f37c226454 built-in add -i: prepare for multi-selection commands
The `update`, `revert` and `add-untracked` commands allow selecting
multiple entries. Let's extend the `list_and_choose()` function to
accommodate those use cases.

c08171d156 built-in add -i: allow filtering the modified files list
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.

8c15904462 built-in add -i: implement the help command
This imitates the code to show the help text from the Perl script
`git-add--interactive.perl` in the built-in version.

To make sure that it renders exactly like the Perl version of `git add
-i`, we also add a test case for that to `t3701-add-interactive.sh`.

76b743234c built-in add -i: show unique prefixes of the commands
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.

6348bfba58 built-in add -i: implement the main loop
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.

5e82b9e4d2 built-in add -i: implement the status command
This implements the `status` command of `git add -i`. The data
structures introduced in this commit will be extended later, as needed.

At this point, we re-implement only part of the `list_and_choose()`
function of the Perl script `git-add--interactive.perl` and call it
`list()`. It does not yet color anything, or do columns, or allow user
input.

Over the course of the next commits, we will introduce a
`list_and_choose()` function that uses `list()` to display the list of
options and let the user choose one or more of the displayed items. This
will be used to implement the main loop of the built-in `git add -i`, at
which point the new `status` command can actually be used.

e4cb659ebd diff: export diffstat interface
Make the diffstat interface (namely, the diffstat_t struct and
compute_diffstat) no longer be internal to diff.c and allow it to be used
by other parts of git.

This is helpful for code that may want to easily extract information
from files using the diff machinery, while flushing it differently from
how the show_* functions used by diff_flush() do it. One example is the
builtin implementation of git-add--interactive's status.

f83dff60a7 Start to implement a built-in version of git add --interactive
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).

efd5444238 RelNotes/2.24.0: fix self-contradictory note
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

55aca515eb manpage-bold-literal.xsl: match for namespaced "d:literal" in template
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.

60e6569a12 mingw: avoid a buffer overrun in needs_hiding()
When this function is passed a path with a trailing slash, it runs right
over the end of that path.

Let's fix this.

52bd3e4657 gitweb: correctly store previous rev in javascript-actions mode
Without this change, the setting

 $feature{'javascript-actions'}{'default'} = [1];

in gitweb.conf breaks gitweb's blame page: clicking on line numbers
displayed in the second column on the page has no effect.

For comparison, with javascript-actions disabled, clicking on line
numbers loads the previous version of the line.

cb99a34e23 commit-graph: fix writing first commit-graph during fetch
The previous commit includes a failing test for an issue around
fetch.writeCommitGraph and fetching in a repo with a submodule. Here, we
fix that bug and set the test to "test_expect_success".

The problem arises with this set of commands when the remote repo at
<url> has a submodule. Note that --recurse-submodules is not needed to
demonstrate the bug.

	$ git clone <url> test
	$ cd test
	$ git -c fetch.writeCommitGraph=true fetch origin
	Computing commit graph generation numbers: 100% (12/12), done.
	BUG: commit-graph.c:886: missing parent <hash1> for commit <hash2>
	Aborted (core dumped)

As an initial fix, I converted the code in builtin/fetch.c that calls
write_commit_graph_reachable() to instead launch a "git commit-graph
write --reachable --split" process. That code worked, but is not how we
want the feature to work long-term.

That test did demonstrate that the issue must be something to do with
internal state of the 'git fetch' process.

The write_commit_graph() method in commit-graph.c ensures the commits we
plan to write are "closed under reachability" using close_reachable().
This method walks from the input commits, and uses the UNINTERESTING
flag to mark which commits have already been visited. This allows the
walk to take O(N) time, where N is the number of commits, instead of
O(P) time, where P is the number of paths. (The number of paths can be
exponential in the number of commits.)

However, the UNINTERESTING flag is used in lots of places in the
codebase. This flag usually means some barrier to stop a commit walk,
such as in revision-walking to compare histories. It is not often
cleared after the walk completes because the starting points of those
walks do not have the UNINTERESTING flag, and clear_commit_marks() would
stop immediately.

This is happening during a 'git fetch' call with a remote. The fetch
negotiation is comparing the remote refs with the local refs and marking
some commits as UNINTERESTING.

I tested running clear_commit_marks_many() to clear the UNINTERESTING
flag inside close_reachable(), but the tips did not have the flag, so
that did nothing.

It turns out that the calculate_changed_submodule_paths() method is at
fault. Thanks, Peff, for pointing out this detail! More specifically,
for each submodule, the collect_changed_submodules() runs a revision
walk to essentially do file-history on the list of submodules. That
revision walk marks commits UNININTERESTING if they are simplified away
by not changing the submodule.

Instead, I finally arrived on the conclusion that I should use a flag
that is not used in any other part of the code. In commit-reach.c, a
number of flags were defined for commit walk algorithms. The REACHABLE
flag seemed like it made the most sense, and it seems it was not
actually used in the file. The REACHABLE flag was used in early versions
of commit-reach.c, but was removed by 4fbcca4 (commit-reach: make
can_all_from_reach... linear, 2018-07-20).

Add the REACHABLE flag to commit-graph.c and use it instead of
UNINTERESTING in close_reachable(). This fixes the bug in manual
testing.

e88aab917e t5510-fetch.sh: demonstrate fetch.writeCommitGraph bug
While dogfooding, Johannes found a bug in the fetch.writeCommitGraph
config behavior. His example initially happened during a clone with
--recurse-submodules, we found that this happens with the first fetch
after cloning a repository that contains a submodule:

	$ git clone <url> test
	$ cd test
	$ git -c fetch.writeCommitGraph=true fetch origin
	Computing commit graph generation numbers: 100% (12/12), done.
	BUG: commit-graph.c:886: missing parent <hash1> for commit <hash2>
	Aborted (core dumped)

In the repo I had cloned, there were really 60 commits to scan, but
only 12 were in the list to write when calling
compute_generation_numbers(). A commit in the list expects to see a
parent, but that parent is not in the list.

A follow-up will fix the bug, but first we create a test that
demonstrates the problem. This test must be careful about an existing
commit-graph file, since GIT_TEST_COMMIT_GRAPH=1 will cause the repo we
are cloning to already have one. This then prevents the incremtnal
commit-graph write during the first 'git fetch'.

c7aadccba0 fetch: delay fetch_if_missing=0 until after config
Suppose, from a repository that has ".gitmodules", we clone with
--filter=blob:none:

  git clone --filter=blob:none --no-checkout \
    https://kernel.googlesource.com/pub/scm/git/git

Then we fetch:

  git -C git fetch

This will cause a "unable to load config blob object", because the
fetch_config_from_gitmodules() invocation in cmd_fetch() will attempt to
load ".gitmodules" (which Git knows to exist because the client has the
tree of HEAD) while fetch_if_missing is set to 0.

fetch_if_missing is set to 0 too early - ".gitmodules" here should be
lazily fetched.  Git must set fetch_if_missing to 0 before the fetch
because as part of the fetch, packfile negotiation happens (and we do
not want to fetch any missing objects when checking existence of
objects), but we do not need to set it so early. Move the setting of
fetch_if_missing to the earliest possible point in cmd_fetch(), right
before any fetching happens.
