Prior to this commit, it was impossible to use a module like dnf with a
URL that contains a username with an @ such as an email address
username, because:
dnf:
name: https://foo@example.com:bar@example.com/some.rpm
Would cause netloc parsing to fail. However, the following:
dnf:
name: https://foo%40example.com:bar@example.com/some.rpm
Would also fail because ansible would *not* URL-decode the credentials,
causing the following to be base64 encoded in the Authorization header:
Zm9vJTQwZXhhbXBsZS5jb206YmFyCg==
Which decodes to:
foo%40example.com:foo
Which is *not* the authorized username, and as such, *won't* pass basic
auth.
With this commit, Ansible's url lib behaves like curl, chromium, wget,
etc, and encodes the above to:
Zm9vQGV4YW1wbGUuY29tOmJhcgo=
Which decodes to:
foo@example.com:bar
Which will actually pass the HTTP Basic Auth, and is the same behaviour
that you will find ie. with:
curl -vvI https://foo%40bar:test@example.com 2>&1 |grep Auth | awk '{ print $4 }'
