If I recall correctly, 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. - - -## License - -MIT © [Sindre Sorhus](http://sindresorhus.com) diff --git a/pages/students/2016/jan_holp/dp2021/dp2021 zdrojove subory/node_modules/ansi-styles/index.js b/pages/students/2016/jan_holp/dp2021/dp2021 zdrojove subory/node_modules/ansi-styles/index.js deleted file mode 100644 index 78945278..00000000 --- a/pages/students/2016/jan_holp/dp2021/dp2021 zdrojove subory/node_modules/ansi-styles/index.js +++ /dev/null @@ -1,65 +0,0 @@ -'use strict'; - -function assembleStyles () { - var styles = { - modifiers: { - reset: [0, 0], - bold: [1, 22], // 21 isn't widely supported and 22 does the same thing - dim: [2, 22], - italic: [3, 23], - underline: [4, 24], - inverse: [7, 27], - hidden: [8, 28], - strikethrough: [9, 29] - }, - colors: { - black: [30, 39], - red: [31, 39], - green: [32, 39], - yellow: [33, 39], - blue: [34, 39], - magenta: [35, 39], - cyan: [36, 39], - white: [37, 39], - gray: [90, 39] - }, - bgColors: { - bgBlack: [40, 49], - bgRed: [41, 49], - bgGreen: [42, 49], - bgYellow: [43, 49], - bgBlue: [44, 49], - bgMagenta: [45, 49], - bgCyan: [46, 49], - bgWhite: [47, 49] - } - }; - - // fix humans - styles.colors.grey = styles.colors.gray; - - Object.keys(styles).forEach(function (groupName) { - var group = styles[groupName]; - - Object.keys(group).forEach(function (styleName) { - var style = group[styleName]; - - styles[styleName] = group[styleName] = { - open: '\u001b[' + style[0] + 'm', - close: '\u001b[' + style[1] + 'm' - }; - }); - - Object.defineProperty(styles, groupName, { - value: group, - enumerable: false - }); - }); - - return styles; -} - -Object.defineProperty(module, 'exports', { - enumerable: true, - get: assembleStyles -}); diff --git a/pages/students/2016/jan_holp/dp2021/dp2021 zdrojove subory/node_modules/ansi-styles/license b/pages/students/2016/jan_holp/dp2021/dp2021 zdrojove subory/node_modules/ansi-styles/license deleted file mode 100644 index 654d0bfe..00000000 --- a/pages/students/2016/jan_holp/dp2021/dp2021 zdrojove subory/node_modules/ansi-styles/license +++ /dev/null @@ -1,21 +0,0 @@ -The MIT License (MIT) - -Copyright (c) Sindre Sorhus (sindresorhus.com) - -Permission is hereby granted, free of charge, to any person obtaining a copy -of this software and associated documentation files (the "Software"), to deal -in the Software without restriction, including without limitation the rights -to use, copy, modify, merge, publish, distribute, sublicense, and/or sell -copies of the Software, and to permit persons to whom the Software is -furnished to do so, subject to the following conditions: - -The above copyright notice and this permission notice shall be included in -all copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, -FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

All -middlewares will populate the `req.body` property with the parsed body when -the `Content-Type` request header matches the `type` option, or an empty -object (`{}`) if there was no body to parse, the `Content-Type` was not matched, -or an error occurred. - -The various errors returned by this module are described in the -[errors section](#errors). - -### bodyParser.json([options]) - -Returns middleware that only parses `json` and only looks at requests where -the `Content-Type` header matches the `type` option. This parser accepts any -Unicode encoding of the body and supports automatic inflation of `gzip` and -`deflate` encodings. - -A new `body` object containing the parsed data is populated on the `request` -object after the middleware (i.e. `req.body`). - -#### Options - -The `json` function takes an optional `options` object that may contain any of -the following keys: - -##### inflate - -When set to `true`, then deflated (compressed) bodies will be inflated; when -`false`, deflated bodies are rejected. Defaults to `true`. - -##### limit - -Controls the maximum request body size. If this is a number, then the value -specifies the number of bytes; if it is a string, the value is passed to the -[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults -to `'100kb'`. - -##### reviver - -The `reviver` option is passed directly to `JSON.parse` as the second -argument. You can find more information on this argument -[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter). - -##### strict - -When set to `true`, will only accept arrays and objects; when `false` will -accept anything `JSON.parse` accepts. Defaults to `true`. - -##### type - -The `type` option is used to determine what media type the middleware will -parse. This option can be a string, array of strings, or a function. If not a -function, `type` option is passed directly to the -[type-is](https://www.npmjs.org/package/type-is#readme) library and this can -be an extension name (like `json`), a mime type (like `application/json`), or -a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type` -option is called as `fn(req)` and the request is parsed if it returns a truthy -value. Defaults to `application/json`. - -##### verify - -The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, -where `buf` is a `Buffer` of the raw request body and `encoding` is the -encoding of the request.

