+        <p>熟悉我的人（谁熟悉你啊🙄）知道我以前写过 PHP，虽然现在在工作中没用到了，但是自己的一些小工具还是会用 PHP 来写，但是在 Mac 碰到了一个环境相关的问题，因为我也是个更新狂魔，用了 brew 之后因为 gfw 的原因，如果长时间不更新，有时候要装一个用它装一个软件的话，前置的更新耗时就会让人非常头大，所以我基本会隔天 update 一下，但是这样会带来一个很心烦的问题，就是像这样，因为我是要用一个固定版本的 PHP，如果一直升需要一直配扩展啥的也很麻烦，如果一直升级 PHP 到最新版可能会比较少碰到这个问题</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.64.dylib</span><br></pre></td></tr></table></figure>
+<p>这是什么鬼啊，然后我去这个目录下看了下，已经都是libicui18n.67.dylib了，而且它没有把原来的版本保留下来，首先这个是个叫 icu4c是啥玩意，谷歌了一下</p>
+<blockquote>
+<p>ICU4C是ICU在C/C++平台下的版本, ICU(International Component for Unicode)是基于”IBM公共许可证”的，与开源组织合作研究的, 用于支持软件国际化的开源项目。ICU4C提供了C/C++平台强大的国际化开发能力，软件开发者几乎可以使用ICU4C解决任何国际化的问题，根据各地的风俗和语言习惯，实现对数字、货币、时间、日期、和消息的格式化、解析，对字符串进行大小写转换、整理、搜索和排序等功能，必须一提的是，ICU4C提供了强大的BIDI算法，对阿拉伯语等BIDI语言提供了完善的支持。</p>
+</blockquote>
+<p>然后首先想到的解决方案就是能不能我使用<code>brew install icu4c@64</code>来重装下原来的版本，发现不行，并木有，之前的做法就只能是去网上把 64 的下载下来，然后放到这个目录，比较麻烦不智能，虽然没抱着希望在谷歌着，不过这次竟然给我找到了一个我认为非常 nice 的解决方案，因为是在 Stack Overflow 找到的，本着写给像我这样的小小白看的，那就稍微翻译一下<br>第一步，我们到 brew的目录下</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">cd $(brew --prefix)/Homebrew/Library/Taps/homebrew/homebrew-core/Formula</span><br></pre></td></tr></table></figure>
+<p>这个可以理解为是 maven 的 pom 文件，不过有很多不同之处，使用ruby 写的，然后一个文件对应一个组件或者软件，那我们看下有个叫icu4c.rb的文件，<br>第二步看看它的提交历史</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">git log --follow icu4c.rb</span><br></pre></td></tr></table></figure>
+<p>在 git log 的海洋中寻找，寻找它的(64版本)的身影<br><img data-src="https://mystore-1255223546.cos.ap-chengdu.myqcloud.com/uPic/YzS7vN.png" alt=""><br>第三步注意这三个红框，Stack Overflow 给出来的答案这一步是找到这个 commit id 直接切出一个新分支</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">git checkout -b icu4c-63 e7f0f10dc63b1dc1061d475f1a61d01b70ef2cb7</span><br></pre></td></tr></table></figure>
+<p>其实注意 commit id 旁边的红框，这个是有tag 的，可以直接</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">git checkout icu4c-64</span><br></pre></td></tr></table></figure>
+<p>PS: 因为我的问题是出在 64 的问题，Stack Overflow 回答的是 63 的，反正是一样的解决方法<br>第四部，切回去之后我们就可以用 brew 提供的基于文件的安装命令来重新装上 64 版本</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">brew reinstall ./icu4c.rb</span><br></pre></td></tr></table></figure>
+<p>然后就是第五步，切换版本</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">brew switch icu4c 64.2</span><br></pre></td></tr></table></figure>
+<p>最后把分支切回来</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">git checkout master</span><br></pre></td></tr></table></figure>
+<p>是不是感觉很厉害的解决方法，大佬还提供了一个更牛的，直接写个 zsh 方法</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br></pre></td><td class="code"><pre><span class="line"><span class="meta">#</span><span class="bash"> zsh</span></span><br><span class="line">function hiicu64() &#123;</span><br><span class="line">  local last_dir=$(pwd)</span><br><span class="line"></span><br><span class="line">  cd $(brew --prefix)/Homebrew/Library/Taps/homebrew/homebrew-core/Formula</span><br><span class="line">  git checkout icu4c-4</span><br><span class="line">  brew reinstall ./icu4c.rb</span><br><span class="line">  brew switch icu4c 64.2</span><br><span class="line">  git checkout master</span><br><span class="line"></span><br><span class="line">  cd $last_dir</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>
+<p>对应自己的版本改改版本号就可以了，非常好用。</p>

+          <p>熟悉我的人（谁熟悉你啊🙄）知道我以前写过 PHP，虽然现在在工作中没用到了，但是自己的一些小工具还是会用 PHP 来写，但是在 Mac 碰到了一个环境相关的问题，因为我也是个更新狂魔，用了 brew 之后因为 gfw 的原因，如果长时间不更新，有时候要装一个用它装一个软件的话，前置的更新耗时就会让人非常头大，所以我基本会隔天 update 一下，但是这样会带来一个很心烦的问题，就是像这样，因为我是要用一个固定版本的 PHP，如果一直升需要一直配扩展啥的也很麻烦，如果一直升级 PHP 到最新版可能会比较少碰到这个问题</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.64.dylib</span><br></pre></td></tr></table></figure>
+<p>这是什么鬼啊，然后我去这个目录下看了下，已经都是libicui18n.67.dylib了，而且它没有把原来的版本保留下来，首先这个是个叫 icu4c是啥玩意，谷歌了一下</p>
+<blockquote>
+<p>ICU4C是ICU在C/C++平台下的版本, ICU(International Component for Unicode)是基于”IBM公共许可证”的，与开源组织合作研究的, 用于支持软件国际化的开源项目。ICU4C提供了C/C++平台强大的国际化开发能力，软件开发者几乎可以使用ICU4C解决任何国际化的问题，根据各地的风俗和语言习惯，实现对数字、货币、时间、日期、和消息的格式化、解析，对字符串进行大小写转换、整理、搜索和排序等功能，必须一提的是，ICU4C提供了强大的BIDI算法，对阿拉伯语等BIDI语言提供了完善的支持。</p>
+</blockquote>
+<p>然后首先想到的解决方案就是能不能我使用<code>brew install icu4c@64</code>来重装下原来的版本，发现不行，并木有，之前的做法就只能是去网上把 64 的下载下来，然后放到这个目录，比较麻烦不智能，虽然没抱着希望在谷歌着，不过这次竟然给我找到了一个我认为非常 nice 的解决方案，因为是在 Stack Overflow 找到的，本着写给像我这样的小小白看的，那就稍微翻译一下<br>第一步，我们到 brew的目录下</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">cd $(brew --prefix)/Homebrew/Library/Taps/homebrew/homebrew-core/Formula</span><br></pre></td></tr></table></figure>
+<p>这个可以理解为是 maven 的 pom 文件，不过有很多不同之处，使用ruby 写的，然后一个文件对应一个组件或者软件，那我们看下有个叫icu4c.rb的文件，<br>第二步看看它的提交历史</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">git log --follow icu4c.rb</span><br></pre></td></tr></table></figure>
+<p>在 git log 的海洋中寻找，寻找它的(64版本)的身影<br><img data-src="https://mystore-1255223546.cos.ap-chengdu.myqcloud.com/uPic/YzS7vN.png" alt=""><br>第三步注意这三个红框，Stack Overflow 给出来的答案这一步是找到这个 commit id 直接切出一个新分支</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">git checkout -b icu4c-63 e7f0f10dc63b1dc1061d475f1a61d01b70ef2cb7</span><br></pre></td></tr></table></figure>
+<p>其实注意 commit id 旁边的红框，这个是有tag 的，可以直接</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">git checkout icu4c-64</span><br></pre></td></tr></table></figure>
+<p>PS: 因为我的问题是出在 64 的问题，Stack Overflow 回答的是 63 的，反正是一样的解决方法<br>第四部，切回去之后我们就可以用 brew 提供的基于文件的安装命令来重新装上 64 版本</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">brew reinstall ./icu4c.rb</span><br></pre></td></tr></table></figure>
+<p>然后就是第五步，切换版本</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">brew switch icu4c 64.2</span><br></pre></td></tr></table></figure>
+<p>最后把分支切回来</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">git checkout master</span><br></pre></td></tr></table></figure>
+<p>是不是感觉很厉害的解决方法，大佬还提供了一个更牛的，直接写个 zsh 方法</p>
+<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br></pre></td><td class="code"><pre><span class="line"><span class="meta">#</span><span class="bash"> zsh</span></span><br><span class="line">function hiicu64() &#123;</span><br><span class="line">  local last_dir=$(pwd)</span><br><span class="line"></span><br><span class="line">  cd $(brew --prefix)/Homebrew/Library/Taps/homebrew/homebrew-core/Formula</span><br><span class="line">  git checkout icu4c-4</span><br><span class="line">  brew reinstall ./icu4c.rb</span><br><span class="line">  brew switch icu4c 64.2</span><br><span class="line">  git checkout master</span><br><span class="line"></span><br><span class="line">  cd $last_dir</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>
+<p>对应自己的版本改改版本号就可以了，非常好用。</p>

