This part should not be needed.  We're missing some non-svg properties from this list which are being masked by the presence of applySVGProperty. :(

I'm not saying it's your fault.  But the build break for non-svg is just being masked in teh SVG case, and is a real bug.
Comment 11 Antti Koivisto 2013-01-25 10:00:35 PST
I would be nice to get rid of the no-SVG build entirely. I guess everyone ships it.
Comment 12 Eric Seidel (no email) 2013-01-25 10:02:59 PST
before SVG came along, all CSS properties were handled in applyProperty().  For various reasons, SVG property handling was made separate in svgApplyProperty, but they share in enum, thus we had to add that default: clause.  Now, since SVG has been enabled for so long, someone must have added a new proprty and failed to support it in applyProperty like they should.  We didn't catch it, because both applyProperty and applySVGPrperty use default: clauses since neither of them can handle the whole list of properties in their switch. :(

I agree with you guys. The correct way for the switch should be:

case <a non-svg case>:
 blah-blah;
#if ENABLE(SVG)
case <a svg case>:
 blah-blah;
#endif
default:
 assert(0);

But my fix at least didn't introduce new bugs. :) I just wanted to commit it so I don't have to patch it every time. Thanks.
