When we run a regular "git fetch" without arguments, we
update the tracking refs according to the configured
refspec. However, when we run "git fetch origin master" (or
"git pull origin master"), we do not look at the configured
refspecs at all, and just update FETCH_HEAD.
We miss an opportunity to update "refs/remotes/origin/master"
(or whatever the user has configured). Some users find this
confusing, because they would want to do further comparisons
against the old state of the remote master, like:
$ git pull origin master
$ git log HEAD...origin/master
In the currnet code, they are comparing against whatever
commit happened to be in origin/master from the last time
they did a complete "git fetch". This patch will update a
ref from the RHS of a configured refspec whenever we happen
to be fetching its LHS. That makes the case above work.
The downside is that any users who really care about whether
and when their tracking branches are updated may be
surprised.

We have three sequential tests for for whether tracking refs
are updated by various fetches and pulls; the first two
should not update the ref, and the third should. Each test
depends on the state left by the test before.
This is fragile (a failing early test will confuse later
tests), and means we cannot add more "should update" tests
after the third one.
Let's instead save the initial state before these tests, and
then reset to a known state before running each test.

t5004: avoid using tar for checking emptiness of archive
t5004: ignore pax global header file
mergetools/kdiff3: do not use --auto when diffing
transport-helper: trivial style cleanup
Test 2 of t5004 checks if a supposedly empty tar archive really
contains no files. 24676f02 (t5004: fix issue with empty archive test
and bsdtar) removed our commit hash to make it work with bsdtar, but
the test still fails on NetBSD and OpenBSD, which use their own tar
that considers a tar file containing only NULs as broken.
Here's what the different archivers do when asked to create a tar
file without entries:
$ uname -v
NetBSD 6.0.1 (GENERIC)
$ gtar --version | head -1
tar (GNU tar) 1.26
$ bsdtar --version
bsdtar 2.8.4 - libarchive 2.8.4
$ : >zero.tar
$ perl -e 'print "\0" x 10240' >tenk.tar
$ sha1 zero.tar tenk.tar
SHA1 (zero.tar) = da39a3ee5e6b4b0d3255bfef95601890afd80709
SHA1 (tenk.tar) = 34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
$ : | tar cf - -T - | sha1
da39a3ee5e6b4b0d3255bfef95601890afd80709

34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
$ : | bsdtar cf - -T - | sha1
34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
So NetBSD's native tar creates an empty file, while GNU tar and bsdtar
both give us 10KB of NULs -- just like git archive with an empty tree.
Now let's see how the archivers handle these two kinds of empty tar
files:
$ tar tf zero.tar; echo $?
tar: Unexpected EOF on archive file
1
$ gtar tf zero.tar; echo $?
gtar: This does not look like a tar archive
gtar: Exiting with failure status due to previous errors
2
$ bsdtar tf zero.tar; echo $?
0
$ tar tf tenk.tar; echo $?
tar: Cannot identify format. Searching...
tar: End of archive volume 1 reached
tar: Sorry, unable to determine archive format.
1
$ gtar tf tenk.tar; echo $?
0
$ bsdtar tf tenk.tar; echo $?
0
NetBSD's tar complains about both, bsdtar happily accepts any of them
and GNU tar doesn't like zero-length archive files. So the safest
course of action is to stay with our block-of-NULs format which is
compatible with GNU tar and bsdtar, as we can't make NetBSD's native
tar happy anyway.
We can simplify our test, however, by taking tar out of the picture.
Instead of extracting the archive and checking for the non-presence of
files, check if the file has a size of 10KB and contains only NULs.
This makes t5004 pass on NetBSD and OpenBSD.

