Feature #11140


Allow rubygems' `require` to handle `autoload` calls

Added by tenderlovemaking (Aaron Patterson) over 7 years ago. Updated over 3 years ago.

Target version:


Right now, rubygems can't handle calls to autoload because autoload will directly call rb_require_safe rather than sending to Kernel::require.

For example:

class A
  autoload :B, 'a/b' # this is in a different Gem

The above code won't work because 'a/b' is in a different gem. I'd like to give rubygems the opportunity to handle requires made through autoload.

I've attached a patch that makes the change.

Considering #5653, should we be making any changes to autoload to make it easier to use, if the intention is to remove it in ruby 3.0? I think before any improvements to autoload should be considered, we first need a firm decision from Matz on autoload's future in ruby.

If Matz decides that autoload will stay in ruby, I'm definitely in favor of autoload calling Kernel::require. But if autoload will be removed in ruby 3.0, I don't think we should make changes like this that would make autoload easier to use. That encourages people to use autoload, which will make updating to ruby 3.0 more painful when the time comes.

  • Description updated (diff)

It sounds reasonable as -r option also calls Kernel#require method now.

Accepted. Could you apply the patch, Aaron?

    than directly calling rb_require_safe. This allows things like
    RubyGems to intercept file loading done though autoload.

@usa (Usaku NAKAMURA) I'm looking in to it. It seems to be a bug with looking up activated features during autoload. :(

Since this commit TestAutoload#test_threaded_accessing_constant continuously fails on some Linux distributions.

Any updates?

Is this still failing? I don't see it on
