| * Restart selector matching from an appropriate compound selectorYusuke Suzuki2014-04-051-12/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introducing 3 matching failure statuses, NotMatchedAndRestartFromClosestLaterSibling NotMatchedAndRestartFromClosestDescendant NotMatchedGlobally When NotMatchedGlobally appears, stop selector matching completely since the succeeding selector never matches. It is raised when Child combinator cannot find the candidate element Descendant combinator cannot find the candidate element When NotMatchedAndRestartFromClosestDescendant appears, the selector matching does backtracking and restarts from the closest Descendant combinator. It is raised when NextSibling combinator cannot find the candidate element. LaterSibling combinator cannot find the candidate element. Child combinator doesn't match on the found element. When NotMatchedAndRestartFromClosestLaterSibling appears, the selector matching does backtracking and restarts from the closest LaterSibling combinator. It is raised when NextSibling combinator doesn't match on the found element. For example, when the selector "d1 d2 a" is provided and we cannot *find* an appropriate ancestor node for "d1", this selector matching raises NotMatchedGlobally since even if "d2" is moved to more upper node, the candidates for "d1" becomes less than before and d1 . The next example is siblings. When the selector "b1 + b2 ~ d1 a" is providied and we cannot *find* an appropriate brother node for b1, the selector matching raises NotMatchedAndRestartFromClosestDescendant. The selectors ("b1 + b2 ~") doesn't match and matching restart from "d1". The additional example is child and sibling. When the selector "b1 + c1 > b2 ~ d1 a" is provided and the selector "b1" doesn't match on the element, this "b1" raises NotMatchedAndRestartFromClosestLaterSibling. However since the selector "c1" raises NotMatchedAndRestartFromClosestDescendant. So the selector "b1 + c1 > b2 ~ " doesn't match and restart matching from "d1".
* | Computed value of 'height: <percentage>' is 'auto' in some cases.Simon Sapin2014-04-032-3/+25
| | | | | | | | | | | | | | | | | | See http://dev.w3.org/csswg/css2/visudet.html#propdef-height This is necessary but not sufficient for #2029. A bug fix in the previous commit "broke" Acid 2 because that bug was hiding this one. This makes Acid 2 pass again.

| | | | | | | | | | | | * Expand the apply() and apply_cached() templates. Their two invocations each were different enough that this improves readability IMO. * Create computed::Context from inherited and cascaded values rather than computed value, as much as possible. * Centralize this creation rather than making it per-property, making 'needed_for_context' not needed anymore. * Pass a context to cascade_with_cached_declarations() rather than duplicate the creation code.

* layout: Aggressively try to share styles with the last few nodes seen.Patrick Walton2014-02-142-57/+179
| | | | | | | This roughly implements the same cache found in Blink. 50% improvement on the rainbow page, but at the cost of reducing parallel gains down to nothing. I added a new page, `perf-rainbow-hard.html`, which disables the optimizations in both Blink and Servo.
