            <title>[SERVER-79070] Executor shutdown can cause  async_rpc::getAllResponsesOrFirstErrorWithCancellation to return BrokenPromise</title>
                <link>https://jira.mongodb.org/browse/SERVER-79070</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&#160;async_rpc::getAllResponsesOrFirstErrorWithCancellation takes a vector of future-like types and returns a single future that is ready when all of the input futures are ready. To do so, it chains a callback to defined &lt;a href=&quot;https://github.com/10gen/mongo/blob/3ad4a5ff13f42610bfeb8f34e512a72d172d2c37/src/mongo/executor/async_rpc_util.h#L199&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt; to each input future, the last of which to run will emplace a value in a promise that readies the output-future of the entire function. However, the callback is chained via getAsync &lt;a href=&quot;https://github.com/10gen/mongo/blob/3ad4a5ff13f42610bfeb8f34e512a72d172d2c37/src/mongo/executor/async_rpc_util.h#L121&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;, which means that if the input future-like types are ExecutureFuture, they may not run in the case of executor shutdown. This means the promise for the output-future will eventually be destroyed without providing a value to the future, resulting in a BrokenPromise error propogating out.&#160;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;This is very similar to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-54735&quot; title=&quot;Executor shutdown can cause AsyncTry-until to set its result with ErrorCodes::BrokenPromise&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-54735&quot;&gt;&lt;del&gt;SERVER-54735&lt;/del&gt;&lt;/a&gt; and some other related bugs, and can probably be handled either in the same way, or simply by chaining the callback via unsafeToInlineFuture.&#160;&lt;/p&gt;</description>
