DESCRIPTION:
A new stable version of syslog-ng Open Source Edition (3.3.0beta1) has been
released. For latest fixes in the 3.3.x branch you are recommended to
upgrade to this version.
CHANGES:
3.3.0beta1

Highlights:
===========
This release marks the feature freeze for the upcoming 3.3 version
of syslog-ng, development continues on the newly opened 3.4 branch,
while this one only receives bugfixes in the future.
db-parser():
============
* db-parser() has a new option called inject-mode() that can be used
to specify where synthetic messages generated by syslog-ng itself
should be injected. In 3.2 these appeared in the internal()
source, in 3.3 they'll be generated from within db-parser().
* "pdbtool patternize": added --no-parse option
sql():
======
* Make the number of retries runtime configurable in case an INSERT
is rejected by the database using the new retry-sql-inserts()
option.
* Added support for using the "default" value for columns, by
specifying "default" as the column value. This can be used for
auto-incrementing fields.
* Explicit commits were adapted to use the proper BEGIN TRANSACTION
command on MS SQL and Oracle.
* Oracle doesn't like overly long index names, and since this limit
was easily reached by syslog-ng, use md5 to compress the index
name.
* Removed the defaults for columns(), values() and indexes() as it's
almost impossible to come up with a set of defaults that works on
all databases.
* DBI initialization errors are reported earlier, during startup, to
make their detection easier.
file():
=======
* The owner(), group(), perm(), dir_owner(), dir_group() and
dir_perm() can be specified without an argument which tells
syslog-ng to avoid changing file permissions even if the globals
are set.
mongodb():
==========
* The name of the collection was changed to be a simple string,
instead of a template, to make implementing bulk inserts much
easier.
* Added support for the value-pairs() option, that makes it trivial
to add fields to records dynamically.
$(format-json):
===============
* A new module named tfjson was created which implements a
$(format-json) template function, capable of exporting the
syslog-ng message model as a properly marked up JSON object.
* The plugin supports both json-c and json-glib as backend
implementations.
Performance changes:
====================
* The LogQueue component was restructured for better scalability.
This component is responsible to connect source and destination
drivers as they work in separate threads, and as such it plays an
important role in influencing the overall performance of syslog-ng.
Loggen:
=======
* Added support for reading files in multi-threaded mode (each
thread sending a copy of that file, instead of mixing lines).
* Added support for IPv6.
Other changes:
==============
* The list of plugins loaded by default became build-time
configurable using the --default-modules configure switch. The
same command line option can be used to override the same at
runtime.
* --version now includes information on the list of available
modules, and --module-registry displays even more information on
every loadable module.
* Introduced another plugin possibility, inner-source and inner-dest
plugin types allow the extension any kind of source or destination
driver.
* Use the newly introduced "cap-syslog" capability with kernels
post-2.6.38.
Build changes:
==============
* A new shared library was introduced named libsyslog-ng-crypto.so
that contains all crypto related code shared between plugins.
* Added pkg-config files to be used in -dev packages in order to
make it possible to build external modules.
* "make uninstall" now properly uninstalls config files and SCL.
Note that it removes everything without checking that they were
changed locally.
Bugfixes:
=========
* The program destination caused a segmentation fault during
startup, this was fixed.
* Fixed syslog() style framing over TLS or tcp, which caused the
syslog-ng server to shut connections down prematurely.
* Fixed syslog() client code, which may cause invalid framing to be
emitted on contended network connections.
* Fixed a possibly failed assert in the flow control code in
reaction to a broken source connection.
* Fixed processing flush_timeout() for destinations, in earlier
alpha versions flush_timeout() never expired.
* Some platforms return EINVAL for writev() calls with zero I/O
buffers, causing file output to fail. Make sure syslog-ng never
generates such calls.
* Fixed read behaviour for special files (like /proc/kmsg on
Linux, /dev/klog for FreeBSD), as epoll/kqueue is unable to handle
these.
* Fixed write behaviour for special files (like /dev/console) as
epoll/kqueue must be used even though syslog-ng doesn't use those
for regular files.
* Fixed a premature connection closure when the destination is
unable to accept data (e.g. EAGAIN is returned from send()). This
was easily reproduced by enabling SSL, as SSL is reporting the
same condition when the negotiation is running and the client is
expecting the response from a server.
* Fixed a 100% CPU usage case in the SSL server case.
* Fixed a possible segmentation fault during runtime (use-after-free
problem which could cause segfaults).
* Fixed a segmentation fault at exit when the tcp() destination
couldn't connect to the server.
* Don't attempt to remember the file position for files that are
read using follow-freq(0), e.g. /dev/klog, /proc/kmsg and similar
files.
* Fixed a db-parser() correllation bug, sometimes timers were not
expired as they should have. [3.2 port]
* Accept three forms of the catch-all log statement flag: catch-all,
catchall and catch_all since the documentation was wrong and it
differed from the actual implementation for ages.
* PCRE: fixed a potential resource hog triggered by PCRE 8.12 and
"global" replacements.
* loggen: make sure loggen sends out all data by calling shutdown()
on the output socket.
* loggen: handle SIGPIPE signals which caused loggen to exit
prematurely when connections broke.
* loggen: fixed a potential division by zero when reporting the
message rate for unsuccessful connections.
* Fixed a number of compilation warnings triggered by gcc 4.6
