Blacklist doesn't work for one program

[aacater]

If I have blacklisted a program, the extension ignores the blacklist when I open the blacklisted program.

However, if the extension already sees the program and has controls for it and then I blacklist the program, the extension properly ignores the program. But then if I restart the program, the extension ignores the blacklist again and shows controls for the blacklisted program.

The program I am trying to block is freetube, installed as a flatpak (link). The extension properly blocks Spotify however, also installed as a flatpak. So maybe this is a problem with freetube and not the extension?

Info:

• Extension Version 34
• Fedora Silverblue 39.20240117.0
• Gnome 45.3

P.S. I really like the rewrite, good work!

[sakithb]

I just installed Freetube and tried blacklisting it, and it worked as expected, the extension does not show up when opening Freetube if its is blacklisted. The last update was a total rewrite of the extension so it was rather a huge update, so can you try removing all blacklisted players and adding them one by one?

[aacater]

The only app I want to block is freetube so my blacklist is empty except for it. I have removed and re-added it multiple times.

Since its just me, I'll continue to test. Like seeing if it happens on my laptop or if its just my desktop for some reason.

[aacater]

Same behavior on my laptop. Also running Fedora Silverblue.

Also tested blocking Firefox, it works as expected. So it seems I am only having trouble with Freetube for some reason.

[sakithb]

Does the extension show the correct freetube icon?

[aacater]

No, it does not. However the icon is show properly in the blacklist settings.

[aacater]

• I have discovered, for some reason, sometimes it works. I haven't tracked down the exact steps to reproduce it yet. But sometimes I will be using freetube and then notice its blacklisted properly. But if I restart freetube then it will be back to not blacklisted.
• The icon in the extension will show up sometimes. I think it has something to do with switching between apps in the extension. Once I switch back to freetube, the icon is there. If I restart freetube the icon is missing again.

[sakithb]

I noticed that Freetube exposes two MPRIS services (this extensions uses these services to identify media players), one was called Freetube and the other was called chromium (this makes sense assuming Freetube uses Electron), maybe this plays a part in the issue, I am not sure, but I will look into it. The odd thing is I always get the correct Freetube icon in the extension. What is your freetube version?

[aacater]

I am currently using v0.19.1 Beta.

[sakithb]

Im on the same version. It's really weird that it works for me, but not for you. Is you laptop on Fedora Silverblue as well?

[aacater]

Yes, laptop is running Fedora Silverblue as well.

Random information/thoughts that may or may not be helpful:

• I noticed freetube changes the window's name based on the video playing. Could that be interfering with the blacklist?
• you can open multiple freetube windows to play multiple videos at once, but the extension only shows one freetube. The extension will show controls for the last video that was started/stopped.
  • next time I notice the blacklist working I am going to test if opening a second window breaks the blacklist.
  • Two windows does not break the blacklist.
• this is happening on both X11 and wayland. I run X11 on my desktop and wayland on my laptop.

---

I am still trying to track down the exact circumstances of when blacklist works and when it doesn't. Currently it seems to work after a certain amount of time. Or something I do infrequently makes it work.

It definitely doesn't work right after I reboot and/or login. Which is weird to me, I would expect it to work then if at all...

Is there any debug logs I can provide or something like that?

[sakithb]

Can you post the output of this command? gdbus call --session --dest org.freedesktop.DBus --object-path /org/freedesktop/DBus --method org.freedesktop.DBus.ListNames | grep -Poi "'org.mpris.Mediaplayer2\..+?'" | xargs -I{} gdbus introspect --session --dest {} --object-path /org/mpris/MediaPlayer2

This command will list all the active media players and fetch their information via gdbus. Make sure the freetube is open and playing a video before running this command.

These commands were run when I was playing a video in freetube and the extension's blacklist was not working properly.

[sakithb]

That's very weird, I guess the empty node is Freetube.

[sakithb]

Are you able to control freetube properly through the extension?

[aacater]

Yes, the extension is able to control freetube properly.

Since freetube's node is empty, does that mean this is a freetube bug? Or maybe even gbus?

[sakithb]

I think this is a chromium bug. I've noticed this issue in some chrome versions. Not sure if it is fixed in the latest.

[sakithb]

@aacater Is this fixed now?

[aacater]

I think so. At least I haven't noticed it happening but I am also using freetube less.

Thanks!
