+![bignumber.js](https://raw.githubusercontent.com/MikeMcl/bignumber.js/gh-pages/bignumberjs.png)
+
+A JavaScript library for arbitrary-precision decimal and non-decimal arithmetic.
+
+[![Build Status](https://travis-ci.org/MikeMcl/bignumber.js.svg)](https://travis-ci.org/MikeMcl/bignumber.js)
+
+<br />
+
+## Features
+
+  - Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal
+  - 8 KB minified and gzipped
+  - Simple API but full-featured
+  - Works with numbers with or without fraction digits in bases from 2 to 64 inclusive
+  - Replicates the `toExponential`, `toFixed`, `toPrecision` and `toString` methods of JavaScript's Number type
+  - Includes a `toFraction` and a correctly-rounded `squareRoot` method
+  - Supports cryptographically-secure pseudo-random number generation
+  - No dependencies
+  - Wide platform compatibility: uses JavaScript 1.5 (ECMAScript 3) features only
+  - Comprehensive [documentation](http://mikemcl.github.io/bignumber.js/) and test set
+
+![API](https://raw.githubusercontent.com/MikeMcl/bignumber.js/gh-pages/API.png)
+
+If a smaller and simpler library is required see [big.js](https://github.com/MikeMcl/big.js/).
+It's less than half the size but only works with decimal numbers and only has half the methods.
+It also does not allow `NaN` or `Infinity`, or have the configuration options of this library.
+
+See also [decimal.js](https://github.com/MikeMcl/decimal.js/), which among other things adds support for non-integer powers, and performs all operations to a specified number of significant digits.
+
+## Load
+
+The library is the single JavaScript file *bignumber.js* (or minified, *bignumber.min.js*).
+
+```html
+<script src='relative/path/to/bignumber.js'></script>
+```
+
+For [Node.js](http://nodejs.org), the library is available from the [npm](https://npmjs.org/) registry
+
+    $ npm install bignumber.js
+
+```javascript
+var BigNumber = require('bignumber.js');
+```
+
+To load with AMD loader libraries such as [requireJS](http://requirejs.org/):
+
+```javascript
+require(['path/to/bignumber'], function(BigNumber) {
+    // Use BigNumber here in local scope. No global BigNumber.
+});
+```
+
+## Use
+
+*In all examples below, `var`, semicolons and `toString` calls are not shown.
+If a commented-out value is in quotes it means `toString` has been called on the preceding expression.*
+
+The library exports a single function: `BigNumber`, the constructor of BigNumber instances.
+
+It accepts a value of type number *(up to 15 significant digits only)*, string or BigNumber object,
+
+```javascript
+x = new BigNumber(123.4567)
+y = new BigNumber('123456.7e-3')
+z = new BigNumber(x)
+x.equals(y) && y.equals(z) && x.equals(z)      // true
+```
+
+
+and a base from 2 to 64 inclusive can be specified.
+
+```javascript
+x = new BigNumber(1011, 2)          // "11"
+y = new BigNumber('zz.9', 36)       // "1295.25"
+z = x.plus(y)                       // "1306.25"
+```
+
+A BigNumber is immutable in the sense that it is not changed by its methods.
+
+```javascript
+0.3 - 0.1                           // 0.19999999999999998
+x = new BigNumber(0.3)
+x.minus(0.1)                        // "0.2"
+x                                   // "0.3"
+```
+
+The methods that return a BigNumber can be chained.
+
+```javascript
+x.dividedBy(y).plus(z).times(9).floor()
+x.times('1.23456780123456789e+9').plus(9876.5432321).dividedBy('4444562598.111772').ceil()
+```
+
+Many method names have a shorter alias.
+
+```javascript
+x.squareRoot().dividedBy(y).toPower(3).equals(x.sqrt().div(y).pow(3))         // true
+x.cmp(y.mod(z).neg()) == 1 && x.comparedTo(y.modulo(z).negated()) == 1        // true
+```
+
+Like JavaScript's number type, there are `toExponential`, `toFixed` and `toPrecision` methods
+
+```javascript
+x = new BigNumber(255.5)
+x.toExponential(5)                  // "2.55500e+2"
+x.toFixed(5)                        // "255.50000"
+x.toPrecision(5)                    // "255.50"
+x.toNumber()                        // 255.5
+```
+
+ and a base can be specified for `toString`.
+
+ ```javascript
+ x.toString(16)                     // "ff.8"
+ ```
+
+There is also a `toFormat` method which may be useful for internationalisation
+
+```javascript
+y = new BigNumber('1234567.898765')
+y.toFormat(2)                       // "1,234,567.90"
+```
+
+The maximum number of decimal places of the result of an operation involving division (i.e. a division, square root, base conversion or negative power operation) is set using the `config` method of the `BigNumber` constructor.
+
+The other arithmetic operations always give the exact result.
+
+```javascript
+BigNumber.config({ DECIMAL_PLACES: 10, ROUNDING_MODE: 4 })
+
+x = new BigNumber(2);
+y = new BigNumber(3);
+z = x.div(y)                        // "0.6666666667"
+z.sqrt()                            // "0.8164965809"
+z.pow(-3)                           // "3.3749999995"
+z.toString(2)                       // "0.1010101011"
+z.times(z)                          // "0.44444444448888888889"
+z.times(z).round(10)                // "0.4444444445"
+```
+
+There is a `toFraction` method with an optional *maximum denominator* argument
+
+```javascript
+y = new BigNumber(355)
+pi = y.dividedBy(113)               // "3.1415929204"
+pi.toFraction()                     // [ "7853982301", "2500000000" ]
+pi.toFraction(1000)                 // [ "355", "113" ]
+```
+
+and `isNaN` and `isFinite` methods, as `NaN` and `Infinity` are valid `BigNumber` values.
+
+```javascript
+x = new BigNumber(NaN)                                           // "NaN"
+y = new BigNumber(Infinity)                                      // "Infinity"
+x.isNaN() && !y.isNaN() && !x.isFinite() && !y.isFinite()        // true
+```
+
+The value of a BigNumber is stored in a decimal floating point format in terms of a coefficient, exponent and sign.
+
+
+```javascript
+x = new BigNumber(-123.456);
+x.c                                 // [ 123, 45600000000000 ]  coefficient (i.e. significand)
+x.e                                 // 2                        exponent
+x.s                                 // -1                       sign
+```
+
+
+Multiple BigNumber constructors can be created, each with their own independent configuration which applies to all BigNumber's created from it.
+
+```javascript
+// Set DECIMAL_PLACES for the original BigNumber constructor
+BigNumber.config({ DECIMAL_PLACES: 10 })
+
+// Create another BigNumber constructor, optionally passing in a configuration object
+BN = BigNumber.another({ DECIMAL_PLACES: 5 })
+
+x = new BigNumber(1)
+y = new BN(1)
+
+x.div(3)                            // '0.3333333333'
+y.div(3)                            // '0.33333'
+```
+
+For futher information see the [API](http://mikemcl.github.io/bignumber.js/) reference in the *doc* directory.
+
+## Test
+
+The *test* directory contains the test scripts for each method.
+
+The tests can be run with Node or a browser. For Node use
+
+    $ npm test
+
+or
+
+    $ node test/every-test
+
+To test a single method, e.g.
+
+    $ node test/toFraction
+
+For the browser, see *every-test.html* and *single-test.html* in the *test/browser* directory.
+
+*bignumber-vs-number.html* enables some of the methods of bignumber.js to be compared with those of JavaScript's number type.
+
+## Versions
+
+Version 1.x.x of this library is still supported on the 'original' branch. The advantages of later versions are that they are considerably faster for numbers with many digits and that there are some added methods (see Change Log below). The disadvantages are more lines of code and increased code complexity, and the loss of simplicity in no longer having the coefficient of a BigNumber stored in base 10.
+
+## Performance
+
+See the [README](https://github.com/MikeMcl/bignumber.js/tree/master/perf) in the *perf* directory.
+
+## Build
+
+For Node, if [uglify-js](https://github.com/mishoo/UglifyJS2) is installed
+
+    npm install uglify-js -g
+
+then
+
+    npm run build
+
+will create *bignumber.min.js*.
+
+A source map will also be created in the root directory.

+      From v2.0.0 of this library, the value of the coefficient of a BigNumber is stored in a
+      normalised base <code>100000000000000</code> floating point format, as opposed to the base
+      <code>10</code> format used in v1.x.x

+    <p>
+      This change means the properties of a BigNumber are now best considered to be read-only.
+      Previously it was acceptable to change the exponent of a BigNumber by writing to its exponent

+      need to be altered.

