I have no idea why they aren't using kqueue but that works on macOS and FreeBSD. It has for years.
replyYou want EVFILT_VNODE with NOTE_WRITE. That's hooked up to VNOP_WRITE in the kernel, the call made to the relevant filesystem to actually perform the write.
I believe you are mistaken. If you are referring to the comment from ArielTM, that's an LLM bot regurgitating your readme.
replyApologies for not being specific.
replyThe specific thing I'm talking about is this: write events don't fire until the file handle is closed. [1] I didn't validate this myself btw, but my original design was certainly trying to use notify events rather than stat polling. My research (heavily AI assisted of course) led me away from that path as platforms differ in behavior and I wanted to avoid that.
If this has been fixed somewhere or there is a better alternative I'd love to use that over polling. Current plan is to move to polling data version for speed + occasional stat for safety. Getting rid of polling was my original goal but i compromised with syscalls.
