vm: add bindings for v8::CompileFunctionInContext #21571

@ryzokuken ryzokuken commented Jun 28, 2018

Adds a method compileFunction to the vm module, which serves as a
binding for v8::CompileFunctionInContext with appropriate args for
specifying the details, and provide params for the wrapper.

Eventually, we would be changing Module._compile to use this internally
over the standard Module.wrap

That could be rad, but I'm supposing that most people would just be expecting the function or would disable the cache and then we'll be returning { function }, which doesn't look super good?

Like mentioned previously, let's not have this at all, and expose ScriptCompiler::CreateCodeCacheForFunction in a separate binding like we already do for ScriptCompiler::CreateCodeCache.

No idea, my guess is that we set them to 0 for like... 99% cases, but I put them in just for parity with ContextifyScript::New.

well in ContextifyScript the entire source can be offset for dealing with source positions in html bodies and such. if they don't do anything here it would be best to remove them. (easy test is offset by a bunch and make the body have a syntax error, then read the column offset in the stack)

I think this could be useful.

One way to test this is to throw an exception ans check whether the exception position is affected by the offsets.

@ryzokuken If you have a CHECK() in your native code, you should make sure that that check cannot be reached from userland as well as that is possible (so, yes)

Should we discuss the option of splitting code caching into a separate function entirely? There is no reason to bundle it with compilation aside from symmetry with ContextifyScript::New, where the code caching option is going to be deprecated.

Cool, will add the checks in JS-Land for all options as well, in that case.

Definitely. I think that's what we're going towards for New anyway, right?

Could you elaborate? It is checked if cachedData is an Object or not, but it's not checked in it's a Uint8Array. Do you propose I add checking for the exact type? I think I should do that, but couldn't find instances of the same in the codebase.

Yes.

Because the entire (or at least most of) codebase is now free of Uint8Array-only functions. You could use isUint8Array() in internal/util/types.js for this purpose.

That's exactly what @targos suggested, but then I'm also using the same object for type-checking. Would transition to a hard-coded types approach instead of the inferred approach as used here, it sounds better in this case anyway.

This hasn't been fixed yet. Note, you don't need to support all types of ArrayBufferView to use Buffer methods. In fact you can do a direct switch of data + cached_data_buf->ByteOffset() by Buffer::Data(cached_data_buf) and cached_data_buf->ByteLength() by Buffer::Length(cached_data_buf).

I realized that, and had been planning to change these in both CompileFunction and Script::New in a quick subsequent PR. I could make one right now, if you'd like.

Or would you still prefer that I make the switch in this one and just change Script::New in the other PR?

Yeah it throws for non-objects, but returns a boolean for objects. Check out the implementation for _isContext:

That's the thing: it throws for null as well as non-objects, and I'm testing for null, which complicates things. Isn't null an object too? It shouldn't fail the CHECK, right?

We've generally tried to avoid using forEach within core functions because it's an order of magnitude slower than a regular for-loop. Even if this is not expected to be a hot function, I think I'd rather see this as a regular for-loop.

if we're taking the performance approach, forEach has actually become faster in the common case than a for loop (in V8 anyway).

Whatever the outcome of this discussion, please let’s not hold up the PR over this – this isn’t hot code (or at least the cost of actual parsing + compilation is likely going to overshadow any choice of this kind), so I think it’s fine to go with whatever the PR author considers most readable.

  * Added two new methods: `os.getPriority` and `os.setPriority`, allowing to
    manipulate the scheduling priority of processes. #22407
* process:
  * Added `process.allowedNodeEnvironmentFlags`. This object can be used to
    programmatically validate and list flags that are allowed in the
    `NODE_OPTIONS` environment variable. #19335
* src:
  * Deprecated option variables in public C++ API. #22515
  * Refactored options parsing. #22392
* vm:
  * Added `vm.compileFunction`, a method to create new JavaScript functions from
    a source body, with options similar to those of the other `vm` methods. #21571
* Added new collaborators:
  * [lundibundi](https://github.com/lundibundi) - Denys Otrishko

Notable changes:

* child_process:
  * `TypedArray` and `DataView` values are now accepted as input by
    `execFileSync` and `spawnSync`. #22409
* coverage:
  * Native V8 code coverage information can now be output to disk by setting the
    environment variable `NODE_V8_COVERAGE` to a directory. #22527
* deps:
  * The bundled npm was upgraded to version 6.4.1. #22591
    * Changelogs:
      [6.3.0-next.0](https://github.com/npm/cli/releases/tag/v6.3.0-next.0)
      [6.3.0](https://github.com/npm/cli/releases/tag/v6.3.0)
      [6.4.0](https://github.com/npm/cli/releases/tag/v6.4.0)
      [6.4.1](https://github.com/npm/cli/releases/tag/v6.4.1)
* fs:
  * The methods `fs.read`, `fs.readSync`, `fs.write`, `fs.writeSync`,
    `fs.writeFile` and `fs.writeFileSync` now all accept `TypedArray` and
    `DataView` objects. #22150
  * A new boolean option, `withFileTypes`, can be passed to to `fs.readdir` and
    `fs.readdirSync`. If set to true, the methods return an array of directory
    entries. These are objects that can be used to determine the type of each
    entry and filter them based on that without calling `fs.stat`. #22020
* http2:
  * The `http2` module is no longer experimental. #22466
* os:
  * Added two new methods: `os.getPriority` and `os.setPriority`, allowing to
    manipulate the scheduling priority of processes. #22407

  * Added `process.allowedNodeEnvironmentFlags`. This object can be used to
    programmatically validate and list flags that are allowed in the
    `NODE_OPTIONS` environment variable. #19335
