| frew | hey guys | 17:09 |
|---|---|---|
| frew | I'm using post-start to block until a service is ready | 17:09 |
| frew | I was under the impression that if a post-start script exits non-zero the service will then stop | 17:10 |
| frew | but I guess that's not documented to be the case, and maybe it just isn't | 17:10 |
| frew | thoughts? | 17:10 |
| chras | frew: dont you want that in pre-start? | 17:31 |
| frew | uh | 18:15 |
| frew | no I don't see how that would make sense | 18:15 |
| frew | I want to run the main script, and then block till it's ready | 18:16 |
| chras | maybe im confused whatyou're trying to do | 18:17 |
| frew | yeah sorry | 18:17 |
| frew | so like | 18:17 |
| frew | imagine you have a web server | 18:17 |
| frew | and it takes like, 10s before it actually listens on port 80 | 18:17 |
| chras | becuase you have some sort of ruby , or whatnot that takes time to do the initial compile? | 18:18 |
| frew | you can add a post-start that wget's port 80 over and over till it gets an actual return | 18:18 |
| frew | right exactly | 18:18 |
| frew | the problem is | 18:18 |
| frew | I'd like the post-start script, if it takes to long, to give up and mark the whole thing as failed | 18:18 |
| chras | does something else trigger off of this event? | 18:20 |
| frew | well | 18:30 |
| frew | if you do start $foo | 18:30 |
| frew | it will block until post-start completes | 18:30 |
| frew | so naive scripts do indeed | 18:30 |
| chras | frew: i just tested, and an exit code of 1 in a post-stop doesnt kill the already-running process | 18:31 |
| chras | but | 18:31 |
| frew | yeah I know; I just want it to :) | 18:31 |
| chras | if you manually check | 18:32 |
| chras | and issue a 'stop' inside your post-start | 18:32 |
| chras | then it will shut it down | 18:32 |
| frew | I thought I tried that | 18:33 |
| frew | how do you do that? I tried literally stop $svcname | 18:33 |
| chras | so in my test i did this | 18:33 |
| chras | post-start script echo "sysrqd: this is a post start the next line is a stop" | $ILOG stop | 18:33 |
| chras | oop, formatting is wrong | 18:33 |
| chras | ill pastebin it | 18:33 |
| chras | https://pastebin.mozilla.org/8869640 | 18:33 |
| frew | ok just a single stop. | 18:34 |
| frew | huh | 18:34 |
| chras | yeah | 18:34 |
| frew | any idea if that will make start exit non-zero? | 18:34 |
| frew | not a huge deal but that would be nice | 18:34 |
| chras | i think it just sends a term to the process | 18:34 |
| chras | at least, thats what it appears to do | 18:35 |
| frew | right. | 18:35 |
