Hi list,
A week ago or so, I opened a Python file in Emacs and saw Emacs crash hard.
Bisecting my init file, I found that the culprit was tree-sitter. As it turns
out, some change was made in tree-sitter that caused the ABI to change, and when
I upgraded my distro's tree-sitter package, the new ABI caused Emacs to crash.
There is a thread about this issue on the tree-sitter GitHub page:
https://github.com/tree-sitter/tree-sitter/issues/3296
The consensus there seems to be, however, that the current problem should not be
solved by the tree-sitter project, but rather by the relevant Linux
distributions and/or by Emacs itself.
A bug has been opened for Arch Linux (the distro I'm using):
https://gitlab.archlinux.org/archlinux/packaging/packages/emacs/-/issues/2
That issue, however, is labelled with "status:waiting-upstream", which suggests
that nothing's going to happen until the tree-sitter project does something.
Which is not going to happen, I fear, because the tree-sitter issue has been
closed.
Since I haven't seen the issue mentioned here and given that it was suggested it
might be an Emacs issue, I wanted to ask the opinion of the maintainers: can
this be considered an Emacs bug, or is it really something that should be solved
upstream?
TIA

We cannot do anything about this; see bug#70438. The tree-sitter
developers changed the ABI without bumping up the ABI version.
Moreover, they think that's perfectly okay, since tree-sitter is
"still in version 0.x". Because they didn't bump the ABI version,
Linux distros didn't bother to update Emacs they distribute, and the
result is crashes.
The only thing you can do is rebuild Emacs with the updated
tree-sitter (which is AFAIU the distros will do now , and will then
provide fixed packages), or downgrade your tree-sitter library to
version before the ABI change, 0.22.2.

Hi Eli,
Thanks for your reply. Luckily, Arch's Emacs package was updated today and the
problem is resolved.

I tried searching the bugs list, but couldn't find anything. Guess my search-foo
is sub-par...

From what I understand reading the Github issue, it seems that the tree-sitter
devs are slowly starting to understand that this is not a good idea.

I do hope that they will come around. Because it's _definitely_ not a
good idea, for such a popular library.
