### Prepare development environment
1. sudo apt install
build-essential cmake net-tools python-pip python-setuptools python3-pip
python3-setuptools valgrind psmisc curl
2. git clone <https://github.com/taosdata/TDengine>; cd TDengine
3. mkdir debug; cd debug; cmake ..; make ; sudo make install
4. pip install ../src/connector/python ; pip3 install
../src/connector/python
5. pip install numpy; pip3 install numpy (numpy is required only if you need to run querySort.py)
> Note: Both Python2 and Python3 are currently supported by the Python test
> framework. Since Python2 is no longer officially supported by Python Software
> Foundation since January 1, 2020, it is recommended that subsequent test case
> development be guaranteed to run correctly on Python3.
> For Python2, please consider being compatible if appropriate without
> additional burden.
>
> If you use some new Linux distribution like Ubuntu 20.04 which already do not
> include Python2, please do not install Python2-related packages.

### How to run Python test suite
1. cd \<TDengine\>/tests/pytest
2. ./smoketest.sh \# for smoke test
3. ./smoketest.sh -g \# for memory leak detection test with valgrind
4. ./fulltest.sh \# for full test
> Note1: TDengine daemon's configuration and data files are stored in
> \<TDengine\>/sim directory. As a historical design, it's same place with
> TSIM script. So after the TSIM script ran with sudo privilege, the directory
> has been used by TSIM then the python script cannot write it by a normal
> user. You need to remove the directory completely first before running the
> Python test case. We should consider using two different locations to store
> for TSIM and Python script.
> Note2: if you need to debug crash problem with a core dump, you need
> manually edit smoketest.sh or fulltest.sh to add "ulimit -c unlimited"
> before the script line. Then you can look for the core file in
> \<TDengine\>/tests/pytest after the program crash.
### How to add a new test case
**1. TSIM test cases:**
TSIM was the testing framework has been used internally. Now it still be used to run the test cases we develop in the past as a legacy system. We are turning to use Python to develop new test case and are abandoning TSIM gradually.
**2. Python test cases:**
**2.1 Please refer to \<TDengine\>/tests/pytest/insert/basic.py to add a new
test case.** The new test case must implement 3 functions, where self.init()
and self.stop() simply copy the contents of insert/basic.py and the test
logic is implemented in self.run(). You can refer to the code in the util
directory for more information.
**2.2 Edit smoketest.sh to add the path and filename of the new test case**
Note: The Python test framework may continue to be improved in the future,
hopefully, to provide more functionality and ease of writing test cases. The
method of writing the test case above does not exclude that it will also be
affected.
**2.3 What test.py does in detail:**
test.py is the entry program for test case execution and monitoring.
test.py has the following functions.
\-f --file, Specifies the test case file name to be executed
-p --path, Specifies deployment path
\-m --master, Specifies the master server IP for cluster deployment
-c--cluster, test cluster function
-s--stop, terminates all running nodes
\-g--valgrind, load valgrind for memory leak detection test
\-h--help, display help
**2.4 What util/log.py does in detail:**
log.py is quite simple, the main thing is that you can print the output in
different colors as needed. The success() should be called for successful
test case execution and the success() will print green text. The exit() will
print red text and exit the program, exit() should be called for test
failure.
**util/log.py**
...
    def info(self, info):
        printf("%s %s" % (datetime.datetime.now(), info))
 
    def sleep(self, sec):
        printf("%s sleep %d seconds" % (datetime.datetime.now(), sec))
        time.sleep(sec)
 
    def debug(self, err):
        printf("\\033[1;36m%s %s\\033[0m" % (datetime.datetime.now(), err))
 
    def success(self, info):
        printf("\\033[1;32m%s %s\\033[0m" % (datetime.datetime.now(), info))
 
    def notice(self, err):
        printf("\\033[1;33m%s %s\\033[0m" % (datetime.datetime.now(), err))
 
    def exit(self, err):
        printf("\\033[1;31m%s %s\\033[0m" % (datetime.datetime.now(), err))
        sys.exit(1)
 
