Description

The registry.db files table should have a unique constraint over the id and path columns, shouldn't it? (Or a primary key constraint, since it looks like sqlite does support compound keys that span multiple columns.)

I have a corrupt registry which, after repairing by using .dump and .read, has duplicate entries in the files table. This causes activation of those ports to fail:

/opt/local/etc/select/python2/base is not being used by another port, but it is "owned" by this port three times according to the registry.

I have checked other non-corrupt registries and they do not have any duplicate entries in the files table.

I am guessing that the corruption did not cause the duplicate entries, but that MacPorts got confused by the registry corruption and inserted those duplicate entries while activating, deactivating, installing or uninstalling a port. Whatever the cause of the duplicate entries, a proper unique or primary key constraint would have prevented this incoherent registry state from being created.

Perhaps we need some more primary or unique keys in the other tables too.

If there have been prior discussions about this that I've missed, let me know.
