Patch Changes
- Command shims on POSIX again
execa target that has no interpreter — a runtime binary such as the managed Node.js, or any bin without a shebang — instead of waiting on it. A shim that waited reported a target killed by a signal as exit code128+N(for example137forSIGKILL), so callers that distinguish a signal death from an exit code, such as CI runners and process supervisors, saw the wrong outcome.
