68e4897586 Remove Function.prototype.toMethod 
Function.prototype.toMethod was removed from ES6.

This removes the function and updates the tests to either
use %ToMethod or a dedicated syntax (using concise method
or a class).

a18b797fd9 Enable compiling mjsunit tests as ES6 modules 
Adding the line "// MODULE" to an mjsunit file will now cause
run-tests.py to prefix the test case with "--module" in the
d8 commandline.

d8 has itself been updated to treat files preceded with "--module" as
modules (that is, it compiles them with ScriptCompiler::CompileModule,
and turns on --harmony-modules).

64abe65210 Allow eval and arguments as property names 
We incorrectly disallowed eval and arguments in accessor and method
names. This was because we checked the name inside the
ParseFunctionLiteral. We now flag accessors so that lazy parsing of
these functions are treated correctly.

aeb3a71740 Begin modernization of --harmony-modules 
The approach taken in this CL is to incrementally move toward the
currently-specced version of modules in ES6. The biggest change in this
patch is separating the parsing of modules from the parsing of scripts,
getting rid of the 'module' keyword and thus disallowing modules-in-scripts
as well as modules-in-modules.

The syntax supported by import/export declarations has not yet been significantly
changed, with the major exception being that import declarations require a string
as the 'from' part.

Most of the existing tests have been disabled, with a first new test added
in cctest/test-parsing.

6ac4de87a8 harmony-scoping: make assignment to 'const' a late error. 
Per TC39 Nov 2014 decision.

This patch also changes behavior for "legacy const": assignments to sloppy const in strict mode is now also a type error. This fixes v8:2243 and also brings us in compliance with other engines re assignment to function names (see updated webkit test), but might have bigger implications.
That change can easily be reverted by changing Variable::IsSignallingAssignmentToConst.

fakes it if neededi - i.e. if ScriptContext for a script has not been

aa6815c79a Classes: Add support for arguments in default constructor 
This is currently done by generating a default constructor that looks
like this:

  constructor() {
    %DefaultConstructorSuperCall();
  }

The a runtime function implements the logic which is pretty similar to
Runtime_Apply except that it uses the [[Prototype]] of the current
function.

This is the second try. The first failed because the test was using a
array that was too large for Function.prototype.apply.

Currently, the behaviour is essentially the same as ES262's version, however this changes when internal structures
such as Promise make use of symbolToStringTag (as they are supposed to, see v8:3241), and changes further once
Symbol.toStringTag is exposed publicly.

71fbe7d4ec Ensure that JSProxy::Fix gives the generated JSObject map a constructor 
All JSObjects in V8 either have a map()->constructor() field or are
JSFunctions. JSProxy::Fix, however, was not enforcing this, and
Object.observe's use of JSObject::GetCreationContext() exposed this.

Note that this is not Object.observe-specific: the API call
v8::Object::CreationContext() also would have revealed this bug.

This patch chooses Object as a reasonable constructor to put on the
newly-fixed object's map. Note that this has no effect on the "constructor"
property in JS. In doing so, I've also tightened up the code underlying
JSProxy::Fix to only support JSObject and JSFunction as possible output
types.

ab3afc5722 Reland "Prevent liveedit on or under generators with open activations" 
The change relative to the previous CL is a logic change in
DropActivationsInActiveThreadImpl.  The previous CL skipped the matcher
unless the frame was a JS frame; this was correct for
MultipleFunctionTarget but not for SingleFrameTarget.

I have not been able to reproduce the original failures on either
architecture (ia32 or x64; stack frame dropping is unsupported on other
architectures).

70c3a714a1 ES6 Map/Set iterators/forEach improvements 
This changes how Map/Set interacts with its iterators. When the
underlying table is rehashed or cleared, we create a new table (like
before) but we add a reference from the old table to the new table. We
also add an array describing how to transition the iterator from the
old table to the new table.

When Next is called on the iterator it checks if there is a newer table
that it should transition to. If there is, it updates the index based
on the previously recorded changes and finally changes itself to point
at the new table.

With these changes Map/Set no longer keeps the iterators alive. Also,
as before, the iterators keep the underlying table(s) alive but not the
actual Map/Set.

3308cb5857 ES6: Add support for Map/Set forEach 
This implements MapIterator and SetIterator which matches
the same constructs in the ES6 spec. However, these 2
iterators are not exposed to user code yet. They are only
used internally to implement Map.prototype.forEach and
Set.prototype.forEach.

Each iterator has a reference to the OrderedHashTable where
it directly accesses the hash table's entries.

The OrderedHashTable has a reference to the newest iterator
and each iterator has a reference to the next and previous
iterator, effectively creating a double linked list.

When the OrderedHashTable is mutated (or replaced) all the
iterators are updated.

When the iterator iterates passed the end of the data table
it closes itself. Closed iterators no longer have a
reference to the OrderedHashTable and they are removed from
the double linked list. In the case of Map/Set forEach, we
manually call Close on the iterator in case an exception was
thrown so that the iterator never reached the end.

At this point the OrderedHashTable keeps all the non finished
iterators alive but since the only thing we currently expose
is forEach there are no unfinished iterators outside a forEach
call. Once we expose the iterators to user code we will need
to make the references from the OrderedHashTable to the
iterators weak and have some mechanism to close an iterator
when it is garbage collected.

0d34254f8d Upgrade Symbol implementation to match current ES6 behavior. 
Refresh the implementation of Symbols to catch up with what the
specification now mandates:

* The global Symbol() function manufactures new Symbol values,
  optionally with a string description attached.

