mod_http_oauth2: Reject URLs with 'userinfo' part (thanks mimi89999) The LuaSocket parser supports these but they're deprecated without replacement by RFC 3986 > Use of the format "user:password" in the userinfo field is deprecated Allowing it in OAuth2 URLs is probably bad from a security perspective.

This module writes out a traceback to `traceback.txt` in Prosodys data
directory (see `prosodyctl about`) when the signal `SIGUSR1` is
received. This is useful when debugging seemingly frozen instances in
case it is stuck in Lua code.
