93ab00bd85 contrib/completion: complete options that take refs for format-patch
The completion for format-patch currently suggests --base=, --interdiff=
and --range-diff= as options. However, with these `=` forms of the
options, there is no space and we'd enter the `--*` case which means we
don't call the __git_complete_revlist() at the end.

Teach _git_format_patch() to complete refs in the case of --base=,
--interdiff= and --range-diff=.

308d7a7dc9 contrib/completion: extract common diff/difftool options
difftool parses its own options and then passes the remaining options
onto diff. As a result, they share common command-line options. Instead
of duplicating the list, use a shared $__git_diff_difftool_options list.

The completion for diff is missing --relative and the completion for
difftool is missing --no-index. Add both of these to the common list.

fc47391e24 drop vcs-svn experiment
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.

b5dd96b70a make credential helpers builtins
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).

7f475e2780 cmake: support for building git on windows with msvc and clang.
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
set CC=Clang
cmake `relative-path-to-srcdir` -G Ninja
		-DCMAKE_BUILD_TYPE=[Debug or Release]

c4b2f41b5f cmake: support for testing git with ctest
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.

afda36dbf3 git-prompt: include sparsity state as well
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.

We remove members `graph_pos` and `generation` from the struct commit.
The default assignments in init_commit_node() are no longer valid,

061c2240b1 Introduce CMake support for configuring Git
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.

91439928ec completion: improve handling of --orphan option of switch/checkout
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.

Update the previously added test cases as they are now passing.

acb658fe7d completion: improve handling of -c/-C and -b/-B in switch/checkout
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.

00e7bd2b00 completion: improve handling of --track in switch/checkout
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.

68d97c7fdd completion: improve completion for git switch with no options
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.

4e79adf4e5 completion: improve handling of DWIM mode for switch/checkout
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.

688077910b completion: perform DWIM logic directly in __git_complete_refs
__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.

58a2ca37a1 completion: extract function __git_dwim_remote_heads
__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.

0408c6b412 completion: replace overloaded track term for __git_complete_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.

This harms any subcommand that can take the "-p" option---even when the

c0af173a13 completion: fix 'git add' on paths under an untracked directory
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.

c839fcff65 import-tars: ignore the global PAX header
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.

These options are available since git v2.15, but somehow
eluded from the completion script.

Note that while --color-moved-ws= accepts comma-separated
list of values, there is no (easy?) way to make it work

aa416b22ea am: support --show-current-patch=diff to retrieve .git/rebase-apply/patch
When "git am --show-current-patch" was added in commit 984913a210 ("am:
add --show-current-patch", 2018-02-12), "git am" started recommending it
as a replacement for .git/rebase-merge/patch.  Unfortunately the suggestion
is somewhat misguided; for example, the output of "git am --show-current-patch"
cannot be passed to "git apply" if it is encoded as quoted-printable
or base64.  Add a new mode to "git am --show-current-patch" in order to
straighten the suggestion.

f3b4822899 am: support --show-current-patch=raw as a synonym for--show-current-patch
When "git am --show-current-patch" was added in commit 984913a210 ("am:
add --show-current-patch", 2018-02-12), "git am" started recommending it
as a replacement for .git/rebase-merge/patch.  Unfortunately the suggestion
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".

6d04ce75c4 git-prompt: change the prompt for interactive-based rebases
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".

Complete paths after 'git worktree add <TAB>' and refs after 'git
worktree add -b <TAB>' and 'git worktree add some/dir <TAB>'.

Uncharacteristically for a Git command, 'git worktree add' takes a
mandatory path parameter before a commit-ish as its optional last
parameter.  In addition, it has both standalone --options and options
with a mandatory unstuck parameter ('-b <new-branch>').  Consequently,
trying to complete refs for that last optional commit-ish parameter
resulted in a more convoluted than usual completion function, but
hopefully all the included comments will make it not too hard to
digest.

3027e4f9a8 completion: list existing working trees for 'git worktree' subcommands
Complete the paths of existing working trees for 'git worktree's
'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.

Combine these into a single case arm to avoid repetition.

Note that after this change we won't complete 'git worktree remove's

The __git_find_on_cmdline() helper function started its life as
__git_find_subcommand() [1], but it served a more general purpose than

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.

While at it, add a short comment describing the function's purpose.

1f0fc1db85 pretty: implement 'reference' format
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.

b19f3fe9dd hex: drop sha1_to_hex()
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",

instead of `--onto `.

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.

Teach _git_rebase() to complete refs in the `--onto=` case so that we

fe0ed5d5e9 contrib/buildsystems: fix Visual Studio Debug configuration
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
   the first occurrence. However, some projects have it listed twice.
   Previously this bug was hidden, because Debug path was never taken.
   I decided that avoiding double -lz in makefile is fragile and I'd
   better replace all occurrences instead.
3) In Debug, 'libcurl-d.lib' should be used instead of 'libcurl.lib'.
   Previously this bug was hidden, because Debug path was never taken.

aeeb978ba6 completion: teach archive to use __gitcomp_builtin
Currently, _git_archive() uses a hardcoded list of options for its
completion. However, we can use __gitcomp_builtin() to get a dynamically
generated list of completions instead.

Teach _git_archive() to use __gitcomp_builtin() so that newly
implemented options in archive will be automatically completed without
any mucking around in git-completion.bash. While we're at it, teach it
to complete the missing `--worktree-attributes` option as well.

Unfortunately, since some args are passed through from cmd_archive() to
write_archive() (which calls parse_archive_args()), there's no way that a
`--git-completion-helper` arg can end up reaching parse_archive_args()
since the first call to parse_options() will end up calling exit(0). As
a result, we have to carry the options supported by write_archive() in
the hardcoded string.

9df53c5de6 Recommend git-filter-repo instead of git-filter-branch
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.

414d924beb rebase: teach rebase --keep-base
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.

5af9d5f6c8 completion: complete config variables and values for 'git clone --config='
Completing configuration sections and variable names for the stuck
argument of 'git clone --config=<TAB>' requires a bit of extra care
compared to doing the same for the unstuck argument of 'git clone

Add an option to the __git_complete_config_variable_name_and_value()

functions to specify the current section/variable name to be
completed, so they can be used even when completing the stuck argument
of '--config='.

__git_complete_config_variable_value() already has such an option, and

e1e00089da completion: complete configuration sections and variable names for 'git -c'
'git config' expects a configuration variable's name and value in

them in a single option joined by a '=' character, i.e.
'section.name=value', so we should append a '=' character to each

typing the value right away.

Add an option to the __git_complete_config_variable_name() function to
allow callers to specify an alternate suffix to add, and use it to

d9ee1e0617 completion: simplify inner 'case' pattern in __gitcomp()
The second '*' in the '--*=*' pattern of the inner 'case' statement of
the __gitcomp() helper function never matches anything, so let's use
'--*=' 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
completed separately.

d9438873c4 completion: deduplicate configuration sections
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.

840d7e5b3c completion: complete more values of more 'color.*' configuration variables
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

b18ae14a8f vcxproj: also link-or-copy builtins
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.

976aaedca0 msvc: add a Makefile target to pre-generate the Visual Studio solution
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.

384a61bc6a contrib/buildsystems: add a backend for modern Visual Studio versions
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.

03aa7118c3 contrib/buildsystems: redirect errors of the dry run into a log file
Rather than swallowing the errors, it is better to have them in a file.

To make it obvious what this is about, use the file name
'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
GITGUI_VERSION if they were generated by the make file. They are omitted
if the release is tagged and indentically defined in their respective
GIT_VERSION_GEN file DEF_VER variables.

177fbab747 coccinelle: use COPY_ARRAY for copying arrays
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.

69702523af completion: do not cache if --git-completion-helper fails
"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
  good.

e693237e2b list-objects-filter: disable 'sparse:path' filters
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.

301b8c7f40 commit.c: add repo_get_commit_tree()
Remove the implicit dependency on the_repository in this function.
It will be used in sha1-name.c functions when they are updated to take
any 'struct repository'. get_commit_tree() remains as a compat wrapper,
to be slowly replaced later.

