We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them. - -On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out. - - -## Maintainers - -- [Sindre Sorhus](https://github.com/sindresorhus) -- [Josh Junon](https://github.com/qix-) - - ---- - - diff --git a/reverse_engineering/node_modules/ansi-styles/index.d.ts b/reverse_engineering/node_modules/ansi-styles/index.d.ts deleted file mode 100644 index 44a907e..0000000 --- a/reverse_engineering/node_modules/ansi-styles/index.d.ts +++ /dev/null @@ -1,345 +0,0 @@ -declare type CSSColor = - | 'aliceblue' - | 'antiquewhite' - | 'aqua' - | 'aquamarine' - | 'azure' - | 'beige' - | 'bisque' - | 'black' - | 'blanchedalmond' - | 'blue' - | 'blueviolet' - | 'brown' - | 'burlywood' - | 'cadetblue' - | 'chartreuse' - | 'chocolate' - | 'coral' - | 'cornflowerblue' - | 'cornsilk' - | 'crimson' - | 'cyan' - | 'darkblue' - | 'darkcyan' - | 'darkgoldenrod' - | 'darkgray' - | 'darkgreen' - | 'darkgrey' - | 'darkkhaki' - | 'darkmagenta' - | 'darkolivegreen' - | 'darkorange' - | 'darkorchid' - | 'darkred' - | 'darksalmon' - | 'darkseagreen' - | 'darkslateblue' - | 'darkslategray' - | 'darkslategrey' - | 'darkturquoise' - | 'darkviolet' - | 'deeppink' - | 'deepskyblue' - | 'dimgray' - | 'dimgrey' - | 'dodgerblue' - | 'firebrick' - | 'floralwhite' - | 'forestgreen' - | 'fuchsia' - | 'gainsboro' - | 'ghostwhite' - | 'gold' - | 'goldenrod' - | 'gray' - | 'green' - | 'greenyellow' - | 'grey' - | 'honeydew' - | 'hotpink' - | 'indianred' - | 'indigo' - | 'ivory' - | 'khaki' - | 'lavender' - | 'lavenderblush' - | 'lawngreen' - | 'lemonchiffon' - | 'lightblue' - | 'lightcoral' - | 'lightcyan' - | 'lightgoldenrodyellow' - | 'lightgray' - | 'lightgreen' - | 'lightgrey' - | 'lightpink' - | 'lightsalmon' - | 'lightseagreen' - | 'lightskyblue' - | 'lightslategray' - | 'lightslategrey' - | 'lightsteelblue' - | 'lightyellow' - | 'lime' - | 'limegreen' - | 'linen' - | 'magenta' - | 'maroon' - | 'mediumaquamarine' - | 'mediumblue' - | 'mediumorchid' - | 'mediumpurple' - | 'mediumseagreen' - | 'mediumslateblue' - | 'mediumspringgreen' - | 'mediumturquoise' - | 'mediumvioletred' - | 'midnightblue' - | 'mintcream' - | 'mistyrose' - | 'moccasin' - | 'navajowhite' - | 'navy' - | 'oldlace' - | 'olive' - | 'olivedrab' - | 'orange' - | 'orangered' - | 'orchid' - | 'palegoldenrod' - | 'palegreen' - | 'paleturquoise' - | 'palevioletred' - | 'papayawhip' - | 'peachpuff' - | 'peru' - | 'pink' - | 'plum' - | 'powderblue' - | 'purple' - | 'rebeccapurple' - | 'red' - | 'rosybrown' - | 'royalblue' - | 'saddlebrown' - | 'salmon' - | 'sandybrown' - | 'seagreen' - | 'seashell' - | 'sienna' - | 'silver' - | 'skyblue' - | 'slateblue' - | 'slategray' - | 'slategrey' - | 'snow' - | 'springgreen' - | 'steelblue' - | 'tan' - | 'teal' - | 'thistle' - | 'tomato' - | 'turquoise' - | 'violet' - | 'wheat' - | 'white' - | 'whitesmoke' - | 'yellow' - | 'yellowgreen';

Also works as a duplex stream so you can collect buffers from a stream that emits them and emit buffers to a stream that consumes them! - -The original buffers are kept intact and copies are only done as necessary. Any reads that require the use of a single original buffer will return a slice of that buffer only (which references the same memory as the original buffer). Reads that span buffers perform concatenation as required and return the results transparently. - -```js -const BufferList = require('bl') - -var bl = new BufferList() -bl.append(Buffer.from('abcd')) -bl.append(Buffer.from('efg')) -bl.append('hi') // bl will also accept & convert Strings -bl.append(Buffer.from('j')) -bl.append(Buffer.from([ 0x3, 0x4 ])) - -console.log(bl.length) // 12 - -console.log(bl.slice(0, 10).toString('ascii')) // 'abcdefghij' -console.log(bl.slice(3, 10).toString('ascii')) // 'defghij' -console.log(bl.slice(3, 6).toString('ascii')) // 'def' -console.log(bl.slice(3, 8).toString('ascii')) // 'defgh' -console.log(bl.slice(5, 10).toString('ascii')) // 'fghij' - -console.log(bl.indexOf('def')) // 3 -console.log(bl.indexOf('asdf')) // -1 - -// or just use toString! -console.log(bl.toString()) // 'abcdefghij\u0003\u0004' -console.log(bl.toString('ascii', 3, 8)) // 'defgh' -console.log(bl.toString('ascii', 5, 10)) // 'fghij' - -// other standard Buffer readables -console.log(bl.readUInt16BE(10)) // 0x0304 -console.log(bl.readUInt16LE(10)) // 0x0403 -``` - -Give it a callback in the constructor and use it just like **[concat-stream](https://github.com/maxogden/node-concat-stream)**: - -```js -const bl = require('bl') - , fs = require('fs') - -fs.createReadStream('README.md') - .pipe(bl(function (err, data) { // note 'new' isn't strictly required - // `data` is a complete Buffer object containing the full data - console.log(data.toString()) - })) -``` - -Note that when you use the *callback* method like this, the resulting `data` parameter is a concatenation of all `Buffer` objects in the list. If you want to avoid the overhead of this concatenation (in cases of extreme performance consciousness), then avoid the *callback* method and just listen to `'end'` instead, like a standard Stream. - -Or to fetch a URL using [hyperquest](https://github.com/substack/hyperquest) (should work with [request](http://github.com/mikeal/request) and even plain Node http too!): -```js -const hyperquest = require('hyperquest') - , bl = require('bl') - , url = 'https://raw.github.com/rvagg/bl/master/README.md' - -hyperquest(url).pipe(bl(function (err, data) { - console.log(data.toString()) -})) -``` - -Or, use it as a readable stream to recompose a list of Buffers to an output source: - -```js -const BufferList = require('bl') - , fs = require('fs') - -var bl = new BufferList() -bl.append(Buffer.from('abcd')) -bl.append(Buffer.from('efg')) -bl.append(Buffer.from('hi')) -bl.append(Buffer.from('j')) - -bl.pipe(fs.createWriteStream('gibberish.txt')) -``` - -## API - - * new BufferList([ callback ]) - * bl.length - * bl.append(buffer) - * bl.get(index) - * bl.indexOf(value[, byteOffset][, encoding]) - * bl.slice([ start[, end ] ]) - * bl.shallowSlice([ start[, end ] ]) - * bl.copy(dest, [ destStart, [ srcStart [, srcEnd ] ] ]) - * bl.duplicate() - * bl.consume(bytes) - * bl.toString([encoding, [ start, [ end ]]]) - * bl.readDoubleBE(), bl.readDoubleLE(), bl.readFloatBE(), bl.readFloatLE(), bl.readInt32BE(), bl.readInt32LE(), bl.readUInt32BE(), bl.readUInt32LE(), bl.readInt16BE(), bl.readInt16LE(), bl.readUInt16BE(), bl.readUInt16LE(), bl.readInt8(), bl.readUInt8() - * Streams - --------------------------------------------------------- - -### new BufferList([ callback | Buffer | Buffer array | BufferList | BufferList array | String ]) -The constructor takes an optional callback, if supplied, the callback will be called with an error argument followed by a reference to the **bl** instance, when `bl.end()` is called (i.e. from a piped stream). This is a convenient method of collecting the entire contents of a stream, particularly when the stream is *chunky*, such as a network stream. - -Normally, no arguments are required for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` object. - -`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with: - -```js -var bl = require('bl') -var myinstance = bl() - -// equivalent to: - -var BufferList = require('bl') -var myinstance = new BufferList() -``` - --------------------------------------------------------- - -### bl.length -Get the length of the list in bytes. This is the sum of the lengths of all of the buffers contained in the list, minus any initial offset for a semi-consumed buffer at the beginning. Should accurately represent the total number of bytes that can be read from the list. - --------------------------------------------------------- - -### bl.append(Buffer | Buffer array | BufferList | BufferList array | String) -`append(buffer)` adds an additional buffer or BufferList to the internal list. `this` is returned so it can be chained. - --------------------------------------------------------- - -### bl.get(index) -`get()` will return the byte at the specified index. - --------------------------------------------------------- - -### bl.indexOf(value[, byteOffset][, encoding]) -`get()` will return the byte at the specified index. -`indexOf()` method returns the first index at which a given element can be found in the BufferList, or -1 if it is not present. - --------------------------------------------------------- - -### bl.slice([ start, [ end ] ]) -`slice()` returns a new `Buffer` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively. - -If the requested range spans a single internal buffer then a slice of that buffer will be returned which shares the original memory range of that Buffer. If the range spans multiple buffers then copy operations will likely occur to give you a uniform Buffer. - --------------------------------------------------------- - -### bl.shallowSlice([ start, [ end ] ]) -`shallowSlice()` returns a new `BufferList` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively. - -No copies will be performed. All buffers in the result share memory with the original list. - --------------------------------------------------------- - -### bl.copy(dest, [ destStart, [ srcStart [, srcEnd ] ] ]) -`copy()` copies the content of the list in the `dest` buffer, starting from `destStart` and containing the bytes within the range specified with `srcStart` to `srcEnd`. `destStart`, `start` and `end` are optional and will default to the beginning of the `dest` buffer, and the beginning and end of the list respectively. - --------------------------------------------------------- - -### bl.duplicate() -`duplicate()` performs a **shallow-copy** of the list. The internal Buffers remains the same, so if you change the underlying Buffers, the change will be reflected in both the original and the duplicate. This method is needed if you want to call `consume()` or `pipe()` and still keep the original list.Example: - -```js -var bl = new BufferList() - -bl.append('hello') -bl.append(' world') -bl.append('\n') - -bl.duplicate().pipe(process.stdout, { end: false }) - -console.log(bl.toString()) -``` - --------------------------------------------------------- - -### bl.consume(bytes) -`consume()` will shift bytes *off the start of the list*. The number of bytes consumed don't need to line up with the sizes of the internal Buffers—initial offsets will be calculated accordingly in order to give you a consistent view of the data. - --------------------------------------------------------- - -### bl.toString([encoding, [ start, [ end ]]]) -`toString()` will return a string representation of the buffer. The optional `start` and `end` arguments are passed on to `slice()`, while the `encoding` is passed on to `toString()` of the resulting Buffer. See the [Buffer#toString()](http://nodejs.org/docs/latest/api/buffer.html#buffer_buf_tostring_encoding_start_end) documentation for more information. - --------------------------------------------------------- - -### bl.readDoubleBE(), bl.readDoubleLE(), bl.readFloatBE(), bl.readFloatLE(), bl.readInt32BE(), bl.readInt32LE(), bl.readUInt32BE(), bl.readUInt32LE(), bl.readInt16BE(), bl.readInt16LE(), bl.readUInt16BE(), bl.readUInt16LE(), bl.readInt8(), bl.readUInt8() - -All of the standard byte-reading methods of the `Buffer` interface are implemented and will operate across internal Buffer boundaries transparently. - -See the [Buffer](http://nodejs.org/docs/latest/api/buffer.html) documentation for how these work. - --------------------------------------------------------- - -### Streams -**bl** is a Node **[Duplex Stream](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_duplex)**, so it can be read from and written to like a standard Node stream.