-          <p>看完前面两篇水文之后，感觉不得不来分析下 mysql 的锁了，其实前面说到幻读的时候是有个前提没提到的，比如一个<code>select * from table1 where id  = 1</code>这种查询语句其实是不会加传说中的锁的，当然这里是指在 RR 或者 RC 隔离级别下，<br>看一段 mysql官方文档</p>
-<blockquote>
-<p><code>SELECT ... FROM</code> is a consistent read, reading a snapshot of the database and setting no locks unless the transaction isolation level is set to SERIALIZABLE. For SERIALIZABLE level, the search sets shared next-key locks on the index records it encounters. However, only an index record lock is required for statements that lock rows using a unique index to search for a unique row.   </p>
-</blockquote>
-<p>纯粹的这种一致性读，实际读取的是快照，也就是基于 read view 的读取方式，除非当前隔离级别是SERIALIZABLE<br>但是对于以下几类</p>
-<ul>
-<li><code>select * from table where ? lock in share mode;</code></li>
-<li><code>select * from table where ? for update;</code></li>
-<li><code>insert into table values (...);</code></li>
-<li><code>update table set ? where ?;</code></li>
-<li><code>delete from table where ?;</code>  </li>
-</ul>
-<p>除了第一条是 S 锁之外，其他都是 X 排他锁，这边在顺带下，S 锁表示共享锁， X 表示独占锁，同为 S 锁之间不冲突，S 与 X，X 与 S，X 与 X 之间都冲突，也就是加了前者，后者就加不上了<br>我们知道对于 RC 级别会出现幻读现象，对于 RR 级别不会出现，主要的区别是 RR 级别下对于以上的加锁读取都根据情况加上了 gap 锁，那么是不是 RR 级别下以上所有的都是要加 gap 锁呢，当然不是<br>举个例子，RR 事务隔离级别下，table1 有个主键id 字段<br><code>select * from table1 where id = 10 for update</code><br>这条语句要加 gap 锁吗？<br>答案是不需要，这里其实算是我看了这么久的一点自己的理解，啥时候要加 gap 锁，判断的条件是根据我查询的数据是否会因为不加 gap 锁而出现数量的不一致，我上面这条查询语句，在什么情况下会出现查询结果数量不一致呢，只要在这条记录被更新或者删除的时候，有没有可能我第一次查出来一条，第二次变成两条了呢，不可能，因为是主键索引。<br>再变更下这个题的条件，当 id 不是主键，但是是唯一索引，这样需要怎么加锁，注意问题是怎么加锁，不是需不需要加 gap 锁，这里呢就是稍微延伸一下，把聚簇索引（主键索引）和二级索引带一下，当 id 不是主键，说明是个二级索引，但是它是唯一索引，体会下，首先对于 id = 10这个二级索引肯定要加锁，要不要锁 gap 呢，不用，因为是唯一索引，id = 10 只可能有这一条记录，然后呢，这样是不是就好了，还不行，因为啥，因为它是二级索引，对应的主键索引的记录才是真正的数据，万一被更新掉了咋办，所以在 id = 10 对应的主键索引上也需要加上锁（默认都是 record lock行锁），那主键索引上要不要加 gap 呢，也不用，也是精确定位到这一条记录<br>最后呢，当 id 不是主键，也不是唯一索引，只是个普通的索引，这里就需要大名鼎鼎的 gap 锁了，<br>是时候画个图了<br><img data-src="https://mystore-1255223546.cos.ap-chengdu.myqcloud.com/uPic/WX20200510-1126082x.png" alt=""><br>其实核心的目的还是不让这个 id=10 的记录不会出现幻读，那么就需要在 id 这个索引上加上三个 gap 锁，主键索引上就不用了，在 id 索引上已经控制住了id = 10 不会出现幻读，主键索引上这两条对应的记录已经锁了，所以就这样 OK 了</p>

+          <p>看完前面两篇水文之后，感觉不得不来分析下 mysql 的锁了，其实前面说到幻读的时候是有个前提没提到的，比如一个<code>select * from table1 where id  = 1</code>这种查询语句其实是不会加传说中的锁的，当然这里是指在 RR 或者 RC 隔离级别下，<br>看一段 mysql官方文档</p>
+<blockquote>
+<p><code>SELECT ... FROM</code> is a consistent read, reading a snapshot of the database and setting no locks unless the transaction isolation level is set to SERIALIZABLE. For SERIALIZABLE level, the search sets shared next-key locks on the index records it encounters. However, only an index record lock is required for statements that lock rows using a unique index to search for a unique row.   </p>
+</blockquote>
+<p>纯粹的这种一致性读，实际读取的是快照，也就是基于 read view 的读取方式，除非当前隔离级别是SERIALIZABLE<br>但是对于以下几类</p>
+<ul>
+<li><code>select * from table where ? lock in share mode;</code></li>
+<li><code>select * from table where ? for update;</code></li>
+<li><code>insert into table values (...);</code></li>
+<li><code>update table set ? where ?;</code></li>
+<li><code>delete from table where ?;</code>  </li>
+</ul>
+<p>除了第一条是 S 锁之外，其他都是 X 排他锁，这边在顺带下，S 锁表示共享锁， X 表示独占锁，同为 S 锁之间不冲突，S 与 X，X 与 S，X 与 X 之间都冲突，也就是加了前者，后者就加不上了<br>我们知道对于 RC 级别会出现幻读现象，对于 RR 级别不会出现，主要的区别是 RR 级别下对于以上的加锁读取都根据情况加上了 gap 锁，那么是不是 RR 级别下以上所有的都是要加 gap 锁呢，当然不是<br>举个例子，RR 事务隔离级别下，table1 有个主键id 字段<br><code>select * from table1 where id = 10 for update</code><br>这条语句要加 gap 锁吗？<br>答案是不需要，这里其实算是我看了这么久的一点自己的理解，啥时候要加 gap 锁，判断的条件是根据我查询的数据是否会因为不加 gap 锁而出现数量的不一致，我上面这条查询语句，在什么情况下会出现查询结果数量不一致呢，只要在这条记录被更新或者删除的时候，有没有可能我第一次查出来一条，第二次变成两条了呢，不可能，因为是主键索引。<br>再变更下这个题的条件，当 id 不是主键，但是是唯一索引，这样需要怎么加锁，注意问题是怎么加锁，不是需不需要加 gap 锁，这里呢就是稍微延伸一下，把聚簇索引（主键索引）和二级索引带一下，当 id 不是主键，说明是个二级索引，但是它是唯一索引，体会下，首先对于 id = 10这个二级索引肯定要加锁，要不要锁 gap 呢，不用，因为是唯一索引，id = 10 只可能有这一条记录，然后呢，这样是不是就好了，还不行，因为啥，因为它是二级索引，对应的主键索引的记录才是真正的数据，万一被更新掉了咋办，所以在 id = 10 对应的主键索引上也需要加上锁（默认都是 record lock行锁），那主键索引上要不要加 gap 呢，也不用，也是精确定位到这一条记录<br>最后呢，当 id 不是主键，也不是唯一索引，只是个普通的索引，这里就需要大名鼎鼎的 gap 锁了，<br>是时候画个图了<br><img data-src="https://mystore-1255223546.cos.ap-chengdu.myqcloud.com/uPic/WX20200510-1126082x.png" alt=""><br>其实核心的目的还是不让这个 id=10 的记录不会出现幻读，那么就需要在 id 这个索引上加上三个 gap 锁，主键索引上就不用了，在 id 索引上已经控制住了id = 10 不会出现幻读，主键索引上这两条对应的记录已经锁了，所以就这样 OK 了</p>

-<p>看到这里的e2的排序值是null，在Comparator中如果要正常运行的话，就得判空之类的，这里有两点需要，一个是不想写这个MyComparator，然后也没那么好排除掉list里排序值，那么有什么办法能解决这种问题呢，应该说java的这方面真的是很强大</p>

+<p>看到这里的e2的排序值是null，在Comparator中如果要正常运行的话，就得判空之类的，这里有两点需要，一个是不想写这个MyComparator，然后也没那么好排除掉list里排序值，那么有什么办法能解决这种问题呢，应该说java的这方面真的是很强大</p>

