Commits:

Travis CI fail fast - 3f0e739

New features:

BlockingConnection.consume now returns (None, None, None) when inactivity timeout is reached (PR)

BlockingConnection now supports the add_callback_threadsafe method which allows a function to be executed correctly on the IO loop thread. The main use-case for this is as follows:

  • Application sets up a thread for BlockingConnection and calls basic_consume on it
  • When a message is received, work is done on another thread
  • When the work is done, the worker uses connection.add_callback_threadsafe to call the basic_ack method on the channel instance.

Please see examples/basic_consumer_threaded.py for an example. As always, SelectConnection and a fully async consumer/publisher is the preferred method of using Pika.

Heartbeats are now sent at an interval equal to 1/2 of the negotiated idle connection timeout. RabbitMQ's default timeout value is 60 seconds, so heartbeats will be sent at a 30 second interval. In addition, Pika's check for an idle connection will be done at an interval equal to the timeout value plus 5 seconds to allow for delays. This results in an interval of 65 seconds by default.

0.11.0 2017-07-29

GitHub milestone

0.11.0

  • Simplify Travis CI configuration for OS X.
  • Add [asyncio]{.title-ref} connection adapter for Python 3.4 and newer.
  • Connection failures that occur after the socket is opened and before the AMQP connection is ready to go are now reported by calling the connection error callback. Previously these were not consistently reported.
  • In BaseConnection.close, call _handle_ioloop_stop only if the connection is already closed to allow the asynchronous close operation to complete gracefully.
  • Pass error information from failed socket connection to user callbacks on_open_error_callback and on_close_callback with result_code=-1.
  • ValueError is raised when a completion callback is passed to an asynchronous (nowait) Channel operation. It's an application error to pass a non-None completion callback with an asynchronous request, because this callback can never be serviced in the asynchronous scenario.
  • [Channel.basic_reject]{.title-ref} fixed to allow [delivery_tag]{.title-ref} to be of type [long]{.title-ref} as well as [int]{.title-ref}. (by quantum5)
  • Implemented support for blocked connection timeouts in [pika.connection.Connection]{.title-ref}. This feature is available to all pika adapters. See [pika.connection.ConnectionParameters]{.title-ref} docstring to learn more about [blocked_connection_timeout]{.title-ref} configuration.
  • Deprecated the [heartbeat_interval]{.title-ref} arg in [pika.ConnectionParameters]{.title-ref} in favor of the [heartbeat]{.title-ref} arg for consistency with the other connection parameters classes [pika.connection.Parameters]{.title-ref} and [pika.URLParameters]{.title-ref}.
  • When the [port]{.title-ref} arg is not set explicitly in [ConnectionParameters]{.title-ref} constructor, but the [ssl]{.title-ref} arg is set explicitly, then set the port value to to the default AMQP SSL port if SSL is enabled, otherwise to the default AMQP plaintext port.
  • [URLParameters]{.title-ref} will raise ValueError if a non-empty URL scheme other than {amqp | amqps | http | https} is specified.
  • [InvalidMinimumFrameSize]{.title-ref} and [InvalidMaximumFrameSize]{.title-ref} exceptions are deprecated. pika.connection.Parameters.frame_max property setter now raises the standard [ValueError]{.title-ref} exception when the value is out of bounds.
  • Removed deprecated parameter [type]{.title-ref} in [Channel.exchange_declare]{.title-ref} and [BlockingChannel.exchange_declare]{.title-ref} in favor of the [exchange_type]{.title-ref} arg that doesn't overshadow the builtin [type]{.title-ref} keyword.
  • Channel.close() on OPENING channel transitions it to CLOSING instead of raising ChannelClosed.
  • Channel.close() on CLOSING channel raises [ChannelAlreadyClosing]{.title-ref}; used to raise [ChannelClosed]{.title-ref}.
  • Connection.channel() raises [ConnectionClosed]{.title-ref} if connection is not in OPEN state.
  • When performing graceful close on a channel and [Channel.Close]{.title-ref} from broker arrives while waiting for CloseOk, don't release the channel number until CloseOk arrives to avoid race condition that may lead to a new channel receiving the CloseOk that was destined for the closing channel.
  • The [backpressure_detection]{.title-ref} option of [ConnectionParameters]{.title-ref} and [URLParameters]{.title-ref} property is DEPRECATED in favor of [Connection.Blocked]{.title-ref} and [Connection.Unblocked]{.title-ref}. See [Connection.add_on_connection_blocked_callback]{.title-ref}.

Details

Python 3.x: this release introduces python 3.x support. Tested on Python 3.3 and 3.4.

`AsyncoreConnection`: Retired this legacy adapter to reduce maintenance burden; the recommended replacement is the [SelectConnection]{.title-ref} adapter.

`SelectConnection`: ioloop was refactored for compatibility with other ioloops.

`Channel.add_on_return_callback`: The callback is now passed the individual parameters channel, method, properties, and body instead of a tuple of those values for congruence with other similar callbacks.

`BlockingConnection`: This adapter underwent a makeover under the hood and gained significant performance improvements as well as enhanced timer resolution. It is now implemented as a client of the [SelectConnection]{.title-ref} adapter.

Below is an overview of the [BlockingConnection]{.title-ref} and [BlockingChannel]{.title-ref} API changes:

  • Recursion: the new implementation eliminates callback recursion that sometimes blew out the stack in the legacy implementation (e.g., publish -> consumer_callback -> publish -> consumer_callback, etc.). While [BlockingConnection.process_data_events]{.title-ref} and [BlockingConnection.sleep]{.title-ref} may still be called from the scope of the blocking adapter's callbacks in order to process pending I/O, additional callbacks will be suppressed whenever [BlockingConnection.process_data_events]{.title-ref} and [BlockingConnection.sleep]{.title-ref} are nested in any combination; in that case, the callback information will be bufferred and dispatched once nesting unwinds and control returns to the level-zero dispatcher.

