The --[no-]ahead-behind option was introduced in fd9b544a
(status: add --[no-]ahead-behind to status and commit for V2
format, 2018-01-09). This is a necessary change of behavior
in repos where the remote tracking branches can move very
quickly ahead of the local branches. However, users need to
remember to provide the command-line argument every time.
Add a new "status.aheadBehind" config setting to change the
default behavior of all git status formats.

The write_commit_graph() and write_commit_graph_reachable() methods

The write_commit_graph() method uses die() to report failure and
exit when confronted with an unexpected condition. This use of
die() in a library function is incorrect and is now replaced by
error() statements and an int return type. Return zero on success
and a negative value on failure.
Now that we use 'goto cleanup' to jump to the terminal condition
on an error, we have new paths that could lead to uninitialized
values. New initializers are added to correct for this.
The builtins 'commit-graph', 'gc', and 'commit' call these methods,
so update them to check the return value. Test that 'git commit-graph
write' returns a proper error code when hitting a failure condition
in write_commit_graph().

"git chery-pick" (and "revert" that shares the same runtime engine)
that deals with multiple commits got confused when the final step

files used by these commands in such a situation.

The list of conflicted paths shown in the editor while concluding a

The new command "git restore" (together with "git switch") are added
to avoid the confusion of one-command-do-all "git checkout" for new

For these reasons, promote it everywhere possible. This includes
documentation, suggestions/advice from other commands.
One nice thing about git-restore is the ability to restore
"everything", so it can be used in "git status" advice instead of both
"git checkout" and "git reset". The three commands suggested by "git
status" are add, rm and restore.
"git checkout" is also removed from "git help" (i.e. it's no longer
considered a commonly used command)

When cherry-picking or reverting a sequence of commits and if the final
pick/revert has conflicts and the user uses `git commit` to commit the
conflict resolution and does not run `git cherry-pick --continue` then
the sequencer state is left behind. This can cause problems later. In my
case I cherry-picked a sequence of commits the last one of which I
committed with `git commit` after resolving some conflicts, then a while
later, on a different branch I aborted a revert which rewound my HEAD to
the end of the cherry-pick sequence on the previous branch. Avoid this
potential problem by removing the sequencer state if we're committing or
resetting the final pick in a sequence.

The author.email, author.name, committer.email and committer.name
settings are analogous to the GIT_AUTHOR_* and GIT_COMMITTER_*
environment variables, but for the git config system. This allows them
to be set separately for each repository.
Git supports setting different authorship and committer
information with environment variables. However, environment variables
are set in the shell, so if different authorship and committer
information is needed for different repositories an external tool is
required.
This adds support to git config for author.email, author.name,
committer.email and committer.name settings so this information
can be set per repository.
Also, it generalizes the fmt_ident function so it can handle author vs
committer identification.

We save the result of $GIT_INDEX_FILE so that we can restore it after
setting it to a new value and running add--interactive. However, the
pointer returned by getenv() is not guaranteed to be valid after calling
setenv(). This _usually_ works fine, but can fail if libc needs to
reallocate the environment block during the setenv().
Let's just duplicate the string, so we know that it remains valid.
In the long run it may be more robust to teach interactive_add() to take
a set of environment variables to pass along to run-command when it
execs add--interactive. And then we would not have to do this
save/restore dance at all. But this is an easy fix in the meantime.

When we define a parse-options callback, the flags we put in the option
struct must match what the callback expects. For example, a callback
which does not handle the "unset" parameter should only be used with
PARSE_OPT_NONEG. But since the callback and the option struct are not
defined next to each other, it's easy to get this wrong (as earlier
patches in this series show).
Fortunately, the compiler can help us here: compiling with
-Wunused-parameters can show us which callbacks ignore their "unset"
parameters (and likewise, ones that ignore "arg" expect to be triggered
with PARSE_OPT_NOARG).
But after we've inspected a callback and determined that all of its
callers use the right flags, what do we do next? We'd like to silence
the compiler warning, but do so in a way that will catch any wrong calls
in the future.
We can do that by actually checking those variables and asserting that
they match our expectations. Because this is such a common pattern,
we'll introduce some helper macros. The resulting messages aren't
as descriptive as we could make them, but the file/line information from
BUG() is enough to identify the problem (and anyway, the point is that
these should never be seen).
Each of the annotated callbacks in this patch triggers
-Wunused-parameters, and was manually inspected to make sure all callers
use the correct options (so none of these BUGs should be triggerable).

