我们会对bug 评价4个等级(不会奖励人民币，等值虚拟资产)。只有影响现有在线运行系统的，并且会产生严重分叉等行为的，才会评价为 L3

Building from source

环境要求: Go 1.19+

编译:

git clone https://github.com/33cn/chain33.git $GOPATH/src/github.com/33cn/chain33
cd $GOPATH/src/github.com/33cn/chain33
//国内用户需要导入一下代理
export GOPROXY=https://mirrors.aliyun.com/goproxy
make

 注意：国内用户需要加一下阿里云代理，用于获取依赖包， mod功能已经在Makefile默认开启了

测试：

$ make test

运行

通过这个命令可以运行一个单节点到环境，可以用于开发测试

$ chain33 -f chain33.toml

使用chain33 开发插件注意点

不可以使用 master 分支，要使用发布分支

贡献代码

我们先说一下代码贡献的细节流程，这些流程可以不看，用户可以直接看我们贡献代码简化流程

细节过程

如果有什么想法，建立 issues, 和我们来讨论。
首先点击右上角的 fork 图标，把chain33 fork 到自己的分支比如我的是 vipwzw/chain33
git clone https://github.com/vipwzw/chain33.git $GOPATH/src/github.com/33cn/chain33

注意：这里要 clone 到 $GOPATH/src/github.com/33cn/chain33, 否则go 包路径会找不到

添加 33cn/chain33 远端分支： git remote add upstream https://github.com/33cn/chain33.git 我已经把这个加入了 Makefile 可以直接运行 make addupstream
保持 33cn/chain33 和 vipwzw/chain33 master 分支的同步，可以直接跑 make sync , 或者执行下面的命令

git fetch upstream
git checkout master
git merge upstream/master

注意：不要去修改 master 分支，这样，master 分支永远和upstream/master 保持同步

从最新的33cn/chain33代码建立分支开始开发

git fetch upstream
git checkout master
git merge upstream/master
git branch -b "fixbug_ci"

开发完成后, push 到 vipwzw/chain33

git fetch upstream
git checkout master
git merge upstream/master
git checkout fixbug_ci
git merge master
git push origin fixbug_ci

然后在界面上进行pull request

简化流程

准备阶段

首先点击右上角的 fork 图标，把chain33 fork 到自己的分支比如我的是 vipwzw/chain33
git clone https://github.com/vipwzw/chain33.git $GOPATH/src/github.com/33cn/chain33

注意：这里要 clone 到 $GOPATH/src/github.com/33cn/chain33, 否则go 包路径会找不到

make addupstream

开始开发：这个分支名称自己设置

make branch b=mydevbranchname

开发完成: push

make push b=mydevbranchname m="这个提交的信息"

如果m不设置，那么不会执行 git commit 的命令

修改别人的pull requset

比如我要修改 name=libangzhu branch chain33-p2p-listenPort 的pr

step1: 拉取要修改的分支

make pull name=libangzhu b=chain33-p2p-listenPort

然后修改代码，修改完成后,并且在本地commit

step2: push已经修改好的内容

make pullpush name=libangzhu b=chain33-p2p-listenPort
