all org-buffers modified

all org-buffers modified

[Joost Helberg]

Hi,

upon startup of emacs (and load of desktop), all my freshly opened
org-buffers end up being modified. There's no undo information
available and debugging the org-mode function doesn't give me any clue
as (buffer-modified-p) returns false the whole time.

Once in a while (twice a month) I have to stop and start emacs and the
nuisance of answering `y' to all questions about modified buffers.

In my .emacs org-mode is treated very much the same way as txt or tex
buffers, but these don't end up being modified right after initial
load. Also org-startup-align-all-tables and
org-insert-mode-line-in-empty-file are set to off.

Has anyone any clue where to look for a solution as I obviously like
freshly loaded buffers to be not modified.

regards,

Joost

That shouldn't happen (and it does *not* happen in my case): the files are
opened but the buffers are *not* modified. But I'm confused about what
you are saying: (buffer-modified-p) returns nil the whole time, so that meant
they are unmodified. When do they become modified?

That's what I see in any case, so it must be an artifact of your setup.
Have you tried starting with emacs -q and a minimal org init file?
If that works, then bisecting your way through your .emacs seems like
the next step. In particular, starting without loading desktop seems
like a worthwhile experiment.

Nick,

I did that, but didn't quite get to covering all customizations. It
now turns out that the following makes the symptoms happen:

(add-hook 'org-mode-hook
                    (lambda () (set-buffer-file-coding-system 'utf-8)))

The documentation of set-buffer-file-coding-system clearly states
that it leaves the buffer modified _on purpose_. A third parameter
controls this behaviour.

Hence, my .emacs should contain:

(add-hook 'org-mode-hook
                    (lambda () (set-buffer-file-coding-system 'utf-8 nil t)))

Solved.

regards,

Joost
