Description Judge Dredd 2021-06-07 02:15:35 UTC

emacs-daemon fails to set the socket location emacsclient 27 expects by default

Reproducible: Always

Steps to Reproduce:
1. switch to emacs 27
2. start emacs-daemon (tested for non-root user)
3. try to run emacsclient
Actual Results:  
error connecting to socket

Expected Results:  
normal start

The problem seems to be in the startup process. Now, as of version 27, emacs
expects XDG_RUNTIME_DIR to be set to use that location for the socket file
(https://github.com/emacs-mirror/emacs/blob/emacs-27/etc/NEWS#L328)
but it's not set correctly when using start-stop-daemon --user for a regular user.

See upstream bug: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=33847

As a workaround, define the EMACS_SOCKET_NAME environment variable (it should typically have a value "/tmp/emacs${UID}/server").

Apparently fixed upstream as of 28.1 (I can't read debbugs properly...)

Not fixed, but I agreed in https://debbugs.gnu.org/51327 (messages #69 and #78 there) that the Emacs 27 behaviour is still better than what was suggested in that bug.
