CHANGES

3.1 (unreleased)

  • Nothing changed yet.

3.0 (2020-10-06)

Breaking changes

  • Drop support for Python 2.7.
  • Drop no longer used exception .interfaces.CounterBelowZero.

Features

  • Retry errors which happen during a transaction.commit and are configured for reraise.
  • Add support for Python 3.9.

2.1 (2020-09-18)

  • Let the Server exit in case of an socket.error. We lost the re-connection feature in 2.0 already.

2.1a1 (2020-04-17)

  • Add support for Python 3.7 and 3.8.

2.0 (2020-04-15)

  • Add support for zope.interface >= 5. (#13)
  • Change CI pipeline from Travis to GitHub Actions.

2.0a1 (2020-03-20)

Breaking changes

  • Use kombu/py-amqp instead of pika for basic abstraction over amqp methods.
  • Remove multithreading – servers and workers run in the current process.
  • Remove gocept.amqprun.main.main_server as main loop.
  • Remove configure.zcml and meta.zcml.
  • Remove writing messages in files and the amqp:writefile directive.
  • Remove writefiles extra in setup.py.
  • Remove amqp:readfile zcml directive and add send_files entrypoint for readfiles process. It takes three parameters: a configuration file path, a watch directory path and a route to send the file to. (see bin/test_send_files, details are in the README.rst).
  • Remove .channel.Channel and use amqp.channel.Channel instead.
  • Remove .interfaces.IChannelManager.
  • Remove .interfaces.ProcessStarted.
  • Remove .interfaces.ProcessStopping.
  • Remove .connection.Connection and use kombu.Connection instead.
  • Rename conf key heartbeat_interval to heartbeat in zconfig configuration.
  • Remove amount from worker zconfig.
  • Enforce content_encoding header for Message bodies that are unicode.
  • Rename .message.Message.header.headers to .message.Message.header.application_headers.
  • Rename .testing.ZCML_LAYER to .testing.ZCA_LAYER.
  • Remove .testing.LoopTestCase, use unittest.TestCase instead.
  • Remove .testing.MainTestCase.wait_for_response, use wait_for_message instead.
  • Remove .testing.SettingsLayer as it is not used here.
  • Move .connection.Parameters to .server, it now returns a dict.

Features

  • Add bin/test_sender and bin/test_server scripts to smoke test sending and receiving behaviour. See README.rst.
  • Add representation for .handler.Handler class.

1.8 (2019-09-11)

  • Update to current bootstrap.py
  • Improve forward compatibility with Python 3.
  • Fix deprecation warning.
  • Prevent using pytest >= 5 to keep Python 2 compatibility.
  • Migrate repository to github.

1.7.1 (2016-08-22)

  • Fix bug, when a string is passed as a port number to gocept.amqprun.connection.Parameters.

1.7 (2016-05-31)

  • Fix possible unresponsiveness of message handlers which occurred after an exception in the worker. The exception caused a counter under-run which prevents switching channels. The counter is no longer bound to the transaction but to the message handling.
  • Add a save guard which kills the whole process if the reference counter on the channel falls below zero.
  • Acquire the channel before putting a task to the worker queue to prevent a possible race condition.
  • Release the commit lock if tpc_abort() fails. So the next tpc_begin() does not wait forever while trying to acquire the lock and thus blocking the whole process.

1.6 (2016-04-04)

  • Allow arbitrary keywords in .testing.QueueTestCase.send_message() to be passed to generated message.

1.5 (2016-02-01)

  • Add a testing extra which can be used to reuse the test infrastructure of this package to develop tests on top of it.

1.4 (2015-11-20)

1.3 (2015-09-11)

  • Update the test infrastructure to be able to run with newer RabbitMQ versions than 3.1.5.

1.2 (2015-09-11)

  • Add py.test as test runner.
  • Add settings attribute to IHandler to ease accessing ISettings.

1.1 (2015-09-01)

  • .connection.Parameters no longer accepts arbitrary keyword parameters.

1.0 (2015-04-10)

  • Notify IConfigFinished event after gocept.amqprun is fully configured but before the workers are started. This event can be used to open database connections for instance.
  • Bump version to 1.0 as this package is used in production for years.

0.17.0 (2015-04-09)

0.16.0 (2015-03-25)

  • Raise RuntimeError if connection is not alive after connect. (This can happen when the credentials are wrong.)

0.15.2 (2015-02-24)

  • Fix error reporting in .testing.QueueLayer.rabbitmqctl().

0.15.1 (2015-01-21)

  • Moved code to and bug tracker to Bitbucket.

0.15.0 (2014-10-08)

  • Pretend to support savepoints so we can work together with other systems that support (and require) them.

0.14.0 (2014-09-09)

  • Introduce gocept.amqprun.handler.ErrorHandlingHandler base class.
  • Run integration tests (MainTestCase) in a separate ZCA, isolated from any registrations that might have been done by other tests.
  • Create temporary virtualhost on the rabbitmq server per test run.
  • Improved test-case method send_message to take headers as a parameter.

0.13.0 (2014-04-16)

  • Introduce IResponse for transaction-integrated exception handling.
  • Fix timing bug: when the remote side closes the socket and at the same time a channel switch is triggered, this used to break down (since the socket is closed). We now ignore the channel switch attempt and simply wait for the reconnect, which opens a new channel anyway.

