ediff-revision and "Using keyboard-interactive authentication^M" in text

[Lennart Borgman]

When I do

    M-x ediff-revision RET

when viewing help.el in my local copy of the repository I get this in 
the temporary checked out latest version of help.el:

 >>>>>>>
(defun resize-temp-buffer-window ()
  "Resize the current window to fit its contents.
Will not make it higher than `temp-buffer-max-height' nor smaller than
`window-min-height'.  Do nothing if it is the onlyUsing 
keyboard-interactive authentication.^M

 window on its frame, if it
is not as wide as the frame or if some of the window's contents are scrolled
out of view."
<<<<<<<<<<

Where does that "Using keyboard-interactive authentication^M" come from?

I guess there might be something wrong with the cvs tools I am using but 
I do not understand. I do not know where it would be most appropriate to 
ask this question, but the problem seems to occur only within Emacs so I 
start here. (BTW: Can you specify the path the the cvs program somewhere 
in Emacs?)


I am doing this on w32, using CVS Emacs from 2005-11-22. The cvs tools I 
am using is cvsnt which says:

Configure your PuTTY session to subversions to have an explicit login
name (Connection->Data in the PuTTY Configuration dialog) and, if that
doesn't help, try disabling the "Attempt keyboard-interactive auth"
option in the SSH->Auth tab of the Configuration dialog).

Thansk Eli, but there are several things I do not understand here. I did 
a connection once to save the host key. Does puTTY save configuration 
parameters (like those you suggest) every time I connect using puTTY?

The first suggestion unfortunately did not work. In PuTTY the string is 
still output. And if disable "Attempt keyb..." then at least PuTTY can 
not login.

The output of the string "Using keyboard ..." seems seriously out of 
phase with the fetched module. Could the string has been sent to STDERR?

If I from the command line do

    c:\myrep\emacs\lisp> cvs diff isearch.el

then I do not see the string. If I do this in an interactive shell in 
Emacs I do not see it there either.

Perhaps does plink gets confused in the case when ediff-revision is used?

It doesn't save the configuration unless you tell it.  However, if you
invoke PuTTY interactively (i.e., not the command-line plink.exe, but
putty.exe itself), it pops up a session configuration dialog.  There,
you can configure a session for subversions.gnu.org and save it.  That
configuration will henceforth be used by plink.

Maybe, I don't know.  You will have to see how ediff-revision invokes
plink, perhaps it does it in a way that plink thinks it's an
interactive invocation.

Are those settings then used when plink is called from cvs.exe if I 
specify for example

    cvs -z3 -d:ext:anoncvs@subversions.gnu.org:/cvsroot/emacs co emacs

BTW is subversions.gnu.org the same as savannah.gnu.org?

ediff-revison calls "cvs" with some arguments. Maybe it is then 
important how cvs is invoked. What should I look for?

Yes.  plink.exe looks in the PuTTY configuration file for a session
that names the repository machine, and if found, uses its settings.

They are resolved to the same IP address, so I guess they are the
same.

I don't know; for starters, just post here what is the exact command
line used bu ediff-revison to invoke cvs.

Just a guess:  It has something to do with ssh.  In the file ~/.ssh/config,
I have:

Host subversions.gnu.org
     Protocol 2
     ForwardX11 no

The last line prevents messages spilling into Emacs buffers.  Perhaps there's
an equivalent setting for Windows.

I did ask this question a month ago - and I answered it myself. That 
time I thought that the problem did go away after updating cvsnt. 
Obviously it is still there. So this answer is incorrect: 
http://lists.gnu.org/archive/html/emacs-devel/2005-10/msg00823.html

Sorry for starting a new thread.
