[Laszlo-dev] [UPDATED^3] For Review: Change 20080313-ptw-5 Summary: LZX classes as JS2 classes

[P T Withington]

[UPDATED: Ok, with this update, the smokecheck passes and Amazon seems  
to work for me.  I'd like to check this in so Henry/Don can work on  
porting it to devildog while Max/I continue debugging in trunk.]

Summary: LZX classes as JS2 classes

New Features: The tag compiler now emits LZX classes as JS2 class  
declarations

Bugs Fixed:
LPP-1587 'ECMA4: Compile LZX declarations as JS declarations' (partial)

Release Notes:
     Classes defined using the <class name="name"> _must_ be referenced
     in script as `lz.name`, there will no longer be a global alias
     `name` that refers to the class implementing the tag.

     getAttribute is deprecated.  You should just reference the
     attribute directly.  getters are no longer supported.

Details:
     Highlights:  The tag compiler now emits user classes as a JS2
     class declaration.  UserClass.lzs is dead.  Setters are now just
     methods on a class with a distinctive name, so the whole setters
     table inheritance mechanism is gone.  Early/delayed setters is a
     private protocol between LzNode and LzView.  All classes have a
     uniform 'namespace' naming scheme: $lzc$class_<tagname>, old LFC
     class names are maintained for compatibility, but there are NO
     global class names any more.  All user code will have to be
     updated to use lz.<tagname> to address classes for `new` or
     `instanceof` tests.

     Every LFC Class: Use new static `attributes` mechanism, new
     setters methods naming scheme, remove old setters table.

     LzNode: Implement new static `attributes` mechanism.  Break out
     mergeAttributes and mergeChildren as class methods so they can be
     used by user classes.  Fetch default attributes from constructor.
     Install decls compiler can't detect.  Merge with instantiation
     attributes.  Use common merge subroutines.  Install namespace
     alias.  Remove all obsolete inherited hashes now that we use class
     inheritance to manage that.  Early/delayed setters are now a
     private protocol between Node and View.  No other classes should
     use these.  In applyArgs look for setters as methods.  Deprecate
     getAttribute, getters have not been supported for a long time.
     Update setAttribute to use setter methods.  Remove old setters
     mechanism.  Deprecate __LZaddSetter, __LZstoreRefs -- private
     protocol no longer supported.  Change options setters to create
     necessary inherited hash on the fly.

     UserClass: Empty, save for documentation and the placement kludge.

     LzDefs: Flatten inherited hash so we can dispense with
     _ignoreAttribute (and be portable!).

     LzView, LzCanvas: Cooperate with LzNode on early/late setters.

     LzState: Adapt to new user class implementation which may place
     state methods in the wrong place, and won't allow dynamically
     adding setters.

     TODO: Clean up the setter trampolines to be the actual setters
     and have the old public setXXX methods call them (with a
     deprecation warning where appropriate).

     Schema: intern types.

     JavascriptGenerator: Don't make checked nodes outside of a
     function context (you won't have a 'this').

     JavascriptGenerator, CodeGenerator: Temporarily turn of
     setAttribute inlining until it can be updated.

     CommonGenerator: Translate declared attributes as having an  
undefined
     initial value.

     ScriptCompiler: Support for converting objects to script,
     including undefined values.

     ScriptClass: Complete implementation that writes out a class as a
     JS2 class declaration.

     ClassCompiler: Compile user classes to JS2 class declarations,
     which mostly involves mimicing the way UserClass used to
     initialize according to the various types of initial values,
     setters, and stateliness that you might have.

     CanvasCompiler, CompilationEnvironment, etc.: Eliminate vestigial
     support for case-insensitive runtimes

     NodeModel: Support class compilation by delaying conversion of
     bindings for attributes.

     ClassModel:  Support for (not yet used) merging of superclass
     attributes and setters.  Missing modelling of built-in classes.

Tests:
     smokecheck (minus broken test LPP-5610) passes in both runtimes,
     amazon runs in both runtimes
