-/* ================================================================ */
-
-/*
- * NOTE 1:
- * -------
- *
- * All checks done in this file are intentionally placed in a public
- * header file which is pulled by curl/curl.h when an application is
- * being built using an already built libcurl library. Additionally
- * this file is also included and used when building the library.
- *
- * If compilation fails on this file it is certainly sure that the
- * problem is elsewhere. It could be a problem in the curlbuild.h
- * header file, or simply that you are using different compilation
- * settings than those used to build the library.
- *
- * Nothing in this file is intended to be modified or adjusted by the
- * curl library user nor by the curl library builder.
- *
- * Do not deactivate any check, these are done to make sure that the
- * library is properly built and used.
- *
- * You can find further help on the libcurl development mailing list:
- * http://cool.haxx.se/mailman/listinfo/curl-library/
- *
- * NOTE 2
- * ------
- *
- * Some of the following compile time checks are based on the fact
- * that the dimension of a constant array can not be a negative one.
- * In this way if the compile time verification fails, the compilation
- * will fail issuing an error. The error description wording is compiler
- * dependent but it will be quite similar to one of the following:
- *
- *   "negative subscript or subscript is too large"
- *   "array must have at least one element"
- *   "-1 is an illegal array size"
- *   "size of array is negative"
- *
- * If you are building an application which tries to use an already
- * built libcurl library and you are getting this kind of errors on
- * this file, it is a clear indication that there is a mismatch between
- * how the library was built and how you are trying to use it for your
- * application. Your already compiled or binary library provider is the
- * only one who can give you the details you need to properly use it.

@@ -182,11 +182,11 @@ TDengine 分布式架构的逻辑结构图如下：
 
 **集群对外连接:** TDengine集群可以容纳单个、多个甚至几千个数据节点。应用只需要向集群中任何一个数据节点发起连接即可，连接需要提供的网络参数是一数据节点的End Point(FQDN加配置的端口号）。通过命令行CLI启动应用taos时，可以通过选项-h来指定数据节点的FQDN, -P来指定其配置的端口号，如果端口不配置，将采用TDengine的系统配置参数serverPort。
 
-**集群内部通讯**: 各个数据节点之间通过TCP/UDP进行连接。一个数据节点启动时，将获取mnode所在的dnode的EP信息，然后与系统中的mnode建立起连接，交换信息。获取mnode的EP信息有三步，1：检查mnodeEpList文件是否存在，如果不存在或不能正常打开获得mnode EP信息，进入第二步；2：检查系统配置文件taos.cfg, 获取节点配置参数first, second，（这两个参数指定的节点可以是不带mnode的普通节点，这样的话，节点被连接时会尝试重定向到mnode节点）如果不存在或者taos.cfg里没有这两个配置参数，或无效，进入第三步；3：将自己的EP设为mnode EP, 并独立运行起来。获取mnode EP列表后，数据节点发起连接，如果连接成功，则成功加入进工作的集群，如果不成功，则尝试mnode EP列表中的下一个。如果都尝试了，但连接都仍然失败，则休眠几秒后，再进行尝试。

 **MNODE的选择:** TDengine逻辑上有管理节点，但没有单独的执行代码，服务器侧只有一套执行代码taosd。那么哪个数据节点会是管理节点呢？这是系统自动决定的，无需任何人工干预。原则如下：一个数据节点启动时，会检查自己的End Point, 并与获取的mnode EP List进行比对，如果在其中，该数据节点认为自己应该启动mnode模块，成为mnode。如果自己的EP不在mnode EP List里，则不启动mnode模块。在系统的运行过程中，由于负载均衡、宕机等原因，mnode有可能迁移至新的dnode，但一切都是透明的，无需人工干预，配置参数的修改，是mnode自己根据资源做出的决定。
 
-**新数据节点的加入**：系统有了一个数据节点后，就已经成为一个工作的系统。添加新的节点进集群时，有两个步骤，第一步：使用TDengine CLI连接到现有工作的数据节点，然后用命令”create dnode"将新的数据节点的End Point添加进去; 第二步：在新的数据节点的系统配置参数文件taos.cfg里，将first, second参数设置为现有集群中任意两个数据节点的EP即可。具体添加的详细步骤请见详细的用户手册。这样就把集群一步一步的建立起来。

 **重定向**：无论是dnode还是taosc，最先都是要发起与mnode的连接，但mnode是系统自动创建并维护的，因此对于用户来说，并不知道哪个dnode在运行mnode。TDengine只要求向系统中任何一个工作的dnode发起连接即可。因为任何一个正在运行的dnode，都维护有目前运行的mnode EP List。当收到一个来自新启动的dnode或taosc的连接请求，如果自己不是mnode，则将mnode EP List回复给对方，taosc或新启动的dnode收到这个list, 就重新尝试建立连接。当mnode EP List发生改变，通过节点之间的消息交互，各个数据节点就很快获取最新列表，并通知taosc。
