            <title>[SERVER-69463] Refresh the locking requirements in the source files documentation</title>
                <link>https://jira.mongodb.org/browse/SERVER-69463</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Some of these have gone stale. Many of them use ambiguous terms like &quot;X lock&quot; which seems to predate WiredTiger or the introduction of intent locks. Some staleness I&apos;ve found:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/c348c4a18608c9f7631192ba0abc13e5ed7c7417/src/mongo/db/catalog/database_holder.h#L80&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;DatabaseHolder::openDb()&lt;/a&gt; reads &quot;must be called with the database locked in X-mode&quot;, however it actually requires a MODE_IX lock.&lt;/li&gt;
	&lt;li&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/c348c4a18608c9f7631192ba0abc13e5ed7c7417/src/mongo/db/catalog/database.h#L109&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Database::dropCollection()&lt;/a&gt; reads &quot;the caller should hold a DB X lock&quot; and that contradicts the &lt;a href=&quot;https://www.mongodb.com/docs/manual/reference/method/db.collection.drop/#resource-locking&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;documentation&lt;/a&gt; stating that dropCollection hasn&apos;t taken a strong db lock since 4.2.&lt;/li&gt;
&lt;/ul&gt;
