Summary: Double slashes and root dir

Initial Comment:
Know bug number 6 states:
libcurl ignores empty path parts in FTP URLs, whereas RFC1738 states that such parts should be sent to the server as 'CWD ' (without an argument). The only exception to this rule, is that we knowingly break this if the empty part is first in the path, as then we use the double slashes to indicate that the user wants to reach the root dir (this exception SHALL remain even when this bug is fixed).

I think this means libcurl will ignore double slashes unless it's the first in the path, which will bring us to the root dir. But that's not what is happening. libcurl is always ignoring the double slashes leaving us with no way to list the root directory. (Except .. hacks)

Sorry, but can you tell me what the problem is with this.
ftp://ftp.sunet.se// gets the root dir for you.

> Using ftp://ftp.sunet.se/%2F works well.

Actually, that does NOT work well I would say as that will make curl issue
"RETR /" which is plain wrong.

But ok, please confirm the following: I guess the problem here is you want
to list the root dir of an FTP server that doesn't let you in in the root
dir as default and you say this doesn't work? If it is, do you know of a
public server that you can repeat the problem with with a complete command
line?

(I guess you've said this all along but I haven't understood it)

This indeed works. But if you try just ftp://ftp.sunet.se// you won't be
changed to the root dir. ftp.sunet.se doesn't have a default home dir, but
you can see that there is no CWD / command given. Using
ftp://ftp.sunet.se/%2F works well.

I tried with curl-7.16.2.

I can't repeat (or possibly understand) your problem:

I take it you use 7.16.2 or a recent CVS?

I tried with both doing this:

$ curl ftp://ftp.sunet.se//lib/ -v

And both versions jump to the directory "/lib" that is based on the root
dir of the server, not the home dir where it logs in.

I also tried the more official way of doing it, by specifying %2f instead
of the double slash, it it too worked with both these versions:

$ curl ftp://ftp.sunet.se/%2flib/ -v
