Replace bare grep with test_grep in test assertions across the
suite, including sourced test helpers (lib-*.sh, *-tests.sh).
test_grep prints the contents of the file being searched on
failure, making debugging easier than a bare grep which fails
silently.
Only assertion-style greps are converted: grep used as a filter
in pipelines, command substitutions, conditionals, or with
redirected I/O is left as-is with a "# lint-ok" annotation.
Existing '! test_grep' calls are rewritten to 'test_grep !' so
that the diagnostic output is preserved on failure.
test_grep requires the file it reads to exist, so '! grep'
assertions that inspect a file whose presence is conditional need
care. In t5537 the '.git/shallow' file is still present after the
repack (the client remains shallow), so the assertion is
converted like any other. In t1400 the '.git/packed-refs' file
exists only with the files backend, so its check is guarded with a
REFFILES prerequisite; the backend-agnostic 'git show-ref' check
that follows still runs under every backend. In t7450 'git~2' is
the NTFS 8.3 short name of a '..git' file and only exists
when 8.3 short-name generation is enabled, so its check is guarded
with a 'test -f' on the path and uses test_grep inside the guard,
the same shape as t1400 (a plain test_grep would BUG when the
short name is absent).
The conversion was generated using a grep-assertion linter
(greplint.pl, added in the following commit) to identify bare
grep calls at command position. To reproduce, from the t/
directory:
# Step 1: annotate the two data-filter greps (grep produces
# data, not a verdict) so the linter skips them.
sed -i '/grep -vf before commits\.raw/s/$/ # lint-ok: data filter/' \
t5326-multi-pack-bitmaps.sh
sed -i '/grep -E "^\[0-9a-f\].*|| :/s/$/ # lint-ok: data filter/' \
t5702-protocol-v2.sh
# Step 1b: two '! grep' assertions need more than a mechanical
# conversion; handle them by hand before the linter-driven steps
# below so it leaves them alone.
#
# t1400: '.git/packed-refs' is absent under reftable, so guard the
# check with REFFILES (a plain test_grep would BUG on the missing
# file):
#
# git update-ref -d HEAD $B &&
# - ! grep "$m" .git/packed-refs &&
# + if test_have_prereq REFFILES
# + then
# + test_grep ! "$m" .git/packed-refs
# + fi &&
# test_must_fail git show-ref --verify -q $m
#
# t7450: git~2 is an NTFS 8.3 short name that exists only when
# short-name generation is enabled, so guard the check on its
# presence with 'test -f' and note in a comment why the path can
# be absent (a plain test_grep would BUG when it is):
#
# - ! grep gitdir squatting-clone/d/a/git~2
# + if test -f squatting-clone/d/a/git~2
# + then
# + test_grep ! gitdir squatting-clone/d/a/git~2
# + fi
# Step 2: reorder pre-existing '! test_grep' to 'test_grep !'
# (must come before steps 3-4 so greplint does not see them)
sed -i 's/! test_grep/test_grep !/' t0031-lockfile-pid.sh
sed -i 's/! test_grep/test_grep !/' t5300-pack-object.sh
sed -i 's/! test_grep/test_grep !/' t5319-multi-pack-index.sh
# Step 3: convert '! grep' -> 'test_grep !'
perl greplint.pl *.sh 2>&1 | cut -d: -f1,2 |
while IFS=: read f l; do
sed -i "${l}s/! *grep/test_grep !/" "$f"

The pack-refs tests previously used raw 'test -f' and 'test -e' checks
with negation. Update them to use Git's standard helper function
test_path_is_missing for consistency and clearer failure reporting.
As suggested in review, replaced the negated 'test_path_exists' with
test_path_is_missing to better reflect the expected absence of paths.

Several tests use a pattern that writes to a temporary file like this:
printf "do something with %d\n" $(test_seq <count>) >tmpfile &&
git do-something --stdin <tmpfile
Other tests use test_seq's -f parameter, but still write to a temporary file:
test_seq -f "do something with %d" <count> >input &&
git do-something --stdin <input
Simplify both of these patterns to
test_seq -f "do something with %d" <count> |
git do-something --stdin

In ac0bad0af4 (t0601: refactor tests to be shareable, 2025-09-19), we
refactored 't/t0601-reffiles-pack-refs.sh' to move all of the tests to
't/pack-refs-tests.sh', which became a common test suite which was also
used by 't/t1463-refs-optimize.sh'.
This also moved the 'test_done' directive to 't/pack-refs-tests.sh'.
Which inhibits additional tests from being added to either of the tests.
Let's move the directive out to both the tests, so that we can add
additional specific tests to them. Also the test flow logic shouldn't be
part of tests which can be embedded in other test scripts.

Both the "files" and "reftable" backend store peeled object IDs for
references that point to tags:
- The "files" backend stores the value when packing refs, where each
peeled object ID is prefixed with "^".
- The "reftable" backend stores the value whenever writing a new
reference that points to a tag via a special ref record type.
Both of these backends use `peel_object()` to find the peeled object ID.
But as explained in the preceding commit, that function does not detect
the case where the tag's tagged object and its claimed type mismatch.
The consequence of storing these bogus peeled object IDs is that we're
less likely to detect such corruption in other parts of Git.
git-for-each-ref(1) for example does not notice anymore that the tag is
broken when using "--format=%(*objectname)" to dereference tags.
One could claim that this is good, because it still allows us to mostly
use the tag as intended. But the biggest problem here is that we now
have different behaviour for such a broken tag depending on whether or
not we have its peeled value in the refdb.
Fix the issue by verifying the object type when peeling the object. If
that verification fails we simply skip storing the peeled value in
either of the reference formats.

In preparation for adding tests for the new `git refs optimize` command,
refactor the existing t0601 test suite to make its logic shareable.
Move the core test logic from `t0601-reffiles-pack-refs.sh` into a new
`pack-refs-tests.sh` file. Inside this new script, replace hardcoded
calls to "pack-refs" with the `$pack_refs` variable.
The original `t0601-reffiles-pack-refs.sh` script now becomes a simple
"driver". It is responsible for setting the default value of the
variable and then sourcing the test library.
This new structure follows the established pattern used for sharing
tests between `git-for-each-ref` and `git-refs list` and prepares the
test suite for the `refs optimize` tests to be added in a subsequent
commit.
