[issue13229] Improve tools for iterating over filesystem directories

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Oh, forgot to mention, the term "symlink loop" itself is ambiguous.

There are direct symlink loops: an example is a "some_dir/linky" link pointing to "../some_dir/linky". These will fail when resolving them.

There are indirect symlink loops: "some_dir/linky" pointing to "../some_dir". Resolving them works fine, but recursively walking them produces an infinite recursion.

Lots of fun :)
