A lot of different clients use console.debug as a message channel from
page to protocol client. console.debug is a little slow and not
designed for this use case.
This CL introduces new method: Runtime.installBinding. This method
installs binding function by given name on global object on each
inspected context including any context created later.
Binding function takes exactly one string argument. Each time when
binding function is called, Runtime.bindingCalled notification is
triggered and includes passed payload.
Binding function survives page reload and reinstalled right after
console object is setup. So installed binding can be used inside
script added by Page.addScriptToEvaluateOnNewDocument so client may do
something like:
Runtime.installBinding({name: 'send'});
Page.addScriptToEvaluateOnNewDocument({source: 'console.debug = send'});
.. navigate page ..
In microbenchmark this function is ~4.6 times faster then
console.debug.

New intstrumentation consists of:
- kAsyncFunctionSuspended when async function is suspended on await
(called on each await),
- kAsyncFunctionFinished when async function is finished.
Old instrumentation was based on reusing async function promise.
Using this promise produces couple side effects:
- for any promise instrumentation we first need to check if it is
special case for async function promise or not - it requires
expensive reading from promise object.
- we capture stack for async functions even if it does not contain
awaits.
- we do not properly cancel async task created for async function.
New intsrumntation resolved all these problems as well as provide
clear mapping between async task and generator which we can use later
to fetch scope information for async functions on pause.

With this CL we use interrupt for pause in two cases:
- when we process Debugger.pause on interruption,
- when we would like to break as soon as possible after OOM.
In all other cases, e.g. for async step into we use break
on function call by calling StepIn debugger action.
In mentioned cases we should not actually use interrupt as well:
- Debugger.pause in this case scheduled using interrupt and we
may just break right now without requesting another interrupt,
unfortunately blink side is not ready,
- we should use more reliable way to break right after near OOM
callback, otherwise we can get this callback, increase limit,
request break on next interrupt, before interrupt get another
huge memory allocation and crash.
There are couple advantages:
- we get much better break locations for async stepping
(see inspector tests expectations),
- we can remove DEBUG_BREAK interruption
(it should speedup blackboxing with async tasks, see
removed todo in debug.cc for details)
- it is required preparation step for async step out,

The embedder can get notification when V8 heap size approaches the heap limit
and can extend the heap limit if needed using
- v8::Isolate::AddNearHeapLimitCallback
- v8::Isolate::RemoveNearHeapLimitCallback
This generalizes the exiting v8::debug::SetOutOfMemoryCallback API.

Now, 'queryObjects' takes an optional 'objectGroup' argument,

This is important because each call produces a new Array, which

The debugger script implementation had its own way to write
uint32_t values to a string as hex values. This removes the
custom code and uses a shared implementation in String16Builder
instead.
The observable effect is that script hashes are now lower-case
and the character sequence is reversed for each 8-character
pair.

We already cleanup these scripts on frontend side. It is crucial to
cleanup them on backend side as well, since some web applications use
following logic: get some data from network, add this data to buffer,
try to parse buffer using JSON.parse. On each unsuccessfull JSON.parse
we get another scriptFailedToParse event.
Frontend logic of discarding scripts: https://goo.gl/FDtaWK
Some idea of smarter logic here: track what script ids are reported
using protocol and cleanup only script ids which reported not only as
part of scriptFailedToParse event.

Before this, only the [[ProxyHandler]] was set to null during revocation
of the Proxy through either the v8::Proxy::Revoke() or the
Proxy.revocable() API. To be consistent with the spec, the Proxy's
target is set to null as well. This change should not be observable
through JS, since the check for if the Proxy is revoked should always
use the handler. But the changed value is exposed through the public
v8::Proxy::GetTarget() API, which is used by the inspector API and
Node.js.
Also included is a much more comprehensive test for Inspector's support
for Proxy, which prior to this commit did not work as intended.

