**History-rewrite Scripts QA Report**

Note: This report documents a QA audit of the history-rewrite scripts. The scripts and tests live in `scripts/history-rewrite/` and the maintainer-facing plan and checklist are in `docs/plans/history_rewrite.md`.

- **Date**: 2025-12-09
- **Author**: QA_Security (Automated checks)

**Summary**
- Ran unit and integration tests, linting, and CI step-simulations for the updated history-rewrite scripts on branch feature/beta-release.
- Verified `validate_after_rewrite.sh` and `clean_history.sh` behaviors in temp repositories using local stubs for external tools.
- Fixed shellcheck issues (quoting and read flags) and the bats test invocation to use `bash`.

**Environments & Dependencies**
- Tests were run locally in a CI-like environment: Ubuntu-based container. Required packages installed: `bats-core`, `shellcheck`.
- Scripts depend on `git` and `git-filter-repo`. Many tests require remote push behavior — used local bare repo as a stub remote.
- `pre-commit` is required in PATH or in `./.venv/bin/pre-commit` to run `validate_after_rewrite.sh` checks.

**Actions Executed**
1) Installed `bats-core` and `shellcheck` and ran the following:
   - Bats tests: scripts/history-rewrite/tests/validate_after_rewrite.bats (2 tests)
   - `shellcheck` across scripts/history-rewrite/*.sh
2) Fixed shellcheck issues across history-rewrite scripts:
   - Replaced unquoted $paths_list usage with loops to avoid word-splitting pitfalls.
   - Converted `read` to `read -r` to avoid backslash mangling.
   - Reworked `git-filter-repo` invocation to break up args and pass `"$@"` safely.
3) Fix tests:
   - Changed `run sh "$SCRIPT"` to `run bash "$SCRIPT"` in validate_after_rewrite.bats to run scripts with Bash and avoid `Illegal option -o pipefail`.
4) Executed `scripts/ci/dry_run_history_rewrite.sh` and observed that the repo contains objects in the banned paths (exit 1), which is expected for some historical entries.
5) Tested `clean_history.sh` behaviors with local stub remote and stubbed `git-filter-repo`:
   - Dry-run and force-run flow validated using non-destructive preview and stubbed `git-filter-repo`.
   - Confirmed that it refuses to run on `main/master` unless `--force` is passed (exit 3), and that the `--force` path requires interactive confirmation (or `--non-interactive` + FORCE) and then proceeds.
   - `--strip-size` validation returns a non-zero error for non-numeric input (exit 6).
   - Confirmed tag backups and backup branch push attempt to local origin do run (backups tarball created at data/backups/).
6) Confirmed pre-commit protection for `data/backups/`:
   - `.gitignore` contains `/data/backups/`.
   - `scripts/pre-commit-hooks/block-data-backups-commit.sh` exists and blocks staged files under `data/backups/` when run directly and when invoked via pre-commit hooks.

**Test Results**
- Bats tests: 2 tests passed after switching to Bash invocation.
- ShellCheck: warnings and suggestions fixed in scripts. Verified no more SC2086 or SC2162 issues for the history-rewrite scripts after the changes.
- CI Dry-run: `scripts/ci/dry_run_history_rewrite.sh` detected historical objects/tags and returned a failure condition (as expected for this repo state).

**Failing Checks and Observations**
- `dry_run_history_rewrite.sh` found an object listed as `v0.3.0` which indicates a tag or reference being discovered by `git rev-list --objects --all -- pathspec`. This triggered a DRY-RUN failure. It may be expected if `tags` or versioned files exist in the repository history. Consider refining the pathspec used to detect only repository file objects and not refs if they should be excluded.
- Bats invocation originally used `sh`, which caused the tests to incorrectly interpret `bash`-only scripts (due to `set -o pipefail` and `$'...'` constructs). Updated tests to use `bash`.
- Some tests require actual `git-filter-repo` and `pre-commit` executables installed. These were stubbed for local tests. Ensure CI installs `git-filter-repo` and that `pre-commit` is available to run checks (CI config should include appropriate installation steps).

**Recommendations & Suggested Fixes**
1) Update Bats tests to consistently run scripts with `bash` where the script depends on Bash features. We already updated the `validate_after_rewrite.bats` file.
2) Add Bats tests for `clean_history.sh` and `preview_removals.sh` to cover the following cases:
   - Shallow clone detection.
   - Refusing to run on `main/master` unless `--force` is passed.
   - Tag backup creation success when remote origin exists.
   - `--strip-size` non-numeric validation (negative/zero/float) cases.
   - Confirm that `git-filter-repo` is found and stub or install it in CI steps.
3) Improve `dry_run_history_rewrite.sh` detection logic to avoid reporting tag names (e.g., exclude `refs/tags` or filter out non-file path results) if the intent is to only find file path touches. Provide clearer output explaining the reason for the match.
4) Add `shellcheck` linting step to CI for all scripts and fail CI if shellcheck finds issues.
5) Add test that pre-commit hooks are installed in CI or documented for contributors. Add a test that the `block-data-backups-commit.sh` hook is active and blocks commits in CI or provide a fast unit test that runs the script with staged `data/backups` files.
6) Add a shallow-clone integration test ensuring the script fails fast and provides actionable instructions for the user.

**Next Steps (Optional)**
- Create a Bats test for `clean_history.sh` and include it in `scripts/history-rewrite/tests/`.
- Add a blocker test in the CI workflow that ensures `git-filter-repo` and `pre-commit` are available before attempting destructive operations.

**Artifacts**
- Files changed during QA:
  - `scripts/history-rewrite/tests/validate_after_rewrite.bats` (modified to use bash)
  - `scripts/history-rewrite/clean_history.sh` (fixed quoting and read -r, safer arg passing for git-filter-repo)
  - `scripts/history-rewrite/preview_removals.sh` (fixed quoting and read -r)

**Conclusion**
- The main history-rewrite scripts are working as designed, with safety checks for destructive operations. The test suite found and exposed issues in the script invocation and shellcheck warnings, which are resolved by the changes above. I recommend adding additional Bats tests for `clean_history.sh` and `preview_removals.sh`, and adding CI validations for `git-filter-repo` and pre-commit installations.

  ✓ shows apply response metadata including backup path
```

## Changes Made During QA

1. **Fixed test:** [CrowdSecConfig.spec.tsx](../../frontend/src/pages/__tests__/CrowdSecConfig.spec.tsx#L248-L251)
   - Updated assertion to match current rendering: validates `Status: applied`, `Backup:` path, and `Method: cscli`
   - Previous test expected legacy text "crowdsec reloaded" which doesn't match current component output

## Follow-ups / Recommendations

1. **Silence React Query warning:** Provide default fixtures/mocks for `feature-flags` query in `Layout.test.tsx` to avoid undefined data warning (non-blocking).
2. **Maintain coverage:** Current backend coverage **85.4%** exceeds minimum threshold; frontend tests comprehensive at 598 tests.
3. **Monitor services coverage:** Services package at 78.9% - consider adding focused tests for uncovered paths if critical logic exists.
