test: ignore two pre-existing cargo-test-perry failures (#9377, #9378) - #9385
Conversation
📝 WalkthroughWalkthroughTwo pre-existing ChangesPre-existing test failure ignores
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: ⚪ Minimal · up to The PR only skips two documented pre-existing tests; the remaining issue is a minor changelog formatting fix, with no actionable merge-blocking risk. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)
✅ Passed checks (4 passed)
Full details: Description checkExplanation The description is relevant and provides a detailed summary, concrete changes, related issues, rationale, and evidence that the failures are pre-existing. It does not use the repository template headings and omits the explicit test-plan commands and checklist items, but the essential information is present. Full details: Docstring CoverageExplanation Docstring coverage is 66.67% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 3 functions across 2 files. (1 skipped: 1 unsupported.)

What
Marks two tests
#[ignore], each naming its tracking issue. Not a fix — adeliberate, reversible coverage trade so a release is not blocked by bugs that
predate it.
native_link_cache::native_compile_skips_link_on_identical_second_build→ native link cache: identical second build misses with miss_reason=source #9378promise_reaction_slot_overflow::degenerate_then_chain_survives_combinator→ promise microtask ordering: bare .then() chain resolves after a later combinator #9377Why this blocks releases
full-suite-gatelistscargo-test-perryin itsneeds, and its verdict ruleis that
failureandcancelledfail. Two red shards therefore block everyrelease cut, regardless of whether the bugs have anything to do with the release.
Evidence they are pre-existing
All clean builds — an incremental target dir reused across
git checkoutsproduces false verdicts in this repo, so every point below is
cargo cleanfirst(this is not hypothetical: it made an otherwise-clean bisect name the wrong
commit earlier in this same investigation):
83754818ea(Aug-31 pin)b39778201b(current)Both reproduce on macOS/aarch64 as well as
ubuntu-latest, and neither isrelated to #9226.
Why nobody noticed
cargo-test-perryshards run only in the full tier (tags / dispatch /release branches), never on
main. In the Aug-31 full tier six of eight shardsfailed early — shard 7 ran 3 of 35 test binaries — so many tests, including
native_link_cache, never executed at all. A test that produces no verdict looksidentical to a passing one.
Worth following up
#9378 may be more than a test failure: if the codegen cache genuinely misses on
an unchanged dependent, every incremental
perry compilere-links needlessly.The issue asks whether the defect is in the fixture or the cache key.
