[webkit-dev] known gtk+ leaks
Hello. I use a bit old revision of Gtk+ WebKit port (38403) and as I observe my WebKit process, the RSS memory usage rapidly gets bigger and bigger as I browse pages. Because of few modifications I made that work only on older revisions, I can't use the new ones (the modifications are rather small and I don't do any allocation). This can't be the cache as I switch only between two linked pages. This behavior indicates that there was a leak. I've googled and found that there were leaks in libcurl and pango text rendering and want to backport the leak fixes. Could please someone with this knowledge have some spare time and help me find the patches so I can backport the leak fixes.

[webkit-dev] Default keyboard shortcuts for WebKit
I recently made a patch for wxWebKit's keyboard shortcuts (https://bugs.webkit.org/show_bug.cgi?id=24797) where I found it very useful to steal almost the entirety of the windows port's method of doing things. On review it was noted that it may be good if it was moved into Editor, at least because it could then be shared between wx and win, but also to provide a default handling for any ports that might not want to have the incredible switch statements found in gtk and qt. Does anyone see any problems with doing something like this? ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev

Hi all I have a problem, and I don't understand it ,could you tell me ? In the input-element, "." takes the place of "Hello", but I don't know how to do it through C++ functions.

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.

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] 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?

What you describe doesn't sound obviously wrong to me; transforms on CSS-rendered elements are rare and likely to be on only a few elements when used, whereas they are quite common for SVG renderers. To fix these bugs I will need to sorta "hack" how things like outline drawing are done, focus ring invalidation, and repaint rect calculation to take transforms into account inside the renderers. It might be easier to give useful feedback if you give examples of alternate ways to fix particular bugs.

[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.
