Need help debugging weird behavior on go-fuse + macOS + MacFuse 4.x

11

I've been trying to rewrite filesystem mounting layer in https://github.com/kopia/kopia from `bazil.org/fuse` to `go-fuse` (which is excellent, especially v2 API) The port went mostly smoothly, but I've noticed some really...

Handling long filenames on Windows

feat(repository): implement shared async writer pool for object manager
