child_process: exit spawnSync with null on signal #11288

cjihrig · 2017-02-10T15:03:41Z

This commit sets the spawnSync() exit code to null when the child is killed via signal. This brings the behavior more in sync with spawn().

Fixes: #11284

+  if (exit_status_ >= 0) {
+    if (term_signal_ > 0)
+      js_result->Set(env()->status_string(), Null(env()->isolate()));
+    else


I know it didn't have them originally, but can we please add braces here (and around the if block for completeness), since the block spans more than one line?

Personally, this looks like a bug fix to me, not semver-major, why should reporting an exit status of 0 for a child that did not exit be a feature?

Maybe it shouldn't get LTSed down to 4.x and 6.x (or maybe it should), but seems a good idea for 7.x.

cjihrig · 2017-02-13T23:06:30Z

I'm fine with this being a bug fix. I just labeled it semver major to be on the safe side.

I keep seeing build failures like this in the CI. I'm assuming they are unrelated.

Just to confirm before moving this to staging. Are we sure about this not being semver-major?
