bugfix

Version 8.6.0 [v8-stable] 2014-12-02
NOTE: This version also incorporates all changes and enhancements made for
v8.5.0, but in a stable release. For details see immediately below.

• configuration-setting rsyslogd command line options deprecated
  For most of them, there are now proper configuration objects. Some few will be completely dropped if nobody insists on them.  Additional info at
  http://blog.gerhards.net/2014/11/phasing-out-legacy-command-line-options.html
• new and enhanced plugins for 0mq. These are currently experimantal.
  Thanks to Brian Knox who contributed the modules and is their author.
• empty rulesets have been permitted. They no longer raise a syntax error.
• add parameter -N3 to enable config check of partial config file
  Use for config include files. Disables checking if any action exists at
  all.
• rsyslogd -e option has finally been removed
  It is deprectated since many years.
• testbench improvements
  Testbench is now more robust and has additional tests.
• testbench is now by default disabled
  To enable it, use –enable-testbench. This was done as the testbench now does better checking if required modules are present and this in turn would lead to configure error messages where non previously were if we would leave –enable-testbench on by default. Thus we have turned it off. This should not be an issue for those few testbench users.
• add new RainerScript functions warp() and replace()
  Thanks to Singh Janmejay for the patch.
• mmnormalize can now also work on a variable
  Thanks to Singh Janmejay for the patch.
• new property date options for day ordinal and week number
  Thanks to github user arrjay for the patch
• remove –enable-zlib configure option, we always require it
  It’s hard to envision a system without zlib, so we turn this off
  closes https://github.com/rsyslog/rsyslog/issues/76
• slight source-tree restructuring: contributed modules are now in their own ./contrib directory. The idea is to make it clearer to the end user which plugins are supported by the rsyslog project (those in ./plugins).
• bugfix: imudp makes rsyslog hang on shutdown when more than 1 thread used
  closes https://github.com/rsyslog/rsyslog/issues/126
• bugfix: not all files closed on auto-backgrounding startup
  This could happen when not running under systemd. Some low-numbered fds were not closed in that case.
• bugfix: typo in queue configuration parameter made parameter unusable
  Thanks to Bojan Smojver for the patch.
• bugfix: unitialized buffer off-by-one error in hostname generation
  The DNS cache used uninitialized memory, which could lead to invalid hostname generation.
  Thanks to Jarrod Sayers for alerting us and provinding analysis and patch recommendations.
• bugfix imuxsock: possible segfault when SysSock.Use=”off”
  Thanks to alexjfisher for reporting this issue.
  closes https://github.com/rsyslog/rsyslog/issues/140
• bugfix: RainerScript: invalid ruleset names were accepted during ruleset defintion, but could of course not be used when e.g. calling a ruleset.
  IMPORTANT: this may cause existing configurations to error out on start, as they invalid names could also be used e.g. when assigning rulesets.
• bugfix: some module entry points were not called for all modules callbacks like endCnfLoad() were primarily being called for input modules. This has been corrected. Note that this bugfix has some regression potential.
• bugfix omlibdbi: connection was taken down in wrong thread
  This could have consequences depending on the driver being used. In general, it looks more like a cosmetic issue. For example, with MySQL it lead to a small memory but also an annoying message about a thread not properly torn down.
• imttcp was removed because it was an incompleted experimental module
• pmrfc3164sd because it was a custom module nobody used
  We used to keep this as a sample inside the tree, but whoever wants to look at it can check in older versions inside git
• omoracle was removed because it was orphaned and did not build/work for quite some years and nobody was interested in fixing it