If you run "git status --no-find-renames", it will behave the same as

"arg", but since the score argument is optional, we just think that the
user did not provide a score).
We already have a separate "--no-renames" to disable renames, so there's
not much point in supporting "--no-find-renames". Let's just flag it as

Status variables were initialized in the collect phase and some
variables were later freed in the print functions.
A "struct wt_status" used to be sufficient for the output phase to
work. It was designed to be filled in the collect phase and consumed
in the output phase, but over time some fields were added and output
phase started filling the fields.
A "struct wt_status_state" that was used in other codepaths turned out
to be useful in the "git status" output. This is not tied to "struct
wt_status", so filling in the collect phase was not consistently
followed.
Move the status state structure variables into the status state
structure and populate them in the collect functions.
Create a new function to free the buffers that were being freed in the
print function. Call this new function in commit.c where both the
collect and print functions were being called.

builtin/commit.c:prepare_to_commit() can call run_status() twice if
using the editor, including status, and the user attempts to record a
non-merge empty commit without explicit --allow-empty. If there is also
a rename involved as well (due to using 'git add -N'), then a BUG in
wt-status.c is triggered:
BUG: wt-status.c:476: multiple renames on the same target? how?
The reason we hit this bug is that both run_status() calls use the same
struct wt_status * (named s), and s->change is not freed between runs.
Changes are inserted into s with string_list_insert, which usually means
that the second run just recomputes all the same results and overwrites
what was computed the first time. However, ever since commit
176ea74793 ("wt-status.c: handle worktree renames", 2017-12-27),
wt-status started checking for renames and copies but also added a
preventative check that d->rename_status wasn't already set and output a
BUG message if it was. The problem isn't that there are multiple rename
targets to a single path as the error implies, the problem is that 's'
is not freed/cleared between the two run_status() calls.
Ever since commit dc6b1d92ca ("wt-status: use settings from
git_diff_ui_config", 2018-05-04), which stopped hardcoding
DIFF_DETECT_RENAME and allowed users to ask for copy detection, this bug
has also been triggerable with a copy instead of a rename.
Fix the bug by clearing s->change. A better change might be to clean up
all of s between the two run_status() calls. A good first step towards
such a goal might be writing a function to free the necessary fields in
the wt_status * struct; a cursory glance at the code suggests all of its
allocated data is probably leaked. However, doing all that cleanup is a
bigger task for someone else interested to tackle; just fix the bug for
now.

Refreshing the index is usually very fast, but it can still take a
long time sometimes. Cold cache is one. Or copying a repo to a new
place (*). It's good to show something to let the user know "git
status" is not hanging, it's just busy doing something.
(*) In this case, all stat info in the index becomes invalid and git
falls back to rehashing all file content to see if there's any
difference between updating stat info in the index. This is quite
expensive. Even with a repo as small as git.git, it takes 3

The commit-graph feature is tested in isolation by
t5318-commit-graph.sh and t6600-test-reach.sh, but there are many
more interesting scenarios involving commit walks. Many of these
scenarios are covered by the existing test suite, but we need to
maintain coverage when the optional commit-graph structure is not
present.
To allow running the full test suite with the commit-graph present,
add a new test environment variable, GIT_TEST_COMMIT_GRAPH. Similar
to GIT_TEST_SPLIT_INDEX, this variable makes every Git command try
to load the commit-graph when parsing commits, and writes the
commit-graph file after every 'git commit' command.
There are a few tests that rely on commits not existing in
pack-files to trigger important events, so manually set
GIT_TEST_COMMIT_GRAPH to false for the necessary commands.
There is one test in t6024-recursive-merge.sh that relies on the
merge-base algorithm picking one of two ambiguous merge-bases, and
the commit-graph feature changes which merge-base is picked.

Sometimes it helps to list all available config vars so the user can
search for something they want. The config man page can also be used
but it's harder to search if you want to focus on the variable name,
for example.
This is not the best way to collect the available config since it's
not precise. Ideally we should have a centralized list of config in C
code (pretty much like 'struct option'), but that's a lot more work.
This will do for now.

Instead of hard coding the name-to-id mapping in C code, keep it in an
array and use a common function to do the parsing. This reduces code
and also allows us to list all possible color slots later.
This starts using C99 designated initializers more for convenience
(the first designated initializers have been introduced in builtin/clean.c
for some time without complaints)

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.

