<span id="paddlepaddle"></span><h1>PaddlePaddle发行规范<a class="headerlink" href="#paddlepaddle" title="Permalink to this headline">¶</a></h1>
<p>PaddlePaddle使用git-flow branching model做分支管理，使用<a class="reference external" href="http://semver.org/">Semantic Versioning</a>标准表示PaddlePaddle版本号。</p>
<p>PaddlePaddle每次发新的版本，遵循以下流程:</p>
<ol class="simple">
<li>从<code class="docutils literal"><span class="pre">develop</span></code>分支派生出新的分支，分支名为<code class="docutils literal"><span class="pre">release/版本号</span></code>。例如，<code class="docutils literal"><span class="pre">release/0.10.0</span></code></li>
<li>将新分支的版本打上tag，tag为<code class="docutils literal"><span class="pre">版本号rc.Patch号</span></code>。第一个tag为<code class="docutils literal"><span class="pre">0.10.0rc1</span></code>，第二个为<code class="docutils literal"><span class="pre">0.10.0rc2</span></code>，依次类推。</li>
<li>对这个版本的提交，做如下几个操作:</li>
</ol>
<ul>
<li><p class="first">使用Regression Test List作为检查列表，测试本次release的正确性。</p>
<ul>
<li><p class="first">如果失败，记录下所有失败的例子，在这个<code class="docutils literal"><span class="pre">release/版本号</span></code>分支中，修复所有bug后，Patch号加一，到第二步</p>
</li>
<li><p class="first">修改<code class="docutils literal"><span class="pre">python/setup.py.in</span></code>中的版本信息,并将<code class="docutils literal"><span class="pre">istaged</span></code>字段设为<code class="docutils literal"><span class="pre">True</span></code>。</p>
</li>
<li><p class="first">编译这个版本的python wheel包，并发布到pypi。</p>
<ul>
<li><p class="first">由于pypi.python.org目前遵循<a class="reference external" href="https://www.python.org/dev/peps/pep-0513">严格的命名规范PEP 513</a>，在使用twine上传之前，需要重命名wheel包中platform相关的后缀，比如将<code class="docutils literal"><span class="pre">linux_x86_64</span></code>修改成<code class="docutils literal"><span class="pre">manylinux1_x86_64</span></code>。</p>
</li>
<li><p class="first">pypi上的package名称为paddlepaddle和paddlepaddle_gpu，如果要上传GPU版本的包，需要修改build/python/setup.py中，name: &#8220;paddlepaddle_gpu&#8221;并重新打包wheel包：<code class="docutils literal"><span class="pre">python</span> <span class="pre">setup.py</span> <span class="pre">bdist_wheel</span></code>。</p>
</li>
<li><p class="first">上传方法：</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">cd</span> <span class="n">build</span><span class="o">/</span><span class="n">python</span>
<span class="n">pip</span> <span class="n">install</span> <span class="n">twine</span>
<span class="n">twine</span> <span class="n">upload</span> <span class="n">dist</span><span class="o">/</span><span class="p">[</span><span class="n">package</span> <span class="n">to</span> <span class="n">upload</span><span class="p">]</span>
</pre></div>
</div>
</li>
<li><p class="first">编译这个版本的Docker发行镜像，发布到dockerhub。如果失败，修复Docker编译镜像问题，Patch号加一，返回第二步</p>
</li>
</ul>
</li>
</ul>
</li>
</ul>
<ol class="simple">
<li>第三步完成后，将<code class="docutils literal"><span class="pre">release/版本号</span></code>分支合入master分支，并删除<code class="docutils literal"><span class="pre">release/版本号</span></code>分支。将master分支的合入commit打上tag，tag为<code class="docutils literal"><span class="pre">版本号</span></code>。同时再将<code class="docutils literal"><span class="pre">master</span></code>分支合入<code class="docutils literal"><span class="pre">develop</span></code>分支。最后删除<code class="docutils literal"><span class="pre">release/版本号</span></code>分支。</li>
