            <title>[SERVER-73212] Remove collection locks from sharding index catalog observers</title>
                <link>https://jira.mongodb.org/browse/SERVER-73212</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently in the sharding&apos;s op observer when handling sharding&apos;s index catalog we&apos;re holding collection locks &lt;a href=&quot;https://github.com/10gen/mongo/blob/368ae38dea1386062c6c7a1591c469c7bc9d56fe/src/mongo/db/s/shard_server_op_observer.cpp#L538-L611&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;inside the onCommit&apos;s handler&lt;/a&gt;, this could cause the following behavior: if the OperationContext is interrupted, then attempting to acquire a lock would throw an exception and lead to a server crash because onCommit() handlers are noexcept.&lt;/p&gt;

&lt;p&gt;We should move the collection acquiring, like for example, to the &lt;a href=&quot;https://github.com/10gen/mongo/blob/368ae38dea1386062c6c7a1591c469c7bc9d56fe/src/mongo/db/s/global_index_ddl_util.cpp&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;sharding index catalog ddl util&lt;/a&gt; inside each &lt;em&gt;writeConflictRetry&lt;/em&gt; in resource id order.&lt;/p&gt;</description>
