Node: CHECK failure in ResetStdio on >=12.5.0

[devsnek]

Check failure is this: ../src/node.cc:649:void node::ResetStdio(): Assertion(err) != (-1)' failed.`

https://github.com/nodejs/node/blob/dec5b2258a853b524e125542667b5b2dfc5afb74/src/node.cc#L646-L649

Reproduction:

1. Make sure you are on >=12.5.0
2. clone https://github.com/engine262/engine262
3. npm run build && npm run test
4. Tests start running, hit ctrl+c to kill it
5. Check failure happens consistently here

cc @bnoordhuis it looks like this is from 5872705796d

Same issue with protractor testing (npm run e2e).

@devsnek Are you on macOS? This doesn’t seem to happen with Linux, which makes it hard to debug for me. In any case, it might be good to know what errno is in that case.

Also, side note, another, different issue with the same commit was reported: https://github.com/nodejs/node/pull/24260#issuecomment-506922414

[devsnek]

@addaleax i'm on arch linux. i'll compile it to print errno and report back

[devsnek]

@addaleax

i found out, just doing npm run test is not enough, you have to spawn node with child_process and then ctrl+c it (i have a script runner i use that abstracts away npm, cargo, make, etc, which is why it reproduced for me originally)

require('child_process').spawn('node', ['test/test262.js'], {
  stdio: 'inherit',
});

output is:

errno 0
errno 2
errno 2
errno 0
errno 2
errno 2
errno 0
errno 2
errno 2
errno 2
errno 2
errno 2
errno 5

Errno 5 is EIO. Basically the kernel is saying something went wrong without going into specifics, but I guess it's because the tty went away somehow. I'll open a PR to accept that error.

The fix will be available in the next node release

[kahan002]

upgrading from node 12.5.0 to 12.16.3 fixed it.
