* Rename `gfx` to `fonts` (#32556)Martin Robinson2024-06-197-13/+14
| | | | | | | | | This crate only takes care of fonts now as graphics related things are split into other crates. In addition, this exposes data structures at the top of the crate, hiding the implementation details and making it simpler to import them.

* base: Remove `ucd` dependency (#32424)Martin Robinson2024-06-032-4/+5
| | | | | | | | | | | | | | Remove the `ucd` dependency which has not been updated in 8 years. In addition, replace it with a generated UnicodeBlock enum which reflects the modern Unicode standard. This is generated via a Python script which is included in the repository. The generation is not part of the build process, because the Unicode database is hosted on the web and it does not change the frequently. This is done instead of bringing in the more up-to-date `unicode_blocks` dependency. `unicode_blocks` defines each block as constant, which means that they cannot be used in match statements -- which we do in Servo.

* layout: Add support for `white-space-collapse: break-spaces` (#32388)Martin Robinson2024-05-307-9/+636
| | | | | | | | | | | | | | This change adds support for `white-space-collapse: break-spaces` and adds initial parsing support for `overflow-wrap` and `word-break`. The later two properties are not fully supported, only in their interaction with `break-spaces`. This is a preliminary change preparing to implement them. In addition, `break_and_shape` is now forked and added to Layout 2020. This function is going to change a lot soon and forking is preparation for this. More code that is only used by Layout 2013 is moved from `gfx` to that crate. Co-authored-by: Rakhi Sharma <atbrakhi@igalia.com>

* fonts: Improve font fallback (#32286)Martin Robinson2024-05-271-4/+5
| | | | | | | | | | | | | | | | | | - Better detect situations where emoji is necessary by looking ahead one character while laying out. This allow processing Unicode presentation selectors. When detecting emoji, put emoji fonts at the front of fallback lists for all platforms. This enables monochrome emoji on Windows. Full-color emoji on Windows probably needs full support for processing the COLR table and drawing separate glyph color layers. - Improve the font fallback list on FreeType platforms. Ideally, Servo would be able to look through the entire font list to find the best font for a certain character, but until that time we can make sure the font list contains the "Noto Sans" fonts which cover most situations. Fixes #31664. Fixes #12944.
* compositor: Move WebRender-ish messages and types to `webrender_traits` (#32315)Mukilan Thiyagarajan2024-05-205-7/+9
| | | | | | | | | | | | | | | | | | | | * Move WebRender related types to `webrender_traits` This refactor moves several WebRender related types from `compositing_traits`, `script_traits` and `net_traits` crates to the `webrender_traits` crate. This change also moves the `Image` type and associated function out of `net_traits` and into the `pixels` crate.

* Move non-gfx things out of `gfx_traits` and create a `base` crate (#32296)Martin Robinson2024-05-1717-24/+51
| | | | | | | | | | | | | | | | | | | | | | | For a long time, `gfx_traits` has held a lot of things unrelated to graphics and also unrelated to the `gfx` crate (which is mostly about fonts). This is a cleanup which does a few things: 1. Move non `gfx` crate things out of `gfx_traits`. This is important in order to prevent dependency cycles with a different integration between layout, script, and fonts. 2. Rename the `msg` crate to `base`. It didn't really contain anything to do with messages and instead mostly holds ids, which are used across many different crates in Servo. This new crate will hold the *rare* data types that are widely used. Details: - All BackgroundHangMonitor-related things from base to a new `background_hang_monitor_api` crate. - Moved `TraversalDirection` to `script_traits` - Moved `Epoch`-related things from `gfx_traits` to `base`. - Moved `PrintTree` to base. This should be widely useful in Servo. - Moved `WebrenderApi` from `base` to `webrender_traits` and renamed it to `WebRenderFontApi`.
* fonts: Make `FontContext` thread-safe and share it per-Layout (#32205)Martin Robinson2024-05-027-87/+47
| | | | | | | | | | | | This allows sharing font templates, fonts, and platform fonts across layout threads. It's the first step toward storing web fonts in the layout versus the shared `FontCacheThread`. Now fonts and font groups have some locking (especially on FreeType), which will probably affect performance. On the other hand, we measured memory usage and this saves roughly 40 megabytes of memory when loading servo.org based on data from the memory profiler.

