I made a video about copyparty, the selfhosted fileserver I've been making for the past 5 years.

The main focus of the video is the features, but it also touches upon configuration. Was hoping it would be easier to follow than the readme on github... not sure how well that went, but hey :D

This video is also available to watch on the copyparty demo server, as a high-quality AV1 file and a lower-quality h264.

Does anyone know if you can manage multiple devices from a single interface? If I had it on a couple of old phones and a laptop, for example.

[–] No_Bark@lemmy.dbzer0.com 1 points 2 days ago

This is incredible! I'm going to play around with this in my docker stack.

[–] freebee@sh.itjust.works 1 points 4 days ago

Wow.

This works crazy fast and performant. Keep up the incredible work!

[–] filcuk@lemmy.zip 5 points 6 days ago

This is insane. I think I'd use ten different applications and still not cover these features. And I can host this. Using a single python file.

I played around with copyparty and I have to say it is just awesome! The config is just fun to mess around with and everything feels snappy.

But I ran into an issue with FTP (probably just something I configured incorrectly) and could not find a discussion for that. I should probably start an issue on Github but as a non-developer I'm not sure how to do that in the correct way.

Edit: I managed to "solve" the problem. Apparently the user uploading to a subfolder over FTP needs the move permission for the folder above said subfolder.

I see flake.nix, i install.

You made this on your phone on the bus ride to and from work.

I cleaned the cat box yesterday and considered that an accomplishment.

Fuck.

[–] markstos@lemmy.world 15 points 1 week ago

Congrats on the cat box cleaning!

[–] johntash@eviltoast.org 45 points 1 week ago (1 children)

Your readme looks super in depth, thanks for that! I haven't watched the video yet but will later.

I didn't see it mentioned from a quick glance, but is either sftp or ftps supported?

[–] tripflag@lemmy.world 37 points 1 week ago (2 children)

SFTP is not currently on the roadmap, but it's not entirely implausible.

FTPS is supported, but it requires an optional dependency to be installed (pyopenssl), so it's not available in the Windows EXE. And I just realized that the dependency is currently not present inside the docker images either, so I'll get that fixed right away.

[–] xnx@slrpnk.net 9 points 1 week ago

Screenshots of the ui at the top of the readme would be nice

Clearly a labour of love 👍

Maybe support for some music streaming apps (subsonic?) would be cool?

[–] tripflag@lemmy.world 18 points 1 week ago (1 children)

That's a neat idea -- I've heard that a lot of stuff uses the subsonic API under the hood, so I'll see what it would take to become compatible with that. At first glance it looks like I'd have to mine and index way more information about audio files, but could still be doable :>

Hey fellow scener, cool project!

Just a few thoughts/questions:

  • BTRFS and ZFS support real deduplication via copy on write, and would eliminate all current disadvantages of symlink and hardlink deduplication. It just works.
  • Why have it be one huge python source file? This is a serious code smell imo, and something you really should avoid doing as this can be a major maintenance burden.
[–] tripflag@lemmy.world 28 points 1 week ago (6 children)

yeah that's a good point, I'll add an option to take advantage of this if you know you're running on a filesystem where that works as intended.

Why have it be one huge python source file?

oh don't worry, it's all separate files during development -- there's a build-stage which bundles everything up into a single file for distribution. But thanks for the concern :D

The fact you mention security features, without ever saying it's 'super secure' tells me you know a lot about what you're doing. I'm so sick of apps like this that start with "most secure app on the net" but you know they're delusional. Thank you, going to check this out.

Put out some in-depth docker instructions and this will be common use in a month. Good work.

[–] TehNomad@piefed.social 2 points 4 days ago (1 children)

The docker compose file worked great for me.

[–] KiwiTB@lemmy.world 1 points 4 days ago

They may have patched it. I'll check it out thanks.

Is there a way to help translate the UI.

I would like to help translate it into Danish.

[–] cows_are_underrated@feddit.org 12 points 1 week ago

Would also be willing to help translate the UI.

[–] buddascrayon@lemmy.world 16 points 1 week ago (1 children)

Holy shit this is so unbelievably full featured it's not even funny. This is going to rattle some big names. I wonder how long till they try to shut it down because it's better than anything commercially available.

[–] tiramichu@sh.itjust.works 15 points 1 week ago* (last edited 1 week ago)

I haven't even tried it yet, but just from the video you can tell it's going to be insanely good. I'm so impressed.

It's the first bit of software I've seen in a long time where I took one look and immediately thought "Fuck me, I need that!"

