We guarantee `BSONError.isBSONError()` checks will pass according to semver guidelines, but errors may be sub-classed or their messages may change at any time, even patch releases, as we see fit to increase the helpfulness of the errors. + +Any new errors we add to the driver will directly extend an existing error class and no existing error will be moved to a different parent class outside of a major release. +This means `BSONError.isBSONError()` will always be able to accurately capture the errors that our BSON library throws. + +Hypothetical example: A collection in our Db has an issue with UTF-8 data: + +```ts +let documentCount = 0; +const cursor = collection.find({}, { utf8Validation: true }); +try { + for await (const doc of cursor) documentCount += 1; +} catch (error) { + if (BSONError.isBSONError(error)) { + console.log(`Found the troublemaker UTF-8!: ${documentCount} ${error.message}`); + return documentCount; + } + throw error; +} +``` + +## React Native + +BSON requires that `TextEncoder`, `TextDecoder`, `atob`, `btoa`, and `crypto.getRandomValues` are available globally. These are present in most Javascript runtimes but require polyfilling in React Native. Polyfills for the missing functionality can be installed with the following command: +```sh +npm install --save react-native-get-random-values text-encoding-polyfill base-64 +``` + +The following snippet should be placed at the top of the entrypoint (by default this is the root `index.js` file) for React Native projects using the BSON library. These lines must be placed for any code that imports `BSON`. + +```typescript +// Required Polyfills For ReactNative +import {encode, decode} from 'base-64'; +if (global.btoa == null) { + global.btoa = encode; +} +if (global.atob == null) { + global.atob = decode; +} +import 'text-encoding-polyfill'; +import 'react-native-get-random-values'; +``` + +Finally, import the `BSON` library like so: + +```typescript +import { BSON, EJSON } from 'bson'; +``` + +This will cause React Native to import the `node_modules/bson/lib/bson.cjs` bundle (see the `"react-native"` setting we have in the `"exports"` section of our [package.json](./package.json).) + +### Technical Note about React Native module import + +The `"exports"` definition in our `package.json` will result in BSON's CommonJS bundle being imported in a React Native project instead of the ES module bundle. Importing the CommonJS bundle is necessary because BSON's ES module bundle of BSON uses top-level await, which is not supported syntax in [React Native's runtime hermes](https://hermesengine.dev/). + +## 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.

+await client.connect(); +const collection = client.db().collection('collection'); + +try { + await collection.insertOne({ _id: 1 }); + await collection.insertOne({ _id: 1 }); // duplicate key error +} catch (error) { + if (error instanceof MongoServerError) { + console.log(`Error worth logging: ${error}`);

Conversions are still accurate as we make use of BigInt in the conversion process, but in the case of `unsigned long long` we simply cannot represent some possible output values in JavaScript. For example, converting the JavaScript number `-1` to a Web IDL `unsigned long long` is supposed to produce the Web IDL value `18446744073709551615`. Since we are representing our Web IDL values in JavaScript, we can't represent `18446744073709551615`, so we instead the best we could do is `18446744073709551616` as the output. + +To mitigate this, we could return the raw BigInt value from the conversion function, but right now it is not implemented. If your use case requires such precision, [file an issue](https://github.com/jsdom/webidl-conversions/issues/new). + +On the other hand, `long long` conversion is always accurate, since the input value can never be more precise than the output value. + +### A note on `BufferSource` types + +All of the `BufferSource` types will throw when the relevant `ArrayBuffer` has been detached. This technically is not part of the [specified conversion algorithm](https://heycam.github.io/webidl/#es-buffer-source-types), but instead part of the [getting a reference/getting a copy](https://heycam.github.io/webidl/#ref-for-dfn-get-buffer-source-reference%E2%91%A0) algorithms. We've consolidated them here for convenience and ease of implementation, but if there is a need to separate them in the future, please open an issue so we can investigate. + +## Background + +What's actually going on here, conceptually, is pretty weird. Let's try to explain. + +Web IDL, as part of its madness-inducing design, has its own type system. When people write algorithms in web platform specs, they usually operate on Web IDL values, i.e. instances of Web IDL types. For example, if they were specifying the algorithm for our `doStuff` operation above, they would treat `x` as a Web IDL value of [Web IDL type `boolean`](http://heycam.github.io/webidl/#idl-boolean). Crucially, they would _not_ treat `x` as a JavaScript variable whose value is either the JavaScript `true` or `false`. They're instead working in a different type system altogether, with its own rules. + +Separately from its type system, Web IDL defines a ["binding"](http://heycam.github.io/webidl/#ecmascript-binding) of the type system into JavaScript. This contains rules like: when you pass a JavaScript value to the JavaScript method that manifests a given Web IDL operation, how does that get converted into a Web IDL value? For example, a JavaScript `true` passed in the position of a Web IDL `boolean` argument becomes a Web IDL `true`. But, a JavaScript `true` passed in the position of a [Web IDL `unsigned long`](http://heycam.github.io/webidl/#idl-unsigned-long) becomes a Web IDL `1`. And so on. + +Finally, we have the actual implementation code. This is usually C++, although these days [some smart people are using Rust](https://github.com/servo/servo). The implementation, of course, has its own type system. So when they implement the Web IDL algorithms, they don't actually use Web IDL values, since those aren't "real" outside of specs. Instead, implementations apply the Web IDL binding rules in such a way as to convert incoming JavaScript values into C++ values. For example, if code in the browser called `doStuff(true, true)`, then the implementation code would eventually receive a C++ `bool` containing `true` and a C++ `uint32_t` containing `1`. + +The upside of all this is that implementations can abstract all the conversion logic away, letting Web IDL handle it, and focus on implementing the relevant methods in C++ with values of the correct type already provided. That is payoff of Web IDL, in a nutshell. + +And getting to that payoff is the goal of _this_ project—but for JavaScript implementations, instead of C++ ones. That is, this library is designed to make it easier for JavaScript developers to write functions that behave like a given Web IDL operation. So conceptually, the conversion pipeline, which in its general form is JavaScript values ↦ Web IDL values ↦ implementation-language values, in this case becomes JavaScript values ↦ Web IDL values ↦ JavaScript values. And that intermediate step is where all the logic is performed: a JavaScript `true` becomes a Web IDL `1` in an unsigned long context, which then becomes a JavaScript `1`. + +## Don't use this + +Seriously, why would you ever use this? You really shouldn't. Web IDL is … strange, and you shouldn't be emulating its semantics. If you're looking for a generic argument-processing library, you should find one with better rules than those from Web IDL. In general, your JavaScript should not be trying to become more like Web IDL; if anything, we should fix Web IDL to make it more like JavaScript. + +The _only_ people who should use this are those trying to create faithful implementations (or polyfills) of web platform interfaces defined in Web IDL. Its main consumer is the [jsdom](https://github.com/jsdom/jsdom) project. diff --git a/1_ActivityWatchProducer/node_modules/webidl-conversions/lib/index.js b/1_ActivityWatchProducer/node_modules/webidl-conversions/lib/index.js new file mode 100644 index 00000000..0229347c --- /dev/null +++ b/1_ActivityWatchProducer/node_modules/webidl-conversions/lib/index.js @@ -0,0 +1,450 @@ +"use strict"; + +function makeException(ErrorType, message, options) { + if (options.globals) { + ErrorType = options.globals[ErrorType.name]; + } + return new ErrorType(`${options.context ? options.context : "Value"} ${message}.