Iterator is not closed when the "resolve" capability returns an abrupt
|
|
completion.
|
|
info: |
|
|
1. Let C be the this value.
|
|
[...]
|
|
3. Let promiseCapability be ? NewPromiseCapability(C).
|
|
[...]
|
|
7. Let result be PerformPromiseAll(iteratorRecord, C, promiseCapability).
|
|
8. If result is an abrupt completion, then
|
|
a. If iteratorRecord.[[Done]] is false, let result be
|
|
IteratorClose(iterator, result).
|
|
b. IfAbruptRejectPromise(result, promiseCapability).

6. Repeat
|
|
[...]
|
|
d. If next is false, then
|
|
[...]
|
|
iii. If remainingElementsCount.[[Value]] is 0, then
|
|
1. Let valuesArray be CreateArrayFromList(values).
|
|
2. Perform ? Call(resultCapability.[[Resolve]], undefined, «
|

valuesArray »).

25.4.1.1.1 IfAbruptRejectPromise
|
|
|
|
IfAbruptRejectPromise is a short hand for a sequence of algorithm steps that
|
|
use a PromiseCapability Record. An algorithm step of the form:
|
|
|
|
1. IfAbruptRejectPromise(value, capability).
|
|
|
|
means the same thing as:
|
|
|
|
1. If value is an abrupt completion, then
|
|
a. Perform ? Call(capability.[[Reject]], undefined, « value.[[Value]] »).
|
|
b. Return capability.[[Promise]].
|
|
2. Else if value is a Completion Record, let value be value.[[Value]].
