When displaying the only hunk in a file's diff, the prompt already

This command is actually very similar to the 'd' ("do not stage this
hunk or any of the later hunks in the file") command: it just does

This patch implements the hunk searching feature in the C version of
`git add -p`.
A test is added to verify that this behavior matches the one of the Perl
version of `git add -p`.
Note that this involves a change of behavior: the Perl version uses (of
course) the Perl flavor of regular expressions, while this patch uses
the regcomp()/regexec(), i.e. POSIX extended regular expressions. In
practice, this behavior change is unlikely to matter.

Just like `git add --edit` allows the user to edit the diff before it is
being applied to the index, this feature allows the user to edit the
diff *hunk*.
Naturally, it gets a bit more complicated here because the result has
to play well with the remaining hunks of the overall diff. Therefore,
we have to do a loop in which we let the user edit the hunk, then test
whether the result would work, and if not, drop the edits and let the
user decide whether to try editing the hunk again.
Note: in contrast to the Perl version, we use the same diff
"coalescing" (i.e. merging overlapping hunks into a single one) also for
the check after editing, and we introduce a new flag for that purpose
that asks the `reassemble_patch()` function to pretend that all hunks
were selected for use.
This allows us to continue to run `git apply` *without* the
`--allow-overlap` option (unlike the Perl version), and it also fixes
two known breakages in `t3701-add-interactive.sh` (which we cannot mark
as resolved so far because the Perl script version is still the default
and continues to have those breakages).

This helper supports the scenario where Git has a populated `strbuf` and
wants to let the user edit it interactively.
In `git add -p`, we will use this to allow interactive hunk editing: the
diff hunks are already in memory, but we need to write them out to a
file so that an editor can be launched, then read everything back once
the user is done editing.

This is considered "the right thing to do", according to 933e44d3a0
("add -p": work-around an old laziness that does not coalesce hunks,
2011-04-06).
Note: we cannot simply modify the hunks while merging them; Once we
implement hunk editing, we will call `reassemble_patch()` whenever a
hunk is edited, therefore we must not modify the hunks (because the user
might e.g. hit `K` and change their mind whether to stage the previous
hunk).

If this developer's workflow is any indication, then this is *the* most
useful feature of Git's interactive `add `command.
Note: once again, this is not a verbatim conversion from the Perl code
to C: the `hunk_splittable()` function, for example, essentially did all
the work of splitting the hunk, just to find out whether more than one
hunk would have been the result (and then tossed that result into the
trash). In C we instead count the number of resulting hunks (without
actually doing the work of splitting, but just counting the transitions
from non-context lines to context lines), and store that information
with the hunk, and we do that *while* parsing the diff in the first
place.
Another deviation: the built-in `git add -p` was designed with a single
strbuf holding the diff (and another one holding the colored diff, if
that one was asked for) in mind, and hunks essentially store just the
start and end offsets pointing into that strbuf. As a consequence, when
we split hunks, we now use a special mode where the hunk header is
generated dynamically, and only the rest of the hunk is stored using
such start/end offsets. This way, we also avoid the frequent
formatting/re-parsing of the hunk header of the Perl version.

Just like the Perl version, we now helpfully ask the user whether they
want to stage a mode change, or a deletion.
Note that we define the prompts in an array, in preparation for a later
patch that changes those prompts to yet different versions for `git
reset -p`, `git stash -p` and `git checkout -p` (which all call the `git
add -p` machinery to do the actual work).

This imitates the way the Perl version treats mode changes: it offers
the mode change up for the user to decide, as if it was a diff hunk.
In contrast to the Perl version, we make use of the fact that the mode
line is the first hunk, and explicitly strip out that line from the diff
header if that "hunk" was not selected to be applied, and skipping that
hunk while coalescing the diff. The Perl version plays some kind of diff
line lego instead.

This addresses the same problem as 24ab81ae4d (add-interactive: handle
deletion of empty files, 2009-10-27), although in a different way: we
not only stick the "deleted file" line into its own pseudo hunk, but
also the entire remainder (if any) of the same diff.
That way, we do not have to play any funny games with regards to
coalescing the diff after the user selected what (possibly pseudo-)hunks
to stage.

