            <title>[SERVER-47084] Support AutoGetCollectionForRead-like readSource validation after query yielding</title>
                <link>https://jira.mongodb.org/browse/SERVER-47084</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We have code to check some&#160;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/d55ce1b7ae2127d257138066490e60cf9035ee24/src/mongo/db/db_raii.cpp#L122-L251&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;preconditions&lt;/a&gt; before taking locks and acquiring a snapshot in &lt;tt&gt;AutoGetCollectionForRead&lt;/tt&gt;. But these preconditions are not checked &lt;a href=&quot;https://github.com/mongodb/mongo/blob/8ccaacce937ae51deef27c41e977aca0511fb338/src/mongo/db/query/plan_yield_policy.cpp#L210&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;after we yield&lt;/a&gt; in &lt;tt&gt;PlanExecutor&lt;/tt&gt;. And in general, the use of &lt;tt&gt;AutoGetCollectionForRead&lt;/tt&gt; seems error-prone after lock yields as the guarantees the RAII type gives might be lost after query yieldings.&lt;/p&gt;

&lt;p&gt;We have &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-44529&quot; title=&quot;Re-acquiring locks after a yield and step down results in wrong parameters on recoveryUnit&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-44529&quot;&gt;&lt;del&gt;SERVER-44529&lt;/del&gt;&lt;/a&gt; and &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-46721&quot; title=&quot;Step up may cause reads at PIT with holes after yielding&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-46721&quot;&gt;&lt;del&gt;SERVER-46721&lt;/del&gt;&lt;/a&gt; that describe a similar but slightly different problem of the undesired behaviors of &lt;tt&gt;AutoGetCollectionForRead&lt;/tt&gt; after yields.&lt;/p&gt;

&lt;p&gt;I think it is better to come up with a more generic solution so that the guarantees of &lt;tt&gt;AutoGetCollectionForRead&lt;/tt&gt; can still hold across yields.&lt;/p&gt;</description>