+
+    <h6>Why are trailing fractional zeros removed from BigNumbers?</h6>
+    <p>
+      Some arbitrary-precision libraries retain trailing fractional zeros as they can indicate the
+      precision of a value. This can be useful but the results of arithmetic operations can be
+      misleading.
+    </p>
+    <pre>
+x = new BigDecimal("1.0")
+y = new BigDecimal("1.1000")
+z = x.add(y)                      // 2.1000
+
+x = new BigDecimal("1.20")
+y = new BigDecimal("3.45000")
+z = x.multiply(y)                 // 4.1400000</pre>
+    <p>
+      To specify the precision of a value is to specify that the value lies
+      within a certain range.
+    </p>
+    <p>
+      In the first example, <code>x</code> has a value of <code>1.0</code>. The trailing zero shows
+      the precision of the value, implying that it is in the range <code>0.95</code> to
+      <code>1.05</code>. Similarly, the precision indicated by the trailing zeros of <code>y</code>
+      indicates that the value is in the range <code>1.09995</code> to <code>1.10005</code>.
+    </p>
+    <p>
+      If we  add the two lowest values in the ranges we have, <code>0.95 + 1.09995 = 2.04995</code>,
+      and if we add the two highest values we have, <code>1.05 + 1.10005 = 2.15005</code>, so the
+      range of the result of the addition implied by the precision of its operands is
+      <code>2.04995</code> to <code>2.15005</code>.
+    </p>
+    <p>
+      The result given by BigDecimal of <code>2.1000</code> however, indicates that the value is in
+      the range <code>2.09995</code> to <code>2.10005</code> and therefore the precision implied by
+      its trailing zeros may be misleading.
+    </p>
+    <p>
+      In the second example, the true range is <code>4.122744</code> to <code>4.157256</code> yet
+      the BigDecimal answer of <code>4.1400000</code> indicates a range of <code>4.13999995</code>
+      to  <code>4.14000005</code>. Again, the precision implied by the trailing zeros may be
+      misleading.
+    </p>
+    <p>
+      This library, like binary floating point and most calculators, does not retain trailing
+      fractional zeros. Instead, the <code>toExponential</code>, <code>toFixed</code> and
+      <code>toPrecision</code> methods enable trailing zeros to be added if and when required.<br />
+    </p>

student/node_modules/inherits/README.md

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+  the user with a good error message for it (#204).
+* Switch to `UTF8_GENERAL_CI` (previously `UTF8_UNICODE_CI`) as the default
+  charset for all connections to avoid strange MySQL performance issues (#200),
+  and also make the charset user configurable.
+* Fix BLOB type casting for `TINY_BLOB`, `MEDIUM_BLOB` and `LONG_BLOB`.
+* Add support for sending and receiving large (> 16 MB) packets.
+
+## v2.0.0-alpha (2012-05-15)
+
+This release is a rewrite. You should carefully test your application after
+upgrading to avoid problems. This release features many improvements, most
+importantly:
+
+* ~5x faster than v0.9.x for parsing query results
+* Support for pause() / resume() (for streaming rows)
+* Support for multiple statement queries
+* Support for stored procedures
+* Support for transactions
+* Support for binary columns (as blobs)
+* Consistent & well documented error handling
+* A new Connection class that has well defined semantics (unlike the old Client class).
+* Convenient escaping of objects / arrays that allows for simpler query construction
+* A significantly simpler code base
+* Many bug fixes & other small improvements (Closed 62 out of 66 GitHub issues)
+
+Below are a few notes on the upgrade process itself:
+
+The first thing you will run into is that the old `Client` class is gone and
+has been replaced with a less ambitious `Connection` class. So instead of
+`mysql.createClient()`, you now have to:
+
+```js
+var mysql      = require('mysql');
+var connection = mysql.createConnection({
+  host     : 'localhost',
+  user     : 'me',
+  password : 'secret',
+});
+
+connection.query('SELECT 1', function(err, rows) {
+  if (err) throw err;
+
+  console.log('Query result: ', rows);
+});
+
+connection.end();
+```
+
+The new `Connection` class does not try to handle re-connects, please study the
+`Server disconnects` section in the new Readme.
+
+Other than that, the interface has stayed very similar. Here are a few things
+to check out so:
+
+* BIGINT's are now cast into strings
+* Binary data is now cast to buffers
+* The `'row'` event on the `Query` object is now called `'result'` and will
+  also be emitted for queries that produce an OK/Error response.
+* Error handling is consistently defined now, check the Readme
+* Escaping has become more powerful which may break your code if you are
+  currently using objects to fill query placeholders.
+* Connections can now be established explicitly again, so you may wish to do so

+## Install
+
+```sh
+$ npm install mysql
+```
+
+For information about the previous 0.9.x releases, visit the [v0.9 branch][].
+
+Sometimes I may also ask you to install the latest version from Github to check
+if a bugfix is working. In this case, please do:
+
+```sh
+$ npm install mysqljs/mysql
+```
+
+[v0.9 branch]: https://github.com/mysqljs/mysql/tree/v0.9
+
+## Introduction
+
+This is a node.js driver for mysql. It is written in JavaScript, does not
+require compiling, and is 100% MIT licensed.
+
+Here is an example on how to use it:
+
+```js
+var mysql      = require('mysql');
+var connection = mysql.createConnection({
+  host     : 'localhost',
+  user     : 'me',
+  password : 'secret',
+  database : 'my_db'
+});
+
+connection.connect();
+
+connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
+  if (error) throw error;
+  console.log('The solution is: ', results[0].solution);
+});
+
+connection.end();
+```
+
+From this example, you can learn the following:
+
+* Every method you invoke on a connection is queued and executed in sequence.
+* Closing the connection is done using `end()` which makes sure all remaining
+  queries are executed before sending a quit packet to the mysql server.

