pulseaudio-plugin failing after downgrade

Hi,

on Gentoo I was using the testing branch 4.17* because I like to have the latest features and Xfce releases are slow anyway. Then I ran into the xfconf bug that deleted all my panels. Eventhough this bug is fixed in the meanwhile I learned that running this kind of development versions might break productive systems and I downgraded the testing branch of Xfce4 4.17* do 4.16*.

Almost everything is working, but xfce4-pulseaudio-plugin is failing to start: It always "unexpectedly left the panel, do you want to restart it" ? Afaik this plugin doesn't have any custom configuration, I can't find a file "*pulse*" in the xfce4 config tree. What can I do? Right now the plugin is removed from the panel and I can't find any reference to it:

grep -R pulse ~/.config/xfce4*

I was using PulseAudio and recently migrated to PipeWire. xfce4-pulseaudio-plugin was always working while I had the testing Xfce 4.17* branch and now fails after downgrading to 4.16*.

Re: pulseaudio-plugin failing after downgrade

It looks like a mixture of installations in /usr/local and /usr. Basically, delete everything you have in /usr/local and install in /usr instead, and it should work.

I think that's also where your problem in https://gitlab.xfce.org/xfce/xfce4-pane … note_59863 comes from.

Re: pulseaudio-plugin failing after downgrade

I don't think so. /usr/local/ doesn't have anything Xfce related here. /usr/local/bin are just my personal scripts, /usr/local/share/applications just has some local shortcuts...
If there is a version mismatch in /usr, then Gentoo's portage would have broken something which I doubt. As for the gitlab issue, portage only has one version of each installed at time, there are no conflicting versions. Currently there are no dependency conflicts. This is the installed set of Xfce:

Ok, and could you give also

ls -l /usr/lib64/xfce4/panel/plugins

Re: pulseaudio-plugin failing after downgrade

Okay so you're right, it doesn't seem to be a mix of installs

Now, could you give:
* a screenshot of the error dialog when you try to add the plugin
* the console output of the panel at that time (do xfce4-panel -q && xfce4-panel beforehand if needed)

Re: pulseaudio-plugin failing after downgrade

Right, that debug output is what I was looking for:

(process:7388): GLib-WARNING **: 12:02:16.268: (../glib-2.74.1/glib/gerror.c:763):g_error_new_valist: runtime check failed: (domain != 0)

Especially

undefined symbol: xfce_panel_plugin_popup_menu

Well this might be Gentoo related, something should have been rebuilt after changed dependencies. Usually this can be done via revdep-rebuild to rebuild reverse dependencies if required, but wasn't found... Downgrades are not that well tested in the distribution.

$ ldd /usr/lib64/xfce4/panel/plugins/libpulseaudio-plugin.so

looks good, so no broken dependency after the downgrade.
Anyway, I just rebuilt the xfce-extra/xfce4-pulseaudio-plugin and now it's working. Sorry for the confusion. Most binary distros won't have these issues...

Re: pulseaudio-plugin failing after downgrade

Yes the plugin was built with libxfce4panel >= 4.17.2 from which xfce_panel_plugin_popup_menu() was added, and therefore must be rebuilt when downgrading.

I would have liked to know if, starting from a working 4.16.x install (so in particular with a valid ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml file), upgrading to the current 4.17.x branch of Gentoo works (i.e. going directly from Xfconf 4.16.0 to 4.17.1).

But I don't want to make you break your install again, so don't feel obliged to try