When skipping a hunk that adds a different number of lines than it
removes, we need to adjust the subsequent hunk headers of non-skipped
hunks: in pathological cases, the context is not enough to determine
precisely where the patch should be applied.
This problem was identified in 23fea4c240 (t3701: add failing test for
pathological context lines, 2018-03-01) and fixed in the Perl version in
fecc6f3a68 (add -p: adjust offsets of subsequent hunks when one is
skipped, 2018-03-01).
And this patch fixes it in the C version of `git add -p`.
In contrast to the Perl version, we try to keep the extra text on the
hunk header (which typically contains the signature of the function
whose code is changed in the hunk) intact.
Note: while the C version does not support staging mode changes at this
stage, we already prepare for this by simply skipping the hunk header if
both old and new offset is 0 (this cannot happen for regular hunks, and
we will use this as an indicator that we are looking at a special hunk).
Likewise, we already prepare for hunk splitting by handling the absence
of extra text in the hunk header gracefully: only the first split hunk
will have that text, the others will not (indicated by an empty extra
text start/end range). Preparing for hunk splitting already at this
stage avoids an indentation change of the entire hunk header-printing
block later, and is almost as easy to review as without that handling.

Just like the Perl version, we now generate two diffs if `color.diff` is
set: one with and one without color. Then we parse them in parallel and
record which hunks start at which offsets in both.
Note that this is a (slight) deviation from the way the Perl version did
it: we are no longer reading the output of `diff-files` line by line
(which is more natural for Perl than for C), but in one go, and parse
everything later, so we might just as well do it in synchrony.

The code in `git-add--interactive.perl` that takes care of the `patch`
command can look quite intimidating. There are so many modes in which it
can be called, for example.
But for the `patch` command in `git add -i`, only one mode is relevant:
the `stage` mode. And we just implemented the beginnings of that mode in
C so far. So let's use it when `add.interactive.useBuiltin=true`.
Now, while the code in `add-patch.c` is far from reaching feature parity
with the code in `git-add--interactive.perl` (color is not implemented,
the diff algorithm cannot be configured, the colored diff cannot be
post-processed via `interactive.diffFilter`, many commands are
unimplemented yet, etc), hooking it all up with the part of `git add -i`
that is already converted to C makes it easier to test and develop it.
Note: at this stage, both the `add.interactive.useBuiltin` config
setting is still safely opt-in, and will probably be fore quite some
time, to allow for thorough testing "in the wild" without adversely
affecting existing users.

In the previous steps, we re-implemented the main loop of `git add -i`
in C, and most of the commands.
Notably, we left out the actual functionality of `patch`, as the
relevant code makes up more than half of `git-add--interactive.perl`,
and is actually pretty independent of the rest of the commands.
With this commit, we start to tackle that `patch` part. For better
separation of concerns, we keep the code in a separate file,
`add-patch.c`. The new code is still guarded behind the
`add.interactive.useBuiltin` config setting, and for the moment,
it can only be called via `git add -p`.
The actual functionality follows the original implementation of
5cde71d64aff (git-add --interactive, 2006-12-10), but not too closely
(for example, we use string offsets rather than copying strings around,
and after seeing whether the `k` and `j` commands are applicable, in the
C version we remember which previous/next hunk was undecided, and use it
rather than looking again when the user asked to jump).
As a further deviation from that commit, We also use a comma instead of
a slash to separate the available commands in the prompt, as the current
version of the Perl script does this, and we also add a line about the
question mark ("print help") to the help text.
While it is tempting to use this conversion of `git add -p` as an excuse
to work on `apply_all_patches()` so that it does _not_ want to read a
file from `stdin` or from a file, but accepts, say, an `strbuf` instead,
we will refrain from this particular rabbit hole at this stage.

Yes, yes, this is supposed to be only a band-aid option for `git add -p`
not Doing The Right Thing. But as long as we carry the `--allow-overlap`
option, we might just as well get it right.
This fixes the case where one hunk inserts a line before the first line,
and is followed by a hunk whose context overlaps with the first one's
and which appends a line at the end.

The first thing `git add -p` does is to generate a diff. If this diff
cannot be generated, `git add -p` should not continue as if nothing
happened, but instead fail.
What we *actually* do here is much broader: we now verify for *every*
`run_cmd_pipe()` call that the spawned process actually succeeded.
Note that we have to change two callers in this patch, as we need to
store the spawned process' output in a local variable, which means that
the callers can no longer decide whether to interpret the `return <$fh>`
in array or in scalar context.
This bug was noticed while writing a test case for the diff.algorithm
feature, and we let that test case double as a regression test for this
fixed bug, too.

