Rclone + beets


#1

BACKGROUND

  • VPS (4 vCPU, 16GB RAM, 80GB SSD)
  • Dockerized beets
  • rclone v1.42

rclone makes two folders, both on Google Drive, available to the beets container. _beets-import holds music that needs to be tagged, while _beets-export is where tagged and corrected music is moved.

ISSUE

When I try to run an import from one folder and export to the other, I get a bunch of errors from beets. rclone does not generate any errors.

QUESTION
What sort of issue does [Errno 9] Bad file descriptor actually indicate?


#2

Odd! This is an operating system error, so it’s not really something beets-specific we can answer. You can find lots of info on what this error means on SO, for example: https://stackoverflow.com/questions/11258781/bad-file-descriptor-with-linux-socket-write-bad-file-descriptor-c

Have you tried it outside of Docker?


#3

Unfortunately I have not had a chance to try it outside of Docker.

Based on what I’m seeing the problems seem to be happening when metadata gets written to the files, after they’ve been moved to their new location. Is there a way to reverse the process and have the metadata writes happen first, followed by the move?


#4

No, there’s not a way to reverse that. If you want, you could try disabling the import.write option altogether, and then manually running beet write to update metadata later.


#5

Or, I suppose, you could do the opposite and disable moving/copying—then use beet move later.


#6

OK, I think I got it sorted. Basically I’m using beet import to move the music from Google Drive to a local location for metadata writes, then using beet move -d /directory to move them into a different folder on Google Drive. It works well so far.

One further question:

My rename setup is configured as such -

paths:
    default: %upper{%left{$album,1}}/$album%aunique{}/$disc_track. $title
item_fields:
    disc_track: u'%i-%02i' % (disc, track) if disctotal > 1 else u'%02i' % (track)

Right now this means that albums with non A-Z characters make their own folder. I have a catch-all folder setup # where I manually move albums that don’t have actual letter for the first character, but I’d like to build that logic into the renaming string.

I would like to replace

%upper{%left{$album,1}}

with something that will place all albums without a letter for the first character (A-Z) into the # folder, while all other albums are filed normally per that part of the paths command.

I’m after something like this.

if{left{album,1}=[a-z]},upper{left{album,1}},'#'}

Hopefully that makes sense.


#7

For complex logic like that, please check out the inline plugin, which lets you use Python code to express what you want to happen. You might also be interested in the bucket plugin.


#8

Alright, thanks for the help!


#9

OK, I’m really close to having it figured out but I’m stuck on the regex part, '^[A-Za-z]'. Basically I’m trying to say “if the first letter of the album is anything A-Z or a-z, capitalize it and use it, otherwise use #.”

album[:1].capitalize() if album[:1] is '^[A-Za-z]' else '#'

The problem I’m running into is that everything is falling under else and returning #, even strings that have A-Z/a-z first characters.

  1. Can I even use regex in the Inline plugin? All the material I’m reading online states that a re module has to be loaded for regex to work (right now I’m testing this in python3 on my VPS; once that’s done I’ll move it to Inline).
  2. Can you think of an easier/alternative way to accomplish this? Today was basically the first time I’ve ever tried to do anything in Python and I’m really lost now.

#10

Yep! As the docs say, you can use multi-line Python code, which allows you to write import re and use the module. I can’t write the code for you, but I bet you can get it!


#11

Alright, I got it to work in Python

album[:1].capitalize() if re.match(r"^[A-Za-z]",album) else '#'

and added it to my config.yaml

paths:
    default: $first_letter/$album%aunique{}/$disc_track. $title

item_fields:
    disc_track: u'%i-%02i' % (disc, track) if disctotal > 1 else u'%02i' % (track)
    first_letter: |
            import re
            album[:1].capitalize() if re.match(r"^[A-Za-z]",album) else '#'

But when I go to move files, I encounter a permissions error.

docker exec -it -u abc beets bash -c 'beet move -d /temp/import2 album:45:33'
Moving 8 items.
Error: Permission denied while creating /45_33 Remixes

If I use my original path: option, it works

paths:
    default: %upper{%left{$album,1}}/$album%aunique{}/$disc_track. $title
docker exec -it -u abc beets bash -c 'beet move -d /temp/import2 album:45:33'
Moving 8 items.

Any ideas?
[EDIT] - It looks like I need to return the value so beets can actually use it. Back to Google.


#12

Well. Spent most of my day trying to cram return values into my Inline block. Managed to get it figured out.

item_fields:
    disc_track: u'%i-%02i' % (disc, track) if disctotal > 1 else u'%02i' % (track)
    first_letter: |
            import re
            def first_letter(album):
                if re.match(r"^[A-Za-z]",album):
                    return album[:1].capitalize()
                else:
                    return '#'

But I still get permission errors when trying to move or import albums

docker exec -it -u abc beets bash -c 'beet move -d /temp/import2 album:45:33'
Moving 8 items.
Error: Permission denied while creating /45_33 Remixes

I thought to myself “Ho ho, hold my beer I’ve got this,” and ran the same command as root from within the container. The files moved alright, but now they’re not visible in the folder.

root@fc31a34686a9:/temp/import2$ ls -la
total 8
drwxrwxr-x 2 abc users 4096 Aug 27 23:48 .
drwxrwxr-x 9 abc users 4096 Aug 27 23:50 ..

Not sure what to do.


#13

These problems really sound like issues with the container setup—it’s very difficult to see from here how beets is involved with them. You might try manually manipulating files in there, for example, or taking a look at beets’s verbose log for clues.
