[issue6975] symlinks incorrectly resolved on POSIX platforms

[Antoine Pitrou]

Antoine Pitrou added the comment:

I don't really understand your algorithm. Why do you need a stack? It should be simply iterative:
- if the symlink is relative, prepend the symlink target to the rest
- if the symlink is absolute, discard the current path and prepend the symlink target to the rest

Here is how pathlib does it:
