After blame has finished but before we produce any output, we coalesce
groups of lines that were adjacent in the original suspect (which may
have been split apart by lines in intermediate commits which went away).
However, this can cause incorrect output if the lines are not also
adjacent in the result. For instance, the case in t8003 has:
ABC
DEF
which becomes
ABC
SPLIT
DEF
Blaming only lines 1 and 3 in the result yields two blame groups (one
for each line) that were adjacent in the original. That's enough for us
to coalesce them into a single group, but that loses information: our
output routines assume they're adjacent in the result as well, and we
output:
<oid> 1) ABC
<oid> 2) SPLIT
This is nonsense for two reasons:
- we were asked about line 3, not line 2; we should not output the
SPLIT line at all
- commit <oid> did not touch the SPLIT line at all! We found the
correct blame for line 3, but the bug is actually in the output
stage, which is showing the wrong line number and content from the
final file.
We can fix this by only coalescing when both the suspect and result
lines are adjacent. That fixes this bug, but keeps coalescing in cases
where want it (e.g., the existing test in t8003 where SPLIT goes away,
and the lines really are adjacent in the result).

In preparation for adding more tests of blame's coalesce code, let's
split the setup out from the first test, and give each of the commits
a more meaningful name:
- $orig for the original source that added the lines
- $split for the version where they are split apart
- $final for the final version that re-joins them
That's not strictly necessary, but makes the follow-on tests less
brittle than relying on HEAD^, etc, to name the commits.

Commit f0cbe742f4 (blame: add a test to cover blame_coalesce(),
2019-06-20) added a test case where blame can usefully coalesce two
groups of lines. But since it relies on the normal blame output, it only
exercises the code and can't tell whether the lines were actually
joined into a single group.
However, by using --porcelain output, we can see how git-blame considers
the groupings (and likewise how the coalescing might have a real
user-visible impact for a tool that uses the porcelain-output
groupings). This lets us confirm that we are indeed coalescing correctly
(and the fact that this test case requires coalescing can be verified by
dropping the call to blame_coalesce(), causing the test to fail).

Convert submodule subcommand 'summary' to a builtin and call it via
'git-submodule.sh'.
The shell version had to call $diff_cmd twice, once to find the modified
modules cared by the user and then again, with that list of modules
to do various operations for computing the summary of those modules.
On the other hand, the C version does not need a second call to
$diff_cmd since it reuses the module list from the first call to do the
aforementioned tasks.
In the C version, we use the combination of setting a child process'
working directory to the submodule path and then calling
'prepare_submodule_repo_env()' which also sets the 'GIT_DIR' to '.git',
so that we can be certain that those spawned processes will not access
the superproject's ODB by mistake.
A behavioural difference between the C and the shell version is that the
shell version outputs two line feeds after the 'git log' output when run
outside of the tests while the C version outputs one line feed in any
case. The reason for this is that the shell version calls log with
'--pretty=format:<fmt>' whose output is followed by two echo
calls; 'format' does not have "terminator" semantics like its 'tformat'
counterpart. So, the log output is terminated by a newline only when
invoked by the user and not when invoked from the scripts. This results
in the one & two line feed differences in the shell version.
On the other hand, the C version calls log with '--pretty=<fmt>'
which is equivalent to '--pretty:tformat:<fmt>' which is then
followed by a 'printf("\n")'. Due to its "terminator" semantics the
log output is always terminated by newline and hence one line feed in
any case.
Also, when we try to pass an option-like argument after a non-option
argument, for instance:
git submodule summary HEAD --foo-bar
(or)
git submodule summary HEAD --cached
That argument would be treated like a path to the submodule for which
the user is requesting a summary. So, the option ends up having no
effect. Though, passing '--quiet' is an exception to this:
git submodule summary HEAD --quiet
While 'summary' doesn't support '--quiet', we don't get an output for
the above command as '--quiet' is treated as a path which means we get
an output only if a submodule whose path is '--quiet' exists.
The error message in case of computing a summary for non-existent
submodules in the C version is different from that of the shell version.
Since the new error message is not marked for translation, change the
'test_i18ngrep' in t7421.4 to 'grep'.

Nonbare repositories are special directories. Unlike normal directories
that we might recurse into to list the files they contain, nonbare
repositories must themselves match and then we always report only on the
nonbare repository directory itself and not on any of its contents.
Separately, when traversing directories to try to find untracked or
excluded files, we often think in terms of paths either matching the
specified pathspec, or not matching them. However, there is a special
value that do_match_pathspec() uses named
MATCHED_RECURSIVELY_LEADING_PATHSPEC which means "this directory does
not match any pathspec BUT it is possible a file or directory underneath
it does." That special value prevents us from prematurely thinking that
some directory and everything under it is irrelevant, but also allows us
to differentiate from "this is a match".
The combination of these two special cases was previously uncovered.
Add a test to the testsuite to cover it, and make sure that we return a
nonbare repository as a non-match if the best match it got was
MATCHED_RECURSIVELY_LEADING_PATHSPEC.

