7.5.3

Version 7.5.3 [devel] 2013-09-11

• imfile: support for escaping LF characters added embedded LF in syslog messages cause a lot of trouble. imfile now has the capability to escape them to “#012″ (just like the regular control character escape option). This requires new-style input statements to be used. If legacy configuration statements are used, LF escaping is always turned off to preserve compatibility.
  NOTE: if input() statements were already used, there is a CHANGE OF BEHAVIOUR: starting with this version, escaping is enabled by default. So if you do not want it, you need to add escapeLF=”off” to the input statement. Given the trouble LFs cause and the fact that the majority of installations still use legacy config, we considered this behaviour change acceptable and useful.

• add support for global and local variables
• bugfix: queue file size was not correctly processed
  this could lead to using one queue file per message for sizes >2GiB
  Thanks to Tomas Heinrich for the patch.
• add main_queue() configuration object to configure main message queue
• bugfix: stream compression in imptcp caused timestamp to be corrupted
• imudp: add ability to specify SO_RCVBUF size (rcvbufSize parameter)
• imudp: use inputname for statistics, if configured
• impstats: add process resource usage counters [via getrusage()]
• impstats: add paramter “resetCounters” to report delta values possible for most, but not all, counters. See doc for details.
• librelp 1.2.0 is now required
• make use of new librelp generic error reporting facility
  This leads to more error messages being passed to the user and thus simplified troubleshooting.
• bugfix: very small memory leak in imrelp
  more or less cosmetic, a single memory block was not freed, but this only happens immediately before termination (when the OS automatically frees all memory). Still an annoyance e.g. in valgrind.
• fix compile problem in debug build
• imported fixes from 7.4.4
