With Google out of the picture, WebKit’s open-source developers plan removal of Chromium code and references

With Google out of the picture, WebKit’s open-source developers plan removal of Chromium code and ...

With Google’s announcement yesterday to fork WebKit and build a new rendering engine called Blink, the WebKit team has announced plans to streamline the project. Since the rendering engine no longer needs to support the Chromium port, there’s a huge slew of code that can be removed.

Here’s the high-level plan:

Concepts we plan to remove:
Layering violations in WebCore/platform, where a Page* or Frame* is passed to a function
Supplementable and Supplement
#if USE(V8)
#if !USE(JSC)
WebLayer and its scrolling implementation
Features #defines that haven’t gained traction

Specific files we plan to remove:
.gyp build files

This is actually a good thing. Leaner code should not only ease development, but should speed it up as well. Furthermore, there are also security benefits to managing less: the more complex your software gets, the more potential there is for security holes.

Here’s what Google said yesterday:

The bulk of the initial work will focus on internal architectural improvements and a simplification of the codebase. For example, we anticipate that we’ll be able to remove 7 build systems and delete more than 7,000 files—comprising more than 4.5 million lines—right off the bat. Over the long term a healthier codebase leads to more stability and fewer bugs.

It’s not clear how much Chromium-specific code WebKit will be able to remove, but it’s certainly quite a large amount. The above paragraph from Google applies to both parties: at least in terms of efficiency, this is a good thing. Whether the Web will end up benefiting in the long term remains to be seen.
