Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. -'use strict'; - -module.exports = Transform; - -var _require$codes = require('../errors').codes, - ERR_METHOD_NOT_IMPLEMENTED = _require$codes.ERR_METHOD_NOT_IMPLEMENTED, - ERR_MULTIPLE_CALLBACK = _require$codes.ERR_MULTIPLE_CALLBACK, - ERR_TRANSFORM_ALREADY_TRANSFORMING = _require$codes.ERR_TRANSFORM_ALREADY_TRANSFORMING, - ERR_TRANSFORM_WITH_LENGTH_0 = _require$codes.ERR_TRANSFORM_WITH_LENGTH_0; - -var Duplex = require('./_stream_duplex'); - -require('inherits')(Transform, Duplex); - -function afterTransform(er, data) { - var ts = this._transformState; - ts.transforming = false; - var cb = ts.writecb; - - if (cb === null) { - return this.emit('error', new ERR_MULTIPLE_CALLBACK()); - } - - ts.writechunk = null; - ts.writecb = null; - if (data != null) // single equals check for both `null` and `undefined` - this.push(data); - cb(er); - var rs = this._readableState; - rs.reading = false; - - if (rs.needReadable || rs.length < rs.highWaterMark) { - this._read(rs.highWaterMark); - } -} - -function Transform(options) { - if (!(this instanceof Transform)) return new Transform(options); - Duplex.call(this, options); - this._transformState = { - afterTransform: afterTransform.bind(this), - needTransform: false, - transforming: false, - writecb: null, - writechunk: null, - writeencoding: null - }; // start out asking for a readable event once data is transformed. - - this._readableState.needReadable = true; // we have implemented the _read method, and done the other things - // that Readable wants before the first _read call, so unset the - // sync guard flag. - - this._readableState.sync = false; - - if (options) { - if (typeof options.transform === 'function') this._transform = options.transform; - if (typeof options.flush === 'function') this._flush = options.flush; - } // When the writable side finishes, then flush out anything remaining. - - - this.on('prefinish', prefinish); -} - -function prefinish() { - var _this = this; - - if (typeof this._flush === 'function' && !this._readableState.destroyed) { - this._flush(function (er, data) { - done(_this, er, data); - }); - } else { - done(this, null, null); - } -} - -Transform.prototype.push = function (chunk, encoding) { - this._transformState.needTransform = false; - return Duplex.prototype.push.call(this, chunk, encoding); -}; // This is the part where you do stuff! -// override this function in implementation classes. -// 'chunk' is an input chunk. -// -// Call `push(newChunk)` to pass along transformed output -// to the readable side.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. +'use strict'; -exports.codes = Object.freeze({ -

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. + var uploadDirectory = function uploadDirectory(swarmUrl) { + return function (directory) { + return uploadData(swarmUrl)("{}").then(function (hash) { + var uploadRoute = function uploadRoute(route) { + return function (hash) { + return uploadToManifest(swarmUrl)(hash)(route)(directory[route]); + }; + }; -'use strict'; + var uploadToHash = function uploadToHash(hash, route) { + return hash.then(uploadRoute(route)); + }; -module.exports = Transform; + return Object.keys(directory).reduce(uploadToHash, Promise.resolve(hash)); + }); + }; + }; // String -> Promise String -var Duplex = require('./_stream_duplex'); -/**/ -var util = require('core-util-is'); -util.inherits = require('inherits'); -/**/ + var uploadDataFromDisk = function uploadDataFromDisk(swarmUrl) { + return function (filePath) { + return fs.readFile(filePath).then(uploadData(swarmUrl)); + }; + }; // String -> Nullable String -> String -> Promise String -util.inherits(Transform, Duplex); -function afterTransform(er, data) { - var ts = this._transformState; - ts.transforming = false; + var uploadDirectoryFromDisk = function uploadDirectoryFromDisk(swarmUrl) { + return function (defaultPath) { + return function (dirPath) { + return files.directoryTree(dirPath).then(function (fullPaths) { + return Promise.all(fullPaths.map(function (path) { + return fs.readFile(path); + })).then(function (datas) { + var paths = fullPaths.map(function (path) { + return path.slice(dirPath.length); + }); + var types = fullPaths.map(function (path) { + return mimetype.lookup(path) || "text/plain"; + }); + return toMap(paths)(datas.map(function (data, i) { + return { + type: types[i], + data: data + }; + })); + }); + }).then(function (directory) { + return merge(defaultPath ? { + "": directory[defaultPath] + } : {})(directory); + }).then(uploadDirectory(swarmUrl)); + }; + }; + }; // String -> UploadInfo -> Promise String + // Simplified multi-type upload which calls the correct + // one based on the type of the argument given. - var cb = ts.writecb; - if (!cb) { - return this.emit('error', new Error('write callback called multiple times')); - } + var _upload = function upload(swarmUrl) { + return function (arg) { + // Upload raw data from browser + if (arg.pick === "data") { + return pick.data().then(uploadData(swarmUrl)); // Upload a file from browser + } else if (arg.pick === "file") { + return pick.file().then(uploadFile(swarmUrl)); // Upload a directory from browser + } else if (arg.pick === "directory") { + return pick.directory().then(uploadDirectory(swarmUrl)); // Upload directory/file from disk + } else if (arg.path) { + switch (arg.kind) { + case "data": + return uploadDataFromDisk(swarmUrl)(arg.path); - ts.writechunk = null; - ts.writecb = null; + case "file": + return uploadFileFromDisk(swarmUrl)(arg.path); - if (data != null) // single equals check for both `null` and `undefined` - this.push(data); + case "directory": + return uploadDirectoryFromDisk(swarmUrl)(arg.defaultFile)(arg.path); + } - cb(er); + ; // Upload UTF-8 string or raw data (buffer) + } else if (arg.length || typeof arg === "string") { + return uploadData(swarmUrl)(arg); // Upload directory with JSON + } else if (arg instanceof Object) { + return uploadDirectory(swarmUrl)(arg); + } - var rs = this._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - this._read(rs.highWaterMark); - } -} + return Promise.reject(new Error("Bad arguments")); + }; + }; // String -> String -> Nullable String -> Promise (String | Uint8Array | Map String Uint8Array) + // Simplified multi-type download which calls the correct function based on + // the type of the argument given, and on whether the Swwarm address has a + // directory or a file. -function Transform(options) { - if (!(this instanceof Transform)) return new Transform(options); - Duplex.call(this, options); + var _download = function download(swarmUrl) { + return function (hash) { + return function (path) { + return isDirectory(swarmUrl)(hash).then(function (isDir) { + if (isDir) { + return path ? downloadDirectoryToDisk(swarmUrl)(hash)(path) : downloadDirectory(swarmUrl)(hash); + } else { + return path ? downloadDataToDisk(swarmUrl)(hash)(path) : downloadData(swarmUrl)(hash); + } + }); + }; + }; + }; // String -> Promise String + // Downloads the Swarm binaries into a path.
