"error in process sentinel: End of file during parsing" during ANY async-start, or dired-async command

[Matt812g]

I think this may be similar to #131 (comment)

• OS: Termux 0.118.0 (118), loaded from f-droid
• GNU Emacs 29.1 (build 1, aarch64-unknown-linux-android) of 2023-09-23, loaded from pkg in termux
• async Version: 1.9.8, loaded from melpa using use-package and straight.el.

When I run this code:

(defvar scratch-1 nil)
(progn
  (setq async-debug t)
  (setq scratch-1 nil)
  (async-start
   `(lambda ()
      (message "yes")
      1)
   (lambda (result)
     (setq scratch-1 result))
   ))
;; result eventually stored in this global variable
(describe-variable scratch-1)

I get this error:

error in process sentinel: End of file during parsing

I'm pretty sure that is not working as intended?

Any ideas how to get around this? I can't live without async -- especially dired-async, which also gives this error.

Thanks!

No, both (your code and dired-async) are working as expected on GnuLinux. Perhaps try to reinstall or recompile?

I just tried copying a file in dired. *emacs* contains:

(async-signal (end-of-file))

*Messages* contains:

Copy proceeding asynchronously... error in process sentinel: async-handle-result: End of file during parsing error in process sentinel: End of file during parsing

This is expected? (Seems more likely to me that this is related to something weird in the termux environment that the dired-async code doesn't handle, but I could be wrong.) I'll try reinstalling, but this was a fresh install, so I don't have much faith in it. Thanks

Of course no, you should have no errors at all.

Also, all was working fine on another GnuLinux (alpine) system just a day before.

No changes have been done recently, so if all was working fine there yesterday it should work fine today.

So, it seems to me that dired-async is NOT working as expected. Yes?

If you still have an error on the android platform, of course there is something wrong, in this case you should report as an emacs-bug to have help from the developer in charge of the android port of emacs. If it is working fine on GnuLinux it should work fine on other platforms.

Of course no!

Perhaps yes.

Interestingly, I have several functions that use start-process with sentinels (as opposed to make-process, which emacs-async uses). Those work fine.

I also am not doing any sending of messages, and I do not have filters set, though. I'm thinking it might be that which is the problem. If I have time, I will look at that deeper. I wonder if there is an issue with utf or something?

I have posted a conversation here, as well:
