From 38ebecabb6e91bef3ed8d967eab5f170c6d25ad3 Mon Sep 17 00:00:00 2001 From: vasilito Date: Sun, 12 Jul 2026 11:02:27 +0300 Subject: [PATCH] phase 6.5: add --selftest mode to verify-patch-content + pre-push wiring Adds --selftest mode that runs 5 regression test cases against a temp directory. The temp dir is created OUTSIDE the parent git working tree (e.g. via /tmp/.tmp-redbear-selftest-/) so that the test's 'git log' commands don't pick up the parent repo's 100+ commits. Test cases: 1. patch with sig in fork target preserved 2. patch without sig in fork target orphan 3. no-target patch (no +++ b/ header) orphan (no-target) 4. patch with content-integrated target orphan (classification) 5. verify --report action produces per-orphan decision Bug fixed during dev: passing fork_dir to git log WITHOUT isolating it from the parent repo's git tree caused 50 'case2' keyword matches to leak in from the RedBear-OS parent repo's commit log, making case2 falsely classified as INTEGRATED. Fixed by using tempfile.mkdtemp(dir=os.path.dirname(REPO_ROOT)) to put the test fork dir OUTSIDE the parent git tree. Also fixed: audit_component now accepts an optional patches_dir arg (so selftest can pass a non-default patches path without modifying the main code path). Also fixed: 'if not target_path or target_path == \'?\'' check in suggest_action_for_orphan to handle the literal '?' sentinel that audit_component uses for no-target orphans. Wired into pre-push-checks.sh as check #3b (verify-patch-content-selftest). Total: 7 pre-push checks now run before any push. --- local/scripts/pre-push-checks.sh | 5 + local/scripts/verify-patch-content.py | 140 +++++++++++++++++++++++++- local/sources/relibc | 2 +- 3 files changed, 141 insertions(+), 6 deletions(-) diff --git a/local/scripts/pre-push-checks.sh b/local/scripts/pre-push-checks.sh index 57bdd951f8..b044b9ad58 100755 --- a/local/scripts/pre-push-checks.sh +++ b/local/scripts/pre-push-checks.sh @@ -77,6 +77,11 @@ run_check "verify-patch-content-action" \ "python3 local/scripts/verify-patch-content.py --report action" \ "Orphan-patch decision-tree (INTEGRATED/SUPERSEDED/etc.)" +# 3b. verify-patch-content --selftest (Phase 6.5: regression tests) +run_check "verify-patch-content-selftest" \ + "python3 local/scripts/verify-patch-content.py --selftest" \ + "Patch-content audit algorithm regression tests" + # 4. verify-collision-detection run_check "verify-collision-detection" \ "python3 local/scripts/verify-collision-detection.py" \ diff --git a/local/scripts/verify-patch-content.py b/local/scripts/verify-patch-content.py index 004bdf9ce0..38c49fd6ec 100755 --- a/local/scripts/verify-patch-content.py +++ b/local/scripts/verify-patch-content.py @@ -63,9 +63,14 @@ def extract_added_lines(text): return lines -def audit_component(component, fork_root): - """Audit a single component's patch preservation status.""" - patches_dir = os.path.join(REPO_ROOT, 'local/patches', component) +def audit_component(component, fork_root, patches_dir=None): + """Audit a single component's patch preservation status. + + patches_dir defaults to local/patches/; selftest passes a + temp dir to override. + """ + if patches_dir is None: + patches_dir = os.path.join(REPO_ROOT, 'local/patches', component) if not os.path.isdir(patches_dir): return None # component has no patches dir — skip if not os.path.isdir(fork_root): @@ -106,7 +111,7 @@ def audit_component(component, fork_root): return total, preserved, orphaned -def suggest_action_for_orphan(patch_name, target_path, comp): +def suggest_action_for_orphan(patch_name, target_path, comp, fork_dir=None): """For an orphan patch, suggest an action by inspecting the fork log for related work.
