Gregory P. Smith added the comment:
Here's is an os.scandir(path='.') implementation that iterates reading the
directory on the fly instead of pre-building a list.
os.listdir's implementation should ultimately be replaced by this as:
def listdir(path=None):
if path is None:
return list(os.scandir())
return list(os.scandir(path))
Though I have not yet done that in this patch so that I could compare behavior
of old vs new.
Why the scandir name? Read the libc scandir man page. It fits.
I have tested this on POSIX (Linux). I don't have any ability to build Windows
code so I expect that still has bugs and possibly compilation issues. Please
leave comments on the 'review' link.
