            <title>[SERVER-78470] Prevent multi-false UpdateStage/DeleteStage from provoking yield after having already written </title>
                <link>https://jira.mongodb.org/browse/SERVER-78470</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-77116&quot; title=&quot;Checking shard version during restore can cause StaleConfig exception propagated for writes incorrectly&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-77116&quot;&gt;&lt;del&gt;SERVER-77116&lt;/del&gt;&lt;/a&gt; is built on the idea that multi=false updates/deletes should not yield after having performed one write, since upon restore the sharding placement could have changed and that would bubble up a StaleConfig exception. However, &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-77116&quot; title=&quot;Checking shard version during restore can cause StaleConfig exception propagated for writes incorrectly&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-77116&quot;&gt;&lt;del&gt;SERVER-77116&lt;/del&gt;&lt;/a&gt; missed one case: After performing the writes, UpdateStage/DeleteStage &lt;a href=&quot;https://github.com/mongodb/mongo/blob/4246c1a133315645fa996f412cf83732a8bb8e89/src/mongo/db/exec/update_stage.cpp#L573&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;restore their children stages&lt;/a&gt;, which can potentially fail due to WT failing with a WCE which needs to be handled by yielding. This undermines &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-77116&quot; title=&quot;Checking shard version during restore can cause StaleConfig exception propagated for writes incorrectly&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-77116&quot;&gt;&lt;del&gt;SERVER-77116&lt;/del&gt;&lt;/a&gt;. To solve this, we can skip restoring the children stages once UpdateStage/DeleteStage has reached EOF, since the children stages won&apos;t be used anymore.&lt;/p&gt;</description>
