commit: record buffer length in cache
Most callsites which use the commit buffer try to use the
cached version attached to the commit, rather than
re-reading from disk. Unfortunately, that interface provides
only a pointer to the NUL-terminated buffer, with no
indication of the original length.
For the most part, this doesn't matter. People do not put
NULs in their commit messages, and the log code is happy to
treat it all as a NUL-terminated string. However, some code
paths do care. For example, when checking signatures, we
want to be very careful that we verify all the bytes to
avoid malicious trickery.
This patch just adds an optional "size" out-pointer to
get_commit_buffer and friends. The existing callers all pass
NULL (there did not seem to be any obvious sites where we
could avoid an immediate strlen() call, though perhaps with
some further refactoring we could).

Let's provide a pair of helpers, "get" and "unuse", that let

buffer when possible, and otherwise load from disk using
read_sha1_file.
Note that we also need to add a "get_cached" variant which
returns NULL when we do not have a cached buffer. At first
glance this seems to defeat the purpose of "get", which is
to always provide a return value. However, some log code

provide a helper to free commit buffer
This converts two lines into one at each caller. But more
importantly, it abstracts the concept of freeing the buffer,
which will make it easier to change later.
Note that we also need to provide a "detach" mechanism for a
tricky case in index-pack. We are passed a buffer for the
object generated by processing the incoming pack. If we are
not using --strict, we just calculate the sha1 on that
buffer and return, leaving the caller to free it. But if we
are using --strict, we actually attach that buffer to an
object, pass the object to the fsck functions, and then
detach the buffer from the object again (so that the caller
can free it as usual). In this case, we don't want to free
the buffer ourselves, but just make sure it is no longer
associated with the commit.
Note that we are making the assumption here that the
attach/detach process does not impact the buffer at all
(e.g., it is never reallocated or modified). That holds true
now, and we have no plans to change that. However, as we
abstract the commit_buffer code, this dependency becomes
less obvious. So when we detach, let's also make sure that
we get back the same buffer that we gave to the

We can push this check down into diff_setup_done, which is

the following error:

sees a git version of at least 1.7.0 (which is the version in which the
--show-toplevel option was introduced). But "package vsatisfies" returns
false when the major version changes, which is not what we want here.
Fix that for both places where the git version is checked using vsatisfies
by appending a '-' to the version number. This tells vsatisfies that a
change of the major version is not considered to be a problem, as long as
the new major version is larger. This is done for both the place that
caused the reported bug and another spot where the git version is tested
for another feature.

run_diff_files: do not look at uninitialized stat data
If we try to diff an index entry marked CE_VALID (because it
was marked with --assume-unchanged), we do not bother even
running stat() on the file to see if it was removed. This
started long ago with 540e694 (Prevent diff machinery from
examining assume-unchanged entries on worktree, 2009-08-11).
However, the subsequent code may look at our "struct stat"
and expect to find actual data; currently it will find
whatever cruft was left on the stack. This can cause
problems in two situations:
1. We call match_stat_with_submodule with the stat data,
so a submodule may be erroneously marked as changed.
2. If --find-copies-harder is in effect, we pass all
entries, even unchanged ones, to diff_change, so it can
list them as rename/copy sources. Since we found no
change, we assume that function will realize it and not
actually display any diff output. However, we end up
feeding it a bogus mode, leading it to sometimes claim
there was a mode change.
We can fix both by splitting the CE_VALID and regular code
paths, and making sure only to look at the stat information
in the latter. Furthermore, we push the declaration of our
"struct stat" down into the code paths that actually set it,
so we cannot accidentally access it uninitialized in future
code.

git-show: fix 'git show -s' to not add extra terminator after merge commit
When git show -s is called for merge commit it prints extra newline
after any merge commit. This differs from output for commits with one
parent. Fix it by more thorough checking that diff output is disabled.
The code in question exists since commit 3969cf7db1. The additional
newline is really needed for cases when patch is requested, test
t4013-diff-various.sh contains cases which can demonstrate behavior when
the condition is restricted further.
Tests:
Added merge commit to 'set up a bit of history' case in t7007-show.sh to
cover the fix.
Existing tests are updated to demonstrate the new behaviour. Earlier,
the tests that used "git show -s --pretty=format:%s", even though
"--pretty=format:%s" calls for item separator semantics and does not ask
for the terminating newline after the last item, expected the output to
end with such a newline. They were relying on the buggy behaviour. Use
of "--format=%s", which is equivalent to "--pretty=tformat:%s" that asks
for a terminating newline after each item, is a more realistic way to
use the command.
In the test 'merge log messages' the expected data is changed, because
it was explicitly listing the extra newline. Also the msg.nologff and
msg.nolognoff expected files are replaced by one msg.nolog, because they
were diffing because of the bug, and now there should be no difference.
