Bug #1005: Strange behaviour of File.directory? under Windows

• Status: Closed
• Assignee: nobu (Nobuyoshi Nakada)

Under Windows:
C:>ruby --version
ruby 1.8.7 (2008-08-11 patchlevel 72) [i386-mswin32]
C:>irb
irb(main):001:0> File.directory? ".."
=> true
irb(main):002:0> File.directory? "..."
=> true
irb(main):003:0> File.directory? ".............."
=> true

Under Unix:

ruby --version

ruby 1.8.5 (2006-08-25) [i386-linux]

irb

irb(main):001:0> File.directory? ".."
=> true
irb(main):002:0> File.directory? "..."
=> false
irb(main):003:0> File.directory? "........"
=> false

I.e. it looks like File.directory? returns true under Windows if filename contains any number of dots.

Sorry, could'n test this exact Ruby version under Unix.

If it's a bug, it's a bug in the Windows API:

irb(main):001:0> require 'windows/path'
=> true
irb(main):002:0> include Windows::Path
=> Object
irb(main):003:0> PathIsDirectory('.')
=> true
irb(main):004:0> PathIsDirectory('..')
=> true
irb(main):005:0> PathIsDirectory('...')
=> true
irb(main):006:0> PathIsDirectory('.......')
=> true
=end

What API does the PathIsDirectory method use,
GetFileAttributes()?

I'm not sure, but I believe so.
