Previously when managing the importModuleDynamically callback of vm.compileFunction(), we use an ID number as the host defined option and maintain a per-Environment ID -> CompiledFnEntry map to retain the top-level referrer function returned by vm.compileFunction() in order to pass it back to the callback, but it would leak because with how we used v8::Persistent to maintain this reference, V8 would not be able to understand the cycle and would just think that the CompiledFnEntry was supposed to live forever. We made an attempt to make that reference known to V8 by making the CompiledFnEntry weak and using a private symbol to make CompiledFnEntry strongly references the top-level referrer function in nodejs#46785, but that turned out to be unsound, because the there's no guarantee that the top-level function must be alive while import() can still be initiated from that function, since V8 could discard the top-level function and only keep inner functions alive, so relying on the top-level function to keep the CompiledFnEntry alive could result in use-after-free which caused a revert of that fix. With this patch we use a symbol in the host defined options instead of a number, because with the stage-3 symbol-as-weakmap-keys proposal we could directly use that symbol to keep the referrer alive using a WeakMap. As a bonus this also keeps the other kinds of referrers alive as long as import() can still be initiated from that Script/Module, so this also fixes the long-standing crash caused by vm.Script being GC'ed too early when its importModuleDynamically callback still needs it.

As a result the ModuleWrap would be kept alive until the Environment is shut down, which would be a leak for user code. With the new symbol-based host-defined option we can just get the ModuleWrap from the JS-land WeakMap so there's now no need to maintain this strong reference. This would at least fix the leak for vm.SyntheticModule. vm.SourceTextModule is still leaking due to the strong persistent reference to the v8::Module.

Previously we simply create a lot of the target objects and check if the process crash due to OOM. Due to how we use emphemeron GC to handle memory management, which is inefficient but necessary for correctness, the tests can produce false positives as the GC isn't efficient enough to catch up with a very fast heap growth. This patch uses a new checkIfCollectable() utility to terminate the test early once we detect that any of the target object can actually be garbage collected. This should lower the chance of false positives. As a drive-by this also allows us to use setImmediate() to grow the heap even faster to make the tests run faster.

Users cannot access any API that can be used to return a module or module namespace in this callback without --experimental-vm-modules anyway, so this would eventually lead to a rejection. This patch rejects in this case with our own error message and use a constant host-defined option for the rejection, so that scripts with the same source can still be compiled using the compilation cache if no `import()` is actually called in the script.

This will aid migration by making the new syntax available across all currently supported Node.js release lines. This adds the `with` keyword which should be used in place of the previous `assert` keyword, which will be removed in a future semver-major Node.js release. For example, ```console import "foo" assert { ... } ``` should be replaced with ```console import "foo" with { ... } ``` For more details, see - [#​50134](nodejs/node#50134) - [#​51622](nodejs/node#51622) Contributed by Nicolò Ribaudo in [#​51136](nodejs/node#51136) and Antoine du Hamel in [#​50140](nodejs/node#50140). ##### Doc deprecation for `dirent.path` Please use newly added `dirent.parentPath` instead. Contributed by Antoine du Hamel in [#​50976](nodejs/node#50976) and [#​51020](nodejs/node#51020). ##### Experimental node-api feature flags Introduces an experimental feature to segregate finalizers that affect GC state. A new type called `node_api_nogc_env` has been introduced as the const version of `napi_env` and `node_api_nogc_finalize` as a variant of `napi_finalize` that accepts a `node_api_nogc_env` as its first argument. This feature can be turned off by defining `NODE_API_EXPERIMENTAL_NOGC_ENV_OPT_OUT`. Contributed by Gabriel Schulhof in [#​50060](nodejs/node#50060). ##### Root certificates updated to NSS 3.98 Certificates added: - Telekom Security TLS ECC Root 2020 - Telekom Security TLS RSA Root 2023 Certificates removed: - Security Communication Root CA ##### Updated dependencies - ada updated to 2.7.6. - base64 updated to 0.5.2. - c-ares updated to 1.27.0. - corepack updated to 0.25.2. - ICU updated to 74.2. Includes CLDR 44.1 and Unicode 15.1. - npm updated to 10.5.0. Fixes a regression in signals not being passed onto child processes. - simdutf8 updated to 4.0.8. - Timezone updated to 2024a. - zlib updated to 1.3.0.1-motley-40e35a7. ##### vm: fix V8 compilation cache support for vm.Script Previously repeated compilation of the same source code using `vm.Script` stopped hitting the V8 compilation cache after v16.x when support for `importModuleDynamically` was added to `vm.Script`, resulting in a performance regression that blocked users (in particular Jest users) from upgrading from v16.x. The recent fixes allow the compilation cache to be hit again for `vm.Script` when `--experimental-vm-modules` is not used even in the presence of the `importModuleDynamically` option, so that users affected by the performance regression can now upgrade. Ongoing work is also being done to enable compilation cache support for `vm.CompileFunction`.
