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.

For keyed IC loads setting a break point now ensures that the inlined code is not used. When the break point is set the inlined map check is changed to fail causing the inlined code not to be used but the IC to be called. As long at the break point is set the map check will stay invalid.

ea48d53bad Add ENABLE_DEBUGGER_SUPPORT macro. 
ENABLE_DEBUGGER_SUPPORT is enabled by default unless it is on Android platform.
On Android platform, it can also enabled by passing -DENABLE_DEBUGGER_SUPPORT flag to the compiler.

This should not affect any existing build (I hope, cross my fingers) except the build in real Android environment (in other word, it only affects me now).

There are lot of room for code refactoring in stead of using #ifdef all over the place. I will leave this to v8 folks.

59d4539f38 If an external string enters the symbol table, make sure to set the 
resource to NULL when removing it from the symbol table.  This makes
sure that the debugger can recognize the external string as being
"deleted".  Now, whenever an external resource is deleted, the
resource pointer is set to NULL.

This is really a workaround of a debugger problem.  We need to make
sure that the debugger only finds scripts in the heap that are
actually live.

3c2a7bdf21 Add name inference for anonymous functions to facilitate debugging and profiling of JS code. 
Currently function name inference is wired with AST optimization pass to avoid introducing another pass over AST. A better solution would be to rewrite AST visitors so they can be naturally combined together in a single pass, as their current implementation doesn't allow it.

For examples of cases where function names can be inferred, see the tests file.

0eb4dea12d Implemented "no heap access" mode for JSFrame which is used for stack sampling in profiler. 
As I discovered that JSFrame accesses SharedFunctionInfo only to calculate caller SP and the latter is not used in profiler's stack sampling, I disabled accessing heap objects in JSFrame when doing stack sampling. This finally made V8's profiling stable when used from Chrome on a real web app.

a74fcf458c Fixed the step in handling for function.apply. 
The generic step-in mechanism floods the function called with break points to ensure a break is hit when entering the function. This generic mechanism was also used for function.apply. The code for function.apply contains a keyed load IC which was patched when stepping into function.apply. However function.apply enteres an internal frame not a JavaScript frame. This caused the logic for returning from the break in function.apply to fail as it forced a jump to the IC on the top JavaScript frame. The top JavaScript frame was the frame for the function calling function.apply not the frame for the apply function. Now returning from the break point in the keyed load IC in the apply code caused a jump to the code for the call IC for the function calling function.apply in the first place. Not a pretty sight.

Step-in now handles function.apply as a separate case where the actual JavaScript function called through apply is flodded with breakpoints instead of the function.apply function.

This means that IsDeadCeck and EnsureInitialized could sometimes be
called without having already entered the VM.  To simplify things,
this is made always the case.  A couple of error callbacks do not need
to leave V8 because they haven't entered.

Consistently enter V8 after LOG_API (since LOG_API is sometimes before
EnsureInitialized or IsDeadCheck).

This all should have no effect unless V8 is built with
ENABLE_HEAP_PROTECTION and run with --protect-heap.

aacd90314f Reland exception propagation fix. 
Fix exception propagation problem where undefined was returned instead
of an empty handle in case of an exception.  This problem can break
C++ programs that are not interested in catching exceptions and just
want to propagate them out by testing for empty handles.

The issue is that exceptions are not rescheduled if they are
externally caught.  Externally caught exceptions have to be
rescheduled if there is a JavaScript frame on the way to the C++ frame
that holds the external handler.

A couple of tests will fail on the ARM simulator because the simulator
has separate stacks for C++ and JavaScript.  I have marked the tests
as failing only on the simulator.

1f7a7d9c58 Change handling of debugger unloading. 
Add a semaphore for accessing debugger varaibles which can be changed from a different thread. This is mainly the debug message handler which can be set to NULL to disconnect the debugger.

Control the unloading of the debugger from the V8 thread. Before the debugger unload was called from the thread setting the debug message handler to NULL. This was not safe as this involves calling into V8. This change handles the unloading of the debugger either when entering a debugger event and the debugger was disconnected while the debugger was not active or when leaving the debugger and the debugger was disconnected while the debugger was active.

Add a flag to avoid unloading the debugger if debugger code is used by the application for other purposes than debugging.

Added tests for clearing the debug message handler.

These state changes are only taken when built with

8b7a288e48 Debugger message handler can be called from V8 thread. 
The message handler function set through the debugger API is normally called in a different thread than the V8 thread where execution is stopped due to debugger event. This change adds an option to the API for specifying that the message handler should be called directly from the V8 thread. For an application like Chrome where thread dispatching is already in place this makes more sense.

Add an option to the message handler debugger API to process messages in the thread where V8 is running instead of posting it to a queue for processing on a additional thread.

03419c8369 Simplify the way the code generator handles calls to IC stubs. Before 
we dispatched on the IC stub kind in a generic CallCodeObject
function.  Now, we have special functions for the load and store IC
stubs.

We also (for the load and store ICs) handle moving register arguments
into place only after the stack is prepared for the call.  This
replaces some memory-to-memory moves (for copies whose backing store
is occupied by a register needed for the arguments) with
memory-to-register moves.

