lua static code analysis

, static is limited to hiding, and for variables, static has the following two functions.2) The second function of static is to keep the contents of the variable persistent. Variables stored in the static data area are initialized at the start of the program and are the only one initialized. A total of two variables ar

JQuery source code analysis and jquery source code analysis One time I was writing jquery plug-ins, I found my js water deep and I was very comfortable with myself. Then we gradually discovered that JavaScript contains some common knowledge points such as prototype, closure, and scope. First, the main structure of jqu

Recently, I took over the whole site optimization of a hospital website. The optimized words are more like STD and abortion. The website took over and watched the news and several channels. The pages were static! Thought... Hey, you can save a lot of work. But the problem lies in this static ....All websites are static! However, you can view the source

Java Collection source code analysis (1), java Collection source code analysis The Java Collection toolkit is located under the Java. util package and contains many common data structures, such as arrays, linked lists, stacks, queues, sets, and hash tables. The Java Collection framework can be divided into the followin

Java list source code analysis, list source code analysis Three Data Structure linked lists, trees, and graphs. As one of them, the sequence table is the longest used in programming. The List interface is the implementation of sequence tables in java. It has many subinterfaces and implementation classes, which are very

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

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

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

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

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

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.

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
