| + <h1>Test Premature GC on ScriptProcessorNode</h1>
|
| +
|
| + <p><strong>NOTE: This test requires HTTP server and getUserMedia (i.e. live
|
| + audio input).</strong></p>
|
| +
|
| + <p>ScriptProcessorNode's the node reference should not get garbage collected
|
| + even when it is out of scope as long as <code>onaudioprocess</code>
|
| + handler is active.</p>
|
| +
|
| + <p>This test must be performed manually, because 1) ScriptProcessorNode is
|
| + not compatible with OfflineAudioContext, thus 2)
|
| + <code>onaudioprocess</code> is being fired asynchronously.</p>
|
| +
|
| + <p>As soon as this page loads, you should see the counter number increases
|
| + without stopping. Without the fix, the counter does not increase at all.
|
| + This test can be flaky, so it should be attempted repeatedly to see fail.
