Faced with complex such as operating system of a project, we should learn how to learn what, where to start? Here is a guide to learning:There are a lot of things to learn about chromium code base, such as: processes and their relationships, how the IPC works, URL loading processes, and micro-hierarchies such as smart pointers, message loops, threading usages, threading models, string, and so on.Learn Chromium's "behavior":Coding style:Http://www.chro

Last mention of the Chromium browser in the base common General Library of the memory allocator allocator, which used the three-way library tcmalloc, Jemalloc; For these two memory allocators, personally recommended, for memory, it is best to maintain the memory pool yourself In addition, the use of its own memory allocation method under Windows, and a third-party library can refer to: http://www.360doc.com/content/13/0915/09/8363527_314549128.shtml A

Most of Chromium's internationalized resource files are under directory src\chrome\app\resources, for example, we select a sentence in the settings.System, continue to run the background app after shutting down ChromiumIn the resource file Src\chrome\app\resources\chromium_strings_zh-cn.xtb, you can find this sentenceIn fact, it corresponds to the src/chrome/app/chromium_strings.grd of the following text internationalization translation.This translation ID is an ID value calculated from the tran

Similarities and differences between webkit2 and Chromium Process architecture 1. detailed comparison of the differences between the two 2. Personal Opinion Chromium's label process architecture separates UI from rendering and implements "rendering as a service" in a concise way. Webkit2 directly implements the multi-process architecture based on the concept of "rendering is a service", which is the fundamental difference between the two. H

Such a way is ubiquitous in chromium. Don't be so dizzy as to be confused.2. The Appidconveter class is just an auxiliary class for resource ID conversions.3. Mainview controls the behavior of the view in the window, which simply tells the size of the view. In Mainwindowdelegate, the windo

Base::P If you want to execute a task that requires an incoming scoped pointer, you can use it to convert, which also avoids copying, but is similar to move semantics. Base::constref Like a constant reference, you do not want a copy of the bind process to be used.
