Subject: [ruby-core:62053] [ruby-trunk - Bug #7822] Dir.mkdir can't handle long Windows Unicode paths (\\?\UNC\)

Issue #7822 has been updated by Eric Loveland.


I would recommend that this bug be closed.  However, I have not found any feature requests for better support of "\\\\?\\".  Is it worth submitting one or would this be better handled with a gem?

Code:
  Dir.mkdir "//?/C:/" + "test" * 100

What I expected:
  Ruby will create directory //?/C:/testtesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttest, judging from http://msdn.microsoft.com/en-us/library/aa365247.aspx

What happened on the second call:
  Errno::ENOENT: No such file or directory - //?/C:/testtesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttest
          from (irb):6:in `mkdir'
