Logstash Filter Verifier Change Log

All timestamps are in the Europe/Stockholm timezone.

1.6.2 (2020-11-21)

  • Fixed race condition bug that sometimes caused the summary to not get shown at the end of the execution.
  • Upgraded the Go compiler used for release binaries and CI to 1.15.2.

1.6.1 (2020-06-30)

  • Slightly changed output format with a summary included at the end.
  • The codec test case file option is inserted in the configuration file verbatim rather than as a string literal, allowing the user to provide additional codec options.

1.6.0 (2020-01-02)

  • Upgraded the Go compiler to 1.13 and transitioned to using Go modules for dependency management.
  • Dropped Debian packaging support.
  • Allow test case file to be in YAML format instead of JSON.
  • Support Logstash's field reference syntax ([field][subfield]) in the ignore test case file option to ignore only certain subfields.

1.5.1 (2019-07-11)

  • The temporary directory to which the configuration files are copied is now created with mode 0700. This addresses a security vulnerability when configuration files contain secrets.
  • Test flakiness when used with Logstash 7 is addressed by limiting the pipeline batch size to a single message.

1.5.0 (2018-09-09)

  • Allow keeping multiple environment variables with --keep-env.
  • Input and outputs sections are automatically removed from the Logstash configurations under test. That way you don't have to segregate different kinds of plugin into different configuration files and take care to never pass any files containing inputs and outputs to LFV.
  • The command line argument for Logstash configuration files to test can now include directories and not just files.
  • Testcase files with the "fields" key set to null no longer causes LFV to panic.
  • Fix "make install" on Mac OS X by omitting the -s/--strip option to install(1).

1.4.1 (2018-01-01)

  • Fix for a crash when using --sockets with a testcase file without a "fields" option.

1.4.0 (2017-12-17)

  • Full support for Logstash 5 and later. By default the version used with LFV is auto-detected (in order to adapt the LFV behavior) but this can be overridden with --logstash-version.
  • --logstash-path no longer sets the singular Logstash path but rather adds an extra entry to the list of locations that are checked for a Logstash installation.
  • When using --sockets a magic [@metadata][__lfv_testcase] field was added, but it would clobber any existing @metadata fields. This field is now appended to any existing @metadata fields.

1.3.0 (2017-05-21)

  • The --sockets option is incompatible with a couple of input codecs that happen to work if you don't use that option. Warn the use about this.
  • Addition of a --logstash-arg option that allows the user to pass additional arguments to all started Logstash processes.
  • The PATH environment variable is by default passed on to started Logstash processes. This fixes a bug where Logstash under some circumstances isn't able to find the JVM.

1.2.1 (2017-04-05)

  • Addition of --sockets-timeout option to control how long to wait for Logstash to start up and become ready to process events when using the --sockets option.
  • Status and progress messages are now written to stdout instead of stderr.
  • Addition of a "description" field for test cases that e.g. can be used as a short piece of documentation.

1.2.0 (2017-02-21)

  • Logstash 5.2 compatibility. Issues still exist with Logstash 5.0 and possibly 5.1.
  • Addition of --sockets option that causes the program to use Unix domain sockets to pass inputs to Logstash, enabling a single Logstash process to be used for multiple test case files which has the potential to dramatically shorten the execution time.
  • Go 1.8 is now required for compiling.
  • Support for a new test case file format where pairs of input and expected output lines are store together. For now both formats work.
  • Addition of --logstash-output option that causes the Logstash output to be emitted.
  • JSON parse errors for test case files are reported with line and column details to make it easier to find the problem.
  • The makefile now supports a GOPATH variable with multiple paths.
  • When adding fields to input events with the fields option, nested fields may now be objects.
  • Large floating point numbers are now formatted in a way that's acceptable to Logstash.
  • Minor improvements in the messages given when running the program.

1.1.1 (2016-07-31)

  • Multiple filter configuration files now work. Previously only one of the files would be picked up by Logstash, possibly resulting in incorrect test results.
  • When invoking with --help to get command-line help, the exit code is now zero.

1.1.0 (2016-02-25)

  • Adds the --keep-env option to keep select environment variables when invoking Logstash. Useful to propagate JAVA_HOME and any other variables needed by Logstash.
  • If the Logstash child process terminates with a non-zero exit code, show the stdout/stderr output from the command rather than solely relying on the log output. If Logstash fails very early, e.g. before the JVM starts up, there won't be a logfile.

1.0.1 (2016-02-11)

  • Fixes Logstash 2.2.0 incompatibility problem.
  • If the Logstash child process terminates with a non-zero exit code, the contents of Logstash's log file is now included in the error message.

1.0.0 (2016-01-10)

  • Initial release.