-## FAQ - -#### Why does `undefined` get converted to `null`? - -The `undefined` BSON type has been [deprecated for many years](http://bsonspec.org/spec.html), so this library has dropped support for it. Use the `ignoreUndefined` option (for example, from the [driver](http://mongodb.github.io/node-mongodb-native/2.2/api/MongoClient.html#connect) ) to instead remove `undefined` keys. - -#### How do I add custom serialization logic? - -This library looks for `toBSON()` functions on every path, and calls the `toBSON()` function to get the value to serialize. - -```javascript -var bson = new BSON(); - -class CustomSerialize { - toBSON() { - return 42; - } -} - -const obj = { answer: new CustomSerialize() }; -// "{ answer: 42 }" -console.log(bson.deserialize(bson.serialize(obj))); -``` diff --git a/reverse_engineering/node_modules/bson/bower.json b/reverse_engineering/node_modules/bson/bower.json deleted file mode 100644 index eded1f8..0000000 --- a/reverse_engineering/node_modules/bson/bower.json +++ /dev/null @@ -1,26 +0,0 @@ -{ - "name": "bson", - "description": "A bson parser for node.js and the browser", - "keywords": [ - "mongodb", - "bson", - "parser" - ], - "author": "Christian Amor Kvalheim ", - "main": "./browser_build/bson.js", - "license": "Apache-2.0", - "moduleType": [ - "globals", - "node" - ], - "ignore": [ - "**/.*", - "alternate_parsers", - "benchmarks", - "bower_components", - "node_modules", - "test", - "tools" - ], - "version": "1.1.6" -} diff --git a/reverse_engineering/node_modules/bson/browser_build/bson.js b/reverse_engineering/node_modules/bson/browser_build/bson.js deleted file mode 100644 index 9540a86..0000000 --- a/reverse_engineering/node_modules/bson/browser_build/bson.js +++ /dev/null @@ -1,18218 +0,0 @@ -(function webpackUniversalModuleDefinition(root, factory) { - if(typeof exports === 'object' && typeof module === 'object') - module.exports = factory();

Read the -[official docs](https://nodejs.org/api/buffer.html) for the full list of properties, -instance methods, and class methods that are supported. - -As mentioned above, `require('buffer')` or use the `Buffer` global with -[browserify](http://browserify.org) and this module will automatically be included -in your bundle. Almost any npm module will work in the browser, even if it assumes that -the node `Buffer` API will be available. - -To depend on this module explicitly (without browserify), require it like this: - -```js -var Buffer = require('buffer/').Buffer // note: the trailing slash is important! -``` - -To require this module explicitly, use `require('buffer/')` which tells the node.js module -lookup algorithm (also used by browserify) to use the **npm module** named `buffer` -instead of the **node.js core** module named `buffer`! - - -## how does it work? - -The Buffer constructor returns instances of `Uint8Array` that have their prototype -changed to `Buffer.prototype`. Furthermore, `Buffer` is a subclass of `Uint8Array`, -so the returned instances will have all the node `Buffer` methods and the -`Uint8Array` methods. Square bracket notation works as expected -- it returns a -single octet. - -The `Uint8Array` prototype remains unmodified. - - -## tracking the latest node api - -This module tracks the Buffer API in the latest (unstable) version of node.js. The Buffer -API is considered **stable** in the -[node stability index](https://nodejs.org/docs/latest/api/documentation.html#documentation_stability_index), -so it is unlikely that there will ever be breaking changes. -Nonetheless, when/if the Buffer API changes in node, this module's API will change -accordingly. - -## related packages - -- [`buffer-reverse`](https://www.npmjs.com/package/buffer-reverse) - Reverse a buffer -- [`buffer-xor`](https://www.npmjs.com/package/buffer-xor) - Bitwise xor a buffer -- [`is-buffer`](https://www.npmjs.com/package/is-buffer) - Determine if an object is a Buffer without including the whole `Buffer` package - -## conversion packages - -### convert typed array to buffer - -Use [`typedarray-to-buffer`](https://www.npmjs.com/package/typedarray-to-buffer) to convert any kind of typed array to a `Buffer`. Does not perform a copy, so it's super fast. - -### convert buffer to typed array - -`Buffer` is a subclass of `Uint8Array` (which is a typed array). So there is no need to explicitly convert to typed array. Just use the buffer as a `Uint8Array`. - -### convert blob to buffer - -Use [`blob-to-buffer`](https://www.npmjs.com/package/blob-to-buffer) to convert a `Blob` to a `Buffer`. - -### convert buffer to blob - -To convert a `Buffer` to a `Blob`, use the `Blob` constructor: - -```js -var blob = new Blob([ buffer ]) -``` - -Optionally, specify a mimetype: - -```js -var blob = new Blob([ buffer ], { type: 'text/html' }) -``` - -### convert arraybuffer to buffer - -To convert an `ArrayBuffer` to a `Buffer`, use the `Buffer.from` function. Does not perform a copy, so it's super fast. - -```js -var buffer = Buffer.from(arrayBuffer) -``` - -### convert buffer to arraybuffer - -To convert a `Buffer` to an `ArrayBuffer`, use the `.buffer` property (which is present on all `Uint8Array` objects): - -```js -var arrayBuffer = buffer.buffer.slice( - buffer.byteOffset, buffer.byteOffset + buffer.byteLength -) -``` - -Alternatively, use the [`to-arraybuffer`](https://www.npmjs.com/package/to-arraybuffer) module. - -## performance - -See perf tests in `/perf`. - -`BrowserBuffer` is the browser `buffer` module (this repo). `Uint8Array` is included as a -sanity check (since `BrowserBuffer` uses `Uint8Array` under the hood, `Uint8Array` will -always be at least a bit faster). Finally, `NodeBuffer` is the node.js buffer module, -which is included to compare against. - -NOTE: Performance has improved since these benchmarks were taken.

npm run test-browser-es6-local # For ES6 compliant browsers - -This will print out a URL that you can then open in a browser to run the tests, using [airtap](https://www.npmjs.com/package/airtap). - -To run automated browser tests using Saucelabs, ensure that your `SAUCE_USERNAME` and `SAUCE_ACCESS_KEY` environment variables are set, then run: - - npm test - -This is what's run in Travis, to check against various browsers. The list of browsers is kept in the `bin/airtap-es5.yml` and `bin/airtap-es6.yml` files. - -## JavaScript Standard Style - -This module uses [JavaScript Standard Style](https://github.com/feross/standard). - -[![JavaScript Style Guide](https://cdn.rawgit.com/feross/standard/master/badge.svg)](https://github.com/feross/standard) - -To test that the code conforms to the style, `npm install` and run: - - ./node_modules/.bin/standard - -## credit - -This was originally forked from [buffer-browserify](https://github.com/toots/buffer-browserify). - -## Security Policies and Procedures - -The `buffer` team and community take all security bugs in `buffer` seriously.

