## GPG设置

**1. 安装GPG**

在[GnuPG官网](https://www.gnupg.org/download/index.html)下载安装包。
GnuPG的1.x版本和2.x版本的命令有细微差别，下列说明以`GnuPG-2.1.23`版本为例。

安装完成后，执行以下命令查看版本号。

```shell
gpg --version
```

**2. 创建key**

安装完成后，执行以下命令创建key。

`GnuPG-2.x`可使用：

```shell
gpg --full-gen-key
```

`GnuPG-1.x`可使用：

```shell
gpg --gen-key
```

根据提示完成key：

> 注意：请使用Apache mail生成GPG的Key。

```shell
gpg (GnuPG) 2.0.12; Copyright (C) 2009 Free Software Foundation, Inc.
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law.

Please select what kind of key you want:
  (1) RSA and RSA (default)
  (2) DSA and Elgamal
  (3) DSA (sign only)
  (4) RSA (sign only)
Your selection? 1
RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048) 4096
Requested keysize is 4096 bits
Please specify how long the key should be valid.
        0 = key does not expire
     <n>  = key expires in n days
     <n>w = key expires in n weeks
     <n>m = key expires in n months
     <n>y = key expires in n years
Key is valid for? (0) 
Key does not expire at all
Is this correct? (y/N) y

GnuPG needs to construct a user ID to identify your key.

Real name: ${输入用户名}
Email address: ${输入邮件地址}
Comment: ${输入注释}
You selected this USER-ID:
   "${输入的用户名} (${输入的注释}) <${输入的邮件地址}>"

Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O
You need a Passphrase to protect your secret key. # 输入密码
```

**3. 查看生成的key**

```shell
gpg --list-keys
```

执行结果：

```shell
pub   4096R/700E6065 2019-03-20
uid                  ${用户名} (${注释}) <{邮件地址}>
sub   4096R/0B7EF5B2 2019-03-20
```

其中700E6065为公钥ID。

**4. 将公钥同步到服务器**

命令如下：

```shell
gpg --keyserver hkp://pool.sks-keyservers.net --send-key 700E6065
```

`pool.sks-keyservers.net`为随意挑选的[公钥服务器](https://sks-keyservers.net/status/)，每个服务器之间是自动同步的，选任意一个即可。

## 发布Apache Maven中央仓库

**1. 设置settings.xml文件**

将以下模板添加到 `~/.m2/settings.xml`中，所有密码需要加密后再填入。
加密设置可参考[这里](http://maven.apache.org/guides/mini/guide-encryption.html)。

```xml
<settings>
  <servers>
    <server>
      <id>apache.snapshots.https</id>
      <username> <!-- APACHE LDAP 用户名 --> </username>
      <password> <!-- APACHE LDAP 加密后的密码 --> </password>
    </server>
    <server>
      <id>apache.releases.https</id>
      <username> <!-- APACHE LDAP 用户名 --> </username>
      <password> <!-- APACHE LDAP 加密后的密码 --> </password>
    </server>
  </servers>
</settings>
```

**2. 更新版本说明和示例版本**

在Github主干上更新如下文件，并提交PR到主干：

```
https://github.com/apache/shardingsphere/blob/master/RELEASE-NOTES.md
```

更新`examples`模块的pom，将版本由${CURRENT.VERSION}替换为${RELEASE.VERSION}。

**3. 创建发布分支**

假设从github下载的ShardingSphere源代码在`~/shardingsphere/`目录；假设即将发布的版本为`${RELEASE.VERSION}`。
创建`${RELEASE.VERSION}-release`分支，接下来的操作都在该分支进行。

```shell
## ${name}为源码所在分支，如：master，dev-4.x
git clone --branch ${name} https://github.com/apache/shardingsphere.git ~/shardingsphere
cd ~/shardingsphere/
git pull
git checkout -b ${RELEASE.VERSION}-release
git push origin ${RELEASE.VERSION}-release
```

**4. 发布预校验**

```shell
mvn release:prepare -Prelease -Darguments="-DskipTests" -DautoVersionSubmodules=true -DdryRun=true -Dusername=${Github用户名}
```

-Prelease: 选择release的profile，这个profile会打包所有源码、jar文件以及ShardingSphere-Proxy的可执行二进制包。

