bug#16954: 24.3.50; desktop.el: messages for autosaved files unnoticeable when desktop is restored

[lee]

Dear Developers,

this is more like a feature request than a bug report:

Upon starting emacs and restoring a saved desktop, when there are files
for which autosave versions are being found, the messages in the
minibuffer suggesting that one may want to restore the autosaved version
are being overwritten by other messages fast enough to go unnoticed.

This leads to the non-autosaved versions of such files being loaded, and
by the time one might switch to a buffer visiting a file for which an
autosave version is available, the autosave version is likely to be
disregarded since one isn´t aware that it exists.  (It stays around and
may be outdated once the file is modified.)


I´m not sure what would be best to do about this.  Perhaps when
switching to a buffer visiting a file that has an autosave version,
there could be again a message in the minibuffer, pointing out that the
autosave version could be restored.

It might also be nice to have a function that creates a buffer with a
listing of all loaded files that have an autosave version.  One could
then refer to the listing to clean things up.  Similar to dired
functionality, one functionality for this buffer would be to display a
diff between the loaded version and the autosaved version of the file on
demand.

FWIW:


(defcustom desktop-buffer-auto-save-file-list-name
  "*auto-save-files*"
  "Name of buffer to create a list of files for which auto-save
files exist.  The contents of this buffer are deleted every time
the list is created."
  :type '(string)
  :group 'desktop)


(defun desktop-make-auto-save-list ()
  "Replace, and thereby delete, all contents of buffer specified
through desktop-buffer-auto-save-file-list-name with a list of
files for which auto-save files exist and display the buffer.
When the buffer does not exist, it is created.

desktop-after-read-hook can be set to
'desktop-make-auto-save-list to call this function after
restoring the desktop has successfully completed."
  (interactive)
  (pop-to-buffer desktop-buffer-auto-save-file-list-name)
  (delete-region (point-min) (point-max))
  (dolist (buffer (buffer-list))
    (with-current-buffer buffer
      (let ((filename buffer-auto-save-file-name))
	(if filename
	    (when (file-exists-p filename)
	      (pop-to-buffer desktop-buffer-auto-save-file-list-name)
	      (insert (concat filename "\n"))))))))


(setq desktop-after-read-hook 'desktop-make-auto-save-list)


Feel free to add this, or a modified version, to desktop.el, or to
otherwise use it.

(I'm going through old bug reports that unfortunately got little response at
the time.)

The way Emacs displays messages/prompts has changed a bit over the last
few years -- they overwrite each other less often than before.  Are you
still seeing this issue in more recent versions of Emacs?

If so, do you have a recipe to reproduce it, starting from "emacs -Q"?

More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.

What about this enhancement-request part?

  It might also be nice to have a function that creates
  a buffer with a listing of all loaded files that have
  an autosave version.  One could then refer to the
  listing to clean things up.  Similar to dired
  functionality, one functionality for this buffer would
  be to display a diff between the loaded version and
  the autosaved version of the file on demand.

I'm not sure how generally useful that would be -- but perhaps it would
make sense in a desktop.el context?