`); +} + +function toNumber(value, options) { + if (typeof value === "bigint") { + throw makeException(TypeError, "is a BigInt which cannot be converted to a number", options); + } + if (!options.globals) { + return Number(value); + } + return options.globals.Number(value); +} + +// Round x to the nearest integer, choosing the even integer if it lies halfway between two. +function evenRound(x) { + // There are four cases for numbers with fractional part being .5: + // + // case | x | floor(x) | round(x) | expected | x <> 0 | x % 1 | x & 1 | example + // 1 | 2n + 0.5 | 2n | 2n + 1 | 2n | > | 0.5 | 0 | 0.5 -> 0 + // 2 | 2n + 1.5 | 2n + 1 | 2n + 2 | 2n + 2 | > | 0.5 | 1 | 1.5 -> 2 + // 3 | -2n - 0.5 | -2n - 1 | -2n | -2n | < | -0.5 | 0 | -0.5 -> 0 + // 4 | -2n - 1.5 | -2n - 2 | -2n - 1 | -2n - 2 | < | -0.5 | 1 | -1.5 -> -2 + // (where n is a non-negative integer) + // + // Branch here for cases 1 and 4 + if ((x > 0 && (x % 1) === +0.5 && (x & 1) === 0) || + (x < 0 && (x % 1) === -0.5 && (x & 1) === 1)) { + return censorNegativeZero(Math.floor(x)); + } + + return censorNegativeZero(Math.round(x)); +} + +function integerPart(n) { + return censorNegativeZero(Math.trunc(n)); +} + +function sign(x) { + return x < 0 ? -1 : 1; +} + +function modulo(x, y) { + // https://tc39.github.io/ecma262/#eqn-modulo + // Note that http://stackoverflow.com/a/4467559/3191 does NOT work for large modulos + const signMightNotMatch = x % y; + if (sign(y) !== sign(signMightNotMatch)) { + return signMightNotMatch + y; + } + return signMightNotMatch; +} + +function censorNegativeZero(x) { + return x === 0 ? 0 : x; +} + +function createIntegerConversion(bitLength, { unsigned }) { + let lowerBound, upperBound; + if (unsigned) { + lowerBound = 0; + upperBound = 2 ** bitLength - 1; + } else { + lowerBound = -(2 ** (bitLength - 1)); + upperBound = 2 ** (bitLength - 1) - 1; + } + + const twoToTheBitLength = 2 ** bitLength; + const twoToOneLessThanTheBitLength = 2 ** (bitLength - 1); + + return (value, options = {}) => { + let x = toNumber(value, options); + x = censorNegativeZero(x); + + if (options.enforceRange) { + if (!Number.isFinite(x)) { + throw makeException(TypeError, "is not a finite number", options); + } + + x = integerPart(x); + + if (x < lowerBound || x > upperBound) { + throw makeException( + TypeError, + `is outside the accepted range of ${lowerBound} to ${upperBound}, inclusive`, + options + ); + } + + return x; + } + + if (!Number.isNaN(x) && options.clamp) { + x = Math.min(Math.max(x, lowerBound), upperBound); + x = evenRound(x); + return x; + } + + if (!Number.isFinite(x) || x === 0) { + return 0; + } + x = integerPart(x); + + // Math.pow(2, 64) is not accurately representable in JavaScript, so try to avoid these per-spec operations if + // possible.

This can + * happen, for instance, when the child process has already exited. + * + * `subprocess.send()` will return `false` if the channel has closed or when the + * backlog of unsent messages exceeds a threshold that makes it unwise to send + * more. Otherwise, the method returns `true`. The `callback` function can be + * used to implement flow control. + * + * #### Example: sending a server object + * + * The `sendHandle` argument can be used, for instance, to pass the handle of + * a TCP server object to the child process as illustrated in the example below: + * + * ```js + * const subprocess = require('child_process').fork('subprocess.js'); + * + * // Open up the server object and send the handle. + * const server = require('net').createServer(); + * server.on('connection', (socket) => { + * socket.end('handled by parent'); + * }); + * server.listen(1337, () => { + * subprocess.send('server', server); + * }); + * ``` + * + * The child would then receive the server object as: + * + * ```js + * process.on('message', (m, server) => { + * if (m === 'server') { + * server.on('connection', (socket) => { + * socket.end('handled by child'); + * }); + * } + * }); + * ``` + * + * Once the server is now shared between the parent and child, some connections + * can be handled by the parent and some by the child. + * + * While the example above uses a server created using the `net` module, `dgram`module servers use exactly the same workflow with the exceptions of listening on + * a `'message'` event instead of `'connection'` and using `server.bind()` instead + * of `server.listen()`. This is, however, currently only supported on Unix + * platforms. + * + * #### Example: sending a socket object + * + * Similarly, the `sendHandler` argument can be used to pass the handle of a + * socket to the child process. The example below spawns two children that each + * handle connections with "normal" or "special" priority: + * + * ```js + * const { fork } = require('child_process'); + * const normal = fork('subprocess.js', ['normal']); + * const special = fork('subprocess.js', ['special']); + * + * // Open up the server and send sockets to child. Use pauseOnConnect to prevent + * // the sockets from being read before they are sent to the child process. + * const server = require('net').createServer({ pauseOnConnect: true }); + * server.on('connection', (socket) => { + * + * // If this is special priority... + * if (socket.remoteAddress === '74.125.127.100') { + * special.send('socket', socket); + * return; + * } + * // This is normal priority. + * normal.send('socket', socket); + * }); + * server.listen(1337); + * ``` + * + * The `subprocess.js` would receive the socket handle as the second argument + * passed to the event callback function: + * + * ```js + * process.on('message', (m, socket) => { + * if (m === 'socket') { + * if (socket) { + * // Check that the client socket exists. + * // It is possible for the socket to be closed between the time it is + * // sent and the time it is received in the child process. + * socket.end(`Request handled with ${process.argv[2]} priority`); + * } + * } + * }); + * ``` + * + * Do not use `.maxConnections` on a socket that has been passed to a subprocess. + * The parent cannot track when the socket is destroyed. + * + * Any `'message'` handlers in the subprocess should verify that `socket` exists, + * as the connection may have been closed during the time it takes to send the + * connection to the child. + * @since v0.5.9 + * @param options The `options` argument, if present, is an object used to parameterize the sending of certain types of handles. `options` supports the following properties: + */ + send(message: Serializable, callback?: (error: Error | null) => void): boolean; + send(message: Serializable, sendHandle?: SendHandle, callback?: (error: Error | null) => void): boolean; + send(message: Serializable, sendHandle?: SendHandle, options?: MessageOptions, callback?: (error: Error | null) => void): boolean; + /** + * Closes the IPC channel between parent and child, allowing the child to exit + * gracefully once there are no other connections keeping it alive.

If `async` / `await`flow and speed are both essential, a mixed approach can be applied: + * + * ```js + * const { once } = require('events'); + * const { createReadStream } = require('fs'); + * const { createInterface } = require('readline'); + * + * (async function processLineByLine() { + * try { + * const rl = createInterface({ + * input: createReadStream('big-file.txt'), + * crlfDelay: Infinity + * }); + * + * rl.on('line', (line) => { + * // Process the line. + * }); + * + * await once(rl, 'close'); + * + * console.log('File processed.'); + * } catch (err) { + * console.error(err); + * } + * })(); + * ``` + * @since v0.7.7 + * @param callback Invoked once the operation completes. + * @return `false` if `stream` wishes for the calling code to wait for the `'drain'` event to be emitted before continuing to write additional data; otherwise `true`. + */ + export function moveCursor(stream: NodeJS.WritableStream, dx: number, dy: number, callback?: () => void): boolean; +} +declare module 'node:readline' { + export * from 'readline'; +} diff --git a/2_PAC/node_modules/@types/node/readline/promises.d.ts b/2_PAC/node_modules/@types/node/readline/promises.d.ts new file mode 100644 index 00000000..8f9f06f0 --- /dev/null +++ b/2_PAC/node_modules/@types/node/readline/promises.d.ts @@ -0,0 +1,143 @@ +/** + * The `readline/promise` module provides an API for reading lines of input from a Readable stream one line at a time. + * + * @see [source](https://github.com/nodejs/node/blob/v18.0.0/lib/readline/promises.js) + * @since v17.0.0 + */ +declare module 'readline/promises' { + import { Interface as _Interface, ReadLineOptions, Completer, AsyncCompleter, Direction } from 'node:readline'; + import { Abortable } from 'node:events'; + + class Interface extends _Interface { + /** + * The rl.question() method displays the query by writing it to the output, waits for user input to be provided on input, + * then invokes the callback function passing the provided input as the first argument. + * + * When called, rl.question() will resume the input stream if it has been paused. + * + * If the readlinePromises.Interface was created with output set to null or undefined the query is not written. + * + * If the question is called after rl.close(), it returns a rejected promise. + * + * Example usage: + * + * ```js + * const answer = await rl.question('What is your favorite food?