    def printNoPrefix(self, info):
        printf("\\033[1;36m%s\\033[0m" % (info)
...
**2.5 What util/sql.py does in detail:**
SQL.py is mainly used to execute SQL statements to manipulate the database,
and the code is extracted and commented as follows:
**util/sql.py**
\# prepare() is mainly used to set up the environment for testing table and
data, and to set up the database db for testing. do not call prepare() if you
need to test the database operation command.
def prepare(self):
tdLog.info("prepare database:db")
self.cursor.execute('reset query cache')
self.cursor.execute('drop database if exists db')
self.cursor.execute('create database db')
self.cursor.execute('use db')
...
\# query() is mainly used to execute select statements for normal syntax input
def query(self, sql):
...
\# error() is mainly used to execute the select statement with the wrong syntax
input, the error will be caught as a reasonable behavior, if not caught it will
prove that the test failed
def error()
...
\# checkRows() is used to check the number of returned lines after calling
query(select ...) after calling the query(select ...) to check the number of
rows of returned results.
def checkRows(self, expectRows):
...
\# checkData() is used to check the returned result data after calling
query(select ...) after the query(select ...) is called, failure to meet
expectation is
def checkData(self, row, col, data):
...
\# getData() returns the result data after calling query(select ...) to return
the resulting data after calling query(select ...)
def getData(self, row, col):
...
\# execute() used to execute sql and return the number of affected rows
def execute(self, sql):
...
\# executeTimes() Multiple executions of the same sql statement
def executeTimes(self, sql, times):
...
\# CheckAffectedRows() Check if the number of affected rows is as expected
def checkAffectedRows(self, expectAffectedRows):
...
### CI submission adoption principle.
- Every commit / PR compilation must pass. Currently, the warning is treated
as an error, so the warning must also be resolved.
- Test cases that already exist must pass.
- Because CI is very important to support build and automatically test
procedure, it is necessary to manually test the test case before adding it
and do as many iterations as possible to ensure that the test case provides
stable and reliable test results when added.
> Note: In the future, according to the requirements and test development
> progress will add stress testing, performance testing, code style,
> and other features based on functional testing.

