Summary

TDD expected-fail tests proving bug #822 exists: CheckpointService.rollback_to_checkpoint() returns a successful RollbackResult but does not actually execute git reset --hard against the repository. The method constructs metadata but skips the real filesystem operation.

Tests Added

Behave scenarios (features/tdd_checkpoint_real_rollback.feature):

  • Rollback should restore modified file content to checkpoint state
  • Rollback should remove files added after checkpoint

Tags: @tdd_expected_fail @tdd_bug @tdd_bug_822

Robot Framework tests (robot/tdd_checkpoint_real_rollback.robot):

  • Mirrors both Behave scenarios using the Run Process + sentinel pattern with on_timeout=kill

Files Changed

Self-Review — PR #929

Reviewer: @brent.edwards (author self-review)
Review method: 4 parallel threads (TDD correctness, cross-cutting patterns, Robot compliance, PR metadata) + 2 fresh-eyes passes

Findings

P2:should-fix — @mock_only tag semantically incorrect

features/tdd_checkpoint_real_rollback.feature:1

The feature is tagged @mock_only, but the test creates real temporary git repos via subprocess, runs git init/git add/git commit, and asserts on real filesystem state. Per features/environment.py:554, @mock_only means "fully mocked services, no database." The test does real I/O — it is not mock-only by the documented definition. The practical effect (skip DB temp creation) is correct, but semantics are violated.

Remediation: Consider removing @mock_only or documenting that the tag means "no database needed" rather than "fully mocked."

P2:should-fix — _fail() return type should be NoReturn

robot/helper_tdd_checkpoint_real_rollback.py:52

The _fail function calls raise SystemExit(1) and never returns. The return type is -> None but should be -> NoReturn (from typing). PR #930's helper correctly uses -> NoReturn. Without NoReturn, Pyright cannot detect unreachable code after _fail() calls.

P3:nit — raise SystemExit(1) vs sys.exit(1) inconsistency

robot/helper_tdd_checkpoint_real_rollback.py:55

PR #930 and existing codebase helpers use sys.exit(1). This PR uses raise SystemExit(1). Functionally equivalent but inconsistent.

P3:nit — _fail prefixes "FAIL: " unlike PR #930

Minor formatting inconsistency in error output.

Correctness Verification

Tests correctly prove bug #822: CheckpointService.rollback_to_checkpoint() constructs metadata without calling git reset --hard. Tests assert on real filesystem state (file content, file existence) which remains unchanged after simulated rollback. Tests would correctly fail (triggering @tdd_expected_fail inversion) if the bug were actually fixed. Assertions are specific (exact content checks, not just return value checks).

Verdict

2 P2, 2 P3. Approve with comments — P2s should be addressed before merge.

Code Review Report — PR #929 (tdd/m6-checkpoint-real-rollback)

Reviewer: Automated code review (test coverage, test flaws, performance, bugs, security)
Scope: All code changes in tdd/m6-checkpoint-real-rollback branch + close connections to surrounding code
References: Issue #822 (bug), Issue #839 (TDD), docs/specification.md


Review Summary

The PR correctly implements TDD failing tests for bug #822 (checkpoint rollback is simulated). The tests are well-structured, follow the project's three-tag TDD convention, and exercise the right behavior. The Behave scenarios and Robot Framework tests properly prove the bug exists by asserting filesystem state after rollback. No security issues were found. A few issues were identified across multiple review cycles.


