Luke Wilde	278666edcd	LibWeb: Enforce Content Security Policy on navigation request/response	2025-04-01 04:01:28 +02:00
Timothy Flynn	004173f88b	LibWeb: Allow parsing of "file" prompt types in WebDriver ... See: https://github.com/w3c/webdriver/commit/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: https://github.com/w3c/webdriver/commit/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
Andreas Kling	a0bb31f7a0	LibJS: Make async functions & generators faster with helper types ... Instead of returning internal generator results as ordinary JS::Objects with properties, we now use GeneratorResult and CompletionCell which both inherit from Cell directly and allow efficient access to state. 1.59x speedup on JetStream3/lazy-collections.js :^)	2025-04-01 02:30:42 +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	ed265b568d	LibWebView+WebContent+UI: Migrate to the new autoplay settings ... This removes the old autoplay allowlist file in favor of the new site setting. We still support the command-line flag to enable autoplay globally, as this is needed for WPT.	2025-03-30 16:18:57 +01:00
Timothy Flynn	223b04f087	LibWebView: Add autoplay settings to about:settings ... The idea with the UI here is that it will serve as a generic component for all site settings, such as autoplay, notifications, etc. When the site settings dialog is opened, it is filled with the requested setting data, and messages sent to the browser process are based on the setting. This patch only implements the UI and persisted settings. It does not apply autoplay changes to the WebContent process.	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
Andreas Kling	4dc63ddf49	LibJS: Make Optional<Utf16String> use less space ... By specializing the template, we can shrink it from 16 to 8 bytes. This makes PrimitiveString a measly 32 bytes. :^)	2025-03-30 07:16:40 +01:00
Andreas Kling	152691f9eb	LibWeb: Make RopeString subclass so PrimitiveString can be smaller ... By moving the LHS and RHS pointers used by rope strings into a RopeString subclass, we shrink PrimitiveString by 16 bytes. Most strings are not rope strings, so this ends up saving quite a bit of memory.	2025-03-30 07:16:40 +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	2462a6b0fa	LibJS: Use Value::to_byte_string() in fewer places	2025-03-28 12:31:40 -04:00
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
Timothy Flynn	f05b0bfd5f	LibWeb+LibWebView+WebContent: Convert about:settings to a WebUI	2025-03-28 07:31:10 -04:00
Timothy Flynn	c75e40180c	LibWeb+LibWebView+WebContent: Convert about:processes to a WebUI	2025-03-28 07:31:10 -04:00
Timothy Flynn	41aeb9e63a	LibWeb+LibWebView+WebContent: Introduce a WebUI framework ... When we build internal pages (e.g. about:settings), there is currently quite a lot of boilerplate needed to communicate between the browser and the page. This includes creating IDL for the page and the IPC for every message sent between the processes. These internal pages are also special in that they have privileged access to and control over the browser process. The framework introduced here serves to ease the setup of new internal pages and to reduce the access that WebContent processes have to the browser process. WebUI pages can send requests to the browser process via a `ladybird.sendMessage` API. Responses from the browser are passed through a WebUIMessage event. So, for example, an internal page may: ladybird.sendMessage("getDataFor", { id: 123 }); document.addEventListener("WebUIMessage", event => { if (event.name === "gotData") { console.assert(event.data.id === 123); } }); To handle these messages, we set up a new IPC connection between the browser and WebContent processes. This connection is torn down when the user navigates away from the internal page.	2025-03-28 07:31:10 -04:00
Lucien Fiorini	f72d87931f	LibJS: Reduce Mov instructions by using preferred destinations	2025-03-28 11:21:12 +00:00
Lucien Fiorini	5707076b9e	LibJS: Optimize away Mov instructions when the source is the destination	2025-03-28 11:21:12 +00:00
Sam Atkins	192cae17ee	LibWeb/DOM: Update step 4 of load_document() ... Corresponds to 2ab779b8e8 We don't implement most of what that touches, so the only actual change is a couple of words added here.	2025-03-28 11:18:57 +00:00
Glenn Skrzypczak	a73cd88f0c	LibWeb/CSS: Implement 'background-blend-mode' ... This implements the 'background-blend-mode' CSS property.	2025-03-28 09:41:06 +00:00
Glenn Skrzypczak	1898643ba4	LibWeb/Painting: Add SaveLayer command ... This adds a command for saving the current layer of the canvas. This is useful for painting content onto a blank background in isolation and later compositing it onto the canvas.	2025-03-28 09:41:06 +00:00
