py-amqplib / CHANGES

Version 0.6.2-devel

    Add an 'encoding' parameter to AMQPWriter.write_shortstr() and
    AMQPReader.read_shortstr() in serialization.py, the default
    value of 'utf-8' gives the same behavior as before.

Version 0.6.1

    One minor change to watch out for is that low-level errors
    such as a closed connection now appear as IOExceptions
    instead of

        TypeError: 'NoneType' object is not iterable

    which never really explained anything.

    Fix potential problem with library getting stuck in a loop
    if the peer closed the socket.  Also, break a few more references
    when closing Connections and Channels, to help garbage collection.
    Thanks for majek04@... for pointing these out.

    Add support for using Connection and Channel objects as context
    managers for 'with' statements (available in Python >= 2.5), so you
    can write code like:

        with Connection() as conn:
            with conn.channel() as ch:
                # do stuff with ch and conn

    and have the Channel and Connection objects closed automatically
    when the blocks exit.

Version 0.6

    Very large rearrangement of code, breaking the large client_0_8.py
    module into submodules based on the various layers of the AMQP protocol.
    The public API is unchanged however, so existing code that uses amqplib
    should be unaffected.


    nb_client_0_8.py and demos/nbdemo_receive.py were removed because of
    the major changes to the main client to lay the groundwork for future
    non-blocking behaviors (see http://hg.barryp.org/py-amqplib-devel/ )


    More unittests added.

Version 0.5

    Get rid of Python 2.5-style conditional expressions, for
    compatibility with Python 2.4  Thanks to Alexey Timanovsky
    for pointing this out.

    Send debugging output through the standard Python 'logging' module
    instead of directly printing to the console.

    Reworked the guts of the Connection and Channel classes
    to untangle the mess that controlled how frames were
    waited for and queued up.  Should fix problems seen with
    basic_deliver messages coming when the client is expecting
    responses to other synchronous calls.

    Added non-blocking client and demo, from
    Dmitriy Samovskiy <dmitriy.samovskiy@cohesiveft.com>:
        We put together an add-on for py-amqplib that implements AMQP client
        with non-blocking sockets (see NonBlockingConnection class and
        nbloop() function in nbclient_0_8.py). nbdemo_receive.py is a demo
        script, and nbclient.zip includes both nbclient_0_8.py and

        There are at least 2 scenarios where non-blocking sockets help, and
        both are applicable to consumers:

        1) when you want to be able to interrupt consumer's event loop
           without waiting for a next incoming message;
        2) when you want to consume messages from multiple brokers (or over
           multiple connections) in a single event loop.

    Did some profiling, found a big problem that caused a huge huge
    number of unnecessary __getattr_ calls.  Ran pylint and found some
    bad coding style problems.

Version 0.3

    Improved skeleton generating program to include much more
    information in the Python docstrings that was present in the AMQP
    spec file. Merged in the improved docstrings into the client module.

    After having a better look now at the pydocs, it turns out that in
    several methods, a default value of '' can be used for queue names
    and exchange names, so update method signatures to take advantage of

    Channel.queue_bind() can also take '' as a queue parameter, but
    unfortunately we can't set that as a default value because
    the exchange parameter can't have a default value.  In hindsight
    those args should have been swapped, but it's too late now.

    Deal with no callback being specified in basic_consume(), it
    should now quietly discard messages.

Version 0.2

    Changed the default value for the auto_delete parameter
    in the Channel.exchange_declare and Channel.queue_declare
    methods to True.

    Added an 'insist' parameter to the Connection class
    constructor, defaulting to False.  Setting it to True
    indicates to the AMQP server that you don't want to
    be redirected (you're insisting to connect to the
    specified server).

    Added support for being redirected to another AMQP
    server when a Connection is opened.

    Added tests/fake_redirect_0_8.py to help with testing
    redirect support.

Version 0.1
