Gordon Sim resolved QPID-2714.
------------------------------
Resolution: Fixed
> "Programming in Apache Qpid" doesn't discuss capacity/credit
> ------------------------------------------------------------
>
> Key: QPID-2714
> URL: https://issues.apache.org/jira/browse/QPID-2714
> Project: Qpid
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 0.7
> Reporter: Steve Huston
> Priority: Minor
> Attachments: QPID-2714.patch
>
>
> My comments grew out of looking at the C++ messaging API, though this
> probably applies to Python and .NET as well.
> During a discussion on users@qpid I initiated recently I learned that
> creating a number of Receivers and calling session.nextReceiver() to wait for
> a message on any of the Receivers doesn't work unless some capacity is
> granted to the Receivers first. This is different from simply calling fetch()
> on a Receiver with no capacity - in that case the client code issues credit
> behind the scenes.
> The code example shown in section 6 won't work (I used something very similar
> in a program I wrote, and it didn't for the reason above). I'll attach a
> patch that fixes the C++ code example, but there should be an
> introduction/discussion of the whole topic of capacity, credit, acks, etc.
