Update of /project/elephant/cvsroot/elephant
In directory common-lisp:/tmp/cvs-serv18474

Modified Files:
	TODO config.lisp 
Log Message:

Quick fix for config.lisp not having a package designator.  Also my tweaks
to fix a BDB bug, adding transacctions to btree writes for increased safety
and various tweaks I made trying to fix the slot-boundp bug in indexing-redef-class

+---------
+- Review all the NOTE comments in the code
+- Remove build gensym warnings in sleepycat
+- Port elephant to closer-to-MOP to make it easier to support additional lisps (Both)
+- (From Ben's e-mail) We are storing persistent objects incorrectly. They should be
+  stored only as OIDs, and we should have a separate OID->class table.  This way 
+  change-class can be handled correctly (Ian) ???
+- Delete persistent slot values from the slot store with remove-kv to ensure that
+  there's no data left lying around if you define then redefine a class and add
+  back a persistent slot name that you thought was deleted and it gets the old
+  value
+
+Stores: 
 - Think about dynamic vs. object based store & transaction resolution?
   - Error checking when mixed 
   - Current store specific *current-transaction* stack
-- Throw condition when store spec is invalid, etc
 - Think through default vs. explicit store referencing all over the APIs (Both)
+- Throw condition when store spec is invalid, etc

+Transactionalism:
 - Cleaner failure modes if operations are performed without repository or without
   transaction or auto-commit (Both)
-- Add asserts if *auto-index* is false and we're not in a transaction
-  to help users avoid lockups in bdb?  Should be able to turn off for
-  performance but it will help catch missing with-transaction statemetns
-  in user code. (Both)
