            <title>[SERVER-58222] Investigate op_observer_sharding_impl.cpp lock acquisition</title>
                <link>https://jira.mongodb.org/browse/SERVER-58222</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;A new invariant was added where operations that are holding open an oplog hole cannot try to acquire subsequent locks.&lt;/p&gt;

&lt;p&gt;To temporarily circumvent this check, a new RAII-style class called IgnoreLockConstraintsOnTimestampedTxn&#160;was added to opt-out of the invariant.&lt;/p&gt;

&lt;p&gt;There&apos;s a TODO in the codebase for this ticket. See&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-48129&quot; title=&quot;Invariant that operations which are holding open an oplog hole cannot block when acquiring locks&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-48129&quot;&gt;&lt;del&gt;SERVER-48129&lt;/del&gt;&lt;/a&gt;&#160;for additional information.&lt;/p&gt;

&lt;p&gt;The goal of this ticket should be to determine whether acquiring the lock can actually block in practice (perhaps another thread acquires a stronger lock).&lt;/p&gt;</description>
