| Keybuk | sadmac: Bill is using emit in a very strange way in #435368 | 16:04 |
|---|---|---|
| sadmac_ | Keybuk: what's the issue? | 16:47 |
| Keybuk | is it just a minimal test case that demonstrates the bug? | 16:50 |
| Keybuk | ie. why are you using emit? | 16:50 |
| sadmac_ | exactly, just a test case | 16:50 |
| sadmac_ | the point is a job started by an event with arguments doesn't get those arguments again when restarted | 16:50 |
| Keybuk | true... | 16:53 |
| Keybuk | but since events don't even *have* arguments anymore in trunk | 16:53 |
| Keybuk | and even while they still did, they weren't passed to the job anyway ... | 16:54 |
| Keybuk | it's kinda a null test case :p | 16:54 |
| Keybuk | it's certainly a bug in 0.3 that the associated event information is lost for services once they're running, so not available after the respawn - that is fixed in trunk | 16:54 |
| sadmac_ | Ah cool | 16:57 |
| Keybuk | the trunk equivalent would be something like: | 16:57 |
| Keybuk | initctl emit foo DEV=bar PATH=baz | 16:58 |
| Keybuk | and then you'd use $DEV and $PATH in the script | 16:58 |
| Keybuk | and they survive respawn | 16:58 |
| Keybuk | until a different event starts the job | 16:58 |
| Keybuk | or you change them with start | 16:58 |
| Keybuk | ie. | 16:58 |
| Keybuk | initctl start jobname DEV=wibble PATH=wobble | 16:58 |
| sadmac_ | cool | 16:59 |
| sadmac_ | Keybuk: have you had any thoughts on lod and making it work? | 17:00 |
| Keybuk | lod? | 17:00 |
| sadmac_ | s/lod/logd/ | 17:00 |
| Keybuk | not really | 17:01 |
| Keybuk | the only thing I've come up with would be making logd have a pty | 17:01 |
| Keybuk | and telling upstart to divert output from jobs to that pty while running | 17:01 |
| Keybuk | that doesn't fix logd dying though | 17:01 |
| Keybuk | so has the same basic problems as the socket | 17:02 |
| sadmac_ | hm | 17:02 |
| sadmac_ | Keybuk: you could have upstart itself hold a pipe to each program, and then just bridge it through sunrpc to logd (since sunrpc has that lovely property of just sitting and buffering when the listener goes away) | 17:03 |
| Keybuk | interesting | 17:03 |
| Keybuk | would you need the bridge in that instance? | 17:04 |
| sadmac_ | the one big limitation of sunrpc is it has a custom interface (no file descriptors) so you can't just bolt it right onto stdio | 17:04 |
| sadmac_ | so yes | 17:04 |
| Keybuk | ah | 17:04 |
| sadmac_ | oh, not sunrpc | 17:04 |
| sadmac_ | sunipc | 17:05 |
| sadmac_ | or sun ipc | 17:05 |
| Keybuk | lol | 17:05 |
| Keybuk | the problem with the bootlogd approach, btw (stealing console output via ioctl) is it doesn't work with our usplash | 17:05 |
| Keybuk | and I suspect it wouldn't work with your X rhgb either | 17:06 |
| Keybuk | since both *change* the console to be a graphical one, with text diverted elsewhere | 17:06 |
| sadmac_ | you could alter usplash of course. (I may rewrite rhgb once we get off the ground. right now I'm patching some stuff into upstart to deal with it) | 17:07 |
| Keybuk | it isn't usplash that's the problem | 17:08 |
| Keybuk | it's svgalib | 17:08 |
| Keybuk | and I want to fiddle with that about as much as I want to wake up without my kidneys | 17:08 |
| sadmac_ | ah | 17:09 |
| sadmac_ | Keybuk: it looked like in trunk the event files had moved, is this the case? | 17:20 |
| Keybuk | event files? | 17:21 |
| sadmac_ | /etc/event.d/* | 17:21 |
| Keybuk | possibly moving to /etc/init/jobs.d | 17:23 |
| sadmac_ | yeah, any particular reason? | 17:23 |
| Keybuk | to stop people calling them "event files" :) | 17:24 |
| Keybuk | since they're not | 17:24 |
| Keybuk | they're job files | 17:24 |
| Keybuk | jobs and events are different things | 17:24 |
| Keybuk | but everyone confuses the two because of the directory name | 17:24 |
| sadmac_ | ah. | 17:24 |
| Keybuk | e.g. people think that if you have /etc/event.d/foo | 17:26 |
| Keybuk | then initctl emit foo will start it | 17:27 |
| sadmac_ | yeah. | 17:27 |
| Keybuk | which isn't true at all | 17:28 |
| sadmac_ | Keybuk: one more correction, it wasn't sun ipc. it was sysv. | 17:32 |
| * sadmac_ should drink coffee while reading things | 17:32 | |
| sadmac_ | specifically message queues | 17:34 |