Any access to "maybe_tree" field directly will result in _broken_ code
after running through commit.cocci because we can't know what is the
right repository to use.

the_repository would be correct most of the time. But we're relying less
and less on the_repository and that assumption may no longer be
true. The transformation now is more of a poor man replacement for a C++
compiler catching access to private fields.

a133c40b23 commit.cocci: refactor code, avoid double rewrite
"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.

28c23cd4c3 strbuf.cocci: suggest strbuf_addbuf() to add one strbuf to an other
The best way to add one strbuf to an other is via:

  strbuf_addbuf(&sb, &sb2);

This is a bit more idiomatic and efficient than:

  strbuf_addstr(&sb, sb2.buf);

because the size of the second strbuf is known and thus it can spare a
strlen() call, and much more so than:

  strbuf_addf(&sb, "%s", sb2.buf);

because it can spare the whole vsnprintf() formatting magic.

Add new semantic patches to 'contrib/coccinelle/strbuf.cocci' to catch
these undesired patterns and to suggest strbuf_addbuf() instead.

Luckily, our codebase is already clean from any such undesired
patterns (but one of the in-flight topics just tried to sneak in such
a strbuf_addf() call).

974e4a85e3 cache: make oidcpy always copy GIT_MAX_RAWSZ bytes
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.

6d54f528c7 completion: treat results of git ls-tree as file paths
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/'.

7a478b36aa zsh: complete unquoted paths with spaces correctly
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.

13374987dd completion: use __gitcomp_builtin for format-patch
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.

c6f050a434 mingw: load system libraries the recommended way
When we access IPv6-related functions, we load the corresponding system
library using the `LoadLibrary()` function, which is not the recommended
way to load system libraries.

In practice, it does not make a difference: the `ws2_32.dll` library
containing the IPv6 functions is already loaded into memory, so
LoadLibrary() simply reuses the already-loaded library.

Still, recommended way is recommended way, so let's use that instead.

While at it, also adjust the code in contrib/ that loads system libraries.

05b4ed61f4 cocci: simplify "if (++u > 1)" to "if (u++)"
It is more common to use post-increment than pre-increment when the
side effect is the primary thing we want in our code and in C in
general (unlike C++).

Initializing a variable to 0, incrementing it every time we do
something, and checking if we have already done that thing to guard
the code to do that thing, is easier to understand when written

	if (u++)
		; /* we've done that! */
	else
		do_it(); /* just once. */

but if you try to use pre-increment, you end up with a less natural
looking

	if (++u > 1)

6afedba8c9 object_id.cocci: match only expressions of type 'struct object_id'
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'.

19ad68d95d subtree: performance improvement for finding unexpected parent commits
After testing a previous patch at larger scale, a performance issue was
detected when using git show to locate parent revisions, with a single
run of the git show command taking 2 seconds or longer in a complex repo.
When the command is required tens or hundreds of times in a run of the

with git rev-parse resulted in significantly increased performance, with
the command in question returning instantly.

783faedd65 contrib: add coverage-diff script
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.

68f8ff8151 subtree: improve decision on merges kept in split
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.

315a84f9aa subtree: use commits before rejoins for splits
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.

dd21d43b58 subtree: make --ignore-joins pay attention to adds
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.

9001dc2a74 convert "oidcmp() != 0" to "!oideq()"
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.

e3ff0683e2 convert "hashcmp() == 0" to hasheq()
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)".

4a7e27e957 convert "oidcmp() == 0" to oideq()
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).

4d168e742a coccinelle: use <...> for function exclusion
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).

6a8ad880f0 subtree test: simplify preparation of expected results
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:

12861e200a vscode: let cSpell work on commit messages, too
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.

2a2cdd069a vscode: add a dictionary for cSpell
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.

0f47f78e02 vscode: only overwrite C/C++ settings
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.

54c06c6013 contrib: add a script to initialize VS Code configuration
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

top level folder of Git's source code in VS Code.

627be1538d git-credential-netrc: remove use of "autodie"
The "autodie" module was added in Perl 5.10.1, but our INSTALL
document says "version 5.8 or later is needed".

As discussed in <87efhfvxzu.fsf@evledraar.gmail.com> this script is in
contrib/, so we might not want to apply that policy, however in this
case "autodie" was recently added as a "gratuitous safeguard" in
786ef50a23 ("git-credential-netrc: accept gpg option",
2018-05-12) (see
<CAHqJXRE8OKSKcck1APHAHccLZhox+tZi8nNu2RA74RErX8s3Pg@mail.gmail.com>).

Looking at it more carefully the addition of "autodie" inadvertently
introduced a logic error, since having it is equivalent to this patch:

    @@ -245,10 +244,10 @@ sub load_netrc {
     	if ($gpgmode) {
     		my @cmd = ($options{'gpg'}, qw(--decrypt), $file);
     		log_verbose("Using GPG to open $file: [@cmd]");
    -		open $io, "-|", @cmd;
    +		open $io, "-|", @cmd or die "@cmd: $!";
     	} else {
     		log_verbose("Opening $file...");
    -		open $io, '<', $file;
    +		open $io, '<', $file or die "$file: $!$!;
     	}

     	# nothing to do if the open failed (we log the error later)

As shown in the context the intent of that code is not do die but to
log the error later.

Per my reading of the file this was the only thing autodie was doing
in this file (there was no other code it altered). So let's remove it,
both to fix the logic error and to get rid of the dependency.

61d48c66ea completion: correct zsh detection when run from git-completion.zsh
v2.18.0-rc0~90^2 (completion: reduce overhead of clearing cached
--options, 2018-04-18) worked around a bug in bash's "set" builtin on
MacOS by using compgen instead.  It was careful to avoid breaking zsh
by guarding this workaround with

	if [[ -n ${ZSH_VERSION-}} ]]

Alas, this interacts poorly with git-completion.zsh's bash emulation:

	ZSH_VERSION='' . "$script"

Correct it by instead using a new GIT_SOURCING_ZSH_COMPLETION shell
variable to detect whether git-completion.bash is being sourced from
git-completion.zsh.  This way, the zsh variant is used both when run
from zsh directly and when run via git-completion.zsh.

Reproduction recipe:

 1. cd git/contrib/completion && cp git-completion.zsh _git
 2. Put the following in a new ~/.zshrc file:

 	autoload -U compinit; compinit
	autoload -U bashcompinit; bashcompinit
	fpath=(~/src/git/contrib/completion $fpath)

 3. Open zsh and "git <TAB>".

With this patch:
Triggers nice git-completion.bash based tab completion

Without:
 contrib/completion/git-completion.bash:354: read-only variable: QISUFFIX
 zsh:12: command not found: ___main
 zsh:15: _default: function definition file not found

b221b5ab9b completion: collapse extra --no-.. options
The commands that make use of --git-completion-helper feature could
now produce a lot of --no-xxx options that a command can take. This in
many case could nearly double the amount of completable options, using
more screen estate and also harder to search for the wanted option.

This patch attempts to mitigate that by collapsing extra --no-
options, the ones that are added by --git-completion-helper and not in
original struct option arrays. The "--no-..." option will be displayed
in this case to hint about more options, e.g.

    > ~/w/git $ git clone --
    --bare                 --origin=
    --branch=              --progress
    --checkout             --quiet
    --config=              --recurse-submodules
    --depth=               --reference=
    --dissociate           --reference-if-able=
    --filter=              --separate-git-dir=
    --hardlinks            --shallow-exclude=
    --ipv4                 --shallow-since=
    --ipv6                 --shallow-submodules
    --jobs=                --shared
    --local                --single-branch
    --mirror               --tags
    --no-...               --template=
    --no-checkout          --upload-pack=
    --no-hardlinks         --verbose
    --no-tags

and when you complete it with --no-<tab>, all negative options will be
presented:

    > ~/w/git $ git clone --no-
    --no-bare                 --no-quiet
    --no-branch               --no-recurse-submodules
    --no-checkout             --no-reference
    --no-config               --no-reference-if-able
    --no-depth                --no-separate-git-dir
    --no-dissociate           --no-shallow-exclude
    --no-filter               --no-shallow-since
    --no-hardlinks            --no-shallow-submodules
    --no-ipv4                 --no-shared
    --no-ipv6                 --no-single-branch
    --no-jobs                 --no-tags
    --no-local                --no-template
    --no-mirror               --no-upload-pack
    --no-origin               --no-verbose
    --no-progress

Corner case: to make sure that people will never accidentally complete
the fake option "--no-..." there must be one real --no- in the first
complete listing even if it's not from the original struct option.

