Sam Atkins	79093291b5	LibWeb/CSS: Un-template parse_comma_separated_value_list() ... This doesn't need to be a template. Changing it means we can use it from any FooParsing.cpp file, and also move it ValueParsing.cpp where it belongs.	2025-04-04 10:40:32 +01:00
Sam Atkins	fd4f4f425d	LibWeb: Generate DescriptorID enum ... Add a new JSON file describing at-rule descriptors, and then use it to generate a DescriptorID enum, and code to check if it's accepted in a given at-rule.	2025-04-04 10:40:32 +01:00
Timothy Flynn	a3ea4881e7	LibWeb+LibWebView+UI: Migrate to LibWebView's language settings	2025-04-04 10:16:32 +02:00
Tim Ledbetter	c941170e5a	LibWeb: Invalidate document style when media rules are changed ... This ensures that new media rules are always produce the correct result when evaluated.	2025-04-04 10:10:43 +02:00
Andrew Kaster	9ee2473aa4	LibWeb+LibGC: Import GC swift module into LibWeb and an initial user ... Start work on a speculative HTML Parser in Swift. This component will walk ahead of the normal HTML parser looking for fetch() requests to make while the normal parser is blocked. This work exposed many holes in the Swift C++ interop component, which have been reported upstream.	2025-04-03 16:47:48 -06:00
Andrew Kaster	e4c88915ab	LibGC+LibJS+LibWeb: Add workaround for Swift boolean bitfield issue ... This patch adds a workaround for a Swift issue where boolean bitfields with getters and setters in SWIFT_UNSAFE_REFERENCE types are improperly imported, causing an ICE.	2025-04-03 16:47:48 -06:00
Aliaksandr Kalenik	12a2aebeb6	LibWeb: Move painting surface allocation into rendering thread ... Skia has a check in debug mode to verify that surface is only used within one thread. Before this change we were violating this by allocating surfaces on the main thread while using and destructing them on the rendering thread.	2025-04-03 22:01:43 +02:00
Aliaksandr Kalenik	4b04e97feb	LibWeb: Send IPC messages exceeding socket buffer through shared memory ... It turned out that some web applications want to send fairly large messages to WebWorker through IPC (for example, MapLibre GL sends ~1200KiB), which led to failures (at least on macOS) because buffer size of TransportSocket is limited to 128KiB. This change solves the problem by wrapping messages that exceed socket buffer size into another message that holds wrapped message content in shared memory.

Aliaksandr Kalenik	bc0ec84100	LibWeb: Don't queue rendering task for empty display lists	2025-04-02 23:22:38 +02:00
Aliaksandr Kalenik	cf143cf118	LibWeb: Don't call flush() when no surface is passed in execute_impl() ... `DisplayListPlayer::execute_impl()` can receive null surface if it was invoked to rasterize nested display lists (we use them for iframes). In this case we should not call `flush()` by the end of execution and wait until outer display list execution will do that.	2025-04-02 23:22:38 +02:00
Sam Atkins	3af25b9d2f	LibWeb/SVG: Mark SVG factory functions as [NewObject] ... Corresponds to 9991813a66	2025-04-02 17:28:45 +01:00
Sam Atkins	b74ec1ab7e	LibWeb/SVG: Remove fixme about SVGSVGElement::getElementById() ... Resolved in e02e2c6465	2025-04-02 17:28:45 +01:00
Sam Atkins	07adbddbcd	LibWeb/SVG: Remove SVGAElement.text attribute ... Corresponds to 7210af6604	2025-04-02 17:28:45 +01:00
Sam Atkins	02e8c0e1d1	LibWeb/HTML: Allow throwing SecurityError for push/replaceState() abuse ... Corresponds to 73e51b414b	2025-04-02 17:28:06 +01:00
Sam Atkins	7367150536	LibWeb/HTML: Update FIXME to not reset form-associated custom elements ... Corresponds to e6bdd0557a	2025-04-02 17:28:06 +01:00
Sam Atkins	86b57a5205	LibWeb/CSS: Use font_format_is_supported() when parsing font sources	2025-04-02 15:53:50 +01:00
