            <title>[DRIVERS-2529] Add tests for endSessions cleanup behavior</title>
                <link>https://jira.mongodb.org/browse/DRIVERS-2529</link>
                <project id="10980" key="DRIVERS">Drivers</project>
                    <description>&lt;div class=&quot;panel&quot; style=&quot;background-color: #fafbfc;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #fafbfc;&quot;&gt;
&lt;h3&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;&lt;b&gt;Summary&lt;/b&gt;&lt;/h3&gt;

&lt;p&gt;The sessions specification requires that drivers execute an endSessions command on client close, but there aren&apos;t any tests for this behavior. The Rust driver accidentally omitted this feature and it went unnoticed for a while as a result (&lt;a href=&quot;https://jira.mongodb.org/browse/RUST-1437&quot; title=&quot;Driver does not send endSessions on client shutdown&quot; class=&quot;issue-link&quot; data-issue-key=&quot;RUST-1437&quot;&gt;RUST-1437&lt;/a&gt;).&lt;/p&gt;

&lt;p&gt;Now that Client.close is supported in the Unified Test Format, automated tests could be used for this purpose.&lt;/p&gt;

&lt;h3&gt;&lt;a name=&quot;Motivation&quot;&gt;&lt;/a&gt;&lt;b&gt;Motivation&lt;/b&gt;&lt;/h3&gt;
&lt;h4&gt;&lt;a name=&quot;Whoistheaffectedenduser%3F&quot;&gt;&lt;/a&gt;Who is the affected end user?&lt;/h4&gt;

&lt;p&gt;&lt;em&gt;Driver authors, users if the feature isn&apos;t implemented properly.&lt;/em&gt;&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Howdoesthisaffecttheenduser%3F&quot;&gt;&lt;/a&gt;How does this affect the end user?&lt;/h4&gt;

&lt;p&gt;&lt;em&gt;The endSessions command might not be run, or it might be run in unstandardized ways across drivers.&lt;/em&gt;&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Howlikelyisitthatthisproblemorusecasewilloccur%3F&quot;&gt;&lt;/a&gt;How likely is it that this problem or use case will occur?&lt;/h4&gt;

&lt;p&gt;&lt;em&gt;This codepath is executed every time a client shuts down, so it&apos;s on the main path.&lt;/em&gt;&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Iftheproblemdoesoccur%2Cwhataretheconsequencesandhowseverearethey%3F&quot;&gt;&lt;/a&gt;If the problem does occur, what are the consequences and how severe are they?&lt;/h4&gt;

&lt;p&gt;&lt;em&gt;Long running operations may not be cancelled in some drivers when the client is closed, or the behavior for cancelling them may vary from driver to driver.&lt;/em&gt;&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Isthisissueurgent%3F&quot;&gt;&lt;/a&gt;Is this issue urgent?&lt;/h4&gt;

&lt;p&gt;&lt;em&gt;No&lt;/em&gt;&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Isthisticketrequiredbyadownstreamteam%3F&quot;&gt;&lt;/a&gt;Is this ticket required by a downstream team?&lt;/h4&gt;

&lt;p&gt;&lt;em&gt;Shell maybe? (see &lt;a href=&quot;https://jira.mongodb.org/browse/NODE-3263&quot; title=&quot;Calling close() does not terminate all connections&quot; class=&quot;issue-link&quot; data-issue-key=&quot;NODE-3263&quot;&gt;NODE-3263&lt;/a&gt;)&lt;/em&gt;&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Isthisticketonlyfortests%3F&quot;&gt;&lt;/a&gt;Is this ticket only for tests?&lt;/h4&gt;

&lt;p&gt;&lt;em&gt;Yes&lt;/em&gt;&lt;/p&gt;
&lt;/div&gt;&lt;/div&gt;</description>
