I upgraded this morning from an Emacs CVS build from Jan 28 or 19 to
the
pretest release, and noticed a regression or undocumented change with
respect to org-after-todo-statistics-hook. I am using the org-mode
which is included in the pretest distribution.
I have a function based on the code in section 5.5 of the Org manual
to
close projects when their subtasks are complete. Now, if I have a
headline which does not have a subtask counter in it and toggle one of
its children to DONE, my org-after-todo-statistics-hook function gets
called with n-done and n-not-done values of 0. The parent headline
thus
has its TODO status changed.
I don't think it matters too much, as my code worked before, but my
hook
function is `org-summary-todo' from the following. The first case of
the cond is being activated.
(defun mde-org-entry-is-project-p ()
"Query whether the current headline is a project, returning
non-`nil' if it is and `nil' otherwise."
(member "PROJECT" (org-get-tags-at)))
;;; Taken from Org Mode manual chapter 5.5
(defun org-summary-todo (n-done n-not-done)
"Switch entry to DONE when all subentries are done, to TODO
otherwise."
(let ((org-log-done nil)
(org-log-states nil))
(cond
((and (or (org-entry-is-todo-p)
(mde-org-entry-is-project-p))
(= n-not-done 0))
(org-todo
(if (mde-org-entry-is-project-p)
"FINISHED"
"DONE")))
;; Entry is a project that is marked done
((and (mde-org-entry-is-project-p)
(not (org-entry-is-todo-p))
(org-get-todo-state)
(> n-not-done 0))
(org-todo 'none))
;; Entry is a task
((and (not (mde-org-entry-is-project-p))
(not (org-entry-is-todo-p))
(org-get-todo-state)
(> n-not-done 0))
(org-todo (org-get-todo-sequence-head))))))
There is a small chance that the problem was actually introduced a bit
earlier, perhaps since my Jan 20 build, but I think I would have
noticed
it after at least the Jan 28 build.
I have CC'd bug-gnu-emacs to get this in as a bug report there as
well.