Findings by Severity

MEDIUM — Bugs

B1. Temp directory leak on Behave step failure

  • File: features/steps/tdd_checkpoint_real_rollback_steps.py:70-91
  • Issue: context.add_cleanup(_cleanup) is registered at line 91, after 6 _run_git() calls and other filesystem operations (lines 74-85) that could throw subprocess.CalledProcessError. If any of those operations fails, the tmpdir created at line 70 will never be cleaned up, leaking a temporary directory on disk.
  • Contrast: The Robot helper (helper_tdd_checkpoint_real_rollback.py) correctly uses try/finally for cleanup in both rollback_restores_content() and rollback_removes_added_files().
  • Fix: Move cleanup registration immediately after tempfile.mkdtemp():
tmpdir = tempfile.mkdtemp(prefix="tdd_checkpoint_822_")
context.workspace_dir = tmpdir

# Register cleanup early to avoid leaks if subsequent steps fail
def _cleanup() -> None:
    shutil.rmtree(tmpdir, ignore_errors=True)
context.add_cleanup(_cleanup)

# Initialise git repo
_run_git(["init"], cwd=tmpdir)
# ... rest of setup

MEDIUM — Documentation

D1. PR description lists non-existent file

  • PR body: Lists features/mocks/git_helpers.py as a changed file ("Shared run_git / get_head_sha helper utilities")
  • Reality: This file does not exist in the git diff (only 4 files changed) and does not exist anywhere in the repository. The _run_git() and _get_head_sha() helpers are defined inline in each file.
  • Impact: Misleads reviewers about the scope and factoring of the changes. The PR description should be updated to remove this entry.

LOW — Documentation

D2. PR description tag mismatch

  • PR body: Claims the feature file is tagged @tdd_expected_fail @tdd_bug @tdd_bug_822 @mock_only @tdd
  • Actual file (features/tdd_checkpoint_real_rollback.feature:1): Only has @tdd_expected_fail @tdd_bug @tdd_bug_822
  • Impact: Reviewers may assume @mock_only optimization and @tdd filter tag are present when they are not. The PR description should match the actual tags.

LOW — Test Flaws

T1. Missing on_timeout=kill in Robot test processes

  • File: robot/tdd_checkpoint_real_rollback.robot:21,30
  • Issue: Both Run Process calls use timeout=30s but omit on_timeout=kill. The established pattern in m5_e2e_verification.robot (18 occurrences) consistently uses on_timeout=kill alongside timeout=60s.
  • Impact: A hung subprocess receives SIGTERM (default) instead of SIGKILL. SIGTERM can be caught or ignored, potentially leaving temp directories behind and causing CI hangs.
  • Fix: Add on_timeout=kill to both Run Process calls:
${result}=    Run Process    ${PYTHON}    ${HELPER}    rollback-restores-content    cwd=${WORKSPACE}    timeout=30s    on_timeout=kill

T2. Missing @mock_only tag on feature file

  • File: features/tdd_checkpoint_real_rollback.feature:1
  • Issue: Both scenarios exercise CheckpointService() instantiated without repository or plan_lifecycle_service (fully in-memory, zero database I/O). The @mock_only tag would skip unnecessary per-scenario temp database file creation in features/environment.py (lines 554-567). No other TDD feature file uses @mock_only either, so this is consistent, but the optimization applies here.
  • Impact: Minor performance overhead per scenario (~0.5ms + temp file I/O). No functional impact.

T3. RollbackResult return value not asserted

  • File: features/steps/tdd_checkpoint_real_rollback_steps.py:137
  • Issue: step_invoke_rollback stores context.rollback_result but no "Then" step verifies properties of the RollbackResult object. The current simulated implementation returns restored_files_count=1 and changed_paths=["restored:<sha>"] regardless of actual filesystem state. An assertion like assert context.rollback_result.restored_files_count > 0 would catch discrepancies between the result metadata and actual behavior.
  • Note: The critical behavior (filesystem state) IS tested. This is supplementary coverage that would strengthen the TDD test when the fix is implemented — the fix should return accurate counts/paths in the result.

INFORMATIONAL — Code Quality

Q1. Duplicated helper functions across Behave and Robot files

  • Files: features/steps/tdd_checkpoint_real_rollback_steps.py:47-59 and robot/helper_tdd_checkpoint_real_rollback.py:66-78
  • Issue: _run_git() and _get_head_sha() are duplicated verbatim (identical implementations). No shared git helper module exists in the codebase — this is consistent with the existing pattern where each file defines its own helpers.
  • Consideration: As more TDD tests for git-based features are added (e.g., the fix for #822 will add more tests), a shared module under features/mocks/git_helpers.py could reduce maintenance burden. This is not blocking.

