Preserve the fallback for non-positive route timeouts.

cmp.Or retains -0.5 for -500ms, so the ADC route receives an invalid timeout instead of the 60-second fallback. The CRD does not constrain these duration strings, while APISIX requires timeout values greater than zero. Map non-positive durations to the default and preserve positive fractional values.

🐛 Suggested fix 
-import "cmp"
...
 	defaultTimeout := metav1.Duration{Duration: apiv2.DefaultUpstreamTimeout}
+	timeoutSeconds := func(timeout metav1.Duration) float64 {
+		if timeout.Duration <= 0 {
+			return defaultTimeout.Seconds()
+		}
+		return timeout.Seconds()
+	}
 	return &adc.Timeout{
-		Connect: cmp.Or(rule.Timeout.Connect.Seconds(), defaultTimeout.Seconds()),
-		Read:    cmp.Or(rule.Timeout.Read.Seconds(), defaultTimeout.Seconds()),
-		Send:    cmp.Or(rule.Timeout.Send.Seconds(), defaultTimeout.Seconds()),
+		Connect: timeoutSeconds(rule.Timeout.Connect),
+		Read:    timeoutSeconds(rule.Timeout.Read),
+		Send:    timeoutSeconds(rule.Timeout.Send),
 	}

Review comment at @internal/adc/translator/apisixroute.go at line 92:
Update the timeout conversion in the route translation flow to map zero and
negative durations to the default timeout while preserving positive fractional
seconds. Replace the cmp.Or usage for Connect, Read, and Send with a shared
helper near the timeout construction, and remove the cmp dependency if no longer
used.

According to the CRDS type definition, should there be no negative values? Please confirm again.

@AlinsRan I checked again. The current ApisixRoute CRD does not prohibit negative timeout values.

  • In api/v2/apisixroute_types.go, UpstreamTimeout uses metav1.Duration. This type accepts signed durations such as "-500ms".
  • In config/crd/bases/apisix.apache.org_apisixroutes.yaml, Line 328–341, the timeout fields have only type: string. No pattern or CEL rule requires a non-negative value.
  • The admission webhook delegates to ADC validation. However, it allows admission when that validation is unavailable, so it does not guarantee rejection.

Thus, "-500ms" can reach buildTimeout, where cmp.Or(-0.5, 60) returns -0.5.

My original wording was too broad: the old code did not default all negative values. It defaulted negative subsecond values only because integer conversion truncated them to zero. Explicitly rejecting negative durations is also a valid solution; defaulting them is not the only option.

The negative-value concern remains valid, but it is a validation gap rather than a general fallback contract.

You are interacting with an AI system.

Align BackendTrafficPolicy validation with fractional durations.

The test constructs metav1.Duration values of 1500ms and 2500ms directly, but the BackendTrafficPolicy CRD admits only strings matching ^[0-9]+s$. An admitted policy therefore cannot reach this fractional translation path. Timeout is documented as a Kubernetes Duration, and the other upstream timeout resources accept fractional duration strings.

Update the BackendTrafficPolicy validation pattern and regenerate the CRD so the test covers a supported input. Keep the independent 60s default unchanged.

Update the BackendTrafficPolicy timeout validation pattern to accept fractional
Kubernetes duration strings such as 1500ms and 2500ms, while preserving the
independent 60s default behavior. Regenerate the corresponding CRD artifacts so
the validation used by admitted policies matches the fractional translation path
exercised by TestAttachBackendTrafficPolicyToUpstreamPreservesSubsecondValues.