Sam Atkins	09b8f73e11	LibWeb/CSS: Implement UnicodeRangeStyleValue ... This is preparation for storing at-rule descriptors as style values.	2025-03-28 09:15:02 +00:00
Sam Atkins	e0a03147c6	LibGfx: Make UnicodeRange comparable	2025-03-28 09:15:02 +00:00
Sam Atkins	ef3a2bf907	LibWeb/CSS: Move functions for detecting var()/attr() into Token types ... This makes them accessible outside of PropertyParsing.cpp (which will be useful if/when descriptors can include them). I've also renamed them to use the correct term: "arbitrary substitution function".	2025-03-28 09:15:02 +00:00
Aliaksandr Kalenik	732a5cdc12	LibWeb: Respect min/max-content available size in auto width calculation ... ...for block level boxes. Otherwise we end up resolving auto width as zero during intrinsic layout, which leads to incorrectly applied max-width constraint. Fixes https://github.com/LadybirdBrowser/ladybird/issues/4123	2025-03-28 02:13:41 +00:00
Luke Wilde	c7d25301d3	LibWeb: Implement the LegacyUnforgeable attribute ... This fixes the frame-ancestors WPT tests from crashing when an iframe is blocked from loading. This is because it would get an undefined location.href from the cross-origin iframe, which causes a crash as it expects it to be there.	2025-03-27 23:50:35 +00:00
Tim Ledbetter	7853b757c2	LibWeb: Lower the baseline of text with veritcal-align: sub ... This lowers the baseline of the given text by one fifth of the parent's font size.	2025-03-27 23:30:57 +00:00
Tim Ledbetter	6fbbbc9b81	LibWeb: Raise the baseline of text with veritcal-align: super ... This raises the baseline of the given text by one third of the parent's font size.	2025-03-27 23:30:57 +00:00
Aliaksandr Kalenik	fc45121b70	LibWeb: Size box as normal if it has aspect ratio but auto sizes ... Otherwise we apply `calculate_stretch_fit_width()` instead of calculating width based on the content inside the box, like other browsers do.	2025-03-27 23:13:57 +00:00
Jelle Raaijmakers	006f276cab	LibWeb: Copy IDBDatabase object stores through Vector(ReadonlySpan) ... Prevents a crash because `ReadonlySpan.copy_to()` was trying to copy to an empty vector. Fixes #4127.	2025-03-27 23:13:32 +00:00
Andreas Kling	f5dd776b11	LibJS: Remove some irrelevant hash lookups in ESFO constructor ... If we don't have parameter expressions, we don't need to collect metadata about whether instantiated var names collide with parameter names or function names, as these flags are only used in the parameter code path.	2025-03-27 23:12:04 +00:00
Andreas Kling	c037bda455	LibJS: Use a premade shape for normal function objects ... This avoids going through all the shape transitions when setting up the most common form of ESFO. This is extremely hot on Uber Eats, and this provides some relief.	2025-03-27 23:12:04 +00:00
Oliver Medhurst	60fd406903	LibWeb: Fix inside list style overriding content offset ... Previously, if a horizontal margin was set on a list-item and it was list-style-position: inside, it would effectively remove that margin.	2025-03-27 23:10:09 +00:00
Oliver Medhurst	b272bb3373	LibWeb: Fix ::marker placement in tree ... Fixes ::marker (pseudo-element) placement in the tree for list-items. Previously: - ::before - content - ::marker - ::after Now (matches Firefox, afaik per-spec): - ::marker - ::before - content - ::after	2025-03-27 23:10:09 +00:00
Manuel Zahariev	9e7436a096	LibWebView: Better integration of sanitize_url with search ... With search enabled: - For a single word that does not look like a url: search (a reported bug). - If no suffix or a suffix that is not recognized: search. In general: - Respect the user's choice if they specified a scheme. - Respect localhost and registered TLDs. - As before, add file:// to filesystem files that exist.	2025-03-27 18:30:08 -04:00
Andreas Kling	5ea45da15f	LibJS: Store NewObject result directly in preferred dst if possible ... This avoids a Mov after every object literal.	2025-03-27 19:50:13 +00:00
Andreas Kling	900f209b34	LibJS: Make Optional<Operand> use less space ... Shrink these down from 12 bytes to 8 bytes, which helps make many bytecode instructions smaller.	2025-03-27 19:50:13 +00:00
Andreas Kling	a29d820f87	LibJS: Make Optional<IdentifierTableIndex> use less space ... We can use the index's invalid state to signal an empty optional. This makes Optional<IdentifierTableIndex> 4 bytes instead of 8, shrinking every bytecode instruction that uses these.	2025-03-27 19:50:13 +00:00
Andreas Kling	904beef6d2	LibJS: Put newly instantiated functions into locals more efficiently ... - Don't allocate a separate register, store directly into the local. - Mark the local as initialized to avoid emitting TDZ checks.	2025-03-27 19:50:13 +00:00
Andreas Kling	6c70dc5f09	LibJS: Create FunctionParameters earlier in the parser ... This avoids making multiple copies of the Vector<FunctionParameter> in the parser.	2025-03-27 19:50:13 +00:00