+
+## Establishing connections
+
+The recommended way to establish a connection is this:
+
+```js
+var mysql      = require('mysql');
+var connection = mysql.createConnection({
+  host     : 'example.org',
+  user     : 'bob',
+  password : 'secret'
+});
+
+connection.connect(function(err) {
+  if (err) {
+    console.error('error connecting: ' + err.stack);
+    return;
+  }
+
+  console.log('connected as id ' + connection.threadId);
+});
+```
+
+However, a connection can also be implicitly established by invoking a query:
+
+```js
+var mysql      = require('mysql');
+var connection = mysql.createConnection(...);
+
+connection.query('SELECT 1', function (error, results, fields) {
+  if (error) throw error;
+  // connected!
+});
+```
+
+Depending on how you like to handle your errors, either method may be
+appropriate. Any type of connection error (handshake or network) is considered
+a fatal error, see the [Error Handling](#error-handling) section for more
+information.
+
+## Connection options
+
+When establishing a connection, you can set the following options:
+
+* `host`: The hostname of the database you are connecting to. (Default:
+  `localhost`)
+* `port`: The port number to connect to. (Default: `3306`)
+* `localAddress`: The source IP address to use for TCP connection. (Optional)
+* `socketPath`: The path to a unix domain socket to connect to. When used `host`
+  and `port` are ignored.
+* `user`: The MySQL user to authenticate as.
+* `password`: The password of that MySQL user.
+* `database`: Name of the database to use for this connection (Optional).
+* `charset`: The charset for the connection. This is called "collation" in the SQL-level
+  of MySQL (like `utf8_general_ci`). If a SQL-level charset is specified (like `utf8mb4`)
+  then the default collation for that charset is used. (Default: `'UTF8_GENERAL_CI'`)
+* `timezone`: The timezone configured on the MySQL server. This is used to type cast server date/time values to JavaScript `Date` object and vice versa. This can be `'local'`, `'Z'`, or an offset in the form `+HH:MM` or `-HH:MM`. (Default: `'local'`)
+* `connectTimeout`: The milliseconds before a timeout occurs during the initial connection
+  to the MySQL server. (Default: `10000`)
+* `stringifyObjects`: Stringify objects instead of converting to values. See
+issue [#501](https://github.com/mysqljs/mysql/issues/501). (Default: `false`)
+* `insecureAuth`: Allow connecting to MySQL instances that ask for the old
+  (insecure) authentication method. (Default: `false`)
+* `typeCast`: Determines if column values should be converted to native
+   JavaScript types. (Default: `true`)
+* `queryFormat`: A custom query format function. See [Custom format](#custom-format).
+* `supportBigNumbers`: When dealing with big numbers (BIGINT and DECIMAL columns) in the database,
+  you should enable this option (Default: `false`).
+* `bigNumberStrings`: Enabling both `supportBigNumbers` and `bigNumberStrings` forces big numbers
+  (BIGINT and DECIMAL columns) to be always returned as JavaScript String objects (Default: `false`).
+  Enabling `supportBigNumbers` but leaving `bigNumberStrings` disabled will return big numbers as String
+  objects only when they cannot be accurately represented with [JavaScript Number objects] (http://ecma262-5.com/ELS5_HTML.htm#Section_8.5)
+  (which happens when they exceed the [-2^53, +2^53] range), otherwise they will be returned as
+  Number objects. This option is ignored if `supportBigNumbers` is disabled.
+* `dateStrings`: Force date types (TIMESTAMP, DATETIME, DATE) to be returned as strings rather then
+   inflated into JavaScript Date objects. Can be `true`/`false` or an array of type names to keep as
+   strings. (Default: `false`)
+* `debug`: Prints protocol details to stdout. Can be `true`/`false` or an array of packet type names
+   that should be printed. (Default: `false`)
+* `trace`: Generates stack traces on `Error` to include call site of library
+   entrance ("long stack traces"). Slight performance penalty for most calls.
+   (Default: `true`)
+* `multipleStatements`: Allow multiple mysql statements per query. Be careful
+  with this, it could increase the scope of SQL injection attacks. (Default: `false`)
+* `flags`: List of connection flags to use other than the default ones. It is
+  also possible to blacklist default ones. For more information, check
+  [Connection Flags](#connection-flags).
+* `ssl`: object with ssl parameters or a string containing name of ssl profile. See [SSL options](#ssl-options).
+
+
+In addition to passing these options as an object, you can also use a url
+string. For example:
+
+```js
+var connection = mysql.createConnection('mysql://user:pass@host/db?debug=true&charset=BIG5_CHINESE_CI&timezone=-0700');
+```
+
+Note: The query values are first attempted to be parsed as JSON, and if that
+fails assumed to be plaintext strings.
+
+### SSL options
+
+The `ssl` option in the connection options takes a string or an object. When given a string,
+it uses one of the predefined SSL profiles included. The following profiles are included:
+
+* `"Amazon RDS"`: this profile is for connecting to an Amazon RDS server and contains the
+  certificates from https://rds.amazonaws.com/doc/rds-ssl-ca-cert.pem and
+  https://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem
+
+When connecting to other servers, you will need to provide an object of options, in the
+same format as [crypto.createCredentials](http://nodejs.org/api/crypto.html#crypto_crypto_createcredentials_details).
+Please note the arguments expect a string of the certificate, not a file name to the
+certificate. Here is a simple example:
+
+```js
+var connection = mysql.createConnection({
+  host : 'localhost',
+  ssl  : {
+    ca : fs.readFileSync(__dirname + '/mysql-ca.crt')
+  }
+});
+```
+
+You can also connect to a MySQL server without properly providing the appropriate
+CA to trust. _You should not do this_.
+
+```js
+var connection = mysql.createConnection({
+  host : 'localhost',
+  ssl  : {
+    // DO NOT DO THIS
+    // set up your ca correctly to trust the connection
+    rejectUnauthorized: false
+  }
+});
+```
+
+## Terminating connections
+
+There are two ways to end a connection. Terminating a connection gracefully is
+done by calling the `end()` method:
+
+```js
+connection.end(function(err) {
+  // The connection is terminated now
+});
+```
+
+This will make sure all previously enqueued queries are still before sending a
+`COM_QUIT` packet to the MySQL server. If a fatal error occurs before the
+`COM_QUIT` packet can be sent, an `err` argument will be provided to the
+callback, but the connection will be terminated regardless of that.
+
+An alternative way to end the connection is to call the `destroy()` method.
+This will cause an immediate termination of the underlying socket.
+Additionally `destroy()` guarantees that no more events or callbacks will be
+triggered for the connection.
+
+```js
+connection.destroy();
+```
+
+Unlike `end()` the `destroy()` method does not take a callback argument.
+
+## Pooling connections
+
+Rather than creating and managing connections one-by-one, this module also
+provides built-in connection pooling using `mysql.createPool(config)`.
+[Read more about connection pooling](https://en.wikipedia.org/wiki/Connection_pool).
+
+Use pool directly.
+```js
+var mysql = require('mysql');
+var pool  = mysql.createPool({
+  connectionLimit : 10,
+  host            : 'example.org',
+  user            : 'bob',
+  password        : 'secret',
+  database        : 'my_db'
+});
+
+pool.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
+  if (error) throw error;
+  console.log('The solution is: ', results[0].solution);
+});
+```
+
+Connections can be pooled to ease sharing a single connection, or managing
+multiple connections.
+
+```js
+var mysql = require('mysql');
+var pool  = mysql.createPool({
+  host     : 'example.org',
+  user     : 'bob',
+  password : 'secret',
+  database : 'my_db'
+});
+
+pool.getConnection(function(err, connection) {
+  // connected! (unless `err` is set)
+});
+```
+
+When you are done with a connection, just call `connection.release()` and the
+connection will return to the pool, ready to be used again by someone else.
+
+```js
+var mysql = require('mysql');
+var pool  = mysql.createPool(...);
+
+pool.getConnection(function(err, connection) {
+  // Use the connection
+  connection.query('SELECT something FROM sometable', function (error, results, fields) {
+    // And done with the connection.
+    connection.release();
+
+    // Handle error after the release.
+    if (error) throw error;
+
+    // Don't use the connection here, it has been returned to the pool.
+  });
+});
+```
+
+If you would like to close the connection and remove it from the pool, use
+`connection.destroy()` instead. The pool will create a new connection the next
+time one is needed.
+
+Connections are lazily created by the pool. If you configure the pool to allow
+up to 100 connections, but only ever use 5 simultaneously, only 5 connections
+will be made. Connections are also cycled round-robin style, with connections
+being taken from the top of the pool and returning to the bottom.
+
+When a previous connection is retrieved from the pool, a ping packet is sent
+to the server to check if the connection is still good.
+
+## Pool options
+
+Pools accept all the same [options as a connection](#connection-options).
+When creating a new connection, the options are simply passed to the connection
+constructor. In addition to those options pools accept a few extras:
+
+* `acquireTimeout`: The milliseconds before a timeout occurs during the connection
+  acquisition. This is slightly different from `connectTimeout`, because acquiring
+  a pool connection does not always involve making a connection. (Default: `10000`)
+* `waitForConnections`: Determines the pool's action when no connections are
+  available and the limit has been reached. If `true`, the pool will queue the
+  connection request and call it when one becomes available. If `false`, the
+  pool will immediately call back with an error. (Default: `true`)
+* `connectionLimit`: The maximum number of connections to create at once.
+  (Default: `10`)
+* `queueLimit`: The maximum number of connection requests the pool will queue
+  before returning an error from `getConnection`. If set to `0`, there is no
+  limit to the number of queued connection requests. (Default: `0`)
+
+## Pool events
+
+### acquire
+
+The pool will emit an `acquire` event when a connection is acquired from the pool.
+This is called after all acquiring activity has been performed on the connection,
+right before the connection is handed to the callback of the acquiring code.
+
+```js
+pool.on('acquire', function (connection) {
+  console.log('Connection %d acquired', connection.threadId);
+});
+```
+
+### connection
+
+The pool will emit a `connection` event when a new connection is made within the pool.
+If you need to set session variables on the connection before it gets used, you can
+listen to the `connection` event.
+
+```js
+pool.on('connection', function (connection) {
+  connection.query('SET SESSION auto_increment_increment=1')
+});
+```
+
+### enqueue
+
+The pool will emit an `enqueue` event when a callback has been queued to wait for
+an available connection.
+
+```js
+pool.on('enqueue', function () {
+  console.log('Waiting for available connection slot');
+});
+```
+
+### release
+
+The pool will emit a `release` event when a connection is released back to the
+pool. This is called after all release activity has been performed on the connection,
+so the connection will be listed as free at the time of the event.
+
+```js
+pool.on('release', function (connection) {
+  console.log('Connection %d released', connection.threadId);
+});
+```
+
+## Closing all the connections in a pool
+
+When you are done using the pool, you have to end all the connections or the
+Node.js event loop will stay active until the connections are closed by the
+MySQL server. This is typically done if the pool is used in a script or when
+trying to gracefully shutdown a server. To end all the connections in the
