# Run a builder, flip exit code, save log and fix outputs
#
# Sub-goals:
# - Delegate to another original builder passed via args
# - Save the build log to output for further checks
# - Make the derivation succeed if the original builder fails
# - Make the derivation fail if the original builder returns exit code 0
#
# Requirements:
# This runs before, without and after stdenv. Do not modify the environment;
# especially not before invoking the original builder. For example, use
# "@" substitutions instead of PATH.
# Do not export any variables.
# Stricter bash
set -eu
# ------------------------
# Run the original builder