If you do something like
- git add .
- git status
- git commit
- git show (or git diff HEAD)
one would expect to have analogous output from git status and git show
(or similar diff-related programs). This is generally not the case, as
git status has hard coded values for diff related options.
With this commit the hard coded settings are dropped from the status
command in favour for values provided by git_diff_ui_config.
What follows are some remarks on the concrete options which were hard
coded in git status:
diffopt.detect_rename
Since the very beginning of git status in a3e870f2e2 ("Add "commit"
helper script", 2005-05-30), git status always used rename detection,
whereas with commands like show and log one had to activate it with a
command line option. After 5404c116aa ("diff: activate diff.renames by
default", 2016-02-25) the default behaves the same by coincidence, but
changing diff.renames to other values can break the consistency between
git status and other commands again. With this commit one control the
same default behaviour with diff.renames.
diffopt.rename_limit
Similarly one has the option diff.renamelimit to adjust this limit for
all commands but git status. With this commit git status will also honor
those.
diffopt.break_opt
Unlike the other two options this cannot be configured by a
configuration option yet. This commit will also change the default
behaviour to not use break rewrites. But as rename detection is most
likely on, this is dangerous to be activated anyway as one can see
here:

stat_tracking_info: return +1 when branches not equal
We have several callers like
if (active_cache_changed && write_locked_index(...))
handle_error();
rollback_lock_file(...);
where the final rollback is needed because "!active_cache_changed"
shortcuts the if-expression. There are also a few variants of this,
including some if-else constructs that make it more clear when the
explicit rollback is really needed.
Teach `write_locked_index()` to take a new flag SKIP_IF_UNCHANGED and
simplify the callers. Leave the most complicated of the callers (in
builtin/update-index.c) unchanged. Rewriting it to use this new flag
would end up duplicating logic.
We could have made the new flag behave the other way round
("FORCE_WRITE"), but that could break existing users behind their backs.
Let's take the more conservative approach. We can still migrate existing
callers to use our new flag. Later we might even be able to flip the
default, possibly without entirely ignoring the risk to in-flight or
out-of-tree topics.

Change the behavior of git-commit back to what it was back in
d4bb43ee27 ("Invoke "git gc --auto" from commit, merge, am and
rebase.", 2007-09-05) when it was git-commit.sh.
Shortly afterwards in f5bbc3225c ("Port git commit to C.", 2007-11-08)
when it was ported to C, the "git gc --auto" invocation went away.
Since that unintended regression, git gc --auto only ran for git-am,
git-merge, git-fetch, and git-receive-pack. It was possible to
write a script that would "git commit" a lot of data locally, and gc
would never run.
One such repository that was locally committing generated zone file
changes had grown to a size of ~60GB before a daily cronjob was added
to "git gc", bringing it down to less than 1GB. This will make such
cases work without intervention.
I think fixing such pathological cases where the repository will grow
forever is a worthwhile trade-off for spending a couple of
milliseconds calling "git gc --auto" (in the common cases where it
doesn't do anything).

Add support for supplying the -m option with --fixup. Doing so has
errored out ever since --fixup was introduced. Before this, the only
way to amend the fixup message while committing was to use --edit and
amend it in the editor.
The use-case for this feature is one of:
* Leaving a quick note to self when creating a --fixup commit when
it's not self-evident why the commit should be squashed without a
note into another one.
* (Ab)using the --fixup feature to "fix up" commits that have already
been pushed to a branch that doesn't allow non-fast-forwards,
i.e. just noting "this should have been part of that other commit",
and if the history ever got rewritten in the future the two should
be combined.
In such a case you might want to leave a small message,
e.g. "forgot this part, which broke XYZ".
With this, --fixup <commit> -m"More" -m"Details" will result in a
commit message like:
!fixup <subject of <commit>>
More
Details
The reason the test being added here seems to squash "More" at the end
of the subject line of the commit being fixed up is because the test
code is using "%s%b" so the body immediately follows the subject, it's
not a bug in this code, and other tests t7500-commit.sh do the same
thing.
When the --fixup option was initially added the "Option -m cannot be
combined" error was expanded from -c, -C and -F to also include
--fixup[1]
Those options could also support combining with -m, but given what
they do I can't think of a good use-case for doing that, so I have not
made the more invasive change of splitting up the logic in commit.c to
first act on those, and then on -m options.

