Just like `scalar register` starts the scheduled background maintenance,
`scalar unregister` stops it. Note that we use `git maintenance start`
in `scalar register`, but we do not use `git maintenance stop` in
`scalar unregister`: this would stop maintenance for _all_ repositories,
not just for the one we want to unregister.
The `unregister` command also removes the corresponding entry from the
`[scalar]` section in the global Git config.

Let's start implementing the `register` command. With this commit,
recommended settings are configured upon `scalar register`, and Git's
background maintenance is started.
The recommended config settings may very well change in the future. For
example, once the built-in FSMonitor is available, we will want to
enable it upon `scalar register`. For that reason, we explicitly support
running `scalar register` in an already-registered enlistment.

To test the Scalar command, create a test script in contrib/scalar/t
that is executed as `make -C contrib/scalar test`. Since Scalar has no
meaningful capabilities yet, the only test is rather simple. We will add
more tests in subsequent commits that introduce corresponding, new
functionality.
Note: This test script is intended to test `scalar` only lightly, even
after all of the functionality is implemented.
A more comprehensive functional (or: integration) test suite can be
found at https://github.com/microsoft/scalar; It is used in the workflow
https://github.com/microsoft/git/blob/HEAD/.github/workflows/scalar-functional-tests.yml
in Microsoft's Git fork. This test suite performs end-to-end tests with
a real remote repository, and is run as part of the regular CI and PR
builds in that fork.
Since those tests require some functionality supported only by
Microsoft's Git fork ("GVFS protocol"), there is no intention to port
that fuller test suite to `contrib/scalar/`.

The idea of Scalar (https://github.com/microsoft/scalar), and before
that, of VFS for Git, has always been to prove that Git _can_ scale, and
to upstream whatever strategies have been demonstrated to help.
With this patch, we start the journey from that C# project to move what
is left to Git's own `contrib/` directory, reimplementing it in pure C,
with the intention to facilitate integrating the functionality into core
Git all while maintaining backwards-compatibility for existing Scalar
users (which will be much easier when both live in the same worktree).
It has always been the plan to contribute all of the proven strategies
back to core Git.
For example, while the virtual filesystem provided by VFS for Git helped
the team developing the Windows operating system to move onto Git, while
trying to upstream it we realized that it cannot be done: getting the
virtual filesystem to work (which we only managed to implement fully on
Windows, but not on, say, macOS or Linux), and the required server-side
support for the GVFS protocol, made this not quite feasible.
The Scalar project learned from that and tackled the problem with
different tactics: instead of pretending to Git that the working
directory is fully populated, it _specifically_ teaches Git about
partial clone (which is based on VFS for Git's cache server), about
sparse checkout (which VFS for Git tried to do transparently, in the
file system layer), and regularly runs maintenance tasks to keep the
repository in a healthy state.
With partial clone, sparse checkout and `git maintenance` having been
upstreamed, there is little left that `scalar.exe` does which `git.exe`
cannot do. One such thing is that `scalar clone <url>` will
automatically set up a partial, sparse clone, and configure
known-helpful settings from the start.
So let's bring this convenience into Git's tree.
The idea here is that you can (optionally) build Scalar via
make -C contrib/scalar/
This will build the `scalar` executable and put it into the
contrib/scalar/ subdirectory.
The slightly awkward addition of the `contrib/scalar/*` bits to the
top-level `Makefile` are actually really required: we want to link to
`libgit.a`, which means that we will need to use the very same `CFLAGS`
and `LDFLAGS` as the rest of Git.
An early development version of this patch tried to replicate all the
conditional code in `contrib/scalar/Makefile` (e.g. `NO_POLL`) just like
`contrib/svn-fe/Makefile` used to do before it was retired. It turned
out to be quite the whack-a-mole game: the SHA-1-related flags, the
flags enabling/disabling `compat/poll/`, `compat/regex/`,
`compat/win32mmap.c` & friends depending on the current platform... To
put it mildly: it was a major mess.
Instead, this patch makes minimal changes to the top-level `Makefile` so
that the bits in `contrib/scalar/` can be compiled and linked, and
adds a `contrib/scalar/Makefile` that uses the top-level `Makefile` in a
most minimal way to do the actual compiling.
Note: With this commit, we only establish the infrastructure, no
Scalar functionality is implemented yet; We will do that incrementally
over the next few commits.

