<p>所有的 feature 和 bug fix 的开发工作都应该在一个新的分支上完成，一般从 <code class="docutils literal"><span class="pre">develop</span></code> 分支上创建新分支。</p>
<p>使用 <code class="docutils literal"><span class="pre">git</span> <span class="pre">checkout</span> <span class="pre">-b</span></code> 创建并切换到新分支。</p>
<div class="highlight-bash"><div class="highlight"><pre><span></span>➜  git checkout -b my-cool-stuff

</div>
<p>值得注意的是，在 checkout 之前，需要保持当前分支目录 clean，否则会把 untracked 的文件也带到新分支上，这可以通过 <code class="docutils literal"><span class="pre">git</span> <span class="pre">status</span></code> 查看。</p>

<p>Paddle 开发人员使用 <a class="reference external" href="http://pre-commit.com/">pre-commit</a> 工具来管理 Git 预提交钩子。 它可以帮助我们格式化源代码（C++，Python），在提交（commit）前自动检查一些基本事宜（如每个文件只有一个 EOL，Git 中不要添加大文件等）。</p>
<p><code class="docutils literal"><span class="pre">pre-commit</span></code>测试是 Travis-CI 中单元测试的一部分，不满足钩子的 PR 不能被提交到 Paddle，首先安装并在当前目录运行它：</p>
<div class="highlight-bash"><div class="highlight"><pre><span></span>➜  pip install pre-commit
➜  pre-commit install
</pre></div>
</div>
<p>Paddle 使用 <code class="docutils literal"><span class="pre">clang-format</span></code> 来调整 C/C++ 源代码格式，请确保 <code class="docutils literal"><span class="pre">clang-format</span></code> 版本在 3.8 以上。</p>

<div class="section" id="">
<span id="id5"></span><h2>构建和测试<a class="headerlink" href="#" title="永久链接至标题">¶</a></h2>
<p>编译 PaddlePaddle 的源码以及生成文档需要多种开发工具。为了方便大家，我们的标准开发流程是把这些工具都装进一个Docker image，称为<em>开发镜像</em>，通常名字是 <code class="docutils literal"><span class="pre">paddle:dev</span></code>。然后所有用 <code class="docutils literal"><span class="pre">cmake</span> <span class="pre">&amp;&amp;</span> <span class="pre">make</span></code> 的地方（比如IDE配置里）都用 <code class="docutils literal"><span class="pre">docker</span> <span class="pre">run</span> <span class="pre">paddle:dev</span></code>来代替。</p>
<p>如要build这个开发镜像，在源码目录树的根目录中运行：</p>
<div class="highlight-bash"><div class="highlight"><pre><span></span>➜  docker build -t paddle:dev .
</pre></div>
</div>
<p>随后可以用这个开发镜像开始build PaddlePaddle的源码。比如如果要build一个不依赖GPU，但是支持AVX指令集，并且包括unit tests的PaddlePaddle，可以：</p>
<div class="highlight-bash"><div class="highlight"><pre><span></span>➜  docker run -v <span class="k">$(</span><span class="nb">pwd</span><span class="k">)</span>:/paddle -e <span class="s2">&quot;WITH_GPU=OFF&quot;</span> -e <span class="s2">&quot;WITH_AVX=ON&quot;</span> -e <span class="s2">&quot;WITH_TEST=ON&quot;</span> paddle:dev
</pre></div>
</div>
<p>这个过程除了编译PaddlePaddle为 <code class="docutils literal"><span class="pre">./build/libpaddle.so</span></code>，并且输出一个 <code class="docutils literal"><span class="pre">./build/paddle.deb</span></code>文件之外，还会输出一个 <code class="docutils literal"><span class="pre">build/Dockerfile</span></code>。我们只需要运行下面命令把编译好的PaddlePaddle打包成一个<em>生产镜像</em>（<code class="docutils literal"><span class="pre">paddle:prod</span></code>）：</p>
<div class="highlight-bash"><div class="highlight"><pre><span></span>➜  docker build -t paddle:prod -f build/Dockerfile .
</pre></div>
</div>
<p>如果要运行所有的单元测试，可以用如下命令：</p>
<div class="highlight-bash"><div class="highlight"><pre><span></span>➜  docker run -it -v <span class="k">$(</span><span class="nb">pwd</span><span class="k">)</span>:/paddle paddle:dev bash -c <span class="s2">&quot;cd /paddle/build &amp;&amp; ctest&quot;</span>
</pre></div>
</div>
<p>关于构建和测试的更多信息，请参见<a class="reference external" href="https://github.com/PaddlePaddle/Paddle/blob/develop/doc/getstarted/build_and_install/docker_install_cn.rst">这篇文档</a>。</p>
</div>
<div class="section" id="commit">
<span id="commit"></span><h2>提交（commit）<a class="headerlink" href="#commit" title="永久链接至标题">¶</a></h2>
<p>接下来我们取消对 README.md 文件的改变，然后提交新添加的 test 文件。</p>
<div class="highlight-bash"><div class="highlight"><pre><span></span>➜  git checkout -- README.md
➜  git status
On branch <span class="nb">test</span>
Untracked files:
  <span class="o">(</span>use <span class="s2">&quot;git add &lt;file&gt;...&quot;</span> to include in what will be committed<span class="o">)</span>

