Earlier, "git filter-branch --<options> HEAD" would not update the
working tree after rewriting the branch. This commit fixes it.

The man page for filter-branch still talked about writing the result
to the branch "newbranch". This is hopefully the last place where the
old behaviour was described.

There are a few programs, such as config and diff, which allow running
without a git repository. Therefore, they have to call
setup_git_directory_gently().
However, when GIT_DIR and GIT_WORK_TREE were set, and the current
directory was a subdirectory of the work tree,
setup_git_directory_gently() would return a bogus NULL prefix.
This patch fixes that.

When diff drivers are installed, calling "git diff <tree1>..<tree2>"
calls those drivers. This borks the patch generation of rebase -i.
So use "git diff-tree -p" instead, which does not call diff drivers.

Before this patch the clean target has removed the
configure script that comes with Git tar file.
That made compiling Git for different architectures
inconvenient.
This patch excludes configure from the files to be
deleted by 'make clean' and adds new target 'distclean'
to preserve old functionality.

When calling git-config not from the top level directory of a repository,
it changes directory before trying to open the config file specified
through the --file option, which then fails if the config file was
specified by a relative pathname. This patch adjusts the pathname to
the config file if applicable.

Before this patch, clear_commit_marks() recursed for each parent. This
could be potentially very expensive in terms of stack space. Probably
the only reason that this did not lead to problems is the fact that we
typically call clear_commit_marks() after marking a relatively small set
of commits.
Use (sort of) a tail recursion instead: first recurse on the parents
other than the first one, and then continue the loop with the first
parent.

The unified diff format allows one-line ranges to be abbreviated
by omiting the size. The hunk header "@@ -10,1 +10,1 @@" can be
expressed as "@@ -10 +10 @@", but this wasn't properly parsed in
all cases.
Such abbreviated hunk headers are generated when a one-line change
(add, remove or modify) appears without context; for example
because the file is a one-liner itself or because GIT_DIFF_OPTS
was set to '-u0'. If the user then runs 'git add -i' and enters
the 'patch' command for that file, perl complains about undefined
variables.

This fixes an unnecessary empty line that we add to the log message when
we generate diffs, but don't actually end up printing any due to having
DIFF_FORMAT_NO_OUTPUT set.
This can happen with pickaxe or with rename following. The reason is that
we normally add an empty line between the commit and the diff, but we do
that even for the case where we've then suppressed the actual printing of
the diff.
This also updates a couple of tests that assumed the extraneous empty
line would exist at the end of output.

It turns out that I completely broke "git log --follow" with my recent
patch to revision.c ("Fix revision log diff setup, avoid unnecessary diff
generation", commit b7bb760d5ed4881422673d32f869d140221d3564).
Why? Because --follow obviously requires the diff machinery to function,
exactly the same way pickaxe does.
So everybody is away right now, but considering that nobody even noticed
this bug, I don't think it matters. But for the record, here's the trivial
one-liner fix (well, two, since I also fixed the comment).
Because of the nature of the bug, if you ask for patches when following
(which is one of the things I normally do), the bug is hidden, because
then the request for diff output will automatically also enable the diffs
themselves.
So while "git log --follow <filename>" didn't work, adding a "-p"
magically made it work again even without this fix.

This tests basic functionality and also exercises a bug noticed
by Keith Packard, (prune_cache followed by add_index_entry can
trigger an attempt to realloc a pointer into the middle of an
allocated buffer).
Signed-off-by: Junio C Hamano <gitster@pobox.com>

The index cache is not static, growing as new entries are added. If
entries are added after prune_cache is called, cache will no longer
point at the base of the allocation, and realloc will not be happy.
I verified that this was the only place in the current source which
modified any index_state.cache elements aside from the alloc/realloc
calls in read-cache by changing the type of the element to 'struct
cache_entry ** const cache' and recompiling.
A more efficient patch would create a separate 'cache_base' value to
track the allocation and then fix things up when reallocation was
necessary, instead of the brute-force memmove used here.

We find rename candidates by computing a fingerprint hash of
each file, and then comparing those fingerprints. There are
inherently O(n^2) comparisons, so it pays in CPU time to
hoist the (rather expensive) computation of the fingerprint
out of that loop (or to cache it once we have computed it once).
Previously, we didn't keep the filespec information around
because then we had the potential to consume a great deal of
memory. However, instead of keeping all of the filespec
data, we can instead just keep the fingerprint.
This patch implements and uses diff_free_filespec_data_large
to accomplish that goal. We also have to change
estimate_similarity not to needlessly repopulate the
filespec data when we already have the hash.
Practical tests showed 4.5x speedup for a 10% memory usage
increase.

that the pusher's name is used
Using the name of the committer of the revision at the tip of the
updated ref is not sensible. That information is available in the email
itself should it be wanted, and by supplying a "From", we were

1) Previously, any menu would cause a perl error when entered '0',
which is never a valid option.
2) Entering a bogus choice (like 998 or 4-2) surprisingly caused
the same behavior as if the user had just hit 'enter', which
means to carry out the selected action on the selected items.
Entering such bogus input is now a no-op and the sub-menu

We used to incorrectly start calculating diffs whenever any argument but
'-z' was recognized by the diff options parsing. That was bogus, since not
all arguments result in diffs being needed, so we just waste a lot of time
and effort on calculating diffs that don't matter.
This actually also fixes another bug in "git log". Try this:
git log -C
and notice how it prints an extra empty line in between log entries, even
though it never prints the actual diff (because we didn't ask for any diff
format, so the diff machinery never prints anything).
With this patch, that bogus empty line is gone, because "revs->diff" is
never set. So this isn't just a "wasted time and effort" issue, it's also
a slight semantic fix.

git-am used "git apply -z --index-info" to find the original versions
of the files touched by the diff, to be able to do an inexpensive
three-way merge.
This operation makes only sense in a repository, since the index
information in the diff refers to blobs, which have to be present in
the current repository.
Therefore, teach "git apply" a mode to write out the result as an
index file to begin with, obviating the need for scripts to do it
themselves.
The sole user for --index-info is "git am" is converted to
use --build-fake-ancestor in this patch.
