v12.16.0 proposal #31691

MylesBorins · 2020-02-08T02:03:46Z

2020-02-11, Version 12.16.0 'Erbium' (LTS), @targos

Notable changes

New assert APIs

The assert module now provides experimental assert.match() and
assert.doesNotMatch() methods. They will validate that the first argument is a
string and matches (or does not match) the provided regular expression:

const assert = require('assert').strict;

assert.match('I will fail', /pass/);
// AssertionError [ERR_ASSERTION]: The input did not match the regular ...

assert.doesNotMatch('I will fail', /fail/);
// AssertionError [ERR_ASSERTION]: The input was expected to not match the ...

This is an experimental feature.

Ruben Bridgewater #30929.

Advanced serialization for IPC

The child_process and cluster modules now support a serialization option
to change the serialization mechanism used for IPC. The option can have one of
two values:

'json' (default): JSON.stringify() and JSON.parse() are used. This is
how message serialization was done before.
'advanced': The serialization API of the v8 module is used. It is based on
the HTML structured clone algorithm
and is able to serialize more built-in JavaScript object types, such as
BigInt, Map, Set etc. as well as circular data structures.

Anna Henningsen #30162.

CLI flags

The new --trace-exit CLI flag makes Node.js print a stack trace whenever the
Node.js environment is exited proactively (i.e. by invoking the process.exit()
function or pressing Ctrl+C).

legendecas #30516.

The new --trace-uncaught CLI flag makes Node.js print a stack trace at the
time of throwing uncaught exceptions, rather than at the creation of the Error
object, if there is any.
This option is not enabled by default because it may affect garbage collection
behavior negatively.

Anna Henningsen #30025.

The --disallow-code-generation-from-strings V8 CLI flag is now whitelisted in
the NODE_OPTIONS environment variable.

Shelley Vohr #30094.

New crypto APIs

For DSA and ECDSA, a new signature encoding is now supported in addition to the
existing one (DER). The verify and sign methods accept a dsaEncoding
option, which can have one of two values:

'der' (default): DER-encoded ASN.1 signature structure encoding (r, s).
'ieee-p1363': Signature format r || s as proposed in IEEE-P1363.

Tobias Nießen #29292.

A new method was added to Hash: Hash.prototype.copy. It makes it possible to
clone the internal state of a Hash object into a new Hash object, allowing
to compute the digest between updates:

// Calculate a rolling hash.
const crypto = require('crypto');
const hash = crypto.createHash('sha256');

hash.update('one');
console.log(hash.copy().digest('hex'));

hash.update('two');
console.log(hash.copy().digest('hex'));

hash.update('three');
console.log(hash.copy().digest('hex'));

// Etc.

Ben Noordhuis #29910.

Dependency updates

libuv was updated to 1.34.0. This includes fixes to uv_fs_copyfile() and
uv_interface_addresses() and adds two new functions: uv_sleep() and
uv_fs_mkstemp().

Colin Ihrig #30783.

V8 was updated to 7.8.279.23. This includes performance improvements to object
destructuring, RegExp match failures and WebAssembly startup time.
The official release notes are available at https://v8.dev/blog/v8-release-78.

Michaël Zasso #30109.

New EventEmitter APIs

The new EventEmitter.on static method allows to async iterate over events:

const { on, EventEmitter } = require('events');

(async () => {

  const ee = new EventEmitter();

  // Emit later on
  process.nextTick(() => {
    ee.emit('foo', 'bar');
    ee.emit('foo', 42);
  });

  for await (const event of on(ee, 'foo')) {
    // The execution of this inner block is synchronous and it
    // processes one event at a time (even with await). Do not use
    // if concurrent execution is required.
    console.log(event); // prints ['bar'] [42]
  }

})();

Matteo Collina #27994.

It is now possible to monitor 'error' events on an EventEmitter without
consuming the emitted error by installing a listener using the symbol
EventEmitter.errorMonitor:

const myEmitter = new MyEmitter();

myEmitter.on(EventEmitter.errorMonitor, (err) => {
  MyMonitoringTool.log(err);
});

myEmitter.emit('error', new Error('whoops!'));
// Still throws and crashes Node.js

Gerhard Stoebich #30932.

Using async functions with event handlers is problematic, because it
can lead to an unhandled rejection in case of a thrown exception:

const ee = new EventEmitter();

ee.on('something', async (value) => {
  throw new Error('kaboom');
});

The experimental captureRejections option in the EventEmitter constructor or
the global setting change this behavior, installing a
.then(undefined, handler) handler on the Promise. This handler routes the
exception asynchronously to the Symbol.for('nodejs.rejection') method if there
is one, or to the 'error' event handler if there is none.

const ee1 = new EventEmitter({ captureRejections: true });
ee1.on('something', async (value) => {
  throw new Error('kaboom');
});

ee1.on('error', console.log);

const ee2 = new EventEmitter({ captureRejections: true });
ee2.on('something', async (value) => {
  throw new Error('kaboom');
});

ee2[Symbol.for('nodejs.rejection')] = console.log;

Setting EventEmitter.captureRejections = true will change the default for all
new instances of EventEmitter.

