Summary: GetFileAttributesExW accepts unix paths Product: Wine Version: 1.1.17 Platform: Other URL: http://www.python.org/ftp/python/3.0.1/python-3.0.1.msi OS/Version: other Status: UNCONFIRMED Severity: enhancement Priority: P2 Component: kernel32 AssignedTo: wine-bugs@winehq.org ReportedBy: madewokherd@gmail.com
GetFileAttributesExW("/bin/sh") succeeds if /bin is mapped. Some of python's tests use this check to decide whether it's running on a Unix system. It then tries to start a subprocess using /bin/sh and read its output; this does not work because Wine processes cannot read the output of non-Wine processes.
In python's case, this is harmless and only results in a few test failures.
Files should not be accessible to Windows programs by their Unix paths. We wouldn't want them to think /bin/sh is actually useful.

$ wine 'c:\Python30\python' -c 'print(__import__("os").path.exists("/bin/sh"))'
It prints True on Wine if /bin is mapped and False on Windows.

As a quick test, install Python and run
$ wine 'c:\Python30\python' -c 'print(__import__("os").path.exists("/bin/sh"))'
It prints True on Wine if /bin is mapped and False on Windows.
This isn't a good way to
what if the file c:\bin\sh exists on Windows?
mkdir c:\bin echo > c:\bin\sh GetFileAttributesA("/bin/sh"); returns FILE_ATTRIBUTE_ARCHIVE (0x20)
Unix style paths on Windows refer to the current drive.

These tests are broken then.
The only valid part of this bug report is that Z: is searched when a unix style path is used, but it shouldn't be unless it's the current drive. There's already another bug report open about this.
