[syslog-ng] syslog-ng 3.7.2

[Budai, László]

3.7.2

This is the first maintenance release for the 3.7.x series.

Changes compared to 3.7.1:
Improvements

   -

   Added mbox() source.
   This source can be used to fetch emails from local mbox files:
   source { mbox("/var/spool/mail/root"); };
   This will fetch root emails and parse them into a multiline $MSG.
   Original implementation by Fabien Wernli, I only converted it into
   an SCL.
   -

   It is possible to append dynamically options into SCL blocks from now.
   -

   concurrent_request option added to ElasticSearch with default value 1.
   -

   In elasticsearch destinaton, message_template() argument renamed to
   template().
   -

   SCL added to every Java module (ElasticSearch, Kafka, HDFS).
   -

   Linux Audit Parser added for parsing key-value pairs produced by
   the Linux Audit subsystem.
   -

   HTTP destination is now able to receive HTTP method as an option.
   All the supported methods are available
   (POST, PUT, HEAD, OPTIONS, DELETE, TRACE, GET).

Fixes

   -

   In some circumstances syslog-ng mod-journal re-read every already
   processed messages.
   -

   When syslog-ng got a reload and the reload process done within 1 second
   then
   mafter the reload, syslog-ng stop generating mark-messages.
   -

   When initialization of a network destination in syslog-ng failed (eg.
   due to
   DNS resolution failure) we didn't create a queue which caused message
   loss.
   -

   syslog-ng segfaulted on TLS errors when wrong certs was provided
   (eg.: CA cert with the cert-file directive instead of the server cert).
   -

   Fixed a continuous spinning case in the file driver, when the
   destination file is a device (e.g. /dev/stdout).
   -

   A memory leak in around template functions in grammar fixed.
   -

   Fixed Python3 support.
   -

   Fixed Python GIL issue in python destination.
   -

   From now, instead of skipping doc/ alltogether when ENABLE_MANPAGES is
   not set, only skip the actual man pages, but handle the rest properly.
   -

   Allow overriding the python setup.py options.

   When installing the python modules, allow overriding the options. This
   is useful for distributions that want to pass extra options. For
   example, on Debian, we want --install-layout="deb" instead of the
   --prefix and --root options.

   With this change, the previous behaviour remains the default, but one
   can supply PYSETUP_OPTIONS on the make command-line to override it.
   -

   The systemd service file read /etc/default/syslog-ng and
   /etc/sysconfig/syslog-ng,
   but didn't do anything with their contents. $SYSLOGNG_OPTS added to
   ExecStart, so
   that the EnvironmentFiles have an effect (at least on Debian).
   -

   Java support checking fixed (not only jdk is required but also gradle).
   -

   Memory leak around ping() in Redis fixed.
   -

   A crash in pdbtool fixed around r_parser_email().
   -

   Removed cygwin fdlimit statement.
   Make the default for RLIMIT_NOFILE equal to the current system limits.
   --fd-limit can still override this, but the default will be configured
   based on existing system limits.
   -

   Fixed BSD year inference.
   Fixed logic and made clearer the inference of year from bsd-style
   rfc3164 syslog-messages, which do not include a year.
   -

   Handle correctly the epoch 0 timestamp.
   (Previously, syslog-ng cached the zero timestamp and treated 1970 as it
   was
   1900.)
