 ## Pooling connections
 
-Use pool directly.
+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).
+
+Create a pool and use it directly:
+
 ```js
 var mysql = require('mysql');
 var pool  = mysql.createPool({
   connectionLimit : 10,
   host            : 'example.org',
   user            : 'bob',

-
-  console.log('The solution is: ', rows[0].solution);
+  password        : 'secret',
+  database        : 'my_db'
 });
-```
-
-Connections can be pooled to ease sharing a single connection, or managing
-multiple connections.

-var pool  = mysql.createPool({
-  host     : 'example.org',

+  console.log('The solution is: ', results[0].solution);
 });
 ```
 
-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.
+This is a shortcut for the `pool.getConnection()` -> `connection.query()` ->
+`connection.release()` code flow. Using `pool.getConnection()` is useful to

+### Custom type casting
+
 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:
+fallback to the default.
+
+The function is provided two arguments `field` and `next` and is expected to
+return the value for the given field by invoking the parser functions through
+the `field` object.
+
+The `field` argument is a `Field` object and contains data about the field that
+need to be parsed. The following are some of the properties on a `Field` object:
+
+  * `db` - a string of the database the field came from.
+  * `table` - a string of the table the field came from.
+  * `name` - a string of the field name.
+  * `type` - a string of the field type in all caps.
+  * `length` - a number of the field length, as given by the database.
+
+The `next` argument is a `function` that, when called, will return the default
+type conversaion for the given field.
+
+When getting the field data, the following helper methods are present on the
+`field` object:
+
+  * `.string()` - parse the field into a string.
+  * `.buffer()` - parse the field into a `Buffer`.
+  * `.geometry()` - parse the field as a geometry value.
+
+The MySQL protocol is a text-based protocol. This means that over the wire, all
+field types are represented as a string, which is why only string-like functions
+are available on the `field` object. Based on the type information (like `INT`),
+the type cast should convert the string field into a different JavaScript type
+(like a `number`).
+
+Here's an example of converting `TINYINT(1)` to boolean:
 
 ```js
-connection.query({
-  sql: '...',
+connection = mysql.createConnection({
   typeCast: function (field, next) {
-    if (field.type == 'TINY' && field.length == 1) {
-      return (field.string() == '1'); // 1 = true, 0 = false
+    if (field.type === 'TINY' && field.length === 1) {
+      return (field.string() === '1'); // 1 = true, 0 = false
+    } else {
+      return next();
     }
-    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 for discussion)__

-field.string()
-field.buffer()
-field.geometry()
-```
-are aliases for
-```
-parser.parseLengthCodedString()
-parser.parseLengthCodedBuffer()

-```
-__You can find which field function you need to use by looking at: [RowDataPacket.prototype._typeCast](https://github.com/felixge/node-mysql/blob/master/lib/protocol/packets/RowDataPacket.js#L41)__

+## Security issues
+
+Security issues should not be first reported through GitHub or another public
+forum, but kept private in order for the collaborators to assess the report
+and either (a) devise a fix and plan a release date or (b) assert that it is
+not a security issue (in which case it can be posted in a public forum, like
+a GitHub issue).
+
+The primary private forum is email, either by emailing the module's author or
+opening a GitHub issue simply asking to whom a security issues should be
+addressed to without disclosing the issue or type of issue.
+
+An ideal report would include a clear indication of what the security issue is
+and how it would be exploited, ideally with an accompanying proof of concept
+("PoC") for collaborators to work against and validate potentional fixes against.
+
+## 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 how 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.

-***Node-core streams for userland***

-[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true&downloadRank=true)](https://nodei.co/npm/readable-stream/)
-[![NPM](https://nodei.co/npm-dl/readable-stream.png&months=6&height=3)](https://nodei.co/npm/readable-stream/)
-
-This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
-
-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.
-
-**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
-
-**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+### 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/v8.11.1/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.

+## Agenda
+
+Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
+
+* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
+* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)
+* simpler stream creation [#102](https://github.com/iojs/readable-stream/issues/102)
+* 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
+

+#### 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)
+
+
+* `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]])
+
+
+* `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: 
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: 
+```
+
+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)
+
+
+* `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])
+
+
+* `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]])
+
+
+* `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);
+  // 
+```
+
+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);
+  // 
+```
+
+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);
+  // 
+```
+
+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)
+
+
+* `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);
+  // 
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // 
+```
+
+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)
+
+
+* `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
+
+
+
+```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 v8.9.4 string_decoder for userland***
+
+
+[![NPM](https://nodei.co/npm/string_decoder.png?downloads=true&downloadRank=true)](https://nodei.co/npm/string_decoder/)
+[![NPM](https://nodei.co/npm-dl/string_decoder.png?&months=6&height=3)](https://nodei.co/npm/string_decoder/)
+
+
+```bash
+npm install --save string_decoder
+```
+
+***Node-core string_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/v8.9.4/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.
+
+## Streams Working Group
+
+`string_decoder` 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.
+
+See [readable-stream](https://github.com/nodejs/readable-stream) for
+more details.

+==============
+### 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');
+
+
+// users see:
+foo();
+// foo() is deprecated, use bar() instead
+foo();
+foo();
+```