PS. This could could be made simpler with ";&" to fall through from
"--no-*" block and share the code but ";&" is not available on bash-3
(i.e. Mac)

f22f682695 completion: complete general config vars in two steps
There are 581 config variables as of now when you do "git config
<tab>" which can fill up a few screens and is not very helpful when
you have to look through columns of text to find what you want.

This patch instead shows you only first level when you do

    git config <tab>

There are 78 items, which use up 8 rows in my screen. Compared to
screens of text, it's pretty good. Once you have chosen you first
level, e.g. color:

    git config color.<tab>

will show you all color.*

This is not a new idea. branch.* and remote.* completion already does
this for second and third levels. For those variables, you'll need to
<tab> three times to get full variable name.

2b1c01d22e parse-options: option to let --git-completion-helper show negative form
When 7fb6aefd2a (Merge branch 'nd/parseopt-completion' - 2018-03-14)
is merged, the completion for negative form is left out because the
series is alread long and it could be done in a follow up series. This
is it.

--git-completion-helper now provides --no-xxx so that git-completion.bash
can drop the extra custom --no-xxx in the script. It adds a lot more
--no-xxx than what's current provided by the git-completion.bash
script. We'll trim that down later.

3301d36b29 completion: add and use --list-cmds=alias
By providing aliases via --list-cmds=, we could simplify command
collection code in the script. We only issue one git command. Before
this patch that is "git config", after it's "git --list-cmds=". In
"git help" completion case we actually reduce one "git" process (for
getting guides) but that call was added in this series so it does not
really count.

A couple of bash functions are removed because they are not needed
anymore. __git_compute_all_commands() and $__git_all_commands stay
because they are still needed for completing pager.* config and
without "alias" group, the result is still cacheable.

There is a slight (good) change in _git_help() with this patch: before
"git help <tab>" shows external commands (as in _not_ part of git) as
well as part of $__git_all_commands. We have finer control over
command listing now and can exclude that because we can't provide a
man page for external commands anyway.

84a9713106 completion: let git provide the completable command list
Instead of maintaining a separate list of command classification,
which often could go out of date, let's centralize the information
back in git.

While the function in git-completion.bash implies "list porcelain
commands", that's not exactly what it does. It gets all commands (aka
--list-cmds=main,others) then exclude certain non-porcelain ones. We
could almost recreate this list two lists list-mainporcelain and
others. The non-porcelain-but-included-anyway is added by the third
category list-complete.

Note that the current completion script incorrectly classifies
filter-branch as porcelain and t9902 tests this behavior. We keep it
this way in t9902 because this test does not really care which
particular command is porcelain or plumbing, they're just names.

8b4c2e0b1c completion: don't return with error from __gitcomp_file_direct()
In __gitcomp_file_direct() we tell Bash that it should handle our
possible completion words as filenames with the following piece of
cleverness:

  # use a hack to enable file mode in bash < 4
  compopt -o filenames +o nospace 2>/dev/null ||
  compgen -f /non-existing-dir/ > /dev/null

Unfortunately, this makes this function always return with error
when it is not invoked in real completion, but e.g. in tests of
't9902-completion.sh':

  - First the 'compopt' line errors out
    - either because in Bash v3.x there is no such command,
    - or because in Bash v4.x it complains about "not currently
      executing completion function",

  - then 'compgen' just silently returns with error because of the
    non-existing directory.

Since __gitcomp_file_direct() is now the last command executed in
__git_complete_index_file(), that function returns with error as well,
which prevents it from being invoked in tests directly as is, and
would require extra steps in test to hide its error code.

So let's make sure that __gitcomp_file_direct() doesn't return with
error, because in the tests coming in the following patch we do want
to exercise __git_complete_index_file() directly,

__gitcomp_file() contains the same construct, and thus it, too, always
returns with error.  Update that function accordingly as well.

While at it, also remove the space from between the redirection
operator and the filename in both functions.

085e2ee0e6 completion: load completion file for external subcommand
Adding external subcommands to Git is as easy as to put an executable
file git-foo into PATH. Packaging such subcommands for a Linux
distribution can be achieved by unpacking the executable into /usr/bin
of the user's system. Adding system-wide completion scripts for new
subcommands, however, can be a bit tricky.

Since bash-completion started to use dynamical loading of completion
scripts since v1.90 (preview of v2.0), it is no longer sufficient to
drop a completion script of a subcommand into the standard completions
path, /usr/share/bash-completion/completions, since this script will not
be loaded if called as a git subcommand.

For example, look at https://bugs.gentoo.org/544722. To give a short
summary: The popular git-flow subcommand provides a completion script,
which gets installed as /usr/share/bash-completion/completions/git-flow.

If you now type into a Bash shell:

    git flow <TAB>

You will not get any completions, because bash-completion only loads
completions for git and git has no idea that git-flow is defined in
another file. You have to load this script manually or trigger the
dynamic loader with:

    git-flow <TAB> # Please notice the dash instead of whitespace

This will not complete anything either, because it only defines a Bash
function, without generating completions. But now the correct completion
script has been loaded and the first command can use the completions.

So, the goal is now to teach the git completion script to consider the
possibility of external completion scripts for subcommands, but of
course without breaking current workflows.

I think the easiest method is to use a function that was defined by
bash-completion v1.90, namely _completion_loader. It will take care of
loading the correct script if present. Afterwards, the git completion
script behaves as usual.

_completion_loader was introduced in commit 20c05b43 of bash-completion
(https://github.com/scop/bash-completion.git) back in 2011, so it should
be available in even older LTS distributions. This function searches for
external completion scripts not only in the default path
/usr/share/bash-completion/completions, but also in the user's home
directory via $XDG_DATA_HOME and in a user specified directory via
$BASH_COMPLETION_USER_DIR.

The only "drawback" (if it even can be called as such) is, that if
_completion_loader does not find a completion script, it automatically
registers a minimal function for basic path completion. In practice,
however, this will not matter, because in this case the given command is
a git command in its dashed form, e.g. 'git-diff-index', and those have
been deprecated for a long time.

This way we can leverage bash-completion's dynamic loading for git
subcommands and make it easier for developers to distribute custom
completion scripts.

279ffad17d coccinelle: avoid wrong transformation suggestions from commit.cocci
The semantic patch 'contrib/coccinelle/commit.cocci' added in
2e27bd7731 (treewide: replace maybe_tree with accessor methods,
2018-04-06) is supposed to "ensure that all references to the
'maybe_tree' member of struct commit are either mutations or accesses
through get_commit_tree()".  So get_commit_tree() clearly must be able
to directly access the 'maybe_tree' member, and 'commit.cocci' has a
bit of a roundabout workaround to ensure that get_commit_tree()'s
direct access in its return statement is not transformed: after all
references to 'maybe_tree' have been transformed to a call to
get_commit_tree(), including the reference in get_commit_tree()
itself, the last rule transforms back a 'return get_commit_tree()'
statement, back then found only in get_commit_tree() itself, to a
direct access.

Unfortunately, already the very next commit shows that this workaround
is insufficient: 7b8a21dba1 (commit-graph: lazy-load trees for
commits, 2018-04-06) extends get_commit_tree() with a condition
directly accessing the 'maybe_tree' member, and Coccinelle with
'commit.cocci' promptly detects it and suggests a transformation to
avoid it.  This transformation is clearly wrong, because calling
get_commit_tree() to access 'maybe_tree' _in_ get_commit_tree() would
obviously lead to recursion.  Furthermore, the same commit added
another, more specialized getter function get_commit_tree_in_graph(),
whose legitimate direct access to 'maybe_tree' triggers a similar
wrong transformation suggestion.