Positive Observations

  • The three-tag TDD system (@tdd_expected_fail @tdd_bug @tdd_bug_822) is correctly applied
  • Both Behave and Robot Framework tests cover the two primary git reset --hard behaviors (file reversion + file removal)
  • Test isolation is solid: unique temp directories per test, proper cleanup in Robot finally blocks
  • The test correctly sets up register_sandbox() with the workspace path and create_checkpoint() with the git SHA, compatible with the eventual fix implementation
  • The ULID plan ID 01JBG822CHKPT000PXAN000000 validates correctly against the ULID_PATTERN
  • All subprocess calls use list arguments (no shell injection), check=True, and timeouts
  • No security issues found

Verdict

No blocking issues. The 1 medium-severity bug (B1: cleanup ordering) is a resource leak that would only manifest on step failure and is unlikely to cause CI problems in practice. However, the fix is trivial (reorder 3 lines) and follows the same pattern the Robot helper already uses correctly. The remaining items are low-severity or informational.

Recommend addressing B1 and D1 before merge; the rest are at the author's discretion.

[B1/MEDIUM] Cleanup registration is too late. If any of the _run_git() calls on lines 74-82 or _get_head_sha() on line 85 throws subprocess.CalledProcessError, the tmpdir from line 70 will leak.

Move context.add_cleanup(_cleanup) immediately after tempfile.mkdtemp() (before line 73). The Robot helper gets this right with try/finally.

This would strengthen the TDD test for the future fix, which should return accurate metadata.

**[T3/LOW]** `context.rollback_result` is stored here but never asserted on. Consider adding a Then step like: ```python @then("the rollback result should indicate success") def step_assert_result(context): assert context.rollback_result is not None assert context.rollback_result.from_checkpoint_id == context.checkpoint.checkpoint_id ``` This would strengthen the TDD test for the future fix, which should return accurate metadata.

Code Review Report — PR #929 (tdd/m6-checkpoint-real-rollback)

Reviewer: OpenCode automated review (test coverage, test flaws, performance, bugs, security)
Scope: All code changes in tdd/m6-checkpoint-real-rollback branch + close connections to surrounding code
References: Issue #822 (bug), Issue #839 (TDD), docs/specification.md, CONTRIBUTING.md
Method: 3 full review cycles across all categories (bugs, test flaws, security, performance, code quality) until no new findings emerged
Commit reviewed: ed124436


Executive Summary

The PR correctly implements TDD failing tests for bug #822 (checkpoint rollback is simulated). The tests are well-structured, follow the project's mandatory three-tag TDD convention (@tdd_expected_fail @tdd_bug @tdd_bug_822), and correctly prove the bug exists by asserting real filesystem state after rollback. The Behave scenarios and Robot Framework tests both verify that CheckpointService.rollback_to_checkpoint() does not execute git reset --hard — files modified after the checkpoint remain unchanged.

All previously raised findings (B1, T1, D1, D2, self-review items) have been addressed in the current commit. Two new low-severity findings and one informational observation were identified across 3 review cycles. No critical, high, or medium-severity issues found. No security vulnerabilities. No performance concerns.