The C99 standard was released in January 1999, now 22 years ago. It
provides a variety of useful features, including variadic arguments for
macros, declarations after statements, designated initializers, and a
wide variety of other useful features, many of which we already use.
We'd like to take advantage of these features, but we want to be
cautious. As far as we know, all major compilers now support C99 or a
later C standard, such as C11 or C17. POSIX has required C99 support as
a requirement for the 2001 revision, so we can safely assume any POSIX
system which we are interested in supporting has C99.
Even MSVC, long a holdout against modern C, now supports both C11 and
C17 with an appropriate update. Moreover, even if people are using an
older version of MSVC on these systems, they will generally need some
implementation of the standard Unix utilities for the testsuite, and GNU
coreutils, the most common option, has required C99 since 2009.
Therefore, we can safely assume that a suitable version of GCC or clang
is available to users even if their version of MSVC is not sufficiently
capable.
Let's add a test balloon to git-compat-util.h to see if anyone is using
an older compiler. We'll add a comment telling people how to enable
this functionality on GCC and Clang, even though modern versions of both
will automatically do the right thing, and ask people still experiencing
a problem to report that to us on the list.
Note that C89 compilers don't provide the __STDC_VERSION__ macro, so we
use a well-known hack of using "- 0". On compilers with this macro, it
doesn't change the value, and on C89 compilers, the macro will be
replaced with nothing, and our value will be 0.
For sparse, we explicitly request the gnu99 style because we've
traditionally taken advantage of some GCC- and clang-specific extensions
when available and we'd like to retain the ability to do that. sparse
also defaults to C89 without it, so things will fail for us if we don't.
Update the cmake configuration to require C11 for MSVC. We do this
because this will make MSVC to use C11, since it does not explicitly
support C99. We do this with a compiler options because setting the
C_STANDARD option does not work in our CI on MSVC and at the moment, we
don't want to require C11 for Unix compilers.
In the Makefile, don't set any compiler flags for the compiler itself,
since on some systems, such as FreeBSD, we actually need C11, and asking
for C99 causes things to fail to compile. The error message should make
it obvious what's going wrong and allow a user to set the appropriate
option when building in the event they're using a Unix compiler that
doesn't support it by default.

"zdiff3" is identical to ordinary diff3 except that it allows compaction
of common lines on the two sides of history at the beginning or end of
the conflict hunk. For example, the following diff3 conflict:
1
2
3
4
<<<<<<
A
B
C
D
E
||||||
5
6
======
A
X

has common lines 'A', 'C', and 'E' on the two sides. With zdiff3, one
would instead get the following conflict:
1
2
3
4
A
<<<<<<
B
C
D
||||||
5
6
======
X
C
Y
>>>>>>
E
7
8
9
Note that the common lines, 'A', and 'E' were moved outside the
conflict. Unlike with the two-way conflicts from the 'merge'
conflictStyle, the zdiff3 conflict is NOT split into multiple conflict
regions to allow the common 'C' lines to be shown outside a conflict,
because zdiff3 shows the base version too and the base version cannot be
reasonably split.
Note also that the removing of lines common to the two sides might make
the remaining text inside the conflict region match the base text inside
the conflict region (for example, if the diff3 conflict had '5 6 E' on
the right side of the conflict, then the common line 'E' would be moved
outside and both the base and right side's remaining conflict text would
be the lines '5' and '6'). This has the potential to surprise users and
make them think there should not have been a conflict, but there
definitely was a conflict and it should remain.

In the basic `[`/`test` command, the string equality operator is a
single `=`. The `==` operator is only available in `[[`, which is a
bash-ism also supported by zsh.
This mix-up was causing the following completion error in zsh:
> __git_ls_files_helper:7: = not found
(That message refers to the extraneous symbol in `==` ← `=`).
This updates that comparison to use a single `=` inside the
basic `[ … ]` test conditional.
Although this fix is inconsistent with the other comparisons in this
file, which use `[[ … == … ]]`, and the two expressions are functionally
identical in this context, that approach was rejected due to a
preference for `[`.

Remove the sane_grep() shell function in git-sh-setup. The two reasons
for why it existed don't apply anymore:
1. It was added due to GNU grep supporting GREP_OPTIONS. See
e1622bfcba (Protect scripted Porcelains from GREP_OPTIONS insanity,
2009-11-23).
Newer versions of GNU grep ignore that, but even on older versions
its existence won't matter, none of these sane_grep() uses care
about grep's output, they're merely using it to check if a string
exists in a file or stream. We also don't care about the "LC_ALL=C"
that "sane_grep" was using, these greps for fixed or ASCII strings
will behave the same under any locale.
2. The SANE_TEXT_GREP added in 71b401032b (sane_grep: pass "-a" if
grep accepts it, 2016-03-08) isn't needed either, none of these grep
uses deal with binary data.

consistency. I.e. even if the first member is a pointer let's use "0"

