[jjz921024]

#11449

Motivation:

• Support encode/decode new types introduced by RESP3
• [RESP3](Redis Serialization Protocol 3) specification (https://github.com/antirez/RESP3/blob/master/spec.md)

Modifications:

• Add new types of NullRedisMessage, BooleanRedisMessage

• Add new number types of DoubleRedisMessage, BigNumberRedisMessage

• Add BulkErrorStringHeaderRedisMessage & FullBulkErrorStringRedisMessage for support blob error. (Just extend BulkStringHeaderRedisMessage & FullBulkStringRedisMessage)

• Extract AbstractNumberRedisMessage to unify IntegerRedisMessage & DoubleRedisMessage & BigNumberRedisMessage

• Modify RedisEncoder & RedisDecoder to support new types

• Modify RedisBulkStringAggregator to support blob error message

• Add unit tests

• Fix some typo

• Support encode/decode Set types redis message & Extract Collection redis message for Array types and Set types

• Add RedisMapAggregator for support decode Map types message

• Support Verbatim string and Push types message

• (Todo) support Attribute, Streamed strings and Streamed aggregated data types

Result:

• codec-redis can encode/decode RESP3

private final ?

[jjz921024]

The sub class ArrayRedisMessage and SetRedisMessage need access this children field on the abstract method children() for cast to List<Message> or Set<Message>, so it can't be private? but I had made it final

[normanmaurer]

final

[jjz921024]

Thear are a predefined EMPTY_INSTANCE of SetRedisMessage so that it can't not be final and need a default contructor.
But i not sure the EMPTY_INSTANCE is necessary?

Did we miss this?

Did we miss this

hi, I'm still here and I fix all review. But this module will be removed out of netty?

If netty want to suppor RESP3, what can i do?
