            <title>[SERVER-32532] Two-phase dropDatabase may not replicate all collection drops before the database drop.</title>
                <link>https://jira.mongodb.org/browse/SERVER-32532</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The first phase of &lt;tt&gt;dropDatabase&lt;/tt&gt; (for replicate sets) in 3.6 is to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/60799be6648b497741d029c7e641402b2a8035eb/src/mongo/db/catalog/drop_database.cpp#L138-L155&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;individually drop each collection&lt;/a&gt; (drop in this first phase is a misnomer for rename). When those &quot;drops&quot; are &lt;a href=&quot;https://github.com/mongodb/mongo/blob/60799be6648b497741d029c7e641402b2a8035eb/src/mongo/db/catalog/drop_database.cpp#L197-L198&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;majority confirmed&lt;/a&gt;, the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/60799be6648b497741d029c7e641402b2a8035eb/src/mongo/db/catalog/drop_database.cpp#L252&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;primary replicates&lt;/a&gt; a &lt;tt&gt;dropDatabase&lt;/tt&gt; oplog entry.&lt;/p&gt;

&lt;p&gt;However the loop uses an iterator over the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/60799be6648b497741d029c7e641402b2a8035eb/src/mongo/db/catalog/database_impl.h#L299&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;_collections map&lt;/a&gt; and &lt;tt&gt;db-&amp;gt;dropCollectionEvenIfSystem&lt;/tt&gt; will perform a rename. This rename &lt;a href=&quot;https://github.com/mongodb/mongo/blob/60799be6648b497741d029c7e641402b2a8035eb/src/mongo/db/catalog/database_impl.cpp#L643&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;erases the entry&lt;/a&gt; followed by &lt;a href=&quot;https://github.com/mongodb/mongo/blob/60799be6648b497741d029c7e641402b2a8035eb/src/mongo/db/catalog/database_impl.cpp#L704&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;adding it back under a different name&lt;/a&gt;. The expectation of the for-each collection loop is that all collections will be observed. The erase/add of the underlying map breaks that requirement.&lt;/p&gt;

&lt;p&gt;This can result in some collections not being dropped on the primary nor the secondary in the first part of dropping a database. I do believe the second phase of dropping a database that&apos;s associated with the &lt;tt&gt;dropDatabase&lt;/tt&gt; oplog entry will be renamed and/or dropped on both the primary and secondary.&lt;/p&gt;

&lt;p&gt;One possible fix is to copy the values from the map to iterate over instead.&lt;/p&gt;</description>
