Today, I finished replacing all NODE_DATA queries (UPDATE/DELETE/INSERT) in
wc_db.c by queries which operate on NODES. From here on, I'll start to write
code to query BASE_NODE+NODES and WORKING_NODE+NODES, verifying that both
tables return the same results.

There are however, a few queries in 'entries.c' which operate directly on
BASE_/WORKING_NODE. These queries will need to be migrated. However, in our
old entries, we don't have the concept of op_depths and op roots. That makes
it a bit hard to migrate the entries file to the exact semantics of the
NODES table. When we fix the WORKING_NODE concept to have an op_depth == 1
during migration, however, conversion of the queries in that file isn't much
of a problem.

Does anybody expect serious issues from all working nodes having the same

The alternative would be to set the op_depth of each working node to the
path component count of its local_relpath (making each node a stand-alone

Now that I write the above, I think it's the sanest to make each working
node its own oproot. That would be roughly as simple to code as the
"everything is 1" assumption.

Better ideas? Comments?
