The contrib/vscode/init.sh script initializes the .vscode directory with
some helpful metadata so VS Code handles Git code better.
One big issue that VS Code has is detecting the tab width based on file
type. ".txt" files were not covered by this script before, so add them
with the appropriate tab widths. This prevents inserting spaces instead
of tabs and keeps the tab width to eight instead of four or two.
While we are here, remove the "editor.wordWrap" settings. The editor's
word wrap is only cosmetic: it does not actually insert newlines when
your typing goes over the column limit. This can make it appear like you
have properly wrapped code, but it is incorrect. Further, existing code
that is over the column limit is wrapped even if your editor window is
wider than the limit. This can make reading such code more difficult.
Without these lines, VS Code renders the lines accurately, without
"ghost" newlines.

Because of the wrapping of the branch name variable $b, the colour codes
in the variable don't get applied, but are instead printed directly in
the output. Move the wrapping of $b to before colour codes are inserted
to correct this. Revert move of branch name colour codes in tests, as
the branch name is now coloured after the wrapping instead of before.

Since 8d4d86b0 (cache: remove null_sha1, 2019-08-18) removed the
is_null_sha1() function, rewrite rules to correct callers of the
function to use is_null_oid() instead has become irrelevant, as any
new callers of the function will get caught by the compiler much
more quickly without spending cycles on Coccinelle.

The short upstream state indicator inherits the colour of the last short
state indicator before it (if there is one), and the sparsity state
indicator inherits this colour as well. This behaviour was introduced by
0ec7c23cdc6 (git-prompt: make upstream state indicator location
consistent, 2022-02-27), while before this change the aforementioned
indicators were white/the default text colour. Some examples to
illustrate this behaviour (assuming all indicators are enabled and
colourization is on):
* If there is something in the stash, both the '$' and the short
upstream state indicator following it will be blue.
* If the local tree has new, untracked files and there is nothing in
the stash, both the '%' and the short upstream state indicator
will be red.
* If all local changes are added to the index and the stash is empty,
both the '+' and the short upstream state indicator following it will
be green.
* If the local tree is clean and there is nothing in the stash, the
short upstream state indicator will be white/${default text colour}.
This appears to be an unintended side-effect of the change, and makes
little sense semantically (e.g. why is it bad to be in sync with
upstream when you have uncommitted local changes?). The cause of the
change in colourization is that previously, the short upstream state
indicator appeared immediately after the rebase/revert/bisect/merge
state indicator (note the position of $p in $gitstring):
local f="$h$w$i$s$u"
local gitstring="$c$b${f:+$z$f}${sparse}$r$p"
Said indicator is prepended with the clear colour code, and the short
upstream state indicator is thus also uncoloured. Now, the short
upstream state indicator follows the sequence of colourized indicators,
without any clearing of colour (again note the position of $p, now in
$f):
local f="$h$w$i$s$u$p"
local gitstring="$c$b${f:+$z$f}${sparse}$r${upstream}"
If the user is in a sparse checkout, the sparsity state indicator
follows a similar pattern to the short upstream state indicator.
However, clearing colour of the colourized indicators changes how the
sparsity state indicator is colourized, as it currently inherits (and
before the change referenced also inherited) the colour of the last
short state indicator before it. Reading the commit message of the
change that introduced the sparsity state indicator, afda36dbf3b
(git-prompt: include sparsity state as well, 2020-06-21), it appears
this colourization also was unintended, so clearing the colour for said
indicator further increases consistency.
Make the colourization of these state indicators consistent by making
all colourized indicators clear their own colour. Make colouring of $c
dependent on it not being empty, as it is no longer being used to colour
the branch name. Move clearing of $b's prefix to before colourization so
it gets cleared properly when colour codes are inserted into it. These
changes make changing the layout of the prompt less prone to unintended
colour changes in the future.
Change coloured Bash prompt tests to reflect the colourization changes:
* Move the colour codes to wrap the expected content of the expanded
$__git_ps1_branch_name in all tests.
* Insert a clear-colour code after the symbol for the first indicator
in "prompt - bash color pc mode - dirty status indicator - dirty
index and worktree", to reflect that all indicators should clear
their own colour.

