Bug #8547: FileUtils.chmod("a+r", "foobar", verbose: true) crashes

• Status: Third Party's Issue
• Assignee: -
• Target version: -
• ruby -v: ruby 2.0.0p195

[gurgeous (Adam Doppelt)]

To reproduce in IRB:

require "fileutils" ; FileUtils.chmod("a+r", "foobar", verbose: true)

Here's the stack:

NoMethodError: undefined method mode_to_s' for FileUtils:Module from ~/.rbenv/versions/2.0.0-p195/lib/ruby/2.0.0/fileutils.rb:970:in chmod'

This ONLY crashes with :verbose. If you leave off :verbose it skips the call to mode_to_s, so there's no crash.

I submitted a pull request on the GitHub mirror which fixes the issue. Whether it's the correct fix I can't be certain, as I've not submitted code to Ruby core before :)

Seems there is no tests for module methods.

I guess it was fixed at r41853 before v2_1_0_preview1 and backported to ruby2_0_0 at r41946 [Backport #8633].
