v1.6.1

Added

• RabbitmqBroker now supports multiple connection uris to be passed in via its url parameter. (#216, @wsantos)

Changed

• Updated allowed version range for prometheus-client. (#219, @robinro)

v1.6.0

Added

• dramatiq_queue_prefetch environment variable to control the number of messages to prefetch per worker thread. (#183, #184, @xelhark)
• The RabbitMQ broker now retries the queue declaration process if an error occurs. (#179, @davidt99)
• Support for accessing nested broker instances from the CLI. (#191, @bersace)
• Support for eagerly raising actor exceptions in the joining thread with the StubBroker. (#195, #203)
• Support for accessing the current message from an actor via CurrentMessage. (#208)

Changed

• Pinned pika version >1.0,<2.0. (#202)

Fixed

• An issue where workers would fail and never recover after the connection to Redis was severed. (#207)
• pipe_ignore has been fixed to apply to the next message in line within a pipeline. (#194, @metheoryt)

v1.5.0

Added

• The RabbitMQ broker now supports native message priorities. (#157, @davidt99)
• Support for specifying the actor class to @actor. (#169, @gilbsgilbs)

Changed

• Pika 0.13 is now required.

Fixed

• Consumers are now stopped after workers finish running their tasks. (#160, @brownan)
• Worker logging on Python 3.7 is no longer delayed.

v1.4.3

Fixed

• Changed license classifier to the correct license. This is why you shouldn't publish changed before you've had coffee, folks!

v1.4.2

This release was removed from PyPI because it had a bad license classifier (GPLv3+ instead of LGPLv3+) due to a mistake on my part.

Fixed

• License classifier in PyPI package. There were no source code
  changes for this release.

v1.4.1

Added

• Support for redis-py 3.x. (#142, @maerteijn)

Fixed

• Workers wait for RMQ messages to be acked upon shutdown. (#148)
• Pipelines no longer continue when a message is failed. (#151, @davidt99)
• Log files now work under Windows. (#141, @ryansm1)

v1.4.0

This is a big one!

Added

• Barriers.

Changed

• cli.main now takes an optional argument namespace so that users
  may define their own entrypoints. (#140, @maerteijn)
• Actor "message received" and "completed in x ms" log messages are
  now logged with the DEBUG level instead of INFO level. This
  improves throughput and makes logging much less verbose.
• The TimeLimit middleware no longer uses signals to trigger time
  limit handling. Instead it uses a background thread per worker
  process.
• Dramatiq now shuts itself down if any of the workers die
  unexpectedly (for example, if one of them is killed by the OOM
  killer).
• Windows is now supported (with some caveats)! (#119, @ryansm1)

Fixed

• Allow pipe_ignore option to be set at the actor level. (#100)
• Result encoder now defaults to the global encoder. (#108, @xdmiodz)
• Dot characters are now allowed in queue names. (#111)
• Tests are now run on Windows. (#113, @ryansm1)

v1.3.0

Changed

• Upgraded prometheus_client to 0.2.x.
• Bumped pika to version 0.12. Because of this change, the interrupt method on Broker and its usages within Worker have been dropped.
• There is no longer a max message delay.

Fixed

• Brokers can now be passed an empty list of middleware. (#90)
• Potential stack overflow when restarting Consumer threads. (#89)

v1.2.0

Added

• Support for worker heartbeats to RedisBroker.
• maintenance_chance and heartbeat_timeout parameters to
  RedisBroker.
• Interrupt base class for thread-interrupting exceptions. (@rpkilby)
• ShutdownNotifications middleware. (@rpkilby)

Changed

• TimeLimitExceeded is now a subclass of Interrupt.

Fixed

• StubBroker.join and Worker.join are now more reliable.
• Module import path is now prepended to search path rather than
  appended. This fixes an issue where importing modules with the same
  name as modules from site-packages would end up importing the
  modules from site-packages. (#88)
• Prometheus middleware no longer wipes the prometheus data
  directory on startup. This fixes an issue with exporting
  application metrics along with worker metrics.
