Failed tests: ┃ > out/Release/node /build/node-v23.2.0/test/parallel/test-os.js

Could you share the output of this test?

[JohnRTitor]

Could you point me how to do that? I am not familiar with nodePackages, just got the log from the Nix build command.

[aduh95]

As it says on the output:

For full logs, run 'nix log /nix/store/ahgdyngidcphsmb7zn5b1lny589pyjdc-nodejs-23.2.0.drv'.

From there, you can search for not ok (or for the test name, but I find not ok easier to remember).

[JohnRTitor]

Got it.

OK that's definitely interesting! Could you confirm if the test passes if you revert https://github.com/nodejs/node/commit/a094a8166cd772f89e92b5deef168e5e599fa815?

[LiviaMedeiros]

Does niceness on NixOS work differently than on most Unix systems? The os.constants.priority.PRIORITY_LOW is 19, there should be no numbers higher than that, and setting priority on same or lower level should be fine.

If it's indeed different, what's the returned value of require('node:os').type() on NixOS systems?

[JohnRTitor]

OK that's definitely interesting! Could you confirm if the test passes if you revert nodejs/node@a094a81?

Well this patch does not apply. https://github.com/JohnRTitor/nixpkgs/commit/24c5cc0adbf278652bdbf5695674f824f7f20c23

[aduh95]

Well this patch does not apply. JohnRTitor@24c5cc0

Ah right, my bad, that commit didn't make it into 23.2.0. I reckon we have this test disabled on macOS, the comment says it's sandbox related: https://github.com/NixOS/nixpkgs/blob/4f93e624c544fb86e60cba7620c0d29083258809/pkgs/development/web/nodejs/nodejs.nix#L312-L314

In any case, we should probably amend the Node.js test to not fail on EACCES

[JohnRTitor]

Nice, can we cherry-pick the commit here or will it be part of a minor patch release?

[JohnRTitor]

Looks like this does not directly apply either, we will either need to rebase and vendor the patch or disable the test, while we wait for a release.

[aduh95]

Well you would need to first apply https://github.com/nodejs/node/commit/a094a8166cd772f89e92b5deef168e5e599fa815 and confirm it's still an issue with that patch applies, then cherry-pick my commit on top of it. It should make its way to a future minor or patch release yes.

[JohnRTitor]

Does niceness on NixOS work differently than on most Unix systems?

I don't think it is. But I am not entirely sure.

If it's indeed different, what's the returned value of require('node:os').type() on NixOS systems?

@LiviaMedeiros

EDIT: I tried running node seperately on my system, it assigns 16 nice value to the node interpreter.

[JohnRTitor]

Well you would need to first apply nodejs/node@a094a81

I mean this fails to apply. 🥲

You need to fix the hash, you should get a different hash depending if you pass revert=true or not

Yep, this seems to be the issue. Before https://github.com/nodejs/node/commit/a094a8166cd772f89e92b5deef168e5e599fa815 the test niceness was hardcoded to 10; and process can't lower its niceness unless you're root. After applying that commit, it will check current priority and try 19 which should not cause EACCES.

[aduh95]

The hash you should be using is sha256-5FZfozYWRa1ZI/f+e+xpdn974Jg2DbiHbua13XUQP5E= for https://github.com/nodejs/node/commit/a094a8166cd772f89e92b5deef168e5e599fa815.patch?full_index=1

[JohnRTitor]

Yeah I was just building the package. Looks like we need both https://github.com/nodejs/node/commit/a094a8166cd772f89e92b5deef168e5e599fa815 and https://github.com/nodejs/node/pull/55863/commits/f60cc5871b3950a078356dbd30cb16ba64890916 for the test failure to be fixed.

[aduh95]

Can you clarify what's the behavior without https://github.com/nodejs/node/commit/f60cc5871b3950a078356dbd30cb16ba64890916? Same error as without https://github.com/nodejs/node/commit/a094a8166cd772f89e92b5deef168e5e599fa815?

[JohnRTitor]

The test indeed failed with just https://github.com/nodejs/node/commit/a094a8166cd772f89e92b5deef168e5e599fa815 applied and needed https://github.com/nodejs/node/commit/f60cc5871b3950a078356dbd30cb16ba64890916 to work.
