Bug 89212 – metalog init.d script addition

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Max Loparev 2005-04-15 12:30:02 UTC]

I offer to add runtime switching of sync/async mode to init.d/metalog

opts="${opts} async sync"

async() {
        ebegin "Switching to async mode"
        kill -USR2 $(</var/run/metalog.pid)
        eend $?
}

sync() {
        ebegin "Switching to sync mode"
        kill -USR1 $(</var/run/metalog.pid)
        eend $?
}

that support is already in metalog ... the functions are 'buffer' and 'unbuffer'

can you write an example how i can use this functions from command line or point me to some doc about this?

ok just has emerged -u metalog but found that signals not conformed to the manual

README.gz >>

If you temporarely want to switch to the asynchronous mode, send an USR2
signal to the process. Something like :

kill -USR2 $(cat /var/run/metalog.pid)

should do the trick.

Later, if you want to watch activity in real-time (like a good old "tail -f"
on a log file), you can disable buffering. Just send an USR1 signal to the
"MASTER" process. You can always re-enable buffering afterwards.

swapped USR1 for USR2
