Status changed from Assigned to Closed Fixed by #7158. See #7387. ---------------------------------------- Feature #5427: Not complex patch to improve `require` time (load.c) https://bugs.ruby-lang.org/issues/5427#change-33138 Author: funny_falcon (Yura Sokolov) Status: Closed Priority: Normal Assignee: nobu (Nobuyoshi Nakada) Category: Target version: 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. https://gist.github.com/1272991 https://github.com/ruby/ruby/pull/51 -- http://bugs.ruby-lang.org/