The --batch-size=<size> option of 'git multi-pack-index repack' is
intended to limit the amount of work done by the repack. In the case of
a large repository, this command should repack a number of small
pack-files but leave the large pack-files alone. Most often, the
repository has one large pack-file from a 'git clone' operation and
number of smaller pack-files from incremental 'git fetch' operations.
The issue with '--batch-size' is that it also _prevents_ the repack from
happening if the expected size of the resulting pack-file is too small.
This was intended as a way to avoid frequent churn of small pack-files,
but it has mostly caused confusion when a repository is of "medium"
size. That is, not enormous like the Windows OS repository, but also not
so small that this incremental repack isn't valuable.
The solution presented here is to collect pack-files for repack if their
expected size is smaller than the batch-size parameter until either the
total expected size exceeds the batch-size or all pack-files are
considered. If there are at least two pack-files, then these are
combined to a new pack-file whose size should not be too much larger
than the batch-size.
This new strategy should succeed in keeping the number of pack-files
small in these "medium" size repositories. The concern about churn is
likely not interesting, as the real control over that is the frequency
in which the repack command is run.

t6425 was very picky about the exact output message produced by a
rename/delete conflict, in a way that just scratches the surface of the
mess that was built into merge-recursive. The idea was that it would
try to find the possible combinations of different conflict types, and
when more than one was present for one path, it would try to provide a
combined message that covered all the cases.
There's a lot to unravel here...
First, there's a basic conflict type known as modify/delete, which is a
content conflict. It occurs when one side deletes a file, but the other
modifies it.
There is also a path conflict known as a rename/delete. This occurs
when one side deletes a path, and the other renames it. This is not a
content conflict, it is a path conflict. It will often occur in
combination with a content conflict, though, namely a modify/delete. As
such, these two were often combined.
Another type of conflict that can exist is a directory/file conflict.
For example, one side adds a new file at some path, and the other side
of history adds a directory at the same path. The path that was "added"
could have been put there by a rename, though. Thus, we have the
possibility of a single path being affected by a modify/delete, a
rename/delete, and a directory/file conflict.
In part, this was a natural by-product of merge-recursive's design.
Since it was doing a four way merge with the contents of the working
tree being the fourth factor it had to consider, it had working tree
handling spread all over the code. It also had directory/file conflict
handling spread everywhere through all the other types of conflicts.
And our testsuite has a huge number of directory/file conflict tests
because trying to get them right required modifying so many different
codepaths. A natural outgrowth of this kind of structure is conflict
messages that combine all the different types that the current codepath
is considering.
However, if we want to make the different conflict types orthogonal and
avoid repeating ourselves and getting very brittle code, then we need to
split the messages from these different conflict types apart. Besides,
trying to determine all possible permutations is a _royal_ mess. The
code to handle the rename/delete/directory/file conflict output is
already somewhat hard to parse, and is somewhat brittle. But if we
really wanted to go that route, then we'd have to have special handling
for the following types of combinations:
* rename/add/delete:
on side of history that didn't rename the given file, remove the file
instead and place an unrelated file in the way of the rename
* rename/rename(2to1)/mode conflict/delete/delete:
two different files, one executable and the other not, are renamed
to the same location, each side deletes the source file that the
other side renames
* rename/rename(1to2)/add/add:
file renamed differently on each side of history, with each side
placing an unrelated file in the way of the other
* rename/rename(1to2)/content conflict/file location/(D/F)/(D/F)/:
both sides modify a file in conflicting way, both rename that file
but to different paths, one side renames the directory which the
other side had renamed that file into causing it to possibly need a
transitive rename, and each side puts a directory in the way of the
other's path.
Let's back away from this path of insanity, and allow the different
types of conflicts to be handled by separate pieces of non-repeated code
by allowing the conflict messages to be split into their separate types.
(If multiple conflict types affect a single path, the conflict messages
can be printed sequentially.) Start this path with a simple change:
modify this test to be more flexible and accept the output either merge
backend (recursive or the new ort) will produce.

merge-recursive treats an add/add conflict where one of the adds came
from a rename as a separate 'rename/add' type of conflict. However, if
there is not content conflict after the content merge(s), then the file
is not considered to be conflicted. That suggests the conflict type is
really just add/add. Other merge engines might choose to print messages
to the console that just refer to these as add/add conflicts; accept
both types of output.
Note: it could help to notify users if the three-way content merge of
the rename had content conflicts, because when we then go to two-way
merge THAT with the conflicting add we can get nested conflict markers.
merge-recursive, unfortunately, doesn't do that, but other merge engines
could.