By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function. - -All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha). - -```js -var convert = require('color-convert'); - -// Hex to LAB -convert.hex.lab('DEADBF'); // [ 76, 21, -2 ] -convert.hex.lab.raw('DEADBF'); // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ] - -// RGB to CMYK -convert.rgb.cmyk(167, 255, 4); // [ 35, 0, 98, 0 ] -convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ] -``` - -### Arrays -All functions that accept multiple arguments also support passing an array. - -Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.) - -```js -var convert = require('color-convert'); - -convert.rgb.hex(123, 45, 67); // '7B2D43' -convert.rgb.hex([123, 45, 67]); // '7B2D43' -``` - -## Routing - -Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex). - -Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete.

This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. - -Example _app.js_: - -```js -var debug = require('debug')('http') - , http = require('http') - , name = 'My App'; - -// fake app - -debug('booting %s', name); - -http.createServer(function(req, res){ - debug(req.method + ' ' + req.url); - res.end('hello\n'); -}).listen(3000, function(){ - debug('listening'); -}); - -// fake worker of some kind - -require('./worker'); -``` - -Example _worker.js_: - -```js -var debug = require('debug')('worker'); - -setInterval(function(){ - debug('doing some work'); -}, 1000); -``` - - The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples: - - ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png) - - ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png) - -#### Windows note - - On Windows the environment variable is set using the `set` command. - - ```cmd - set DEBUG=*,-not_this - ``` - - Note that PowerShell uses different syntax to set environment variables. - - ```cmd - $env:DEBUG = "*,-not_this" - ``` - -Then, run the program to be debugged as usual. - -## Millisecond diff - - When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. - - ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png) - - When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below: - - ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png) - -## Conventions - - If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". - -## Wildcards - - The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. - - You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:". - -## Environment Variables - - When running through Node.js, you can set a few environment variables that will - change the behavior of the debug logging: - -| Name | Purpose | -|-----------|-------------------------------------------------| -| `DEBUG` | Enables/disables specific debugging namespaces. | -| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | -| `DEBUG_DEPTH` | Object inspection depth. | -| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | - - - __Note:__ The environment variables beginning with `DEBUG_` end up being - converted into an Options object that gets used with `%o`/`%O` formatters. - See the Node.js documentation for - [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) - for the complete list. - -## Formatters - - - Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters: - -| Formatter | Representation | -|-----------|----------------| -| `%O` | Pretty-print an Object on multiple lines. | -| `%o` | Pretty-print an Object all on a single line. | -| `%s` | String. | -| `%d` | Number (both integer and float). | -| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | -| `%%` | Single percent sign ('%'). This does not consume an argument. | - -### Custom formatters - - You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like: - -```js -const createDebug = require('debug') -createDebug.formatters.h = (v) => { - return v.toString('hex') -} - -// …elsewhere -const debug = createDebug('foo') -debug('this is hex: %h', new Buffer('hello world')) -// foo this is hex: 68656c6c6f20776f726c6421 +0ms -``` - -## Browser support - You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), - or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), - if you don't want to build it yourself. - - Debug's enable state is currently persisted by `localStorage`. - Consider the situation shown below where you have `worker:a` and `worker:b`, - and wish to debug both. You can enable this using `localStorage.debug`: - -```js -localStorage.debug = 'worker:*' -``` - -And then refresh the page. - -```js -a = debug('worker:a'); -b = debug('worker:b'); - -setInterval(function(){ - a('doing some work'); -}, 1000); - -setInterval(function(){ - b('doing some work'); -}, 1200); -``` - -#### Web Inspector Colors - - Colors are also enabled on "Web Inspectors" that understand the `%c` formatting - option. These are WebKit web inspectors, Firefox ([since version - 31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) - and the Firebug plugin for Firefox (any version). - - Colored output looks something like: - - ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png) - - -## Output streams - - By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: - -Example _stdout.js_: - -```js -var debug = require('debug'); -var error = debug('app:error'); - -// by default stderr is used -error('goes to stderr!'); - -var log = debug('app:log'); -// set this namespace to log via console.log -log.log = console.log.bind(console); // don't forget to bind to console! -log('goes to stdout'); -error('still goes to stderr!'); - -// set all output to go via console.info -// overrides all per-namespace log settings -debug.log = console.info.bind(console); -error('now goes to stdout via console.info'); -log('still goes to stdout, but via console.info now'); -``` - - -## Authors - - - TJ Holowaychuk - - Nathan Rajlich - - Andrew Rhyne - -## Backers - -Support us with a monthly donation and help us continue our activities.

This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. - -Example [_app.js_](./examples/node/app.js): - -```js -var debug = require('debug')('http') - , http = require('http') - , name = 'My App'; - -// fake app - -debug('booting %o', name); - -http.createServer(function(req, res){ - debug(req.method + ' ' + req.url); - res.end('hello\n'); -}).listen(3000, function(){ - debug('listening'); -}); - -// fake worker of some kind - -require('./worker'); -``` - -Example [_worker.js_](./examples/node/worker.js): - -```js -var a = require('debug')('worker:a') - , b = require('debug')('worker:b'); - -function work() { - a('doing lots of uninteresting work'); - setTimeout(work, Math.random() * 1000); -} - -work(); - -function workb() { - b('doing some work'); - setTimeout(workb, Math.random() * 2000); -} - -workb(); -``` - -The `DEBUG` environment variable is then used to enable these based on space or -comma-delimited names. - -Here are some examples: - -screen shot 2017-08-08 at 12 53 04 pm -screen shot 2017-08-08 at 12 53 38 pm -screen shot 2017-08-08 at 12 53 25 pm - -#### Windows command prompt notes - -##### CMD - -On Windows the environment variable is set using the `set` command. - -```cmd -set DEBUG=*,-not_this -``` - -Example: - -```cmd -set DEBUG=* & node app.js -``` - -##### PowerShell (VS Code default) - -PowerShell uses different syntax to set environment variables. - -```cmd -$env:DEBUG = "*,-not_this" -``` - -Example: - -```cmd -$env:DEBUG='app';node app.js -``` - -Then, run the program to be debugged as usual. - -npm script example: -```js - "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js", -``` - -## Namespace Colors - -Every debug instance has a color generated for it based on its namespace name. -This helps when visually parsing the debug output to identify which debug instance -a debug line belongs to. - -#### Node.js - -In Node.js, colors are enabled when stderr is a TTY. You also _should_ install -the [`supports-color`](https://npmjs.org/supports-color) module alongside debug, -otherwise debug will only use a small handful of basic colors. - - - -#### Web Browser - -Colors are also enabled on "Web Inspectors" that understand the `%c` formatting -option. These are WebKit web inspectors, Firefox ([since version -31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) -and the Firebug plugin for Firefox (any version). - - - - -## Millisecond diff - -When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. - - - -When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below: - - - - -## Conventions - -If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output. - -## Wildcards - -The `*` character may be used as a wildcard. Suppose for example your library has -debuggers named "connect:bodyParser", "connect:compress", "connect:session", -instead of listing all three with -`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do -`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. - -You can also exclude specific debuggers by prefixing them with a "-" character. -For example, `DEBUG=*,-connect:*` would include all debuggers except those -starting with "connect:". - -## Environment Variables - -When running through Node.js, you can set a few environment variables that will -change the behavior of the debug logging: - -| Name | Purpose | -|-----------|-------------------------------------------------| -| `DEBUG` | Enables/disables specific debugging namespaces. | -| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). | -| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | -| `DEBUG_DEPTH` | Object inspection depth. | -| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | - - -__Note:__ The environment variables beginning with `DEBUG_` end up being -converted into an Options object that gets used with `%o`/`%O` formatters. -See the Node.js documentation for -[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) -for the complete list. - -## Formatters - -Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. -Below are the officially supported formatters: - -| Formatter | Representation | -|-----------|----------------| -| `%O` | Pretty-print an Object on multiple lines. | -| `%o` | Pretty-print an Object all on a single line. | -| `%s` | String. | -| `%d` | Number (both integer and float). | -| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | -| `%%` | Single percent sign ('%'). This does not consume an argument. | - - -### Custom formatters - -You can add custom formatters by extending the `debug.formatters` object. -For example, if you wanted to add support for rendering a Buffer as hex with -`%h`, you could do something like: - -```js -const createDebug = require('debug') -createDebug.formatters.h = (v) => { - return v.toString('hex') -} - -// …elsewhere -const debug = createDebug('foo') -debug('this is hex: %h', new Buffer('hello world')) -// foo this is hex: 68656c6c6f20776f726c6421 +0ms -``` - - -## Browser Support - -You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), -or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), -if you don't want to build it yourself. - -Debug's enable state is currently persisted by `localStorage`. -Consider the situation shown below where you have `worker:a` and `worker:b`, -and wish to debug both. You can enable this using `localStorage.debug`: - -```js -localStorage.debug = 'worker:*' -``` - -And then refresh the page. - -```js -a = debug('worker:a'); -b = debug('worker:b'); - -setInterval(function(){ - a('doing some work'); -}, 1000); - -setInterval(function(){ - b('doing some work'); -}, 1200); -``` - - -## Output streams - - By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: - -Example [_stdout.js_](./examples/node/stdout.js): - -```js -var debug = require('debug'); -var error = debug('app:error'); - -// by default stderr is used -error('goes to stderr!'); - -var log = debug('app:log'); -// set this namespace to log via console.log -log.log = console.log.bind(console); // don't forget to bind to console! -log('goes to stdout'); -error('still goes to stderr!'); - -// set all output to go via console.info -// overrides all per-namespace log settings -debug.log = console.info.bind(console); -error('now goes to stdout via console.info'); -log('still goes to stdout, but via console.info now'); -``` - -## Extend -You can simply extend debugger -```js -const log = require('debug')('auth'); - -//creates new debug instance with extended namespace -const logSign = log.extend('sign'); -const logLogin = log.extend('login'); - -log('hello'); // auth hello -logSign('hello'); //auth:sign hello -logLogin('hello'); //auth:login hello -``` - -## Set dynamically - -You can also enable debug dynamically by calling the `enable()` method : - -```js -let debug = require('debug'); - -console.log(1, debug.enabled('test')); - -debug.enable('test'); -console.log(2, debug.enabled('test')); - -debug.disable(); -console.log(3, debug.enabled('test')); - -``` - -print : -``` -1 false -2 true -3 false -``` - -Usage : -`enable(namespaces)` -`namespaces` can include modes separated by a colon and wildcards. - -Note that calling `enable()` completely overrides previously set DEBUG variable : - -``` -$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))' -=> false -``` - -`disable()` - -Will disable all namespaces. The functions returns the namespaces currently -enabled (and skipped). This can be useful if you want to disable debugging -temporarily without knowing what was enabled to begin with. - -For example: - -```js -let debug = require('debug'); -debug.enable('foo:*,-foo:bar'); -let namespaces = debug.disable(); -debug.enable(namespaces); -``` - -Note: There is no guarantee that the string will be identical to the initial -enable string, but semantically they will be identical. - -## Checking whether a debug target is enabled - -After you've created a debug instance, you can determine whether or not it is -enabled by checking the `enabled` property: - -```javascript -const debug = require('debug')('http'); - -if (debug.enabled) { - // do stuff... -} -``` - -You can also manually toggle this property to force the debug instance to be -enabled or disabled. - - -## Authors - - - TJ Holowaychuk - - Nathan Rajlich - - Andrew Rhyne - -## Backers - -Support us with a monthly donation and help us continue our activities.

