[py-dev] patch to allow usage of py.lib within non-administrator account on windows

[Harald Armin Massa]

Hello!

atm. py.lib uses

os.tmpfile()

within fdcapture.py.


On windows os.tmpfile() tries to create the file within the root of
c:\; and it is quite good practice to disallow write access to this
directory for non-admin users (as this avoids killing crucial system
files)

So installation on windows using an user without write-access to c:\,
even setup.py fails with "permission.denied"

More info in:

http://groups.google.com/group/comp.lang.python/browse_thread/thread/4aa54e927f11bbc3?tvc=2


It is fixable by using:

def maketmpfile(self):
        """ create a temporary file
        """
        #~ f = os.tmpfile()
        f=tempfile.TemporaryFile()
        newf = py.io.dupfile(f)
        f.close()
        return newf

    def writeorg(self, str):
        """ write a string to the original file descriptor
        """
        tempfp = tempfile.TemporaryFile()
        try:
            os.dup2(self._savefd, tempfp.fileno())
            tempfp.write(str)
        finally:
            tempfp.close()

within lines 42ff of py/io/fdcapture.py, of course after importing tempfile.

I submit this patch into public domain.

Harald