+pool, use the `end` method on the pool:
+
+```js
+pool.end(function (err) {
+  // all connections in the pool have ended
+});
+```
+
+The `end` method takes an _optional_ callback that you can use to know once
+all the connections have ended.
+
+**Once `pool.end()` has been called, `pool.getConnection` and other operations
+can no longer be performed**
+
+This works by calling `connection.end()` on every active connection in the
+pool, which queues a `QUIT` packet on the connection. And sets a flag to
+prevent `pool.getConnection` from continuing to create any new connections.
+
+Since this queues a `QUIT` packet on each connection, all commands / queries
+already in progress will complete, just like calling `connection.end()`. If
+`pool.end` is called and there are connections that have not yet been released,
+those connections will fail to execute any new commands after the `pool.end`
+since they have a pending `QUIT` packet in their queue; wait until releasing
+all connections back to the pool before calling `pool.end()`.
+
+Since the `pool.query` method is a short-hand for the `pool.getConnection` ->
+`connection.query` -> `connection.release()` flow, calling `pool.end()` before
+all the queries added via `pool.query` have completed, since the underlying
+`pool.getConnection` will fail due to all connections ending and not allowing
+new connections to be created.
+
+## PoolCluster
+
+PoolCluster provides multiple hosts connection. (group & retry & selector)
+
+```js
+// create
+var poolCluster = mysql.createPoolCluster();
+
+// add configurations (the config is a pool config object)
+poolCluster.add(config); // add configuration with automatic name
+poolCluster.add('MASTER', masterConfig); // add a named configuration
+poolCluster.add('SLAVE1', slave1Config);
+poolCluster.add('SLAVE2', slave2Config);
+
+// remove configurations
+poolCluster.remove('SLAVE2'); // By nodeId
+poolCluster.remove('SLAVE*'); // By target group : SLAVE1-2
+
+// Target Group : ALL(anonymous, MASTER, SLAVE1-2), Selector : round-robin(default)
+poolCluster.getConnection(function (err, connection) {});
+
+// Target Group : MASTER, Selector : round-robin
+poolCluster.getConnection('MASTER', function (err, connection) {});
+
+// Target Group : SLAVE1-2, Selector : order
+// If can't connect to SLAVE1, return SLAVE2. (remove SLAVE1 in the cluster)
+poolCluster.on('remove', function (nodeId) {
+  console.log('REMOVED NODE : ' + nodeId); // nodeId = SLAVE1
+});
+
+// A pattern can be passed with *  as wildcard
+poolCluster.getConnection('SLAVE*', 'ORDER', function (err, connection) {});
+
+// The pattern can also be a regular expression
+poolCluster.getConnection(/^SLAVE[12]$/, function (err, connection) {});
+
+// of namespace : of(pattern, selector)
+poolCluster.of('*').getConnection(function (err, connection) {});
+
+var pool = poolCluster.of('SLAVE*', 'RANDOM');
+pool.getConnection(function (err, connection) {});
+pool.getConnection(function (err, connection) {});
+pool.query(function (error, results, fields) {});
+
+// close all connections
+poolCluster.end(function (err) {
+  // all connections in the pool cluster have ended
+});
+```
+
+### PoolCluster options
+
+* `canRetry`: If `true`, `PoolCluster` will attempt to reconnect when connection fails. (Default: `true`)
+* `removeNodeErrorCount`: If connection fails, node's `errorCount` increases.
+  When `errorCount` is greater than `removeNodeErrorCount`, remove a node in the `PoolCluster`. (Default: `5`)
+* `restoreNodeTimeout`: If connection fails, specifies the number of milliseconds
+  before another connection attempt will be made. If set to `0`, then node will be
+  removed instead and never re-used. (Default: `0`)
+* `defaultSelector`: The default selector. (Default: `RR`)
+  * `RR`: Select one alternately. (Round-Robin)
+  * `RANDOM`: Select the node by random function.
+  * `ORDER`: Select the first node available unconditionally.
+
+```js
+var clusterConfig = {
+  removeNodeErrorCount: 1, // Remove the node immediately when connection fails.
+  defaultSelector: 'ORDER'
+};
+
+var poolCluster = mysql.createPoolCluster(clusterConfig);
+```
+
+## Switching users and altering connection state
+
+MySQL offers a changeUser command that allows you to alter the current user and
+other aspects of the connection without shutting down the underlying socket:
+
+```js
+connection.changeUser({user : 'john'}, function(err) {
+  if (err) throw err;
+});
+```
+
+The available options for this feature are:
+
+* `user`: The name of the new user (defaults to the previous one).
+* `password`: The password of the new user (defaults to the previous one).
+* `charset`: The new charset (defaults to the previous one).
+* `database`: The new database (defaults to the previous one).
+
+A sometimes useful side effect of this functionality is that this function also
+resets any connection state (variables, transactions, etc.).
+
+Errors encountered during this operation are treated as fatal connection errors
+by this module.
+
+## Server disconnects
+
+You may lose the connection to a MySQL server due to network problems, the
+server timing you out, the server being restarted, or crashing. All of these
+events are considered fatal errors, and will have the `err.code =
+'PROTOCOL_CONNECTION_LOST'`.  See the [Error Handling](#error-handling) section
+for more information.
+
+Re-connecting a connection is done by establishing a new connection. Once
+terminated, an existing connection object cannot be re-connected by design.
+
+With Pool, disconnected connections will be removed from the pool freeing up
+space for a new connection to be created on the next getConnection call.
+
+## Performing queries
+
+The most basic way to perform a query is to call the `.query()` method on an object
+(like a `Connection`, `Pool`, or `PoolNamespace` instance).
+
+The simplest form of .`query()` is `.query(sqlString, callback)`, where a SQL string
+is the first argument and the second is a callback:
+
+```js
+connection.query('SELECT * FROM `books` WHERE `author` = "David"', function (error, results, fields) {
+  // error will be an Error if one occurred during the query
+  // results will contain the results of the query
+  // fields will contain information about the returned results fields (if any)
+});
+```
+
+The second form `.query(sqlString, values, callback)` comes when using
+placeholder values (see [escaping query values](#escaping-query-values)):
+
+```js
+connection.query('SELECT * FROM `books` WHERE `author` = ?', ['David'], function (error, results, fields) {
+  // error will be an Error if one occurred during the query
+  // results will contain the results of the query
+  // fields will contain information about the returned results fields (if any)
+});
+```
+
+The third form `.query(options, callback)` comes when using various advanced
+options on the query, like [escaping query values](#escaping-query-values),
+[joins with overlapping column names](#joins-with-overlapping-column-names),
+[timeouts](#timeout), and [type casting](#type-casting).
+
+```js
+connection.query({
+  sql: 'SELECT * FROM `books` WHERE `author` = ?',
+  timeout: 40000, // 40s
+  values: ['David']
+}, function (error, results, fields) {
+  // error will be an Error if one occurred during the query
+  // results will contain the results of the query
+  // fields will contain information about the returned results fields (if any)
+});
+```
+
+Note that a combination of the second and third forms can be used where the
+placeholder values are passed as an argument and not in the options object.
+The `values` argument will override the `values` in the option object.
+
+```js
+connection.query({
+    sql: 'SELECT * FROM `books` WHERE `author` = ?',
+    timeout: 40000, // 40s
+  },
+  ['David'],
+  function (error, results, fields) {
+    // error will be an Error if one occurred during the query
+    // results will contain the results of the query
+    // fields will contain information about the returned results fields (if any)
+  }
+);
+```
+
+## Escaping query values
+
+**Caution** These methods of escaping values only works when the
+[NO_BACKSLASH_ESCAPES](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html#sqlmode_no_backslash_escapes)
+SQL mode is disabled (which is the default state for MySQL servers).
+
+In order to avoid SQL Injection attacks, you should always escape any user
+provided data before using it inside a SQL query. You can do so using the
+`mysql.escape()`, `connection.escape()` or `pool.escape()` methods:
+
+```js
+var userId = 'some user provided value';
+var sql    = 'SELECT * FROM users WHERE id = ' + connection.escape(userId);
+connection.query(sql, function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+```
+
+Alternatively, you can use `?` characters as placeholders for values you would
+like to have escaped like this:
+
+```js
+connection.query('SELECT * FROM users WHERE id = ?', [userId], function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+```
+
+Multiple placeholders are mapped to values in the same order as passed. For example,
+in the following query `foo` equals `a`, `bar` equals `b`, `baz` equals `c`, and
+`id` will be `userId`:
+
+```js
+connection.query('UPDATE users SET foo = ?, bar = ?, baz = ? WHERE id = ?', ['a', 'b', 'c', userId], function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+```
+
+This looks similar to prepared statements in MySQL, however it really just uses
+the same `connection.escape()` method internally.
+
+**Caution** This also differs from prepared statements in that all `?` are
+replaced, even those contained in comments and strings.
+
+Different value types are escaped differently, here is how:
+
+* Numbers are left untouched
+* Booleans are converted to `true` / `false`
+* Date objects are converted to `'YYYY-mm-dd HH:ii:ss'` strings
+* Buffers are converted to hex strings, e.g. `X'0fa5'`
+* Strings are safely escaped
+* Arrays are turned into list, e.g. `['a', 'b']` turns into `'a', 'b'`
+* Nested arrays are turned into grouped lists (for bulk inserts), e.g. `[['a',
+  'b'], ['c', 'd']]` turns into `('a', 'b'), ('c', 'd')`
+* Objects that have a `toSqlString` method will have `.toSqlString()` called
+  and the returned value is used as the raw SQL.
+* Objects are turned into `key = 'val'` pairs for each enumerable property on
+  the object. If the property's value is a function, it is skipped; if the
+  property's value is an object, toString() is called on it and the returned
+  value is used.
+* `undefined` / `null` are converted to `NULL`
+* `NaN` / `Infinity` are left as-is. MySQL does not support these, and trying
+  to insert them as values will trigger MySQL errors until they implement
+  support.
+
+This escaping allows you to do neat things like this:
+
+```js
+var post  = {id: 1, title: 'Hello MySQL'};
+var query = connection.query('INSERT INTO posts SET ?', post, function (error, results, fields) {
+  if (error) throw error;
+  // Neat!
+});
+console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'
+```
+
+And the `toSqlString` method allows you to form complex queries with functions:
+
+```js
+var CURRENT_TIMESTAMP = { toSqlString: function() { return 'CURRENT_TIMESTAMP()'; } };
+var sql = mysql.format('UPDATE posts SET modified = ? WHERE id = ?', [CURRENT_TIMESTAMP, 42]);
+console.log(sql); // UPDATE posts SET modified = CURRENT_TIMESTAMP() WHERE id = 42
+```
+
+To generate objects with a `toSqlString` method, the `mysql.raw()` method can
+be used. This creates an object that will be left un-touched when using in a `?`
+placeholder, useful for using functions as dynamic values:
+
+**Caution** The string provided to `mysql.raw()` will skip all escaping
+functions when used, so be careful when passing in unvalidated input.
+
+```js
+var CURRENT_TIMESTAMP = mysql.raw('CURRENT_TIMESTAMP()');
+var sql = mysql.format('UPDATE posts SET modified = ? WHERE id = ?', [CURRENT_TIMESTAMP, 42]);
+console.log(sql); // UPDATE posts SET modified = CURRENT_TIMESTAMP() WHERE id = 42
+```
+
+If you feel the need to escape queries by yourself, you can also use the escaping
+function directly:
+
+```js
+var query = "SELECT * FROM posts WHERE title=" + mysql.escape("Hello MySQL");
+
+console.log(query); // SELECT * FROM posts WHERE title='Hello MySQL'
+```
+
+## Escaping query identifiers
+
+If you can't trust an SQL identifier (database / table / column name) because it is
+provided by a user, you should escape it with `mysql.escapeId(identifier)`,
+`connection.escapeId(identifier)` or `pool.escapeId(identifier)` like this:
+
+```js
+var sorter = 'date';
+var sql    = 'SELECT * FROM posts ORDER BY ' + connection.escapeId(sorter);
+connection.query(sql, function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+```
+
+It also supports adding qualified identifiers. It will escape both parts.
+
+```js
+var sorter = 'date';
+var sql    = 'SELECT * FROM posts ORDER BY ' + connection.escapeId('posts.' + sorter);
+// -> SELECT * FROM posts ORDER BY `posts`.`date`
+```
+
+If you do not want to treat `.` as qualified identifiers, you can set the second
+argument to `true` in order to keep the string as a literal identifier:
+
+```js
+var sorter = 'date.2';
+var sql    = 'SELECT * FROM posts ORDER BY ' + connection.escapeId(sorter, true);
+// -> SELECT * FROM posts ORDER BY `date.2`
+```
+
+Alternatively, you can use `??` characters as placeholders for identifiers you would
+like to have escaped like this:
+
+```js
+var userId = 1;
+var columns = ['username', 'email'];
+var query = connection.query('SELECT ?? FROM ?? WHERE id = ?', [columns, 'users', userId], function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+
+console.log(query.sql); // SELECT `username`, `email` FROM `users` WHERE id = 1
+```
+**Please note that this last character sequence is experimental and syntax might change**
+
+When you pass an Object to `.escape()` or `.query()`, `.escapeId()` is used to avoid SQL injection in object keys.
+
+### Preparing Queries
+
+You can use mysql.format to prepare a query with multiple insertion points, utilizing the proper escaping for ids and values. A simple example of this follows:
+
+```js
+var sql = "SELECT * FROM ?? WHERE ?? = ?";
+var inserts = ['users', 'id', userId];
+sql = mysql.format(sql, inserts);
+```
+
+Following this you then have a valid, escaped query that you can then send to the database safely. This is useful if you are looking to prepare the query before actually sending it to the database. As mysql.format is exposed from SqlString.format you also have the option (but are not required) to pass in stringifyObject and timezone, allowing you provide a custom means of turning objects into strings, as well as a location-specific/timezone-aware Date.
+
+### Custom format
+
+If you prefer to have another type of query escape format, there's a connection configuration option you can use to define a custom format function. You can access the connection object if you want to use the built-in `.escape()` or any other connection function.
+
+Here's an example of how to implement another format:
+
+```js
+connection.config.queryFormat = function (query, values) {
+  if (!values) return query;
+  return query.replace(/\:(\w+)/g, function (txt, key) {
+    if (values.hasOwnProperty(key)) {
+      return this.escape(values[key]);
+    }
+    return txt;
+  }.bind(this));
+};
+
+connection.query("UPDATE posts SET title = :title", { title: "Hello MySQL" });
+```
+
+## Getting the id of an inserted row
+
+If you are inserting a row into a table with an auto increment primary key, you
+can retrieve the insert id like this:
+
+```js
+connection.query('INSERT INTO posts SET ?', {title: 'test'}, function (error, results, fields) {
+  if (error) throw error;
+  console.log(results.insertId);
+});
+```
+
+When dealing with big numbers (above JavaScript Number precision limit), you should
+consider enabling `supportBigNumbers` option to be able to read the insert id as a
+string, otherwise it will throw an error.
+
+This option is also required when fetching big numbers from the database, otherwise
+you will get values rounded to hundreds or thousands due to the precision limit.
+
+## Getting the number of affected rows
+
+You can get the number of affected rows from an insert, update or delete statement.
+
+```js
+connection.query('DELETE FROM posts WHERE title = "wrong"', function (error, results, fields) {
+  if (error) throw error;
+  console.log('deleted ' + results.affectedRows + ' rows');
+})
+```
+
+## Getting the number of changed rows
+
+You can get the number of changed rows from an update statement.
+
+"changedRows" differs from "affectedRows" in that it does not count updated rows
+whose values were not changed.
+
+```js
+connection.query('UPDATE posts SET ...', function (error, results, fields) {
+  if (error) throw error;
+  console.log('changed ' + results.changedRows + ' rows');
+})
+```
+
+## Getting the connection ID
+
+You can get the MySQL connection ID ("thread ID") of a given connection using the `threadId`
+property.
+
+```js
+connection.connect(function(err) {
+  if (err) throw err;
+  console.log('connected as id ' + connection.threadId);
+});
+```
+
+## Executing queries in parallel
+
+The MySQL protocol is sequential, this means that you need multiple connections
+to execute queries in parallel. You can use a Pool to manage connections, one
+simple approach is to create one connection per incoming http request.
+
+## Streaming query rows
+
+Sometimes you may want to select large quantities of rows and process each of
+them as they are received. This can be done like this:
+
+```js
+var query = connection.query('SELECT * FROM posts');
+query
+  .on('error', function(err) {
+    // Handle error, an 'end' event will be emitted after this as well
+  })
+  .on('fields', function(fields) {
+    // the field packets for the rows to follow
+  })
+  .on('result', function(row) {
+    // Pausing the connnection is useful if your processing involves I/O
+    connection.pause();
+
+    processRow(row, function() {
+      connection.resume();
+    });
+  })
+  .on('end', function() {
+    // all rows have been received
+  });
+```
+
+Please note a few things about the example above:
+
+* Usually you will want to receive a certain amount of rows before starting to
+  throttle the connection using `pause()`. This number will depend on the
+  amount and size of your rows.
+* `pause()` / `resume()` operate on the underlying socket and parser. You are
+  guaranteed that no more `'result'` events will fire after calling `pause()`.
+* You MUST NOT provide a callback to the `query()` method when streaming rows.
+* The `'result'` event will fire for both rows as well as OK packets
+  confirming the success of a INSERT/UPDATE query.
+* It is very important not to leave the result paused too long, or you may
+  encounter `Error: Connection lost: The server closed the connection.`
+  The time limit for this is determined by the
+  [net_write_timeout setting](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_net_write_timeout)
+  on your MySQL server.
+
+Additionally you may be interested to know that it is currently not possible to
+stream individual row columns, they will always be buffered up entirely. If you
+have a good use case for streaming large fields to and from MySQL, I'd love to
+get your thoughts and contributions on this.
+
+### Piping results with Streams
+
+The query object provides a convenience method `.stream([options])` that wraps
+query events into a [Readable Stream](http://nodejs.org/api/stream.html#stream_class_stream_readable)
+object. This stream can easily be piped downstream and provides automatic
+pause/resume, based on downstream congestion and the optional `highWaterMark`.
+The `objectMode` parameter of the stream is set to `true` and cannot be changed
+(if you need a byte stream, you will need to use a transform stream, like
+[objstream](https://www.npmjs.com/package/objstream) for example).
+
+For example, piping query results into another stream (with a max buffer of 5
+objects) is simply:
+
+```js
+connection.query('SELECT * FROM posts')
+  .stream({highWaterMark: 5})
+  .pipe(...);
+```
+
+## Multiple statement queries
+
+Support for multiple statements is disabled for security reasons (it allows for
+SQL injection attacks if values are not properly escaped). To use this feature
+you have to enable it for your connection:
+
+```js
+var connection = mysql.createConnection({multipleStatements: true});
+```
+
+Once enabled, you can execute multiple statement queries like any other query:
+
+```js
+connection.query('SELECT 1; SELECT 2', function (error, results, fields) {
+  if (error) throw error;
+  // `results` is an array with one element for every statement in the query:
+  console.log(results[0]); // [{1: 1}]
+  console.log(results[1]); // [{2: 2}]
+});
+```
+
+Additionally you can also stream the results of multiple statement queries:
+
+```js
+var query = connection.query('SELECT 1; SELECT 2');
+
+query
+  .on('fields', function(fields, index) {
+    // the fields for the result rows that follow
+  })
+  .on('result', function(row, index) {
+    // index refers to the statement this result belongs to (starts at 0)
+  });
+```
+
+If one of the statements in your query causes an error, the resulting Error
+object contains a `err.index` property which tells you which statement caused
+it. MySQL will also stop executing any remaining statements when an error
+occurs.
+
+Please note that the interface for streaming multiple statement queries is
+experimental and I am looking forward to feedback on it.
+
+## Stored procedures
+
+You can call stored procedures from your queries as with any other mysql driver.
+If the stored procedure produces several result sets, they are exposed to you
+the same way as the results for multiple statement queries.
+
+## Joins with overlapping column names
+
+When executing joins, you are likely to get result sets with overlapping column
+names.
+
+By default, node-mysql will overwrite colliding column names in the
+order the columns are received from MySQL, causing some of the received values
+to be unavailable.
+
+However, you can also specify that you want your columns to be nested below
+the table name like this:
+
+```js
+var options = {sql: '...', nestTables: true};
+connection.query(options, function (error, results, fields) {
+  if (error) throw error;
+  /* results will be an array like this now:
+  [{
+    table1: {
+      fieldA: '...',
+      fieldB: '...',
+    },
+    table2: {
+      fieldA: '...',
+      fieldB: '...',
+    },
+  }, ...]
+  */
+});
+```
+
+Or use a string separator to have your results merged.
+
+```js
+var options = {sql: '...', nestTables: '_'};
+connection.query(options, function (error, results, fields) {
+  if (error) throw error;
+  /* results will be an array like this now:
+  [{
+    table1_fieldA: '...',
+    table1_fieldB: '...',
+    table2_fieldA: '...',
+    table2_fieldB: '...',
+  }, ...]
+  */
+});
+```
+
+## Transactions
+
+Simple transaction support is available at the connection level:
+
+```js
+connection.beginTransaction(function(err) {
+  if (err) { throw err; }
+  connection.query('INSERT INTO posts SET title=?', title, function (error, results, fields) {
+    if (error) {
+      return connection.rollback(function() {
+        throw error;
+      });
+    }
+
+    var log = 'Post ' + results.insertId + ' added';
+
+    connection.query('INSERT INTO log SET data=?', log, function (error, results, fields) {
+      if (error) {
+        return connection.rollback(function() {
+          throw error;
+        });
+      }
+      connection.commit(function(err) {
+        if (err) {
+          return connection.rollback(function() {
+            throw err;
+          });
+        }
+        console.log('success!');
+      });
+    });
+  });
+});
+```
+Please note that beginTransaction(), commit() and rollback() are simply convenience
+functions that execute the START TRANSACTION, COMMIT, and ROLLBACK commands respectively.
+It is important to understand that many commands in MySQL can cause an implicit commit,
+as described [in the MySQL documentation](http://dev.mysql.com/doc/refman/5.5/en/implicit-commit.html)
+
+## Ping
+
