An AMQP 1.0 client library for Python.

Disclaimer

uAMQP for Python requires Python 3.6+ starting from v1.5, and Python 2.7 is no longer supported. If Python 2.7 is required, please install uAMQP v1.4.3:

.. code:: shell

$ pip install uamqp==1.4.3

Installation

Wheels are provided for most major operating systems, so you can install directly with pip:

.. code:: shell

$ pip install uamqp

If you are running a Linux distro that does not support ManyLinux1 <https://www.python.org/dev/peps/pep-0513>__ or you need to customize the build based on your system settings and packages, you can install from source:

.. code:: shell

$ apt-get update
$ apt-get install -y build-essential libssl-dev uuid-dev cmake libcurl4-openssl-dev pkg-config python3-dev python3-pip
$ pip3 install uamqp --no-binary :all:

If you are running Alpine, you can install from source:

.. code:: shell

$ apk add --update python3 py-pip python3-dev cmake gcc g++ openssl-dev build-base
$ pip3 install uamqp --no-binary :all:

If you are running Red Hat, you can install from source:

.. code:: shell

$ yum install cmake gcc gcc-c++ make openssl-devel python3-devel
$ pip3 install uamqp --no-binary :all:

Documentation +++++++++++++ Reference documentation can be found here: docs.microsoft.com/python/api/uamqp/uamqp <https://docs.microsoft.com/python/api/uamqp/uamqp>__.

Developer Setup

In order to run the code directly, the Cython extension will need to be build first.

  • Windows: Setup a build environment <https://packaging.python.org/guides/packaging-binary-extensions/#building-binary-extensions>__.
  • Linux: Install dependencies as descriped above in the installation instructions.
  • MacOS: Install cmake using Homebrew:

.. code:: shell

$ brew install cmake

Building the extension ++++++++++++++++++++++

This project has two C library dependencies. They are vendored in this repository in these versions:

  • Azure uAMQP for C <https://github.com/Azure/azure-uamqp-c>__ @ 2021-11-16 <https://github.com/Azure/azure-uamqp-c/tree/259db533a66a8fa6e9ac61c39a9dae880224145f>__
  • Azure C Shared Utility <https://github.com/Azure/azure-c-shared-utility>__ @ 2021-11-15 <https://github.com/Azure/azure-c-shared-utility/tree/735be16a943c2a9cbbddef0543f871f5bc0e27ab>__

To build, start by creating a virtual environment and installing the required Python packages:

.. code:: shell

$ python -m venv env
$ env/Scripts/activate
(env)$ pip install -r dev_requirements.txt

Next, run the build command:

1.0.0 (2018-08-20) ++++++++++++++++++

  • API settled.

  • Behaviour change When a SendClient or SendClientAsync is shutdown, any remaining pending messages (that is messages in the states WaitingToBeSent and WaitingForSendAck) will no longer be cleared, but can be retrieved from a new attribute SendClient.pending_messages in order to be re-processed as needed.

  • Behaviour change The function SendClient.queue_message now allows for queueing multiple messages at once by simply passing in additional message instances:

    • send_client.queue_message(my_message)
    • send_client.queue_message(message_1, message_2, message_3)

  • Breaking change Removed detach_received callback argument from MessageSender, MessageReceiver, MessageSenderAsync, and MessageReceiverAsync in favour of new error_policy argument.

  • Added ErrorPolicy class to determine how the client should respond to both generic AMQP errors and custom or vendor-specific errors. A default policy will be used, but a custom policy can be added to any client by using a new error_policy argument. Value must be either an instance or subclass of ErrorPolicy.

    • The error_policy argument has also been added to MessageSender, MessageReceiver, Connection, and their async counterparts to allow for handling of link DETACH and connection CLOSE events.
    • The error policy passed to a SendClient determines the number of message send retry attempts. This replaces the previous constants.MESSAGE_SEND_RETRIES value which is now deprecated.
    • Added new ErrorAction object to determine how a client should respond to an error. It has three properties: retry (a boolean to determine whether the error is retryable), backoff (an integer to determine how long the client should wait before retrying, default is 0) and increment_retries (a boolean to determine whether the error should count against the maximum retry attempts, default is True). Currently backoff and increment_retries are only considered for message send failures.
    • Added VendorConnectionClose and VendorLinkDetach exceptions for non-standard (unrecognized) connection/link errors.

  • Added support for HTTP proxy configuration.

  • Added support for running async clients synchronously.

  • Added keep-alive support for connection - this is a background thread for a synchronous client, and a background async function for an async client. The keep-alive feature is disabled by default, to enable, set the keep_alive_interval argument on the client to an integer representing the number of seconds between connection pings.

