v1.0.2

Changelog

• Add rootPath field to go client struct for configuring path prefix when sending http requests
• Add Nacos as another option for service discovery
• Add NacosRRServiceProvider and NacosWRRServiceProvider for supporting load balancing of services fetched from Nacos server
• Fix bug for OpenAPI 3.0 onlinedoc when GDD_ROUTE_ROOT_PATH is set
• Replaced json marshal with msgpack for serializing node meta data, which makes meta data size smaller nearly 40% than json, but the optimization also makes v1.0.2 not compatible with old versions. Please upgrade go-doudou to the latest version if possible.

v0.9.7

1. Fix registry endpoint bug: when a node left and come back, the node's status is still suspect in browser.
2. Add --pre flag to go-doudou svc push subcommand to let developer add prefix string to docker image name.
3. Add a built-in endpoint GET /go-doudou/config to display all environment variable pairs in browser.
4. Add latest release version notify and upgrade feature by go-doudou version command

v0.9.6 Fix incorrectly leave

1. Remove mlist.Leave from registry.Shutdown method because calling leave method will send a left message to remote peers and make its state to be StateLeft. A node won't gossip messages to StateLeft nodes any more. If left a cluster incorrectly by calling leave method, the node won't have any chance to refute suspect or dead message to let remote peers know it still alive (or become alive again).
2. Add another package level method for leaving cluster

// Leave leaves the cluster on purpose
func Leave(timeout time.Duration) {
	if mlist != nil {
		_ = mlist.Leave(timeout)
		logger.Info("local node left the cluster")
	}
}

v0.9.5

1. Optimization: disable memberlist node weight calculation when GDD_MEM_WEIGHT is set to >0
2. Optimization: update openapi doc ui to latest version of go-doudou-openapi-ui with new feature that sidebar menu width can be ajusted

2. Refactored ratelimit package
3. Support configuring rate limit by formatted string, for example: 0.0055 reqs/second with burst 20: "0.0055-S-20"
4. Type of MemoryStore field keys is changed from map to *lru.Cache in order to control memory usage

v0.9.2 Log and ELK stack

Improved log feature for supporting ELK stack better
