Recent addition of "directory rename" heuristics to the
merge-recursive backend makes the command susceptible to false
positives and false negatives. In the context of "git am -3",
which does not know about surrounding unmodified paths and thus
cannot inform the merge machinery about the full trees involved,
this risk is particularly severe. As such, the heuristic is
disabled for "git am -3" to keep the machinery "more stupid but
predictable".

Make the convert API take an index_state instead of assuming the_index
in convert.c. All external call sites are converted blindly to keep
the patch simple and retain current behavior. Individual call sites
may receive further updates to use the right index instead of
the_index.

When the sparse checkout feature is in use, "git cherry-pick" and
other mergy operations lost the skip_worktree bit when a path that
is excluded from checkout requires content level merge, which is
resolved as the same as the HEAD version, without materializing the
merge result in the working tree, which made the path appear as
deleted. This has been corrected by preserving the skip_worktree
bit (and not materializing the file in the working tree).

merge-recursive takes any files marked as unmerged by unpack_trees,
tries to figure out whether they can be resolved (e.g. using renames
or a file-level merge), and then if they can be it will delete the old
cache entries and writes new ones. This means that any ce_flags for
those cache entries are essentially cleared when merging.
Unfortunately, if a file was marked as skip_worktree and it needs a
file-level merge but the merge results in the same version of the file
that was found in HEAD, we skip updating the worktree (because the
file was unchanged) but clear the skip_worktree bit (because of the
delete-cache-entry-and-write-new-one). This makes git treat the file
as having a local change in the working copy, namely a delete, when it
should appear as unchanged despite not being present. Avoid this
problem by copying the skip_worktree flag in this case.

builtin/merge.c says that when we are about to perform a merge:
...the index must be in sync with the head commit. The strategies are
responsible to ensure this.
merge-recursive has always relied on unpack_trees() to enforce this
requirement, except in the case of an "Already up to date!" merge.
unpack-trees.c does not actually enforce this requirement, though. It
allows for a pair of exceptions, in cases which it refers to as #14(ALT)
and #2ALT. Documentation/technical/trivial-merge.txt can be consulted for
the precise meanings of the various case numbers and their meanings for
unpack-trees.c, but we have a high-level description of the intent behind
these two exceptions in a combined and summarized form in
Documentation/git-merge.txt:
...[merge will] abort if there are any changes registered in the index
relative to the `HEAD` commit. (One exception is when the changed index
entries are in the state that would result from the merge already.)
While this high-level description does describe conditions under which it
would be safe to allow the index to diverge from HEAD, it does not match
what is actually implemented. In particular, unpack-trees.c has no
knowledge of renames, and these two exceptions were written assuming that
no renames take place. Once renames get into the mix, it is no longer
safe to allow the index to not match for #2ALT. We could modify
unpack-trees to only allow #14(ALT) as an exception, but that would be
more strict than required for the resolve strategy (since the resolve
strategy doesn't handle renames at all). Therefore, unpack_trees.c seems
like the wrong place to fix this.
Further, if someone fixes the combination of break and rename detection
and modifies merge-recursive to take advantage of the combination, then it
will also no longer be safe to allow the index to not match for #14(ALT)
when the recursive strategy is in use. Therefore, leaving one of the
exceptions in place with the recursive merge strategy feels like we are
just leaving a latent bug in the code for folks in the future to stumble
across.
It may be possible to fix both unpack-trees and merge-recursive in a way
that implements the exception as stated in Documentation/git-merge.txt,
but it would be somewhat complex, possibly also buggy at first, and
ultimately, not all that valuable. Instead, just enforce the requirement
stated in builtin/merge.c; error out if the index does not match the HEAD
commit, just like the 'ours' and 'octopus' strategies do.
Some testcase fixups were in order:
t7611: had many tests designed to show that `git merge --abort` could
not always restore the index and working tree to the state they
were in before the merge started. The tests that were associated
with having changes in the index before the merge started are no
longer applicable, so they have been removed.
t7504: had a few tests that had stray staged changes that were not
actually part of the test under consideration
t6044: We no longer expect stray staged changes to sometimes result
in the merge continuing. Also, fix a case where a merge
didn't abort but should have.

