            <title>[SERVER-64986]  Add concurrency workloads that test internal transactions using test command</title>
                <link>https://jira.mongodb.org/browse/SERVER-64986</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We currently have test coverage for internal transactions in the following concurrency workloads:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;random_moveChunk_update_shard_key.js
	&lt;ul&gt;
		&lt;li&gt;This performs WouldChangeOwningShard update and findAndModify while migrating chunks. It uses both retryable writes and multi-document transactions.&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;random_moveChunk_update_shard_key_kill_sessions.js
	&lt;ul&gt;
		&lt;li&gt;Same as random_moveChunk_update_shard_key.js but additionally kills sessions.&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;random_internal_transactions_setFCV_operations.js
	&lt;ul&gt;
		&lt;li&gt;This performs WouldChangeOwningShard update and findAndModify while changing the FCV.&#160;&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;The workloads provide test coverage for:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Running an internal transaction on behalf of a client command running as a retryable write or multi-document transaction (has an lsid and a txnNumber).&lt;/li&gt;
	&lt;li&gt;Retrying and reconstructing responses from WouldChangeOwningShard noop entries.&lt;/li&gt;
	&lt;li&gt;Killing&#160;internal sessions for retryable write.&lt;/li&gt;
	&lt;li&gt;Downgrading FCV when there are existing and active internal transactions for retryable writes.&lt;/li&gt;
	&lt;li&gt;Migrating chunks when there are&#160;existing and active internal transactions for retryable writes.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;We still don&apos;t have concurrency test coverage for the following:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Running an internal transaction on behalf of a client command not running in a session (no lsid) or not running as a retryable write or multi-document transaction (no txnNumber)&lt;/li&gt;
	&lt;li&gt;Retrying and reconstructing responses from retryable insert, update, delete and findAndModify (with a pre or post image) entries.&lt;/li&gt;
	&lt;li&gt;Killing&#160;internal sessions for non-retryable writes.&lt;/li&gt;
	&lt;li&gt;Reaping internal sessions for retryable writes and for non-retryable writes.&#160;&lt;/li&gt;
	&lt;li&gt;Downgrading FCV when there are existing or active internal transactions for non-retryable writes.&lt;/li&gt;
	&lt;li&gt;Migrating chunks when there are existing and active internal transactions for non-retryable writes.&lt;/li&gt;
	&lt;li&gt;Resharding the collection when there are existing and active internal transactions for retryable writes and for non-retryable writes.&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;Note that we have test coverage for (2), (4), (6) and (7) in jstests/sharding/internal_txns.&lt;/p&gt;</description>
