This reduces the size of WebIDL::ExceptionOr<T> as follows for a few
different Ts:
WebIDL::ExceptionOr<void>: 48 bytes to 40 bytes
WebIDL::ExceptionOr<JS::Value>: 48 bytes to 40 bytes
WebIDL::ExceptionOr<String>: 56 bytes to 40 bytes
Comes with the usual benefit of saving some space on the stack, as well
as making a situation where both or neither Optionals hold a value
impossible.
The various unwrapping additions are required as we can no longer
construct a ThrowCompletionOr<T> from an Optional<T> - rightfully so.
This would never return an empty optional or non-numeric value, and in
fact every caller as_double()'d the value right away.
Let's make the type match reality instead :^)
Similar to the FontDatabase, this will be needed for Ladybird to find
emoji images. We now generate just the file name of emoji image in
LibUnicode, and look for that file in the specified path (defaulting to
/res/emoji) at runtime.
Currently, if you use the left/right arrow keys to move over a multi-
code point glyph, we will move through that glyph one code point at a
time. This means you can "pause" your movement in the middle of a glyph
and delete a subsection of a grapheme cluster. This now moves the cursor
across the entire cluster.
u64 is not big enough to hold extremely large numbers, such as
4.192938423e+54. This would cause an integer underflow on the radix
index when performing something like `toString(36)` and thus cause an
OOB Array read.
This prevents us setting up the document of a removed browsing context
container (BCC, e.g. <iframe>), which will cause a crash if the
document contains a script that inserts another BCC as this will use
the stale browsing context it previously set up, even if it's
reinserted.
Required by Prebid.js, which does this by inserting an `<iframe>` into
a `<div>` in the active document via innerHTML, then transfers it to
the `<html>` element:
7b7389c5ab/src/utils.js (L597)
This is done in the spec by removing all tasks and aborting all fetches
when a document is destroyed:
https://html.spec.whatwg.org/multipage/document-lifecycle.html#destroy-a-document
See the code comments for a simplified example.
This is not guaranteed to always work correctly as ArgsParser deals in
StringViews and might have a non-properly-null-terminated string as a
value. As a bonus, using StringView (and DeprecatedString where
necessary) leads to nicer looking code too :^)
This feature allows any application to easily install an automatically
updating list of recently open files in a GUI::Menu.
There are three main pieces to this mechanism:
- GUI::Application::set_config_domain(domain): This must be called
before using the recent files feature. It informs the Application
object about which config domain to find the relevant RecentFiles
list under.
- GUI::Menu::add_recently_open_files(callback): This inserts the list
in a menu. A callback must be provided to handle actually opening
the recent file in some application-specific way.
- GUI::Application::set_most_recently_open_file(path): This updates
the list of recently open files, both in the configuration files,
and in the GUI menu.
This adds an option to only detect emoji that should always present as
emoji. For example, the copyright symbol (unless followed by an emoji
presentation selector) should render as text.
`consume_until(foo)` stops before foo, and so does
`ignore_until(Predicate)`, so let's make the other `ignore_until()`
overloads consistent with that so they're less confusing.
Each {} block is now treated as a folding region, so that they can be
collapsed and expanded in TextEditor, HackStudio, and anywhere else
that uses the syntax highlighter. :^)

Previously this stored the position of each visual line break, meaning
that all the text would always be painted. By storing each visual
line's Utf32View, we can skip over parts of the text, such as for code
folding.
This only becomes a problem with folding, since arbitrary lines may be
invisible, meaning we try to apply a span for an invisible line N, on
line N+X instead, causing occasional crashes.
This check means we can remove the loop that skips spans occurring at
the end of the line.
This commit moves the implementation of getopt into AK, and converts its
API to understand and use StringView instead of char*.
Everything else is caught in the crossfire of making
Option::accept_value() take a StringView instead of a char const*.
With this, we must now pass a Span<StringView> to ArgsParser::parse(),
applications using LibMain are unaffected, but anything not using that
or taking its own argc/argv has to construct a Vector<StringView> for
this method.
This currently allocates in .parse(), but that's better than making the
caller do the exact same before passing us the values.
Note that this is only temporary to aid in conversion, a future commit
will remove this and switch to requiring the users to allocate the
vector instead.
With the GC heap conversion, the functionality of legacy platform
objects was broken. This is because the generated implementation of one
of them was used for all of them, removing functionality such as
deletion.
This re-adds all functionality, where questions such as "does the
object support indexed properties?" is instead answered by virtual
functions instead of by the IDL generator checking the presence of
certain keywords/attributes.
The name "initial containing block" was wrong for this, as it doesn't
correspond to the HTML element, and that's specifically what it's
supposed to do! :^)
Using char causes bytes equal to or over 0x80 to be treated as a
negative value and produce incorrect results when implicitly casting to
u32.
For example, `atob` in LibWeb uses this decoder to convert non-ASCII
values to UTF-8, but non-ASCII values are >= 0x80 and thus produces
incorrect results in such cases:
```js
Uint8Array.from(atob("u660"), c => c.charCodeAt(0));
```
This used to produce [253, 253, 253] instead of [187, 174, 180].
Required by Cloudflare's IUAM challenges.
Defining it as a direct property causes it to have no getter/setter
function, which causes an empty Optional crash when attempting to
access such getter on a cross-origin iframe.
Fixes amazon.com crashing on this particular crash.
