API change: for intergrators that explicitly include the Javascript
files (that do not use include/vnc.js)js, include/input.js is a new
file that must also be included.
The mouse and keyboard handling could be useful on its own so split it
out into a Keyboard and Mouse class in include/input.js.
This refactoring is preparation to deal with issue #21 - non-US
keyboard layouts.
Current timeout is 2 seconds for connect timeout. Use 5 seconds if
web-socket-js (Flash WebSockets emulator) is being used. On Windows XP
with Flash 10.2.152.26, connecting seems to take quite a bit longer
than it probably should. This should make it work more consistently.
Thanks to Michael Sersen for creating images/Logo.svg.
- Add images directory with original SVG logo, favicon, and some
derivative PNGs of the logo for different purpose.
- Note that license on images/* is CC BY-SA.
- Add utils/img2js.py to take an image and generate a base64 encoded
data URI string.
- Add base64 encoded data URI screen logo to display in canvas when
disconnected.
API change: changed include path variable from VNC_uri_prefix to
URI_INCLUDE since websock.js uses the variable and websock.js is no
longer just for noVNC (i.e. websockify is really the canonical
location for websock.js).
Changes to get web-socket-js to work. Right now it's a hack to get
around: https://github.com/gimite/web-socket-js/issues#issue/41. The
hack is to disable caching of the flash objects by appending
"?" + Math.random() to the end of the flash object path (but only when
using IE).
- util.js that contains essential functions
- webutils.js that contains the GUI utility function.js
this helps to include noVNC in other project, especially Cappuccino Application
i
web-socket-js now has all the functionality and fixes needed for noVNC
so remove the include/as3crypto_patched directory and the
include/web-socket-js/flash-src directory (i.e. the sources for
web-socket-js). This cleans up almost 3K from the include/ directory.
Update to web-socket-js build based on upstream (gimite/web-socket-js)
9e766377188.
Move the whole RFB object to rfb.js. vnc.js is now just the loader
file. This allows an integrating project to easily replace vnc.js with
an alternate loader mechanism (or just do it directly in the html
file). Thanks for the idea primalmotion (http://github.com/primalmotion).
Also, JSLint the various files.
The following API changes may affect integrators:
- Settings have been moved out of the RFB.connect() call. Each
setting now has it's own setter function: setEncrypt, setBase64,
setTrueColor, setCursor.
- Encrypt and cursor settings now default to on.
- CSS changes:
- VNC_status_bar for input buttons switched to a element class.
- VNC_buttons split into VNC_buttons_right and
VNC_buttons_left
- New id styles for VNC_settings_menu and VNC_setting
Note: the encrypt, true_color and cursor, logging setting can all be
set on load using query string variables (in addition to host, port
and password).
Client cursor (cursor pseudo-encoding) support has been polished and
activated.
The RFB settings are now presented as radio button list items in
a drop-down "Settings" menu when using the default controls.
Also, in the settings menu is the ability to select between alternate
style-sheets.
Cookie and stylesheet selection support added to util.js.
To change the appearance of the cursor, we use the CSS cursor style
and set the url to a data URI scheme. The image data sent via the
cursor pseudo-encoding has to be encoded to a CUR format file before
being used in the data URI.
During Canvas initialization we try and set a simple cursor to see if
the browser has support. Opera is missing support for data URI scheme
in cursor URLs.
Disabled for now until we have a better way of specifying settings
overall (too many settings for control bar now).
Add new states 'loaded', 'connect' and 'fatal':
- Loaded state is first page state. Pass WebSockets mode message using
this state.
- Connect indicates that the user has issued a "connect" but we
haven't gotten an WebSockets onopen yet.
- Fatal is a condition that indicates inability to continue on: right
now, lack of WebSockets/Flash or non-working canvas.
Move much of the actual state transition code into updateState.
Handle 'password' state better in default_controls.js; instead of
disconnecting, prompt for password to send.
Add comments to updateState indicating possible states.
Util.Debug, Util.Info, Util.Warn, Util.Error routines instead of
direct calls to console.*. Add "logging=XXX" query variable that sets
the logging level (default is "warn").
Logging values:
debug: code debug logging (many calls in performance path are also
commented for performance reasons).
info: informative messages including timing information.
warn: significant events
error: something has gone wrong
Add message/state pollling in web-socket-js. Since Opera tends to drop
message events, we can dramatically increase performance by polling
every now for message event data.
Also, add more direct calls to update readyState so that it's not
missed when Opera drops events.
Some default_controls.js jslinting.
Needs to be some modularity between controls you probably always want
(like sending CtrlAltDel) and how the interface is presented and
controlled.
Some basic functions from mootools implemented in util.js.
Also, some more DOM separation. Move clipboard focus logic into
default_controls and canvas and out of vnc.js.
JSLint cleanup.
