Subject: [babel] Multiple results blocks for the same source code
Date: Fri, 23 Sep 2011 14:11:02 +0200	[thread overview]
Message-ID: <8062kjxxux.fsf@somewhere.org> (raw)

#+TITLE:     Multiple results blocks for the same source code
#+AUTHOR:    Seb Vauban
#+DATE:      2011-09-23
#+LANGUAGE:  en

* Bug

When evaluating multiple times the following code, we get multiple =results=
blocks.

#+begin_src sh
echo Hello
#+end_src

#+results:
: Hello

#+results:
: Hello

* ERT Test Case

#+begin_src emacs-lisp
(ert-deftest test-org-babel/just-one-results-block ()
  "Test that evaluating two times the same code block does not result in a
duplicate results block."
  (org-test-with-temp-text "#+begin_src sh\necho Hello\n#+end_src\n"
    (org-babel-execute-src-block)
    (org-babel-execute-src-block) ;; second code block execution
    ;; where is point (supposed to be)?
    (goto-char (point-min))
    (should (search-forward "Hello")) ;; the string inside the source code block
    (should (search-forward "Hello")) ;; the same string in the (first?) results block
    (should-error (search-forward "Hello"))))
#+end_src

* Extra context

This problem appeared after having executed sh code blocks (calling Ledger)
which failed -- for some reason still to be studied.

After an Emacs restart, I can't reproduce this anymore. So, not really fixed,
but not there systematically either...

Status is unreproducible right now, but I guess the above test case can
already be added. Please comment on it, for me to progress...

Best regards,
  Seb