I use Unraid for my NAS server and just on the off-chance I checked the Unraid community 'app store' and someone's already created a Docker definition for it, published just today! The hype is real

I'll be giving this a shot

[–] pwalker@discuss.tchncs.de 15 points 1 week ago* (last edited 1 week ago) (1 children)

you even mention ladybird as browser, nice 😎

[–] tripflag@lemmy.world 19 points 1 week ago (2 children)

it's such an impressive project! Amazing what they've accomplished in so little time, and so important too -- we need as many options as we can get.

Oh my god, this seems really good and closer to what I want than anything yet. Been looking for something to replace Nextcloud and found nothing good so I might take a look at this.

I bumped into copyparty the other month when looking for a software that could let me transfer files to a friend with the ability to pause/resume. Didn't bother with it, tried another software instead. Never really got it to work so I gave up on it.

Bumped into the YouTube video today, decided to give copyparty a shot, damn sir you've written a fine piece of software. It's so easy to get up and configure. The UI is a bit janky, but charming at the same time. Thanks for all the hard work!

Thanks for making the video but also for providing non Youtube link. Maybe there is a PeerTube server that would enjoy hosting it.

[–] ayyy@sh.itjust.works 10 points 1 week ago (5 children)

Everyone loves CP. Tell all your friends about CP.

[–] atomicbocks@sh.itjust.works 10 points 1 week ago (1 children)

This looks great but I really wish it had SFTP.

[–] tripflag@lemmy.world 11 points 1 week ago

thanks for the vote, I hear ya :>

[–] jlh@lemmy.jlh.name 10 points 1 week ago (2 children)

I would probably remove python 2 support, it was end of life when the project was started.

[–] tripflag@lemmy.world 15 points 1 week ago (1 children)

As long as it's not causing any issues or drawbacks for modern python versions (and it isn't), I don't see any reason to do that -- on the contrary, I know people are running copyparty on retro equipment, so I'd very much prefer to keep it for as long as possible :>

I have a question, and I want to emphasise thar this is not criticism but a request for dive into technicalities.

In the video you mentioned copyparty has an one-way sync tool. Is there a good reason why it's not two-way, or is this just something you weren't motivated to do?

[–] tripflag@lemmy.world 17 points 1 week ago (4 children)

No worries, good question :>

The problem with bidirectional filesync is that it's an absolutely massive can of worms, very easy to mess up, and the consequences of messing up are usually the worst kind (loss of data). There's an insane amount of edgecases to keep in mind, and you need to get every edgecase right every single time, otherwise you might wipe someone's vacation photos, or suddenly downgrade someone's keepass database to an older version... And stuff like syncing multiple devices to the same server makes it balloon further.

I've started becoming more confident in copyparty's filesystem-index database, but it's still just a hint/guideline, with the filesystem being the only source of truth -- it's still not something I'd trust with tracking sync-state against one or more clients.

The bigger guys who offer bidirectional sync (nextcloud, syncthing, etc.) have spent years perfecting their logic, so I'd like to leave this in their capable hands.

[–] null_dot@lemmy.dbzer0.com 9 points 1 week ago

Sync is one of those things that seems like it should be trivial but is actually super complicated.

Ho... Ly... Shit... This is great! The UI is a bit confusing at first but doesn't take long to get what's going on. I might even be disappointed with a UI revamp 😁 I can't believe how much functionality this has. It's already replacing some processes I have for mounting drives and backing up files. Maybe I missed something, but my only complaint would be the lack of an automatic one-way folder sync in the Party UP! app.

I'm blown away, great job!

That "functional but charming" UI reminds me of audiobookshelf with the soundleaf app - same vibe where it dosn't look fancy but gets the job done better than most polished alternatives!

[–] craftrabbit@lemmy.zip 9 points 1 week ago

Don't believe it. This is easily too good to be true.

[–] danhab99@programming.dev 9 points 1 week ago (1 children)

Oh my gawd what a README!! I'm on my phone and I was trying to scroll back to the top of it from the bottom and I just kept on scrolling... Holy shit I'm going to put this on my kanban board give it proper attention

Well done! This is exactly what I've been looking for! And it's fun to use and has an aesthetic that reminds me of browsing ftp servers back in the day. And these themes?! I love the whimsy mixed with actual usability.

And its a damn good file server so far: fast, easy to use, makes reasonable security choices, and accessible in the ways I want (rclone mount)

[–] tux0r@feddit.org 8 points 1 week ago (2 children)

Can we have Gopher support?
