be20c55b3e Change RegExp syntax to fail on invalid ranges like [\d-x], [x-\d] and [\d-\d]. 
The previous behavior was to treat the "-" as verbatim if the range was invalid.
This change matches the JSC changeset http://trac.webkit.org/changeset/72813/

correct decoding of positions. This was error prone and made liveedit

1cfc63cf8a New heap profiler: implement fast retaining sizes approximation. 
Approximation is done by building a dominators tree for the heap graph.
Dominator nodes and retained sizes are serialized into JSON.

Removed:
 - reachable size (it is useless, after all);
 - HeapEntryCalculatedData (size is now stored in the node, retaining
   paths in a hash map);

051f314a99 New heap profiler: include all heap objects and refs into snapshot. 
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.

2a8eb35548 Provide more accurate results about used heap size via GetHeapStatistics. 
I observed that used heap size provided by Heap::SizeOfObjects() is
usually about ~10% bigger than the number calculated by summing up
heap objects sizes.

This aligns DevTools Timeline stats with Heap profiler stats.

Instead of relying on itimer signals from kernel, send them

9673ee5d59 Get rid of requested size in RetryAfterGC. 
This was only used by Heap::CollectGarbage to check if after GC
available space is bigger than was requested, but nobody checked
the value returned by Heap::CollectGarbage, so requested size
was efficiently unused.

However, it may trigger spurious out of memory exceptions if requested
size is big enough.

d4bc8e1585 New Heap profiler: add dumping HeapNumbers and InternalFields to snapshot. 
HeapNumbers do consume memory, so it's worth dumping them. However, we
don't dump their values, as they are not as self-descriptive as values
of strings, and they will increase snapshot size. Storing heap numbers
values can be added if we will feel a sufficient demand for that.

InternalFields are used, e.g. for storing references to DOM nodes
event handlers.

cfbc1eed9c Prevent modification of cached normalized maps. 
Finally sovles the problem that r5342 attempted to solve.
When adding a stub to a map's code cache we need to make
sure that this map is not used by object that do not need
this stub.

Existing solution had 2 flaws:
1. It checked that the map is cached by asking the current context.
If the object escaped into another context then NormalizedMapCache::Contains
returns false negative.

2. If a map gets evicted from the cache we should not try to modify it
even though Contains returns false.

This patch implements much less fragile solution of the same problem:
A map now has a flag (is_shared) that is set once the map is added
to a cache, stays set even after the cache eviction, and is cleared
if the object goes back to fast mode.

Added a regression test.

06c867404b Dynamically determine optimal instance size. 
The number of inobject properties used to be derived from the number
of this property assignments in the constructor (and increased by 2 to
allow for properties added later). This very often leads to wasted inobject 
slots.

This patch reclaims some of the unused inobject space by the following method:
 - for each constructor function the first several objects are allocated using the initial 
   ("generous) instance size estimation (this is called 'tracking phase').
 - during the tracking phase map transitions are tracked and actual property counts are collected.
 - at the end of the tracking phase instance sizes in the maps are decreased if necessary
   (starting with the function's initial map and traversing the transition tree).
 - all further allocation use more realistic instance size estimation.

Shrinking generously allocated objects without costly heap traversal is made possible 
by initializing their inobject properties with one_pointer_filler_map (instead of undefined). 

The initial slack for the generous allocation is increased from 2 to 6 which really helps some tests.

2388079051 Implement heap snapshots serialization into JSON. API is designed 
to avoid storing serialized snapshot on VM, instead it is emitted
using output stream interface.

The size of JSON emitted is roughly equal to used heap size
(when stored as an ASCII string).

Now a whole heap snapshot can be serialized and transmitted outside
VM. This makes possible:
  - implementing non-async UI for heap snapshots inspection;
  - storing heap snapshots for further inspection;
  - remote profiling (we can even implement a snapshotting mode
    where a snapshot isn't even stored in VM, only transmitted --
    good for mobile devices);
  - creating tools for outside heap snapshots processing, e.g.
    converting to HPROF.

be5763fc4d Cleanup the way the debugger stores live registers when entering at a break 
The live registers are now only stored to the expression stack with the non pointer values being stored as smis (on the 32-bit platforms these values are assumed to be 31-bit max).

This makes the CEntryStub entry/exit code much simpler, and there is no longer any need for a mode (debug or normal) on it.

Fix a missing live register when breaking at ARM keyed load.

57769489d5 First phase of migration to new indexed property query callbacks. 
Eventually indexed property query callbacks will return attributes
(as an integer) or an empty handle if property is not intercepted.

To gradually migrate to this new API, USE_NEW_QUERY_CALLBACK
macro would control if old or new style API is used.

So the migration plan is:

1) introduce new API which should be explictily enabled;
2) switch to new API defining USE_NEW_QUERY_CALLBACK before
include of <v8.h> (that would require changes to client code as well)
3) remove old API from v8
4) remove #define USE_NEW_QUERY_CALLBACK from clients.

c98ac6e82c Heap profiler: implement diffing of snapshots. 
To trace objects between snapshots, an external map of object tags is
maintained. After the first heap snapshot has been taken, the map is
updated by reporting object moves from the GC. If no snapshots were
taken, there is no overhead (except for flag checking).

I considered graph comparison algorithms that doesn't require using
object tags, but they are all of a high computational complexity, and
will still fail to detect object moves properly, even for trivial
cases, so using tags looks like unavoidable.

634fb9152c More precise break points and stepping when debugging 
Added support for more precise break points when debugging and stepping. To achieve that additional nop instructions are inserted where breaking would otherwise be impossible. The number of nop instructions inserted are sufficient to make place for patching with a call to a debug break code stub. On Intel that is 5 nop's for 32-bit and 13 for 64-bit. Om ARM 3 nop instructions (12 bytes) are required.

In order to avoid inserting nop's in to many places a simple ast checker have been added to check whether there are breakable code in a statement or expression. If it is possible to break in an expression no additional break enabeling code is inserted.

Added break locations to the true and false part of a conditional expression.

Added stepping tests to cover more constructs.

These changes are only in the full compiler.

Changed the default value for the option --debugger in teh d8 shell from true to false. The reason for this is that with --debugger turned on the full compiler will be used for all code in when running d8, which can be unexpeceted.

12f6306420 First phase of migration to new named property query callbacks. 
Eventually named property query callbacks will return attributes
(as an integer) or an empty handle if property is not intercepted.

To gradually migrate to this new API, USE_NEW_QUERY_CALLBACK
macro would control if old or new style API is used.

So the migration plan is:

1) introduce new API which should be explictily enabled;
2) switch to new API defining USE_NEW_QUERY_CALLBACK before
  include of <v8.h> (that would require changes to client code as well)
3) remove old API from v8
4) remove #define USE_NEW_QUERY_CALLBACK from clients.

ebba43f37a Make intercepted properties retrievable only by getter to be not enumerable. 
Currently if there is no query callback, V8 finds out intercepted properties'
attributes using getter: if getter returns not empty handle V8 treats
such a property as property with NONE attribues which means this property
is enumerable.

However, if there is no enumerator, this property cannot be enumerated.
Thus I think we should treat such properties as not enumerable.

Drawback of this approach is now one has to implement both query and enumerator
callbacks to implement enumerable intercepted properties.

3e88d0d2af Various refactorings in interceptor calling and loading. 
1) do not push receiver early---that simplifies tail call preparation
on ia32/x64 and renders special cleanup unnecessary;
2) do not do second map check if interceptor's and cached holder
are the same;
3) do not push/pop receiver if receiver and holder registers are the same
(means that receiver is interceptor's holder);
4) do batch pushes on arm;
5) minor cosmetic improvements.

22e4847fde ARM: Update the full compiler to handle all code 
The full compiler is now complete on ARM as well. The syntax checker is still used to determine whether to use it for top level code or not during normal execution. When debugging is enabled all code will be compiled with the full compiler.

This change removes the temporary flag --force-full-compiler and now the flag --always-full-compiler enables the full compiler for all code on all platforms.

This also fixes building on Intel platform without debugger support (ENABLE_DEBUGGER_SUPPORT not defined) and adds full check for the full compiler for lazily compiled code.

-- layout change for SharedFunctionInfo: integer fields are stored as smi on
arm, ia32 and rearranged on x64.
-- layout change for String: meaning of LSB bit is fliped (1 now means hash not

Currently one can only define accessors on object templates.  This patch
allows to create accessors on the fly.

These accessors could control access to elements as well.  This element
support is somewhat rudimentary and may require future work (for example,
we probably don't want to convert index into a string.)

Changing ScriptData API to serialize its internal representation to a
const char* array.

This decouples the API from the internal representation and avoids the need for
callers to serialize themselves.

As a side-effect, ScriptData::New() no longer assumes ownership of its input.
This shouldn't matter as typical usage patterns for the old API would have
required a copy prior to calling ScriptData::New().

209711201d IA32: Use the full compiler when debugging 
The full compiler will now be used for all code compiler when debugging is active. As the code generated by the full compiler is much simpler it will be easier to make debugging work better when using that code.

To ensure that all code debugged is from the full compiler all functions will have to be recompiled when starting debugging. Initialing debugging already turns off the code cache.

3d7ce8ac19 CPU profiler: add secure profiles by filtering out functions using security tokens. 
As several pages can run in a single V8 instance, it is possible to
have functions from different security contexts intermixed in a single
CPU profile.  To avoid exposing function names from one page to
another, filtering is introduced.

The basic idea is that instead of capturing return addresses from
stack, we're now capturing JSFunction addresses (as we anyway work
only with JS stack frames.)  Each JSFunction can reach out for
context's security token. When providing a profile to a page, the
profile is filtered using the security token of caller page. Any
functions with different security tokens are filtered out (yes, we
only do fast path check for now) and their ticks are attributed to
their parents.

r3995 (http://code.google.com/p/v8/source/detail?r=3995) introduce performance
regression for the case when arrat size is small (think new Array(4)).

It turns out that in those cases rep stos is slower than plain loop (apprently
due to ecx increment, but I didn't check this hypothesis.)  The next thing
to try could be direct jump into right place of long sequence of stos'es.

61085478c6 Report approximated duration in milliseconds for profile nodes. 
The simple formula "ms = ticks * sampler_interval" doesn't work,
because e.g. on Linux, the actual sampling rate can be 5 times
lower than the one set up in the code. To calculate actual sampling
rate, current time is periodically queried and processed along with
actual sampling ticks count.

This is to make possible enabling usage of the new profiling subsystem
in Chromium without much hassle. The idea is pretty simple: unless the
new profiling API is used, all works as usual, as soon as Chromium
starts to use the new API, it will work too.

4f5ff869d3 C++ profiles processor: align browser mode with the old implementation, sample VM state. 
In browser (DevTools) mode, only non-native JS code and callbacks are reported.
Also, added "(garbage collector)" entry which accumulates samples count in GC state.
Trying to display "(compiler)" and "(external)" only brings confusion,
because it ends up in displaying scripts code under "(compiler)" node, and DOM
event handlers under "(external)" node, which looks weird.

That shouldn't be the problem for paged spaces as objects in those

54f0a5b221 Expose debug context into the native code. This change is doing several things: 
1) Exposes Local<Context> v8::Debug::GetDebugContext().
Rationale: We can already get debugger context instance using various workarounds,
so exposing it explicitly in the API only makes things more clear.

2) Removes debugger.HasJavaScriptFrames() requirement for entering debugger context.
Rationale: Sometimes we'd like to call into debugger from the external native code.

3) Makes Debugger v8::Debug::Call execute on debugger context's global object.
Rationale: This is somewhat arguable, but temporary measure. We've agreed that we
should introduce a DebugAPI object that would expose necessary API in the debug-delay.
The problem is that it would take some time to define this API and it is not really
convenient to do that on the v8 land given the difference in v8 / host lifecycle.
The plan is to compose this API as a Debug.* wrapper outside v8 by means of exposing
debugger context's global object here, and once API settles down, upstream it to v8 and
start making Debug::Calls on this new DebugAPI object instead.

e5f27966dc Add fuzzing support for inline runtime functions 
The inline runtime functions are now included in the fuzzing of the natives. The chack for the expected number of arguments passed have been moved to the parser which will generate a syntax error if a runtime function (either C++ or inline) is called with a different number of arguments than expected.

ad9ea637be Don't externalize fresh strings. 
With the current API the embedder has to extrenalize a string each
time a string is encountered to avoid the cost of repeated character
copying/conversion. The issue here is that the externalization cost
itself is non-negligible (both in time and space) and should not be
paid for a rarely used string. This change is an attempt to predict a
string's usage frequency based on its freshness. A string is
considered fresh if it was recently allocated in the new space.

f40ecb18c3 Fix stack overflow in cctest/test-api/Threadin2 after r3613. 
r3613 started wrapping all builtins in extra call in debug mode so it
became easier to cause stack overflow especially in 64-bit build.

5fe8bd9919 Fix 64-bit build on Windows and Visual Studio project files 
64-bit version now builds on Windows again in both release and debug mode.

The Visual Studio project files have been updated so that all three configurations work (32-bit, 64-bit and 32-bit with ARM simulator). They all convert from Visual Studio 2005 to Visual Studio 2008.

90045ddd5e Another step on the way to context snapshots. We can now refer to 
objects in the startup heap from a partial snapshot.  This happens
through the partial snapshot cache.  A startup snapshot and a
partial snapshot are created together so that the startup snapshot
contains the partial snapshot cache entries needed.

cf78ed05ee Don't pass the "at start" parameter to native RegExp 
As the start index is already passed it is easy to calculate the "at start" boolean in generated code. Also as direct entry has been implemented this needs to be done in generated code anyway, and therefore might as well be moved to the generated code for RegExp. The "at start" value is now calcualted as a local variable on the native RegExp frame based on the value of the start index argument.

The x64 version have been tested on both Linux and 64-bit Windows Vista.

For ARM I have tested cctest/test-regexp on ARM hardware, but the rest of the tests have only been run on the ARM simulator.

40fd97c87d A follow-up to fix 553: really report function object moves. 
As an afterthought, I realized that I put function objects moves
reporting into a method that deals with only code object moves.  I've
looked up that function objects are allocated in old pointer space and
new space, so I moved logging to the corresponding VM methods.

999e3fca90 Fix issue 553: function frame is skipped in profile when compare stub is called. 
The problem appeared due to a fact that stubs doesn't create a stack
frame, reusing the stack frame of the caller function. When building
stack traces, the current function is retrieved from PC, and its
callees are retrieved by traversing the stack backwards. Thus, for
stubs, the stub itself was discovered via PC, and then stub's caller's
caller was retrieved from stack.

To fix this problem, a pointer to JSFunction object is now captured
from the topmost stack frame, and is saved into stack trace log
record. Then a simple heuristics is applied whether a referred
function should be added to decoded stack, or not, to avoid reporting
the same function twice (from PC and from the pointer.)

d587851d7f Fix map compact implementation. 
Always invoke HeapObjectIterator::has_next() before invoking HeapObjectIterator::next().
This is necessary as ::has_next() has an important side-effect of going to the next
page when current page is exhausted.

And to find if pointers are encodable use more precise data---top of map space, not a number
of pages, as pages might stay in map space due to chunking.
