- Fixed various bugs in the RTree concurrency control protocol which caused some searchers to miss some nodes due to concurrent splits. - Fixed a bug in the unordered slot manager, and also reduced number of copy operations in the process of splitting a node. - Fixed a bug in the LSMRTree search cursor that causes deadlocks due to incorrect BTree cursors resets. - Fixed a minor bug in the LSMRTree merge. - Applied the new file naming scheme for LSMRTree based on timestamp intervals. - Added RTree and LSMRTree multi-threading test framework. - Some code refactoring in the RTree frames. - Code cleaning.

Implemented registration of LSM components via atomic renaming of a temp component. Modified LSMFileNameManager to use IOManager, such that new LSM components are written to IODevices in a round rob in fashion. Added tests using multiple IO devices.

  1. … 37 more files in changeset.
Implemented new file naming scheme for LSM indexes based on timestamp intervals. Relying on the file names alone, an LSM index can always determine whether an LSM component is valid or not. Still TODO: Implement flushing/merging into a temp file, followed by an atomic rename upon success.

- Added LSMRTree test framework. - Fixed a bug in the UnorderedSlotManager that caused the delete operation to fail when number of fields in the search key does not match number of fields in the tree. - Code cleaning.
