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 - bugfix: imklog leaked several hundered KB on each HUP.
