Description

« Hide

FileTest methods in MRI work on filename strings or File objects, but in JRuby they only work with strings.

dudley@hiro jruby-trunk :> irb
>> FileTest.size(File.new('x','w+'))
=> 0

dudley@hiro jruby-trunk :> jirb
>> FileTest.size(File.new('x','w+'))
TypeError: can't convert File into String

Here's a patch that works for the specific case where you're passing in a File object (or anything that responds_to "path"). MRI calls to_io and then fstat on the IO object's file descriptor, so this isn't 100% compatible, but it is slightly closer than just accepting strings.

Confirmed, this is still broken. I think the approach we need is to add specs for where to_io is supposed to be called to the rubyspecs and fix from there. No one-shot hacks, sorry

Marking as broken in 1.1.1 to keep it fresh.
