            <title>[SERVER-43148] third_party/murmurhash layering violation</title>
                <link>https://jira.mongodb.org/browse/SERVER-43148</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;third_party/murmurhash includes mongo/base and mongo/platform headers unnecessarily. It&apos;s doing this to access ConstDataView to get an unaligned endian swap.&lt;br/&gt;
Unfortunately that brings in a lot of mongo-specifics that can end up bringing in Abseil, and murmurhash isn&apos;t built with Abseil in its #include path.&lt;/p&gt;

&lt;p&gt;So we&apos;re left with unwritten rules about which headers base and ConstDataView can include, or we can fix the layering violation in MurmurHash. I think we should inline the unaligned load and endian-swapping code into murmurhash since that&apos;s a pretty standard operation, and it&apos;s strange for a third_party library to reach out to mongo for support headers anyway.&lt;/p&gt;

&lt;p&gt;I found this by adding stdx/unordered_map to base/init.h and getting a compile failure in murmurhash.&lt;/p&gt;</description>

&lt;p&gt;Dos2unix the source files.&lt;/p&gt;

&lt;p&gt;Fix the unaligned writes.&lt;br/&gt;
(I just reported this upstream) &lt;a href=&quot;https://github.com/aappleby/smhasher/issues/74&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/aappleby/smhasher/issues/74&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Hide undeclared symbols for helper functions in anonymous namespace.&lt;/p&gt;</comment>