96088babe7 Add a new "pseudo" platform for POSIX. It it will contain code shared by the platforms supporting POSIX. Currently Linux, Mac OS and FreeBSD are considered POSIX platforms using the POSIX implementation. 
Initially the platform socket implementation has been moved from the Linux, Mac OS and FreeBSD platforms to the POSIX platform.

If implementation which ends up in the POSIX platform at some point cannot be the same across POSIX platforms the implementation can easily be moved back into the individual POSIX "complient" platforms.

32de098ef6 Allow the debugger agent to reuse ports stuck in TIME_WAIT for listening. 
When the debugger agent terminates the used port can be stuck in TIME_WAIT for some time depending on the OS and the state of the socket. With this change will allow the debug agent to start listening on a port still in TIME_WAIT. During development of both V8 and embedding applications this makes it much easier to restart an application using the debugger agent.

This also makes it possible to run the tests involving the debugger agent multiple times without failure.

f060eb3293 Changed preemption related stuff in debugger entry. 
Fixed an assertion which did not hold when the debugger was recursively entered.

Removed the clearing of the preemption flag in debugger entry as there was no need for it. The handling of preemption by the stack guard takes care of the in debugger situation anyway.

8dffcb9efa Flush ICs when adding setters to an object or setting a __proto__ to 
an object that holds a setter.  If there are no store ics then no
flushing is done.  The implementation has been tweaked so that no ICs
are cleared during normal context creation.
This may cost us some performance but I'm submitting it as it is and
if there are problems we can either decide to be smarter about when,
what and/or how we clear, or back this change out altogether.

17b498c957 A new stack guard break flag DEBUGCOMMAND has been introduced. This is used to signal debug break due to debugger commands available in the queue for processing. If a stack guard break happens with this flag and not the DEBUGBREAK flag the no debug break event is generated and execution is resumed automatically when all debugger commands in the queue has been processed. 
This makes it possible to remote debuggers to just add commands to the queue without having to request a break as well. As soon as any JavaScript executes the debugger commands will be processed and the response send to the remote debugger.

Currently hide this behind a flag (--debugger-auto-break) as the current command line debugger in Chrome is not designed for this new behaviour, whereas the new Chrome developer tools will use it.

C++ programs that are not interested in catching exceptions and just

The issue is that exceptions are not rescheduled if they are

rescheduled if there is a JavaScript frame on the way to the C++ frame
that holds the external handler.

9d17b0d4c8 Whenever a script object is created it is assigned a unique id. Currently this id is assigned from an 32 bit integer counter. 
Changed the script break points to be able to handle both break points based on script names and script ids. When break points are set through a script id the position is relative to the script itself. This is different from the script break points set through script names where the line/coulmn offset is taken into account.

This has the side effect that function break points are not converted into script break points for named scripts.

Show the script id in the D8 shell debugger when listing all scripts using the 'scripts' command.

ece2c03160 Fix issue 263: 
http://code.google.com/p/v8/issues/detail?id=263

Sharing the code to unlink the exception handler for a try/finally
causes us to try to merge virtual frames with different heights (due
to statements that keep state on the stack) at the entry to the unlink
code.

Avoid this by unlinking the handler separately for each exit from the
try block.

747e20c449 Mark the empty script object, the script for the empty function and the D8 utility script as native scripts. 
This is mainly to avoid these scripts showing up in the debugger when showing normal scripts.

Removed the check for the empty script in the debugger function returning loaded scripts as this check only filtered out the empty script from the debugger context and not empty scripts in all other contexts. Also this filter did not take the script for the empty function into account.

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.

The D8 debugger frontend now only processes JSON messages. Before the debugger events was passed as objects.

Changed the debugger events JSON generation to use the same serailizer as the responses to requests. This provides correct serialization of mirror objects in debugger events. Renamed ResponsePacket to ProtocolMessage as it is not only used for responses.

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.

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.

Building with MinGW has been tested with version 5.1.4 using GCC 3.4.5.

In addition to supporting MinGW this change also makes it more explicit which targets needs to link with which libraries.

269763d51b Reduce the size of a release sample shell by 55k. 
The ExternalReferenceTable population code was code driven, using the list macro callbacks to call an Add() function.  Additionally this Add() function was defined in the class defintion, making it inline.  This caused this single function to be ~100k of code.  It is now mostly table driven, but there are still some cases left as code, and these could be improved in the future for further reduction in binary size.

260cd876d1 Eliminate the code that handles fallback to JSCRE. The only way to get 
JSCRE now is to use the --noirregexp flag.  Also add code to check that
we react sensibly to some very large regexps.

01198feda3 A field might be incorrectly set, causing registers to be pushed and popped 
instead of just cleared on backtrack - or, worse, the other way around!

Allows backtracking to clear registers instead of pushing and popping
them to restore state.

335a73aa4b Added a simple wrapping of the debugger JSON responses. 
Added a 'dir' command to the command line debugger to display the details of an object including the handle number for the object and the objects that it references.

Added the ability to use #XXX# to a 'print' or 'dir' request. XXX is the handle number for the object.
