Previously, constructing a `UnsignedBigInteger::from_base()` could
produce an incorrect result if the input string contained a valid
Base36 digit that was out of range of the given base. The same method
would also crash if the input string contained an invalid Base36 digit.
An error is now returned in both these cases.
Constructing a BigFraction from string is now also fallible, so that we
can handle the case where we are given an input string with invalid
digits.
This is to allow future changes to do cross-process MessagePorts in an
implementation-agnostic way. Add some tests for this behavior.
Delivering messages that were posted to a MessagePort just before it was
transferred is not yet implemented still.
Use a LocalSocket to represent the connection between two message ports.
The concept of the port message queue is still missing, however. When
that concept is implemented, the "steps" in step 7 of the message port
transfer steps will need to send the serialized data over the connected
socketpair and run in the event loop of the process that holds onto the
other side of the message port. Doing this should allow centralizing the
behavior of postMessage for Window, MessagePorts and Workers.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:
$ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \
Meta Ports Ladybird Tests Kernel)
$ perl -pie 's/\bDeprecatedString\b/ByteString/g;
s/deprecated_string/byte_string/g' $xs
$ clang-format --style=file -i \
$(git diff --name-only | grep \.cpp\|\.h)
$ gn format $(git ls-files '*.gn' '*.gni')
Also trap the invalid object index inserted for transferred values in
deserialization. In the future we should avoid inserting that
placeholder value in the data stream at all.
ArrayBuffer no longer stores a plain ByteBuffer internally, but a
DataBlock instead, which encapsulated the ByteBuffer together with
information if it is shared or not.
Call them from the helpers for strings. We'll have other object classes
soon that need to serialize ByteBuffers, so let's take advantage of the
encoding scheme we are already using for Strings.
We skip serializing any of the internal state of the Regex<ECMA262>
object, because that state is all computable from the input pattern
and flags. If it turns out that this is really, really slow, we can add
some optimizations to serialize more of the regex parse result.
If we serialize a string followed by some other object, the deserialize
helper would just happily keep appending bytes to the string until the
end of the serialization buffer. Avoid doing that by checking the string
length for figuring out when the string actually ends.
Stop worrying about tiny OOMs. Work towards #20449.
While going through these, I also changed the function signature in many
places where returning ThrowCompletionOr<T> is no longer necessary.
This patch changes the way StructuredSerializeInternal() serialize
strings by storing four bytes into a 32-bit entry, instead of one code
point per 32-bit entry.
StructuredDeserialize() has also been changed to deserialize strings by
the same ruleset.
This implementation only works for cloning Numbers, and does not try to
do all the spec steps for structured serialize and deserialize.
