| Re: [p2-dev] why is it not enough to just listen for removed files |
The DirectoryWatcher does not track file deletions between runs. e.g. "scannedFiles" is computed based on the current run and is not persisted.
The RepositoryListener on the other-hand does perists ius/artifact descriptors between runs so needs to verify everything in its repo is polled/on disk.
I'm a bit undecided if it's better to track persistence in a listener or in a specialized directory watcher but for now we're doing it in a listener. We could factor that out to a common listener super class fairly easily.
