Code Refactoring

  • make code promisify free (23de2e4)

BREAKING CHANGES

  • Everyone upgrading to this release also needs to upgrade ipfs-block-service, ipfs-repo and ipld-in-memory.

This commit uses the new async API of:

  • ipfs-block-service >= 0.16.0
  • ipfs-repo >=0.27.0
  • ipld-in-memory >= 3.0.0

If your library has a dependency on any of those, you likely also need to upgrade to at least those versions.

BREAKING CHANGES

  • v1 CIDs now default to base32 encoding

Previous versions returned a base58 encoded string when toString()/ toBaseEncodedString() was called on a CIDv1. It now returns a base32 encoded string.

0.23.0 (2019-05-08)

Bug Fixes

  • use the cleaned up IPLD Format API (108aef0)

BREAKING CHANGES

The most important change is that now all formats return links as CID instances and no longer as the JSON representation ({"/": "base-encoded-cid"}.

0.22.0 (2019-03-21)

Bug Fixes

  • add dynamically loaded format via addFormat() (95536cd)
  • don't throw if it's not a proper old-style link (38be898)
  • error if loadFormat() is not a function (4ad1ee4)
  • use a version of typical where async iterators are supported (43176ca)

  • implementation of the new get() function (743e679)
  • implementation of the new put() function (8b737b1)
  • implementation of the new remove() function (08c1e0e)
  • implementation of the new resolve() function (162473b)
  • implementation of the new tree() function (9801765)
  • make addFormat() and removeFormat() return the instance (5f62fe0)

BREAKING CHANGES

  • put/get/remove functions are renamed

This commit introduces single item functions which are called put()/get(),remove().

In order to put, get or remove multiple items you need to call putMany(),getMany()/removeMany() now.

  • This replaces the treeStream() function.

The API docs for it:

Returns all the paths that can be resolved into.

  • cid (CID, required): the CID to get the paths from.
  • path (IPLD Path, default: ''): the path to start to retrieve the other paths from.
  • options:
    • recursive (bool, default: false): whether to get the paths recursively or not. false resolves only the paths of the given CID.

Returns an async iterator of all the paths (as Strings) you could resolve into.

  • They replace the support.add() and support.rm() functions.

The API docs for it:

.addFormat(ipldFormatImplementation):

Add support for an IPLD Format

  • ipldFormatImplementation (IPLD Format, required): the implementation of an IPLD Format.

.removeFormat(codec):

Remove support for an IPLD Format

  • codec (multicodec, required): the codec of the IPLD Format to remove.
  • remove() has a new API.

The API docs for it:

Remove IPLD Nodes by the given cids

  • cids (Iterable<CID>): the CIDs of the IPLD Nodes that should be removed.

Throws an error if any of the Blocks can’t be removed. This operation is not atomic, some Blocks might have already been removed.

  • get() is replacing the getMany() function.

The API docs for it:

Retrieve several IPLD Nodes at once.

  • cids (Iterable<CID>): the CIDs of the IPLD Nodes that should be retrieved.

Returns an async iterator with the IPLD Nodes that correspond to the given cids.

Throws an error if a IPLD Node can’t be retrieved.

  • The API of put() changes.

The API docs for it:

Stores the given IPLD Nodes of a recognized IPLD Format.

  • nodes (Iterable<Object>): deserialized IPLD nodes that should be inserted.
  • format (multicodec, required): the multicodec of the format that IPLD Node should be encoded in.
  • options is applied to any of the nodes and is an object with the following properties:
    • hashAlg (multicodec, default: hash algorithm of the given multicodec): the hashing algorithm that is used to calculate the CID.
    • cidVersion (boolean, default: 1): the CID version to use.
    • onlyHash (boolean, default: false): if true the serialized form of the IPLD Node will not be passed to the underlying block store.

Returns an async iterator with the CIDs of the serialized IPLD Nodes.

  • The codec parameter in options.loadFormat() is a number

Instead of returnign the name of the codec as string, the codec code (a number) is now returned.

So if you e.g. check within the function for a certain format, it changes from:

async loadFormat (codec) {
  if (codec !== 'dag-cbor') …
}

To:

async loadFormat (codec) {
  if (codec !== multicodec.DAG_CBOR) …
}
  • your custom format loading function needs to be an async now.

