1# Run a builder, flip exit code, save log and fix outputs
2#
3# Sub-goals:
4# - Delegate to another original builder passed via args
5# - Save the build log to output for further checks
6# - Make the derivation succeed if the original builder fails
7# - Make the derivation fail if the original builder returns exit code 0
8#
9# Requirements:
10# This runs before, without and after stdenv. Do not modify the environment;
11# especially not before invoking the original builder. For example, use
12# "@" substitutions instead of PATH.
13# Do not export any variables.