# 如何在 windows环境下使用jdbc进行TDengine应用开发
本文以windows环境为例，介绍java如何进行TDengine开发应用
## 环境准备
（1）安装jdk
官网下载jdk-1.8，下载页面：https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html
安装，配置环境变量，把jdk加入到环境变量里。
命令行内查看java的版本。
```shell
>java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)
```
（2）安装配置maven
官网下载maven，下载地址：http://maven.apache.org/download.cgi
配置环境变量MAVEN_HOME，将MAVEN_HOME/bin添加到PATH
命令行里查看maven的版本
```shell
>mvn --version
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T03:39:06+08:00)
Maven home: D:\apache-maven-3.5.0\bin\..
Java version: 1.8.0_131, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk1.8.0_131\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
```
为了加快maven下载依赖的速度，可以为maven配置mirror，修改MAVEN_HOME\config\settings.xml文件
```xml
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<!-- 配置本地maven仓库的路径 -->
<localRepository>D:\apache-maven-localRepository</localRepository>
<mirrors>
<!-- 配置阿里云Maven镜像仓库 -->
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
<profiles>
<!-- 配置jdk，maven会默认使用java1.8 -->
<profile>
<id>jdk-1.8</id>
<activation>
<activeByDefault>true</activeByDefault>
<jdk>1.8</jdk>
</activation>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
</properties>
</profile>
</profiles>
</settings>
```
（3）在linux服务器上安装TDengine-server
在taosdata官网下载TDengine-server，下载地址：https://www.taosdata.com/cn/all-downloads/
在linux服务器上安装TDengine-server
```shell
# tar -zxvf package/TDengine-server-2.0.1.1-Linux-x64.tar.gz
# cd TDengine-server/
# ./install.sh
```
启动taosd
```shell
# systemctl start taosd
```
在server上用taos连接taosd
```shell
# taos
taos> show dnodes;
id | end_point | vnodes | cores | status | role | create_time |
==================================================================================================================
1 | td01:6030 | 2 | 4 | ready | any | 2020-08-19 18:40:25.045 |
Query OK, 1 row(s) in set (0.005765s)
```
如果可以正确连接到taosd实例，并打印出databases的信息，说明TDengine的server已经正确启动。这里查看server的hostname
```shell
# hostname -f
td01
```
注意，如果安装TDengine后，使用默认的taos.cfg配置文件，taosd会使用当前server的hostname创建dnode实例。之后，在client也需要使用这个hostname来连接taosd。
（4）在windows上安装TDengine-client
在taosdata官网下载taos客户端，下载地址：
https://www.taosdata.com/cn/all-downloads/
下载后，双击exe安装。
修改client的hosts文件（C:\Windows\System32\drivers\etc\hosts），将server的hostname和ip配置到client的hosts文件中
```
192.168.236.136 td01
```
配置完成后，在命令行内使用taos shell连接server端
```shell
C:\TDengine>taos -h td01
Welcome to the TDengine shell from Linux, Client Version:2.0.1.1
Copyright (c) 2017 by TAOS Data, Inc. All rights reserved.
taos> show databases;
name | created_time | ntables | vgroups | replica | quorum | days | keep0,keep1,keep(D) | cache(MB) | blocks | minrows | maxrows | wallevel | fsync | comp | precision | status |
===================================================================================================================================================================================================================================================================
test | 2020-08-19 18:43:50.731 | 1 | 1 | 1 | 1 | 2 | 3650,3650,3650 | 16 | 6 | 100 | 4096 | 1 | 3000 | 2 | ms | ready |
log | 2020-08-19 18:40:28.064 | 4 | 1 | 1 | 1 | 10 | 30,30,30 | 1 | 3 | 100 | 4096 | 1 | 3000 | 2 | us | ready |
Query OK, 2 row(s) in set (0.068000s)
```
如果windows上的client能够正常连接，并打印database信息，说明client可以正常连接server了。
## 应用开发
（1）新建maven工程，在pom.xml中引入taos-jdbcdriver依赖。
```xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.taosdata.demo</groupId>
<artifactId>JdbcDemo</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>com.taosdata.jdbc</groupId>
<artifactId>taos-jdbcdriver</artifactId>
<version>2.0.8</version>
</dependency>
</dependencies>
</project>
```
（2）使用jdbc查询TDengine数据库
下面是示例代码：
```java
public class JdbcDemo {
public static void main(String[] args) throws Exception {
Connection conn = getConn();
Statement stmt = conn.createStatement();
// create database
stmt.executeUpdate("create database if not exists db");
// use database
stmt.executeUpdate("use db");
// create table
stmt.executeUpdate("create table if not exists tb (ts timestamp, temperature int, humidity float)");
// insert data
int affectedRows = stmt.executeUpdate("insert into tb values(now, 23, 10.3) (now + 1s, 20, 9.3)");
System.out.println("insert " + affectedRows + " rows.");
// query data
ResultSet resultSet = stmt.executeQuery("select * from tb");
Timestamp ts = null;
int temperature = 0;
float humidity = 0;
while(resultSet.next()){
ts = resultSet.getTimestamp(1);
temperature = resultSet.getInt(2);
humidity = resultSet.getFloat("humidity");
System.out.printf("%s, %d, %s\n", ts, temperature, humidity);
}
}
public static Connection getConn() throws Exception{
Class.forName("com.taosdata.jdbc.TSDBDriver");
String jdbcUrl = "jdbc:TAOS://td01:0/log?user=root&password=taosdata";
Properties connProps = new Properties();
connProps.setProperty(TSDBDriver.PROPERTY_KEY_CHARSET, "UTF-8");
connProps.setProperty(TSDBDriver.PROPERTY_KEY_LOCALE, "en_US.UTF-8");
connProps.setProperty(TSDBDriver.PROPERTY_KEY_TIME_ZONE, "UTC-8");
Connection conn = DriverManager.getConnection(jdbcUrl, connProps);
return conn;
}
}
```
（3）测试jdbc访问tdengine的sever实例
console输出：
```
insert 2 rows.
2020-08-26 00:06:34.575, 23, 10.3
2020-08-26 00:06:35.575, 20, 9.3
```
## 指南
（1）如何设置主机名和hosts
在server上查看hostname和fqdn
```shell
查看hostname
# hostname
taos-server
查看fqdn
# hostname -f
taos-server
```
windows下hosts文件位于：
C:\\Windows\System32\drivers\etc\hosts
修改hosts文件，添加server的ip和hostname
```s
192.168.56.101 node5
```
（2）什么是fqdn？
> 什么是FQDN？
>
> FQDN（Full qualified domain name）全限定域名，fqdn由2部分组成：hostname+domainname。
>
> 例如，一个邮件服务器的fqdn可能是：mymail.somecollege.edu，其中mymail是hostname（主机名），somcollege.edu是domainname（域名）。本例中，.edu是顶级域名，.somecollege是二级域名。
>
> 当连接服务器时，必须指定fqdn，然后，dns服务器通过查看dns表，将hostname解析为相应的ip地址。如果只指定hostname（不指定domainname），应用程序可能服务解析主机名。因为如果你试图访问不在本地的远程服务器时，本地的dns服务器和可能没有远程服务器的hostname列表。

