Mic92: fixed a bug and improved the progress logging:

{
  "dry_run": true,
  "targets": {
    "nar_infos": 150581
  },
  "removed": {
    "nars": 150581,
    "nar_infos": 150581,
    "errors": 0
  },
  "missing_in_s3": {
    "nars": 0,
    "nar_infos": 0
  }
}

Mic92: I pushed an updated version of the dangling refs parquet file which you should be able to run through simple gc to remove them just like with nixos images.

I also locally tweaked the dangling refs script to load those first order dangling refs into the deletion set and the result was no more dangling refs found:

==================================================
SUMMARY
==================================================
Entries with dangling refs: 0
No dangling references found

Had to fix a schema issue, pushed an update to the dataset and just tested it with a dry run:

{
  "dry_run": true,
  "targets": {
    "nar_infos": 105944
  },
  "removed": {
    "nars": 105944,
    "nar_infos": 105944,
    "errors": 0
  },
  "missing_in_s3": {
    "nars": 0,
    "nar_infos": 0
  }
}
