22d6605f2f All preemption requests are now ignored while in the debugger. This ensures that no change of V8 thread happenes while in the debugger. The only thing that happens is that a flag is set to indicate that preemption happened. When the debugger is left preemption is requested if it occourred while in the debugger. 
Moved the debugger related global variables from Top to thread local in Debug.

b638d5c613 Fix issue 259. 
http://code.google.com/p/v8/issues/detail?id=259

Due to constant folding of loop conditions, it is possible to have a
try/finally with no exits from the try block (eg, an infinite loop in
the try block).  In that case the code to unlink the try handler is
dead and should not be emitted.

3db607a3c4 Dump more stack frames to perf log when executing a C++ function. 
JavaScriptFrameIterator is templatized on the iterator type and renamed to JavaScriptFrameIteratorTemp.
The original JSFI is now a typedef for JavaScriptFrameIteratorTemp<StackFrameIterator>. Because of templatizing, JSFI code is moved to frames-inl.h

StackTraceFrameIterator moved to frames.*

Implemented SafeStackFrameIterator which wraps StackFrameIterator and have the same interface. It performs additional checks of stack addresses prior to delegating to StackFrameIterator. SafeSFI is used in an another specialization of JavaScriptFrameIteratorTemp template to perform safe JS frames iteration on sampler ticks.

I haven't took an advantage of having multiple stack frames in tickprocessor yet.

be059966c1 Add socket support to platform code. 
The new Socket class is an encapsulation of the standard BSD socket API. As it depends on platform specific include files and have some slight platform variations it is part of the platform code.

On Mac OS only the option SO_REUSEADDR is set to true for server sockets. Running the test required it as the bound listener socket would sometimes end up in TIME_WAIT. On Windows and Linux this has never been observed (given the client end of the socket is closed before the server end).

The code has been tested on Windows, Linux and Mac OS. The FreeBSD version is a copy of the Linux version but has not been compiled nor tested.

Missing Xcode project updates.

the variable could be global we check context extension objects at

44b83d3e77 Add host callback for debug break. 
Add the ability to have the host embedding V8 receive a callback in the V8 thread while V8 is processing a debug callback. When V8 is processing a debug callback the thread where V8 is executing is sitting in a tight loop processing debug commands until the continue command has been executed. In some embedding situations it is beneficial to be able to call back into the embedding host from the thread where V8 is sitting. The might have functions which needs to be called to complement the JavaScript debugging.

Using the uint16_t array to pass a void* is a temporary hack.

a09832ab76 Optimize loads from variables that might be shadowed by variables 
introduced by eval.

In the cases where calls to eval have not introduced any variables, we
do not need to perform a runtime call.  Instead, we verify that the
context extension objects have not been created and perform a direct
load.

Not implemented for ARM yet and the scope resolution code could use
some better abstractions.  I'd like to do that in a separate
changelist.
