+# Apache 软件发版流程
+
+> author: wongoo@apache.org
+> last updated: 2020-03-06
+
+Apache开源软件是有社区驱动的,为了提高发布软件质量而指定了软件发布流程,本文主要介绍此流程,以给第一次发布打包的apacher参考。
+
+如果你要准备打包一个apache软件了,想必你已经是一个项目的committer了,而且知道社区、PMC这些概念,而你现在还担任本次发布的 release manager 一职。
+
+发版流程其实也很简单,无非如下:
+1. 整理变更内容,打包并对打包文件签名;
+2. 将签名文件上传apache svn仓库;
+3. 发邮件请社区PMC大佬投票;
+4. 投票通过后发一个投票结果通告邮件;
+5. 发版
+6. 发版邮件通告社区新版本发布;
+
+下面详细整理发版的一些流程步骤,使用 dubbo 的子项目 dubbog-go-hessian2 发版为例!
+
+
+## 1. 发版准备
+
+发版文件需要签名,需要安装pgp工具. 
+
+```bash
+$ brew install gpg
+$ gpg --version
+$ gpg --full-gen-key
+	(1) RSA and RSA (default)  <-- RSA 类型
+	What keysize do you want? (2048) 4096  <-- key大小为4096
+	0 = key does not expire    <-- 永不过期
+	Real name: Liu Yang
+	Email address: wongoo@apache.org
+	Comment: CODE SIGNING KEY

+	sub   rsa4096 2019-10-17 [E]
+
+
+# 公钥服务器是网络上专门储存用户公钥的服务器
+# 通过key id发送public key到keyserver
+$ gpg --keyserver pgpkeys.mit.edu --send-key 1376A2FF67E4C477573909BD7DB68550D366E4C0
+	gpg: sending key 7DB68550D366E4C0 to hkp://pgpkeys.mit.edu
+# 其中,pgpkeys.mit.edu为随意挑选的keyserver,keyserver列表为:https://sks-keyservers.net/status/,为相互之间是自动同步的,选任意一个都可以。
+
+# 如果有多个public key,设置默认key。修改 ~/.gnupg/gpg.conf
+$ vi ~/.gnupg/gpg.conf
+default-key 7DB68550D366E4C0
+
+# 如果有多个public key, 也可以删除无用的key:
+### 先删除私钥,再删除公钥
+$ gpg --yes --delete-secret-keys shenglicao2@gmail.com   ###老的私钥,指明邮箱即可
+$ gpg --delete-keys 1808C6444C781C0AEA0AAD4C4D6A8007D20DB8A4
+
+## 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:
+$ gpg --fingerprint wongoo

+```
+
+> 详细参考:
+> - 发布签名: http://www.apache.org/dev/release-signing.html
+> - 发布策略: http://www.apache.org/dev/release-distribution
+> - 将密钥上传到公共密钥服务器: https://www.apache.org/dev/openpgp.html#generate-key
+
+## 2. 打包签名
+
+准备打包前(尤其提第一次打包)需要注意以下内容:
+- 每个文件的LICENSE头部是否正确, 包括 `*.java`, `*.go`, `*.xml`, `Makefile` 等
+- LICENSE 文件是否存在
+- NOTICE 文件是否存在
+- CHANGE.md 是否存在 (变更内容格式符合规范)
+
+以上可以参考其他已发布项目的配置。
+
+
+```
+

+## 4. 发投票 [VOTE] 邮件
+
+发任何邮件都是有一定格式的,你加入社区邮件列表后,就会收到很多这样的邮件,多看看就知道了,具体邮件范本参考文章后面的邮件范本。
+
+发完【VOTE】邮件,私下沟通群里面请大佬PMC投票。
+PMC投票会对你上传打包文件进行相关检查, 
+详细可以了解孵化中的项目发布完整的检查项参考: https://cwiki.apache.org/confluence/display/INCUBATOR2/IncubatorReleaseChecklist
+
+收到3个binding邮件且超过72小时后,就可以发 投票结果 [RESULT] [VOTE] 邮件了。
+
+> 原则上只有PMC的投票才算binding邮件, 当然也可以由社区决定。
+
+这一步骤最常见有以下问题:
+- 文件签名有问题
+- 引用项目LICENSE问题
+- 单元测试不通过
+
+> 另外需要注意: 一个apache项目可能包含很多子项目,项目的PMC可能只对主项目比较了解,	他们并不清楚如何将子项目跑起来,也不知道如何跑单元测试,最好在邮件中附带一个如何进行单元测试的连接。例如 PMC 最了解 java,但子项目是golang,python,js等,你需要告诉他们如何测试你的项目。
+
+可以参考投票规则: https://www.apache.org/foundation/voting.html
+
+## 5. 发布版本
+
+当正式发布投票成功后,先发[Result]邮件,然后就准备 release package。 
+将之前在dev下发布的对应rc文件夹下的源码包、签名文件和hash文件拷贝到另一个目录 v1.4.0,
+注意文件名字中不要rcxx (可以rename,但不要重新计算签名,hash可以重新计算,结果不会变)。
+
+将release包移动到正式版目录。如果你的软件是需要客户从apache下载的,则这一步是必须的。如果不是,比如golang引用github打包地址的则可以忽略。
+```
+svn up
+cd dubbo-go-hessian2
+svn move v1.4.0-rc1 v1.4.0
+svn status
+svn commit  --username wongoo -m "Release dubbo-go-hessian2 v1.4.0"
+```
+
+移到发版目录后,还需要进行相应的正式版本发布, 这里将具体发布方式整理到单独的章节 `7. 不同语言版本发布`,因为发布流程马上就要结束了 ^v^

+Great improvement over the previous release but there are still issues from the last vote that have not been resolved. e.g. [6][7][8]

+
+Can people please carefully check the contents, and write down what you checked, rather than just saying +1.
+
+I checked:
+- signatures and hashes good
+- LICENSE is missing the appendix (not a major issue)
+- LICENSE may be is missing some information[1][2][3][4][5]
+- NOTICE is fine
+- No binaries in source release
+- Some files are missing ASF headers or other license headers [1][2][3][4][5] - please fix
