doc: add legacy status #37784

jasnell · 2021-03-17T19:43:10Z

Adds a new "Legacy" option to the stability index. The idea here is to give us another alternative to deprecating. Legacy code is still subject to semver rules but is specifically called out as legacy and to be avoided.

Marks the legacy URL parser as legacy, removing deprecated.

It could be worth also updating the other history sections so they are consistent:

It's also worth noting that the light mode version is not readable, it's probably something we want to fix before landing:

ljharb · 2021-03-18T03:17:09Z

What’s not readable about the light mode version?

marsonya · 2021-03-18T05:14:19Z

What’s not readable about the light mode version?

The Stability note below the table is not visible in the light version.

Notable changes: Diagnostics channel (experimental module): `diagnostics_channel` is a new experimental module that provides an API to create named channels to report arbitrary message data for diagnostics purposes. The module was initially introduced in Node.js v15.1.0 and is backported to v14.17.0 to enable testing it at a larger scale. With `diagnostics_channel`, Node.js core and module authors can publish contextual data about what they are doing at a given time. This could be the hostname and query string of a mysql query, for example. Just create a named channel with `dc.channel(name)` and call `channel.publish(data)` to send the data to any listeners to that channel. ```js const dc = require('diagnostics_channel'); const channel = dc.channel('mysql.query'); MySQL.prototype.query = function query(queryString, values, callback) { // Broadcast query information whenever a query is made channel.publish({ query: queryString, host: this.hostname, }); this.doQuery(queryString, values, callback); }; ``` Channels are like one big global event emitter but are split into separate objects to ensure they get the best performance. If nothing is listening to the channel, the publishing overhead should be as close to zero as possible. Consuming channel data is as easy as using `channel.subscribe(listener)` to run a function whenever a message is published to that channel. ```js const dc = require('diagnostics_channel'); const channel = dc.channel('mysql.query'); channel.subscribe(({ query, host }) => { console.log(`mysql query to ${host}: ${query}`); }); ``` The data captured can be used to provide context for what an app is doing at a given time. This can be used for things like augmenting tracing data, tracking network and filesystem activity, logging queries, and many other things. It's also a very useful data source for diagnostics tools to provide a clearer picture of exactly what the application is doing at a given point in the data they are presenting.

UUID support in the crypto module: The new `crypto.randomUUID()` method now allows to generate random [RFC 4122](https://www.rfc-editor.org/rfc/rfc4122.txt) Version 4 UUID strings: ```js const { randomUUID } = require('crypto'); console.log(randomUUID()); // 'aa7c91a1-f8fc-4339-b9db-f93fc7233429' ``` Contributed by James M Snell (#36729. Experimental support for `AbortController` and `AbortSignal`: Node.js 14.17.0 adds experimental partial support for `AbortController` and `AbortSignal`. Both constructors can be enabled globally using the `--experimental-abortcontroller` flag. Additionally, several Node.js APIs have been updated to support `AbortSignal` for cancellation. It is not mandatory to use the built-in constructors with them. Any spec-compliant third-party alternatives should be compatible. `AbortSignal` support was added to the following methods: * `child_process.exec` * `child_process.execFile` * `child_process.fork` * `child_process.spawn` * `dgram.createSocket` * `events.on` * `events.once` * `fs.readFile` * `fs.watch` * `fs.writeFile` * `http.request` * `https.request` * `http2Session.request` * The promisified variants of `setImmediate` and `setTimeout` Other notable changes: * doc: * revoke deprecation of legacy url, change status to legacy (James M Snell) (#37784) * add legacy status to stability index (James M Snell) (#37784) * upgrade stability status of report API (Gireesh Punathil) (#35654) * deps: * V8: Backport various patches for Apple Silicon support (BoHong Li) (#38051) * update ICU to 68.1 (Michaël Zasso) (#36187) * upgrade to libuv 1.41.0 (Colin Ihrig) (#37360) * http: * add http.ClientRequest.getRawHeaderNames() (simov) (#37660) * report request start and end with diagnostics\_channel (Stephen Belanger) (#34895) * util: * add getSystemErrorMap() impl (eladkeyshawn) (#38101) PR-URL: #38507
