            <title>[SERVER-62267] Ensure memory associated with parsed DDL coordinator document is kept alive</title>
                <link>https://jira.mongodb.org/browse/SERVER-62267</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;I realized that we actually have the same problem for all the classes that extend the &lt;tt&gt;ShardingDDLCoordinator&lt;/tt&gt;.&lt;br/&gt;
 Many of the classes that extend the &lt;tt&gt;ShardingDDLCoordinator&lt;/tt&gt;&#160; parse their &lt;a href=&quot;https://github.com/mongodb/mongo/blob/9766c982d67c2a8584e329f024d702d8e2c8138e/src/mongo/db/s/create_collection_coordinator.cpp#L385-L386&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;coordinator document at construction time&lt;/a&gt;. On the other hand our parsing implementation doesn&apos;t take ownership of nested &lt;tt&gt;BSONObj&lt;/tt&gt; if they are not defined as &lt;tt&gt;object_owned&lt;/tt&gt;, so if the coordinator document contains any nested object that is not owned, the parsed coordinator doc stored as a member of the coordinator instance will point to invalid memory.&lt;br/&gt;
 I find this very error prone, so I was thinking to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/9766c982d67c2a8584e329f024d702d8e2c8138e/src/mongo/db/s/sharding_ddl_coordinator.cpp#L65-L70&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;store a serialized copy of the raw coordinator document in the ShardingDDLCoordinator parent class&lt;/a&gt; so that we can ensure that the memory associated with all the fields in the parsed coordinator document will remain alive until the coordinator instance is destructed.&lt;/p&gt;</description>