When operating at the scale that Scalar wants to support, certain data

Over the course of Scalar's development, it became obvious that there is
a need for a command that can gather all kinds of useful information
that can help identify the most typical problems with large
worktrees/repositories.
The `diagnose` command is the culmination of this hard-won knowledge: it
gathers the installed hooks, the config, a couple statistics describing
the data shape, among other pieces of information, and then wraps
everything up in a tidy, neat `.zip` archive.
Note: originally, Scalar was implemented in C# using the .NET API, where
we had the luxury of a comprehensive standard library that includes
basic functionality such as writing a `.zip` file. In the C version, we
lack such a commodity. Rather than introducing a dependency on, say,
libzip, we slightly abuse Git's `archive` machinery: we write out a
`.zip` of the empty try, augmented by a couple files that are added via
the `--add-file*` options. We are careful trying not to modify the
current repository in any way lest the very circumstances that required
`scalar diagnose` to be run are changed by the `diagnose` run itself.

The `scalar` command needs a Scalar enlistment for many subcommands, and
looks in the current directory for such an enlistment (traversing the
parent directories until it finds one).
These is subcommands can also be called with an optional argument
specifying the enlistment. Here, too, we traverse parent directories as
needed, until we find an enlistment.
However, if the specified directory does not even exist, or is not a
directory, we should stop right there, with an error message.

Create another thread to watch over the daemon process and
automatically shut it down if necessary.
This commit creates the basic framework for a "health" thread
to monitor the daemon and/or the file system. Later commits
will add platform-specific code to do the actual work.
The "health" thread is intended to monitor conditions that
would be difficult to track inside the IPC thread pool and/or
the file system listener threads. For example, when there are
file system events outside of the watched worktree root or if
we want to have an idle-timeout auto-shutdown feature.
This commit creates the health thread itself, defines the thread-proc
and sets up the thread's event loop. It integrates this new thread
into the existing IPC and Listener thread models.
This commit defines the API to the platform-specific code where all of
the monitoring will actually happen.
The platform-specific code for MacOS is just stubs. Meaning that the
health thread will immediately exit on MacOS, but that is OK and
expected. Future work can define MacOS-specific monitoring.
The platform-specific code for Windows sets up enough of the
WaitForMultipleObjects() machinery to watch for system and/or custom
events. Currently, the set of wait handles only includes our custom
shutdown event (sent from our other theads). Later commits in this
series will extend the set of wait handles to monitor other
conditions.

Extend generic incompatibility checkout with platform-specific
mechanism. Stub in Win32 version.
In the existing fsmonitor-settings code we have a way to mark
types of repos as incompatible with fsmonitor (whether via the
hook and IPC APIs). For example, we do this for bare repos,
since there are no files to watch.
Extend this exclusion mechanism for platform-specific reasons.

13092a91 (cocci: refactor common patterns to use xstrdup_or_null(),
2016-10-12) introduced a rule to rewrite this conditional call to
xstrdup(E) and an assignment to variable V:
- if (E)
- V = xstrdup(E);
into an unconditional call to xstrdup_or_null(E) and an assignment
to variable V:
+ V = xstrdup_or_null(E);
which is utterly bogus. The original code may already have an
acceptable value in V and the conditional assignment may be to
improve the value already in V with a copy of a better value E when
(and only when) E is not NULL.
The rewritten construct unconditionally discards the existing value
of V and replaces it with a copy of E, even when E is NULL, which
changes the meaning of the program.
By the way, if it were
-if (E && !V)
- V = xstrdup(E);
+V = xstrdup_or_null(E);
it would probably have been correct. But there is no existing code
that would have been improved by such a rule, so let's just remove
the bogus one without replacing with the more specific one.

Remove the 'reset.quiet' config option, remove '--no-quiet' documentation in
'Documentation/git-reset.txt'. In 4c3abd0551 (reset: add new reset.quiet
config setting, 2018-10-23), 'reset.quiet' was introduced as a way to
globally change the default behavior of 'git reset --mixed' to skip index
refresh.
However, now that '--quiet' does not affect index refresh, 'reset.quiet'
would only serve to globally silence logging. This was not the original
intention of the config setting, and there's no precedent for such a setting
in other commands with a '--quiet' option, so it appears to be obsolete.
In addition to the options & its documentation, remove 'reset.quiet' from
the recommended config for 'scalar'.

