DESCRIPTION:

  A new version of syslog-ng Open Source Edition (3.3.0beta2) has been
  released.

CHANGES:

3.3.0beta2
	Fri, 12 Aug 2011 09:00:17 +0200

	Highlights
	==========

	This release has started using the officially assigned port numbers
	for RFC5424 based log transports. syslog-ng will properly use the
	old defaults if the configuration @version indicates an old config.

	This release contains all identified bug fixes published by the
	BalaBit syslog-ng team in their syslog-ng PE 4.1 release, additional
	features will be integrated into syslog-ng 3.4 as 3.3 is already
	feature-frozen.  See more details on the list of bugs fixed in the
	"bugfixes" section below.

	This release got a "beta" tag instead of a "release-candidate"
	because of the level of public testing it has received.  However all
	currently known bugs are believed to be fixed and this should be
	much better than beta1 was.

	Bugfixes:
	=========
	* Fixed a memory leak in macro based destination files.

	* Fixed the "dropped" and "stored" counters for the SQL destination,
	  which were swapped previously.

	* Fixed file sources to properly start the source file from the
	  beginning when restoring the persistent state failed.

	* Fixed BSD timestamp parsing, that caused an extra syslog header to
	  be added to messages which had a single digit day-of-the-month
	  (e.g. the first ten days for every month).

	* Fixed a possible crasher at exit, caused by the destinations being
	  flushed and the associated sources already cleaned up.

	* Fixed a destination specific memory leak, which caused some
	  hundred bytes to be leaked when the configuration was reloaded.

	* Set O_CLOEXEC for child program pipes, in order to avoid
	  inheriting those to other children.

	* Allow RFC5424 structured data blocks to have no parameters (e.g.
	  "[foo]", which only has an SDID and no SDPARAM).

	* Fixed the value of the $PRI macro which expanded to an empty
	  string if the priority was 0 (= kern.emerg)

	* Fixed a race conditions in template compilation and expansion,
	  that could cause segmentation faults and other nastiness.

	* Fixed a race condition in macro based file destinations, which
	  caused crashes when multiple sources wrote into the same file,
	  when the filename expanded to the same name from the multiple
	  connections.  (e.g.  using $PROGRAM in the filename and receiving
	  messages from different hosts running the same programs).

	* Fixed a possible segmentation fault in certificate validation,
	  when the peer certificate contains an X.509 certificate purpose
	  extension.

	* Try to load modules with the .a extension on AIX.

	* Fixed a possible crash in the socket source with optional(yes).

	* Made stats counters and their registration thread safe, which
	  either caused crashes if stats_level() > 1 or miscalculated values
	  due to parallel threads accessing the same counters.

	* Fixed a possible crash for unknown or mistyped source flags.

	* Fixed an fd and memory leak for opened destination connections.

	* Fixed possible crashes in SIGHUP handling in case syslog-ng is
	  busy processing messages.

	* Fixed a failed assertion in persistent-state handling, triggered
	  when multiple file sources are busy processing messages and
	  recording their current file position.

	* Fixed SCL block expansion, when passing the empty value for a
	  parameter.

	* The final flush that happens right before syslog-ng exits honoured
	  the throttle() value. Since this is an attempt to squeeze out
	  everything we have to the destination, it's best to ignore
	  throttle in this case.

	* Fixed a possible use-after-free and other crash causing problems
	  in file macro based destinations.

	* Fixed a massive memory leak of all processed messages, which were
	  triggered by a change past v3.3.0beta1, but was found in a git
	  snapshot.

	* Fixed keep-alive(yes) behaviour for destination drivers.

	* Messages generated by the db-parser() will be marked as local
	  messages.

	* Implemented locking callbacks for OpenSSL, without which enabling
	  SSL and threading mode almost guaranteed a crash in case multiple
	  connections were running SSL.

	* Fixed an issue with the SQL destination, which can cause stalls in
	  message processing.

	Build changes:
	==============

	* Added --with-module-path configure option that specifies the
	  default search path for modules. The help for the older
          --with-module-dir option was clarified, it indicates where
          syslog-ng Makefiles install modules.

	* The configure script automatically adds -pthread to the CC command
	  line. Hopefully this is indeed supported on all platforms (worked
	  on the ones I've tried), and avoids having to play dirty tricks
	  with macros like _REENTRANT and _THREAD_SAFE.

	* Link unit test programs against -livykis in case we're using a
	  system-installed ivykis, rather than our private copy.

	* Fixed compile issues on Solaris.

	* Updated to a newer libmongo-client (v0.1.3)

	* Updated to a newer ivykis version (v0.19 with syslog-ng specific
	  patches)

	Performance improvements:
	=========================

	* Use the GSlice allocator for objects allocated in the fast path.

	* Avoid another use of sprintf in the LogWriter fastpath.

	* Use per-thread caches for time related functions and the DNS cache.

	* Use the string representation of IP addresses in the DNS cache, as
	  inet_ntop() performs much worse than the cache.


	Other changes:
	==============

	* Functional tests: properly detect the presence of sqlite to do the
	  sql() testing.

	* The minimum permissible value for the log-iw-size was changed to
	  100 from 10, as the per-connection window calculation has changed.
	  Earlier all connections shared the same window, starting with 3.3,
	  the window is distributed evenly to all connections, to avoid
	  starving (e.g. one connection starves the rest by using up the
	  window space) and to avoid thread synchronization in the message
	  processing fast path.

	* Ported per-facility, per-severity, per-program and per-host
	  counters from the PE version.

	* Other systemd unit files.

	syslog-ng is developed as a community project, and as such it relies
        on volunteers to do the work necessarily to produce syslog-ng.

        Reporting bugs, testing changes, writing code or simply providing
        feedback are all important contributions, so please if you are a
        user of syslog-ng, contribute.
