Joel Martin a8edf9d8a5 Query string cleanup and move it to util.js 2010-07-22 11:33:21 -05:00
Joel Martin a7a8962676 JSLint. RFB obj to rfb.js; vnc.js the 'loader'.
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.

Joel Martin 19463eac1f Fix logging init on first page load (not in cookie). 2010-07-22 10:46:50 -05:00
Joel Martin f7f69d8eaa Fix error when cursor Data URI scheme not supported. 2010-07-22 10:26:50 -05:00
Joel Martin da6dd8932e API changes. Client cursor and settings menu.
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.

Joel Martin f55b6b4185 Fail if initial server connection fails. 2010-07-20 14:54:49 -05:00
Joel Martin 2c2b492c0c Add Cursor pseudo-encoding support (disabled for now).
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).

Joel Martin f00b1e3776 State machine refactoring.
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.

Joel Martin 754e0c0bee UTF-8: send 0 as 256 during encoding too.
0 is valid UTF-8, but in order to avoid WebSockets framing, we
encode/decode it as 256.

Also, be tolerant of 0 length messages.
2010-07-14 16:57:02 -05:00
Joel Martin 77c7a454ac TightPng fixups and thanks to Sentry Data Systems.
- Change tightpng encoding number to -260 (aliguori provided it until
  an official number can be allocated).
2010-07-13 17:51:26 -05:00
Joel Martin 447cd4ade3 Remove unneeded mootools and FABridge test.
mootools is no longer needed. The bug that the FABridge test was
testing has been resolved in web-socket-js so it's no longer needed.
2010-07-06 12:14:38 -05:00
Joel Martin 81e5adafef Refactor console logging code.
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

Joel Martin ae0ecca2e4 Disable excanvas experiment.
Also, move bugs from TODO to github issues.

Joel Martin 2ca053affc Rebuild web-socket-js swf with gimite updates.
Bug fixes, restore RFC2817 proxy for non wss://, and handle new closing
handshake from WebSockets 76.
2010-07-02 10:50:52 -05:00
Joel Martin 1144eaa37a Add global variable option for swf location.
The problem is, you can't set WebSocket.__swfLocation before you load
web_socket.js (because it creates the WebSocket global), but you also
can't reliably set WebSocket.__swfLocation after because if you are
doing dynamic script file includes then the onload (i.e.
WebSocket.__initialize) may fire before you have a chance to set
Websocket.__swfLocation.

Joel Martin b9633f8bfd Import/merge gimite/web-socket-js up to da7caff96496c7d7bfb3.

Joel Martin 2b71a4db58 Update web-socket-js binary build and README.md
Brings it up to date with the most recent web-socket-js event handling
fixes.
2010-07-01 12:04:26 -05:00
Joel Martin bc8e3d4db7 Opera fixes and big Opera performance boost.
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.
2010-07-01 11:54:44 -05:00
Joel Martin 4a96178307 Better web-socket-js dataQueue reset.
At connect and close time instead of initialization time.
2010-07-01 10:35:03 -05:00
Joel Martin 9479c72083 web-socket-js event fixes.
When using web-socket-js, the onopen event may happen inline so the
caller may not have time to set onopen before the event fires. In this
case set a short timeout and try again. In particular this affects
Opera most of the time.

Also, to get around Opera event droppings, always read the readyState
directly instead of relying on the local readyState variable to be
correct (which it isn't if stateChange event were dropped).

Joel Martin 6713418413 Always prefer JS ops if we have imageData.
All browsers with Canvas imageData are faster with JS ops instead of
canvas ops. This gives significant performance improvement in Opera.
Except for missing web-socet-js message notifications, Opera 10.60 is
now faster than firefox 3.5.
2010-07-01 10:30:07 -05:00
Joel Martin a93c955538 Opera works! Fix message event drops/reorders.
Instead of relying on FABridge AS -> JS event delivery, we just use
the events to notify JS of pending data. The message handler then
calls the AS readSocketData routine which sends back an array of
the pending WebSocket frames.

There is still a minor bug somewhere that happens after the first
connect where the web-socket-js throws an "INVALID_STATE_ERR: Web
Socket connection has not been established". But, Opera is now usable
and we should be able to drop the packet sequence numbering and
re-ordering code.

Another minor issue to better support Opera is to move JS script
includes to the <head> of the page instead of after the body.

Joel Martin 5235b29ddf Significant firefox perf improvement. Update TODOs.
Interesting. Enough has changed in the Canvas tile operations, that
Canvas.prefer_js=true is better for firefox/gecko too. Approximately
2X improvement in firefox for large hextile renders.
2010-06-29 14:36:18 -05:00
Joel Martin dfa8db8f38 Fix issue #7: security scheme list parsing.
Also, lower connect timeout to 2 seconds.

Joel Martin 48eed1ac05 Refactor canvas imageData test slightly. 2010-06-24 17:09:54 -05:00
Joel Martin 486cd527f2 Support WebSockets 76 (hixie-76, hybi-00).
Looks like disabling web-socket-js debug messages by default that we
get a minor speedup.

Python proxy should support both 75 and 76 (00) modes. Also, update ws
test to more reliably hit the WebSockets ordering/drop issue.

Joel Martin d93d3e09ab Various cross-browser fixes.
Now working under Arora 0.5.

Joel Martin 63708ff5a8 Add CtrlAltDel send button to status bar.
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.

Joel Martin 15046f0042 No mootools dep outside of default_controls.js.
