Issue #5427 has been updated by Yura Sokolov.


Is there any chance for it or something like it to be included in 1.9.3 release?

Feature #5427: Not complex patch to improve `require` time (load.c)
http://redmine.ruby-lang.org/issues/5427

Currently `loaded_features` are unsorted, so that `rb_feature_p` ought to iterate over all `loaded_features` to figure: is requested feature loaded?

After this patch `loaded_features` is kept sorted by basename without extension (/usr/lib/ruby/asdf.rb => asdf). When `rb_feature_p` start its check, it goes straight to the first item with matching basename (using binary search) and stops after last.

Methods `$LOADED_FEATURES.<<` and `$LOADED_FEATURES.push` are overriden to keep sort order. `push` accepts only 1 parameter, but it seems that no one pass more to it.

Currently I choose to consider characters of basename in right to left order, but it could be changed, I think.
