When the "ab/various-leak-fixes" topic was merged in [1] only t6021 would fail if the tests were run in the "GIT_TEST_PASSING_SANITIZE_LEAK=check" mode, i.e. to check whether we marked all leak-free tests with "TEST_PASSES_SANITIZE_LEAK=true". Since then we've had various tests starting to pass under SANITIZE=leak. Let's mark those as passing, this is when they started to pass, narrowed down with "git bisect": - t5317-pack-objects-filter-objects.sh: Infaebba436e
(list-objects-filter: plug pattern_list leak, 2022-12-01). - t3210-pack-refs.sh, t5613-info-alternate.sh, t7403-submodule-sync.sh: In189e97bc4b
(diff: remove parseopts member from struct diff_options, 2022-12-01). - t1408-packed-refs.sh: Inab91f6b7c4
(Merge branch 'rs/diff-parseopts', 2022-12-19). - t0023-crlf-am.sh, t4152-am-subjects.sh, t4254-am-corrupt.sh, t4256-am-format-flowed.sh, t4257-am-interactive.sh, t5403-post-checkout-hook.sh: Ina658e881c1
(am: don't pass strvec to apply_parse_options(), 2022-12-13) - t1301-shared-repo.sh, t1302-repo-version.sh: Inb07a819c05
(reflog: clear leftovers in reflog_expiry_cleanup(), 2022-12-13). - t1304-default-acl.sh, t1410-reflog.sh, t5330-no-lazy-fetch-with-commit-graph.sh, t5502-quickfetch.sh, t5604-clone-reference.sh, t6014-rev-list-all.sh, t7701-repack-unpack-unreachable.sh: Inb0c61be320
(Merge branch 'rs/reflog-expiry-cleanup', 2022-12-26) - t3800-mktag.sh, t5302-pack-index.sh, t5306-pack-nobase.sh, t5573-pull-verify-signatures.sh, t7612-merge-verify-signatures.sh: In69bbbe484b
(hash-object: use fsck for object checks, 2023-01-18). - t1451-fsck-buffer.sh: In8e4309038f
(fsck: do not assume NUL-termination of buffers, 2023-01-19). - t6501-freshen-objects.sh: Inabf2bb895b

# This test covers the handling of objects which might have old
|
|
# mtimes in the filesystem (because they were used previously)
|
|
# and are just now becoming referenced again.
|
|
#
|
|
# We're going to do two things that are a little bit "fake" to
|
|
# help make our simulation easier:
|
|
#
|
|
# 1. We'll turn off reflogs. You can still run into
|
|
# problems with reflogs on, but your objects
|
|
# don't get pruned until both the reflog expiration
|
|
# has passed on their references, _and_ they are out
|
|
# of prune's expiration period. Dropping reflogs
|
|
# means we only have to deal with one variable in our tests,
|
|
# but the results generalize.
|
|
#
|
|
# 2. We'll use a temporary index file to create our
|
|
# works-in-progress. Most workflows would mention
|
|
# referenced objects in the index, which prune takes
|
|
# into account. However, many operations don't. For
|
|
# example, a partial commit with "git commit foo"
|
|
# will use a temporary index. Or they may not need
|
|
# an index at all (e.g., creating a new commit
|
|
# to refer to an existing tree).
