ruby -v: ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]


Assuming a directory structure of:

a/b/c/d/e/f/g/h

I am trying to find 'h' via:

Dir.glob('a/**/f/g/h')

However this is not working. Any ideas?

You can try the test case below:

$ /usr/bin/ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
$ mkdir -p a/b/c/d/e/f/g/h
$ ruby -e "puts Dir.glob('a/**/*')"
a/b
a/b/c
a/b/c/d
a/b/c/d/e
a/b/c/d/e/f
a/b/c/d/e/f/g
a/b/c/d/e/f/g/h
$ ruby -e "puts Dir.glob('a/**/h')"
a/b/c/d/e/f/g/h
$ ruby -e "puts Dir.glob('a/**/g/h')"
a/b/c/d/e/f/g/h
$ ruby -e "puts Dir.glob('a/**/f/g/h')"
**nothing**

Issue #6977 has been updated by cyberkni (Dan Van Derveer).


This revision has not been released as of 1.9.3p374 which is a bummer 
since this was fixed quite a while ago.

Is there a reason this hasn't been released?
