yurys@chromium.org	707fdd4c6a	Support idle time in CPU profiler ... This change provides an API for the embedder to tell CPU profiler if it is idle or busy with some task. This way we can discriminate between idle time and some native code execution.

mstarzinger@chromium.org	63defee477	First implementation of allocation elimination in Hydrogen. ... This change implements a simple data-flow analysis pass over captured objects to the existing escape analysis. It tracks the state of values in the Hydrogen graph through CapturedObject marker instructions that are used to construct an appropriate translation for the deoptimizer to be able to materialize these objects again. This can be considered a combination of scalar replacement of loads and stores on captured objects and sinking of unused allocations.

yangguo@chromium.org	8fb95efdda	Improve internal stringifcation for custom Error objects. ... If an developer attempts to "subclass" Error by running `MyError.prototype = new Error();`, then the internal v8::Message object that's produced and handed off to `window.onerror` handlers is poorly stringified as "[object Object]". This patch adjusts the stringification process for these objects to include not only native Error objects, but also objects that have Error in their prototype chain, and haven't overwritten Error.toString with some custom variant.

rossberg@chromium.org	92bd4d1f2d	I found this working on ... https://codereview.chromium.org/19541010/ The main problem is that if you called Object.getNotifier(obj) on an object, %SetObserved(object) would never get called on it, and thus it would be unobservable (new test added for this). Additionally, Runtime::SetObserved was asserting obj->IsJSObject() which would fail if called on a proxy. It just happens that our existing test always called getNotifier() before Object.observe on proxies, and thus we never previously attempted to transition the map of a proxy. Both issues are now fixed and properly tested.

loislo@chromium.org	d2c443b774	Extract hardcoded error strings into a single place and replace them with enum. ... I'd like to propagate bailout reason to cpu profiler. So I need to save it into heap object SharedFunctionInfo. But: 1) all bailout reason strings spread across all the sources. 2) they are native strings and if I convert them into String then I may have a performance issue. 3) one byte is enough for 184 bailout reasons. Otherwise we need 8 bytes for the pointer. Also I think it would be nice to have error strings collected in one place. In that case we will get additional benefits: It allows us to keep this set of messages under control. It gives us a chance to internationalize them. It slightly reduces the binary footprint.

yurys@chromium.org	97f8f91bb5	Fix call stack sampling for the case when native callback invokes JS function ... The SafeStackFrameIterator used by CPU profiler checked if Isolate::c_entry_fp is null and if it is not it would think that the control flow currently is in some native code. This assumption is wrong because the native code could have called a JS function but JSEntryStub would not reset c_entry_fp to NULL in that case. This CL adds a check in SafeStackFrameIterator::IsValidTop for the case when there is a JAVA_SCRIPT frame on top of EXIT frame. Also this CL changes ExternalCallbackScope behavior to provide access to the whole stack of the scope objects instead of only top one. This allowed to provide exact callback names for those EXIT frames where external callbacks are called. Without this change it was possible only for the top most native call.

This change fixes data race described in the bug by adding Acquire_Load to SamplingCircularQueue::StartDequeue and Acquire_Store to SamplingCircularQueue::Enqueue. Also the queue implementation imposed a constraint on the records it stored: the first AtomicWord in each record was a marker. For that purpose TickSampleEventRecord had filter field of type int. This approach is error prone, e.g. on x64 sizeof(AtomicWord) is 8 while sizeof(int) is 4. Moreover the queue needs such marker only at the beginning of chunk.

adamk@chromium.org	fab9f4e126	[Object.observe] Lazily allocate callbackInfo structure ... This patch allows callbacks to lazily allocate the InternalArray which is used to store pendingChangeRecords. This moves some of the expense of observation to the case where changes actually occurred. When there are no pendingChangeRecords, the callbackInfo structure is a number which is the callbacks priority. Whenever a changeRecord is enqueued to the callback, it "normalizes" to be an InternalArray with a priority property. Immediately before its changeRecords are delivered, it returns to its optimized state. --- Note: Naming confusion resolved: This patch corrects some naming confusion in object-observe.js. Previously, we used the terms "callback" and "observer" to mean roughly the same thing, and overloaded the term "observer" to be both the callback itself and the *registration* on a object to observe (which now includes an accept map). This patch resolves this confusion: "object" (objectInfo, objectInfoMap): This refers to the observed object and its structures "callback" (callbackInfo, callbackInfoMap): This refers to the callback to whom change records may be delivered "observer" (objectInfo.changeObservers): This refers to a registration to observe a given object by a given callback with the specified accept list. --- R=rossberg@chromium.org Review URL: https://codereview.chromium.org/19132002 Patch from Rafael Weinstein <rafaelw@chromium.org>. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@15682 ce2b1a6d-e550-0410-aec6-3dcde31c8c00	2013-07-15 22:16:30 +00:00

