What

Child processes spawned through the exec helper now get an error listener on stdin. EPIPE, ECONNRESET and EOF are ignored as normal; any other error records the code, kills the child, and makes the call return exit code 1 with an error naming the failure.

Details
  • Applies to the non-throwing exec helper (execFileNoThrow), which previously handed back a partial result in this case.
Evidence

execFileNoThrow

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