Tim Ledbetter	cbb169820a	LibWeb/CSS: Implement the CSSImportRule.media attribute	2025-04-02 13:53:03 +01:00

Timothy Flynn	0de017df9b	LibRequests: Move NetworkError stringification to LibRequests ... Let's also rename the file to NetworkError.h while we're here. No need to have "Enum" in the name.	2025-04-02 08:52:45 -04:00
Shannon Booth	a5df972055	LibWeb: Do not store network errors as a StringView ... This is very clearly a very dangerous API to have, and was causing a crash on Linux as a result of a stack use-after-free when visiting https://www.index.hr/. Fixes #3901	2025-04-02 11:43:53 +02:00
Kenneth Myhra	82a2ae99c8	Everywhere: Remove DeprecatedFlyString + any remaining references to it ... This reverts commit 7c32d1e8a5.	2025-04-02 11:43:13 +02:00
Aliaksandr Kalenik	fd147e6be0	LibWeb: Protect SkiaBackendContext with a mutex ... The Skia Ganesh backend we currently use doesn't support painting from multiple threads, which could happen before this change when the main thread used Skia to paint on the HTML canvas while the rendering thread was working on display list rasterization. Fixes https://github.com/LadybirdBrowser/ladybird/issues/4172	2025-04-01 23:39:05 +02:00
Aliaksandr Kalenik	24527b6ae3	LibWeb: Pass PaintingSurface into DisplayListPlayer::execute() ... Deleteing set_surface() makes DisplayListPlayer API a bit more intuitive because now caller doesn't have to think whether it's necessary to restore previous surface after execution, instead DisplayListPlayer takes care of it by maintaining a stack of surfaces.	2025-04-01 23:39:05 +02:00
Jelle Raaijmakers	23f0fddeab	LibWeb: Let LineBuilder decide on Y-coordinate for float insertion ... Instead of reaching into the IFC of the LineBuilder from the BFC, we should let LineBuilder determine how to deal with the running vertical float clearance. No functional changes.	2025-04-01 16:02:53 +02:00
Jelle Raaijmakers	6d911a6baa	LibWeb: Resolve block height correctly after line break with clear: .. ... If a block with inline children ends with a line break clearing any floats, we not only need to take the introduced clearance into account for the next line box, but the containing block needs to set the correct height as well. Since the spec calls for using the last line box' bottom as the resolved height (if treated as auto), we now correctly apply the clearance to the previous line box' bottom coordinate. Fixes #4058.	2025-04-01 16:02:53 +02:00
Andreas Kling	7c32d1e8a5	Revert "Everywhere: Remove DeprecatedFlyString + any remaining references to it" ... This reverts commit 3131e6369f. Greatly regressed JavaScript benchmark performance.	2025-04-01 15:40:27 +02:00
Jelle Raaijmakers	45905d6f7b	LibWeb: Use relative coordinates for available_space_for_line() ... We were accidentally providing it with absolute Y-coordinates, messing up stacked floating boxes that would otherwise intrude on each other. Fixes #4160.	2025-04-01 15:26:12 +02:00
Jelle Raaijmakers	a728d67ac2	LibWeb: Only calculate float intrusions for definite available width ... No functional changes.	2025-04-01 15:26:12 +02:00
Glenn Skrzypczak	da09608156	LibWeb/Painting: Fix blending with viewport background ... The viewport is now drawn onto transparent black instead of the background color of the viewport.	2025-04-01 13:38:00 +02:00
Glenn Skrzypczak	9973b01848	LibWeb/CSS: Improved implementation of background-blend-mode ... This is a improved version of a73cd88f0c The old commit was reverted in 552dd18696 The new version only paints an element into a new layer if background blend modes other than normal are used. The rasterization performance of most websites should therefore not suffer. Co-Authored-By: Alexander Kalenik <kalenik.aliaksandr@gmail.com>	2025-04-01 13:38:00 +02:00
