ada3d37219 Added support to backtrace from botton of stack to debugger protocol. 
Fixed backtrace in D8 debugger and added gdb like syntax 'bt n' and 'bt -n' in addition to the already existing 'bt from to'.

83f2c1968f Streamline JumpTarget::ComputeEntryFrame by removing the separate loop 
that sets the static type on elements in the entry frame.  Instead set
the static type as early as possible when computing elements.

Because the elements are shared with the reaching frames, this has the
side effect of sometimes changing the static type of reaching frame
elements.  They will be changed anyway in VirtualFrame::PrepareMergeTo
immediately after, so this is safe.

5fab2d08f2 A register allocation bugfix. 
The function that prepares a virtual frame slot for writing (in order
to preserve the copy-on-write semantics of aliased frame elements) can
allocate registers, which may spill one from the frame.  If we're
unlucky, the spilled register can be the source register for the frame
element write.  In that case, ensure we do the write from memory.

bd3019f2b6 Changed the PageIterator class so that it only returns pages existing 
at construction time.  If allocation during iteration causes a paged
space to expand, the iterator will not return the new pages.

This makes it more closely match the HeapObjectIterator behavior, and
it removes a possible source of bugs (if the allocation top was in the
last page in the space, the old iterator would stop only when it
reached the end of the space, potentially returning invalid pages from
a freshly expanded space).

b32d7d2e67 Added context information to scripts. 
Added a simple initial version of a context mirror object which just holds the user data from the context, and does not preserve handle identity.

A script object now holds a reference to the custom data from the context it was compiled in. This data is included in the debugger protocol for scripts.

Changed the serialization for the scripts command to use the mirror objects instaed of custom serialization. This included passing options from the debugger request to the serializer for including the full source of scripts in the response.

  This is brought it from the build system.
- HOST, the architecture our C++ compiler is building for.
  This is detected automatically based on compiler defines.

This adds macros for 32 or 64 bit, and cleans up some

e01f3a9ee8 More special handling of the symbol table during garbage collection. 
Mark all objects reachable from the symbols except the symbols
themselves as live (and reachable from strong roots).  This ensures
that if the symbol itself remains alive for any reason, and if it was
a sliced string or cons string backed by an external string, then the
external string will be strongly reachable and therefore not get a
weak reference callback.

ecd705813f A simple fix of issue http://code.google.com/p/chromium/issues/detail?id=3285 
NPN_Construct allows a NPObject to be called as a construct. For example, the
test case

var s = new app.Packages.java.lang.Integer(5);

app.Packages.java.lang.Integer is a NPObject, and it implements NPN_Construct.

This fix allows a JSObject created by an API function be called as a construct
if it can be called
as a function. This is done by generating the same code for
var s = new app.Packages.java.lang.Integer(5); as
var s = app.Packages.java.lang.Integer(5);

and the caller handles both case correctly. A more sophiscated fix is to one
extra JSConstructCall
frame and allow CallAsConstructor in Builtin::HandleApiCallAsFunction.

This change itself shouldn't affect the semantic of normal case such as:

var a = {};
var s = new a();

A TypeError exception will be thrown in CALL_NON_FUNCTION (runtime.js).

Another part of fix is in the binding code, V8NPObject, which makes
NPN_InvokeDefault or NPN_Construct
call depending on which function is available.

a470847226 Added better version information 
The current version is now held in src/version.cc in a number of defines which needs to be modified when changing version.

The following defines make up the version information:

  MAJOR_VERSION
  MINOR_VERSION
  BUILD_NUMBER
  PATCH_LEVEL
  CANDIDATE_VERSION

The first four are numbers and the fifth is a boolean. Besides these five the define

  SONAME

can be used to set a specific soname when building the a shared library (see below). This will most likely be used on stable branches where binary compatibility is ensured between different versions. This define is a string.

This version information is now read by the SCons build to support setting the soname for a Linux shared library. This requires passing the option soname=on to the SCons build.

When soname=on is specified the soname for the shared library can be set in two different ways. Either it will be the full versioned library name (e.g. libv8-1.2.2.so) or a specific soname defined in src/version.cc. Whenever a shared library is build with an soname the filename of the library will hold the full version name (e.g. libv8-1.2.2.so).

I did not update the xcode project with the new files.

95288e916e Changed the debugger message API to receive an object instead of a JSON string. 
The object delivered to the debug message handler contains additional information on the current break handling the messages.

Clients which require just JSON message parsing can simply get the JSON using the GetJSON message on the message object to still have the previous behaviour.

  NewMessageHangler(const v8::Debug::Message& message) {
    v8::String::Value val(message.GetJSON());
    OldMessageHandler(Vector<uint16_t>(const_cast<uint16_t*>(*val), val.length()));
  }

Refactored some of the debugger code to use internal handles instead of API handles. Also changed Object to JSObject is some places.

The access to the active context when the break occurred is still not implemented. I will add this in a new CL, as this one is quite big already.

f6bafbfb09 Prepare push of version 1.2.1 to trunk. The main reason for this push 
is to get the chromium V8-latest builder working again and to move the
gyp file used for the chromium build to V8 to make it easier to roll
V8 DEPS.

4a909a7a62 - When cloning maps to set the 'lazy loading' bit remember to clone 
the properties as well.  This fixes some failing tests.
- Moved json parsing into native code.

8fefc769f5 Removed the debug message thread. 
The debug message thread was introduced to make it possible to have the message handler callback be called from a different thread than the thread running V8 where the debug event occoured, but it never had any practical use, and prevents providing information to the message handler which is only available from the V8 thread.

In the future any thread decoupling will have do be done by the embedder.

This also removes the queue used for outbound messages.

Renamed the class Message to CommandMessage as it is only used for debugger commands from the client. Related message queue classes has also been renamed.

cc0c8d178f Materializing a frame element on the stack by pushing it can cause the 
stack pointer to change by more than one in a corner case.  If we push
a constant smi larger than 16 bits, we push it via a temporary
register.  Allocating the temporary can cause a register to be spilled
from the frame somewhere above the stack pointer.

As a fix, do not use pushes to materialize ranges of elements of size
larger than one.