You can find a list of changes [here](CHANGES_3.0.0.md).** - -## Version 4.0 - -**Looking for the latest?** We're working on the next major version of the driver, now in beta. -Check out our [beta version 4.0 here](https://github.com/mongodb/node-mongodb-native/tree/4.0), which includes a full migration of the driver to TypeScript. - -## Quick Links - -| what | where | -| ------------- | ---------------------------------------------------- | -| documentation | https://mongodb.github.io/node-mongodb-native | -| api-doc | https://mongodb.github.io/node-mongodb-native/3.6/api | -| source | https://github.com/mongodb/node-mongodb-native | -| mongodb | https://www.mongodb.org | - -### Bugs / Feature Requests - -Think you’ve found a bug? Want to see a new feature in `node-mongodb-native`? Please open a -case in our issue management tool, JIRA: - -- Create an account and login [jira.mongodb.org](https://jira.mongodb.org). -- Navigate to the NODE project [jira.mongodb.org/browse/NODE](https://jira.mongodb.org/browse/NODE). -- Click **Create Issue** - Please provide as much information as possible about the issue type and how to reproduce it. - -Bug reports in JIRA for all driver projects (i.e. NODE, PYTHON, CSHARP, JAVA) and the -Core Server (i.e. SERVER) project are **public**. - -### Support / Feedback - -For issues with, questions about, or feedback for the Node.js driver, please look into our [support channels](https://docs.mongodb.com/manual/support). Please do not email any of the driver developers directly with issues or questions - you're more likely to get an answer on the [MongoDB Community Forums](https://community.mongodb.com/tags/c/drivers-odms-connectors/7/node-js-driver). - -### Change Log - -Change history can be found in [`HISTORY.md`](HISTORY.md). - -### Compatibility - -For version compatibility matrices, please refer to the following links: - -- [MongoDB](https://docs.mongodb.com/ecosystem/drivers/driver-compatibility-reference/#reference-compatibility-mongodb-node) -- [NodeJS](https://docs.mongodb.com/ecosystem/drivers/driver-compatibility-reference/#reference-compatibility-language-node) - -## Installation - -The recommended way to get started using the Node.js driver is by using `npm` (Node Package Manager) to install the dependency in your project. - -## MongoDB Driver - -Given that you have created your own project using `npm init` we install the MongoDB driver and its dependencies by executing the following `npm` command. - -```bash -npm install mongodb --save -``` - -This will download the MongoDB driver and add a dependency entry in your `package.json` file. - -You can also use the [Yarn](https://yarnpkg.com/en) package manager. - -## Troubleshooting - -The MongoDB driver depends on several other packages. These are: - -- [bson](https://github.com/mongodb/js-bson) -- [bson-ext](https://github.com/mongodb-js/bson-ext) -- [kerberos](https://github.com/mongodb-js/kerberos) -- [mongodb-client-encryption](https://github.com/mongodb/libmongocrypt#readme) - -The `kerberos` package is a C++ extension that requires a build environment to be installed on your system. You must be able to build Node.js itself in order to compile and install the `kerberos` module. Furthermore, the `kerberos` module requires the MIT Kerberos package to correctly compile on UNIX operating systems. Consult your UNIX operation system package manager for what libraries to install. - -**Windows already contains the SSPI API used for Kerberos authentication. However, you will need to install a full compiler tool chain using Visual Studio C++ to correctly install the Kerberos extension.** - -### Diagnosing on UNIX - -If you don’t have the build-essentials, this module won’t build. In the case of Linux, you will need gcc, g++, Node.js with all the headers and Python. The easiest way to figure out what’s missing is by trying to build the Kerberos project. You can do this by performing the following steps. - -```bash -git clone https://github.com/mongodb-js/kerberos -cd kerberos -npm install -``` - -If all the steps complete, you have the right toolchain installed. If you get the error "node-gyp not found," you need to install `node-gyp` globally: - -```bash -npm install -g node-gyp -``` - -If it correctly compiles and runs the tests you are golden. We can now try to install the `mongod` driver by performing the following command. - -```bash -cd yourproject -npm install mongodb --save -``` - -If it still fails the next step is to examine the npm log. Rerun the command but in this case in verbose mode. - -```bash -npm --loglevel verbose install mongodb -``` - -This will print out all the steps npm is performing while trying to install the module. - -### Diagnosing on Windows - -A compiler tool chain known to work for compiling `kerberos` on Windows is the following. - -- Visual Studio C++ 2010 (do not use higher versions) -- Windows 7 64bit SDK -- Python 2.7 or higher - -Open the Visual Studio command prompt. Ensure `node.exe` is in your path and install `node-gyp`. - -```bash -npm install -g node-gyp -``` - -Next, you will have to build the project manually to test it. Clone the repo, install dependencies and rebuild: - -```bash -git clone https://github.com/christkv/kerberos.git -cd kerberos -npm install -node-gyp rebuild -``` - -This should rebuild the driver successfully if you have everything set up correctly. - -### Other possible issues - -Your Python installation might be hosed making gyp break. Test your deployment environment first by trying to build Node.js itself on the server in question, as this should unearth any issues with broken packages (and there are a lot of broken packages out there). - -Another tip is to ensure your user has write permission to wherever the Node.js modules are being installed. - -## Quick Start - -This guide will show you how to set up a simple application using Node.js and MongoDB. Its scope is only how to set up the driver and perform the simple CRUD operations. For more in-depth coverage, see the [tutorials](docs/reference/content/tutorials/main.md). - -### Create the `package.json` file - -First, create a directory where your application will live. - -```bash -mkdir myproject -cd myproject -``` - -Enter the following command and answer the questions to create the initial structure for your new project: - -```bash -npm init -``` - -Next, install the driver dependency. - -```bash -npm install mongodb --save -``` - -You should see **NPM** download a lot of files. Once it's done you'll find all the downloaded packages under the **node_modules** directory. - -### Start a MongoDB Server - -For complete MongoDB installation instructions, see [the manual](https://docs.mongodb.org/manual/installation/). - -1. Download the right MongoDB version from [MongoDB](https://www.mongodb.org/downloads) -2. Create a database directory (in this case under **/data**). -3. Install and start a `mongod` process. - -```bash -mongod --dbpath=/data -``` - -You should see the **mongod** process start up and print some status information. - -### Connect to MongoDB - -Create a new **app.js** file and add the following code to try out some basic CRUD -operations using the MongoDB driver. - -Add code to connect to the server and the database **myproject**: - -```js -const MongoClient = require('mongodb').MongoClient; -const assert = require('assert'); - -// Connection URL -const url = 'mongodb://localhost:27017'; - -// Database Name -const dbName = 'myproject'; -const client = new MongoClient(url); -// Use connect method to connect to the server -client.connect(function(err) { - assert.equal(null, err); - console.log('Connected successfully to server'); - - const db = client.db(dbName); - - client.close(); -}); -``` - -Run your app from the command line with: - -```bash -node app.js -``` - -The application should print **Connected successfully to server** to the console. - -### Insert a Document - -Add to **app.js** the following function which uses the **insertMany** -method to add three documents to the **documents** collection. - -```js -const insertDocuments = function(db, callback) { - // Get the documents collection - const collection = db.collection('documents'); - // Insert some documents - collection.insertMany([{ a: 1 }, { a: 2 }, { a: 3 }], function(err, result) { - assert.equal(err, null); - assert.equal(3, result.result.n); - assert.equal(3, result.ops.length); - console.log('Inserted 3 documents into the collection'); - callback(result); - }); -}; -``` - -The **insert** command returns an object with the following fields: - -- **result** Contains the result document from MongoDB -- **ops** Contains the documents inserted with added **\_id** fields -- **connection** Contains the connection used to perform the insert - -Add the following code to call the **insertDocuments** function: - -```js -const MongoClient = require('mongodb').MongoClient; -const assert = require('assert'); - -// Connection URL -const url = 'mongodb://localhost:27017'; - -// Database Name -const dbName = 'myproject'; - -// Use connect method to connect to the server -MongoClient.connect(url, function(err, client) { - assert.equal(null, err); - console.log('Connected successfully to server'); - - const db = client.db(dbName); - - insertDocuments(db, function() { - client.close(); - }); -}); -``` - -Run the updated **app.js** file: - -```bash -node app.js -``` - -The operation returns the following output: - -```bash -Connected successfully to server -Inserted 3 documents into the collection -``` - -### Find All Documents - -Add a query that returns all the documents. - -```js -const findDocuments = function(db, callback) { - // Get the documents collection - const collection = db.collection('documents'); - // Find some documents - collection.find({}).toArray(function(err, docs) { - assert.equal(err, null); - console.log('Found the following records'); - console.log(docs); - callback(docs); - }); -}; -``` - -This query returns all the documents in the **documents** collection. Add the **findDocument** method to the **MongoClient.connect** callback: - -```js -const MongoClient = require('mongodb').MongoClient; -const assert = require('assert'); - -// Connection URL -const url = 'mongodb://localhost:27017'; - -// Database Name -const dbName = 'myproject'; - -// Use connect method to connect to the server -MongoClient.connect(url, function(err, client) { - assert.equal(null, err); - console.log('Connected correctly to server'); - - const db = client.db(dbName); - - insertDocuments(db, function() { - findDocuments(db, function() { - client.close(); - }); - }); -}); -``` - -### Find Documents with a Query Filter - -Add a query filter to find only documents which meet the query criteria. - -```js -const findDocuments = function(db, callback) { - // Get the documents collection - const collection = db.collection('documents'); - // Find some documents - collection.find({ a: 3 }).toArray(function(err, docs) { - assert.equal(err, null); - console.log('Found the following records'); - console.log(docs); - callback(docs); - }); -}; -``` - -Only the documents which match `'a' : 3` should be returned. - -### Update a document - -The following operation updates a document in the **documents** collection. - -```js -const updateDocument = function(db, callback) { - // Get the documents collection - const collection = db.collection('documents'); - // Update document where a is 2, set b equal to 1 - collection.updateOne({ a: 2 }, { $set: { b: 1 } }, function(err, result) { - assert.equal(err, null); - assert.equal(1, result.result.n); - console.log('Updated the document with the field a equal to 2'); - callback(result); - }); -}; -``` - -The method updates the first document where the field **a** is equal to **2** by adding a new field **b** to the document set to **1**. Next, update the callback function from **MongoClient.connect** to include the update method. - -```js -const MongoClient = require('mongodb').MongoClient; -const assert = require('assert'); - -// Connection URL -const url = 'mongodb://localhost:27017'; - -// Database Name -const dbName = 'myproject'; - -// Use connect method to connect to the server -MongoClient.connect(url, function(err, client) { - assert.equal(null, err); - console.log('Connected successfully to server'); - - const db = client.db(dbName); - - insertDocuments(db, function() { - updateDocument(db, function() { - client.close(); - }); - }); -}); -``` - -### Remove a document - -Remove the document where the field **a** is equal to **3**. - -```js -const removeDocument = function(db, callback) { - // Get the documents collection - const collection = db.collection('documents'); - // Delete document where a is 3 - collection.deleteOne({ a: 3 }, function(err, result) { - assert.equal(err, null); - assert.equal(1, result.result.n); - console.log('Removed the document with the field a equal to 3'); - callback(result); - }); -}; -``` - -Add the new method to the **MongoClient.connect** callback function. - -```js -const MongoClient = require('mongodb').MongoClient; -const assert = require('assert'); - -// Connection URL -const url = 'mongodb://localhost:27017'; - -// Database Name -const dbName = 'myproject'; - -// Use connect method to connect to the server -MongoClient.connect(url, function(err, client) { - assert.equal(null, err); - console.log('Connected successfully to server'); - - const db = client.db(dbName); - - insertDocuments(db, function() { - updateDocument(db, function() { - removeDocument(db, function() { - client.close(); - }); - }); - }); -}); -``` - -### Index a Collection - -[Indexes](https://docs.mongodb.org/manual/indexes/) can improve your application's -performance. The following function creates an index on the **a** field in the -**documents** collection. - -```js -const indexCollection = function(db, callback) { - db.collection('documents').createIndex({ a: 1 }, null, function(err, results) { - console.log(results); - callback(); - }); -}; -``` - -Add the `indexCollection` method to your app: - -```js -const MongoClient = require('mongodb').MongoClient; -const assert = require('assert'); - -// Connection URL -const url = 'mongodb://localhost:27017';