* Invoking Symbol() as a constructor will now throw.

* ToString() over Symbol values still throws, and
  Object.prototype.toString() stringifies like before.

* A Symbol value is wrapped in a Symbol object either implicitly if
  it is the receiver, or explicitly done via Object(symbolValue) or
  (new Object(symbolValue).)

* The Symbol.prototype.toString() method no longer throws on Symbol
  wrapper objects (nor Symbol values.) Ditto for Symbol.prototype.valueOf().

* Symbol.prototype.toString() stringifies as "Symbol("<description>"),
  valueOf() returns the wrapper's Symbol value.

* ToPrimitive() over Symbol wrapper objects now throws.

Overall, this provides a stricter separation between Symbol values and
wrapper objects than before, and the explicit fetching out of the
description (nee name) via the "name" property is no longer supported
(by the spec nor the implementation.)

Adjusted existing Symbol test files to fit current, adding some extra
tests for new/changed behavior.

6b5a4cdef2 V8 Microtask Queue & API 
This patch generalizes Object.observe callbacks and promise resolution into a FIFO queue called a "microtask queue".

It also exposes new V8 API which exposes the microtask queue to the embedder. In particular, it allows the embedder to

-schedule a microtask (EnqueueExternalMicrotask)
-run the microtask queue (RunMicrotasks)
-control whether the microtask queue is run automatically within V8 when the last script exits (SetAutorunMicrotasks).

7317b71f02 Make Function.length and Function.name configurable properties. 
ES6 makes the Function object properties "length" and "name"
configurable; switch the implementation over to follow that.

Doing so exposed a problem in the handling of non-writable, but
configurable properties backed by foreign callback accessors
internally. As an optimization, if such an accessor property is
re-defined with a new value, its setter was passed the new value
directly, keeping the property as an accessor property. However, this
is not correct should the property be non-writable, as its setter will
then simply ignore the updated value. Adjust the enabling logic for
this optimization accordingly, along with adding a test.

4d338985b9 Closed generator returns a completed object instead of throwing a error 
From ES6 rev20 draft, closed generator returns completed object (the
value is `undefined` and done is `true`).
Since a error thrown in generator is propagated to the caller without
setting status of a thrown generator to "completed", once a generator is
suspended by a error, status becomes "executing" forever. This is filed
as v8:3096

e943623b12 Harmony promises 
Based on prototype at

  https://github.com/rossberg-chromium/js-promise

which informed the latest spec draft version at

  https://github.com/domenic/promises-unwrapping/blob/master/README.md

Activated by --harmony-promises.

Feature complete with respect to the draft spec, plus the addition of .when and .deferred methods. Final naming and other possible deviations from the current draft will hopefully be resolved soon after the next TC39 meeting.

This CL also generalises the Object.observe delivery loop into a simplistic microtask loop. Currently, all observer events are delivered before invoking any promise handler in a single fixpoint iteration. It's not clear yet what the final semantics is supposed to be (should there be a global event ordering?), but it will probably require a more thorough event loop abstraction inside V8 once we get there.

cec8383cff Provide private symbols through internal APIs 
Adds a notion of private symbols, mainly intended for internal use, especially, self-hosting of built-in types that would otherwise require new C++ classes.

On the JS side (i.e., in built-ins), private properties can be created and accessed through a set of macros:

  NEW_PRIVATE(print_name)
  HAS_PRIVATE(obj, sym)
  GET_PRIVATE(obj, sym)
  SET_PRIVATE(obj, sym, val)
  DELETE_PRIVATE(obj, sym)

In the V8 API, they are accessible via a new class Private, and respective HasPrivate/Get/Private/SetPrivate/DeletePrivate methods on calss Object.

These APIs are designed and restricted such that their implementation can later be replaced by whatever ES7+ will officially provide.

92bd4d1f2d I found this working on 
https://codereview.chromium.org/19541010/

The main problem is that if you called Object.getNotifier(obj) on an object, %SetObserved(object) would never get called on it, and thus it would be unobservable (new test added for this).

Additionally, Runtime::SetObserved was asserting obj->IsJSObject() which would fail if called on a proxy.

It just happens that our existing test always called getNotifier() before Object.observe on proxies, and thus we never previously attempted to transition the map of a proxy.

Both issues are now fixed and properly tested.

Both Blink and Firefox are permissive with arguments to .set method.
However, when first argument to "set" is a number, all implementations
throw, so that users know that
   a.set(0,27)
does not assign 27 to 0th element of a, not 0 to 27th element of a.

e24cc32011 GeneratorFunction() makes generator instances 
The current specification has GeneratorFunction() be like Function(),
except that it makes generator instances.  This commit implements that
behavior.  It also fills in a piece of the implementation where
otherwise calling GeneratorFunction or GeneratorFunctionPrototype would
cause an abort because they have no code.

8f602260d3 Implement yield* (delegating yield) 
Ideally this would have been implemented via desugaring at parse-time,
but yield* is an expression, and its desugaring includes statements like
while and try/catch.  We'd have to have BlockExpression in the AST to
support that, and it's not worth it for this feature.

So instead we implement all of the logic in
FullCodeGenerator::VisitYield.  Delegating yield AST nodes now have a
try handler index, for the try/catch.  Otherwise the implementation is
straightforward.

75d939aceb Generators save and restore stack handlers 
This CL adds machinery to unwind stack handlers from the stack and store
them into a generator's operand array.  It also includes routines to
reinstate them.  Together this allows generators to yield within
try/catch and try/finally blocks.
