Acid3 Test Failures of KHTML
This is an overview of the remaing failures of KHTML on the Acid3 test. FF3.1 beta2pre scores 91/100, with 5 of the colored boxes filled in correctly.
| Test No | Area | Diagnosis | Comment | passes in FF3 | passes in FF3.1 |
|---|---|---|---|---|---|
| 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 | Yes |
| 13 | DOM Range | Unhandled mutation | Yes | Yes | |
| 26/27 | JS + DOM Memory management | Cycle breaking cleaning up too much | Yes, but slow | Yes, but slow | |
| 29 | HTML Parser | Parser bug: table missing whitespace kid | Yes | Yes | |
| 40 | CSS Matching | Parsing of n-th-last-of-kind(-5n+3) wrong. | No | ||
| 43 | Likely: radio button groups outside a form | Yes | Yes | ||
| 44 | CSS Parser | Misparse of html*.test selector (see below) | 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 | Yes |
| 51 | DOM2 Table | Stray row | Buggy test. Raised with Ian Hickson. | Yes | Yes |
| 53 | DOM2 Forms | Not managing form's element collection when not in document. | Yes | Yes | |
| 65/69 | Part loading | onload events not emitted for many objects | Yes, after several attempts | 69 fails due to network timeout | |
| 70-80 | Can't run due to 65/69 | SVG, SMIL + XHTML | No | 72, 73, and 80 pass; rest fail |
Note: An upgrade to PCRE 7.7 is required to make tests 89 and 90 pass.
Random patch storage
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.

#48, red linktest failed
It's a bug inside KonqHistoryManager --- it ignores some inserts, which makes the link not :visited. We may still want to consider the diff below, but it'll likely slow things down too much.

7x tests
A lot of the fail due to XSS checks disabling all access to XML. Below fixes it:

#71 testcase
With above, we fail at least the following in #71:
<script>
var doc = document;
doc.open();
doc.write("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\"><title><\/title><span><\/span><script type=\"text/javascript\"><\/script>");
doc.close();
alert(document.childNodes.length);
alert(document.childNodes[0]);
alert(document.childNodes[1]);

This is fixed by below, but integrated test still fails:
