sonar static code analysis

the course of our analysis of the pipeline later, you can see the code to do the work. Summarize: This paper simply introduces the data structure of the message defined in ZEROMQ and related operations, basically zeromq the data structure of the message using variable Long data structure to store data, but also to the small message for memory allocation optimization above, directly using stack allocation,

1. Introduction of toolsInfer is a static program analysis tool that can be used to analyze Java, C, and objective-c programs, which are written in OCaml.Infer was first deployed on Facebook to analyze each line of code before it was released for mobile apps, and now Facebook uses this tool to analyze the Android, IOS apps that are being developed, including Face

Before formally entering the test, it is helpful to do some static code analysis and code review to improve the quality and the system, the above is the data proofPMD It is a Java source code parser based on a static rule set that

Static scanStatic Analysis1, can be in the coding phase, the development of self-code inspection. Early detection of code pitfalls.2, directly analyze the source code to find errors in the program, without the need to actually run.3. Automatic detection of bugs in objective-c programs, memory leaks and other problems.4

The concept of static analysis has been put forward for years, and the technology used to evaluate and diagnose code has matured over the past few years. Software review tools exist in almost every language. These reviews can isolate undesirable code in areas such as arrays, loops, coding styles, design, copying

Code. See the following example in detail:Char * strcpy (char *, const char *);Const char c = 'a ';Const char * P = C;Void main (){Char Buf [100];C = 'B ';* P = 'C ';Strcpy (p, Buf );...Here, both C and * P point to static variables and cannot be modified. The above code obviously violates this rule and produces error (11). In addition, when P is passed into st

Objective:PMD is a static code analysis tool that can automatically detect various potential defects as well as unsafe or non-optimized code.PMD is more focused on pre-detection flaws, and it provides a highly configurable rich set of rules that users can easily configure to treat specific projects using those rules.Installation and use:1. How to install the PMD

Now begin to study the first step, how to define your own routing rules to achieve pseudo static functional requirements. The basic principle of realization of the following diagram: First, about namespaces. The function of routing is to make all ASP.net Web site development available, so DLLs are not in MVC, but in system.web System.web.Routing. Now we implement the custom routing functionality in MVC3 (inheriting routebase, overriding Routedata

Cppcheck is a analysis tool for C/c++code. Unlike C + + compilers and many other analysis tools, it doesn ' t detect syntax errors. Cppcheck only detects the types of bugs, the compilers normally fail to detect. The goal is no false positives.Cppcheck is rarely wrong about reported errors. But there is many bugs that it doesn ' t detect.It can check for files tha

It has been about 4 months since I studied PMD and customized the rules in my work. In fact, PMD has many worthy of my learning source code, but because of time did not have to pen.

field .html can jump to the test. php regex matching field stored in virtual memory matching $1 3. mod_rewrite rule modifier 1) R forces external redirection2) F disables the URL and returns the 403HTTP status code.3) if G forces the URL to be GONE, the response HTTP status code is returned.4) P enforces proxy forwarding.5) L indicates that the current rule is the last rule, and the rule is overwritten aft

loop (sbsc_use_stringbuffer_concatenation)The problem description is already clear, try not to use String in the loop, instead of using StringBuffer: The method seems to is building a String using concatenation in a loop. In each iteration, the string was converted to a stringbuffer/stringbuilder, appended to, and converted back to a String. This can leads to a cost quadratic in the number of iterations, as the growing string was recopied in each iteration. Better performance can be obtained by

Below is a list of some tools that can help you examine your Java source code for potential problems: 1. pMD from http://pmd.sourceforge.net/ License: PMD is licensed under a "BSD-style" License PMD scans Java source code and looks for potential problems like: * Possible bugs-Empty try/catch/finally/switch statements* Dead Code-unused local variables, par

Sonarqube Scanner, as a code scanning tool, through which the code of the project is read and sent to the Sonarqube server to allow Sonarqube code analysis.It can be considered that Sonarqube scanner is the client of Sonarqube. Sonarqube scanner is easy to integrate with different types of build tools and Maven project consolidation A plug-in for the Sonarqube Sc

to reverse check the requirements coverage (use case) test is fully complete. If you do coverage testing. We can use a number of online popular coverage tools, this chapter mainly introduces Jacoco this tool. A comparative analysis of Emma and Jacoco: Java main code coverage tools on the market: EMMA, Jacoco Summarize the individual's understanding of the Jacoco advantage: (1) Jacoco supports branch cover

Android source code analysis-system_server Process Analysis In the previous blog, we analyzed the Zygote process. We know that the Zygote process creates an important process-the system_server process and enters an infinite loop, later, an important task in the Android system was handed over to the system_server process. As the eldest son process of zygote, The s
