Thanks! And yes, I'll have a blog post on it. It is currently scheduled to appear on Wednesday on the GitHub blog. The new `git fsmonitor--daemon` is mostly shared code but with custom "backends" for each platform hidden a small API. Yes, the Mac backend is built using FSEvents. The Windows backend uses ReadDirectoryChangesW. In both cases, the backend has a thread dedicated to receiving these events/notifications from the kernel, normalizing them, and queuing them for future client requests. For sanity reasons, I had to draw the line at two platforms in the initial implementation. There have been discussions about doing a Linux version using either inotify or fanotify, but that work has not started. (And $dayjob might keep me busy for a while on other things, so I'm open to others picking up that work.) It shouldn't be too hard given the API boundary and threading that I set up. Likewise, for BSD.

Good that you are on HN now and thanks for this message. I ended up fetching git 2.37 (from whatever the default Ubuntu impish is at, I believe 2.32) (I don't know any benchmarking tools for `git(1)`, if your or anyone else does I'm all ears). I opened up `tig(1)` and `gitui(1)` in a large repo, stuff feels snappier. It could be a placebo. When trying to track where it could be coming from, I have trouble pinning it down: - 2.33.0: https://github.com/git/git/blob/v2.33.0/Documentation/RelNotes/2.33.0.txt https://github.com/git/git/blob/v2.33.0/Documentation/RelNot... - 2.34.0: https://github.com/git/git/blob/v2.34.0/Documentation/RelNotes/2.34.0.txt https://github.com/git/git/blob/v2.34.0/Documentation/RelNot... - 2.35.0: https://github.com/git/git/blob/v2.35.0/Documentation/RelNotes/2.35.0.txt https://github.com/git/git/blob/v2.35.0/Documentation/RelNot... - 2.36.0: https://github.com/git/git/blob/v2.36.0/Documentation/RelNotes/2.36.0.txt https://github.com/git/git/blob/v2.36.0/Documentation/RelNot... - 2.37.0: https://github.com/git/git/blob/v2.37.0/Documentation/RelNotes/2.37.0.txt https://github.com/git/git/blob/v2.37.0/Documentation/RelNot... This is a VCS that's getting a lot of care given to it.