If a function, the `type` option is called as `fn(req)` -and the request is parsed if it returns a truthy value. Defaults to -`application/octet-stream`. - -##### verify - -The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, -where `buf` is a `Buffer` of the raw request body and `encoding` is the -encoding of the request. The parsing can be aborted by throwing an error. - -### bodyParser.text([options]) - -Returns middleware that parses all bodies as a string and only looks at -requests where the `Content-Type` header matches the `type` option. This -parser supports automatic inflation of `gzip` and `deflate` encodings. - -A new `body` string containing the parsed data is populated on the `request` -object after the middleware (i.e. `req.body`). This will be a string of the -body. - -#### Options - -The `text` function takes an optional `options` object that may contain any of -the following keys: - -##### defaultCharset - -Specify the default character set for the text content if the charset is not -specified in the `Content-Type` header of the request. Defaults to `utf-8`. - -##### inflate - -When set to `true`, then deflated (compressed) bodies will be inflated; when -`false`, deflated bodies are rejected.

The parsing can be aborted by throwing an error. - -### bodyParser.urlencoded([options]) - -Returns middleware that only parses `urlencoded` bodies and only looks at -requests where the `Content-Type` header matches the `type` option. This -parser accepts only UTF-8 encoding of the body and supports automatic -inflation of `gzip` and `deflate` encodings. - -A new `body` object containing the parsed data is populated on the `request` -object after the middleware (i.e. `req.body`). This object will contain -key-value pairs, where the value can be a string or array (when `extended` is -`false`), or any type (when `extended` is `true`). - -#### Options - -The `urlencoded` function takes an optional `options` object that may contain -any of the following keys: - -##### extended - -The `extended` option allows to choose between parsing the URL-encoded data -with the `querystring` library (when `false`) or the `qs` library (when -`true`). The "extended" syntax allows for rich objects and arrays to be -encoded into the URL-encoded format, allowing for a JSON-like experience -with URL-encoded. For more information, please -[see the qs library](https://www.npmjs.org/package/qs#readme). - -Defaults to `true`, but using the default has been deprecated. Please -research into the difference between `qs` and `querystring` and choose the -appropriate setting. - -##### inflate - -When set to `true`, then deflated (compressed) bodies will be inflated; when -`false`, deflated bodies are rejected. Defaults to `true`. - -##### limit - -Controls the maximum request body size. If this is a number, then the value -specifies the number of bytes; if it is a string, the value is passed to the -[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults -to `'100kb'`. - -##### parameterLimit - -The `parameterLimit` option controls the maximum number of parameters that -are allowed in the URL-encoded data. If a request contains more parameters -than this value, a 413 will be returned to the client. Defaults to `1000`. - -##### type - -The `type` option is used to determine what media type the middleware will -parse. This option can be a string, array of strings, or a function. If not -a function, `type` option is passed directly to the -[type-is](https://www.npmjs.org/package/type-is#readme) library and this can -be an extension name (like `urlencoded`), a mime type (like -`application/x-www-form-urlencoded`), or a mime type with a wildcard (like -`*/x-www-form-urlencoded`). If a function, the `type` option is called as -`fn(req)` and the request is parsed if it returns a truthy value. Defaults -to `application/x-www-form-urlencoded`. - -##### verify - -The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, -where `buf` is a `Buffer` of the raw request body and `encoding` is the -encoding of the request. The parsing can be aborted by throwing an error. - -## Errors - -The middlewares provided by this module create errors depending on the error -condition during parsing. The errors will typically have a `status`/`statusCode` -property that contains the suggested HTTP response code, an `expose` property -to determine if the `message` property should be displayed to the client, a -`type` property to determine the type of error without matching against the -`message`, and a `body` property containing the read body, if available. - -The following are the common errors emitted, though any error can come through -for various reasons. - -### content encoding unsupported - -This error will occur when the request had a `Content-Encoding` header that -contained an encoding but the "inflation" option was set to `false`. The -`status` property is set to `415`, the `type` property is set to -`'encoding.unsupported'`, and the `charset` property will be set to the -encoding that is unsupported. - -### request aborted - -This error will occur when the request is aborted by the client before reading -the body has finished. The `received` property will be set to the number of -bytes received before the request was aborted and the `expected` property is -set to the