<p>因为 Git 保存的不是文件的变化或者差异,而是一系列不同时刻的 快照 。</p>
|
|||
|
<p>所以在进行提交操作时,Git 会保存一个提交对象(commit object)。该提交对象会包含一个指向暂存内容快照的指针,且还包含了作者的姓名和邮箱提交时输入的信息以及指向它的父对象的指针。 首次提交产生的提交对象没有父对象,普通提交操作产生的提交对象有一个父对象, 而由多个分支合并产生的提交对象有多个父对象。</p>
|
|||
|
<p><strong>Git 的分支,其实本质上仅仅是指向提交对象的可变指针。</strong></p>

<p>正在此时,你突然接到一个电话说有个很严重的问题需要紧急修补。 你将按照如下方式来处理:</p>
|
|||
|
<ol>
|
|||
|
<li>切换到你的线上分支(production branch)。</li>
|
|||
|
<li>为这个紧急任务新建一个分支,并在其中修复它。</li>
|
|||
|
<li>在测试通过之后,切换回线上分支,然后合并这个修补分支,最后将改动推送到线上分支。</li>
|
|||
|
<li>切换回你最初工作的分支上,继续工作。</li>
|
|||
|
</ol>

|

<p>首先,我们假设你正在你的项目上工作,并且在 master 分支上已经有了一些提交。</p>
|
|||
|
<p>现在,你为实现某个新的需求,创建一个分支 iss53。</p>
|

|
|||
|
<p>当我们做了一些提交的时候,iss53 分支在向前推进。</p>
|
|||
|
<p>现在你接到那个电话,有个紧急问题等待你来解决,现在要做的就是切换回主分支。</p>
|

<figure data-rehype-pretty-code-figure><pre tabindex="0" data-language="shell" data-theme="github-light github-dark"><code data-language="shell" data-theme="github-light github-dark" style="display:grid;"><span data-line><span style="--shiki-light:#6F42C1;--shiki-dark:#B392F0;">git</span><span style="--shiki-light:#032F62;--shiki-dark:#9ECBFF;"> switch</span><span style="--shiki-light:#032F62;--shiki-dark:#9ECBFF;"> master</span></span></code></pre></figure>
|

<p>接下来,你要修复这个紧急问题。新建一个 hotfix 分支,直至问题解决。</p>

|
|||
|
<p>然后将 hotfix 分支合并回你的 master 分支来部署线上。</p>
|
|||
|
<figure data-rehype-pretty-code-figure><pre tabindex="0" data-language="shell" data-theme="github-light github-dark"><code data-language="shell" data-theme="github-light github-dark" style="display:grid;"><span data-line><span style="--shiki-light:#6F42C1;--shiki-dark:#B392F0;">git</span><span style="--shiki-light:#032F62;--shiki-dark:#9ECBFF;"> switch</span><span style="--shiki-light:#032F62;--shiki-dark:#9ECBFF;"> master</span></span>

|
|||
|
<p>当你试图合并两个分支时, 如果顺着一个分支走下去能够到达另一个分支,那么 Git 在合并两者的时候, 只会简单的将指针向前推进(指针右移),因为这种情况下的合并操作没有需要解决的分歧——这就叫做 “快进(fast-forward)”。</p>
|
|||
|
<p>此时,hotfix 分支已经不需要了,可以将它删除。</p>
|
|||
|
<figure data-rehype-pretty-code-figure><pre tabindex="0" data-language="shell" data-theme="github-light github-dark"><code data-language="shell" data-theme="github-light github-dark" style="display:grid;"><span data-line><span style="--shiki-light:#6F42C1;--shiki-dark:#B392F0;">git</span><span style="--shiki-light:#032F62;--shiki-dark:#9ECBFF;"> branch</span><span style="--shiki-light:#005CC5;--shiki-dark:#79B8FF;"> -d</span><span style="--shiki-light:#032F62;--shiki-dark:#9ECBFF;"> hotfix</span></span></code></pre></figure>
|
|||
|
<p>现在你切回你正在工作的分支,继续你的工作,并且拥有了新的提交。</p>
|
|||
|
<p>假设这时你已经完成了 iss53 的需求,需要将 iss53 分支合并入 master 分支。</p>
|
|||
|
<figure data-rehype-pretty-code-figure><pre tabindex="0" data-language="shell" data-theme="github-light github-dark"><code data-language="shell" data-theme="github-light github-dark" style="display:grid;"><span data-line><span style="--shiki-light:#6F42C1;--shiki-dark:#B392F0;">git</span><span style="--shiki-light:#032F62;--shiki-dark:#9ECBFF;"> switch</span><span style="--shiki-light:#032F62;--shiki-dark:#9ECBFF;"> master</span></span>

