* style: Unify Gecko and Servo EventState/ElementState bitsEmilio Cobos Álvarez2023-10-021-3/+3
| | | | | | | | | | | | | | | | Add a dom/base/rust crate called just "dom" where we can share these. Most of the changes are automatic: s/mozilla::EventStates/mozilla::dom::ElementState/ s/EventStates/ElementState/ s/NS_EVENT_STATE_/ElementState::/ s/NS_DOCUMENT_STATE_/DocumentState::/ And so on. This requires a new cbindgen version to avoid ugly casts for large shifts. Differential Revision: https://phabricator.services.mozilla.com/D148537

* style: Allow matches() / querySelector() / etc on chrome docs to access ↵Emilio Cobos Álvarez2023-06-091-6/+7
| | | | | | | | | | | | | | | | | | chrome-only selectors. r=boris Without this some tests fail with the previous patch because code like: https://searchfox.org/mozilla-central/rev/267682a8f45221bf0bfe999d4a0239706a43bc56/browser/base/content/browser-gestureSupport.js#651 starts throwing. Unfortunately I had missed that on my try run, because the error message didn't include that exception (it seemed like an intermittent browser-chrome failure instead). We could expose a ChromeOnly API for this, but this seems better. This fixes it trivially, and also removes the "no url data" situation from the selector parser, which is nice.

* style: Share CascadeData instances across ShadowRootsOriol Brufau2023-05-161-1/+1
| | | | | | | | | | | This should be both a memory and speed win for pages using a lot of Shadow DOM. In order to make the cache properly work we need to start keying media query results on the actual StyleSheetContents, as that's what we share on Gecko, but that should all be fine.

* Replace all uses of the `heapsize` crate with `malloc_size_of`.Nicholas Nethercote2017-10-181-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Servo currently uses `heapsize`, but Stylo/Gecko use `malloc_size_of`. `malloc_size_of` is better -- it handles various cases that `heapsize` does not -- so this patch changes Servo to use `malloc_size_of`. This patch makes the following changes to the `malloc_size_of` crate. - Adds `MallocSizeOf` trait implementations for numerous types, some built-in (e.g. `VecDeque`), some external and Servo-only (e.g. `string_cache`). - Makes `enclosing_size_of_op` optional, because vanilla jemalloc doesn't support that operation. - For `HashSet`/`HashMap`, falls back to a computed estimate when `enclosing_size_of_op` isn't available. - Adds an extern "C" `malloc_size_of` function that does the actual heap measurement; this is based on the same functions from the `heapsize` crate. This patch makes the following changes elsewhere. - Converts all the uses of `heapsize` to instead use `malloc_size_of`. - Disables the "heapsize"/"heap_size" feature for the external crates that provide it. - Removes the `HeapSizeOf` implementation from `hashglobe`. - Adds `ignore` annotations to a few `Rc`/`Arc`, because `malloc_size_of` doesn't derive those types, unlike `heapsize`.

| | | | | | | | | | | | | | | | ServoStyleSetSizes now has two uses, one for the Stylist, and one for the UA cache, and so the patch removes 'Stylist' from the field names.

| | | | | | | | | | The only reason why we had the `existing_style_for_style_damage` bit is to apply some optimizations that we don't have anymore. I still want to reintroduce a few of them, at least for the non-eager pseudo-element case... But I think I won't need this at all. This allows us to remove a fair amount of Gecko code too.

| | | | | | | | | | | The motivation is that Chrome XBL stylesheets can be parsed under author level, but we allow some event-state pseudo classes like :-moz-handled-clicktoplay to be used.

* Look for relevant links while matchingJ. Ryan Stinnett2017-05-241-3/+0
| | | | | | | | | | | | | | | | | Adjust the matching process to look for a "relevant link" while matching. A "relevant link" is the element being matched if it is a link or the nearest ancestor link. Matching for links now depends on the `VisitedHandlingMode`, which determines whether all links match as if they are unvisited (the default) or if the relevant link matches as visited (and all others remain unvisited). If a relevant link is ever found for any selector, track this as part of the `MatchingContext` object. This is used in the next patch to determine if an additional match and cascade should be performed to compute the styles when visited. MozReview-Commit-ID: 3xUbRo7vpuD
* style: Refactor the cascade function.Emilio Cobos Álvarez2017-05-171-1/+1

* Make Restyle tracking more granular.Bobby Holley2016-12-091-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | The primary idea of this patch is to ditch the rigid enum of Previous/Current styles, and replace it with a series of indicators for the various types of work that needs to be performed (expanding snapshots, rematching, recascading, and damage processing). This loses us a little bit of sanity checking (since the up-to-date-ness of our style is no longer baked into the type system), but gives us a lot more flexibility that we'll need going forward (especially when we separate matching from cascading). We also eliminate get_styling_mode in favor of a method on the traversal. This patch does a few other things as ridealongs: * Temporarily eliminates the handling for transfering ownership of styles to the frame. We'll need this again at some point, but for now it's causing too much complexity for a half-implemented feature. * Ditches TRestyleDamage, which is no longer necessary post-crate-merge, and is a constant source of compilation failures from either needing to be imported or being unnecessarily imported (which varies between gecko and servo). * Expands Snapshots for the traversal root, which was missing before. * Fixes up the skip_root stuff to avoid visiting the skipped root. * Unifies parallel traversal and avoids spawning for a single work item. * Adds an explicit pre_traverse step do any pre-processing and determine whether we need to traverse at all.
