      [inspector] support for nested scheduled breaks · 56bf7dbd
      kozyatinskiy authored 
      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.

      [inspector] Expose GetPossibleBreakpoints for wasm · c6663ef1
      clemensh authored 
      and add an inspector test for it. Also test that a breakpoint can be
set on each reported position, and that it is also hit during
execution.
This CL also fixes two little things which were uncovered by the new
test.

      [inspector] implemented blackboxing inside v8 · ac50c79a
      kozyatinskiy authored 
      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.

Current state and proposed changes for blackboxing: https://docs.google.com/document/d/1hnzaXPAN8_QC5ENxIgxgMNDbXLraM_OXT73rAyijTF8/edit?usp=sharing

      [inspector] Introduce debug::WasmScript · 12cdb31b
      clemensh authored 
      *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).

      [inspector] Split off interface-types.h · f5fb2da6
      clemensh authored 
      This CL adds a new header src/debug/interface-types.h, moves the
definition of Location from the debug-interface.h to this new header,
and adds a new definition for the WasmDisassembly types.
This allows to use the types in other implementation files or headers
without having to include the entire debug-interface.h, reducing build
dependencies and compile time (especially for incremental builds).

The WasmDisassembly type replaces the old
std::pair<std::string, std::vector<std::tuple<...>>>, which was a bit
hard to unravel.

      [inspector] Introduce translation of wasm frames · d4a42a5f
      clemensh authored 
      This allows to show wasm source (disassembled wasm code) in DevTools.
See design doc for details.

More tests for the disassembly will have to follow. Also, the text
format (generated by V8) will be changed.

      [inspector] Change ScriptBreakpoint to include scriptId · 764371bc
      clemensh authored 
      The ScriptBreakpoint struct was before just holding line, column and
condition. It now additionally holds the scriptId.
This encapsulates information nicer, and allows for easier translation
of wasm locations, since one struct now holds all information needed
for the translation.

      [debug-wrapper] Further extend the debug wrapper · b06c4ce5
      jgruber authored 
      This CL further extends the debug wrapper, migrates around 60 tests, and
removes a few tests that use functionality we will not support anymore.

In more detail:

* Removed tests that use:
  * enable/disable individual breakpoints
  * invocationText()
  * the ScriptCollected event
  * showBreakPoints
  * evalFromScript (and similar)
  * mirror.constructedBy and mirror.referencedBy
  * event_data.promise()
* Some frame.evaluate uses were adapted since due to differences between
  remote objects (inspector) and mirrors. For instance, exceptions are
  currently not recreated exactly, since the inspector protocol does not
  give us the stack and message separately. Other objects (such as
  'this' in debug-evaluate-receiver-before-super) need to be explicitly
  converted to a string before the test works correctly.
* Ensure that inspector stores the script before sending ScriptParsed and
  ScriptFailedToParse events in order to be able to use the script from
  within those events.
* Better remote object reconstruction (e.g. for undefined and arrays).
* New functionality in wrapper:
  * debuggerFlags().breakPointsActive.setValue()
  * scripts()
  * execState.setVariableValue()
  * execState.scopeObject().value()
  * execState.scopeObject().property()
  * execState.frame().allScopes()
  * eventData.exception()
  * eventData.script()
  * setBreakPointsActive()

      [inspector] Fix and refactor String16 · c9c6c1a3
      clemensh authored 
      This CL defines move semantics for String16, and fixes issues with the
hash code not being set correctly on swap or copy.
It also extends the interface by a few handy templates.
All this functionality will be used for the wasm translations, where
String16s are often concatenated and used as keys in hash tables.
