* layout: Refactor `Flow::from_fragment`-style constructors to bePatrick Walton2016-10-261-1/+1
| | | | consistent.
* Simplify stacking context collectionMartin Robinson2016-09-271-6/+2
| | | | | | | | | | Simplify the way that stacking contexts are collected. Instead of passing the StackingContextId down the tree, pass the parent StackingContext itself. This will allow future patches to get more information about the parent stacking context (such as location). Also remove the return value of collect_stacking_contexts, which was unused.

* script: Keep the DOM-side viewport up to date when scrolling happens inPatrick Walton2016-05-311-1/+2
| | | | | | | | | | | | | | | WebRender. This happens asynchronously, just as it does in non-WebRender mode. This functionality is a prerequisite for doing proper display-list-based hit testing in WebRender, since it moves the scroll offsets into Servo (and, specifically, into the script thread, enabling iframe event forwarding) instead of keeping them private to WebRender. Requires servo/webrender_traits#55 and servo/webrender#277. Partially addresses #11108.

* layout: Rewrite the block formatting context/float inline-sizePatrick Walton2016-03-251-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | speculation code. The old code tried to do the speculation as a single bottom-up pass after intrinsic inline-size calculation, which was unable to handle cases like this: <div> <div style="float: left">Foo</div> </div> <div> <div style="overflow: hidden">Bar</div> </div> No single bottom-up pass could possibly handle this case, because the inline-size of the float flowing out of the "Foo" block could never make it down to the "Bar" block, where it is needed for speculation. On the pages I tried, this regresses layout performance by 1%-2%. I first noticed this breaking some pages, like the Google SERPs, several months ago.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Flatten display list structure Instead of producing a tree of stacking contexts, display list generation now produces a flat list of display items and a tree of stacking contexts. This will eventually allow display list construction to produce and modify WebRender vertex buffers directly, removing the overhead of display list conversion. This change also moves layerization of the display list to the paint thread, since it isn't currently useful for WebRender. To accomplish this, display list generation now takes three passes of the flow tree: 1. Calculation of absolute positions. 2. Collection of a tree of stacking contexts. 3. Creation of a list of display items. After collection of display items, they are sorted based upon the index of their parent stacking contexts and their position in CSS 2.1 Appendeix E stacking order. This is a big change, but it actually simplifies display list generation. <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.svg" height="40" alt="Review on Reviewable"/>](https://reviewable.io/reviews/servo/servo/9756) <!-- Reviewable:end -->

* | Fix border collapsing at the end of a table-row-groupMatt Brubeck2016-03-011-127/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the border-end calculation for table rows whose borders are collapsed with rows in different rowgroups. The border collapsing code now uses an iterator that yields all the rows as a flat sequence, regardless of how they are grouped in rowgroups. It gets rid of `TableRowGroupFlow::preliminary_collapsed_borders` which was never correct. (It was read but never written.) This may fix #8120 but I'm not 100% certain. (I haven't managed to reproduce the intermittent failure locally, and my reduced test case still fails but in a different way.)
* | Fix confusing `push_or_mutate` APIMatt Brubeck2016-02-291-6/+7
|/ | | | | | | | | | This fixes a bug when recalculating border collapsing for an existing table now. The bug was caused by using `push_or_mutate` which has no effect if there is already a value at the specified index. The fix switches incorrect `push_or_mutate` calls to use `push_or_set` instead. It also renames `push_or_mutate` to `get_mut_or_push` which I think is a less-confusing name for this method.

* Improve readability of flow tree dumpMartin Robinson2015-11-231-0/+5

* | layout: Make overflow calculation take relative percentages intoPatrick Walton2015-08-311-3/+13
|/ | | | | | | | | | | | | | | | account. This necessitated changing overflow to be calculated by the parent flow if relatively positioned children are present. That is because the overflow regions cannot be calculated without knowing relative offsets, which themselves cannot be calculated without knowing the parent size (because of percentages). To accomplish this without sacrificing parallelism in the non-relative case, this patch splits overflow into "early" and "late" computation. Late overflow computation cannot be parallelized across children, while early overflow computation can. Makes the "Apple Music" text show up over the full-bleed promotional background on apple.com.

| | | | | | | There is no need to compute next_collapsed_borders_in_block_direction for all kind of flows when it's used only in the table row case. That also avoids a panic when the next child is a table colgroup (this should not happen when iterating over a table row).
