Version 2.0.4, 2017-10-04

  • added support for native JSON number formats supported by parsers: number, float, hex
  • added support for creating unix timestamps supported by parsers: date-rfc3164, date-rfc5424

liblognorm 2.0.2 released

Tuesday, November 15th, 2016

We have just released liblognorm 2.0.2. This new version provides some fixes for the the annotate function and adds a test for it. A few different issues have also been fixed. See the Changelog for details.

Changelog:
Version 2.0.2, 2016-11-15

  • bugfix: no error was emitted on invalid “annotate” line
  • “annnotate”: permit inline comments
  • fix a problem with cross-compilation
    see also: https://github.com/rsyslog/liblognorm/pull/221
    Thanks to Luca Boccassi for the patch
  • bugfix: abort in literal path compaction when useing “alternative” parser
    When using the “alternative” parser, literals nodes could be created with
    multiple reference count. This is valid. However, literal path compaction
    did not consider this case, and so “merged” these nodes, which lead to
    pdag corruption and quickly to segfault.
    closes https://github.com/rsyslog/liblognorm/issues/220
    closes https://github.com/rsyslog/liblognorm/issues/153
  • bugfix: lognormalizer could loop
    This also caused the testbench to fail on some platforms.
    due too incorrect data type
    Thanks to Michael Biebl for this fix.
  • fix misleading compiler warning
    Thanks to Michael Biebl for this fix.
  • testbench: add test for “annotate” functionality

liblognorm 2.0.1 released

Monday, August 1st, 2016

We have just released liblognorm 2.0.1. This new version provides some fixes for the public headers als well as issues in pkgconfig file. Also it requires libfastjson (>=0.99.3) instead of json-c. See the Changelog for details.

Changelog:
Version 2.0.1, 2016-08-01

  • fix public headers, which invalidly contained a strndup() definition
    Thanks to Michael Biebel for this fix.
  • fix some issues in pkgconfig file
    Thanks to Michael Biebel for this fix.
  • enhance build system to natively support systems with older autoconf versions and/or missing autoconf-archive. In this case we gracefully degrade functionality, but the build still is possible. Among others, this enables builds on CentOS 5.

liblognorm 1.1.3 released

Monday, March 7th, 2016

We have just released liblognorm 1.1.3. This release contains support for libfastjson and now works on Solaris. See the Changelog for details.

Changelog:
Version 1.1.3, 2016-03-07

  • add support for libfastjson
  • make work on Solaris
  • check for runaway rules.
    A runaway rule is one that has unmatched percent signs and thus
    is not terminated properly at its end. This also means we no longer
    accept “rule=” at the first column of a continuation line, which is
    no problem (see doc for more information).
  • fix: process last line if it misses the terminating LF
    This problem occurs with the very last line of a rulebase (at EOF).
    If it is not properly terminated (LF missing), it is silently ignored.
    Previous versions did obviously process lines in this case. While
    technically this is invalid input, we can’t outrule that such rulebases
    exist. For example, they do in the rsyslog testbench, which made
    us aware of the problem (see https://github.com/rsyslog/rsyslog/issues/489 )
    I think the proper way of addressing this is to process such lines without
    termination, as many other tools do as well.

liblognorm 1.1.2 released

Monday, July 20th, 2015

We have just released liblognorm 1.1.2. This release contains new parser syntaxes and some fixes.

Changes:
Version 1.1.2, 2015-07-20

  • permit newline inside parser definition
  • new parser “cisco-interface-spec”
  • new parser “json” to process json parts of the message
  • new parser “mac48” to process mac layer addresses
  • new parser “name-value-list” (currently inofficial, experimental)
  • some parsers did incorrectly report success when an error occurred
    this was caused by inconsistencies between various macros. We have
    changed the parser-generation macros to match the semantics of the
    broader CHKN/CHKR macros and also restructured/simplified the
    parser generation macros.
    closes https://github.com/rsyslog/liblognorm/issues/41
  • call “rest” parser only if nothing else matches.
    Versions prior to 1.1.2 did execute “rest” during regular parser
    processing, and thus parser matches have been more or less random.
    With 1.1.2 this is now always the last parser called. This may cause
    problems with existing rulesets, HOWEVER, adding any other rule or
    changing the load order would also have caused problems, so there
    really is no compatibility to preserve.
    see also:
    http://blog.gerhards.net/2015/04/liblognorms-rest-parser-now-more-useful.html
  • new API to support error callbacks
    This permits callers to forward messages in regard to e.g. wrong rule
    bases to their users, which is very useful and actually missing in the
    previous code base. So far, we only have few error messages.
    However, we will review the code and add more. The important part is
    that callers can begin to use the new API and thus will benefit when
    we add more error messages.
  • testbench is now enabled by default
  • bugfix: misadressing on some constant values
    see also https://github.com/rsyslog/liblognorm/pull/67
    Thanks to github user ontholerian for the patch
  • bugfix: add missing function prototypes
    This could potentially lead to problems on some platforms,
    especially those with 64 bit pointers.

    Thanks to Tomas Heinreich for reporting the problem.
  • added new parser syntaxes
    Thanks to Janmejay Singh for implementing most of them.