number of expected bytes. The `status` property is set to `400` -and `type` property is set to `'request.aborted'`. - -### request entity too large - -This error will occur when the request body's size is larger than the "limit" -option. The `limit` property will be set to the byte limit and the `length` -property will be set to the request body's length. The `status` property is -set to `413` and the `type` property is set to `'entity.too.large'`. - -### request size did not match content length - -This error will occur when the request's length did not match the length from -the `Content-Length` header. This typically occurs when the request is malformed, -typically when the `Content-Length` header was calculated based on characters -instead of bytes. The `status` property is set to `400` and the `type` property -is set to `'request.size.invalid'`. - -### stream encoding should not be set - -This error will occur when something called the `req.setEncoding` method prior -to this middleware. This module operates directly on bytes only and you cannot -call `req.setEncoding` when using this module. The `status` property is set to -`500` and the `type` property is set to `'stream.encoding.set'`. - -### too many parameters - -This error will occur when the content of the request exceeds the configured -`parameterLimit` for the `urlencoded` parser. The `status` property is set to -`413` and the `type` property is set to `'parameters.too.many'`. - -### unsupported charset "BOGUS" - -This error will occur when the request had a charset parameter in the -`Content-Type` header, but the `iconv-lite` module does not support it OR the -parser does not support it. The charset is contained in the message as well -as in the `charset` property. The `status` property is set to `415`, the -`type` property is set to `'charset.unsupported'`, and the `charset` property -is set to the charset that is unsupported. - -### unsupported content encoding "bogus" - -This error will occur when the request had a `Content-Encoding` header that -contained an unsupported encoding. The encoding is contained in the message -as well as in the `encoding` property. The `status` property is set to `415`, -the `type` property is set to `'encoding.unsupported'`, and the `encoding` -property is set to the encoding that is unsupported. - -## Examples - -### Express/Connect top-level generic - -This example demonstrates adding a generic JSON and URL-encoded parser as a -top-level middleware, which will parse the bodies of all incoming requests. -This is the simplest setup. - -```js -var express = require('express') -var bodyParser = require('body-parser') - -var app = express() - -// parse application/x-www-form-urlencoded -app.use(bodyParser.urlencoded({ extended: false })) - -// parse application/json -app.use(bodyParser.json()) - -app.use(function (req, res) { - res.setHeader('Content-Type', 'text/plain') - res.write('you posted:\n') - res.end(JSON.stringify(req.body, null, 2)) -}) -``` - -### Express route-specific - -This example demonstrates adding body parsers specifically to the routes that -need them. In general, this is the most recommended way to use body-parser with -Express. - -```js -var express = require('express') -var bodyParser = require('body-parser') - -var app = express() - -// create application/json parser -var jsonParser = bodyParser.json() - -// create application/x-www-form-urlencoded parser -var urlencodedParser = bodyParser.urlencoded({ extended: false }) - -// POST /login gets urlencoded bodies -app.post('/login', urlencodedParser, function (req, res) { - res.send('welcome, ' + req.body.username) -}) - -// POST /api/users gets JSON bodies -app.post('/api/users', jsonParser, function (req, res) { - // create user in req.body -}) -``` - -### Change accepted type for parsers - -All the parsers accept a `type` option which allows you to change the -`Content-Type` that the middleware will parse. - -```js -var express = require('express') -var bodyParser = require('body-parser') - -var app = express() - -// parse various different custom JSON types as JSON -app.use(bodyParser.json({ type: 'application/*+json' })) - -// parse some custom thing into a Buffer -app.use(bodyParser.raw({ type: 'application/vnd.custom-type' })) - -// parse an HTML body into a string -app.use(bodyParser.text({ type: 'text/html' })) -``` - -## License - -[MIT](LICENSE) - -[npm-image]: https://img.shields.io/npm/v/body-parser.svg -[npm-url]: https://npmjs.org/package/body-parser -[travis-image]: https://img.shields.io/travis/expressjs/body-parser/master.svg -[travis-url]: https://travis-ci.org/expressjs/body-parser -[coveralls-image]: https://img.shields.io/coveralls/expressjs/body-parser/master.svg -[coveralls-url]: https://coveralls.io/r/expressjs/body-parser?branch=master -[downloads-image]: https://img.shields.io/npm/dm/body-parser.svg -[downloads-url]: https://npmjs.org/package/body-parser diff --git a/pages/students/2016/jan_holp/dp2021/dp2021 zdrojove subory/node_modules/body-parser/index.js b/pages/students/2016/jan_holp/dp2021/dp2021 zdrojove subory/node_modules/body-parser/index.js deleted file mode 100644 index 93c3a1ff..00000000 --- a/pages/students/2016/jan_holp/dp2021/dp2021 zdrojove subory/node_modules/body-parser/index.js +++ /dev/null @@ -1,157 +0,0 @@ -/*! -