In preparation for re-implementing `git add -p` in pure C (where we will

The `git add -p` command offers different prompts for regular diff hunks
vs mode change pseudo hunks vs diffs deleting files.
Let's cover this in the regresion test suite, in preparation for
re-implementing `git add -p` in C.
For the mode change prompt, we use a trick that lets this test case pass
even on systems without executable bit, i.e. where `core.filemode =
false` (such as Windows): we first add the file to the index with `git
add --chmod=+x`, and then call `git add -p` with `core.filemode` forced
to `true`. The file on disk has no executable bit set, therefore we will
see a mode change.

The TTY prerequisite is a rather heavy one: it not only requires Perl to
work, but also the IO/Pty.pm module (with native support, and it
requires pseudo terminals, too).
In particular, test cases marked with the TTY prerequisite would be
skipped in Git for Windows' SDK.
In the case of `git add -p`, we do not actually need that big a hammer,
as we do not want to test any functionality that requires a pseudo
terminal; all we want is for the interactive add command to use color,
even when being called from within the test suite.
And we found exactly such a trick earlier already: when we added a test
case to verify that the main loop of `git add -i` is colored
appropriately. Let's use that trick instead of the TTY prerequisite.
While at it, we avoid the pipes, as we do not want a SIGPIPE to break
the regression test cases (which will be much more likely when we do not
run everything through Perl because that is inherently slower).

In this developer's workflows, it often happens that a hunk needs to be
edited in a way that adds lines, and sometimes even reduces the number
of context lines.
Let's add a regression test for this.
Note that just like the preceding test case, the new test case is *not*
handled gracefully by the current `git add -p`. It will be handled
correctly by the upcoming built-in `git add -p`, though.

After `status` and `help`, it is now time to port the `update` command
to C, the second command that is shown in the main loop menu of `git add
-i`.
This `git add -i` command is the first one which lets the user choose a
subset of a list of files, and as such, this patch lays the groundwork
for the other commands of that category:
- It teaches the `print_file_item()` function to show a unique prefix
if we found any (the code to find it had been added already in the
previous patch where we colored the unique prefixes of the main loop
commands, but that patch uses the `print_command_item()` function to
display the menu items).
- This patch also adds the help text that is shown when the user input
to select items from the shown list could not be parsed.
- As `get_modified_files()` clears the list of files, it now has to take
care of clearing the _full_ `prefix_item_list` lest the `sorted` and
`selected` fields go stale and inconsistent.

In the `update` command of `git add -i`, we are primarily interested in the
list of modified files that have worktree (i.e. unstaged) changes.
At the same time, we need to determine _also_ the staged changes, to be
able to produce the full added/deleted information.
The Perl script version of `git add -i` has a parameter of the
`list_modified()` function for that matter. In C, we can be a lot more
precise, using an `enum`.
The C implementation of the filter also has an easier time to avoid
unnecessary work, simply by using an adaptive order of the `diff-index`
and `diff-files` phases, and then skipping files in the second phase
when they have not been seen in the first phase.
Seeing as we change the meaning of the `phase` field, we rename it to
`mode` to reflect that the order depends on the exact invocation of the
`git add -i` command.

Just like in the Perl script `git-add--interactive.perl`, for each
command a unique prefix is determined (if there exists any within the
given parameters), and shown in the list, and accepted as a shortcut for
the command.
To determine the unique prefixes, as well as to look up the command in
question, we use a copy of the list and sort it.
While this might seem like overkill for a single command, it will make
much more sense when all the commands are implemented, and when we reuse
the same logic to present a list of files to edit, with convenient
unique prefixes.
At the start of the development of this patch series, a dedicated data
structure was introduced that imitated the Trie that the Perl version
implements. However, this was deemed overkill, and we now simply sort
the list before determining the length of the unique prefixes by looking
at each item's neighbor. As a bonus, we now use the same sorted list to
perform a binary search using the user-provided prefix as search key.

