bug#17352: .emacs.desktop has become unportable between GUI and TTY.

bug#17352: .emacs.desktop has become unportable between GUI and TTY.

[Alan Mackenzie]

Hello, Emacs.

I just tried starting a GUI Emacs, and it refused to process my
.emacs.desktop, complaining:

    "Error (frameset): Font `tty' is not defined [7 times]
    Waraning (frameset): Attempt to delete the sole visible or iconified frame

Emacs deleted my .emacs.desktop before I could look at it (see bug
#17351).  But at a guess, it had recorded the "font" used as "tty" at
the close of my last TTY session, and not finding this "font" in the GUI
font subsystem gave up.

I immediately started a TTY Emacs, and there got some error message
something like "Can't open terminal (0.0)".  For some reason, this error
message wasn't recorded in *Messages*.

This lack of portability is a bug.  Sharing a desktop file between GUI
and TTY sessions is the sort of thing Emacs should be able to do without
batting an eylid.  The font in use and the particular terminal (?) used
to create .emacs.desktop are _not_ essential information.  Such
information should be regarded by the desktop subsystem as hints,
nothing more.

My Emacs is the trunk at revision #116992.

At least in theory, saving&restoring the frameset already takes care
of this. If it is failing, that's a bug.

If you have a repeatable way to trigger this problem, please report it
here so wen can work together to fix it.

With a throwaway userid, in a Linux tty (virtual terminal), start Emacs
and create a ~/.emacs containing the single line

    (desktop-save-mode 1)

Evaluate this form with C-x C-e.

With .emacs in the current window, visit a new file in a new frame with
C-x 5 C-f asdf <RET>, put some random text into the new buffer and save
it with C-x C-s.  Exit Emacs with C-x C-c.

With the same userid, in X Windows, open a terminal and start Emacs (with
no command line arguments).  This produces the aforementioned error
messages:

    Error (frameset): Font `tty' is not defined [2 times]
    Warning (frameset): Attempt to delete the sole visible or iconified frame

.  Only one frame is currently open.

Now close this Emacs session with C-x C-c, and attempt to start another
session on the tty.  In the *scratch* buffer (apparently) appear the
following error messages:

    (emacs:3488): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
    Unable to autolaunch a dbus-daemon without a $DISPLAY for X11

, the pair being repeated 9 times (for a total of twenty messages).  Each
one started directly below where the previous one ended (as though a Unix
file was being displayed on a device expecting MS-DOS line terminators).
This Emacs is unusable, some control characters not being interpreted.
For example, on typing M-x, "^[x" gets displayed in the minibuffer
region, and the minibuffer is not active.  C-x C-c works, however.

After this, please tell me the value of desktop-saved-frameset in the
.emacs.desktop file.

I don't understand why should this happen. Could you also please try
your recipe, but in the fist step, put this in your .emacs

   (setq desktop-restore-frames nil)
   (desktop-save-mode 1)

instead, to make sure that all problems do indeed depend on frameset
restoration.

Thanks,

With that setting, the problems do indeed disappear.  So it would appear
the frameset(s?) is/are the problem.

bug#17352: .emacs.desktop has become unportable between GUI and TTY.

[Juanma Barranquero]

Sorry for the delay, I got the flu and I'm feeling a bit off.

I can reproduce at least part of the problem in my Windows setup. so
it'll be (hopefully) easier to fix.

Meanwhile, a question. What is frame parameter acm-no?

Just a little utility of mine where I've bound the keys F1 - F11 to
select a frame.  F1 selects frame with property (acm-no . 0), F2 .....,
F11 selects frame with property (acm-no . 10).  The property gets set in
an after-make-frame-functions function.  It's a solution to the lack of
decent frame-switching functions for Emacs without mice.  If you're
interested I could send you the code - it's not very long.

bug#17352: workaround

[Edmund Christian Herenz]

Hello,

I can also reproduce above behaviour. I ran into this bug, since I
use both TTY and windowed emacs - sometimes in one session.

>    (setq desktop-restore-frames nil)
>    (desktop-save-mode 1)

This indeed fixes the warning.

I upgraded from Emacs 22.2 to 24.4 recently - and since then I am
affected by this bug.

Best,
CH.

Hi all,

I see this issue even on the latest build of emacs master as of today
(version 26.x).

I ended up on this debbugs via here:
https://github.com/purcell/emacs.d/issues/259

I happened to start emacs with -nw option. My config saves the desktop when
quitting emacs. Then when I opened emacs GUI, I saw this *Warning* buffer:

Error (frameset): font `tty' is not defined.

Juanma, any progress with this issue?

I think I fixed this now on the emacs-26 branch, please test.

Thank you!

I confirm this fix.

How I tested:

1. Open emacsclient -nw&
2. Quit (my config saves desktop when quitting) i.e. kill emacs completely
3. Verify that the desktop file got updated
4. Open emacsclient &
5. Starts up without that "Error (frameset): Font ‘tty’ is not defined"
error

I believe you can mark this as done now.

Thanks, done.
