[Message part 1 (text/plain, inline)]

Hi,

I am using the latest emacs-30 https://github.com/emacs-mirror/emacs/commit/c6077015894dd89c5aa3811bf55d3124394874d0 

The min configuration is as follows:

(add-to-list 'treesit-extra-load-path (expand-file-name "tree-sitter/" user-emacs-directory))

(add-to-list 'load-path "~/.emacs.d/site-lisp/clojure-ts-mode”)

(require 'clojure-ts-mode)

;; debug

(setq debug-on-quit t)

and I only use clojure-ts-mode package

cd ~/.emacs.d/site-lisp

git clone https://github.com/clojure-emacs/clojure-ts-mode.git

Then, after opening Emacs, Open the elong.clj file,

After moving to line 52, delete all the characters following :error-code, then quickly press the spacebar twice. At this point, it freezes.


------------

Sincerely,



Haiyuan Zhang, Vinurs

AFAICT, it doesn't freeze, it eats up memory like crazy.  If you limit
the memory available to the process to some reasonable value, Emacs
will soon enough tell you that memory is exhausted, and will suggest
to save the buffer and exit.

Yuan, can you look into this, please?  I'm not sure it's an Emacs bug,
but who knows?

Yes, I can reproduce this. In fact, it’s not tree-sitter-clojure, but tree-sitter-markdown-inline who caused the hang. I was able to reproduce the hang independently without Emacs. This seems to be the same bug as in https://github.com/tree-sitter/tree-sitter/issues/3620. I’ll update on the GitHub issue with this new repo later.

If you are saying that the fix they installed in tree-sitter didn't
solve the problem, why not take this up with the tree-sitter
developers?

Sorry for the late response. I went over the reproduce recipe again, and at least for me, Emacs doesn’t hang anymore. Maybe your Emacs isn’t picking up the right tree-sitter library?

I tried again with v0.24.4 and emacs 30, and still can’t reproduce this. Haiyuan, if you run 

otool -L <emacs-binary>

What’s the location of libtree-sitter? I’m asking to see if there’s an old tree-sitter library on your system that Emacs is picking up over the new library you installed.

I tried again with v0.24.4 and emacs 30, and still can’t reproduce this. Haiyuan, if you run  

otool -L <emacs-binary>

What’s the location of libtree-sitter? I’m asking to see if there’s an old tree-sitter library on your system that Emacs is picking up over the new library you installed.

Thanks for your patience on this. And actually, you’re right. I can reproduce this now. I couldn’t reproduce it before because I was pressing space too fast. I was messing around with the reproduce steps and found that if I press the two spaces slower, I can reliably reproduce this.

This is baffling because the C reproduce program I built to exactly replicate this recipe doesn’t hang after the fix in tree-sitter. Once I figure out why I’ll send another bug report to tree-sitter. And sorry that this wasn’t fixed.

One more test: can you try tree-sitter 0.25.0 and see if you still see the hang? With the same “technique”, I can reproduce with 0.24.4 but not 0.25.0. That could mean the bug is fixed in 0.25.0.

Hi,
I tried version 0.25.0, and using the same method it doesn't always reproduce the issue, but it still hangs. On the same line, if I repeatedly delete and press space, it also hangs. I just haven't found a consistent way to reproduce it yet.

Thanks. That’s bad news. I’ll also see if I can modify my C program to reproduce this.

Can we have a GDB backtrace when Emacs freezes like that?  If the
freeze is inside tree-sitter, maybe build that with debug symbols, so
that GDB shows information inside the library, and we could then try
to figure out what causes this.

It’s almost certainly tree-sitter. And it’s unlikely for us to find the cause of the hang without considerable knowledge of tree-sitter internals.

Anyway, I’ll start with reproducing it reliably.

Maybe.  But we have the sources of tree-sitter, so nothing prevents us
from trying -- provided that we have the backtrace from the freeze.

Thanks, that will help.
