Luke Wilde	b17783bb10	Everywhere: Change west consts caught by clang-format-21 to east consts	2025-08-29 18:18:55 +01:00
Luke Wilde	847589404b	LibWeb: Set filename of module scripts to full URL instead of basename ... Atlassian login gets the base URL for its module scripts by throwing an error and pulling out the current script's URL from error.stack with regex. Since we only returned a basename for module scripts, it would fail to match and try and use `/` as a base URL (because it does [matched_string] + "/"), which is not a valid base URL.	2025-08-26 15:46:45 +02:00
ayeteadoe	3df8e00d91	LibWeb: Enable EXPLICIT_SYMBOL_EXPORT	2025-08-23 16:04:36 -06:00
Timothy Flynn	70db474cf0	LibJS+LibWeb: Port interned bytecode strings to UTF-16 ... This was almost a no-op, except we intern JS exception messages. So the bulk of this patch is porting exception messages to UTF-16.	2025-08-14 10:27:08 +02:00
Timothy Flynn	b955c9b2a9	LibJS: Port the Identifier AST (and related) nodes to UTF-16 ... This eliminates quite a lot of UTF-8 / UTF-16 churn.	2025-08-13 09:56:13 -04:00
Sam Atkins	4bcfc4bacc	LibWeb/HTML: Add cross-site ancestor flag to environment ... Corresponds to baec061a70	2025-08-11 11:08:04 +01:00
Luke Wilde	40bb50ac60	LibWeb: Parse and propagate the iframe sandbox attribute	2025-08-07 19:24:39 +02:00
Timothy Flynn	1bc80848fb	AK+LibWeb: Add a UTF-16 starts/ends with wrapper for a single code unit	2025-08-07 02:05:50 +02:00
Timothy Flynn	0efa98a57a	LibJS+LibWeb+WebContent: Port JS::PropertyKey to UTF-16 ... This has quite a lot of fall out. But the majority of it is just type or UDL substitution, where the changes just fall through to other function calls. By changing property key storage to UTF-16, the main affected areas are: * NativeFunction names must now be UTF-16 * Bytecode identifiers must now be UTF-16 * Module/binding names must now be UTF-16	2025-08-05 07:07:15 -04:00
Andreas Kling	66a19b8550	LibWeb: Make ESO "fetch group" weakly reference the fetch records ... Otherwise we end up holding on to every fetch record indefinitely. Found by analyzing GC heap graphs on Discord.	2025-07-29 20:00:17 -04:00
Sam Atkins	91e8a19391	LibWeb: Always set [[ErrorToRethrow]] for import validation errors ... Corresponds to f6fb04a11f	2025-07-08 17:08:39 +01:00
Sam Atkins	da8a29376f	LibWeb: Use ThrowCompletion AO to create throw completions ... Corresponds to 4989b3457f	2025-07-08 17:08:39 +01:00
Shannon Booth	00002c6443	LibWeb/HTML: Unregister ESO during finalize phase ... It is generally safer for GC cells to do cleanup work during the finalize phase.	2025-06-18 13:08:30 +02:00
Shannon Booth	e0d7278820	LibURL+LibWeb: Make URL::Origin default constructor private ... Instead, porting over all users to use the newly created Origin::create_opaque factory function. This also requires porting over some users of Origin to avoid default construction.	2025-06-17 20:54:03 +02:00
Shannon Booth	1a34485460	LibWeb/HTML: Serialize time origin in environments ... Which is caught from changing across to this form of initializing the object.	2025-06-17 20:54:03 +02:00
Shannon Booth	bc4317be20	LibWeb/HTML: Handle failure determining mime type fetching module script ... Fixes crash in WPT test: https://wpt.live/html/semantics/scripting-1/the-script-element/css-module/content-type-checking.html	2025-05-31 09:15:52 -04:00
Shannon Booth	937994cfaa	LibWeb: Make Environment's top level origin nullable ... This matches the definition in the spec, and is also a step towards removing the default constructor of URL::Origin.	2025-05-27 14:48:43 +12:00
Shannon Booth	8ccb89877a	LibWeb/HTML: Return an opaque origin for data URLs for Workers	2025-05-24 09:51:44 -04:00
Andrew Kaster	4af0daf3eb	LibWeb: Check actual WorkerGlobalScope subclass to set top level origin ... Checking against DedicatedWorkerHost was probably a typo.	2025-05-18 17:50:05 -06:00
Timothy Flynn	7280ed6312	Meta: Enforce newlines around namespaces ... This has come up several times during code review, so let's just enforce it using a new clang-format 20 option.	2025-05-14 02:01:59 -06:00
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
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	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
Aliaksandr Kalenik	a329868c1b	LibJS: Allocate ExecutionContext memory using alloca() when possible ... This should be faster than heap allocation. However, heap allocation is still necessary in some cases, such as with generators and async functions.	2025-04-24 10:30:52 +02:00
Aliaksandr Kalenik	c6cd03d7ca	LibJS+LibWeb: Join arguments into vector of registers+constants+locals ... This is better because: - Better data locality - Allocate vector for registers+constants+locals+arguments in one go instead of allocating two vectors separately	2025-04-24 10:30:52 +02:00
Aliaksandr Kalenik	80a8040794	LibJS+LibWeb: Calculate count of regs+consts+locals before EC allocation ... This is a preparation step before joining arguments vector into vector of registers+constants+locals.	2025-04-24 10:30:52 +02:00