In the last few commits we focused on code in unpack-trees.c that
mistakenly removed untracked files or directories. There may be more of
those, but in this commit we change our focus: callers of toplevel
commands that are expected to remove untracked files or directories.
As noted previously, we have toplevel commands that are expected to
delete untracked files such as 'read-tree --reset', 'reset --hard', and
'checkout --force'. However, that does not mean that other highlevel
commands that happen to call these other commands thought about or
conveyed to users the possibility that untracked files could be removed.
Audit the code for such callsites, and add comments near existing
callsites to mention whether these are safe or not.
My auditing is somewhat incomplete, though; it skipped several cases:
* git-rebase--preserve-merges.sh: is in the process of being
deprecated/removed, so I won't leave a note that there are
likely more bugs in that script.
* contrib/git-new-workdir: why is the -f flag being used in a new
empty directory?? It shouldn't hurt, but it seems useless.
* git-p4.py: Don't see why -f is needed for a new dir (maybe it's
not and is just superfluous), but I'm not at all familiar with
the p4 stuff
* git-archimport.perl: Don't care; arch is long since dead
* git-cvs*.perl: Don't care; cvs is long since dead
Also, the reset --hard in builtin/worktree.c looks safe, due to only
running in an empty directory.

Make githooks(5) the source of truth for what hooks git supports, and
punt out early on hooks we don't know about in find_hook(). This
ensures that the documentation and the C code's idea about existing
hooks doesn't diverge.
We still have Perl and Python code running its own hooks, but that'll
be addressed by Emily Shaffer's upcoming "git hook run" command.
This resolves a long-standing TODO item in bugreport.c of there being
no centralized listing of hooks, and fixes a bug with the bugreport
listing only knowing about 1/4 of the p4 hooks. It didn't know about
the recent "reference-transaction" hook either.
We could make the find_hook() function die() or BUG() out if the new
known_hook() returned 0, but let's make it return NULL just as it does
when it can't find a hook of a known type. Making it die() is overly
anal, and unlikely to be what we need in catching stupid typos in the
name of some new hook hardcoded in git.git's sources. By making this
be tolerant of unknown hook names, changes in a later series to make
"git hook run" run arbitrary user-configured hook names will be easier
to implement.
I have not been able to directly test the CMake change being made
here. Since 4c2c38e800 (ci: modification of main.yml to use cmake for
vs-build job, 2020-06-26) some of the Windows CI has a hard dependency
on CMake, this change works there, and is to my eyes an obviously
correct use of a pattern established in previous CMake changes,
namely:
- 061c2240b1 (Introduce CMake support for configuring Git,
2020-06-12)
- 709df95b78 (help: move list_config_help to builtin/help,
2020-04-16)
- 976aaedca0 (msvc: add a Makefile target to pre-generate the Visual
Studio solution, 2019-07-29)
The LC_ALL=C is needed because at least in my locale the dash ("-") is
ignored for the purposes of sorting, which results in a different
order. I'm not aware of anything in git that has a hard dependency on
the order, but e.g. the bugreport output would end up using whatever
locale was in effect when git was compiled.

The "help" builtin has been able to emit configuration variables since
e17ca92637 (completion: drop the hard coded list of config vars,
2018-05-26), but it hasn't produced exactly the format the completion
script wanted. Let's do that.
We got partway there in 2675ea1cc0 (completion: use 'sort -u' to
deduplicate config variable names, 2019-08-13) and
d9438873c4 (completion: deduplicate configuration sections,
2019-08-13), but after both we still needed some sorting,
de-duplicating and awk post-processing of the list.
We can instead simply do the relevant parsing ourselves (we were doing
most of it already), and call string_list_remove_duplicates() after
already sorting the list, so the caller doesn't need to invoke "sort
-u". The "--config-for-completion" output is the same as before after
being passed through "sort -u".
Then add a new "--config-sections-for-completion" option. Under that
output we'll emit config sections like "alias" (instead of "alias." in
the --config-for-completion output).
We need to be careful to leave the "--config-for-completion" option
compatible with users git, but are still running a shell with an older
git-completion.bash. If we e.g. changed the option name they'd see
messages about git-completion.bash being unable to find the
"--config-for-completion" option.
Such backwards compatibility isn't something we should bend over
backwards for, it's only helping users who:
* Upgrade git
* Are in an old shell
* The git-completion.bash in that shell hasn't cached the old
"--config-for-completion" output already.
But since it's easy in this case to retain compatibility, let's do it,
the older versions of git-completion.bash won't care that the input
they get doesn't change after a "sort -u".
While we're at it let's make "--config-for-completion" die if there's
anything left over in "argc", and do the same in the new
"--config-sections-for-completion" option.