While you can pass in your `require` in `options`, if you want to create your own function that's bound to your `require`, you can do it with `makeOptionalRequire`: - -```ts -import { makeOptionalRequire } from "optional-require"; - -const optionalRequire = makeOptionalRequire(require); - -// now you can optional require files in same dir as your file -const myModule = optionalRequire("./my-module"); -``` - -### Legacy Usage - -In older versions, this module exports `makeOptionalRequire` directly and this is the legacy usage in JavaScript, which is still supported: - -```js -const optionalRequire = require("optional-require")(require); - -const foo = optionalRequire("foo") || {}; -const bar = optionalRequire("bar", true); // true enables console.log a message when not found -const xyz = optionalRequire("xyz", "test"); // "test" enables console.log a message with "test" added. -const fbPath = optionalRequire.resolve("foo", "foo doesn't exist"); -const rel = optionalRequire("../foo/bar"); // relative module path works -``` - -## API - - - -# LICENSE - -Apache-2.0 © [Joel Chen](https://github.com/jchip) - -[travis-image]: https://travis-ci.org/jchip/optional-require.svg?branch=master -[travis-url]: https://travis-ci.org/jchip/optional-require -[npm-image]: https://badge.fury.io/js/optional-require.svg -[npm-url]: https://npmjs.org/package/optional-require -[daviddm-image]: https://david-dm.org/jchip/optional-require/status.svg -[daviddm-url]: https://david-dm.org/jchip/optional-require -[daviddm-dev-image]: https://david-dm.org/jchip/optional-require/dev-status.svg -[daviddm-dev-url]: https://david-dm.org/jchip/optional-require?type=dev diff --git a/reverse_engineering/node_modules/optional-require/dist/index.d.ts b/reverse_engineering/node_modules/optional-require/dist/index.d.ts deleted file mode 100644 index f6bae60..0000000 --- a/reverse_engineering/node_modules/optional-require/dist/index.d.ts +++ /dev/null @@ -1,138 +0,0 @@ -/// -/** - * function to log in case require module was not found - * - * @params message - message to log - * @params path - path of the module that user tried to require - */ -export declare type LogFunction = (message: string, path: string) => void; -/** - * Options for calling optionalRequire - */ -export declare type OptionalRequireOpts = { - /** - * `notFound` is a function.

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 Duplex = require('./_stream_duplex'); - -/**/ -var util = Object.create(require('core-util-is')); -util.inherits = require('inherits'); -/**/ - -util.inherits(Transform, Duplex); - -function afterTransform(er, data) { - var ts = this._transformState; - ts.transforming = false; - - var cb = ts.writecb; - - if (!cb) { - return this.emit('error', new Error('write callback called multiple times')); - } - - 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._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.

