Version 7.2.7 [v7-stable] 2013-04-17
- rsyslogd startup information is now properly conveyed back to init
when privileges are beging dropped
Actually, we have moved termination of the parent in front of the
priv drop. So it shall work now in all cases. See code comments in
commit for more details.
- If forking, the parent now waits for a maximum of 60 seconds for
termination by the child
- improved debugging support in forked (auto-backgrounding) mode
The rsyslog debug log file is now continued to be written across the
- updated systemd files to match current systemd source
- bugfix: failover/action suspend did not work correctly
This was experienced if the retry action took more than one second
to complete. For suspending, a cached timestamp was used, and if the
retry took longer, that timestamp was already in the past. As a
result, the action never was kept in suspended state, and as such
no failover happened. The suspend functionalit now does no longer use
the cached timestamp (should not have any performance implication, as
action suspend occurs very infrequently).
- bugfix: nested if/prifilt conditions did not work properly
- bugfix: script == comparison did not work properly on JSON objects
[backport from 7.3 branch]
- bugfix: imudp scheduling parameters did affect main thread, not imudp

- bugfix: imuxsock was missing SysSock.ParseTrusted module parameter
To use that functionality, legacy rsyslog.conf syntax had to be used.
Also, the doc was missing information on the “ParseTrusted” set of
- bugfix: parameter action.execOnlyWhenPreviousIsSuspended was accidently
of integer-type. For obvious reasons, it needs to be boolean. Note
that this change can break existing configurations if they circumvented
the problem by using 0/1 values.
- doc bugfix: rsyslog.conf man page had invalid file format info
