Re: Make "git clone" less of a deathly quiet experience

BTW, some historical (from the very channel beginning) logs of #git for
fun, profit and late night reading are available at
http://pasky.or.cz/~pasky/cp/%23git/, e.g. the 2006-02-10 early morning
features the King Penguin explaining the deepness and intricacies of
pack files construction! Don't miss the opportunity!

New files won't be world-readable by default, but I hope to get some
irclogger with cutesy web interface set up for #git.


Dear diary, on Sat, Feb 11, 2006 at 06:48:55AM CET, I got a letter
where Junio C Hamano [off-list ref] said that...

Anyway, _something_ like this is definitely needed. It could certainly be 
better (if it showed the same kind of thing that git-unpack-objects did, 
that would be much nicer, but would require parsing the object stream as 
it comes in). But this is  big step forward, I think.

Comments? Hate-mail? Improvements?

It probably should default to quiet if (!isatty(1)).

isatty(2) or something, 1 is in practice always a ref generator. Perhaps
it would be better not to clutter stderr, though; what about directly
opening /dev/tty? Does Cygwin support that?

The real improvement, independent of this client-side patch,
would be to reuse recently generated packs, but that needs
writable cache directory on the server side.  Another thing that
I stumbled upon last time I tried it was that it did not look
totally trivial to modify the csum-file interface so that I can
splice the output from it into two different destinations (one
to cachefile, the other to the consumer).

Yes, I said that on IRC yesterday as well. I don't think even a cache is
needed; just look at the repository and say:

	* while there are packs containing only objects we are going to
	  send, pick the largest one and send it as-is.
	* if there is a pack with more than a 75% (totally arbitrary)
	  overlap with the objects we are going to send, send it as-is.
	* pack the loose objects.
