Reproduction of a memory leak in dashjs

Primary LanguageJavaScript

Dash Mem Leak

Dash.js keeps a running array of singletons for each dash instance that is created and they do not get cleared out.

Setup

yarn install
node bin/modify-dash.js
yarn start

The modify-dash.js script just adds 2 console.log statements to FactoryMaker.js to make the memory leak obvious.

Run

  • Open http://localhost:3000/
  • Open the dev tools and look at the console log.
  • Press the 'recreate' button

Watch as the count of singletonContexts goes up. It never goes down even though we call reset() on MediaPlayer and the docs say about reset: "Calling this method is all that is necessary to destroy a MediaPlayer instance."
