-<h3>The active contributor is elected as a committer</h3>
-<p>At the late development stage, an active contributor can be elected as a 
committer. See <a 
href="https://www.apache.org/dev/new-committers-guide.html#becoming-a-committer";>how
 to become a committer</a></p>
-<h2>Second: The individual contributor signs ICLA</h2>
-<h3>1, Apache ID</h3>
-<p>Choose a Apache ID not in the <a 
href="http://people.apache.org/committer-index.html";>apache committers list 
page</a>.</p>
-<h3>2, Individual Contributor License Agreement  (ICLA):</h3>
-<p>Download the <a href="https://www.apache.org/licenses/icla.pdf";>ICLA 
template</a>. After filling the icla.pdf with personal information correctly, 
print, sign, scan, and send it in mail as an attachment to the secretary <a 
href="mailto:secret...@apache.org";>secret...@apache.org</a>, the secretary will 
help to create the Apache user ID. At the same time, a <a 
href="mailto:your...@apache.org";>your...@apache.org</a> mailbox will be 
created. You can see if the user has been created on the [...]
-<h2>Third: Join The Apache Developer Group</h2>
-<ul>
-<li>
-<p>1, login via the <a href="https://id.apache.org/";>Apache account tool</a>, 
when you login at the first time, you can select the &quot;Change 
password?&quot; checkbox  to get the initial password. Then the initial 
password will be sent to the forward mailbox (the developer mail recorded in 
the project incubator proposal)</p>
-</li>
-<li>
-<p>2, about Apache mailbox: does not have its own mail content storage server. 
It needs to borrow the mail content storage and mail sending functions of other 
mail providers. In many voting sessions, Apache mailbox is recommended.</p>
-</li>
-</ul>
-<p>There is a question about how to configure the <a 
href="http://apache.org";>apache.org</a> mailbox forwarding function using other 
mailboxes.</p>
-<ol>
-<li>
-<p>inbox: to receive mails that sent to <a 
href="mailto:youer...@apache.org";>youer...@apache.org</a> mailbox. The forward 
mailbox configured in the Apache account tool in the first step can use the 
forward mailbox to pick up incoming mail.</p>
-</li>
-<li>
-<p>the Outbox: emails sent out will show the sender as  <a 
href="mailto:your...@apache.org";>your...@apache.org</a> account. Please refer 
to: <a href="https://reference.apache.org/committer/email";>set up Apache 
mailbox guide</a> and <a 
href="http://gmailblog.blogspot.com/2009/07/send-mail-from-another-address-without.html";>Gmail
 mailbox setting</a>. In other mailbox service settings, this forwarding mode 
is not easy to find. Gmail is the most convenient, which is recommended  (no 
advertis [...]
-</li>
-</ol>
-<ul>
-<li>
-<p>3, Modify the homepage URL option in the edit page, homepage link of  your 
account can be added in <a 
href="http://people.apache.org/committer-index.html";>apache committer index 
page</a></p>
-</li>
-<li>
-<p>4, Modify the GitHub account in the edit page, and an email will be sent to 
invite you to join the <a 
href="http://github.com/apache-commiiters";>github.com/apache-commiiters</a> 
group. Now, please learn from the way <a 
href="http://www.apache.org/foundation/how-it-works.html#developers";>ASF 
works</a> to do some basic preparation of ASF development.</p>
-</li>
-</ul>
-<h2>Fourth: To obtain write permission of the project</h2>
-<p>Operation of the <a href="https://gitbox.apache.org/setup/";>GitBox account 
link tool</a></p>
-<h3>1, Apache account authorization</h3>
-<p>According to the prompt, the OAuth protocol of Apache account is authorized 
to login.</p>
-<h3>2, Github account authorization</h3>
-<p>According to the prompt, the OAuth protocol of Github account is authorized 
to login.</p>
-<h3>3, Set up GitHub account in <a href="http://github.com";>github.com</a>, 
two-factors authorization (2FA)</h3>
-<ul>
-<li>
-<ol>
-<li>install &quot;Google Authenticator&quot; app on your cell phone</li>
-</ol>
-</li>
-<li>2), Following the <a 
href="https://help.github.com/articles/configuring-two-factor-authentication-via-a-totp-mobile-app/";>authorized
 GitHub 2FA wiki</a>,  you can operation step by step .</li>
-</ul>
-<p>In the <a 
href="https://github.com/settings/two_factor_authentication/verify";>two-factors 
authorization authentication (2. Scan this barcode with your app.)</a> page, it 
is not recommended to select a two-dimensional code with a cell phone, because 
some of the cell phones will not be able to scan.</p>
-<p>Please open the cell phone &quot;Google Authenticator&quot; app, click 
&quot;+&quot; to select &quot;input the secret key&quot;: write the GitHub 
account in the account name input box. In your &quot;secret key&quot; input 
box, write the text of the &quot;enter this text code&quot; link in the open 
web page. After clicking &quot;add&quot; in app, 6 digit dynamic will be 
generated for this account. Write the 6 digit number to the text box in the web 
page, and then click &quot;Enable&quo [...]
-<ul>
-<li>
-<p>3), logout and login to Github again, and one more step will appear after 
entering user name and password. Fill in the 6 digit number dynamic password  
generated by the app</p>
-</li>
-<li>
-<p>4),It will take about half an hour, and you will be notified by mail that 
you have joined the XX project-committers developer group. You can also check 
it in the [apache teams] (<a 
href="https://github.com/orgs/apache/teams";>https://github.com/orgs/apache/teams</a>)
 page yourself.</p>
-</li>
-<li>
-<p>5), After the 2fa has been submitted, you will have the permission check 
problem for the cloned projects. The solution is one of below two:</p>
-</li>
-<li>
-<p>A. Apply for Access Token</p>
-</li>
-</ul>
-<p>When access token is generated on GitHub, the token where the instruction 
line needs a password is pasted.</p>
-<p>Refer to website <a 
href="https://help.github.com/articles/https-cloning-errors/#provide-access-token-if-2fa-enabled";>referenced
 link one</a> and <a 
href="https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/";>referenced
 link two</a></p>
-<ul>
-<li>B. switch to SSH</li>
-</ul>
-<p>ssh-keygen then paste the content in the pub file into GitHub.</p>
-<p><strong>Note</strong>: ensure that GitHub's 2fa is &quot;enabled&quot;. 
When you set 2fa to &quot;off&quot;, it will be delisted by the corresponding 
Apache committer write permission group until you set it up again.</p>
-<h2>Fifth: other</h2>
-<h3>The Apache way</h3>
-<p>See <a href="http://apache.org/foundation/governance/";>wiki</a>.</p>
-<p>The community is more important than the code
-If not discussed in the community (mailing list), just as it did not happen</p>
-<h3>A small benefit</h3>
-<p>Jetbrains company gives Apache committers a small benefit, which is free to 
use IDEA's full series products. The specific address is: <a

