Memory Leak?

[Johannesd3]

When running Librespot (release mode) and skipping through playlists, the used memory increases slowly but steady. It starts with 2-3MB, but after a while I was able to reach 8MB.

It seems to happen in both the dev and the tokio_migration branch.

8MB sounds like approx. two 'normal' length tracks worth of compressed audio data. Could this be the track prefetching working correctly?

[Johannesd3]

I just stopped at 8MB, probably it's possible to reach more. Every time I skip a track, memory usage grows by something between nothing and 0.5MB.

Maybe share your cache settings and which backend also.

[Johannesd3]

I'm using rodio-backend under Windows, no cache enabled.

I tried different configurations out, and it's possible (but I'm not really sure) this is an issue of lewton. With tremor it doesn't exceed 3MB permanently.

Edit: I've reached 3.7MB with tremor, while Iewton seems to stop at this limit too now. It's really hard to reproduce as it doesn't behave deterministic.

Actually I think it's only an issue in dev and I just imagined the same thing happens in tokio_migration when the numbers rose a little. And in dev it happens with both lewton and tremor. So wherever the problem lies, it will probably be fixed by #665.
