mDNS Documentation
What is mDNS?
mDNS stands for Multicast Domain Name System. It's function is to resolve host names to IP addresses within small networkds that do not include a local name server. It is a zero-configuration service, using essentially the same programming interfaces, packet formats and operating semantics as the unicast Domain Name System (DNS). Although mDNS is designed to be stand-alone capable, it can work in concert with unicast DNS servers.
Full documentation of the protocol is located at: https://tools.ietf.org/html/rfc6762
Other helpful topics and documents:
- Zero Configuration Networking: https://tools.ietf.org/html/rfc6762#ref-Zeroconf
- Automatic link-local addressing: https://tools.ietf.org/html/rfc3927
https://tools.ietf.org/html/rfc4862
DNS-format messages contain a header, a Question Section, then Answer, Authority, and additional Record Sections. The Answer, Authority, and Additional Record Sections all hold resource records.
mDNS is a datagram protocal that uses broadcast mode and membership groups.
What does mDNS in the Daplie System?
We are sending messages back and forth on a network that searches for any other mDNS compatible devices and asks that device if it is connected to a router or WiFi with a Daplie-compatible Cloud device.
If it is a Daplie-compatible Cloud device, then it will reply to the sender with some sort of confirmation.
Terms:
TTL - IP Time to Live - located in IP header of the DNS packet and is used effectively as a hop-count limit for the packet, to guard against routing loops
"shared" resource record set is where several Multicast DNS responders may have records with the same name, rrtype, and rrclass, and several responders may respond to a particular query
"unique" resource record set is one where all the records with that name, rrtype, and rrclass are conceptually under the control or ownership of a single responder, and it is expected that at most one responder should respond to a query for that name, rrtype, and rrclass. Before claiming ownership of a unique resource record set, a responder MUST probe to verify that no other responder already claims ownership. (For fault-tolerance and other reasons, sometimes it is permissible to have more than one responder answering for a particular "unique" resource record set, but such cooperating resoinders MUST give answers containing identical rdata for these records. If they do not give answers containing identical rdata, then the probing stop will reject the data as being inconsistent with what is already being advertised on the network for these names.)
Multicast DNS Names
A host that belongs to an organization or individual who has control over some potion of the DNS namespace can be assigned a globally unique name within that portion of th DNS namespace, such as, "chechire.example.com". For those of us who have this luxury, this works very well. However, the mojority of home computer users do not have easy access to any portion of the global DNS namespace within which they have the authoriry to create names. This leaves the majority of home computers effectively anonymous for practical purposes

# assert-plus Changelog
## 1.0.0
- *BREAKING* assert.number (and derivatives) now accept Infinity as valid input
- Add assert.finite check. Previous assert.number callers should use this if
they expect Infinity inputs to throw.
## 0.2.0
- Fix `assert.object(null)` so it throws
- Fix optional/arrayOf exports for non-type-of asserts
- Add optiona/arrayOf exports for Stream/Date/Regex/uuid
- Add basic unit test coverage