-DautoVersionSubmodules=true：作用是发布过程中版本号只需要输入一次，不必为每个子模块都输入一次。

-DdryRun=true：演练，即不产生版本号提交，不生成新的tag。

**5. 准备发布**

首先清理发布预校验本地信息。

```shell
mvn release:clean
```

```shell
mvn release:prepare -Prelease -Darguments="-DskipTests" -DautoVersionSubmodules=true -DpushChanges=false -Dusername=${Github用户名}
```

和上一步演练的命令基本相同，去掉了-DdryRun=true参数。

-DpushChanges=false：不要将修改后的版本号和tag自动提交至Github。

将本地文件检查无误后，提交至github。

```shell
git push origin ${RELEASE.VERSION}-release
git push origin --tags
```

**6. 部署发布**

```shell
mvn release:perform -Prelease -Darguments="-DskipTests" -DautoVersionSubmodules=true -Dusername=${Github用户名}
```

执行完该命令后，待发布版本会自动上传到Apache的临时筹备仓库(staging repository)。
访问https://repository.apache.org/#stagingRepositories, 使用Apache的LDAP账户登录后，就会看到上传的版本，`Repository`列的内容即为${STAGING.REPOSITORY}。
点击`Close`来告诉Nexus这个构建已经完成，只有这样该版本才是可用的。
如果电子签名等出现问题，`Close`会失败，可以通过`Activity`查看失败信息。

## 发布Apache SVN仓库

**1. 检出shardingsphere发布目录**

如无本地工作目录，则先创建本地工作目录。

```shell
mkdir -p ~/ss_svn/dev/
cd ~/ss_svn/dev/
```

创建完毕后，从Apache SVN检出shardingsphere发布目录。

```shell
svn --username=${APACHE LDAP 用户名} co https://dist.apache.org/repos/dist/dev/shardingsphere
cd ~/ss_svn/dev/shardingsphere
```

**2. 添加gpg公钥**

仅第一次部署的账号需要添加，只要`KEYS`中包含已经部署过的账户的公钥即可。

```shell
gpg -a --export ${GPG用户名} >> KEYS
```

**3. 将待发布的内容添加至SVN目录**

创建版本号目录。

```shell
mkdir -p ~/ss_svn/dev/shardingsphere/${RELEASE.VERSION}
cd ~/ss_svn/dev/shardingsphere/${RELEASE.VERSION}
```

将源码包、二进制包和ShardingSphere-Proxy可执行二进制包添加至SVN工作目录。

```shell
cp -f ~/shardingsphere/shardingsphere-distribution/shardingsphere-src-distribution/target/*.zip ~/ss_svn/dev/shardingsphere/${RELEASE.VERSION}
cp -f ~/shardingsphere/shardingsphere-distribution/shardingsphere-src-distribution/target/*.zip.asc ~/ss_svn/dev/shardingsphere/${RELEASE.VERSION}
cp -f ~/shardingsphere/shardingsphere-distribution/shardingsphere-jdbc-distribution/target/*.tar.gz ~/ss_svn/dev/shardingsphere/${RELEASE.VERSION}
cp -f ~/shardingsphere/shardingsphere-distribution/shardingsphere-jdbc-distribution/target/*.tar.gz.asc ~/ss_svn/dev/shardingsphere/${RELEASE.VERSION}
cp -f ~/shardingsphere/shardingsphere-distribution/shardingsphere-proxy-distribution/target/*.tar.gz ~/ss_svn/dev/shardingsphere/${RELEASE.VERSION}
cp -f ~/shardingsphere/shardingsphere-distribution/shardingsphere-proxy-distribution/target/*.tar.gz.asc ~/ss_svn/dev/shardingsphere/${RELEASE.VERSION}
cp -f ~/shardingsphere/shardingsphere-distribution/shardingsphere-scaling-distribution/target/*.tar.gz ~/ss_svn/dev/shardingsphere/${RELEASE.VERSION}
cp -f ~/shardingsphere/shardingsphere-distribution/shardingsphere-scaling-distribution/target/*.tar.gz.asc ~/ss_svn/dev/shardingsphere/${RELEASE.VERSION}
```

**4. 生成文件签名**

```shell
shasum -a 512 apache-shardingsphere-${RELEASE.VERSION}-src.zip > apache-shardingsphere-${RELEASE.VERSION}-src.zip.sha512
shasum -b -a 512 apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-jdbc-bin.tar.gz > apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-jdbc-bin.tar.gz.sha512
shasum -b -a 512 apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-proxy-bin.tar.gz > apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-proxy-bin.tar.gz.sha512
shasum -b -a 512 apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-scaling-bin.tar.gz > apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-scaling-bin.tar.gz.sha512
```

