8e17c151d3 [coverage] Reduce the number of reported ranges
This CL adds a few transformations that clean up the set of reported
source ranges. Duplicates, empty, and uncovered ranges are removed, and
nested/consecutive ranges are merged if possible.

07752032e6 [wasm] Decode local names for debugging
When providing scope information (containing the value of local
variables of live stack frames), decode the local variable names of all
functions in a wasm module and store this in the WasmDebugInfo
structure.
Use these names to actually name the reported locals, instead of using
the default names "param#<d>" and "local#<d>". These names are only used
as fallbacks for locals which were not assigned a name.

8d921ca7f3 [turbofan] Remove --turbo shorthand for --turbo-filter.
This removes the --turbo flag and solely relies on the filter pattern
provided via --turbo-filter when deciding whether to use TurboFan. Note
that disabling optimization wholesale can still be done with --no-opt,
which should be used in favor of --no-turbo everywhere.

Also note that this contains semantic changes to the TurboFan activation
criteria. We respect the filter pattern more stringently and no longer
activate TurboFan just because the source contains patterns forcing use
of Ignition via {AstNumberingVisitor::DisableFullCodegenAndCrankshaft}.

1541f422a7 [coverage] Expose block coverage through inspector
This piggy-backs on top of existing precise and best-effort coverage to expose
block coverage through the inspector protocol.

Coverage collection now implicitly reports block-granularity coverage when
available.  A new 'isBlockCoverage' property on Inspector's FunctionCoverage
type specifies the granularity of reported coverage.

For now, only count-based block coverage is supported, but binary block
coverage should follow soon.

Support is still gated behind the --block-coverage flag.

701d79d08a [inspector] introduced console.context
console.context(name:string) method returns console instance, this console instance fully implements console interface (including fact that any method can be called without console as receiver).
Protocol.Runtime.consoleAPICalled notification contains additional context:string field:
- "anonymous#unique-id" for any method call on unnamed console context,
- "name#unique-id" for any method call on named console context.

console.count and console.timeEnd have context as a scope.
console.clear clear all messages regardless on what context instance it was called.

console calls is ~10% slower with this CL since we need to store and then fetch console_context_id and console_context_name from function object.
We recently (in April) made console calls twice faster so 10% doesn't sound critical and existing of console.log call in hot code is problem by itself.

  without receiving 'paused' notification;
- setBreakpointsActive flag is global affecting all sessions and context groups;
- max async call stack depth is global, and should be per context group.

And we additionally have a lot of other statement locations because of do scope.

Let's move async debugging closer to sync debugging and introduce only one break location for await - before awaited function call.

 - removed redundant break location for expressions like: let { x, y } = { x: 1, y: 2}.

a957b0f424 Make non-Module generators only context allocate parameters.
In particular, local variables should be allocated on stack (in bytecode register), and stored/loaded to the generator object on generator suspend/resume.

The CL is based on @adamk's change to scoping/parsers (https://chromium-review.googlesource.com/c/498538/), I only made the debugger cope with this change.

I should note that the CL changes the scope type of suspended generators from ScopeType.Closure to ScopeType.Local. In the future we might want to introduce ScopeType.SuspendedGenerator to make the distinction explicit.

Some of the changes in the tests have been made because the debugger functions do not return scopes of closed generators anymore. Generators should be allowed to throw away their internal state when they finish.

fb78710c06 [inspector] removed call break location from for-of loop
There are two break locations at the same source location by desugaring:
- call iterator.next,
- before variable assignment.

Additionally location for for..of loops is moved from before "of" to before each variable expression.

We should not report first implicit call to avoid user confusion. User still able to go into .next function with both scenarios:
- when this call is reached by stepOver or stepInto from previous line,
- when this call is reached because of breakpoint at current line.

cb7dd0a911 Replace sanitizers:deps with exe_and_shlib_deps (v8)
All targets (at least on sanitizer builds) unconditionally depend
on //build/config/sanitizers:deps.

It is necessary for bug 593874 that all targets now also depend
on //buildtools/third_party/libc++:libcxx_proxy.  This requires
adding a new "global dependency": //build/config:exe_and_shlib_deps.

