Gordon Sim updated QPID-3653:
-----------------------------
Fix Version/s: (was: 0.15)
> QMF Python API inappropriately enforces schema
> ----------------------------------------------
>
> Key: QPID-3653
> URL: https://issues.apache.org/jira/browse/QPID-3653
> Project: Qpid
> Issue Type: Bug
> Components: Qpid Managment Framework
> Affects Versions: 0.12
> Environment: Fedora 15, not that it matters.
> Reporter: Zane Bitter
> Assignee: Ted Ross
> Priority: Minor
>
> When calling a method from the Python QMF API, the number of arguments
> provided is checked against the schema and an exception raised if they do not
> match. This means that there is no way to update a schema (e.g. by adding
> new, optional parameters to a command) without also breaking existing Python
> console scripts.
> Note that the C++ implementation has no such restriction, so there is no
> technical reason for it.
> This check should be removed for the case where there are fewer arguments
> provided than specified by the schema. The checking of keyword arguments is
> currently pretty limited - e.g. they may overlap with positional arguments,
> or may be for fields not present in the schema (in both cases they are
> ignored).
> Ideally, additional keyword arguments beyond the ones present in the schema
> should also be allowed (this _appears_ to be possible; I don't see the schema
> being used to identify the parameter's type, so I assume it is inferred).
> This would allow new scripts to continue to talk to both new and old agents
> without having to check the schema.