  • Added support for catching a Connection CLOSE event.

  • Added support for Connection.sleep and ConnectionAsync.sleep_async to pause the connection.

  • Added support for surfacing message disposition delivery-state (with error information).

  • Added constants.ErrorCodes enum to map standard AMQP error conditions. This replaces the previous constants.ERROR_CONNECTION_REDIRECT and constants.ERROR_LINK_REDIRECT which are now both deprecated.

  • Added new super error AMQPError from which all exceptions inherit.

  • Added new MessageHandlerError exception, a subclass of AMQPConnectionError, for Senders/Receivers that enter an indeterminate error state.

  • MessageException is now a subclass of MessageResponse.

  • Added ClientMessageError exception, a subclass of MessageException for send errors raised client-side.

  • Catching Link DETACH event will now work regardless of whether service returns delivery-state.

  • Fixed bug where received messages attempting to settle on a detached link crashed the client.

  • Fixed bug in amqp C DescribedValue.

  • Fixed bug where client crashed on deallocating failed management operation.

0.1.1 (2018-07-14) ++++++++++++++++++

  • Removed circular dependency in Python 3.4 with types.py/utils.py
  • When a header properties is not set, returns None rather than raising ValueError.
  • Fixed bug in receiving messages with application properties.

  • Breaking change Submodule async has been renamed to the internal _async. All asynchronous classes in the submodule can now be accessed from uamqp or uamqp.authentication directly.

  • Breaking change Anything returned by a callback supplied to receive messages will now be ignored.

  • Breaking change Changed message state enum values:

    • Complete -> SendComplete
    • Failed -> SendFailed
    • WaitingForAck -> WaitingForSendAck

  • Added new message state enum values:

    • ReceivedUnsettled
    • ReceivedSettled

  • Breaking change Changes to message settlement exceptions:

    • Combined the AbandonMessage and DeferMessage exceptions as MessageModified to be in keeping with the AMQP specification.
    • Renamed AcceptMessage to MessageAccepted.
    • Renamed RejectMessage to MessageRejected which now takes condition and description arguments rather than message.

  • Added errors.LinkDetach exception as new subclass of AMQPConnectionError as a wrapped for data in a Link DETACH dispostition.

  • Added errors.LinkRedirect as a specific subclass of LinkDetach to decode the specific redirect fields of a Link Redirect response.

  • Added errors.MessageAlreadySettled exception for operations performed on a received message that has already returned a receipt dispostition.

  • Added errors.MessageReleased exception.

  • Added errors.ErrorResponse exception.

  • A received Message can now be explicitly settled through a set of new functions on the message:

    • Message.accept()
    • Message.reject(condition:str, description:str)
    • Message.release()
    • Message.modify(failed:bool, deliverable:bool, annotations:dict)

  • Added explicit auto_complete argument to ReceiveClient and ReceiveClientAsync. If auto_complete is set to False then all messages must be explicitly "accepted" or "rejected" by the user otherwise they will timeout and be released. The default is True, which is the exiting behaviour for each receive mechanism:

    • Received messages processed by callback (ReceiveClient.receive_messages()) will be automatically "accepted" if no explicit response has been set on completion of the callback.
    • Received messages processed by batch (ReceiveClient.receive_message_batch()) will by automatically "accepted" before being returned to the user.
    • Received messages processed by iterator (ReceiveClient.receive_message_iter()) will by automatically "accepted" if no explicit response has been set once the generator is incremented.

  • Added new methods to clients and connections to allow to redirect to an alternative endpoint when a LinkRedirect exception is raised. The client redirect helper cannot be used for clients that use a shared connection - the clients must be closed before the connection can be redirected. New credentials must be supplied for the new endpoint. The new methods are:

    • uamqp.Connection.redirect(redirect_info, auth)
    • uamqp.async.ConnectionAsync.redirect_async(redirect_info, auth)
    • uamqp.SendClient.redirect(redirect_info, auth)
    • uamqp.ReceiveClient.redirect(redirect_info, auth)
    • uamqp.async.SendClientAsync.redirect_async(redirect_info, auth)
    • uamqp.async.ReceiveClientAsync.redirect_async(redirect_info, auth)

  • Added on_detach_received argument to Sender and Receiver classes to pass in callback to run on Link DETACH.

  • Removed automatic char encoding for strings of length 1, and added types.AMQPChar for explicit encoding.

  • Bumped uAMQP C version to 1.2.5

  • Bumped Azure C Shared Utility to 1.1.5
