We achieve this by keeping track of all checked pseudo class selectors
in the SelectorEngine code. We also give StyleComputer per-pseudo-class
rule caches.
This adds support for async iterators of the form:
async iterable<value_type>;
async iterable<value_type>(/* arguments... */);
It does not yet support the value pairs of the form:
async iterable<key_type, value_type>;
async iterable<key_type, value_type>(/* arguments... */);
Async iterators have an optional `return` data property. There's not a
particularly good way to know what interfaces implement this property.
So this adds a new extended attribute, DefinesAsyncIteratorReturn, which
interfaces can use to declare their support.
This near enough matches what CI does to build fuzzers, with the
differences being the explicit -GNinja and setting CMAKE_OSX_SYSROOT,
as CMake 4 no longer does that for us.
Reimplements c3121c9d at the transport layer, allowing us to solve the
same problem once, in a single place, for both the LibIPC connection and
MessagePort. This avoids exposing a workaround for a macOS specific Unix
domain socket issue to higher abstraction layers.
These generate what seems to be nonsense warnings on Function and
ByteBuffer; they *should* be investigated at some point, but they don't
provide anything useful at this point.
There's a bit of a UTF-8 assumption with this change. But nearly every
caller of these methods were immediately creating a String from the
resulting ByteString anyways.
Our handling of 'optional' return values was previously not correct
in that we would always call 'create_data_property' for every
single member of the returned dictionary, even if that property did
not have a value (by falling back to JS::js_null).
This was resulting in a massive number of test failures for URL
pattern which was expecting 'undefined' as the member value, instead
of 'null'.
This is a homegrown implementation that wasn't actually used in
dependent classes. If this is needed in the future, using OpenSSL would
probably be a better option.
This change ensures that instead of immediately deallocating the message
buffer after sending, we retain it in an acknowledgement wait queue
until an acknowledgement is received from the peer. This is necessary
to handle a behavior of the macOS kernel, which may prematurely
garbage-collect file descriptors contained within the message buffer
before the peer receives them.
The acknowledgement mechanism assumes messages are received in the same
order they were sent so, each acknowledgement message simply indicates
the count of successfully received messages, specifying how many entries
can safely be removed from the acknowledgement wait queue.
Similar to the existing macros for compile options and link options,
this macro wraps the command line definitions for swiftc in a way that
avoids warnings about conditional compilation flags not having values.
This commit removes the -Wno-unusued-private-field flag, thus
reenabling the warning. Unused field were either removed or marked
[[maybe_unused]] when unsure.
The goal here is to do something a bit smarter with the parsing here
than we do for properties. Instead of the JSON saying "here are the
values, and here are the keywords, and we can have up to 3", here we
place the syntax in the JSON directly (though currently broken up as
one string per option) and then we attempt to parse each one in
sequence. It's something we'll need eventually for `@property` among
other things.
...However, in this first pass, I've gone with the simplest option of
hard-coding the types instead of figuring them out properly. So there's
a PositivePercentage type and a UnicodeRangeTokens type, instead of
properly implementing the grammar for those in a generic way.
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.
Turns out we need this directory to pass to the -frontend command
for creating the interop header, so refactor the whole find module
to find it on each platform.
Add the proper annotations for the Cell and Cell::Visitor classes to be
visible in Swift. This lets us remove some OpaquePointer shinangians in
the Swift bindings.
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.
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.

In CMake 4.0, having a minimum policy version set to less than 3.5 is
a hard error at configure time. Add an override until the issue can be
resolved in vcpkg itself.
