Emacslient closes whenever i call sudo-edit

[rien333]

I run emacs as a server, and running sudo-edit closes emacs whenever I run it. It doesn't crash or alter emacs in anyway, it's only that I'm back at my shell and have to rerun my emacs command. I can then edit the files as a sudo user like normal.

I can't reproduce this; can you give full instructions on how to reproduce starting from a clean (-q) emacs server?

[rien333]

Can't reproduce with a clean server either, I'll try and see what the problem is.
Oddly enough running

emacs-26.1 --daemon -q 

does now trigger the undesired behavior described in my first post. The same goes for emacs with my whole init.el file commented out. (I'm running the stable emacs from the Arch Linux repos btw, I don't remember whether I had this problem on macOS as well, but I could check)

Disregard my previous comment, running emacs-26.1 --daemon -q and then manually loading sudo-edit.el seems to work now. Nevertheless, commenting my whole init.el still displays the problematic behavior outlined above when invoking M-x sudo-edit. @nflath any ideas?

[nflath]

Possibly something in your .emacs?

Same problem here. It seems to close if opening in a terminal, but just hangs if on a separate frame. All instances hang, but C-g brings it back. Any thoughts?

[rien333]

I also still experience this. If I find the time, I'll try nflaths suggestion and see if something in my global .emacs folder is causing the problem, as I already established that the problem seems to persist when commenting out all of my init.el (probably not, given that it is not super populated). @someonewithpc does the problem still persist when you comment out all of your init.el and then load sudo-edit manually?

As a work around, I now generally use this function/alias E (which pairs nicely with aliasing emacs to e) to do my sudo edits:

function E
    env SUDO_EDITOR="emacsclient -t -a emacs" sudoedit $argv
end

(fish syntax, but conversion to bash should be trivial)

I can reproduce this with no .emacs or .emacs.d at all. I’m using Emacs 27.1. For reproduction, it’s important that I specify the file on the emacsclient command line.

1. emacs --daemon
2. emacsclient -c /etc/fstab
3. M-x load-library /path/to/sudo-edit.el
4. M-x sudo-edit causes emacsclient to close.

Some variants that might help shed light on what’s going on:

• If I open two emacsclients to different files in step 2, then step 4 closes the current emacsclient, prompts for the sudo password in the other one, and opens the current file there.
• If I open two emacsclients to the same file in step 2, then step 4 closes them both.
• If I visit a different file with C-x C-f before invoking sudo-edit, it doesn’t close anything and works as expected.

I think the problem is with the function find-alternate-file, but I don't know why:

1. emacs --daemon -q
2. emacsclient -c /etc/fstab
3. And M-x eval-expression this (find-alternate-file (concat "/sudo:root@localhost:" buffer-file-name))
