v0.2.0

Added

• Three new checks, enabled by default:
  • hardport — hardcoded TCP/UDP ports in test listeners.
  • maporder — assertions that depend on map-iteration order.
  • eventuallyeffect — count-dependent side effects inside polling callbacks.
• version command: flakylint version (also --version / -version) prints
  the build version, commit, and date, falling back to
  runtime/debug.ReadBuildInfo when built without release ldflags.

Changed

• Autofix safety: suggested fixes are no longer offered when they would corrupt
  the source. httptestclose keeps the diagnostic but drops the fix inside
  if/for/switch statement initializers; exitfatal suppresses its fix when
  the testing receiver name is shadowed at the call site.
• Precision narrowing from corpus evaluation and an external audit:
  hardport validates the network argument and port range and no longer flags
  http.Server{Addr:} literals; eventuallyeffect ignores channels declared
  inside the callback; maporder is now source-order aware and ignores
  per-iteration accumulators used only as testify message arguments.

Upgrade notes

• The new default-enabled checks may surface findings in downstream CI that
  previous versions did not report. Pin @v0.2.0 in CI installs (rather than
  @latest) so a future release does not change results unexpectedly.

v0.1.1

Full Changelog: v0.1.0...v0.1.1

v0.1.0

flakylint v0.1.0 — initial release

Four conservative go/analysis checks for flaky-test patterns in Go:

• httptestclose — httptest.NewServer never closed (leaked port/goroutines); autofix inserts t.Cleanup(srv.Close)
• sleepassert — time.Sleep in a test body instead of synchronization; suggests testing/synctest (Go 1.24+)
• parallelglobal — writes to package-level variables in t.Parallel() tests
• exitfatal — os.Exit / log.Fatal in tests (skips cleanup); autofix rewrites log.Fatal* → t.Fatal*

Field-tested before release: 0 false positives across 104 hand-triaged findings on kubernetes, grafana, prometheus, and testcontainers-go — see docs/corpus.