# assert-plus
This library is a super small wrapper over node's assert module that has two
things: (1) the ability to disable assertions with the environment variable
NODE\_NDEBUG, and (2) some API wrappers for argument testing. Like
`assert.string(myArg, 'myArg')`. As a simple example, most of my code looks
like this:
```javascript
var assert = require('assert-plus');
function fooAccount(options, callback) {
assert.object(options, 'options');
assert.number(options.id, 'options.id');
assert.bool(options.isManager, 'options.isManager');
assert.string(options.name, 'options.name');
assert.arrayOfString(options.email, 'options.email');
assert.func(callback, 'callback');
// Do stuff
callback(null, {});
}
```
# API
All methods that *aren't* part of node's core assert API are simply assumed to
take an argument, and then a string 'name' that's not a message; `AssertionError`
will be thrown if the assertion fails with a message like:
AssertionError: foo (string) is required
at test (/home/mark/work/foo/foo.js:3:9)
at Object.<anonymous> (/home/mark/work/foo/foo.js:15:1)
at Module._compile (module.js:446:26)
at Object..js (module.js:464:10)
at Module.load (module.js:353:31)
at Function._load (module.js:311:12)
at Array.0 (module.js:484:10)
at EventEmitter._tickCallback (node.js:190:38)
from:
```javascript
function test(foo) {
assert.string(foo, 'foo');
}
```
There you go. You can check that arrays are of a homogeneous type with `Arrayof$Type`:
```javascript
function test(foo) {
assert.arrayOfString(foo, 'foo');
}
```
You can assert IFF an argument is not `undefined` (i.e., an optional arg):
```javascript
assert.optionalString(foo, 'foo');
```
Lastly, you can opt-out of assertion checking altogether by setting the
environment variable `NODE_NDEBUG=1`. This is pseudo-useful if you have
lots of assertions, and don't want to pay `typeof ()` taxes to v8 in
production. Be advised: The standard functions re-exported from `assert` are
also disabled in assert-plus if NDEBUG is specified. Using them directly from
the `assert` module avoids this behavior.
The complete list of APIs is:
* assert.array
* assert.bool
* assert.buffer
* assert.func
* assert.number
* assert.finite
* assert.object
* assert.string
* assert.stream
* assert.date

* assert.optionalArrayOfString
* assert.optionalArrayOfStream

BinaryHeap
==========
Basic binary heap tree using linked lists
Usage
-----
```javascript
var BinaryHeap = require('binaryheap');
var heap = new BinaryHeap();
var a = [6, 5, 3, 1, 8, 7, 2, 4];
a.forEach(function (k) {
heap.insert({ value: k }, k);
});
heap.print();
while (heap.length) {
console.log('popping', heap.pop().value);
}
```
By default it stores as a max-heap, if you pass truthy to the constructor though
it will behave as a min-heap.
Methods
-------
* `insert(obj, key)` -- obj can be any new or existing object, and key is any
value that behaves sanely with `>` or `<`
* `pop()` -- removes and returns the maximum or minimum object from the root
of the heap
* `remove(obj)` -- removes a previously inserted object from the heap
* `print()` -- mostly for debugging purposes prints a graphviz dot style
digraph to confirm ordering
Members
-------
* `length` -- number of objects currently in the heap

BufferCursor
============
This is a simple module that allows you to traverse a Buffer iteratively. You
can read and write different types and the cursor's position will update with
the proper size, which you can see through `.tell()` you can also
`.seek()`
```javascript
var bc = new BufferCursor(buffer);
bc.readUInt16BE();
bc.readUInt8();
bc.readUInt32BE();
console.log(bc.tell());
```
Will output `7`
Methods
-------
For the most part `BufferCursor` and `Buffer` share the same methods, there's
just a slight alteration in method signature, none of the methods take an
offset.
So `.readUInt16LE(10)` in `Buffer` is equivalent to `bs.seek(10); bs.readUInt16LE();`
All `read[U]Int` and `write[U]Int` methods are reproduced, as are `toString`,
`write`, `fill`, and `slice`. All of these methods will move the cursor through
the stream and do not take an offset parameter, where an `end` parameter would
normaly be used, here you supply a `length`.
The following are additional methods:
* `seek(value)` -- Seek to an arbitrary position in the stream
* `tell()` -- Return the current location in the stream
* `eof()` -- Return true if at the end of the stream
* `toByteArray([method])` -- This is a special helper method which will return
the *entire* stream (i.e. from the start) as an array of numbers.
- By default it will use `readUInt8` but you can pass in any
`read[U]Int[8,16,32][LE,BE]` to change what the array is made of
Properties
----------
* `.buffer` -- Access to the raw buffer
* `.length` -- The size of the buffer