-          <p>寄生虫这部电影在获得奥斯卡之前就有关注了，豆瓣评分很高，一开始看到这个片名以为是像《铁线虫入侵》那种灾难片，后来看到男主，宋康昊，也是老面孔了，从高中时候在学校操场组织看的《汉江怪物》，有点二的感觉，后来在大学寝室电脑上重新看的时候，室友跟我说是韩国国宝级演员，真人不可貌相，感觉是个呆子的形象。</p>
-<p>但是你说这不是个灾难片，而是个反映社会问题的，就业比较容易往这个方向猜，只是剧情会是怎么样的，一时也没啥头绪，后来不知道哪里看了下一个剧情透露，是一个穷人给富人做家教，然后把自己一家都带进富人家，如果是这样的话可能会把这个怎么带进去作为一个主线，不过事实告诉我，这没那么重要，从第一步朋友的介绍，就显得无比顺利，要去当家教了，作为一个穷成这样的人，瞬间转变成一个衣着得体，言行举止都没让富人家看出破绽的延世大学学生，这真的挺难让人理解，所谓江山易改，本性难移，还有就是这人也正好有那么好能力去辅导，并且诡异的是，多惠也是瞬间就喜欢上了男主，多惠跟将男主介绍给她做家教，也就是多惠原来的家教敏赫，应该也有不少的相处时间，这变了有点大了吧，当然这里也可能因为时长需要，如果说这一点是因为时长，那可能我所有的槽点都是因为这个吧，因为我理解的应该是把家里的人如何一步步地带进富人家，这应该是整个剧情的一个需要更多铺垫去克服这个矛盾点，有时候也想过如果我去当导演，是能拍出个啥，没这个机会，可能有也会是很扯淡的，当然这也不能阻拦我谈谈对这个点的一些看法，毕竟评价一台电冰箱不是说我必须得自己会制冷对吧，这大概是我觉得这个电影的第一个槽点，接下去接二连三的，就是我说的这个最核心的矛盾点，不知道谁说过，这种影视剧应该是源自于生活又高于生活，越是好的作品，越要接近生活，这样子才更能有感同身受。</p>
-<p>接下去的点是金基宇介绍金基婷去给多颂当美术家教，这一步又是我理解的败笔吧，就怎么说呢，没什么铺垫，突然从一个社会底层的穷姑娘，转变成一个气场爆表，把富人家太太唬得一愣一愣的，如果说富太太是比较简单无脑的，那富人自己应该是比较有见识而且是做 IT 的，给自己儿子女儿做家教的，查查底细也很正常吧，但是啥都没有，然后呢，她又开始耍司机的心机了，真的是莫名其妙了，司机真的很惨，窈窕淑女君子好逑，而且这个操作也让我摸不着头脑，这是多腹黑并且有经验才会这么操作，脱内裤真的是让我看得一愣愣的，更看得我一愣一愣的，富人竟然也完全按着这个思路去想了，完全没有别的可能呢，甚至可以去查下行车记录仪或者怎样的，或者有没有毛发体液啥的去检验下，毕竟金基婷也乘坐过这辆车，但是最最让我不懂的还是脱内裤这个操作，究竟是什么样的人才会的呢，值得思考。</p>
-<p>金基泽和忠淑的点也是比较奇怪，首先是金基泽，引起最后那个杀人事件的一个由头，大部分观点都是人为朴社长在之前跟老婆啪啪啪的时候说金基泽的身上有股乘地铁的人的味道，简而言之就是穷人的味道，还有去雯光丈夫身下拿钥匙是对金基泽和雯光丈夫身上的味道的鄙夷，可是这个原因真的站不住脚，即使是同样经济水平，如果身上有比较重的异味，背后讨论下，或者闻到了比较重的味道，有不适的表情和动作很正常吧，像雯光丈夫，在地下室里呆了那么久，身上有异味并且比较重太正常了，就跟在厕所呆久了不会觉得味道大，但是从没味道的地方一进有点味道的厕所就会觉得异样，略尴尬的理由；再说忠淑呢，感觉是太厉害了，能胜任这么一家有钱人的各种挑剔的饮食口味要求的保姆职位，也是让人看懵逼了，看到了不禁想到一个问题，这家人开头是那么地穷，不堪，突然转变成这么地像骗子家族，如果有这么好的骗人能力，应该不会到这种地步吧，如果真的是那么穷，没能力，没志气，又怎么会突然变成这么厉害呢，一家人各司其职，把富人家唬得团团转，而这个前提是，这些人的确能胜任这四个位置，这就是我非常不能理解的点。</p>
-<p>然后说回这个标题，寄生虫，不知道是不是翻译过来不准确，如果真的是叫寄生虫的话，这个寄生虫智商未免也太低了，没有像新冠那样机制，致死率低一点，传染能力强一点，潜伏期也能传染，这个寄生虫第一次受到免疫系统的攻击就自爆了；还有呢，作为一个社会比较低层的打工者，乡下人，对这个审题也是不太审的清，是指这一家人是社会的寄生虫，不思进取，并且死的应该，富人是傻白甜，又有钱又善良，这是给有钱人洗地了还是啥，这个奥斯卡真不知道是怎么得的，总觉得奥斯卡，甚至低一点，豆瓣，得奖的，评分高的都是被一群“精英党”把持的，有黑人主角的，得分高；有同性恋的，得分高；结局惨的，得分高；看不懂的，得分高；就像肖申克的救赎，真不知道是哪里好了，最近看了关于明朝那些事的三杨，杨溥的经历应该比这个厉害吧，可是外国人看不懂，就像外国人不懂中国为什么有反分裂国家法，经历了鸦片战争，八国联军，抗日战争等等，其实跟外国对于黑人的权益的问题，因为有南北战争，所以极度重视这个问题，相应的中国也有自己的历史，请理解。</p>
-<p>简而言之我对寄生虫的评分大概 5~6 分吧。</p>

+          <p>寄生虫这部电影在获得奥斯卡之前就有关注了，豆瓣评分很高，一开始看到这个片名以为是像《铁线虫入侵》那种灾难片，后来看到男主，宋康昊，也是老面孔了，从高中时候在学校操场组织看的《汉江怪物》，有点二的感觉，后来在大学寝室电脑上重新看的时候，室友跟我说是韩国国宝级演员，真人不可貌相，感觉是个呆子的形象。</p>
+<p>但是你说这不是个灾难片，而是个反映社会问题的，就业比较容易往这个方向猜，只是剧情会是怎么样的，一时也没啥头绪，后来不知道哪里看了下一个剧情透露，是一个穷人给富人做家教，然后把自己一家都带进富人家，如果是这样的话可能会把这个怎么带进去作为一个主线，不过事实告诉我，这没那么重要，从第一步朋友的介绍，就显得无比顺利，要去当家教了，作为一个穷成这样的人，瞬间转变成一个衣着得体，言行举止都没让富人家看出破绽的延世大学学生，这真的挺难让人理解，所谓江山易改，本性难移，还有就是这人也正好有那么好能力去辅导，并且诡异的是，多惠也是瞬间就喜欢上了男主，多惠跟将男主介绍给她做家教，也就是多惠原来的家教敏赫，应该也有不少的相处时间，这变了有点大了吧，当然这里也可能因为时长需要，如果说这一点是因为时长，那可能我所有的槽点都是因为这个吧，因为我理解的应该是把家里的人如何一步步地带进富人家，这应该是整个剧情的一个需要更多铺垫去克服这个矛盾点，有时候也想过如果我去当导演，是能拍出个啥，没这个机会，可能有也会是很扯淡的，当然这也不能阻拦我谈谈对这个点的一些看法，毕竟评价一台电冰箱不是说我必须得自己会制冷对吧，这大概是我觉得这个电影的第一个槽点，接下去接二连三的，就是我说的这个最核心的矛盾点，不知道谁说过，这种影视剧应该是源自于生活又高于生活，越是好的作品，越要接近生活，这样子才更能有感同身受。</p>
+<p>接下去的点是金基宇介绍金基婷去给多颂当美术家教，这一步又是我理解的败笔吧，就怎么说呢，没什么铺垫，突然从一个社会底层的穷姑娘，转变成一个气场爆表，把富人家太太唬得一愣一愣的，如果说富太太是比较简单无脑的，那富人自己应该是比较有见识而且是做 IT 的，给自己儿子女儿做家教的，查查底细也很正常吧，但是啥都没有，然后呢，她又开始耍司机的心机了，真的是莫名其妙了，司机真的很惨，窈窕淑女君子好逑，而且这个操作也让我摸不着头脑，这是多腹黑并且有经验才会这么操作，脱内裤真的是让我看得一愣愣的，更看得我一愣一愣的，富人竟然也完全按着这个思路去想了，完全没有别的可能呢，甚至可以去查下行车记录仪或者怎样的，或者有没有毛发体液啥的去检验下，毕竟金基婷也乘坐过这辆车，但是最最让我不懂的还是脱内裤这个操作，究竟是什么样的人才会的呢，值得思考。</p>
+<p>金基泽和忠淑的点也是比较奇怪，首先是金基泽，引起最后那个杀人事件的一个由头，大部分观点都是人为朴社长在之前跟老婆啪啪啪的时候说金基泽的身上有股乘地铁的人的味道，简而言之就是穷人的味道，还有去雯光丈夫身下拿钥匙是对金基泽和雯光丈夫身上的味道的鄙夷，可是这个原因真的站不住脚，即使是同样经济水平，如果身上有比较重的异味，背后讨论下，或者闻到了比较重的味道，有不适的表情和动作很正常吧，像雯光丈夫，在地下室里呆了那么久，身上有异味并且比较重太正常了，就跟在厕所呆久了不会觉得味道大，但是从没味道的地方一进有点味道的厕所就会觉得异样，略尴尬的理由；再说忠淑呢，感觉是太厉害了，能胜任这么一家有钱人的各种挑剔的饮食口味要求的保姆职位，也是让人看懵逼了，看到了不禁想到一个问题，这家人开头是那么地穷，不堪，突然转变成这么地像骗子家族，如果有这么好的骗人能力，应该不会到这种地步吧，如果真的是那么穷，没能力，没志气，又怎么会突然变成这么厉害呢，一家人各司其职，把富人家唬得团团转，而这个前提是，这些人的确能胜任这四个位置，这就是我非常不能理解的点。</p>
+<p>然后说回这个标题，寄生虫，不知道是不是翻译过来不准确，如果真的是叫寄生虫的话，这个寄生虫智商未免也太低了，没有像新冠那样机制，致死率低一点，传染能力强一点，潜伏期也能传染，这个寄生虫第一次受到免疫系统的攻击就自爆了；还有呢，作为一个社会比较低层的打工者，乡下人，对这个审题也是不太审的清，是指这一家人是社会的寄生虫，不思进取，并且死的应该，富人是傻白甜，又有钱又善良，这是给有钱人洗地了还是啥，这个奥斯卡真不知道是怎么得的，总觉得奥斯卡，甚至低一点，豆瓣，得奖的，评分高的都是被一群“精英党”把持的，有黑人主角的，得分高；有同性恋的，得分高；结局惨的，得分高；看不懂的，得分高；就像肖申克的救赎，真不知道是哪里好了，最近看了关于明朝那些事的三杨，杨溥的经历应该比这个厉害吧，可是外国人看不懂，就像外国人不懂中国为什么有反分裂国家法，经历了鸦片战争，八国联军，抗日战争等等，其实跟外国对于黑人的权益的问题，因为有南北战争，所以极度重视这个问题，相应的中国也有自己的历史，请理解。</p>
+<p>简而言之我对寄生虫的评分大概 5~6 分吧。</p>

