The newly-added test case wants to commit a file "c.t" (note the lower
case) when a previous test case already committed a file "C.t". This
confuses Git to the point that it thinks "c.t" was not staged when "git
add c.t" was called.
Simply make the naming of the test commits consistent with the previous
test cases: use upper-case, and advance in the alphabet.
This came up in local work to rebase the Windows-specific patches to the
current `next` branch. An identical fix was suggested by John Keeping.

Let's start with the commit message of [1] from freebsd.git [2]
Sync timestamp changes for inodes of special files to disk as late
as possible (when the inode is reclaimed). Temporarily only do
this if option UFS_LAZYMOD configured and softupdates aren't
enabled. UFS_LAZYMOD is intentionally left out of
/sys/conf/options.
This is mainly to avoid almost useless disk i/o on battery powered
machines. It's silly to write to disk (on the next sync or when
the inode becomes inactive) just because someone hit a key or
something wrote to the screen or /dev/null.
PR: 5577 [3]
The short version of that, in the context of t7063, is that when a
directory is updated, its mtime may be updated later, not
immediately. This can be shown with a simple command sequence
date; sleep 1; touch abc; rm abc; sleep 10; ls -lTd .
One would expect that the date shown in `ls` would be one second from
`date`, but it's 10 seconds later. If we put another `ls -lTd .` in
front of `sleep 10`, then the date of the last `ls` comes as
expected. The first `ls` somehow forces mtime to be updated.
t7063 is really sensitive to directory mtime. When mtime is too "new",
git code suspects racy timestamps and will not trigger the shortcut in
untracked cache, in t7063.24 and eventually be detected in t7063.27
We have two options thanks to this special FreeBSD feature:
1) Stop supporting untracked cache on FreeBSD. Skip t7063 entirely
when running on FreeBSD
2) Work around this problem (using the same 'ls' trick) and continue
to support untracked cache on FreeBSD
I initially wanted to go with 1) because I didn't know the exact
nature of this feature and feared that it would make untracked cache
work unreliably, using the cached version when it should not.
Since the behavior of this thing is clearer now. The picture is not
that bad. If this indeed happens often, untracked cache would assume
racy condition more often and _fall back_ to non-untracked cache code
paths. Which means it may be less effective, but it will not show
wrong things.
This patch goes with option 2.
PS. For those who want to look further in FreeBSD source code, this
flag is now called IN_LAZYMOD. I can see it's effective in ext2 and
ufs. zfs is not affected.

Gerrit has a "superproject subscription" feature[1], that triggers a
commit in a superproject that is subscribed to its submodules.
Conceptually this Gerrit feature can be done on the client side with
Git via (except for raciness, error handling etc):
while [ true ]; do
git -C <superproject> submodule update --remote --force
git -C <superproject> commit -a -m "Update submodules"
git -C <superproject> push
done
for each branch in the superproject. To ease the configuration in Gerrit
a special value of "." has been introduced for the submodule.<name>.branch
to mean the same branch as the superproject[2], such that you can create a
new branch on both superproject and the submodule and this feature
continues to work on that new branch.
Now we find projects in the wild with such a .gitmodules file.
The .gitmodules used in these Gerrit projects do not conform
to Gits understanding of how .gitmodules should look like.
This teaches Git to deal gracefully with this syntax as well.
The redefinition of "." does no harm to existing projects unaware of
this change, as "." is an invalid branch name in Git, so we do not
expect such projects to exist.

There is an optimization used in "git diff $treeA $treeB" to borrow

On Windows, it is already pretty expensive to try to recreate the stat()
data that Git assumes is cheap to obtain. To make things halfway decent
in performance, we even have to skip emulating the inode and to
determine the number of hard links.
This is not a huge problem, usually, as either the size or the mtime or
the ctime are tell-tale enough to say when a file has changed, and even
if not, those changes are typically made after the index file was
written, triggering a rehashing of the files' contents.
The t4130-apply-criss-cross-rename test case, however, requires the
inode to determine that files of equal size were swapped, as renaming
files does not update their mtime. Every once in a while, t4130 fails
on Windows because of this missing piece.
Equal file sizes are not crucial for the test cases, however. Hence,
generate files with different sizes so that there is some property that
the swapped files can be discovered reliably even on Windows.

When an earlier test that has prerequisite is skipped, files
used by later tests may be left in the working tree in an
unexpected state. For example, a test runs this sequence:
echo foo >xfoo1 && chmod 755 xfoo1
to create an executable file xfoo1, expecting that xfoo1
does not exist before it runs in the test sequence.
However, the absence of this file depends on "git reset
--hard" done in an earlier test, that is skipped when SANITY
prerequisite is not met, and worse yet, xfoo1 originally is
created as a symbolic link, which means the chmod does not
affect the modes of xfoo1 as this test expects.
Fix this by starting the test with "rm -f xfoo1" to make
sure the file is created from scratch, and do the same to
other similar tests.

