Method callAPIAndRetry

bridge/github/client.go:93–118

callAPIAndRetry calls the Github GraphQL API (indirectly through callAPIDealWithLimit) and in case of error it repeats the request to the Github API. The parameter `apiCall` is intended to be a closure containing a query or a mutation to the Github GraphQL API.

(ctx context.Context, apiCall func(context.Context) error, rateLimitEvent func(msg string))

// case of error it repeats the request to the Github API. The parameter `apiCall` is intended to be
// a closure containing a query or a mutation to the Github GraphQL API.
func (c *rateLimitHandlerClient) callAPIAndRetry(ctx context.Context, apiCall func(context.Context) error, rateLimitEvent func(msg string)) error {
	var err error
	if err = c.callAPIDealWithLimit(ctx, apiCall, rateLimitEvent); err == nil {
		return nil
	}
	// failure; the reason may be temporary network problems or internal errors
	// on the github servers. Internal errors on the github servers are quite common.
	// Retry
	retries := 3
	for i := 0; i < retries; i++ {
		// wait a few seconds before retry
		sleepTime := time.Duration(8*(i+1)) * time.Second
		timer := time.NewTimer(sleepTime)
		select {
		case <-ctx.Done():
			stop(timer)

		case <-timer.C:
			err = c.callAPIDealWithLimit(ctx, apiCall, rateLimitEvent)
			if err == nil {
				return nil

	return err
}

// callAPIDealWithLimit calls the Github GraphQL API and if the Github API returns a rate limiting
// error, then it waits until the rate limit is reset, and it repeats the request to the API. The
