retry

func BackOff ¶

func BackOff(ctx context.Context, t time.Duration)

BackOff sleeps for the given duration and respects context cancellation.

func CloneRequestForRetry ¶

func CloneRequestForRetry(req *http.Request) (*http.Request, error)

func DoWithApplicationRetry ¶

func DoWithApplicationRetry(
	cfg *shared.Configuration,
	request *http.Request,
) (*http.Response, time.Duration, error)

DoWithApplicationRetry executes an HTTP request with application-level retry logic. This is the shared equivalent of the per-product callAPI method.

Retry behaviour:

• 502/503/504: retries with backoff (skips POST)
• 429: retries honoring Retry-After header, falls back to waitTime
• Other status codes or transport errors: returns immediately
• Respects context cancellation during backoff

Interaction with RoundTripper ¶

client.Do invokes the configured http.RoundTripper, which may be a RoundTripper. When a multi-server Strategy is active, transport-level network errors and status codes listed in FailoverOnStatusCodes are handled by the round tripper before this function sees the response: it either receives a successful response or err != nil after all failover attempts are exhausted.

Status codes NOT in FailoverOnStatusCodes (including the 502/503/504/429 that this function retries on) pass through normally.

Worst-case total attempts: Configuration.MaxRetries × Options.MaxRetries.