<li>协同完成Release Note的书写</li>
</ol>
<p>需要注意的是:</p>
<ul class="simple">
<li><code class="docutils literal"><span class="pre">release/版本号</span></code>分支一旦建立，一般不允许再从<code class="docutils literal"><span class="pre">develop</span></code>分支合入<code class="docutils literal"><span class="pre">release/版本号</span></code>。这样保证<code class="docutils literal"><span class="pre">release/版本号</span></code>分支功能的封闭，方便测试人员测试PaddlePaddle的行为。</li>
<li>在<code class="docutils literal"><span class="pre">release/版本号</span></code>分支存在的时候，如果有bugfix的行为，需要将bugfix的分支同时merge到<code class="docutils literal"><span class="pre">master</span></code>, <code class="docutils literal"><span class="pre">develop</span></code>和<code class="docutils literal"><span class="pre">release/版本号</span></code>这三个分支。</li>

使用<code class="docutils literal"><span class="pre">twine</span></code>工具上传即可。</p>
<p><img src="ci_build_whl.png"></p>
<ul class="simple">
<li>注：CI环境使用 https://github.com/PaddlePaddle/buildtools 这里的DockerImage作为编译环境以支持更多的Linux
发型版，如果需要手动编译，也可以使用这些镜像。这些镜像也可以从 https://hub.docker.com/r/paddlepaddle/paddle_manylinux_devel/tags/ 下载得到。</li>
<li>pypi不支持覆盖上传，所以一个版本号的wheel包发布之后，不可以更改。下一个wheel包需要更新版本号才可以上传。</li>

<span id="id1"></span><h2>PaddlePaddle 分支规范<a class="headerlink" href="#paddlepaddle" title="Permalink to this headline">¶</a></h2>
<p>PaddlePaddle开发过程使用<a class="reference external" href="http://nvie.com/posts/a-successful-git-branching-model/">git-flow</a>分支规范，并适应github的特性做了一些区别。</p>
<ul class="simple">
<li>PaddlePaddle的主版本库遵循<a class="reference external" href="http://nvie.com/posts/a-successful-git-branching-model/">git-flow</a>分支规范。其中:<ul>
<li><code class="docutils literal"><span class="pre">master</span></code>分支为稳定(stable branch)版本分支。每一个<code class="docutils literal"><span class="pre">master</span></code>分支的版本都是经过单元测试和回归测试的版本。</li>
<li><code class="docutils literal"><span class="pre">develop</span></code>分支为开发(develop branch)版本分支。每一个<code class="docutils literal"><span class="pre">develop</span></code>分支的版本都经过单元测试，但并没有经过回归测试。</li>
<li><code class="docutils literal"><span class="pre">release/版本号</span></code>分支为每一次Release时建立的临时分支。在这个阶段的代码正在经历回归测试。</li>
</ul>
</li>
<li>其他用户的fork版本库并不需要严格遵守<a class="reference external" href="http://nvie.com/posts/a-successful-git-branching-model/">git-flow</a>分支规范，但所有fork的版本库的所有分支都相当于特性分支。<ul>
<li>建议，开发者fork的版本库使用<code class="docutils literal"><span class="pre">develop</span></code>分支同步主版本库的<code class="docutils literal"><span class="pre">develop</span></code>分支</li>
<li>建议，开发者fork的版本库中，再基于<code class="docutils literal"><span class="pre">develop</span></code>版本fork出自己的功能分支。</li>
<li>当功能分支开发完毕后，向PaddlePaddle的主版本库提交<code class="docutils literal"><span class="pre">Pull</span> <span class="pre">Reuqest</span></code>，进而进行代码评审。<ul>
<li>在评审过程中，开发者修改自己的代码，可以继续在自己的功能分支提交代码。</li>
</ul>
</li>
</ul>
</li>
<li>BugFix分支也是在开发者自己的fork版本库维护，与功能分支不同的是，BugFix分支需要分别给主版本库的<code class="docutils literal"><span class="pre">master</span></code>、<code class="docutils literal"><span class="pre">develop</span></code>与可能有的<code class="docutils literal"><span class="pre">release/版本号</span></code>分支，同时提起<code class="docutils literal"><span class="pre">Pull</span> <span class="pre">Request</span></code>。</li>
