"Computing the diff for you" - editor hangs

[QuintinS]

I found split-diff to solve a problem I was having, since it seemed like the ideal tool.

I used as described... opened the file, ran "split diff: toggle"... but all I get is a loading message saying "Computing the diff for you" which crashes the editor, necessitating a force-quit.

I've seen other issues with similar results dating back to 2016.

Atom: 1.19.2
Split-diff: 1.5.1

@QuintinS any chance you can reproduce with the console open? (ctrl+shift+p then search dev tools) Then if you run split-diff, does the console say anything? Does it happen on all files or specific files? Thanks

@mupchrch I'm also seeing this issue.

I ran it with dev tools open and the only thing I see is this but that was there before running split diff

IntersectionObserver.observe(target): target element is not a descendant of root.

It's seems to only happen to me on large files eg I'm trying to diff a file that's 52,000 lines.

In task manager there is a atom process that's at 9.9% CPU and 700MB of RAM. the usage is only hitting one process on the 12 the system has (ryzen system).

I let it run on the "Computing the diff for you" for 45 mins then force quite atom.

I am experiencing the same issue but with split-diff 1.5.2
Using console shows this
