Hi,

we have some python scripts that are run from Visual Studio, and one of  
them fails because of a wrong git return code when calling 'git describe  
--dirty'

Here's the issue:

=============
import subprocess

GIT_EXE = "<path to git exe>"
GIT_SRC = "<path to git repo>"


# call 'git describe --dirty':
run_git = subprocess.Popen([GIT_EXE, "describe", "--dirty"],
                            cwd=GIT_SRC,
                            stdout=subprocess.PIPE,
                            stderr=subprocess.PIPE)
(output, output_err) = run_git.communicate()
print "Returncode: %s" % run_git.returncode
print "Output:     %s" % output.strip()
=============

Run from wingw, the return code is 0.
Run from cmd, the return code is 1.

Why?

Thanks,
Manuela

Supposedly, when you run Git from cmd.exe, the git.cmd top-level script
(which wraps the git.exe binary) gets executed, and it's currently
affected by this bug [1] (fixed).  When you run Git from Git bash, the
git.exe binary runs directly and hence the bug is not exposed.
