check / check (push) Waiting to run
make asupdate piped the generator into gzip, so the target saw gzip's exit status. A failed download replaced pkg/asinfo/asdata.json.gz with an empty file and the target still exited 0. The target now runs the new script/asupdate. It writes the output of cmd/asinfo-gen to a temporary file. Only when the generator succeeds does it compress the list and move it into place. Otherwise it leaves the file alone and exits non-zero. The generator now fails when as.csv holds no AS. The generator reads as.csv from ipverse/as-metadata, the source's new name. The list it builds there is unchanged, so no new list is committed. Model: opus-5-5
