$GIT_DIR returned by get_git_dir() is normalized, with all symlinks
resolved (see setup_work_tree function). In order to match paths (or
patterns) against $GIT_DIR char-by-char, they have to be normalized
too. There is a note in config.txt about this, that the user need to
resolve symlinks by themselves if needed.
The problem is, we allow certain path expansion, '~/' and './', for
convenience and can't ask the user to resolve symlinks in these
expansions. Make sure the expanded paths have all symlinks resolved.
PS. The strbuf_realpath(&text, get_git_dir(), 1) is still needed because
get_git_dir() may return relative path.

Sometimes a set of repositories want to share configuration settings
among themselves that are distinct from other such sets of repositories.
A user may work on two projects, each of which have multiple
repositories, and use one user.email for one project while using another
for the other.
Setting $GIT_DIR/.config works, but if the penalty of forgetting to
update $GIT_DIR/.config is high (especially when you end up cloning
often), it may not be the best way to go. Having the settings in
~/.gitconfig, which would work for just one set of repositories, would
not well in such a situation. Having separate ${HOME}s may add more
problems than it solves.
Extend the include.path mechanism that lets a config file include
another config file, so that the inclusion can be done only when some
conditions hold. Then ~/.gitconfig can say "include config-project-A
only when working on project-A" for each project A the user works on.
In this patch, the only supported grouping is based on $GIT_DIR (in
absolute path), so you would need to group repositories by directory, or
something like that to take advantage of it.
We already have include.path for unconditional includes. This patch goes
with includeIf.<condition>.path to make it clearer that a condition is
required. The new config has the same backward compatibility approach as
include.path: older git versions that don't understand includeIf will
simply ignore them.

When "git p4" imports changelist that removes paths, it failed to
convert pathnames when the p4 used encoding different from the one
used on the Git side. This has been corrected.

In a9e38359e3 we taught git-p4 a way to re-encode path names from what
was used in Perforce to UTF-8. This path re-encoding worked properly for
"added" paths. "Removed" paths were not re-encoded and therefore
different from the "added" paths. Consequently, these files were not
removed in a git-p4 cloned Git repository because the path names did not
match.
Fix this by moving the re-encoding to a place that affects "added" and
"removed" paths. Add a test to demonstrate the issue.

The push-options given via the "--push-options" option were not
passed through to external remote helpers such as "smart HTTP" that
are invoked via the transport helper.

When using non-builtin protocols relying on a transport helper
(such as http), push options are not propagated to the helper.
The user could ask for push options and a push would seemingly succeed,
but the push options would never be transported to the server,
misleading the users expectation.
Fix this by propagating the push options to the transport helper.
This is only addressing the first issue of
(1) the helper protocol does not propagate push-option
(2) the http helper is not prepared to handle push-option
Once we fix (2), the http transport helper can make use of push options
as well, but that happens as a follow up. (1) is a bug fix, whereas (2)
is a feature, which is why we only do (1) here.

"git log --graph" did not work well with "--name-only", even though
other forms of "diff" output were handled correctly.

If you run "git log --graph --name-only", the pathnames are
not indented to go along with their matching commits (unlike
all of the other diff formats). We need to output the line
prefix for each item before writing it.
The tests cover both --name-status and --name-only. The
former actually gets this right already, because it builds
on the --raw format functions. It's only --name-only which
uses its own code (and this fix mirrors the code in
diff_flush_raw()).
Note that the tests don't follow our usual style of setting
up the "expect" output inside the test block. This matches
the surrounding style, but more importantly it is easier to
read: we don't have to worry about embedded single-quotes,
and the leading indentation is more obvious.

The default behavior of update-ref to create reflogs differs in
repositories with worktree and bare ones. The existing tests cover only
the behavior of repositories with worktree.
This commit adds tests that assert the correct behavior in bare
repositories for update-ref. Two cases are covered:
- If core.logAllRefUpdates is not set, no reflogs should be created
- If core.logAllRefUpdates is true, reflogs should be created

When core.logallrefupdates is true, we only create a new reflog for refs
that are under certain well-known hierarchies. The reason is that we
know that some hierarchies (like refs/tags) are not meant to change, and
that unknown hierarchies might not want reflogs at all (e.g., a
hypothetical refs/foo might be meant to change often and drop old
history immediately).
However, sometimes it is useful to override this decision and simply log
for all refs, because the safety and audit trail is more important than
the performance implications of keeping the log around.
This patch introduces a new "always" mode for the core.logallrefupdates
option which will log updates to everything under refs/, regardless
where in the hierarchy it is (we still will not log things like
ORIG_HEAD and FETCH_HEAD, which are known to be transient).