Currently, when Git for Windows is built with CMake, the system Git config is

expects it to be in `<runtime-prefix>/mingw64/etc/gitconfig`, the latter in
`<runtime-prefix>/etc/gitconfig`.
Because of this, things like `git clone` do not work correctly (because cURL is
no longer able to find its certificate bundle that it needs to validate HTTPS
certificates). See the full bug report and discussion here:

In 22d5507493 (subtree: don't fuss with PATH, 2021-04-27), `git
subtree` was broken thoroughly on Windows.
The reason is that it assumes Unix semantics, where `PATH` is
colon-separated, and it assumes that `$GIT_EXEC_PATH:` is a verbatim
prefix of `$PATH`. Neither are true, the latter in particular because
`GIT_EXEC_PATH` is a Windows-style path, while `PATH` is a Unix-style
path list.
Let's make extra certain that `$GIT_EXEC_PATH` and the first component
of `$PATH` refer to different entities before erroring out.
We do that by using the `test <path1> -ef <path2>` command that verifies
that the inode of `<path1>` and of `<path2>` is the same.
Sadly, this construct is non-portable, according to
https://pubs.opengroup.org/onlinepubs/009695399/utilities/test.html.
However, it does not matter in practice because we still first look
whether `$GIT_EXEC_PREFIX` is string-identical to the first component of
`$PATH`. This will give us the expected result everywhere but in Git for
Windows, and Git for Windows' own Bash _does_ handle the `-ef` operator.
Just in case that we _do_ need to show the error message _and_ are
running in a shell that lacks support for `-ef`, we simply suppress the
error output for that part.
This fixes https://github.com/git-for-windows/git/issues/3260

Some users have expressed interest in a more "batteries included" way of
building via CMake[1], and a big part of that is providing easier access
to tooling external tools.
A straightforward way to accomplish this is to make it as simple as
possible is to enable the generation of the compile_commands.json file,
which is supported by many tools such as: clang-tidy, clang-format,
sourcetrail, etc.
This does come with a small run-time overhead during the configuration
step (~6 seconds on my machine):
Time to configure with CMAKE_EXPORT_COMPILE_COMMANDS=TRUE
real 1m9.840s
user 0m0.031s
sys 0m0.031s
Time to configure with CMAKE_EXPORT_COMPILE_COMMANDS=FALSE
real 1m3.195s
user 0m0.015s
sys 0m0.015s
This seems like a small enough price to pay to make the project more
accessible to newer users. Additionally there are other large projects
like llvm [2] which has had this enabled by default for >6 years at the
time of this writing, and no real negative consequences that I can find
with my search-skills.
NOTE: That the compile_commands.json is currently produced only when
using the Ninja and Makefile generators. See The CMake documentation[3]
for more info.

When building on windows users have the option to use vcpkg to provide
the dependencies needed to compile. Previously, this was used only when
using the Visual Studio generator which was not ideal because:
- Not all users who want to use vcpkg use the Visual Studio
generators.
- Some versions of Visual Studio 2019 moved away from using the
VS 2019 generator by default, making it impossible for Visual
Studio to configure the project in the likely event that it couldn't
find the dependencies.
- Inexperienced users of CMake are very likely to get tripped up by
the errors caused by a lack of vcpkg, making the above bullet point
both annoying and hard to debug.
As such, let's make using vcpkg the default on windows. Users who want
to avoid using vcpkg can disable it by passing -DNO_VCPKG=TRUE.

Besides being a genuinely useful thing to do, this also just makes sense
and harmonizes which flags may be used when. `git subtree split
--rejoin` amounts to "automatically go ahead and do a `git subtree
merge` after doing the main `git subtree split`", so it's weird and
arbitrary that you can't pass `--squash` to `git subtree split --rejoin`
like you can `git subtree merge`. It's weird that `git subtree split
--rejoin` inherits `git subtree merge`'s `--message` but not `--squash`.
Reconcile the situation by just having `split --rejoin` actually just
call `merge` internally (or call `add` instead, as appropriate), so it
can get access to the full `merge` behavior, including `--squash`.

