Does ENABLE_XPATH work?
by Paul Pedriana 05 Aug '08

05 Aug '08

If I use '#define ENABLE_XPATH 0' in my config, the build mostly compiles, but not entirely. I get the errors shown below. The compile errors appear to occur because the code below doesn't check for ENABLE(XPATH) (whereas much of the rest of the source code does). Is this an oversight, or am I not understanding something about ENABLE_XPATH? Note: my build is about five weeks old now, and I admit that I don't know how it is that XPATH is used within WebKit.

Hi All We are trying to test javascriptcore using the scripts that we have in Dir \WebKit\WebKitTools\Scripts. We have build the webkit on Symbian UIQ. when we try running a script "run-javascriptcore-tests" from command prompt it gives some errors as follows The system cannot find the path specified. The system cannot find the path specified. Building not defined for this platform! Compiling testkjs failed! Is there any thing more needed to make these scripts run. We tried it on Cygwin also still the same errors. Thanks Varun

WebCore uses it quite heavily. Why not use it? It uses the platform's native threading APIs (gthread on glib, QThread on Qt, pthread on OS X, Win32 threads on Win32) >_______________________________________________ >webkit-dev mailing list >webkit-dev(a)lists.webkit.org >http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev -- Justin Haygood jhaygood(a)reaktix.com Reaktix.

WebKit/GTK+ and N810
by Afonso Costa 01 Aug '08

01 Aug '08

Hi all, I'd like to do some tests using WebKit/GTK+ in my N810. I've built it using some information listed here [1] and here [2]. Fortunately I got to build it in my Scratchbox environment and I've installed it in my N810. But when I open http://www.gtk.org in GtkLauncher, for my surprise, I get this result [3]. When I open the same site in my desktop Linux, I can get other different result [4]. It's missing a blue background... Am I missing anything in my build process? Is there other patch related to ARM? I'm configuring WebKit with: configure --enable-video --with-hildon. I've already tested it with --disable-xslt, but I didn't get any success. My scratchbox environment is: Chinook - cs2005q3.2-glibc2.5-arm #gcc --version: sbox-arm-linux-gcc (GCC) 3.4.4 (release) (CodeSourcery ARM 2005q3-2) Thanks in advance.

WindScorpion
by Zoltan Herczeg 01 Aug '08

01 Aug '08

Dear Webkit Developers, We have extended the SunSpider benchmark system with some new JavaScript benchmarks. These JS examples are collected from the Internet and they are freely available. Its name is WindScorpion, which is another name of SunSpider. You can download it from: http://www.inf.u-szeged.hu/opensource/download/get.php?name=WindScorpion.tgz To use it, simply copy them the the SunSpider/tests directory, and extend the LIST file with the names. The individual test cases are designed to run around 2 seconds, but this time increases when you put them under SunSpider. Besides from the benchmark, we are also made some coverity tests. (It seems your automated coverity measurement site is down for some time). The mozilla regression tests (JavaScriptCore/tests) are also included as they are good for reference. * gcc (function coverage) * there are 2034 functions in the jsc binary * Num of functions covered by sunspider: 998 * Num of functions covered by windscorpion: 940 * Num of functions covered by regression test: 1406 * Num of functions covered by sunspider but not covered by windscorpion: 142 * Num of functions covered by sunspider but not covered by regression test: 2 * Num of functions covered by windscorpion but not covered by sunspider: 84 * Num of functions covered by windscorpion but not covered by regression test: 3 * Num of functions covered by regression test but not covered by sunspider: 410 * Num of functions covered by regression test but not covered by windscorpion: 469 * gcc (AST node coverage) * there are 77 node types in the jsc binary * Num of node types covered by sunspider: 55 * Num of node types covered by windscorpion: 63 * Num of node types covered by regression test: 71 * Num of node types covered by sunspider but not covered by windscorpion: 5 * Num of node types covered by sunspider but not covered by regression test: 0 * Num of node types covered by windscorpion but not covered by sunspider: 13 * Num of node types covered by windscorpion but not covered by regression test: 1 * Num of node types covered by regression test but not covered by sunspider: 16 * Num of node types covered by regression test but not covered by windscorpion: 9 Two of the WindScorpion tests are not included in the package, because they have a strange behaviour when used under SunSpider. * randPrime.js - the runtime is somehow increased to 16 seconds from 2 * wordreplace.js - the runtime is "undefined", if all wind scorpion benchmarks are included in the LIST. However, it is working, if this file is appended alone to the end of the LIST file. We plan to investigate them later. If you wish, you can extend SunSpider with some of them. Cheers, Zoltan
