            <title>[SERVER-83095] Allow callstack generator to print in-flight operations</title>
                <link>https://jira.mongodb.org/browse/SERVER-83095</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Logging information helps us to find the root cause queries to confirm and reproduce an underlying bug. In an incident like &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-83091&quot; title=&quot;$or query can trigger an infinite loop during plan enumeration&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-83091&quot;&gt;&lt;del&gt;SERVER-83091&lt;/del&gt;&lt;/a&gt; where there&apos;s a thread causing the mongod to hang indefinitely, we would like to know the shape of the underlying query causing the issue and how to reproduce that consistently within a short time.&lt;/p&gt;

&lt;p&gt;Currently, we have logging for &lt;a href=&quot;https://github.com/10gen/mongo/blob/5d3aed1d73ecb4410e0b04254ec83ea23806e6f4/src/mongo/db/curop.cpp#L603&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;slow queries&lt;/a&gt; and &lt;a href=&quot;https://github.com/10gen/mongo/blob/5d3aed1d73ecb4410e0b04254ec83ea23806e6f4/src/mongo/util/stacktrace_threads.cpp#L688&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;printAllThreadStacks&lt;/a&gt; for this purpose. However, the former one only prints upon the completion of a query, while the latter prints the stack trace with limited information about the query shapes.&lt;/p&gt;

&lt;p&gt;This ticket proposes to log the in-progress queries whenever printAllThreadStacks is called such that we are able to see the underlying queries contributing the those stack traces.&lt;/p&gt;</description>
