Description of change

test-stdout-buffer-flush-on-exit was not failing reliably on POSIX
machines and not failing at all on Windows. Revised test fails reliably
on POSIX and is skipped (in CI) on Windows where the issue does not
exist.

Fixes: #6527

test/known_issues/test-stdout-buffer-flush-on-exit.js

Can't you just calculate Math.pow(2, exponent) once in the parent and pass it as argument to the child?

test/known_issues/test-stdout-buffer-flush-on-exit.js

Is the console.log() needed, or can it be dropped?

I don’t know if it’s needed, but I’d like to have some way of knowing at what length the test failed after it has run.

I accidentally left it in from debugging. I can add it to the assert message, perhaps.

cjihrig · 2016-05-04T13:04:25Z

LGTM with nits addressed.

addaleax · 2016-05-04T13:45:52Z

LGTM, maybe with @santigimeno’s nit addressed if that works too.

Nits addressed.

`test-stdout-buffer-flush-on-exit` was not failing reliably on POSIX machines and not failing at all on Windows. Revised test fails reliably on POSIX and is skipped (in CI) on Windows where the issue does not exist. Fixes: nodejs#6527

test/known_issues/test-stdout-buffer-flush-on-exit.js

+[16, 18, 20].forEach((exponent) => {
+  const bigNum = Math.pow(2, exponent);
+  const longLine = lineSeed.repeat(bigNum);
+  const cmd = `${process.execPath} ${__filename} child ${exponent} ${bigNum}`;


I think the exponent argument is not needed anymore

Strictly speaking, that's true, but I left it in for the assert message.

santigimeno · 2016-05-05T10:07:07Z

Still LGTM with one nit