Just went through the docs looking for anything inaccurate or that can
be improved.
In the '-h' text, in the man page synopsis, and in the man page
description: Normalize the ordering of the list of sub-commands: 'add',
'merge', 'split', 'pull', 'push'. This allows us to kinda separate the
lower-level add/merge/split from the higher-level pull/push.
'-h' text:
- correction: Indicate that split's arg is optional.
- clarity: Emphasize that 'pull' takes the 'add'/'merge' flags.
man page:
- correction: State that all subcommands take options (it seemed to
indicate that only 'split' takes any options other than '-P').
- correction: 'split' only guarantees that the results are identical if
the flags are identical.
- correction: The flag is named '--ignore-joins', not '--ignore-join'.
- completeness: Clarify that 'push' always operates on HEAD, and that
'split' operates on HEAD if no local commit is given.
- clarity: In the description, when listing commands, repeat what their
arguments are. This way the reader doesn't need to flip back and
forth between the command description and the synopsis and the full
description to understand what's being said.
- clarity: In the <variables> used to give command arguments, give
slightly longer, descriptive names. Like <local-commit> instead of
just <commit>.
- clarity: Emphasize that 'pull' takes the 'add'/'merge' flags.
- style: In the synopsis, list options before the subcommand. This
makes things line up and be much more readable when shown
non-monospace (such as in `make html`), and also more closely matches
other man pages (like `git-submodule.txt`).
- style: Use the correct syntax for indicating the options ([<options>]
instead of [OPTIONS]).
- style: In the synopsis, separate 'pull' and 'push' from the other
lower-level commands. I think this helps readability.
- style: Code-quote things in prose that seem like they should be
code-quoted, like '.gitmodules', flags, or full commands.
- style: Minor wording improvements, like more consistent mood (many
of the command descriptions start in the imperative mood and switch
to the indicative mode by the end). That sort of thing.
- style: Capitalize "ID".
- style: Remove the "This option is only valid for XXX command" remarks
from each option, and instead rely on the section headings.

Currently, the $indent variable is just used to track how deeply we're

That is: The indentation-level is hard-coded. It used to be that the

statically, so it made sense to just hard-code it in the

Currently, debug output (triggered by passing '-d') and progress output
stomp on each other. The debug output is just streamed as lines to
stderr, and the progress output is sent to stderr as '%s\r'. When
writing to a file, it is awkward to read and difficult to distinguish
between the debug output and a progress line. When writing to a
terminal the debug lines hide progress lines.
So, when '-d' has been passed, spit out progress as 'progress: %s\n',

The main argument parser goes ahead and tries to parse revs to make

enough special cases for different sub-commands. And it's difficult
having having to think about "is this info coming from an argument, or a
global variable?". So the main argument parser's effort to make things
"simpler" ends up just making it more confusing and complicated.
Begone with the 'revs' global variable; parse 'rev=$(...)' as needed in
individual 'cmd_*' functions.
Begone with the 'default' global variable. Its would-be value is
knowable just from which function we're in.

Scripts needing to fuss with with adding $(git --exec-prefix) PATH
before loading git-sh-setup is a thing of the past. As far as I can
tell, it's been a thing of the past since since Git v1.2.0 (2006-02-12),
or more specifically, since 77cb17e940 (Exec git programs without using
PATH, 2006-01-10). However, it stuck around in contrib scripts and in
third-party scripts for long enough that it wasn't unusual to see.
Originally `git subtree` didn't fuss with PATH, but when people
(including the original subtree author) had problems, because it was a
common thing to see, it seemed that having subtree fuss with PATH was a
reasonable solution.
Here is an abridged history of fussing with PATH in subtree:
2987e6add3 (Add explicit path of git installation by 'git --exec-path', Gianluca Pacchiella, 2009-08-20)
As pointed out by documentation, the correct use of 'git-sh-setup' is
using $(git --exec-path) to avoid problems with not standard
installations.
-. git-sh-setup
+. $(git --exec-path)/git-sh-setup
33aaa697a2 (Improve patch to use git --exec-path: add to PATH instead, Avery Pennarun, 2009-08-26)
If you (like me) are using a modified git straight out of its source
directory (ie. without installing), then --exec-path isn't actually correct.
Add it to the PATH instead, so if it is correct, it'll work, but if it's
not, we fall back to the previous behaviour.
-. $(git --exec-path)/git-sh-setup
+PATH=$(git --exec-path):$PATH
+. git-sh-setup
9c632ea29c ((Hopefully) fix PATH setting for msysgit, Avery Pennarun, 2010-06-24)
Reported by Evan Shaw. The problem is that $(git --exec-path) includes a
'git' binary which is incompatible with the one in /usr/bin; if you run it,
it gives you an error about libiconv2.dll.
+OPATH=$PATH
PATH=$(git --exec-path):$PATH
. git-sh-setup
+PATH=$OPATH # apparently needed for some versions of msysgit
df2302d774 (Another fix for PATH and msysgit, Avery Pennarun, 2010-06-24)
Evan Shaw tells me the previous fix didn't work. Let's use this one
instead, which he says does work.
This fix is kind of wrong because it will run the "correct" git-sh-setup
*after* the one in /usr/bin, if there is one, which could be weird if you
have multiple versions of git installed. But it works on my Linux and his
msysgit, so it's obviously better than what we had before.
-OPATH=$PATH
-PATH=$(git --exec-path):$PATH
+PATH=$PATH:$(git --exec-path)
. git-sh-setup
-PATH=$OPATH # apparently needed for some versions of msysgit
First of all, I disagree with Gianluca's reading of the documentation:
- I haven't gone back to read what the documentation said in 2009, but
in my reading of the 2021 documentation is that it includes "$(git
--exec-path)/" in the synopsis for illustrative purposes, not to say
it's the proper way.
- After being executed by `git`, the git exec path should be the very
first entry in PATH, so it shouldn't matter.
- None of the scripts that are part of git do it that way.
But secondly, the root reason for fussing with PATH seems to be that
Avery didn't know that he needs to set GIT_EXEC_PATH if he's going to
use git from the source directory without installing.
And finally, Evan's issue is clearly just a bug in msysgit. I assume
that msysgit has since fixed the issue, and also msysgit has been
deprecated for 6 years now, so let's drop the workaround for it.
So, remove the line fussing with PATH. However, since subtree *is* in
'contrib/' and it might get installed in funny ways by users
after-the-fact, add a sanity check to the top of the script, checking
that it is installed correctly.

