klocwork static code analysis

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

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,

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

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

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

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

Learn Java concurrency programming have to understand java.util.concurrent this package, this package has many of the concurrency tools we often use, such as: Reentrantlock, Countdownlatch, Cyclicbarrier, Semaphore and so on. The underlying implementations of these classes depend on the Abstractqueuedsynchronizer class, which shows the importance of this class. So in the Java Concurrency Series I first abstractqueuedsynchronizer this class to analyze, because this class is more important, and th