-<p>粗略看下，quicklist 里有 head，tail, quicklistNode里有 prev，next 指针，是不是有链表的基本轮廓了，那么为啥这玩意要称为快表呢，快在哪，关键就在这个<code>unsigned char *zl;</code>zl 是不是前面又看到过，就是 ziplist ，这是什么鬼，链表里用压缩表，这不套娃么，先别急，回顾下前面说的 ziplist，ziplist 有哪些特点，内存利用率高，可以从表头快速定位到尾节点，节点可以从后往前找，但是有个缺点，就是从中间插入的效率比较低，需要整体往后移，这个其实是普通数组的优化版，但还是有数组的一些劣势，所以要真的快，是不是可以将链表跟数组真的结合起来。</p>
-<h2 id="ziplist"><a href="#ziplist" class="headerlink" title="ziplist"></a>ziplist</h2><p>这里有两个 redis 的配置参数，<code>list-max-ziplist-size</code> 和 <code>list-compress-depth</code>，先来说第一个，既然快表是将链表跟压缩表数组结合起来使用，那么具体怎么用呢，比如我有一个 10 个元素的 list，那具体怎么放，每个 quicklistNode 里放多大的 ziplist，假如每个快表节点的 ziplist 只放一个元素，那么其实这就退化成了一个链表，如果 10 个元素放在一个 quicklistNode 的 ziplist 里，那就退化成了一个 ziplist，所以有了这个 <code>list-max-ziplist-size</code>,而且它还比较牛，能取正负值，当是正值时，对应的就是每个 quicklistNode 的 ziplist 中的元素个数，比如配置了 <code>list-max-ziplist-size = 5</code>，那么我刚才的 10 个元素的 list 就是一个两个 quicklistNode 组成的快表，每个 quicklistNode 中的 ziplist 包含了五个元素，当 <code>list-max-ziplist-size</code>取负值的时候，它限制了 ziplist 的字节数</p>

-<h2 id="压缩"><a href="#压缩" class="headerlink" title="压缩"></a>压缩</h2><p><code>list-compress-depth</code>这个参数呢是用来配置压缩的，等等压缩是为啥，不是里面已经是压缩表了么，大牛们就是为了性能殚精竭虑，这里考虑到的是一个场景，一般状况下，list 都是两端的访问频率比较高，那么是不是可以对中间的数据进行压缩，那么这个参数就是用来表示</p>

-<p>前面第一步先根据插入的是头还是尾选择不同的 push 函数，quicklistPushHead 或者 quicklistPushTail，举例分析下从头插入的 quicklistPushHead，先判断当前的 quicklistNode 节点还能不能允许再往 ziplist 里添加元素，如果可以就添加，如果不允许就新建一个 quicklistNode，然后调用 _quicklistInsertNodeBefore 将节点插进去，具体插入quicklist节点的操作类似链表的插入。</p>

-<p>主体结构就是这个 redisObject，</p>
+          <p>这应该是 redis 系列的最后一篇了，讲下快表，其实最前面讲的链表在早先的 redis 版本中也作为 list 的数据结构使用过，但是单纯的链表的缺陷之前也说了，插入便利，但是空间利用率低，并且不能进行二分查找等，检索效率低，ziplist 压缩表的产生也是同理，希望获得更好的性能，包括存储空间和访问性能等，原来我也不懂这个快表要怎么快，然后明白了一个道理，其实并没有什么银弹，只是大牛们会在适合的时候使用最适合的数据结构来实现性能的最大化，这里面有一招就是不同数据结构的组合调整，比如 Java 中的 HashMap，在链表节点数大于 8 时会转变成红黑树，以此提高访问效率，不费话了，回到快表，quicklist，这个数据结构主要使用在 list 类型中，如果我说其实这个 quicklist 就是个链表，可能大家不太会相信，但是事实上的确可以认为 quicklist 是个双向链表，看下代码</p>

+<p>粗略看下，quicklist 里有 head，tail, quicklistNode里有 prev，next 指针，是不是有链表的基本轮廓了，那么为啥这玩意要称为快表呢，快在哪，关键就在这个<code>unsigned char *zl;</code>zl 是不是前面又看到过，就是 ziplist ，这是什么鬼，链表里用压缩表，这不套娃么，先别急，回顾下前面说的 ziplist，ziplist 有哪些特点，内存利用率高，可以从表头快速定位到尾节点，节点可以从后往前找，但是有个缺点，就是从中间插入的效率比较低，需要整体往后移，这个其实是普通数组的优化版，但还是有数组的一些劣势，所以要真的快，是不是可以将链表跟数组真的结合起来。</p>
+<h2 id="ziplist"><a href="#ziplist" class="headerlink" title="ziplist"></a>ziplist</h2><p>这里有两个 redis 的配置参数，<code>list-max-ziplist-size</code> 和 <code>list-compress-depth</code>，先来说第一个，既然快表是将链表跟压缩表数组结合起来使用，那么具体怎么用呢，比如我有一个 10 个元素的 list，那具体怎么放，每个 quicklistNode 里放多大的 ziplist，假如每个快表节点的 ziplist 只放一个元素，那么其实这就退化成了一个链表，如果 10 个元素放在一个 quicklistNode 的 ziplist 里，那就退化成了一个 ziplist，所以有了这个 <code>list-max-ziplist-size</code>,而且它还比较牛，能取正负值，当是正值时，对应的就是每个 quicklistNode 的 ziplist 中的元素个数，比如配置了 <code>list-max-ziplist-size = 5</code>，那么我刚才的 10 个元素的 list 就是一个两个 quicklistNode 组成的快表，每个 quicklistNode 中的 ziplist 包含了五个元素，当 <code>list-max-ziplist-size</code>取负值的时候，它限制了 ziplist 的字节数</p>

-          <p>在 redis 中还有一类表型数据结构叫压缩表，ziplist，它的目的是替代链表，链表是个很容易理解的数据结构，双向链表有前后指针，有带头结点的有的不带，但是链表有个比较大的问题是相对于普通的数组，它的内存不连续，碎片化的存储，内存利用效率不高，而且指针寻址相对于直接使用偏移量的话，也有一定的效率劣势，当然这不是主要的原因，ziplist 设计的主要目的是让链表的内存使用更高效</p>
-<blockquote>
-<p>The ziplist is a specially encoded dually linked list that is designed to be very memory efficient.<br>这是摘自 redis 源码中ziplist.c 文件的注释，也说明了原因，它的大概结构是这样子</p>
-</blockquote>

-<p>其中<br><code>&lt;zlbytes&gt;</code>表示 ziplist 占用的字节总数，类型是uint32_t，32 位的无符号整型，当然表示的字节数也包含自己本身占用的 4 个<br><code>&lt;zltail&gt;</code> 类型也是是uint32_t，表示ziplist表中最后一项（entry）在ziplist中的偏移字节数。<code>&lt;zltail&gt;</code>的存在，使得我们可以很方便地找到最后一项（不用遍历整个ziplist），从而可以在ziplist尾端快速地执行push或pop操作。<br><code>&lt;uint16_t zllen&gt;</code> 表示ziplist 中的数据项个数，因为是 16 位，所以当数量超过所能表示的最大的数量，它的 16 位全会置为 1，但是真实的数量需要遍历整个 ziplist 才能知道<br><code>&lt;entry&gt;</code>是具体的数据项，后面解释<br><code>&lt;zlend&gt;</code> ziplist 的最后一个字节，固定是255。<br>再看一下<code>&lt;entry&gt;</code>中的具体结构，</p>

-<p>首先这个<code>&lt;prevlen&gt;</code>有两种情况，一种是前面的元素的长度，如果是小于等于 253的时候就用一个uint8_t 来表示前一元素的长度，如果大于的话他将占用五个字节，第一个字节是 254，即表示这个字节已经表示不下了，需要后面的四个字节帮忙表示<br><code>&lt;encoding&gt;</code>这个就比较复杂，把源码的注释放下面先看下</p>

-<p>首先如果 encoding 的前两位是 00 的话代表这个元素是个 6 位的字符串，即直接将数据保存在 encoding 中，不消耗额外的<code>&lt;entry-data&gt;</code>，如果前两位是 01 的话表示是个 14 位的字符串，如果是 10 的话表示encoding 块之后的四个字节是存放字符串类型的数据，encoding 的剩余 6 位置 0。<br>如果 encoding 的前两位是 11 的话表示这是个整型，具体的如果后两位是00的话，表示后面是个2字节的 int16_t 类型，如果是01的话，后面是个4字节的int32_t,如果是10的话后面是8字节的int64_t,如果是 11 的话后面是 3 字节的有符号整型，这些都要最后 4 位都是 0 的情况噢<br>剩下当是<code>11111110</code>时，则表示是一个1 字节的有符号数，如果是 <code>1111xxxx</code>，其中<code>xxxx</code>在0000 到 1101 表示实际的 1 到 13，为啥呢，因为 0000 前面已经用过了，而 1110 跟 1111 也都有用了。<br>看个具体的例子(上下有点对不齐，将就看)</p>

