Enter your bug report in this message, including as much detail as you
possibly can about the problem, what you did to cause it and what the
local and remote machines are.
If you can give a simple set of instructions to make this bug happen
reliably, please include those. Thank you for helping kill bugs in
TRAMP.
Another useful thing to do is to put (setq tramp-debug-buffer t) in
the ~/.emacs file and to repeat the bug. Then, include the contents
of the *tramp/foo* buffer and the *debug tramp/foo* buffer in your bug
report.
--bug report follows this line--
Using the su method, XEmacs can't kill the shell subprocess, which
prevents it from exiting. To reproduce:
xemacs --no-init-file --no-site-file
C-x C-f /[su/address@hidden/etc/passwd
C-x C-c
The XEmacs window disappears, but the process is still around,
although it thinks it has crashed.
It reports the following on the console:
Fatal error (11).
[ snip message about core dumps. ]
But it hangs, not returning control to the shell.
The process is still around, as reported by ps:
1296 pts/2 S 0:04 \_ xemacs -no-site-file -no-init-file
1297 pts/3 S 0:00 \_ /bin/sh
I also tried to work around the problem by killing the tramp log
buffer, hoping that that would get rid of the subprocess:
C-x k *tramp/su address@hidden
issues the message:
kill (1347, 1) failed: Operation not permitted
Clearly the problem is that the subprocess belongs to root, and not to
me, so the normal XEmacs signalling can't deal with it. I guess that
the way to deal with this would be to somehow hook into the killing of
the buffer (unless this exists, and it's just not working for me). I
am happy to help test any solutions to this problem.
Thanks for your effort in creating TRAMP.
