4.7.0

  • Allow attaching multiple tags on failure. The tag_on_failure option now also supports an array of strings #100. Fixes #92

4.6.0

  • Added allow_empty_values option #72

4.5.0

  • Feat: check that target is set in ECS mode #96

4.4.1

  • Fixed issue where a field_split_pattern containing a literal backslash failed to match correctly #87

4.4.0

  • Changed timeout handling using the Timeout class #84

4.3.3

  • Fixed asciidoc formatting in docs

4.3.2

  • Resolved potential race condition in pipeline shutdown where the timeout enforcer could be shut down while work was still in-flight, potentially leading to stuck pipelines.
  • Resolved potential race condition in pipeline shutdown where work could be submitted to the timeout enforcer after it had been shutdown, potentially leading to stuck pipelines.

4.3.1

  • Fixed asciidoc formatting in documentation #81

4.3.0

  • Added a timeout enforcer which prevents inputs that are pathological against the generated parser from blocking the pipeline. By default, timeout is a generous 30s, but can be configured or disabled entirely with the new timeout_millis and tag_on_timeout directives (#79)
  • Made error-handling configurable with tag_on_failure directive.

4.2.1

  • Fixes performance regression introduced in 4.1.0 (#70)

4.2.0

  • Added whitespace => strict mode, which allows the parser to behave more predictably when input is known to avoid unnecessary whitespace.
  • Added error handling, which tags the event with _kv_filter_error if an exception is raised while handling an event instead of allowing the plugin to crash.

4.1.2

  • bugfix: improves trim_key and trim_value to trim any sequence of matching characters from the beginning and ends of the corresponding keys and values; a previous implementation limitited trim to a single character from each end, which was surprising.
  • bugfix: fixes issue where we can fail to correctly break up a sequence that includes a partially-quoted value followed by another fully-quoted value by slightly reducing greediness of quoted-value captures.

4.1.1

  • bugfix: correctly handle empty values between value separator and field separator (#58)

4.1.0

  • feature: add option to split fields and values using a regex pattern (#55)

4.0.3

  • Update gemspec summary

4.0.2

  • Fix some documentation issues

4.0.0

  • breaking: trim and trimkey options are renamed to trim_value and trim_key
  • bugfix: trim_value and trim_key options now remove only leading and trailing characters (#10)
  • feature: new options remove_char_value and remove_char_key to remove all characters from keys/values whatever their position

3.1.1

  • internal,deps: Relax constraint on logstash-core-plugin-api to >= 1.60 <= 2.99

3.1.0

  • Adds :transform_value and :transform_key options to lowercase/upcase or capitalize all keys/values

3.0.1

  • internal: Republish all the gems under jruby.

3.0.0

  • internal,deps: Update the plugin to the version 2.0 of the plugin api, this change is required for Logstash 5.0 compatibility. See elastic/logstash#5141

2.0.7

  • feature: With include_brackets enabled, angle brackets (< and >) are treated the same as square brackets and parentheses, making it easy to parse strings like "a=<b> c=<d>".
  • feature: An empty value_split option value now gives a useful error message.

2.0.6

  • internal,deps: Depend on logstash-core-plugin-api instead of logstash-core, removing the need to mass update plugins on major releases of logstash

2.0.5

  • internal,deps: New dependency requirements for logstash-core for the 5.0 release

2.0.4

  • bugfix: Fields without values could claim the next field + value under certain circumstances. Reported in #22

2.0.3

  • bugfix: fixed short circuit expressions, some optimizations, added specs, PR #20
  • bugfix: fixed event field assignment, PR #21

2.0.0

  • internal: Plugins were updated to follow the new shutdown semantic, this mainly allows Logstash to instruct input plugins to terminate gracefully, instead of using Thread.raise on the plugins' threads. Ref: elastic/logstash#3895
  • internal,deps: Dependency on logstash-core update to 2.0

1.1.0

  • feature: support spaces between key and value_split, support brackets and recursive option.
