When a patch inserts a block of lines, whose last lines are the
same as the existing lines that appear before the inserted block,
"git diff" can choose any place between these existing lines as the
boundary between the pre-context and the added lines (adjusting the
end of the inserted block as appropriate) to come up with variants
of the same patch, and some variants are easier to read than others.
We have been trying to improve the choice of this boundary, and Git
2.11 shipped with an experimental "compaction-heuristic". Since
then another attempt to improve the logic further resulted in a new
"indent-heuristic" logic. It is agreed that the latter gives better
result overall, and the former outlived its usefulness.
Retire "compaction", and keep "indent" as an experimental feature.
The latter hopefully will be turned on by default in a future
release, but that should be done as a separate step.

If a submodule was renamed at any point since it's inception then if you
were to try and grep on a commit prior to the submodule being moved, you
wouldn't be able to find a working directory for the submodule since the
path in the past is different from the current path.
This patch teaches grep to find the .git directory for a submodule in
the parents .git/modules/ directory in the event the path to the
submodule in the commit that is being searched differs from the state of
the currently checked out commit. If found, the child process that is
spawned to grep the submodule will chdir into its gitdir instead of a
working directory.
In order to override the explicit setting of submodule child process's
gitdir environment variable (which was introduced in '10f5c526')
`GIT_DIR_ENVIORMENT` needs to be pushed onto child process's env_array.
This allows the searching of history from a submodule's gitdir, rather
than from a working directory.

Teach grep to recursively search in submodules when provided with a
<tree> object. This allows grep to search a submodule based on the state
of the submodule that is present in a commit of the super project.
When grep is provided with a <tree> object, the name of the object is
prefixed to all output. In order to provide uniformity of output
between the parent and child processes the option `--parent-basename`
has been added so that the child can preface all of it's output with the
name of the parent's object instead of the name of the commit SHA1 of
the submodule. This changes output from the command
`git grep -e. -l --recurse-submodules HEAD` from:
HEAD:file
<commit sha1 of submodule>:sub/file
to:
HEAD:file
HEAD:sub/file

Allow grep to recognize submodules and recursively search for patterns in
each submodule. This is done by forking off a process to recursively
call grep on each submodule. The top level --super-prefix option is
used to pass a path to the submodule which can in turn be used to
prepend to output or in pathspec matching logic.
Recursion only occurs for submodules which have been initialized and
checked out by the parent project. If a submodule hasn't been
initialized and checked out it is simply skipped.
In order to support the existing multi-threading infrastructure in grep,
output from each child process is captured in a strbuf so that it can be
later printed to the console in an ordered fashion.
To limit the number of theads that are created, each child process has
half the number of threads as its parents (minimum of 1), otherwise we
potentailly have a fork-bomb.

You can run "git index-pack path/to/foo.pack" outside of a

we obviously do not have any objects to collide with.
The current code will blindly look in .git/objects based on
the result of setup_git_env(). That effectively gives us the
right answer (since we won't find any objects), but it's a
waste of time, and it conflicts with our desire to
eventually get rid of the "fallback to .git" behavior of
setup_git_env().

Add functionality to migrate the git directory to be absorbed

The newly added code in this patch is structured such that other areas of
Git can also make use of it. The code in the submodule--helper is a mere
wrapper and option parser for the function
`absorb_git_dir_into_superproject`, that takes care of embedding the
submodules git directory into the superprojects git dir. That function
makes use of the more abstract function for this use case
`relocate_gitdir`, which can be used by e.g. the worktree code eventually

search for possible alternates for nested submodules as well.

Callers of the hold_locked_index() function pass 0 when they want to
prepare to write a new version of the index file without wishing to
die or emit an error message when the request fails (e.g. somebody
else already held the lock), and pass 1 when they want the call to
die upon failure.
This option is called LOCK_DIE_ON_ERROR by the underlying lockfile
API, and the hold_locked_index() function translates the paramter to
LOCK_DIE_ON_ERROR when calling the hold_lock_file_for_update().
Replace these hardcoded '1' with LOCK_DIE_ON_ERROR and stop
translating. Callers other than the ones that are replaced with
this change pass '0' to the function; no behaviour change is
intended with this patch.

---
Among the callers of hold_locked_index() that passes 0:
- diff.c::refresh_index_quietly() at the end of "git diff" is an
opportunistic update; it leaks the lockfile structure but it is
just before the program exits and nobody should care.
- builtin/describe.c::cmd_describe(),
builtin/commit.c::cmd_status(),
sequencer.c::read_and_refresh_cache() are all opportunistic
updates and they are OK.
- builtin/update-index.c::cmd_update_index() takes a lock upfront
but we may end up not needing to update the index (i.e. the
entries may be fully up-to-date), in which case we do not need to
issue an error upon failure to acquire the lock. We do diagnose
and die if we indeed need to update, so it is OK.
- wt-status.c::require_clean_work_tree() IS BUGGY. It asks
silence, does not check the returned value. Compare with
callsites like cmd_describe() and cmd_status() to notice that it
is wrong to call update_index_if_able() unconditionally.
This options makes sorting ignore case, which is great when you have
branches named bug-12-do-something, Bug-12-do-some-more and
BUG-12-do-what and want to group them together. Sorting externally may
not be an option because we lose coloring and column layout from
git-branch and git-tag.
The same could be said for filtering, but it's probably less important
because you can always go with the ugly pattern [bB][uU][gG]-* if you're
desperate.
You can't have case-sensitive filtering and case-insensitive sorting (or
the other way around) with this though. For branch and tag, that should
be no problem. for-each-ref, as a plumbing, might want finer control.
But we can always add --{filter,sort}-ignore-case when there is a need
for it.

This is required by git-worktree.txt, stating that the main worktree is
the first line (especially in --porcelain mode when we can't just change
behavior at will).
There's only one case when get_worktrees() may skip main worktree, when
parse_ref() fails. Update the code so that we keep first item as main
worktree and return something sensible in this case:
- In user-friendly mode, since we're not constraint by anything,
returning "(error)" should do the job (we already show "(detached
HEAD)" which is not machine-friendly). Actually errors should be
printed on stderr by parse_ref() (*)
- In plumbing mode, we do not show neither 'bare', 'detached' or
'branch ...', which is possible by the format description if I read
it right.
Careful readers may realize that when the local variable "head_ref" in
get_main_worktree() is emptied, add_head_info() will do nothing to
wt->head_sha1. But that's ok because head_sha1 is zero-ized in the
previous patch.
(*) Well, it does not. But it's supposed to be a stop gap implementation
until we can reuse refs code to parse "ref: " stuff in HEAD, from
resolve_refs_unsafe(). Now may be the time since refs refactoring is
mostly done.