Old instrumentation was designed to collect promise creation stack and
promise scheduled stack together. In DevTools for last 6 months we
show only creation stack for promises. We got strong support from users
for new model. Now we can drop support for scheduled stacks and
simplify implementation.
New promise instrumentation is straightforward:
- we send kDebugPromiseThen when promise is created by .then call,
- we send kDebugPromiseCatch when promise is created by .catch call,
- we send kDebugWillHandle before chained callback and kDebugDidHandle
after chained callback,
- and we send separate kDebugAsyncFunctionPromiseCreated for internal
promise inside async await function.
Advantages:
- we reduce amount of captured stacks (we do not capture stack for
promise that constructed not by .then or .catch),
- we can consider async task related to .then and .catch as one shot
since chained callback is executed once,
- on V8 side we can implement required instrumentation using only
promise hooks,
Disadvantage:
- see await-promise test, sometimes scheduled stack was useful since we
add catch handler in native code,
Implementation details:
- on kInit promise hook we need to figure out why promise was created.
We analyze builtin functions until first user defined function on
current stack. If there is kAsyncFunctionPromiseCreate function then
we send kDebugAsyncFunctionPromiseCreated event. If there is
kPromiseThen or kPromiseCatch then only if this function is bottom
builtin function we send corresponded event to inspector. We need it
because Promise.all internally calls .then and in this case we have
Promise.all and Promise.then on stack at the same time and we do not
need to report this internally created promise to inspector.

It is preparation step for step-into-worker. There are few changes:
- added breakOnAsyncCall flag for Debugger.stepInto. When flag is set
and async task is scheduled before step-into finished, we pause
execution with additional Debugger.paused event. This event contains
additional scheduledAsyncTaskId field.
- added Debugger.pauseOnAsyncTask. This method will pause execution as
soon as given async task is started.
This mechanism is replacement for Debugger.scheduleStepIntoAsync which
can not be used between multiple targets.
As result we can split async task scheduling in one target and
requesting break for this async task running in another target.

Debugger.setBreakpointByUrl method provides capabilities to set

I considered other options such as replacing scriptId with something

JavaScript is a dynamically typed language. But most code is
written with fixed types in mind. When debugging JavaScript,
it is helpful to know the types of variables and parameters
at runtime. It is often hard to infer types for complex code.
Type profiling provides this information at runtime.
Node.js uses the inspector protocol. This CL allows Node.js users
to access and analyse type profile for via Node modules or the
in-procress api. Type Profile helps developers to analyze
their code for correctness and performance.
Design doc: https://docs.google.com/a/google.com/document/d/1O1uepXZXBI6IwiawTrYC3ohhiNgzkyTdjn3R8ysbYgk/edit?usp=sharing
Add `takeTypeProfile` to the inspector protocol. It returns a list
of TypeProfileForScripts, which in turn contains the type profile for
each function. We can use TypeProfile data to annotate JavaScript code.
Sample script with data from TypeProfile:
function f(/*Object, number, undefined*/a,
/*Array, number, null*/b,
/*boolean, Object, symbol*/c) {
return 'bye';
/*string*/};
f({}, [], true);
f(3, 2.3, {a: 42});
f(undefined, null, Symbol('hello'));/*string*/

There are a lot of opportunities how we can improve breakpoints (at least we can avoid some of linear lookups to speedup implementation) but I think that as first step we need to remove mirrors/debug.js APIs.
Drive by: debugger-script.js and usage of debugger context in inspector code base.

This CL moves us much closer to the point where we can remove debugger-script.js and usage of debugger context from inspector.
There are three main parts left:
- managing breakpoints,
- inspecting stack and scopes (this CL),
- LiveEdit.
In this CL I moved all stack/scope inspection to native. As side effect running debugger and inspector tests are 10-20% faster (it's significant since not all of tests requesting break).

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.

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.

- 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.

Currently, the external API (e.g. v8::Object::Get()) will enter the
context passed to it automatically. This is incorrect and causes some
trouble for Blink, so we want to change that.
It then becomes a potential problem to call the external API without
first entering a context, which the inspector code does in some
places. This patch aims to correct this.

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

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.