The reason why we did not start with the main loop to begin with is that
it is the first user of `list_and_choose()`, which uses the `list()`
function that we conveniently introduced for use by the `status`
command.
In contrast to the Perl version, in the built-in interactive `add`, we
will keep the `list()` function (which only displays items) and the
`list_and_choose()` function (which uses `list()` to display the items,
and only takes care of the "and choose" part) separate.
The `list_and_choose()` function, as implemented in
`git-add--interactive.perl` knows a few more tricks than the function we
introduce in this patch:
- There is a flag to let the user select multiple items.
- In multi-select mode, the list of items is prefixed with a marker
indicating what items have been selected.
- Initially, for each item a unique prefix is determined (if there
exists any within the given parameters), and shown in the list, and
accepted as a shortcut for the selection.
These features will be implemented in the C version later.
This patch does not add any new main loop command, of course, the
built-in `git add -i` still only supports the `status` command. The
remaining commands to follow over the course of the next commits.
To accommodate for listing the commands in columns, preparing for the
commands that will be implemented over the course of the next
patches/patch series, we teach the `list()` function to do precisely
that.
Note that we only have a prompt ending in a single ">" at this stage;
later commits will add commands that display a double ">>" to indicate
that the user is in a different loop than the main one.

At this point, we re-implement only part of the `list_and_choose()`

This is helpful for code that may want to easily extract information

Unlike previous conversions to C, where we started with a built-in
helper, we start this conversion by adding an interception in the
`run_add_interactive()` function when the new opt-in
`add.interactive.useBuiltin` config knob is turned on (or the
corresponding environment variable `GIT_TEST_ADD_I_USE_BUILTIN`), and
calling the new internal API function `run_add_i()` that is implemented
directly in libgit.a.
At this point, the built-in version of `git add -i` only states that it
cannot do anything yet. In subsequent patches/patch series, the
`run_add_i()` function will gain more and more functionality, until it
is feature complete. The whole arc of the conversion can be found in the
PRs #170-175 at https://github.com/gitgitgadget/git.
The "--helper approach" can unfortunately not be used here: on Windows
we face the very specific problem that a `system()` call in
Perl seems to close `stdin` in the parent process when the spawned
process consumes even one character from `stdin`. Which prevents us from
implementing the main loop in C and still trying to hand off to the Perl
script.
The very real downside of the approach we have to take here is that the
test suite won't pass with `GIT_TEST_ADD_I_USE_BUILTIN=true` until the
conversion is complete (the `--helper` approach would have let it pass,
even at each of the incremental conversion steps).

As per Wikipedia, "In current technical usage, for one to state that a
feature is deprecated is merely a recommendation against using it." It
is thus contradictory to claim that something is not "officially
deprecated" and then to immediately state that we are both discouraging
its use and pointing people elsewhere.

We recently regressed our rendering with Asciidoctor of "literal"
elements in our manpages, i.e, stuff we have placed within `backticks`
in order to render as monospace. In particular, we lost the bold
rendering of such literal text.
The culprit is f6461b82b9 ("Documentation: fix build with Asciidoctor 2",
2019-09-15), where we switched from DocBook 4.5 to DocBook 5 with
Asciidoctor. As part of the switch, we started using the namespaced
DocBook XSLT stylesheets rather than the non-namespaced ones. (See
f6461b82b9 for more details on why we changed to the namespaced ones.)
The bold literals are implemented as an XSLT snippet <xsl:template
match="literal">...</xsl:template>. Now that we use namespaces, this
doesn't pick up our literals like it used to.
Match for "d:literal" in addition to just "literal", after defining the
d namespace. ("d" is what
http://docbook.sourceforge.net/release/xsl-ns/current/manpages/docbook.xsl
uses.) Note that we need to keep matching without the namespace for
AsciiDoc.
This boldness was introduced by 5121a6d993 ("Documentation: option to
render literal text as bold for manpages", 2009-03-27) and made the
default in 5945717009 ("Documentation: bold literals in man",
2016-05-31).
One reason this was not caught in review is that our doc-diff tool diffs
without any boldness, i.e., it "only" compares text. As pointed out by
Peff in review of this patch, one can use `MAN_KEEP_FORMATTING=1
./doc-diff <...>`
This has been optically tested with AsciiDoc 8.6.10, Asciidoctor 1.5.5
and Asciidoctor 2.0.10. I've also verified that doc-diff produces the
empty output for all three programs, as expected, and that with the
MAN_KEEP_FORMATTING trick, AsciiDoc yields no diff, whereas with
Asciidoctor, we get bold literals, just like we want.