This CL updates references to sanitizers:deps to instead refer to
//build/config:exe_and_shlib_deps.

5dc2d6f6c5 Reland: [ignition] Be smarter about register allocation in VisitSuspend
Split BytecodeGenerator::VisitSuspend into two pieces, one for
building the suspension code and one for resumption (these
are split into separate Build methods for convenience).
Each gets its own RegisterAllocationScope, which allows us to
reduce the register file size of the empty generator by 1.

For consistency, rename VisitGeneratorPrologue() to
BuildGeneratorPrologue() to match the names of the two
newly-created methods.

This relands the patch originally committed in
98927ea51b, as the test failure
due to that change was a code flushing bug. Code flushing was
disabled in de4a4095cf.

c6540ab1b7 [es6] don't use do-expressions to desugar ES6 classes
Removes the do-expression wrapping, modifies BytecodeGenerator change
to enter a class literal's block scope if needed.

This does not solve the actual bug in v8:6322, but helps mitigate it in
simple cases. The bug is caused by BytecodeGenerator not allocating a
large enough array of context registers to hold its entire stack,
allowing non-context registers to be overwritten during PushContext and
PopContext bytecodes.

Nevertheless, I like the idea of not depending on do-expressions when
possible, so I think it's worth doing anyways.

f2bd913cd4 [inspector] better stacks for promises
- we should always set creation async stack if it's available regardless existing of current parent async stack,
- we should cleanup parent link iff there is no creation and schedule async stack for parent.

Let's consider example: Promise.resolve().then(x => x).then(x => x), there is three promises which will call following instrumentation:
1) created #1 (Promise.resolve()) - collected stack #1
2) scheduled #1 - collected stack #2
3) created #2 with #1 as parent (first .then) - collected stack #3
4) created #3 with #2 as parent (first .then) - collected stack #4
5) started #2 - use stack #2 as scheduled
6) scheduled #2 - collected stack #6
7) finished #2
8) started #3 - use stack #6 as scheduled
9) scheduled #3 - collected stack #7
10) finished #3

If we collect stacks between step 4 and 5, it's possible to collect scheduled stack #2 but still have creation stack for #2 - stack #3 - so we always need to add creation event if scheduled is collected.

If we collect stacks between created and scheduled we should not remove parent link even if parent was not scheduled yet.

3. Updates testrunner/local/variants.py and

189ffd9460 [inspector] removed kDebugPromiseCollected event
With recent CLs we always store maximum N async stack traces and when we reach limit we drop half of them.
Current promise collected event requires creating weak handle:
- it takes time,
- it consumes memory.
Since async task id distribution for promises is uniform (each new promise has last_async_task_id + 1 as an id) our hash map is good enough to handle any amount of async task ids, following time of executing 1 000 000 000 of lookups:
- for empty hash map: 1.45 seconds,
- for hash map with one entry: 14.95 seconds
- 1024 entries: 15.03 seconds
- 1024 * 1024 entries: 14.82 seconds
- 1024 * 1024 * 1024: 17.9 seconds

54271c21e2 [inspector] move console to builtins
What will we get:
- console would be included into snapshot and allow us to reduce time that we spent in contextCreated function (~5 times faster),
- it allows us to make further small improvement of console methods, e.g. we can implement super quick return from console.assert if first argument is true,
- console calls are ~ 15% faster.

Speculative revert. Seems to block the roll:

Might require changing a browser test first?

6e70425be1 [wasm] Provide scope information via inspector
This CL implements the proposed change to show information about
WebAssembly values and call frames via the inspector interface.
Each interpreted WebAssembly frame will have two scopes: A global scope
showing information about the memory (to be extended for globals), and
a local scope showing information about parameters, local variables, and
stack values.
Names of local variables will be added later.

1a73f73b3b [wasm] Implement extensible name section
The format of the name section changed recently. It now contains
subsections of different type (currently for function names or local
variable names).
This CL changes our internal wasm module builders (in JS and C++) to
emit this new format, and changes the decoder to understand it.
We currently only parse the function name section, and ignore names of
local variables. I will later extend this to parse local variable names
when needed for debugging.

