The relevant type of ArrayBuffer DataBlock is now a struct containing
both a ByteBuffer* and a size_t size, and not just a ByteBuffer*, with
the size being that of the ByteBuffer. This type of DataBlock is only
used for WebAssembly.Memory (see commit 4fd43a8f96), meaning this
change won't affect any other code. This change is required to pass one
WPT subtest in wasm/jsapi/memory/grow.any.html, since old fixed-length
SharedArrayBuffers after a WebAssembly.Memory growth should keep their
length, while the new buffer after the growth will have the updated
length.
This reverts commit c14173f651. We
should only annotate the minimum number of symbols that external
consumers actually use, so I am starting from scratch to do that
This will allow structured deserialization in LibWeb to create shared
buffers without having to go through CreateSharedByteDataBlock. That
will let us pass in the underlying ByteBuffer, rather than having to
allocate a second buffer via CreateSharedByteDataBlock and memcpy the
data into it.
Resulting in a massive rename across almost everywhere! Alongside the
namespace change, we now have the following names:
* JS::NonnullGCPtr -> GC::Ref
* JS::GCPtr -> GC::Ptr
* JS::HeapFunction -> GC::Function
* JS::CellImpl -> GC::Cell
* JS::Handle -> GC::Root
