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. module.exports = Transform; var Duplex = require('_stream_duplex'); var util = require('util'); util.inherits(Transform, Duplex); function TransformState(options, stream) { this.afterTransform = function(er, data) { return afterTransform(stream, er, data); }; this.needTransform = false; this.transforming = false; this.writecb = null; this.writechunk = null; } function afterTransform(stream, er, data) { var ts = stream._transformState; ts.transforming = false; var cb = ts.writecb; if (!cb) return stream.emit('error', new Error('no writecb in Transform class')); ts.writechunk = null; ts.writecb = null; if (data !== null && data !== undefined) stream.push(data); if (cb) cb(er); var rs = stream._readableState; rs.reading = false; if (rs.needReadable || rs.length < rs.highWaterMark) { stream._read(rs.highWaterMark); } } function Transform(options) { if (!(this instanceof Transform)) return new Transform(options); Duplex.call(this, options); var ts = this._transformState = new TransformState(options, this); // when the writable side finishes, then flush out anything remaining. var stream = this; // 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; this.once('finish', function() { if ('function' === typeof this._flush) this._flush(function(er) { done(stream, er); }); else done(stream); }); } 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.

A reminder on how two's complement actually * works. The first bit is the signed bit, i.e. tells us whether or not the * number should be positive or negative. If the two's complement value is * positive, then we're done, as it's equivalent to the unsigned representation. * * Now if the number is positive, you're pretty much done, you can just leverage * the unsigned translations and return those. Unfortunately, negative numbers * aren't quite that straightforward. * * At first glance, one might be inclined to use the traditional formula to * translate binary numbers between the positive and negative values in two's * complement. (Though it doesn't quite work for the most negative value) * Mainly: * - invert all the bits * - add one to the result * * Of course, this doesn't quite work in Javascript. Take for example the value * of -128. This could be represented in 16 bits (big-endian) as 0xff80. But of * course, Javascript will do the following: * * > ~0xff80 * -65409 * * Whoh there, Javascript, that's not quite right. But wait, according to * Javascript that's perfectly correct. When Javascript ends up seeing the * constant 0xff80, it has no notion that it is actually a signed number. It * assumes that we've input the unsigned value 0xff80. Thus, when it does the * binary negation, it casts it into a signed value, (positive 0xff80). Then * when you perform binary negation on that, it turns it into a negative number. * * Instead, we're going to have to use the following general formula, that works * in a rather Javascript friendly way.

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. module.exports = Transform; var Duplex = require('_stream_duplex'); var util = require('util'); util.inherits(Transform, Duplex); function TransformState(options, stream) { this.afterTransform = function(er, data) { return afterTransform(stream, er, data); }; this.needTransform = false; this.transforming = false; this.writecb = null; this.writechunk = null; } function afterTransform(stream, er, data) { var ts = stream._transformState; ts.transforming = false; var cb = ts.writecb; if (!cb) return stream.emit('error', new Error('no writecb in Transform class')); ts.writechunk = null; ts.writecb = null; if (data !== null && data !== undefined) stream.push(data); if (cb) cb(er); var rs = stream._readableState; rs.reading = false; if (rs.needReadable || rs.length < rs.highWaterMark) { stream._read(rs.highWaterMark); } } function Transform(options) { if (!(this instanceof Transform)) return new Transform(options); Duplex.call(this, options); var ts = this._transformState = new TransformState(options, this); // when the writable side finishes, then flush out anything remaining. var stream = this; // 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; this.once('finish', function() { if ('function' === typeof this._flush) this._flush(function(er) { done(stream, er); }); else done(stream); }); } 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.

A reminder on how two's complement actually * works. The first bit is the signed bit, i.e. tells us whether or not the * number should be positive or negative. If the two's complement value is * positive, then we're done, as it's equivalent to the unsigned representation. * * Now if the number is positive, you're pretty much done, you can just leverage * the unsigned translations and return those. Unfortunately, negative numbers * aren't quite that straightforward. * * At first glance, one might be inclined to use the traditional formula to * translate binary numbers between the positive and negative values in two's * complement. (Though it doesn't quite work for the most negative value) * Mainly: * - invert all the bits * - add one to the result * * Of course, this doesn't quite work in Javascript. Take for example the value * of -128. This could be represented in 16 bits (big-endian) as 0xff80. But of * course, Javascript will do the following: * * > ~0xff80 * -65409 * * Whoh there, Javascript, that's not quite right. But wait, according to * Javascript that's perfectly correct. When Javascript ends up seeing the * constant 0xff80, it has no notion that it is actually a signed number. It * assumes that we've input the unsigned value 0xff80. Thus, when it does the * binary negation, it casts it into a signed value, (positive 0xff80). Then * when you perform binary negation on that, it turns it into a negative number. * * Instead, we're going to have to use the following general formula, that works * in a rather Javascript friendly way.

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. module.exports = Transform; var Duplex = require('_stream_duplex'); var util = require('util'); util.inherits(Transform, Duplex); function TransformState(options, stream) { this.afterTransform = function(er, data) { return afterTransform(stream, er, data); }; this.needTransform = false; this.transforming = false; this.writecb = null; this.writechunk = null; } function afterTransform(stream, er, data) { var ts = stream._transformState; ts.transforming = false; var cb = ts.writecb; if (!cb) return stream.emit('error', new Error('no writecb in Transform class')); ts.writechunk = null; ts.writecb = null; if (data !== null && data !== undefined) stream.push(data); if (cb) cb(er); var rs = stream._readableState; rs.reading = false; if (rs.needReadable || rs.length < rs.highWaterMark) { stream._read(rs.highWaterMark); } } function Transform(options) { if (!(this instanceof Transform)) return new Transform(options); Duplex.call(this, options); var ts = this._transformState = new TransformState(options, this); // when the writable side finishes, then flush out anything remaining. var stream = this; // 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; this.once('finish', function() { if ('function' === typeof this._flush) this._flush(function(er) { done(stream, er); }); else done(stream); }); } 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.

The server can // either (i) reject the client or (ii) allow the client to connect as an // unauthorized connection. // // The mode is controlled by two boolean variables. // // requestCert // If true the server requests a certificate from client connections. For // the common HTTPS case, users will want this to be false, which is what // it defaults to. // // rejectUnauthorized // If true clients whose certificates are invalid for any reason will not // be allowed to make connections. If false, they will simply be marked as // unauthorized but secure communication will continue. By default this is // true. // // // // Options: // - requestCert. Send verify request.

If the two's complement value is * positive, then we're done, as it's equivalent to the unsigned representation. * * Now if the number is positive, you're pretty much done, you can just leverage * the unsigned translations and return those. Unfortunately, negative numbers * aren't quite that straightforward. * * At first glance, one might be inclined to use the traditional formula to * translate binary numbers between the positive and negative values in two's * complement. (Though it doesn't quite work for the most negative value) * Mainly: * - invert all the bits * - add one to the result * * Of course, this doesn't quite work in Javascript. Take for example the value * of -128. This could be represented in 16 bits (big-endian) as 0xff80. But of * course, Javascript will do the following: * * > ~0xff80 * -65409 * * Whoh there, Javascript, that's not quite right. But wait, according to * Javascript that's perfectly correct. When Javascript ends up seeing the * constant 0xff80, it has no notion that it is actually a signed number. It * assumes that we've input the unsigned value 0xff80. Thus, when it does the * binary negation, it casts it into a signed value, (positive 0xff80). Then * when you perform binary negation on that, it turns it into a negative number. * * Instead, we're going to have to use the following general formula, that works * in a rather Javascript friendly way.
