8.16.0

——————————————————————————
Version 8.16.0 [v8-stable] 2016-01-26

• rsgtutil: Added extraction support including loglines and hash chains.
  More details on how to extract loglines can be found in the rsgtutil
  manpage. See also: https://github.com/rsyslog/rsyslog/issues/561
• clean up doAction output module interface
  We started with char * pointers, but used different types of pointers
  over time. This lead to alignment warnings. In practice, I think this
  should never cause any problems (at least there have been no reports
  in the 7 or so years we do this), but it is not clean. The interface is
  now cleaned up. We do this in a way that does not require modifications
  to modules that just use string parameters. For those with message
  parameters, have a look at e.g. mmutf8fix to see how easy the
  required change is.
• new system properties for $NOW properties based on UTC
  This permits to express current system time in UTC.

• impstats: support broken ElasticSearch JSON implementation
  ES 2.0 no longer supports valid JSON and disallows dots inside names.
  This adds a new “json-elasticsearch” format option which replaces
  those dots by the bang (“!”) character. So “discarded.full” becomes
  “discarded!full”.
  This is a workaroud. A method that will provide more control over
  replacements will be implemented some time in the future. For
  details, see below-quoted issue tracker.

• omelasticsearch: craft better URLs
  Elasticsearch is confused by url’s ending in a bare ‘?’ or ‘&’. While
  this is valid, those are no longer produced.
  Thanks to Benno Evers for the patch.
• imfile: add experimental “reopenOnTruncate” parameter
  Thanks to Matthew Wang for the patch.
• bugfix imfile: proper handling of inotify initialization failure
  Thanks to Zachary Zhao for the patch.
• bugfix imfile: potential segfault due to improper handling of ev var
  This occurs in inotify mode, only.
  Thanks to Zachary Zhao and Peter Portante for the patch.

• bugfix imfile: potential segfault under heavey load.
  This occurs in inotify mode when using wildcards, only.
  The root cause is dropped IN_IGNOPRED inotify events which be dropped
  in circumstance of high input pressure and frequent rotation, and
  according to wikipeida, they can also be dropped in other conditions.
  Thanks to Zachary Zhao for the patch.

• bugfix ommail: invalid handling of server response
  if that response was split into different read calls. Could lead to
  error-termination of send operation. Problem is pretty unlikely to
  occur in standard setups (requires slow connection to SMTP server).
  Thank to github user haixingood for the patch.
• bugfix omelasticsearch: custom serverport was ignored on some platforms
  Thanks to Benno Evers for the patch.
• bugfix: tarball did not include some testbench files
  Thanks to Thomas D. (whissi) for the patch.
• bugfix: memory misadressing during config parsing string template
  This occurred if an (invalid) template option larger than 63 characters
  was given.
  Thanks to git hub user c6226 for the patch.
• bugfix imzmq: memory leak
  Thanks to Jeremy Liang for the patch.
• bugfix imzmq: memory leak
  Thanks to github user xushengping for the patch.
• bugfix omzmq: memory leak
  Thanks to Jack Lin for the patch.
• some code improvement and cleanup
