| toidinamai | Hello. | 05:43 |
|---|---|---|
| toidinamai | How does upstart compare with runit or djb's daemontools? | 05:43 |
| === toidinamai [n=frank@i59F72BC0.versanet.de] has joined #upstart | ||
| Jc2k | toidinamai: i am in no way even close to an expert on the subject, but runit seems very minimalist in comparison to upstart | 10:20 |
| Jc2k | thats not meant to say that upstart is fat, just that it has a larger scope | 10:21 |
| Jc2k | i can't see that daemontools even tries to replace init, so that would be the difference there | 10:22 |
| Jc2k | my understanding is that upstart tries to be a really flexible event based service manager | 10:23 |
| Jc2k | so you can configure a service or job to run each time a service is starting, started, stopping or stopped | 10:24 |
| Jc2k | but also on a time event | 10:24 |
| Jc2k | or even on a HAL event | 10:24 |
| Jc2k | runit and daemontools just seem concerned with getting things started or stopped, and your left to handle dependencies in your scripts rather than taking advantage of a ready made dependency handler | 10:25 |
| Jc2k | toidinamai: the best guy to answer your question is probably Keybuk | 10:26 |
| Jc2k | he's on UK time if that helps you plan when best to come on IRC (04:43AM is a little early for us brits ;D) | 10:27 |

| toidinamai | Keybuk: Does upstart supervise its services like daemontools or runit? | 02:21 |
| Keybuk | hello | 02:21 |
| Keybuk | err | 02:21 |
| Keybuk | Upstart supervises services, so can respawn them if they die | 02:22 |
| Keybuk | I don't know whether it supervises them in the same way as daemontools or runit though | 02:22 |
| Keybuk | (but maybe you didn't intend to ask that) | 02:22 |
| toidinamai | Hm, I guess I'll just have to try it out. | 02:23 |
| toidinamai | I'm currently using runit as an init replacement everywhere I can but it still needs a lot of fine tuning. | 02:24 |
| Keybuk | I can probably answer specific questions in quite detail | 02:24 |
| Keybuk | though I don't know how the other tools behave | 02:25 |
| toidinamai | Ok. | 02:25 |
| toidinamai | So upstart doesn't use the traditional init scripts at all, is that right? | 02:25 |
| Keybuk | right | 02:26 |
| toidinamai | How does it deal with scripts installed by packages like openssh-server? | 02:26 |
| Keybuk | what kind of scripts? | 02:27 |
| toidinamai | /etc/init.d/ssh | 02:27 |
| Keybuk | it ignores them completely | 02:27 |
| Keybuk | the usual way you install Upstart is to have Upstart jobs emulate the lines in your old inittab | 02:28 |
| Keybuk | (running /etc/init.d/rc, or whatever) | 02:28 |
| Keybuk | so existing init scripts are run by the existing sysvinit scripts, etc. | 02:28 |
| Keybuk | leaving you free to convert over to Upstart jobs at your leisure | 02:28 |
| Keybuk | obviously you don't get any kind of supervision for legacy init scripts | 02:28 |
| toidinamai | Hm. I sometimes get conflicts that way when using runit. After installing a server package dpkg adds it to the runlevels and tries to start it. | 02:31 |
| toidinamai | Upstart uses traditional logging using syslog, right? | 02:43 |

| ion_ | Another guy got valgrind to segfault just a while ago. | 07:45 |
| Keybuk | valgrind usually segfaults because your program does | 07:48 |
| ion_ | Well, it spewed an error like valgrind: the impossible happened first. :-) | 07:48 |
