In-progress bugfixes

• SadEagle:bug #169988 --- focus/blur on all elements, head/body parsing #?????, multiple problems with onchange (bug #170451, many others)
  • onchange on lineedit/textarea isn't called because handleFocusOut isn't called for redirected widgets
    • would something like http://rafb.net/p/ikWvHK97.html do? I didn't actually tested the patch for lack of a testcase though.(Sp.)
      • seem to work fine so I'll go ahead... (Sp.)
• working on integrating changes in 4.1.2 ChangeLog (Sp.)
  • Woops, done that already. Sorry. -Maks.
    • bah, nevermind... I'm too slow. Thank you.(Sp.)
• need to add/update several testcases in regression suite for 4 or 5 five bug fixes (Sp.)

Potentially high-impact bugs

• Selection crashes, affecting at least Kopete bug #170749, seen elsewhere, too (I believe I fixed this some times ago.. r855319 bug #167239 - needs test (Spart))
• derstandard.at
• tokenizer script-recursion crashes - (what bug #? (Spart))
  • Might not be a good name, but I mean: bug #170185, part of bug #165601, part of bug #162498, later bts and dupes of bug #145666, and likely some others. My initial description is probably wrong, though --- the problem is the hack in handling window.document that creates the document by calling begin/write/end is doing so on a document with a parser active; one of the triggers is probably because the restoration of frames from KHTMLPageCache may happen in the wrong order, but the various reports suggest it's not the only case. (The reason for the original description is that I recalled seeing quite a few reports mentioning the same m_scriptExecuting assert, e.g. bug #118104 for a long time, and figured it's time to get rid of this; some of those are actually mixed in with the dupes of the above). -S.E.
• QWidget::scroll bug (bug #167739) - ouch, I just discovered the BR and the analysis... that explain why the performance was so low on random pages. Need to use QWidget::scroll with a rect argument on Scrollarea's widget(), but also need to fix the associated Qt bug/inefficiency - doing that now (S.)
  • solved - will prepare a qt-copy patch
• Sometimes changing pages doesn't repaint properly, leaving parts of the old one. I've seen it on lists.kde.org, but can't reproduce now , here is one reproducible (r855004 on branch)testcase, though (but this one uses frames, not standalone) (-S.E.):
  • 1. Go to http://www.cs.cornell.edu/courses/cs3810/2008fa/
  • 2. Click on Grading/HW
  • 3. Scroll down.
  • 4. Click on Grading/HW again -- much of the frame isn't repainted
