Just want to mention that foo@bar is not defined for the HTTP scheme,
but only for the FTP scheme, AFAIK. At least, last time I studied the
RFCs. I do not mean to deny using this notation - just that this use
is not covered by the standards for what I know.
Bye,
Benjamin.

Oops, looks like you're right. I retract my comment.

That is a completely different issue. http://host/path@REV is allowed
by the standard. In the path, almost everything is allowed. Subversion
just has a special interpretation of the path. This was always up to
the server to decide and it is just an (unfortunate?) convention that
the path is often mapped directly to the filesystem (but there are
also many systems which already have other interpretations).

I agree. If it's been decided that user/password specification is not
supported, the parser should complain.

No comment. As I said, I just wanted to make the fact known.

It's not as if Subversion doesn't already support a superset with support for
http://host/path@REV syntax (as good or bad as that syntax might be).
In any case, it's definitely wrong to successfully parse the user@host URL and
then completely ignore the "user@". Right now, if you specify such a URL,
Subversion will not give an error and will just proceed as if you had not
specified the user at all.
Either it's valid syntax, or it's not. It should be supported, or else there
should be an error saying the URL is not valid RFC 1738 (or at least a
warning).

So would I :)

The "//user:password@host:port/path" notation is defined as "Common
Internet Scheme Syntax" in secion 3.1 of RFC 1738. This section does not
specify that the "http" URL schema follows this syntax, merely:
> The scheme specific
> data start with a double slash "//" to indicate that it complies with

Secion 3.3 "HTTP" says that the syntax for the http schema is
http://<host>:<port>/<path>?<searchpart>
and further states:
> No user name or password is allowed.
D'oh!
So if you are a "producer" of http URLs, you would be breaking RFC 1738
if you put the "username:password@" in a http URL. But I suppose you
could be more lenient as a "parser" of URLs. Allowing a super-set of the
http schema defined by RFC 1738 may still mean you are a valid 1738
parser...
In any case, I definitely find the "username:password@" syntax useful!
