Notable changes: New file system APIs: * Added a new function, `fs.readv` (with sync and promisified versions). This function takes an array of `ArrayBufferView` elements and will write the data it reads sequentially to the buffers (Sk Sajidul Kadir). #32356 * A new overload is available for `fs.readSync`, which allows to optionally pass any of the `offset`, `length` and `position` parameters. #32460 Other changes: * dns: * Added the `dns.ALL` flag, that can be passed to `dns.lookup()` with `dns.V4MAPPED` to return resolved IPv6 addresses as well as IPv4 mapped IPv6 addresses (murgatroid99). #32183 * http: * The default maximum HTTP header size was changed from 8KB to 16KB (rosaxny). #32520 * n-api: * Calls to `napi_call_threadsafe_function` from the main thread can now return the `napi_would_deadlock` status in certain circumstances (Gabriel Schulhof). #32689 * util: * Added a new `maxStrLength` option to `util.inspect`, to control the maximum length of printed strings. Its default value is `Infinity` (rosaxny). #32392 * worker: * Added support for passing a `transferList` along with `workerData` to the `Worker` constructor (Juan José Arboleda). #32278 New core collaborators: With this release, we welcome three new Node.js core collaborators: * himself65. #32734 * flarna (Gerhard Stoebich). #32620 * mildsunrise (Alba Mendez). #32525 PR-URL: #32813

This change adds the
dns.ALLflag and allows it to be passed in thedns.lookuphints option. I changed the relevant tests that I could find and added some basic documentation.The documentation I wrote for that flag is based on how it is documented in
man 3 getaddrinfo. However, the reason for this change is that we recently discovered thatgetaddrinfo(and thereforedns.lookup) behaves differently on different operating systems. In particular, on Linux it behaves as documented, but on Mac, the default behavior ofgetaddrinfois as though theAI_ADDRCONFIGflag is set, andAI_ALLmakes it act as though that flag is unset (i.e. the default Linux behavior). SettingAI_ALLappears to be the only way to get that behavior on Mac, and that is why I would like it to be available.I am not sure if it would be better to explicitly document that part of the OS-specific behavior in the
dnsmodule documentation.Checklist
