Bug report

Bug description:

Two closely-related issues in pathlib.Path.resolve():

First, resolve(strict=True) raises RuntimeError rather than OSError when a symlink loop is encountered. This is done only for backwards compatibility, since #25264 made pathlib call os.path.realpath(). It should raise OSError(ELOOP)

Second, resolve(strict=False) suppresses every kind of OS error except symlink loop errors. Again this is only for backwards compatibility. It should suppress exceptions about symlink loops.

Relevant code:

CPython versions tested on:

3.11, 3.12, CPython main branch

Operating systems tested on:
