Can't create a client against icat.server 6.1.0-SNAPSHOT: icat.exception.ICATParameterError: Parameter is not an ICAT entity

[louise-davies]

Hello,

The new icat.server snapshot (6.1.0-SNAPSHOT) no longer works with python-icat, when trying to create a client we get an error from getEntityInfo: icat.exception.ICATParameterError: Parameter is not an ICAT entity. @ajkyffin has pointed out that python-icat queries for the entity info of the "Parameter" entity, which isn't a real entity in icat.server (see /~https://github.com/icatproject/python-icat/blob/develop/src/icat/entities.py#L253). The commit on icat.server which changed what is returned from getEntityInfo is here: icatproject/icat.server@7420ced

Alan could modify icat.server to return entity info for "Parameter" to keep in line with old behaviour, but that seems like the wrong thing to do and instead we should not expect to have "Parameter" be valid for getting entity info

But then, this change in icat.server is a breaking change that should be discussed in the community and certainly not be made in a minor release.

My intention was not to make any breaking changes so I'll add back the ability to get entity info for Parameter into icat.server.

I guess, we can discuss this in the collaboration meeting next week.

In the meanwhile, I mark this one with question tag, pending this discussion.

As discussed in the collaboration meeting this week, icat.server will for the time being continue to deliver entity info for the abstract class Parameter. There is thus no need to change python-icat in this point.
