Last week there was much discussion (some of it even on topic :) about
making multilog rotate files on receipt of a signal.
Here's my very simple patch to make multilog rotate its current file
on receipt of SIGHUP. I have tested it under RedHat Linux 6.2 ONLY.
However, as I have used Dan's coding style (all 2 lines of it) it
should work under any systems on which multilog currently works.
My tests were fairly minimal - I hammered multilog as fast as I could
and sent it a SIGHUP. I then checked to see if it lost any data
between rotations - it didn't.
It obviously needs field testing, but I think it will allow us to
rotate based on time. All we need is a cron job to send the SIGHUP at
the appropriate time.
If you use this, please let me know how it goes. If I get positive
feedback (or no feedback at all) I'll release it in the same manner as
my tai64nunix package - ie a stripped down daemontools with only enough
to build the new multilog. This should comply with Dan's licensing
rules.
