The list-objects-filter code has two steps to its initialization:
1. parse_list_objects_filter() makes sure the spec is a filter we know
about and is syntactically correct. This step is done by "rev-list"
or "upload-pack" that is going to apply a filter, but also by "git
clone" or "git fetch" before they send the spec across the wire.
2. list_objects_filter__init() runs the type-specific initialization
(using function pointers established in step 1). This happens at
the start of traverse_commit_list_filtered(), when we're about to
actually use the filter.
It's a good idea to parse as much as we can in step 1, in order to catch
problems early (e.g., a blob size limit that isn't a number). But one
thing we _shouldn't_ do is resolve any oids at that step (e.g., for
sparse-file contents specified by oid). In the case of a fetch, the oid
has to be resolved on the remote side.
The current code does resolve the oid during the parse phase, but
ignores any error (which we must do, because we might just be sending
the spec across the wire). This leads to two bugs:
- if we're not in a repository (e.g., because it's git-clone parsing
the spec), then we trigger a BUG() trying to resolve the name
- if we did hit the error case, we still have to notice that later and
bail. The code path in rev-list handles this, but the one in
upload-pack does not, leading to a segfault.
We can fix both by moving the oid resolution into the sparse-oid init
function. At that point we know we have a repository (because we're
about to traverse), and handling the error there fixes the segfault.
As a bonus, we can drop the NULL sparse_oid_value check in rev-list,
since this is now handled in the sparse-oid-filter init function.

We test in t5317 that "sparse:oid" filters work with rev-list, but
there's no coverage at all confirming that they work with a fetch or
clone (and in fact, there are several bugs). Let's do a basic test that
a clone fetches the correct objects.
[jk: extracted from Jon's earlier fix patches. I also simplified the
setup down to a single sparse file, and I added checks that we got the
right blobs]

Test & perf scripts must use unique numeric prefix, but a pair
shared the same number, which is fixed here.
* jk/perf-no-dups:
t/perf: rename duplicate-numbered test script
Compilation fix.
* rs/nedalloc-fixlets:
nedmalloc: avoid compiler warning about unused value
nedmalloc: do assignments only after the declaration section
The first line of verbose output from each test piece now carries
the test name and number to help scanning with eyeballs.

t0000-basic: use realistic test script names in the verbose tests
The code to write commit-graph over given commit object names has
been made a bit more robust.
* sg/commit-graph-validate:
commit-graph: error out on invalid commit oids in 'write --stdin-commits'
commit-graph: turn a group of write-related macro flags into an enum
t5318-commit-graph: use 'test_expect_code'
"git checkout" and "git restore" to re-populate the index from a
tree-ish (typically HEAD) did not work correctly for a path that
was removed and then added again with the intent-to-add bit, when
the corresponding working tree file was empty. This has been
corrected.
* vn/restore-empty-ita-corner-case-fix:
restore: add test for deleted ita files
checkout.c: unstage empty deleted ita files
"git pack-refs" can lose refs that are created while running, which
is getting corrected.
* sc/pack-refs-deletion-racefix:
pack-refs: always refresh after taking the lock file
Test fix.
* sg/do-not-skip-non-httpd-tests:
t: warn against adding non-httpd-specific tests after sourcing 'lib-httpd'
t5703: run all non-httpd-specific tests before sourcing 'lib-httpd.sh'
t5510-fetch: run non-httpd-specific test before sourcing 'lib-httpd.sh'
Codepaths to walk tree objects have been audited for integer
overflows and hardened.
* jk/tree-walk-overflow:
tree-walk: harden make_traverse_path() length computations
tree-walk: add a strbuf wrapper for make_traverse_path()
tree-walk: accept a raw length for traverse_path_len()
tree-walk: use size_t consistently
tree-walk: drop oid from traverse_info
setup_traverse_info(): stop copying oid
"git grep --recurse-submodules" that looks at the working tree
files looked at the contents in the index in submodules, instead of
files in the working tree.

To avoid data loss, 'git worktree remove' refuses to delete a worktree
if it's dirty or contains untracked files. However, the error message
only mentions that the worktree "is dirty", even if the worktree in
question is in fact clean, but contains untracked files:
$ git worktree add test-worktree
Preparing worktree (new branch 'test-worktree')
HEAD is now at aa53e60 Initial
$ >test-worktree/untracked-file
$ git worktree remove test-worktree/
fatal: 'test-worktree/' is dirty, use --force to delete it
$ git -C test-worktree/ diff
$ git -C test-worktree/ diff --cached
$ # Huh? Where are those dirty files?!
Clarify this error message to say that the worktree "contains modified
or untracked files".

The grammar for commits used a '?' rather than a '*' on the `merge`
directive line, despite the fact that the code allows multiple `merge`
directives in order to support n-way merges. In fact, elsewhere in
git-fast-import.txt there is an explicit declaration that "an unlimited
number of `merge` commands per commit are permitted by fast-import".
Fix the grammar to match the intent and implementation.

There are two perf scripts numbered p5600, but with otherwise different
names ("clone-reference" versus "partial-clone"). We store timing
results in files named after the whole script, so internally we don't
get confused between the two. But "aggregate.perl" just prints the test
number for each result, giving multiple entries for "5600.3". It also
makes it impossible to skip one test but not the other with
GIT_SKIP_TESTS.
Let's renumber the one that appeared later (by date -- the source of the
problem is that the two were developed on independent branches). For the
non-perf test suite, our test-lint rule would have complained about this
when the two were merged, but t/perf never learned that trick.

Inspired by 21416f0a07 ("restore: fix typo in docs", 2019-08-03), I ran
"git grep -E '(\b[a-zA-Z]+) \1\b' -- Documentation/" to find other cases
where words were duplicated, e.g. "the the", and in most cases removed
one of the repeated words.
There were many false positives by this grep command, including
deliberate repeated words like "really really" or valid uses of "that
that" which I left alone, of course.
I also did not correct any of the legitimate, accidentally repeated
words in old RelNotes.
