This test is pretty old and did not follow some of our more
modern best practices. In particular:
1. It chdir'd all over the place, leaving later tests to
deal with the fallout. Do our chdirs in subshells
instead.
2. It did not use test_must_fail.
3. It did not use test_line_count.
4. It checked for the non-existence of a ref by looking in the
.git/refs directory (since we pack refs during clone
these days, this will always be succeed, making the
test useless).
Note that one call to "-e .git/refs/..." remains,
because it is checking for the existence of a symbolic
ref, not a ref itself.

When a submodule repository uses alternate object store mechanism, some
commands that were started from the superproject did not notice it and
failed with "No such object" errors. The subcommands of "git submodule"
command that recursed into the submodule in a separate process were OK;
only the ones that cheated and peeked directly into the submodule's
repository from the primary process were affected.

When adding the information from a tag, put an empty line between the
message of the tag and the commented-out signature verification
information.
At least for the kernel workflow, I often end up re-formatting the message
that people send me in the tag data. In that situation, putting the tag
message and the tag signature verification back-to-back then means that
normal editor "reflow parapgraph" command will get confused and think that
the signature is a continuation of the last message paragraph.
So I always end up having to first add an empty line, and then go back and
reflow the last paragraph. Let's just do it in git directly.
The extra vertical space also makes the verification visually stand out
more from the user-supplied message, so it looks a bit more readable to me
too, but that may be just an odd personal preference.

From the FILES section of the git-config(1) manual:
$GIT_DIR/config::
Repository specific configuration file. (The filename is
of course relative to the repository root, not the working
directory.)
That's confusing because $GIT_DIR really is relative to the working
directory.
$ GIT_DIR=.git GIT_EDITOR='pwd; echo editing'
$ export GIT_DIR GIT_EDITOR
$ git config --edit --local
/home/jrn/src/git/Documentation
editing .git/config
It turns out that the comment is a remnant from older days when the
heading said ".git/config" (which is indeed relative to the top of the
worktree).
It was only when the heading was changed to refer more precisely to
<git dir>/config (see v1.5.3.2~18, AsciiDoc tweak to avoid leading
dot, 2007-09-14) that the parenthesis stopped making sense. Remove
it.

Callers who ask for ERROR_ON_NO_NAME are not so much
concerned that the name will be blank (because, after all,
we will fall back to using the username), but rather it is a
check to make sure that low-quality identities do not end up
in things like commit messages or emails (whereas it is OK
for them to end up in things like reflogs).
When future commits add more quality checks on the identity,
each of these callers would want to use those checks, too.
Rather than modify each of them later to add a new flag,
let's refactor the flag.

Before commit 43ae9f4, we generated the tail of a message id
by calling git_committer_info and parsing the email out of
the result. 43ae9f4 changed to use ident_default_email
directly, so we didn't have to bother with parsing. As a
side effect, it meant we no longer used GIT_COMMITTER_EMAIL
at all.
In general, this is probably reasonable behavior. Either the
default email is sane on your system, or you are using
user.email to provide something sane. The exception is if
you rely on GIT_COMMITTER_EMAIL being set all the time to
override the bogus generated email.
This is unlikely to match anybody's real-life setup, but we
do use it in the test environment. And furthermore, it's
what we have always done, and the change in 43ae9f4 was
about cleaning up, not fixing any bug; we should be
conservative and keep the behavior identical.

Most callers want to see all of "$name <$email> $date", but
a few want only limited parts, omitting the date, or even
the name. We already have IDENT_NO_DATE to handle the date
part, but there's not a good option for getting just the
email. Callers have to done one of:
1. Call ident_default_email; this does not respect
environment variables, nor does it promise to trim
whitespace or other crud from the result.
2. Call git_{committer,author}_info; this returns the name
and email, leaving the caller to parse out the wanted
bits.
This patch adds IDENT_NO_NAME; it stops short of adding
IDENT_NO_EMAIL, as no callers want it (nor are likely to),
and it complicates the error handling of the function.
When no name is requested, the angle brackets (<>) around
the email address are also omitted.

As a short-hand, we extract this flag into the local
variable "name_addr_only". It's more accurate to simply
negate this and refer to it as "want_date", which will be
less confusing when we add more NO_* flags.
While we're touching this part of the code, let's move the
call to ident_default_date() only when we are actually going
to use it, not when we have NO_DATE set, or when we get a
date from the environment.

There's on point in printing the name, since it is by
definition the empty string if we have reached this code
path. Instead, let's be more clear that we are complaining
about the empty name, but still show the email address that
it is attached to (since that may provide some context to
the user).

The old code allowed many references to be efficiently added to a
single directory, because it just appended the references to the
containing directory unsorted without doing any searching (and
therefore without requiring any intermediate sorting). But the old
code was inefficient when a large number of subdirectories were added
to a directory, because the directory always had to be searched to see
if the new subdirectory already existed, and this search required the
directory to be sorted first. The same was repeated for every new
subdirectory, so the time scaled like O(N^2), where N is the number of
subdirectories within a single directory.
In practice, references are often added to the ref_cache in
lexicographic order, for example when reading the packed-refs file.
So build some intelligence into add_entry_to_dir() to optimize for the
case of references and/or subdirectories being added in lexicographic
order: if the existing entries were already sorted, and the new entry
comes after the last existing entry, then adjust ref_dir::sorted to
reflect the fact that the ref_dir is still sorted.
Thanks to Peff for pointing out the performance regression that
inspired this change.

If stderr isn't a tty, we shouldn't be printing incremental progress
messages. In particular, this affects 'git checkout -f . >&logfile'
unless you provided -q. And git-new-workdir has no way to provide -q.
It would probably be better to have progress.c check isatty(2) all the time,
but that wouldn't allow things like 'git push --progress' to force progress
reporting to on, so I won't try to solve the general case right now.

careful here than usual, because we know we are building
only on OS X. But it's only polite to at least respect the

earlier.
While we're at it, let's update our definitions and rules to

Import the latest 32-bit implementation of count_masked_bytes() from
Linux (arch/x86/include/asm/word-at-a-time.h). It's shorter and avoids
overflows and negative numbers.
This fixes test failures on 32-bit, where negative partial results had
been shifted right using the "wrong" method (logical shift right instead
of arithmetic short right). The compiler is free to chose the method,
so it was only wrong in the sense that it didn't work as intended by us.
