The small first commit reintroduces
sanitize_server_name
in the public API. In Fractal, we use it to validate the string in the input before allowing the user to trigger the discovery.The main commit changes a bit the discovery process: before, server names like
example.org
would only be checked for the presence of a well-known, and only URLs likehttps://example.org
would be checked as a homeserver. Now, providingexample.org
will also check ifhttps://example.org
is the URL of a homeserver.Sadly I don't think it's possible to add tests for it as it would require to have a homeserver accessible via HTTPS.