* Turn white-space into a shorthand (#32146)Oriol Brufau2024-04-293-28/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | Bumps Stylo to servo/stylo#37 `white-space` is split into `white-space-collapse` and `text-wrap-mode`: | white-space | white-space-collapse | text-wrap-mode | | ----------- | -------------------- | -------------- | | normal | collapse | wrap | | nowrap | collapse | nowrap | | pre-wrap | preserve | wrap | | pre | preserve | nowrap | | pre-line | preserve-breaks | wrap | | - | preserve-breaks | nowrap | Note this introduces a combination that wasn't previously possible, but I think the existing logic can handle it well enough. The old `allow_wrap()` is replaced by checking whether `text-wrap-mode` is set to `wrap`. The old `preserve_newlines()` is replaced by checking whether `white-space-collapse` is *not* set to `collapse`. The old `preserve_spaces()` is replaced by checking whether `white-space-collapse` is set to `preserve`.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes changes to allow Servo to compile with the 1.78 version of Rust: - Dead code is removd (Rust seems to have gotten better at detecting it). - The `FlowRef` `DerefMut` is updated according to @SimonSapin's advice [^1]. - The `imports.rs` now explicitly silences warnings about unused imports.

* chore: Clean up use of `gfx` and `constellation` types (#31981)Martin Robinson2024-04-093-15/+4
| | | | | | | | | | | | This change contains three semi-related clean ups: 1. the `to_webrender()` and `from_webrender()` functions on Pipeline are turned into more-idiomatic `From` and `Into` implementations. 2. `combine_id_with_fragment_type` now returns a `u64` as that is what is expected for all callers and not a `usize`. 3. The `query_scroll_id` query is removed entirely. The `ExternalScrollId` that this queries is easily generated directly from the node's opaque id. Querying into layout isn't necessary at all.
* script: Split style and layout data in DOM nodes (#31985)Martin Robinson2024-04-045-92/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change splits the style and layout data in DOM nodes that is populated by style and layout passes. This makes Servo's data design more like Gecko's. This allows: 1. Removing the various `StyleAndLayout` data structures used by layout. 2. Removing the `GetStyleAndLayoutData` and `GetStyleAndOpaqueLayoutData` traits. Accessing style and layout data are now just functions on the `LayoutNode` and `ThreadSafeLayoutNode` traits. 3. Styling now doesn't populate layout data. This is is postponed until layout itself. 4. Allows the DOM wrappers to no longer have to be generic over the layout data. This data was already stored using `std::any::Any` and the new code just makes layout responsible for downcasting. Cleaning up the generic type parameter in the DOM wrappers can happen in a followup change. The main benefit to all of this is that we should be able to remove unsafe creation of `ServoLayoutNode` in layout and `TrustedLayoutNodeAddress` entirely, because `ServoLayoutNode` will be able to be passed directly from script to layout. In addition, this removes one more abstraction layer from the layout DOM wrappers, making the code a lot more understandable. Note: This increases the measured size of DOM types, but the same data is stored. It's simply that before that data was stored behind a heap pointer.
* script: Reduce the use of `unsafe` in LayoutDom (#31979)Martin Robinson2024-04-031-1/+1
| | | | | | | | | | | | | Remove the use of unsafe code in the layout wrappers of the DOM. The main change here is that `unsafe_get()` no longer needs to be an unsafe method, which allows us to transitively remove or reduce unsafe blocks from callers. The function itself is not renamed, because it's still a bit dangerous to start removing the layers of abstraction from actual DOM nodes. In addition `init_style_and_opaque_layout_data` can be merged into `initialize_data`, which removes one more unsafe method. Finally, a "Safety" section is added to some unsafe methods.