Findings by Severity

LOW — Bug / Resource Leak

L1. Robot helper _create_workspace() can leak temp directory on internal failure

  • File: robot/helper_tdd_checkpoint_real_rollback.py:84-100
  • Category: Bug / Resource Leak
  • Issue: This is the Robot-side analog of CoreRasurae's B1 finding (which was fixed for the Behave side). The _create_workspace() function calls tempfile.mkdtemp() on line 86, then executes 6 operations (git init, git config ×2, write_text, git add, git commit) that can all raise subprocess.CalledProcessError or OSError. If any of these throw, the exception propagates out of _create_workspace(), meaning the caller's tmpdir = _create_workspace() assignment never completes. The caller's try/finally block (which would do shutil.rmtree(tmpdir, ...)) is never entered, leaking the temp directory.
  • Contrast: The Behave side registers context.add_cleanup() immediately after mkdtemp() (B1 fix), ensuring cleanup even if subsequent operations fail. The Robot helper lacks this defensive pattern.
  • Impact: Low in practice — git init failures are rare, leaked directories are small (~4KB), and CI environments are ephemeral. But the fix is trivial.
  • Fix:
def _create_workspace() -> str:
    tmpdir = tempfile.mkdtemp(prefix="tdd_checkpoint_822_robot_")
    try:
        _run_git(["init"], cwd=tmpdir)
        _run_git(["config", "user.email", "test@example.com"], cwd=tmpdir)
        _run_git(["config", "user.name", "Test"], cwd=tmpdir)
        tracked_path = os.path.join(tmpdir, _TRACKED_FILENAME)
        Path(tracked_path).write_text(_INITIAL_CONTENT)
        _run_git(["add", _TRACKED_FILENAME], cwd=tmpdir)
        _run_git(["commit", "-m", "Initial commit"], cwd=tmpdir)
    except Exception:
        shutil.rmtree(tmpdir, ignore_errors=True)
        raise
    return tmpdir

LOW — Test Design / Robustness

L2. Robot tdd_expected_fail_listener does not distinguish infrastructure failures from expected bug failures

  • File: robot/tdd_expected_fail_listener.py:34-48 (surrounding code)

  • Category: Test Design / Robustness

  • Issue: The Behave apply_tdd_inversion() (features/environment.py:170-185) includes a guard that skips inversion when a step fails with a non-AssertionError exception — correctly treating CalledProcessError, ImportError, PermissionError, etc. as infrastructure problems that must propagate. The Robot listener lacks this guard and inverts any FAIL to PASS indiscriminately.

    For the new tests specifically: if helper_tdd_checkpoint_real_rollback.py crashes during workspace setup (e.g., git not installed, import failure, permission error), the Robot test would silently pass instead of reporting the infrastructure failure. The exit code from the crash (non-zero) triggers Should Be Equal As Integers failure, which the listener inverts to PASS.

  • Impact: Low — this is a pre-existing design limitation affecting all Robot TDD tests, not introduced by this PR. The risk is that broken CI infrastructure goes undetected for Robot TDD tests specifically.

  • Note: No simple mitigation exists within the scope of these tests. The listener would need to be enhanced to inspect failure context (e.g., a convention where helpers print a "reached assertion phase" marker that the test verifies via a non-TDD-tagged keyword). This is a framework improvement suggestion, not a blocking concern for this PR.


INFORMATIONAL — Code Quality

I1. git init without --initial-branch may produce warning on git 2.28+

  • Files: features/steps/tdd_checkpoint_real_rollback_steps.py:80, robot/helper_tdd_checkpoint_real_rollback.py:88
  • Issue: _run_git(["init"], cwd=tmpdir) on git 2.28+ may log a hint about init.defaultBranch to stderr. The warning is captured by capture_output=True and has zero functional impact (tests don't depend on branch names, git init still exits 0).
  • Suppression (optional): _run_git(["init", "--initial-branch=main"], cwd=tmpdir) or _run_git(["config", "init.defaultBranch", "main"], cwd=tmpdir) before init.

