fffd0cf520 completion: don't override given stash subcommand with -p
df70b190 (completion: make stash -p and alias for stash push -p,
2018-04-20) wanted to make sure "git stash -p <TAB>" offers the same
completion as "git stash push -p <TAB>", but it did so by forcing the
$subcommand to be "push" whenever then "-p" option is found on the
command line.

This harms any subcommand that can take the "-p" option---even when the
subcommand is explicitly given, e.g. "git stash show -p", the code added
by the change would overwrite the $subcommand the user gave us.

Fix it by making sure that the defaulting to "push" happens only when
there is no $subcommand given yet.

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.

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".

7d5ecd775d completion: list paths and refs for 'git worktree add'
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.

d447fe2bfe completion: clean up the __git_find_on_cmdline() helper function
The __git_find_on_cmdline() helper function started its life as
__git_find_subcommand() [1], but it served a more general purpose than
looking for subcommands, so later it was renamed accordingly [2].
However, that rename didn't touch the body of the function, and left
the $subcommand local variable behind, still reminiscent of the
function's original purpose.

Let's clean up the names of __git_find_on_cmdline()'s local variables
and get rid of that $subcommand variable name.

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.

c1ce9c06d0 completion: learn to complete git rebase --onto=
In 2b9bd488ae ("completion: teach rebase to use __gitcomp_builtin",
2019-09-12), the completion script learned to complete rebase using
__gitcomp_builtin(). However, this resulted in `--onto=` being suggested
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
fix this regression.

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

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
--config <TAB>', because we have to deal with that '--config=' being
part of the current word to be completed.

Add an option to the __git_complete_config_variable_name_and_value()
and in turn to the __git_complete_config_variable_name() helper
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
thus no further changes were necessary to complete possible values
after 'git clone --config=section.name=<TAB>'.

The previous commits taught the completion script how to complete

variables and values in the same 'section.name=value' form.

Note that handling the struck argument for 'git clone --config=<TAB>'

e1e00089da completion: complete configuration sections and variable names for 'git -c'
'git config' expects a configuration variable's name and value in
separate arguments, so we let the __gitcomp() helper append a space
character to each variable name by default, like we do for most other
things (--options, refs, paths, etc.).  'git -c', however, expects
them in a single option joined by a '=' character, i.e.
'section.name=value', so we should append a '=' character to each
fully completed variable name, but no space, so the user can continue
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
append that '=' character to configuration variables.  Update the
__gitcomp() helper function to not append a trailing space to any
completion words ending with a '=', not just to those option with a
stuck argument.

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.

The completion script runs the classic '| sort | uniq' pipeline to

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
    'color.something' is introduced which doesn't accept the same set
    of values.  We'll see which one happens first...

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.

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.
