How to contribute to noVNC
==========================
We accept code via pull requests on GitHub. There are several guidelines that
we expect contributors submitting code requests to follow. If you have issues
following any of these guidelines, feel free to drop us a line by leaving a
comment in the code request or sending us an email.
Contributing Guidelines
-----------------------
* While we don't have an official coding style guide, please try to follow
the general coding style of the existing code.
** Use four spaces instead of tabs
** prefix private variables and functions with an `_`
* Please try to include unit tests for your code. For instance, if you
introduce a new encoding, add a test to `tests/test.rfb.js` under the
"Encoding Handlers" section (basically, input a small pattern in your
encoding and make sure the pattern gets displayed correctly). If you
fix a bug, try to add a unit test that would have caught that bug
(if possible -- some bugs, especially visual ones, are hard to test for).
* Squash your commits down in to a clean commit history. For instance, there
should not be "cleanup" commits where you fix issues in previous commits in
the same pull request. Before you go to commit, use `git rebase -i` to
squash these changes into the relevant commits. For instance, a good commit
history might look like "Added support for FOO encoding, Added support for
BAR message, Placed Button in UI to Trigger BAR" (where each comma denotes
a separate commit).
* Add both a title and description to your commit, if possible. Place more
detail on what you did in the description.
Running the unit tests
----------------------
There are two ways to run the unit tests. For both ways, you should first run
`npm install` (not as root).
The first way to run the tests is to run `npm test`. This will run all the
tests in the headless PhantomJS browser (which uses WebKit).
The second way to run the tests is using the `tests/run_from_console.js` file.
This way is a bit more flexible, and can provide more information about what
went wrong. To run all the tests, simply run `tests/run_from_console.js`.
To run a specific test file, you can use the `-t path/to/test/file.js` option.
If you wish to simply generate the HTML for the test, use the `-g` option, and
the path to the temporary HTML file will be written to standard out. To open
this file in your default browser automatically, pass the `-o` option as well.
More information can be found by passing the `--help` or `-h` option.
Thanks, and happy coding!

#### Running noVNC
#### Running noVNC from Snap Directly
You can run the Snap-package installed novnc directly with, for example:
`novnc --listen 6081 --vnc localhost:5901 # /snap/bin/novnc if /snap/bin is not in your PATH`
#### Running as a Service (Daemon)
If you want to use certificate files, due to standard Snap confinement restrictions you need to have them in the /home/\<user\>/snap/novnc/current/ directory. If your username is jsmith an example command would be:
`novnc --listen 8443 --cert ~jsmith/snap/novnc/current/self.crt --key ~jsmith/snap/novnc/current/self.key --vnc ubuntu.example.com:5901`
#### Running noVNC from Snap as a Service (Daemon)
The Snap package also has the capability to run a 'novnc' service which can be
configured to listen on multiple ports connecting to multiple VNC servers
(effectively a service runing multiple instances of novnc).

# 1. Internal Modules
The noVNC client is composed of several internal modules that handle
rendering, input, networking, etc. Each of the modules is designed to
be cross-browser and independent from each other.
Note however that the API of these modules is not guaranteed to be
stable, and this documentation is not maintained as well as the
official external API.
## 1.1 Module List
* __Keyboard__ (core/input/keyboard.js): Keyboard input event handler with
non-US keyboard support. Translates keyDown and keyUp events to X11
keysym values.
* __Display__ (core/display.js): Efficient 2D rendering abstraction
layered on the HTML5 canvas element.
* __Websock__ (core/websock.js): Websock client from websockify
with transparent binary data support.
[Websock API](https://github.com/novnc/websockify-js/wiki/websock.js) wiki page.
## 1.2 Callbacks
For the Mouse, Keyboard and Display objects the callback functions are
assigned to configuration attributes, just as for the RFB object. The
WebSock module has a method named 'on' that takes two parameters: the
callback event name, and the callback function.

# noVNC API
The interface of the noVNC client consists of a single RFB object that
is instantiated once per connection.
## RFB
The `RFB` object represents a single connection to a VNC server. It
communicates using a WebSocket that must provide a standard RFB
protocol stream.
### Constructor
[`RFB()`](#rfb-1)
- Creates and returns a new `RFB` object.
### Properties
`viewOnly`
- Is a `boolean` indicating if any events (e.g. key presses or mouse
movement) should be prevented from being sent to the server.
Disabled by default.
`focusOnClick`
- Is a `boolean` indicating if keyboard focus should automatically be
moved to the remote session when a `mousedown` or `touchstart`
event is received. Enabled by default.
`clipViewport`
- Is a `boolean` indicating if the remote session should be clipped
to its container. When disabled scrollbars will be shown to handle
the resulting overflow. Disabled by default.
`dragViewport`
- Is a `boolean` indicating if mouse events should control the
relative position of a clipped remote session. Only relevant if
`clipViewport` is enabled. Disabled by default.
`scaleViewport`
- Is a `boolean` indicating if the remote session should be scaled
locally so it fits its container. When disabled it will be centered
if the remote session is smaller than its container, or handled
according to `clipViewport` if it is larger. Disabled by default.
`resizeSession`
- Is a `boolean` indicating if a request to resize the remote session
should be sent whenever the container changes dimensions. Disabled
by default.
`showDotCursor`
- Is a `boolean` indicating whether a dot cursor should be shown
instead of a zero-sized or fully-transparent cursor if the server
sets such invisible cursor. Disabled by default.
`background`
- Is a valid CSS [background](https://developer.mozilla.org/en-US/docs/Web/CSS/background)
style value indicating which background style should be applied
to the element containing the remote session screen. The default value is `rgb(40, 40, 40)`
(solid gray color).
`qualityLevel`
- Is an `int` in range `[0-9]` controlling the desired JPEG quality.
Value `0` implies low quality and `9` implies high quality.
Default value is `6`.
`compressionLevel`
- Is an `int` in range `[0-9]` controlling the desired compression
level. Value `0` means no compression. Level 1 uses a minimum of CPU
resources and achieves weak compression ratios, while level 9 offers
best compression but is slow in terms of CPU consumption on the server
side. Use high levels with very slow network connections.
Default value is `2`.
`capabilities` *Read only*
- Is an `Object` indicating which optional extensions are available
on the server. Some methods may only be called if the corresponding
capability is set. The following capabilities are defined:
| name | type | description
| -------- | --------- | -----------
| `power` | `boolean` | Machine power control is available
### Events
[`connect`](#connect)
- The `connect` event is fired when the `RFB` object has completed
the connection and handshaking with the server.
[`disconnect`](#disconnect)
- The `disconnect` event is fired when the `RFB` object disconnects.
[`serververification`](#serververification)
- The `serververification` event is fired when the server identity
must be confirmed by the user.
[`credentialsrequired`](#credentialsrequired)
- The `credentialsrequired` event is fired when more credentials must
be given to continue.
[`securityfailure`](#securityfailure)
- The `securityfailure` event is fired when the security negotiation
with the server fails.
[`clipboard`](#clipboard)
- The `clipboard` event is fired when clipboard data is received from
the server.
[`bell`](#bell)
- The `bell` event is fired when a audible bell request is received
from the server.
[`desktopname`](#desktopname)
- The `desktopname` event is fired when the remote desktop name
changes.
[`capabilities`](#capabilities)
- The `capabilities` event is fired when `RFB.capabilities` is
updated.
### Methods
[`RFB.disconnect()`](#rfbdisconnect)
- Disconnect from the server.
[`RFB.approveServer()`](#rfbapproveserver)
- Proceed connecting to the server. Should be called after the
[`serververification`](#serververification) event has fired and the
user has verified the identity of the server.
[`RFB.sendCredentials()`](#rfbsendcredentials)
- Send credentials to server. Should be called after the
[`credentialsrequired`](#credentialsrequired) event has fired.
[`RFB.sendKey()`](#rfbsendkey)
- Send a key event.
[`RFB.sendCtrlAltDel()`](#rfbsendctrlaltdel)
- Send Ctrl-Alt-Del key sequence.