# debug
[![Build Status](https://travis-ci.org/visionmedia/debug.svg?branch=master)](https://travis-ci.org/visionmedia/debug) [![Coverage Status](https://coveralls.io/repos/github/visionmedia/debug/badge.svg?branch=master)](https://coveralls.io/github/visionmedia/debug?branch=master)
A tiny node.js debugging utility modelled after node core's debugging technique.
**Discussion around the V3 API is under way [here](https://github.com/visionmedia/debug/issues/370)**
## Installation
```bash
$ npm install debug
```
## Usage
`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
Example _app.js_:
```js
var debug = require('debug')('http')
, http = require('http')
, name = 'My App';
// fake app
debug('booting %s', name);
http.createServer(function(req, res){
debug(req.method + ' ' + req.url);
res.end('hello\n');
}).listen(3000, function(){
debug('listening');
});
// fake worker of some kind
require('./worker');
```
Example _worker.js_:
```js
var debug = require('debug')('worker');
setInterval(function(){
debug('doing some work');
}, 1000);
```
The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
#### Windows note
On Windows the environment variable is set using the `set` command.
```cmd
set DEBUG=*,-not_this
```
Note that PowerShell uses different syntax to set environment variables.
```cmd
$env:DEBUG = "*,-not_this"
```
Then, run the program to be debugged as usual.
## Millisecond diff
When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
## Conventions
If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
## Wildcards
The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
## Environment Variables
When running through Node.js, you can set a few environment variables that will
change the behavior of the debug logging:
| Name | Purpose |
|-----------|-------------------------------------------------|
| `DEBUG` | Enables/disabled specific debugging namespaces. |
| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
| `DEBUG_DEPTH` | Object inspection depth. |
| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
__Note:__ The environment variables beginning with `DEBUG_` end up being
converted into an Options object that gets used with `%o`/`%O` formatters.
See the Node.js documentation for
[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
for the complete list.
## Formatters
Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters:
| Formatter | Representation |
|-----------|----------------|
| `%O` | Pretty-print an Object on multiple lines. |
| `%o` | Pretty-print an Object all on a single line. |
| `%s` | String. |
| `%d` | Number (both integer and float). |
| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
| `%%` | Single percent sign ('%'). This does not consume an argument. |
### Custom formatters
You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like:
```js
const createDebug = require('debug')
createDebug.formatters.h = (v) => {
return v.toString('hex')
}
// …elsewhere
const debug = createDebug('foo')
debug('this is hex: %h', new Buffer('hello world'))
// foo this is hex: 68656c6c6f20776f726c6421 +0ms
```
## Browser support
You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
if you don't want to build it yourself.
Debug's enable state is currently persisted by `localStorage`.
Consider the situation shown below where you have `worker:a` and `worker:b`,
and wish to debug both. You can enable this using `localStorage.debug`:
```js
localStorage.debug = 'worker:*'
```
And then refresh the page.
```js
a = debug('worker:a');
b = debug('worker:b');
setInterval(function(){
a('doing some work');
}, 1000);
setInterval(function(){
b('doing some work');
}, 1200);
```
#### Web Inspector Colors
Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
option. These are WebKit web inspectors, Firefox ([since version
31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
and the Firebug plugin for Firefox (any version).
Colored output looks something like:

## Output streams
By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
Example _stdout.js_:
```js
var debug = require('debug');
var error = debug('app:error');
// by default stderr is used
error('goes to stderr!');
var log = debug('app:log');
// set this namespace to log via console.log
log.log = console.log.bind(console); // don't forget to bind to console!
log('goes to stdout');
error('still goes to stderr!');
// set all output to go via console.info
// overrides all per-namespace log settings
debug.log = console.info.bind(console);
error('now goes to stdout via console.info');
log('still goes to stdout, but via console.info now');
```

