error when loading playlist about gonic

[sentriz]

interesting. thanks for investigating :) by any change do you have any audio files in your root dir? eg /music/a.mp3?

[Byter09]

I do not. The only two interesting folders I have in there are !unsorted and .stfolder. The rest of them are alphanumerical so shouldn't cause any errors. I had these before though, so it once worked.
Could it be some file in an album that has some non-ascii chars? Haven't looked at the code yet. Just guessing at this point 😄

[sentriz]

hey could you try again with sentriz/gonic:latest again please and check the logs?

[Byter09]

Was kind of wondering why watchtower didn't already pull the latest one haha.

Am now on sentriz/gonic:latest@sha256:bba999e44b70256c21d5ac165fc981c1ab44fedd416e4244d5c354ccf5e1b34b

And it updates automatically as soon as you publish a new one :)

Same issue though :(

EDIT: Aaaand watchtower just pulled sha256:f3e05970af708efb4c638e9f3cb10ab9b602776bd954047b9b988d87b20e8159. Testing ...

[sentriz]

sorry I just pushed a new one. can you find b33734a0091ecb8e22b0fb36b6a5a7704bd10cad6ca758a4968b7d0744efa4e?

[sentriz]

ah yes f3... will do too

[Byter09]

Apart from

2020/05/26 18:06:46 wasn't able to find track with id 'Υ',

It appears to work fine now.

[Byter09]

Just had a look at the commit and the typical ID stuff in my logs. This... id is not supposed to be a letter... right? Is this somehow my fault?

[sentriz]

Oh is it a literal Y in your logs?

[Byter09]

I copied the above directly from my docker logs. So I assume yes.

[Byter09]

Do you maybe need my database or so? I assume nothing personal is in there so I have no trouble sharing it :)

EDIT: Oh right... usernames and passwords. They're hashed right? 😃

[sentriz]

they are not hashed unfortunately due to a limitation in the subsonic api. but you can make a copy of the db then $ sqlite3 path/to/dbcopy.db "delete from users" and that will remove it from the copy, then you could send that?

[Byter09]

There you go. I manually used a sqlite viewer to verify the user table was empty.

Note: The gonic.db has 1.2 MiB, the gonic.db-wal has 4.1 MiB. I'm not certain how exactly this works but I hope everything you need is in the .db file.

gonic.db.tar.gz

[sentriz]

thanks for the db! turns out that Y was a stupid mistake on my part (fixed now, you should get a real id)
but unfortunately this is a problem with gonic :( #54 is the same issue

[sentriz]

as something in the meantime, I need to make a mechanism to export playlists to m3u or something. that way we can have backups when the migration is written