Exclude both of these getter functions from the general rule in
'commit.cocci' that matches their direct accesses to 'maybe_tree'.
Also exclude load_tree_for_commit(), which, as static helper funcion
of get_commit_tree_in_graph(), has legitimate direct access to
'maybe_tree' as well.

The last rule transforming back 'return get_commit_tree()' statements
to direct accesses thus became unnecessary, remove it.

8f6aed71d2 rebase: introduce the --rebase-merges option
Once upon a time, this here developer thought: wouldn't it be nice if,
say, Git for Windows' patches on top of core Git could be represented as
a thicket of branches, and be rebased on top of core Git in order to
maintain a cherry-pick'able set of patch series?

The original attempt to answer this was: git rebase --preserve-merges.

However, that experiment was never intended as an interactive option,
and it only piggy-backed on git rebase --interactive because that
command's implementation looked already very, very familiar: it was
designed by the same person who designed --preserve-merges: yours truly.

Some time later, some other developer (I am looking at you, Andreas!
;-)) decided that it would be a good idea to allow --preserve-merges to
be combined with --interactive (with caveats!) and the Git maintainer
(well, the interim Git maintainer during Junio's absence, that is)
agreed, and that is when the glamor of the --preserve-merges design
started to fall apart rather quickly and unglamorously.

The reason? In --preserve-merges mode, the parents of a merge commit (or
for that matter, of *any* commit) were not stated explicitly, but were
*implied* by the commit name passed to the `pick` command.

This made it impossible, for example, to reorder commits. Not to mention
to move commits between branches or, deity forbid, to split topic branches
into two.

Alas, these shortcomings also prevented that mode (whose original
purpose was to serve Git for Windows' needs, with the additional hope
that it may be useful to others, too) from serving Git for Windows'
needs.

Five years later, when it became really untenable to have one unwieldy,
big hodge-podge patch series of partly related, partly unrelated patches
in Git for Windows that was rebased onto core Git's tags from time to
time (earning the undeserved wrath of the developer of the ill-fated
git-remote-hg series that first obsoleted Git for Windows' competing
approach, only to be abandoned without maintainer later) was really
untenable, the "Git garden shears" were born [*1*/*2*]: a script,
piggy-backing on top of the interactive rebase, that would first
determine the branch topology of the patches to be rebased, create a
pseudo todo list for further editing, transform the result into a real
todo list (making heavy use of the `exec` command to "implement" the
missing todo list commands) and finally recreate the patch series on
top of the new base commit.

That was in 2013. And it took about three weeks to come up with the
design and implement it as an out-of-tree script. Needless to say, the
implementation needed quite a few years to stabilize, all the while the
design itself proved itself sound.

With this patch, the goodness of the Git garden shears comes to `git
rebase -i` itself. Passing the `--rebase-merges` option will generate
a todo list that can be understood readily, and where it is obvious
how to reorder commits. New branches can be introduced by inserting
`label` commands and calling `merge <label>`. And once this mode will
have become stable and universally accepted, we can deprecate the design
mistake that was `--preserve-merges`.

df70b190bd completion: make stash -p and alias for stash push -p
We define 'git stash -p' as an alias for 'git stash push -p' in the
manpage.  Do the same in the completion script, so all options that
can be given to 'git stash push' are being completed when the user is
using 'git stash -p --<tab>'.  Currently the only additional option
the user will get is '--message', but there may be more in the future.

0eb5a4f911 completion: stop showing 'save' for stash by default
The 'save' subcommand in git stash has been deprecated in
fd2ebf14db ("stash: mark "git stash save" deprecated in the man page",
2017-10-22).

Stop showing it when the users enters 'git stash <tab>' or 'git stash
s<tab>'.  Keep showing it however when the user enters 'git stash sa<tab>'
or any more characters of the 'save' subcommand.  This is designed to
not encourage users to use 'git stash save', but still leaving the
completion option once it's clear that's what the user means.

94408dc71c completion: reduce overhead of clearing cached --options
To get the names of all '$__git_builtin_*' variables caching --options
of builtin commands in order to unset them, 8b0eaa41f2 (completion:
clear cached --options when sourcing the completion script,
2018-03-22) runs a 'set |sed s///' pipeline.  This works both in Bash
and in ZSH, but has a higher than necessary overhead with the extra
processes.

In Bash we can do better: run the 'compgen -v __gitcomp_builtin_'
builtin command, which lists the same variables, but without a
pipeline and 'sed' it can do so with lower overhead.
ZSH will still continue to run that pipeline.

This change also happens to work around an issue in the default Bash
version shipped in macOS (3.2.57), reported by users of the Powerline
shell prompt, which was triggered by the same commit 8b0eaa41f2 as
well.  Powerline uses several Unicode Private Use Area code points to
represent some of its pretty text UI elements (arrows and what not),
and these are stored in the $PS1 variable.  Apparently the 'set'
builtin of said Bash version on macOS has issues with these code
points, and produces garbled output where Powerline's special symbols
should be in the $PS1 variable.  This, in turn, triggers the following
error message in the downstream 'sed' process:

  sed: RE error: illegal byte sequence

Other Bash versions, notably 4.4.19 on macOS via homebrew (i.e. a
newer version on the same platform) and 3.2.25 on CentOS (i.e. a
slightly earlier version, though on a different platform) are not
affected.  ZSH in macOS (the versions shipped by default or installed
via homebrew) or on other platforms isn't affected either.

With this patch neither the 'set' builtin is invoked to print garbage,
nor 'sed' to choke on it.

7b00342068 completion: fill COMPREPLY directly when completing paths
During git-aware path completion, when a lot of path components have
to be listed, a significant amount of time is spent in
__gitcomp_file(), or more accurately in the shell loop of
__gitcompappend(), iterating over all the path components filtering
path components matching the current word to be completed, adding
prefix path components, and placing the resulting matching paths into
the COMPREPLY array.

Now, a previous patch in this series made 'git ls-files' and 'git
diff-index' list only paths matching the current word to be completed,
so an additional filtering in __gitcomp_file() is not necessary
anymore.  Adding the prefix path components could be done much more
efficiently in __git_index_files()'s 'awk' script while stripping
trailing path components and removing duplicates and quoting.  And
then the resulting paths won't require any more filtering or
processing before being handed over to Bash, so we could fill the
COMPREPLY array directly.

Unfortunately, we can't simply use the __gitcomp_direct() helper
function to do that, because __gitcomp_file() does one additional
thing: it tells Bash that we are doing filename completion, so the
shell will kindly do four important things for us:

  1. Append a trailing space to all filenames.
  2. Append a trailing '/' to all directory names.
  3. Escape any meta, globbing, separator, etc. characters.
  4. List only the current path component when listing possible
     completions (i.e. 'dir/subdir/f<TAB>' will list 'file1', 'file2',
     etc. instead of the whole 'dir/subdir/file1',
     'dir/subdir/file2').

While we could let __git_index_files()'s 'awk' script take care of the
first two points, the third one gets tricky, and we absolutely need
the shell's support for the fourth.

Add the helper function __gitcomp_file_direct(), which, just like
__gitcomp_direct(), fills the COMPREPLY array with prefiltered and
preprocessed paths without any additional processing, without a shell
loop, with just one single compound assignment, and, similar to
__gitcomp_file(), tells Bash and ZSH that we are doing filename
completion.  Extend __git_index_files()'s 'awk' script a bit to
prepend any prefix path components to all listed paths.  Finally,
modify __git_complete_index_file() to feed __git_index_files()'s
output to ___gitcomp_file_direct() instead of __gitcomp_file().

After this patch there is no shell loop left in the path completion
code path.

