Shannon Booth	8a3c66d8a6	LibWeb: Make a bunch of CSP classes not realm associated ... These are not associated with a javascript realm, so to avoid confusion about which realm these need to be created in, make all of these objects a GC::Cell, and deal with the fallout.	2025-04-28 12:41:28 +02:00
Tim Ledbetter	04fde1c550	LibWeb: Ensure lang pseudoclass matches multiple segment subcodes	2025-04-28 11:29:30 +01:00
Tim Ledbetter	74c803c87b	LibWeb: Ensure |= value selector handles multiple segments correctly ... Previously, the `|=` would not compare strings containing `-` characters correctly because it would only compare the element attribute up to the first `-` character.	2025-04-28 11:29:30 +01:00
devgianlu	1c3d849b8b	LibCrypto: Remove unused big numbers modular functions ... Remove `Mod`, `ModularInverse`, `ModularPower` and `LCM` as they are unused.	2025-04-28 12:05:26 +02:00
devgianlu	5f1a30197c	LibCrypto: Remove the concept of invalid big integers ... This concept is rarely used in codebase and very much error-prone if you forget to check it. Instead, make it so that operations that would produce invalid integers return an error instead.	2025-04-28 12:05:26 +02:00
devgianlu	14387e5411	LibCrypto: Remove unused big numbers random and primality functions ... Remove `random_number`, `is_probably_prime` and `random_big_prime` as they are unused.	2025-04-28 12:05:26 +02:00
devgianlu	dd0cced92f	LibJS: Prevent huge memory allocations for bigint left shift	2025-04-28 12:05:26 +02:00

devgianlu	ce98d2bbf3	LibCrypto: Check ECPrivateKey version when parsing ... The version should always be one for version one. Fail if it isn't.	2025-04-28 12:05:26 +02:00
devgianlu	a019efb24b	LibCrypto+LibJS: Remove {Signed,Unsigned}BigInteger to_base_deprecated ... Use `to_base` instead.	2025-04-28 12:05:26 +02:00

stelar7	facfcd87c2	LibWeb/IDB: Introduce an Invalid KeyType ... This cleans up the code around failure/invalid/exception a bit	2025-04-28 11:31:31 +02:00
stelar7	61384473ca	LibWeb/IDB: Implement IDBDatabase::transaction()	2025-04-28 11:31:31 +02:00
Andreas Kling	a05be67e4a	LibJS: Let invokers (callers) of [[Call]] allocate ExecutionContext ... Instead of letting every [[Call]] implementation allocate an ExecutionContext, we now make that a responsibility of the caller. The main point of this exercise is to allow the Call instruction to write function arguments directly into the callee ExecutionContext instead of copying them later. This makes function calls significantly faster: - 10-20% faster on micro-benchmarks (depending on argument count) - 4% speedup on Kraken - 2% speedup on Octane - 5% speedup on JetStream	2025-04-28 01:23:56 +02:00
Andreas Kling	93788f8057	LibJS: Add parentheses to ALLOCATE_EXECUTION_CONTEXT_ON_NATIVE_STACK() ... Just to stop clang-tidy from complaining about it every time.	2025-04-28 01:23:56 +02:00
Andreas Kling	373307db5b	LibJS: Mark arguments local as initialized after creating it ... This avoids emitting an unnecessary TDZ check for the first time we access the arguments object.	2025-04-28 01:23:56 +02:00
Shannon Booth	9e44d86915	LibJS: Remove value_or from JS::Value ... This is no longer used after 3cf5053.	2025-04-27 11:14:54 -04:00
Shannon Booth	420949b134	LibWeb/HTML: Make Navigation navigate event trusted ... Fixes WPT test: https://wpt.live/navigation-api/navigate-event/signal-abort-intercept.html	2025-04-27 07:54:02 -04:00
Shannon Booth	6032827fe7	LibWeb/HTML: Inform navigation API about frame container destruction	2025-04-27 07:54:02 -04:00
Ali Mohammad Pur	022cd1adca	LibRegex: Use the right offset when patching jumps through fork-trees ... Fixes #4474.	2025-04-27 12:16:15 +02:00
Tim Ledbetter	8a398e7a88	LibWeb: Parse all transition-property value as keyword ... We were previously parsing this value, as a custom-ident, meaning that the code path for handling the `all` case wasn't being followed.	2025-04-27 09:49:00 +01:00
Timothy Flynn	ac1c2a956a	LibWeb: Implement caching of reflected element array attributes ... For attributes like Element.ariaControlsElements, which are a reflection of FrozenArray<Element>, we must return the same JS::Array object every time the attribute is invoked - until its contents have changed. This patch implements caching of the reflected array in accordance with the spec.	2025-04-26 17:29:38 -04:00
Timothy Flynn	6f894ccd77	Meta: Remove -Wno-overloaded-virtual from clang compilation ... This silenced warning was added a long time ago when we were first bringing up Lagom: a619943001 The commit message indicates we were seeing errors due to this warning in many places. We now compile just fine with this warning enabled, so let's remove its silencer to be a little more consistent between clang and GCC.	2025-04-26 09:04:45 -06:00
Timothy Flynn	317cf65eb0	LibJS: Avoid naming conflict between Object's and Error's is_error ... Object defines an is_error virtual method to be overridden by Error for fast-is. This is the same name as the Error.isError constructor method. Rename the former to avoid conflicts, as GCC 15 just started warning on this.	2025-04-26 09:04:45 -06:00
Shannon Booth	6d622a6c04	LibWeb/DOM: Use as_if<T> in a bunch more places in DOM::Node	2025-04-26 08:45:37 -06:00
