v2.0.0

20th April 2016

Log Courier 2.x is compatible with the 1.x Logstash plugins.

_Breaking Changes_

• CurveZMQ transport has been removed
• The lc-curvekey utility has been removed
• Multiline codecs can now be configured with multiple patterns. As such, the
  pattern configuration has been replaced with patterns and it is now an array
  of patterns
• Multiline codecs have a new match configuration that can be set to all or
  any, to control how multiple patterns are used. The default is any.
• Multiline patterns can be individually negated with a "!" prefix. The negate
  configuration directive has been removed. A "=" prefix is also possible to allow
  patterns that need to start with a literal "!"
• Filter codec patterns now also accept negation in the same method. The
  negate configuration directive has also been removed for filters and a new
  match configuration added that also defaults to any
• Multiple codecs can now be specified. As such, the codec configuration has
  been renamed to codecs and must now be an array.
• The persist directory configuration is now required, unless it was built in
  at build time (which it will be for RPM and DEB packages - see Build Changes).
• All admin prefixed configurations have been moved from the general section
  into their own admin section, and the prefix removed
• The reconnect transport configuration has been removed, and replaced with
  reconnect backoff and reconnect backoff max

_Changes_

• A new global fields configuration is available in the general section
  where fields that are to be added to all events from all paths can be specified.
  This complements the current fields configuration that is per-path.
• A new method configuration directive has been added to the network
  section, which allows random, failover or loadbalance network modes.
  Information on these new values can be found in the configuration documentation.
  The default is random for backwards compatibility.
• The dead time stream configuration directive now defaults to 1 hour
• New backoff configurations, failure backoff and failure backoff max, have
  been added, to allow backoff from problematic remote endpoints where, for
  example, connection always succeeds but transmission attempts always timeout.
• Configuration files can now be in YAML format by giving the file a .yaml
  extension, and this will be the preferred format. JSON format will continue to
  be used for .conf and .json configuration files
• The config parameter can now be omitted from log-courier if a default
  configuration file was specified during build (see Build Changes)
• lc-admin can now be given a configuration file to load the
  admin.listen address from using the config parameter. In the absense of
  both connect and config parameters it will load the default configuration file if
  one was specified during build (see Build Changes)
• Log Courier remote administration via lc-admin is now a REST interface,
  allowing third-party integrations and monitoring
• Harvester snapshot information reported by lc-admin now contains additional
  information such as the last known file size and percentage completion (#239)
• Harvester snapshot information is now updated even when the remote server is
  down
• Publisher snapshot information reported by lc-admin now contains a list of
  enabled endpoints and their statuses (#199)
• If the harvester detects a log file has had data written without a new line
  ending, it will report a warning to the log so it can be investigated

_Fixes_

• Do not open dead files on startup (which causes excessive memory usage if
  there are many of them) if their size has not changed since they were last
  opened (#242)
• When a long line was split, the "splitline" tag was not being appended if the
  fields configuration already contained tags

_RPM Packaging_

• Fix broken systemd configuration (#237)
• Fix non-fatal %postun script failure, and fix starting of Log Courier during
  package upgrade even if it was not originally started (#228)

_DEB Packaging_

• Fix broken systemd configuration (#237)

_Build Changes_

• Some configuration parameters, such as default configuration file and default
  persist directory can now be specified at build time by setting environment
  variables for them. For example: LC_DEFAULT_CONFIGURATION_FILE and
  LC_DEFAULT_GENERAL_PERSIST_DIR. These will be used in the RPM and DEB packages
  to set platform specific defaults
• Simplified the entire build process to use only Go tooling to make
  cross-platform building significantly easier, especially on Windows
• Discarded Ruby test framework in favour of developing a Go test framework over
  time
