Netty3 Source Code Analysis-NIO Server binding process AnalysisThe better a framework encapsulates, the better it is for our high-speed coding. But it hides a lot of details and principles. But the source code can reveal everything.The server-side code is in the specified good ChannelFactory. Set the options. Then the

Part of the data from Shen shouzhong, Zhang yuqing "crawler-based XSS vulnerability detection tool design and implementation": http://download.csdn.net/detail/xihuanqiqi/4655513 I. Graphic analysis of XSS-scan system principles the system modules they wrote are relatively clear and easy to understand. My explanation is as follows: 1. first, use the crawler module to capture the page url (that is, put the URL in a queue called the crawler URL Queue) 2

Citation link: "Flappy Pig" by the master cracked, code analysisSee this article two days ago, have a kind of IOCCC style. Can not help but do the following analysis, the shortcomings of the hope that there is an expert in the liberal enlighten, first thanked.Unfortunately, it is automatically generated. But there are a lot of places that are worth learning._=~[];//-1;/* uses an empty array and a weakly typ

February 23, 2016, learn, analyze Ansible code Ansible is a tool for bulk deployment used in operations, which is itself a framework, specific deployment and architectural analysis, and the following article is good. Http://os.51cto.com/art/201409/451927_all.htm First analyze the main file ansible, and the code and comments are as follows: 1. from __future__ Imp

Spring Source Code Analysis-detailed analysis of BeanFactory system interfacesThe previous blog post analyzed Spring's Resource class Resouce. I started to analyze the IOC part of Spring today. As we all know, IOC is the most fascinating part of the Spring framework. Its most important interface is BeanFactory. BeanFactory has a huge inheritance and implementatio

If there is a PIPE2 interface, the PIPE2 interface is used to create the #if defined (event__have_pipe2) if (Pipe2 (FD, o_nonblock| o_cloexec) = = 0) return 0; #endif//If there is no PIPE2, a pipe is used to create #if defined (event__have_pipe) if (pipe (FD) = = 0) {if (Evutil_fast_socke T_nonblocking (Fd[0])

. Others are supported. What exactly are the Fix channels? For details, see the following table: In general, to create an L2CAP channel, a corresponding cid value is required. This is probably the meaning. 5.6.4 Implementation of the assignment of MnS in bluez In 5.6.2, we have a detailed description of how the MNS are defined in spec. Next we will continue to look at how the MNS are implemented in bluez code. Int l2cap_add_psm (struct l2cap_chan

Tags: nosql database redis Memory Database Structure The last time I analyzed the structure analysis of the client, the idea was simple and clear. Finally, I learned how to implement the server. The server is the top priority in redis, it basically contains all the knowledge points involved in the previous module. We can see from the redis header file that redis. the H code volume has already exceeded more

Java concurrent series of AbstractQueuedSynchronizer source code analysis (summary analysis ), To learn Java concurrent programming, you have to understand the java. util. concurrent package. This package contains many frequently used concurrent tool classes, such as ReentrantLock, CountDownLatch, CyclicBarrier, and Semaphore. The underlying implementation of the

Since the source code of the CR is not directly disclosed, we need to use some tools to snoop on its secrets. The following tools are required to analyze the CRCs: MS robotic studio express 2008r2, this does not need to be explained, install it to get Reflector filedisassembler, reflector has two roles: one is to decompile the DLL file of the CR to the C # language, and the other is to directly analyze the content of the CR, these analyses are

Bbinder are both representative classes of binder communication in Android, where Bpbinder is the proxy class that the client uses to interact with the server, and P stands for proxy, while Bbinder is the destination of the interaction; Bpbinder and Bbinder correspond to each other, the binder system will be handle to identify the corresponding bbinder; Bnservicemanager in the n represents the native, and the bn corresponds to the Bpservicemanager, which represents the ServiceManager bu

busEventbus's Code:public void Register (object object) {MultimapFinder. findallhandlers (object);Handlersbytype.putall (Methodsinlistener);}When the register is Eventbus, a finder is used to find the @subscribe method in the object of the register. and classify according to EventType, put in Handlersbytype. This way, when Eventbus post a new event, the corresponding EventHandler can be called according to the EventType.The event bus registers the application and, as explained above, looks for

Tcprstat is used by Percona to monitor MySQL response time. However, any response time running on the TCP protocol can be used.Tcprstat, like Tcpdump, uses the Libpcap library to grab packets and then analyzes the crawled TCP packets through the program.1, through the analysis of the source IP and destination IP, see that IP is the local IP, to determine whether the package (Request packet) or out of the package (response package).2, if the packet dat

will be transferred to go to execute subroutine code, in order to be able to accurately return when the subroutine executes, need to push the address of the next instruction of the call instruction into the stack. Then create a new stack for the subroutine, the assembly instructions are as follows: PUSHL%EBP MOVL%esp,%EBP The PUSHL%ebp instruction pushes the base address of the stack of the keynote program into the stack, and ESP,EB

functions. Let's look at the definition part of the constructor. In fact, these functions basically call the following create function family: void create(int rows, int cols, int type); void create(Size size, int type); void create(int ndims, const int* sizes, int type); For example, in the constructor mat: MAT (INT rows, int cols, int type: inline Mat::Mat(Size _sz, int _type) : size(rows){ initEmpty(); create( _sz.height, _sz.width, _type );} So the essence of the entire mat const

})();+ function A () {function body}();In the JQuery source, the method passes through the window and undefined two parameters.window: Because when the function is called, it needs to find the variable value, and if the current function scope does not have the variable, it will go up to the previous level to find, directly into the window, can reduce the search time, improve efficiency.Undefined: After the landlord Test in IE 8, the undefined property value can be modified, at this time the inco

from Destpos to Destpos+length-1. Because it is a native method, it is not visible in the JDK, but you can view the source code in the OPENJDK. The function actually eventually calls the C language's memmove () function, so it can guarantee the correct copying and movement of elements within the same array, which is much more efficient than the general method of replication, and is well suited for batch processing of arrays . Java strongly recommends
