Description

dCache puts a zero length file in /pnfs when the transfer command starts, and it can then stay there for an extended period without the timestamps changing until the transfer completes.

I've made it so zero length files are skipped by the scanner. It'll finally pick them up once the dCache transfer has completed.

Implemented in e4d6b8ff

This also simplifies the directory caching logic, which should close a few races that could cause it to miss certain files.