It's surprisingly common to forget to check the type of your variables in a -dynamically-typed language like JavaScript. - -Usually the consequences of assuming the wrong type is that your program crashes with an -uncaught exception. But the failure mode for forgetting to check the type of arguments to -the `Buffer` constructor is more catastrophic. - -Here's an example of a vulnerable service that takes a JSON payload and converts it to -hex: - -```js -// Take a JSON payload {str: "some string"} and convert it to hex -var server = http.createServer(function (req, res) { - var data = '' - req.setEncoding('utf8') - req.on('data', function (chunk) { - data += chunk - }) - req.on('end', function () { - var body = JSON.parse(data) - res.end(new Buffer(body.str).toString('hex')) - }) -}) - -server.listen(8080) -``` - -In this example, an http client just has to send: - -```json -{ - "str": 1000 -} -``` - -and it will get back 1,000 bytes of uninitialized memory from the server. - -This is a very serious bug. It's similar in severity to the -[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process -memory by remote attackers. - - -### Which real-world packages were vulnerable? - -#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht) - -[Mathias Buus](https://github.com/mafintosh) and I -([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages, -[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow -anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get -them to reveal 20 bytes at a time of uninitialized memory from the node.js process. - -Here's -[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8) -that fixed it. We released a new fixed version, created a -[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all -vulnerable versions on npm so users will get a warning to upgrade to a newer version. - -#### [`ws`](https://www.npmjs.com/package/ws) - -That got us wondering if there were other vulnerable packages. Sure enough, within a short -period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the -most popular WebSocket implementation in node.js. - -If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as -expected, then uninitialized server memory would be disclosed to the remote peer. - -These were the vulnerable methods: - -```js -socket.send(number) -socket.ping(number) -socket.pong(number) -``` - -Here's a vulnerable socket server with some echo functionality: - -```js -server.on('connection', function (socket) { - socket.on('message', function (message) { - message = JSON.parse(message) - if (message.type === 'echo') { - socket.send(message.data) // send back the user's message - } - }) -}) -``` - -`socket.send(number)` called on the server, will disclose server memory. - -Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue -was fixed, with a more detailed explanation. Props to -[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the -[Node Security Project disclosure](https://nodesecurity.io/advisories/67). - - -### What's the solution? - -It's important that node.js offers a fast way to get memory otherwise performance-critical -applications would needlessly get a lot slower. - -But we need a better way to *signal our intent* as programmers. **When we want -uninitialized memory, we should request it explicitly.** - -Sensitive functionality should not be packed into a developer-friendly API that loosely -accepts many different types. This type of API encourages the lazy practice of passing -variables in without checking the type very carefully. - -#### A new API: `Buffer.allocUnsafe(number)` - -The functionality of creating buffers with uninitialized memory should be part of another -API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that -frequently gets user input of all sorts of different types passed into it. - -```js -var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory! - -// Immediately overwrite the uninitialized buffer with data from another buffer -for (var i = 0; i < buf.length; i++) { - buf[i] = otherBuf[i] -} -``` - - -### How do we fix node.js core? - -We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as -`semver-major`) which defends against one case: - -```js -var str = 16 -new Buffer(str, 'utf8') -``` - -In this situation, it's implied that the programmer intended the first argument to be a -string, since they passed an encoding as a second argument. Today, node.js will allocate -uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not -what the programmer intended. - -But this is only a partial solution, since if the programmer does `new Buffer(variable)` -(without an `encoding` parameter) there's no way to know what they intended. If `variable` -is sometimes a number, then uninitialized memory will sometimes be returned. - -### What's the real long-term fix? - -We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when -we need uninitialized memory. But that would break 1000s of packages. - -~~We believe the best solution is to:~~ - -~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~ - -~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~ - -#### Update - -We now support adding three new APIs: - -- `Buffer.from(value)` - convert from any type to a buffer -- `Buffer.alloc(size)` - create a zero-filled buffer -- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size - -This solves the core problem that affected `ws` and `bittorrent-dht` which is -`Buffer(variable)` getting tricked into taking a number argument. - -This way, existing code continues working and the impact on the npm ecosystem will be -minimal. Over time, npm maintainers can migrate performance-critical code to use -`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`. - - -### Conclusion - -We think there's a serious design issue with the `Buffer` API as it exists today. It -promotes insecure software by putting high-risk functionality into a convenient API -with friendly "developer ergonomics". - -This wasn't merely a theoretical exercise because we found the issue in some of the -most popular npm packages. - -Fortunately, there's an easy fix that can be applied today.

When you create a `Buffer` like -this, you **MUST** overwrite the contents before returning it to the user. - -From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size): - -> `new Buffer(size)` -> -> - `size` Number -> -> The underlying memory for `Buffer` instances created in this way is not initialized. -> **The contents of a newly created `Buffer` are unknown and could contain sensitive -> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes. - -(Emphasis our own.) - -Whenever the programmer intended to create an uninitialized `Buffer` you often see code -like this: - -```js -var buf = new Buffer(16) - -// Immediately overwrite the uninitialized buffer with data from another buffer -for (var i = 0; i < buf.length; i++) { - buf[i] = otherBuf[i] -} -``` - - -### Would this ever be a problem in real code? - -Yes. It's surprisingly common to forget to check the type of your variables in a -dynamically-typed language like JavaScript. - -Usually the consequences of assuming the wrong type is that your program crashes with an -uncaught exception. But the failure mode for forgetting to check the type of arguments to -the `Buffer` constructor is more catastrophic. - -Here's an example of a vulnerable service that takes a JSON payload and converts it to -hex: - -```js -// Take a JSON payload {str: "some string"} and convert it to hex -var server = http.createServer(function (req, res) { - var data = '' - req.setEncoding('utf8') - req.on('data', function (chunk) { - data += chunk - }) - req.on('end', function () { - var body = JSON.parse(data) - res.end(new Buffer(body.str).toString('hex')) - }) -}) - -server.listen(8080) -``` - -In this example, an http client just has to send: - -```json -{ - "str": 1000 -} -``` - -and it will get back 1,000 bytes of uninitialized memory from the server. - -This is a very serious bug. It's similar in severity to the -[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process -memory by remote attackers. - - -### Which real-world packages were vulnerable? - -#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht) - -[Mathias Buus](https://github.com/mafintosh) and I -([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages, -[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow -anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get -them to reveal 20 bytes at a time of uninitialized memory from the node.js process. - -Here's -[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8) -that fixed it. We released a new fixed version, created a -[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all -vulnerable versions on npm so users will get a warning to upgrade to a newer version. - -#### [`ws`](https://www.npmjs.com/package/ws) - -That got us wondering if there were other vulnerable packages. Sure enough, within a short -period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the -most popular WebSocket implementation in node.js. - -If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as -expected, then uninitialized server memory would be disclosed to the remote peer. - -These were the vulnerable methods: - -```js -socket.send(number) -socket.ping(number) -socket.pong(number) -``` - -Here's a vulnerable socket server with some echo functionality: - -```js -server.on('connection', function (socket) { - socket.on('message', function (message) { - message = JSON.parse(message) - if (message.type === 'echo') { - socket.send(message.data) // send back the user's message - } - }) -}) -``` - -`socket.send(number)` called on the server, will disclose server memory. - -Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue -was fixed, with a more detailed explanation. Props to -[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the -[Node Security Project disclosure](https://nodesecurity.io/advisories/67). - - -### What's the solution? - -It's important that node.js offers a fast way to get memory otherwise performance-critical -applications would needlessly get a lot slower. - -But we need a better way to *signal our intent* as programmers. **When we want -uninitialized memory, we should request it explicitly.** - -Sensitive functionality should not be packed into a developer-friendly API that loosely -accepts many different types. This type of API encourages the lazy practice of passing -variables in without checking the type very carefully. - -#### A new API: `Buffer.allocUnsafe(number)` - -The functionality of creating buffers with uninitialized memory should be part of another -API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that -frequently gets user input of all sorts of different types passed into it. - -```js -var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory! - -// Immediately overwrite the uninitialized buffer with data from another buffer -for (var i = 0; i < buf.length; i++) { - buf[i] = otherBuf[i] -} -``` - - -### How do we fix node.js core? - -We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as -`semver-major`) which defends against one case: - -```js -var str = 16 -new Buffer(str, 'utf8') -``` - -In this situation, it's implied that the programmer intended the first argument to be a -string, since they passed an encoding as a second argument. Today, node.js will allocate -uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not -what the programmer intended. - -But this is only a partial solution, since if the programmer does `new Buffer(variable)` -(without an `encoding` parameter) there's no way to know what they intended. If `variable` -is sometimes a number, then uninitialized memory will sometimes be returned. - -### What's the real long-term fix? - -We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when -we need uninitialized memory. But that would break 1000s of packages. - -~~We believe the best solution is to:~~ - -~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~ - -~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~ - -#### Update - -We now support adding three new APIs: - -- `Buffer.from(value)` - convert from any type to a buffer -- `Buffer.alloc(size)` - create a zero-filled buffer -- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size - -This solves the core problem that affected `ws` and `bittorrent-dht` which is -`Buffer(variable)` getting tricked into taking a number argument. - -This way, existing code continues working and the impact on the npm ecosystem will be -minimal. Over time, npm maintainers can migrate performance-critical code to use -`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`. - - -### Conclusion - -We think there's a serious design issue with the `Buffer` API as it exists today. It -promotes insecure software by putting high-risk functionality into a convenient API -with friendly "developer ergonomics". - -This wasn't merely a theoretical exercise because we found the issue in some of the -most popular npm packages. - -Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of -`buffer`. - -```js -var Buffer = require('safe-buffer').Buffer -``` - -Eventually, we hope that node.js core can switch to this new, safer behavior. We believe -the impact on the ecosystem would be minimal since it's not a breaking change. -Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while -older, insecure packages would magically become safe from this attack vector. - - -## links - -- [Node.js PR: buffer: throw if both length and enc are passed](https://github.com/nodejs/node/pull/4514) -- [Node Security Project disclosure for `ws`](https://nodesecurity.io/advisories/67) -- [Node Security Project disclosure for`bittorrent-dht`](https://nodesecurity.io/advisories/68) - - -## credit - -The original issues in `bittorrent-dht` -([disclosure](https://nodesecurity.io/advisories/68)) and -`ws` ([disclosure](https://nodesecurity.io/advisories/67)) were discovered by -[Mathias Buus](https://github.com/mafintosh) and -[Feross Aboukhadijeh](http://feross.org/). - -Thanks to [Adam Baldwin](https://github.com/evilpacket) for helping disclose these issues -and for his work running the [Node Security Project](https://nodesecurity.io/). - -Thanks to [John Hiesey](https://github.com/jhiesey) for proofreading this README and -auditing the code. - - -## license - -MIT.

