Hi Cygwin and git developers,

Does following scenario show signs of bugs in Cygwin and/or git?

# setup git repo $ cd /tmp $ mkdir foo && cd foo $ git init

# create x: directory $ mkdir x: $ ls x:

# create Windows X: drive, cygwin utils can work with both unix and dos style # path names $ mkdir c:/temp/bar $ subst x: c:/temp/bar $ touch x:/file.txt $ ls x:/ file.txt

# clean git tree from non-tracked files $ git clean -d -x -f Removing x:/

# observe results, git did rm -rf on the X drive instead of the local # directory named x: $ ls x: $ file x\: x:: directory $ ls x:/ ls: cannot access x:/: No such file or directory $ ls c:/temp/bar ls: cannot access c:/temp/bar: No such file or directory $ subst X:\: => C:\temp\bar

In real life CMake created C: file in a build tree -- which is also a bug but a separate one -- which resulted in obviously catastrophic results.

I would report this on the Cygwin list, not here. Any use of dos file paths using a Cygwin tool is not recommended, officially only POSIX paths are supported. If cygwin's Cmake is generating dos style paths, that is a bug that needs reporting to the Cygwin list. Also, I'm not sure how the developers will react to mishandling a directory named x:, but the behaviour you see is a limitation of the Cygwin platform, not of git.
