• Status: Closed

[nobu (Nobuyoshi Nakada)]

In general, the feature name registered in $LOADED_FEATURES (e.g. "enumerator.so", "thread.rb", and so on) is expected not to be loaded again.

But, as @ko1 (Koichi Sasada) reported, when a feature name is added to the variable during another file is required, it will be loaded again.

$ echo 'raise __FILE__' > target.rb
$ echo '$" << "target.rb"' > provide.rb
$ ruby -r./provide.rb target.rb 
target.rb:1:in `<main>': target.rb (RuntimeError)

[Bug #18173] Update loaded_features_index

If $LOADED_FEATURES is changed in the just required file, also the
index table needs to be updated before loaded_features_snapshot is
reset. If the snapshot is reset without updating the table, the
name of the added feature will not be found.
