908b9627a2 Track only the number of important declarations in a declaration block 2016-08-22 14:05:09 +02:00

f9150af936 Keep track of the number of important and normal declarations in a block 
… instead of the presence (`bool` flags) of each.

This allows removing `recalc_any` which iterated over the `Vec`.

Rewrite the style sharing candidate cache. 
The style candidate cache had regressed a few times (see #12534), and my
intuition is that being able to disable all style sharing with a single rule in
the page is really unfortunate.

This commit redesigns the style sharing cache in order to be a optimistic cache,
but then reject candidates if they match different sibling-affecting selectors
in the page, for example.

So far the numbers have improved, but not so much as I'd wanted (~10%/20% of
non-incremental restyling time in general). The current implementation is really
dumb though (we recompute and re-match a lot of stuff), so we should be able to
optimise it quite a bit.

I have different ideas for improving it (that may or may not work), apart of the
low-hanging fruit like don't re-matching candidates all the time but I have to
measure the real impact.

Also, I need to verify it against try.

style: Rewrite the restyle hints code to allow different kinds of element snapshots, and use it for Gecko. 
This is a rewrite for how style interfaces with its consumers in order to allow
different representations for an element snapshot.

This also changes the requirements of an element snapshot, requiring them to
only implement MatchAttr, instead of MatchAttrGeneric. This is important for
stylo since implementing MatchAttrGeneric is way more difficult for us given the
atom limitations. This also allows for more performant implementations in the
Gecko side of things.

5c70dfab01 Have a concrete SelectorImpl type everywhere in the style crate. 
It is conditionally compiled to one implementation or the other
(Gecko or Servo) with `#[cfg(…)]`.

style: Support lazy pseudo-elements 
These can't be supported in Servo as of right now, because I'm not
totally sure the accesses that should be done in layout would be
thread-safe.

It can be revisited later though.

6889f37d9e Remove the url! plugin. 
In rust-url 1.0 the `Url` struct is going to have private fields, and there
is no way to to create an aribitrary one without going through the parser.

The plugin never had a clear demonstrated performance benefit,
it was made mostly because it was possible and relatively easy at the time.
