Subject: Re: Watchman support for git

Message-ID: <CACsJy8CDGP1QwX4C3yKVUOw3h90EcLSXXXy=t6XFSVOrVjxA4A@mail.gmail.com> (raw)

One more thing I think we can solve with watchman is the racy
timestamp issue (see 29e4d36 and 407c8eb). Basically if a file is
updated within a second (and the system only supports timestamp
granuarity down to a second) then git can't know if a file is changed
by comparing stat data, so it compares content anyway. With watchman,
I think we know that a file is updated or not and can disable racy
test. How often this happens and whether it is worth supporting is
something to think about.
