I definitely don't want to release until we're comfortable the tests
are covered. We'll look for a reasonable consensus that it is ready.
FYI - The backend updates will require:
- Initialization of new base class slots with fixed-oid btrees
(schema-table :reader controller-schema-table
:documentation "Schema id to schema table, an indexed btree")
(instance-table :reader controller-instance-table
:documentation "Contains indexed btree of oid to class ids")
(index-table :reader controller-index-table
:documentation
"This is another root for class indexing that is
also a data store specific persistent btree instance
with a unique OID that persists between sessions.
No cache is needed because we cache in the class slots.")
- Implement duplicate btrees (allow duplicate keys ordered by key,
value)
- add remove-kv-pair operator to augment remove-kv
- Schema IDs and bootstrapping:
- next-cid (sequence of schema id values)
- specialize oid->schema-id (accounts for reserved oids for the
fixed btrees above)
- default-class-id (map class typename to class schema id)
- default-class-id-type (map class schema id to class type name)
For an examples of the above see bdb-controller and bdb-collections.
I may be forgetting something, but this is the bulk of the needed
changes.

That is really great !
We'll follow with postmodern backend soon. I don't think we should
haste with releases though, it is better if we have the time to
check for bugs and update the test suite. I want to encourage anyone
that sees some areas that are not tested enough to just feed back
this. No one will force you to actually code the tests. I might have
been lazy with elephant for a while, but I might do a comeback and
code some tests or something some day...
Thanks a lot Ian,
super!,
Henrik
