Daniel Sun resolved GROOVY-12721.
---------------------------------
Resolution: Fixed
Fixed in https://github.com/apache/groovy/pull/3255 (master bc25deb53b48 /
776a3d511059) and cherry-picked to GROOVY_6_0_X (de781acd629c / 37183e18ef5a).
> Awaitable.all, any, first and allSettled should accept a single list of
> sources

> Key: GROOVY-12721
> URL: https://issues.apache.org/jira/browse/GROOVY-12721
> Project: Groovy
> Issue Type: Improvement
> Affects Versions: 6.0.0
> Reporter: Scott Murphy Heiberg
> Assignee: Daniel Sun
> Priority: Major
> Fix For: 6.x, 7.x

>
> {{Awaitable.all}}, {{any}}, {{first}} and {{allSettled}} take {{Object...
> sources}}. A caller holding a list of tasks, the usual shape when the tasks
> come out of {{collect}}, has to spread it: {{Awaitable.allSettled(*tasks)}}.
> Passing the list itself compiles and fails at run time with a message about
> the list's class:
> {code:groovy}
> def tasks = ['a', 'b', 'c'].collect { m -> async { fetch(m) } }
> def results = await Awaitable.allSettled(tasks)
> {code}
> {noformat}
> IllegalArgumentException: No Awaitable adapter found for type:
> java.util.ArrayList. Register an AwaitableAdapter via ServiceLoader or
> AwaitableAdapterRegistry.register().
> {noformat}
> JavaScript's {{Promise.all}}, {{allSettled}}, {{any}} and {{race}} take an
> iterable, so this is the form people, and the models trained on them, write
> first. A single argument that is a {{Collection}} has no other meaning today,
> since a collection is never awaitable, so the combinators can take it as the
> list of sources.
> Proposal: in {{AwaitCombinators}}, when {{sources}} has one element and it is
> a {{Collection}}, use its elements; the empty and null checks of {{any}} and
> {{first}} then apply to those elements. {{Awaitable.all(*tasks)}} keeps
> working. A sentence in the combinator summary of core-async-await.adoc and in
> the {{@param sources}} Javadoc.
> Found while scoring Groovy 6.0.0 code written by a language model: with the
> Groovy documentation available to it through a tool, GPT-6 still wrote the
> list form.