"$*" is for when you want to concatenate the args together,
whitespace-separated; and "$@" is for when you want them to be separate
strings.
There are several places in subtree that erroneously use $@ when
concatenating args together into an error message.
For instance, if the args are argv[1]="dead" and argv[2]="beef", then
the line
die "You must provide exactly one revision. Got: '$@'"
surely intends to call 'die' with the argument
argv[1]="You must provide exactly one revision. Got: 'dead beef'"
however, because the line used $@ instead of $*, it will actually call
'die' with the arguments
argv[1]="You must provide exactly one revision. Got: 'dead"
argv[2]="beef'"
This isn't a big deal, because 'die' concatenates its arguments together
anyway (using "$*"). But that doesn't change the fact that it was a
mistake to use $@ instead of $*, even though in the end $@ still ended
up doing the right thing.

Suport for Git versions older than 1.7.0 (older than February 2010) was
nice to have when git-subtree lived out-of-tree. But now that it lives
in git.git, it's not necessary to keep around. While it's technically
in contrib, with the standard 'git' packages for common systems
(including Arch Linux and macOS) including git-subtree, it seems
vanishingly likely to me that people are separately installing
git-subtree from git.git alongside an older 'git' install (although it
also seems vanishingly likely that people are still using >11 year old
git installs).
Not that there's much reason to remove it either, it's not much code,
and none of my changes depend on a newer git (to my knowledge, anyway;
I'm not actually testing against older git). I just figure it's an easy
piece of fat to trim, in the journey to making the whole thing easier to
hack on.

In this specific case, it's also moving the `set -- -h`, the `git

As far as I can tell, this test isn't actually testing anything, because
someone forgot to tack on `--name-only` to `git log`. This seems to
have been the case since the test was first written, back in fa16ab36ad
("test.sh: make sure no commit changes more than one file at a time.",
2009-04-26), unless `git log` used to do that by default and didn't need
the flag back then?
Convincing myself that it's not actually testing anything was tricky,
the code is a little hard to reason about. It can be made a lot simpler
if instead of trying to parse all of the info from a single `git log`,
we're OK calling `git log` from inside of a loop. And it's my opinion
that tests are not the place for clever optimized code.
So, fix and simplify the test, so that it's actually testing something
and is simpler to reason about.

It's unclear what the purpose of t7900-subtree.sh's
`subtree_test_create_repo` helper function is. It wraps test-lib.sh's,
`test_create_repo` but follows that up by setting log.date=relative. Why
does it set log.date=relative?
My first guess was that at one point the tests required that, but no
longer do, and that the function is now vestigial. I even wrote a patch
to get rid of it and was moments away from `git send-email`ing it.
However, by chance when looking for something else in the history, I
discovered the true reason, from e7aac44ed2 (contrib/subtree: ignore
log.date configuration, 2015-07-21). It's testing that setting
log.date=relative doesn't break `git subtree`, as at one point in the past
that did break `git subtree`.
So, add a comment about this, to avoid future such confusion.

With the introduction of the $__git_cmd_idx variable in e94fb44042
(git-completion.bash: pass $__git_subcommand_idx from __git_main(),
2021-03-24), completion functions were able to know the index at which
the git command is listed, allowing them to skip options that are given
to the underlying git itself, not the corresponding command (e.g.
`-C asdf` in `git -C asdf branch`).
While most of the changes here are self-explanatory, some bear further
explanation.
For the __git_find_on_cmdline() and __git_find_last_on_cmdline() pair of
functions, these functions are only ever called in the context of a git
command completion function. These functions will only care about words
after the command so we can safely ignore the words before this.
For _git_worktree(), this change is technically a no-op (once the
__git_find_last_on_cmdline change is also applied). It was in poor style
to have hard-coded on the index right after `worktree`. In case
`git worktree` were to ever learn to accept options, the current
situation would be inflexible.

