When I try to open a controller of mine, I get this error:
The slot ELEPHANT::INSTANCE-TABLE is unbound in the object
#<BDB-STORE-CONTROLLER ...>
It seems that this is caused by a bug with how the instance-table is
established in a new controller, since the stack trace indicates this
bug occurs when the INSTANCE-TABLE slot is being set up.
Specifically, at this line in bdb-controller.lisp:
(setf (slot-value sc 'instance-table)
(if (or new-p (elephant::prior-version-p
(database-version sc) '(0 9 1)))
;; When opening the DB equal or prior to 0.9.1,
always get the indices initialized,
;; regardless of the indices is initialized before.
;; Even the indices is serialized before(in the case
that open the <=0.9.1 DB file for the second time),
;; it still can not be unserialized here, because
its persistent object's oid
;; does not match the hardcoded one in
oid->schema-id, which only work on the DB file
;; created in release > 0.9.1.
(make-instance 'bdb-indexed-btree :from-oid -3 :sc
sc :indices (make-hash-table))
>>>> (make-instance 'bdb-indexed-btree :from-oid -3 :sc sc)))
>>>> <<<<
I will work on a fix now. If anybody has insights, gotchas, etc. let
me know. A patch soon to follow...
The slot ELEPHANT::INSTANCE-TABLE is unbound in the object
