tidwall 9d9c2b9aeb Optimization for non-cross geofence detection ... This commit fixes a performance issue with the algorithm that determines with geofences are potential candidates for notifications following a SET operation. Details Prior to commit b471873 (10 commits ago) there was a bug where the "cross" detection was not firing in all cases. This happened because when looking for candidates for "cross" due to a SET operation, only the geofences that overlapped the previous position of the object and the geofences that overlapped the new position where searched. But, in fac, all of the geofences that overlapped the union rectangle of the old and new position should have been searched. That commit fixed the problem by searching a union rect of the old and new positions. While this is an accurate solution, it caused a slowdown on systems that have big/wild position changes that might cross a huge number of geofences, even when those geofences did not need actually need "cross" detection. The fix With this commit the geofences that have a "cross" detection are stored in a seperated tree from those that do not. This allows for a hybrid of the functionality prior and post b471873.
