I deleted my previous comment, misunderstood the situation. Yeah, in my view if you fire an autoload, the autoload should be removed regardless of the outcome. Additionally, if the constant has not been defined, it should be removed (as undefined) too. ---------------------------------------- Bug #15790: Strange interaction between autoload and $LOADED_FEATURES https://bugs.ruby-lang.org/issues/15790#change-93165 * Author: fxn (Xavier Noria) * Status: Open * Priority: Normal * ruby -v: ruby 2.6.1p33 (2019-01-30 revision 66950) [x86_64-darwin18] * Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- If an autoload fails and we remove its associated file from `$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:
