Dir#glob and escaped commas

[robin850]

Hello,

Dealing with a glob wrapped inside braces and a folder name containing commas, JRuby will ignore the escaping on commas and consider that the glob is in two parts so for instance, in the following example, JRuby will search for text files on the whole disk :

>> glob = '{i\,dont\,exist\,/**/*.txt}';

>> RUBY_ENGINE
=> "jruby"
>> Dir[glob]
=> ["/install.txt", "/etc/urls.txt", ...]

>> RUBY_ENGINE
=> "ruby"
>> Dir[glob]
=> []

For the record, this makes this test to fail in the Ruby on Rails test suite as searching files on the whole disk takes time and the Thread running this statement only has 5 seconds to run.

A RubySpec has been added for that in rubyspec/rubyspec#281.

Have a nice day.
