Multi-line JSON is more human readable, but harder for log aggregators
to consume, they usually require a log message per line, particularly
for JSON. Compact output will be consumable by aggregators such as EFK
(Elastic Search-Fluentd-Kibana), LogDNA, DataDog, etc.

If terminating the process with ctrl-c / SIGINT, prints a JS stacktrace
leading up to the currently executing code.
The feature would be enabled under option `--trace-sigint`.
Conditions of no stacktrace on sigint:
- has (an) active sigint listener(s);
- main thread is idle (i.e. uv polling), a message instead of stacktrace
would be printed.

`--es-module-specifier-resolution` is the only flagged portion of the

`--es-module-specifier-resolution` remains as an alias for backwards

Debugging HTTPS or TLS connections from a Node.js app with (for example)
Wireshark is unreasonably difficult without the ability to get the TLS
key log. In theory, the application can be modified to use the
`'keylog'` event directly, but for complex apps, or apps that define
there own HTTPS Agent (like npm), this is unreasonably difficult.
Use of the option triggers a warning to be emitted so the user is
clearly notified of what is happening and its effect.

Add a flag that makes Node.js print the stack trace at the
time of *throwing* uncaught exceptions, rather than at the
creation of the `Error` object, if there is any.
This is disabled by default because it affects GC behavior.

This patch implements --cpu-prof-interval to specify the sampling
interval of the CPU profiler started by --cpu-prof from the command
line. Also adjust the interval to 100 in test-cpu-prof.js to make
the test less flaky - it would fail if the time taken to finish
the workload is smaller than the sampling interval, which was
more likely on powerful machines when the interval was 1000.

To improve the integration of `--cpu-prof` with workers, this patch
splits `--cpu-prof-path` into `--cpu-prof-dir` and `--cpu-prof-name`,
so when a worker is launched from a thread that enables
`--cpu-prof`, if the parent thread sets `--cpu-prof-dir`, then the
profile of both thread would be generated to the specified directory.
If they end up specifying the same `--cpu-prof-name` the behavior
is undefined the last profile will overwritten the first one.

In the code base the word `report` is almost only used to refer to
the diagnostic report when it's a noun, and it's programmable
interface `process.report()` it not prefixed, so `report` should be

This patch introduces a CLI flag --cpu-prof that starts the V8
CPU profiler on start up, and ends the profiler then writes the
CPU profile before the Node.js instance (on the main thread or
the worker thread) exits. By default the profile is written to
`${cwd}/CPU.${yyyymmdd}.${hhmmss}.${pid}.${tid}.${seq}.cpuprofile`.
The patch also introduces a --cpu-prof-path flag for the user
to specify the path the profile will be written to.

This adds a flag to define the default behavior for unhandled
rejections. Three modes exist: `none`, `warn` and `strict`. The first
is going to silence all unhandled rejection warnings. The second
behaves identical to the current default with the excetion that no
deprecation warning will be printed and the last is going to throw
an error for each unhandled rejection, just as regular exceptions do.
It is possible to intercept those with the `uncaughtException` hook
as with all other exceptions as well.
This PR has no influence on the existing `unhandledRejection` hook.
If that is used, it will continue to function as before.

This introduces TLS1.3 support and makes it the default max protocol,
but also supports CLI/NODE_OPTIONS switches to disable it if necessary.
TLS1.3 is a major update to the TLS protocol, with many security
enhancements. It should be preferred over TLS1.2 whenever possible.
TLS1.3 is different enough that even though the OpenSSL APIs are
technically API/ABI compatible, that when TLS1.3 is negotiated, the
timing of protocol records and of callbacks broke assumptions hard-coded
into the 'tls' module.
This change introduces no API incompatibilities when TLS1.2 is
negotiated. It is the intention that it be backported to current and LTS
release lines with the default maximum TLS protocol reset to 'TLSv1.2'.
This will allow users of those lines to explicitly enable TLS1.3 if they
want.
API incompatibilities between TLS1.2 and TLS1.3 are:
- Renegotiation is not supported by TLS1.3 protocol, attempts to call
`.renegotiate()` will always fail.
- Compiling against a system OpenSSL lower than 1.1.1 is no longer
supported (OpenSSL-1.1.0 used to be supported with configure flags).
- Variations of `conn.write('data'); conn.destroy()` have undefined
behaviour according to the streams API. They may or may not send the
'data', and may or may not cause a ERR_STREAM_DESTROYED error to be
emitted. This has always been true, but conditions under which the write
suceeds is slightly but observably different when TLS1.3 is negotiated
vs when TLS1.2 or below is negotiated.
- If TLS1.3 is negotiated, and a server calls `conn.end()` in its
'secureConnection' listener without any data being written, the client
will not receive session tickets (no 'session' events will be emitted,
and `conn.getSession()` will never return a resumable session).
- The return value of `conn.getSession()` API may not return a resumable
session if called right after the handshake. The effect will be that
clients using the legacy `getSession()` API will resume sessions if
TLS1.2 is negotiated, but will do full handshakes if TLS1.3 is
negotiated. See https://github.com/nodejs/node/pull/25831 for more
information.