This patch automates the process of determining which tests failed
previously and re-running them.
While developing patch series, it is a good practice to run the test
suite from time to time, just to make sure that obvious bugs are caught
early. With complex patch series, it is common to run `make -j15 -k
test`, i.e. run the tests in parallel and *not* stop at the first
failing test but continue. This has the advantage of identifying
possibly multiple problems in one big test run.
It is particularly important to reduce the turn-around time thusly on
Windows, where the test suite spends 45 minutes on the computer on which
this patch was developed.
It is the most convenient way to determine which tests failed after
running the entire test suite, in parallel, to look for left-over "trash
directory.t*" subdirectories in the t/ subdirectory. However, those
directories might live outside t/ when overridden using the
--root=<directory> option, to which the Makefile has no access. The next
best method is to grep explicitly for failed tests in the test-results/
directory, which the Makefile *can* access.
Please note that the often-recommended `prove` tool requires Perl, and
that opens a whole new can of worms on Windows. As no native Windows Perl
comes with Subversion bindings, we have to use a Perl in Git for Windows
that uses the POSIX emulation layer named MSYS2 (which is a portable
version of Cygwin). When using this emulation layer under stress, e.g.
when running massively-parallel tests, unexplicable crashes occur quite
frequently, and instead of having a solution to the original problem, the
developer now has an additional, quite huge problem. For that reason, this
developer rejected `prove` as a solution and went with this patch instead.

The user can specify a custom update method that is run when
"submodule update" updates an already checked out submodule. This
was ignored when checking the submodule out for the first time and
we instead always just checked out the commit that is bound to the
path in the superproject's index.

In 1b4735d9f3 (submodule: no [--merge|--rebase] when newly cloned,
2011-02-17), all actions were defaulted to checkout for populating
a submodule initially, because merging or rebasing makes no sense
in that situation.
Other commands however do make sense, such as the custom command
that was added later (6cb5728c43, submodule update: allow custom
command to update submodule working tree, 2013-07-03).
I am unsure about the "none" command, as I can see an initial
checkout there as a useful thing. On the other hand going strictly
by our own documentation, we should do nothing in case of "none"
as well, because the user asked for it.

When a submodule "A", which has another submodule "B" nested within

Consider having a submodule 'sub' and a nested submodule at 'sub/nested'.
When nested is already absorbed into sub, but sub is not absorbed into
its superproject, then we need to fixup the gitfile and core.worktree
setting for 'nested' when absorbing 'sub', but we do not need to move
its git dir around.
Previously 'nested's gitfile contained "gitdir: ../.git/modules/nested";
it has to be corrected to "gitdir: ../../.git/modules/sub1/modules/nested".
An alternative I considered to do this work lazily, i.e. when resolving
"../.git/modules/nested", we would notice the ".git" being a gitfile
linking to another path. That seemed to be robuster by design, but harder
to get the implementation right. Maybe we have to do that anyway once we
try to have submodules and worktrees working nicely together, but for now
just produce 'correct' (i.e. direct) pointers.

In the future we want to support working tree operations within submodules,
e.g. "git checkout --recurse-submodules", which will update the submodule
to the commit as recorded in its superproject. In the submodule the
unpack-tree operation is carried out as usual, but the reporting to the
user needs to prefix any path with the superproject. The mechanism for
this is the super-prefix. (see 74866d757, git: make super-prefix option)
Add support for the super-prefix option for commands that unpack trees
by wrapping any path output in unpacking trees in the newly introduced
super_prefixed function. This new function prefixes any path with the
super-prefix if there is one. Assuming the submodule case doesn't happen
in the majority of the cases, we'd want to have a fast behavior for no
super prefix, i.e. no reallocation/copying, but just returning path.
Another aspect of introducing the `super_prefixed` function is to consider
who owns the memory and if this is the right place where the path gets
modified. As the super prefix ought to change the output behavior only and
not the actual unpack tree part, it is fine to be that late in the line.
As we get passed in 'const char *path', we cannot change the path itself,
which means in case of a super prefix we have to copy over the path.
We need two static buffers in that function as the error messages
contain at most two paths.
For testing purposes enable it in read-tree, which has no output
of paths other than an unpack-trees.c. These are all converted in
this patch.

Some people feel the default set of colors used by "git log --graph"
rather limiting. A mechanism to customize the set of colors has
been introduced.

