Re: [Kimchi-devel] [PATCH] [Kimchi] Update Kimchi objectstore versioning.
This solution works for Kimchi and Ginger now, but I analyzed it a bit
deeper and I cannot see it as a good long-term solution.
Reasons:
- other plugins will never be allowed to have a column named version in
its table, for whatever reason they want;
- every new record must have the version inserted, today we cannot
measure the impact, but, if for some reason objectstore must be heavily
used, this can impact;
- we will have (or each plugin will have) to change this in future,
because all 'object' tables will have 'version' column, then each plugin
will have to manage by itself how to check and update the records or
schemas;
- finally, I think that Wok should not touch plugins 'objectstore'.
Like I said, this solution works for Kimchi/Ginger now, and I am ok,
once we are running out of time.
But keep in mind , that we are going to have rework in future.
Aline can decide what to do.

This patch is part of the solution for the Ginger Issue #51 and it depends on
Wok's "Upgrade objectstore schema" patch.
With the new structure of the objectstore changed in Wok 2.0.0, the schema of
the objectstore file needs to be checked and, if necessary, updated to reflect
the new structure.
This patch removes from Kimchi the methods used to check the objectstore schema
and upgrade it if necessary. These methods are now present in wok.plugins and
are common to any Wok plugin.
