#!/usr/bin/env bash
# This script is meant to be used to mark failing hydra builds as broken in the meta attrs
# To use the script, you should pass the list of failing attrs as arguments to the script.
#
# Example: `cat failing-attrs | xargs ./pkgs/common-updater/scripts/mark-broken`
#
# Generating a list of failing attrs: (this should be improved at a later date)
# - Go to the most recent hydra evaluation with all builds completed
# - Select the "builds still failing" tab
# - Highlight and select all packages, should be prefixed with `nixpkgs.`
# - Use regex and editor foo to leave only the attr names
# - Use the above example command to then execute the script
#
# OTHER NOTES:
# - The `denyFileList` and `denyAttrList` will likely need to be updated slightly
# to align with the conventions used in nixpkgs at execution time
# - Any attrs which failed for any reason will be written to `failed-marks.txt`.
# Those attrs will likely need manual attention as disablement will likely be conditional.
