The MPL 2.0 license is a "file-level" copyleft license vs the
"project-level" nature of the L/GPL. The intention of the websock.js
file has always been that it should be easy to incorporate into
existing projects and sites whether free/open or
proprietary/commercial. The MPL 2.0 is designed for this sort of
combination project but still requires that any distributed
modifications to noVNC source files must also be published under the
same license.
In addition, the MPL 2.0 allows the code to be used in L/GPL projects
(the secondary license clause). This means that any projects that are
already incorporating noVNC should not be impacted by this change and
in fact it should clarify the licensing situation (the exact
application of the L/GPL to web applications and interpreted code is
somewhat ambiguous).
The dependencies on include/websock.js are also updated to MPL 2.0
including util.js and webutil.js. The base64.js has been updated to
the MPL 2.0 licensed version from Mozilla.
The websockify python code (and other implementations) remain under
a LGPLv3 license.
Rename the $() selector to $D() so that it doesn't collide with
the jQuery name.
The API change is that the 'target' option for Canvas and RFB objects
must now be a DOM Canvas element. A string is no longer accepted
because this requires that a DOM lookup is done and the Canvas and RFB
should have no UI code in them. Modularity.
- 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
