Static Code checking tool FindBugs why and how to use FindBugsThe static analysis tool promises to find bugs that are already in the code without the hassle of a developer. Of course, if you have many years of experience in writing, you will know that these commitments are n

HMaster startup code analysis for source code analysis of HBase1.0.0 (1), hbase1.0.0hmaster This article is not really about startup code parsing. This article mainly analyzes the startHMaster part from the startup process. This article will introduce HBase's pseudo-distribu

each field, it starts with writefieldbegin. The writing segment type and the sequence number of the field. If the field is a struct class, you can call this class's own encoding method write (tprotocol ). Thrift generates classes for each struct, which define the encoding and decoding methods of this class. End with writestructend. 2. the decoding method starts from readstructbegbegin, reads the field metadata readfieldbegin, reads the field type of 1 byte, And the byte sequence number of 2 fie

, 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

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

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

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