This speeds up path completion when there are a lot of paths matching
the current word to be completed.  In a pathological repository with
100k files in a single directory, listing all those files:

  Before this patch, best of five, using GNU awk on Linux:

    $ time cur=dir/ __git_complete_index_file

    real    0m0.983s
    user    0m1.004s
    sys     0m0.033s

  After:

    real    0m0.313s
    user    0m0.341s
    sys     0m0.029s

  Difference: -68.2%
  Speedup:      3.1x

  To see the benefits of the whole patch series, the same command with
  v2.17.0:

    real    0m2.736s
    user    0m2.472s
    sys     0m0.610s

  Difference: -88.6%
  Speedup:      8.7x

Note that this patch changes the output of the __git_index_files()
helper function by unconditionally prepending the prefix path
components to every listed path.  This would break users' completion
scriptlets that directly run:

  __gitcomp_file "$(__git_index_files ...)" "$pfx" "$cur_"

because that would add the prefix path components once more.
However, __git_index_files() is kind of a "helper function of a helper
function", and users' completion scriptlets should have been using
__git_complete_index_file() for git-aware path completion in the first
place, so this is likely doesn't worth worrying about.

193757f806 completion: improve handling quoted paths in 'git ls-files's output
If any pathname contains backslash, double quote, tab, newline, or any
control characters, 'git ls-files' and 'git diff-index' will enclose
that pathname in double quotes and escape those special characters
using C-style one-character escape sequences or \nnn octal values.
This prevents those files from being listed during git-aware path
completion, because due to the quoting they will never match the
current word to be completed.

Extend __git_index_files()'s 'awk' script to remove all that quoting
and escaping from unique path components, so even paths containing
(almost all) such special characters can be completed.

Paths containing newline characters are still an issue, though.  We
use newlines as separator character when filling the COMPREPLY array,
so a path with one or more newline will end up split to two or more
elements in COMPREPLY, basically breaking completion.  There is
nothing we can do about it without a significant performance hit, so
let's just ignore such paths for now.  As far as paths with newlines
are concerned, this isn't any different from the previous behavior,
because those paths were always omitted, though in the past they were
omitted because due to the quoting they didn't match the current word
to be completed.  Anyway, Bash's own filename completion (Meta-/) can
complete even those paths, if need be.

Note:

  - We don't dequote path components right away as they are coming in,
    because then we would have to dequote each directory name
    repeatedly, as many times as it appears in the input, i.e. as many
    times as the number of listed paths it contains.  Instead, we
    dequote them at the end, as we print unique path components.

  - Even when a directory name itself does not contain any special
    characters, it will still be quoted if any of its trailing path
    components do.  If a directory contains paths both with and
    without special characters, then the name of that directory will
    appear both quoted and unquoted in the output of 'git ls-files'
    and 'git diff-index'.  Consequently, we will add such a directory
    name to the deduplicating associative array twice: once quoted and
    once unquoted.

    This means that we have to be careful after dequoting a directory
    name, and only print it if we haven't seen the same directory name
    unquoted.

  - It would be wonderful if we could just pass '-z' to those git
    commands to output \0-separated unquoted paths, and use \0 as
    record separator in the 'awk' script processing their output...
    this patch would be so much simpler, almost trivial even.
    Unfortunately, however, POSIX and most 'awk' implementations don't
    support \0 as record separator (GNU awk does support it).

  - This patch makes the earlier change to list paths with
    'core.quotePath=false' basically redundant, because this could
    decode any \nnn-escaped non-ASCII character just fine, as well.
    However, I suspect that 'git ls-files' can deal with those
    non-ASCII characters faster than this updated 'awk' script; just
    in case someone is burdened with tons of pathnames containing
    non-ASCII characters.

c1bc0a0e92 completion: remove repeated dirnames with 'awk' during path completion
During git-aware path completion, after all the trailing path
components have been removed from the output of 'git ls-files' and
'git diff-index' (see previous patch), each directory name is repeated
as many times as the number of listed paths it contains.  This can be
a lot of repetitions, especially when invoking path completion close
to the root of a big worktree, which would cause a considerable
overhead downstream of __git_index_files(), in particular in the shell
loop that fills the COMPREPLY array.  To reduce this overhead,
__git_index_files() runs the classic '... |sort |uniq' pattern to
remove those repetitions from the function's output.

While removing repeated directory names is effective in reducing the
number of iterations in that shell loop, it still imposes the overhead
of fork()+exec()ing two external processes, and two additional stages
in the pipeline, where potentially relatively large amount of data can
be passed between two subsequent pipeline stages.

Extend __git_index_files()'s 'awk' script to remove repeated path
components by first creating and filling an associative array indexed
by all encountered path components (after the trailing path components
have been removed), and then iterating over this array and printing
the indices, i.e. unique path components.  This way we can remove the
'|sort |uniq' pipeline stages, and their eliminated overhead results
in faster path completion.

Listing all tracked files (12) and directories (23) at the top of the
worktree in linux.git (over 62k files), i.e. what's doing all the hard
work behind 'git rm <TAB>':

  Before this patch, best of five, using GNU awk on Linux:

    real    0m0.069s
    user    0m0.089s
    sys     0m0.026s

  After:

    real    0m0.052s
    user    0m0.072s
    sys     0m0.014s

  Difference: -24.6%

Note that this changes order of elements in __git_index_files()'s
output.  This is not an issue, because this function was only ever
intended to feed paths into the COMPREPLY array, and Bash will sort
its elements (according to the users locale) anyway.

Note also that using 'awk' to remove repeated path components is also
beneficial for the performance of the next two patches:

  - The first will extend this 'awk' script to dequote quoted paths in
    the output of 'git ls-files' and 'git diff-index'.  With this
    patch it will only have to dequote unique path components, not
    all.

  - The second will, among other things, extend this 'awk' script to
    prepend prefix path components from the command line to the
    currently completed path component.  Consequently, each line in
    'awk's output will grow longer.  Without this patch that '|sort
    |uniq' would have to exchange and process that much more data.

105c0efff3 completion: use 'awk' to strip trailing path components
During git-aware path completion we complete one path component at a
time, i.e. 'git add <TAB>' offers only 'dir/' at first, not
'dir/subdir/file' right away, just like Bash's own filename
completion.  However, since both 'git ls-files' and 'git diff-index'
dive deep into subdirectories, we have to strip all trailing path
components from the listed paths, keeping only the leading path
component.  This stripping is currently done in a shell loop in
__git_index_files(), which can take a significant amount of time when
it has to iterate through a large number of paths.

Replace this shell loop with a little 'awk' script using '/' as input
field separator and printing the first field, which produces the same
output much faster.

Listing all tracked files (12) and directories (23) at the top of the
worktree in linux.git (over 62k files), i.e. what's doing all the hard
work behind 'git rm <TAB>':

  Before this patch, best of five, using GNU awk on Linux:

    $ time cur= __git_complete_index_file

    real    0m2.149s

  After:

    real    0m0.067s
    user    0m0.089s
    sys     0m0.023s

  Difference: -96.9%
  Speedup:     32.1x

Note that this could be done with 'sed', or even with 'cut', just as
well, but the upcoming patches require 'awk's scriptability.

Note also that this change means one more fork()+exec()ed process
during path completion, adding more overhead especially on Windows,
but a later patch will more than make up for it by eliminating two
other processes in the same function.

a364e984d1 completion: let 'ls-files' and 'diff-index' filter matching paths
During git-aware path completion, e.g. 'git rm dir/fil<TAB>', both
'git ls-files' and 'git diff-index' list all paths in the given 'dir/'
matching certain criteria (cached, modified, untracked, etc.)
appropriate for the given git command, even paths whose names don't
begin with 'fil'.  This comes with a considerable performance
penalty when the directory in question contains a lot of paths, but
the current word can be uniquely completed or when only a handful of
those paths match the current word.

Reduce the number of iterations in this codepath from the number of
paths to the number of matching paths by specifying an appropriate
globbing pattern to 'git ls-files' and 'git diff-index' to list only
paths that match the current word to be completed.

