In <a href="https://sergiocomeron.com/blog/en/posts/deuda-tecnica-mod-jitsi/">part 1</a> I broke apart two &ldquo;god files&rdquo;; in <a href="https://sergiocomeron.com/blog/en/posts/deuda-tecnica-mod-jitsi-2/">part 2</a> I took apart the 924-line video-call function. One monster remained: <strong><code>view.php</code></strong>, the page the student or teacher sees when entering the activity. 971 lines mixing everything.</p> <p>I refactored it with the usual recipe. But this time the refactor itself is the least of it —it&rsquo;s the same pattern as the previous parts—. What was interesting was <strong>what showed up when I lifted the rugs</strong>: a query scanning the whole site&rsquo;s log table, a cache hiding it, an N+1, a bug that let you record and stream at once, and a couple of &ldquo;time capsules&rdquo; buried in the code.</p>