[`RFB.focus()`](#rfbfocus)
- Move keyboard focus to the remote session.
[`RFB.blur()`](#rfbblur)
- Remove keyboard focus from the remote session.
[`RFB.machineShutdown()`](#rfbmachineshutdown)
- Request a shutdown of the remote machine.
[`RFB.machineReboot()`](#rfbmachinereboot)
- Request a reboot of the remote machine.
[`RFB.machineReset()`](#rfbmachinereset)
- Request a reset of the remote machine.
[`RFB.clipboardPasteFrom()`](#rfbclipboardpastefrom)
- Send clipboard contents to server.
### Details
#### RFB()
The `RFB()` constructor returns a new `RFB` object and initiates a new
connection to a specified VNC server.
##### Syntax
let rfb = new RFB( target, url [, options] );
###### Parameters
**`target`**
- A block [`HTMLElement`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement)
that specifies where the `RFB` object should attach itself. The
existing contents of the `HTMLElement` will be untouched, but new
elements will be added during the lifetime of the `RFB` object.
**`urlOrDataChannel`**
- A `DOMString` specifying the VNC server to connect to. This must be
a valid WebSocket URL. This can also be a `WebSocket` or `RTCDataChannel`.
**`options`** *Optional*
- An `Object` specifying extra details about how the connection
should be made.
Possible options:
`shared`
- A `boolean` indicating if the remote server should be shared or
if any other connected clients should be disconnected. Enabled
by default.
`credentials`
- An `Object` specifying the credentials to provide to the server
when authenticating. The following credentials are possible:
| name | type | description
| ------------ | ----------- | -----------
| `"username"` | `DOMString` | The user that authenticates
| `"password"` | `DOMString` | Password for the user
| `"target"` | `DOMString` | Target machine or session
`repeaterID`
- A `DOMString` specifying the ID to provide to any VNC repeater
encountered.
`wsProtocols`
- An `Array` of `DOMString`s specifying the sub-protocols to use
in the WebSocket connection. Empty by default.
#### connect
The `connect` event is fired after all the handshaking with the server
is completed and the connection is fully established. After this event
the `RFB` object is ready to recieve graphics updates and to send input.
#### disconnect
The `disconnect` event is fired when the connection has been
terminated. The `detail` property is an `Object` that contains the
property `clean`. `clean` is a `boolean` indicating if the termination
was clean or not. In the event of an unexpected termination or an error
`clean` will be set to false.
#### serververification
The `serververification` event is fired when the server provides
information that allows the user to verify that it is the correct server
and protect against a man-in-the-middle attack. The `detail` property is
an `Object` containing the property `type` which is a `DOMString`
specifying which type of information the server has provided. Other
properties are also available, depending on the value of `type`:
`"RSA"`
- The server identity is verified using just a RSA key. The property
`publickey` is a `Uint8Array` containing the public key in a unsigned
big endian representation.
#### credentialsrequired
The `credentialsrequired` event is fired when the server requests more
credentials than were specified to [`RFB()`](#rfb-1). The `detail`
property is an `Object` containing the property `types` which is an
`Array` of `DOMString` listing the credentials that are required.
#### securityfailure
The `securityfailure` event is fired when the handshaking process with
the server fails during the security negotiation step. The `detail`
property is an `Object` containing the following properties:
| Property | Type | Description
| -------- | ----------- | -----------
| `status` | `long` | The failure status code
| `reason` | `DOMString` | The **optional** reason for the failure
The property `status` corresponds to the
[SecurityResult](https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#securityresult)
status code in cases of failure. A status of zero will not be sent in
this event since that indicates a successful security handshaking
process. The optional property `reason` is provided by the server and
thus the language of the string is not known. However most servers will
probably send English strings. The server can choose to not send a
reason and in these cases the `reason` property will be omitted.
#### clipboard
The `clipboard` event is fired when the server has sent clipboard data.
The `detail` property is an `Object` containing the property `text`
which is a `DOMString` with the clipboard data.
