Barney Gale 1e610fb05f GH-113225: Speed up `pathlib.Path.walk(top_down=False)` (#113693 ) Use `_make_child_entry()` rather than `_make_child_relpath()` to retrieve path objects for directories to visit. This saves the allocation of one path object per directory in user subclasses of `PathBase`, and avoids a second loop. This trick does not apply when walking top-down, because users can affect the walk by modifying dirnames in-place. A side effect of this change is that, in bottom-up mode, subdirectories of each directory are visited in reverse order, and that this order doesn't match that of the names in dirnames. I suspect this is fine as the order is arbitrary anyway.	2024-01-20 03:06:00 +00:00

GH-113225: Speed up `pathlib.Path.walk(top_down=False)` (#113693 )

Use `_make_child_entry()` rather than `_make_child_relpath()` to retrieve
path objects for directories to visit. This saves the allocation of one
path object per directory in user subclasses of `PathBase`, and avoids a
second loop.

This trick does not apply when walking top-down, because users can affect
the walk by modifying *dirnames* in-place.

A side effect of this change is that, in bottom-up mode, subdirectories of
each directory are visited in reverse order, and that this order doesn't
match that of the names in *dirnames*. I suspect this is fine as the
order is arbitrary anyway.
