1. The tables array allocated in the CompilationSubCache constructor
was never deallocated. Fixed by adding destructor.
2. The buffer allocated in one of the constructors of the
NoAllocationStringAllocator was never deallocated. It seems that
this class sometimes owns the buffer (if it allocated one itself)
and sometimes doesn't (if it was passed one). Simple fix is to
remove the offending constructor which was never used anyway.

Add a trace_gc_verbose flag.
...
The flag is only turned on when --trace_gc is one. It prints out used and available bytes in each space. To enable it, ENABLE_LOGGING_AND_PROFILING must be defined.
This is a mini version of --heap_stats, but don't need DEBUG macro to be turned on.

In Chrome several tabs may share the same v8 instance. Each of those tabs can be inspected with its own devtools window. When such devtools window closes we need to clear all breakpoints that belong to it. Notion of breakpoint group enables us to do that.
...
Storing the breakpoints on the client(in a different process) would be inreliable since 1) it may crash and 2) some 'setbreakpoint' requests may be not processed yet by the time devtools window closes.

Add a map from names to variables for global scopes just like
non-global scopes. Variables are added to the map by the parser when
it encounters a declaration in a global scope or else at scope
resolution time by a failed variable lookup from the global scope or
an inner one and with no intervening with statements or possible calls
to eval.

Handle JavaScript accessors on the global object.
...
With the new representation of the global object adding JavaScript accessors for a property after global inline caches was created for that property did not work property as the inline caches did not take the JavaScript accessor information (fixed array with two elements) that could be present in a global object property cell into account.
This is now fixed by changing the map for a global object when a JavaScript accessor is defined on it.

Reimplement profiler sampler on Mac OS X to get it working under Chromium.
...
Previous implementation of sampler for OS X was copied from the Linux one. But BSD (OS X) and Linux has a very important difference in signal handling. LinuxThreads doesn't support the notion of process-directed signals. So, the SIGPROF signal was directed to the thread that installed the handler---the V8 thread. But on BSD, signal handling is implemented according to POSIX spec, where process-directed signal is to be handled by an arbitrary selected thread. By a coincidence, in V8's sample shell and in Chromium's test shell, V8's thread was picked almost every time, so sampling seemed working. But not in case of Chromium.
So, I've changed the implementation of profiler sampler to use the same scheme as on Windows---a dedicated thread with high priority is used to periodically pause and sample V8's thread.

When Error.collectStackTraces is set to true all new instances of
...
Error, ReferenceError, etc. are given a stack property that gives a
stack trace. Here's an example stack trace:
ReferenceError: FAIL is not defined
at Constraint.execute (deltablue.js:527)
at Constraint.recalculate (deltablue.js:426)
at Planner.addPropagate (deltablue.js:703)
at Constraint.satisfy (deltablue.js:186)
at Planner.incrementalAdd (deltablue.js:593)
at Constraint.addConstraint (deltablue.js:164)
at Constraint.BinaryConstraint (deltablue.js:348)
at Constraint.EqualityConstraint (deltablue.js:517)
at chainTest (deltablue.js:809)
at deltaBlue (deltablue.js:881)
at deltablue.js:888
If Error.prepareStackTrace holds a function this function is used to
format the stack trace, for instance allowing code generators to
customize the way stack traces are reported to make them easier to
process.
Next step: performance measurements to see if it is feasible to turn
this on by default.

Changed the global object representation.The global object is now always in dictionary (slow) mode with each of its properties stored in a cell object. A cell object has one field containing the actual value for the property. Inline caches for access to global properties which uses direct to the cell are now created for load, store and call to properties of the global object. When properties of the global object are deleted the cell for that property is kept with an indcation of that the property is deleted.Added counters to track the use of the global property inline caches.Added additional information on IC's in the disassembler.

Make some small Mac-specific modifications to V8 to make it work on MacOS X 10.4
...
rather than just 10.5 and up.
1: Set the right compile flags and predefines to get backward compatible Unix
system calls.
2: Explicitly weak import the functions in execinfo.h and check at runtime to
see if that library loaded before calling backtrace().