#### bell
The `bell` event is fired when the server has requested an audible
bell.
#### desktopname
The `desktopname` event is fired when the name of the remote desktop
changes. The `detail` property is an `Object` with the property `name`
which is a `DOMString` specifying the new name.
#### capabilities
The `capabilities` event is fired whenever an entry is added or removed
from `RFB.capabilities`. The `detail` property is an `Object` with the
property `capabilities` containing the new value of `RFB.capabilities`.
#### RFB.disconnect()
The `RFB.disconnect()` method is used to disconnect from the currently
connected server.
##### Syntax
RFB.disconnect( );
#### RFB.approveServer()
The `RFB.approveServer()` method is used to signal that the user has
verified the server identity provided in a `serververification` event
and that the connection can continue.
##### Syntax
RFB.approveServer( );
#### RFB.sendCredentials()
The `RFB.sendCredentials()` method is used to provide the missing
credentials after a `credentialsrequired` event has been fired.
##### Syntax
RFB.sendCredentials( credentials );
###### Parameters
**`credentials`**
- An `Object` specifying the credentials to provide to the server
when authenticating. See [`RFB()`](#rfb-1) for details.
#### RFB.sendKey()
The `RFB.sendKey()` method is used to send a key event to the server.
##### Syntax
RFB.sendKey( keysym, code [, down] );
###### Parameters
**`keysym`**
- A `long` specifying the RFB keysym to send. Can be `0` if a valid
**`code`** is specified.
**`code`**
- A `DOMString` specifying the physical key to send. Valid values are
those that can be specified to
[`KeyboardEvent.code`](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/code).
If the physical key cannot be determined then `null` shall be
specified.
**`down`** *Optional*
- A `boolean` specifying if a press or a release event should be
sent. If omitted then both a press and release event are sent.
#### RFB.sendCtrlAltDel()
The `RFB.sendCtrlAltDel()` method is used to send the key sequence
*left Control*, *left Alt*, *Delete*. This is a convenience wrapper
around [`RFB.sendKey()`](#rfbsendkey).
##### Syntax
RFB.sendCtrlAltDel( );
#### RFB.focus()
The `RFB.focus()` method sets the keyboard focus on the remote session.
Keyboard events will be sent to the remote server after this point.
##### Syntax
RFB.focus( [options] );
###### Parameters
**`options`** *Optional*
- A `object` providing options to control how the focus will be
performed. Please see [`HTMLElement.focus()`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/focus)
for available options.
#### RFB.blur()
The `RFB.blur()` method remove keyboard focus on the remote session.
Keyboard events will no longer be sent to the remote server after this
point.
##### Syntax
RFB.blur( );
#### RFB.machineShutdown()
The `RFB.machineShutdown()` method is used to request to shut down the
remote machine. The capability `power` must be set for this method to
have any effect.
##### Syntax
RFB.machineShutdown( );
#### RFB.machineReboot()
The `RFB.machineReboot()` method is used to request a clean reboot of
the remote machine. The capability `power` must be set for this method
to have any effect.
##### Syntax
RFB.machineReboot( );
#### RFB.machineReset()
The `RFB.machineReset()` method is used to request a forced reset of
the remote machine. The capability `power` must be set for this method
to have any effect.
##### Syntax
RFB.machineReset( );
#### RFB.clipboardPasteFrom()
The `RFB.clipboardPasteFrom()` method is used to send clipboard data
to the remote server.
##### Syntax
RFB.clipboardPasteFrom( text );
###### Parameters
**`text`**
- A `DOMString` specifying the clipboard data to send.

# Embedding and Deploying noVNC Application
This document describes how to embed and deploy the noVNC application, which
includes settings and a full user interface. If you are looking for
documentation on how to use the core noVNC library in your own application,
then please see our [library documentation](LIBRARY.md).
## Files
The noVNC application consists of the following files and directories:
* `vnc.html` - The main page for the application and where users should go. It
is possible to rename this file.
* `app/` - Support files for the application. Contains code, images, styles and
translations.
* `core/` - The core noVNC library.