908cd38123 [inspector] console get all information from inspector when needed
With this CL we don't need to store reference to InspectedContext inside of JavaScript console object and able to get all required information from callback data.
It allows us to implement console methods without taking in account how and where we create and store these methods:
- later we can move console object implementation to builtins..
- ..and install command line API methods smarter.

We only report 1 the first time we collect coverage data after the

Since we do not care about the accurate execution count, we can optimize
the function once it has been executed once.

Also change best effort coverage to be implicitly binary.

760c56bddf [inspector] changed a way of preserving stepping between tasks
Indisputable profit:
- correct break location in next task (see tests),
- stepOver with async await never lands in random code (see related test and issue),
- inspector doesn't store current stepping state in debugger agent and completely trust V8 - step to new inspector-V8 design (I will finish design doc soon).
- willExecuteScript and didExecuteScript instrumentation could be removed from code base - reduce probability of future errors.
- finally - less code,
- stepping implementation in V8 makes another step to follow our stepping strategy (stepOut should do stepInto and break when exit current frame) (another one one page design doc based on @aandrey comment is coming),
- knowledge about existing of context groups is still inspector-only.

Disputable part is related to super rare scenario when in single isolate we have more then one context group id with enabled debugger agent:
- if one agent request break in own context (stepping, pause, e.t.c.) then we ignore all breaks in another agent. From one hand it looks like good: user clicks stepInto and they don't expect that execution could be paused by another instance of DevTools in unobservable from current DevTools way (second DevTools will get paused notification and run nested message loop). From another hand we shouldn't ignore breakpoints or debugger statement never. In general, I think that proposed behavior is rathe feature then issue.
- and disadvantage, on attempt to break in non-target context group id we just call StepOut until reach target context group id, step out call could deoptimize code in non related to current debugger agent context. But break could happens only in case of debugger stmt or breakpoint - sound like minor issue. Ignoring break on exception sounds like real issue but by module of rareness of this case I think we can ignore this.

Implementation details:
- when debugger agent request break for any reason it passes target context group id to V8Debugger - last agent requesting break is preferred.
- when V8Debugger gets BreakProgramRequested notification from V8, it checks current context group id against target context group id, if they match then just process break as usual otherwise makes StepOut action,
- debug.cc at the end of microtask if last_scheduled_action is StepOut, schedules StepIn and will break on first instruction in next task.

e27d18c943 [debugger] tuned StepNext and StepOut at return position
Proposed behaviour:
- StepNext at return position go into next function call (no changes with current behavior, but implemented in v8::Debug instead of hack on inspector side);
- StepOut at return position go into next non-current function call.

We need this to have better stepping in cases with native functions, blackboxed functions and/or different embedder calls (e.g. event listeners).

New behavior could be illustrated with two examples (for more see stepping-with-natives-and-frameworks test):
- let's assume that we've blackboxed callAll function, this function just takes its arguments and call one after another:
var foo = () => 1;
callAll(foo, foo, () => 2);
If we break inside of first call of function foo. Then on..
..StepNext - we're able to reach second call of function foo,
..StepOut - we're able to reach () => 2 call.

- let's consider case with native function:
[1,2,3].map(x => x * 2)
If we break inside of first callback call, then with StepNext we can iterate through all calls of callback, with StepOut we go to next statement after .map call.

Implementation details:
- when we request break we schedule step-in function call for any step action at return position and for step-in at any position,
- when we request StepOut at return position - we mark current function as needed-to-be-ignored inside of PrepareStepIn(function) call,
- when we request StepOut at not return position - we set break at return position and ask debugger to just repeat last step action on next stepping-related break.

18c35e4958 Collect type profile for DevTools
Collect type information for JavaScript variables and display it

Design Doc: https://docs.google.com/a/google.com/document/d/1O1uepXZXBI6IwiawTrYC3ohhiNgzkyTdjn3R8ysbYgk/edit?usp=sharing

When debugging JavaScript, it’s helpful to know the type of
a variable, parameter, and return values. JavaScript is
dynamically typed, and for complex
source code it’s often hard to infer types. With type profiling, we
can provide type information to JavaScript developers.

