src: add --heapsnapshot-near-heap-limit option

2020-10-21T19:41:11+00:00

This patch adds a --heapsnapshot-near-heap-limit CLI option
that takes heap snapshots when the V8 heap is approaching
the heap size limit. It will try to write the snapshots
to disk before the program crashes due to OOM.

src: fix incorrect SIGSEGV handling in NODE_USE_V8_WASM_TRAP_HANDLER

2020-09-26T10:30:39+00:00

Pass SA_SIGINFO to sa_flags so the TrapWebAssemblyOrContinue is treated
as sa_sigaction, not sa_handler, otherwise siginfo_t* info contains
some garbage

perf_hooks: add idleTime and event loop util

2020-08-29T14:02:31+00:00

Use uv_metrics_idle_time() to return a high resolution millisecond timer
of the amount of time the event loop has been idle since it was
initialized.

Include performance.eventLoopUtilization() API to handle the math of
calculating the idle and active times. This has been added to prevent
accidental miscalculations of the event loop utilization. Such as not
taking into consideration offsetting nodeTiming.loopStart or timing
differences when being called from a Worker thread.

module: unflag Top-Level Await

2020-08-03T18:27:28+00:00

This unflags Top-Level await so it can be used by default in the module
goal. This is accomplished by manually setting the
--harmony-top-level-await flag. We are allowing this as a one of
approval based on circumstances. It is not a precedent that future
harmony features will be manually enabled.

src: make code cache test work with snapshots

2020-07-18T03:23:13+00:00

Keep track of snapshotted modules in JS land, and move
bootstrap switches into StartExecution() so that
they are not included into part of the environment-independent
bootstrap process.

src: add an ExternalReferenceRegistry class

2020-07-18T03:02:58+00:00

Add an ExternalReferenceRegistry class for registering static
external references.

To register the external JS to C++ references created in a binding
(e.g. when a FunctionTemplate is created):

- Add the binding name (same as the id used for `internalBinding()`
  and `NODE_MODULE_CONTEXT_AWARE_INTERNAL`) to
  `EXTERNAL_REFERENCE_BINDING_LIST` in `src/node_external_reference.h`.
- In the file where the binding is implemented, create a registration
  function to register the static C++ references (e.g. the C++
  functions in `v8::FunctionCallback` associated with the function
  templates), like this:

  ```c++
  void RegisterExternalReferences(
          ExternalReferenceRegistry* registry) {
    registry->Register(cpp_func_1);
  }
  ```
- At the end of the file where `NODE_MODULE_CONTEXT_AWARE_INTERNAL` is
  also usually called, register the registration function with

  ```
  NODE_MODULE_EXTERNAL_REFERENCE(binding_name,
                                 RegisterExternalReferences);
  ```
