Dirvish produces "error in process sentinel : end of file while parsing"

It's a problem with Dirvish on MacOS.

Hello @jonathanwilner ,

Thank you for bringing this to my attention;

I can't reproduce it on my machine. Can you please enable debugging SPC t d before launching the command which triggers the issue?

Or, more simply, you can start Emacs with:

MINEMACS_DEBUG=1 emacs

And share the backtrace and mention which Emacs version you are using. These can help me track the issue down.

Hi - it's not generating a backtrace at all. :-(

I'm getting a bunch of blank output from Dirvish / Dirvish-preview. Here's the screenshot from the buffers it creates.

Emacs is :
GNU Emacs 30.0.50 (build 1, aarch64-apple-darwin22.4.0, NS appkit-2299.50

Dirvish do create some temporary buffers while generating previews. These should not cause a problem.

I've tested it on my machine, but I can't reproduce a similar behavior! I don't have access to a Mac machine, so I can't test in the exact same conditions.

One caveat though, I've moved to Emacs 29.0.90 for the moment. The last time I've used Emacs 30.0.50 I've noticed some wired messages (not related to dirvish, I didn't try dirvish on Emacs 30 from a while).

In all cases, I think that this issue should be reported to dirvish's developers, specially if you can reproduce it in a minimal setup (using emacs -Q). You can try something like this dirvish-minimal.el:

;; Install
(package-vc-install "https://github.com/alexluigit/dirvish")

;; Use
(use-package dirvish
  :init (dirvish-override-dired-mode)
  :custom
  (dirvish-attributes '(subtree-state file-size vc-state git-msg))
  (dirvish-mode-line-format '(:left (sort file-time symlink) :right (omit yank index)))
  (dirvish-side-width 30)
  (dirvish-fd-default-dir "~/")
  (dirvish-use-header-line t) ; 'global make header line span all panes
  (dirvish-use-mode-line t))

Then run this to try to reproduce the issue in a minimal setup.:

emacs -Q -l dirvish-minimal.el
