• File .github/workflows/race.yml — part of check-in [43df2fd2c2] at 2026-10-26 00:59:23 on branch fix/conformance-subtest-t — test(conformance): hand each case its subtest's t; cancel stale Race runs

  check runs each case as a subtest, but the suites passed the case the parent's t, captured in a closure. A fixture that skips or fails, as the fossil-built R-card fixture skips when fossil(1) is absent, then called SkipNow or FailNow on the parent from inside the subtest, which Go fails as "subtest may have called FailNow on a parent test". The Race workflow installs no fossil and failed this way in TestSparseCone. check now hands conforms the subtest's t, and all 150 call sites take it, so a case's skip or failure ends that case alone. TestCheckSkipEndsOnlyTheCase guards the harness.

  A Race run takes most of an hour and merges land faster, so a new run on a ref now cancels the older one. (user: [email protected], size: 1262) [annotate] [blame] [check-ins using] [more...]

name: Race

# The unit suite under the race detector. Sync, the content cache and the
# checkout observer are used from several goroutines at once, and a data race
# there corrupts a repository without failing any ordinary test. The suite
# takes several times as long under -race as without, so it runs after each
# merge to main and nightly, not as a gate on every pull request, which must
# already be up to date with main before it merges.
#
# Fossil and zit are not installed: the tests that compare against them are
# interop checks, which the Tests workflow runs, and skip here.