<span data-line><span style="--shiki-light:#6F42C1;--shiki-dark:#B392F0;">git</span><span style="--shiki-light:#032F62;--shiki-dark:#9ECBFF;"> merge</span><span style="--shiki-light:#032F62;--shiki-dark:#9ECBFF;"> iss53</span></span></code></pre></figure>
|
|||
|
<p>这和之前合并 hotfix 分支的时候看起来有点不一样。</p>
|
|||
|
<p>在这种情况下,你的开发历史从一个更早的地方开始分叉开来(diverged)。 因为,master 分支所在提交并不是 iss53 分支所在提交的直接祖先,Git 不得不做一些额外的工作。 出现这种情况的时候,Git 会使用两个分支的末端所指的快照以及这两个分支的公共祖先,做一个简单的三方合并。</p>

<p>有时候合并操作并不会如此顺利,因为如果涉及到同一个文件的同一处,就会在合并时产生冲突。此时 Git 做了合并,但是没有自动地创建一个新的合并提交。 Git 会暂停下来,等待你去解决合并产生的冲突。</p>
|
|||
|
<p>任何因包含合并冲突而有待解决的文件,都会以未合并状态标识出来。 Git 会在有冲突的文件中加入标准的冲突解决标记,这样你可以打开这些包含冲突的文件然后手动解决冲突。</p>
|
|||
|
<p>出现冲突的文件会包含一些特殊区段像下面这个样子:</p>

<p>它的原理是首先找到这两个分支(假设当前分支 experiment、变基操作的目标基底分支 master) 的最近共同祖先,然后对比当前分支相对于该祖先的历次提交,提取相应的修改并存为临时文件, 然后将当前分支指向目标基底, 最后以此将之前另存为临时文件的修改依序应用。</p>

<p>在对两个分支进行变基时,所生成的“重放”并不一定要在目标分支上应用,你也可以指定另外的一个分支进行</p>
|
|||
|
<p>应用。</p>
|
|||
|
<p>你从 master 分支创建了一个 server 分支,添加功能并提交后。又基于提交后的 server 分支创建了 client 分支,同样添加功能并提交后。你回到了 server 分支,继续添加功能并提交。假设你希望将 client 中的修改合并到主分支并发布,但暂时并不想合并 server 中的修改,因为它们还需要经过更全面的测试。</p>
|
|||
|
<p>这时,你就可以使用 git rebase 命令的 —onto 选项, 选中在 client 分支里但不在 server 分支里的修改,将它们在 master 分支上重放。</p>

<p>如果提交存在于你的仓库之外,而别人可能基于这些提交进行开发,那么不要执行变基。</p>
|
|||
|
<p>如果你遵循这条金科玉律,就不会出差错。 否则,人民群众会仇恨你,你的朋友和家人也会嘲笑你,唾你。</p>

<p>至此,你已在实战中学习了变基和合并的用法,你一定会想问,到底哪种方式更好。 在回答这个问题之前,让我们退后一步,想讨论一下提交历史到底意味着什么。</p>
|
|||
|
<p>有一种观点认为,仓库的提交历史即是 记录实际发生过什么。 它是针对历史的文档,本身就有价值,不能乱改。 从这个角度看来,改变提交历史是一种亵渎,你使用 谎言 掩盖了实际发生过的事情。 如果由合并产生的提</p>
|
|||
|
<p>交历史是一团糟怎么办? 既然事实就是如此,那么这些痕迹就应该被保留下来,让后人能够查阅。另一种观点则正好相反,他们认为提交历史是 项目过程中发生的事。 没人会出版一本书的第一版草稿,软件维护手册也是需要反复修订才能方便使用。 持这一观点的人会使用 rebase 及 filter-branch 等工具来编写故事,怎么方便后来的读者就怎么写。</p>
|
|||
|
<p>现在,让我们回到之前的问题上来,到底合并还是变基好?希望你能明白,这并没有一个简单的答案。 Git 是一个非常强大的工具,它允许你对提交历史做许多事情,但每个团队、每个项目对此的需求并不相同。 既然你已经分别学习了两者的用法,相信你能够根据实际情况作出明智的选择。</p>
|
|||
|
<p>总的原则是,只对尚未推送或分享给别人的本地修改执行变基操作清理历史, 从不对已推送至别处的提交执行变基操作,这样,你才能享受到两种方式带来的便利。</p></article><hr/><div class="page-footer"></div></div><div class="right sidebar"><div class="graph"><h3>关系图谱</h3><div class="graph-outer"><div id="graph-container" data-cfg="{"drag":true,"zoom":true,"depth":1,"scale":1.1,"repelForce":0.5,"centerForce":0.3,"linkDistance":30,"fontSize":0.6,"opacityScale":1,"showTags":true,"removeTags":[],"focusOnHover":false}"></div><button id="global-graph-icon" aria-label="Global Graph"><svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 55 55" fill="currentColor" xml:space="preserve"><path d="M49,0c-3.309,0-6,2.691-6,6c0,1.035,0.263,2.009,0.726,2.86l-9.829,9.829C32.542,17.634,30.846,17,29,17
