bug#4614: 23.1.50; tramp-ftp-file-name-handler: Recursive `require' for feature `ange-ftp'

[Stephen Berman]

Until sometime within the last few weeks (sorry, I can't narrow it down
more), the following (anonymized) code worked fine:

(defun my-ftp ()
  "Call dired on my ftp server."
  (interactive)
  (require 'tramp)
  (let ((default-directory "/ftp:my-name@my.server.net:/"))
    (call-interactively 'dired)))

But now it throws the error in the Subject line (also with emacs -Q
built with make bootstrap).  When I comment out (require 'tramp) and
eval the resulting defun in emacs -Q, then I get this error:

expand-file-name: Recursive load: "/home/steve/cvsroot/emacs/lisp/net/tramp.elc", "/home/steve/cvsroot/emacs/lisp/net/tramp.elc", "/home/steve/cvsroot/emacs/lisp/net/tramp.elc", "/home/steve/cvsroot/emacs/lisp/net/tramp.elc", "/home/steve/cvsroot/emacs/lisp/net/tramp.elc", "/home/steve/cvsroot/emacs/lisp/dired.elc"

Doing `C-x d RET /ftp:my-name@my.server.net:/ RET' works as always.
After doing this, then my-ftp also works (both with the require-sexp and
without it).

The problem is only with ftp handling; the following defun works fine:

(defun sv ()
  "Call dired on /su::/var/log."
  (interactive)
  (require 'tramp)
  (let ((default-directory "/su::/var/log"))
    (call-interactively 'dired)))

Did something change in the ftp handling that I have to adapt my-ftp to,
or is this a bug in Emacs?

Are you sure? It fails for me in the same way in both 22 and 23.1.
(It seems you can require ange-ftp beforehand as a workaround.)

Indeed. I've fixed this in tramp-ftp.el. Stephen, could you please
check, whether it works for you?

Best regards, Michael.

I haven't updated yet to get your change, but I confirm the workaround
works with emacs -Q on my current build.

However, I just tried the code again with my init file on my current
build and I cannot reproduce it now.  After my init file loaded, I did
`C-h v features' and found both ange-ftp and tramp-*, which would
explain why it works.  I don't know why it didn't work when I reported
it (with the same initializations), but that failure happened in several
separate Emacs sessions, on at least two different days.  Perhaps I
loaded some function that unloaded ange-ftp, ...or it's a heisenbug.
Anyway, I'll update and try your fix, Michael.  You can wait till I
confirm it works to close the bug, but that might not be till tomorrow.
But since it appears to be unreproducible, it's probably ok to close it
now.

I just updated and confirmed it makes my code work with emacs -Q (and
also with my initializations).

Thanks for testing. I've close the bug.