-<p>Dubbo Use microkernel + plugin design pattern. Microkernel is only 
responsible for assembling plugins, the functions of Dubbo are implemented by 
extension points(plugins), which means that all functions of Dubbo can be 
replaced by user customized extension.</p>
-<h2>Dubbo Ecosystem</h2>
-<p>We recommend you to put extension to Dubbo <a 
href="https://github.com/dubbo";>ecosystem</a>. Using this pattern will keep the 
core repository cleaner and decrease the maintains work. With less code also 
speed up core repository build process.</p>
-<h2>Dependency</h2>
-<p>Implement your own Dubbo extension, in general is just dependence on API 
jar correspond to what you want.
-For example:</p>
-<pre><code class="language-xml"><span class="hljs-tag">&lt;<span 
class="hljs-name">dependency</span>&gt;</span>
-    <span class="hljs-tag">&lt;<span 
class="hljs-name">groupId</span>&gt;</span>org.apache.dubbo<span 
class="hljs-tag">&lt;/<span class="hljs-name">groupId</span>&gt;</span>
-    <span class="hljs-tag">&lt;<span 
class="hljs-name">artifactId</span>&gt;</span>dubbo-serialization-api<span 
class="hljs-tag">&lt;/<span class="hljs-name">artifactId</span>&gt;</span>
-    <span class="hljs-tag">&lt;<span 
class="hljs-name">version</span>&gt;</span>${dubbo.version}<span 
class="hljs-tag">&lt;/<span class="hljs-name">version</span>&gt;</span>
-<span class="hljs-tag">&lt;/<span 
class="hljs-name">dependency</span>&gt;</span>
-</code></pre>
-<h2>Src Guide</h2>
-<p>Usually, implement special extension, just need reference the <a 
href="http://dubbo.apache.org/#/docs/dev/build.md?lang=en-us";>Developer 
Guide</a> docs. Implement necessary interface and adapt extension to dubbo. 
Besides, some others should be considered:</p>
-<ol>
-<li>Well tested. You should write unit test and mock test to eliminate 
potential bugs.</li>
-<li>No warning, if some warning cannot to avoid, use @SuppressWarnings to 
suppress it, but do not abuse it.</li>
-<li>README. Add necessary readme to show how to use your extension, and 
something to take notice.</li>
-<li>License. Make sure of use Apache License 2.0.</li>
-</ol>
-<h2>Notify the Community</h2>
-<ol>
-<li>Commit your code to <a href="https://github.com";>GitHub</a>.</li>
-<li>Join the mail list (recommended). <a 
href="https://github.com/apache/incubator-dubbo/wiki/Mailing-list-subscription-guide";>HowTo</a></li>
-<li>Send email to <a 
href="mailto:d...@incubator.dubbo.apache.org";>d...@incubator.dubbo.apache.org</a>
 to notify the community</li>
-<li>Usually, after sending email, community will discuss your extension, and 
Administrators of dubbo group will contact you for transfer project to dubbo 
ecosystem.</li>
-</ol>
-<h2>Transfer Project to Dubbo Group</h2>
-<ol>

