v2.0.0

  • Using ep01 instead of ep00 for EPICS connection events.
  • Adding the schema "se00", which is in an upgrade to the schema "senv" which could not handle floats/doubles.
  • Added support for f144 and al00 schemas.
  • Refactoring to separate Serialisers in classes that implement a typing.Protocol.

pre-2.0

  • Repetition of messages will now be triggered only if no new message has been received within the configurable repetition time (pv-update-period).
  • Drastic improvement to serialisation of f142 messages by updating to streaming-data-types 0.15.1
  • Fixed bug when serialising empty senv-messages.
  • Fixed bug where the wrong type was picked when casting numpy arrays in the f142 serialiser.
  • Known bad PV updates will no longer be cached for (attempted) re-transmission.
  • Some exceptions in the PVA/CA update handling code will now produce log messages.
  • Re-factored the code to allow automatic instantiation of forwarding modules
  • Added separate ep00 module for handling only connection status serialisation
  • New ep00 module is now automatically instantiated for every PV that the forwarder is configured to forward
  • System test running has been simplified and fixed
  • Set the "facility" and "process_name" fields in the Graylog messages to "ESS" and "forwarder"
  • System tests renamed to integration tests
  • Repeated messages will now have the Kafka timestamp set to the current system time. This in an effort to reduce the load on the Kafka broker.
