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'; - for (var i = 0; i < 4; i++) { - var Qprime; - try { - Qprime = this.recoverPubKey(e, signature, i); - } catch (e) { - continue; - } +module.exports = Transform; - if (Qprime.eq(Q)) - return i; - } - throw new Error('Unable to find valid recovery factor'); -}; +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; -},{"../../elliptic":83,"./key":91,"./signature":92,"bn.js":20}],91:[function(require,module,exports){ -'use strict'; +var Duplex = require('./_stream_duplex'); -var BN = require('bn.js'); +require('inherits')(Transform, Duplex); -function KeyPair(ec, options) { - this.ec = ec; - this.priv = null; - this.pub = null; +function afterTransform(er, data) { + var ts = this._transformState; + ts.transforming = false; + var cb = ts.writecb; - // KeyPair(ec, { priv: ..., pub: ... }) - if (options.priv) - this._importPrivate(options.priv, options.privEnc); - if (options.pub) - this._importPublic(options.pub, options.pubEnc); -} -module.exports = KeyPair; + if (cb === null) { + return this.emit('error', new ERR_MULTIPLE_CALLBACK()); + } -KeyPair.fromPublic = function fromPublic(ec, pub, enc) { - if (pub instanceof KeyPair) - return pub; + 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; - return new KeyPair(ec, { - pub: pub, - pubEnc: enc - }); -}; + if (rs.needReadable || rs.length < rs.highWaterMark) { + this._read(rs.highWaterMark); + } +} -KeyPair.fromPrivate = function fromPrivate(ec, priv, enc) { - if (priv instanceof KeyPair) - return priv; +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. - return new KeyPair(ec, { - priv: priv, - privEnc: enc - }); -}; + this._readableState.sync = false; -KeyPair.prototype.validate = function validate() { - var pub = this.getPublic(); + 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. - if (pub.isInfinity()) - return { result: false, reason: 'Invalid public key' }; - if (!pub.validate()) - return { result: false, reason: 'Public key is not a point' }; - if (!pub.mul(this.ec.curve.n).isInfinity()) - return { result: false, reason: 'Public key * N != O' }; - return { result: true, reason: null }; -}; + this.on('prefinish', prefinish); +} -KeyPair.prototype.getPublic = function getPublic(compact, enc) { - // compact is optional argument - if (typeof compact === 'string') { - enc = compact; - compact = null; +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); } +} - if (!this.pub) - this.pub = this.ec.g.mul(this.priv); +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.

Logical Hebrew ?? +// +// Both "ISO" charsets use a completely identical set of code points, whereas +// "windows-1255" and "x-mac-hebrew" are two different proper supersets of +// these code points. windows-1255 defines additional characters in the range +// 0x80-0x9F as some misc punctuation marks as well as some Hebrew-specific +// diacritics and additional 'Yiddish' ligature letters in the range 0xc0-0xd6. +// x-mac-hebrew defines similar additional code points but with a different +// mapping. +// +// As far as an average Hebrew text with no diacritics is concerned, all four +// charsets are identical with respect to code points. Meaning that for the +// main Hebrew alphabet, all four map the same values to all 27 Hebrew letters +// (including final letters). +// +// The dominant difference between these charsets is their directionality. +// "Visual" directionality means that the text is ordered as if the renderer is +// not aware of a BIDI rendering algorithm. The renderer sees the text and +// draws it from left to right. The text itself when ordered naturally is read +// backwards. A buffer of Visual Hebrew generally looks like so: +// "[last word of first line spelled backwards] [whole line ordered backwards +// and spelled backwards] [first word of first line spelled backwards] +// [end of line] [last word of second line] ... etc' " +// adding punctuation marks, numbers and English text to visual text is +// naturally also "visual" and from left to right. +// +// "Logical" directionality means the text is ordered "naturally" according to +// the order it is read. It is the responsibility of the renderer to display +// the text from right to left. A BIDI algorithm is used to place general +// punctuation marks, numbers and English text in the text. +// +// Texts in x-mac-hebrew are almost impossible to find on the Internet. From +// what little evidence I could find, it seems that its general directionality +// is Logical. +// +// To sum up all of the above, the Hebrew probing mechanism knows about two +// charsets: +// Visual Hebrew - "ISO-8859-8" - backwards text - Words and sentences are +// backwards while line order is natural. For charset recognition purposes +// the line order is unimportant (In fact, for this implementation, even +// word order is unimportant). +// Logical Hebrew - "windows-1255" - normal, naturally ordered text. +// +// "ISO-8859-8-I" is a subset of windows-1255 and doesn't need to be +// specifically identified. +// "x-mac-hebrew" is also identified as windows-1255. A text in x-mac-hebrew +// that contain special punctuation marks or diacritics is displayed with +// some unconverted characters showing as question marks. This problem might +// be corrected using another model prober for x-mac-hebrew. Due to the fact +// that x-mac-hebrew texts are so rare, writing another model prober isn't +// worth the effort and performance hit. +// +//////// The Prober //////// +// +// The prober is divided between two SBCharSetProbers and a HebrewProber, +// all of which are managed, created, fed data, inquired and deleted by the +// SBCSGroupProber. The two SBCharSetProbers identify that the text is in +// fact some kind of Hebrew, Logical or Visual. The final decision about which +// one is it is made by the HebrewProber by combining final-letter scores +// with the scores of the two SBCharSetProbers to produce a final answer. +// +// The SBCSGroupProber is responsible for stripping the original text of HTML +// tags, English characters, numbers, low-ASCII punctuation characters, spaces +// and new lines. It reduces any sequence of such characters to a single space. +// The buffer fed to each prober in the SBCS group prober is pure text in +// high-ASCII. +// The two SBCharSetProbers (model probers) share the same language model: +// Win1255Model. +// The first SBCharSetProber uses the model normally as any other +// SBCharSetProber does, to recognize windows-1255, upon which this model was +// built. The second SBCharSetProber is told to make the pair-of-letter +// lookup in the language model backwards. This in practice exactly simulates +// a visual Hebrew model using the windows-1255 logical Hebrew model. +// +// The HebrewProber is not using any language model. All it does is look for +// final-letter evidence suggesting the text is either logical Hebrew or visual +// Hebrew. Disjointed from the model probers, the results of the HebrewProber +// alone are meaningless. HebrewProber always returns 0.00 as confidence +// since it never identifies a charset by itself. Instead, the pointer to the +// HebrewProber is passed to the model probers as a helper "Name Prober". +// When the Group prober receives a positive identification from any prober, +// it asks for the name of the charset identified. If the prober queried is a +// Hebrew model prober, the model prober forwards the call to the +// HebrewProber to make the final decision. In the HebrewProber, the +// decision is made according to the final-letters scores maintained and Both +// model probers scores.

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.

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'; +/** + * Simple query string parser. + * + * @param {String} query The query string that needs to be parsed. + * @returns {Object} + * @api public + */ +function querystring(query) { + var parser = /([^=?#&]+)=?([^&]*)/g + , result = {} + , part; -module.exports = Transform; + while (part = parser.exec(query)) { + var key = decode(part[1]) + , value = decode(part[2]); -var Duplex = require('./_stream_duplex'); + // + // Prevent overriding of existing properties.
