064ed8279e LibJS: Support deleting local variables with operator delete 
To make this cleaner i also moved the logic into Reference::delete_.

3fdad563e2 LibJS: Never omit setter/getter attributes in accessor descriptor object 
These should not be omitted, an accessor with out getter or setter still
yields an undefined for the attribute in its descriptor object.

8c964ef9f8 LibJS: Fix get_own_property_descriptor_object() field name order

4ba2eb8fe5 LibJS: Cache generated bytecode for ScriptFunction 
It's silly to generate new bytecode every time you call a function.
Let's just cache the code instead. :^)

80b1604b0a LibJS: Compile ScriptFunctions into bytecode and run them that way :^) 
If there's a current Bytecode::Interpreter in action, ScriptFunction
will now compile itself into bytecode and execute in that context.

This patch also adds the Return bytecode instruction so that we can
actually return values from called functions. :^)

Return values are propagated from callee to caller via the caller's
$0 register. Bytecode::Interpreter now keeps a stack of register
"windows". These are not very efficient, but it should be pretty
straightforward to convert them to e.g a sliding register window
architecture later on.

This is pretty dang cool! :^)

f9395efaac LibJS: Use ToPropertyKey in Object.getOwnPropertyDescriptor 
The specification requires this. (And the current usage of
PropertyName::from_value is invalid since integers are not allowed in
this context)

1c51edb639 LibJS: Add missing length field to Symbol.prototype[Symbol.ToPrimitive] 
Since the argument was missing Attribute::Configurable was used as the
length, which resulted in incorrect attributes being applied.

61c56e75f4 LibJS: Flatten Shape::property_table() 
In the common case, we take the early return in ensure_property_table()
so let's make sure it gets inlined into property_table().

d24f4462c7 LibJS: Add VM::dump_backtrace() 
This is just a simple helper that dumps the current VM call stack
to the debug console. I find myself rewriting this function over and
over, so let's just have it in the tree.

3dfd450f2d LibJS: Use Array::create() length arg in favor of set_array_like_size() 
This way we don't bypass the maximum length check.
 2021-06-06 23:27:47 +01:00
Linus Groh
1c906b07a4 LibJS: Add length parameter to Array::create() 
This is now a bit closer to the spec's 10.4.2.2 ArrayCreate - it will
throw a RangeError if the requested length exceeds 2^32 - 1, so anyone
passing in a custom value (defaults to zero for same behaviour as
before) will need an exception check at the call site.

60e70e5ee4 LibJS: Add Date.setUTC{Date, Month, Hours, ...}() aliases 
These are a bit hacky, since they are supposed to be separate methods,
but since serenity only supports UTC currently, they are equivalent.

46214f0657 LibJS: Store Date milliseconds as signed to support negative offsets

59034554a4 LibJS: Account for differences in month representations (0-11 vs 1-12) 
Since DateTime stores months as 1 to 12, while JS accepts months as
0 to 11, we have to account for the difference (by subtracting or
adding 1) where appropriate.

3eb05d9413 LibJS: Stub out Date.prototype.getTimezoneOffset() 
We only support UTC currently, so this always returns 0 as long as the
date is not invalid.

44926b3f80 LibJS: Ignore arguments in Date's constructor when called as a function 
Since theres no way to drop the arguments before the call to the
constructor (or to signal to the constructor that it was not called
directly), we simply reuse the code for the no arguments provided
special case. (And to prevent code duplication, the code was extracted
into the separate static function Date::now(GlobalObject&).

ba9d3bc38c LibJS: Create 1970-01-01 00:00:00 local time Date for invalid ctor call 
When using Core::DateTime::from_timestamp(0) the resulting Date is
1970-01-01 00:00:00 in UTC, which might be something different in local
time - this is incorrect and relevant as invalid Dates can be made valid
later on.

8d7ec28924 LibJS: Remove String.prototype.length

non-enumerable, non-configurable property on the StringObject instead.

d255e6892b LibJS: Update NumberPrototype's this_number_value() to take a Value 
This is now about as close to the spec as it gets - instead of querying
the |this| value inside of the function, we now pass it in from the
outside.
Also get rid of the oddly specific error messages, they're nice but
pretty inconsistent with most others. Let's prefer consistency and
simplicity for now.

Other than that, no functionality change.

Linus Groh
cd12b2aa57 LibJS: Implement the RequireObjectCoercible abstract operation 
Throws an exception if the given value is nullish, returns it otherwise.
We can now gradually replace such manual checks with this function where
applicable.

This also has the advantage that the somewhat useless "ToObject on null
or undefined" will be replaced with "null cannot be converted to an
object" or "undefined cannot be converted to an object". :^)