Our CMake configuration generates not only build definitions, but also
install definitions: After building Git using `msbuild git.sln`, the
built artifacts can be installed via `msbuild INSTALL.vcxproj`.
To specify _where_ the files should be installed, the
`-DCMAKE_INSTALL_PREFIX=<path>` option can be used when running CMake.
However, this process would really only install the files that were just
built. On Windows, we need more than that: We also need the `.dll` files
of the dependencies (such as libcurl). The `vcpkg` ecosystem, which we
use to obtain those dependencies, can be asked to install said `.dll`
files really easily, so let's do that.
This requires more than just the built `vcpkg` artifacts in the CI build
definition; We now clone the `vcpkg` repository so that the relevant
CMake scripts are available, in particular the ones related to defining
the toolchain.

We are about to add support for installing the `.dll` files of Git's
dependencies (such as libcurl) in the CMake configuration. The `vcpkg`
ecosystem from which we get said dependencies makes that relatively
easy: simply turn on `X_VCPKG_APPLOCAL_DEPS_INSTALL`.
However, current `vcpkg` introduces a limitation if one does that:
While it is totally cool with CMake to specify multiple targets within
one invocation of `install(TARGETS ...) (at least according to
https://cmake.org/cmake/help/latest/command/install.html#command:install),
`vcpkg`'s parser insists on a single target per `install(TARGETS ...)`
invocation.
Well, that's easily accomplished: Let's feed the targets individually to
the `install(TARGETS ...)` function in a `foreach()` look.
This also has the advantage that we do not have to manually cull off the
two entries from the `${PROGRAMS_BUILT}` array before scheduling the
remainder to be installed into `libexec/git-core`. Instead, we iterate
through the array and decide for each entry where it wants to go.

The completion for 'git stash' has not changed in a major way since it
was converted from shell script to builtin. Now that it's a builtin, we
can take advantage of the groundwork laid out by parse-options and use
the generated options.
Rewrite _git_stash() to take use __gitcomp_builtin() to generate
completions for subcommands.
The main `git stash` command does not take any arguments directly. If no
subcommand is given, it automatically defaults to `git stash push`. This
means that we can simplify the logic for when no subcommands have been
given yet. We only have to offer subcommand completions when we're
completing a non-option after "stash".
One area that this patch could improve upon is that the `git stash list`
command accepts log-options. It would be nice if the completion for this
were unified with that of _git_log() and _git_show() which would allow
completions to be provided for options such as `--pretty` but that is
outside the scope of this patch.

Many completion functions perform hardcoded comparisons with $cword.
This fails in the case where the main git command is given arguments
(e.g. `git -C . bundle<TAB>` would fail to complete its subcommands).
Even _git_worktree(), which uses __git_find_on_cmdline(), could still
fail. With something like `git -C add worktree move<TAB>`, the
subcommand would be incorrectly identified as "add" instead of "move".
Assign $__git_subcommand_idx in __git_main(), where the git subcommand
is actually found and the corresponding completion function is called.

Create Unix domain socket based implementation of "simple-ipc".
A set of `ipc_client` routines implement a client library to connect
to an `ipc_server` over a Unix domain socket, send a simple request,
and receive a single response. Clients use blocking IO on the socket.
A set of `ipc_server` routines implement a thread pool to listen for
and concurrently service client connections.
The server creates a new Unix domain socket at a known location. If a
socket already exists with that name, the server tries to determine if
another server is already listening on the socket or if the socket is
dead. If socket is busy, the server exits with an error rather than
stealing the socket. If the socket is dead, the server creates a new
one and starts up.
If while running, the server detects that its socket has been stolen
by another server, it automatically exits.

Create a wrapper class for `unix_stream_listen()` that uses a ".lock"
lockfile to create the unix domain socket in a race-free manner.
Unix domain sockets have a fundamental problem on Unix systems because
they persist in the filesystem until they are deleted. This is
independent of whether a server is actually listening for connections.
Well-behaved servers are expected to delete the socket when they
shutdown. A new server cannot easily tell if a found socket is
attached to an active server or is leftover cruft from a dead server.
The traditional solution used by `unix_stream_listen()` is to force
delete the socket pathname and then create a new socket. This solves
the latter (cruft) problem, but in the case of the former, it orphans
the existing server (by stealing the pathname associated with the
socket it is listening on).
We cannot directly use a .lock lockfile to create the socket because
the socket is created by `bind(2)` rather than the `open(2)` mechanism
used by `tempfile.c`.
As an alternative, we hold a plain lockfile ("<path>.lock") as a
mutual exclusion device. Under the lock, we test if an existing
socket ("<path>") is has an active server. If not, we create a new
socket and begin listening. Then we use "rollback" to delete the
lockfile in all cases.
This wrapper code conceptually exists at a higher-level than the core
unix_stream_connect() and unix_stream_listen() routines that it
consumes. It is isolated in a wrapper class for clarity.

