stream: don't emit 'data' after 'error' or 'close' #39639

As per doc we should not emit further events after 'close' and only 'close' after 'error'.

Fixes: #39630

Otherwise we can have unexpected bugs, a typical case that I've had in production was something like:

fs.open(path, 'w', (err, fd) => {
  src.on('data', chunk => {
    fs.write(fd, chunk)
  })
  src.on('close', () => {
    fs.close(fd)
  })
})

Where we keep writing to fd after it's been closed which is undefined behavior.

Note that it's still possible to read buffered data using read(), it's just that we don't emit 'data' when doing so.

This breaks ws. I think I can work around that but backporting it to unsupported release lines to fix compatibility with the next major version of Node.js is a bit of a pain.

Yeah, this is what I had expected from reading the docs.

Perhaps the docs for 'destroy' should also be updated to explain that it should cause the stream free any internal resources except not any locally buffered reads previously pushed into it?

@nodejs/tsc This needs another TSC approval. Or does the author count in terms of TSC approval?

Use the chunk returned by `socket.read()` to handle the buffered data
instead of relying on a `'data'` event emitted after the `'close'`
event.

OpenSSL 3.0:

Node.js now includes OpenSSL 3.0, specifically https://github.com/quictls/openssl
which provides QUIC support.

While OpenSSL 3.0 APIs should be mostly compatible with those provided
by OpenSSL 1.1.1, we do anticipate some ecosystem impact due to
tightened restrictions on the allowed algorithms and key sizes.

If you hit an `ERR_OSSL_EVP_UNSUPPORTED` error in your application with
Node.js 17, it’s likely that your application or a module you’re using
is attempting to use an algorithm or key size which is no longer allowed
by default with OpenSSL 3.0. A command-line option,
`--openssl-legacy-provider`, has been added to revert to the legacy
provider as a temporary workaround for these tightened restrictions.

For details about all the features in
OpenSSL 3.0 please see https://www.openssl.org/blog/blog/2021/09/07/OpenSSL3.Final.

OpenSSL 3.0:

Node.js now includes OpenSSL 3.0, specifically https://github.com/quictls/openssl
which provides QUIC support.

While OpenSSL 3.0 APIs should be mostly compatible with those provided
by OpenSSL 1.1.1, we do anticipate some ecosystem impact due to
tightened restrictions on the allowed algorithms and key sizes.

If you hit an `ERR_OSSL_EVP_UNSUPPORTED` error in your application with
Node.js 17, it’s likely that your application or a module you’re using
is attempting to use an algorithm or key size which is no longer allowed
by default with OpenSSL 3.0. A command-line option,
`--openssl-legacy-provider`, has been added to revert to the legacy
provider as a temporary workaround for these tightened restrictions.

For details about all the features in
OpenSSL 3.0 please see https://www.openssl.org/blog/blog/2021/09/07/OpenSSL3.Final.

V8 9.5:

The V8 JavaScript engine is updated to V8 9.5. This release comes with
additional supported types for the `Intl.DisplayNames` API and Extended
`timeZoneName` options in the `Intl.DateTimeFormat` API. You can read
more details in the V8 9.5 release post https://v8.dev/blog/v8-release-95.

Readline Promise API:

The `readline` module provides an interface for reading data from a
Readable stream (such as `process.stdin`) one line at a time.

Other Notable Changes:

- (SEMVER-MAJOR) dns: default to verbatim=true in dns.lookup()
  (treysis) [#39987]
- (SEMVER-MAJOR) errors: print Node.js version on fatal exceptions that
  cause exit
  (Divlo) [#38332]
- deps: upgrade npm to 8.1.0
  (npm team) [#40463]
- (SEMVER-MINOR) fs: add FileHandle.prototype.readableWebStream()
  (James M Snell) [#39331]
