Fixes #391
Motivation
When
connectionFailed
is called, no matter if the result is retryable the creation of producer or consumer will fail without retry.Modifications
Check if the result is retryable in
connectionFailed
forProducerImpl
andConsumerImpl
and only fail for non-retryable errors or the timeout error. Register another timer inHandlerBase
to propagate the timeout error toconnectionFailed
.Add
testRetryUntilSucceed
,testRetryTimeout
,testNoRetry
to verify client could retry according to the result returned byClientImpl::getConnection
.