mvstanton@chromium.org	c1e19bfc35	Bugfix: The general array constructor stub did not handle the case ... properly when it is called with a function pointer in the type cell, instead assuming that an AllocationSite object should be present. The case where this can happen is if the cell is uninitialized, then the first constructor call made is to the Array function of a different context. In that case, we'll store the function pointer in the cell, and then go ahead and call the array constructor stub too. The bug is fixed by checking for the AllocationSite object map. If not found, the constructor stub goes forward with a default ElementsKind, just as in several other cases. A test in allocation-site-info.js was beefed up to make sure the state chain described above is traversed.

yurys@chromium.org	44dfaa2a1e	Fix test-cpu-profiler/FunctionCallSample flakiness under GC stress testing ... The test flakes on "V8 GC Stress" bots and the sample looks like this: [Top down]: 90 0 (root) [-1] #0 1 1 1 (program) [-1] #0 2 89 89 (garbage collector) [-1] #0 3 which means that almost all samples are inside GC and we have no |start| node in the collected profile. Running the test with different combinations of --gc-interval=500 and --stress-compaction flags gives the results quoted below. They don't give a ground to require |start| node presense in the profile when doing GC stress testing. So this change makes the |start| node optional in the collected profile if GC stress testing is on. $ ./out/ia32.debug/cctest --gc-interval=500 --stress-compaction --trace-gc test-cpu-profiler/FunctionCallSample [10291] 76 ms: Mark-sweep 0.5 (17.8) -> 0.4 (17.8) MB, 49.5 ms (+ 0.2 ms in 1 steps since start of marking, biggest step 0.2 ms) [StackGuard GC request] [GC in old space requested].

yurys@chromium.org	4c5508b42f	Correctly report callstack when current function is FunctionCall builtin ... When current function is FunctionCall builtin we have no reliable way to determine its caller function (in many cases the top of the sampled stack contains address of the caller but sometimes it does not). Instead of dropping the sample or its two top frames we simply mark the caller frame as '(unresolved function)'. It seems like a better approach that dropping whole sample as knowing the top function and the rest of the stack the user should be able to figure out what the caller was.

yurys@chromium.org	91dc6dd632	Correctly report callstack when current function is FunctionCall builtin ... When current function is FunctionCall builtin we have no reliable way to determine its caller function (in many cases the top of the sampled stack contains address of the caller but sometimes it does not). Instead of dropping the sample or its two top frames we simply mark the caller frame as '(unresolved function)'. It seems like a better approach that dropping whole sample as knowing the top function and the rest of the stack the user should be able to figure out what the caller was. This change adds builtin id to CodeEntry objects. It will be used later to add similar top frame analysis for FunctionApply and probably other builtins.

yurys@chromium.org	0ac0edb707	Test that profiler is stopped when isolate is being disposed ... The only way to get v8::CpuProfiler instance in the V8 public API is to call v8::Iolate::GetCpuProfiler(). The method will return NULL if the isolate has not been initialized yet or has been torn down already. It is the client's reponsibility to make sure that CPU profiling has been stopped before disposing of the isolate. This CL adds a test for this and several ASSRTS enforcing that assumptions. This allowed to be sure that heap is always setup when CPU profiling is being started. Based on that the number of places where already compiled functions are reported to the profiler event processor boils down to the single place (CpuProfiler::StartProcessorIfNotStarted). I'm going to rely on this assumption in further changes.

This change SafeStackFrameIterator always iterate only frames and removes checks corresponding to the handlers iteration. The problem described in the bug occurred because of a false assumption in SafeStackFrameIterator that if Isolate::c_entry_fp is not NULL then the top frame on the stack is always a C++ frame. It is false because we may have entered JS code again, in which case JS_ENTRY code stub generated by JSEntryStub::GenerateBody() will save current c_entry_fp value but not reset it to NULL and after that it will create ENTRY stack frame and JS_ENTRY handler on the stack and put the latter into Isolate::handler(top). This means that if we start iterating from c_entry_fp frame and try to compare the frame's sp with Isolate::handler()->address() it will turn out that frame->sp() > handler->address() and the condition in SafeStackFrameIterator::CanIterateHandles is not held.