Note that both commands treat backslashes as escape characters in
their file arguments, e.g. to preserve the literal meaning of globbing
characters, so we have to double every backslash in the globbing
pattern.  This is why one of the path completion tests specifically
checks the completion of a path containing a literal backslash
character (that test still fails, though, because both commands output
such paths enclosed in double quotes and the special characters
escaped; a later patch in this series will deal with those).

This speeds up path completion considerably when there are a lot of
non-matching paths to be filtered out.  Uniquely completing a tracked
filename at the top of the worktree in linux.git (over 62k files),
i.e. what's doing all the hard work behind 'git rm Mak<TAB>' to
complete 'Makefile':

f12785a3a7 completion: improve handling quoted paths on the command line
Our git-aware path completion doesn't work when it has to complete a
word already containing quoted and/or backslash-escaped characters on
the command line.  The root cause of the issue is that completion
functions see all words on the command line verbatim, i.e. including
all backslash, single and double quote characters that the shell would
eventually remove when executing the finished command.  These
quoting/escaping characters cause different issues depending on which
path component of the word to be completed contains them:

  - The quoting/escaping is in the prefix path component(s).

    Let's suppose we have a directory called 'New Dir', containing two
    untracked files 'file.c' and 'file.o', and we have a gitignore
    rule ignoring object files.  In this case all of these:

      git add New\ Dir/<TAB>
      git add "New Dir/<TAB>
      git add 'New Dir/<TAB>

    should uniquely complete 'file.c' right away, but Bash offers both
    'file.c' and 'file.o' instead.  The reason for this behavior is
    that our completion script uses the prefix directory name like
    'git -C "New\ Dir/" ls-files ...", i.e. with the backslash inside
    double quotes.  Git then tries to enter a directory called
    'New\ Dir', which (most likely) fails because such a directory
    doesn't exists.  As a result our completion script doesn't list
    any files, leaves the COMPREPLY array empty, which in turn causes
    Bash to fall back to its simple filename completion and lists all
    files in that directory, i.e. both 'file.c' and 'file.o'.

  - The quoting/escaping is in the path component to be completed.

    Let's suppose we have two untracked files 'New File.c' and
    'New File.o', and we have a gitignore rule ignoring object files.
    In this case all of these:

      git add New\ Fi<TAB>
      git add "New Fi<TAB>
      git add 'New Fi<TAB>

    should uniquely complete 'New File.c' right away, but Bash offers
    both 'New File.c' and 'New File.o' instead.  The reason for this
    behavior is that our completion script uses this 'New\ Fi' or
    '"New Fi' etc. word to filter matching paths, and of course none
    of the potential filenames will match because of the included
    backslash or double quote.  The end result is the same as above:
    the completion script doesn't list any files, Bash falls back to
    its filename completion, which then lists the matching object file
    as well.

Add the new helper function __git_dequote() [1], which removes (most
of[2]) the quoting and escaping from the word it gets as argument.  To
minimize the overhead of calling this function, store its result in
the variable $dequoted_word, supposed to be declared local in the
caller; simply printing the result would require a command
substitution imposing the overhead of fork()ing a subshell.  Use this
function in __git_complete_index_file() to dequote the current word,
i.e. the path, to be completed, to avoid the above described
quoting-related issues, thereby fixing two of the failing quoted path
completion tests.

[1] The bash-completion project already has a dequote() function,
    which I hoped I could borrow to deal with this, but unfortunately
    it doesn't work quite well for this purpose (perhaps that's why
    even the bash-completion project only rarely uses it).  The main
    issue is that their dequote() is implemented as:

      eval printf %s "$1" 2> /dev/null

    where $1 would contain the word to be completed.  While it's a
    short and sweet one-liner, the use of 'eval' requires that $1 is a
    syntactically valid string, which is not the case when quoting the
    path like 'git add "New Dir/<TAB>'.  This causes 'eval' to fail,
    because it can't find the matching closing double quote, and the
    function returns nothing.  The result is totally broken behavior,
    as if the current word were empty, and the completion script would
    then list all files from the current directory.  This is why one
    of the quoted path completion tests specifically checks the
    completion of a path with an opening but without a corresponding
    closing double quote character.  Furthermore, the 'eval' performs
    all kinds of expansions, which may or may not be desired; I think
    it's the latter.  Finally, using this function would require a
    command substitution.

[2] Bash understands the $'string' quoting as well, which "expands to
    'string', with backslash-escaped characters replaced as specified
    by the ANSI C standard" (quoted from Bash manpage).  Since shell
    metacharacters, field separators, globbing, etc. can all be easily
    entered using standard shell escaping or quoting, this type of
    quoting comes in handly when dealing with control characters that
    are otherwise difficult both to "type" and to see on the command
    line.  Because of this difficulty I would assume that people do
    avoid pathnames with such control characters anyway, so I didn't
    bother implementing it.  This function is already way too long as
    it is.

3dfe23ba51 completion: support completing non-ASCII pathnames
Unless the user has 'core.quotePath=false' somewhere in the
configuration, both 'git ls-files' and 'git diff-index' will by
default quote any pathnames that contain bytes with values higher than
0x80, and escape those bytes as '\nnn' octal values.  This prevents
completing paths when the current path component to be completed
contains any non-ASCII, most notably UTF-8, characters, because none
of the listed quoted paths will match the current word on the command
line.

Set 'core.quotePath=false' for those 'git ls-files' and 'git
diff-index' invocations, so they won't consider bytes higher than 0x80
as "unusual", and won't quote pathnames containing such characters.

Note that pathnames containing backslash, double quote, or control
characters will still be quoted; a later patch in this series will
deal with those.

them.

6d5ed4836d git{,-blame}.el: remove old bitrotting Emacs code
The git-blame.el mode has been superseded by Emacs's own
vc-annotate (invoked by C-x v g). Users of the git.el mode are now
much better off using either Magit or the Git backend for Emacs's own
VC mode.

These modes were added over 10 years ago when Emacs's own Git support
was much less mature, and there weren't other mature modes in the wild
or shipped with Emacs itself.

These days these modes have few if any users, and users of git aren't
well served by us shipping these (some OS's install them alongside git
by default, which is confusing and leads users astray).

So let's remove these per Alexandre Julliard's message to the
ML[1]. If someone still wants these for some reason they're better
served by hosting these elsewhere (e.g. on ELPA), instead of us
distributing them with git.

However, since downstream packagers such as Debian are packaging this
as git-el it's less disruptive to still carry these files as Elisp
code that'll error out with a message suggesting alternatives, rather
than drop the files entirely[2].

Then rather than receive a cryptic load error when they upgrade
existing users will get an error directing them to the README file, or
to just stop requiring these modes. I think it makes sense to link to
GitHub's hosting of contrib/emacs/README (which'll be updated by the
time users see this) so they don't have to hunt down the packaged
README on their local system.

78a2d21231 completion: improve ls-files filter performance
From the output of ls-files, we remove all but the leftmost path
component and then we eliminate duplicates. We do this in a while loop,
which is a performance bottleneck when the number of iterations is large
(e.g. for 60000 files in linux.git).

$ COMP_WORDS=(git status -- ar) COMP_CWORD=3; time _git

real    0m11.876s
user    0m4.685s
sys     0m6.808s

Replacing the loop with the cut command improves performance
significantly:

$ COMP_WORDS=(git status -- ar) COMP_CWORD=3; time _git

real    0m1.372s
user    0m0.263s
sys     0m0.167s

The measurements were done with Msys2 bash, which is used by Git for
Windows.

When filtering the ls-files output we take care not to touch absolute
paths. This is redundant, because ls-files will never output absolute
paths. Remove the unnecessary operations.

The issue was reported here:

8b0eaa41f2 completion: clear cached --options when sourcing the completion script
The established way to update the completion script in an already
running shell is to simply source it again: this brings in any new
--options and features, and clears caching variables.  E.g. it clears
the variables caching the list of (all|porcelain) git commands, so
when they are later lazy-initialized again, then they will list and
cache any newly installed commmands as well.