* layout: Remove LayoutRPC and query layout via the `Layout` trait (#31937)Martin Robinson2024-03-291-174/+16
| | | | | | | | | | | | | | | | | Instead of the tricky `LayoutRPC` interface, query layout using the `Layout` trait. This means that now queries will requires calling layout and then running the query. During layout an enum is used to indicate what kind of layout is necessary. This change also removes the mutex-locked `rw_data` from both layout threads. It's no longer necessary since layout runs synchronously. The one downside here is that for resolved style queries, we now have to create two StyleContexts. One for layout and one for the query itself. The creation of this context should not be very expensive though. `LayoutRPC` used to be necessary because layout used to run asynchronously from script, but that no longer happens. With this change, it becomes possible to safely pass nodes to layout from script -- a cleanup that can happen in a followup change.

* dependencies: Upgrade to WebRender 0.64 (#31486)Martin Robinson2024-03-145-80/+132
| | | | | | | | | This brings the version of WebRender used in Servo up-to-date with Gecko upstream. The big change here is that HiDPI is no longer handled via WebRender. Instead this happens via a scale applied to the root layer in the compositor. In addition to this change, various changes are made to Servo to adapt to the new WebRender API.

* fonts: Add `FontIdentifier` and `LocalFontIdentifier` (#31658)Martin Robinson2024-03-141-3/+3
| | | | | | | | | | | | | | | | | | | Instead of using a simple `Atom` to identify a local font, use a data structure. This allows us to carry more information necessary to identify a local font (such as a path on MacOS). We need this for the new version of WebRender, as fonts on MacOS now require a path. This has a lot of benefits: 1. We can avoid loading fonts without paths on MacOS, which should avoid a lot of problems with flakiness and ensure we always load the same font for a given identifier. 2. This clarifies the difference between web fonts and local fonts, though there is more work to do here. 3. This avoid a *lot* of font shenanigans, such as trying to work backwards from the name of the font to the path of the font we actually matched. In general, we can remove a lot of code trying to accomplish these shenanigans. 4. Getting the font bytes always returns an `Arc` now avoiding an extra full font copy in the case of Canvas.
* layout: Propagate overflow values from `<body>` to root element (#31618)Martin Robinson2024-03-131-1/+7

* layout: Enable rendering of `conical-gradient` and ↵Martin Robinson2024-03-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | `repeating-conical-gradient` (#31597) This also ignores a clippy warning for a new function (and a similar existing one), until this code can be refactored to use temporary Rust strutures to carry display list building state. There are a few new test failures here: - FAIL [expected PASS] /css/css-images/image-set/image-set-conic-gradient-rendering.html - FAIL [expected PASS] /css/css-images/image-set/image-set-repeating-conic-gradient-rendering.html These fail because Servo does not yet support `image-set()`. - FAIL [expected PASS] /css/filter-effects/filter-function/filter-function-conic-gradient.html - FAIL [expected PASS] /css/filter-effects/filter-function/filter-function-repeating-conic-gradient.html These fail because Servo does not support the very early filter effects specification. - FAIL [expected PASS] /html/canvas/element/manual/fill-and-stroke-styles/conic-gradient-rotation.html - FAIL [expected PASS] /html/canvas/element/manual/fill-and-stroke-styles/conic-gradient.html These fail because this change only adds support for CSS conical gradients. Another set of changes will be necessary to support this for Canvas.

