Version 3.12.4 (rgerhards), 2008-03-25
Greatly enhanced rsyslogd's file write performance by disabling
file syncing capability of output modules by default. This
feature is usually not required, not useful and an extreme performance
hit (both to rsyslogd as well as the system at large). Unfortunately,
most users enable it by default, because it was most intuitive to enable
it in plain old sysklogd syslog.conf format. There is now the
$ActionFileEnableSync config setting which must be enabled in order to
support syncing. By default it is off. So even if the old-format config
lines request syncing, it is not done unless explicitely enabled. I am
sure this is a very useful change and not a risk at all. I need to think
if I undo it under compatibility mode, but currently this does not
happen (I fear a lot of lazy users will run rsyslogd in compatibility
mode, again bringing up this performance problem...).
added flow control options to other input sources
added $HHOUR and $QHOUR system properties - can be used for half- and
quarter-hour logfile rotation
changed queue's discard severities default value to 8 (do not discard)
to prevent unintentional message loss
removed a no-longer needed callback from the output module
interface. Results in reduced code complexity.
bugfix/doc: removed no longer supported -h option from man page

the patch