Use a pipe as a separator before long upstream state indicator. This is
consistent with long state indicators for sparse and in-progress
operations (e.g. merge).
For comparison, `__git_ps1` examples without upstream state indicator:
(main)
(main %)
(main *%)
(main|SPARSE)
(main %|SPARSE)
(main *%|SPARSE)
(main|SPARSE|REBASE 1/2)
(main %|SPARSE|REBASE 1/2)
Note that if there are long state indicators, they appear after short
state indicators if there are any, or after the branch name if there are
no short state indicators. Each long state indicator begins with a pipe
(`|`) as a separator.

Make upstream state indicator location more consistent with similar
state indicators (e.g. sparse). Group the short upstream state indicator
(`=`, `<`, `>`, or `<>`) with other short state indicators immediately
after the branch name. Previously short and long upstream state
indicators appeared after all other state indicators.
Use a separator (`SP` or `GIT_PS1_STATESEPARATOR`) between branch name
and short upstream state indicator. Previously the short upstream state
indicator would sometimes appear directly adjacent to the branch name
instead of being separated.
For comparison, `__git_ps1` examples without upstream state indicator:
(main)
(main %)
(main *%)
(main|SPARSE)
(main %|SPARSE)
(main *%|SPARSE)
(main|SPARSE|REBASE 1/2)
(main %|SPARSE|REBASE 1/2)
Note that if there are short state indicators, they appear together
after the branch name and separated from it by `SP` or
`GIT_PS1_STATESEPARATOR`.
Before/after examples with short upstream state indicator:
| Before | After |
| ---------------- | ---------------- |
| (main=) | (main =) |
| (main|SPARSE=) | (main =|SPARSE) |
| (main %|SPARSE=) | (main %=|SPARSE) |

If no --args are present after 'git restore', it assumes that you
want to tab-complete one of the files with unstaged uncommitted

If a file has been staged, we don't want to list it, as restoring those

This commit introduces the `core.fsyncMethod` configuration
knob, which can currently be set to `fsync` or `writeout-only`.
The new writeout-only mode attempts to tell the operating system to
flush its in-memory page cache to the storage hardware without issuing a
CACHE_FLUSH command to the storage controller.
Writeout-only fsync is significantly faster than a vanilla fsync on
common hardware, since data is written to a disk-side cache rather than
all the way to a durable medium. Later changes in this patch series will
take advantage of this primitive to implement batching of hardware
flushes.
When git_fsync is called with FSYNC_WRITEOUT_ONLY, it may fail and the
caller is expected to do an ordinary fsync as needed.
On Apple platforms, the fsync system call does not issue a CACHE_FLUSH
directive to the storage controller. This change updates fsync to do
fcntl(F_FULLFSYNC) to make fsync actually durable. We maintain parity
with existing behavior on Apple platforms by setting the default value
of the new core.fsyncMethod option.

The $(QUIET) variables we define are largely duplicated between our

Since we're not using the environment to pass these around we don't
need to export the "QUIET_GEN" and "QUIET_BUILT_IN" variables
anymore. The "QUIET_GEN" variable is used in "git-gui/Makefile" and
"gitweb/Makefile", but they've got their own definition for those. The
"QUIET_BUILT_IN" variable is only used in the top-level "Makefile". We
still need to export the "V" variable.

We have various behavior that's shared across our Makefiles, or that
really should be (e.g. via defined templates). Let's create a
top-level "shared.mak" to house those sorts of things, and start by
adding the ".DELETE_ON_ERROR" flag to it.
See my own 7b76d6bf221 (Makefile: add and use the ".DELETE_ON_ERROR"
flag, 2021-06-29) and db10fc6c09f (doc: simplify Makefile using
.DELETE_ON_ERROR, 2021-05-21) for the addition and use of the
".DELETE_ON_ERROR" flag.
I.e. this changes the behavior of existing rules in the altered
Makefiles (except "Makefile" & "Documentation/Makefile"). I'm
confident that this is safe having read the relevant rules in those
Makfiles, and as the GNU make manual notes that it isn't the default
behavior is out of an abundance of backwards compatibility
caution. From edition 0.75 of its manual, covering GNU make 4.3:
[Enabling '.DELETE_ON_ERROR' is] almost always what you want
'make' to do, but it is not historical practice; so for
compatibility, you must explicitly request it.
This doesn't introduce a bug by e.g. having this
".DELETE_ON_ERROR" flag only apply to this new shared.mak, Makefiles
have no such scoping semantics.
It does increase the danger that any Makefile without an explicit "The
default target of this Makefile is..." snippet to define the default
target as "all" could have its default rule changed if our new
shared.mak ever defines a "real" rule. In subsequent commits we'll be
careful not to do that, and such breakage would be obvious e.g. in the
case of "make -C t".
We might want to make that less fragile still (e.g. by using
".DEFAULT_GOAL" as noted in the preceding commit), but for now let's
simply include "shared.mak" without adding that boilerplate to all the
Makefiles that don't have it already. Most of those are already
exposed to that potential caveat e.g. due to including "config.mak*".

