Do all rendering to a hidden canvas and then copy over the finished
frame to the visible canvas once everything is done. This simplifies
things and solves some bugs as we can retain a copy of the entire
frame buffer.
setTimeout() is subject to delays, possible massive ones. As such it
is rather useless for performance sensitive code. Use the non-standard
setImmediate() API instead, emulating it on postMessage() when it
isn't available.
The hacks needed to run these tests require proper handling of
properties. Unfortunately IE and old versions of Chrome mess up,
so just skip the tests there.
We have to temporarily replace window.navigator due to the fact that
its property languages is read-only. The tests for the translation
utilities require different values of this property. The failing tests
were added in merge of PR #718 (in commit
f5bf2d84ef).
RFB's _fail function logs the error, disconnects the session and sets
disconnect_reason. The disconnect_reason is upon disconnection sent to
the user interface. It is thus not suitable for including error details
that aren't user friendly. The idea is that you will look in the
browser console for a full log with details of the error.
Node.js doesn't handle characters high up in the unicode range
properly with charCodeAt(). Adding a new test for UCS-4 codepoints
using codePointAt() to cover this.
There is a specific event for when an image has finished loading,
so trigger on that rather than polling. The polling interval of
requestAnimationFrame() can also be very large.
The callers don't need to concern themselves with how images are
rendered, so hide the details behind the API. This also avoids
exposing the render queue.
The states 'loaded', 'failed' and 'fatal' were all variations of the
'disconnected' state. Removing these states allows us to get rid of
many ugly workarounds and special cases. Error messages to the UI can
now instead be delivered via a new onDisconnected callback.
Names such as 'disconnect' and 'disconnected' are inconsistent in the
way that one describes an action and the other a state. The state that
was called 'normal' didn't fit in with the others because the other
names describe a connection state. The new names are: 'disconnecting',
'connecting' and 'connected'
We already have a callback mechanism for this, so let's use that.
Adds an optional parameter 'msg' to the callback.
Fixes vnc_auto.html (#646) which was broken after

The RFB protocol specifies a max version of 3.8, but RealVNC likes to
increment their version when they add new features. RealVNC 5.3 sends
"005.000" as the version string, since they've extended their
implementation upon RFB v3.8. We can detect that, and just tell them we
only speak 3.8, instead of barfing on "005.000" as an invalid version.
This commit moves all the input-related files from `core/`
to `core/input/`, and renames a couple as relevant
(input.js --> input/devices.js, keyboard.js --> input/util.js).
The event-related wrapper functions in Util existed mainly for
backwards-compat. However, all currently supported browsers
support the standard functions, so these wrappers are no longer needed.
This commits prevents Util from modifying the window object.
- `window.requestAnimFrame` was removed (no polyfill is needed anymore)
- the potential redefinition of `console.log` and friends was removed
(all supported browsers have `console.xyz` defined anyway)
This commit switches over to use PhantomJS 2.x, bringing in a whole host
of improvements (including `Function#bind`, so we can remove the
`Function#bind` shim in core/util.js).
This commit removes our modification of the Array prototype.
It wasn't actually used much in the main code, anyway, and it's a
bad practice to modify built-in prototypes.
This commit restructures noVNC, splitting it into the core directory
and the app directory, with the former containing core noVNC parts,
and the latter containing parts specific to the application.
In input.js, a new keyboard handler was added to deal exclusively
with the QEMU key event extension. '_onKeyPress()' signature
was changed to allow the same method to treat both cases.
The extension will only be enabled if the browser has support
for the KeyboardEvent.code property.
Changes in rfb.js:
- added a new extension code, QEMUExtendedKeyEvent, value -258.
- handleKeyPress now receives 'keyevent' instead of 'keysym' and
'down'. Both values are retrieved from keyevent as they were
in the previous signature. This method now can send QEMU RFB
extended key messages if the flag was set to 'true'.
- tests/test.rfb.js were changed folowing the onKeyPress() signature
change.
- added a new function to send the QEMU extended key message.

This new file contains the XT scancode mapping that
the extension will use in rfb.js file.

Instead of requesting frame buffer updates we can, if the server
supports it, continuously recieve frame buffer updates at a rate
determined by the server.
The server can use fencing messages and measure response times to
determine how often it will continue to send updates.
