  14. 93bbf99 Fixed a bug (reported by Zack) in the r-tree insert method. The issue turned out to occur when all the objects residing inside an MBR are points that are aligned exactly on the same line causing the area of that MBR to be exactly zero which makes the r-tree think that it does not need to enlarge the MBR if a new object (to be inserted into this node) is also aligned with the MBR line but it does not fall on it. by salsubaiee · 12 years ago

  26. 367564e Allowing LSM file managers to be initialized with a starting IO device index. Using that mechanism, the first disk component of the i-th partition of an Asterix LSM index is written on the i-th IO device (further components are assigned to IO devices in a round robin fashion). by alexander.behm · 12 years ago
  27. 20a817c * The cleanup of the merged components in the LSM indexes is now the responsibility of either: the last existing search thread (in case the merge process is over and there are still search threads accessing the merged components), or the merge thread itself (in case the merge process is over and there are no search threads accessing the merged components). * Allowed concurrent merges to occur at the same time instead of the old design which only allowed one merge process at a time per LSM index. by salsubaiee · 12 years ago

  32. 717e063 Removed two unnecessary methods from the file manager interface. by salsubaiee · 12 years ago
  33. 03b7f53 Refactored the LSM-indexes to use common abstract class. Added new ILSMComponent interface to represents the LSMComponents instead of passing Objects all around the place.

  48. 8611a83 Fixed a bug introduced in r2413 that leadto LSM searches being executed as 'try' operations. This caused searchers not to wait for flushes, which violates our current CC protocol, and ultimately lead to hanging threads. by alexander.behm · 12 years ago
