            <title>[SERVER-54408] Rewrite AsyncTry-until to not use future recursion</title>
                <link>https://jira.mongodb.org/browse/SERVER-54408</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Due to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-53500&quot; title=&quot;Investigate making nested futures equivalent to chained continuations&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-53500&quot;&gt;SERVER-53500&lt;/a&gt;, using the AsyncTry-until utility can lead to an invariant being hit in unpredictable places. Since &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-53500&quot; title=&quot;Investigate making nested futures equivalent to chained continuations&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-53500&quot;&gt;SERVER-53500&lt;/a&gt; will be difficult to diagnose and potentially unfeasible to fix, so in the meantime we can rewrite the AsyncTry utility to not use recursive futures, which are responsible for hitting the invariant. I&apos;ve done a POC and confirmed this fixes the issues seen by &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-50656&quot; title=&quot;Add cancelation support to WaitForMajorityService using CancelationTokens&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-50656&quot;&gt;&lt;del&gt;SERVER-50656&lt;/del&gt;&lt;/a&gt; on debug builds.&lt;/p&gt;</description>
