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.
Closes#295
Relevant to #258
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
