Version 4.3.0 [DEVEL] (rgerhards), 2009-04-17

• new feature: new output plugin omprog, which permits to start program and feed it (via its stdin) with syslog messages. If the program terminates, it is restarted.
• improved internal handling of RainerScript functions, building the necessary plumbing to support more functions with decent runtime performance. This is also necessary towards the long-term goal of loadable library modules.
• added new RainerScript function “tolower”
• improved testbench
  • added tests for tcp-based reception
  • added tcp-load test (1000 connections, 20,000 messages)
• added $MaxOpenFiles configuration directive
• bugfix: solved potential memory leak in msg processing, could manifest itself in imtcp
• bugfix: ompgsql did not detect problems in sql command execution this could cause loss of messages. The handling was correct if the connection broke, but not if there was a problem with statement execution. The most probable case for such a case would be invalid sql inside the template, and this is now much easier to diagnose.

Version 4.1.6 [DEVEL] (rgerhards), 2009-04-07

• added new “csv” property replacer options to enable simple creation of CSV-formatted outputs (format from RFC4180 is used)
• implemented function support in RainerScript. That means the engine parses and compile functions, as well as executes a few build-in ones. Dynamic loading and registration of functions is not yet supported – but we now have a good foundation to do that later on.
• implemented the strlen() RainerScript function
• added a template output module
• added -T rsyslogd command line option, enables to specify a directory where to chroot() into on startup. This is NOT a security feature but introduced to support testing. Thus, -T does not make sure chroot() is used in a secure way. (may be removed later)
• added omstdout module for testing purposes. Spits out all messages to stdout – no config option, no other features
• added a parser testing suite (still needs to be extended, but a good start)
• modified $ModLoad statement so that for modules whom’s name starts with
  a dot, no path is prepended (this enables relative-pathes and should not break any valid current config)

• fixed a bug that caused action retries not to work correctly situation was only cleared by a restart
• bugfix: closed dynafile was potentially never written until another dynafile name was generated – potential loss of messages
• improved omfile so that it properly suspends itself if there is an i/o or file name generation error. This enables it to be used with the full high availability features of rsyslog’s engine
• bugfix: fixed some segaults on Solaris, where vsprintf() does not check for NULL pointers
• improved performance of regexp-based filters. Thanks to Arnaud Cornet for providing the idea and initial patch.
• added a new way how output plugins may be passed parameters. This is more effcient for some outputs. They new can receive fields not only as a single string but rather in an array where each string is seperated.
• added (some) developer documentation for output plugin interface
• bugfix: potential abort with DA queue after high watermark is reached There exists a race condition that can lead to a segfault. Thanks go to vbernetr, who performed the analysis and provided patch, which I only tweaked a very little bit.
• bugfix: imtcp did incorrectly parse hostname/tag Thanks to Luis Fernando Muñoz Mejías for the patch.
