Annoucement:

• ServiceComb mesher is able to run as a API gateway to expose service API, see https://mesher.readthedocs.io/en/latest/configurations/edge.html. not just exposing, mesher has all the ability that go chassis has, for example you can acheive blue grean release, or use circuit breaker to protect all the upstream services

Feature:

• go chassis support ServiceComb kie as config server, user can manage configuration in kie server , see https://github.com/go-chassis/go-chassis-config

improvement:

• reduce mem allocation, handler chain must be stateless, so do not implement a handler which has states in chain
• refactor route rule configuration, compatible with old one. we recommand using new rule to manage traffic and use servicecomb kie to manage configuration

bug fix:

• return err is discovery service is diabled.

feature:

• rest api UT support handler chain injection
• route group can add prefix api path to apis
• directly register function to rest route instead of function name string

improvement:

• write structured log info, if lager.yaml is not exist

bug fix:

• #673
• use secure pseudo-random number to generate session id

improvement:

• get timeout from archaius framework runtime
• support new env for sc and cc address

bug fix:

• should monitor address reachable, only if you service center is not behind a load balancing service
• can not load configuration from CSE

bugfix:

• UT solution for rest api doen't works as expectation
• use unified address pool for service center client #650
• return 406 if Produces not been defined but Accept exist in request headers #660

imcompatible feature:

• github.com/rcrowley/go-metrics is removed forever, use pkg/metrics to replace, it curently only support prometheus
• stop supporting apollo server, will integrate with serviceomb-kie in next release

improvement:

• use crypto/rand to generate session id

bug fix:

• log level check

NOTICE

we removed apollo support, and no longer mantain apollo plugin, will integrate with servicecomb-kie in feature release

Features:

• restful api can be tested in UT https://github.com/go-chassis/go-chassis/commit/2fe7b01d49fd74129be40257865ad2847ffc8be2
• able to isolate the instance https://github.com/go-chassis/go-chassis/commit/4155989f43b91e8d7fb874357fc4f122fb39c6d6

• compatible with old version to get source micro service name
• upgrade archaius to support env include underscore

improvment:

• support different protocols specify different handler chains doc
• request body limit

bug fix:

• bug fix: provider con not get source micro service name

modified and improvments

• if resp is nil， should return http status
• Add schema generation success log
• move http handler to prom package (#607)
• export HTTP_DEBUG=1 to enable http tracing to service center

bug fix:

• can not use service level timeout (#598)
• cannot limit flow between go-chassis and java-chassis
• can not register the same prefix protocol (#608)
• operationID should be ResourceFuncName
• schema can not upload to service-center when first registration

Incompatible:
if you use grpc and highway, you have to change your import path to https://github.com/go-chassis/go-chassis-protocol

go chassis is growing bigger due to more plugins, you can see it through our go.mod file, so we decide to move some dependency such as grpc,highway out of this repository. sorry for the inconvenience to you current project,

please check grpc example again to know the changes https://github.com/go-chassis/go-chassis-examples/tree/master/grpc

New feature:

• Log level can be changed in runtime.
• rest api document gen support header definition
• able to read query param into a struct pointer automatically

Bug fix:

• retry did not return error

Improvements

• close client for dead instance
• decouple httpclient and security pkg
• support INTERNAL_IP placeholder in microservice.yaml to report ip as hostname
• chassis.Run now could return error

Features

• expose API to get config center endpoint
• support random port to start server
• support custom server instance status
• support custom max idle conn for http client

Fix bugs:

• dynamic timeout config does not work

NOTICE: if you have custom Loadbalancing Strategy of go chassis before, you need to adjust your implementation to new strategy interface. https://github.com/go-chassis/go-chassis/commit/6cd393ddbb4221c9fd0e2cb64ad30af1ad818fa3
