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 op_depth? 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 change). 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? Bye, Erik.