Added utility scripts for running oprofile in tools/oprofile.
...
To profile running the JavaScript file test.js using the V8 release mode shell (assuming it is build passing prof=oprofile to the SCons build). The following commands can be used:
$ tools/oprofile/start
$ tools/oprofile/run test.js
$ tools/oprofile/report | less
$ tools/oprofile/annotate | less
$ tools/oprofile/shutdown
Here is a summary of the commands.
For all the commands taking an executable the executable is expected to be a binary using V8. If no executable is specified the release mode V8 shell is assumed.
By default the --session-dir=/tmp/oprofv8 is passed to all oprofile commands. This walue can be changed by setting environment variable OPROFILE_SESSION_DIR.
When using the defaulf executable (V8 shell in release mode) it is assumed to be located in ../.. relative from the oprofile utility scripts. This default location can be overridden using the V8_SHELL_DIR environment variable.
start
-----
Start the oprofiling daemon.
run [executable] [parameters]
-----------------------------
Profile a V8 executable. Running this will reset oprofile samples, run the command and do an oprofile dump to flush samples and write ELF binaries for the generated code. The parameters are passed to the executable together with the --oprofile option.
report [executable] [parameters]
--------------------------------
Print the report for a profile run. The parameters are passed to opreport. E.g report --callgraph.
annotate [executable] [parameters]
----------------------------------
Print annotated assembly for a profile run. The parameters are passed to opannotate. E.g annotate -threshold 1.
reset
-----
Reset oprofile samples.
dump
----
Flush oprofile samples and write ELF binaries for the generated code.
shutdown
--------
Shutdown oprofile daemon.
Added a warning which is printed if option --oprofile is passed to a V8 which has not been compiled with oprofile support.

Involve more log compression techniques.
...
Code addresses are now written as an offset from the previous address for ticks, code move and delete events. Employed backreference and RLE compression for code move and delete events. This gives additional 30% log size reduction for benchmarks run w/o snapshot.
Overall compression results (compared with the revision of V8 having no compression):
- V8: 70% size reduction for benchmarks run w/o snapshot (for reference, gzip gives 87%)
- Chromium: 65% size reduction for public html version of benchmarks (v4) (for reference, gzip gives 90%)
The one obvious opportunity for improving compression results in Chromium is to compress URLs of scripts.

Add scope chain information to the debugger.
...
For each frame it is now possible to request information on the scope chain. Each scope in the chain can have one of the types local, global, with and closure. For scopes of type global and with the mirror for the actual global or with object is available. For scopes of type local and closure a plain JavaScript object with the materialized content of the scope is created and its mirror is returned. Depending on the level of possible optimization the content of the materialized local and closure scopes might only contain the names which are actually used.
To iterate the scope chain an iterator ScopeIterator have been added which can provide the type of each scope for each part of the chain. This iterator creates an artificial local scope whenever that is present as the context chain does not include the local scope.
To avoid caching the mirror objects for the materialized the local and closure scopes transient mirrors have been added. They have negative handles and cannot be retrieved by subsequent lookup calls. Their content is part of a single response.
For debugging purposes an additional runtime function DebugPrintScopes is been added.
Added commands 'scopes' and 'scope' to the developer shell and fixed the dir command.

Implement tick events compression in a log file.
...
Two techniques are involved:
- compress repeated line ends (common stack beginnings) by using back references;
- do RLE compression of repeated tick events.
This gives only 5% size reduction on benchmarks run, but this is because tick events are only comprise 10% of file size. Under Chromium winnings are bigger because long repeated samples of idleness are now compressed into a single line.
Tickprocessor will be updated in the next patch.

This is a trivial per-row compression:

- in tick events, offsets are used instead of absolute addresses;

Add more debugging information to scripts compiled through eval.
...
Scripts now have a compilation type which can be host, eval or JSON. Host scripts are compiled through the API, eval scripts are compiled through call to evan and JSON scripts are compiled as a result of calling JSON.parse.
For scripts scripts compiled through eval the JavaScript function in top of the stack and the pc offset into the code is stored in the script object. This makes it possible to calculate the source position of the eval call later when requested. This information can be obtained through the script mirror object and is part of the script mirror JSON serialization for the debugger protocol.
Moved the enumeration ScripType into class Script and remamed to Type. The new compilation type enumeration is also inside the class Script.
This information is now shown when using the scripts command in he developer shell debugger.

Simplify the processing of deferred code in the code generator. Our
...
deferred code snippets are highly stylized. They always make a call
to a stub or the runtime and then return. This change takes advantage
of that.
Creating a deferred code object now captures a snapshot of the
registers in the virtual frame. The registers are automatically saved
on entry to the deferred code and restored on exit.
The clients of deferred code must ensure that there is no change to
the registers in the virtual frame (eg, by allocating which can cause
spilling) or to the stack pointer. That is currently the case.
As a separate change, I will add either code to verify this constraint
or else code to forbid any frame effect.
The deferred code itself does not use the virtual frame or register
allocator (or even the code generator). It is raw macro assembler
code.

Fix determining of JS lower stack bottom used in profiler's JS stack tracer to work with Chromium.
...
My assumption that log initialization happens somewhere near the stack's bottom is true for V8's sample shell but isn't true for Chromium, causing many otherwise valid stack addresses to be thrown out. The solution proposed is to save stack pointer value for the outermost JS function in ThreadLocalTop similar to c_entry_fp.
Implemented only for IA-32. Currently I'm not dealing with profiling on ARM and x86-64 anyway.

