Usually we do not pass an empty string to the function hash_name()
because we almost always ask for hash values for a path that is a
candidate to be added to the index. However, check-ignore (and most
likely check-attr, but I didn't check) apparently has a callchain
to ask the hash value for an empty path when it was given a "." from
the top-level directory to ask "Is the path . excluded by default?"
Make sure that hash_name() does not overrun the end of the given
pathname even when it is empty.
Remove a sweep-the-issue-under-the-rug conditional in check-ignore
that avoided to pass an empty string to the callchain while at it.
It is a valid question to ask for check-ignore if the top-level is
set to be ignored by default, even though the answer is most likely
no, if only because there is currently no way to specify such an
entry in the .gitignore file. But it is an unusual thing to ask and
it is not worth optimizing for it by special casing at the top level
of the call chain.

If you run "git log --grep=foo", we will run your regex on
the literal bytes of the commit message. This can provide
confusing results if the commit message is not in the same
encoding as your grep expression (or worse, you have commits
in multiple encodings, in which case your regex would need
to be written to match either encoding). On top of this, we
might also be grepping in the commit's notes, which are
already re-encoded, potentially leading to grepping in a
buffer with mixed encodings concatenated. This is insanity,
but most people never noticed, because their terminal and
their commit encodings all match.
Instead, let's massage the to-be-grepped commit into a
standardized encoding. There is not much point in adding a
flag for "this is the encoding I expect my grep pattern to
match"; the only sane choice is for it to use the log output
encoding. That is presumably what the user's terminal is
using, and it means that the patterns found by the grep will
match the output produced by git.
As a bonus, this fixes a potential segfault in commit_match
when commit->buffer is NULL, as we now build on logmsg_reencode,
which handles reading the commit buffer from disk if
necessary. The segfault can be triggered with:
git commit -m 'text1' --allow-empty
git commit -m 'text2' --allow-empty
git log --graph --no-walk --grep 'text2'
which arguably does not make any sense (--graph inherently
wants a connected history, and by --no-walk the command line
is telling us to show discrete points in history without
connectivity), and we probably should forbid the
combination, but that is a separate issue.

A repository may have refs that are only used for its internal
bookkeeping purposes that should not be exposed to the others that
come over the network.
Teach upload-pack to omit some refs from its initial advertisement
by paying attention to the uploadpack.hiderefs multi-valued
configuration variable. Do the same to receive-pack via the
receive.hiderefs variable. As a convenient short-hand, allow using
transfer.hiderefs to set the value to both of these variables.
Any ref that is under the hierarchies listed on the value of these
variable is excluded from responses to requests made by "ls-remote",
"fetch", etc. (for upload-pack) and "push" (for receive-pack).
Because these hidden refs do not count as OUR_REF, an attempt to
fetch objects at the tip of them will be rejected, and because these
refs do not get advertised, "git push :" will not see local branches
that have the same name as them as "matching" ones to be sent.
An attempt to update/delete these hidden refs with an explicit
refspec, e.g. "git push origin :refs/hidden/22", is rejected. This
is not a new restriction. To the pusher, it would appear that there
is no such ref, so its push request will conclude with "Now that I
sent you all the data, it is time for you to update the refs. I saw
that the ref did not exist when I started pushing, and I want the
result to point at this commit". The receiving end will apply the
compare-and-swap rule to this request and rejects the push with
"Well, your update request conflicts with somebody else; I see there
is such a ref.", which is the right thing to do. Otherwise a push to
a hidden ref will always be "the last one wins", which is not a good
default.

The typical use-case is starting a rebase, do something else, come
back the day after, run "git status" or make a new commit and wonder
what in the world's going on. Which branch is being rebased is
probably the most useful tidbit to help, but the target may help
too.
Ideally, I would have loved to see "rebasing master on
origin/master", but the target ref name is not stored during rebase,
so this patch writes "rebasing master on a78c8c98b" as a
half-measure to remind future users of that potential improvement.

Earlier, a230949 (am --rebasing: get patch body from commit, not
from mailbox, 2012-06-26) learned to regenerate patch body from the
commit object while rebasing, instead of reading from the rebase-am
front-end. While doing so, it used "git diff-tree" but without
giving it the "--full-index" option.
This does not matter for in-repository objects; during rebasing, any
abbreviated object name should uniquely identify them.
But we may be rebasing a commit that contains a change to a gitlink,
in which case we usually should not have the object (it names a
commit in the submodule). A full object name is necessary to later
reconstruct a fake ancestor index for them.

Currently, a branch filter like `--contains`, `--merged`, or
`--no-merged` is ignored when we are not in listing mode.
For example:
git branch --contains=foo bar
will create the branch "bar" from the current HEAD, ignoring
the `--contains` argument entirely. This is not very
helpful. There are two reasonable behaviors for git here:
1. Flag an error; the arguments do not make sense.
2. Implicitly go into `--list` mode
This patch chooses the latter, as it is more convenient, and
there should not be any ambiguity with attempting to create
a branch; using `--contains` and not wanting to list is
nonsensical.
That leaves the case where an explicit modification option
like `-d` is given. We already catch the case where
`--list` is given alongside `-d` and flag an error. With
this patch, we will also catch the use of `--contains` and
other filter options alongside `-d`.

This test does a commit that is a pure mode change, submits
it to p4 but causes the submit to fail. It verifies that
the state in p4 as well as the client directory are both
unmodified after the failed submit.
On cygwin, "chmod +x" does nothing, so use the test_chmod
function to modify the index directly too.
Also on cygwin, the executable bit cannot be seen in the
filesystem, so avoid that part of the test. The checks of
p4 state are still valid, though.

There are some old versions of p4, compiled for cygwin, that
treat read-only files differently.
Normally, a file that is not open is read-only, meaning that
"test -w" on the file is false. This works on unix, and it works
on windows using the NT version of p4. The cygwin version
of p4, though, changes the permissions, but does not set the
windows read-only attribute, so "test -w" returns false.
Notice this oddity and make the tests work, even on cygiwn.
