tramp does not work when using athena

tramp does not work when using athena

[Ralf Schmitt]

I'm using emacs trunk on a 64 bit archlinux box, and noticed that tramp
does not work when configuring emacs to use the athena toolkit.
The following does not work:

,----
| ./configure --with-x-toolkit=athena --with-xft
| make
| src/emacs -Q --load ~/doit.el 
`----

where doit.el contains:
,----[ doit.el ]
| (require 'tramp)
| (setq tramp-verbose 5)
| (setq tramp-default-method "ssh")
| (find-file "/root@mail:/etc/aliases")
`----

The emacs modelines says "Opening connection for root@mail using ssh..."
and it hangs there. C-g does work however.

If I change the configure line to any of the following two, it works:

./configure --with-x-toolkit=gtk3 --with-xft
./configure --with-x-toolkit=athena --with-xft --without-gconf --without-rsvg

Cheers,
Ralf

Could you, please, increase tramp-verbose to 6 in your doit.el, and
rerun the test? Tramp's debug buffer shall tell us what's happening.

Best regards, Michael.

I noticed that sometimes tramp works fine even when using athena.

That's the contents of the debug buffer when it fails:

,----

| 22:22:06.705848 tramp-wait-for-regexp (3) # Opening connection for root@mail using ssh...done
`----

Is it waiting for a prompt from the local shell here?

Yes. If you would set tramp-verbose to 6, we could see more details.

Sorry, about that. Here's the debug buffer at level 10:

Likely not. Ralf has performed more tests (communicated off the list);
the problem is the (missing) tty.

We are working on a solution.

Hi Michael,

are there any news on that front? I'm afraid I'm struggling with the
same problem on GNU/Linux with a Lucid-build. While using 'sshx' works
in principal, it fails to use a shared ssh connection, which is pretty
important for me when using Tramp in eshell, otherwise it's just too
slow. (Emacs/GTK works fine, though.)

I can give you some more details on the problem itself. tramp uses
start-process to execute a shell and wait for the initial prompt. But
the shell doesn't output one, since stdin is not connected to a tty (It
should be). I used the following short program:

,----[ isatty.c ]
| #include <stdio.h>
| #include <unistd.h>
| 
| int main(int argc, char **argv)
| {
|     fprintf(stdout, isatty(1) ? "yes\n" : "no\n");
|     return 0;
| }
`----

Running the following command

,----
| [py27] [git:master+] ~/vendor/emacs/ % src/emacs -Q --execute '(progn (start-process "test" "test" "/home/ralf/isatty")(switch-to-buffer "test"))'
| 
| (process:18919): GLib-WARNING **: In call to g_spawn_sync(), exit status of a child process was requested but SIGCHLD action was set to SIG_IGN and ECHILD was received by waitpid(), so exit status can't be returned. This is a bug in the program calling g_spawn_sync(); either don't request the exit status, or don't set the SIGCHLD action.
| Warning: Cannot convert string "Inconsolata-11" to type FontStruct
`----

gives me a buffer with the string "no". The above warning message looks
like another problem.

I worked around the issue by configuring with

Looks to me like you need a combination of scpc and sshx. Hmm, that's a
problem, Tramp does not support to combine methods.

What about creating your own method? Something like this in your .emacs:

(add-to-list 'tramp-methods
  '("myssh"
    (tramp-login-program        "ssh")
    (tramp-login-args           (("-l" "%u") ("-p" "%p")
				 ("-o" "ControlPath=%t.%%r@%%h:%%p")
				 ("-o" "ControlMaster=yes")
				 ("-e" "none") ("-t" "-t")
				 ("%h") ("/bin/sh")))
    (tramp-async-args           (("-q")))
    (tramp-remote-sh            "/bin/sh")
    (tramp-default-port         22)))

Thanks Michael, this special 'myssh' method works.

I can also confirm that Ralf's suggestion to use Lucid in combination
with '--without-gconf' does also work with the normal 'ssh' method. This
is what I'm using now since I don't care for gconf anyway. Thanks Ralf!

It is just a bit strange that it depends on the toolkit and/or gconf
whether ssh can allocate a pseudo terminal or not. The manual says that
this is a common problem with older ssh and cygwin, but I see the exact
same problem with a Lucid&gconf build and OpenSSH 5.8p2:

M-x eshell
ssh somehost
"Pseudo-terminal will not be allocated because stdin is not a terminal"

(The login works, but no prompt is appearing.)

Cheers,
David

There is something else going on here.  I can not reproduce this error, I 
always get "yes" in the buffer.  Futhermore, g_spawn_sync is a function in 
glib.  But Emacs never calls it, so where does it come from?  Can you run 
strace on your Emacs to see what it tries to spawn?  Since you leave out gconf 
and rsvg, glib does not get linked in, so the problem dissapears.

You should file a proper bug report so we can see how you configured your 
Emacs.  Also, what system do you run on?

g_spawn_sync is called during normal initialization by init_gconf. here

strace tells me that emacs forks and tries to exec dbus-launch. The
warning message is printed right after dbus-launch finishes. I really
think this is another issue...

I also have the problem Arch linux, albeit 32bit. So far I could *not*
reproduce this on Debian/sid, nor on OS X 10.6/macports.
