            <title>[SERVER-50284] See if there is a better alternative to using ValueGuard in SBE tests</title>
                <link>https://jira.mongodb.org/browse/SERVER-50284</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In the course of working on &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-49226&quot; title=&quot;Create unittest fixture for SBE PlanStages&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-49226&quot;&gt;&lt;del&gt;SERVER-49226&lt;/del&gt;&lt;/a&gt; and&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-49225&quot; title=&quot;Create unittest fixture for SBE expression tests&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-49225&quot;&gt;&lt;del&gt;SERVER-49225&lt;/del&gt;&lt;/a&gt; (which introduced some new unittest frameworks for SBE), there were some questions about the best way to manage the lifetime of SBE values and ensure they are freed at the appropriate time when writing unittests (with a particular interest in RAII mechanisms).&lt;/p&gt;

&lt;p&gt;At present, there are a number of places where the ValueGuard class (an RAII mechanism) is being used ensure SBE values are freed at the appropriate time, and SBE value lifetime is managed using manual logic around call sites (for an example of this, see runTest() in &quot;sbe_plan_stage_test.cpp&quot;).&lt;/p&gt;

&lt;p&gt;The goal of this task is to explore whether we can do better.&lt;/p&gt;</description>
