The code to compute the commit-graph has been taught to use a more
robust way to tell if two object directories refer to the same
thing.
* tb/commit-graph-object-dir:
commit-graph.h: use odb in 'load_commit_graph_one_fd_st'
commit-graph.c: remove path normalization, comparison
commit-graph.h: store object directory in 'struct commit_graph'
commit-graph.h: store an odb in 'struct write_commit_graph_context'
t5318: don't pass non-object directory to '--object-dir'

The index-pack code now diagnoses a bad input packstream that
records the same object twice when it is used as delta base; the
code used to declare a software bug when encountering such an
input, but it is an input error.

The code to automatically shrink the fan-out in the notes tree had
an off-by-one bug, which has been killed.

The way "git submodule status" reports an initialized but not yet
populated submodule has not been reimplemented correctly when a
part of the "git submodule" command was rewritten in C, which has
been corrected.

t7400: testcase for submodule status on unregistered inner git repos
submodule: fix status of initialized but not cloned submodules
t7400: add a testcase for submodule status on empty dirs

The diff-* plumbing family of subcommands now pay attention to the
diff.wsErrorHighlight configuration, which has been ignored before;
this allows "git add -p" to also show the whitespace problems to
the end user.

"git rebase -i" identifies existing commits in its todo file with
their abbreviated object name, which could become ambigous as it
goes to create new commits, and has a mechanism to avoid ambiguity
in the main part of its execution. A few other cases however were
not covered by the protection against ambiguity, which has been
corrected.
* js/rebase-i-with-colliding-hash:
rebase -i: also avoid SHA-1 collisions with missingCommitsCheck
rebase -i: re-fix short SHA-1 collision
parse_insn_line(): improve error message when parsing failed

A new version of fsmonitor-watchman hook has been introduced, to
avoid races.
* kw/fsmonitor-watchman-racefix:
fsmonitor: update documentation for hook version and watchman hooks
fsmonitor: add fsmonitor hook scripts for version 2
fsmonitor: handle version 2 of the hooks that will use opaque token
fsmonitor: change last update timestamp on the index_state to opaque token

"git grep --no-index" should not get affected by the contents of
the .gitmodules file but when "--recurse-submodules" is given or
the "submodule.recurse" variable is set, it did. Now these
settings are ignored in the "--no-index" mode.

Running "git rm" on a submodule failed unnecessarily when
.gitmodules is only cache-dirty, which has been corrected.

Disambiguation logic to tell revisions and pathspec apart has been
tweaked so that backslash-escaped glob special characters do not
count in the "wildcards are pathspec" rule.
* jk/escaped-wildcard-dwim:
verify_filename(): handle backslashes in "wildcards are pathspecs" rule

To make this test work with SHA-256, compute two of the items in the
conflicted index entry. The other entry is a conflict within a conflict
and computing it is difficult, so use test_oid_cache to specify the
proper values for both hash algorithms.

This test used an object ID which was 40 hex characters in length,
causing the test not only not to pass, but to hang, when run with
SHA-256 as the hash. Change this value to a fixed dummy object ID using
test_oid_init and test_oid.
Furthermore, ensure we extract an object ID of the appropriate length
using cut with fields instead of a fixed length.

This test contains a large number of data files, mostly using the same

test files, keep the test files using SHA-1 and translate them on the

algorithm in use.

In this test, there are two main types of object IDs we see in the
diffs: the ones for the submodules, which we care about, and the ones
for the individual files, which are unrelated to what we're testing.
Much of the test already computes the former, so extend the rest of the
test to do so as well. Add a diff comparison function that normalizes
the differences in the latter, since they're not explicitly what we're
testing.

This test produces a large number of diff formats and compares the
output with test files that have content specific to SHA-1. Since we are
more interested in the format of the diffs, and not their specific
values, which are tested elsewhere, add a function which uses sed to
transform these specific object IDs into generic ones of the right size,
which we can then compare.

When we're resolving a REF_DELTA, we compare-and-swap its type from
REF_DELTA to whatever real type the base object has, as discussed in
ab791dd138 (index-pack: fix race condition with duplicate bases,
2014-08-29). If the old type wasn't a REF_DELTA, we consider that a
BUG(). But as discussed in that commit, we might see this case whenever
we try to resolve an object twice, which may happen because we have
multiple copies of the base object.
So this isn't a bug at all, but rather a sign that the input pack is
broken. And indeed, this case is triggered already in t5309.5 and
t5309.6, which create packs with delta cycles and duplicate bases. But
we never noticed because those tests are marked expect_failure.
Those tests were added by b2ef3d9ebb (test index-pack on packs with
recoverable delta cycles, 2013-08-23), which was leaving the door open
for cases that we theoretically _could_ handle. And when we see an
already-resolved object like this, in theory we could keep going after
confirming that the previously resolved child->real_type matches
base->obj->real_type. But:
- enforcing the "only resolve once" rule here saves us from an
infinite loop in other parts of the code. If we keep going, then the
delta cycle in t5309.5 causes us to loop infinitely, as
find_ref_delta_children() doesn't realize which objects have already
been resolved. So there would be more changes needed to make this
case work, and in the meantime we'd be worse off.
- any pack that triggers this is broken anyway. It either has a
duplicate base object, or it has a cycle which causes us to bring in
a duplicate via --fix-thin. In either case, we'd end up rejecting
the pack in write_idx_file(), which also detects duplicates.
So the tests have little value in documenting what we _could_ be doing
(and have been neglected for 6+ years). Let's switch them to confirming
that we handle this case cleanly (and switch out the BUG() for a more
informative die() so that we do so).
