Kitex Release v0.6.0
Introduction to Key Changes
1. GRPC Metainfo Pass Through
The gRPC client sets the header to ctx by default, and external methods can use
GetHeaderMetadataFromCtx to obtain meta information. It can be used to obtain meta information within transmeta and set it to rpcinfo, or to obtain header information within middlewares.
2. Kitex configuration module refactoring
Added config items for retry, circuit breaker, timeout, and flow limiting to support [configmanager] (https://github.com/cloudwego/configmanager) Middleware defined interfaces to support extended integration with external configuration centers.
3. Kitex - Tools
- Support for inserting deep copy function of an object in thrift generation code for deep copying source objects to destination objects. The use method is to add
-deep-copy-apiparameter to the kitex command;
- Support for inserting IDL descriptor registration code into thrift generation code, which is used to register IDL descriptor information into the
github.com/cloudwego/kitex/pkg/reflection/thriftpackage after loading the corresponding generated code at runtime, and obtain descriptor information through the exposed functions. The use method is to add
thriftparameter of kitex command, such as
kitex -thrift generate-reflection-info=true… Kitex only supports IDL descriptor information registration in v1.12.0, richer query interfaces will be released in subsequent versions, and IDL descriptor registration function generation will also be modified to default generation.
1. Refactor the detection server to support detection of multiple protocols
The old version of the detection server only supports http2 as the detection protocol. The v1.12.0 version supports users to pass-in the
remote.ServerTransHandlerFactory corresponding to the
remote.ServerTransHandler which implement
detection.DetectableServerTransHandler interface as indefinite parameters, and cooperate with the default
remote.ServerTransHandler to handle unmatched protocols to achieve a Kitex Server compatible with multiple protocols.
2. Consistency hash
buildVirtualNodes in Kitex consistency hash load balancer uses
virtualFactorLen to initialize a bytes array, and there may be insufficient space to accommodate the VirtualNodeLen number, resulting in the address part being overwritten.
3. Long Connection Pool Metrics
Fix the issue that the records that long connection pool reuses connections successfully didn’t report.
Upgrade netpoll library dependency to v0.4.0 and support for [configmanager] ( https://github.com/cloudwego/configmanager ) v0.2.0.
Full Release Log
- [#923] feat(grpc): grpc client set header and trailer to context by default and provide api to get header from ctx

- [#955] optimize: remove redundant onRead error log in gonet transerver
- [#954] optimize: dont return error when transHandler not implement graceful shutdown
- [#941] optimize(callopt): optimize the debug info of callopt to reduce the possibility of slice grow
- [#963] fix(generic): generic-map writeInt8 fails on byte
- [#901] fix(mux): mux connection asynccallback dont create new goroutine and server wait all crrst packets received by client
- [#921] fix(loadbalance): fix consisthash byte length
- [#922] fix(mux): fix the problem that output unreasonable error when exit if enable mux and use Kitex Protobuf

- [#958] refactor(errorHandler): refactor the definition of error handler to get more information to handle error
- [#943] refactor(client): refactor client.Call to improve readability
- [#560] refactor: refactor server detection trans handler to support custom registration
- [#900] test(generic): add thrift reflection (using dynamicgo) generic call example
