Adam Roben ae1e26bddd Fix a hang on quit when application cache is used 
If you navigated to a page that used the HTML Application Cache, you'd see a
hang on quit with a backtrace like so:

BackendImpl was waiting on BrowserThread::CACHE, but that thread had already
been stopped. The solution is to destroy the BrowserContext before threads have
been stopped. We now do this in BrowserMainParts::PostMainMessageLoopRun, which
matches content_shell.

Brightray

Brightray is a static library that makes libchromiumcontent easier to use in applications.

Using it in your app

See brightray_example for a sample application written using Brightray.

Development

Prerequisites

  • Python 2.7
  • Linux:
    • Clang 3.0
  • Mac:
    • Xcode
  • Windows:
    • Visual Studio 2010 SP1

One-time setup

You must previously have built and uploaded libchromiumcontent using its script/upload script.

$ script/bootstrap http://base.url.com/used/by/script/upload

Building

$ script/build

Building Brightray on its own isn’t all that interesting, since it’s just a static library. Building it into an application (like brightray_example) is the only way to test it.
