            <title>[SERVER-72235] Avoid the usage of dropCollectionEvenIfSystem() outside of resharding code </title>
                <link>https://jira.mongodb.org/browse/SERVER-72235</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;As part of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-69603&quot; title=&quot;Do not report drop events as part of shardCollection&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-69603&quot;&gt;&lt;del&gt;SERVER-69603&lt;/del&gt;&lt;/a&gt;, the &lt;tt&gt;ensureCollectionDropped()&lt;/tt&gt; function of &lt;a href=&quot;https://github.com/mongodb/mongo/commit/22afc187e2a5ed450cf608458393830eb40b913a#diff-9e131ec0f6ddb8a09f59898d233f07dc242d1c85d0433577ac125845dd695f43L73-L94&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;src/mongo/db/s/resharding/resharding_data_copy_util.cpp&lt;/a&gt; was promoted  &lt;a href=&quot;https://github.com/10gen/mongo/blob/fc16835302e453b2409481cad05ff4485edeec1b/src/mongo/db/s/sharding_ddl_util.cpp#L803-L805&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;to a generic sharding utility&lt;/a&gt; (&lt;tt&gt;sharding_ddl_util::ensureCollectionDroppedNoChangeEvent()&lt;/tt&gt;) to drop both user and system collections.&lt;/p&gt;

&lt;p&gt;As &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-71880&quot; title=&quot;_shardsvrDropCollectionParticipant with fromMigrate=true does not abort index builds&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-71880&quot;&gt;&lt;del&gt;SERVER-71880&lt;/del&gt;&lt;/a&gt; demonstrated, such approach was flawed, since the utility function &lt;a href=&quot;https://github.com/10gen/mongo/blob/fc16835302e453b2409481cad05ff4485edeec1b/src/mongo/db/s/sharding_ddl_util.cpp#L822-L823&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;contained a method&lt;/a&gt; of the local catalog that cannot be safely used outside the context of a resharding operation.&lt;/p&gt;

&lt;p&gt;To avoid similar issues in the future, &lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;&lt;tt&gt;ensureCollectionDroppedNoChangeEvent()&lt;/tt&gt; should be removed from &lt;tt&gt;sharding_ddl_util&lt;/tt&gt;&lt;/li&gt;
	&lt;li&gt;the &lt;a href=&quot;https://github.com/mongodb/mongo/commit/22afc187e2a5ed450cf608458393830eb40b913a#diff-9e131ec0f6ddb8a09f59898d233f07dc242d1c85d0433577ac125845dd695f43L73-L93&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;original version&lt;/a&gt;  of  &lt;tt&gt;ensureCollectionDropped()&lt;/tt&gt; should be reintroduced.&lt;/li&gt;
&lt;/ul&gt;