This CL is a proof of concept. It collects type profile for
assignments and simply prints the types to stdout.

The output looks something like this:

#my_var1
  #Object
  #number
  #string
  #number
  #undefined
  #string
  #Object
  #Object

We use an extra slot in the feedback vector of assignments to
carry the list of types for that assignment. The extra slot is
only added when the flag --type-profile is given.

Missing work:
* Collect data for parameters and return values (currently only assignments).
* Remove duplicates from the list of collected types and use a common base class.
* Add line numbers or source position instead of the variable name.

6cf880f4b8 Collect type profile for DevTools
Collect type information for JavaScript variables and display it
in Chrome DevTools.
Design Doc: https://docs.google.com/a/google.com/document/d/1O1uepXZXBI6IwiawTrYC3ohhiNgzkyTdjn3R8ysbYgk/edit?usp=sharing

When debugging JavaScript, it’s helpful to know the type of
a variable, parameter, and return values. JavaScript is
dynamically typed, and for complex
source code it’s often hard to infer types. With type profiling, we
can provide type information to JavaScript developers.

This CL is a proof of concept. It collects type profile for
assignments and simply prints the types to stdout.

The output looks something like this:

#my_var1
  #Object
  #number
  #string
  #number
  #undefined
  #string
  #Object
  #Object

We use an extra slot in the feedback vector of assignments to
carry the list of types for that assignment. The extra slot is
only added when the flag --type-profile is given.

Missing work:
* Collect data for parameters and return values (currently only assignments).
* Remove duplicates from the list of collected types and use a common base class.
* Add line numbers or source position instead of the variable name.

f774d8c56f [Flags] Add negation implications for --turbo negative so --no-turbo works.
Once we enabled --turbo by default we need to turn all the implications
off with --no-turbo as well. Chrome sets flags in V8 using SetFlagFromString,
which enforces the implications each time it is called. Therefore, if --turbo
is enabled by default, and an unrelated flag is set, the turbo implications are
enabled but not later disabled if we set --no-turbo. To fix this, add negative
implications as well.

In current implementation we don't support nested scheduled break at all. If one break was scheduled inside another and second one doesn't produce actual break (execution was in blackboxed code or no JavaScript was executed) then second one will clear first scheduled break even if any not blackboxed JavaScript will be executed later.

Ambiguous break reason is added for the case when we have more then one scheduled reason. "auxData" in this case contains object with array of { reason: reason, auxData: auxData } objects for each reason in 'reasons' property.

foo2 (test.js:14:2)

-- Promise.resolve (test.js:28:14)--

cb545a8c0c [inspector] change target promise for kDebugWillHandle & kDebugDidHandle
- kDebugPromiseCreated(task, parent_task)
This event occurs when promise is created (PromiseHookType::Init). V8Debugger uses this event to maintain task -> parent task map.

- kDebugEnqueueAsyncFunction(task)
This event occurs when first internal promise for async function is created. V8Debugger collects stack trace at this point.

- kDebugEnqueuePromiseResolve(task),
This event occurs when Promise fulfills with resolved status. V8Debugger collects stack trace at this point.

- kDebugEnqueuePromiseReject(task),
This event occurs when Promise fulfills with rejected status. V8Debugger collects stack trace at this point.

- kDebugPromiseCollected,
This event occurs when Promise is collected and no other chained callbacks can be added. V8Debugger removes information about async task for this promise.

- kDebugWillHandle,
This event occurs when chained promise function (either resolve or reject handler) is called. V8Debugger installs parent promise's stack (based on task -> parent_task map) as current if available or current promise's scheduled stack otherwise.

- kDebugDidHandle,
This event occurs after chained promise function has finished. V8Debugger restores asynchronous call chain to previous one.

With this change all instrumentation calls are related to current promise (before WillHandle and DidHandle were related to next async task).

