This CL adds subtypes (SyncJSDisposableStack and AsyncDisposableStack)
to JSDisposableStack as well as `await using` to the bytecode generator.
Currently async generators are broken and the fix is left as a TODO
in this CL. Also, exception handling (promise rejections) will be
completed in a follow up CL.

Temporal doesn't specify concrete era names, so tests shouldn't assert
for example that the era code of the current Gregorian era is `"ce"`. We
still want to validate the era names somehow however, so allow alternative
era names using the era codes from the "Intl era and monthCode" proposal.

Now that we don't have to deal with strings or objects as input to the
calendar ID or time zone ID parameter of constructors, we accept only the
data that actually goes into the internal slots.
This test should trip if an implementation forgets to perform the removals
that reached consensus in June 2024. (Although such an implementation
would technically comply with the specification, if you really need to do
that, please open an issue on the Temporal proposal repo rather than just
skiplisting this test.)
As in the previous commit, without custom calendars and time zones, some
functionality cannot be tested on implementations that don't have any
other calendars and time zones than iso8601 and UTC.
Some of the staging tests fall in this category. We take the opportunity
to port these into proper tests, in the intl402/ folder.
Previously getISOFields() was used to get the exact value of the
[[Calendar]] and [[TimeZone]] internal slots, as well as to get the
reference ISO year for PlainMonthDay and reference ISO day for
PlainYearMonth.
Use calendarId and timeZoneId for the former and toString() for the
latter.
Without custom calendars and time zones there are actually a bunch of
things that we now can't test on implementations that don't have non-ISO
calendars or non-UTC time zones. (Alternatively, we can say that these are
functionalities that those implementations don't have to implement.)
These are no longer possible without custom objects. Also add an exception
for calendar and timeZone properties in property bag observers so they are
not treated as objects.
Many tests tested some functionality while asserting that there were no
calls of calendar or time zone methods. We can continue testing the
functionality, but there are no more methods to call, so we can delete
those parts of the tests.
It's no longer possible to fake built-in time zones using custom objects.
So testing DST shifts will have to use real built-in time zones. Replace
TemporalHelpers.springForwardFallBackTimeZone with America/Vancouver (it
was modelled on the DST transitions in 2000) and
TemporalHelpers.crossDateLineTimeZone with Pacific/Apia (it was modelled
on the 2011 switch to the other side of the international date line.)
These tests have to move to the intl402/ folder since non-Intl-aware
implementations are allowed (but not required) to support any built-in
time zones other than UTC.
In many cases we created a TimeZone or Calendar instance from a built-in
time zone or calendar. These tests can be trivially adapted to just use
the string ID.
Some of the tests can be removed altogether since they deal with what
forms of input can be passed to ToTemporalTimeZoneSlotValue. Those are
tested on every method that takes a TimeZone as input.
Other tests are still relevant, but need to move to ZonedDateTime.p.equals
where the various quirks of time zone equality can still be tested. (Some
of these still will be removed in a following commit because they use
time zone objects.)
See: #2826
Temporarily replace them with getISOFields().calendar/timeZone just to
keep the tests running until we remove Calendar and TimeZone objects
altogether.

This PR proposes changes to existing test262 tests to allow them to pass under Hardened JavaScript (see Secure ECMAScript proposal and Hardened JavaScript). Moddable uses Hardened JavaScript for JavaScript runtimes on resource constrained embedded devices, including those targeted by ECMA-419.
The changes fall into four groups:
1. Replace use of new Date() with new Date(1970). Scripts running inside a Compartment cannot retrieve the current time, so new Date() throws but new Date(1970) succeeds. Very few tests need the current time, but instead simply need a Date instance.
2. Use Object.defineProperty instead of setting existing built-in properties directly, such as toString and toValue. In Hardened JavaScript, prototypes of built-in objects are frozen. Consequently, setting properties of an instance that exist on the prototype throw (Hardened JavaScript is always in strict mode).
3. Eliminate use of Math.random(). Scripts running inside a Compartment cannot generate random numbers. One test identified so far uses Math.random() in a way that can easily be replaced with a counter.
4. Narrow the scope of exception tests. Consider the following
assert.throws(TypeError, () => {
var s1 = new Date();
s1.toString = Boolean.prototype.toString;
s1.toString();
});
This test passes, but only because new Date() fails by throwing a TypeError. If the invocation of the Date constructor is resolved by (1) above, then the assignment to toString fails as per (2) above. The script should be modified as below to ensure that assert.throws only tests the intended statement, s1.toString(). The modified script tests the intended functionality and passes under Hardened JavaScript
var s1 = new Date(1970);
Object.defineProperty(s1, "toString", {
value: Boolean.prototype.toString
});
assert.throws(TypeError, () => {
s1.toString();
});
This is an initial PR to begin the process of adapting test262 for use with Hardened JavaScript. Further changes are expected, with the vast majority likely to fall into the four groups described above.
Thank you to gibson042, kriskowal, and erights for their advice on this work.
Following the upstream ECMA-402 change tested in the previous commit, add
test coverage for the corresponding functionality in Temporal. Fix one
test that was erroneous.
There is no such hidden constructor, it's the same as the hidden
AsyncFunction constructor. In other words:
```js
Object.getPrototypeOf(async () => {}).constructor ===
Object.getPrototypeOf(async function () {}).constructor
```
Also add a test to ensure that %AsyncFunction.prototype% is indeed the
prototype of an async arrow function.
Closes#4044.

