            <title>[SERVER-16745] Force fetching documents on saveState() should be an exec stage</title>
                <link>https://jira.mongodb.org/browse/SERVER-16745</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Doc-locking storage engines must force fetch documents when they yield: yielding invalidates the OperationContext, which allows documents keyed by RecordIds in a query&apos;s WorkingSet to be deleted or modified. Force fetching prevents queries from seeing these modifications when they resume with a new OperationContext.&lt;/p&gt;

&lt;p&gt;Moving this force fetching logic into a query execution stage will allow us to expose diagnostics/statistics regarding force fetching via existing mechanisms (e.g. explain and the profiler).&lt;/p&gt;</description>

Closing as &quot;Gone Away&quot;, since there is no longer any work to do here.&lt;/p&gt;</comment>