-<h3>1.The benefits of unit testing</h3>
-<ul>
-<li>Unit test code can help everyone to go into details and understand the 
function of the code.</li>
-<li>We can find bugs by test case, and then enhance the robustness of the 
code.</li>
-<li>Test case code is also the demo usage of the core code.</li>
-</ul>
-<h3>2.Some design principle of unit test case</h3>
-<ul>
-<li>Steps, fine-grained and combination conditions should be well 
designed.</li>
-<li>Attention to boundary condition test</li>
-<li>Test code should also be designed without writing useless code.</li>
-<li>When you find a <code>method</code> that is hard to write unit test, if 
you can be sure the <code>method</code> is &quot;smelly code&quot;, then  
refactor it with the committer.</li>
-<li>The mock framework in dubbo is: <a 
href="http://site.mockito.org/";>mockito</a>. Some tutorials:<a 
href="http://www.baeldung.com/bdd-mockito";>mockito tutorial</a>,<a 
href="https://dzone.com/refcardz/mockito";>mockito refcard</a></li>
-<li>TDD(optional):When you start a new issue, you can try to write test case 
at first</li>
-</ul>
-<h3>3.The specified value of the test coverage</h3>
-<ul>
-<li>In the stage, the test coverage specified value of delta changed codes is 
:&gt;=60%. The higher, the better.</li>
-<li>We can see the coverage report in this page: <a

-<h3>Where is dubbo-admin?</h3>
-<p>dubbo-admin has been moved from core repository to <a 
href="https://github.com/apache/incubator-dubbo-ops";>https://github.com/apache/incubator-dubbo-ops</a>
 since 2.6.1</p>
-<h3>Which version should I choose?</h3>
-<p>Currently, dubbo keeps 3 versions evolve in parallel:</p>
-<ul>
-<li>
-<p>2.7.x (master): requires Java 1.8, major feature branch.</p>
-</li>
-<li>
-<p>2.6.x: requires Java 1.6, minor feature &amp; bugfix branch, GA, production 
ready.</p>
-</li>
-<li>
-<p>2.5.x: requires Java 1.6, maintenance branch, only accept security 
vulnerability and critical bugfix, expected to be EOL soon.</p>
-</li>
-</ul>
-<p>check <a 
href="https://github.com/apache/incubator-dubbo/issues/1208";>this</a> for 
detailed version management plan.</p>
-<p>For contributors, please make sure all changes on the right branch, that 
is, most of the pull request should go to 2.7.x, and be backported to 2.6.x and 
2.5.x if necessary. If the fix is specific to a branch, please make sure your 
pull request goes to the right branch.</p>
-<p>For committers, make sure select the right label and target branch for 
every PR, and don't forget to back port the fix to lower version is 
necessary.</p>

 since 2.6.1</p>
-<h3>Which version should I choose?</h3>
-<p>Currently, dubbo keeps 3 versions evolve in parallel:</p>
-<ul>
-<li>
-<p>2.7.x (master): requires Java 1.8, major feature branch.</p>
-</li>
-<li>
-<p>2.6.x: requires Java 1.6, minor feature &amp; bugfix branch, GA, production 
ready.</p>
-</li>
-<li>
-<p>2.5.x: requires Java 1.6, maintenance branch, only accept security 
vulnerability and critical bugfix, expected to be EOL soon.</p>
-</li>
-</ul>
-<p>check <a 
href="https://github.com/apache/incubator-dubbo/issues/1208";>this</a> for 
detailed version management plan.</p>
-<p>For contributors, please make sure all changes on the right branch, that 
is, most of the pull request should go to 2.7.x, and be backported to 2.6.x and 
2.5.x if necessary. If the fix is specific to a branch, please make sure your 
pull request goes to the right branch.</p>
-<p>For committers, make sure select the right label and target branch for 
every PR, and don't forget to back port the fix to lower version is 
necessary.</p>