-<p>第一部分代表整个 ziplist 有 15 个字节，zlbytes 自己占了 4 个 zltail 表示最后一个元素的偏移量，第 13 个字节起，zllen 表示有 2 个元素，第一个元素是<code>00f3</code>,00表示前一个元素长度是 0，本来前面就没元素(不过不知道这个能不能优化这一字节)，然后是 f3，换成二进制就是11110011,对照上面的注释，是落在|1111xxxx|这个类型里，注意这个其实是用 0001 到 1101 也就是 1到 13 来表示 0到 12，所以 f3 应该就是 2，第一个元素是 2，第二个元素呢，02 代表前一个元素也就是刚才说的这个，占用 2 字节，f6 展开也是刚才的类型，实际是 5，ff 表示 ziplist 的结尾，所以这个 ziplist 里面是两个元素，2 跟 5</p>
+          <p>前面说了这么些数据结构，其实大家对于 redis 最初的印象应该就是个 key-value 的缓存，类似于 memcache，redis 其实也是个 key-value，key 还是一样的字符串，或者说就是用 redis 自己的动态字符串实现，但是 value 其实就是前面说的那些数据结构，差不多快说完了，还有个 quicklist 后面还有一篇，这里先介绍下 redis 对于这些不同类型的 value 是怎么实现的，首先看下 redisObject 的源码头文件</p>

-<p>一眼看，为啥整型还需要编码，然后 int8_t 怎么能存下大整形呢，带着这些疑问，我们一步步分析下去，这里的编码其实指的是这个整型集合里存的究竟是多大的整型，16 位，还是 32 位，还是 64 位，结构体下面的宏定义就是表示了 encoding 的可能取值，INTSET_ENC_INT16 表示每个元素用2个字节存储，INTSET_ENC_INT32 表示每个元素用4个字节存储，INTSET_ENC_INT64 表示每个元素用8个字节存储。因此，intset中存储的整数最多只能占用64bit。length 就是正常的表示集合中元素的数量。最奇怪的应该就是这个 contents 了，是个 int8_t 的数组，那放毛线数据啊，最小的都有 16 位，这里我在看代码和《redis 设计与实现》的时候也有点懵逼，后来查了下发现这是个比较取巧的用法，这里我用自己的理解表述一下，先看看 8，16，32，64 的关系，一眼看就知道都是 2 的 N 次，并且呈两倍关系，而且 8 位刚好一个字节，所以呢其实这里的contents 不是个常规意义上的 int8_t 类型的数组，而是个柔性数组。看下 wiki 的定义</p>
+          <p>在 redis 中还有一类表型数据结构叫压缩表，ziplist，它的目的是替代链表，链表是个很容易理解的数据结构，双向链表有前后指针，有带头结点的有的不带，但是链表有个比较大的问题是相对于普通的数组，它的内存不连续，碎片化的存储，内存利用效率不高，而且指针寻址相对于直接使用偏移量的话，也有一定的效率劣势，当然这不是主要的原因，ziplist 设计的主要目的是让链表的内存使用更高效</p>

-<p>在初始化这个 intset 的时候，这个contents数组是不占用空间的，后面的反正用到了申请，那么这里就有一个问题，给出了三种可能的 encoding 值，他们能随便换吗，显然不行，首先在 intset 中数据的存放是有序的，这个有部分原因是方便二分查找，然后存放数据其实随着数据的大小不同会有一个升级的过程，看下图<br><img data-src="https://i.loli.net/2020/01/10/qIc6HgP7wfCLipN.png" alt=""><br>新创建的intset只有一个header，总共8个字节。其中encoding = 2, length = 0, 类型都是uint32_t，各占 4 字节，添加15, 5两个元素之后，因为它们是比较小的整数，都能使用2个字节表示，所以encoding不变，值还是2，也就是默认的 <code>INTSET_ENC_INT16</code>，当添加32768的时候，它不再能用2个字节来表示了（2个字节能表达的数据范围是-215~215-1，而32768等于215，超出范围了），因此encoding必须升级到INTSET_ENC_INT32（值为4），即用4个字节表示一个元素。在添加每个元素的过程中，intset始终保持从小到大有序。与ziplist类似，intset也是按小端（little endian）模式存储的（参见维基百科词条<a href="https://en.wikipedia.org/wiki/Endianness" target="_blank" rel="noopener">Endianness</a>）。比如，在上图中intset添加完所有数据之后，表示encoding字段的4个字节应该解释成0x00000004，而第4个数据应该解释成0x00008000 = 32768</p>

-<p>当随机值跟0xFFFF进行与操作小于ZSKIPLIST_P * 0xFFFF时才会增大 level 的值，因此保持了一个相对递减的概率<br>可以简单分析下，当 random() 的值小于 0xFFFF 的 1/4,才会 level + 1，就意味着当有 1 - 1/4也就是3/4的概率是直接跳出，所以一层的概率是3/4,也就是 1-P，二层的概率是 P*(1-P),三层的概率是 P² * (1-P) 依次递推。</p>

+<p>一眼看，为啥整型还需要编码，然后 int8_t 怎么能存下大整形呢，带着这些疑问，我们一步步分析下去，这里的编码其实指的是这个整型集合里存的究竟是多大的整型，16 位，还是 32 位，还是 64 位，结构体下面的宏定义就是表示了 encoding 的可能取值，INTSET_ENC_INT16 表示每个元素用2个字节存储，INTSET_ENC_INT32 表示每个元素用4个字节存储，INTSET_ENC_INT64 表示每个元素用8个字节存储。因此，intset中存储的整数最多只能占用64bit。length 就是正常的表示集合中元素的数量。最奇怪的应该就是这个 contents 了，是个 int8_t 的数组，那放毛线数据啊，最小的都有 16 位，这里我在看代码和《redis 设计与实现》的时候也有点懵逼，后来查了下发现这是个比较取巧的用法，这里我用自己的理解表述一下，先看看 8，16，32，64 的关系，一眼看就知道都是 2 的 N 次，并且呈两倍关系，而且 8 位刚好一个字节，所以呢其实这里的contents 不是个常规意义上的 int8_t 类型的数组，而是个柔性数组。看下 wiki 的定义</p>

+<p>在初始化这个 intset 的时候，这个contents数组是不占用空间的，后面的反正用到了申请，那么这里就有一个问题，给出了三种可能的 encoding 值，他们能随便换吗，显然不行，首先在 intset 中数据的存放是有序的，这个有部分原因是方便二分查找，然后存放数据其实随着数据的大小不同会有一个升级的过程，看下图<br><img data-src="https://i.loli.net/2020/01/10/qIc6HgP7wfCLipN.png" alt=""><br>新创建的intset只有一个header，总共8个字节。其中encoding = 2, length = 0, 类型都是uint32_t，各占 4 字节，添加15, 5两个元素之后，因为它们是比较小的整数，都能使用2个字节表示，所以encoding不变，值还是2，也就是默认的 <code>INTSET_ENC_INT16</code>，当添加32768的时候，它不再能用2个字节来表示了（2个字节能表达的数据范围是-215~215-1，而32768等于215，超出范围了），因此encoding必须升级到INTSET_ENC_INT32（值为4），即用4个字节表示一个元素。在添加每个元素的过程中，intset始终保持从小到大有序。与ziplist类似，intset也是按小端（little endian）模式存储的（参见维基百科词条<a href="https://en.wikipedia.org/wiki/Endianness" target="_blank" rel="noopener">Endianness</a>）。比如，在上图中intset添加完所有数据之后，表示encoding字段的4个字节应该解释成0x00000004，而第4个数据应该解释成0x00008000 = 32768</p>

-<p>这里引用了 redis 在 github 上最早的 2.2 版本的代码，代码路径是<code>https://github.com/antirez/redis/blob/2.2/src/sds.h</code>,可以看到这个结构体里只有仨元素，两个 int 型和一个 char 型数组，两个 int 型其实就是我说的优化，因为 C 语言本身的字符串数组，有两个问题，一个是要知道它实际已被占用的长度，需要去遍历这个数组，第二个就是比较容易踩坑的是遍历的时候要注意它有个以<code>\0</code>作为结尾的特点；通过上面的两个 int 型参数，一个是知道字符串目前的长度，一个是知道字符串还剩余多少位空间，这样子坐着两个操作从 <code>O(N)</code>简化到了<code>O(1)</code>了，还有第二个 free 还有个比较重要的作用就是能防止 C 字符串的溢出问题，在存储之前可以先判断 free 长度，如果长度不够就先扩容了，先介绍到这，这个系列可以写蛮多的，慢慢介绍吧</p>