The script uses "git show -s" to display the title of the merge
commit being studied, without explicitly disabling the pager, which
is not a safe thing to do in a script.
For example, when the pager is set to "less" with "-SF" options (-S
tells the pager not to fold lines but allow horizontal scrolling to
show the overly long lines, -F tells the pager not to wait if the
output in its entirety is shown on a single page), and the title of
the merge commit is longer than the width of the terminal, the pager
will wait until the end-user tells it to quit after showing the
single line.
Explicitly disable the pager with this "git show" invocation to fix
this.
The command uses the "--pretty=format:..." format, which adds LF in
between each pair of commits it outputs, which means that the label
for the merge being learned from will be followed by the next
message on the same line. "--pretty=tformat:..." is what we should
instead, which adds LF after each commit, or a more modern way to
spell it, i.e. "--format=...". This existing breakage becomes
easier to see, now we no longer use the pager.

Update the __gitcomp_directories method to de-quote and handle unusual

to re-use the logic in __git_index_files, this method removed
subdirectories (e.g. folder1/0/ became folder1/), so instead new custom
logic was placed directly in the __gitcomp_directories method.
Note there are two tests for this new functionality - one for spaces and
accents and one for backslashes and tabs. The backslashes and tabs test
uses FUNNYNAMES to avoid running on Windows. This is because:
1. Backslashes are explicitly not allowed in Windows file paths.
2. Although tabs appear to be allowed when creating a file in a Windows
bash shell, they actually are not renderable (and appear as empty boxes
in the shell).

Correct multiple issues with tab completion of the git sparse-checkout
command. These issues were:
1. git sparse-checkout <TAB> previously resulted in an incomplete list of
subcommands (it was missing reapply and add).
2. Subcommand options were not tab-completable.
3. git sparse-checkout set <TAB> and git sparse-checkout add <TAB> showed
both file names and directory names. While this may be a less surprising
behavior for non-cone mode, cone mode sparse checkouts should complete
only directory names.
Note that while the new strategy of just using git ls-tree to complete on
directory names is simple and a step in the right direction, it does have
some caveats. These are:
1. Likelihood of poor performance in large monorepos (as a result of
recursively completing directory names).
2. Inability to handle paths containing unusual characters.
These caveats will be fixed by subsequent commits in this series.

The `git` executable has these two very useful options:
-C <directory>:
switch to the specified directory before performing any actions
-c <key>=<value>:
temporarily configure this setting for the duration of the
specified scalar subcommand
With this commit, we teach the `scalar` executable the same trick.
Note: It might look like a good idea to try to reuse the
`handle_options()` function in `git.c` instead of replicating only the
`-c`/`-C` part. However, that function is not only not in `libgit.a`, it
is also intricately entangled with the rest of the code in `git.c` that
is necessary e.g. to handle `--paginate`. Besides, no other option
handled by that `handle_options()` function is relevant to Scalar,
therefore the cost of refactoring vastly would outweigh the benefit.

