If os.walk were rewritten, it should be as an iterator (generator).
Directory entry and exit functions could still be added as params.
It *is* an iterator/generator. However, I suspect you mean that
it should slurp the dirs/files iteratively instead of using
listdir() as was discussed on c.l.p a few months back.
Yes, I was thinking of that thread.
Thanks for mentioning this thread. Very interesting stuff. Apropos
the implementability of an iterative listdir, I wonder if some
variation of glob.iglob() would fit the bill. (Maybe it's too
slow, though.)
I suspect if I thought about it much longer, only one would
really be needed, the other accommodated by the "topdown" parameter.
Yeah, I think one only needs a post hook. The fact that it's a
generator obviates need for a pre hook, since the yield returns
control to the calling function right around where the pre-hook
would run anyway. For the same reason, the post hook is needed
only for the case topdown=True.
Once you have determined and tested the minimal needed change for
greater functionality, you could either
a) post a suggestion and the revised os.walk to python-ideas
b) submit a feature request to the tracker and attach the revised
function and, if possible, a diff patch
c) both.
I have no idea of the response.
