            <title>[SERVER-43342] createCollection can run concurrently with two phase dropDatabase</title>
                <link>https://jira.mongodb.org/browse/SERVER-43342</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Two phase dropDatabase &lt;a href=&quot;https://github.com/mongodb/mongo/blob/2f21c91f3c72be9ecea67c1d391c713b05d97a29/src/mongo/db/catalog/drop_database.cpp#L232-L244&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;releases locks&lt;/a&gt; while waiting for collection drops to majority replicate before replicating a drop database oplog entry.&lt;/p&gt;

&lt;p&gt;A &lt;a href=&quot;https://github.com/mongodb/mongo/blob/2f21c91f3c72be9ecea67c1d391c713b05d97a29/src/mongo/db/catalog/drop_database.cpp#L152&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;flag is set&lt;/a&gt; such that operations which should not run inbetween have a means to do so.&lt;/p&gt;

&lt;p&gt;Due to how secondaries process a &lt;tt&gt;dropDatabase&lt;/tt&gt; oplog entry, collections created inside this window can result in losing majority committed writes.&lt;/p&gt;</description>

The only bug was &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-43352&quot; title=&quot;restartCatalog expects listDatabases to include empty databases&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-43352&quot;&gt;&lt;del&gt;SERVER-43352&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;</comment>
