The decrypt functionality is never used so remove it. Also, we can assume that we are always DES encrypting 16 characters which allows several things to be simplified in DES. Overall this removes about 80 lines of code.

- include/util.js: Add type and desc field to conf_default routine. Make comment descriptions of settings into desc parameters that can be queried. Also, use set_FOO in conf_default to set or coerce the current setting so that we always have the right type for the value. - include/rfb.js, include/default_config.js: add connectTimeout setting to address situations with slow connections that may need more than 2 seconds.

Yet another weird VNC server behavior: sending a failure and length before the reason message. To calculated the length, the reason string is already available, why not just send everything as one packet. Oh well.

In Safari, local cursor rendering is corrupt. In firefox 3.6.10, local cursor rendering causes a segfault. Probable that the .cur format is not 100% compliant (even though it works in Chrome and firefox 3.5 and firefox 4.0). So just disable it by default until I can figure out how to address the problems.

Add a new state 'disconnect' to reflect that we are not truly 'disconnected' until we get an onclose event. Add a disconnect timer to match. Handle disconnected cleanup better in updateState(). Anytime we enter in a disconnect/disconnected state, make sure all running state is cleaned up (WebSocket, timers, canvas).

Filed this issue for this bug: http://github.com/gimite/web-socket-js/issues/issue/37 Right now the close() call only calls __flash.close() if readyState is OPEN. But it should really call close any time that readyState is not CLOSED or CLOSING. The case I ran into is when I want to do the following: 1. make a test connection 2. tell the server to setup for a connection 3. connect again I call close on the test connection, but since it is ignored when CONNECTING, it eventually times out with a error. But by that time I have already issued a new connection, it causes the new connection to fail. close() should cancel CONNECTING state too.

Filed this bug about this issue: http://github.com/gimite/web-socket-js/issues#issue/35 To work around the flash "recursive call" problem, WebSocket.as has the onclose event disabled in the close() call and the javascript half of the close() call does the onclose() call instead. This is fine, but it needs to be asynchronous to act more like what happens with a normal WebSockets object. The current behavior is that the onclose() method is called inline (synchronously) when the close() is called and this inconsistency make state handling more difficult.

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.

The rfb variable wasn't available at the point settingsDisabled() was being called since it was called inline with RFB() initialization. To solve this we pass the updateState rfb variable so that the canvas can be queried for setting the cursor_uri value.

This is logical now since the external update callback can be provided when the object is created so we don't need a separate init function.

It's less efficient on average that base64 (150% vs 133%). It's non-standard (0 shifted to 256 before encoding). And I rarely use it.

Turned out not to be useful (pretty much never looked at the info once I added it). The playback test is much more useful for measuring performance.

Generally, most servers send hextile updates as single updates containing many rects. Some servers send hextile updates as many small framebuffer updates with a few rects each (such as QEMU). This latter cases revealed that shifting off the beginning of the receive queue (which happens after each hextile FBU) performs poorly. This change switches to using an indexed receive queue (instead of actually shifting off the array). When the receive queue has grown to a certain size, then it is compacted all at once. The code is not as clean, but this change results in more than 2X speedup under Chrome for the pessimal case and 10-20% in firefox.

Apparently there are versions of UltraVNC that report version 3.6. This is not a legal version according to the spec, but we'll just force version 3.3 if we receive it. Thanks to Larry Rowe for the info.

Turns out when Windows is running in QEMU and a window scroll happens, there are lots of little hextile rects sent. This is slow in noVNC. - Some recording/playback improvement. - Add test harness to drive playback of recordings. - By pulling off the rect header in one chunk we get a 3X speedup in Chrome and a 20% speedup in firefox (specifically for the scroll test). - Also, get rid of some noise from creating timers for handle_message. Check to make sure there isn't already a pending timer first.

New API: To use the RFB object, you now must instantiate it (this allows more than one instance of it on the same page). rfb = new RFB(settings); The 'settings' variable is a namespace that contains initial default settings. These can also be set and read using 'rfb.set_FOO()' and 'rfb.get_FOO()' where FOO is the setting name. The current settings are (and defaults) are: - target: the DOM Canvas element to use ('VNC_canvas'). - encrypt: whether to encrypt the connection (false) - true_color: true_color or palette (true) - b64encode: base64 encode the WebSockets data (true) - local_cursor: use local cursor rendering (true if supported) - connectTimeout: milliseconds to wait for connect (2000) - updateState: callback when RFB state changes (none) - clipboardReceive: callback when clipboard data received (none) The parameters to the updateState callback have also changed. The function spec is now updateState(rfb, state, oldstate, msg): - rfb: the RFB object that this state change is for. - state: the new state - oldstate: the previous state - msg: a message associate with the state (not always set). The clipboardReceive spec is clipboardReceive(rfb, text): - rfb: the RFB object that this text is from. - text: the clipboard text received. Changes: - The RFB and Canvas namespaces are now more proper objects. Private implementation is no longer exposed and the public API has been made explicit. Also, instantiation allows more than one VNC connection on the same page (to complete this, DefaultControls will also need this same refactoring). - Added 'none' logging level. - Removed automatic stylesheet selection workaround in util.js and move it to defaultcontrols so that it doesn't interfere with intergration. - Also, some major JSLinting. - Fix input, canvas, and cursor tests to work with new model.

If cursor Data URI scheme detection threw an exception, it would cause canvas initialization to fail. cursor detection exceptions should just disable local cursor change support, not cause canvas init to fail.

Uses the CSS "scale()" operation. The main problem is that the DOM container is not rescaled, only the size of the displayed content within it so there will need to be some sort of mechanism to handle this better so other elements reflow to the new size. Or it might just not work and be removed later. The zoom property seems to do the right behavior, but it's not widely supported. Worth exploring though.

After each complete framebufferUpdate, set a short timer to continue processing the receive queue. This gives other events a chance to fire. Especially important when noVNC is integrated into another website.

noVNC was never processing more than one framebufferUpdate message per onmessage event. If noVNC receives an incomplete framebufferUpdate and then receives the rest of the framebufferUpdate plus another complete framebufferUpdate, then it will fall permanently behind. If there is more to process after a completed framebufferUpdate, then execute normal_msg again. All the render routines must return false if there is not enough data in the receive queue to process their current update, and true otherwise.
