Acid3 Test Failures of KHTML
This is an overview of the remaing failures of KHTML on the Acid3 test.
Test No | Area | Diagnosis | Comment | passes in FF3b5 |
---|---|---|---|---|
04 | HTML Parser | Parser bug: iframe missing text kid | discard_until = ID_IFRAME+ID_CLOSE_TAG --- added in http://lists.kde.org/?l=kde-commits&m=99906936412933&w=2. | No |
13 | DOM Range | Unhandled mutation | Yes | |
18 | ???? | ???? | Yes | |
26/27 | JS + DOM Memory management | Cycle breaking cleaning up too much | Yes, but slow | |
29 | HTML Parser | Parser bug: table missing whitespace kid | Yes | |
35 | CSS | getComputedStyle() on <head> (no renderer) | Yes | |
38 | CSS | Lack of restyle | "adding text to a text node didn't make the element non-:empty" | No |
41 | CSS | getComputedStyle() on something else rendererless | Yes | |
43 | Checkboxes, value, attributes | Yes | ||
44 | ???? | ???? | Yes | |
48 (red linktest failed) | CSS | :visited doesn't match relative URL right | Performance critical, hot on things like Qt docs, and already slow | Yes |
51 | DOM2 Table | Stray row | Buggy test. Raised with Ian Hickson. | Yes |
53 | DOM2 Forms | Not managing form's element collection when not in document. | Yes | |
65/69 | Part loading | onload events not emitted for many objects | Yes, after several attempts | |
70-80 | Can't run due to 65/69 | SVG, SMIL + XHTML | No | |
89 | JS RegExp | Lacking syntax check | Perl-centric PCRE behavior. Author promised JS-mode. | Yes |
90 | JS RegExp | References | Perl-centric PCRE behavior. Author promised JS-mode.
(was it ever considered to use Boost.Regex engine instead ? it claims to be using strict ECMA syntax as per http://boost.org/doc/libs/1_35_0/libs/regex/doc/html/boost_regex/ref/syntax_option_type/syntax_option_type_perl.html Update: I tried to build a test application with Boost.Regex 1.33 and it had the same issues than PCRE: /a[])]/ compiled and /(\3)(\1)(a)/ went back as "Invalid Back Reference". -gg Seems that despite the name, it's not really ES compatible --- if the docs are right, it doesn't support \u. |
Yes |
98 | XHTML | createDocument() | Missing view. See proposed patch | No |

These are not meant for commit, but more as a proof of analysis, and starting point for proper fix:
#16, red cat.
Ugly, but roughly correct.

This one just shows that the analysis is correct. It's incorrect (no inheritance), and inefficient.