So the signature for options.loadFormat is no longer:

function (codec, callback)

but

async functiont (codec)

  • resolve() replaces parts of get().

The API docs for it:

Retrieves IPLD Nodes along the path that is rooted at cid.

  • cid (CID, required): the CID the resolving starts.
  • path (IPLD Path, required): the path that should be resolved.

Returns an async iterator of all the IPLD Nodes that were traversed during the path resolving. Every element is an object with these fields:

  • remainderPath (string): the part of the path that wasn’t resolved yet.
  • value (*): the value where the resolved path points to. If further traversing is possible, then the value is a CID object linking to another IPLD Node. If it was possible to fully resolve the path, value is the value the path points to. So if you need the CID of the IPLD Node you’re currently at, just take the value of the previously returned IPLD Node.

0.21.0 (2019-01-16)

Code Refactoring

BREAKING CHANGES

  • This module no longer exports an inMemory utility to create an IPLD instance that uses a block service that stores data in memory. Please use the ipld-in-memory module instead.

Features

  • fail fast for missing format (ebd2d1b)

0.19.1 (2018-10-27)

0.19.0 (2018-10-25)

Code Refactoring

  • make blockService an option parameter (f1c2e12)
  • pass in IPLD Formats into the constructor (b003ad1)

BREAKING CHANGES

  • Not all IPLD Formats are included by default

By default only the ipld-dag-cbor, ipld-dag-pb and [raw] IPLD Formats are included. If you want to use other IPLD Formats you need to pass them into the constructor.

The code to restore the old behaviour could look like this:

const ipldBitcoin = require('ipld-bitcoin')
const ipldDagCbor = require('ipld-dag-cbor')
const ipldDagPb = require('ipld-dag-pb')
const ipldEthAccountSnapshot = require('ipld-ethereum').ethAccountSnapshot
const ipldEthBlock = require('ipld-ethereum').ethBlock
const ipldEthBlockList = require('ipld-ethereum').ethBlockList
const ipldEthStateTrie = require('ipld-ethereum').ethStateTrie
const ipldEthStorageTrie = require('ipld-ethereum').ethStorageTrie
const ipldEthTrie = require('ipld-ethereum').ethTxTrie
const ipldEthTx = require('ipld-ethereum').ethTx
const ipldGit = require('ipld-git')
const ipldRaw = require('ipld-raw')
const ipldZcash = require('ipld-zcash')

…

const ipld = new Ipld({
  blockService: blockService,
  formats: [
    ipldBitcoin, ipldDagCbor, ipldDagPb, ipldEthAccountSnapshot,
    ipldEthBlock, ipldEthBlockList, ipldEthStateTrie, ipldEthStorageTrie,
    ipldEthTrie, ipldEthTx, ipldGit, ipldRaw, ipldZcash
  ]
})
  • The IPLD constructor is no longer taking a BlockService as its only parameter, but an objects object with blockService as a key.

You need to upgrade your code if you initialize IPLD.

Prior to this change:

const ipld = new Ipld(blockService)

Now:

const ipld = new Ipld({blockService: blockService})

0.18.0 (2018-10-12)

BREAKING CHANGES

  • The API for dag-cbor changed. Links are no longer represented as JSON objects ({"/": "base-encoded-cid"}, but as CID objects. get() and getStream() now always return links as CID objects. put() also takes CID objects as input. Link represented as old-style JSON objects is still supported, but deprecated.

Example:

Prior to this change:

const cid = new CID('QmXed8RihWcWFXRRmfSRG9yFjEbXNxu1bDwgCFAN8Dxcq5')
ipld.put({link: {'/': cid.toBaseEncodedString()}}, {format: 'dag-cbor'}, (err, putCid) => {
  ipld.get(putCid, (err, result) => {
      console.log(result.value)
  })
})

Output:

{ link:
   { '/':
      <Buffer 12 20 8a…> } }

Now:

const cid = new CID('QmXed8RihWcWFXRRmfSRG9yFjEbXNxu1bDwgCFAN8Dxcq5')
ipld.put({link: cid}, {format: 'dag-cbor'}, (err, putCid) => {
  ipld.get(putCid, (err, result) => {
      console.log(result.value)
  })
})

Output:

{ link:
   CID {
     codec: 'dag-pb',
     version: 0,
     multihash:
      <Buffer 12 20 8a…> } }

See ipld/ipld#44 for more information on why this change was made.