`git merge-recursive` does a three-way merge between user-specified trees
base, head, and remote. Since the user is allowed to specify head, we can
not necesarily assume that head == HEAD.
Modify index_has_changes() to take an extra argument specifying the tree
to compare against. If NULL, it will compare to HEAD. We then use this
from merge-recursive to make sure we compare to the user-specified head.

In commit 65170c07d4 ("merge-recursive: avoid incorporating uncommitted
changes in a merge", 2017-12-21), it was noted that there was a special
case when merge-recursive didn't rely on unpack_trees() to enforce the
index == HEAD requirement, and thus that it needed to do that enforcement
itself. Unfortunately, it returned the wrong exit status, signalling that
the merge completed but had conflicts, rather than that it was aborted.
Fix the return code, and while we're at it, change the error message to
match what unpack_trees() would have printed.

Modify index_has_changes() to take a struct istate* instead of just
operating on the_index. This is only a partial conversion, though,
because we call do_diff_cache() which implicitly assumes work is to be
done on the_index. Ongoing work is being done elsewhere to do the
remainder of the conversion, and thus is not duplicated here. Instead,
a simple check is put in place until that work is complete.

It has been observed that the time spent loading an index with a large
number of entries is partly dominated by malloc() calls. This change
is in preparation for using memory pools to reduce the number of
malloc() calls made to allocate cahce entries when loading an index.
Add an API to allocate and discard cache entries, abstracting the
details of managing the memory backing the cache entries. This commit
does actually change how memory is managed - this will be done in a
later commit in the series.
This change makes the distinction between cache entries that are
associated with an index and cache entries that are not associated with
an index. A main use of cache entries is with an index, and we can
optimize the memory management around this. We still have other cases
where a cache entry is not persisted with an index, and so we need to
handle the "transient" use case as well.
To keep the congnitive overhead of managing the cache entries, there
will only be a single discard function. This means there must be enough
information kept with the cache entry so that we know how to discard
them.
A summary of the main functions in the API is:
make_cache_entry: create cache entry for use in an index. Uses specified
parameters to populate cache_entry fields.
make_empty_cache_entry: Create an empty cache entry for use in an index.
Returns cache entry with empty fields.
make_transient_cache_entry: create cache entry that is not used in an
index. Uses specified parameters to populate
cache_entry fields.
make_empty_transient_cache_entry: create cache entry that is not used in
an index. Returns cache entry with
empty fields.
discard_cache_entry: A single function that knows how to discard a cache
entry regardless of how it was allocated.

This should make these functions easier to find and cache.h less
overwhelming to read.
In particular, this moves:
- read_object_file
- oid_object_info
- write_object_file
As a result, most of the codebase needs to #include object-store.h.
In this patch the #include is only added to files that would fail to
compile otherwise. It would be better to #include wherever
identifiers from the header are used. That can happen later
when we have better tooling for it.

handle_change_delete() has a block of code displaying one of four nearly
identical messages. Each contains about half a dozen variable
interpolations, which use nearly identical variables as well. Someone
trying to parse this may be slowed down trying to parse the differences
and why they are here; help them out by adding a comment explaining the
differences.
Further, point out that this code structure isn't collapsed into something
more concise and readable for the programmer, because we want to keep full
messages intact in order to make translators' jobs much easier.

These functions were added because processing of these conflicts needed
to be deferred until process_entry() in order to get D/F conflicts and
such right. The number of these has grown over time, and now include
some whose name is misleading:
* conflict_rename_normal() is for handling normal file renames; a
typical rename may need content merging, but we expect conflicts
from that to be more the exception than the rule.
* conflict_rename_via_dir() will not be a conflict; it was just an
add that turned into a move due to directory rename detection.
(If there was a file in the way of the move, that would have been
detected and reported earlier.)
* conflict_rename_rename_2to1 and conflict_rename_add (the latter
of which doesn't exist yet but has been submitted before and I
intend to resend) technically might not be conflicts if the
colliding paths happen to match exactly.
Rename this family of functions to handle_rename_*().
Also rename handle_renames() to detect_and_process_renames() both to make
it clearer what it does, and to differentiate it as a pre-processing step
from all the handle_rename_*() functions which are called from
process_entry().

