Can't reconnect to the daemon

[danielkrizian]

I have started emacs (v26.1) server:

$ emacs --daemon

I connected using

$ emacsclient -t

From within emacs, well spacemacs, I restarted the daemon SPC q r, which executed dotspacemacs/resume-emacs-resume-layouts tied to restart-emacs.el.

After daemon restarted, I see the process in htop running but can't reconnect to it.

$ htop

  PID USER      PRI  NI  VIRT   RES   SHR S CPU% MEM%   TIME+  Command                                                                                                                                    
 6579 dk         20   0  232M  164M  9664 S  0.0  0.3  0:05.46 /opt/conda/bin/emacs --daemon=server --resume-layouts --restart-emacs-desktop /tmp/restart-emacs-desktopOpor7P
 6578 dk         20   0 77948 11348 10024 S  0.0  0.0  0:00.00 /opt/conda/bin/emacs --daemon=server --resume-layouts --restart-emacs-desktop /tmp/restart-emacs-desktopOpor7P  

I was expecting to see the message Emacs daemon restarted! Use '%s -nw -s %s %s' to reconnect to it pop up in my bash terminal, but it does not appear.

How can I reconnect to the server? I tried this:

$ emacsclient --s server -t
emacsclient: can't find socket; have you started the server?
To start the server in Emacs, type "M-x server-start".
emacsclient: error accessing socket "server"
$ 

Can I use the /tmp/restart-emacs-desktopOpor7P information somehow?

Hi @danielkrizian, this might happen if Emacs is not able to start successfully in the daemon mode, possibly due to some bug in init file, could try running /opt/conda/bin/emacs --daemon=server --resume-layouts --restart-emacs-desktop <desktop file> yourself, this might given some hint as to what went wrong. As to using the information in desktop file, you use the function restart-emacs--restore-frames-using-desktop to load frames from the desktop file, do something like (restart-emacs--restore-frames-using-desktop "<desktop file>")

Hi @iqbalansari, thanks, I tried running as you suggested, still don't get the expected behavior, i.e. don't get the expected message Emacs daemon restarted! Use '%s -nw -s %s %s' to reconnect to it and the terminal does not show the restored emacs buffers from previous session.

Step by step what I did:

$ emacs --daemon
$ emacsclient -t

In the open Spacemacs terminal session that pops up, SPC q r tied to dotspacemacs/resume-emacs-resume-layouts.
I am now back in the terminal.

Note the last command prompt ($). At this point I would have expected message in the terminal saying Emacs daemon restarted! Use '%s -nw -s %s %s' to reconnect to it. Instead I am back in the terminal and see the third emacs process running in htop, without being able to attach to it and see the usual emacs terminal environment buffers.

This seems like the problematic error

spacemacs buffer error: (beginning-of-buffer)

It seems this error is preventing Emacs init from completely running and thus restart-emacs's startup hook which prints this message is never getting a chance

Hello @danielkrizian, any update on this? Is this still happening?
