  1. Fix CSS sizes with HTML5 doctype.

    Using HTML5 doctype means CSS pixels sizes must have "px" suffix which
    many of them did not. Fix that.

  2. IE9 fixes. Works but slow. API change.

    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: 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).

  1. Opera 11 WebSockets and Opera '-' key mapping fix.

    Opera 11 native WebSockets (if enabled) seems to have bad behavior for
    the bufferedAmount so add change from websockify project to allow max
    bufferedAmount (before send queue is delay) to be configured.
    Also, Opera 11 and 10.60 behave like Mozilla regarding the '-' key so
    translate it correctly.

  2. websock.send returns true/false.

    If all send data was flushed from the send queue then return true,
    otherwise false. This doesn't mean the data won't be sent, just that
    it wasn't sent this time and is queued.
    kanaka committed Jan 24, 2011
  3. Tolerate some bufferedAmount.

    Only delay sending data if bufferedAmount is greater than 1000.
    This seems to match the intention of the spec better. bufferedAmount
    does not mean that we can't send, it's just an indication that the
    network is becoming saturated. But Opera 11 native WebSockets seems to
    have a bug that bufferedAmount isn't set back to zero correctly so
    we'll be a bit more tolerant.

  1. web-socket-js: Add function invocation fix.

    Related to this issue:
    This prevents the "Uncaught exception: TypeError:
    'this.__handleEvents' is not a function" everytime the timer fires.
    Yay, one of Javascript's worst behaviors; the way it sets "this".

  2. include/canvas.js: fix changeCursor data format.

    Issues #27 (safari cursor rendering messed up) and #29 (firefox 3.6.10
    Finally found some better reference on the icon/cursor format which is
    added to the docs/links file.
    It seems like I was missing the XOR section. So setting the cursor
    would cause corruptin in Safari rendering or the segfault for firefox.

  1. Convert to Websock library.

  1. wstelnet: forgot VT100.js.

    kanaka committed Jan 12, 2011
  2. wsproxy, wstelnet: wrap command, WS telnet client.

        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,, 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 ( must be built first):
            ./utils/ --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.
        To demonstrate the wrap command mode, I added WebSockets telnet
        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/ --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 which handles the
        terminal emulation and rendering.
        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 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=./ 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
    - Move getKeysym routine out of Canvas object so that it can be called

  1. wswrapper: add dup2, fix select w/ NULL timeout.

    - add dup2 functionality. This requires adding a ref cnt to the
      _WS_connections structure so that we only free the structure once
      all dup'd referenced are closed. Also, refactor malloc and free of
      connection structure into _WS_alloc and _WS_free.
    - allow select to accept a NULL timeout value which means sleep
      forever instead of segfaulting.
    - fix some compile warnings related to ppoll definition.
    - move some WebSockets related html test pages into utils and symlink
      them from tests.

  1. Refactor and cleanup and deps.

    Moved code into a class WebSocketServer. WebSockets
    server implementations will sub-class and define a handler() method
    which is passed the client socket after. Global variable settings have been
    changed to be parameters for WebSocketServer when created.
    Subclass implementations still have to handle queueing and sending but
    the parent class handles everything else (daemonizing, websocket
    handshake, encode/decode, etc). It would be better if the parent class
    could handle queueing and sending. This adds some buffering and
    polling complexity to the parent class but it would be better to do so
    at some point. However, the result is still much cleaner as can be
    seen in
    Refactored and (formerly to use the new
    class. Added as a simple echo server.
    - rename tests/ to utils/ and add a symlink from
    - rename tests/ws.html to tests/wstest.html to match utils/
    - add utils/
    - add tests/wsecho.html which communicates with and simply
      sends periodic messages and shows what is received.