This can + * happen, for instance, when the child process has already exited. + * + * `subprocess.send()` will return `false` if the channel has closed or when the + * backlog of unsent messages exceeds a threshold that makes it unwise to send + * more. Otherwise, the method returns `true`. The `callback` function can be + * used to implement flow control. + * + * #### Example: sending a server object + * + * The `sendHandle` argument can be used, for instance, to pass the handle of + * a TCP server object to the child process as illustrated in the example below: + * + * ```js + * const subprocess = require('child_process').fork('subprocess.js'); + * + * // Open up the server object and send the handle. + * const server = require('net').createServer(); + * server.on('connection', (socket) => { + * socket.end('handled by parent'); + * }); + * server.listen(1337, () => { + * subprocess.send('server', server); + * }); + * ``` + * + * The child would then receive the server object as: + * + * ```js + * process.on('message', (m, server) => { + * if (m === 'server') { + * server.on('connection', (socket) => { + * socket.end('handled by child'); + * }); + * } + * }); + * ``` + * + * Once the server is now shared between the parent and child, some connections + * can be handled by the parent and some by the child. + * + * While the example above uses a server created using the `net` module, `dgram`module servers use exactly the same workflow with the exceptions of listening on + * a `'message'` event instead of `'connection'` and using `server.bind()` instead + * of `server.listen()`. This is, however, currently only supported on Unix + * platforms. + * + * #### Example: sending a socket object + * + * Similarly, the `sendHandler` argument can be used to pass the handle of a + * socket to the child process. The example below spawns two children that each + * handle connections with "normal" or "special" priority: + * + * ```js + * const { fork } = require('child_process'); + * const normal = fork('subprocess.js', ['normal']); + * const special = fork('subprocess.js', ['special']); + * + * // Open up the server and send sockets to child. Use pauseOnConnect to prevent + * // the sockets from being read before they are sent to the child process. + * const server = require('net').createServer({ pauseOnConnect: true }); + * server.on('connection', (socket) => { + * + * // If this is special priority... + * if (socket.remoteAddress === '74.125.127.100') { + * special.send('socket', socket); + * return; + * } + * // This is normal priority. + * normal.send('socket', socket); + * }); + * server.listen(1337); + * ``` + * + * The `subprocess.js` would receive the socket handle as the second argument + * passed to the event callback function: + * + * ```js + * process.on('message', (m, socket) => { + * if (m === 'socket') { + * if (socket) { + * // Check that the client socket exists. + * // It is possible for the socket to be closed between the time it is + * // sent and the time it is received in the child process. + * socket.end(`Request handled with ${process.argv[2]} priority`); + * } + * } + * }); + * ``` + * + * Do not use `.maxConnections` on a socket that has been passed to a subprocess. + * The parent cannot track when the socket is destroyed. + * + * Any `'message'` handlers in the subprocess should verify that `socket` exists, + * as the connection may have been closed during the time it takes to send the + * connection to the child. + * @since v0.5.9 + * @param options The `options` argument, if present, is an object used to parameterize the sending of certain types of handles. `options` supports the following properties: + */ + send(message: Serializable, callback?: (error: Error | null) => void): boolean; + send(message: Serializable, sendHandle?: SendHandle, callback?: (error: Error | null) => void): boolean; + send(message: Serializable, sendHandle?: SendHandle, options?: MessageOptions, callback?: (error: Error | null) => void): boolean; + /** + * Closes the IPC channel between parent and child, allowing the child to exit + * gracefully once there are no other connections keeping it alive.

