File limit 250kb

Type: Bug

Severity: High

Description:

I use js-ipfs for this project https://github.com/osliki/classi with following configs:

const config = {
    repo: 'osliki-classi',
    start: true,
    EXPERIMENTAL: {
      pubsub: true,
      relay: {
        enabled: true,
        hop: {
          enabled: true,
        }
      }
    },
    config: {
      Addresses: {
        Swarm: [
          '/dns4/wrtc-star.discovery.libp2p.io/tcp/443/wss/p2p-webrtc-star',
          '/dns4/ws-star.discovery.libp2p.io/tcp/443/wss/p2p-websocket-star',
        ]
      }
    }
  }

and seems like nodes unable to share photos larger than 250kB. Starting from here for such large files I got everlasting loading.

Thanks for any help!

Hey @Artod are you sure it's the file size that's the issue? Do you have an example of a working image that is less than 250kB? Are you sure these hashes are available on the network?

[Artod]

Hi @alanshaw. They are not available on network but available between browser nodes.

Example:

1. Go here https://osliki.github.io/classi/
2. Click "New 'all' column"
3. If I will be online, you will see all images except 6th "Photo by Kaci Baum on U...".

I've tested:

• Laptop A + Chrome <=> Laptop A + Firefox
• Laptop A + Chrome <=> Laptop B + Chrome

Also you can clone repo, yarn install, yarn start (MetaMask on Rinkeby) and test it from different browsers locally.

About availability on network: if I got right, I need run my own go-ipfs node and, each time user uploads a file in the browser, make go-ipfs node fetch this file from the browser node. Correct?

Thank you!

@alanshaw small update.

I ran own go-ipfs node and added /dns4/bootstrap.osliki.net/tcp/443/wss/ipfs/QmfJB77qXfiEdJkaSxpZgiMh9kAPiDBj3ga7TxF72QdWtf to the config. Each time an user uploads photos in the browser, I make requests to the gateway of my go-ipfs node https://gateway.osliki.net/ipfs/${hash}, so files (including big ones) become available on the network and all browser nodes .

But issue is still relevant for the case

browser_node_A <= file_larger_than_250kB => browser_node_B

(when the go-ipfs node is down)

[alanshaw]

I'll look into this as soon as I get a sec. Can you please verify for me that this only happens for files larger than 250kB, and works fine for files that are smaller?

[Artod]

@alanshaw I've created a test page for testing https://osliki.github.io/250kb/

• Open the link in different browsers
• Select an img in the first browser
• Copy the hash
• Paste the hash in the second browser

Images larger than 250kb won't be loaded

This is exactly what I submitted here: #1307

This currently works, as shown in this example, which is hooked up to CI and tested with every js-ipfs change:

@AquiGorka and @Artod can you confirm whether or not is still a problem for you? Should be working in contemporary versions!

[Artod]

@autonome My project where I used ipfs is closed for now, so I can't verify if it's still a problem. Feel free to close the issue if you sure everything is fine. Thank you for the update.

[AquiGorka]

Hey @autonome thanks for the update, I remember talking to @jacobheun about this and he said it was on his radar. My project where this was a bug is also closed now, but I'm very happy this was solved. Cheers 🎉

Closing as it seems like this issue was resolved.