WHERE key=?'; -const params = [ new Date(1942, 10, 1), 'jimi-hendrix' ]; - -// Set the prepare flag in the query options -await client.execute(query, params, { prepare: true }); -console.log('Row updated on the cluster'); -``` - -### Row streaming and pipes - -When using `#eachRow()` and `#stream()` methods, the driver parses each row as soon as it is received, - yielding rows without buffering them. - -```javascript -// Reducing a large result -client.eachRow( - 'SELECT time, val FROM temperature WHERE station_id=', - ['abc'], - (n, row) => { - // The callback will be invoked per each row as soon as they are received - minTemperature = Math.min(row.val, minTemperature); - }, - err => { - // This function will be invoked when all rows where consumed or an error was encountered - } -); -``` - -The `#stream()` method works in the same way but instead of callback it returns a [Readable Streams2][streams2] object - in `objectMode` that emits instances of `Row`. - -It can be **piped** downstream and provides automatic pause/resume logic (it buffers when not read). - -```javascript -client.stream('SELECT time, val FROM temperature WHERE station_id=', [ 'abc' ]) - .on('readable', function () { - // 'readable' is emitted as soon a row is received and parsed - let row; - while (row = this.read()) { - console.log('time %s and value %s', row.time, row.val); - } - }) - .on('end', function () { - // Stream ended, there aren't any more rows - }) - .on('error', function (err) { - // Something went wrong: err is a response error from Cassandra - }); -``` - -### User defined types - -[User defined types (UDT)][cql-udt] are represented as JavaScript objects. - -For example: -Consider the following UDT and table - -```cql -CREATE TYPE address ( - street text, - city text, - state text, - zip int, - phones set -); -CREATE TABLE users ( - name text PRIMARY KEY, - email text, - address frozen

You can also use `eachRow()` -method to retrieve the following pages by using `autoPage` flag. See [paging documentation for more -information][doc-paging]. - -### Batch multiple statements - -You can execute multiple statements in a batch to update/insert several rows atomically even in different column families. - -```javascript -const queries = [ - { - query: 'UPDATE user_profiles SET email=?

Check the documentation on working with - [numerical values][doc-numerical], [uuids][doc-uuid] and [collections][doc-collections]. - -## Logging - -Instances of `Client()` are `EventEmitter` and emit `log` events: - -```javascript -client.on('log', (level, loggerName, message, furtherInfo) => { - console.log(`${level} - ${loggerName}: ${message}`); -}); -``` - -The `level` being passed to the listener can be `verbose`, `info`, `warning` or `error`.

While the driver provides lots of extensibility points and configurability, few client options are required.

- *

Default values for all settings are designed to be suitable for the majority of use cases, you should avoid - * fine tuning it when not needed.

- *

See [Client constructor]{@link Client} documentation for recommended options.

- * @typedef {Object} ClientOptions - * @property {Array.} contactPoints - * Array of addresses or host names of the nodes to add as contact points. - *

- * Contact points are addresses of Cassandra nodes that the driver uses to discover the cluster topology. - *

- *

- * Only one contact point is required (the driver will retrieve the address of the other nodes automatically), - * but it is usually a good idea to provide more than one contact point, because if that single contact point is - * unavailable, the driver will not be able to initialize correctly. - *

- * @property {String} [localDataCenter] The local data center to use. - *

- * If using DCAwareRoundRobinPolicy (default), this option is required and only hosts from this data center are - * connected to and used in query plans. - *

- * @property {String} [keyspace] The logged keyspace for all the connections created within the {@link Client} instance. - * @property {Object} [credentials] An object containing the username and password for plain-text authentication. - * It configures the authentication provider to be used against Apache Cassandra's PasswordAuthenticator or DSE's - * DseAuthenticator, when default auth scheme is plain-text. - *

- * Note that you should configure either credentials or authProvider to connect to an - * auth-enabled cluster, but not both. - *

- * @property {String} [credentials.username] The username to use for plain-text authentication. - * @property {String} [credentials.password] The password to use for plain-text authentication. - * @property {Uuid} [id] A unique identifier assigned to a {@link Client} object, that will be communicated to the - * server (DSE 6.0+) to identify the client instance created with this options. When not defined, the driver will - * generate a random identifier. - * @property {String} [applicationName] An optional setting identifying the name of the application using - * the {@link Client} instance. - *

This value is passed to DSE and is useful as metadata for describing a client connection on the server side.

