Especially with the new index format to come, it is more appropriate
to encapsulate more into check_packed_git_idx() and assume less of the
index format in struct packed_git.
To that effect, the index_base is renamed to index_data with void * type
so it is not used directly but other pointers initialized with it. This
allows for a couple pointer cast removal, as well as providing a better
generic name to grep for when adding support for new index versions or
formats.
And index_data is declared const too while at it.

The 'use packed deltified objects' test was flawed as it failed to

This patch adds support for a dummy remote '.' to avoid having
to declare a fake remote like
[remote "local"]
url = .
fetch = refs/heads/*:refs/heads/*
Such a builtin remote simplifies the operation of "git-fetch",
which will populate FETCH_HEAD but will not pretend that two
repositories are in use, will not create a thin pack, and will
not perform any useless remapping of names. The speed
improvement is around 20%, and it should improve more if
"git-fetch" is converted to a builtin.
To this end, git-parse-remote is grown with a new kind of
remote, 'builtin'. In git-fetch.sh, we treat the builtin remote
specially in that it needs no pack/store operations. In fact,
doing git-fetch on a builtin remote will simply populate
FETCH_HEAD appropriately.
The patch also improves of the --track/--no-track support,
extending it so that branch.<name>.remote items referring '.'
can be created. Finally, it fixes a typo in git-checkout.sh.

This uses diff-tree --quiet machinery to terminate the internal
diff-tree between a commit and its parents via revs.pruning (not
revs.diffopt) as soon as we find enough about the tree change.
With respect to the optionally given pathspec, we are interested
if the tree of commit is identical to the parent's, only adds
new paths to the parent's, or there are other differences. As
soon as we find out that there is one such other kind of
difference, we do not have to compare the rest of the tree.
Because we do not call standard diff_addremove/diff_change, we
instruct the diff-tree machinery to stop early by setting
has_changes when we say we found the trees to be different.

This teaches git-diff-files, git-diff-index and git-diff-tree

Signed-off-by: Junio C Hamano <junkio@cox.net>
This adds the command line option 'quiet' to tell 'git diff-*'
that we are not interested in the actual diff contents but only
want to know if there is any change. This option automatically
turns --exit-code on, and turns off output formatting, as it
does not make much sense to show the first hit we happened to
have found.
The --quiet option is silently turned off (but --exit-code is
still in effect, so is silent output) if postprocessing filters
such as pickaxe and diff-filter are used. For all practical
purposes I do not think of a reason to want to use these filters
and not viewing the diff output.
The backends have not been taught about the option with this patch.
That is a topic for later rounds.

Previously git-describe would output lines of the form
v1.1.1-gf509d56
The update hook found the dash and stripped it off using
sed 's/-g.*//'
The remainder was then used as the previous tag name.
However, git-describe has changed format. The output is now of the form
v1.1.1-23-gf509d56
The above sed fragment doesn't strip the middle "-23", and so the
previous tag name used would be "v1.1.1-23". This is incorrect.
Since the hook script was written, git-describe now gained support for
"--abbrev=0", which it uses as a special flag to tell it not to output
anything other than the nearest tag name. This patch fixes the problem,
and prevents any future recurrence by using this new flag rather than
sed to find the previous tag.

If you use scanf or sscanf to parse integers, your code probably
accepts bogus inputs. For example, builtin-grep (aka git-grep) uses
sscanf(scan, "%u", &num) to parse the integer argument to -A, -B, -C.
Currently, "-C 1,000" and "-C 4294967297" are both treated just like
"-C 1":
$ git-grep -h -C 4294967297 juggle
out and you may find it easier to switch back and forth if you
juggle multiple lines of development simultaneously. Of
course, you will pay the price of more disk usage to hold
The obvious fix is to use strtoul instead. But using a bare strtoul is
too messy, at least when done properly, so I've added a wrapper function.
The new function in the patch below belongs elsewhere if it would be
useful in replacing any of the four remaining uses of sscanf.
One final note: With this change, I get a slightly different
diagnostic depending on the context size:
$ ./git-grep -h -C 4294967296 juggle
fatal: 4294967296: invalid context length argument
[Exit 128]
$ ./git-grep -h -C 4294967295 juggle
grep: 4294967295: invalid context length argument
[Exit 1]
A common convention that makes it easy to identify the source
of a diagnostic is to include the program name before the first ":".
Whether that should be "git" or "git-grep" is another question.
Using "grep" or "fatal" is misleading.

After waiting for about 20 seconds, I started getting worried,
thinking that the recent revision traversal updates might have
had an unintended side effect.
Not so. "git shortlog" acts as a filter when no revs are given,
unlike "git log" which defaults to HEAD. It was reading from
its standard input.
