Does Submariner detect and attempt to squash duplicate tracks between servers?

[simensen]

Hello,

New to Submariner, here! I've finally set up my Navidrome servers the way I want and finding some weirdness with some of the tracks when navigating with Submariner.

My setup:

# Filesystem
/srv/Music
  DJ/       // tracks that are specifically intended for djing 
  Mixes/    // my own DJ mixes and downloads/recordings from other DJs
  Music/    // commercial music, albums, etc.

# Navidrome.lan – instance indexes all music under /srv/Music
/srv/Music:/music

# Navidrome-DJ.lan – instance indexes just the DJ library
/srv/Music/DJ:/music

# Navidrome-Mixes.lan – instance indexes just the Mixes library
/srv/Music/Mixes:/music

# Navidrome-Music.lan – instance indexes just the Music library
/srv/Music/Music:/music

When I visit navidrome.lan, navidrome-dj.lan, navidrome-mixes, or navidrome-music.lan via browser, I see what I expect to see. The big navidrome.lan instance shows me everything across all three directories. When I visit any of the other three, I only see songs for their specific directories.

However, when I add all four instances as separate servers to Submariner, things are... a bit weird. It looks like Submariner is looking at the four libraries and only including a specific track once. So, since I loaded up navidrome-dj.lan first, the albums show up under navidrome.lan (including some album art!), but the actual list of tracks for those albums are empty and have no tracks at all.

To experiment, I removed navidrome-dj.lan, navidrome-mixes, or navidrome-music.lan as remote servers and left navidrome.lan. Once I did that, all the missing tracks appeared under the albums as expected.

I'd love to have the option to keep all four instances running. In general, the main instance (navidrome.lan) is probably what I'll use, but I'd love to be able to select one of the other two instances as needed if I want to filter based on supertype.

Is this a bug or working as intended?

The artists/albums/tracks for each should be separate for each server. I wouldn't be surprised if there might be an issue with missing server predicates when doing queries though.

FWIW Submariner also doesn't support the "music folder" concept in the API, but I don't think Navidrome supports that.

I did look at the track fetch code in c31087a. I wonder if that might help.

What is the best way for me to try c31087a? I've never built a project like this by hand, so that could be fun. :)

You can try the build artifacts from CI runs, i.e. here: https://github.com/NattyNarwhal/Submariner/actions/runs/5159606089 - There aren't signed, however.

If you want to try building it yourself, install Xcode and try the instructions here: https://github.com/NattyNarwhal/Submariner#building
