Due to an user error on my part I was not using os.readlink correctly.
Since links can be relative to their location I think it would make sense
to provide an os.path.resolve helper that automatically returns the
absolute path:
def resolve(filename):
try:
target = os.readlink(filename)
except OSError as e:
if e.errno == errno.EINVAL:
return abspath(filename)
raise
return normpath(join(dirname(filename), target))
The above implementation also does not fail if an entity exists but is not
a link and just returns the absolute path of the given filename in that
case.

Armin