Before Node.js 8, this buffer contained - *arbitrary memory* for performance reasons, which could include anything ranging from - program source code to passwords and encryption keys. -- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of - the string `'abc'`. A second argument could specify another encoding: For example, - `new Buffer(string, 'base64')` could be used to convert a Base64 string into the original - sequence of bytes that it represents. -- There are several other combinations of arguments. - -This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell -what exactly the contents of the generated buffer are* without knowing the type of `foo`. - -Sometimes, the value of `foo` comes from an external source. For example, this function -could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form: - -``` -function stringToBase64(req, res) { - // The request body should have the format of `{ string: 'foobar' }` - const rawBytes = new Buffer(req.body.string) - const encoded = rawBytes.toString('base64') - res.end({ encoded: encoded }) -} -``` - -Note that this code does *not* validate the type of `req.body.string`: - -- `req.body.string` is expected to be a string. If this is the case, all goes well. -- `req.body.string` is controlled by the client that sends the request. -- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes: - - Before Node.js 8, the content would be uninitialized - - After Node.js 8, the content would be `50` bytes with the value `0` - -Because of the missing type check, an attacker could intentionally send a number -as part of the request. Using this, they can either: - -- Read uninitialized memory. This **will** leak passwords, encryption keys and other - kinds of sensitive information. (Information leak) -- Force the program to allocate a large amount of memory. For example, when specifying - `500000000` as the input value, each request will allocate 500MB of memory. - This can be used to either exhaust the memory available of a program completely - and make it crash, or slow it down significantly. (Denial of Service) - -Both of these scenarios are considered serious security issues in a real-world -web server context. - -when using `Buffer.from(req.body.string)` instead, passing a number will always -throw an exception instead, giving a controlled behaviour that can always be -handled by the program. - - -### The `Buffer()` constructor has been deprecated for a while. Is this really an issue? - -Surveys of code in the `npm` ecosystem have shown that the `Buffer()` constructor is still -widely used.

The set -of primitive `operators` is: - -* `<` Less than -* `<=` Less than or equal to -* `>` Greater than -* `>=` Greater than or equal to -* `=` Equal. If no operator is specified, then equality is assumed, - so this operator is optional, but MAY be included. - -For example, the comparator `>=1.2.7` would match the versions -`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` -or `1.1.0`. - -Comparators can be joined by whitespace to form a `comparator set`, -which is satisfied by the **intersection** of all of the comparators -it includes. - -A range is composed of one or more comparator sets, joined by `||`. A -version matches a range if and only if every comparator in at least -one of the `||`-separated comparator sets is satisfied by the version. - -For example, the range `>=1.2.7 <1.3.0` would match the versions -`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, -or `1.1.0`. - -The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, -`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. - -### Prerelease Tags - -If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then -it will only be allowed to satisfy comparator sets if at least one -comparator with the same `[major, minor, patch]` tuple also has a -prerelease tag. - -For example, the range `>1.2.3-alpha.3` would be allowed to match the -version `1.2.3-alpha.7`, but it would *not* be satisfied by -`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater -than" `1.2.3-alpha.3` according to the SemVer sort rules. The version -range only accepts prerelease tags on the `1.2.3` version. The -version `3.4.5` *would* satisfy the range, because it does not have a -prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. - -The purpose for this behavior is twofold.

By including a prerelease tag in the range, -the user is indicating that they are aware of the risk. However, it -is still not appropriate to assume that they have opted into taking a -similar risk on the *next* set of prerelease versions. - -Note that this behavior can be suppressed (treating all prerelease -versions as if they were normal versions, for the purpose of range -matching) by setting the `includePrerelease` flag on the options -object to any -[functions](https://github.com/npm/node-semver#functions) that do -range matching. - -#### Prerelease Identifiers - -The method `.inc` takes an additional `identifier` string argument that -will append the value of the string as a prerelease identifier: - -```javascript -semver.inc('1.2.3', 'prerelease', 'beta') -// '1.2.4-beta.0' -``` - -command-line example: - -```bash -$ semver 1.2.3 -i prerelease --preid beta -1.2.4-beta.0 -``` - -Which then can be used to increment further: - -```bash -$ semver 1.2.4-beta.0 -i prerelease -1.2.4-beta.1 -``` - -### Advanced Range Syntax - -Advanced range syntax desugars to primitive comparators in -deterministic ways. - -Advanced ranges may be combined in the same way as primitive -comparators using white space or `||`. - -#### Hyphen Ranges `X.Y.Z - A.B.C` - -Specifies an inclusive set. - -* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` - -If a partial version is provided as the first version in the inclusive -range, then the missing pieces are replaced with zeroes. - -* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` - -If a partial version is provided as the second version in the -inclusive range, then all versions that start with the supplied parts -of the tuple are accepted, but nothing that would be greater than the -provided tuple parts. - -* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0` -* `1.2.3 - 2` := `>=1.2.3 <3.0.0` - -#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` - -Any of `X`, `x`, or `*` may be used to "stand in" for one of the -numeric values in the `[major, minor, patch]` tuple. - -* `*` := `>=0.0.0` (Any version satisfies) -* `1.x` := `>=1.0.0 <2.0.0` (Matching major version) -* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions) - -A partial version range is treated as an X-Range, so the special -character is in fact optional. - -* `""` (empty string) := `*` := `>=0.0.0` -* `1` := `1.x.x` := `>=1.0.0 <2.0.0` -* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0` - -#### Tilde Ranges `~1.2.3` `~1.2` `~1` - -Allows patch-level changes if a minor version is specified on the -comparator.

The - `hilo` argument must be either the string `'>'` or `'<'`. (This is - the function called by `gtr` and `ltr`.) -* `intersects(range)`: Return true if any of the ranges comparators intersect - -Note that, since ranges may be non-contiguous, a version might not be -greater than a range, less than a range, *or* satisfy a range! For -example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` -until `2.0.0`, so the version `1.2.10` would not be greater than the -range (because `2.0.1` satisfies, which is higher), nor less than the -range (since `1.2.8` satisfies, which is lower), and it also does not -satisfy the range. - -If you want to know if a version satisfies or does not satisfy a -range, use the `satisfies(version, range)` function. - -### Coercion - -* `coerce(version)`: Coerces a string to semver if possible - -This aims to provide a very forgiving translation of a non-semver string to -semver. It looks for the first digit in a string, and consumes all -remaining characters which satisfy at least a partial semver (e.g., `1`, -`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer -versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All -surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes -`3.4.0`).

