Release指南

如何发布一个bRPC Release版本

brpc 发布apache release 版本流程step by step

概述：分为如下几个步骤

事前准备：包括生成签名需要的key，github拉取发布分支、打tag，修改version文件等
发布软件包：包括制作source tarball，签名，上传到制定地点并验证
投票：包括在dev@brpc邮件群里投票，以及在general@incubator.apache.org邮件群里投票
发版通告：包括更新brpc网站，发邮件，发微信公众号公告，合并发布分支到master分支

签名准备

1. 安装 GPG

在GnuPG官网下载安装包。 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-2.3.1版本（OSX）为例。

安装完成后，执行以下命令查看版本号。

gpg --version

2. 创建 key

安装完成后，执行以下命令创建key。

gpg --full-gen-key

根据提示完成创建key，注意邮箱要使用Apache邮件地址，Real Name使用姓名Pinyin、Apache ID或GitHub ID等均可：

gpg (GnuPG) 2.3.1; Copyright (C) 2021 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
   (2) DSA and Elgamal
   (3) DSA (sign only)
   (4) RSA (sign only)
   (9) ECC (sign and encrypt) *default*
  (10) ECC (sign only)
  (14) Existing key from card
Your selection? 1
RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (3072) 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) 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: LorinLee
Email address: lorinlee@apache.org
Comment: lorinlee's key
You selected this USER-ID:
    "LorinLee (lorinlee's key) <lorinlee@apache.org>"

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

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.
gpg: key 92E18A11B6585834 marked as ultimately trusted
gpg: revocation certificate stored as '/Users/lilei/.gnupg/openpgp-revocs.d/C30F211F071894258497F46392E18A11B6585834.rev'
public and secret key created and signed.

pub   rsa4096 2021-10-17 [SC]
      C30F211F071894258497F46392E18A11B6585834
uid                      LorinLee (lorinlee's key) <lorinlee@apache.org>
sub   rsa4096 2021-10-17 [E]

3. 查看生成的key

gpg --list-keys

执行结果：

gpg: checking the trustdb
gpg: marginals needed: 3  completes needed: 1  trust model: pgp
gpg: depth: 0  valid:   2  signed:   0  trust: 0-, 0q, 0n, 0m, 0f, 2u
/Users/lilei/.gnupg/pubring.kbx
----------------------------------
pub   rsa4096 2021-10-17 [SC]
      C30F211F071894258497F46392E18A11B6585834
uid           [ultimate] LorinLee (lorinlee's key) <lorinlee@apache.org>
sub   rsa4096 2021-10-17 [E]

其中 C30F211F071894258497F46392E18A11B6585834 为公钥ID。

4. 将公钥公布到服务器

命令如下：

gpg --keyserver hkp://pgp.mit.edu --send-key C30F211F071894258497F46392E18A11B6585834

5. 生成 fingerprint 并上传到 apache 用户信息中

由于公钥服务器没有检查机制，任何人都可以用你的名义上传公钥，所以没有办法保证服务器上的公钥的可靠性。通常，你可以在⽹站上公布一个公钥指纹，让其他⼈核对下载到的公钥是否为真。fingerprint参数生成公钥指纹。

执行如下命令查看 fingerprint：

gpg --fingerprint lorinlee（用户ID）

输出如下：

/Users/lilei/.gnupg/pubring.kbx
----------------------------------
pub   rsa4096 2021-10-17 [SC]
      C30F 211F 0718 9425 8497  F463 92E1 8A11 B658 5834
uid           [ultimate] LorinLee (lorinlee's key) <lorinlee@apache.org>
sub   rsa4096 2021-10-17 [E]

将上面的 fingerprint C30F 211F 0718 9425 8497 F463 92E1 8A11 B658 5834 粘贴到⾃己Apache⽤户信息 https://id.apache.org 的OpenPGP Public Key Primary Fingerprint:字段中。

发布包准备

1. 拉出发版分支

如果是发布新的2位版本，如1.0.0，则需要从master拉出新的分支release-1.0。

如果是在已有的2位版本上发布新的3位版本，如1.0.1版本，则只需要在已有的release-1.0分支上修改加上要发布的内容。

发版过程中的操作都在release分支（如release-1.0）上操作，如果发版过程发现代码有问题需要修改，也在该分支上进行修改。发版完成后，将该分支合回master分支。