    <span class="nb">test</span>

nothing added to commit but untracked files present <span class="o">(</span>use <span class="s2">&quot;git add&quot;</span> to track<span class="o">)</span>
➜  git add <span class="nb">test</span>
</pre></div>

<p>Git 每次提交代码，都需要写提交说明，这可以让其他人知道这次提交做了哪些改变，这可以通过<code class="docutils literal"><span class="pre">git</span> <span class="pre">commit</span></code> 完成。</p>

<span id="id9"></span><h2>提交代码的一些约定<a class="headerlink" href="#" title="永久链接至标题">¶</a></h2>
<p>为了使评审人在评审代码时更好地专注于代码本身，请您每次提交代码时，遵守以下约定：</p>
<ol class="simple">
<li>请保证Travis-CI 中单元测试能顺利通过。如果没过，说明提交的代码存在问题，评审人一般不做评审。</li>
<li>提交PUll Request前：<ul>
<li>请注意commit的数量：<ul>
<li>原因：如果仅仅修改一个文件但提交了十几个commit，每个commit只做了少量的修改，这会给评审人带来很大困扰。评审人需要逐一查看每个commit才能知道做了哪些修改，且不排除commit之间的修改存在相互覆盖的情况。</li>
<li>建议：每次提交时，保持尽量少的commit，可以通过<code class="docutils literal"><span class="pre">git</span> <span class="pre">commit</span> <span class="pre">--amend</span></code>补充上次的commit。对已经Push到远程仓库的多个commit，可以参考<a class="reference external" href="http://stackoverflow.com/questions/5667884/how-to-squash-commits-in-git-after-they-have-been-pushed">squash commits after push</a>。</li>
</ul>
</li>
<li>请注意每个commit的名称：应能反映当前commit的内容，不能太随意。</li>
</ul>
</li>
<li>如果解决了某个Issue的问题，请在该PUll Request的<strong>第一个</strong>评论框中加上：<code class="docutils literal"><span class="pre">fix</span> <span class="pre">#issue_number</span></code>，这样当该PUll Request被合并后，会自动关闭对应的Issue。关键词包括：close, closes, closed, fix, fixes, fixed, resolve, resolves, resolved，请选择合适的词汇。详细可参考<a class="reference external" href="https://help.github.com/articles/closing-issues-via-commit-messages">Closing issues via commit messages</a>。</li>
</ol>
<p>此外，在回复评审人意见时，请您遵守以下约定：</p>
<ol class="simple">
<li>评审人的每个意见都必须回复（这是开源社区的基本礼貌，别人帮了忙，应该说谢谢）：<ul>
<li>对评审意见同意且按其修改完的，给个简单的<code class="docutils literal"><span class="pre">Done</span></code>即可；</li>
<li>对评审意见不同意的，请给出您自己的反驳理由。</li>
</ul>
</li>
<li>如果评审意见比较多：<ul>
<li>请给出总体的修改情况。</li>
<li>请采用<a class="reference external" href="https://help.github.com/articles/reviewing-proposed-changes-in-a-pull-request/">start a review</a>进行回复，而非直接回复的方式。原因是每个回复都会发送一封邮件，会造成邮件灾难。</li>
</ul>
</li>