New approach replaces ...Helper with CollectResize to make the tests easier to understand.
In particular:
- Replaced the need for '...Helper' abstractions with a more descriptive
function 'ResizeBufferMidIteration', which the .every method can call
directly.
- Moved 'let values' back outside of the loops, together with a function
definition 'ResizeBufferMidIteration' to persist the side effects that
'CollectValuesAndResize' has on 'values' but without having to define
this inside every loop.
+ So this reverts commit d9a2bac41f87f0964a43d34c6f349b6d78401633 and
+ this reverts commit 0bc2d66335671cac56912981b73c7900bf309cee.
- Added documentation.
* Documentation style change and remove accidental additions.
* Test that `nfOptions.roundingMode` for seconds / microseconds / nanoseconds is `"trunc"`
* Add license header
* Use `Intl.NumberFormat` instead of `testintl.js` harness
* Use correct harness

This covers an edge case that we hit, where 24 hours would not balance up
to one day in a 25-hour day if only largestUnit was specified, but would
erroneously balance up if rounding was also performed by specifying
smallestUnit.
In ZonedDateTime.p.since/until, it's possible for AddDateTime to hit the
limit if the rounding increment is very high, even if the resulting
rounded duration isn't outside of the limit. Add a test covering this
case.
This should produce all the same results (except for a change to weeks
balancing in round(), which is now more consistent with since()/until())
but leads to different observable user code calls.

Previously, this test checked for a particular format. This would break

(There's an existing comment which suggests that this should already have
been testing formatToParts().)
For each Temporal type, add a test (which should not be sensitive to the
exact locale format) that ensures dateStyle affects the output, for a
Gregorian and non-Gregorian calendar.
See https://github.com/tc39/proposal-temporal/issues/2058
It was previously not tested what options value a custom calendar's
dateFromFields() method would be called with, when called from the
toPlainDate() method of PlainYearMonth/PlainMonthDay.
See tc39/proposal-temporal#2803
These tests were supposed to test an invalid ISO string being used as the
`calendar` property in a property bag. Instead they were testing being
used as an invalid ISO string directly where a PlainDate input was needed.
(That is also already covered elsewhere.)
Due to overlooked copy-paste errors we were creating the wrong type of
instance in these tests, and therefore testing the wrong method.
(Add blank line for consistency with the other instances of these tests.)
After rounding relative to a ZonedDateTime, we have to potentially adjust
for DST. With a time zone providing nonsensical values, the duration may
go out of range.
See: tc39/proposal-temporal#2801
This test isn't testing what the assertion message previously said it was
testing. The integer is allowed to be unsafe, but in this case its
float64-representation is out of range.
See: https://github.com/tc39/proposal-temporal/issues/2785
With test cases kindly provided by Anba, this adds test coverage for the
abrupt completion in the last step of DifferenceTemporalPlainDateTime,

See: https://github.com/tc39/proposal-temporal/issues/2783
normalized-time-duration-to-days-range-errors.js tests for several error
cases in the AO NormalizedTimeDurationToDays. Adding assertion messages
helps to know which one you are debugging.
As per IETF, annotation keys may only consist of lowercase letters,
dashes, and digits, and an optional leading underscore. Uppercase letters
are non-syntactical. Add tests covering this.
These test cases ensure that DST disambiguation does not take place on
intermediate values that are not the start or the end of the calculation.
Note that NormalizedTimeDurationToDays is no longer called inside
Temporal.Duration.prototype.add/subtract, so a few tests can be deleted.
Other tests need to be adjusted because NormalizedTimeDurationToDays is
no longer called inside Temporal.ZonedDateTime.prototype.since/until via
DifferenceZonedDateTime, although it is still called as part of rounding.
In addition, new tests for the now-fixed edge case are added, and for the
day corrections that can happen to intermediates.

