annchain's Issues

support update and get history

建议说明文档的中文支持

我们现在主要客户还是国人，如果真的用我们的系统，为啥不提供中文文档呢？？？
不说只有中文文档，至少也要提供中文文档吧

docker-compose up failed

远程RPC访问的method方法列表和params

远程RPC访问的method方法列表和params，有文档吗？
目前只测试出一个方法curl -X POST
http://127.0.0.1:46657
-H 'Content-Type: application/json'
-d '{
"jsonrpc":"2.0",
"method":"info",
"params":[],
"id":"1"
}'

Applicathion log need traceId

validator accum don't update

Environment ： 7 nodes（validators）
Version：genesis 1.4.0
Problem: validator accum don't update when block height increase,it means proposer don't change. It's unfair

Tips:
use golang sdk to update validators（remove and add validator）

Smooth upgrade（incompatible version）

Blockchain upgrade has many problems，such as historical data、API compatible with running nodes（you can't stop all nodes for upgrade)

One method of smooth upgrade：
1、client only storage business data（exclude block time、hash value from blockchain），use others database temporary storage historical data，write historical data to new version AnnChain
2、Use others database temporary storage historical data，write historical data to new version AnnChain. Temporary storage should include old version AnnChain information（block time and hash value from blockchain）and new version AnnChain information（block time and hash value from blockchain），one historical business data corresponds to two version AnnChain information，also use new version AnnChain information replace oldversion AnnChain information

账号空间过大导致性能下降

部署了4节点链，进行稳定性测试；测是的合约写，每次call都创建新账号。
在持续了一天之后，性能下降明显，冲500+tps下降到30tps左右；
大约估下，此时的账号空间大约在1000万左右。
另外，重新部署链，预先准备了10万账号，重复使用，测试合约写。测试了一天，tps基本维持在500tps上下。

we need an ACP

To set out more new ideas, I think we need a new community for proposal. Like Annchain community Proposal？

docker-compose only use one image(annchain/genesis:latest).

It means even if the code of AnnChain is updated, the docker-compose uses the previous image（annchain/genesis:latest)

limiting protection

If too many requests(such as more than 2000tps) ask AnnChain，can all requests be executed correctly？

limiting protection limit max count of request per second，requests exceeding the maximum will be discarded（A special response code represents limiting protection）

Audit log

Audit log should includes ：
TraceId、ApiPath or MsgType、ReqContent(Limit length in case content is too long)、RespContent(Limit length in case content is too long)、RespCode（http code）、Duration(endTime - startTime)

evm tx pool waiting queue is full

进行压力测试的时候，用的pendingnonce，账号100个，会出现错误“evm tx pool waiting queue is full”。
简单分析了下出现该错误的情况：
1、waiting queue和pending queue 两个队列，如果pending 队列满了（5000），并且waiting队列满了（5000），那么会出现该错误
2、tx的nonce在pending不连续（nonce断层），会放到waiting中；如果waiting队列满了，会出现该错误。
