            <title>[SERVER-73390] Mitigate database version regression bug on drop database</title>
                <link>https://jira.mongodb.org/browse/SERVER-73390</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In order to mitigate the possibility of the defected interleaving described in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-70600&quot; title=&quot;dropDatabase DDL operation might complete with the old primary shard still believing that is the primary&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-70600&quot;&gt;&lt;del&gt;SERVER-70600&lt;/del&gt;&lt;/a&gt;, in case the database already exists we now enforce a clean-up for the primary and secondaries of the related database info (including the dbVersion) before passing to the second phase and flush the cache.&lt;/p&gt;

&lt;p&gt;However, there is still a small chance for the primary to recover the dbVersion if there is an stepdown during the execution of the 1st phase, as described in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-70600&quot; title=&quot;dropDatabase DDL operation might complete with the old primary shard still believing that is the primary&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-70600&quot;&gt;&lt;del&gt;SERVER-70600&lt;/del&gt;&lt;/a&gt;. Therefore &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-70600&quot; title=&quot;dropDatabase DDL operation might complete with the old primary shard still believing that is the primary&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-70600&quot;&gt;&lt;del&gt;SERVER-70600&lt;/del&gt;&lt;/a&gt; won&apos;t be  completely fixed until we will introduce the Recoverable critical section (&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-73391&quot; title=&quot;Use recoverable critical section for drop database&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-73391&quot;&gt;&lt;del&gt;SERVER-73391&lt;/del&gt;&lt;/a&gt;) &lt;/p&gt;</description>
