Subject: bug#68799: 30.0.50; emacs --fg-daemon fails silently if server-start fails
Date: Mon, 29 Jan 2024 11:54:21 -0500	[thread overview]
Message-ID: <iersf2gjd1e.fsf@igm-qws-u22796a.mail-host-address-is-not-set> (raw)


1. emacs -Q --fg-daemon=/nonexistent/dir/sock
2. Emacs prints "Starting Emacs daemon." and sits in foreground.
3. emacsclient -c -s /nonexistent/dir/sock
4. emacsclient prints and exits:
emacsclient: can't find socket; have you started the server?
emacsclient: To start the server in Emacs, type "M-x server-start".
emacsclient: error accessing socket "/nonexistent/dir/sock"

This is because in step 1, the server actually failed to start, but
Emacs did not log that at all.  In fact, it's impossible to access the
Emacs started in 1 now, since it's not actually running a server and it
has no frames.

The same thing happens with --bg-daemon, although it's slightly more
obvious that something is wrong in that case, because --bg-daemon is not
supposed to sit in foreground.

Emacs with --fg-daemon should instead print an error and exit if it
fails to start the server.
