oh, sorry, I thought it was mint because you where running mdm | 21:09 |
| MindQuad | why are you running mdm if it's not mint | 21:09 |
| MindQuad | actually - that's out of scope for this channel | 21:09 |
| MindQuad | sorry | 21:09 |
| arthurdent | alright, i'm gonna dip, but the answer to your question is that i'm maintaining mdm on about 150+ mint machines, but I don't use mint on my personal machine. | 21:10 |
| arthurdent | thanks again | 21:10 |
