Memory Leak (?) on Ubuntu Linux

[rodrigomessiasbarros]

Hello,

I'm using MusicPod on Ubuntu 24.04.01 LTS and when I add some podcasts to the playlist (I thought it was a feature to favorite the podcast and not include ALL the episodes of a podcast in the playlist, anyway) when I go to the Playlist and scroll with the mouse, the application reaches 23GB of RAM consumption. I believe there is some memory leak happening here.

How to reproduce the problem.

Open the application, add 2 or 3 podcasts to the playlist and go to the playlist and scroll to the end. Monitor the memory consumption in a resource manager.

Here when I start the application:

Here when I reproduce the problem:

History of memory consumption: (up and down)

Consumption Up

Consumption Down

(when I quit the app)

About my system:

MusicPod version: 0+git.07e2a34

hi thanks for the very detailed report!
This button should not be there for podcasts, for podcasts there is the 🔔 icon to add it to the sidebar and update it : D

I can definitely help you, what would these steps be?

For instance which podcasts did you add to what playlist?

(And for now if you want to subscribe to a podcast which adds it to your library, just press the bell 🔔 icon. I'll make the iconography more clear)

[Feichtmeier]

And what icon did you press

[rodrigomessiasbarros]

OK, I add this podcast:

• Project N (Brazilian Podcast about Nintendo),
• Ultra N Podcast (Nintendo too),
• Conexao Nintendo (Nintendo too)
• N-Blast-Cast - Podcast Nintendo Brasil (off course Nintendo)
• Nintendo POWdcast (Nintendo too, I known I have a problem).

Inside a PodCast Banner, I click on tree dot menu [More Options], then "Add to Playlist" button:

I hope this make help find this bug.

No you dont have a problem, its nice to be happy about a hobby ^^

so I couldntreproduce a real leak, but indeed the memory consumtion increases for a while, then shrinks again though. I think what happens is the podcasts you have use very high quality images and since I did not design playlist pages to include podcasts (yet) those images are fully loaded, evenif resized, though cached. Since I didnt thought this through (because I thought the bell would be clear but clearly it isnt and the icon was a bad idea) I didnt look into the large images for those tiles yet. I disabled this for now, sorry! This is what you should do instead:

• press on the bell to sub to a podcast (in the snap edge channel a fix is soon in which changes this to a plus icon)
• find your subbed podcasts in the sidebar and on the podcasts library page

the playlist feature is currently only designed around local audio files, for podcasts there is a special page which looks like this:

I keep this issue here opened to remind me to properly feature this for people who might want to create playlists with podcasts!