Shannon Booth	e124ef52ee	LibJS+LibWeb: Set [[CanBlock]] false to Agent for window agent ... similar-origin window agents have the [[CanBlock]] flag set to false. Achieve this by hooking up JS's concept with an agent to HTML::Agent. For now, this is only hooked up to the similar-origin window agent case but should be extended to the other agent types in the future.	2025-04-22 11:50:35 -04:00
Shannon Booth	96f38dc180	LibWeb/HTML: Make environments top level creation URL nullable ... This is explicitly set to null for Workers.	2025-04-22 08:44:50 -06:00
Andreas Kling	ce263eaf78	LibWeb: Avoid dynamic_cast in relevant_agent() ... There's only ever one kind of JS::VM::CustomData in play anyway.	2025-04-18 14:45:56 +02:00
Andreas Kling	a9e415b3c4	LibJS+LibWeb: Add fast_is<T> helpers for HTML::Script class family	2025-04-18 14:45:56 +02:00
Timothy Flynn	e9a7694cdb	LibWeb: Prefer react_to_promise over upon_fulfillment + upon_rejection ... While debugging a spec-compliant implementation of ReadableStreamPipeTo, I spent a lot of time inspecting promise internals. This is much less noisy if we halve the number of temporary promises.	2025-04-11 12:10:46 -04:00
Sam Atkins	9dbeecb73d	LibWeb: Correct some spec typos ... Corresponds to 285a58bf30	2025-04-10 04:01:37 +02:00
Andreas Kling	3cf50539ec	LibJS: Make Value() default-construct the undefined value ... The special empty value (that we use for array holes, Optional<Value> when empty and a few other other placeholder/sentinel tasks) still exists, but you now create one via JS::js_special_empty_value() and check for it with Value::is_special_empty_value(). The main idea here is to make it very unlikely to accidentally create an unexpected special empty value.	2025-04-05 11:20:26 +02:00
Andreas Kling	de424d6879	LibJS: Make Completion.[[Value]] non-optional ... Instead, just use js_undefined() whenever the [[Value]] field is unused. This avoids a whole bunch of presence checks.	2025-04-05 11:20:26 +02:00
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
Andreas Kling	46a5710238	LibJS: Use FlyString in PropertyKey instead of DeprecatedFlyString ... This required dealing with *substantial* fallout.	2025-03-24 22:27:17 +00:00
Andreas Kling	53da8893ac	LibJS: Replace PropertyKey(char[]) with PropertyKey(FlyString) ... ...and deal with the fallout.	2025-03-24 22:27:17 +00:00
Timothy Flynn	843209c6a9	LibWeb+LibWebView+WebContent: Add an about:processes page ... The intent is that this will replace the separate Task Manager window. This will allow us to more easily add features such as actual process management, better rendering of the process table, etc. Included in this page is the ability to sort table rows. This also lays the ground work for more internal `about` pages, such as about:config.	2025-03-19 10:03:17 -04:00
Sam Atkins	0efd1729af	LibWeb/HTML: Update navigation request's reserved client ... Fill in a couple of FIXMEs to discard an old reserved client, and/or create a new one, in `create_navigation_params_by_fetching()`.	2025-03-14 18:05:42 +01:00
Sam Atkins	5a4f15d8f5	LibWeb/HTML: Add environment discarding steps ... Exactly one place seems to define these at the moment: service worker clients. Since we don't have a type for these and just use EnvironmentSettingsObject, I've put it there.	2025-03-14 18:05:42 +01:00
Shannon Booth	b543523717	LibWeb: Fire slotchange events when a slot is changed	2025-03-10 14:37:26 -04:00
Feng Yu	ad9f70dff9	LibWeb: Clean up unused module script fetching algorithms ... This patch removes those unused 2 algorithms: 1. `fetch_internal_module_script_graph` 2. `fetch_descendants_of_a_module_script` Those 2 algorithms were removed in spec and are not used in our codebase.	2025-03-07 02:25:31 +01:00
Gingeh	93e2babc64	LibWeb: Prevent crash when loading module in worker ... The import map is defined for all global objects, not just the window.	2025-02-28 14:51:20 +01:00
Luke Wilde	cae0ab2139	LibWeb: Make PolicyContainer GC allocated ... This is required to store Content Security Policies, as their Directives are implemented as subclasses with overridden virtual functions. Thus, they cannot be stored as generic Directive classes, as it'll lose the ability to call overridden functions when they are copied.	2025-02-21 12:43:48 +00:00
Shannon Booth	705001483a	LibWeb: Make base URL of HTML::Script Optional ... This is a null or a URL in the spec, which we were previously representing through the invalid state of URL.	2025-02-19 08:01:35 -05:00
Shannon Booth	d62cf0a807	Everywhere: Remove some use of the URL constructors ... These make it too easy to construct an invalid URL, which makes it difficult to remove the valid state of URL - which this API relies on.	2025-02-19 08:01:35 -05:00
Shannon Booth	0b8bcdcbd3	LibWeb: Remove some useless URL validity checks ... It is not possible for a URL here to have a value and be invalid.	2025-02-19 08:01:35 -05:00
Shannon Booth	2c8dab36f3	LibWeb: Port EnvironmentSettings URL Parsing to return Optional<URL>	2025-02-19 08:01:35 -05:00
