I used Hudson to deploy my Web project to tomcat on the test server in my usual work. The Hudson itself is integrated with SVN, Git, MAVEN, and supports the addition of various plugins. But if you use Hudson, I need to configure two tasks: one to package the project into a war, and the other to deploy the packaged war package to Tomcat on the target server. Although the task only needs to be configured once

Make sure your published the friendlyhello image you created by pushing it to a registry. We'll be using the that shared image here. Be sure your image works as a deployed container.

First, the concept of smart pointersThe smart pointer is a class, not a pointer , and the smart pointer automatically frees the system resources that are used by the contained pointer when it is no longer in use, rather than manually releasing it.Principle: The smart pointer encapsulates the AddRef () function and the

To address the problem of C + + memory leaks, C++11 introduced smart pointers (smart Pointer).The principle of smart pointers is to accept a well-applied memory address, construct a smart pointer object stored on the stack, there is an important principle in C + +, at the end of the function (whether it is normal retur

a class to add a layer of packaging, the simplest is like this: "Class My_intptr{Publicint* m_p;My_intptr (int* p) {m_p = P;}~my_intptr () {delete m_p;}};............My_intptr Pi (new int);* (pi.m_p) = 10;............"Here we can safely use my_intptr without worrying about memory leaks: Once the PI variable is destroyed, we know that the memory block pointed to by PI.P is bound to be freed. But it would be too much trouble to access its members every time you use MY_INTPTR. To do this, you can

Reference counting smart pointerI. Introduction Since the C ++ language does not have an automatic memory reclaim mechanism, the programmer must manually delete the new memory each time. When the programmer forgets to delete, the process is too complex and eventually leads to the absence of delete, exceptions lead to premature exit of the program, and the absence of delete execution is not uncommon. Using Smart
