The circuit breaker tracked lastFailureTime as time.Time, which was
written in recordFilerFailure and read in shouldSkipUnhealthyFiler
without synchronization, causing a data race.
Data race scenario:
Goroutine 1: recordFilerFailure(0)
health.lastFailureTime = time.Now() // ❌ unsynchronized write
Goroutine 2: shouldSkipUnhealthyFiler(0)
time.Since(health.lastFailureTime) // ❌ unsynchronized read
→ RACE DETECTED by -race detector
Fix:
Changed lastFailureTime from time.Time to int64 (lastFailureTimeNs)
storing Unix nanoseconds for atomic access:
Write side (recordFilerFailure):
atomic.StoreInt64(&health.lastFailureTimeNs, time.Now().UnixNano())
Read side (shouldSkipUnhealthyFiler):
lastFailureNs := atomic.LoadInt64(&health.lastFailureTimeNs)
if lastFailureNs == 0 { return false } // Never failed
lastFailureTime := time.Unix(0, lastFailureNs)
time.Since(lastFailureTime) > 30*time.Second
Benefits:
- Atomic reads/writes (no data race)
- Efficient (int64 is 8 bytes, always atomic on 64-bit systems)
- Zero value (0) naturally means "never failed"
- No mutex needed (lock-free circuit breaker)
Note: sync/atomic was already imported for failureCount, so no new
import needed.
