            <title>[SERVER-50852] BF Day - Hang analyzer&apos;s &quot;interesting processes&quot; pattern for C++ unit tests doesn&apos;t match db_unittests</title>
                <link>https://jira.mongodb.org/browse/SERVER-50852</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://evergreen.mongodb.com/task/mongodb_mongo_master_ubuntu1804_debug_aubsan_lite_unittests_f825465df95a1e663f65c149b2fe6412778372eb_20_09_02_03_18_47/0&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://evergreen.mongodb.com/task/mongodb_mongo_master_ubuntu1804_debug_aubsan_lite_unittests_f825465df95a1e663f65c149b2fe6412778372eb_20_09_02_03_18_47/0&lt;/a&gt; was a case where the hang analyzer didn&apos;t attach to the db_unittests process. I believe this is due to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/74c76f296cfe3e6c2943d248bec49c84c0ea5b96/buildscripts/resmokelib/hang_analyzer/hang_analyzer.py#L44&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&quot;_test&quot; being expected in the name for C++ unit test binaries&lt;/a&gt;. db_unittests doesn&apos;t follow that pattern.&lt;/p&gt;

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-51692&quot; title=&quot;Lint C++ unit test binary name to end with _test&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-51692&quot;&gt;&lt;del&gt;SERVER-51692&lt;/del&gt;&lt;/a&gt; Add linting check for unittest names&lt;/p&gt;

&lt;p&gt;We discovered in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-50852&quot; title=&quot;BF Day - Hang analyzer&amp;#39;s &amp;quot;interesting processes&amp;quot; pattern for C++ unit tests doesn&amp;#39;t match db_unittests&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-50852&quot;&gt;&lt;del&gt;SERVER-50852&lt;/del&gt;&lt;/a&gt; that when unit test binary names do not&lt;br/&gt;
end with &quot;_test&quot; it can cause problems with the hang check analyzer. To&lt;br/&gt;
prevent such occurrences in the future, all CppUnitTest targets must&lt;br/&gt;
will be checked to ensure they are named correctly.&lt;br/&gt;