0.12.2 (2014-02-20)

  • Add xfilename variable to the <amqp:writefiles pattern=""> setting.

0.12.1 (2014-02-20)

  • Add safeguard that two handlers cannot bind to the same queue.

0.12 (2014-02-13)

  • Include <amqp:writefiles> into the transaction handling, i.e. write to file only on commit. Previously, when an error occurred e.g. inside the MessageStored event, duplicate files would be written (each time the message was processed again on retry after the error).

0.11 (2014-01-21)

  • Crash the process on filesystem errors for <amqp:readfiles>. Previously only the file reading thread crashed, but the process kept running, unaware that it now was not doing its job anymore, since the thread had died.

0.10 (2013-05-28)

  • Support more than one Server in a single process.
  • Introduce setup_handlers parameter for Server so clients can disable setting up handlers.
  • Fix a bug in the <amqp:readfiles> transaction implementation that caused crash when aborting a transaction (#12437).
  • Allow test server to take longer time for startup on slow computers.

0.9.5 (2013-04-16)

  • Refactor Session / DataManager responsibilities (#9988).

0.9.4 (2012-09-07)

  • Fix IDataManager implementation: abort() may be called multiple times, regardless of transaction outcome. Only release the channel refcount once.

0.9.3 (2012-09-07)

  • Improve logging of IDataManager.

0.9.2 (2012-09-07)

  • Improve logging of IChannelManager.acquire/release.

0.9.1 (2012-09-06)

  • Fix IDataManager implementation: tpc_abort() may also be called without a prior tpc_begin() (happens for errors in savepoints, for example).
  • Fix method signature of Connection.close().

0.9 (2012-08-31)

  • Introduce optional integration with zope.security: handlers can declare a principal id with which an interaction will be created.
  • Use a separate channel for sending messages that are not a response to a received message.
  • Introduce SETTINGS_LAYER for tests relying on ISettings.

0.8 (2012-04-04)

  • Fix race condition that caused messages to be acknowledged on a different channel than they were received on (#10635).
  • Fix race condition that caused attempts at sending messages before the server was started properly (#10620).

0.7 (2012-03-22)

  • Fix race condition between getting the current channel in the DataManager and switching the current channel in the Server (#10521).
  • Make AMQP server configurable for tests (#9232).

0.6.1 (2012-02-23)

  • Fixed bug in creating references header when parent message has no references (#10478).

0.6 (2012-02-22)

Features

  • Changed FileStoreReader from its own process to a thread that uses gocep.amqprun for sending (previously it used amqplib). Introduced amqp:readfiles ZCML directive. (#10177)
  • Changed filestore extra to readfiles extra.
  • Transmit filename as X-Filename header from amqp:readfiles.
  • Introduced ISender utility.

Bugs

  • Fixed bug with acknowledging messages that was introduced in 0.5 (#10030).

Internal

  • Changed API for MainTestCase from create_reader to start_server.

0.5.1 (2012-01-09)

  • Bugfix to support unicode arguments for queue declaration as pika only supports bytestrings here.
  • Bugfix to make arguments parameter of amqp:writefiles work (#10115).

0.5 (2011-12-08)

General

  • Added writefiles extra to make ZCML directive amqp:writefiles optional.
  • Added filestore extra to make gocept.amqprun.filestore optional.
  • Moved declaration of amqp:writefiles from configure.zcml to meta.zcml.

Features

  • Renamed gocept.amqprun.server.MessageReader into gocept.amqprun.server.Server and added a send method so it can initiate sending of messages.
  • Add support for arguments for queue_declare e.g to support x-ha-policy headers for RabbitMQ mirrored queue deployments (#10036).

Internal

  • Internal API change in server.AMQPDataManager.__init__: the message parameter is now optional, so it was moved to the end of the list of arguments.
  • Use plone.testing for layer infrastructure.

0.4.2 (2011-08-23)

  • Add helper methods for dealing with header files to FileWriter (for #9443).

0.4.1 (2011-08-22)

  • Log Message-ID.

0.4 (2011-07-25)

  • The message id of outgoing messages is set.
  • The correlation id of outgoing messages is set to the incoming message's message id (if set).
  • A custom header references is set to the incoming message's reference header + the incomming message's message id (like References in RFC5322).
  • Fixed broken tests.
  • Allow upper case in settings keys.
  • Extend AMQP server configuration for FileStoreReader to include credentials and virtual host.
  • Allow specifying multiple routing keys (#9326).
  • Allow specifying a filename/path pattern (#9327).
  • The FileWriter stores the headers in addition to the body (#9328).
  • FileWriter sends IMessageStored event (#9335).

0.3 (2011-02-05)

  • Renamed decorator from handle to declare.
  • Added helper method wait_for_response to MainTestCase.
  • Added an IProcessStarting event which is sent during startup.
  • Added the <amqp:writefiles/> directive that sets up a handler that writes incoming messages into files.
  • Added handling of <logger> directives

0.2 (2010-09-14)

  • Added a decorator gocept.amqprun.handler.handle(queue_name, routing_key).

0.1 (2010-08-13)

  • first release.
