TypeError: "maxBuffer" must be an unsigned integer

8.x-pre behaves well.

With #10769 being semver-major, should we mark this as wont-fix?

[sam-github]

#10769 is probably semver-major because it added argument validation. That was a nice cleanup, but not necessary to fix this bug, it should be possible to re-express #10769 as a semver-minor and backport it.

@nodejs/lts what do you think of me backporting #10769 to fix this? Worth it?

@sam-github maybe add it to nodejs/Release#188?

Just a reminder to please also fix this in the documentation. I ran across this, found this bug, discovered that I could do var child = exec(cmd, {maxBuffer:Infinity}) and it works, but isn't documented. Thanks.

Removing v7.x label as that release line is no longer supported.

[gireeshpunathil]

I removed v4.x as it is not longer supported and have no intention to fix in that.
#node --version; node -e "require('child_process').execSync('date', {maxBuffer: Infinity})"
v10.0.0

So I guess once this is back ported to v6.x and doc updated, we are good to close this.

/cc @nodejs/release

@apapirovski - a one liner rationale for closing please?

[targos]

Looks like this was closed by mistake
