Features

  • Support added for if/elif/else blocks to the configuration file syntax. (#1856)
  • Dramatically improved debug messages during filter/parser evaluation. (#1898)
  • Similarly improved the error messages shown on syntax errors, they now show a full backtrace of inclusions, among other things. (#1932)
  • The hook-commands module was added, allowing one to run custom commands on source or destination setup and teardown. (#1951)
  • Implemented a way to skip processing included config file snippets in case a dependency is missing: The @requires json pragma. (#827, #1956)
  • Basic client-side failover support was implemented. (#1905)
  • Errors from python destinations are now reported together with any exception text (if any). (#1931)
  • add-contextual-data gained a new ignore-case() option. (#1911)

Bugfixes

  • Fix a crash that happened on disk queue restart. (#1886)
  • Fixed another crash when a corrupted disk queue file was being moved away. (#1924)
  • Fixed a crash that could happen during nvtable deserialization. (#1967)
  • Fixed a crash that occurred when NVTables were stored on low memory addresses. (#1970)
  • Fixed an issue with TLS session resumption, the session id context value is now properly set. (#1936, #2000)
  • We now link directly to the evtlog shipped with syslog-ng, and are not using the system library, not even when present. (#1915)
  • TLS destinations now work again without key-file or cert-file specified. (#1916, #1917)
  • SDATA block names are now sanitized, in order to not break the spec when we get our SDATA from sources that are more lax (such as JSON). (#1948)
  • Some internal messages contained key-value pairs where the key had spaces in it, this has been addressed, they do not contain spaces anymore.
  • The STOMP destination will now correctly use template options when formatting its body part. (#1957)

  • The Docker environment (dbld/) has seen significant changes, among them an upgrade to Ubuntu Xenial. (#1876)
  • dbld/rules gained two new targets: login and build, that do what their names suggest. (#1927)
  • The LogPipe object gained a pre_init() and a post_deinit() method, used by the hook-commands module.