We had an enum of rename types which included RENAME_DIR; this name felt
misleading since it was not about an entire directory but was a status for
each individual file add that occurred within a renamed directory.
Since this type is for signifying that the files in question were being
renamed due to directory rename detection, rename this enum value to
RENAME_VIA_DIR.
Make a similar change to the conflict_rename_dir() function, and add a
comment to the top of that function explaining its purpose (it may not be
quite as obvious as for the other conflict_rename_*() functions).

We have to convert all of the alloc functions at once, because alloc_report
uses a funky macro for reporting. It is better for the sake of mechanical
conversion to convert multiple functions at once rather than changing the
structure of the reporting function.
We record all memory allocation in alloc.c, and free them in
clear_alloc_state, which is called for all repositories except
the_repository.

This is a small mechanical change; it doesn't change the
implementation to handle repositories other than the_repository yet.
Use a macro to catch callers passing a repository other than

The strings allocated in `setup_unpack_trees_porcelain()` are never
freed. Provide a function `clear_unpack_trees_porcelain()` to do so and
call it where we use `setup_unpack_trees_porcelain()`. The only
non-trivial user is `unpack_trees_start()`, where we should place the
new call in `unpack_trees_finish()`.
We keep the string pointers in an array, mixing pointers to static
memory and memory that we allocate on the heap. We also keep several
copies of the individual pointers. So we need to make sure that we do
not free what we must not free and that we do not double-free. Let a
separate argv_array take ownership of all the strings we create so that
we can easily free them.
Zero the whole array of string pointers to make sure that we do not
leave any dangling pointers.
Note that we only take responsibility for the memory allocated in
`setup_unpack_trees_porcelain()` and not any other members of the
`struct unpack_trees_options`.

Rename `git_merge_trees()` to `unpack_trees_start()` and extract the
call to `discard_index()` into a new function `unpack_trees_finish()`.
As a result, these are called early resp. late in `merge_trees()`,
making the resource handling clearer. A later commit will expand on
that, teaching `..._finish()` to free more memory. (So rather than
moving the FIXME-comment, just drop it, since it will be addressed soon
enough.)
Also call `..._finish()` when `merge_trees()` returns early.

By code restructuring of submodule merge in merge-recursive,
informational messages from the codepath are now given using the
same mechanism as other output, and honor the merge.verbosity
configuration. The code also learned to give a few new messages
when a submodule three-way merge resolves cleanly when one side
records a descendant of the commit chosen by the other side.

In a later patch we want to improve submodule merging by using the output()
function in merge-recursive.c for submodule merges to deliver a consistent
UI to users.
To do so we could either make the output() function globally available
so we can use it in submodule.c#merge_submodule(), or we could integrate
the submodule merging into the merging code. Choose the later as we
generally want to move submodules closer into the core.
Therefore we move any function related to merging submodules
(merge_submodule(), find_first_merges() and print_commit) to
merge-recursive.c. We'll keep add_submodule_odb() in submodule.c as it
is used by other submodule functions. While at it, add a TODO note that
we do not really like the function add_submodule_odb().
This commit is best viewed with --color-moved.

In d8193743e08 (usage.c: add BUG() function, 2017-05-12), a new macro
was introduced to use for reporting bugs instead of die(). It was then
subsequently used to convert one single caller in 588a538ae55
(setup_git_env: convert die("BUG") to BUG(), 2017-05-12).
The cover letter of the patch series containing this patch
(cf 20170513032414.mfrwabt4hovujde2@sigill.intra.peff.net) is not
terribly clear why only one call site was converted, or what the plan
is for other, similar calls to die() to report bugs.
Let's just convert all remaining ones in one fell swoop.
This trick was performed by this invocation:
sed -i 's/die("BUG: /BUG("/g' $(git grep -l 'die("BUG' \*.c)
