87519 - FTP does not handle default directories correctly

Status: VERIFIED INVALID

(Core Graveyard :: Networking: FTP, defect)

Description

[Joe Pranevich]

According to the latest working draft of the FTP URI specification (that I could
find. http://www.ics.uci.edu/pub/ietf/uri/draft-casey-url-ftp-00.txt), Mozilla
and all previous versions of Netscape handle FTP URIs incorrectly in the case
that the server has a default path.

For example:

Go to ftp://ftp.redhat.com/

According to the spec, you shoul get a directory with "contrib", "redhat", and
"up2date" This is because RedHat's FTP server sets the CWD to /pub when you log
in to the anonymous account. Instead, you currently see "bin", "etc", "lib", and
"pub" (as of 6/24/01)

To see the directory that you currently get as a default, the draft specifies a
URL of:

http://ftp.redhat.com/%2F/

Accd. to section 2.5:

Each of the <cwd> elements in the <url-path> is supplied,
sequentially, as the argument to a CWD (change working directory)
command.

...

 For example, the URL <URL:ftp://[e-mail]/%2Fetc/motd> is
   interpreted by FTP-ing to "host.dom", logging in as "myname"
   (prompting for a password if it is asked for), and then executing
   "CWD /etc" and then "RETR motd". This has a different meaning from
   <URL:ftp://[e-mail]/etc/motd> which would "CWD etc" and then
   "RETR motd"; the initial "CWD" might be executed relative to the
   default directory for "myname". On the other hand,
   <URL:ftp://[e-mail]//etc/motd>, would "CWD " with a null
   argument, then "CWD etc", and then "RETR motd".

So, what Mozilla is doing is essentially a "CWD /" when it shouldn't issue a CWD
at all. This is a general case, even when subdirectories are involved. Mozilla
will always CWD a path from the root, even when there is a default directory
specified by the webserver.

This bug is not the same as bug 84242, although I suspect that they might be
based on similar assumptions in the FTP layer.

As a side note, MS Internet Explorer 5.5's FTP thing appears to handle these
URIs correctly, although previous versions do not.

what is milestone "mozilla1.0" anyway?  Moving to future.

4.x and IE both show  "bin", "etc", "lib", and "pub" when you go to ftp.redhat.com.

Marking invalid.  

if this problem still exists, please provide a valid testcase.
