I think that all property getters do not have a setter accessible to users. That would mean there is no "security" reason to add them to primordials, it's just more convenient to not duplicate calls to Object.getOwnPropertyDescriptor, right? I wonder if there may be a performance impact on startup time and memory usage to add all those getters if we are not using them right away.

I think that all property getters do not have a setter accessible to users.

Modifying the code to count and log the number of encountered setters shows that there are 22 setters encountered by the primordials code.

Interesting, I stand corrected :)

Can you also replace this instance in buffer.js:

node/lib/buffer.js

Lines 119 to 121 in 7d45dd9

constTypedArrayProto_byteLength=uncurryThis(
ObjectGetOwnPropertyDescriptor(TypedArrayPrototype,
'byteLength').get);

It seems to introduce some performance regressions, but it seems to me it's unrelated code 🤔

Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case there are 384 comparisons, you can thus
expect the following amount of false-positive results:
19.20 false positives, when considering a 5% risk acceptance (*, **, ***),
3.84 false positives, when considering a 1% risk acceptance (**, ***),
0.38 false positives, when considering a 0.1% risk acceptance (***)

@aduh95 There’s apparently a way to only restart the failed CI builds from the https://ci.nodejs.org page (e.g.: https://ci.nodejs.org/job/node-test-pull-request/34677/) without needing to rerun all CI builds:

From #35811 (comment):

Best thing to do with unrelated failures is to use "Resume Build" on the left nav. That will rebuild only the Jenkins subtasks that failed before. I'll go ahead and click "Resume Build" right now so you don't have to.
Optional thing you can do if you want to be a good citizen: Check to make sure that there are open issues for the tests that failed.
If not, open an issue.
If there are open issues and they haven't been updated in a while, consider leaving a comment and a copy/paste of the error trace so that it's clear that the issue is ongoing (and a recent trace will be more accurate/useful than a dated one).
If there are open issues and they have been updated recently, consider opening a PR to mark the test flaky.

@ExE-Boss Can you rebase on top of c91e608 to fix the CI failure please?

ExE-Boss · 2020-12-02T22:12:13Z

@aduh95 Done.

IMHO this change makes the code harder to read. Would you agree to create a function to avoid repeating the code over and over:

functiondefineGetterAndSetter(desc,dest,prefix,key){const{ enumerable, get, set }=desc;Reflect.defineProperty(dest,`${prefix}Get${key}`,{value: uncurryThis(get),
enumerable
});if(set!==undefined){Reflect.defineProperty(dest,`${prefix}Set${key}`,{value: uncurryThis(set),
enumerable
});}}
