Unable to PIN existing CID in IPFS browser node

[logesh2496]

Pinning only works If I upload some data using unixfs and then use that CID. I couldn't pin a CID thats already available on ipfs.

So how do I use a CID thats already available on ipfs and pin it in my node?

example: I want to pin this CID: QmRrzxiXGefcF9VbbThGrkhiQeuhPFjRbGgqYZmxYXYkHr on my node

At the moment Im getting the below error:

errors.js:27 Uncaught (in promise) Error: Not Found at Module.notFoundError (errors.js:27:1) at MemoryBlockstore.get (memory.js:19:19) at #walkDag (pins.js:97:1) at eval (pins.js:52:1) at eval (index.js:111:1) at PQueue._PQueue_tryToStartAnother (index.js:285:1) at eval (index.js:135:1) at new Promise () at PQueue.add (index.js:99:1) at PinsImpl.add (pins.js:51:1) at async onPin (ipfs.js:69:17)

Can you please share a full repro case please? Pinning will fetch missing blocks from the network but the error thrown looks like you may be running offline or it could be unrelated.

I'm working on the nextjs examples provided in the helia-examples/helia-nextjs

export default async function getLibp2p ({ datastore }) {
  return await createLibp2p({
    datastore,
    addresses: {
      listen: [
        '/webrtc'
      ],
    },
    transports: [
      webSockets(),
      webRTC()
    ],
    connectionEncryption: [
      noise()
    ],
    streamMuxers: [
      yamux()
    ],
    services: {
      identify: identifyService()
    }
  })
}

const blockstore = new MemoryBlockstore()
const datastore = new MemoryDatastore()

const libp2p = await getLibp2p({ datastore })

// create a Helia node
return await createHelia({
  datastore,
  blockstore,
  libp2p
})

const cid = CID.parse('QmRrzxiXGefcF9VbbThGrkhiQeuhPFjRbGgqYZmxYXYkHr');
const pin = await helia.pins?.add(cid);
//Error here

[achingbrain]

Ah, I think there was a small bug with how the internal blockstores were being created - please can you try with [email protected]?

[logesh2496]

That worked, thanks! btw is there any option to get progress from the pin operation? It takes a alot of time and the UI is waiting cluelessly, it would be great to have a progress bar that shows the % downloaded.

So How do I know how much of the content is downloaded, Thanks again!

[achingbrain]

Almost every API accepts a onProgress event callback with information about the current operation.

Note that it's impossible to know in advance how big a DAG is, unless it's part of the codec or data encoding.

For example @helia/unixfs has a .stat method that will return the UnixFS metadata from the root node that you can use before pinning to see how big the DAG is, but other codecs like dag-cbor may not provide this feature.

[logesh2496]

Tried, but it isn't working. Below is the code:

const cid = CID.parse('QmVXy4WyMaz4ajm2LUUjyu33cH7UDdytHvctdYmchdvdMy')

    const pin = await helia.pins.add(cid, {
        onProgress: (evt) => {
        console.info('pin event', evt.type, evt.detail)
      }
    });

You can try with the same CID, its an image and I expected to see some progress but didn't do anything, and no error too.

[logesh2496]

@achingbrain any help here?

[whizzzkid]

@logesh2496 I tried your example, but CustomProgressEvent ~~does not have detail property~~ has the detail property, but the value is generic according to the event type, so modifying your example gives me:

const testcid = CID.parse('QmVXy4WyMaz4ajm2LUUjyu33cH7UDdytHvctdYmchdvdMy')

const pin = await helia.pins.add(testcid, {
    onProgress: (evt) => console.log('pin event', evt)
});

and I get:

Reiterating what @achingbrain said before, it would be hard to use this to create a progress bar, but seems to work as expected. Can you please share a repo/pr where this fails?

[achingbrain]

CustomProgressEvent does not have detail property

Yes it does, but the value is generic according to the event type.

[logesh2496]

Thanks @achingbrain & @whizzzkid for taking the time to resolve my query.

However the method pins.add() itself wasn't working in the 1.2.1 version. I noticed that many changes had been made to the helia-examples for nextjs now: https://github.com/ipfs-examples/helia-examples/commit/ccc40f0546eee8d9124a46f7f7651296577c365a

So I updated the helia package version to 1.3.2 and removed getLibp2p as shown in the current examples repo to keep it simple. I do get some events now, but it errors out pretty quickly:

I understand that the event types are generic. Where can I read about all the event types during the pinning operation? any events related to the below list could be helpful for better UX.

• Pinning Started
• Pinning Completed
• Pinning Errored

Questions:

1. Pinning doesn't work and errors.
2. Does helia package provide the above-listed event types? & reference to all other event types during pinning operation.

Thanks.

[marten-seemann]

@logesh2496 Are you sure these nodes are online? The errors look like handshake timeouts, which you'd expect to see if the nodes has gone offline.

[github-actions[bot]]

Oops, seems like we needed more information for this issue, please comment with more details or this issue will be closed in 7 days.

[logesh2496]

the page still shows the status of the node as "Online"

[achingbrain]

No, Marten means the remote nodes, the ones being connected to.

[logesh2496]

ah, got it. Shouldn't it find another node that has a copy of the file? How do I handle this situation where I need to pin a file?

[SgtPooki]

I can't seem to get files to pin using helia either

[BigLep]

@SgtPooki : what repo case were you trying? (I just want to make sure we're all trying the same thing.)

[SgtPooki]

what repo case were you trying? (I just want to make sure we're all trying the same thing.)

I can't remember at the moment but I will come back to this when I can
