Hi,

I'm using curl-7.10.4-pre3 with VC6 compiler on Win2K. I'm having
trouble executing a LIST command as a CUSTOMREQUEST.

Here's what is happening:

1. Establish a connection to a server with a url that looks like:

"user:password_at_myftpserver/"

Here are the server responses:

    "220 myftpserver FTP server (Version wu-2.6.1-18) ready."
    "331 Password required for user."
    "230 User user logged in."
    "257 "/home/mygroup/user_home" is current directory."

Note that the ftp server drops you into a directory other than '/', but
libcurl seems to record that information internally.

2. Execute a CWD commmand as a POSTQUOTE with a path that looks like:

    "../otherdir/"

Here's the response from the server:

    "250 CWD command successful."

3. Execute a PWD command as another POSTQUOTE. The server responds:

    "257 "/home/mygroup/otherdir" is current directory.

4. Execute a CUSTOMREQUEST with the string:

    "LIST /home/mygroup/otherdir/"

and the URL

    "ftp://myftpserver/home/mygroup/otherdir/"

Here are the server responses:

    "250 CWD command successful."
    "550 home/mygroup/otherdir: No such file or directory."

Tracing into ftp.c function ftp_perform() I found this code:

   /* This is a re-used connection. Since we change directory to where the
      transfer is taking place, we must now get back to the original dir
      where we ended up after login: */
   if (conn->bits.reuse && ftp->entrypath) {
     if ((result = ftp_cwd(conn, ftp->entrypath)) != CURLE_OK)
       return result;
   }

   /* change directory first! */
   if(ftp->dir && ftp->dir[0]) {
     if ((result = ftp_cwd(conn, ftp->dir)) != CURLE_OK)
         return result;
   }

The first ftp_cwd() succeeds and the working directory changes to

/home/mygroup/user_home

but the second ftp_cwd() fails. Libcurl appears to drop the first '/'
character of the path passed to ftp_cwd(), so the path seems to be
interpreted as being relative to ftp->entrypath instead of relative to '/'.

Is this a known bug, or is there a way to tell libcurl to retain the
first '/' in the path for the second ftp_cwd?