-<h2>一、apache提交者的产生</h2>
-<h3>项目孵化初始化提交者</h3>
-<p>项目孵化阶段,在孵化项目提案中,会有初始化提交者列表这一选项。确认你是初始化提交者的一员。项目在apache孵化器社区投票通过后,提交者可以开始准备注册账户了。可以参看<a
 href="https://wiki.apache.org/incubator/";>孵化器wiki</a></p>
-<h3>活跃的贡献者被选举为提交者</h3>
-<p>在后期的开发过程中,活跃的贡献者可以被选举为提交者。见<a 
href="https://www.apache.org/dev/new-committers-guide.html#becoming-a-committer";>如何成为committer</a></p>
-<h2>二、个人开发者提交ICLA</h2>
-<h3>1、选apache id</h3>
-<p>在<a 
href="http://people.apache.org/committer-index.html";>apache提交者列表页</a>查看可用的apache
 id,</p>
-<h3>2、个人提交者授权协议(ICLA):</h3>
-<p>下载<a 
href="https://www.apache.org/licenses/icla.pdf";>ICLA模板</a>,查找可用的id。将icla.pdf个人信息填写正确后打印,签名、扫描、并当做附件发送邮件给秘书
 <a href="mailto:secret...@apache.org";>secret...@apache.org</a>,秘书会帮忙创建apache 
用户id。同时会创建一个your i...@apache.org的邮箱,可以在<a 
href="http://people.apache.org/committer-index.html";>apache提交者列表页</a>查看查找用户是否已经创建。</p>
-<h3>3、导师帮助提交用户id创建请求</h3>
-<p>导师将帮助提交apache账户创建请求给root邮件组,会有人帮助建立id。一般需要2天时间账户会建立,请等待并在<a 
href="http://people.apache.org/committer-index.html";>apache提交者列表页</a>查看查找用户是否已经创建。</p>
-<h2>三、加入apache开发者组</h2>
-<ul>
-<li>1、登入<a 
href="https://id.apache.org/";>Apache账户工具</a>,首次登入可以选忘记密码获得初始化密码,会发送到forward邮箱(在孵化项目提案中提交的开发者邮件)</li>
-<li>2、关于apache邮箱:apache.org邮箱并没有自己的邮件内容存储服务器。他是需要借用其他邮件提供商的邮件内容存储、分发功能。在很多投票环节是建议用apache邮箱的。
-这就就有一个问题,怎么在其他邮箱里面配置好apache.org邮箱转发功能:
-1)收件箱:收取发送到apache.org的邮件。这个在第一步配置好Apache账户工具的forward邮箱就可以用forward邮箱收取邮件了
-2)发件箱:将发出的邮件显示发件邮箱为apache.org邮箱。请参考:<a 
href="https://reference.apache.org/committer/email";>设置apache邮箱指南</a>和<a 
href="http://gmailblog.blogspot.com/2009/07/send-mail-from-another-address-without.html";>gmail邮箱设置方式</a>。
 其他邮箱服务的设置方式不方便找到,gmail的最方便,建议换成gmail邮箱(不是广告)。</li>
-<li>3、修改编辑页面的homepage url,<a 
href="http://people.apache.org/committer-index.html";>apache提交者列表页</a>中你的账户能加主页链接。</li>
-<li>4、修改编辑页面的github账户,<a 
href="http://xn--github-h18irjwvs5n80dryepv0gwb7ftho8ua.com/apache-commiiters%E7%BB%84%E3%80%82%E8%BF%99%E6%97%B6%E9%97%B4%E8%AF%B7%E7%9C%8B";>会发有邮件邀请你加入github.com/apache-commiiters组。这时间请看</a><a
 
