It's more than a dynamic sparse-checkout because the same list is also

won't find new/untracked files unless they are specifically added to the

OK. I'm not at all interested in carrying maintenance burden for some
software behind closed doors. I could see values in having a more
flexible sparse checkout but this now seems like very tightly designed
for GVFS. So unless there's another use case (preferably open source)
for this, I don't think this should be added in git.git.

I should point out that VFS for Git is an open-source project and will
likely have larger use than just at Microsoft.  There are both Windows
and Mac clients and there are plans for a Linux client as well.
Ideally, it would work with an unmodified upstream Git, which is (I
assume) why Ben is sending this series.

Ah I didn't know that. Thank you. I'll have to look at this GVFS some time then.

If we're going to support GVFS though, I think there should be a big
(RFC perhaps) series that includes everything to at least give an
overview what the end game looks like. Then it could be split up into
smaller series.


We've always had the goal of not needing a fork at all and are continually working to bring the list of differences to zero but in the mean time, you can see the entire set of changes we've made here [1].

If you look, most of them are changes we are already in process of submitting to git (ie midx, tracing, etc) or patches we fast tracked from master to our branch (your unpack_trees() optimizations for example).

Most of the others are small tweaks and features for performance or to smooth integration issues. This RFC contains the core changes that were required to enable VFS for Git.
