Ted Ross commented on QPID-3046:
--------------------------------
There has been discussion about moving the QMF code out of the main source tree
and into the "extras" tree. This is appropriate in that QMF is, as of v2,
completely layered over messaging and does not require anything in the
messaging broker beyond standard AMQP 0-10 behavior. I suggest raising a
separate Jira for this effort because it will not be done in the Qpid 0.10
timeframe. Note that the pure Python implementation of QMF is already in the
extras tree.
The primary reason that the C++ implementation cannot yet be moved out of the
main tree is that it uses non-public Qpid headers:
1) It uses the qpid::sys namespace for locks, conditions, and other wrapped OS
features.
2) It uses the qpid::framing namespace (specifically Buffer and FieldTable) to
construct and interpret QMFv1 messages for backward compatibility.
Some possible approaches to consider:
1) Move qpid::sys out of the main tree as it is also not messaging specific but
more of a general-purpose OS abstraction layer.
2) Provide a binary codec that puts AMQP-typed values into a buffer in-order
without map or list overhead
3) Fully deprecate QMFv1 (i.e. abandon backward compatibility)
> QMFv2 Completion and Cleanup

> Key: QPID-3046
> URL: https://issues.apache.org/jira/browse/QPID-3046
> Project: Qpid
> Issue Type: New Feature
> Components: Qpid Managment Framework
> Reporter: Ted Ross
> Assignee: Ted Ross
> Fix For: 0.9
>
>
> This feature is for the completion of the QMFv2 implementation and language
> bindings (C++, Python, Ruby). This also includes cleanup and removal of
> stale code.
> In this deliverable:
> 1) New QMFv2 implementation in C++ with ABI-stable interface in the same
> pattern as the stable messaging API.
> 2) A Python binding to the API
> 3) A Ruby binding to the API
> 4) Support for QMFv2 formatted queries and methods in the broker agent
> (available in the C++ broker, not yet implemented in the Java broker)
> 5) Documentation
