nedmalloc: work around overzealous GCC 6 warning
With GCC 6, the strdup() function is declared with the "nonnull"
attribute, stating that it is not allowed to pass a NULL value as
parameter.
In nedmalloc()'s reimplementation of strdup(), Postel's Law is heeded
and NULL parameters are handled gracefully. GCC 6 complains about that
now because it thinks that NULL cannot be passed to strdup() anyway.
Because the callers in this project of strdup() must be prepared to
call any implementation of strdup() supplied by the platform, so it
is pointless to pretend that it is OK to call it with NULL.
Remove the conditional based on NULL-ness of the input; this
squelches the warning. Check the return value of malloc() instead
to make sure we actually got the memory to write to.

t7063: work around FreeBSD's lazy mtime update feature
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
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.

t4130: work around Windows limitation
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.

am: reset cached ident date for each patch
When we compute the date to go in author/committer lines of
commits, or tagger lines of tags, we get the current date
once and then cache it for the rest of the program. This is
a good thing in some cases, like "git commit", because it
means we do not racily assign different times to the
author/committer fields of a single commit object.
But as more programs start to make many commits in a single
process (e.g., the recently builtin "git am"), it means that
you'll get long strings of commits with identical committer
timestamps (whereas before, we invoked "git commit" many
times and got true timestamps).
This patch addresses it by letting callers reset the cached
time, which means they'll get a fresh time on their next
call to git_committer_info() or git_author_info(). The first
caller to do so is "git am", which resets the time for each
patch it applies.
It would be nice if we could just do this automatically
before filling in the ident fields of commit and tag
objects. Unfortunately, it's hard to know where a particular
logical operation begins and ends.
For instance, if commit_tree_extended() were to call
reset_ident_date() before getting the committer/author
ident, that doesn't quite work; sometimes the author info is
passed in to us as a parameter, and it may or may not have
come from a previous call to ident_default_date(). So in
those cases, we lose the property that the committer and the
author timestamp always match.
You could similarly put a date-reset at the end of
commit_tree_extended(). That actually works in the current
code base, but it's fragile. It makes the assumption that
after commit_tree_extended() finishes, the caller has no
other operations that would logically want to fall into the
same timestamp.
So instead we provide the tool to easily do the reset, and
let the high-level callers use it to annotate their own
logical operations.
There's no automated test, because it would be inherently
racy (it depends on whether the program takes multiple
seconds to run). But you can see the effect with something
like:
# make a fake 100-patch series
top=$(git rev-parse HEAD)
bottom=$(git rev-list --first-parent -100 HEAD | tail -n 1)
git log --format=email --reverse --first-parent \
--binary -m -p $bottom..$top >patch
# now apply it; this presumably takes multiple seconds
git checkout --detach $bottom
git am <patch
# now count the number of distinct committer times;
# prior to this patch, there would only be one, but
# now we'd typically see several.

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
need to" style.

t4205: drop top-level &&-chaining
The test currently does something like:
do_one() &&
do_two() &&
test_expect_success ...
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.
It _could_ go into the following test block, but since the
result in this case is used by multiple tests, it's more
clear to mark it explicitly as a distinct setup step.

subtree: fix "git subtree split --rejoin"
"git merge" in v2.9 prevents merging unrelated histories.
"git subtree split --rejoin" creates unrelated histories when
creating a split repo from a raw sub-directory that did not
originate from an invocation of "git subtree add".
Restore the original behavior by passing --allow-unrelated-histories
when merging subtrees. This ensures that the synthetic history
created by "git subtree split" can be merged.
Add a test to ensure that this feature works as advertised.

grep: further simplify setting the pattern type
When c5c31d33 (grep: move pattern-type bits support to top-level
grep.[ch], 2012-10-03) introduced grep_commit_pattern_type() helper
function, the intention was to allow the users of grep API to having
to fiddle only with .pattern_type_option (which can be set to "fixed",
"basic", "extended", and "pcre"), and then immediately before compiling
the pattern strings for use, call grep_commit_pattern_type() to have
it prepare various bits in the grep_opt structure (like .fixed,
.regflags, etc.).
However, grep_set_pattern_type_option() helper function the grep API
internally uses were left as an external function by mistake. This
function shouldn't have been made callable by the users of the API.
Later when the grep API was used in revision traversal machinery,
the caller then mistakenly started calling the function around 34a4ae55 (log --grep: use the same helper to set -E/-F options as
"git grep", 2012-10-03), instead of setting the .pattern_type_option
field and letting the grep_commit_pattern_type() to take care of the
details.
This caused an unnecessary bug that made a configured
grep.patternType take precedence over the command line options
(e.g. --basic-regexp, --fixed-strings) in "git log" family of
commands.

Documentation: pack-protocol correct NAK response
In the transport protocol we use NAK to signal the non existence of a
common base, so fix the documentation. This helps readers of the document,

As NACK is used in git archive and upload-archive, this is easy to get
wrong.

diff: do not reuse worktree files that need "clean" conversion
When accessing a blob for a diff, we may try to reuse file
contents in the working tree, under the theory that it is
faster to mmap those file contents than it would be to
extract the content from the object database.
When we have to filter those contents, though, that
assumption does not hold. Even for our internal conversions
like CRLF, we have to allocate and fill a new buffer anyway.
But much worse, for external clean filters we have to exec
an arbitrary script, and we have no idea how expensive it
may be to run.
So let's skip this optimization when conversion into git's
"clean" form is required. This applies whenever the
"want_file" flag is false. When it's true, the caller
actually wants the smudged worktree contents, which the
reused file by definition already has (in fact, this is a
key optimization going the other direction, since reusing
the worktree file there lets us skip smudge filters).

The previous method simply used the UNIX timestamp of when the binary was

This patch aims to align the label for this binary with the Git version

of the binary as it can be mapped to a particular revision or release of
Git itself. For example:

t5541: fix url scrubbing test when GPG is not set
When the GPG prereq is not set, we do not run test 34. That
test changes the directory of the test script as a side
effect (something we usually frown on, but which matches the
style of the rest of this script). When test 35 (the
url-scrubbing test) runs, it expects to be in the directory
from test 34. If it's not, the test fails; we are in a
different sub-repo, our test-commit is built on a different
history, and the push becomes a non-fast-forward.
We can fix this by unconditionally moving to the directory
we expect (again, against our usual style but matching how
the rest of the script operates).
As an additional protection, let's also switch from "make a
new commit and push to master" to just "push to a new
branch". We don't care about the branch name; we just want
_some_ ref update to trigger the status output. Pushing to a
new branch is less likely to run into problems with
force-updates, changing the checked-out branch, etc.