-<p>看了下这个 2.2 版本的代码跟最新版的其实也差的不是很多，所以还是照旧用老代码，可以看到上面四个结构体中，其实只有三个是存储数据用的，dictType 是用来放操作函数的，那么三个存放数据的结构体分别是干嘛的，这时候感觉需要一个图来说明比较好，稍等，我去画个图~<br><img data-src="https://i.loli.net/2019/12/29/UL4AR1HSEKOh9Qm.png" alt=""><br>这个图看着应该比较清楚这些都是用来干嘛的了，dict 是我们的主体结构，它有一个指向 dictType 的指针，这里面包含了字典的操作函数，然后是一个私有数据指针，接下来是一个 dictht 的数组，包含两个dictht，这个就是用来存数据的了，然后是 rehashidx 表示重哈希的状态，当是-1 的时候表示当前没有重哈希，iterators 表示正在遍历的迭代器的数量。<br>首先说说为啥需要有两个 dictht，这是因为字典 dict 这个数据结构随着数据量的增减，会需要在中途做扩容或者缩容操作，如果只有一个的话，对它进行扩容缩容时会影响正常的访问和修改操作，或者说保证正常查询，修改的正确性会比较复杂，并且因为需要高效利用空间，不能一下子申请一个非常大的空间来存很少的数据。当 dict 中 dictht 中的数据量超过 size 的时候负载就超过了 1，就需要进行扩容，这里的其实跟 Java 中的 HashMap 比较类似，超过一定的负载之后进行扩容。这里为啥 size 会超过 1 呢，可能有部分不了解这类结构的同学会比较奇怪，其实就是上图中画的，在数据结构中对于散列的冲突有几类解决方法，比如转换成链表，二次散列，找下个空槽等，这里就使用了链表法，或者说拉链法。当一个新元素通过 hashFunction 得出的 key 跟 sizemask 取模之后的值相同了，那就将其放在原来的节点之前，变成链表挂在数组 dictht.table下面，放在原有节点前是考虑到可能会优先访问。<br>忘了说明下 dictht 跟 dictEntry 的关系了，dictht 就是个哈希表，它里面是个dictEntry 的二维数组，而 dictEntry 是个包含了 key-value 结构之外还有一个 next 指针，因此可以将哈希冲突的以链表的形式保存下来。<br>在重点说下重哈希，可能同样写 Java 的同学对这个比较有感觉，跟 HashMap 一样，会以 2 的 N 次方进行扩容，那么扩容的方法就会比较简单，每个键重哈希要不就在原来这个槽，要不就在原来的槽加原 dictht.size 的位置；然后是重头戏，具体是怎么做扩容呢，其实这里就把第二个 ht 用上了，其实这两个hashtable 的具体作用有点类似于 jvm 中的两个 survival 区，但是又不全一样，因为 redis 在扩容的时候是采用的渐进式地重哈希，什么叫渐进式的呢，就是它不是像 jvm 那种标记复制的模式直接将一个 eden 区和原来的 survival 区存活的对象复制到另一个 survival 区，而是在每一次添加，删除，查找或者更新操作时，都会额外的帮忙搬运一部分的原 dictht 中的数据，这里会根据 rehashidx 的值来判断，如果是-1 表示并没有在重哈希中，如果是 0 表示开始重哈希了，然后rehashidx 还会随着每次的帮忙搬运往上加，但全部被搬运完成后 rehashidx 又变回了-1，又可以扯到Java 中的 Concurrent HashMap, 他在扩容的时候也使用了类似的操作。</p>
+          <h2 id="跳表-skiplist"><a href="#跳表-skiplist" class="headerlink" title="跳表 skiplist"></a>跳表 skiplist</h2><p>跳表是个在我们日常的代码中不太常用到的数据结构，相对来讲就没有像数组，链表，字典，散列，树等结构那么熟悉，所以就从头开始分析下，首先是链表，跳表跟链表都有个表字（太硬扯了我🤦‍♀️），注意这是个有序链表<br><img data-src="https://i.loli.net/2020/01/03/Og9i3pCIfxrMhja.png" alt=""><br>如上图，在这个链表里如果我要找到 23，是不是我需要从3，5，9开始一直往后找直到找到 23，也就是说时间复杂度是 O(N),N 的一次幂复杂度，那么我们来看看第二个<br><img data-src="https://i.loli.net/2020/01/03/81P2baupiedOmNf.png" alt=""><br>这个结构跟原先有点不一样，它给链表中偶数位的节点又加了一个指针把它们链接起来，这样子当我们要寻找 23 的时候就可以从原来的一个个往下找变成跳着找，先找到 5，然后是 10，接着是 19，然后是 28，这时候发现 28 比 23 大了，那我在退回到 19，然后从下一层原来的链表往前找，<br><img data-src="https://i.loli.net/2020/01/03/NBguAphilKjs2MO.png" alt=""><br>这里毛估估是不是前面的节点我就少找了一半,有那么点二分法的意思。<br>前面的其实是跳表的引子，真正的跳表其实不是这样，因为上面的其实有个比较大的问题，就是插入一个元素后需要调整每个元素的指针，在 redis 中的跳表其实是做了个随机层数的优化，因为沿着前面的例子，其实当数据量很大的时候，是不是层数越多，其查询效率越高，但是随着层数变多，要保持这种严格的层数规则其实也会增大处理复杂度，所以 redis 插入每个元素的时候都是使用随机的方式，看一眼代码</p>

+<p>忘了说了，redis 是把 skiplist 跳表用在 zset 里，zset 是个有序的集合，可以看到 zskiplist 就是个跳表的结构，里面用 header 保存跳表的表头，tail 保存表尾，还有长度和最大层级，具体的跳表节点元素使用 zskiplistNode 表示，里面包含了 sds 类型的元素值，double 类型的分值，用来排序，一个 backward 后向指针和一个 zskiplistLevel 数组，每个 level 包含了一个前向指针，和一个 span，span 表示的是跳表前向指针的跨度，这里再补充一点，前面说了为了灵活这个跳表的新增修改，redis 使用了随机层高的方式插入新节点，但是如果所有节点都随机到很高的层级或者所有都很低的话，跳表的效率优势就会减小，所以 redis 使用了个小技巧，贴下代码</p>

+<p>当随机值跟0xFFFF进行与操作小于ZSKIPLIST_P * 0xFFFF时才会增大 level 的值，因此保持了一个相对递减的概率<br>可以简单分析下，当 random() 的值小于 0xFFFF 的 1/4,才会 level + 1，就意味着当有 1 - 1/4也就是3/4的概率是直接跳出，所以一层的概率是3/4,也就是 1-P，二层的概率是 P*(1-P),三层的概率是 P² * (1-P) 依次递推。</p>

+          <p>redis是现在服务端很常用的缓存中间件，其实原来还有<code>memcache</code>之类的竞品，但是现在貌似 redis 快一统江湖，这里当然不是在吹，只是个人角度的一个感觉，不权威只是主观感觉。<br>redis 主要有五种数据结构，<code>Strings</code>，<code>Lists</code>，<code>Sets</code>，<code>Hashes</code>，<code>Sorted Sets</code>，这五种数据结构先简单介绍下，<code>Strings</code>类型的其实就是我们最常用的 key-value，实际开发中也会用的最多；<code>Lists</code>是列表，这个有些会用来做队列，因为 redis 目前常用的版本支持丰富的列表操作；还有是<code>Sets</code>集合，这个主要的特点就是集合中元素不重复，可以用在有这类需求的场景里；<code>Hashes</code>是叫散列，类似于 Python 中的字典结构；还有就是<code>Sorted Sets</code>这个是个有序集合；一眼看这些其实没啥特别的，除了最后这个有序集合，不过去了解背后的实现方式还是比较有意思的。</p>
+<h2 id="SDS-简单动态字符串"><a href="#SDS-简单动态字符串" class="headerlink" title="SDS 简单动态字符串"></a>SDS 简单动态字符串</h2><p>先从<code>Strings</code>开始说，了解过 C 语言的应该知道，C 语言中的字符串其实是个 <code>char[]</code> 字符数组，redis 也不例外，只是最开始的版本就对这个做了一丢丢的优化，而正是这一丢丢的优化，让这个 redis 的使用效率提升了数倍</p>

+<p>这里引用了 redis 在 github 上最早的 2.2 版本的代码，代码路径是<code>https://github.com/antirez/redis/blob/2.2/src/sds.h</code>,可以看到这个结构体里只有仨元素，两个 int 型和一个 char 型数组，两个 int 型其实就是我说的优化，因为 C 语言本身的字符串数组，有两个问题，一个是要知道它实际已被占用的长度，需要去遍历这个数组，第二个就是比较容易踩坑的是遍历的时候要注意它有个以<code>\0</code>作为结尾的特点；通过上面的两个 int 型参数，一个是知道字符串目前的长度，一个是知道字符串还剩余多少位空间，这样子坐着两个操作从 <code>O(N)</code>简化到了<code>O(1)</code>了，还有第二个 free 还有个比较重要的作用就是能防止 C 字符串的溢出问题，在存储之前可以先判断 free 长度，如果长度不够就先扩容了，先介绍到这，这个系列可以写蛮多的，慢慢介绍吧</p>
+<h2 id="链表"><a href="#链表" class="headerlink" title="链表"></a>链表</h2><p>链表是比较常见的数据结构了，但是因为 redis 是用 C 写的，所以在不依赖第三方库的情况下只能自己写一个了，redis 的链表是个有头的链表，而且是无环的，具体的结构我也找了 github 上最早版本的代码</p>

+<p>代码地址是这个<code>https://github.com/antirez/redis/blob/2.2/src/adlist.h</code><br>可以看下节点是由listNode承载的，包括值和一个指向前节点跟一个指向后一节点的两个指针，然后值是 void 指针类型，所以可以承载不同类型的值<br>然后是 list结构用来承载一个链表，包含了表头，和表尾，复制函数，释放函数和比较函数，还有链表长度，因为包含了前两个节点，找到表尾节点跟表头都是 <code>O(1)</code>的时间复杂度，还有节点数量，其实这个跟 SDS 是同一个做法，就是空间换时间，这也是写代码里比较常见的做法，以此让一些高频的操作提速。</p>
+<h2 id="字典"><a href="#字典" class="headerlink" title="字典"></a>字典</h2><p>字典也是个常用的数据结构，其实只是叫法不同，数据结构中叫 hash 散列，Java 中叫 Map，PHP 中是数组 array，Python 中也叫字典 dict，因为纯 C 语言本身不带这些数据结构，所以这也是个痛并快乐着的过程，享受 C 语言的高性能的同时也要接受它只提供了语言的基本功能的现实，各种轮子都需要自己造，redis 同样实现了自己的字典<br>下面来看看代码</p>

