[webkit-dev] Back/forward cache for pages with unload handlers

2009-09-09 Thread Brady Eidson
Since the beginning, WebKit has excluded pages with unload handlers from its back/forward cache. There has been an unspoken assumption for 6 years now that we "have to do it." In recent explorations to improvements we can make to the back/forward cache, we've collected tons of data that su

I guess that might make the fence too tall if something outside of it is taller than what's inside. You may have to just drill into your children line boxes in order to compute your top and your bottom position. We don't really have the concept of caching "line top" and "line bottom" exce

So fencing should extend from the line top to the line bottom it sounds like without affecting the overall height of the line? Have you tried placing them with a y position of the root line box's line top and a height of line bottom - line top? dave On Sep 9, 2009, at 12:39 PM, Alex Milow