- * @property {String} [applicationVersion] An optional setting identifying the version of the application using - * the {@link Client} instance. - *

This value is passed to DSE and is useful as metadata for describing a client connection on the server side.

- * @property {Object} [monitorReporting] Options for reporting mechanism from the client to the DSE server, for - * versions that support it. - * @property {Boolean} [monitorReporting.enabled=true] Determines whether the reporting mechanism is enabled. - * Defaults to true. - * @property {Object} [cloud] The options to connect to a cloud instance. - * @property {String|URL} cloud.secureConnectBundle Determines the file path for the credentials file bundle. - * @property {Number} [refreshSchemaDelay] The default window size in milliseconds used to debounce node list and schema - * refresh metadata requests. Default: 1000. - * @property {Boolean} [isMetadataSyncEnabled] Determines whether client-side schema metadata retrieval and update is - * enabled. - *

Setting this value to false will cause keyspace information not to be automatically loaded, affecting - * replica calculation per token in the different keyspaces. When disabling metadata synchronization, use - * [Metadata.refreshKeyspaces()]{@link module:metadata~Metadata#refreshKeyspaces} to keep keyspace information up to - * date or token-awareness will not work correctly.

- * Default: true. - * @property {Boolean} [prepareOnAllHosts] Determines if the driver should prepare queries on all hosts in the cluster. - * Default: true. - * @property {Boolean} [rePrepareOnUp] Determines if the driver should re-prepare all cached prepared queries on a - * host when it marks it back up. - * Default: true. - * @property {Number} [maxPrepared] Determines the maximum amount of different prepared queries before evicting items - * from the internal cache. Reaching a high threshold hints that the queries are not being reused, like when - * hard-coding parameter values inside the queries. - * Default: 500. - * @property {Object} [policies] - * @property {LoadBalancingPolicy} [policies.loadBalancing] The load balancing policy instance to be used to determine - * the coordinator per query. - * @property {RetryPolicy} [policies.retry] The retry policy. - * @property {ReconnectionPolicy} [policies.reconnection] The reconnection policy to be used. - * @property {AddressTranslator} [policies.addressResolution] The address resolution policy. - * @property {SpeculativeExecutionPolicy} [policies.speculativeExecution] The SpeculativeExecutionPolicy - * instance to be used to determine if the client should send speculative queries when the selected host takes more - * time than expected. - *

- * Default: [NoSpeculativeExecutionPolicy]{@link - * module:policies/speculativeExecution~NoSpeculativeExecutionPolicy} - *

- * @property {TimestampGenerator} [policies.timestampGeneration] The client-side - * [query timestamp generator]{@link module:policies/timestampGeneration~TimestampGenerator}. - *

- * Default: [MonotonicTimestampGenerator]{@link module:policies/timestampGeneration~MonotonicTimestampGenerator} - * - *

- *

Use null to disable client-side timestamp generation.

- * @property {QueryOptions} [queryOptions] Default options for all queries. - * @property {Object} [pooling] Pooling options. - * @property {Number} [pooling.heartBeatInterval] The amount of idle time in milliseconds that has to pass before the - * driver issues a request on an active connection to avoid idle time disconnections. Default: 30000. - * @property {Object} [pooling.coreConnectionsPerHost] Associative array containing amount of connections per host - * distance. - * @property {Number} [pooling.maxRequestsPerConnection] The maximum number of requests per connection. The default - * value is: - *
    - *
  • For modern protocol versions (v3 and above): 2048
    • - *
  • For older protocol versions (v1 and v2): 128
    • - *
- * @property {Boolean} [pooling.warmup] Determines if all connections to hosts in the local datacenter must be opened on - * connect. Default: true. - * @property {Object} [protocolOptions] - * @property {Number} [protocolOptions.port] The port to use to connect to the Cassandra host. If not set through this - * method, the default port (9042) will be used instead. - * @property {Number} [protocolOptions.maxSchemaAgreementWaitSeconds] The maximum time in seconds to wait for schema - * agreement between nodes before returning from a DDL query. Default: 10. - * @property {Number} [protocolOptions.maxVersion] When set, it limits the maximum protocol version used to connect to - * the nodes. - * Useful for using the driver against a cluster that contains nodes with different major/minor versions of Cassandra. - * @property {Boolean} [protocolOptions.noCompact] When set to true, enables the NO_COMPACT startup option. - *

- * When this option is supplied SELECT, UPDATE, DELETE, and BATCH - * statements on COMPACT STORAGE tables function in "compatibility" mode which allows seeing these tables - * as if they were "regular" CQL tables. - *