+<p>看了下这个 2.2 版本的代码跟最新版的其实也差的不是很多，所以还是照旧用老代码，可以看到上面四个结构体中，其实只有三个是存储数据用的，dictType 是用来放操作函数的，那么三个存放数据的结构体分别是干嘛的，这时候感觉需要一个图来说明比较好，稍等，我去画个图~<br><img data-src="https://i.loli.net/2019/12/29/UL4AR1HSEKOh9Qm.png" alt=""><br>这个图看着应该比较清楚这些都是用来干嘛的了，dict 是我们的主体结构，它有一个指向 dictType 的指针，这里面包含了字典的操作函数，然后是一个私有数据指针，接下来是一个 dictht 的数组，包含两个dictht，这个就是用来存数据的了，然后是 rehashidx 表示重哈希的状态，当是-1 的时候表示当前没有重哈希，iterators 表示正在遍历的迭代器的数量。<br>首先说说为啥需要有两个 dictht，这是因为字典 dict 这个数据结构随着数据量的增减，会需要在中途做扩容或者缩容操作，如果只有一个的话，对它进行扩容缩容时会影响正常的访问和修改操作，或者说保证正常查询，修改的正确性会比较复杂，并且因为需要高效利用空间，不能一下子申请一个非常大的空间来存很少的数据。当 dict 中 dictht 中的数据量超过 size 的时候负载就超过了 1，就需要进行扩容，这里的其实跟 Java 中的 HashMap 比较类似，超过一定的负载之后进行扩容。这里为啥 size 会超过 1 呢，可能有部分不了解这类结构的同学会比较奇怪，其实就是上图中画的，在数据结构中对于散列的冲突有几类解决方法，比如转换成链表，二次散列，找下个空槽等，这里就使用了链表法，或者说拉链法。当一个新元素通过 hashFunction 得出的 key 跟 sizemask 取模之后的值相同了，那就将其放在原来的节点之前，变成链表挂在数组 dictht.table下面，放在原有节点前是考虑到可能会优先访问。<br>忘了说明下 dictht 跟 dictEntry 的关系了，dictht 就是个哈希表，它里面是个dictEntry 的二维数组，而 dictEntry 是个包含了 key-value 结构之外还有一个 next 指针，因此可以将哈希冲突的以链表的形式保存下来。<br>在重点说下重哈希，可能同样写 Java 的同学对这个比较有感觉，跟 HashMap 一样，会以 2 的 N 次方进行扩容，那么扩容的方法就会比较简单，每个键重哈希要不就在原来这个槽，要不就在原来的槽加原 dictht.size 的位置；然后是重头戏，具体是怎么做扩容呢，其实这里就把第二个 ht 用上了，其实这两个hashtable 的具体作用有点类似于 jvm 中的两个 survival 区，但是又不全一样，因为 redis 在扩容的时候是采用的渐进式地重哈希，什么叫渐进式的呢，就是它不是像 jvm 那种标记复制的模式直接将一个 eden 区和原来的 survival 区存活的对象复制到另一个 survival 区，而是在每一次添加，删除，查找或者更新操作时，都会额外的帮忙搬运一部分的原 dictht 中的数据，这里会根据 rehashidx 的值来判断，如果是-1 表示并没有在重哈希中，如果是 0 表示开始重哈希了，然后rehashidx 还会随着每次的帮忙搬运往上加，但全部被搬运完成后 rehashidx 又变回了-1，又可以扯到Java 中的 Concurrent HashMap, 他在扩容的时候也使用了类似的操作。</p>

-<p>其实可以主要关注这个 <code>waitStatus</code> 因为这个是后面的节点给前面的节点设置的，等于-1 的时候代表后面有节点等待，需要去唤醒，<br>这里使用了一个变种的 CLH 队列实现，CLH 队列相关内容可以查看这篇 <a href="https://coderbee.net/index.php/concurrent/20131115/577" target="_blank" rel="noopener">自旋锁、排队自旋锁、MCS锁、CLH锁</a></p>

-          <p>目前公司要对一些新的产品功能做灰度测试，因为在后端业务代码层面添加判断比较麻烦，所以想在nginx上做点手脚，就想到了openresty<br>前后也踩了不少坑，这边先写一点</p>
-<p>首先是日志<br><code>error_log logs/error.log debug;</code><br>需要nginx开启日志的debug才能看到日志</p>
-<p>使用 <code>lua_code_cache off</code>即可, 另外注意只有使用 <code>content_by_lua_file</code> 才会生效</p>
-<figure class="highlight lua"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br></pre></td><td class="code"><pre><span class="line">http &#123;</span><br><span class="line">  lua_code_cache off;</span><br><span class="line">&#125;</span><br><span class="line"></span><br><span class="line">location ~* /(\d+-.*)/api/orgunits/load_all(.*) &#123;</span><br><span class="line">   default_type <span class="string">'application/json;charset=utf-8'</span>;</span><br><span class="line">   content_by_lua_file /data/projects/xxx/current/lua/controller/load_data.lua;</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>

-<p><a href="http://cyukang.com/2017/05/22/try-on-openresty.html" target="_blank" rel="noopener">使用总结</a></p>
-<p>后续：</p>
-<ol>
-<li>一开始在本地环境的时候使用content_by_lua_file只关注了头，后来发到测试环境发现请求内容都没代理转发到后端服务上<br>网上查了下发现content_by_lua_file是将请求的所有内容包括response都用这里面的lua脚本生成了，content这个词就表示是请求内容<br>后来改成了access_by_lua_file就正常了，只是要去获取请求内容和修改响应头，并不是要完整的接管请求</li>
-</ol>
-<ol start="2">
-<li><p>后来又碰到了一个坑是nginx有个client_body_buffer_size的配置参数，nginx在32位和64位系统里有8K和16K两个默认值，当请求内容大于这两个值的时候，会把请求内容放到临时文件里，这个时候openresty里的ngx.req.get_post_args()就会报“failed to get post args: requesty body in temp file not supported”这个错误，将client_body_buffer_size这个参数配置调大一点就好了</p>
-</li>
-<li><p>还有就是lua的异常捕获，网上看一般是用pcall和xpcall来进行保护调用，因为问题主要出在cjson的decode，这里有两个解决方案，一个就是将cjson.decode使用pcall封装，</p>
- <figure class="highlight lua"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">local</span> decode = <span class="built_in">require</span>(<span class="string">"cjson"</span>).decode</span><br><span class="line"></span><br><span class="line"><span class="function"><span class="keyword">function</span> <span class="title">json_decode</span><span class="params">( str )</span></span></span><br><span class="line">    <span class="keyword">local</span> ok, t = <span class="built_in">pcall</span>(decode, str)</span><br><span class="line">    <span class="keyword">if</span> <span class="keyword">not</span> ok <span class="keyword">then</span></span><br><span class="line">      <span class="keyword">return</span> <span class="literal">nil</span></span><br><span class="line">    <span class="keyword">end</span></span><br><span class="line"></span><br><span class="line">    <span class="keyword">return</span> t</span><br><span class="line"><span class="keyword">end</span></span><br></pre></td></tr></table></figure>
-<p> 这个是使用了pcall，称为保护调用，会在内部错误后返回两个参数，第一个是false，第二个是错误信息<br> 还有一种是使用cjson.safe包</p>
- <figure class="highlight lua"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">local</span> json = <span class="built_in">require</span>(<span class="string">"cjson.safe"</span>)</span><br><span class="line"><span class="keyword">local</span> str = <span class="string">[[ &#123;"key:"value"&#125; ]]</span></span><br><span class="line"></span><br><span class="line"><span class="keyword">local</span> t = json.decode(str)</span><br><span class="line"><span class="keyword">if</span> t <span class="keyword">then</span></span><br><span class="line">    ngx.say(<span class="string">" --&gt; "</span>, <span class="built_in">type</span>(t))</span><br><span class="line"><span class="keyword">end</span></span><br></pre></td></tr></table></figure>
-<p> cjson.safe包会在解析失败的时候返回nil</p>
-</li>
-<li><p>还有一个是redis链接时如果host使用的是域名的话会提示“failed to connect: no resolver defined to resolve “redis.xxxxxx.com””，这里需要使用nginx的resolver指令，<br><code>resolver 8.8.8.8 valid=3600s;</code></p>
-</li>
-<li><p>还有一点补充下<br>就是业务在使用redis的时候使用了db的特性，所以在lua访问redis的时候也需要执行db，这里lua的redis库也支持了这个特性，可以使用instance:select(config:get(‘db’))来切换db</p>
-</li>
-<li><p>性能优化tips<br><a href="https://juejin.im/entry/5b0e8fcef265da09210072a3#openresty" target="_blank" rel="noopener">建议是尽量少使用阶段钩子，例如content_by_lua_file，*_by_lua</a></p>

-<h2 id="简单过程"><a href="#简单过程" class="headerlink" title="简单过程"></a>简单过程</h2><ul>
-<li>第一个坑<br>在刚开始是按照官网的指南，用maven构建，因为GFW的原因，导致反复失败等待，也就是这个<a href="https://cwiki.apache.org/confluence/display/AMBARI/Installation+Guide+for+Ambari+2.5.0" target="_blank" rel="noopener">guide</a>，因为对maven不熟悉导致有些按图索骥，浪费了很多时间，之后才知道可以直接加repo用yum安装，然而用yum安装马上就出现了第二个坑。</li>
-<li>第二个坑<br>因为在线的repo还是因为网络原因很慢很慢，用proxychains勉强把ambari-server本身安装好了，<a href="http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.5.0.3/ambari.repo" target="_blank" rel="noopener">ambari.repo</a>将这个放进<code>/etc/yum.repos.d/</code>路径下，然后<code>yum update &amp;&amp; yum install ambari-server</code>安装即可，如果有条件就用proxychains走下代理。</li>
-<li>第三步<br>安装好ambari-server后先执行<code>ambari-server setup</code>做一些初始化设置，其中包含了JDK路径的设置，数据库设置，设置好就OK了，然后执行<code>ambari-server start</code>启动服务，这里有个小插曲，因为<code>ambari-server</code>涉及到这么多服务，所以管理控制监控之类的模块是必不可少的，这部分可以在<code>ambari-server</code>的web ui界面安装，也可以命令行提前安装，这部分被称为<code>HDF Management Pack</code>，运行```ambari-server install-mpack \</li>
-<li>-mpack=<a href="http://public-repo-1.hortonworks.com/HDF/centos7/2.x/updates/2.1.4.0/tars/hdf_ambari_mp/hdf-ambari-mpack-2.1.4.0-5.tar.gz" target="_blank" rel="noopener">http://public-repo-1.hortonworks.com/HDF/centos7/2.x/updates/2.1.4.0/tars/hdf_ambari_mp/hdf-ambari-mpack-2.1.4.0-5.tar.gz</a> \</li>

