Hanging on FreeBSD

[duncan-bayne]

First up, thanks for exec-path-from-shell, it's been very helpful for me over the years.

However, it doesn't seem to work on FreeBSD (or at least, my FreeBSD installation). If I call (exec-path-from-shell-initialize) from my config, Emacs hangs indefinitely (though I can still abort with C-g).

I'm currently working around it with:

(unless (eq system-type 'berkeley-unix)
  (when (memq window-system '(mac ns x))
    (exec-path-from-shell-initialize))

  (when (daemonp)
    (exec-path-from-shell-initialize)))

System details:

• FreeBSD 15.1-RELEASE
• GNU Emacs 30.2

Okay that's interesting. It isn't hanging indefinitely. Eventually - after >90s on a fast machine, it completes, and the path seems to be set correctly. Now suspect something might be borked in my configuration; investigating.

Ah, no, it unblocks when I run truss on it 🤯

Have got it working for me for now with a fork:

https://github.com/duncan-bayne/exec-path-from-shell/tree/135-freebsd-fix

... and related config change:

Hoping to spend some time debugging it tonight, and submit a PR that actually fixes the problem (i.e. doesn't just remove -i 🙃)

You might find that something in your interactive shell config is trying to read from the tty, and then times out, or something silly like that. It's unlikely to be down to exec-path-from-shell. Removing -i via your config (see the README) is often a good idea anyway. At least with zsh, there's .zshenv and .zshrc, and it's good practice to set PATH etc in the former, which is still read by the shell at startup even without -i.
