Class IndexRecovery

java.lang.Object
  java.lang.Thread
      org.egothor.dir.IndexRecovery

All Implemented Interfaces:

java.lang.Runnable

public class IndexRecovery
extends java.lang.Thread

This class is called everytime a check for crashed client thread is needed. It locks an index directory and rollbacks everyone that crashed in that directory.

- Readers cannot do any damage, so only their read lock is deleted.

- Modifiers cannot do any damage either, their data is deleted.

- Commiters may have caused some damage - all their new barrels are deleted, so no append nor removeDoc is preserved. All local data is deleted too. The index should be in previous consistent state.
