            <title>[SERVER-53676] Race in RecipientForgetMigration_WaitUntilStateDocInitialized</title>
                <link>https://jira.mongodb.org/browse/SERVER-53676</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The test &lt;a href=&quot;https://github.com/mongodb/mongo/blob/4714ce59cc4df667c51f7fce0854a3a776097462/src/mongo/db/repl/tenant_migration_recipient_service_test.cpp#L1309&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;expects an empty &lt;tt&gt;StartApplyingDonorOpTime&lt;/tt&gt;&lt;/a&gt;. But the test doesn&apos;t have a failpoint to block the future chain from getting one and this could race with the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/4714ce59cc4df667c51f7fce0854a3a776097462/src/mongo/db/repl/tenant_migration_recipient_service_test.cpp#L1292-L1293&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this &lt;tt&gt;onReceiveRecipientForgetMigration&lt;/tt&gt;&lt;/a&gt;. If the interruption from the recipientForgetMigration gets in before the future chain calling &lt;a href=&quot;https://github.com/mongodb/mongo/blob/dc3ef13edd2ec8054f97fd160e72dae5edec3061/src/mongo/db/repl/tenant_migration_recipient_service.cpp#L1039&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;_getStartOpTimesFromDonor&lt;/tt&gt;&lt;/a&gt;, the test will pass. However, if the interrupt gets in after that, the state doc could have a &lt;tt&gt;StartApplyingDonorOpTime&lt;/tt&gt; and/or &lt;tt&gt;StartFetchingDonorOpTime&lt;/tt&gt;. Additionally, if the interrupt comes after the cloners have started, the test is also missing &lt;a href=&quot;https://github.com/mongodb/mongo/blob/4714ce59cc4df667c51f7fce0854a3a776097462/src/mongo/db/repl/tenant_migration_recipient_service_test.cpp#L1350-L1351&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mock responses&lt;/a&gt; for the requests coming from the donors.&lt;/p&gt;

&lt;p&gt;The test is only testing that &lt;tt&gt;onReceiveRecipientForgetMigration&lt;/tt&gt; must wait until the state doc is initialized. So we don&apos;t have to have the chain run beyond &lt;tt&gt;fpAfterPersistingTenantMigrationRecipientInstanceStateDoc&lt;/tt&gt;. Therefore, adding a failpoint will fix this.&lt;/p&gt;</description>