There are many situations in which having access to a cryptographically
secure pseudorandom number generator (CSPRNG) is helpful. In the
future, we'll encounter one of these when dealing with temporary files.
To make this possible, let's add a function which reads from a system
CSPRNG and returns some bytes.
We know that all systems will have such an interface. A CSPRNG is
required for a secure TLS or SSH implementation and a Git implementation
which provided neither would be of little practical use. In addition,
POSIX is set to standardize getentropy(2) in the next version, so in the
(potentially distant) future we can rely on that.
For systems which lack one of the other interfaces, we provide the
ability to use OpenSSL's CSPRNG. OpenSSL is highly portable and
functions on practically every known OS, and we know it will have access
to some source of cryptographically secure randomness. We also provide
support for the arc4random in libbsd for folks who would prefer to use
that.
Because this is a security sensitive interface, we take some
precautions. We either succeed by filling the buffer completely as we
requested, or we fail. We don't return partial data because the caller
will almost never find that to be a useful behavior.
Specify a makefile knob which users can use to specify one or more
suitable CSPRNGs, and turn the multiple string options into a set of
defines, since we cannot match on strings in the preprocessor. We allow
multiple options to make the job of handling this in autoconf easier.
The order of options is important here. On systems with arc4random,
which is most of the BSDs, we use that, since, except on MirBSD and
macOS, it uses ChaCha20, which is extremely fast, and sits entirely in
userspace, avoiding a system call. We then prefer getrandom over
getentropy, because the former has been available longer on Linux, and
then OpenSSL. Finally, if none of those are available, we use
/dev/urandom, because most Unix-like operating systems provide that API.
We prefer options that don't involve device files when possible because
those work in some restricted environments where device files may not be
available.
Set the configuration variables appropriately for Linux and the BSDs,
including macOS, as well as Windows and NonStop. We specifically only
consider versions which receive publicly available security support
here. For the same reason, we don't specify getrandom(2) on Linux,
because CentOS 7 doesn't support it in glibc (although its kernel does)
and we don't want to resort to making syscalls.
Finally, add a test helper to allow this to be tested by hand and in
tests. We don't add any tests, since invoking the CSPRNG is not likely
to produce interesting, reproducible results.

315a84f9aa0 (subtree: use commits before rejoins for splits, 2018-09-28)
changed the signature of check_parents from 'check_parents [REV...]'
to 'check_parents PARENTS_EXPR INDENT'. In other words the variable list
of parent revisions became a list embedded in a string. However it
neglected to unpack the list again before sending it to cache_miss,
leading to incorrect calls whenever more than one parent was present.
This is the case whenever a merge commit is processed, with the end
result being a loss of performance from unecessary rechecks.
The indent parameter was subsequently removed in e9525a8a029 (subtree:
have $indent actually affect indentation, 2021-04-27), but the argument
handling bug remained.
For consistency, take multiple arguments in check_parents,
and pass all of them to cache_miss separately.

Failures within `for` and `while` loops can go unnoticed if not detected
and signaled manually since the loop itself does not abort when a
contained command fails, nor will a failure necessarily be detected when
the loop finishes since the loop returns the exit code of the last
command it ran on the final iteration, which may not be the command
which failed. Therefore, detect and signal failures manually within

because it was versioned independently of Git.
Since Scalar is now tightly coupled with Git, it does not make sense for
them to show different versions. Therefore, it shows the same output as

`scalar version` prints to `stderr`, though (`git version` prints to

This implements Scalar's opinionated `clone` command: it tries to use a
partial clone and sets up a sparse checkout by default. In contrast to
`git clone`, `scalar clone` sets up the worktree in the `src/`
subdirectory, to encourage a separation between the source files and the
build output (which helps Git tremendously because it avoids untracked
files that have to be specifically ignored when refreshing the index).
Also, it registers the repository for regular, scheduled maintenance,
and configures a flurry of configuration settings based on the
experience and experiments of the Microsoft Windows and the Microsoft
Office development teams.
Note: since the `scalar clone` command is by far the most commonly
called `scalar` subcommand, we document it at the top of the manual
page.

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
C
Y
E
>>>>>>
7
8
9
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.

Fix long-standing shell syntax error in the completion script.
* re/completion-fix-test-equality:
completion: fix incorrect bash/zsh string equality check
|
|
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
e1622bfcbad (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 71b401032b9 (sane_grep: pass "-a" if
grep accepts it, 2016-03-08) isn't needed either, none of these grep
uses deal with binary data.