- *

- * This option only effects interactions with interactions with tables using COMPACT STORAGE and is only - * supported by C* 3.0.16+, 3.11.2+, 4.0+ and DSE 6.0+. - *

- * @property {Object} [socketOptions] - * @property {Number} [socketOptions.connectTimeout] Connection timeout in milliseconds. Default: 5000. - * @property {Number} [socketOptions.defunctReadTimeoutThreshold] Determines the amount of requests that simultaneously - * have to timeout before closing the connection. Default: 64. - * @property {Boolean} [socketOptions.keepAlive] Whether to enable TCP keep-alive on the socket. Default: true. - * @property {Number} [socketOptions.keepAliveDelay] TCP keep-alive delay in milliseconds. Default: 0. - * @property {Number} [socketOptions.readTimeout] Per-host read timeout in milliseconds. - *

- * Please note that this is not the maximum time a call to {@link Client#execute} may have to wait; - * this is the maximum time that call will wait for one particular Cassandra host, but other hosts will be tried if - * one of them timeout. In other words, a {@link Client#execute} call may theoretically wait up to - * readTimeout * number_of_cassandra_hosts (though the total number of hosts tried for a given query also - * depends on the LoadBalancingPolicy in use). - *

When setting this value, keep in mind the following:

- *
    - *
  • the timeout settings used on the Cassandra side (*_request_timeout_in_ms in cassandra.yaml) should be taken - * into account when picking a value for this read timeout. You should pick a value a couple of seconds greater than - * the Cassandra timeout settings. - *
    • - *
  • - * the read timeout is only approximate and only control the timeout to one Cassandra host, not the full query. - *
    • - *
- * Setting a value of 0 disables read timeouts. Default: 12000. - * @property {Boolean} [socketOptions.tcpNoDelay] When set to true, it disables the Nagle algorithm. Default: true. - * @property {Number} [socketOptions.coalescingThreshold] Buffer length in bytes use by the write queue before flushing - * the frames. Default: 8000. - * @property {AuthProvider} [authProvider] Provider to be used to authenticate to an auth-enabled cluster. - * @property {RequestTracker} [requestTracker] The instance of RequestTracker used to monitor or log requests executed - * with this instance. - * @property {Object} [sslOptions] Client-to-node ssl options. When set the driver will use the secure layer. - * You can specify cert, ca, ... options named after the Node.js tls.connect() options. - *

- * It uses the same default values as Node.js tls.connect() except for rejectUnauthorized - * which is set to false by default (for historical reasons). This setting is likely to change - * in upcoming versions to enable validation by default. - *

- * @property {Object} [encoding] Encoding options. - * @property {Function} [encoding.map] Map constructor to use for Cassandra map type encoding and decoding. - * If not set, it will default to Javascript Object with map keys as property names. - * @property {Function} [encoding.set] Set constructor to use for Cassandra set type encoding and decoding. - * If not set, it will default to Javascript Array. - * @property {Boolean} [encoding.copyBuffer] Determines if the network buffer should be copied for buffer based data - * types (blob, uuid, timeuuid and inet). - *

- * Setting it to true will cause that the network buffer is copied for each row value of those types, - * causing additional allocations but freeing the network buffer to be reused. - * Setting it to true is a good choice for cases where the Row and ResultSet returned by the queries are long-lived - * objects. - *

- *

- * Setting it to false will cause less overhead and the reference of the network buffer to be maintained until the row - * / result set are de-referenced. - * Default: true. - *

- * @property {Boolean} [encoding.useUndefinedAsUnset] Valid for Cassandra 2.2 and above. Determines that, if a parameter - * is set to - * undefined it should be encoded as unset. - *

- * By default, ECMAScript undefined is encoded as null in the driver. Cassandra 2.2 - * introduced the concept of unset. - * At driver level, you can set a parameter to unset using the field types.unset. Setting this flag to - * true allows you to use ECMAScript undefined as Cassandra unset. - *

- *

- * Default: true. - *

- * @property {Boolean} [encoding.useBigIntAsLong] Use [BigInt ECMAScript type](https://tc39.github.io/proposal-bigint/) - * to represent CQL bigint and counter data types. - * @property {Boolean} [encoding.useBigIntAsVarint] Use [BigInt ECMAScript - * type](https://tc39.github.io/proposal-bigint/) to represent CQL varint data type. - * @property {Array.} [profiles] The array of [execution profiles]{@link ExecutionProfile}. - * @property {Function} [promiseFactory] Function to be used to create a Promise from a - * callback-style function. - *

