Static Analysis

Static analysis or also known as Static Code Analysis is a process to analyze the source code of a software without running the software itself. Static Analysis are generally used by developers as part of the development and component testing process.

Benefits...

Detecting the possible bugs on your code (crash, memory leak, stack overflow, buffer overflow, etc),

Find any vulnerabilities in the corner of your applications (clumsy developer miss),

Finding possible wrong logic and any bad practice on your project,

Finding areas of the code that may need more testing or deeper review,

Benefits… (cont)

Finding duplicate code which is could be moved into another methods to reduce code complexity,

Identifying design issues such as Cyclomatic Complexity and helping reduce the code complexity improve maintainability,

Identifying potential software quality issues before the code moves to production.

Setting up SQ Server. (Mac)

$ brew install sonar

Setting up SQ Server. (Linux)# download SonarQube

$ wget http://dist.sonar.codehaus.org/sonarqube-5.X.zip

# Unzip and move file into /opt/

$ unzip sonarqube-5.X.zip$ mv sonarqube-5.X /opt/sonar

Setting up Databases (MySQL)$ mysql -u root -p

CREATE DATABASE sonar CHARACTER SET utf8 COLLATE utf8_general_ci;CREATE USER 'sonar' IDENTIFIED BY 'sonar';GRANT ALL ON sonar.* TO 'sonar'@'%' IDENTIFIED BY 'sonar';GRANT ALL ON sonar.* TO 'sonar'@'localhost' IDENTIFIED BY 'sonar';FLUSH PRIVILEGES;

Connect SQ to Databases

Open /opt/sonar/conf/sonar.properties

sonar.jdbc.username=sonarsonar.jdbc.password=sonar

sonar.jdbc.url=jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance

Setting up web server.

Open /opt/sonar/conf/sonar.properties

sonar.web.host=127.0.0.1sonar.web.context=/sonarsonar.web.port=9000

Starting sonar...

$ sonar start

Or

$ sudo sonar start