Unfortunately, since d401f3debc (git-completion.bash: introduce
__gitcomp_builtin, 2018-02-09) and subsequent patches this doesn't
work for a lot of git commands' options.  To eliminate a lot of
hard-to-maintain hard-coded lists of options, those commits changed
the completion script to use a bunch of programmatically created and
lazy-initialized variables to cache the options of those builtin
porcelain commands that use parse-options.  These variables are not
cleared upon sourcing the completion script, therefore they continue
caching the old lists of options, even when some commands recently
learned new options or when deprecated options were removed.

Always 'unset' these variables caching the options of builtin commands
when sourcing the completion script.

Redirect 'unset's stderr to /dev/null, because ZSH's 'unset' complains
if it's invoked without any arguments, i.e. no variables caching
builtin's options are set.  This can happen, if someone were to source
the completion script twice without completing any --options in
between.  Bash stays silent in this case.

Add tests to ensure that these variables are indeed cleared when the
completion script is sourced; not just the variables caching options,
but all other caching variables, i.e. the variables caching commands,
porcelain commands and merge strategies as well.

4551fbba14 diff-highlight: detect --graph by indent
This patch fixes a corner case where diff-highlight may
scramble some diffs when combined with --graph.

Commit 7e4ffb4c17 (diff-highlight: add support for --graph
output, 2016-08-29) taught diff-highlight to skip past the
graph characters at the start of each line with this regex:

  ($COLOR?\|$COLOR?\s+)*

I.e., any series of pipes separated by and followed by
arbitrary whitespace.  We need to match more than just a
single space because the commit in question may be indented
to accommodate other parts of the graph drawing. E.g.:

 * commit 1234abcd
 | ...
 | diff --git ...

has only a single space, but for the last commit before a
fork:

 | | |
 | * | commit 1234abcd
 | |/  ...
 | |   diff --git

the diff lines have more spaces between the pipes and the
start of the diff.

However, when we soak up all of those spaces with the
$GRAPH regex, we may accidentally include the leading space
for a context line. That means we may consider the actual
contents of a context line as part of the diff syntax. In
other words, something like this:

   normal context line
  -old line
  +new line
   -this is a context line with a leading dash

would cause us to see that final context line as a removal
line, and we'd end up showing the hunk in the wrong order:

  normal context line
  -old line
   -this is a context line with a leading dash
  +new line

Instead, let's a be a little more clever about parsing the
graph. We'll look for the actual "*" line that marks the
start of a commit, and record the indentation we see there.
Then we can skip past that indentation when checking whether
the line is a hunk header, removal, addition, etc.

There is one tricky thing: the indentation in bytes may be
different for various lines of the graph due to coloring.
E.g., the "*" on a commit line is generally shown without
color, but on the actual diff lines, it will be replaced
with a colorized "|" character, adding several bytes. We
work around this here by counting "visible" bytes. This is
unfortunately a bit more expensive, making us about twice as
slow to handle --graph output. But since this is meant to be
used interactively anyway, it's tolerably fast (and the
non-graph case is unaffected).

One alternative would be to search for hunk header lines and
use their indentation (since they'd have the same colors as
the diff lines which follow). But that just opens up
different corner cases. If we see:

  | |    @@ 1,2 1,3 @@

we cannot know if this is a real diff that has been
indented due to the graph, or if it's a context line that
happens to look like a diff header. We can only be sure of
the indent on the "*" lines, since we know those don't
contain arbitrary data (technically the user could include a
bunch of extra indentation via --format, but that's rare
enough to disregard).

Our tests send git's output directly to files or pipes, so
there will never be any color. Let's do at least one --color
test to make sure that we can handle this case (which we
currently can, but will be an easy thing to mess up when we
touch the graph code in a future patch).

We'll just cover the --graph case, since this is much more
complex than the earlier cases (i.e., if it manages to
highlight, then the non-graph case definitely would).

7ce2f4ca0e diff-highlight: test interleaved parallel lines of history
The graph test in t9400 covers the case of two simultaneous
branches, but all of the commits during this time are on the
right-hand branch. So we test a graph structure like:

  | |
  | * commit ...
  | |

but we never see the reverse, a commit on the left-hand
branch:

  | |
  * | commit ...
  | |

Since this is an easy thing to get wrong when touching the
graph-matching code, let's cover it by adding one more
commit with its timestamp interleaved with the other branch.

Note that we need to pass --date-order to convince Git to
show it this way (since --topo-order tries to keep lines of
history separate).

subject to how long the test script takes to run).

Let's use test_tick to make sure this is stable. Note that
we actually have to rearrange the order of the branches to
match the expected graph structure (which means that
previously we might racily have been testing a slightly
different output, though the test is written in such a way
that we'd still pass).

let git-completion.bash do the suppressing if needed).

This makes --rerere-autoupdate completable for am, cherry-pick and
revert. rebase completion is fixed manually because it's a shell
script and does not benefit from --git-completion-helper.

common group email address. But every individual may want to receive
replies to her own personal address. That's what we have 'Reply-To'

28654678cf perl: move CPAN loader wrappers to another namespace
Move the Git::Error and Git::Mail::Address wrappers to the
Git::LoadCPAN::Loader::* namespace, e.g. Git::LoadCPAN::Error. That
module will then either load Error from CPAN (if installed on the OS),
or use Git::FromCPAN::Error.

When I added the Error wrapper in 20d2a30f8f ("Makefile: replace
perl/Makefile.PL with simple make rules", 2017-12-10) I didn't think
about how confusing it would be to have these modules sitting in the
same tree as our normal modules. Let's put these all into
Git::{Load,From}CPAN::* to clearly distinguish them from the rest.

This also makes things a bit less confusing since there was already a
Git::Error namespace ever since 8b9150e3e3 ("Git.pm: Handle failed
commands' output", 2006-06-24).

Desktops and servers tend to have no power sensor, thus on_ac_power returns
255 ("unknown").  Thus, let's take any answer other than 1 ("battery") as
no contraindication to run gc.

If that tool returns "unknown", there's no point in querying other sources
as it already queried them, and is smarter than us (can handle multiple
adapters).

a40e06ee33 perl: call timegm and timelocal with 4-digit year
Amazingly, timegm(gmtime(0)) is only 0 before 2020 because perl's
timegm deviates from GNU timegm(3) in how it handles years.

man Time::Local says

 Whenever possible, use an absolute four digit year instead.

with a detailed explanation about ambiguity of 2-digit years above that.

Even though this ambiguity is error-prone with >50% of users getting it
wrong, it has been like this for 20+ years, so we just use 4-digit years
everywhere to be on the safe side.

We add some extra logic to cvsimport because it allows 2-digit year
input and interpreting an 18 as 1918 can be avoided easily and safely.

8841b5222c subtree: fix add and pull for GPG-signed commits
If log.showsignature is true (or --show-signature is passed) while
performing a `subtree add` or `subtree pull`, the command fails.

toptree_for_commit() calls `log` and passes the output to `commit-tree`.
If this output shows the GPG signature data, `commit-tree` throws a
fatal error.

This commit fixes the issue by adding --no-show-signature to `log` calls
in a few places, as well as using the more appropriate `rev-parse`
instead where possible.

fbd7a23237 rebase: introduce and use pseudo-ref REBASE_HEAD
The new command `git rebase --show-current-patch` is useful for seeing
the commit related to the current rebase state. Some however may find
the "git show" command behind it too limiting. You may want to
increase context lines, do a diff that ignores whitespaces...

For these advanced use cases, the user can execute any command they
want with the new pseudo ref REBASE_HEAD.

This also helps show where the stopped commit is from, which is hard
to see from the previous patch which implements --show-current-patch.

cc73385cf6 worktree remove: new command
This command allows to delete a worktree. Like 'move' you cannot
remove the main worktree, or one with submodules inside [1].

For deleting $GIT_WORK_TREE, Untracked files or any staged entries are
considered precious and therefore prevent removal by default. Ignored
files are not precious.

When it comes to deleting $GIT_DIR, there's no "clean" check because
there should not be any valuable data in there, except:

- HEAD reflog. There is nothing we can do about this until somebody
  steps up and implements the ref graveyard.

