I know I keep flipflopping on this one, but the more I think about it
the more I believe it is better to drop those names than to raise an
exception. Otherwise a "naive" program that happens to use
os.listdir() can be rendered completely useless by a single non-UTF-8
filename. Consider the use of os.listdir() by the glob module. If I am
globbing for *.py, why should the presence of a file named b'\xff'
cause it to fail?
To avoid silent skipping, is it possible to drop 'unreadable' names, issue a
warning (instead of exception), and continue to completion?
"Warning: unreadable filename skipped; see PyWiki/UnreadableFilenames"
That would be annoying as hell in most cases.
OK. Put one warning in the docs at the top of OS/Files and Directories:
Note: On Unix, illegal filenames (and the files they name) are silently
ignored by many of the functions below.
-- but perhaps with more specific info, such as what is illegal, which
functions, and how to fix outside of Python.
I consider the dropping of unreadable names similar to the suppression
of "hidden" files by various operating systems.
That is documented, sometimes annoying, and reversible when it is.
Python should at least document doing something similar.