Glenn Skrzypczak	6906f1722a	LibWeb/Painting: Add back SaveLayer command ... This reverts commit 552dd18696.	2025-04-01 13:38:00 +02:00

Timothy Flynn	004173f88b	LibWeb: Allow parsing of "file" prompt types in WebDriver ... See: 3055808 This isn't actually used outside of BiDi.	2025-04-01 03:52:02 +02:00
Timothy Flynn	952ad4e68b	LibWeb: Allow fractional numbers for WebDriver mouse-move coordinates ... See: a67669c	2025-04-01 03:52:02 +02:00
Luke Wilde	ee6dbcc96e	LibWeb: Apply HTMLFontElement's face attribute's presentational hint ... Fixes font selection on https://stagsnet.net/	2025-04-01 03:50:30 +02:00
Aliaksandr Kalenik	e33174fca1	LibWeb: Make BackingStore atomic ref-counted ... This is required to make sure rendering thread will keep backing stores alive in case backing stores reallocation happens during rasterization. Fixes https://github.com/LadybirdBrowser/ladybird/issues/4164	2025-04-01 03:05:21 +02:00
Glenn Skrzypczak	1022566bff	LibWeb/Layout: Properly remove layout nodes ... This properly remove the old layout node subtree when no new layout node is created during layout update.	2025-03-31 18:19:58 +01:00
Aliaksandr Kalenik	24e2c402f5	LibWeb+WebContent: Move display list rasterization off the main thread ... The display list is an immutable data structure, so once it's created, rasterization can be moved to a separate thread. This allows more room for performing other tasks between processing HTML rendering tasks. This change makes PaintingSurface, ImmutableBitmap, and GlyphRun atomic ref-counted, as they are shared between the main and rendering threads by being included in the display list.	2025-03-31 15:58:15 +01:00
Jelle Raaijmakers	86b831750d	LibWeb: Layout children a bit earlier in BlockFormattingContext ... We don't need to duplicate this piece of code. No functional changes.	2025-03-31 08:11:10 +01:00
Jelle Raaijmakers	04ba375cc7	LibWeb: Only set line builder's block offset if clearance increases it ... This prevents text from overlapping with each other if a `<br>` with `clear: ..` is used in between.	2025-03-31 08:11:10 +01:00
Timothy Flynn	6f1710121d	LibWeb: Remove OOM handling from the AutoplayAllowlist	2025-03-30 16:18:57 +01:00
Timothy Flynn	c7979a8bd6	LibWeb: Add missing forward-include to AutoplayAllowlist ... This just lets clangd index this file.	2025-03-30 16:18:57 +01:00
Tim Ledbetter	568531f06a	Everywhere: Mark GC::Cell derived classes as Weakable explicitly ... Previously, all `GC::Cell` derived classes were Weakable. Marking only those classes that require this functionality as Weakable allows us to reduce the memory footprint of some frequently used classes.	2025-03-29 17:36:33 -05:00
Totto16	b66e7ac1ba	LibWeb: Implement BarProp properties for Window	2025-03-29 02:35:27 +00:00
Andreas Kling	ba8aabdeb0	Revert "LibWeb: Skip "overlay" paint phase when there's no inspected node" ... This reverts commit dc56435ecd. It broke overlay scrollbars.	2025-03-28 20:08:48 +00:00
Aliaksandr Kalenik	1229328adc	Revert "LibWeb/Painting: Add SaveLayer command" ... This reverts commit 1898643ba4.	2025-03-28 16:48:03 +00:00
Aliaksandr Kalenik	552dd18696	Revert "LibWeb/CSS: Implement 'background-blend-mode'" ... This reverts commit a73cd88f0c. Emitting SaveLayer for each paintable made rasterization a lot slower on every website because now Skia has to allocate enormous amounts of temporary surfaces. Let's revert it for now and figure how to implement it with less aggressive SaveLayer usage.	2025-03-28 16:48:03 +00:00
Andreas Kling	c71772126f	LibJS: Remove ByteString internals from PrimitiveString ... PrimitiveString is now internally either UTF-8, UTF-16, or both. We no longer convert them to/from ByteString anywhere, nor does VM have a ByteString cache.	2025-03-28 12:31:40 -04:00