+A ping packet can be sent over a connection using the `connection.ping` method. This
+method will send a ping packet to the server and when the server responds, the callback
+will fire. If an error occurred, the callback will fire with an error argument.
+
+```js
+connection.ping(function (err) {
+  if (err) throw err;
+  console.log('Server responded to ping');
+})
+```
+
+## Timeouts
+
+Every operation takes an optional inactivity timeout option. This allows you to
+specify appropriate timeouts for operations. It is important to note that these
+timeouts are not part of the MySQL protocol, and rather timeout operations through
+the client. This means that when a timeout is reached, the connection it occurred
+on will be destroyed and no further operations can be performed.
+
+```js
+// Kill query after 60s
+connection.query({sql: 'SELECT COUNT(*) AS count FROM big_table', timeout: 60000}, function (error, results, fields) {
+  if (error && error.code === 'PROTOCOL_SEQUENCE_TIMEOUT') {
+    throw new Error('too long to count table rows!');
+  }
+
+  if (error) {
+    throw error;
+  }
+
+  console.log(results[0].count + ' rows');
+});
+```
+
+## Error handling
+
+This module comes with a consistent approach to error handling that you should
+review carefully in order to write solid applications.
+
+Most errors created by this module are instances of the JavaScript [Error][]
+object. Additionally they typically come with two extra properties:
+
+* `err.code`: Either a [MySQL server error][] (e.g.
+  `'ER_ACCESS_DENIED_ERROR'`), a Node.js error (e.g. `'ECONNREFUSED'`) or an
+  internal error (e.g. `'PROTOCOL_CONNECTION_LOST'`).
+* `err.fatal`: Boolean, indicating if this error is terminal to the connection
+  object. If the error is not from a MySQL protocol operation, this properly
+  will not be defined.
+* `err.sql`: String, contains the full SQL of the failed query. This can be
+  useful when using a higher level interface like an ORM that is generating
+  the queries.
+* `err.sqlMessage`: String, contains the message string that provides a
+  textual description of the error. Only populated from [MySQL server error][].
+
+[Error]: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Error
+[MySQL server error]: http://dev.mysql.com/doc/refman/5.5/en/error-messages-server.html
+
+Fatal errors are propagated to *all* pending callbacks. In the example below, a
+fatal error is triggered by trying to connect to an invalid port. Therefore the
+error object is propagated to both pending callbacks:
+
+```js
+var connection = require('mysql').createConnection({
+  port: 84943, // WRONG PORT
+});
+
+connection.connect(function(err) {
+  console.log(err.code); // 'ECONNREFUSED'
+  console.log(err.fatal); // true
+});
+
+connection.query('SELECT 1', function (error, results, fields) {
+  console.log(error.code); // 'ECONNREFUSED'
+  console.log(error.fatal); // true
+});
+```
+
+Normal errors however are only delegated to the callback they belong to.  So in
+the example below, only the first callback receives an error, the second query
+works as expected:
+
+```js
+connection.query('USE name_of_db_that_does_not_exist', function (error, results, fields) {
+  console.log(error.code); // 'ER_BAD_DB_ERROR'
+});
+
+connection.query('SELECT 1', function (error, results, fields) {
+  console.log(error); // null
+  console.log(results.length); // 1
+});
+```
+
+Last but not least: If a fatal errors occurs and there are no pending
+callbacks, or a normal error occurs which has no callback belonging to it, the
+error is emitted as an `'error'` event on the connection object. This is
+demonstrated in the example below:
+
+```js
+connection.on('error', function(err) {
+  console.log(err.code); // 'ER_BAD_DB_ERROR'
+});
+
+connection.query('USE name_of_db_that_does_not_exist');
+```
+
+Note: `'error'` events are special in node. If they occur without an attached
+listener, a stack trace is printed and your process is killed.
+
+**tl;dr:** This module does not want you to deal with silent failures. You
+should always provide callbacks to your method calls. If you want to ignore
+this advice and suppress unhandled errors, you can do this:
+
+```js
+// I am Chuck Norris:
+connection.on('error', function() {});
+```
+
+## Exception Safety
+
+This module is exception safe. That means you can continue to use it, even if
+one of your callback functions throws an error which you're catching using
+'uncaughtException' or a domain.
+
+## Type casting
+
+For your convenience, this driver will cast mysql types into native JavaScript
+types by default. The following mappings exist:
+
+### Number
+
+* TINYINT
+* SMALLINT
+* INT
+* MEDIUMINT
+* YEAR
+* FLOAT
+* DOUBLE
+
+### Date
+
+* TIMESTAMP
+* DATE
+* DATETIME
+
+### Buffer
+
+* TINYBLOB
+* MEDIUMBLOB
+* LONGBLOB
+* BLOB
+* BINARY
+* VARBINARY
+* BIT (last byte will be filled with 0 bits as necessary)
+
+### String
+
+**Note** text in the binary character set is returned as `Buffer`, rather
+than a string.
+
+* CHAR
+* VARCHAR
+* TINYTEXT
+* MEDIUMTEXT
+* LONGTEXT
+* TEXT
+* ENUM
+* SET
+* DECIMAL (may exceed float precision)
+* BIGINT (may exceed float precision)
+* TIME (could be mapped to Date, but what date would be set?)
+* GEOMETRY (never used those, get in touch if you do)
+
+It is not recommended (and may go away / change in the future) to disable type
+casting, but you can currently do so on either the connection:
+
+```js
+var connection = require('mysql').createConnection({typeCast: false});
+```
+
+Or on the query level:
+
+```js
+var options = {sql: '...', typeCast: false};
+var query = connection.query(options, function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+```
+
+You can also pass a function and handle type casting yourself. You're given some
+column information like database, table and name and also type and length. If you
+just want to apply a custom type casting to a specific type you can do it and then
+fallback to the default. Here's an example of converting `TINYINT(1)` to boolean:
+
+```js
+connection.query({
+  sql: '...',
+  typeCast: function (field, next) {
+    if (field.type == 'TINY' && field.length == 1) {
+      return (field.string() == '1'); // 1 = true, 0 = false
+    }
+    return next();
+  }
+});
+```
+__WARNING: YOU MUST INVOKE the parser using one of these three field functions in your custom typeCast callback. They can only be called once. (see [#539](https://github.com/mysqljs/mysql/issues/539) for discussion)__
+
+```
+field.string()
+field.buffer()
+field.geometry()
+```
+are aliases for
+```
+parser.parseLengthCodedString()
+parser.parseLengthCodedBuffer()
+parser.parseGeometryValue()
+```
+__You can find which field function you need to use by looking at: [RowDataPacket.prototype._typeCast](https://github.com/mysqljs/mysql/blob/master/lib/protocol/packets/RowDataPacket.js#L41)__
+
+
+## Connection Flags
+
+If, for any reason, you would like to change the default connection flags, you
+can use the connection option `flags`. Pass a string with a comma separated list
+of items to add to the default flags. If you don't want a default flag to be used
+prepend the flag with a minus sign. To add a flag that is not in the default list,
+just write the flag name, or prefix it with a plus (case insensitive).
+
+**Please note that some available flags that are not supported (e.g.: Compression),
+are still not allowed to be specified.**
+
+### Example
+
+The next example blacklists FOUND_ROWS flag from default connection flags.
+
+```js
+var connection = mysql.createConnection("mysql://localhost/test?flags=-FOUND_ROWS");
+```
+
+### Default Flags
+
+The following flags are sent by default on a new connection:
+
+- `CONNECT_WITH_DB` - Ability to specify the database on connection.
+- `FOUND_ROWS` - Send the found rows instead of the affected rows as `affectedRows`.
+- `IGNORE_SIGPIPE` - Old; no effect.
+- `IGNORE_SPACE` - Let the parser ignore spaces before the `(` in queries.
+- `LOCAL_FILES` - Can use `LOAD DATA LOCAL`.
+- `LONG_FLAG`
+- `LONG_PASSWORD` - Use the improved version of Old Password Authentication.
+- `MULTI_RESULTS` - Can handle multiple resultsets for COM_QUERY.
+- `ODBC` Old; no effect.
+- `PROTOCOL_41` - Uses the 4.1 protocol.
+- `PS_MULTI_RESULTS` - Can handle multiple resultsets for COM_STMT_EXECUTE.
+- `RESERVED` - Old flag for the 4.1 protocol.
+- `SECURE_CONNECTION` - Support native 4.1 authentication.
+- `TRANSACTIONS` - Asks for the transaction status flags.
+
+In addition, the following flag will be sent if the option `multipleStatements`
+is set to `true`:
+
+- `MULTI_STATEMENTS` - The client may send multiple statement per query or
+  statement prepare.
+
+### Other Available Flags
+
+There are other flags available. They may or may not function, but are still
+available to specify.
+
+- COMPRESS
+- INTERACTIVE
+- NO_SCHEMA
+- PLUGIN_AUTH
+- REMEMBER_OPTIONS
+- SSL
+- SSL_VERIFY_SERVER_CERT
+
+## Debugging and reporting problems
+
+If you are running into problems, one thing that may help is enabling the
+`debug` mode for the connection:
+
+```js
+var connection = mysql.createConnection({debug: true});
+```
+
+This will print all incoming and outgoing packets on stdout. You can also restrict debugging to
+packet types by passing an array of types to debug:
+
+```js
+var connection = mysql.createConnection({debug: ['ComQueryPacket', 'RowDataPacket']});
+```
+
+to restrict debugging to the query and data packets.
+
+If that does not help, feel free to open a GitHub issue. A good GitHub issue
+will have:
+
+* The minimal amount of code required to reproduce the problem (if possible)
+* As much debugging output and information about your environment (mysql
+  version, node version, os, etc.) as you can gather.
+
+## Contributing
+
+This project welcomes contributions from the community. Contributions are
+accepted using GitHub pull requests. If you're not familiar with making
+GitHub pull requests, please refer to the
+[GitHub documentation "Creating a pull request"](https://help.github.com/articles/creating-a-pull-request/).
+
+For a good pull request, we ask you provide the following:
+
+1. Try to include a clear description of your pull request in the description.
+   It should include the basic "what" and "why"s for the request.
+2. The tests should pass as best as you can. See the [Running tests](#running-tests)
+   section on hwo to run the different tests. GitHub will automatically run
+   the tests as well, to act as a safety net.
+3. The pull request should include tests for the change. A new feature should
+   have tests for the new feature and bug fixes should include a test that fails
+   without the corresponding code change and passes after they are applied.
+   The command `npm run test-cov` will generate a `coverage/` folder that
+   contains HTML pages of the code coverage, to better understand if everything
+   you're adding is being tested.
+4. If the pull request is a new feature, please be sure to include all
+   appropriate documentation additions in the `Readme.md` file as well.
+5. To help ensure that your code is similar in style to the existing code,
+   run the command `npm run lint` and fix any displayed issues.
+
+## Running tests
+
+The test suite is split into two parts: unit tests and integration tests.
+The unit tests run on any machine while the integration tests require a
+MySQL server instance to be setup.
+
+### Running unit tests
+
+```sh
+$ FILTER=unit npm test
+```
+
+### Running integration tests
+
+Set the environment variables `MYSQL_DATABASE`, `MYSQL_HOST`, `MYSQL_PORT`,
+`MYSQL_USER` and `MYSQL_PASSWORD`. `MYSQL_SOCKET` can also be used in place
+of `MYSQL_HOST` and `MYSQL_PORT` to connect over a UNIX socket. Then run
+`npm test`.
+
+For example, if you have an installation of mysql running on localhost:3306
+and no password set for the `root` user, run:
+
+```sh
+$ mysql -u root -e "CREATE DATABASE IF NOT EXISTS node_mysql_test"
+$ MYSQL_HOST=localhost MYSQL_PORT=3306 MYSQL_DATABASE=node_mysql_test MYSQL_USER=root MYSQL_PASSWORD= FILTER=integration npm test
+```
+
+## Todo
+
+* Prepared statements
+* Support for encodings other than UTF-8 / ASCII