Change the handling of the debug break stack guard. The debug break is no longer ignored when hit inside "system" JavaScript. The reason for this is twofold:
...
* Running "system" JavaScript with the debug break flag active leads to slow running code while waiting for the break in non "system" JavaScript (one exception to this it is to try to avoid breaks in the clear mirror cache JavaScript code called when leaving the debugger).
* If this happens while processing RegExp running in native code an infinite loop is created as the stack guard handler for RegExp does not move execution forward
Fixed a GC bug in the interrupt handling for RegExp running in native code.
Added test of debug break while in debug message handler callback and debug break while executing a RegExp.

When profiler's memory buffer is filled up, profiling is stopped and it is ensured that the last record in the buffer is "profiler,\"pause\"" thus making the end of profiling session explicit. Otherwise DevTools Profiler would need to guess whether the current profiling session has been stopped.

Implement a dynamically growing memory log buffer with an upper limit.
...
The goal of this change is to allow longer profiling sessions and preserve memory when profiler isn't started. The buffer starts with 64K and grows until it reaches the upper limit, which is currently set to 50MB --- according to my evaluations, this is enough for at least 20 minutes of GMail profiling. As we're planning to introduce compression for the profiler log, this time boundary will be significantly increased soon.
To make possible unit testing of the new component, I've factored out Logger's utility classes into a separate source file: log-utils.h/cc. Log and LogMessageBuilder are moved there from log.cc without any semantical changes.

This patch much improves our tracking of whether function is
...
called from within a loop or not. In the past we lost the
information if a call site went megamorphic before a lazily
compiled callee was called for the first time. Now we track
that correctly (this is an issue that affects richards).
We still don't manage to track the in-loop state through a
constructor call, since constructor calls use LoadICs instead
of CallICs. This issue affects delta-blue. So in this patch
we assume that lazy compilations that don't happen through a
CallIC happen from inside a loop. I have an idea to fix this
but this patch is big enough already.
With our improved tracking of in-loop state I have switched
off the inlining of in-object loads for code that is not in
a loop. This benefits compile speed. One issue is that
eagerly compiled code now doesn't get the in-object loads
inlined. We need to eagerly compile less code to fix this.

Split nested namespaces declaration in two lines in accordance with C++ Style Guide.
...
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

Implement resource-saving ("lazy") mode of Profiler.
...
This is intended to be used with Chromium. When in resource-saving mode, profiler doesn't consume any resources (sampler and logging is off) until resumed. Then again, when profiler is paused, sampling and logging are turned off.
Tested under Linux and Windows. Also have done preliminary testing with Chromium.

When message handler is set to NULL and there is no debugger listener the debugger is unloaded immediately unless it's entered, in which case it will be unloaded when last instance of EnterDebugger is destroyed.
...
Without the change the debugger may crash as Debugger::EventActive(v8::Break) called from OnDebugBreak may clear current debugger context.
Also when compilation cache was enabled debugger could fail on second attach for the same reason(see AfterCompileMessageWhenMessageHandlerIsReset).

Introduce Logger::LogCompiledFunctions that logs current map of compiled code.
...
The goal is to make possible having --prof flag always enabled in Chromium. Currently we can't do this because --prof causes compiler and gc to log code creations / moves / deletes which aren't needed until we start profiling. With LogCompiledFunctions it will be possible not to log anything until we start profiling. When started, the current map of compiled functions will be logged and compiler / gc logging will be enabled to update current state. When profling is stopped, logging will be turned off again.
Funny that testing code is actually much longer and complex than function code.

Add a script cache to the debugger
...
When loaded scripts are requested this cache is filled with all the script objects in the heap. Hereafter its content is kept in sync with the active scripts in the heap through the notifications of new scripts compiled and by using weak handles to get notified when a script is collected.
Through the tracking of collected scripts the debugger event OnScriptCollected have been added to notify a debugger that a script previously returned through the scripts command is no longer in use.
Make the ComputeIntegerHash globally available.
Moved clearing of the mirror cache to when debugger is really left. Previously recursive invocations of the debugger cause the mirror cache to be cleared causing handles to become either stale or reference other objects.

If 'compactFormat' argument is passed in the request the response won't include referenced mirrors in the refs section instead each protocol reference object will contain some details necessary for displaying the referenced object in the graphical debugger when the object is not expanded. That allows to request full information lazily when the object is expanded.

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.

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).

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.

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.

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.

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.

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.

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

larger than one.

ENABLE_DEBUGGER_SUPPORT is enabled by default unless it is on Android platform.

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.

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.

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.

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.

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.

V8's heap or only need read access.
This means that IsDeadCeck and EnsureInitialized could sometimes be

this is made always the case. A couple of error callbacks do not need

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.

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.