Since the very inception of interactive-rebase in 1b1dce4
(Teach rebase an interactive mode, 2007-06-25), there has
been a preemptive check, before looking at any commits, to
see whether the user has a valid name/email combination.
This is convenient, because it means that we abort the
operation before even beginning (rather than just
complaining that we are unable to pick a particular commit).
However, it does the wrong thing when the rebase does not
actually need to generate any new commits (e.g., a
fast-forward with no commits to pick, or one where the base
stays the same, and we just pick the same commits without
rewriting anything). In this case it may complain about the
lack of ident, even though one would not be needed to
complete the operation.
This may seem like mere nit-picking, but because interactive
rebase underlies the "preserve-merges" rebase, somebody who
has set "pull.rebase" to "preserve" cannot make even a
fast-forward pull without a valid ident, as we bail before
even realizing the fast-forward nature.
This commit drops the extra ident check entirely. This means
we rely on individual commands that generate commit objects
to complain. So we will continue to notice and prevent cases
that actually do create commits, but with one important
difference: we fail while actually executing the "pick"
operations, and leave the rebase in a conflicted, half-done
state.
In some ways this is less convenient, but in some ways it is
more so; the user can then manually commit or even "git
rebase --continue" after setting up their ident (or
providing it as a one-off on the command line).

Git's pack storage does efficient (log n) lookups in a
single packfile's index, but if we have multiple packfiles,
we have to linearly search each for a given object. This
patch introduces some timing tests for cases where we have a
large number of packs, so that we can measure any
improvements we make in the following patches.
The main thing we want to time is object lookup. To do this,
we measure "git rev-list --objects --all", which does a
fairly large number of object lookups (essentially one per
object in the repository).
However, we also measure the time to do a full repack, which
is interesting for two reasons. One is that in addition to
the usual pack lookup, it has its own linear iteration over
the list of packs. And two is that because it it is the tool
one uses to go from an inefficient many-pack situation back
to a single pack, we care about its performance not only at
marginal numbers of packs, but at the extreme cases (e.g.,
if you somehow end up with 5,000 packs, it is the only way
to get back to 1 pack, so we need to make sure it performs
well).
We measure the performance of each command in three
scenarios: 1 pack, 50 packs, and 1,000 packs.
The 1-pack case is a baseline; any optimizations we do to
handle multiple packs cannot possibly perform better than
this.
The 50-pack case is as far as Git should generally allow
your repository to go, if you have auto-gc enabled with the
default settings. So this represents the maximum performance
improvement we would expect under normal circumstances.
The 1,000-pack case is hopefully rare, though I have seen it
in the wild where automatic maintenance was broken for some
time (and the repository continued to receive pushes). This
represents cases where we care less about general
performance, but want to make sure that a full repack
command does not take excessively long.

The "raw" format shows a Unix epoch timestamp, but with a

it is extra information about the time (by default, the zone
the author was in).
The documentation claims that "raw-local" does not work. It
does, but the end result is rather subtle. Let's describe it
in better detail, and test to make sure it works (namely,
the epoch time doesn't change, but the zone does).
While we are rewording the documentation in this area, let's
not use the phrase "does not work" for the remaining option,
"--date=relative". It's vague; do we accept it or not? We do
accept it, but it has no effect (which is a reasonable
outcome). We should also refer to the option not as
"--relative" (which is the historical synonym, and does not
take "-local" at all), but as "--date=relative".

Our usual style in the test scripts is to indent here
documents with tabs, and use "<<-" to strip the tabs. The
result is easier to read.
This old test script did not do so in its inception, and
further tests added onto it followed the local style. Let's
bring it in line with our usual style.
Some of the tests actually care quite a bit about
whitespace, but none of them do so at the beginning of the
line (because they use things like qz_to_tab_space to avoid
depending on the literal whitespace), so we can do a fairly
mechanical conversion.
Most of the here-docs also use interpolation, so they have
been left as "<<-EOF". In a few cases, though, where
interpolation was not in use, I've converted them to
"<<-\EOF" to match our usual "don't interpolate unless you

The test currently does something like:

We generally avoid performing actions at the top-level of
the script (outside of a test_expect block) for two reasons:
1. The test harness is not checking and reporting if they
fail.
2. Their output is not handled correctly (not hidden by
default, nor shown with "-v").
Using &&-chains seems like it should help with (1), but it
doesn't. If either of the commands fails, we simply skip
running the follow-on test entirely, and the test harness
has no idea.
We can fix this by pushing that setup into its own block.