Prior to c2f41bf52 (color.c: fix color_parse_mem() with
value_len == 0, 2017-01-19), the empty string was
interpreted as a color "reset". This was an accidental
outcome, and that commit turned it into an error.
However, scripts may pass the empty string as a default
value to "git config --get-color" to disable color when the
value is not defined. The git-add--interactive script does
this. As a result, the script is unusable since c2f41bf52
unless you have color.diff.plain defined (if it is defined,
then we don't parse the empty default at all).
Our test scripts didn't notice the recent breakage because
they run without a terminal, and thus without color. They
never hit this code path at all. And nobody noticed the
original buggy "reset" behavior, because it was effectively
a noop.
Let's fix the code to have an empty color name produce an
empty sequence of color codes. The tests need a few fixups:
- we'll add a new test in t4026 to cover this case. But
note that we need to tweak the color() helper. While
we're there, let's factor out the literal ANSI ESC
character. Otherwise it makes the diff quite hard to
read.
- we'll add a basic sanity-check in t4026 that "git add
-p" works at all when color is enabled. That would have
caught this bug, as well as any others that are specific
to the color code paths.
- 73c727d69 (log --graph: customize the graph lines with
config log.graphColors, 2017-01-19) added a test to
t4202 that checks some "invalid" graph color config.
Since ",, blue" before yielded only "blue" as valid, and
now yields "empty, empty, blue", we don't match the
expected output.
One way to fix this would be to change the expectation
to the empty color strings. But that makes the test much
less interesting, since we show only two graph lines,
both of which would be colorless.
Since the empty-string case is now covered by t4026,
let's remove them entirely here. They're just in the way
of the primary thing the test is supposed to be
checking.

If you have a 256 colors terminal (or one with true color support), then
the predefined 12 colors seem limited. On the other hand, you don't want
to draw graph lines with every single color in this mode because the two
colors could look extremely similar. This option allows you to hand pick
the colors you want.
Even with standard terminal, if your background color is neither black
or white, then the graph line may match your background and become
hidden. You can exclude your background color (or simply the colors you
hate) with this.

The "init creates a new deep directory (umask vs. shared)" test expects
the permissions of newly created files to be based on the umask, which
fails if a default ACL is inherited from the working tree for git. So
attempt to remove a default ACL if there is one. Same idea as
8ed0a740dd42bd0724aebed6e3b07c4ea2a2d5e8. (I guess I'm the only one who
ever runs the test suite with a default ACL set.)

Eric Wong reported that while FreeBSD has a /usr/bin/unzip, it uses
different semantics from those that are needed by Git's tests: When
passing the -a option to Info-Zip, it heeds the text attribute of the
.zip file's central directory, while FreeBSD's unzip ignores that
attribute.
The common work-around is to install Info-Zip on FreeBSD, into
/usr/local/bin/.

"git submodule add" used to be confused and refused to add a

Currently the force flag in `git submodule add` takes care of possibly
ignored files or when a name collision occurs.
However there is another situation where submodule add comes in handy:
When you already have a gitlink recorded, but no configuration was
done (i.e. no .gitmodules file nor any entry in .git/config) and you
want to generate these config entries. For this situation allow
`git submodule add` to proceed if there is already a submodule at the
given path in the index.

The loose objects are created with mode 0444. That doesn't
prevent them being overwritten by rename(), but some
versions of "mv" will be extra careful and prompt the user,
even without "-i".
Reportedly macOS does this, at least in the Travis builds.
The prompt reads from /dev/null, defaulting to "no", and the
object isn't moved. Then to make matters even more
interesting, it still returns "0" and the rest of the test
proceeds, but with a broken setup.
We can work around it by using "mv -f" to override the
prompt. This should work as it's already used in t5504 for
the same purpose.

Since fsck tries to continue as much as it can after seeing
an error, we still do the reachability check even if some
heads we were given on the command-line are bogus. But if
_none_ of the heads is is valid, we fallback to checking all
refs and the index, which is not what the user asked for at
all.
Instead of checking "heads", the number of successful heads
we got, check "argc" (which we know only has non-options in
it, because parse_options removed the others).

Instead of checking reachability from the refs, you can ask
fsck to check from a particular set of heads. However, the
error checking here is quite lax. In particular:
1. It claims lookup_object() will report an error, which
is not true. It only does a hash lookup, and the user
has no clue that their argument was skipped.
2. When either the name or sha1 cannot be resolved, we
continue to exit with a successful error code, even
though we didn't check what the user asked us to.
This patch fixes both of these cases.

