Does this mean we should bump the required modify version? Thanks for pushing this across the finish line btw!

[jjok]

Oh, I hadn't thought of that. It's not actually a requirement. It's just that this new method won't mean anything with an older version.
I guess it's required of you want this extension to work well, but we'd have to wait for a Mopidy release before merging this.
What do you think?

[kingosticks]

FYI I'm just adding the uri parameter to should_download, might as well get that in there now.

[jjok]

Ok. Is that just so it has the same interface as is_live() or can you see a situation where the method might need to do some logic based on the uri?

[kingosticks]

Mostly the second. There might be a day when we tell this workaround isn't required for certain tracks, or where we want to avoid doing it for really long tracks. I see no reason not to pass this extra information in and make the API more flexible, the backend does not have to use it.

[jjok]

I'll add that param here too then, yeah?

[kingosticks]

I'll add that param here too then, yeah?

Sorry, yes. We've merged mopidy/mopidy#1907 and added the new API to the v3.1 milestone, so that's the new minimum Mopidy version you must target if using should_download. There's only currently one other thing to finish off in v3.1 before releasing so hopefully it won't be long.

Closing because Google Play Music has been shut down, and this project is being discontinued.
