fix(ci): prefetch quirk-library images before validation in the publish lane#76
Merged
Conversation
…sh lane First publish run (28555255212) failed: the 7 targets with 1.4-2 GB enterprise images (AlmaLinux/Rocky/CentOS/Amazon/Oracle/SUSE) all hit "wait for SSH: not ready before timeout" because the cold-cache image download ran inside each target's 12m validation window; the small Ubuntu/Debian images validated fine (real ubuntu-20.04-5.4 ringbuf fail + 3 passes). - prefetch all 11 images in parallel (xargs -P6 over source_url/ local_path parsed from the matrix profiles) in a dedicated step, so the per-target window only covers boot + validation; - free ~14 GB of unused hosted-runner toolchains (Android/.NET/GHC) first — the image set is ~11 GB against ~14 GB free on /; - per-target timeout 12m -> 15m for boot headroom.

First publish run (28555255212) failed with a clean diagnosis: the 7 targets backed by 1.4–2 GB enterprise images (AlmaLinux, Rocky, CentOS Stream, Amazon ×2, Oracle, SUSE) all hit
wait for SSH: not ready before timeout— the cold-cache image download ran inside each target's 12m validation window. The small Ubuntu/Debian images validated fine and produced real verdicts (ubuntu-20.04-5.4❌ ringbuf,ubuntu-20.10-5.8/ubuntu-22.04-5.15/debian-12-6.1✅), confirming the lane itself works.Fix
source_url/local_pathfor every matrix profile and download all 11 images in parallel (xargs -P6) before any VM boots — the per-target window now covers boot + validation only./.Will re-dispatch the workflow after merge to verify end-to-end.
