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).

wswrapper: Getting the wswrapper.c LD_PRELOAD model working has turned out to involve too many dark corners of the glibc/POSIX file descriptor space. I realized that 95% of what I want can be accomplished by adding a "wrap command" mode to wsproxy. The code is still there for now, but consider it experimental at best. Minor fix to dup2 and add dup and dup3 logging. wsproxy Wrap Command: In wsproxy wrap command mode, a command line is specified instead of a target address and port. wsproxy then uses a much simpler LD_PRELOAD library, rebind.so, to move intercept any bind() system calls made by the program. If the bind() call is for the wsproxy listen port number then the real bind() system call is issued for an alternate (free high) port on loopback/localhost. wsproxy then forwards from the listen address/port to the moved port. The --wrap-mode argument takes three options that determine the behavior of wsproxy when the wrapped command returns an exit code (exit or daemonizing): ignore, exit, respawn. For example, this runs vncserver on turns port 5901 into a WebSockets port (rebind.so must be built first): ./utils/wsproxy.py --wrap-mode=ignore 5901 -- vncserver :1 The vncserver command backgrounds itself so the wrap mode is set to "ignore" so that wsproxy keeps running even after it receives an exit code from vncserver. wstelnet: To demonstrate the wrap command mode, I added WebSockets telnet client. For example, this runs telnetd (krb5-telnetd) on turns port 2023 into a WebSockets port (using "respawn" mode since telnetd exits after each connection closes): sudo ./utils/wsproxy.py --wrap-mode=respawn 2023 -- telnetd -debug 2023 Then the utils/wstelnet.html page can be used to connect to the telnetd server on port 2023. The telnet client includes VT100.js (from http://code.google.com/p/sshconsole) which handles the terminal emulation and rendering. rebind: The rebind LD_PRELOAD library is used by wsproxy in wrap command mode to intercept bind() system calls and move the port to a different port on loopback/localhost. The rebind.so library can be built by running make in the utils directory. The rebind library can be used separately from wsproxy by setting the REBIND_OLD_PORT and REBIND_NEW_PORT environment variables prior to executing a command. For example: export export REBIND_PORT_OLD="23" export export REBIND_PORT_NEW="65023" LD_PRELOAD=./rebind.so telnetd -debug 23 Alternately, the rebind script does the same thing: rebind 23 65023 telnetd -debug 23 Other changes/notes: - wsproxy no longer daemonizes by default. Remove -f/--foreground option and add -D/--deamon option. - When wsproxy is used to wrap a command in "respawn" mode, the command will not be respawn more often than 3 times within 10 seconds. - Move getKeysym routine out of Canvas object so that it can be called directly.

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.

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 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.

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.

Pull in LGPL md5.c and md5.h files (written by Ulrich Drepper). Now both python and C version of the proxy support both protocol 75 and protocol 76 (hybi 00). Reorganize websocket.py slightly to match websocket.c.

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.

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.

The purpose of the code is to be incorporated into other web projects (whether those are free or not). AGPL prevents combination with other HTML and javascript that is under a weaker (or proprietary) license. Better would be a lesser AGPL, but there is not GNU standard for that. So LGPL-3 meets most of my requirements. If somebody modifies the actual client code and conveys it, then they must release the changes under LGPL-3 also. Add some implementation notes in docs/notes.

wss://'Joel Martin authored
On the client side, this adds the as3crypto library to web-socket-js so that the WebSocket 'wss://' scheme is supported which is WebSocket over SSL/TLS. Couple of downsides to the fall-back method: - This balloons the size of the web-socket-js object from about 12K to 172K. - Getting it working required disabling RFC2718 web proxy support in web-socket-js. - It makes the web-socket-js fallback even slower with the encryption overhead. The server side (wsproxy.py) uses python SSL support. The proxy automatically detects the type of incoming connection whether flash policy request, SSL/TLS handshake ('wss://') or plain socket ('ws://'). Also added a check-box to the web page to enable/disabled 'wss://' encryption.

- All state/status updates go through updateState routine which updates the status line also. - Old firefox (and opera) don't support canvas createImageData, so use getImageData as replacement. - Add console.warn and console.error stubs so that firefox without firebug doesn't crap out. - If no WebSockets then error if no flash or if URL is location (flash will refuse to load the object for security reasons).

- web-socket-js is from http://github.com/gimite/web-socket-js. It is a flash object that emultates WebSockets. Unfortunately, events (or packets) from the web-socket-js object can get re-ordered so we need to know the packet order. - So wsproxy.py prepends the sequence number of the packet when sending. - If the client receives packets out of order it queues them up and scans the queue for the sequence number it's looking for until things are back on track. Gross, but hey: It works! - Also, add packet sequence checking to wstest.*
