I miss ange-ftp ($#@!Tramp)

I miss ange-ftp ($#@!Tramp)

[Clay Jones]

Hello,

I work in a development environment which does not support secure 
copying via any of tramp's protocols.  I also do not have decision 
making power for implementing these protocols.  I have the default 
setting for tramp set to ange-ftp "(setq tramp-default-method "ftp")" 
in my .emacs file, but I routinely receive errors like:

Wrong type argument: number-or-marker-p, nil

when trying to open/save files.  I've spent a lot of time just trying 
to get back to an environment where I can open and save files remotely 
via FTP.  Any suggestions?

Thanks,

clay

Oh, boy, this is bad.  I got similar reports previously but didn't
spend too much time on them because I thought it's not Tramp at
fault.  But let me try to change this.

First of all, getting back to Ange-FTP involves setting
file-name-handler-alist to the right value.  The right line is still
in ange-ftp.el, only commented out.  So you want to remove the Tramp
entries from file-name-handler-alist and put in the Ange-FTP entries
instead.

Secondly, could you produce a backtrace (loading the *.el files
instead of the *.elc files to avoid bytecode)?  Maybe I can see this
time what's going wrong.

I was able to visit and also save a remote file using ange-ftp, but I
had to get out of the debugger first and then find the buried file.

Using today's CVS snapshot, Tue, 2002 Nov 26  11:49 UTC
GNU Emacs 21.3.50.48 (i686-pc-linux-gnu, X toolkit)
started with

     /usr/local/bin/emacs -q --no-site-file --eval '(blink-cursor-mode 0)'

First, I evaluated all the following:

    (progn
      (require 'tramp)
      (setq tramp-verbose 10)
      (setq tramp-debug-buffer t)
      (setq tramp-default-method "smx")
      ;; when running `emacs -q -l ... ' need to set this
      (custom-set-variables '(shell-prompt-pattern "^[^#$%
    ]*[#$%>] *")))

     ;; [need passive mode for ftp with firewall]
    (setq ange-ftp-try-passive-mode t)

    ;; [set ange-ftp-default-user for ange-ftp]
    (custom-set-variables '(ange-ftp-default-user "ftp@gnu.org"))


    ;;; from emacs/lisp/net/ange-ftp.el

    ;;; This regexp takes care of real ange-ftp file names (with a slash
    ;;; and colon).
    ;;; Don't allow the host name to end in a period--some systems use /.:
    ;;;###autoload
    (or (assoc "^/[^/:]*[^/:.]:" file-name-handler-alist)
        (setq file-name-handler-alist
              (cons '("^/[^/:]*[^/:.]:" . ange-ftp-hook-function)
                    file-name-handler-alist)))

    ;;; This regexp recognizes absolute filenames with only one component,
    ;;; for the sake of hostname completion.
    ;;;###autoload
    (or (assoc "^/[^/:]*\\'" file-name-handler-alist)
        (setq file-name-handler-alist
              (cons '("^/[^/:]*\\'" . ange-ftp-completion-hook-function)
                    file-name-handler-alist)))

    ;;; This regexp recognizes absolute filenames with only one component
    ;;; on Windows, for the sake of hostname completion.
    ;;; NB. Do not mark this as autoload, because it is very common to
    ;;; do completions in the root directory of drives on Windows.
    (and (memq system-type '(ms-dos windows-nt))
         (or (assoc "^[a-zA-Z]:/[^/:]*\\'" file-name-handler-alist)
             (setq file-name-handler-alist
                   (cons '("^[a-zA-Z]:/[^/:]*\\'" .
                           ange-ftp-completion-hook-function)
                         file-name-handler-alist))))


Then I visited a file with a command like this (I changed the name of
the user and the destination):

    (find-file "/user@foo.net:~user/public_html/links.html" nil)


This threw me into the debugger:

Re: I miss ange-ftp ($#@!Tramp)

[Robert J. Chassell]

Oops!  My apologies, I forgot to load the the *.el files instead of the
*.elc files to avoid bytecode.  

Here is a new bug report, from a new instance of Emacs, with the *.el
files loaded, and with a copy of the new debugger log and of the new
*ftp emrc@bcn.net* buffer.  The results were the same as before:

More recent versions of Tramp use a different set of methods.
Maybe the error message should have said "method smx unknown" or
something like that.

I think you want the "ssh" method which auto-detects whether
mimencode or uuencode should be used.

Or maybe you want "sshx" which executes "ssh ... -e none -t -t /bin/sh"
instead of "ssh ... -e none".

Does this help/work?

    More recent versions of Tramp use a different set of methods.
    ... 
    Or maybe you want "sshx" which executes "ssh ... -e none -t -t /bin/sh"
    instead of "ssh ... -e none".

I tried sshx and I was able to visit and also (I think) save that
remote file using ange-ftp, but the visited file was in a buried
buffer, in fundamental mode, and ...

  * the *Backtrace* buffer says:

        Debugger entered--Lisp error: (error "Login failed")

    [and more which I list below]

  * the  *ftp user@foo.net*  buffer says:

        ftp> open foo.net
        Connected to foo.net.

    [and more which I list below]

  * the  *tramp/nil user@foo.net* says in toto:

        31223: ssh: connect to address 209.213.0.60 port 22: Connection refused

        Process *tramp/nil user@foo.net* exited abnormally with code 1

Also, I just tried
    (setq tramp-default-method "ssh")
in a new instance of Emacs and it looks like tramp generated the same
problems.  (I won't include those new error messages here, since I
they look similar on a quick glance to the one's here.)

I've seen it once some days ago, and my feeling is that it was related
to Emacs 20.7 and the new MD5 stuff you've introduced
recently. Haven't debugged it (yet), 'cause 20.7 isn't my preferred flavor.

Best regards, Michael.

Re: I miss ange-ftp ($#@!Tramp)

[Richard Stallman]

    in my .emacs file, but I routinely receive errors like:

    Wrong type argument: number-or-marker-p, nil

    when trying to open/save files.

Can you set debug-on-error and make backtraces to show
us some details of these failures?
Please read the Bugs section in the Emacs manual, which provides
guidelines on how to write a bug report to give us the
necessary information so we can fix the bug.

This means that both Tramp and Ange-FTP are present in
file-name-handler-alist, I think.  (Type C-h v
file-name-handler-alist RET to find out.)

That's not good.

Tramp has been changed to automatically invoke Ange-FTP when
necessary.  So I suggest to either use that facility (if it works),
or to disable Tramp completely if you want to just use Ange-FTP
without Tramp.

I think the following code will disable Tramp:

(setq file-name-handler-alist
      (delelete (assq 'tramp-completion-file-name-handler
                      file-name-handler-alist)
                file-name-handler-alist))
(setq file-name-handler-alist
      (delelete (assq 'tramp-file-name-handler
                      file-name-handler-alist)
                file-name-handler-alist))

I think I should go back to the first bug report where it says that
Ange-FTP failed.