href="http://www.apache.org/foundation/how-it-works.html#developers";>ASF工作方式</a>对ASF开发做一些基本了解。</li>
-</ul>
-<h2>四、提交者获得对项目的写权限</h2>
-<p><a href="https://gitbox.apache.org/setup/";>GitBox账户链接工具</a>的操作</p>
-<h3>1、Apache账户授权</h3>
-<p>按照提示授权对Apache账户的OAuth协议登入</p>
-<h3>2、Github账户授权</h3>
-<p>按照提示授权对Github账户的OAuth协议登入</p>
-<h3>3、在github.com设置github账户两因素授权(2FA)</h3>
-<p>按照<a 
href="https://help.github.com/articles/configuring-two-factor-authentication-via-a-totp-mobile-app/";>授权GitHub
 2FA wiki</a>操作如下:</p>
-<ul>
-<li>
-<p>1)、在手机安装 “google身份验证器” app</p>
-</li>
-<li>
-<p>2)、按照<a 
href="https://help.github.com/articles/configuring-two-factor-authentication-via-a-totp-mobile-app/";>授权GitHub
 2FA wiki</a>一步一步操作。</p>
-<p>在<a 
href="https://github.com/settings/two_factor_authentication/verify";>两因素授权验证(2. 
Scan this barcode with your app.)</a>界面,不建议选择用手机扫描二维码,因为有些手机会扫描不出来。
-请打开手机 “google身份验证器” app,点“+”选择“输入提供的秘钥”: 
在“账户名”input框写入github账户。在“您的秘钥”input框写入:打开的网页中&quot;enter this text code&quot; 
链接里面的文本。在app中点击&quot;添加&quot; 
后,将为此账户生成6位数字动态。将此6位数字写入网页中的文本框,然后点“Enable”。这样2fa就设置成功了。</p>
-</li>
-<li>
-<p>3)、退出并重新登入Github,输入用户名、密码后会多一步。动态密码的填写,用app的动态密码</p>
-</li>
-<li>
-<p>4)、约需要半个小时,会有邮件通知你已经加入了xx project-committers开发者组。你也可以自己去<a 
href="https://github.com/orgs/apache/teams";>apache teams</a> 页面查看。</p>
-</li>
-<li>
-<p>5)、2fa提交后你已经clone的项目会有权限校验问题,解决方法为下面二选一:</p>
-<ul>
-<li>a.申请Access Token
-在github上 生成access token 后,指令行需要密码的地方就粘贴token。
-参考官网<a 
href="https://help.github.com/articles/https-cloning-errors/#provide-access-token-if-2fa-enabled";>帮助链接一</a>和<a
 
href="https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/";>帮助链接二</a></li>
-<li>b. 改用ssh
-ssh-keygen 然后把pub文件中的内容粘贴到github上</li>
-</ul>
-</li>
-<li>
-<p>注意:一定要保证github的2fa为&quot;enable&quot;状态。当你将2fa设置为&quot;off&quot;时候,将会被对应的apache
 committer写权限组除名,直到你再次设置成功为止。</p>
-</li>
-</ul>
-<h2>五、其他</h2>
-<h3>The apache way</h3>
-<p>参看<a href="http://apache.org/foundation/governance/";>wiki</a></p>
-<p>社区重于代码
-如果没有在社区(邮件列表)讨论过,就当没有发生过</p>
-<h3>小福利</h3>
-<p>Jetbrains给apache提交者一个小福利,就是可以免费使用idea的全产品系列。具体注册地址为:<a 
href="https://www.jetbrains.com/shop/eform/apache?product=ALL";>https://www.jetbrains.com/shop/eform/apache?product=ALL</a></p>

-<h3>1.写单元测试的收益</h3>
-<ul>
-<li>单元测试能帮助每个人深入代码细节,了解代码的功能。</li>
-<li>通过测试用例我们能发现bug,并提交代码的健壮性。</li>
-<li>测试用例同时也是代码的demo用法。</li>
-</ul>
-<h3>2.单元测试用例的一些设计原则</h3>
-<ul>
-<li>应该精心设计好步骤,颗粒度和组合条件。</li>
-<li>注意边界条件。</li>
-<li>单元测试也应该好好设计,不要写无用的代码。</li>
-<li>当你发现一个<code>方法</code>很难写单元测试时,如果可以确认这个<code>方法</code>是<code>臭代码</code>,那么就和开发者一起重构它。</li>
-<li>Dubbo中用的mock框架是: <a href="http://site.mockito.org/";>mockito</a>. 
下面是一些开发向导:<a href="http://www.baeldung.com/bdd-mockito";>mockito tutorial</a>,<a 
href="https://dzone.com/refcardz/mockito";>mockito refcard</a></li>
-<li>TDD(optional):When you start a new issue, you can try to write test case 
at first</li>

-<h3>3.测试覆盖率设定值</h3>
-<ul>
-<li>在现阶段,Delta更改代码的测试覆盖设定值为:&gt;=60%,越高越好。</li>
