This commit updates the UI to allow for different
scaling modes. The "resize" option was changed to
be a dropdown with the following options: "None" (nothing),
"Remote Resizing" (SetDesktopSize).
Commit 5108c4635c caused a regression
in the case where scrolling is used -- getPosition return position
relative to the viewport, while getEventPosition expected a position
relative to the page.
As per
https://developer.mozilla.org/en-US/docs/Web/API/Element/getBoundingClientRect,
the fix for this is simply to add the `pageXOffset` and `pageYOffset` to
the output of `getBoundingClientRect()`.
Fixes#459.
Commit 155d78b399 prevented reconnections
from working properly. This fixes that by creating a new RFB object
after disconnecting or failing.
Furthermore, this ensures that a new connection cannot be opened util
we've actually disconnected (either by timer or by receiving a `close`
event).
Closes#452
* Added a resize request (setDesktopSize) triggered when connecting and by
changes to the browser window's size.
* Hid the view-drag-hand when the display area is the same or smaller than the
remote session size.
* Added a setting for the automatic resize feature.
* Updated vnc.html and vnc_auto.html to reflect the changes to the UI.
* Split viewportChange into two functions, one for changing size and the other for changing position.
* Modified viewport code to be capable of changing to a bigger size in the context of a
client-initiated resize.
* Made clearer distinctions between when viewport-clipping or not.
* Added public function for telling when viewport-clipping.
* Updated tests that were using viewportChange.
Previously, if a HEXTILE tiles was received with a subencoding
of 0x00, it would draw a rectangle using data from the render
queue, which would result in random colored blocks when using
the HEXTILE encoding. This is the result of a miscopy during
the refactoring. It now has the correct functionality according
to the RFB protocol specification, which is to draw a rectangle
with the last set background color.
Closes#411
Previously, we were modifying Array's prototype using
simple assignment. This can mess with enumeration/iteration.
Thus, we now use Object.defineProperty with enumerable set to
false.
See #366
There was a race condition in Display#clear on IE10
because we resize and then clear that causes the canvas
to not actually end up cleared. Clearing the current
viewport first solves the issue. It doesn't appear to
affect other platforms, so it's inside a engine check
(`Util.Engine.trident === 6`). Once we stop supporting
IE10, we should just remove this, because it's not the best
to have Engine-specific code.
There was a bug in cursor URI support detection due to the way
set_defaults now works -- the code was checking for `null`, whereas
when not set, options default to `undefined` unless otherwise
specified. The code now checks for either `null` or `undefined`.
Tests have been added to ensure that this works properly.
Previously, Utils.set_defaults was using `if(conf[keys[i]])`
to check for the presence of a configuration key. This would
fail if `conf[keys[i]]` happened to be false. Instead, we now
use `if(keys[i] in conf)`, which simply checks for the presence
of the key in the conf object.
There was a typo in one of the instances of the _buttonMask field
(it was written as _buttonMaks), causing MouseUp to never be sent.
This has been rectified, and the unit tests for the mouse handler
have been changed to check for explicitly sending mouseup and
mousedown.
Fixes#393
File: ui.js
Tests Added: False
Changes:
- Fix JSHint errors
- add some curly braces to improve clarity
- move variable declarations to relevant locations instead of at the top
of methods
File: display.js
Tests Added: True (preliminary)
Changes:
- De-crockford-ified the file
NOTE: the tests included for display.js cover basic functionality, but
are by no means nearly as comprehensive as the ones presented for
rfb.js.
File: websock.js
Tests Added: True
Changes:
- Cleaned up JSHint errors
- Converted to normal JS constructor pattern with "private" fields and
methods now simply being prepended by underscores
- Added a "bind" polyfill for use in PhantomJS 1.x in util.js
- Added FakeWebSocket to fill in for actual WebSocket objects when
testing
- Made exception handler actually log exception name and message,
to console, in addition to stack trace
File: webutil.js
Tests Added: False
Changes:
- Fixed JSHint Errors (global "use strict", spaces)
- added some newline characters when appropriate for readability
- moved variable declarations to the places they were actually used
for readability
File: input.js
Tests Added: False (already present partially -- see below)
Changes:
- Fixed JSHint Errors
- Converted to normal non-Crockford constructors
NOTE: while there are tests for the actual key-detecting functionality,
the tests do not cover the actual Keyboard and Mouse objects
themselves.