This test had multiple issues causing it to fail for the wrong
reason(s):
* rename/rename(1to2) conflicts have always left the original source
path present in the working directory and index (at stage 1). Thus,
the triple rename/rename(1to2) should result in 9 unstaged files,
not 6.
* It messed up the three-way content merge for checking the results of
merging for one of the renames, accidentally turning it into a
two-way merge.
* It got the contents of the base files it was using to compare
against wrong, due to an off-by-one error, and overwrite-redirection
('>') instead of append-redirection ('>>').
* It used slightly too-long conflict markers
* It didn't include filenames in the conflict marker hunks (granted,
that was a shortcoming of the merge-recursive backend for rename/add
and rename/rename(2to1) conflicts, but since it's
test_expect_failure anyway we might as well make it expect our
preferred behavior rather than some compromise that we can't yet
reach anyway).
Fix these issues so that a merge backend which correctly handles these
kinds of nested conflicts will pass the test.

(I believe this problem arose because earlier incarnations counted lines

The tests for the merge machinery are spread over several places.
Collect them into t64xx for simplicity. Some notes:
t60[234]*.sh:
Merge tests started in t602*, overgrew bisect and remote tracking
tests in t6030, t6040, and t6041, and nearly overtook replace tests
in t6050. This made picking out relevant tests that I wanted to run
in a tighter loop slightly more annoying for years.
t303*.sh:
These started out as tests for the 'merge-recursive' toplevel command,
but did not restrict to that and had lots of overlap with the
underlying merge machinery.
t7405, t7613:
submodule-specific merge logic started out in submodule.c but was
moved to merge-recursive.c in commit 18cfc08866 ("submodule.c: move
submodule merging to merge-recursive.c", 2018-05-15). Since these
tests are about the logic found in the merge machinery, moving these
tests to be with the merge tests makes sense.
t7607, t7609:
Having tests spread all over the place makes it more likely that
additional tests related to a certain piece of logic grow in all those
other places. Much like t303*.sh, these two tests were about the
underlying merge machinery rather than outer levels.
Tests that were NOT moved:
t76[01]*.sh:
Other than the four tests mentioned above, the remaining tests in
t76[01]*.sh are related to non-recursive merge strategies, parameter
parsing, and other stuff associated with the highlevel builtin/merge.c
rather than the recursive merge machinery.
t3[45]*.sh:
The rebase testcases in t34*.sh also test the merge logic pretty
heavily; sometimes changes I make only trigger failures in the rebase
tests. The rebase tests are already nicely coupled together, though,
and I didn't want to mess that up. Similar comments apply for the
cherry-pick tests in t35*.sh.

In `stop_progress()`, we're careful to check that `p_progress` is
non-NULL before we dereference it, but by then we have already
dereferenced it when calling `finish_if_sparse(*p_progress)`. And, for
what it's worth, we'll go on to blindly dereference it again inside
`stop_progress_msg()`.
We could return early if we get a NULL-pointer, but let's go one step
further and BUG instead. The progress API handles NULL just fine, but
that's the NULL-ness of `*p_progress`, e.g., when running with
`--no-progress`. If `p_progress` is NULL, chances are that's a mistake.
For symmetry, let's do the same check in `stop_progress_msg()`, too.

from its non-existent worktree is nonsensical. Therefore, make it an
error to use --separate-git-dir on a bare repository.
Implementation note: "git init" considers a repository bare if told so
explicitly via --bare or if it guesses it to be so based upon
heuristics. In the explicit --bare case, a conflict with
--separate-git-dir is easy to detect early. In the guessed case,
however, the conflict can only be detected once "bareness" is guessed,
which happens after "git init" has begun creating the repository.
Technically, we can get by with a single late check which would cover
both cases, however, erroring out early, when possible, without leaving
detritus provides a better user experience.

Under normal circumstances, if a test author misspells a filename passed
to test_cmp(), the error is quickly discovered when the test fails
unexpectedly due to test_cmp() being unable to find the file. However,
if the test is expected to fail, as with test_expect_failure(), a
misspelled filename as argument to test_cmp() will go unnoticed since
the test will indeed fail, but for the wrong reason. Make it easier for
test authors to discover such problems early by sanity-checking the
arguments to test_cmp(). To avoid penalizing all clients of test_cmp()
in the general case, only check for missing files if the comparison
fails.
While at it, make test_cmp_bin() sanity-check its arguments, as well.

When creating "new file" diffs against i-t-a index entries, diff-lib
erroneously used the mode of the cache entry rather than the mode of the
file in the worktree. This changes run_diff_files() to correctly use the
mode of the worktree file in this case.

apply --cached (as used by add -p) should accept creation and deletion
patches to intent-to-add paths in the index. apply --index, however,
should always fail because an intent-to-add path never matches the
worktree (by definition).