  • `BlockingConnection.connect`: this method was removed in favor of the constructor as the only way to establish connections; this reduces maintenance burden, while improving reliability of the adapter.

  • `BlockingConnection.process_data_events`: added the optional parameter [time_limit]{.title-ref}.

  • `BlockingConnection.add_on_close_callback`: removed; legacy raised [NotImplementedError]{.title-ref}.

  • `BlockingConnection.add_on_open_callback`: removed; legacy raised [NotImplementedError]{.title-ref}.

  • `BlockingConnection.add_on_open_error_callback`: removed; legacy raised [NotImplementedError]{.title-ref}.

  • `BlockingConnection.add_backpressure_callback`: not supported

  • `BlockingConnection.set_backpressure_multiplier`: not supported

  • `BlockingChannel.add_on_flow_callback`: not supported; per docstring in channel.py: "Note that newer versions of RabbitMQ will not issue this but instead use TCP backpressure".

  • `BlockingChannel.flow`: not supported

  • `BlockingChannel.force_data_events`: removed as it is no longer necessary following redesign of the adapter.

  • Removed the [nowait]{.title-ref} parameter from [BlockingChannel]{.title-ref} methods, forcing [nowait=False]{.title-ref} (former API default) in the implementation; this is more suitable for the blocking nature of the adapter and its error-reporting strategy; this concerns the following methods: [basic_cancel]{.title-ref}, [confirm_delivery]{.title-ref}, [exchange_bind]{.title-ref}, [exchange_declare]{.title-ref}, [exchange_delete]{.title-ref}, [exchange_unbind]{.title-ref}, [queue_bind]{.title-ref}, [queue_declare]{.title-ref}, [queue_delete]{.title-ref}, and [queue_purge]{.title-ref}.

  • `BlockingChannel.basic_cancel`: returns a sequence instead of None; for a [no_ack=True]{.title-ref} consumer, [basic_cancel]{.title-ref} returns a sequence of pending messages that arrived before broker confirmed the cancellation.

  • `BlockingChannel.consume`: added new optional kwargs [arguments]{.title-ref} and [inactivity_timeout]{.title-ref}. Also, raises ValueError if the consumer creation parameters don't match those used to create the existing queue consumer generator, if any; this happens when you break out of the consume loop, then call [BlockingChannel.consume]{.title-ref} again with different consumer-creation args without first cancelling the previous queue consumer generator via [BlockingChannel.cancel]{.title-ref}. The legacy implementation would silently resume consuming from the existing queue consumer generator even if the subsequent [BlockingChannel.consume]{.title-ref} was invoked with a different queue name, etc.

  • `BlockingChannel.cancel`: returns 0; the legacy implementation tried to return the number of requeued messages, but this number was not accurate as it didn't include the messages returned by the Channel class; this count is not generally useful, so returning 0 is a reasonable replacement.

  • `BlockingChannel.open`: removed in favor of having a single mechanism for creating a channel ([BlockingConnection.channel]{.title-ref}); this reduces maintenance burden, while improving reliability of the adapter.

  • `BlockingChannel.confirm_delivery`: raises UnroutableError when unroutable messages that were sent prior to this call are returned before we receive Confirm.Select-ok.

  • [BlockingChannel.basic_publish: always returns True when delivery confirmation is not enabled (publisher-acks = off); the legacy implementation returned a bool in this case if `mandatory=True]{.title-ref} to indicate whether the message was delivered; however, this was non-deterministic, because Basic.Return is asynchronous and there is no way to know how long to wait for it or its absence. The legacy implementation returned None when publishing with publisher-acks = off and [mandatory=False]{.title-ref}. The new implementation always returns True when publishing while publisher-acks = off.

\`BlockingChannel.publish\`: a new alternate method (vs. [basic_publish]{.title-ref}) for

:   publishing a message with more detailed error reporting via
    UnroutableError and NackError exceptions.

  • `BlockingChannel.start_consuming`: raises pika.exceptions.RecursionError if called from the scope of a [BlockingConnection]{.title-ref} or [BlockingChannel]{.title-ref} callback.

  • `BlockingChannel.get_waiting_message_count`: new method; returns the number of messages that may be retrieved from the current queue consumer generator via [BasicChannel.consume]{.title-ref} without blocking.

0.9.13 - 2013-05-15

0.9.13

Major Changes

  • IPv6 Support with thanks to Alessandro Tagliapietra for initial prototype
  • Officially remove support for <= Python 2.5 even though it was broken already
  • Drop pika.simplebuffer.SimpleBuffer in favor of the Python stdlib collections.deque object
  • New default object for receiving content is a "bytes" object which is a str wrapper in Python 2, but paves way for Python 3 support
  • New "Raw" mode for frame decoding content frames (#334) addresses issues #331, #229 added by Garth Williamson
  • Connection and Disconnection logic refactored, allowing for cleaner separation of protocol logic and socket handling logic as well as connection state management
  • New "on_open_error_callback" argument in creating connection objects and new Connection.add_on_open_error_callback method
  • New Connection.connect method to cleanly allow for reconnection code
  • Support for all AMQP field types, using protocol specified signed/unsigned unpacking

Backwards Incompatible Changes

  • Method signature for creating connection objects has new argument "on_open_error_callback" which is positionally before "on_close_callback"
  • Internal callback variable names in connection.Connection have been renamed and constants used. If you relied on any of these callbacks outside of their internal use, make sure to check out the new constants.
  • Connection._connect method, which was an internal only method is now deprecated and will raise a DeprecationWarning. If you relied on this method, your code needs to change.
  • pika.simplebuffer has been removed
