As promised, this is the "big tool rename" patch. The primary differences
since 0.99.6 are:
(1) git-*-script are no more. The commands installed do not
have any such suffix so users do not have to remember if
something is implemented as a shell script or not.
(2) Many command names with 'cache' in them are renamed with
'index' if that is what they mean.
There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support is expected to be removed in the near

The reverse patch application using "git apply" sometimes is too
rigid. Since the user would get used to resolving conflicting merges
by hand during the normal merge experience, using the same machinery
would be more helpful rather than just giving up.
Cherry-picking and reverting are essentially the same operation.
You pick one commit, and apply the difference that commit introduces
to its own commit ancestry chain to the current tree. Revert applies
the diff in reverse while cherry-pick applies it forward. They share
the same logic, just different messages and merge direction.

This script uses the list of heads and their origin multi-head "git
fetch" left in the $GIT_DIR/FETCH_HEAD file, and makes an octopus
merge on top of the current HEAD using them.
The implementation tries to be strict for the sake of safety. It
insists that your working tree is clean (no local changes) and matches
the HEAD, and when any of the merged heads does not automerge, the
whole process is aborted and tries to rewind your working tree is to
the original state.

When showing only one branch a lot of default output becomes redundant,

Signed-off-by: Junio C Hamano <junkio@cox.net>
The 'git show-branches' command turns out to be reasonably useful,
but painfully slow. So rewrite it in C, using ideas from merge-base
while enhancing it a bit more.
- Unlike show-branches, it can take --heads (show me all my
heads), --tags (show me all my tags), or --all (both).
- It can take --more=<number> to show beyond the merge-base.
- It shows the short name for each commit in the extended SHA1
syntax.
- It can find merge-base for more than two heads.
Examples:
$ git show-branch --more=6 HEAD
is almost the same as "git log --pretty=oneline --max-count=6".
$ git show-branch --merge-base master mhf misc
finds the merge base of the three given heads.
$ git show-branch master mhf misc
shows logs from the top of these three branch heads, up to their
common ancestor commit is shown.
$ git show-branch --all --more=10
is poor-man's gitk, showing all the tags and heads, and
going back 10 commits beyond the merge base of those refs.

This patch renames COPTS to CFLAGS, because it's COPTS that was user
overridable. Also, -Wall is moved there because it's optional. What
was CFLAGS is now ALL_CFLAGS, which users should not override.
Defines are added to DEFINES. Since ALL_CFLAGS is recursively expanded,
it uses the final value of DEFINES.
Implicit rules are made explicit since the implicit rules use CFLAGS
rather than ALL_CFLAGS. I believe that serious projects should not rely
on implicit rules anyway. Percent rules are used because they are used
already and because they don't need the .SUFFIXES target.

to Josef, but I ended up rewriting major parts of his patch, so
bugs are all mine. Also I changed the semantics for the hook
from his original version (which were post-update hook) so that

This adds a new "git bisect" command.
- "git bisect start"
start bisection search.
- "git bisect bad <rev>"
mark some version known-bad (if no arguments, then current HEAD)
- "git bisect good <revs>..."
mark some versions known-good (if no arguments, then current HEAD)
- "git bisect reset <branch>"
done with bisection search and go back to your work (if
no arguments, then "master").
The way you use it is:
git bisect start
git bisect bad # Current version is bad
git bisect good v2.6.13-rc2 # v2.6.13-rc2 was the last version
# tested that was good
When you give at least one bad and one good versions, it will
bisect the revision tree and say something like:
Bisecting: 675 revisions left to test after this
and check out the state in the middle. Now, compile that kernel, and boot
it. Now, let's say that this booted kernel works fine, then just do
git bisect good # this one is good
which will now say
Bisecting: 337 revisions left to test after this
and you continue along, compiling that one, testing it, and depending on
whether it is good or bad, you say "git bisect good" or "git bisect bad",
and ask for the next bisection.
Until you have no more left, and you'll have been left with the first bad
kernel rev in "refs/bisect/bad".
Oh, and then after you want to reset to the original head, do a
git bisect reset
to get back to the master branch, instead of being in one of the bisection
branches ("git bisect start" will do that for you too, actually: it will
reset the bisection state, and before it does that it checks that you're
not using some old bisection branch).
Not really any harder than doing series of "quilt push" and "quilt pop",
now is it?
[jc: This patch is a rework based on what Linus posted to the
list. The changes are:
- The original introduced four separate commands, which was
three too many, so I merged them into one with subcommands.
- Since the next thing you would want to do after telling it
"bad" and "good" is always to bisect, this version does it
automatically for you.
- I think the termination condition was wrong. The original
version checked if the set of revisions reachable from next
bisection but not rechable from any of the known good ones
is empty, but if the current bisection was a bad one, this
would not terminate, so I changed it to terminate it when
the set becomes a singleton or empty.
- Removed the use of shell array variable.

Doing the directory case will require a bit more scripting.. Something like

newfiles=($(git-ls-files | sed ':^$src: s:^$src:$dst:'))
mv $src $dst && git-update-cache --add --remove -- "${oldfiles[@]}" "${newfiles[@]}"

The git-update-server-info command prepares informational files
to help clients discover the contents of a repository, and pull
from it via a dumb transport protocols. Currently, the
following files are produced.
- The $repo/info/refs file lists the name of heads and tags
available in the $repo/refs/ directory, along with their
SHA1. This can be used by git-ls-remote command running on
the client side.
- The $repo/info/rev-cache file describes the commit ancestry
reachable from references in the $repo/refs/ directory. This
file is in an append-only binary format to make the server
side friendly to rsync mirroring scheme, and can be read by
git-show-rev-cache command.
- The $repo/objects/info/pack file lists the name of the packs
available, the interdependencies among them, and the head
commits and tags contained in them. Along with the other two
files, this is designed to help clients to make smart pull
decisions.
The git-receive-pack command is changed to invoke it at the end,
so just after a push to a public repository finishes via "git
push", the server info is automatically updated.
In addition, building of the rev-cache file can be done by a
standalone git-build-rev-cache command separately.

- Built-in sha1_file unpacking knows that a base object of a
