This is still an issue in the master branch. One way to fix this is to delete the autoload if the constant isn't present after the file is loaded. I submitted a pull request for that: https://github.com/ruby/ruby/pull/4715 ---------------------------------------- Bug #15790: Strange interaction between autoload and $LOADED_FEATURES https://bugs.ruby-lang.org/issues/15790#change-93154 * Author: fxn (Xavier Noria) * Status: Open * Priority: Normal * ruby -v: ruby 2.6.1p33 (2019-01-30 revision 66950) [x86_64-darwin18] * Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- If an autoload fails and we remove its associated file from `$LOADED_FEATURES`, the autoload is back: ``` $ cat x.rb Y = 1 # should be X, emulates a typo $ cat test.rb def au Object.autoload?(:X).inspect end x_rb = File.realpath("x.rb") autoload :X, x_rb puts "before failed autoload autoload path is #{au}" X rescue nil puts "after failed autoload autoload path is #{au}" $LOADED_FEATURES.delete(x_rb) puts "after $LOADED_FEATURES deletion autoload path is #{au}" ``` The output is ``` $ ruby -v test.rb ruby 2.6.1p33 (2019-01-30 revision 66950) [x86_64-darwin18] before failed autoload autoload path is "/Users/fxn/tmp/x.rb" after failed autoload autoload path is nil after $LOADED_FEATURES deletion autoload path is "/Users/fxn/tmp/x.rb" ``` See? Last line would be expected to print a `nil` autoload path. -- https://bugs.ruby-lang.org/ Unsubscribe:
