3b08a1f82c Added new GetHeapStatistics API entry and deprecated old one. 
Simplified the HeapStatistics class a bit, following Uncle Bob's advice that
adding accessors to DTOs only satisfies some design fundamentalists, but serves
no other purpose. :-)

1ac3949a93 Removed deprecated functions from v8's external API. 
Removed the following deprecated functions:

   * Object::GetPointerFromInternalField
   * Object::SetPointerInInternalField
   * External::Wrap
   * External::Unwrap
   * Context::GetData
   * Context::SetData

They have been deprecated in the 3.15 branch and are not used by Chrome anymore.
Furthermore, judging from bug reports and email threads, embedders like node.js
and others are already using 3.15, too. All removed API entries can be emulated
by a one-liner, so adapting should not be hard for anybody.

We want to introduce more deprecations soon, but to keep things simple and avoid
having old and not-so-old deprecations in v8.h, the 3.15 deprecations are now
removed.

In general, the strategy of keeping deprecated things for one stable release and
then removing them seems to be a good compromise between a maintenance nightmare
and annoying external embedders. :-)

4cd41edcd9 Add methods to allow resuming execution after calling TerminateExecution(). 
Two new methods are added to allow embedders to determine that execution
should be resumed at a particular point in the stack without being forced
to unwind all JS frames.

* V8::ResumeExecution() -- When execution is terminated via a call to
  V8::TerminateExecution(), this method can be called to clear the
  termination exception so that the engine can continue to be used.

* TryCatch::HasTerminated() -- When a TryCatch has caught a termination
  exception, HasTerminated() will return true to indicate it is valid to
  call V8::ResumeExecution() if desired.

A test case is added to cctest/test-thread-termination.cc.

cec0745aa2 Introduce callback for resolving global object name while taking heap snapshot 
Heap profiler currently gets "document" of global objects while taking snapshot (to later retrieve its "URL"). This is unsafe as there may be no current v8 context when the property is requested while corresponding property accessor may make some assumptions about the context stack during its invokation. Several crashes were reported due to this problem:
https://bugs.webkit.org/show_bug.cgi?id=103076
https://crbug.com/162121
https://crbug.com/132727

This patch adds a callback for resolving global object names and avoid the crashes.

f3807ca17b Heavy cleanup of the external pointer API. 
Added highly efficient Object::SetAlignedPointerInInternalField and
Object::GetAlignedPointerFromInternalField functions for 2-byte-aligned
pointers. Their non-aligned counterparts Object::GetPointerFromInternalField and
Object::SetPointerInInternalField are now deprecated utility functions.

External is now a true Value again, with New/Value/Cast using a JSObject with an
internal field containing a Foreign. External::Wrap, and External::Unwrap are now
deprecated utility functions.

Added Context::GetEmbedderData and Context::SetEmbedderData. Deprecated
Context::GetData and Context::SetData, these are now only wrappers to access
internal field 0.

Added highly efficient Context::SetAlignedPointerInEmbedderData and
Context::GetAlignedPointerFromEmbedderData functions for 2-byte-aligned
pointers.

37759f4d64 Implement committed physical memory stats for Linux. 
The patch introduces CommittedPhysicalMemory function to
the Heap class that reports committed *physical* memory acquired
for the heap from the OS.
It is important because some OSes may defer actual committment on e.g.
first access to the region.
So reporting just plain committed size led to various weird artifacts
like showing V8 allocated memory higher than the whole process
private size.

In WebKit, we have a small integer cache because calling v8::Integer::New is
slow. This patch adds a faster API for creating integers that requires the
caller to supply the v8::Isolate, saving us the work of looking up the isolate

9dc2c5b83d Add an API for enumerating persistent handles 
This API lets the embedder enumerate handles that have class ids. WebKit will
use this feature during garbage collection to compute object groups for DOM
nodes. Previously, we kept a list of DOM nodes on the WebKit side, but that
list is redundant with the global handles list in V8.

lots of exciting per-context data. The current API restricts us to storing only
Strings, which is less useful.

ccc827a6f8 Allocate block-scoped global bindings to global context. 
- The global object has a reference to the current global scope chain.
  Running a script adds to the chain if it contains global lexical declarations.
- Scripts are executed relative to a global, not a native context.
- Harmony let and const bindings are allocated to the innermost global context;
  var and function still live on the global object.
  (Lexical bindings are not reflected on the global object at all,
  but that will probably change later using accessors, as for modules.)
- Compilation of scripts now needs a (global) context (previously only eval did).
- The global scope chain represents one logical scope, so collision tests take
  the chain into account.

71618ee6aa The deferred handes list belongs to the Isolate and not to the 
HandleScopeImplementer (since it isn't something specific to a
particular thread executing on an Isolate). This patch ensures correct
traversal of the handles when when multiple compilations are queued
up.

  - heap profiler now makes one pass less over the heap.
  - HeapEntriesMap does not allocate EntryInfo per each entry.
  - there's no need for an extra pass to set indexes before serialization.

As a result snapshot taking time has reduced up to 2x times.

63f033576c Fix performance regressions due to lazy initialization. 
This CL:
- Adds a new trait parameter to LazyInstance to let it initialize the instance
  without paying the cost of atomic operations (which are expensive on Mac).
  This only works for users who don't care about thread-safety and this is now
the default initialization trait used by LazyInstance in v8.

- Reverts the changes that were made in r11010 in isolate.{cc,h}. That lets
  Isolate's accessors be as cheap as they were before (but adds one static initializer).

- Adds OS::PostSetup() used to initialize the math functions which depend on CPU features.
That lets the math functions get rid of CallOnce().

