scripts/mark-broken: improve
This improves on the previous verison of this script.
Previously it only accepted one attr, and required
explicit passing of the "broken" value.
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-update/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.
