Version 2.0.5, 2018-04-26

- bugfix: es_str2cstr leak in string-to v1 parser

  Thanks to Harshvardhan Shrivastava for the patch.

- make "make check" "succeed" on solaris 10

  actually, we just ignore the CI failures so that OpenCSW can build

  new packages. The problems actually exist on that platform, but

  testing has shown they always existed. We currently run out of time

  to really fixing this, plus we never had any bug report on Solaris

  (I assme nobody uses it on Solaris 10). However, that issues is a

  blocker to make new rsyslog versions available on OpenCSW for

  Solaris 10, so we go the dirty way of pretenting there is no

  problem. Note: the issues was orignally not seen, as the failing

  tests have been added later on. So the problem was always there,

  just not visible.

- some mostly cosmetic fixes detected by Coverity Scan

  e. g. memory leak if and only if system was completely out of memory

----------------------------------------------------------------------

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

- fixed build problems on Solaris

  ... but there still seem to be some code issues, manifested in

  testbench failures. So use with care!

----------------------------------------------------------------------

Version 2.0.3, 2017-03-22

- add ability to load rulebase from a string

  introduces new API:

  int ln_loadSamplesFromString(ln_ctx ctx, const char *string);

  closes https://github.com/rsyslog/liblognorm/issues/239

- bugfix: string parser did not correctly parse word at end of line

- bugfix: literal parser does not always store value if name is specified

  if

  rule=:%{"type":"literal", "text":"a", "name":"var"}%

  is used and matching message is provided, variable var ist not persisted.

----------------------------------------------------------------------

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

- testbench: add test for "annotate" functionality

- 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/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

----------------------------------------------------------------------

Version 2.0.1, 2016-08-01

- fix public headers, which invalidly contained a strndup() definition

  Thanks to Michael Biebl for this fix.

- fix some issues in pkgconfig file

  Thanks to Michael Biebl 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.

----------------------------------------------------------------------

Version 2.0.0, 2016-07-21

- completely rewritten, much feature-enhanced version

- requires libfastjson instead of json-c

- big improvements to testbench runs, especially on travis

  among others, the static analyzer is now run and testbench throws

  an error if the static analyzer (via clang) is not clean

- lognormalizer tool can now handle lines larger 10k characters

  Thanks to Janmejay Singh for the patch

----------------------------------------------------------------------

Version 1.1.3, 2015-??-?? [no official release]

- 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.

----------------------------------------------------------------------

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.

----------------------------------------------------------------------

Version 1.1.1, 2015-03-09

- fixed library version numbering

  Thanks to Tomas Heinreich for reporting the problem.

- added new parser syntaxes

  Thanks to Janmejay Singh for implementing most of them.

- bugfix: function ln_parseFieldDescr() returns state value

  due to unitialized variable. This can also lead to invalid

  returning no sample node where one would have to be created.

----------------------------------------------------------------------

Version 1.1.0, 2015-01-08

- added regular expression support

  use this feature with great care, as it thrashes performance

  Thanks to Janmejay Singh for implementing this feature.

- fix build problem when --enable-debug was set

  closes: https://github.com/rsyslog/liblognorm/issues/5

----------------------------------------------------------------------

Version 1.0.1, 2014-04-11

- improved doc (via RST/Sphinx)

- bugfix: unparsed fields were copied incorrectly from non-terminated

  string. Thanks to Josh Blum for the fix.

- bugfix: mandatory tag did not work in lognormalizer

----------------------------------------------------------------------

Version 1.0.0, 2013-11-28

- WARNING: this version has incompatible interface and older programs 

  will not compile with it.

  For details see http://www.liblognorm.com/news/on-liblognorm-1-0-0/

- libestr is not used any more in interface functions. Traditional

  C strings are used instead. Internally, libestr is still used, but

  scheduled for removal.

- libee is not used any more. JSON-C is used for object handling

  instead. Parsers and formatters are now part of liblognorm.

- added new field type "rest", which simply sinks all up to end of

  the string.

- added support for glueing two fields together, without literal 

  between them. It allows for constructs like:

  %volume:number%%unit:word%

  which matches string "1000Kbps"

- Fix incorrect merging of trees with empty literal at end

  Thanks to Pavel Levshin for the patch

- this version has survived many bugfixes