Normally fsck makes a pass over all objects to check their
integrity, and then follows up with a reachability check to
make sure we have all of the referenced objects (and to know
which ones are dangling). The latter checks for the HAS_OBJ
flag in obj->flags to see if we found the object in the
first pass.
Commit 02976bf85 (fsck: introduce `git fsck --connectivity-only`,
2015-06-22) taught fsck to skip the initial pass, and to
fallback to has_sha1_file() instead of the HAS_OBJ check.
However, it converted only one HAS_OBJ check to use
has_sha1_file(). But there are many other places in
builtin/fsck.c that assume that the flag is set (or that
lookup_object() will return an object at all). This leads to
several bugs with --connectivity-only:
1. mark_object() will not queue objects for examination,
so recursively following links from commits to trees,
etc, did nothing. I.e., we were checking the
reachability of hardly anything at all.
2. When a set of heads is given on the command-line, we
use lookup_object() to see if they exist. But without
the initial pass, we assume nothing exists.
3. When loading reflog entries, we do a similar
lookup_object() check, and complain that the reflog is
broken if the object doesn't exist in our hash.
So in short, --connectivity-only is broken pretty badly, and
will claim that your repository is fine when it's not.
Presumably nobody noticed for a few reasons.
One is that the embedded test does not actually test the
recursive nature of the reachability check. All of the
missing objects are still in the index, and we directly
check items from the index. This patch modifies the test to
delete the index, which shows off breakage (1).
Another is that --connectivity-only just skips the initial
pass for loose objects. So on a real repository, the packed
objects were still checked correctly. But on the flipside,
it means that "git fsck --connectivity-only" still checks
the sha1 of all of the packed objects, nullifying its
original purpose of being a faster git-fsck.
And of course the final problem is that the bug only shows
up when there _is_ corruption, which is rare. So anybody
running "git fsck --connectivity-only" proactively would
assume it was being thorough, when it was not.
One possibility for fixing this is to find all of the spots
that rely on HAS_OBJ and tweak them for the connectivity-only
case. But besides the risk that we might miss a spot (and I
found three already, corresponding to the three bugs above),
there are other parts of fsck that _can't_ work without a
full list of objects. E.g., the list of dangling objects.
Instead, let's make the connectivity-only case look more
like the normal case. Rather than skip the initial pass
completely, we'll do an abbreviated one that sets up the
HAS_OBJ flag for each object, without actually loading the
object data.
That's simple and fast, and we don't have to care about the
connectivity_only flag in the rest of the code at all.
While we're at it, let's make sure we treat loose and packed
objects the same (i.e., setting up dummy objects for both
and skipping the actual sha1 check). That makes the
connectivity-only check actually fast on a real repo (40
seconds versus 180 seconds on my copy of linux.git).

After checking connectivity, fsck looks through the list of
any objects we've seen mentioned, and reports unreachable
and un-"used" ones as dangling. However, it skips any object
which is not marked as "parsed", as that is an object that
we _don't_ have (but that somebody mentioned).
Since 6e454b9a3 (clear parsed flag when we free tree
buffers, 2013-06-05), that flag can't be relied on, and the
correct method is to check the HAS_OBJ flag. The cleanup in
that commit missed this callsite, though. As a result, we
would generally fail to report dangling trees.
We never noticed because there were no tests in this area
(for trees or otherwise). Let's add some.

This test creates a multi-level set of trees, but its
cleanup routine only removes the top-level tree. After the
test finishes, the inner tree and the blob it points to
remain, making the inner tree dangling.
A later test ("cleaned up") verifies that we've removed any
cruft and "git fsck" output is clean. This passes only
because of a bug in git-fsck which fails to notice dangling
trees.
In preparation for fixing the bug, let's teach this earlier
test to clean up after itself correctly. We have to remove
the inner tree (and therefore the blob, too, which becomes
dangling after removing that tree).
Since the setup code happens inside a subshell, we can't
just set a variable for each object. However, we can stuff
all of the sha1s into the $T output variable, which is not
used for anything except cleanup.

Rewrite a scripted porcelain "git difftool" in C.
* js/difftool-builtin:
difftool: hack around -Wzero-length-format warning
difftool: retire the scripted version
difftool: implement the functionality in the builtin
difftool: add a skeleton for the upcoming builtin

It served its purpose, but now we have a builtin difftool. Time for the
Perl script to enjoy Florida.

This adds a builtin difftool that still falls back to the legacy Perl
version, which has been renamed to `legacy-difftool`.
The idea is that the new, experimental, builtin difftool immediately hands
off to the legacy difftool for now, unless the config variable
difftool.useBuiltin is set to true.
This feature flag will be used in the upcoming Git for Windows v2.11.0
release, to allow early testers to opt-in to use the builtin difftool and
flesh out any bugs.
