Resources such as nib files and help files aren't amenable to things like #defines. Filenames and build system metadata fall in to the same cateogry. The source code proper is a different story, but is also trivially updateable via sed or t

While I've not measured the performance of the approaches, from reading the Python patch discussed in the article it would appear that Objective-C uses a more intelligent approach to maintaining the reference count in the face of concurrent

While the WebKit project has a strict review process and a substantial amount of regression testing, code reviews can't catch all issues and WebKit doesn't have complete test coverage for all aspects of web technology. Changes can, and ofte

By replacing your system frameworks with those from a WebKit nightly you're going to see trouble with OS X software updates, system-wide instability due to running bleeding-edge code, and a test environment which isn't representative of wha

I don't see how this explanation can be correct given the fact that the code using host_vmxon / host_vmxoff in the revision you point to is guarded by #if VBOX_WITH_HOST_VMX, which the changeset also shows is false. It wasn't turned on unti

Hmm… it looks like I misspoke. The "sparse mode" check that Array.prototype.sort performs in JavaScriptCore appears to be different than the its concept of sparse array storage, which is used under the conditions I described. The "sparse mo

The version of JavaScriptCore (and the rest of WebKit) available from svn.webkit.org is exactly what is shipped in Safari on OS X.

Can you point me at some code comparing the performance of your JavaScript quicksort implementation to the browser's native sort? I threw together a quick comparison myself and couldn't see any cases where the JavaScript implementation was

This is also fast in Safari because the array isn't sparse enough for JavaScriptCore to send it down the fallback path. EDIT: In order to go down the fallback path the array needs to be both sufficiently large and sufficiently sparse (<

The AVL tree is used for sorting when there is a custom comparison function because we cannot guarantee that the user-provided comparison function conforms to the requirements of the underlying standard library sort functions. Websites have

> A well-designed OS shouldn't require you to keep multiple versions installed on a machine like that. A well-designed OS should require you to install a separate version of Python if the version it provides does not suit your needs.

Upgrading the system Python on Mac OS X isn't easy because it's not something you should do. See http://stackoverflow.com/a/1541850 for something of an explanation about this.

Amusingly enough, Mail’s compose window uses WebKit for the content area. According to http://webkit.org/b/73888 the issue is specific to the WebKit2 layer that is currently used only by Safari.

Yup. It’s really unfortunate. I prefer to opt out of YouTube’s HTML5 mode and use the YouTube5 extension to achieve a similar effect. It also has the added benefit of avoiding the Flash player on videos where YouTube chooses not to use the

Do you have Perian installed? Does http://www.youtube.com/html5 report that Safari supports WebM? If so, then what you’re seeing is YouTube preferring WebM over h.264, even though h.264 decoding is hardware accelerated rather than the sof

That sandbox violation is not coming from your application. WebProcess is the process used for rendering web content in Safari only.

Your post itself was entirely fair, and the improvements to the profiler were great. It is only the title of this posting that I take issue with. If the title had been "280 North makes WebKit's JavaScript Profiler Useful!" I don't think i

We clearly have very different understandings of the term "at all". The "heavy" view in the profiler reported incorrect information when recursive function calls were involved. The default view (top-down) of the profiler worked fine, and t

The title here is completely inaccurate. Francisco Tolmasky fixed a few bugs in WebKit's existing profiler, he did not contribute "a new JavaScript profiler". Many kudos to him for taking the time to fix these issues, but lets keep things
