Release Notes

2.0.1 (2020-01-02)

Bug Fixes

  • Fix handling of new connections after a publish timeout (#212)

2.0.0 (2019-12-03)

Dependency Changes

  • Drop official Python 3.4 and 3.5 support
  • Bump the pika requirement to 1.0.1+
  • New dependency: Crochet

API Changes

  • Move all APIs to use the Twisted-managed connection. There are a few minor changes here which slightly change the APIs:
    1. Publishing now raises a PublishTimeout when the timeout is reached (30 seconds by default).
    2. Previously, the Twisted consume API did not validate arguments like the synchronous version did, so it now raises a ValueError on invalid arguments instead of crashing in some undefined way.
    3. Calling publish from the Twisted reactor thread now raises an exception instead of blocking the reactor thread.
    4. Consumer exceptions are not re-raised as HaltConsumer exceptions anymore, the original exception bubbles up and has to be handled by the application.

Features

  • The fedora-messaging cli now has 2 new sub-commands: publish and record. (PR#43)
  • Log the failure traceback on connection ready failures.

Bug Fixes

  • Fix an issue where reconnection to the server would fail. (#208)
  • Don’t declare exchanges when consuming. (#171)
  • Fix Twisted legacy logging (it does not accept format parameters).
  • Handle ConnectionLost errors in the v2 Factory.

Development Changes

  • Many Twisted-related tests were added.
  • Include tests for sample schema package.
  • Update the dumps and loads functions for a new message format.

Documentation Improvements

  • Document that logging is only set up for consumers.
  • Update the six intersphinx URL to fix the docs build.
  • Add the “conf” and “DEFAULTS” variables to the API documentation.
  • Update example config: extra properties, logging.
  • Document a quick way to setup logging.
  • Document the sent-at header in messages.
  • Create a quick-start guide.
  • Clarify queues are only deleted if unused.
  • Wire-format: improve message properties documentation.
  • Note the addition client properties in the config docs.

v1.7.1 (2019-06-24)

Bug Fixes

Contributors

Many thanks to the contributors of bug reports, pull requests, and pull request reviews for this release:

  • Randy Barlow
  • Aurélien Bompard
  • Jeremy Cline
  • Adam Williamson

Documentation Improvements

  • Document some additional app properties and add a note about setting up logging in the fedora.toml and stg.fedora.toml configuration files (PR#188)
  • Document how to setup logging in the consuming snippets so any problems are logged to stdout (PR#192)
  • Document that logging is only set up for consumers (#181)
  • Document the fedora_messaging.config.conf and fedora_messaging.config.DEFAULTS variables in the API documentation (#182)

v1.7.0 (2019-05-21)

Features

  • “fedora-messaging consume” now accepts a “–callback-file” argument which will load a callback function from an arbitrary Python file. Previously, it was required that the callback be in the Python path (#159).

Bug Fixes

  • Fix a bug where publishes that failed due to certain connection errors were not retried (#175).
  • Fix a bug where AMQP protocol errors did not reset the connection used for publishing messages. This would result in publishes always failing with a ConnectionError (#178).

Documentation Improvements

  • Document the body attribute on the Message class (#164).
  • Clearly document what properties message schema classes should override (#166).
  • Re-organize the consumer documentation to make the consuming API clearer (#168).

v1.6.1 (2019-04-17)

Bug Fixes

v1.6.0 (2019-04-04)

Dependency Changes

  • Twisted is no longer an optional dependency: fedora-messaging requires Twisted 12.2 or greater.

Features

  • A new API, fedora_messaging.api.twisted_consume(), has been added to support consuming using the popular async framework Twisted. The fedora-messaging command-line interface has been switched to use this API. As a result, Twisted 12.2+ is now a dependency of fedora-messsaging. Users of this new API are not affected by Issue #130 (PR#139).

Bug Fixes

  • Only prepend the topic_prefix on outgoing messages. Previously, the topic prefix was incorrectly applied to incoming messages (#143).

Documentation

  • Add a note to the tutorial on how to instal the library and RabbitMQ in containers (PR#141).
  • Document how to access the Fedora message broker from outside the Fedora infrastructure VPN. Users of fedmsg can now migrate to fedora-messaging for consumers outside Fedora’s infrastructure. Consult the new documentation at Fedora’s Public Broker for details (PR#149).

v1.5.0 (2019-02-28)

Dependency Changes

  • Replace the dependency on pytoml with toml (#132).

Features

  • Support passive declarations for locked-down brokers (#136).

Bug Fixes

  • Fix a bug in the sample schema pachage (#135).

v1.2.0 (2019-01-21)

Features

  • The fedora_messaging.api.consume() API now accepts a “queues” keyword which specifies the queues to declare and consume from, and the “fedora-messaging” CLI makes use of this (PR#107)
  • Utilities were added in the schema_utils module to help write the Python API of your message schemas (PR#108)
  • No long require “–exchange”, “–queue-name”, and “–routing-key” to all be specified when using “fedora-messaging consume”. If one is not supplied, a default is chosen. These defaults are documented in the command’s manual page (PR#117)

Bug Fixes

  • Fix the “consumer” setting in config.toml.example to point to a real Python path (PR#104)
  • fedora-messaging consume now actually uses the –queue-name and –routing-key parameter provided to it, and –routing-key can now be specified multiple times as was documented (PR#105)
  • Fix the equality check on fedora_messaging.message.Message objects to exclude the ‘sent-at’ header (PR#109)
  • Documentation for consumers indicated any callable object was acceptable to use as a callback as long as it accepted a single positional argument (the message). However, the implementation required that the callable be a function or a class, which it then instantiated. This has been fixed and you may now use any callable object, such as a method or an instance of a class that implements __call__ (PR#110)
  • Fix an issue where the fedora-messaging CLI would only log if a configuration file was explicitly supplied (PR#113)

  • The setupRead API in the Twisted protocol has been removed and replaced with consume and cancel APIs which allow for multiple consumers with multiple callbacks (PR#72)

The initial alpha release for fedora-messaging v1.0.0. The API is not expected to change significantly between this release and the final v1.0.0 release, but it may do so if serious flaws are discovered in it.
