http, http2: remove default server timeout #27558

ofrobots · 2019-05-04T00:13:03Z

Timing out and closing the socket after two minutes have elapsed is
surprising and problematic for users. This behavior was specific to
Node.js, and doesn't seem to be common in other language runtimes.

Fixes: #27556

EDIT: CI: https://ci.nodejs.org/job/node-test-pull-request/22988/

In theory, I’m in favor of this change for all the reasons outlined in the original issue. That said, I worry about just how breaking this could be for some users... and not sure there’s a good way to quantify that side of it.

@apapirovski

That said, I worry about just how breaking this could be for some users... and not sure there’s a good way to quantify that side of it.

My expectation is that this is not very breaking for users. I can imagine some impact on buggy applications that leak sockets, but I'm not very concerned about that case. As a semver-major, this will go out in an odd-numbered release which lets us manage impact, and revert, if this is very breaky?

async-hooks/test-graph.http.js failed on one arm machine. This is relevant, and probably due to an overly specific async hooks graph.

ofrobots · 2019-05-07T21:25:49Z

With this PR the arm failure is flaky with a 0.5% chance of failure. Upon investigation it turns out that the test is flaky on master as well, but with a 0.1% chance of failure.

ofrobots · 2019-05-08T00:19:13Z

The flakiness is due to the following conditional timer we create to cache timestamps for http responses:

node/lib/internal/http.js

Line 22 in e006a85

setUnrefTimeout(resetCache, 1000 - d.getMilliseconds());

If we are unlucky (and we are unlucky 0.1% or 0.5% of the time on this ARM machine), this ends up creating a Timeout async resource and the test fails because it did not expect that particular Timeout resource in the graph. I'll open a separate issue/PR to get the test fixed. I don't think this should block this PR. Let me know if anyone disagrees.

I think this flaky test is related to adding a check for expected types in verify-graph.js done via #27477.
Before this the verify-graph tests were not failing even if all of the expected events were not present (that time it was HTTPParser which was renamed).

ofrobots · 2019-05-08T19:01:33Z

Here's a comparison CTIGM run for master: https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/1847/. Nothing in the delta looked suspicious, but fastify saw some EADDRINUSE in use errors. These are likely infrastructure issues, but I manually tested fastify test suite against this branch for good measure. Things seem to be green.

ofrobots · 2019-05-08T21:39:48Z

Thanks @Flarna, that makes sense. I have split the flaky test discussion into #27617.

I am planning to land this tomorrow (Thu).

gRPC has its own mechanisms for timing out a request, and requests should not timeout by default. Furthermore, the default timeout was removed from Node.js. Refs: nodejs/node#27558

Make it possible to override the default http server timeout. Ideally there should be no server timeout - as done on the master branch. This is a non-breaking way to enable platform providers to override the value.

Notable changes: * assert: * If the validation function passed to `assert.throws()` or `assert.rejects()` returns a value other than `true`, an assertion error will be thrown instead of the original error to highlight the programming mistake (Ruben Bridgewater). #28263 * If a constructor function is passed to validate the instance of errors thrown in `assert.throws()` or `assert.reject()`, an assertion error will be thrown instead of the original error (Ruben Bridgewater). #28263 * build: * Node.js releases are now built with default full-icu support. This means that all locales supported by ICU are now included and Intl-related APIs may return different values than before (Richard Lau). #29887 * The minimum Xcode version supported for macOS was increased to 10. It is still possible to build Node.js with Xcode 8 but this may no longer be the case in a future v13.x release (Michael Dawson). #29622 * child_process: * `ChildProcess._channel` (DEP0129) is now a Runtime deprecation (cjihrig). #27949 * console: * The output `console.timeEnd()` and `console.timeLog()` will now automatically select a suitable time unit instead of always using milliseconds (Xavier Stouder). #29251 * deps: * The V8 engine was updated to version 7.8. This includes performance improvements to object destructuring, memory usage and WebAssembly startup time (Myles Borins). #29694) * domain: * The domain's error handler is now executed with the active domain set to the domain's parent to prevent inner recursion (Julien Gilli). #26211 * fs: * The undocumented method `FSWatcher.prototype.start()` was removed (Lucas Holmquist). #29905 * Calling the `open()` method on a `ReadStream` or `WriteStream` now emits a runtime deprecation warning. The methods are supposed to be internal and should not be called by user code (Robert Nagy). #29061 * `fs.read/write`, `fs.readSync/writeSync` and `fd.read/write` now accept any safe integer as their `offset` parameter. The value of `offset` is also no longer coerced, so a valid type must be passed to the functions (Zach Bjornson). #26572 * http: * Aborted requests no longer emit the `end` or `error` events after `aborted` (Robert Nagy). #27984 #20077 * Data will no longer be emitted after a socket error (Robert Nagy). #28711 * The legacy HTTP parser (previously available under the `--http-parser=legacy` flag) was removed (Anna Henningsen). #29589 * The `host` option for HTTP requests is now validated to be a string value (Giorgos Ntemiris). #29568 * The `request.connection` and `response.connection` properties are now runtime deprecated. The equivalent `request.socket` and `response.socket` should be used instead (Robert Nagy). #29015 * http, http2: * The default server timeout was removed (Ali Ijaz Sheikh). #27558 * Brought 425 status code name into accordance with RFC 8470. The name changed from "Unordered Collection" to "Too Early" (Sergei Osipov). #29880 * lib: * The `error.errno` property will now always be a number. To get the string value, use `error.code` instead (Joyee Cheung). #28140 * module: * `module.createRequireFromPath()` is deprecated. Use `module.createRequire()` instead (cjihrig). #27951 * src: * Changing the value of `process.env.TZ` will now clear the tz cache. This affects the default time zone used by methods such as `Date.prototype.toString` (Ben Noordhuis). #20026 * stream: * The timing and behavior of streams was consolidated for a number of edge cases. Please look at the individual commits below for more information. PR-URL: #29504

- Remove default connection timeout - nodejs/node#27558. - Add client error listener.

The default timeout was removed from the HTTP module in node 13.x: nodejs/node#27558. I believe this is the most likely cause of fd leaks when running under current node versions.
