After performing a merge that has conflicts git status will, by default,
attempt to detect renames which causes many objects to be examined. In a
virtualized repo, those objects do not exist locally so the rename logic
triggers them to be fetched from the server. This results in the status call
taking hours to complete on very large repos vs seconds with this patch.
Add a new config status.renames setting to enable turning off rename
detection during status and commit. This setting will default to the value
of diff.renames.
Add a new config status.renamelimit setting to to enable bounding the time
spent finding out inexact renames during status and commit. This setting
will default to the value of diff.renamelimit.
Add --no-renames command line option to status that enables overriding the
config setting from the command line. Add --find-renames[=<n>] command line
option to status that enables detecting renames and optionally setting the
similarity index.

t2203: test status output with porcelain v2 format
It is possible to have the output ' A' from 'git status --porcelain'
by adding a file using the '--intend-to-add' flag. Make this clear by
adding the pattern in the table of the documentation.
However the mode 'DM' (deleted in the index, modified in the working tree)
is not possible in the non-merge case in which the file only shows
as 'D ' (and adding it back to the worktree would show an additional line
of an '??' untracked file). It is also not possible in the merge case as
then the mode involves a 'U' on one side of the merge.
Remove that pattern.

When "--no-ahead-behind" is given, the existing porcelain V2 line
"branch.ab +x -y" is replaced with a new "branch.ab +? -?" line.
This indicates that the branch and its upstream are or are not equal

t2203: test status output with porcelain v2 format
Before 425a28e0a4 (diff-lib: allow ita entries treated as "not yet exist
in index" - 2016-10-24) there are never "new files" in the index, which
essentially disables rename detection because we only detect renames
when a new file appears in a diff pair.
After that commit, an i-t-a entry can appear as a new file in "git
diff-files". But the diff callback function in wt-status.c does not
handle this case and produces incorrect status output.
PS. The reader may notice that this patch adds a new xstrdup() but not
a free(). Yes we leak memory (the same for head_path). But wt_status
so far has been short lived, this leak should not matter in
practice.

If you come to the documentation thinking "I do not want Git
to take any locks for my background processes", then you may
easily run across "--no-optional-locks" in git.txt.
But it's quite reasonable to hit a specific instance of the
problem: you have "git status" running in the background,
and you notice that it causes lock contention with other
processes. So you look in git-status.txt to see if there is
a way to disable it, but there's no mention of the flag.
Let's add a short note mentioning that status does indeed
touch the index (and why), with a pointer to the global
option. That can point users in the right direction and help
them make a more informed decision about what they're

Suppose I have a superproject 'super', with two submodules 'super/sub'
and 'super/sub1'. 'super/sub' itself contains a submodule
'super/sub/subsub'. Now suppose I run, from within 'super':
echo hi >sub/subsub/stray-file
echo hi >sub1/stray-file
Currently we get would see the following output in git-status:
git status --short
m sub
? sub1
With this patch applied, the untracked file in the nested submodule is
displayed as an untracked file on the 'super' level as well.
git status --short
? sub
? sub1
This doesn't change the output of 'git status --porcelain=1' for nested
submodules, because its output is always ' M' for either untracked files
or local modifications no matter the nesting level of the submodule.
'git status --porcelain=2' is affected by this change in a nested
submodule, though. Without this patch it would report the direct submodule
as modified and having no untracked files. With this patch it would report
untracked files. Chalk this up as a bug fix.
This bug fix also affects the default output (non-short, non-porcelain)
of git-status, which is not tested here.

If I add an untracked file to a submodule or modify a tracked file,
currently "git status --short" treats the change in the same way as
changes to the current HEAD of the submodule:
$ git clone --quiet --recurse-submodules https://gerrit.googlesource.com/gerrit
$ echo hello >gerrit/plugins/replication/stray-file
$ sed -i -e 's/.*//' gerrit/plugins/replication/.mailmap
$ git -C gerrit status --short
M plugins/replication
This is by analogy with ordinary files, where "M" represents a change
that has not been added yet to the index. But this change cannot be
added to the index without entering the submodule, "git add"-ing it,
and running "git commit", so the analogy is counterproductive.
Introduce new status letters " ?" and " m" for this. These are similar
to the existing "??" and " M" but mean that the submodule (not the
parent project) has new untracked files and modified files, respectively.
The user can use "git add" and "git commit" from within the submodule to
add them.
Changes to the submodule's HEAD commit can be recorded in the index with
a plain "git add -u" and are shown with " M", like today.
To avoid excessive clutter, show at most one of " ?", " m", and " M" for
the submodule. They represent increasing levels of change --- the last
one that applies is shown (e.g., " m" if there are both modified files
and untracked files in the submodule, or " M" if the submodule's HEAD
has been modified and it has untracked files).
While making these changes, we need to make sure to not break porcelain
level 1, which shares code with "status --short". We only change
"git status --short".
Non-short "git status" and "git status --porcelain=2" already handle
these cases by showing more detail:
$ git -C gerrit status --porcelain=2
1 .M S.MU 160000 160000 160000 305c864db28eb0c77c8499bc04c87de3f849cf3c 305c864db28eb0c77c8499bc04c87de3f849cf3c plugins/replication
$ git -C gerrit status
[...]
modified: plugins/replication (modified content, untracked content)
Scripts caring about these distinctions should use --porcelain=2.