student/node_modules/readable-stream/GOVERNANCE.md

+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited.  There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting.  This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions.  If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer.  If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus.  See
+"WG Membership" above.

+
+***Node-core streams for userland***
+
+This package is a mirror of the Streams2 and Streams3 implementations in
+Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.1.3/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.

+* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
+
+## Minutes
+
+### adopt a charter
+
+* group: +1's all around
+
+### What versioning scheme should be adopted?
+* group: +1’s 3.0.0
+* domenic+group: pulling in patches from other sources where appropriate
+* mikeal: version independently, suggesting versions for io.js
+* mikeal+domenic: work with TC to notify in advance of changes
+simpler stream creation
+
+### streamline creation of streams
+* sam: streamline creation of streams
+* domenic: nice simple solution posted
+  but, we lose the opportunity to change the model
+  may not be backwards incompatible (double check keys)
+
+  **action item:** domenic will check
+
+### remove implicit flowing of streams on(‘data’)
+* add isFlowing / isPaused
+* mikeal: worrying that we’re documenting polyfill methods – confuses users
+* domenic: more reflective API is probably good, with warning labels for users
+* new section for mad scientists (reflective stream access)
+* calvin: name the “third state”
+* mikeal: maybe borrow the name from whatwg?
+* domenic: we’re missing the “third state”
+* consensus: kind of difficult to name the third state
+* mikeal: figure out differences in states / compat
+* mathias: always flow on data – eliminates third state
+  * explore what it breaks
+
+**action items:**
+* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
+* ask rod/build for infrastructure
+* **chris**: explore the “flow on data” approach
+* add isPaused/isFlowing
+* add new docs section
+* move isPaused to that section

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  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.