Returns `null` if conversion failed. - - -SFTP methods ------------- - -* **(constructor)**(< _object_ >config[, < _string_ >remoteIdentRaw]) - Creates and returns a new SFTP instance. `remoteIdentRaw` can be the raw SSH identification string of the remote party. This is used to change internal behavior based on particular SFTP implementations. `config` can contain: - - * **server** - _boolean_ - Set to `true` to create an instance in server mode. **Default:** `false` - - * **debug** - _function_ - Set this to a function that receives a single string argument to get detailed (local) debug information. **Default:** (none) - - - -**Client-only methods** - -* **fastGet**(< _string_ >remotePath, < _string_ >localPath[, < _object_ >options], < _function_ >callback) - _(void)_ - Downloads a file at `remotePath` to `localPath` using parallel reads for faster throughput. `options` can have the following properties: - - * **concurrency** - _integer_ - Number of concurrent reads **Default:** `64` - - * **chunkSize** - _integer_ - Size of each read in bytes **Default:** `32768` - - * **step** - _function_(< _integer_ >total_transferred, < _integer_ >chunk, < _integer_ >total) - Called every time a part of a file was transferred - - `callback` has 1 parameter: < _Error_ >err. - -* **fastPut**(< _string_ >localPath, < _string_ >remotePath[, < _object_ >options], < _function_ >callback) - _(void)_ - Uploads a file from `localPath` to `remotePath` using parallel reads for faster throughput. `options` can have the following properties: - - * **concurrency** - _integer_ - Number of concurrent reads **Default:** `64` - - * **chunkSize** - _integer_ - Size of each read in bytes **Default:** `32768` - - * **step** - _function_(< _integer_ >total_transferred, < _integer_ >chunk, < _integer_ >total) - Called every time a part of a file was transferred - - * **mode** - _mixed_ - Integer or string representing the file mode to set for the uploaded file. - - `callback` has 1 parameter: < _Error_ >err. - -* **createReadStream**(< _string_ >path[, < _object_ >options]) - _ReadStream_ - Returns a new readable stream for `path`. `options` has the following defaults: - - ```javascript - { flags: 'r', - encoding: null, - handle: null, - mode: 0o666, - autoClose: true - } - ``` - - `options` can include `start` and `end` values to read a range of bytes from the file instead of the entire file. Both `start` and `end` are inclusive and start at 0. The `encoding` can be `'utf8'`, `'ascii'`, or `'base64'`. - - If `autoClose` is false, then the file handle won't be closed, even if there's an error. It is your responsibility to close it and make sure there's no file handle leak. If `autoClose` is set to true (default behavior), on `error` or `end` the file handle will be closed automatically. - - An example to read the last 10 bytes of a file which is 100 bytes long: - - ```javascript - sftp.createReadStream('sample.txt', {start: 90, end: 99}); - ``` - -* **createWriteStream**(< _string_ >path[, < _object_ >options]) - _WriteStream_ - Returns a new writable stream for `path`. `options` has the following defaults: - - ```javascript - { - flags: 'w', - encoding: null, - mode: 0o666, - autoClose: true - } - ``` - - `options` may also include a `start` option to allow writing data at some position past the beginning of the file. Modifying a file rather than replacing it may require a flags mode of 'r+' rather than the default mode 'w'. - - If 'autoClose' is set to false and you pipe to this stream, this stream will not automatically close after there is no more data upstream -- allowing future pipes and/or manual writes. - -* **open**(< _string_ >filename, < _string_ >flags, [< _mixed_ >attrs_mode, ]< _function_ >callback) - _(void)_ - Opens a file `filename` with `flags` with optional _ATTRS_ object or file mode `attrs_mode`. `flags` is any of the flags supported by `fs.open` (except sync flag). `callback` has 2 parameters: < _Error_ >err, < _Buffer_ >handle. - -* **close**(< _Buffer_ >handle, < _function_ >callback) - _(void)_ - Closes the resource associated with `handle` given by open() or opendir(). `callback` has 1 parameter: < _Error_ >err. - -* **read**(< _Buffer_ >handle, < _Buffer_ >buffer, < _integer_ >offset, < _integer_ >length, < _integer_ >position, < _function_ >callback) - _(void)_ - Reads `length` bytes from the resource associated with `handle` starting at `position` and stores the bytes in `buffer` starting at `offset`. `callback` has 4 parameters: < _Error_ >err, < _integer_ >bytesRead, < _Buffer_ >buffer (offset adjusted), < _integer_ >position. - -* **write**(< _Buffer_ >handle, < _Buffer_ >buffer, < _integer_ >offset, < _integer_ >length, < _integer_ >position, < _function_ >callback) - _(void)_ - Writes `length` bytes from `buffer` starting at `offset` to the resource associated with `handle` starting at `position`. `callback` has 1 parameter: < _Error_ >err. - -* **fstat**(< _Buffer_ >handle, < _function_ >callback) - _(void)_ - Retrieves attributes for the resource associated with `handle`. `callback` has 2 parameters: < _Error_ >err, < _Stats_ >stats. - -* **fsetstat**(< _Buffer_ >handle, < _ATTRS_ >attributes, < _function_ >callback) - _(void)_ - Sets the attributes defined in `attributes` for the resource associated with `handle`. `callback` has 1 parameter: < _Error_ >err. - -* **futimes**(< _Buffer_ >handle, < _mixed_ >atime, < _mixed_ >mtime, < _function_ >callback) - _(void)_ - Sets the access time and modified time for the resource associated with `handle`. `atime` and `mtime` can be Date instances or UNIX timestamps. `callback` has 1 parameter: < _Error_ >err. - -* **fchown**(< _Buffer_ >handle, < _integer_ >uid, < _integer_ >gid, < _function_ >callback) - _(void)_ - Sets the owner for the resource associated with `handle`. `callback` has 1 parameter: < _Error_ >err. - -* **fchmod**(< _Buffer_ >handle, < _mixed_ >mode, < _function_ >callback) - _(void)_ - Sets the mode for the resource associated with `handle`. `mode` can be an integer or a string containing an octal number. `callback` has 1 parameter: < _Error_ >err. - -* **opendir**(< _string_ >path, < _function_ >callback) - _(void)_ - Opens a directory `path`. `callback` has 2 parameters: < _Error_ >err, < _Buffer_ >handle. - -* **readdir**(< _mixed_ >location, < _function_ >callback) - _(void)_ - Retrieves a directory listing. `location` can either be a _Buffer_ containing a valid directory handle from opendir() or a _string_ containing the path to a directory. `callback` has 2 parameters: < _Error_ >err, < _mixed_ >list. `list` is an _Array_ of `{ filename: 'foo', longname: '....', attrs: {...} }` style objects (attrs is of type _ATTR_). If `location` is a directory handle, this function may need to be called multiple times until `list` is boolean false, which indicates that no more directory entries are available for that directory handle. - -* **unlink**(< _string_ >path, < _function_ >callback) - _(void)_ - Removes the file/symlink at `path`. `callback` has 1 parameter: < _Error_ >err. - -* **rename**(< _string_ >srcPath, < _string_ >destPath, < _function_ >callback) - _(void)_ - Renames/moves `srcPath` to `destPath`. `callback` has 1 parameter: < _Error_ >err. - -* **mkdir**(< _string_ >path, [< _ATTRS_ >attributes, ]< _function_ >callback) - _(void)_ - Creates a new directory `path`. `callback` has 1 parameter: < _Error_ >err. - -* **rmdir**(< _string_ >path, < _function_ >callback) - _(void)_ - Removes the directory at `path`. `callback` has 1 parameter: < _Error_ >err. - -* **stat**(< _string_ >path, < _function_ >callback) - _(void)_ - Retrieves attributes for `path`. `callback` has 2 parameter: < _Error_ >err, < _Stats_ >stats. - -* **lstat**(< _string_ >path, < _function_ >callback) - _(void)_ - Retrieves attributes for `path`.

But the failure mode for forgetting to check the type of arguments to -the `Buffer` constructor is more catastrophic. - -Here's an example of a vulnerable service that takes a JSON payload and converts it to -hex: - -```js -// Take a JSON payload {str: "some string"} and convert it to hex -var server = http.createServer(function (req, res) { - var data = '' - req.setEncoding('utf8') - req.on('data', function (chunk) { - data += chunk - }) - req.on('end', function () { - var body = JSON.parse(data) - res.end(new Buffer(body.str).toString('hex')) - }) -}) - -server.listen(8080) -``` - -In this example, an http client just has to send: - -```json -{ - "str": 1000 -} -``` - -and it will get back 1,000 bytes of uninitialized memory from the server. - -This is a very serious bug. It's similar in severity to the -[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process -memory by remote attackers. - - -### Which real-world packages were vulnerable? - -#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht) - -[Mathias Buus](https://github.com/mafintosh) and I -([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages, -[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow -anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get -them to reveal 20 bytes at a time of uninitialized memory from the node.js process. - -Here's -[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8) -that fixed it. We released a new fixed version, created a -[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all -vulnerable versions on npm so users will get a warning to upgrade to a newer version. - -#### [`ws`](https://www.npmjs.com/package/ws) - -That got us wondering if there were other vulnerable packages. Sure enough, within a short -period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the -most popular WebSocket implementation in node.js. - -If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as -expected, then uninitialized server memory would be disclosed to the remote peer. - -These were the vulnerable methods: - -```js -socket.send(number) -socket.ping(number) -socket.pong(number) -``` - -Here's a vulnerable socket server with some echo functionality: - -```js -server.on('connection', function (socket) { - socket.on('message', function (message) { - message = JSON.parse(message) - if (message.type === 'echo') { - socket.send(message.data) // send back the user's message - } - }) -}) -``` - -`socket.send(number)` called on the server, will disclose server memory. - -Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue -was fixed, with a more detailed explanation. Props to -[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the -[Node Security Project disclosure](https://nodesecurity.io/advisories/67). - - -### What's the solution? - -It's important that node.js offers a fast way to get memory otherwise performance-critical -applications would needlessly get a lot slower. - -But we need a better way to *signal our intent* as programmers. **When we want -uninitialized memory, we should request it explicitly.** - -Sensitive functionality should not be packed into a developer-friendly API that loosely -accepts many different types. This type of API encourages the lazy practice of passing -variables in without checking the type very carefully. - -#### A new API: `Buffer.allocUnsafe(number)` - -The functionality of creating buffers with uninitialized memory should be part of another -API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that -frequently gets user input of all sorts of different types passed into it. - -```js -var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory! - -// Immediately overwrite the uninitialized buffer with data from another buffer -for (var i = 0; i < buf.length; i++) { - buf[i] = otherBuf[i] -} -``` - - -### How do we fix node.js core? - -We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as -`semver-major`) which defends against one case: - -```js -var str = 16 -new Buffer(str, 'utf8') -``` - -In this situation, it's implied that the programmer intended the first argument to be a -string, since they passed an encoding as a second argument. Today, node.js will allocate -uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not -what the programmer intended. - -But this is only a partial solution, since if the programmer does `new Buffer(variable)` -(without an `encoding` parameter) there's no way to know what they intended. If `variable` -is sometimes a number, then uninitialized memory will sometimes be returned. - -### What's the real long-term fix? - -We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when -we need uninitialized memory. But that would break 1000s of packages. - -~~We believe the best solution is to:~~ - -~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~ - -~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~ - -#### Update - -We now support adding three new APIs: - -- `Buffer.from(value)` - convert from any type to a buffer -- `Buffer.alloc(size)` - create a zero-filled buffer -- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size - -This solves the core problem that affected `ws` and `bittorrent-dht` which is -`Buffer(variable)` getting tricked into taking a number argument. - -This way, existing code continues working and the impact on the npm ecosystem will be -minimal. Over time, npm maintainers can migrate performance-critical code to use -`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`. - - -### Conclusion - -We think there's a serious design issue with the `Buffer` API as it exists today. It -promotes insecure software by putting high-risk functionality into a convenient API -with friendly "developer ergonomics". - -This wasn't merely a theoretical exercise because we found the issue in some of the -most popular npm packages. - -Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of -`buffer`. - -```js -var Buffer = require('safe-buffer').Buffer -``` - -Eventually, we hope that node.js core can switch to this new, safer behavior. We believe -the impact on the ecosystem would be minimal since it's not a breaking change. -Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while -older, insecure packages would magically become safe from this attack vector. - - -## links - -- [Node.js PR: buffer: throw if both length and enc are passed](https://github.com/nodejs/node/pull/4514) -- [Node Security Project disclosure for `ws`](https://nodesecurity.io/advisories/67) -- [Node Security Project disclosure for`bittorrent-dht`](https://nodesecurity.io/advisories/68) - - -## credit - -The original issues in `bittorrent-dht` -([disclosure](https://nodesecurity.io/advisories/68)) and -`ws` ([disclosure](https://nodesecurity.io/advisories/67)) were discovered by -[Mathias Buus](https://github.com/mafintosh) and -[Feross Aboukhadijeh](http://feross.org/). - -Thanks to [Adam Baldwin](https://github.com/evilpacket) for helping disclose these issues -and for his work running the [Node Security Project](https://nodesecurity.io/). - -Thanks to [John Hiesey](https://github.com/jhiesey) for proofreading this README and -auditing the code. - - -## license - -MIT.
