Comparing any value to any non-RegExp literal or undefined using
strictEqual (or notStrictEqual) passes if and only if deepStrictEqual
(or notDeepStrictEqual, respectively) passes.
Unnecessarily using deep comparisons adds confusion.
This patch adds an ESLint rule that forbids the use of deepStrictEqual
and notDeepStrictEqual when the expected value (i.e., the second
argument) is a non-RegExp literal or undefined.
For reference, an ESTree literal is defined as follows.
extend interface Literal <: Expression {
type: "Literal";
value: string | boolean | null | number | RegExp | bigint;
}
The value `undefined` is an `Identifier` with `name: 'undefined'`.

This will be a start to generalize all argument validation
errors. As currently we throw ARG/OPT, OUT_OF_RANGE, and other more
specific errors.
The OPT errors didn't bring much to the errors as it's just another
variant of ARG error which is sometimes more confusing (some of our code
used OPT errors to denote just argument validation errors presumably
because of similarity of OPT to 'option' and not 'options-object')
and they don't specify the name of the options object where the invalid
value is located. Much better approach would be to just specify path
to the invalid value in the name of the value as it is done in this PR
(i.e. 'options.format', 'options.publicKey.type' etc)
Also since this decreases a variety of errors we have it'd be easier to
reuse validation code across the codebase.

This completely refactors the `expectsError` behavior: so far it's
almost identical to `assert.throws(fn, object)` in case it was used
with a function as first argument. It had a magical property check
that allowed to verify a functions `type` in case `type` was passed
used in the validation object. This pattern is now completely removed
and `assert.throws()` should be used instead.
The main intent for `common.expectsError()` is to verify error cases
for callback based APIs. This is now more flexible by accepting all
validation possibilites that `assert.throws()` accepts as well. No
magical properties exist anymore. This reduces surprising behavior
for developers who are not used to the Node.js core code base.
This has the side effect that `common` is used significantly less
frequent.

ERR_INVALID_ARG_TYPE is the most common error used throughout the
code base. This improves the error message by providing more details
to the user and by indicating more precisely which values are allowed
ones and which ones are not.
It adds the actual input to the error message in case it's a primitive.
If it's a class instance, it'll print the class name instead of
"object" and "falsy" or similar entries are not named "type" anymore.

Historically `error.errno` of system errors thrown by Node.js
can sometimes be the same as `err.code`, which are string
representations of the error numbers. This is useless and incorrect,
and results in an information loss for users since then they
will have to resort to something like
`process.binding('uv'[`UV_${errno}`])` to get to the numeric
error codes.
This patch corrects this behavior by always setting `error.errno`
to be negative numbers. For fabricated errors like `ENOTFOUND`,
`error.errno` is now undefined since there is no numeric equivalent
for them anyway. For c-ares errors, `error.errno` is now undefined
because the numeric representations (negated) can be in conflict
with libuv error codes - this is fine since numeric codes was
not available for c-ares errors anyway.
Users can use the public API `util.getSystemErrorName(errno)`
to retrieve string codes for these numbers.

This commit removes `common.crashOnUnhandledRejection()` and adds
`common.disableCrashOnUnhandledRejection()`.
To reduce the risk of mistakes and make writing tests that involve
promises simpler, always install the unhandledRejection hook in tests
and provide a way to disable it for the rare cases where it's needed.

Issue 1: make invalid setServers yield uniform error
Behavior:
dns.setServers throws a null pointer dereference on some inputs.
Expected behavior was the more pleasant
TypeError [ERR_INVALID_IP_ADDRESS] ...
Root cause(s?):
- Dereferencing the result of a regex match without confirming
that there was a match.
- assuming the capture of an optional group (?)
Solution:
Confirm the match, and handle a missing port cleanly.
Tests: I added tests for various unusual inputs.
Issue 2: revise quadratic regex in setServers
Problem:
The IPv6 regex was quadratic.
On long malicious input the event loop could block.
The security team did not deem it a security risk,
but said a PR was welcome.
Solution:
Revise the regex to a linear-complexity version.
Tests:
I added REDOS tests to the "oddities" section.
