Subject: 23.1.50; tramp su/sudo makes vc-dir hang (found remote shell ...)
Date: Sat, 31 Oct 2009 15:54:32 +0100

To edit system configuration files, I'd like to use tramp's su:: or
sudo::. What blocks me to do that is that I have versioned /etc (with
etckeepr over Git) and I need to commit the performed changes
afterwards.

When not inside su::/sudo:: I often commit stuff in Git repositories
using vc-mode. That unfortunately does not work under tramp's
su::/sudo::. Trying to do that results in vc-dir hanging forever just
after the "found remote shell on ..." message and the correspondent
"waiting" message in the vc buffer if I stop Emacs with C-g.


Many thanks in advance,
Cheers

Looks to me like vc-git is waiting for a password, or something like
this. Could you, please, check the *tramp ...* buffer, whether you see a
corresponding message?

If there is nothing obvious, you might set `tramp-verbose' to 8, and
rerun the test. The corresponding debug buffer of Tramp shall tell us
what happened.

I've checked the *tramp ...* buffer and I found it empty.

> what happened.

... so I've tried this, the *tramp ...* buffer was still empty, but the
*debug tramp ...* was not. I'm attaching its content, gzipped since it
is 160 Kb (yes, I've cleaned it up just before doing the test, but still
... :-).

AFAICT, in that log I see the password being delivered to su (I did the
test with the "/su::" prefix), luckily not reported in the log, and I
also see the prompt of a root shell clearly returned to tramp, so I
don't think the issue is the "waiting for a password". Rather, it looks
like that in the vc <-> tramp dialog someone fails to recognize that the
login has been properly done.

Thanks for your feedback,
Cheers.

The last command Tramp performs is

cd /etc/; exec git ls-files -z -o --directory --no-empty-directory --exclude-standard --

Nothing returned. Could you, please, run the command as root in a shell,
and see what happens? Maybe with and without the "exec" ...

Sure:

  root <at> usha:/etc# git ls-files -z -o --directory --no-empty-directory --exclude-standard --
  root <at> usha:/etc# echo $?
  0
  root <at> usha:/etc# touch a
  root <at> usha:/etc# git ls-files -z -o --directory --no-empty-directory --exclude-standard --
  aroot <at> usha:/etc# echo foo >> inittab 
  root <at> usha:/etc# # note the heading 'a' before the prompt
  root <at> usha:/etc# exec git ls-files -z -o --directory --no-empty-directory --exclude-standard --
  zack <at> usha:~$ echo $?
  0
  zack <at> usha:~$ 

(I'm not sure the last return code is actually faithful, as I haven't
 verified whether su returns to the caller the exit code of the shell
 process.)

Cheers.

No problem. The "-z" option let's return a null byte instead of a
newline. Tramp shall be able to handle it, see bug report #3858.

What I'm curious about is, why your commands are preceeded by
"exec". I've checked Emacs 23.1.50; git commands are executed without
"exec" in Tramp. Maybe you have an outdated vc-git.el in the way?

Could you, please, start "emacs -Q" and see, whether it works better? If
it still doesn't work, set `tramp-verbose' to 10, and show the debug
buffer of Tramp, again.

Best regards, Michael.

The only vc-git.el I've found on my machine is the one shipped with
Emacs 23.1.50 (it's coming from the emacs-snapshot Debian package, the
maintainer is Cc-ed).

> Could you, please, start "emacs -Q" and see, whether it works better?

With "emacs -Q" it works properly.

As my main customization is using viper mode, I've also tried enabling
it just after "emacs -Q" and bingo, it stops working. Looks like the bug
is Viper-related :-(

Cheers.

Here I cannot help, I don't know that code. Just a short scanning shows,
there are a lot of defadvices, for example for `vc-diff'. This might
require more detailed analysis by somebody familar with viper.

Sure, no problem, I'm just retitling the bug report to highlight the
specificity to viper.

Thanks for all your help!

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

Are you still seeing this issue in recent Emacs versions?  If so, can
you post a recipe to reproduce the problem, starting from "emacs -Q"?
