            <title>[SERVER-43731] Unify oplog visibility timestamp updates</title>
                <link>https://jira.mongodb.org/browse/SERVER-43731</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Now, both &lt;a href=&quot;https://github.com/mongodb/mongo/blob/12011588f517f910ea5b6a34591755b3ca04223d/src/mongo/db/repl/initial_syncer.cpp#L1248-L1257&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;initial syncer&lt;/a&gt; and &lt;a href=&quot;https://github.com/mongodb/mongo/blob/12011588f517f910ea5b6a34591755b3ca04223d/src/mongo/db/repl/oplog_applier_impl.cpp#L279-L282&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;oplog applier&lt;/a&gt; rely on calling &lt;tt&gt;oplogDiskLocRegister&lt;/tt&gt; to update oplog visibility ts after calling &lt;tt&gt;multiApply&lt;/tt&gt;. After &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-42925&quot; title=&quot;idempotency tests have oplog visiblity issues&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-42925&quot;&gt;&lt;del&gt;SERVER-42925&lt;/del&gt;&lt;/a&gt;, idempotency tests also rely on &lt;tt&gt;oplogDiskLocRegister&lt;/tt&gt; to mimic the server behavior. This makes it very easy for one to forget calling &lt;tt&gt;oplogDiskLocRegister&lt;/tt&gt;. It seems that it is always the case that we want to update oplog visibility after oplog application. So it is probably a good idea to unify/merge the oplog visibility logic into &lt;tt&gt;multiApply&lt;/tt&gt;. &lt;/p&gt;</description>

I don&apos;t want to increase the scope of that project too much, but this at least seems related.&lt;/p&gt;</comment>