2. 编辑 RELEASE_VERSION 文件

更新RELEASE_VERSION文件

编辑项目根目录下RELEASE_VERSION文件，更新版本号，并提交至代码仓库，本文以1.0.0版本为例，文件内容为：

1.0.0

更新CMakeLists.txt文件

编辑项目根目录下CMakeLists.txt文件，更新版本号，并提交至代码仓库，本文以1.0.0版本为例，修改BRPC_VERSION为：

set(BRPC_VERSION 1.0.0)

更新/package/rpm/brpc.spec文件

编辑项目根目录下/package/rpm/brpc.spec文件，更新版本号，并提交至代码仓库，本文以1.0.0版本为例，修改Version为：

Version:	1.0.0

3. 创建发布 tag

拉取发布分支，并推送tag

git clone -b release-1.0 git@github.com:apache/brpc.git ~/brpc

cd ~/brpc

git tag -a 1.0.0 -m "release 1.0.0"

git push origin --tags

4. 打包发布包

git archive --format=tar 1.0.0 --prefix=apache-brpc-1.0.0-incubating-src/ | gzip > apache-brpc-1.0.0-incubating-src.tar.gz

5. 生成签名文件

gpg -u lorinlee@apache.org --armor --output apache-brpc-1.0.0-incubating-src.tar.gz.asc --detach-sign apache-brpc-1.0.0-incubating-src.tar.gz

gpg --verify apache-brpc-1.0.0-incubating-src.tar.gz.asc apache-brpc-1.0.0-incubating-src.tar.gz

6. 生成哈希文件

sha512sum apache-brpc-1.0.0-incubating-src.tar.gz > apache-brpc-1.0.0-incubating-src.tar.gz.sha512

sha512sum --check apache-brpc-1.0.0-incubating-src.tar.gz.sha512

发布至Apache SVN仓库

1. 检出 dist/dev 下的 brpc 仓库目录

如无本地工作目录，则先创建本地工作目录。将Apache SVN仓库克隆下来，username需要使用自己的Apache LDAP用户名

mkdir -p ~/brpc_svn/dev/

cd ~/brpc_svn/dev/

svn --username=lorinlee co https://dist.apache.org/repos/dist/dev/brpc/

cd ~/brpc_svn/dev/brpc

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。

(gpg --list-sigs lorinlee && gpg -a --export lorinlee) >> KEYS

3. 将待发布的代码包添加至SVN目录

mkdir -p ~/brpc_svn/dev/brpc/1.0.0

cd ~/brpc_svn/dev/brpc/1.0.0

cp ~/brpc/apache-brpc-1.0.0-incubating-src.tar.gz ~/brpc_svn/dev/brpc/1.0.0

cp ~/brpc/apache-brpc-1.0.0-incubating-src.tar.gz.asc ~/brpc_svn/dev/brpc/1.0.0

cp ~/brpc/apache-brpc-1.0.0-incubating-src.tar.gz.sha512 ~/brpc_svn/dev/brpc/1.0.0

4. 提交SVN

退回到上级目录，使用Apache LDAP账号提交SVN

cd ~/brpc_svn/dev/brpc

svn add *

svn --username=lorinlee commit -m "release 1.0.0"

检查发布结果

1. 检查sha512哈希

sha512sum --check apache-brpc-1.0.0-incubating-src.tar.gz.sha512

2. 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）

curl https://dist.apache.org/repos/dist/dev/brpc/KEYS >> KEYS

gpg --import KEYS

设置信任该用户的签名，执行以下命令，填写发布人的用户名

gpg --edit-key lorinlee

输出为

gpg (GnuPG) 2.3.1; Copyright (C) 2021 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.

Secret key is available.

gpg> 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
Do you really want to set this key to ultimate trust? (y/N) y

gpg> save

然后进行gpg签名检查。

gpg --verify apache-brpc-1.0.0-incubating-src.tar.gz.asc apache-brpc-1.0.0-incubating-src.tar.gz

3. 检查发布内容

1. 对比源码包与github上的tag内容差异

curl -Lo tag-1.0.0.tar.gz https://github.com/apache/brpc/archive/refs/tags/1.0.0.tar.gz

tar xvzf tag-1.0.0.tar.gz

tar xvzf apache-brpc-1.0.0-incubating-src.tar.gz

diff -r brpc-1.0.0 apache-brpc-1.0.0-incubating-src

2. 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
检查是否有多余文件或文件夹，例如空文件夹等
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
