869812 - Podcasts encounters error on download to indexeddb

Status: RESOLVED FIXED

(Marketplace Graveyard :: Reference Apps, defect)

Description

[tofumatt [:tofumatt]]

It seems like saving the request.response of certain very large podcasts causes IndexedDB and the app to crash on a Unagi device. This cannot be replicated on the simulator, but happens with relative ease on device.

It seems I'll need to write the file with a buffer or use the Devicestorage/File API to save these large files.

This is the only current blocker to the app being on the marketplace.

Moving this to the next sprint, as it's turned out to be a bit of a beast. I'll need to save the download in chunks in order to free up memory and not hit out-of-memory errors.

It seems there is NO way to get this functionality on 1.0.x, but I'm hoping a minimum version option in Marketplace (bug 879641) will allow me to submit this app to the Marketplace.

Save episodes in chunks (Fix bug 869812)

This saves podcast episodes in a crude-yet-simply-effective way to IndexedDB.
Retrieving the stored arrayBuffers from IndexedDB and assembling a new `Blob`
object from them SEEMS not to OOM the app on phones, though it still spikes
memory usage.

Also fixes some type hacks used previously.
