From 754e829b3598cd07869fdc1339caae2cf0b04dbf Mon Sep 17 00:00:00 2001 From: Abdessamad Derraz <3028866+Abdess@users.noreply.github.com> Date: Wed, 1 Apr 2026 12:22:50 +0200 Subject: [PATCH] feat: add pack integrity test and integrate into pipeline Extract each platform ZIP to tmp/ (real filesystem, not /tmp tmpfs) and verify every declared file exists at the correct path with the correct hash per the platform's native verification mode. Handles ZIP inner content verification (checkInsideZip, md5_composite, inner ROM MD5) and path collision deduplication. Integrated as pipeline step 6/8. Renumber all pipeline steps to be sequential (was skipping from 5 to 8). --- scripts/pipeline.py | 48 ++++--- tests/test_pack_integrity.py | 264 +++++++++++++++++++++++++++++++++++ 2 files changed, 294 insertions(+), 18 deletions(-) create mode 100644 tests/test_pack_integrity.py diff --git a/scripts/pipeline.py b/scripts/pipeline.py index 95912677..b7dff941 100644 --- a/scripts/pipeline.py +++ b/scripts/pipeline.py @@ -99,7 +99,7 @@ def check_consistency(verify_output: str, pack_output: str) -> bool: v = parse_verify_counts(verify_output) p = parse_pack_counts(pack_output) -
