Since one may have more than one filesystem side-by-side, this can't be just be a system-wide boolean somewhere. One would have to query the target directory for this information. I am not aware of the existence of code that does such a query, though. Or you can just be practical and test for it. Create a file "foobar" and see if you can open "FOOBAR" in read mode... Agreed. That is how Bazaar's test suite detects this, and it works well. -Andrew.

Actually, I believe we do:

open('format', 'wb').close() try: os.lstat('FoRmAt') except IOError, e: if e.errno == errno.ENOENT: ...

I don't know that it really matters, just wanted to indicate we use 'lstat' rather than 'open()' to check. I could be wrong about the test suite, but I know that is what we do for 'live' files. (We always create a format file, so we know it is there to 'stat' it via a different name.)