3. And finally `Create{Shared}ByteDataBlock` is called.
Time zone identifiers supported by ICU, but which aren't valid IANA
identifiers.
Implementations not supporting ECMA-402 are theoretically allowed to
support these identifiers, so the tests have to go into the "intl402"
directory.
This adds tests specifically for every kind of case that changes due to
the tweak to the date difference algorithm: differences from a longer
month to a shorter month, when the months are adjacent, in the same year
but not adjacent, and in different years.
Also adds tests for a case that does *not* change, but would trip on an
incorrectly implemented algorithm: when the intermediate months value
falls at the end of February.
There was incidental coverage of the change to the date difference
algorithm in other tests. Those are adjusted, as well.
Normative change: https://github.com/tc39/proposal-temporal/pull/2759

Adapts the tests that checked arbitrarily long loops, to now check that an
exception is thrown if the loop would happen.
Adds tests that exercise the newly added checks on return values of
getPossibleInstantsFor and getOffsetNanosecondsFor that limit UTC offset
shifts to 24 hours or less.
Also updates some step numbers in related tests.
The existing tests didn't cover some edge cases where implementations
have to compute the exact result of `numerator / denominator`, where at
least one of `numerator` and `denominator` can't be exactly represented
by an IEEE-754 double precision floating point value.
"precision-exact-mathematical-values-5.js" gets added in #3961, so the
new tests from this commit start at "precision-exact-mathematical-values-6.js".
NormalizedTimeDurationToDays can no longer loop indefinitely, because at
a certain point we will hit the upper bound of MAX_SAFE_INTEGER, so rename
the test to reflect that it can loop an arbitrary but limited number of
times.
Add a test for the RangeError condition in NormalizedTimeDurationToDays
when the time zone calculates a day length that is not a safe integer
number of nanoseconds.
While editing these tests, rename them to match the current name of the AO
and make sure the step numbers are up to date. (Normally I wouldn't care
so much about that, but these tests can be pretty confusing so it's good
to be able to refer to the spec text.)
Adapts or removes tests that relied on creating durations that are now out

In order to fixtc39/proposal-temporal#2563, we added invocations of
BalanceDurationRelative after some invocations of RoundDuration. These

See https://github.com/tc39/proposal-temporal/issues/2563
The old behaviour was encoded in one test in staging, but the behaviour of
largestUnit in duration rounding has changed since that test was written.
Therefore I'm assuming that toString() should've been updated when that
happened.

These tests were incorrect, in checking for a RangeError when only one of
the era/eraYear fields were given. From CalendarResolveFields:
"The operation throws a *TypeError* exception if the properties of
_fields_ are internally inconsistent within the calendar or insufficient
to identify a unique instance of _type_ in the calendar."
Built-in non-ISO calendars require either monthCode/day, or month/day plus
some form of year specification.
This adds test coverage for each of the categories listed in
https://github.com/tc39/proposal-temporal/issues/2664, of which some must
currently reside in the test/intl402/ folders.
We'll do this for now, then separately work on migrating all of the tests
that require a non-ISO8601 calendar but aren't dependent on it being any
particular calendar.
In the AO DisambiguatePossibleInstants, a PlainDateTime instance is passed
to user code. This instance should have the built-in ISO 8601 calendar.
Here are some tests that ensure it does.
See tc39/proposal-temporal#2671.
In PlainYearMonth arithmetic, we need to find the end of the month when
adding a negative duration or subtracting a positive one. This end of the
month can be out of range.
Test case based on one provided by Anba. See issue:
https://github.com/tc39/proposal-temporal/issues/2700
Two issues:
1. There was a typo, the first `gen` should have been `genFn`.
2. And the last `toString` result should be `'[object Generator]'`,
because `Object.getPrototypeOf(gen) == genFn.prototype`. And the
`@@toStringTag` property of `genFn.prototype` is inherited from
`Generator.prototype[@@toStringTag]`.
That also means the "iterator-helpers" flag isn't needed for this test.
For the statement level test, the inner class name is not initialized
at the time the decorators evaluate, resulting in a ReferenceError
that the declaration can not be accessed prior to initialization.
Similar, non-decorator code, like:
class C {
static dec() {}
static {
this.x = C.dec();
class C {}
}
}
also results in a ReferenceError.
For the expression level test, the var C is undefined at the time the
decorators are evaluated, resulting in TypeError while trying to access
a member of undefined.
Similar, non-decorator code, like:
var C = class {
static f() {};
static {
this.x = C.f();
}
}
also results in a TypeError.
This removes several loopholes where it was possible to return particular
values from user calls that would cause infinite loops, or calculate
zero-length days.
