[webkit-dev] chrooting WebKit
Hi, is there an API to limit the WebKit's access to local resources? What I've been looking for is kind of chroot() inside of WebKit. So a local file loaded e.g from /usr/share/test would only be able to refer to files under /usr/share/test. Currently a file loaded from local disk can refer to anywhere. I've been looking at SecurityOrigin.cpp but it seems that once the file is considered local then it can access any local file.

[webkit-dev] Building QtWebKit on Mac OS X
Hi, I'm trying to build QtWebKit framework on mac os x,, i did finally manage to build but it only built Qluncher and test apps but not QtWebkit framework. i used build-webkit with qt option to build. Is there any option I need to use to build the framework on Mac OS !! Thanks Husam ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] OpenCL
IMO the biggest benefits that OpenCL (or some other vector-savvy multiprocessing interface) could bring to WebKit would be in the following areas: Reading graphics files (e.g. jpg) Encryption/Decryption (TLS, SSL) Compositing graphics in software (e.g. alpha blends) Implementing runtime graphics decompression (e.g. blitting from DXT or RLE or even possibly directly from .jpg/.png) Improving special cases of existing _javascript_ execution Improving video codec performance (for video plugins) I don't see OpenCL easily improving the following areas, though there are ways to throw general threads at these problems: Network transport HTML/XML/CSS parsing Layout / Font processing, at least at the low level General _javascript_ execution, JITing _javascript_ General Flash script execution AJAX related functionality On Windows you can achieve significantly higher network throughput by splitting the work across multiple threads, due to how the network stack works. If you needed to read 100 files from a server, you'd get better performance by splitting it into 4 pipelined HTTP connections on 4 threads. This is true even if you don't have multiple CPUs. It's not easy to parallelize things like text parsing and DOM processing. There's a reason why a lot of multiprocessing research focuses on the success cases of things like DSP, matrix math, and naturally branch-less algorithms. Paul Hi, I wonder if it is planned to rewrite WebKit in OpenCL. I'm not sure but theoretically we could expect a further big improvement in speed, both in rendering HTML and _javascript_. Am I wrong?

Re: [webkit-dev] want to port JIT to MIPS - where comes from _ZN3JSC8JITStubs12cti_vm_throwEPvz
jit complier give error because above label is hard coded. It reports the error with a file .s under /tmp yet I cannot see and not sure who removes it. Pls be kindly to let me know how I can change above label to correct one. Also, now I see hard coded constant patchOffsetOpCallCompareToJump=6 comes from some code via gdb, yet not sure where/when it is generated. It seems to be a c function head. rgds joe ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] chrooting WebKit
There isn't currently an API for doing this. You're right, though, that SecurityOrigin.cpp would be the file that would implement this feature.

[webkit-dev] how to instead of ..... in the password editor
Hi all I have a problem, and I don't understand it ,could you tell me ? input type=password id=text name=text1 value=Hello In the input-element, . takes the place of Hello, but I don't know how to do it through C++ functions. Thank you best regards zhang ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev

Thank you best regards Hey Zhenghe, you have written more than 30 mails starting from December, Have you contributed anything during this time to WebKit.org project (filed a bug, send a patch?)? Where is your interest coming from? z.. ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
