@rexagod Is this semver-major? It looks that way to me.

This will be equivalent to 'test', hence a valid header. See below.

node/lib/internal/http2/compat.js

Line 604 in a29d7c7

name = name.trim().toLowerCase();

Hm, I wonder, the http fails with ERR_INVALID_HTTP_TOKEN if you try to set the header name of ' test'.

Each header field consists
of a name followed by a colon (":") and the field value. Field names
are case-insensitive. The field value MAY be preceded by any amount
of LWS, though a single SP is preferred.

@lundibundi The RFC2616 for HTTP/1 states that the field value may be preceded by any amount of LWS, but nothing similar is stated for the field names. Furthermore, this is not a problem in HTTP/2 owing to the binary protocol.

That part of the RFC if referring to the format of the HTTP message (i.e. actual text representation of the message), not the specific field name/value. Just down below in that section, we can see
field-name = token
And the token is
token = 1*<any CHAR except CTLs or separators>

Therefore there shouldn't be any leading whitespace in the user-provided value for header name which our http/1 implementation is enforcing correctly (by throwing ERR_INVALID_HTTP_TOKEN).

It's fine to do that in a follow-up PR, I just mentioned it so that we won't forget about it.

@rexagod there are still a few comments to fix, then we can land.

rexagod · 2020-06-16T11:49:24Z

@mcollina I think all the comments have been resolved now. Please let me know if there's anything else left to fix here.

LGTM.

Making explicit that IMO the leading whitespace in header names can be handled in a follow-up PR since this PR already improves things in compat layer a bit and there is no need to handle everything in one PR.

Notable changes: Deprecations and Removals: - **build**: remove --build-v8-with-gn configure option (Yang Guo) (#27576) - **build**: drop support for VS2017 (Michaël Zasso) (#33694) - **doc**: move DEP0018 to End-of-Life (Rich Trott) (#35316) - **fs**: deprecation warning on recursive rmdir (Ian Sutherland) (#35562) - **lib**: add EventTarget-related browser globals (Anna Henningsen) (#35496) - **net**: remove long deprecated server.connections property (James M Snell) (#33647) - **repl**: remove deprecated repl.memory function (Ruben Bridgewater) (#33286) - **repl**: remove deprecated repl.turnOffEditorMode() function (Ruben Bridgewater) (#33286) - **repl**: remove deprecated repl.parseREPLKeyword() function (Ruben Bridgewater) (#33286) - **repl**: remove deprecated bufferedCommand property (Ruben Bridgewater) (#33286) - **repl**: remove deprecated .rli (Ruben Bridgewater) (#33286) - **src**: remove deprecated node debug command (James M Snell) (#33648) - **timers**: introduce timers/promises (James M Snell) (#33950) - **util**: change default value of `maxStringLength` to 10000 (unknown) (#32744) - **wasi**: drop --experimental-wasm-bigint requirement (Colin Ihrig) (#35415) npm 7 (#35631): Node.js 15 comes with a new major release of npm, npm 7. npm 7 comes with many new features - including npm workspaces and a new package-lock.json format. npm 7 also includes yarn.lock file support. One of the big changes in npm 7 is that peer dependencies are now installed by default. Throw On Unhandled Rejections (#33021): As of Node.js 15, the default mode for `unhandledRejection` is changed to `throw` (from `warn`). In `throw` mode, if an `unhandledRejection` hook is not set, the `unhandledRejection` is raised as an uncaught exception. Users that have an `unhandledRejection` hook should see no change in behavior, and it’s still possible to switch modes using the `--unhandled-rejections=mode` process flag. QUIC (#32379): Node.js 15 comes with experimental support QUIC, which can be enabled by compiling Node.js with the `--experimental-quic` configuration flag. The Node.js QUIC implementation is exposed by the core `net` module. V8 8.6 (#35415): The V8 JavaScript engine has been updated to V8 8.6 (V8 8.4 is the latest available in Node.js 14). Along with performance tweaks and improvements the V8 update also brings the following language features: * `Promise.any()` (from V8 8.5) * `AggregateError` (from V8 8.5) * `String.prototype.replaceAll()` (from V8 8.5) * Logical assignment operators `&&=`, `||=`, and `??=` (from V8 8.5) Other Notable Changes: -
