7.5.6

Version 7.5.6 [devel] 2013-10-29

• improved performance of RainerScript variable access
  by refactoring the whole body of variable handling code. This also
  solves some of the anomalies experienced in some versions of rsyslog.
  All variable types are now handled in unified code, including
  access via templates.
• RainerScript: make use of 64 bit for numbers where available
  Thanks to Pavel Levshin for enhancement.
• slight performance optimization if GCC is used
  We give branch prediction hints for the frequent RETiRet macro which is
  used for error handling. Some slight performance gain is to be expected
  from that.
• removed global variable support
  The original idea was not well thought out and global variables, as
  implemented, worked far different from what anybody would expect. As
  such, we consider the current approach as an experiment that did not
  work out and opt to removing it, clearing the way for a better future
  solution. Note: global vars were introduced in 7.5.3 on Sept, 11th 2013.
• new module mmsequence, primarily used for action load balancing
  Thanks to Pavel Levshin for contributing this module.
• bugfix: unset statement always worked on message var, even if local
  var was given
• bugfix: segfault if variable was assigned to non-container subtree
  Thanks to Pavel Levshin for the fix
• bugfix: imuxsock did not suport addtl sockets if syssock was disabled
  Thanks to Pavel Levshin for the fix
• bugfix: running imupd on multiple threads lead to segfault if recvmmsg
  is available
• bugfix: segfault if re_extract() function was used and no match found
• bugfix: omelasticsearch did not compile on platforms without atomic
  instructions
• bugfix: potential misadressing on startup if property-filter was used
  This could happen if the property name was longer than 127 chars, a case
  that would not happen in practice.
• bugfix: invalid property filter was not properly disabled in ruleset
  Note: the cosmetic memory leak introduced with that patch in 7.4.5 is
  now also fixed.