4cb600962f Make setting of accessors even more atomic. 
Now the whole getter/setter/attributes triple gets created/set together,
avoiding any hacks regarding previous values/attributes, making things a lot
simpler.

While doing this, an interesting problem surfaced, which has been there for a
long time: After adding/changing acessors in slow mode, we could potentially
fail going back to fast mode because of a failed memory allocation, signaling
the need for a GC. But we have already changed the object in slow mode, so we
are not idempotent and the retry would trigger a newly inserted assertion
(namely, that the code obeys access restrictions). This has been solved by
splitting the transformation to fast mode from the actual setting of the
accessors.

1f7d42efc9 Landing for pliard@chromium.org: Remove static initializers in v8. 
This change includes two CLs by pliard@chromium.org:

1. http://codereview.chromium.org/9447052/ (Add CallOnce() and simple LazyInstance implementation):

Note that this implementation of LazyInstance does not handle global destructors (i.e. the lazy instances are never deleted).

This CL was initially reviewed on codereview.appspot.com:
http://codereview.appspot.com/5687064/



2.  http://codereview.chromium.org/9455088/ (Remove static initializers in v8):
This CL depends on CL 9447052 (adding CallOnce and LazyInstance).
It is based on a patch sent by Digit.

With this patch applied, we have only one static initializer left (in atomicops_internals_x86_gcc.cc). This static initializer populates a structure used by x86 atomic operations. It seems that we can hardly remove it. If possible, it will be removed in a next CL. 

This CL also modifies the presubmit script to check the number of static initializers.

f4f4bd0a46 We have a problem with really big apps. The snapshot for such pages doesn't fit into JS heap on DevTools front-end side. I'd like to move the snapshot's nodes data into Int32Array. 
This will reduce the pressure. At this moment it is not possible because the snapshot uses uint64_t for ids.

1a356cff3e Fix redefinition of aliased elements in arguments. 
This refactors the way we (re)define elements to perform normalization
and attribute updating at a much deeper level, thereby removing some
bogus special cases in upper runtime layers.

Most element setters take an indicator flag that distinguishes between
setting and defining. Setting of an element causes attributes to remain
unchanged, writability to be checked and callbacks to be called.
Defining of an element causes attributes to be updated and callbacks to
be overridden. The same approach could be taken for properties.

8e31371d0e Move logic for hidden properties into the JSObject. 
Previously, the logic using the hidden properties backing object was
spread accross use sites. Now it's all contained in JSObject, with
only simple accessors available.
Also change the backing object to be a StringDictionary rather than a JSObject.
There's still room for improvement by making a hash-table that don't
store property details as well.

615add8463 Expose APIs for detecting boxed primitives, native errors and Math. 
While implementing structured clone I found that I need support
for detecting and creating objects using the builtin Number, String
and Boolean constructors; this CL adds this support. I also need
to be able to detect entities of "native object type (e.g., Error)",
hence the new IsNativeError() calls.

508b22c436 "Deiceolate" Thread classes. 
Thread class was receiving an isolate parameter by default.
This approact violates the assumption that only VM threads
can have an associated isolate, and can lead to troubles,
because accessing the same isolate from different threads
leads to race conditions.

This was found by investigating mysterious failures of the
CPU profiler layout test on Linux Chromium. As almost all
threads were associated with some isolate, the sampler was
trying to sample them.

As a side effect, we have also fixed the DebuggerAgent test.

Thanks to Vitaly for help in fixing isolates handling!

5872e8ee2f Refactor storage of global handles. 
We used to have a linked list of nodes that were internally
block-allocated.

I kept the node blocks and put them on two lists: 1) the list of all
allocated blocks, 2) the list of blocks with used nodes. (1) is used
to reclaim blocks and (2) is used for traversal during GC. To make
traversal on scavenges faster the nodes holding new space objects are
grouped in an auxiliary array.

This changes the minimal memory usage from 5 words per global handle
to 4. Additional word is used for new space handles.

ec58c05f4e Add support for startup data (snapshot) compression. 
This is for mobile platforms where application footprint size is
important. To avoid including compression libraries into V8, we assume
that the host machine have them (true for Linux), and rely on embedder
to provide decompressed data.

Currently, only snapshot data can be comressed. It is also possible to
compress libraries sources, but it is more involved and will be
addressed in another CL.

302037d44e Make object groups and implicit references a bit more lightweight. 
We can only call malloc/free once per group and we can avoid scanning
through a list of NULLs if we keep unprocessed groups in the beginning.

I also changed the internal representation of implicit references to
hold a handle to the parent (instead of a direct pointer). The
prologue callback must not trigger a GC, but it's better to be safe.

Add a call to deoptimize all functions after running tests with --stress-opt. This will catch some issues with functions which cannot be forcefully deoptimized. Some of the tests failed on ARM with that change without the rest of the changes in this change.

- There's a new constant in v8.h for external arrays with pixel array elements.

5cf643aa42 New heap profiler: add support for progress reporting and control. 
As taking a snapshot of a large heap takes noticeable time, it's
good to be able to monitor and control it.

The change itself is small, big code deletes and additions are in
fact moves. The only significant change is simplification of
approximated retained sizes calculation algorithm.

Otherwise, retaned memory sizes are not precise. This increases size
of heap snapshot, I will deal with this later. Heap objects and
references previously missing in snapshot are now marked as 'hidden'.
That means, they not shown to user, but participate in sizes
calculation.

Other small changes:
 - added 'shortcut' graph edges: e.g. to pin global objects on top
   level;
 - meta-information in JSON snapshot is no more double encoded.
