[babel] sreen : unable to run org-babel-screen-test

[bluedian]

Hi,

When running "org-babel-screen-test", a xterm appear with its prompt, but no
message appear. Emacs hangs and my cpu is à 100%.

When hitting c-G (whit debug mode activated), I get this message :
Debugger entered--Lisp error: (quit)
  (not (file-readable-p tmpfile))
  (while (not (file-readable-p tmpfile)) (format "org-babel-screen: File not
readable yet."))
  (let* ((session "org-babel-testing") (random-string ...) (tmpfile
"/tmp/org-babel-screen.test") (body ...) process tmp-string)
(org-babel-execute:screen body org-babel-default-header-args:screen) (while (not
...) (format "org-babel-screen: File not readable yet.")) (setq tmp-string
(with-temp-buffer ... ...)) (delete-file tmpfile) (message (concat
"org-babel-screen: Setup " ...)))
  org-babel-screen-test()
  call-interactively(org-babel-screen-test)
  (unwind-protect (call-interactively chosen) (smex-rank chosen)
(smex-show-key-advice chosen))
  (let ((chosen ...)) (unwind-protect (call-interactively chosen) (smex-rank
chosen) (smex-show-key-advice chosen)))
  smex()
  call-interactively(smex nil nil)

In the * message * buffer, I get this :
Sending source code block to interactive terminal session...
Warning: Tried to connect to session manager, None of the authentication
protocols specified are supported
Entering debugger...

the last sentence "None of the authentication protocols specified are supported"
is surely the key, but I didn't understand it as I have xterm, sh and screen
installed and correctly configurated.

I'm on Ubuntu 9.04 - Jaunty Jackalope, Emacs 23, the last (this morning)
org-mode version on the git repository (I use org-track-update).

Other parts of babel are correctly working (shell and emacs mode without the
screen part)

I just tried it myself, and apparently it's broken with the current git.

I will have a look and report back with my findings!

I was relying on a variable which used to contain the value it needed,
but doesn't do any more. It was a foolish shortcut and now it uses the
official route by processing the parameters that are passed to it.

As I don't have access to the official org-mode git repo, can someone
please apply this patch for me?

br,
benny

P.S. I'm not committing this patch to the org-babel repo, out of fear of
merge issues later on. I guess this route is better? Thanks!

Hi Benny,

We should have caught this usage when we changed the variable passing
behavior in org-babel.  Thanks for the patch, it is now applied.

Hi,

With the last git version (updated by org-track 5 five minutes ago), I have
still the same problem and the same error message.

I'm a bit at a loss with debugging this thing non-interactively. (Yeah I
know, after the first one was unsuccessful that's early to give up.)

But because it uses both the filesystem and GNU screen the error could
lie anywhere and not just in the emacs lisp code.

I will try and see if I can improve the test code by testing checking at
several stages if something has gone wrong, so that I will get a better
idea why and when things start to go awry.

br,
benny

P.S. Could anyone that comes by this with GNU/Linux and GNU screen try
it out as well? I'm using this line to test the setup:
% emacs --batch -l orgloadpath_org-babel-screen-test.el
