Versioned dom This PR adds versioning to the DOM. There are now node.get_version and node.get_descendent_version methods that return a counter that is bumped when the node is dirtied. This is used to implement cache invalidation for caching HTMLCollection state. Caching HTMCollections gets a 1000x speedup in the Dromaeo DOM query tests. Addresses https://github.com/servo/servo/issues/6901, https://github.com/servo/servo/issues/3381 and https://github.com/servo/servo/issues/1916. Replaces PR https://github.com/servo/servo/pull/6927. <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.png" height=40 alt="Review on Reviewable"/>](https://reviewable.io/reviews/servo/servo/8227) <!-- Reviewable:end --> |
