            <title>[SERVER-40159] Add retry logic for name resolution failure in isSelf</title>
                <link>https://jira.mongodb.org/browse/SERVER-40159</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently, &lt;a href=&quot;https://github.com/mongodb/mongo/blob/4cfb6cd851ef56c8e33bb0587567e9b91153c0de/src/mongo/db/repl/isself.cpp#L175&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;isSelf &lt;/a&gt; does not contain any retry logic when attempting name resolution. This causes build failures for tests that experience transient network failures.&lt;/p&gt;

&lt;p&gt;We would like to add retry loops to &lt;tt&gt;getAddrInfo&lt;/tt&gt; to reduce these build failures, but it is important that we don&apos;t retry forever in case the network failure is indeed not transient (eg. dns misconfiguration).&lt;/p&gt;

&lt;p&gt;This requires threading the opCtx to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/2c246e5860c598759622cebadd863b53cbd668a0/src/mongo/db/repl/isself.cpp#L107&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;getAddrInfo &lt;/a&gt; and may require some refactoring of unit tests to implement cleanly.&lt;/p&gt;</description>

                            <comment id="2219423" author="jason.carey" created="Fri, 19 Apr 2019 17:52:20 +0000"  >&lt;p&gt;We may still want to do this ticket, but without constraints on what we want to do with transient dns failures (should we retry?  at what level?  for how long?), I think there&apos;s no obvious way forward.&lt;/p&gt;

&lt;p&gt;For cleaning up bfs, I&apos;d prefer we do BUILD-8351.  If we want to test transient dns failures, it would be more useful to do so with a fail point (which we could use to better check edge cases)&lt;/p&gt;</comment>