Previously Raised Findings — Status

T3RollbackResult not asserted LOW @CoreRasurae Deferred — reasonable, will add with bug fix
Q1 — Duplicated helpers INFO @CoreRasurae Deferred — consistent with codebase pattern
Self-review: NoReturn type P2 @brent.edwards FIXED
Self-review: sys.exit vs SystemExit P3 @brent.edwards FIXED

Specification Compliance

Verified against docs/specification.md:

  • Sandbox model (§Execution Workspace): Rollback mechanism for git-checkout resources is "Git reset/checkout" — the tests correctly assert that this mechanism is NOT being executed
  • Checkpointing in Execute (§Checkpointing): Rollback should restore filesystem state to checkpoint — the tests verify this is not happening
  • Safety Profile (§Safety Profile): require_checkpoints: true is the default — the checkpoint creation flow in the tests is consistent with the production path
  • Rollback Tiers (§Correction Safety): Full decision-level rollback requires checkpointing enabled + sandboxable resources — the test setup provides both

CONTRIBUTING.md Compliance

  • TDD Bug Fix Workflow followed (TDD issue #839 → test branch → PR)
  • Three-tag system correctly applied (@tdd_expected_fail @tdd_bug @tdd_bug_822)
  • Branch naming convention: tdd/m6-checkpoint-real-rollback
  • Commit message convention: test(plan): TDD failing tests for checkpoint real rollback (bug #822)
  • PR closes TDD issue #839 (not the bug issue #822 — correct per workflow)

Positive Observations

  1. Correct bug capture: Tests prove the exact bug described in #822rollback_to_checkpoint() returns a RollbackResult but skips git reset --hard
  2. Forward-compatible setup: register_sandbox(plan_id, workspace_dir) + create_checkpoint(sandbox_ref=sha) correctly provide both the WHERE (workspace path) and WHAT (commit SHA) needed for the eventual fix
  3. Strong test isolation: Unique temp directories per test, proper cleanup (Behave: context.add_cleanup; Robot: try/finally)
  4. No false positives/negatives possible: Explicit content modification + commit makes the assertion deterministic
  5. Clear assertion messages: Include bug reference, expected/actual values, and explanation of why the failure proves the bug
  6. Secure subprocess handling: List arguments (no shell injection), check=True, capture_output=True, 30s timeouts, on_timeout=kill
  7. Valid ULID: 01JBG822CHKPT000PXAN000000 passes ULID_PATTERN regex validation (verified programmatically)
  8. Previous review findings properly addressed: B1, T1, D1, D2, and self-review items all fixed in current commit

Verdict

No blocking issues. The PR is well-implemented and ready for merge. The two new low-severity findings (L1: Robot temp dir leak, L2: listener infrastructure masking) are at the author's discretion to address. L1 has a trivial 4-line fix; L2 is a pre-existing framework limitation.

[L1/LOW — Resource Leak] This function has the same structural issue that CoreRasurae caught as B1 on the Behave side: if any operation after mkdtemp() throws (e.g., git init fails with CalledProcessError), the temp directory leaks because the caller's try/finally never starts (tmpdir is never assigned in caller scope).

The Behave side was fixed by registering context.add_cleanup() immediately after mkdtemp(). The equivalent fix here:

def _create_workspace() -> str:
    tmpdir = tempfile.mkdtemp(prefix="tdd_checkpoint_822_robot_")
    try:
        _run_git(["init"], cwd=tmpdir)

Fixed integration test failures — 3eecb790

The 10 failing tests were all caused by subprocess timeout issues under CI parallel load (32 concurrent processes). The failures showed -15 != 0 (SIGTERM) and -9 != 0 (SIGKILL from on_timeout=kill).

Our TDD checkpoint test itself passed fine — the failures were in unrelated test suites whose Run Process calls either:

  1. Lacked on_timeout=kill, causing SIGTERM (-15) instead of clean SIGKILL (-9)
  2. Had timeouts too low for CI under heavy parallel load (30s/60s)

Fix applied across entire Robot test suite (56 files)

  • Added on_timeout=kill to every Run Process call that had a timeout= but no on_timeout= — prevents hanging processes and ensures clean kill semantics
  • Increased all timeouts to 120s — prevents premature kills during heavy CI parallelism (migrations alone can take 30-60s under load)
  • Fixed both explicit timeout=30s/timeout=60s and timeout=${TIMEOUT} variable-based patterns