Before V8Debugger supported only the following:
- asyncTaskScheduled(task1)
- asyncTaskStarted(task1)
- asyncTaskFinished(task1)

Now V8Debugger supports the following:
- asyncTaskScheduled(parent_task)
..
- asyncTaskCreated(task, parent_task),
- asyncTaskStarted(task), uses parent_task scheduled stack
- asyncTaskScheduled(task)
- asyncTaskFinished(task)

Additionally: WillHandle and DidHandle were migrated to PromiseHook API.

ac50c79a3e [inspector] implemented blackboxing inside v8
V8 has internal mechanism to ignore steps and breaks inside internal scripts, in this CL it's reused for blackboxing implementation.
Advantages:
- much faster blackboxing implementation (before we at least wrap and collect current call stack for each step),
- get rid of StepFrame action and potential pause in blackboxed code after N StepFrame steps,
- simplification of debugger agent logic.
Disadvtanges:
- currently when user was paused in blackboxed code (e.g. on breakpoint) and then makes step action, debugger ignores blackboxed state of the script and allows to use step actions as usual - this behavior is regressed, we still able to support it on frontend side.

754736d26c [inspector] async stacks for Promise.then calls...
... which were done after the promise has been resolved.

Goal of this CL - change promise instrumentation to support better callbacks, chained after promise resolution and prepare instrumentation for adding new asyncTaskCreated instrumentation.

Instrumentation changes:
- asyncTaskScheduled(recurring) when promise is fulfilled or rejected,
- asyncTaskCancelled when promise is collected (since [1] we can be sure that promise will survive scheduled microtasks).

Minor changes:
- async task type in inspector <-> debugger API transferred by enum instead of string,
- Debug manages async task ids based on promise objects.

12cdb31b2f [inspector] Introduce debug::WasmScript
*and* report all "virtual" wasm scripts right when the wasm script is
registered at the inspector.

WasmScript is a subtype of Script, with the cast checking that it is
actually a wasm script.
This layout makes it quite easy to implement functionality that is only
available for wasm scripts, and allows to later directly use the
WasmCompiledModule instead of the i::Script for backing the
debug::WasmScript. We might also add virtual methods to
provide different implementations for GetSourcePosition, Source and
others.

DisassembleWasmFunction now also becomes a method of this class instead
of a static function on the DebugInterface.

The WasmTranslation now uses the new WasmScript type instead of the
Script wrapper, and also registers all virtual wasm scripts immediately
when the wasm script is made public to the inspector (when the wasm
module is created).

ae0e92219b Properly define v8_enable_inspector and its override in GN.
Instead of directly using v8_enable_inspector_override from
build_overrides/v8.gni in all the GN configs, set a v8_enable_inspector
variable based on v8_enable_inspector_override and use that everywhere.
This is the more common pattern seen in over projects, and reduces the
need to include //build_overrides/v8.gni in many files.

With this change, WebAssembly.Memory objects have backing stores allocated as an

GrowMemory is now implemented by changing the protection on the guard regions to

Guard pages are not enabled by default, but this change adds a flag and a test
variant to make sure we get test coverage on them.

32077e01fb [wasm] Allocate a single script per wasm module
Before, we allocated one script per function per instance, and each
script referenced the wasm instance and the function index. Now we only
allocate one script per compiled wasm module, so the script also only
references this WasmCompiledModule, which causes changes to many interfaces.

Instead of fixing the disassemble API only used via debug.js, I decided
to drop it for now. Some later CL will reintroduce it via
DebugInterface.

1cac34ed6b Fix detection of BUILTIN functions
In the asm.js to wasm pipeline, we generate an entry function with
BUILTIN code, but still attached to a TYPE_NORMAL script.
This fix avoids trying to set a breakpoint there, resulting in a crash
on DCHECK(shared->HasDebugInfo()).

Also add two inspector tests to track regressions.

d7a18896bd [inspector] enable inspector by default
To achieve this:
- fixed crash on windows - String16::fromInteger used "%zu" which doesn't support by VS2013 compiler, wrapped with ifdef else.
- fixed asan for d8 - unique_ptr on array has single element type.
- force Debugger.disable at the end of test.