In C it isn't required to specify that all members of a struct are
zero'd out to 0, NULL or '\0', just providing a "{ 0 }" will
accomplish that.
Let's also change code that provided N zero'd fields to just
provide one, and change e.g. "{ NULL }" to "{ 0 }" for
consistency. I.e. even if the first member is a pointer let's use "0"
instead of "NULL". The point of using "0" consistently is to pick one,

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
e17ca926371 (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 2675ea1cc0f (completion: use 'sort -u' to
deduplicate config variable names, 2019-08-13) and
d9438873c4d (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.

To help users transition who still did not receive the memo about the
deprecation, we offer a helpful error message instead of throwing our
hands in the air and saying that we don't know that option, never heard
of it.

__gitcomp automatically adds a suffix, but __gitcomp_nl and others
don't, we need to specify a space by default.
Can be tested with:
git config branch.autoSetupMe<tab>
This fix only works for versions of bash greater than 4.0, before that
"local sfx" creates an empty string, therefore the unset expansion
doesn't work. The same happens in zsh.
Therefore we don't add the test for that for now.
The correct fix for all shells requires semantic changes in __gitcomp,
but that can be done later.

Currently, when Git for Windows is built with CMake, the system Git config is
expected in a different location than when building via `make`: the former
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:
https://github.com/git-for-windows/git/issues/3071#issuecomment-789261386.

In 22d550749361 (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.

[PATCH]: contrib/completion/git-completion.bash, there is a construct
where comment lines are placed between the command that is on

Unfortunately, this script is also used by Zsh completion, but
Zsh mishandles this construct when "interactive_comments" option is not
set (by default it is off on macOS), resulting in a breakage:
$ git worktree remove [TAB]
$ git worktree remove __git_complete_worktree_paths:7: command not found: #
Move the comment, even though it explains what happens on the
downstream of the pipe and logically belongs where it is right

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.
- style: Since that line is getting edited anyway, switch "behaviour" to
American "behavior".
- style: Trim trailing whitespace.

Currently, the $indent variable is just used to track how deeply we're
nested, and the debug log is indented by things like
debug " foo"
That is: The indentation-level is hard-coded. It used to be that the
code couldn't recurse, so the indentation level could be known
statically, so it made sense to just hard-code it in the
output. However, since 315a84f9aa ("subtree: use commits before rejoins

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',
instead of as '%s\r', so that it can be detected, and so that the debug
lines don't overwrite the progress when written to a terminal.

For each function in subtree, add a usage comment saying what the
arguments are, and add an `assert` checking the number of arguments.
In figuring out each thing's arguments in order to write those comments
and assertions, it turns out that find_existing_splits is written as if
it takes multiple 'revs', but it is in fact only ever passed a single
'rev':
unrevs="$(find_existing_splits "$dir" "$rev")" || exit $?

The main argument parser goes ahead and tries to parse revs to make
things simpler for the sub-command implementations. But, it includes
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.
Begone with the 'ensure_single_rev' function. Its functionality can be
achieved by passing '--verify' to 'git rev-parse'.

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.

Ensure that every $(subshell) that calls a function (as opposed to an
external executable) is followed by `|| exit $?`. Similarly, ensure that
every `cmd | while read; do ... done` loop is followed by `|| exit $?`.
Both of those constructs mean that it can miss `die` calls, and keep
running when it shouldn't.

Shove all of the loose code inside of a main() function.
This comes down to personal preference more than anything else. A
preference that I've developed over years of maintaining large Bash
scripts, but still a mere personal preference.
In this specific case, it's also moving the `set -- -h`, the `git
rev-parse --parseopt`, and the `. git-sh-setup` to be closer to all
the rest of the argument parsing, which is a readability win on its
own, IMO.

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.
And while at it, go ahead and (1) touch up the function to avoid a
pointless subshell and (2) update the one test that didn't use it.

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.

In e94fb44042 (git-completion.bash: pass $__git_subcommand_idx from
__git_main(), 2021-03-24), the $__git_subcommand_idx variable was
introduced. Naming it after the index of the subcommand is needlessly
confusing as, when this variable is used, it is in the completion
functions for commands (e.g. _git_remote()) where for `git remote add`,
the `remote` is referred to as the command and `add` is referred to as
the subcommand.
Rename this variable so that it's obvious it's about git commands. While
we're at it, shorten up its name so that it's still readable without
being a handful to type.

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.
