[PATCH]: contrib/completion/git-completion.bash, there is a construct
where comment lines are placed between the command that is on
the upstream of a pipe and the command that is on the downstream
of a pipe in __git_complete_worktree_paths function.
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
now, before the entire pipeline, to work around this problem.

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.

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

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.
Use this variable to replace hardcoded comparisons with $cword.

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
