            <title>[SERVER-47312] Run hang_analyzer.py via assert.soon() without calling gcore on ASan builders</title>
                <link>https://jira.mongodb.org/browse/SERVER-47312</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The changes from &lt;a href=&quot;https://github.com/mongodb/mongo/commit/e89c041616cbaea0648bb60ce32ddab1f33d3e97&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;e89c041&lt;/a&gt; as part of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-45884&quot; title=&quot;Don&amp;#39;t run the hang analyzer on ASAN builds&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-45884&quot;&gt;&lt;del&gt;SERVER-45884&lt;/del&gt;&lt;/a&gt; disabled running the hang analyzer on ASan build variant (i.e. builders using &lt;tt&gt;--sanitize=address&lt;/tt&gt;) via &lt;tt&gt;assert.soon()&lt;/tt&gt; due to &lt;tt&gt;gcore&lt;/tt&gt; not respecting the &lt;tt&gt;madvise()&lt;/tt&gt; settings on the 20TB of shadow memory. This had come up previously in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-29886&quot; title=&quot;Hang analyzer shouldn&amp;#39;t produce core dumps on ASan builders&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-29886&quot;&gt;&lt;del&gt;SERVER-29886&lt;/del&gt;&lt;/a&gt; for the &quot;timeout&quot; phase in the &lt;tt&gt;etc/evergreen.yml&lt;/tt&gt; project configuration and was resolved by running hang_analyzer.py without the &lt;tt&gt;-c&lt;/tt&gt; option in order to avoid producing core dumps.&lt;/p&gt;

&lt;p&gt;We could similarly have the mongo shell omit the &lt;tt&gt;&lt;del&gt;c&lt;/tt&gt; option when running hang_analyzer.py. On a related note - the mongo shell offers an &lt;tt&gt;_isAddressSanitizerActive()&lt;/tt&gt; function which returns true if it was compiled with &lt;tt&gt;&lt;/del&gt;-sanitize=address&lt;/tt&gt; (we generally assume the server binaries have the same build flags), so we should consider removing &lt;tt&gt;TestData.isAsanBuild&lt;/tt&gt; to avoid there being two ways of expressing the same thing.&lt;/p&gt;

&lt;p&gt;Add a test to check that the hang_analyzer still runs on ASan without dumping core.&lt;/p&gt;</description>