Shannon Booth	31a3bc3681	LibWeb: Implement 'State-preserving atomic move integration' ... This was recently added to both the HTML and DOM specifications, introducing the new moveBefore DOM API, as well as the new internal 'removing steps'. See: * 432e8fb * eaf2ac7	2025-04-26 08:45:37 -06:00
Shannon Booth	a47c4dbc63	LibWeb/DOM: Factor out 'live range pre remove steps' AO ... This was a refactoring made in the DOM spec as part of the introduction of the move before API.	2025-04-26 08:45:37 -06:00
Timothy Flynn	0e2036d6c2	LibWeb: Temporarily disable site isolation for subframes ... We don't yet support out-of-process subframes. Explicitly disable even attempting to isolate subframes. Otherwise, navigating a subframe to a non-same-site URL would actually cause the top-level frame to navigate with our current implementation.	2025-04-26 10:15:47 -04:00
Timothy Flynn	e52c09ad4c	LibWeb: Avoid copying a URL needlessly during subframe navigation ... Noticed a clangd warning for this while looking at a subframe site isolation issue.	2025-04-26 10:15:47 -04:00
Aliaksandr Kalenik	2d732b2251	LibJS: Skip allocating locals for arguments that allowed to be local ... This allows us to get rid of instructions that move arguments to locals and allocate smaller JS::Value vector in ExecutionContext by reusing slots that were already allocated for arguments. With this change for following function: ```js function f(x, y) { return x + y; } ``` we now produce following bytecode: ``` [ 0] 0: Add dst:reg6, lhs:arg0, rhs:arg1 [ 10] Return value:reg6 ``` instead of: ``` [ 0] 0: GetArgument 0, dst:x~1 [ 10] GetArgument 1, dst:y~0 [ 20] Add dst:reg6, lhs:x~1, rhs:y~0 [ 30] Return value:reg6 ```	2025-04-26 11:02:29 +02:00
Aliaksandr Kalenik	3f04d18ef7	LibJS: Add new operand type for function arguments ... This allows us to directly access passed arguments instead of copying them to register/local first using GetArgument instruction.	2025-04-26 11:02:29 +02:00
Aliaksandr Kalenik	81a3bfd492	LibJS: Allow using locals if arguments is used in strict mode ... Previously we blocked using locals for function arguments whenever `arguments` was mentioned in function body, however, this is not necessary in strict mode, where mutations to the arguments object are not reflected in the function arguments and vice versa.	2025-04-25 21:08:24 +02:00
Andreas Kling	d8ea16d94e	LibWeb: Don't assume calc() simplification worked on invalid tree ... Fixes #4469	2025-04-25 16:55:05 +02:00
Timothy Flynn	4e298db4f5	LibWeb: Update FIXMEs about FrozenArray with more up-to-date description ... We could support FrozenArray pretty easily here, but we would regress on SameObject handling.	2025-04-25 16:43:43 +02:00
Timothy Flynn	ad34fdad48	LibWeb: Convert trivial attributes to FrozenArray	2025-04-25 16:43:43 +02:00
Timothy Flynn	62167d923c	LibWeb: Convert ARIA attributes to FrozenArray	2025-04-25 16:43:43 +02:00
Timothy Flynn	98f73a6b31	LibWeb: Implement FrozenArray IDL attributes ... A FrozenArray is simply a sequence whose integrity level is "frozen".	2025-04-25 16:43:43 +02:00
Andreas Kling	cf704cfbfc	LibWeb: Implement interpolation for CSS scale values ... And let's handle the 3rd (Z) scale parameter as well, while we're here. At least 242 new passes on WPT.	2025-04-25 14:08:12 +02:00
Andreas Kling	4f4b43f1d2	Tests: Import WPT test for CSS scale interpolation	2025-04-25 14:08:12 +02:00
Shannon Booth	a2cca59516	LibWeb+LibWebView+Services: Add IPC for starting WebWorker of a type ... The provides some of the plumbing for a WebContent process to spin up a WebWorker that is not just a dedicated worker.	2025-04-25 14:07:51 +02:00
Shannon Booth	041ff0c7ff	LibWeb/HTML: Hook up a WorkerAgent for web workers	2025-04-25 14:07:51 +02:00
Shannon Booth	5290ebfe19	LibJS: Switch Agent [[CanBlock]] slot to a enum member ... It turns out it was a mistake to make this a virtual since ServiceWorkerAgents are effectively the exact same as DedicatedWorkerAgents and SharedWorkerAgents just with [[CanBlock]] set to false.	2025-04-25 14:07:51 +02:00
Shannon Booth	7dd7e5b438	LibJS+LibWeb: Defer initialization of the Agent after VM constructor ... This helps unwind a niggly depedency where the VM owns and constructs the Heap and the Agent. But the agent wants to have customized construction that depends on the heap. Solve this by defering the initialization of the Agent to after we have constructed the VM and the heap.	2025-04-25 14:07:51 +02:00
Shannon Booth	8263a9863f	LibJS+LibWeb: Do not return error from VM::create ... This never returns an error to propogate, also allowing ErrorOr to be removed from creating the main thread VM.	2025-04-25 14:07:51 +02:00
Shannon Booth	084cceab5c	LibWeb: Split out SimilarOriginWindowAgent from HTML::Agent ... To allow for adding the concept of a WorkerAgent to be reused between shared and dedicated workers. An event loop is the commonality between the different agent types, though, there are some differences between those event loops which we customize on the construction of the HTML::EventLoop.	2025-04-25 14:07:51 +02:00
Shannon Booth	939bb10828	LibWeb/HTML: Rename WorkerAgent to WorkerAgentParent ... This is to differentiate the agent representation for the parent process for the WorkerAgent in the child process which is actually hooked up to the javascript VM. I am not sure if this is a good name, but I can't really think of anything better which is consistent with the names used by the rest of the codebase.	2025-04-25 14:07:51 +02:00
