Store parser errors, source range filenames, source code filenames,
module source, and Rust parser errors as UTF-16 where they flow back
into JavaScript-visible strings. Keep byte-oriented source buffers
byte-backed.
Remove temporary PrimitiveString, ByteString, and UTF-8 detours from
JSON, RegExp, module debug logging, print formatting, and tests.
Produce JS-visible string results as UTF-16 at their source, including
numeric formatting, BigInt and BigFraction formatting, URI encoding,
console formatting, parser errors, regular expression errors, Intl and
Temporal records, LibUnicode locale boundaries, and LibWeb bindings.
Handle fractional radix formatting through the UTF-16 builder view.
Thread UTF-16 string input through JSON, script parsing, Date parsing,
Intl option parsing, Temporal parsing, and the helper library boundaries
that feed those parsers. Preserve ASCII fast paths where the source data
is known to be ASCII.
Move the remaining LibJS primitive string users to UTF-16 views and
strings. Remove the primitive string UTF-8 accessors and byte-string
coercion paths so new callers cannot rely on the old storage model.
Keep primitive string storage in Utf16String and remove the UTF-8
storage path from PrimitiveString. ASCII strings still use compact
Utf16String ASCII storage, while UTF-16 becomes the only owned
representation.
Port more UTF-16 string construction sites to Utf16StringBuilder.
This covers JSON serialization, URI escaping, RegExp replacement, date
and Temporal formatting, Uint8Array hex conversion, and stack string
formatting. Keep byte-oriented debug, bytecode, parser, and print
plumbing on StringBuilder.
Add a checked JS string length sum helper and use it for accumulation
paths that append JS-observable string pieces.
Port straightforward JS string construction sites to Utf16StringBuilder.
Make ASCII appends explicit with append_ascii(), and leave byte-output,
formatted-output, and printer plumbing on StringBuilder where that API
still matches the caller.
Add a small checked JS string length product helper. Use it for
String.prototype.repeat() before constructing the repeated result. Keep
the maximum string length policy in LibJS while allowing the UTF-16
builder to remain purpose-built and infallible. Cover overflow from the
final repeated code-unit length in the repeat tests.
Enable -Wexit-time-destructors for all in-tree library targets and
update process-lifetime library statics so they no longer register
exit-time destructors. Long-lived caches, lookup tables, singleton
registries, and generated constants now use NeverDestroyed or leaked
references where the data is intended to live until process exit.
Update LibWeb, LibLine, and the binding generators so regenerated
sources follow the same rule instead of reintroducing destructed
statics.
Similar to GC::Root<T>, make GC::RootVector<T> constructible without
explicitly passing a Heap.
This is implemented by having RootVectorBase use GC::Heap::the() for
heap-free construction.
Keep the primitive string that segment() creates alongside the UTF-16
buffer used by LibUnicode. Segment data objects can then return lazy
Substring instances for "segment" and reuse the original
PrimitiveString for "input" instead of copying both strings.
Add a rope-backed UTF-16 segmenter test that exercises both
containing() and iterator results.
Intermediate classes in the initialize() chain set up prototypes and
define properties. Forgetting to call Base::initialize() in any
override would silently skip that setup.
This is an editorial change in the Temporal proposal. See:
https://github.com/tc39/proposal-temporal/commit/1fdf09a
Note that the integer limits in the above commit are in spec headers,
which we don't copy to our implementation.
This first pass only applies to the following two cases:
- Public functions returning a view type into an object they own
- Public ctors storing a view type
This catches a grand total of one (1) issue, which is fixed in
the previous commit.
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
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