- Detached HEAD. Technically it can still be recovered. Although it
  may be nice to warn about orphan commits like 'git checkout' does.

[1] We do 'git status' with --ignore-submodules=all for safety
    anyway. But this needs a closer look by submodule people before we
    can allow deletion. For example, if a submodule is totally clean,
    but its repo not absorbed to the main .git dir, then deleting
    worktree also deletes the valuable .submodule repo too.

9f792bb472 worktree move: new command
This command allows to relocate linked worktrees. Main worktree cannot
(yet) be moved.

There are two options to move the main worktree, but both have
complications, so it's not implemented yet. Anyway the options are:

- convert the main worktree to a linked one and move it away, leave
  the git repository where it is. The repo essentially becomes bare
  after this move.

- move the repository with the main worktree. The tricky part is make
  sure all file descriptors to the repository are closed, or it may
  fail on Windows.

97716d217c fetch: add a --prune-tags option and fetch.pruneTags config
Add a --prune-tags option to git-fetch, along with fetch.pruneTags
config option and a -P shorthand (-p is --prune). This allows for
doing any of:

    git fetch -p -P
    git fetch --prune --prune-tags
    git fetch -p -P origin
    git fetch --prune --prune-tags origin

Or simply:

    git config fetch.prune true &&
    git config fetch.pruneTags true &&
    git fetch

Instead of the much more verbose:

    git fetch --prune origin 'refs/tags/*:refs/tags/*' '+refs/heads/*:refs/remotes/origin/*'

Before this feature it was painful to support the use-case of pulling
from a repo which is having both its branches *and* tags deleted
regularly, and have our local references to reflect upstream.

At work we create deployment tags in the repo for each rollout, and
there's *lots* of those, so they're archived within weeks for
performance reasons.

Without this change it's hard to centrally configure such repos in
/etc/gitconfig (on servers that are only used for working with
them). You need to set fetch.prune=true globally, and then for each
repo:

    git -C {} config --replace-all remote.origin.fetch "refs/tags/*:refs/tags/*" "^\+*refs/tags/\*:refs/tags/\*$"

Now I can simply set fetch.pruneTags=true in /etc/gitconfig as well,
and users running "git pull" will automatically get the pruning
semantics I want.

Even though "git remote" has corresponding "prune" and "update
--prune" subcommands I'm intentionally not adding a corresponding
prune-tags or "update --prune --prune-tags" mode to that command.

It's advertised (as noted in my recent "git remote doc: correct
dangerous lies about what prune does") as only modifying remote
tracking references, whereas any --prune-tags option is always going
to modify what from the user's perspective is a local copy of the tag,
since there's no such thing as a remote tracking tag.

Ideally add_prune_tags_to_fetch_refspec() would be something that
would use ALLOC_GROW() to grow the 'fetch` member of the 'remote'
struct. Instead I'm realloc-ing remote->fetch and adding the
tag_refspec to the end.

The reason is that parse_{fetch,push}_refspec which allocate the
refspec (ultimately remote->fetch) struct are called many places that
don't have access to a 'remote' struct. It would be hard to change all
their callsites to be amenable to carry around the bookkeeping
variables required for dynamic allocation.

All the other callers of the API first incrementally construct the
string version of the refspec in remote->fetch_refspec via
add_fetch_refspec(), before finally calling parse_fetch_refspec() via
some variation of remote_get().

It's less of a pain to deal with the one special case that needs to
modify already constructed refspecs than to chase down and change all
the other callsites. The API I'm adding is intentionally not
generalized because if we add more of these we'd probably want to
re-visit how this is done.

See my "Re: [BUG] git remote prune removes local tags, depending on
fetch config" (87po6ahx87.fsf@evledraar.gmail.com;
https://public-inbox.org/git/87po6ahx87.fsf@evledraar.gmail.com/) for

d401f3debc git-completion.bash: introduce __gitcomp_builtin
This is a __gitcomp wrapper that will execute

    git ... --git-completion-helper

to get the list of completable options. The call will be made only
once and cached to avoid performance issues, especially on Windows.

__gitcomp_builtin() allows callers to change its output a bit by adding
some more options, or removing some.

- Current --git-completion-helper for example does not output --no-foo
  form, this has to be added manually by __gitcomp_builtin() callers
  when necessary

- Some options from --git-completion-helper should only be available in
  certain conditions (e.g. --continue and friends). __gitcomp_builtin()
  callers can remove them if the conditions are not met.

cd9a4b6d93 cocci: use format keyword instead of a literal string
There's a rule in strbuf.cocci for converting trivial uses of
strbuf_addf() to strbuf_addstr() in order to simplify the code and
improve performance a bit.  Coccinelle 1.0.0~rc19.deb-3 on Travis CI
lets the "%s" in that rule match format strings like "%d" as well for
some reason, though, leading to invalid proposed patches.

Use the "format" keyword to let Coccinelle parse the format string and
match the conversion specifier with a trivial regular expression
instead.  This works fine with both Coccinelle 1.0.0~rc19.deb-3 and
1.0.4.deb-3+b3 (the current version on Debian testing).

20d2a30f8f Makefile: replace perl/Makefile.PL with simple make rules
Replace the perl/Makefile.PL and the fallback perl/Makefile used under
NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily
inspired by how the i18n infrastructure's build process works[1].

The reason for having the Makefile.PL in the first place is that it
was initially[2] building a perl C binding to interface with libgit,
this functionality, that was removed[3] before Git.pm ever made it to
the master branch.

We've since since started maintaining a fallback perl/Makefile, as
MakeMaker wouldn't work on some platforms[4]. That's just the tip of
the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to
detect whether we need to regenerate the perl/perl.mak, which I fixed
just recently to deal with issues like the perl version changing from
under us[6].

There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on
the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as
pod2man-ing Git.pm & friends.

So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)
command instead of msgfmt. As that's being done rename the files
from *.pm to *.pmc just to indicate that they're generated (see
"perldoc -f require").

While I'm at it, change the fallback for Error.pm from being something
where we'll ship our own Error.pm if one doesn't exist at build time
to one where we just use a Git::Error wrapper that'll always prefer
the system-wide Error.pm, only falling back to our own copy if it
really doesn't exist at runtime. It's now shipped as
Git::FromCPAN::Error, making it easy to add other modules to
Git::FromCPAN::* in the future if that's needed.

Functional changes:

 * This will not always install into perl's idea of its global
   "installsitelib". This only potentially matters for packagers that
   need to expose Git.pm for non-git use, and as explained in the
   INSTALL file there's a trivial workaround.

 * The scripts themselves will 'use lib' the target directory, but if
   INSTLIBDIR is set it overrides it. It doesn't have to be this way,
   it could be set in addition to INSTLIBDIR, but my reading of [7] is
   that this is the desired behavior.

 * We don't build man pages for all of the perl modules as we used to,
   only Git(3pm). As discussed on-list[8] that we were building
   installed manpages for purely internal APIs like Git::I18N or
   private-Error.pm was always a bug anyway, and all the Git::SVN::*
   ones say they're internal APIs.

   There are apparently external users of Git.pm, but I don't expect
   there to be any of the others.

   As a side-effect of these general changes the perl documentation
   now only installed by install-{doc,man}, not a mere "install" as
   before.

041fe8fc83 git-prompt: fix reading files with windows line endings
If any of the files read by __git_eread have \r\n line endings, read
will only strip \n, leaving \r. This results in an ugly prompt, where
instead of

    user@pc MINGW64 /path/to/repo (BARE:master)

the last parenthesis is printed over the beginning of the prompt like

    )ser@pc MINGW64 /path/to/repo (BARE:master

This patch fixes the issue by changing the internal field separator
variable IFS to $'\r\n' before using the read builtin command.

Note that ANSI-C Quoting/POSIX Quoting ($'...') is supported by bash
as well as zsh, which are the current targets of git-prompt, cf.
contrib/completion/git-prompt.sh.
