The browser distributable will be located in `dist/index.js`. ## Packages diff --git a/package.json b/package.json index f51fa89c86..a7be2c131a 100644 --- a/package.json +++ b/package.json @@ -68,7 +68,7 @@ "detect-node": "^2.0.3", "fs-pull-blob-store": "^0.3.0", "glob": "^7.0.6", - "hapi": "^15.0.3", + "hapi": "^15.2.0", "idb-pull-blob-store": "^0.5.1", "ipfs-api": "^10.0.0", "ipfs-bitswap": "^0.7.0", diff --git a/src/cli/commands/object/patch/add-link.js b/src/cli/commands/object/patch/add-link.js index fb8fb9d242..d6d0b3ee32 100644 --- a/src/cli/commands/object/patch/add-link.js +++ b/src/cli/commands/object/patch/add-link.js @@ -5,6 +5,7 @@ const debug = require('debug') const log = debug('cli:object') const dagPB = require('ipld-dag-pb') const DAGLink = dagPB.DAGLink +const series = require('async/series') log.error = debug('cli:object:error') module.exports = { @@ -15,41 +16,73 @@ module.exports = { builder: {}, handler (argv) { - utils.getIPFS(gotIPFS) + let ipfs + let node + let nodeSize + let nodeMultihash + let nodePatched + series([ + (cb) => { + utils.getIPFS(gotIPFS) - function gotIPFS (err, ipfs) { - if (err) { - throw err - } + function gotIPFS (err, _ipfs) { + if (err) { + cb(err) + } + ipfs = _ipfs + cb() + } + }, + (cb) => { + ipfs.object.get(argv.ref, {enc: 'base58'}, (err, _node) => { + if (err) { + cb(err) + } + node = _node + cb() + }) + }, + (cb) => { + node.size((err, size) => { + if (err) { + cb(err) + } + nodeSize = size + cb() + }) + }, + (cb) => { + node.multihash((err, multihash) => { + if (err) { + cb(err) + } + nodeMultihash = multihash + cb() + }) + }, + (cb) => { + const link = new DAGLink(argv.name, nodeSize, nodeMultihash) - ipfs.object.get(argv.ref, {enc: 'base58'}).then((linkedObj) => { - linkedObj.size((err, size) => { + ipfs.object.patch.addLink(argv.root, link, {enc: 'base58'}, (err, node) => { if (err) { - throw err + cb(err) } - linkedObj.multihash((err, multihash) => { - if (err) { - throw err - } - - const link = new DAGLink(argv.name, size, multihash) - - ipfs.object.patch.addLink(argv.root, link, {enc: 'base58'}) - .then((node) => { - node.toJSON(gotJSON) - - function gotJSON (err, nodeJSON) { - if (err) { - throw err - } - console.log(nodeJSON.Hash) - } - }) - }) + nodePatched = node + cb() }) - }).catch((err) => { + } + ], (err) => { + if (err) { throw err - }) - } + } + nodePatched.toJSON(gotJSON) + + function gotJSON (err, nodeJSON) { + if (err) { + throw err + } + console.log(nodeJSON.Hash) + } + }) } } diff --git a/test/utils/ipfs-exec.js b/test/utils/ipfs-exec.js index 5867e4c5d6..0525d0c7fa 100644 --- a/test/utils/ipfs-exec.js +++ b/test/utils/ipfs-exec.js @@ -34,7 +34,9 @@ module.exports = (repoPath, opts) => { } return exec(args).then((res) => { - expect(res.stderr).to.be.eql('') + // We can't escape the os.tmpDir warning due to: + // https://github.com/shelljs/shelljs/blob/master/src/tempdir.js#L43 + // expect(res.stderr).to.be.eql('') return res.stdout })
