assert,deps,repl: fix repl and assert not being able to handle language features properly #27400

BridgeAR · 2019-04-24T22:21:23Z

This adds a acorn plugins to properly handle stage-3 language features in the REPL and assert.

I stripped the plugins to the minimum and also removed a couple of files that we will not use to reduce our code overhead in core.

I had to change the require calls in the plugins to work properly with core but I guess that's expected.

The numeric separators are not yet supported by V8 but it should be supported by v7.5, so adding it now makes this feature available from the moment we include the new version.

There are a few more plugins for other language features: acorn-dynamic-import, acorn-import-meta and acorn-export-ns-from. These are all @nodejs/modules related and I am not sure if we should include these as well or not. I felt these are not suitable for us but I might be wrong?

We currently include the main acorn license file which states Copyright (C) 2012-2018 by various contributors (see AUTHORS). The plugin licenses are also MIT licenses but it states Copyright (C) 2017-2018 by Adrian Heine. I am not sure if the various contributors would be sufficient here, since this is a single person for these modules even though they are hosted in the acornjs organization.
If we have to pull in the other licenses, should I move the plugins out into another folder so that we use a single license for all plugins together (they are all written by the same person / have the same license) or should we include all licenses individually?

Fixes: #27391
Fixes: #25835

This adds bigint, class-fields, numeric-separators, static-class features, private class methods and fields as dependency. That way it's possible to use these in combination with acorn to parse these language features. This also removes a couple of files that were not necessary for Node.js to reduce the code base.

This adds new language features to acorn. Otherwise BigInt and other input would not be parsed correct and would not result in nice error messages when using simple assert.

This adds stage-3 language features to acorn so that it's possible to parse these features when using top level await in the REPL.

@BridgeAR Take a look at nodejs/ecmascript-modules#69. I was working around the lack of import() support in Acorn for that PR, so having such support would be nice (but not required).

BridgeAR · 2019-04-24T22:34:12Z

@GeoffreyBooth I suggest that you add the necessary Plugin to your PR but I am not sure if it's necessary for assert or the REPL to have support for this.

@nodejs/tsc PTAL about the licensing questions (see #27400 (comment)).

@nodejs/assert @nodejs/repl PTAL

targos · 2019-04-26T16:42:17Z

My suggestion regarding the license:

Move all acorn plugins to a new directory: deps/acorn-plugins
targos@6d8e444

lib/assert.js

BridgeAR · 2019-04-26T17:07:50Z

@targos I incorporated your suggestion.

Notable changes: * deps: * Updated llhttp to 1.1.3. This fixes a bug that made Node.js' HTTP parser refuse any request URL that contained the "|" (vertical bar) character. #27595 * tls: * Added an `enableTrace()` method to `TLSSocket` and an `enableTrace` option to `tls.createServer()`. When enabled, TSL packet trace information is written to `stderr`. This can be used to debug TLS connection problems. #27497 #27376 * cli: * Added a `--trace-tls` command-line flag that enables tracing of TLS connections without the need to modify existing application code. #27497 * Added a `--cpu-prof-interval` command-line flag. It can be used to specify the sampling interval for the CPU profiles generated by `--cpu-prof`. #27535 * module: * Added the `createRequire()` method. It allows to create a require function from a file URL object, a file URL string or an absolute path string. The existing `createRequireFromPath()` method is now deprecated #27405. * Throw on `require('./path.mjs')`. This is technically a breaking change that should have landed with Node.js 12.0.0. It is necessary to have this to keep the possibility for a future minor version to load ES Modules with the require function. #27417 * repl: * The REPL now supports multi-line statements using `BigInt` literals as well as public and private class fields and methods. #27400 * The REPL now supports tab autocompletion of file paths with `fs` methods. #26648 * meta: * Added Christian Clauss (https://github.com/cclauss) to collaborators. #27554 PR-URL: #27578