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+
+## Related links
+
+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. 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.

+
+Simple SQL escape and format for MySQL
+
+## Install
+
+```sh
+$ npm install sqlstring
+```
+
+## Usage
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var SqlString = require('sqlstring');
+```
+
+### Escaping query values
+
+**Caution** These methods of escaping values only works when the
+[NO_BACKSLASH_ESCAPES](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html#sqlmode_no_backslash_escapes)
+SQL mode is disabled (which is the default state for MySQL servers).
+
+In order to avoid SQL Injection attacks, you should always escape any user
+provided data before using it inside a SQL query. You can do so using the
+`SqlString.escape()` method:
+
+```js
+var userId = 'some user provided value';
+var sql    = 'SELECT * FROM users WHERE id = ' + SqlString.escape(userId);
+console.log(sql); // SELECT * FROM users WHERE id = 'some user provided value'
+```
+
+Alternatively, you can use `?` characters as placeholders for values you would
+like to have escaped like this:
+
+```js
+var userId = 1;
+var sql    = SqlString.format('SELECT * FROM users WHERE id = ?', [userId]);
+console.log(sql); // SELECT * FROM users WHERE id = 1
+```
+
+Multiple placeholders are mapped to values in the same order as passed. For example,
+in the following query `foo` equals `a`, `bar` equals `b`, `baz` equals `c`, and
+`id` will be `userId`:
+
+```js
+var userId = 1;
+var sql    = SqlString.format('UPDATE users SET foo = ?, bar = ?, baz = ? WHERE id = ?',
+  ['a', 'b', 'c', userId]);
+console.log(sql); // UPDATE users SET foo = 'a', bar = 'b', baz = 'c' WHERE id = 1
+```
+
+This looks similar to prepared statements in MySQL, however it really just uses
+the same `SqlString.escape()` method internally.
+
+**Caution** This also differs from prepared statements in that all `?` are
+replaced, even those contained in comments and strings.
+
+Different value types are escaped differently, here is how:
+
+* Numbers are left untouched
+* Booleans are converted to `true` / `false`
+* Date objects are converted to `'YYYY-mm-dd HH:ii:ss'` strings
+* Buffers are converted to hex strings, e.g. `X'0fa5'`
+* Strings are safely escaped
+* Arrays are turned into list, e.g. `['a', 'b']` turns into `'a', 'b'`
+* Nested arrays are turned into grouped lists (for bulk inserts), e.g. `[['a',
+  'b'], ['c', 'd']]` turns into `('a', 'b'), ('c', 'd')`
+* Objects that have a `toSqlString` method will have `.toSqlString()` called
+  and the returned value is used as the raw SQL.
+* Objects are turned into `key = 'val'` pairs for each enumerable property on
+  the object. If the property's value is a function, it is skipped; if the
+  property's value is an object, toString() is called on it and the returned
+  value is used.
+* `undefined` / `null` are converted to `NULL`
+* `NaN` / `Infinity` are left as-is. MySQL does not support these, and trying
+  to insert them as values will trigger MySQL errors until they implement
+  support.
+
+You may have noticed that this escaping allows you to do neat things like this:
+
+```js
+var post  = {id: 1, title: 'Hello MySQL'};
+var sql = SqlString.format('INSERT INTO posts SET ?', post);
+console.log(sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'
+```
+
+And the `toSqlString` method allows you to form complex queries with functions:
+
+```js
+var CURRENT_TIMESTAMP = { toSqlString: function() { return 'CURRENT_TIMESTAMP()'; } };
+var sql = SqlString.format('UPDATE posts SET modified = ? WHERE id = ?', [CURRENT_TIMESTAMP, 42]);
+console.log(sql); // UPDATE posts SET modified = CURRENT_TIMESTAMP() WHERE id = 42
+```
+
+To generate objects with a `toSqlString` method, the `SqlString.raw()` method can
+be used. This creates an object that will be left un-touched when using in a `?`
+placeholder, useful for using functions as dynamic values:
+
+**Caution** The string provided to `SqlString.raw()` will skip all escaping
+functions when used, so be careful when passing in unvalidated input.
+
+```js
+var CURRENT_TIMESTAMP = SqlString.raw('CURRENT_TIMESTAMP()');
+var sql = SqlString.format('UPDATE posts SET modified = ? WHERE id = ?', [CURRENT_TIMESTAMP, 42]);
+console.log(sql); // UPDATE posts SET modified = CURRENT_TIMESTAMP() WHERE id = 42
+```
+
+If you feel the need to escape queries by yourself, you can also use the escaping
+function directly:
+
+```js
+var sql = 'SELECT * FROM posts WHERE title=' + SqlString.escape('Hello MySQL');
+console.log(sql); // SELECT * FROM posts WHERE title='Hello MySQL'
+```
+
+### Escaping query identifiers
+
+If you can't trust an SQL identifier (database / table / column name) because it is
+provided by a user, you should escape it with `SqlString.escapeId(identifier)` like this:
+
+```js
+var sorter = 'date';
+var sql    = 'SELECT * FROM posts ORDER BY ' + SqlString.escapeId(sorter);
+console.log(sql); // SELECT * FROM posts ORDER BY `date`
+```
+
+It also supports adding qualified identifiers. It will escape both parts.
+
+```js
+var sorter = 'date';
+var sql    = 'SELECT * FROM posts ORDER BY ' + SqlString.escapeId('posts.' + sorter);
+console.log(sql); // SELECT * FROM posts ORDER BY `posts`.`date`
+```
+
+If you do not want to treat `.` as qualified identifiers, you can set the second
+argument to `true` in order to keep the string as a literal identifier:
+
+```js
+var sorter = 'date.2';
+var sql    = 'SELECT * FROM posts ORDER BY ' + SqlString.escapeId(sorter, true);
+console.log(sql); // SELECT * FROM posts ORDER BY `date.2`
+```
+
+Alternatively, you can use `??` characters as placeholders for identifiers you would
+like to have escaped like this:
+
+```js
+var userId = 1;
+var columns = ['username', 'email'];
+var sql     = SqlString.format('SELECT ?? FROM ?? WHERE id = ?', [columns, 'users', userId]);
+console.log(sql); // SELECT `username`, `email` FROM `users` WHERE id = 1
+```
+**Please note that this last character sequence is experimental and syntax might change**
+
+When you pass an Object to `.escape()` or `.format()`, `.escapeId()` is used to avoid SQL injection in object keys.
+
+### Formatting queries
+
+You can use `SqlString.format` to prepare a query with multiple insertion points,
+utilizing the proper escaping for ids and values. A simple example of this follows:
+
+```js
+var userId  = 1;
+var inserts = ['users', 'id', userId];
+var sql     = SqlString.format('SELECT * FROM ?? WHERE ?? = ?', inserts);
+console.log(sql); // SELECT * FROM `users` WHERE `id` = 1
+```
+
+Following this you then have a valid, escaped query that you can then send to the database safely.
+This is useful if you are looking to prepare the query before actually sending it to the database.
+You also have the option (but are not required) to pass in `stringifyObject` and `timeZone`,
+allowing you provide a custom means of turning objects into strings, as well as a
+location-specific/timezone-aware `Date`.
+
+This can be further combined with the `SqlString.raw()` helper to generate SQL
+that includes MySQL functions as dynamic vales:
+
+```js
+var userId = 1;
+var data   = { email: 'foobar@example.com', modified: SqlString.raw('NOW()') };
+var sql    = SqlString.format('UPDATE ?? SET ? WHERE `id` = ?', ['users', data, userId]);
+console.log(sql); // UPDATE `users` SET `email` = 'foobar@example.com', `modified` = NOW() WHERE `id` = 1
+```

+***Node-core string_decoderstring_decoder for userland***
+
+This package is a mirror of the string_decoder implementation in Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v7.8.0/docs/api/).
+
+As of version 1.0.0 **string_decoder** uses semantic versioning.
+
+## Previous versions
+
+Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
+
+## Update
+
+The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.

+util-deprecate
+==============
+### The Node.js `util.deprecate()` function with browser support
+
+In Node.js, this module simply re-exports the `util.deprecate()` function.
+
+In the web browser (i.e. via browserify), a browser-specific implementation
+of the `util.deprecate()` function is used.
+
+
+## API
+
+A `deprecate()` function is the only thing exposed by this module.
+
+``` javascript
+// setup:
+exports.foo = deprecate(foo, 'foo() is deprecated, use bar() instead');
+
+
