Feature #8158

lightweight structure for loaded features index

Added by Yura Sokolov over 2 years ago. Updated almost 2 years ago.

Assignee:Nobuyoshi Nakada


Use lightweight structure for loaded_features index:

  • use hand made simple hash structure, which uses only one memory chunk,
  • do not store feature name string, only hash of it, since loaded_feature_path will recheck feature name on hash collision
  • use single linked lists instead of arrays for storing features indices.
  • store this lists inside one array, using array's indices as a reference.

While startup speedup improvement is relatively small compared current implementation,
this one does not need any Ruby Objects at all, so that there is no presure on GC.