Move print_commit_summary() from builtin/commit.c to sequencer.c so it
can be shared with other commands. The function is modified by
changing the last argument to a flag so callers can specify whether
they want to show the author date in addition to specifying if this is
an initial commit.
If the sequencer dies in print_commit_summary() (which can only happen
when cherry-picking or reverting) then neither the todo list nor the
abort safety file are updated to reflect the commit that was just
made. print_commit_summary() can die if:
- The commit that was just created cannot be found or parsed.
- HEAD cannot be resolved either because some other process is
updating it (which is bad news in the middle of a cherry-pick) or
because it is corrupt.
- log_tree_commit() cannot read some objects.
In all those cases dying will leave the sequencer in a sane state for
aborting; 'git cherry-pick --abort' will rewind HEAD to the last
successful commit before there was a problem with HEAD or the object
database. If the user somehow fixes the problem and runs 'git
cherry-pick --continue' then the sequencer will try and pick the same
commit again which may or may not be what the user wants depending on
what caused print_commit_summary() to die. If print_commit_summary()
returned an error instead then update_abort_safety_file() would try to
resolve HEAD which may or may not be successful. If it is successful
then running 'git rebase --abort' would not rewind HEAD to the last
successful commit which is not what we want.

Teach the status command more flexibility in how ignored files are
reported. Currently, the reporting of ignored files and untracked
files are linked. You cannot control how ignored files are reported
independently of how untracked files are reported (i.e. `all` vs
`normal`). This makes it impossible to show untracked files with the
`all` option, but show ignored files with the `normal` option.
This work 1) adds the ability to control the reporting of ignored
files independently of untracked files and 2) introduces the concept
of status reporting ignored paths that explicitly match an ignored
pattern. There are 2 benefits to these changes: 1) if a consumer needs
all untracked files but not all ignored files, there is a performance
benefit to not scanning all contents of an ignored directory and 2)
returning ignored files that explicitly match a path allow a consumer
to make more informed decisions about when a status result might be
stale.
This commit implements --ignored=matching with --untracked-files=all.
The following commit will implement --ignored=matching with
--untracked=files=normal.
As an example of where this flexibility could be useful is that our
application (Visual Studio) runs the status command and presents the
output. It shows all untracked files individually (e.g. using the
'--untracked-files==all' option), and would like to know about which
paths are ignored. It uses information about ignored paths to make
decisions about when the status result might have changed.
Additionally, many projects place build output into directories inside
a repository's working directory (e.g. in "bin/" and "obj/"
directories). Normal usage is to explicitly ignore these 2 directory
names in the .gitignore file (rather than or in addition to the *.obj
pattern).If an application could know that these directories are
explicitly ignored, it could infer that all contents are ignored as
well and make better informed decisions about files in these
directories. It could infer that any changes under these paths would
not affect the output of status. Additionally, there can be a
significant performance benefit by avoiding scanning through ignored
directories.
When status is set to report matching ignored files, it has the
following behavior. Ignored files and directories that explicitly
match an exclude pattern are reported. If an ignored directory matches
an exclude pattern, then the path of the directory is returned. If a
directory does not match an exclude pattern, but all of its contents
are ignored, then the contained files are reported instead of the
directory.

`write_locked_index()` takes two flags: `COMMIT_LOCK` and `CLOSE_LOCK`.
At most one is allowed. But it is also possible to use no flag, i.e.,
`0`. But when `write_locked_index()` calls `do_write_index()`, the
temporary file, a.k.a. the lockfile, will be closed. So passing `0` is
effectively the same as `CLOSE_LOCK`, which seems like a bug.
We might feel tempted to restructure the code in order to close the file
later, or conditionally. It also feels a bit unfortunate that we simply
"happen" to close the lock by way of an implementation detail of
lockfiles. But note that we need to close the temporary file before
`stat`-ing it, at least on Windows. See 9f41c7a6b (read-cache: close
index.lock in do_write_index, 2017-04-26).
Drop `CLOSE_LOCK` and make it explicit that `write_locked_index()`
always closes the lock. Whether it is also committed is governed by the
remaining flag, `COMMIT_LOCK`.
This means we neither have nor suggest that we have a mode to write the
index and leave the file open. Whatever extra contents we might
eventually want to write, we should probably write it from within
`write_locked_index()` itself anyway.
