Subject: 25.3; server-delete-client:X protocol error using Lucid
Date: Sun, 11 Mar 2018 12:12:30 -0600

Using --with-x-toolkit=lucid results in error:

server-delete-client: X protocol error: BadFont (invalid Font parameter)
on protocol request 46

one of the results is that the command server-edit no longer works as
expected; it does not exit cleanly.  One has to resort to Ctrl+c to get
the terminal back which leaves the server buffer open.

What do you do exactly to get this error?

The problems starts now where, once DONE editing the file, I SHOULD use "server-edit" or "C-x #" to exit/close this buffer and get my terminal "back".
AT THAT POINT, emacsclient SEEMS to close but in reality does not exit cleanly, i.e. the frame is destroyed, etc., I get back to terminal but it is still waiting for emacsclient to terminate and release terminal.  Also, the buffer is still open, it does not get killed.
I have to use Ctrl+c to get my terminal back; THEN open emacsclient again, look for the buffer for xyz.txt (which is still open) and kill it with "C-x k"

Using emacs compiled with gtk3, I do not run into any of that.  ONLY with lucid (and i do prefer lucid over gtk3 so this is important.)

Screenshots attached so you can see the state after using "server-edit" with Lucid.

Noam,

My setup is as such:

- emacs server+client
- I start emacs on every boot using a systemd --user unit:

% cat ~/.config/systemd/user/emacs.service
[Unit]
Description=Emacs: the extensible, self-documenting text editor

[Service]
Type=forking
ExecStart=/usr/bin/emacs --daemon
ExecStop=/usr/bin/emacsclient --eval "(kill-emacs)"
Environment=SSH_AUTH_SOCK=%t/keyring/ssh
Restart=always

[Install]
WantedBy=default.target

THEN, let's say I want to work or edit file xyz.txt.  I run:
% ec xyz,txt

ec is a script I use to run emacsclient
% whence ec | xargs cat
#!/bin/sh
exec /usr/bin/env emacsclient -a "" -c "$@"

THEN I edit the file, etc.
All is fine up to this point.

The problem starts now where, once DONE editing the file, I SHOULD use "server-edit" or "C-x #" to exit/close this buffer and get my terminal "back".
AT THAT POINT, emacsclient SEEMS to close but in reality does not exit cleanly, i.e. the frame is destroyed, etc., I get back to terminal but it is still waiting for emacsclient to terminate and release terminal.  Also, the buffer is still open, it does not get killed.

Chould you check if it still occurs with an Emacs 26 pretest?  I think
there were some fixes around terminal deletion that *may* be relevant.

Also, just to rule things things out, check if it happens with

    emacs -Q --eval '(setq server-name "foo")' -f server-start

    emacsclient -s foo xyz.txt

The problem does NOT occur in  pretest 26.0.91-1

This does not start a server on my box

>     emacsclient -s foo xyz.txt

Can't execute this one if no server started with above command.

Nice, that's good news.

It doesn't give any indication, but if you check with M-:
(server-running-p) you should get `t'.