* Document the syntax of these options.
For the second point, the behavior is documented in gitcli(7), but it is
easy for users to miss, and hard for the same user to understand why e.g.
"git status -u no" does not work.
Document this explicitly in the documentation of each short option having

You can currently set the output format to --short or
--porcelain. There is no --long, because we default to it
already. However, you may want to override an alias that
uses "--short" to get back to the default.
This requires a little bit of refactoring, because currently
we use STATUS_FORMAT_LONG internally to mean the same as
"the user did not specify anything". By expanding the enum
to include STATUS_FORMAT_NONE, we can distinguish between
the implicit and explicit cases. This effects these
conditions:
1. The user has asked for NUL termination. With NONE, we
currently default to turning on the porcelain mode.
With an explicit --long, we would in theory use NUL
termination with the long mode, but it does not support
it. So we can just complain and die.
2. When an output format is given to "git commit", we
default to "--dry-run". This behavior would now kick in
when "--long" is given, too.

In asciidoc 7, backticks like `foo` produced a typographic
effect, but did not otherwise affect the syntax. In asciidoc
8, backticks introduce an "inline literal" inside which markup
is not interpreted. To keep compatibility with existing
documents, asciidoc 8 has a "no-inline-literal" attribute to
keep the old behavior. We enabled this so that the
documentation could be built on either version.
It has been several years now, and asciidoc 7 is no longer
in wide use. We can now decide whether or not we want
inline literals on their own merits, which are:
1. The source is much easier to read when the literal
contains punctuation. You can use `master~1` instead
of `master{tilde}1`.
2. They are less error-prone. Because of point (1), we
tend to make mistakes and forget the extra layer of
quoting.
This patch removes the no-inline-literal attribute from the
Makefile and converts every use of backticks in the
documentation to an inline literal (they must be cleaned up,
or the example above would literally show "{tilde}" in the
output).
Problematic sites were found by grepping for '`.*[{\\]' and
examined and fixed manually. The results were then verified
by comparing the output of "html2text" on the set of
generated html pages. Doing so revealed that in addition to
making the source more readable, this patch fixes several
formatting bugs:
- HTML rendering used the ellipsis character instead of
literal "..." in code examples (like "git log A...B")
- some code examples used the right-arrow character
instead of '->' because they failed to quote
- api-config.txt did not quote tilde, and the resulting
HTML contained a bogus snippet like:
<tt><sub></tt> foo <tt></sub>bar</tt>
which caused some parsers to choke and omit whole
sections of the page.
- git-commit.txt confused ``foo`` (backticks inside a
literal) with ``foo'' (matched double-quotes)
- mentions of `A U Thor <author@example.com>` used to
erroneously auto-generate a mailto footnote for
author@example.com
- the description of --word-diff=plain incorrectly showed
the output as "[-removed-] and {added}", not "{+added+}".
- using "prime" notation like:
commit `C` and its replacement `C'`
confused asciidoc into thinking that everything between
the first backtick and the final apostrophe were meant
to be inside matched quotes
- asciidoc got confused by the escaping of some of our
asterisks. In particular,
`credential.\*` and `credential.<url>.\*`
properly escaped the asterisk in the first case, but
literally passed through the backslash in the second
case.

The SYNOPSIS sections of most commands that span several lines already
use [verse] to retain line breaks. Most commands that don't span
several lines seem not to use [verse]. In the HTML output, [verse]
does not only preserve line breaks, but also makes the section
indented, which causes a slight inconsistency between commands that
use [verse] and those that don't. Use [verse] in all SYNOPSIS sections
for consistency.
Also remove the blank lines from git-fetch.txt and git-rebase.txt to
align with the other man pages. In the case of git-rebase.txt, which
already uses [verse], the blank line makes the [verse] not apply to
the last line, so removing the blank line also makes the formatting
within the document more consistent.
While at it, add single quotes to 'git cvsimport' for consistency with

Recent versions of asciidoc will treat "->" as a
single-glyph arrow symbol, unless it is inside a literal
code block. This is a problem if we are discussing literal
output and want to show the ASCII characters.
Our usage falls into three categories:
1. Inside a code block. These can be left as-is.
2. Discussing literal output or code, but inside a
paragraph. This patch escapes these as "\->".
3. Using the arrow as a symbolic element, such as "use the
Edit->Account Settings menu". In this case, the
arrow symbol is preferable, so we leave it as-is.

The point of these sections is generally to:
1. Give credit where it is due.
2. Give the reader an idea of where to ask questions or
file bug reports.
But they don't do a good job of either case. For (1), they
are out of date and incomplete. A much more accurate answer
can be gotten through shortlog or blame. For (2), the
correct contact point is generally git@vger, and even if you
wanted to cc the contact point, the out-of-date and
incomplete fields mean you're likely sending to somebody
useless.
So let's drop the fields entirely from all manpages except
git(1) itself. We already point people to the mailing list
for bug reports there, and we can update the Authors section
to give credit to the major contributors and point to
shortlog and blame for more information.
Each page has a "This is part of git" footer, so people can
follow that to the main git manpage.
