Here's my latest attempt. I've defined
a script 's6-notifywhenup-fswatch':
========================================
#! /usr/bin/env execlineb -S0
multisubstitute
{
define EVENT U
define FIFODIR event
define FILE ready
define TIMEOUT 60000 # milliseconds
}
background -d
{
if { rm -f $FILE }
if { s6-maximumtime -t $TIMEOUT fswatch -1 $FILE } # any single event
on $FILE
s6-ftrig-notify $FIFODIR $EVENT
}
$@
========================================
Using mysqld for example, inside the 'run' script:
s6-notifywhenup-fswatch ... mysqld ...
And 'log/run':
s6-log ... -. "+mysqld: ready for connections\." ^0 =../ready ...
Seems to work reasonably well.
