The code that used these were removed in the following commits:
* 9ff86fb718 (RFB._mouse_arr)
* bb6965f2e6 (old_requestAnimationFrame)
* 490d471c53 (Display._c_forceCanvas)
This allows using TigerVNC server with PAM authentication (e.g. agains
LDAP or other extensible authentication mechanisms)
Tested with TigerVNC server (Xvnc -SecurityTypes Plain -PlainUsers '*')
Should not break anything else, this method is tried last when all
other fail.
Tested in Firefox 74 and Chromium 80
If too much text is copied in the session, String.fromCharCode.apply()
would crash in Safari on macOS and Chrome on Linux. This commit fixes
this issue by avoiding apply() altogether. Also added test to cover this
issue.
Supports both classic cursor type and alpha cursor type. In classic
mode the server can send 'inverted' pixels for the cursor, our code
does not support this but handles these pixels as opaque black.

It is not relevant for the connection stage so it should not have
been a constructor argument to begin with. Ship with a warning for
a release before we remove it.
The cursor object is only attached to our canvas whilst connecting,
so we need to make sure we don't try to update anything when were
not connected or we'll get a crash.
These are harmless and really only for debugging. So remove them
as they tend to trick people in to thinking something is wrong.
We already print the entire server pixel format earlier anyway in
case we need the details.
It is not necessary as Websock.flush() is guaranteed to succeed and
give us some space. It also remove the call to _fail(), which was
invalid at this place as clientCutText() is not a method on RFB.
* Change copyright header
This updates the copyright header to say "The noVNC Authors". People
who previously had copyright listings are now under the AUTHORS file.
With high DPI systems we can end up with a container with a size that
is not an integer number of CSS pixels. Make sure we can handle those
cases by allowing a fractional size for the output canvas. Framebuffer
size and viewport coordinates are still restricted to integer dimensions
though.
Based on initial patch by Alexander E. Patrakov.
Always use the shorthand notation if the function is a method of an object or class `{ foo() { ... } }` or `class bar { foo() { ... } }`
unless it's a callback in which case you a fat arrow function should be used `{ cb: () => { ... } }`
Some browsers don't support custom cursors, and there are cases
where the browsers refuse to show the cursor. Handle both of these
cases by letting the browser render the cursor via a floating
canvas.
This allows us to support a local cursor at all times.
Siemens' touch panels support Tight authentication as well as NOTUNNEL,
but they fail to advertise the latter. Work around this issue by detecting
a Siemens device (through their custom tunnel types) and assume NOTUNNEL
support even if not advertised.
Pasting clipboard texts that were larger than 10240 bytes didnt work and
caused a crash in noVNC. This commit fixes the crash and adds handling
for sending large clipboard texts. Fixes issue #1065.
Tight PNG rects cannot use the basic compression variants, and PNG
cannot be used in a standard Tight rect.
This is a partial revert of 3e8b26a based on better understanding
of the encoding.
The function removeChild throws an exception when the element specified
doesn't exist. This can happen when opening the websocket throws an
exception during connect. Fixes issue #979
The API allowed strings to be passed from the RFB module to the
application using the disconnect reason. This caused problems since
the application didn't have control over translations for these
strings.
Most of the information being passed using this string was very
technical and not helpful to the end user. One exception to this was
the security result information regarding for example authentication
failures. The protocol allows the VNC server to pass a string
directly to the user in the security result.
So the disconnect reason is replaced by a boolean saying if the
disconnection was clean or not. And for the security result information
from the server, a new event has been added.
Instead of exposing all the internal connection states, the RFB module
will now only send events on connect and on disconnect. This makes it
simpler for the application and gets rid of the double events that were
being sent on disconnect (previously updatestate and disconnect).
An RFB object represents a single connection so it doesn't make
sense to have one without it trying to connect right away. Matches
the behaviour of other APIs, e.g. WebSocket.
Use normal properties with JavaScript setters and getters instead of
our homegrown stuff.
This also changes the properties to follow normal naming conventions.
Sort things by category, and organise everything in the same place.
We don't support reuse of RFB objects so we can safely init everything
in the constructor.