Stash entries can be made with untracked files via
`git stash push --include-untracked`. However, because the untracked
files are stored in the third parent of the stash entry and not the
stash entry itself, running `git stash show` does not include the
untracked files as part of the diff.
With --include-untracked, untracked paths, which are recorded in the
third-parent if it exists, are shown in addition to the paths that have
modifications between the stash base and the working tree in the stash.
It is possible to manually craft a malformed stash entry where duplicate
untracked files in the stash entry will mask tracked files. We detect
and error out in that case via a custom unpack_trees() callback:
stash_worktree_untracked_merge().
Also, teach stash the --only-untracked option which only shows the
untracked files of a stash entry. This is similar to `git show stash^3`
but it is nice to provide a convenient abstraction for it so that users
do not have to think about the underlying implementation.

Long time ago when the _git_complete helper was introduced, _gitk was
replaced with __gitk_main, and a placeholder for backwards compatibility
pointing to __git_wrap_main_gitk was left in place.
When "__git_complete gitk __gitk_main" was called, that created the
__git_wrap__gitk_main helper, which is just basically "__git_func_wrap
__gitk_main" plus `complete` options.
Unfortunately the commit b0a4b2d257 (completion: add support for
backwards compatibility, 2012-05-19) missed a previous instance of a
call to _gitk in _git_gitk
So, basically we had __git_wrap__git_main -> __git_func_wrap __git_main ->
__git_complete_command gitk -> _git_gitk -> _gitk ->
__git_wrap__gitk_main -> __git_func_wrap __gitk_main -> __gitk_main.
There was never any need to call __git_func_wrap twice. Since _git_gitk
is always called inside the wrapper, it can call __gitk_main directly.
And then, in commit 441ecdab37 (completion: bash: remove old compat
wrappers, 2020-10-27) _gitk was removed, which triggers the following
error:
_git_gitk:9: command not found: _gitk

Something changed in `vcpkg` (which we use in our Visual C++ build to
provide the dependencies such as libcurl) and our `vs-build` job started
failing in CI. The reason is that we had a work-around in place to help
CMake find iconv, and this work-around is neither needed nor does it
work anymore.

The command line completion script (in contrib/) learned to expand
commands that are alias of alias.
* fc/bash-completion-alias-of-alias:
completion: bash: improve alias loop detection
completion: bash: check for alias loop
completion: bash: support recursive aliases
It is possible for the name of an alias to end with the name of another
alias, in which case the code will incorrectly detect a loop.
We can fix that by adding an extra space between words.

The variable 'option' is used in __git_ps1_show_upstream()
without being localized.
This clobbers the variable the user may be using for other
purposes, which is bad. Luckily, $option is not used to carry
information around in the script as a global variable. The use
of it in this script has very limited scope (namely, only inside
this function), so just declare that it is "local".

Commit 176f5adfdb wrongly changed the installation path to
'~/.zsh/git-completion.zsh', this ensures the script is not

The whole point of adding the script to the fpath variable is that it's
autoloaded after typing 'git<tab>', which won't happen unless it's named
_git.
I've changed the wording so it's crystal clear the name of the file
*must* be '_git'.

cmake: fall back to using `vcpkg`'s `msgfmt.exe` on Windows
cmake: ensure that the `vcpkg` packages are found on Windows
cmake: do find Git for Windows' shell interpreter
cmake: ignore files generated by CMake as run in Visual Studio

The idea of having CMake support in Git's source tree is to enable
contributors on Windows to start contributing with little effort. To
that end, we just added some sensible defaults that will let users open
the worktree in Visual Studio and start building.
This expects the dependencies (such as zlib) to be available already,
though. If they are not available, we expect the user to run
`compat/vcbuild/vcpkg_install.bat`.
Rather than requiring this step to be manual, detect the situation and
run it as part of the CMake configuration step.
Note that this obviously only applies to the scenario when we want to
compile in Visual Studio (i.e. with MS Visual C), not with GCC.
Therefore, we guard this new code block behind the `MSVC` conditional.
This concludes our journey to make it as effortless as possible to start
developing Git in Visual Studio: all the developer needs to do is to
clone Git's repository, open the worktree via `File>Open>Folder...` and
wait for CMake to finish configuring.
