bug#1687: Emacs.app -- Warning: desktop file appears to be in use by PID 537.

Using Emacs.app, GNU Emacs 23.0.60.1 (i386-apple-darwin9.5.0, NS
apple-appkit-949.35) of 2008-12-14 on GH-iMAC.local.

If I choose "Quit Emacs" from the "Emacs" menu, the next time I start up
Emacs, I get a warning of the form: Warning: desktop file appears to be in
use by PID 537.  Furthermore, if I then try to send a bug report, Emacs.app
freezes after I enter the above as subject of the bug report.

No problem if instead I had chosen "Exit Emacs" from the "File" menu, or use
C-x C-c.

No problem using "Quit Emacs" in Carbon Emacs: GNU Emacs 22.3.1
(i386-apple-darwin9.5.0, Carbon Version 1.6.0) of 2008-10-27 on
leopard.local. (same machine)

[Relson, David]

Yes, I have the same problem as originally reported.

I have a .emacs file in my ~/ directory, i.e. c:\user.  With the
following line:

    (desktop-read)

The problem occurs.  Without the line, the problem goes away.

The problem occurs when the above line is the _only_ line in .emacs

My original .emacs file uses desktop-read in the following manner:

;; This enables saving the current desktop on shutdown.  
;; The ESC-x desktop-save command must be given once 
;; for this to work in perpetuity. 
(desktop-load-default)
(desktop-read)

I've run the desktop-save command but that didn't solve the problem.
FWIW, desktop-save put its .emacs.desktop in c:/Program
Files/GNU/ntemacs22/bin (which seems reasonable).  I copied the
.emacs.desktop file to c:/user but it didn't help.

Does it also happen if you use

 (desktop-save-mode 1)

instead?

With two lines in .emacs, i.e.

(desktop-load-default)
(desktop-save-mode 1)

The PID warning appears when I open a second copy of emacs.  I used to
be able to open multiple copies of emacs without warnings.

Why do you use `desktop-load-default'? Have you tried just with
`desktop-save-mode'?

Yes. Opening multiple copies was allowed before, but it leads to the
last Emacs to exit clobbering the desktop file of the previous
instances. You can set `desktop-load-locked-desktop' to t and Emacs
won't ask you when loading the desktop (though it will still ask
before overwriting the previous instance's desktop while exiting).

The desktop invocations were part of the standard .emacs file when I
started this job several years ago.  Since they worked, I never paid
attention to them.  Having multiple copies overwrite the previous
desktop when exiting is behavior I don't mind.

I've revised my .emacs file to include:

   (setq desktop-load-locked-desktop t)
   (desktop-save-mode 1)

And things seem fine.

Ciao,

David

It will still ask you when exiting.

If you really don't mind the last Emacs standing to win, you can add
this to your .emacs:

;; slightly tested
(add-hook 'kill-emacs-hook
          (lambda ()
            (when (and desktop-dirname desktop-base-file-name)
              (condition-case nil
                  (delete-file (expand-file-name desktop-base-file-name
                                                 desktop-dirname))
                (error nil)))))
