            <title>[SERVER-79401] Investigate interactions between multi-document transactions and assertReadConcernSupported</title>
                <link>https://jira.mongodb.org/browse/SERVER-79401</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The &lt;a href=&quot;https://github.com/mongodb/mongo/blob/dd7f5999cdbcbe85211889e060f884cffad92acb/src/mongo/db/db_raii.cpp#L232&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;assertReadConcernSupported&lt;/a&gt; method is only used by the &lt;tt&gt;AutoGetCollectionForRead*&lt;/tt&gt; family of AutoGetters. As a result, normal AutoGetCollection calls are exempted from that check.&lt;/p&gt;

&lt;p&gt;For &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-77507&quot; title=&quot;Integrate acquisitions into Find&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-77507&quot;&gt;&lt;del&gt;SERVER-77507&lt;/del&gt;&lt;/a&gt; we integrated the assertion check into collection acquisitions and had to exempt writes from performing that check. Ideally, we would want to expand that assertion to everyone but doing so leads to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/522ffb8ad30426d239b989a229e992b2eeebf8e0/src/mongo/db/transaction/transaction_participant.cpp#L464&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this code&lt;/a&gt; causing issues. The transaction is writing to the &lt;tt&gt;config.transactions&lt;/tt&gt; collection with the original read concern settings, leading to &lt;a href=&quot;https://github.com/10gen/mongo/blob/dd7f5999cdbcbe85211889e060f884cffad92acb/src/mongo/db/db_raii.cpp#L256&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this assertion&lt;/a&gt; being hit.&lt;/p&gt;</description>
