In addition, move the `--help` and `--v8-help` processing out of `StartNodeWithLoopAndArgs()` and process them earlier - right after `InitializeNodeWithArgs()`, similar to how they are handled in the legacy `Init()`.

2019-03-05src: use object to pass `Environment` to functionsAnna Henningsen
Use a `v8::Object` with an internal field, rather than a `v8::External`. On a `GetReturnValue().Set(Environment::GetCurrent(args) == nullptr)` noop function, this benchmarks as a ~60 % speedup, as calls to `obj->GetAlignedPointerFromInternalField()` can be inlined and the field is stored with one level of indirection less. This also makes breaking up some pieces of the `Environment` class into per-native-binding data easier, if we want to pursue that path in the future.

2019-01-30process: split execution into main scriptsJoyee Cheung
This patch splits the execution mode selection from the environment setup in `lib/internal/bootstrap/node.js`, and split the entry point of different execution mode into main scripts under `lib/internal/main`: - `check_syntax.js`: used when `-c`/`--check` which only checks the syntax of the input instead of executing it. - `eval_stdin.js`: used when `-e` is passed without value and stdin is not a TTY (e.g. something is piped). - `eval_string`: used when `-e` is passed along with a string argument - `inspect.js`: for `node inspect`/`node debug` - `print_bash_completion.js`: for `--completion-bash` - `print_help.js`: for `--help` - `prof_process.js`: for `--prof-process` - `repl.js`: for the REPL - `run_main_module.js`: used when a main module is passed - `run_third_party_main.js`: for the legacy `_third_party_main.js` support - `worker_thread.js`: for workers This makes the entry points easier to navigate and paves the way for customized v8 snapshots (that do not need to deserialize execution mode setup) and better embedder APIs. As an example, after this patch, for the most common case where Node.js executes a user module as an entry point, it essentially goes through: - `lib/internal/per_context.js` to setup the v8 Context (which is also run when setting up contexts for the `vm` module) - `lib/internal/bootstrap/loaders.js` to set up internal binding and builtin module loaders (that are separate from the loaders accessible in the user land). - `lib/internal/bootstrap/node.js`: to set up the rest of the environment, including various globals and the process object - `lib/internal/main/run_main_module.js`: which is selected from C++ to prepare execution of the user module. This patch also removes `NativeModuleLoader::CompileAndCall` and exposes `NativeModuleLoader::LookupAndCompile` directly so that we can handle syntax errors and runtime errors of bootstrap scripts differently.

Instead of using a shared pointer of the entire debug option set, pass the parsed debug option to inspector classes by value because they are set once the CLI argument parsing is done.

The port of the shared HostPort is 9229 by default and can be specified as 0 initially but will be set to the actual port of the server once it starts listening. This makes the shared state clearer and makes it possible to use `require('internal/options')` in JS land to query the CLI options instead of using `process._breakFirstLine` and other underscored properties of `process` since we are now certain that these values should not be altered once the parsing is done and can be passed around in copies without locks.

2018-11-20src: use STL containers instead of v8 values for static module dataJoyee Cheung
Instead of putting the source code and the cache in v8::Objects, put them in per-process std::maps. This has the following benefits: - It's slightly lighter in weight compared to storing things on the v8 heap. Also it may be slightly faster since the preivous v8::Object is already in dictionary mode - though the difference is very small given the number of native modules is limited. - The source and code cache generation templates are now much simpler since they just initialize static arrays and manipulate STL constructs. - The static native module data can be accessed independently of any Environment or Isolate, and it's easy to look them up from the C++'s side. - It's now impossible to mutate the source code used to compile native modules from the JS land since it's completely separate from the v8 heap. We can still get the constant strings from process.binding('natives') but that's all. A few drive-by fixes: - Remove DecorateErrorStack in LookupAndCompile - We don't need to capture the exception to decorate when we encounter errors during native module compilation, as those errors should be syntax errors and v8 is able to decorate them well. We use CompileFunctionInContext so there is no need to worry about wrappers either. - The code cache could be rejected when node is started with v8 flags. Instead of aborting in that case, simply keep a record in the native_module_without_cache set. - Refactor js2c.py a bit, reduce code duplication and inline Render() to make the one-byte/two-byte special treatment easier to read.
