Justin Ross commented on QPID-2453:
-----------------------------------
Ernie, I think this one needs to go to review board. I looked at it, and I
have two uncertainties: (1) is that the best way to filter the exceptions? and
(2) is the name "nonblocking" right in this context?
> Python messaging client unusable after receiving a malformed message
> --------------------------------------------------------------------
>
> Key: QPID-2453
> URL: https://issues.apache.org/jira/browse/QPID-2453
> Project: Qpid
> Issue Type: Bug
> Components: Python Client
> Reporter: Ted Ross
> Attachments: python-tests.patch, qpid-2453.patch, test.py
>
>
> Description of problem:
> This bug is in reference to the new messaging API.
> If the Python messaging client (qpid.messaging) receives a message which is
> in any way malformed (i.e. improper UTF8 encoding in strings, unknown
> content-type), it throws an exception on the receiver.fetch call. From this
> point forward, the API is unusable. Any attempt to recover or call methods
> in the API (session.close, connection.close, fetch on other receivers, etc.)
> will result in the same exception repeating itself.
> Version-Release number of selected component (if applicable):
> Development trunk.
> How reproducible:
> 100%
> Steps to Reproduce:
> 1. Produce a message with a content-type of "amqp/xxx"
> 2. Send this message to a queue
> 3. Set up a receiver to receive the message from the queue
> 4. Call fetch on the receiver
> Actual results:
> An exception is thrown and subsequent calls repeat the exception (i.e. trying
> to close the receiver, session, or connection). The only way out is to kill
> the client process.
> Expected/Desired results:
> The malformed messages should be received normally. Perhaps there should be a
> "malformed" flag on the message that can be checked, or an exception should be
> thrown when attempting to access the content of the message.
> In no case should this cause an unrecoverable condition.