- * Promise libraries often provide different methods to create a promise. For example, you can use Bluebird's - * Promise.fromCallback() method. - *

- *

- * By default, the driver will use the - * [Promise constructor]{@link https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Promise}. - *

- */ - -/** - * Query options - * @typedef {Object} QueryOptions - * @property {Boolean} [autoPage] Determines if the driver must retrieve the following result pages automatically. - *

- * This setting is only considered by the [Client#eachRow()]{@link Client#eachRow} method. For more information, - * check the - * [paging results documentation]{@link https://docs.datastax.com/en/developer/nodejs-driver/latest/features/paging/}. - *

- * @property {Boolean} [captureStackTrace] Determines if the stack trace before the query execution should be - * maintained. - *

- * Useful for debugging purposes, it should be set to false under production environment as it adds an - * unnecessary overhead to each execution. - *

- * Default: false. - * @property {Number} [consistency] [Consistency level]{@link module:types~consistencies}. - *

- * Defaults to localOne for Apache Cassandra and DSE deployments. - * For DataStax Astra, it defaults to localQuorum. - *

- * @property {Object} [customPayload] Key-value payload to be passed to the server. On the Cassandra side, - * implementations of QueryHandler can use this data. - * @property {String} [executeAs] The user or role name to act as when executing this statement. - *

When set, it executes as a different user/role than the one currently authenticated (a.k.a. proxy execution).

- *

This feature is only available in DSE 5.1+.

- * @property {String|ExecutionProfile} [executionProfile] Name or instance of the [profile]{@link ExecutionProfile} to - * be used for this execution. If not set, it will the use "default" execution profile. - * @property {Number} [fetchSize] Amount of rows to retrieve per page. - * @property {Array|Array} [hints] Type hints for parameters given in the query, ordered as for the parameters. - *

For batch queries, an array of such arrays, ordered as with the queries in the batch.

- * @property {Host} [host] The host that should handle the query. - *

- * Use of this option is heavily discouraged and should only be used in the following cases: - *

- *
    - *
  1. - * Querying node-local tables, such as tables in the system and system_views - * keyspaces. - *
    2. - *
  2. - * Applying a series of schema changes, where it may be advantageous to execute schema changes in sequence on the - * same node. - *
    3. - *
- *

- * Configuring a specific host causes the configured - * [LoadBalancingPolicy]{@link module:policies/loadBalancing~LoadBalancingPolicy} to be completely bypassed. - * However, if the load balancing policy dictates that the host is at a - * [distance of ignored]{@link module:types~distance} or there is no active connectivity to the host, the request will - * fail with a [NoHostAvailableError]{@link module:errors~NoHostAvailableError}. - *

- * @property {Boolean} [isIdempotent] Defines whether the query can be applied multiple times without changing the result - * beyond the initial application. - *

- * The query execution idempotence can be used at [RetryPolicy]{@link module:policies/retry~RetryPolicy} level to - * determine if an statement can be retried in case of request error or write timeout. - *

- *

Default: false.

- * @property {String} [keyspace] Specifies the keyspace for the query. It is used for the following: - *
    - *
  1. To indicate what keyspace the statement is applicable to (protocol V5+ only). This is useful when the - * query does not provide an explicit keyspace and you want to override the current {@link Client#keyspace}.
    2. - *
  2. For query routing when the query operates on a different keyspace than the current {@link Client#keyspace}.
    3. - *
- * @property {Boolean} [logged] Determines if the batch should be written to the batchlog. Only valid for - * [Client#batch()]{@link Client#batch}, it will be ignored by other methods. Default: true. - * @property {Boolean} [counter] Determines if its a counter batch. Only valid for - * [Client#batch()]{@link Client#batch}, it will be ignored by other methods. Default: false. - * @property {Buffer|String} [pageState] Buffer or string token representing the paging state. - *

Useful for manual paging, if provided, the query will be executed starting from a given paging state.

