Subject: [ruby-core:55570] [ruby-trunk - Bug #8547] FileUtils.chmod("a+r", "foobar", verbose: true) crashes


Issue #8547 has been updated by robotmay (Robert May).


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 :)

Bug #8547: FileUtils.chmod("a+r", "foobar", verbose: true) crashes
https://bugs.ruby-lang.org/issues/8547#change-40064

Author: gurgeous (Adam Doppelt)
Status: Open
Priority: Normal
Assignee: 
Category: 
Target version: 
ruby -v: ruby 2.0.0p195
Backport: 1.9.3: DONTNEED, 2.0.0: REQUIRED


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.