# How to Run the JDBC Demo Code On Linux OS
TDengine's JDBC demo project is organized in a Maven way so that users can easily compile, package and run the project. If you don't have Maven on your server, you may install it using
```
sudo apt-get install maven
```
## Install TDengine Client
Make sure you have already installed a tdengine client on your current develop environment.
Download the tdengine package on our website: ``https://www.taosdata.com/cn/all-downloads/`` and install the client.
## Run jdbcDemo using mvn plugin
run command:
```
mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo"
```
and run with your customed args
```
mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo" -Dexec.args="-host [HOSTNAME]"
```
## Compile the Demo Code and Run It
To compile taos-jdbcdriver, go to the source directory ``TDengine/src/connector/jdbc`` and execute
```
mvn clean package -Dmaven.test.skip=true
```
To compile the demo project, go to the source directory ``TDengine/tests/examples/JDBC/JDBCDemo`` and execute
```
mvn clean package assembly:single
```
To run JDBCDemo.jar, go to ``TDengine/tests/examples/JDBC/JDBCDemo`` and execute
```
java -Djava.ext.dirs=../../../../src/connector/jdbc/target:$JAVA_HOME/jre/lib/ext -jar target/JDBCDemo-SNAPSHOT-jar-with-dependencies.jar -host [HOSTNAME]
```

## TDengine Spring JDBC Template Demo
`Spring JDBC Template` 简化了原生 JDBC Connection 获取释放等操作，使得操作数据库更加方便。
### 配置
修改 `src/main/resources/applicationContext.xml` 文件中 TDengine 的配置信息：
```xml
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.taosdata.jdbc.TSDBDriver"></property>
<property name="url" value="jdbc:TAOS://127.0.0.1:6030/log"></property>
<property name="username" value="root"></property>
<property name="password" value="taosdata"></property>
</bean>
<bean id = "jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate" >
<property name="dataSource" ref = "dataSource" ></property>
</bean>
```
### 打包运行
进入 `TDengine/tests/examples/JDBC/SpringJdbcTemplate` 目录下，执行以下命令可以生成可执行 jar 包。
```shell
mvn clean package
```
打包成功之后，进入 `target/` 目录下，执行以下命令就可运行测试：
```shell
java -jar SpringJdbcTemplate-1.0-SNAPSHOT-jar-with-dependencies.jar
```

这个example中，我们适配了java常见的连接池:
* HikariCP（默认）
* druid
* dbcp
* c3p0
### 说明
ConnectionPoolDemo的程序逻辑：
1. 创建到host的connection连接池
2. 创建名称为pool_test的database，创建表超级weather，创建tableSize个子表
3. 总共插入totalNumber条数据。
### 如何运行这个例子：
```shell script
mvn clean package assembly:single
java -jar target/connectionPools-1.0-SNAPSHOT-jar-with-dependencies.jar -host 127.0.0.1
```
使用mvn运行ConnectionPoolDemo的main方法，可以指定参数
```shell script
Usage:
java -jar target/connectionPools-1.0-SNAPSHOT-jar-with-dependencies.jar
-host : hostname
-poolType <c3p0| dbcp| druid| hikari>
-poolSize <poolSize>
-tableSize <tableSize>
-batchSize : 每条Insert SQL中values的数量
-sleep : 每次插入任务提交后的
```
### 日志
使用log4j，将日志和错误分别输出到了debug.log和error.log中

### 主要功能
* 创建数据库和表
```xml
<!-- weatherMapper.xml -->
<update id="createDB" >
create database if not exists test;
</update>
<update id="createTable" >
create table if not exists test.weather(ts timestamp, temperature int, humidity float);
</update>
```
* 插入单条记录
```xml
<!-- weatherMapper.xml -->
<insert id="insert" parameterType="Weather" >
insert into test.weather (ts, temperature, humidity) values (now, #{temperature,jdbcType=INTEGER}, #{humidity,jdbcType=FLOAT})
</insert>
```
* 插入多条记录
```xml
<!-- weatherMapper.xml -->
<insert id="batchInsert" parameterType="java.util.List" >
insert into test.weather (ts, temperature, humidity) values
<foreach separator=" " collection="list" item="weather" index="index" >
(now + #{index}a, #{weather.temperature}, #{weather.humidity})
</foreach>
</insert>
```
* 分页查询
```xml