We guarantee `BSONError.isBSONError()` checks will pass according to semver guidelines, but errors may be sub-classed or their messages may change at any time, even patch releases, as we see fit to increase the helpfulness of the errors. + +Any new errors we add to the driver will directly extend an existing error class and no existing error will be moved to a different parent class outside of a major release. +This means `BSONError.isBSONError()` will always be able to accurately capture the errors that our BSON library throws. + +Hypothetical example: A collection in our Db has an issue with UTF-8 data: + +```ts +let documentCount = 0; +const cursor = collection.find({}, { utf8Validation: true }); +try { + for await (const doc of cursor) documentCount += 1; +} catch (error) { + if (BSONError.isBSONError(error)) { + console.log(`Found the troublemaker UTF-8!: ${documentCount} ${error.message}`); + return documentCount; + } + throw error; +} +``` + +## React Native + +BSON requires that `TextEncoder`, `TextDecoder`, `atob`, `btoa`, and `crypto.getRandomValues` are available globally. These are present in most Javascript runtimes but require polyfilling in React Native. Polyfills for the missing functionality can be installed with the following command: +```sh +npm install --save react-native-get-random-values text-encoding-polyfill base-64 +``` + +The following snippet should be placed at the top of the entrypoint (by default this is the root `index.js` file) for React Native projects using the BSON library.

Conversions are still accurate as we make use of BigInt in the conversion process, but in the case of `unsigned long long` we simply cannot represent some possible output values in JavaScript. For example, converting the JavaScript number `-1` to a Web IDL `unsigned long long` is supposed to produce the Web IDL value `18446744073709551615`. Since we are representing our Web IDL values in JavaScript, we can't represent `18446744073709551615`, so we instead the best we could do is `18446744073709551616` as the output. + +To mitigate this, we could return the raw BigInt value from the conversion function, but right now it is not implemented. If your use case requires such precision, [file an issue](https://github.com/jsdom/webidl-conversions/issues/new). + +On the other hand, `long long` conversion is always accurate, since the input value can never be more precise than the output value. + +### A note on `BufferSource` types + +All of the `BufferSource` types will throw when the relevant `ArrayBuffer` has been detached. This technically is not part of the [specified conversion algorithm](https://heycam.github.io/webidl/#es-buffer-source-types), but instead part of the [getting a reference/getting a copy](https://heycam.github.io/webidl/#ref-for-dfn-get-buffer-source-reference%E2%91%A0) algorithms. We've consolidated them here for convenience and ease of implementation, but if there is a need to separate them in the future, please open an issue so we can investigate. + +## Background + +What's actually going on here, conceptually, is pretty weird. Let's try to explain. + +Web IDL, as part of its madness-inducing design, has its own type system. When people write algorithms in web platform specs, they usually operate on Web IDL values, i.e. instances of Web IDL types. For example, if they were specifying the algorithm for our `doStuff` operation above, they would treat `x` as a Web IDL value of [Web IDL type `boolean`](http://heycam.github.io/webidl/#idl-boolean). Crucially, they would _not_ treat `x` as a JavaScript variable whose value is either the JavaScript `true` or `false`. They're instead working in a different type system altogether, with its own rules. + +Separately from its type system, Web IDL defines a ["binding"](http://heycam.github.io/webidl/#ecmascript-binding) of the type system into JavaScript. This contains rules like: when you pass a JavaScript value to the JavaScript method that manifests a given Web IDL operation, how does that get converted into a Web IDL value? For example, a JavaScript `true` passed in the position of a Web IDL `boolean` argument becomes a Web IDL `true`. But, a JavaScript `true` passed in the position of a [Web IDL `unsigned long`](http://heycam.github.io/webidl/#idl-unsigned-long) becomes a Web IDL `1`. And so on. + +Finally, we have the actual implementation code. This is usually C++, although these days [some smart people are using Rust](https://github.com/servo/servo). The implementation, of course, has its own type system. So when they implement the Web IDL algorithms, they don't actually use Web IDL values, since those aren't "real" outside of specs. Instead, implementations apply the Web IDL binding rules in such a way as to convert incoming JavaScript values into C++ values. For example, if code in the browser called `doStuff(true, true)`, then the implementation code would eventually receive a C++ `bool` containing `true` and a C++ `uint32_t` containing `1`. + +The upside of all this is that implementations can abstract all the conversion logic away, letting Web IDL handle it, and focus on implementing the relevant methods in C++ with values of the correct type already provided. That is payoff of Web IDL, in a nutshell. + +And getting to that payoff is the goal of _this_ project—but for JavaScript implementations, instead of C++ ones. That is, this library is designed to make it easier for JavaScript developers to write functions that behave like a given Web IDL operation. So conceptually, the conversion pipeline, which in its general form is JavaScript values ↦ Web IDL values ↦ implementation-language values, in this case becomes JavaScript values ↦ Web IDL values ↦ JavaScript values. And that intermediate step is where all the logic is performed: a JavaScript `true` becomes a Web IDL `1` in an unsigned long context, which then becomes a JavaScript `1`. + +## Don't use this + +Seriously, why would you ever use this? You really shouldn't. Web IDL is … strange, and you shouldn't be emulating its semantics. If you're looking for a generic argument-processing library, you should find one with better rules than those from Web IDL. In general, your JavaScript should not be trying to become more like Web IDL; if anything, we should fix Web IDL to make it more like JavaScript. + +The _only_ people who should use this are those trying to create faithful implementations (or polyfills) of web platform interfaces defined in Web IDL.