- * @property {Boolean} [prepare] Determines if the query must be executed as a prepared statement. - * @property {Number} [readTimeout] When defined, it overrides the default read timeout - * (socketOptions.readTimeout) in milliseconds for this execution per coordinator. - *

- * Suitable for statements for which the coordinator may allow a longer server-side timeout, for example aggregation - * queries. - *

- *

- * A value of 0 disables client side read timeout for the execution. Default: undefined. - *

- * @property {RetryPolicy} [retry] Retry policy for the query. - *

- * This property can be used to specify a different [retry policy]{@link module:policies/retry} to the one specified - * in the {@link ClientOptions}.policies. - *

- * @property {Array} [routingIndexes] Index of the parameters that are part of the partition key to determine - * the routing. - * @property {Buffer|Array} [routingKey] Partition key(s) to determine which coordinator should be used for the query. - * @property {Array} [routingNames] Array of the parameters names that are part of the partition key to determine the - * routing. Only valid for non-prepared requests, it's recommended that you use the prepare flag instead. - * @property {Number} [serialConsistency] Serial consistency is the consistency level for the serial phase of - * conditional updates. - * This option will be ignored for anything else that a conditional update/insert. - * @property {Number|Long} [timestamp] The default timestamp for the query in microseconds from the unix epoch - * (00:00:00, January 1st, 1970). - *

If provided, this will replace the server side assigned timestamp as default timestamp.

- *

Use [generateTimestamp()]{@link module:types~generateTimestamp} utility method to generate a valid timestamp - * based on a Date and microseconds parts.

- * @property {Boolean} [traceQuery] Enable query tracing for the execution. Use query tracing to diagnose performance - * problems related to query executions. Default: false. - *

To retrieve trace, you can call [Metadata.getTrace()]{@link module:metadata~Metadata#getTrace} method.

- * @property {Object} [graphOptions] Default options for graph query executions. - *

- * These options are meant to provide defaults for all graph query executions. Consider using - * [execution profiles]{@link ExecutionProfile} if you plan to reuse different set of options across different - * query executions. - *

- * @property {String} [graphOptions.language] The graph language to use in graph queries. Default: - * 'gremlin-groovy'. - * @property {String} [graphOptions.name] The graph name to be used in all graph queries. - *

- * This property is required but there is no default value for it. This value can be overridden at query level. - *

- * @property {Number} [graphOptions.readConsistency] Overrides the - * [consistency level]{@link module:types~consistencies} - * defined in the query options for graph read queries. - * @property {Number} [graphOptions.readTimeout] Overrides the default per-host read timeout (in milliseconds) for all - * graph queries. Default: 0. - *

- * Use null to reset the value and use the default on socketOptions.readTimeout . - *

- * @property {String} [graphOptions.source] The graph traversal source name to use in graph queries. Default: - * 'g'. - * @property {Number} [graphOptions.writeConsistency] Overrides the [consistency - * level]{@link module:types~consistencies} defined in the query options for graph write queries. - */ - -/** - * Creates a new instance of {@link Client}. - * @classdesc - * Represents a database client that maintains multiple connections to the cluster nodes, providing methods to - * execute CQL statements. - *

- -> Terminal string styling done right - -[![Build Status](https://travis-ci.org/chalk/chalk.svg?branch=master)](https://travis-ci.org/chalk/chalk) -[![Coverage Status](https://coveralls.io/repos/chalk/chalk/badge.svg?branch=master)](https://coveralls.io/r/chalk/chalk?branch=master) -[![](http://img.shields.io/badge/unicorn-approved-ff69b4.svg)](https://www.youtube.com/watch?v=9auOCbH5Ns4) - - -[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68). Although there are other ones, they either do too much or not enough. - -**Chalk is a clean and focused alternative.** - -![](https://github.com/chalk/ansi-styles/raw/master/screenshot.png) - - -## Why - -- Highly performant -- Doesn't extend `String.prototype` -- Expressive API -- Ability to nest styles -- Clean and focused -- Auto-detects color support -- Actively maintained -- [Used by ~4500 modules](https://www.npmjs.com/browse/depended/chalk) as of July 15, 2015 - - -## Install - -``` -$ npm install --save chalk -``` - - -## Usage - -Chalk comes with an easy to use composable API where you just chain and nest the styles you want. - -```js -var chalk = require('chalk'); - -// style a string -chalk.blue('Hello world!'); - -// combine styled and normal strings -chalk.blue('Hello') + 'World' + chalk.red('!'); - -// compose multiple styles using the chainable API -chalk.blue.bgRed.bold('Hello world!'); - -// pass in multiple arguments -chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'); - -// nest styles -chalk.red('Hello', chalk.underline.bgBlue('world') + '!'); - -// nest styles of the same type even (color, underline, background) -chalk.green( - 'I am a green line ' + - chalk.blue.underline.bold('with a blue substring') + - ' that becomes green again!' -); -``` - -Easily define your own themes. - -```js -var chalk = require('chalk'); -var error = chalk.bold.red; -console.log(error('Error!')); -``` - -Take advantage of console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data). - -```js -var name = 'Sindre'; -console.log(chalk.green('Hello %s'), name); -//=> Hello Sindre -``` - - -## API - -### chalk.`
