org.syncany.operations.cleanup.CleanupOperation

The purpose of the cleanup operation is to keep the local database and the remote repository clean -- thereby allowing it to be used indefinitely without any performance issues or storage shortage.

The responsibilities of the cleanup operations include:

Remove old {@link FileVersion} and their corresponding database entities.In particular, it also removes {@link PartialFileHistory}s, {@link FileContent}s, {@link Chunk}s and {@link MultiChunk}s.
Merge metadata of a single client and remove old database version files from the remote storage.

High level strategy:

Lock repo and start thread that renews the lock every X seconds

Find old versions / contents / ... from database

Write and upload old versions to PRUNE file

Remotely delete unused multichunks

Stop lock renewal thread and unlock repo

Important issues: All remote operations MUST check if the lock has been recently renewed. If it hasn't, the connection has been lost. @author Philipp C. Heckel