# debug
tiny node.js debugging utility modelled after node core's debugging technique.
## Installation
```bash
$ npm install debug
```
## Usage
With `debug` you simply invoke the exported function to generate your debug function, passing it a name which will determine if a noop function is returned, or a decorated `console.error`, so all of the `console` [format string goodies](https://developer.chrome.com/devtools/docs/console-api#consolelogobject-object) you're used to work fine. A unique color is selected per-function for visibility.
Example _app.js_:
```js
var debug = require('debug')('http')
, http = require('http')
, name = 'My App';
// fake app
debug('booting %s', name);
http.createServer(function(req, res){
debug(req.method + ' ' + req.url);
res.end('hello\n');
}).listen(3000, function(){
debug('listening');
});
// fake worker of some kind
require('./worker');
```
Example _worker.js_:
```js
var debug = require('debug')('worker');
setInterval(function(){
debug('doing some work');
}, 1000);
```
The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
#### Windows note
On Windows the environment variable is set using the `set` command.
```cmd
set DEBUG=*,-not_this
```
Note that PowerShell using different syntax to set environment variables.
```cmd
$env:DEBUG = "*,-not_this"
```
Then, run the program to be debugged as usual.

When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
## Conventions
If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
## Wildcards
The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
## Browser support
Debug works in the browser as well, currently persisted by `localStorage`. Consider the situation shown below where you have `worker:a` and `worker:b`, and wish to debug both. You can enable this using `localStorage.debug`:
```js
localStorage.debug = 'worker:*'
```
And then refresh the page.
```js
a = debug('worker:a');
b = debug('worker:b');
setInterval(function(){
a('doing some work');
}, 1000);
setInterval(function(){
b('doing some work');
}, 1200);
```
#### Web Inspector Colors
Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
option. These are WebKit web inspectors, Firefox ([since version
31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
and the Firebug plugin for Firefox (any version).
Colored output looks something like:

## Output streams
### stderr vs stdout
By default `debug` will log to stderr, however this can be changed by setting the environment variable `DEBUG_FD` to `1` for stdout and `2` for stderr (the default value).
You can also set an alternative logging method per-namespace by overriding the `log` method on a per-namespace or globally:
Example _stdout.js_:
```js
var debug = require('debug');
var error = debug('app:error');
// by default stderr is used
error('goes to stderr!');
var log = debug('app:log');
// set this namespace to log via console.log
log.log = console.log.bind(console); // don't forget to bind to console!
log('goes to stdout');
error('still goes to stderr!');
// set all output to go via console.info
// overrides all per-namespace log settings
debug.log = console.info.bind(console);
error('now goes to stdout via console.info');
log('still goes to stdout, but via console.info now');
```
### Save debug output to a file
You can save all debug statements to a file by piping them.
Example:
```bash
$ DEBUG_FD=3 node your-app.js 3> whatever.log
```
### Terminal colors
By default colors will only be used in a TTY. However this can be overridden by setting the environment variable `DEBUG_COLORS` to `1`.
Note: Certain IDEs (such as WebStorm) don't support colors on stderr. In these cases you must set `DEBUG_COLORS` to `1` and additionally change `DEBUG_FD` to `1`.

mdns-js-packet
==============
[![Build Status](https://travis-ci.org/mdns-js/node-dns-js.svg?branch=master)](https://travis-ci.org/mdns-js/node-dns-js)
DNS packet parser specifically built for mdns-js
[mdns-js](https://github.com/kmpm/node-mdns-js)
but it should be generic enough to do general dns stuff.
NEW LOCATION
This project was moved into it's own organisation. Please update any git remotes you might have pointing here.
git remote set-url origin https://github.com/mdns-js/node-dns-js.git
You probably want to have a look at
[native-dns-packet](https://github.com/tjfontaine/native-dns-packet)
first and if that does do what you need, you might start looking at this.
mdns-js-packet should produce the same output as native-dns-packet,
it even uses it's test fixtures and borrows some parts of it.
This was made before i knew about native-dns-packet but since that
still has some bugs in handling some mDNS packets I cant use it.
example
-------
```javascript
var dns = require('dns-js');
/*some code that will get you a dns message buffer*/
var result = dns.DNSPacket.parse(message);
console.log(result);
```
Look at examples/dnsresolver.js for a more detailed example.
Contribute
----------
I will gladly accept any contributions as pull requests.
Just run __npm run lint__ on the code first so that the coding style
is kept somewhat consistent.
I miss doing this myself from time to time and I won't go ballistic if anyone
else forget but I would really appreciate it.
