Motivation:
We need to ensure we not retain the buffer until readEndOfLine(...) completes as otherwise we may leak memory in the case of an exception.
Modifications:
Only call retain after readEndOfLine(...) returns.
Result:
No more leak in case of exception while decoding redis messages.
Motivation:
- `RedisBulkStringAggregator` raises errors for multiple null bulk strings.
- Null or empty bulk string has no content, but current `RedisDecoder` generates header and contents.
Modifications:
- Fix decoding null bulk string of `RedisDecoder` for `RedisBulkStringAggregator`.
Result:
- Fixes#5184.
