[rubygems/rubygems] Ignore internal frames in RubyGems' Kernel#warn
* See * `<internal:` is a common prefix also used by core Ruby files in CRuby. * test_no_kernel_require_in_*warn_with_uplevel already test this. * Unfortunately just skipping `<internal:` in the Ruby implementation is not enough, because RubyGems' #warn would not skip the `<internal:` require (TruffleRuby defines #require in Ruby), and the Ruby implementation's #warn would not skip RubyGems's #require. The #caller_locations(0) look like this: warnee.rb:1:in `<top (required)>' # where #warn is called <internal:core> core/kernel.rb:234:in `gem_original_require' # not skipped by RubyGems' warn, skipped by the Ruby impl rubygems/core_ext/kernel_require.rb:54:in `require' # not skipped by the Ruby impl's warn, what would be shown without this fix warn.rb:1:in `<main>' # what would be correct warn.rb is require "warnee" warnee.rb is puts caller_locations(0), nil warn "oops", uplevel: 1
