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.

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
$ : | gtar cf - -T - | sha1
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.
$ 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.

Versions of tar that don't know pax headers -- like the ones in NetBSD 6
and OpenBSD 5.2 -- extract them as regular files. Explicitly ignore the
file created for our global header when checking the list of extracted
files, as this is normal and harmless fall-back behaviour. This fixes
test 3 of t5004 on these platforms.

Commit d24fbca (Remove Git's support for smoke testing - 2011-12-23)
removed the smoke test support from the test suite but it was
re-added by commit 342e9ef (Introduce a performance testing

mis-rebase, since re-adding the smoke testing infrastructure does
not relate to the subject of that commit.

This adds one test or comment for each subcommand of git-remote
according to its current documentation. All but 'set-branches' and
'update' are listed as taking only a fixed number of arguments; for
those we can write a test with one more (bogus) argument, and see if
the command notices that.
They fail on several counts: 'add' does not check for extra arguments,
and 'show' and 'prune' actually iterate over remotes (i.e., take any
number of args). We'll fix them in the next two patches.
The -f machinery is only there to make the tests readable while still
ensuring they pass as a whole, and will be removed in the final patch.

When "cat-file -p" prints commits, it shows them in their
raw format, since git's format is already human-readable.
For tags, however, we print the whole thing raw except for
one thing: we convert the timestamp on the tagger line into a
human-readable date.
This dates all the way back to a0f15fa (Pretty-print tagger
dates, 2006-03-01). At that time there was no other way to
pretty-print a tag. These days, however, neither of those
matters much. The normal way to pretty-print a tag is with
"git show", which is much more flexible than "cat-file -p".
Commit a0f15fa also built "verify-tag --verbose" (and
subsequently "tag -v") around the "cat-file -p" output.
However, that behavior was lost in commit 62e09ce (Make git
tag a builtin, 2007-07-20), and we went back to printing
the raw tag contents. Nobody seems to have noticed the bug
since then (and it is arguably a saner behavior anyway, as
it shows the actual bytes for which we verified the
signature).
Let's drop the tagger-date formatting for "cat-file -p". It
makes us more consistent with cat-file's commit
pretty-printer, and as a bonus, we can drop the hand-rolled
tag parsing code in cat-file (which happened to behave
inconsistently with the tag pretty-printing code elsewhere).
This is a change of output format, so it's possible that
some callers could considered this a regression. However,
the original behavior was arguably a bug (due to the
inconsistency with commits), likely nobody was relying on it
(even we do not use it ourselves these days), and anyone
relying on the "-p" pretty-printer should be able to expect
a change in the output format (i.e., while "cat-file" is
plumbing, the output format of "-p" was never guaranteed to
be stable).

specified, we do not remove the trash directory once the tests are
complete (remove_trash is set to $TRASH_DIRECTORY).

When setting up a "half-auth" repository in which reads can
be done anonymously but writes require authentication, it is
best if the server can require authentication for both the
ref advertisement and the actual receive-pack POSTs. This
alleviates the need for the admin to set http.receivepack in
the repositories, and means that the client is challenged
for credentials immediately, instead of partway through the
push process (and git clients older than v1.7.11.7 had
trouble handling these challenges).
Since detecting a push during the ref advertisement requires
matching the query string, and this is non-trivial to do in
Apache, we have traditionally punted and instructed users to
just protect "/git-receive-pack$". This patch provides the
mod_rewrite recipe to actually match the ref advertisement,
which is preferred.
While we're at it, let's add the recipe to our test scripts
so that we can be sure that it works, and doesn't get broken
(either by our changes or by changes in Apache).

The loop that fills in the buffers that are later passed to the merge
driver exits early when not all stages of a path are present in the index.
But since the buffer pointers are not initialized in advance, the
subsequent accesses are undefined.
Initialize buffer pointers in advance to avoid undefined behavior later.
That is not sufficient, though, to get correct operation of handle_cache().
The function replays a conflicted merge to extract the part inside the

Consequently, the buffers for later stages that would be present in the
