# 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.
