Mojo for Chromium DevelopersoverviewThis document contains the minimum amount of information needed for a developer-start using Mojo in Chromium. For more detailed documentation on the C + + bindings, see this link.TerminologyA message pipe is a pair of endpoints. Each endpoint have a queue of incoming messages, and writing a message to one endpoint effectively enqueues this message on The other endpoint. M

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

, Instead, the Documentthreadableloader class ultimately relies on the implementation of Weburlloaderimpl to send a URL request to the main process Weburlloaderimpl (Weburlloaderimpl process see:/HTTP) www.cnblogs.com/fangkm/p/3784660.html).The Associatedurlloader object is associated with the frame object, and the request is canceled when the Stoploading method of the webframe is called.The Bufferedresourceloader internally maintains an extensible memory buffer to hold the requested video data.

Every time I try to look at the implementation of the specific logic in chromium kernel, it's time to look at the code and find the logic. Of course, a lot of information on the Internet can be seen, but every time I read this information, I would like to ask: really so? Does the new version of kernel change this logic?So, in order to let themselves be confused, or to see the source code, a little bit to see the call stack. Then we can understand the

Chromium OS lags behind Chrome OS If you use the above method to successfully use chromium OS, Don't be proud of it too early. Since it is free, there must be a reduction. The difference between the two is explained by Google: 1. You can download and modify chromium OS for free. Chrome OS is only available to brand manufacturers for specific notebook models (that

Chromium is a plan launched by Google to develop Google Chrome, its browser, so Chromium is equivalent to Chrome's engineering version or experimental version (although Chrome also has beta version), and new features will be implemented on Chromium first, it will be applied to Chrome only after verification, so Chrome's functions will be relatively stable (in fac