**5. 提交Apache SVN**

```shell
svn add *
svn --username=${APACHE LDAP 用户名} commit -m "release ${RELEASE.VERSION}"
```

## 检查发布结果

**检查sha512哈希**

```shell
shasum -c apache-shardingsphere-${RELEASE.VERSION}-src.zip.sha512
shasum -c apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-jdbc-bin.tar.gz.sha512
shasum -c apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-proxy-bin.tar.gz.sha512
shasum -c apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-scaling-bin.tar.gz.sha512
```

**检查gpg签名**

首先导入发布人公钥。从svn仓库导入KEYS到本地环境。（发布版本的人不需要再导入，帮助做验证的人需要导入，用户名填发版人的即可）

```shell
curl https://dist.apache.org/repos/dist/dev/shardingsphere/KEYS >> KEYS
gpg --import KEYS
gpg --edit-key "${发布人的gpg用户名}"
  > trust

Please decide how far you trust this user to correctly verify other users' keys
(by looking at passports, checking fingerprints from different sources, etc.)

  1 = I don't know or won't say
  2 = I do NOT trust
  3 = I trust marginally
  4 = I trust fully
  5 = I trust ultimately
  m = back to the main menu

Your decision? 5

  > save
```

然后进行gpg签名检查。

```shell
gpg --verify apache-shardingsphere-${RELEASE.VERSION}-src.zip.asc apache-shardingsphere-${RELEASE.VERSION}-src.zip
gpg --verify apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-jdbc-bin.tar.gz.asc apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-jdbc-bin.tar.gz
gpg --verify apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-proxy-bin.tar.gz.asc apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-proxy-bin.tar.gz
gpg --verify apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-scaling-bin.tar.gz.asc apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-scaling-bin.tar.gz
```

**检查发布文件内容**

**对比源码包与Github上tag的内容差异**

```
curl -Lo tag-${RELEASE.VERSION}.zip https://github.com/apache/shardingsphere/archive/${RELEASE.VERSION}.zip
unzip tag-${RELEASE.VERSION}.zip
unzip apache-shardingsphere-${RELEASE.VERSION}-src.zip
diff -r apache-shardingsphere-${RELEASE.VERSION}-src-release shardingsphere-${RELEASE.VERSION}
```

**检查源码包的文件内容**

- 检查源码包是否包含由于包含不必要文件，致使tarball过于庞大
- 存在`LICENSE`和`NOTICE`文件
- `NOTICE`文件中的年份正确
- 只存在文本文件，不存在二进制文件
- 所有文件的开头都有ASF许可证
- 能够正确编译，单元测试可以通过 (./mvnw install)
- 检查是否有多余文件或文件夹，例如空文件夹等

**检查二进制包的文件内容**

解压缩
`apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-jdbc-bin.tar.gz`，
`apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-proxy-bin.tar.gz`和
`apache-shardingsphere-${RELEASE.VERSION}-shardingsphere-scaling-bin.tar.gz`
进行如下检查:

- 存在`LICENSE`和`NOTICE`文件
- `NOTICE`文件中的年份正确
- 所有文本文件开头都有ASF许可证
- 检查第三方依赖许可证：
  - 第三方依赖的许可证兼容
  - 所有第三方依赖的许可证都在`LICENSE`文件中声名
  - 依赖许可证的完整版全部在`license`目录
  - 如果依赖的是Apache许可证并且存在`NOTICE`文件，那么这些`NOTICE`文件也需要加入到版本的`NOTICE`文件中

标题：

```
[ANNOUNCE] Apache ShardingSphere ${RELEASE.VERSION} available
```

正文：

```
Hi all,

Apache ShardingSphere Team is glad to announce the new release of Apache ShardingSphere ${RELEASE.VERSION}.

ShardingSphere is an open-source ecosystem consisted of a set of distributed database middleware solutions, including 2 independent products, ShardingSphere-JDBC & ShardingSphere-Proxy. 
They both provide functions of data sharding, distributed transaction and database governance, applicable in a variety of situations such as Java isomorphism, heterogeneous language. 
Aiming at reasonably making full use of the computation and storage capacity of the database in a distributed system, ShardingSphere defines itself as a middleware, rather than a totally new type of database. 
As the cornerstone of many enterprises, relational database still takes a huge market share. 
Therefore, at the current stage, we prefer to focus on its increment instead of a total overturn.
