            <title>[SERVER-52662] Introduce type-associated mutexes</title>
                <link>https://jira.mongodb.org/browse/SERVER-52662</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When we originally wrote MONGO_MAKE_LATCH &lt;a href=&quot;https://github.com/mongodb/mongo/blob/6508f5d6ad5d514f433b660f0da7f513625973be/src/mongo/platform/mutex.h#L373-L378&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;, we considered various macros to accept information from wrapping classes. We eventually decided against this tact in favor of simplicity. We now think it might be worthwhile to absorb this information, especially when the class that needs a mutex is templated. This will require a new macro ala &lt;tt&gt;MONGO_MAKE_LATCH_FOR_TYPE&lt;/tt&gt; that passes its captured type as a template to the registry macro in some form. That macro will need to be able to invoke a unique template instantiation to achieve registry, which means an extra type in its template.&lt;/p&gt;</description>

                            <comment id="3479735" author="ben.caimano" created="Fri, 6 Nov 2020 16:29:36 +0000"  >&lt;p&gt;I have a few different ideas for how we can capture the additional type information:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;&lt;tt&gt;getOrMakeLatchData()&lt;/tt&gt; could take a second template parameter and a fourth argument that uses that parameter. For existing latches, this would default to &lt;tt&gt;void&lt;/tt&gt; and be a constexpr if special case.&lt;/li&gt;
	&lt;li&gt;We could use a new function &lt;tt&gt;getOrMakeLatchDataForType()&lt;/tt&gt; that takes the &lt;tt&gt;typeid&amp;lt;T&amp;gt;&lt;/tt&gt; as the parameter instead of the tag class.&lt;/li&gt;
	&lt;li&gt;We could introduce a CRTP base class &lt;tt&gt;LatchHolder&amp;lt;DerivedT&amp;gt;&lt;/tt&gt; that instantiates and registers the &lt;tt&gt;Latch&lt;/tt&gt; and constructs with a &lt;tt&gt;SourceLocation&lt;/tt&gt;.&lt;/li&gt;
&lt;/ul&gt;