+          <p>目前公司要对一些新的产品功能做灰度测试，因为在后端业务代码层面添加判断比较麻烦，所以想在nginx上做点手脚，就想到了openresty<br>前后也踩了不少坑，这边先写一点</p>
+<p>首先是日志<br><code>error_log logs/error.log debug;</code><br>需要nginx开启日志的debug才能看到日志</p>
+<p>使用 <code>lua_code_cache off</code>即可, 另外注意只有使用 <code>content_by_lua_file</code> 才会生效</p>

+<p><a href="http://cyukang.com/2017/05/22/try-on-openresty.html" target="_blank" rel="noopener">使用总结</a></p>
+<p>后续：</p>
+<ol>
+<li>一开始在本地环境的时候使用content_by_lua_file只关注了头，后来发到测试环境发现请求内容都没代理转发到后端服务上<br>网上查了下发现content_by_lua_file是将请求的所有内容包括response都用这里面的lua脚本生成了，content这个词就表示是请求内容<br>后来改成了access_by_lua_file就正常了，只是要去获取请求内容和修改响应头，并不是要完整的接管请求</li>
+</ol>
+<ol start="2">
+<li><p>后来又碰到了一个坑是nginx有个client_body_buffer_size的配置参数，nginx在32位和64位系统里有8K和16K两个默认值，当请求内容大于这两个值的时候，会把请求内容放到临时文件里，这个时候openresty里的ngx.req.get_post_args()就会报“failed to get post args: requesty body in temp file not supported”这个错误，将client_body_buffer_size这个参数配置调大一点就好了</p>
+</li>
+<li><p>还有就是lua的异常捕获，网上看一般是用pcall和xpcall来进行保护调用，因为问题主要出在cjson的decode，这里有两个解决方案，一个就是将cjson.decode使用pcall封装，</p>
+ <figure class="highlight lua"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">local</span> decode = <span class="built_in">require</span>(<span class="string">"cjson"</span>).decode</span><br><span class="line"></span><br><span class="line"><span class="function"><span class="keyword">function</span> <span class="title">json_decode</span><span class="params">( str )</span></span></span><br><span class="line">    <span class="keyword">local</span> ok, t = <span class="built_in">pcall</span>(decode, str)</span><br><span class="line">    <span class="keyword">if</span> <span class="keyword">not</span> ok <span class="keyword">then</span></span><br><span class="line">      <span class="keyword">return</span> <span class="literal">nil</span></span><br><span class="line">    <span class="keyword">end</span></span><br><span class="line"></span><br><span class="line">    <span class="keyword">return</span> t</span><br><span class="line"><span class="keyword">end</span></span><br></pre></td></tr></table></figure>
+<p> 这个是使用了pcall，称为保护调用，会在内部错误后返回两个参数，第一个是false，第二个是错误信息<br> 还有一种是使用cjson.safe包</p>
+ <figure class="highlight lua"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">local</span> json = <span class="built_in">require</span>(<span class="string">"cjson.safe"</span>)</span><br><span class="line"><span class="keyword">local</span> str = <span class="string">[[ &#123;"key:"value"&#125; ]]</span></span><br><span class="line"></span><br><span class="line"><span class="keyword">local</span> t = json.decode(str)</span><br><span class="line"><span class="keyword">if</span> t <span class="keyword">then</span></span><br><span class="line">    ngx.say(<span class="string">" --&gt; "</span>, <span class="built_in">type</span>(t))</span><br><span class="line"><span class="keyword">end</span></span><br></pre></td></tr></table></figure>
+<p> cjson.safe包会在解析失败的时候返回nil</p>
+</li>
+<li><p>还有一个是redis链接时如果host使用的是域名的话会提示“failed to connect: no resolver defined to resolve “redis.xxxxxx.com””，这里需要使用nginx的resolver指令，<br><code>resolver 8.8.8.8 valid=3600s;</code></p>
+</li>
+<li><p>还有一点补充下<br>就是业务在使用redis的时候使用了db的特性，所以在lua访问redis的时候也需要执行db，这里lua的redis库也支持了这个特性，可以使用instance:select(config:get(‘db’))来切换db</p>
+</li>
+<li><p>性能优化tips<br><a href="https://juejin.im/entry/5b0e8fcef265da09210072a3#openresty" target="_blank" rel="noopener">建议是尽量少使用阶段钩子，例如content_by_lua_file，*_by_lua</a></p>

Well, these messages won&#39;t match any bindings and will be lost.</code><a href="http://www.rabbitmq.com/tutorials/tutorial-five-python.html" target="_blank" rel="noopener">对应链接</a>,而当使用空的exchange时，会保留消息，当出现消费者的时候就可以将收到之前生产者所推送的消息<a href="http://www.rabbitmq.com/tutorials/tutorial-two-python.html" target="_blank" rel="noopener">对应链接</a>,这里就是用了空的exchange。</p>
-<h3 id="集群搭建"><a href="#集群搭建" class="headerlink" title="集群搭建"></a>集群搭建</h3><p>集群搭建的时候有个erlang vm生成的random cookie，这个是用来做集群之间认证的，相同的cookie才能连接，但是如果通过vim打开复制后在其他几点新建文件写入会多一个换行，导致集群建立是报错，所以这里最好使用scp等传输命令直接传输cookie文件，同时要注意下cookie的文件权限。<br>另外在集群搭建的时候如果更改过hostname，那么要把rabbitmq的数据库删除，否则启动后会马上挂掉</p>

+<h2 id="简单过程"><a href="#简单过程" class="headerlink" title="简单过程"></a>简单过程</h2><ul>
+<li>第一个坑<br>在刚开始是按照官网的指南，用maven构建，因为GFW的原因，导致反复失败等待，也就是这个<a href="https://cwiki.apache.org/confluence/display/AMBARI/Installation+Guide+for+Ambari+2.5.0" target="_blank" rel="noopener">guide</a>，因为对maven不熟悉导致有些按图索骥，浪费了很多时间，之后才知道可以直接加repo用yum安装，然而用yum安装马上就出现了第二个坑。</li>
+<li>第二个坑<br>因为在线的repo还是因为网络原因很慢很慢，用proxychains勉强把ambari-server本身安装好了，<a href="http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.5.0.3/ambari.repo" target="_blank" rel="noopener">ambari.repo</a>将这个放进<code>/etc/yum.repos.d/</code>路径下，然后<code>yum update &amp;&amp; yum install ambari-server</code>安装即可，如果有条件就用proxychains走下代理。</li>
+<li>第三步<br>安装好ambari-server后先执行<code>ambari-server setup</code>做一些初始化设置，其中包含了JDK路径的设置，数据库设置，设置好就OK了，然后执行<code>ambari-server start</code>启动服务，这里有个小插曲，因为<code>ambari-server</code>涉及到这么多服务，所以管理控制监控之类的模块是必不可少的，这部分可以在<code>ambari-server</code>的web ui界面安装，也可以命令行提前安装，这部分被称为<code>HDF Management Pack</code>，运行```ambari-server install-mpack \</li>
+<li>-mpack=<a href="http://public-repo-1.hortonworks.com/HDF/centos7/2.x/updates/2.1.4.0/tars/hdf_ambari_mp/hdf-ambari-mpack-2.1.4.0-5.tar.gz" target="_blank" rel="noopener">http://public-repo-1.hortonworks.com/HDF/centos7/2.x/updates/2.1.4.0/tars/hdf_ambari_mp/hdf-ambari-mpack-2.1.4.0-5.tar.gz</a> \</li>
+<li>-purge \</li>
+<li>-verbose```<br>安装，当然这个压缩包可以下载之后指到本地路径安装，然后就可以重启<code>ambari-server</code></li>

+<p>Given a sorted array of integers, find the starting and ending position of a given target value.</p>
+<p>Your algorithm’s runtime complexity must be in the order of <em>O</em>(log <em>n</em>).</p>
+<p>If the target is not found in the array, return <code>[-1, -1]</code>.</p>
+<p>For example,<br>Given <code>[5, 7, 7, 8, 8, 10]</code> and target value 8,<br>return <code>[3, 4]</code>.</p>
+<h2 id="analysis"><a href="#analysis" class="headerlink" title="analysis"></a>analysis</h2><p>一开始就想到了二分查找，但是原来做二分查找的时候一般都是找到确定的那个数就完成了，<br>这里的情况比较特殊，需要找到整个区间，所以需要两遍查找，并且一个是找到小于target<br>的最大索引，一个是找到大于target的最大索引，代码参考<a href="https://discuss.leetcode.com/topic/5891/clean-iterative-solution-with-two-binary-searches-with-explanation/2" target="_blank" rel="noopener">leetcode discuss</a>,这位仁<br>兄也做了详细的分析解释。  </p>
