Aside from the obvious performance benefits, this will allow us to
properly handle dictionary types. (whose dictionary-ness is only known
at build-time)
Much of the rest of the overload resolution algorithm steps can (and
should) be evaluated at build-time as well, but this is a good first
step.
When wrapping dictionary members, generate_wrap_statement was called
with the pattern "auto {} = ...", where "..." was determined based on
the variable's type. However, in generate_wrap_statement, if a type is
nullable it generates an if statement, so this would end up generating
something along the lines of
if (!retval.member.has_value()) {
auto wrapped_member0_value = JS::js_null();
} else {
auto wrapped_member0_value = JS::Value(...);
}
...which makes the declaration inaccessible. It now generates the same
code, but the "auto" declaration (now an explicit JS::Value declaration)
is outside of the if-statement.
After d2c7e1ea7d, there is now only one
user of LibPublicSuffix - the URL sanitation utility within LibWebView.
Rather than having an entire library for the small Public Suffix data
accessor, merge it into LibWebView.
That API came from a mistake in the IDL compiler, where reflected
nullable attributes would try to call set_attribute(name, null).
This commit fixes the mistake in the IDL generator, and removes the
meaningless API.
This commit removes DeprecatedString's "null" state, and replaces all
its users with one of the following:
- A normal, empty DeprecatedString
- Optional<DeprecatedString>
Note that null states of DeprecatedFlyString/StringView/etc are *not*
affected by this commit. However, DeprecatedString::empty() is now
considered equal to a null StringView.
These functions all have a very common case that can be dealt with a
very simple inline check, often avoiding the need to call an out-of-line
function. This patch moves the common case to inline functions in a new
ValueInlines.h header (necessary due to header dependency issues..)
8% speed-up on the entire Kraken benchmark :^)
For example, the locale "fr-FR" will have the preferred hour cycle list
of "H hB", meaning h23 and h12-with-day-periods. Whether date-times are
actually formatted with day-periods is up to the user, but we need to
parse the hour cycle as h12 to know that the FR region supports h12.
This bug was revealed by LibJS no longer blindly falling back to h12 (if
the `hour12` option is true) or h24 (if the `hour12` option is false).
We currently only return primary time zones, i.e. time zones that are
not a Link. LibJS will require knowledge of Link entries, and whether
each entry is or is not a Link.
This function must return true if the object may intercept and customize
access to indexed properties (properties where the property name is a
non-negative integer.)
This will be used to implement fast path optimizations for array-like
accesses in subsequent commits.
Which pretty much needs to be done together due to the amount of places
where they are compared together.
This also involves porting over StackOfOpenElements over to FlyString
from DeprecatedFly string to prevent a gazillion calls to
`.to_deprecated_fly_string` calls in HTMLParser.
This will effectively allow us to use C++ code as an input for the
compiler. This would be useful for testing, since otherwise we would
have had to specify tests as a spec-like XML, which is not exactly the
most developer-friendly experience.
