test_runner: support test plans

It is now possible to count the number of assertions and subtests that are expected to run within a test. If the number of assertions and subtests that run does not match the expected count, the test will fail.

test('top level test', (t) => {
  t.plan(2);
  t.assert.ok('some relevant assertion here');
  t.subtest('subtest', () => {});
});

Contributed by Colin Ihrig in #52860

inspector: introduce the --inspect-wait flag

This release introduces the --inspect-wait flag, which allows debugger to wait for attachement. This flag is useful when you want to debug the code from the beginning. Unlike --inspect-brk, which breaks on the first line, this flag waits for debugger to be connected and then runs the code as soon as a session is established.

Contributed by Kohei Ueno in #52734

zlib: expose zlib.crc32()

This release exposes the crc32() function from zlib to user-land.

It computes a 32-bit Cyclic Redundancy Check checksum of data. If
value is specified, it is used as the starting value of the checksum,
otherwise, 0 is used as the starting value.

The CRC algorithm is designed to compute checksums and to detect error
in data transmission. It's not suitable for cryptographic authentication.

const zlib = require('node:zlib');
const { Buffer } = require('node:buffer');

let crc = zlib.crc32('hello');  // 907060870
crc = zlib.crc32('world', crc);  // 4192936109

crc = zlib.crc32(Buffer.from('hello', 'utf16le'));  // 1427272415
crc = zlib.crc32(Buffer.from('world', 'utf16le'), crc);  // 4150509955

cli: allow running wasm in limited vmem with --disable-wasm-trap-handler

By default, Node.js enables trap-handler-based WebAssembly bound
checks. As a result, V8 does not need to insert inline bound checks
int the code compiled from WebAssembly which may speedup WebAssembly
execution significantly, but this optimization requires allocating
a big virtual memory cage (currently 10GB). If the Node.js process
does not have access to a large enough virtual memory address space
due to system configurations or hardware limitations, users won't
be able to run any WebAssembly that involves allocation in this
virtual memory cage and will see an out-of-memory error.

$ ulimit -v 5000000
$ node -p "new WebAssembly.Memory({ initial: 10, maximum: 100 });"
[eval]:1
new WebAssembly.Memory({ initial: 10, maximum: 100 });
^

RangeError: WebAssembly.Memory(): could not allocate memory
    at [eval]:1:1
    at runScriptInThisContext (node:internal/vm:209:10)
    at node:internal/process/execution:118:14
    at [eval]-wrapper:6:24
    at runScript (node:internal/process/execution:101:62)
    at evalScript (node:internal/process/execution:136:3)
    at node:internal/main/eval_string:49:3

--disable-wasm-trap-handler disables this optimization so that
users can at least run WebAssembly (with a less optimial performance)
when the virtual memory address space available to their Node.js
process is lower than what the V8 WebAssembly memory cage needs.

fs: add stacktrace to fs/promises

Sync functions in fs throwed an error with a stacktrace which is helpful for debugging. But functions in fs/promises throwed an error without a stacktrace. This commit adds stacktraces by calling Error.captureStacktrace and re-throwing the error.

report: add --report-exclude-network option

New option --report-exclude-network, also available as report.excludeNetwork, enables the user to exclude networking interfaces in their diagnostic report. On some systems, this can cause the report to take minutes to generate so this option can be used to optimize that.

v8: implement v8.queryObjects() for memory leak regression testing

This is similar to the queryObjects() console API provided by the Chromium DevTools console. It can be used to search for objects that have the matching constructor on its prototype chain in the heap after a full garbage collection, which can be useful for memory leak regression tests.
To avoid surprising results, users should avoid using this API on constructors whose implementation they don't control, or on constructors that can be invoked by other parties in the application.

To avoid accidental leaks, this API does not return raw references to the objects found. By default, it returns the count of the objects found. If options.format is 'summary', it returns an array containing brief string representations for each object. The visibility provided in this API is similar to what the heap snapshot provides, while users can save the cost of serialization and parsing and directly filer the target objects during the search.

We have been using this API internally for the test suite, which has been more stable than any other leak regression testing strategies in the CI. With a public implementation we can now use the public API instead.

const { queryObjects } = require('node:v8');
class A { foo = 'bar'; }
console.log(queryObjects(A)); // 0
let a = new A();
console.log(queryObjects(A)); // 1
// [ "A { foo: 'bar' }" ]
console.log(queryObjects(A, { format: 'summary' }));

// Release the object.
a = null;
// Search again. queryObjects() includes a full garbage collection
// so a should disappear.
console.log(queryObjects(A)); // 0

class B extends A { bar = 'qux'; }
// The child class B's prototype has A's prototype on its prototype chain
// so the prototype object shows up too.
console.log(queryObjects(A, { format: 'summary' })); // [ A {}' ]

module: implement NODE_COMPILE_CACHE for automatic on-disk code caching

This patch implements automatic on-disk code caching that can be enabled
via an environment variable NODE_COMPILE_CACHE=/path/to/cache/dir.

When set, whenever Node.js compiles a CommonJS or a ECMAScript Module,
it will use on-disk V8 code cache
persisted in the specified directory
to speed up the compilation. This may slow down the first load of a
module graph, but subsequent loads of the same module graph may get
a significant speedup if the contents of the modules do not change.
Locally, this speeds up loading of test/fixtures/snapshot/typescript.js
from ~130ms to ~80ms.

To clean up the generated code cache, simply remove the directory.
It will be recreated the next time the same directory is used for
NODE_COMPILE_CACHE.

Compilation cache generated by one version of Node.js may not be used
by a different version of Node.js. Cache generated by different versions
of Node.js will be stored separately if the same directory is used
to persist the cache, so they can co-exist.

Caveat: currently when using this with V8 JavaScript code coverage, the
coverage being collected by V8 may be less precise in functions that are
deserialized from the code cache. It's recommended to turn this off when
running tests to generate precise coverage.