+await client.connect(); +const collection = client.db().collection('collection'); + +try { + await collection.insertOne({ _id: 1 }); + await collection.insertOne({ _id: 1 }); // duplicate key error +} catch (error) { + if (error instanceof MongoServerError) { + console.log(`Error worth logging: ${error}`);

In version 4, this will now overwrite the data at the offset position. To insert data there are now corresponding .insertXXX(value, offset) methods. + +**SmartBuffer v3**: +```javascript +const buff = SmartBuffer.fromBuffer(new Buffer([1,2,3,4,5,6])); +buff.writeInt8(7, 2); +console.log(buff.toBuffer()) + +// +``` + +**SmartBuffer v4**: +```javascript +const buff = SmartBuffer.fromBuffer(new Buffer([1,2,3,4,5,6])); +buff.writeInt8(7, 2); +console.log(buff.toBuffer()); + +// +``` + +To insert you instead should use: +```javascript +const buff = SmartBuffer.fromBuffer(new Buffer([1,2,3,4,5,6])); +buff.insertInt8(7, 2); +console.log(buff.toBuffer()); + +// +``` + +**Note:** Insert/Writing to a position beyond the currently tracked internal Buffer will zero pad to your offset. + +## Constructing a smart-buffer + +There are a few different ways to construct a SmartBuffer instance. + +```javascript +// Creating SmartBuffer from existing Buffer +const buff = SmartBuffer.fromBuffer(buffer); // Creates instance from buffer. (Uses default utf8 encoding) +const buff = SmartBuffer.fromBuffer(buffer, 'ascii'); // Creates instance from buffer with ascii encoding for strings. + +// Creating SmartBuffer with specified internal Buffer size.

It however does not function correctly if you're mixing both read and write operations with each other. + +## Breaking Changes with 2.0 +The latest version (2.0+) is written in TypeScript, and are compiled to ES6 Javascript. This means the earliest Node.js it supports will be 4.x (in strict mode.) If you're using version 6 and above it will work without any issues. From an API standpoint, 2.0 is backwards compatible. The only difference is SmartBuffer is not exported directly as the root module. + +## Breaking Changes with 3.0 +Starting with 3.0, if any of the readIntXXXX() methods are called and the requested data is larger than the bounds of the internally managed valid buffer data, an exception will now be thrown. + +## Installing: + +`npm install smart-buffer` + +or + +`yarn add smart-buffer` + +Note: The published NPM package includes the built javascript library. +If you cloned this repo and wish to build the library manually use: + +`tsc -p ./` + +## Using smart-buffer + +### Example + +Say you were building a packet that had to conform to the following protocol: + +`[PacketType:2][PacketLength:2][Data:XX]` + +To build this packet using the vanilla Buffer class, you would have to count up the length of the data payload beforehand. You would also need to keep track of the current "cursor" position in your Buffer so you write everything in the right places. With smart-buffer you don't have to do either of those things. + +```javascript +// 1.x (javascript) +var SmartBuffer = require('smart-buffer'); + +// 1.x (typescript) +import SmartBuffer = require('smart-buffer'); + +// 2.x+ (javascript) +const SmartBuffer = require('smart-buffer').SmartBuffer; + +// 2.x+ (typescript) +import { SmartBuffer, SmartBufferOptions} from 'smart-buffer'; + +function createLoginPacket(username, password, age, country) { + let packet = new SmartBuffer(); + packet.writeUInt16LE(0x0060); // Login Packet Type/ID + packet.writeStringNT(username); + packet.writeStringNT(password); + packet.writeUInt8(age); + packet.writeStringNT(country); + packet.writeUInt16LE(packet.length - 2, 2); + + return packet.toBuffer(); +} +``` +With the above function, you now can do this: +```javascript +let login = createLoginPacket("Josh", "secret123", 22, "United States"); + +// +``` +Notice that the `[PacketLength:2]` part of the packet was inserted after we had added everything else, and as shown in the Buffer dump above, is in the correct location along with everything else. + +Reading back the packet we created above is just as easy: +```javascript + +let reader = SmartBuffer.fromBuffer(login); + +let logininfo = { + packetType: reader.readUInt16LE(), + packetLength: reader.readUInt16LE(), + username: reader.readStringNT(), + password: reader.readStringNT(), + age: reader.readUInt8(), + country: reader.readStringNT() +}; + +/* +{ + packetType: 96, (0x0060) + packetLength: 30, + username: 'Josh', + password: 'secret123', + age: 22, + country: 'United States' +}; +*/ +``` + +# Api Reference: + +### Constructing a smart-buffer + +smart-buffer has a few different ways to construct an instance. Starting with version 2.0, the following factory methods are preffered. + +```javascript +let SmartBuffer = require('smart-buffer'); + +// Creating SmartBuffer from existing Buffer +let buff = SmartBuffer.fromBuffer(buffer); // Creates instance from buffer. (Uses default utf8 encoding) +let buff = SmartBuffer.fromBuffer(buffer, 'ascii'); // Creates instance from buffer with ascii encoding for Strings. + +// Creating SmartBuffer with specified internal Buffer size. +let buff = SmartBuffer.fromSize(1024); // Creates instance with internal Buffer size of 1024. +let buff = SmartBuffer.fromSize(1024, 'utf8'); // Creates instance with intenral Buffer size of 1024, and utf8 encoding. + +// Creating SmartBuffer with options object. This one specifies size and encoding. +let buff = SmartBuffer.fromOptions({ + size: 1024, + encoding: 'ascii' +}); + +// Creating SmartBuffer with options object. This one specified an existing Buffer. +let buff = SmartBuffer.fromOptions({ + buff: buffer +}); + +// Just want a regular SmartBuffer with all default options? +let buff = new SmartBuffer(); +``` + +## Backwards Compatibility: + +All constructors used prior to 2.0 still are supported. However it's not recommended to use these. + +```javascript +let writer = new SmartBuffer(); // Defaults to utf8, 4096 length internal Buffer. +let writer = new SmartBuffer(1024); // Defaults to utf8, 1024 length internal Buffer. +let writer = new SmartBuffer('ascii'); // Sets to ascii encoding, 4096 length internal buffer. +let writer = new SmartBuffer(1024, 'ascii'); // Sets to ascii encoding, 1024 length internal buffer. +``` + +## Reading Data + +smart-buffer supports all of the common read functions you will find in the vanilla Buffer class.

You can specify a offset/position to **insert** the given value at, but keep in mind this does not override data at the given position.

+#### `bits.set(index, value)` + +Set a bit to true or false. + +#### `bits.get(index)` + +Get the value of a bit. + +#### `bits.pages` + +A [memory-pager](https://github.com/mafintosh/memory-pager) instance that is managing the underlying memory. +If you set `trackUpdates` to true in the constructor you can use `.lastUpdate()` on this instance to get the last updated memory page. + +#### `var buffer = bits.toBuffer()` + +Get a single buffer representing the entire bitfield. + +## License + +MIT diff --git a/2_PAC/node_modules/sparse-bitfield/index.js