EventEmitter.captureRejections = true;
const ee1 = new EventEmitter();
ee1.on('something', async (value) => {
  throw new Error('kaboom');
});

ee1.on('error', console.log);

This is an experimental feature.

Matteo Collina #27867.

Performance Hooks are no longer experimental

The perf_hooks module is now considered a stable API.

legendecas #31101.

Introduction of experimental WebAssembly System Interface (WASI) support

A new core module, wasi, is introduced to provide an implementation of the
WebAssembly System Interface specification.
WASI gives sandboxed WebAssembly applications access to the
underlying operating system via a collection of POSIX-like functions.

This is an experimental feature.

Colin Ihrig #30258.

The stress test workspace on that mac was eating a lot of space removed that which freed up about 7G which should allow the machine to work again @targos.

More worryingly I cant find about 20G worth of storage on that machine

PR-URL: #31691

Notable changes: New assert APIs The `assert` module now provides experimental `assert.match()` and `assert.doesNotMatch()` methods. They will validate that the first argument is a string and matches (or does not match) the provided regular expression This is an experimental feature. Ruben Bridgewater [#30929](#30929). Advanced serialization for IPC The `child_process` and `cluster` modules now support a `serialization` option to change the serialization mechanism used for IPC. The option can have one of two values: * `'json'` (default): `JSON.stringify()` and `JSON.parse()` are used. This is how message serialization was done before. * `'advanced'`: The serialization API of the `v8` module is used. It is based on the HTML structured clone algorithm. and is able to serialize more built-in JavaScript object types, such as `BigInt`, `Map`, `Set` etc. as well as circular data structures. Anna Henningsen [#30162](#30162). CLI flags The new `--trace-exit` CLI flag makes Node.js print a stack trace whenever the Node.js environment is exited proactively (i.e. by invoking the `process.exit()` function or pressing Ctrl+C). legendecas [#30516](#30516). ___ The new `--trace-uncaught` CLI flag makes Node.js print a stack trace at the time of throwing uncaught exceptions, rather than at the creation of the `Error` object, if there is any. This option is not enabled by default because it may affect garbage collection behavior negatively. Anna Henningsen [#30025](#30025). ___ The `--disallow-code-generation-from-strings` V8 CLI flag is now whitelisted in the `NODE_OPTIONS` environment variable. Shelley Vohr [#30094](#30094). New crypto APIs For DSA and ECDSA, a new signature encoding is now supported in addition to the existing one (DER). The `verify` and `sign` methods accept a `dsaEncoding` option, which can have one of two values: * `'der'` (default): DER-encoded ASN.1 signature structure encoding `(r, s)`. * `'ieee-p1363'`: Signature format `r || s` as proposed in IEEE-P1363. Tobias Nießen [#29292](#29292). ___ A new method was added to `Hash`: `Hash.prototype.copy`. It makes it possible to clone the internal state of a `Hash` object into a new `Hash` object, allowing to compute the digest between updates. Ben Noordhuis [#29910](#29910). Dependency updates libuv was updated to 1.34.0. This includes fixes to `uv_fs_copyfile()` and `uv_interface_addresses()` and adds two new functions: `uv_sleep()` and `uv_fs_mkstemp()`. Colin Ihrig [#30783](#30783). ___ V8 was updated to 7.8.279.23. This includes performance improvements to object destructuring, RegExp match failures and WebAssembly startup time. The official release notes are available at https://v8.dev/blog/v8-release-78. Michaël Zasso [#30109](#30109). New EventEmitter APIs The new `EventEmitter.on` static method allows to async iterate over events. Matteo Collina [#27994](#27994). ___ It is now possible to monitor `'error'` events on an `EventEmitter` without consuming the emitted error by installing a listener using the symbol `EventEmitter.errorMonitor`. Gerhard Stoebich [#30932](#30932). ___ Using `async` functions with event handlers is problematic, because it can lead to an unhandled rejection in case of a thrown exception. The experimental `captureRejections` option in the `EventEmitter` constructor or the global setting change this behavior, installing a `.then(undefined, handler)` handler on the `Promise`. This handler routes the exception asynchronously to the `Symbol.for('nodejs.rejection')` method if there is one, or to the `'error'` event handler if there is none. Setting `EventEmitter.captureRejections = true` will change the default for all new instances of `EventEmitter`. This is an experimental feature. Matteo Collina [#27867](#27867). Performance Hooks are no longer experimental The `perf_hooks` module is now considered a stable API. legendecas [#31101](#31101). Introduction of experimental WebAssembly System Interface (WASI) support A new core module, `wasi`, is introduced to provide an implementation of the [WebAssembly System Interface](https://wasi.dev/) specification. WASI gives sandboxed WebAssembly applications access to the underlying operating system via a collection of POSIX-like functions. This is an experimental feature. Colin Ihrig [#30258](#30258).
