The Chromium and WebKit teams checked in a grand total of 1,496 changesets over the past 168 hours. Highlights include the availability for the Web Audio API on all platforms, script de-obfuscation in Web Inspector and a slightly updated user interface for Chrome 12.
Following the availability of the Web Audio API on Mac OS X, Kenneth Russell flipped the switch for branded Windows builds, after which Chris Rogers landed a patch making it work on Linux. If you’re on Windows, get yourself a Chrome Canary build, launch it with the “--enable-webaudio” flag and check out some examples! The commit has been reverted, but work is on its way to get the API back in.
The Web Inspector team has made some great commits again. Firstly, obfuscated source-code (such as a minimized jQuery) may now be cleaned up in the Script Panel by right-clicking on the content and selecting the de-obfuscate option. Undo and redo has been implemented for the text editor, accidentally switching panels during live editing using certain shortcuts has been fixed and the resources panel can now display raw HTTP-headers. Finally, early steps have been taken to move the Detailed Heap Snapshots processing into workers.
One of the problems the prefetch relation for <link>-elements has, is that the linked file will be loaded in WebKit at a very low priority. In order to offer authors a way to preload resources which will be used on the current page, Gavin Peters has implemented the “subresource” relation.
As for specification compliance, a regression related to the ACID3 test has been fixed meaning that it will render pixel-perfect again. The Blob’s slice method has been renamed to Blob.webkitSlice, while also having its semantics change to mimic Array.slice. Simon Fraser has begun with improving WebKit’s border mechanisms, initially by improving the logic used to compute the inner radii on curved borders. Stay tuned..
WebKit’s Content-Security-Policy is now aware of the “self” source and will block string arguments to setTimeout and setInterval unless the “eval-script” option has been set, as they would evaluate the string internally. It is now also possible to define what sources media elements can load from, using the media-src directive.