Add a test to verify the emptiness of an archive by extracting its
contents. Don't run this test if the version of tar doesn't support
archives containing only a comment header, though.
The existing check 'tar archive of empty tree is empty' used to work
like that (minus the tar capability check) but was changed to depend
on the exact representation of empty tar files created by git archive
instead of on the behaviour of tar in order to avoid issues with
different tar versions.
The different approaches test different things: The existing one is
for empty trees, for which we know the exact expected output and thus
we can simply check it without extracting; the new one is for commits
with empty trees, whose archives include stamps and so the more
"natural" check by extraction is a better fit because it focuses on
the interesting aspect, namely the absence of any archive entries.

Typing 'HEAD' is tedious, especially when we can use '@' instead.
The reason for choosing '@' is that it follows naturally from the
ref@op syntax (e.g. HEAD@{u}), except we have no ref, and no
operation, and when we don't have those, it makes sens to assume
'HEAD'.
So now we can use 'git show @~1', and all that goody goodness.

When this happens, we want to handle the entry as a directory and not

When a reference that existed in the packed-refs file is deleted, the
packed-refs file must be rewritten. Previously, the file was
rewritten without any peeled refs, even if the file contained peeled
refs when it was read. This was not a bug, because the packed-refs
file header didn't claim that the file contained peeled values. But
it had a performance cost, because the repository would lose the
benefit of having precomputed peeled references until pack-refs was
run again.
Teach repack_without_ref() to write peeled refs to the packed-refs
file (regardless of whether they were present in the old version of
the file).
This means that if the old version of the packed-refs file was not
fully peeled, then repack_without_ref() will have to peel references.
To avoid the expense of reading lots of loose references, we take two
shortcuts relative to pack-refs:
* If the peeled value of a reference is already known (i.e., because
it was read from the old version of the packed-refs file), then
output that peeled value again without any checks. This is the
usual code path and should avoid any noticeable overhead. (This is
different than pack-refs, which always re-peels references.)
* We don't verify that the packed ref is still current. It could be
that a packed references is overridden by a loose reference, in
which case the packed ref is no longer needed and might even refer
to an object that has been garbage collected. But we don't check;
instead, we just try to peel all references. If peeling is
successful, the peeled value is written out (even though it might
not be needed any more); if not, then the reference is silently
omitted from the output.
The extra overhead of peeling references in repack_without_ref()
should only be incurred the first time the packed-refs file is written
by a version of Git that knows about the "fully-peeled" attribute.

Stop emitting an error message when deleting a packed reference if we
find another dangling packed reference that is overridden by a loose
reference. See the previous commit for a longer explanation of the
issue.
We have to be careful to make sure that the invalid packed reference
really *is* overridden by a loose reference; otherwise what we have
found is repository corruption, which we *should* report.
Please note that this approach is vulnerable to a race condition
similar to the race conditions already known to affect packed
references [1]:
* Process 1 tries to peel packed reference X as part of deleting
another packed reference. It discovers that X does not refer to a
valid object (because the object that it referred to has been
garbage collected).
* Process 2 tries to delete reference X. It starts by deleting the
loose reference X.
* Process 1 checks whether there is a loose reference X. There is not
(it has just been deleted by process 2), so process 1 reports a
spurious error "X does not point to a valid object!"
The worst case seems relatively harmless, and the fix is identical to
the fix that will be needed for the other race conditions (namely
holding a lock on the packed-refs file during *all* reference
deletions), so we leave the cleaning up of all of them as a future
project.

A packed reference can be overridden by a loose reference, in which
case the packed reference is obsolete and is never used. The object
pointed to by such a reference can be garbage collected. Since
d66da478f2, this could lead to the emission of a spurious error
message:
error: refs/heads/master does not point to a valid object!
The error is generated by repack_without_ref() if there is an obsolete
dangling packed reference in packed-refs when the packed-refs file has
to be rewritten due to the deletion of another packed reference. Add
a failing test demonstrating this problem and some passing tests of

Most test results go in $TEST_OUTPUT_DIRECTORY, but the output files for

As a result of this, the valgrind/analyze.sh script may no longer
inspect the correct files so it is also updated to respect
$TEST_OUTPUT_DIRECTORY by adding it to GIT-BUILD-OPTIONS. This may be a
