gpodder doesn't show subscriptions since SFOS 4.5.0

[dimpflmoser]

Yesterday I upgraded to SFOS 4.5.0.? Since then, gpodder v 4.12.90 doesn't show its subscriptions anymore.

This is the output I get on the shell without invoker / firejail:

As a workaround I checked the list of subscribed podcasts with sqlite3 and re-added one of the podcasts via UI. This brought back the whole list of podcasts.

After I close and re-open gpodder the situation repeats, list of subscribed podcasts is empty, I need to add a new podcast to recover the list.

Hey thanks for reporting!

I just updated my phone to 4.5.0.16 and was not able to reproduce the issue you had, I do need to allow gPodder some time to read the database but after that it displays everything (23 podcasts almost 3k episodes), can you try re-installing maybe the install got messed up by the update?

I will try and run from CLI tomorrow to see if I get similar errors to you.

[dimpflmoser]

Hm, there are a few issues that may differ to your installation:

• my home is still on /home/nemo
• my application directory is on sdard and linked to internal memory

  [root@xa2 share]# ls -l /home/nemo/.local/share/harbour-org.gpodder.sailfish
  lrwxrwxrwx    1 root     root            94 Feb  5 13:03 /home/nemo/.local/share/harbour-org.gpodder.sailfish -> /run/media/nemo/1acba99f-a628-4c48-9e57-ba3d04f4817e/.local/share/harbour-org.gpodder.sailfish

  I realised the following behaviour:

• if I don't have the link to internal memory gpodder says that there wasn't any podcast subscribed and gpodder creates a new directory with Database.minidb.
• if I delete that newly created directory and recover the symbolic link the list with subscriptions is just empty, i.e. without the note that I didn't have any podcasts subscribed. Gpodder also finds and plays all downloaded episodes. It even shows fresh episodes

Reinstallation didn't make any change

Hi @dimpflmoser ! I'm on sfos 4.5.0.16 and I use symbolic link to my sdcard for downloading my podcasts, but I don't have this issue. It's weird, maybe it's a problem with your symbolic link or permissions to access your symbolic link?

[dimpflmoser]

Thanks for sharing your point.

As gpodder shows fresh and downloaded episodes and immediately shows the list of podcasts when I add a new one (even if the URL is invalid), I would bet that gpodder has full access to the database file. I got the impression that's some kind of race condition that the list of podcasts has not yet been (fully) read when the GUI starts presenting it. If there was another way to force reassembling the list there was a chance to get around this behaviour. This is what I try with adding a (false) podcast URL.

If I find some time, eventually, I'll try to backup/rename my old folder and create a new one to see whether this is related to my current configuration of podcasts & episodes or whether this is related to my phone setup.

@dimpflmoser do you still have issues? If not I want to close the issue since we're not able to reproduce.

[dimpflmoser]

I ran out of ideas and couldn't fix it. So I removed my database and restarted from scratch. It works since then with the new setup.
