Bug 8072 – REGRESSION: text fields at connect.apple.com spill out of the containing box

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Henk]

The widths of the textfields "Apple ID" and "Password" are incorrect.

The regression was intruduced starting with nightly r13567

[Darin Adler]

Actually, the widths of the text fields look fine to me (same as before). The problem seems to be the position of the text fields, not the widths.

reduction, showing this is some sort of min/max width issue

[Darin Adler]

I think the bug is caused by the fact that RenderTextField::calcMinMaxWidth sets the min/max width to a width based on the input element's size attribute even when the style has a width specified.

[Darin Adler]

RenderTextField::calcMinMaxWidth is clearly wrong in at least a few ways. For example, it doesn't consider border or padding. It doesn't consider the values of any CSS properties (width, min-width, max-width).

What's annoying is that we probably want most of the logic from RenderBlock::calcMinMaxWidth, but we can't use it because it calls non-virtual calcInlineMinMaxWidth or calcBlockMinMaxWidth. We can look at RenderReplaced::calcMinMaxWidth for inspiration, I guess. Or maybe Hyatt already has a good technique in mind for this.

These are all text field regressions so they should all be P1.

Assigning to Adele since she says she is working on this.

Dave, can you take a look at this first cut of fixing RenderTextField::calcMinMaxWidth?

You shouldn't need these lines at all:

+    calcBlockMinMaxWidth();
+
+    if(m_maxWidth < m_minWidth) m_maxWidth = m_minWidth;

Other than that, I think this is right, although we probably need more tests of non-fixed widths on text fields (i.e., width:100%).
