Optimize common case of git-rev-list

I took a look at webgit, and it looks like at least for the "projects"
page, the most common operation ends up being basically

git-rev-list --header --parents --max-count=1 HEAD

Now, the thing is, the way "git-rev-list" works, it always keeps on
popping the parents and parsing them in order to build the list of
parents, and it turns out that even though we just want a single commit,
git-rev-list will invariably look up _three_ generations of commits.

It will parse:
 - the commit we want (it obviously needs this)
 - it's parent(s) as part of the "pop_most_recent_commit()" logic
 - it will then pop one of the parents before it notices that it doesn't
   need any more
 - and as part of popping the parent, it will parse the grandparent (again
   due to "pop_most_recent_commit()".

Now, I've strace'd it, and it really is pretty efficient on the whole, but
if things aren't nicely cached, and with long-latency IO, doing those two
extra objects (at a minimum - if the parent is a merge it will be more) is
just wasted time, and potentially a lot of it.

19 years agogit-fetch-pack: avoid unnecessary zero packing
Linus Torvalds [Tue, 18 Oct 2005 18:35:17 +0000 (11:35 -0700)]
git-fetch-pack: avoid unnecessary zero packing

If everything is up-to-date locally, we don't need to even ask for a
pack-file from the remote, or try to unpack it.

This is especially important for tags - since the pack-file common commit
logic is based purely on the commit history, it will never be able to find
a common tag, and will thus always end up re-fetching them.

Especially notably, if the tag points to a non-commit (eg a tagged tree),
the pack-file would be unnecessarily big, just because it cannot any most
recent common point between commits for pruning.

Short-circuiting the case where we already have that reference means that
we avoid a lot of these in the common case.

NOTE! This only matches remote ref names against the same local name,
which works well for tags, but is not as generic as it could be. If we
ever need to, we could match against _any_ local ref (if we have it, we
have it), but this "match against same name" is simpler and more
efficient, and covers the common case.

Renaming of refs is common for branch heads, but since those are always
commits, the pack-file generation can optimize that case.

In some cases we might still end up fetching pack-files unnecessarily, but
this at least avoids the re-fetching of tags over and over if you use a
regular

git fetch --tags ...

which was the main reason behind the change.

Originally, format-patch took either one rev, or two revs:

    format-patch rev1
    format-patch rev1 rev2

The first format was a short-hand for "format-patch rev1 HEAD"
(i.e. rev2==HEAD).  What this meant was to find commits that are
in branch rev2 that has not been merged to branch rev1.

The above notation is still supported, but now it takes sequence
of "from1..to1 from2..to2 ...".  In short, the second format has
become a short-hand for "format-patch rev1..rev2".  Commits in
to1 but not in from1, to2 but not in from2, ... are formatted as
emailable patches.

With this, cherry-picking from other branch can be written as:

    git-format-patch -k --stdout master..branch1 master..branch2 |
    git-am -k -3
