bug#9315: 23.3; Can't visit VMS file from Windows Emacs 23.3.1

[Alan.Grunwald]

[Resent from mail client bcause I got some kind of error when typing
C-c C-c from the emacs send buffer. Almost certainly configuration problem
at this end rather than anything wrong with emacs 23.3.1. Apologies if
this is a duplicate]

I'm running emacs 23.3.1 (i386-mingw0nt5.1.2600) of 20011-03-10 on
3249CTO

If I type C-x C-f /grunwald@machin:login.com to edit my login.com on a
remote VMS system called machin, emacs prompts for my password and then
fails to open login.com.

Buffer *ftp grunwald@machin* contains

I know next-to no emacs LISP, but I am an experienced programmer and
I've had a go at debugging this by sprinkling (message ... ...) calls
around the code. As far as I can make out, something outside amg-ftp is
calling ange-ftp-send-cmd with the command "dir /$DISK1!/". I believe it
is that that is casuing the problem, but I can't work out why this
command is being attempted.

For what it's worth, if I connect to machin from a DOS box and type PWD,
the response is

    "$DISK1:[GRUNWALD]" is current directory.

It seems to me that the exclamation mark between DISK1 and the slash is
causing the problem, but I've no idea where it's coming from.

I'd really like to use Emacs to edit the files as the strain of using
the VMS editor for some things, MS-Word (cough) for some things and Emacs
for others is beginning to make my head hurt.

Thanks,
Alan

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the bug-gnu-emacs@gnu.org mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':



If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:

I have no access to a VAX any longer (for 15 years or so), and from
reading the sources in ange-ftp.el I cannot find the problem.

Could you, please, apply the following:

(require 'ange-ftp)
(require 'trace)
(dolist (elt (all-completions "ange-ftp-" obarray 'functionp))
  (trace-function-background (intern elt)))

Then rerun your test and show the contents of the buffers

  *ftp ...*
  *trace-output*

Check the buffers, that they do not contain sensitive information like
your password, before sending.

Finally, this has been solved in Emacs 24.1. Thanks for your continuous
testing all the proposed patches!

Note, that `ange-ftp-binary-file-name-regexp' is the empty string in
Emacs 24. For proper editing of text files on a remote VMS machine, this
variable must be changed to match binary files.
