            <title>[SERVER-69901] Fix racy initialization of `CommandInvocationHooks`</title>
                <link>https://jira.mongodb.org/browse/SERVER-69901</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;tt&gt;CommandInvocationHooks&lt;/tt&gt; are defined as a decoration on &lt;tt&gt;ServiceContext&lt;/tt&gt; and define server-specific behavior that should run before and after running commands.&lt;/p&gt;

&lt;p&gt;Accesses to this decoration are not synchronized, so initializing it after its first use may case data races. For example, &lt;tt&gt;mongod&lt;/tt&gt; initializes these hooks from &lt;a href=&quot;https://github.com/mongodb/mongo/blob/7868a6387999a37bff0690fcbd7e764428d61880/src/mongo/db/mongod_main.cpp#L676&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;, however, other threads may access the hooks as part of running commands before it is initialized (e.g., &lt;tt&gt;ReadThroughCache&lt;/tt&gt;.&lt;/p&gt;

&lt;p&gt;This ticket should address this data race, either by proposing an alternative initialization order or adopting synchronization primitives. &lt;/p&gt;</description>