File: util.js
Tests Added: True (partial -- for logging and array push methods)
Changes:
- Fixed JSHint Errors (indentation, semicolons, global "use strict")
- Made browser detection methods more readable
- added some newline characters when appropriate for readability
- throw Errors not strings!
- Removed conf_defaults, and added make_properties and set_defaults
instead (see below)
The removal of conf_defaults and switch to make_properties and
set_defaults is to facilitate the switch over to normal Javascript
constructors instead of Crockford-style constructors. Now, methods
are added to the objects prototype (and thus make properties is called
outside the constructor).
This is the first commit in a series of commits
which improve the readability of some of the code
and add tests.
File: base64.js
Tests Added: True
Changes:
- Improved indentation
- Fixed JSHint errors
- Moved loop variables to be declared in the loop for better readability
(N.B. Javascript does not have block scoping, so the variables are
still technically available outside the loop -- it just makes the code
clearer to place them inside the loop, since they are only used there)
Previously, Util.getPosition didn't deal with scrolling
particularly well. This fixes that by calculating the
scroll offset when dealing with getting mouse positions.
Credit to @erikgull and @emmar for the initial version of
the fix. Credit to Brian Huismanfor the initial code.

Fix keyboard handling for IE10 (issue #352)
* Keyboard events in IE10 do not provide any useful information on the properties 'which', 'char' or 'charCode'. Instead, it seems to store the char code in the keyCode property.
Apparently Firefox on Linux changed the value of navigator.appVersion,
causing our OS detection (used to determine how to interpret different
modifier keys) to fail.
Use navigator.platform instead, which should be more stable.
http://stackoverflow.com/a/19883965/33213
Previously we identified keys in keyboard events by the 'key' property
if it was set, and 'keyCode' otherwise.
This turns out to be problematic as Firefox no longer leaves 'key'
undefined (so we fall back to using 'keyCode'), but instead sets 'key'
to 'MozPrintableKey' for all printable keys.
This meant that when (printable) keys are released, we can't match it
against the corresponding keydown event, and instead just send a keyup
event for the last keydown received.
Now, if both 'key' and 'keyCode' are set, use the concatenation of both.
Otherwise prefer 'keyCode', as that is at least unique for every key.
This should let us release the right keys on keyup events.
When shortcut modifiers (modifier keys such as CTRL, which do not participate in
composing character input) are pressed, we try to suppress the keypress
event, as browsers do not reliably generate it. This means that
subsequent key events are decoded only based on the keydown event.
Due to a type error (comparing a string to a number), shift was
mistakenly treated as a shortcut modifier, preventing text input which
relied on shift, such as _ and %, from being generated.
This allows the keyboard handler to check modifier key state much more frequently
Since some browsers never send keyup events for modifier keys, we have to
synchronize modifier state whenever we get a mouse or keyboard event
Add a node.js-based tool (utils/parse.js) to read keysymdef.h and produce a JavaScript file
mapping Unicode code points to keysyms.
Also add the generated table (include/keysymdef.js).
This patch adds support for the secure attribute on token
cookies (sent by nova-novncproxy). If the https is used
to transfer the cookie, the secure attribute is set thus
restricting server requestes to secure conections only.
This should prevent man-in-the-middle attacks.
button group instead of centered.
* On low resolution devices the padding towards the edges of the screen of
the left and right button groups are now removed.
* Since the status_bar was merged into the control-bar the actual status_bar
element became redundant and was therefor removed.
* Improved the style of the control-bar when there is an error or a warning.
* Implemented a fix so that vnc_auto.html works as intended with the improved
screen real estate patch.