* `vendor/` - Third party support libraries used by the application and the
core library.
The most basic deployment consists of simply serving these files from a web
server and setting up a WebSocket proxy to the VNC server.
## Parameters
The noVNC application can be controlled by including certain settings in the
query string. Currently the following options are available:
* `autoconnect` - Automatically connect as soon as the page has finished
loading.
* `reconnect` - If noVNC should automatically reconnect if the connection is
dropped.
* `reconnect_delay` - How long to wait in milliseconds before attempting to
reconnect.
* `host` - The WebSocket host to connect to.
* `port` - The WebSocket port to connect to.
* `encrypt` - If TLS should be used for the WebSocket connection.
* `path` - The WebSocket path to use.
* `password` - The password sent to the server, if required.
* `repeaterID` - The repeater ID to use if a VNC repeater is detected.
* `shared` - If other VNC clients should be disconnected when noVNC connects.
* `bell` - If the keyboard bell should be enabled or not.
* `view_only` - If the remote session should be in non-interactive mode.
* `view_clip` - If the remote session should be clipped or use scrollbars if
it cannot fit in the browser.
* `resize` - How to resize the remote session if it is not the same size as
the browser window. Can be one of `off`, `scale` and `remote`.
* `quality` - The session JPEG quality level. Can be `0` to `9`.
* `compression` - The session compression level. Can be `0` to `9`.
* `show_dot` - If a dot cursor should be shown when the remote server provides
no local cursor, or provides a fully-transparent (invisible) cursor.
* `logging` - The console log level. Can be one of `error`, `warn`, `info` or
`debug`.
## HTTP Serving Considerations
### Browser Cache Issue
If you serve noVNC files using a web server that provides an ETag header, and
include any options in the query string, a nasty browser cache issue can bite
you on upgrade, resulting in a red error box. The issue is caused by a mismatch
between the new vnc.html (which is reloaded because the user has used it with
new query string after the upgrade) and the old javascript files (that the
browser reuses from its cache). To avoid this issue, the browser must be told
to always revalidate cached files using conditional requests. The correct
semantics are achieved via the (confusingly named) `Cache-Control: no-cache`
header that needs to be provided in the web server responses.
### Example Server Configurations
Apache:
```
# In the main configuration file
# (Debian/Ubuntu users: use "a2enmod headers" instead)
LoadModule headers_module modules/mod_headers.so
# In the <Directory> or <Location> block related to noVNC
Header set Cache-Control "no-cache"
```
Nginx:
```
# In the location block related to noVNC
add_header Cache-Control no-cache;
```

# Using the noVNC JavaScript library
This document describes how to make use of the noVNC JavaScript library for
integration in your own VNC client application. If you wish to embed the more
complete noVNC application with its included user interface then please see
our [embedding documentation](EMBEDDING.md).
## API
The API of noVNC consists of a single object called `RFB`. The formal
documentation for that object can be found in our [API documentation](API.md).
## Example
noVNC includes a small example application called `vnc_lite.html`. This does
not make use of all the features of noVNC, but is a good start to see how to
do things.
## Conversion of Modules
noVNC is written using ECMAScript 6 modules. This is not supported by older
versions of Node.js. To use noVNC with those older versions of Node.js the
library must first be converted.
Fortunately noVNC includes a script to handle this conversion. Please follow
the following steps:
1. Install Node.js
2. Run `npm install` in the noVNC directory
The result of the conversion is available in the `lib/` directory.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.

GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.
"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

* Websock: high-performance binary WebSockets
* Copyright (C) 2012 Joel Martin
* Licensed under MPL 2.0 (see LICENSE.txt)
*
* Websock is similar to the standard WebSocket object but Websock
* enables communication with raw TCP sockets (i.e. the binary stream)
* via websockify. This is accomplished by base64 encoding the data
* stream between Websock and websockify.
*
* Websock has built-in receive queue buffering; the message event
* does not contain actual data but is simply a notification that
* there is new data available. Several rQ* methods are available to
* read binary data off of the receive queue.
