Well, re-reading my email, it looks aggressive to me now... sorry about

What I meant was basically, that in my mind pre-push or pre-commit are
also local-only things, and they are really useful in that they allow to
block the push or the commit if some conditions are not met (eg. block
commit with trailing whitespace, or block push of unsigned commits).

In pretty much the same way, what I'm really looking for is a way to
“block the fetch” (from a user-visible standpoint) -- like pre-push but
in the opposite direction. I hope such a goal is not an anti-pattern for
hook design?

In order to do this, I first tried updating this tweak-fetch hook patch
from late 2011, and then learned that it would cause too high a load on
servers. Then, while brainstorming another solution, this idea of a
notification-only post-fetch hook arose. But, as I noticed while writing
my previous answer, this suffers the same
issue that you pointed out just after the “*HOWEVER*” in [1]. So that
solution is likely a bad solution too. I guess we'll continue the search
for a good solution in the side-thread with Peff, hoping to figure one out.

That being said about what I meant in my last email, obviously you're
the one who has the say on what goes in or not! And if it's an
anti-feature I'd much rather know it now than after spending a few
nights coding :)

So, what do you think about this use case I'm thinking of? (ie.
“blocking the fetch” like pre-push “blocks the push” and pre-commit
“blocks the commit”?)