* layout: Turn on synthetic small-caps for layout 2020 (#31435)Martin Robinson2024-02-281-3/+6
| | | | | | | | | | | | Synthetic small caps is supported by the font subsystem, but this is disabled in Layout 2020. We can turn this on to bring support to parity with the old layout system. In addition to turning on synthetic small-caps this change also improves the way that they work. Before, synthetic small caps meant that every character was a small version of capitalized character. After this change, capital letters are larger than small caps versions of small letters -- matching other browsers and the common expectation of how small caps works.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * script: Do not run layout in a thread Instead of spawning a thread for layout that almost always runs synchronously with script, simply run layout in the script thread. This is a resurrection of #28708, taking just the bits that remove the layout thread. It's a complex change and thus is just a first step toward cleaning up the interface between script and layout. Messages are still passed from script to layout via a `process()` method and script proxies some messages to layout from other threads as well. Big changes: 1. Layout is created in the script thread on Document load, thus every live document is guaranteed to have a layout. This isn't completely hidden in the interface, but we can safely `unwrap()` on a Document's layout. 2. Layout configuration is abstracted away into a LayoutConfig struct and the LayoutFactory is a struct passed around by the Constellation. This is to avoid having to monomorphize the entire script thread for each layout. 3. Instead of having the Constellation block on the layout thread to figure out the current epoch and whether there are pending web fonts loading, updates are sent synchronously to the Constellation when rendering to a screenshot. This practically only used by the WPT. A couple tests start to fail, which is probably inevitable since removing the layout thread has introduced timing changes in "exit after load" and screenshot behavior.

* layout: Add support for table rows, columns, rowgroups and colgroups (#31341)Martin Robinson2024-02-201-2/+2
| | | | | | | | | | | | | | This adds support for table rows, columns, rowgroups and colgroups. There are few additions here: 1. The createion of fragments, which allows script queries and hit testing to work properly. These fragments are empty as all cells are still direct descendants of the table fragment. 2. Properly handling size information from tracks and track groups as well as frustrating rules about reordering rowgroups. 3. Painting a background seemlessly across track groups and groups. This is a thing that isn't done in legacy layout (nor WebKit)! Co-authored-by: Oriol Brufau <obrufau@igalia.com>

* Add support for table fixups (#30868)Martin Robinson2023-12-221-2/+2
| | | | | | | | | | | | | | | | This adds support for fixing up tables so that internal table elements that are not properly parented in the DOM have the correct box tree structure according to the CSS Table specification [1]. Note that this only comes into play when building the DOM via script, as HTML 5 has its own table fixups that mean that the box tree construction fixups here are not necessary. There are no tests for this change. In general, it's hard to write tests against the shape of the box tree, because it depends on the DOM. We plan to test this via WPT tests once layout is complete. 1. https://drafts.csswg.org/css-tables/#table-internal-element Co-authored-by: Oriol Brufau <obrufau@igalia.com>

| | | | | | | | | | * Add initial support for sticky positioning for non-legacy layout Many tests still fail for a variety of reasons.

* Move `*_traits` and other shared types to `shared`Martin Robinson2023-11-031-9/+9
| | | | | | | | | | | | This is the start of the organization of types that are in their own crates in order to break dependency cycles between other crates. The idea here is that putting these packages into their own directory is the first step toward cleaning them up. They have grown organically and it is difficult to explain to new folks where to put new shared types. Many of these crates contain more than traits or don't contain traits at all. Notably, `script_traits` isn't touched because it is vendored from Gecko. Eventually this will move to `third_party`.

* Don't panic when no font is found for a TextRun (#30581)Martin Robinson2023-10-191-6/+19
| | | | Instead of panicking when no found is found for a TextRun, instead print a warning. This prevents panics on pages with very large font sizes.
* Anonymous boxes that wrap inlines should not inherit overflow (#30579)Martin Robinson2023-10-191-14/+14
| | | | | | | | | | | | | | In legacy layout, anonymous text wrappers were inheriting the `overflow` and `text-overflow` properties. This results in the creation of extra clipping for these anonymous wrappers which could clip away floats. We will likely implement `text-overflow` differently in non-legacy layout. This change marks all legacy layout pseudo elements as "legacy" and also adds a new pseudo element for non-legacy layout that does not inherit `overflow`. Fixes #30562.
