Recently i got interested in learning internals of Chrome / ChromeOS / WebKit. So i started to go through the source code. Without much documentation and guidance it was difficult to understand. In my analysis i found the following useful links to learn/understand the chrome internals.
Chrome directory layout is quite difficult to understand and it is quite difficult to analyze this large codebase. You can’t run grep now and then and navigate.
Best place to do some quick search:
X:\src\chrome\test\data\ (in the chrome checkout)
And run the Doxygen on the codebase, believe me it generates lot of interesting class layout. It helps us in understanding the codebase bit quicker.
