Background

Found during review of PR #803. This is a pre-existing bug, not introduced by that PR.

Description

AutomationProfileRepository.upsert() and delete() never call session.close() when using auto_commit mode. By contrast, SessionRepository correctly uses finally: if self._auto_commit: db_session.close(). This inconsistency means AutomationProfileRepository leaks database sessions over time.

Expected Behavior

All repository methods that open sessions in auto_commit mode should close them in a finally block, consistent with the pattern established in SessionRepository.

Acceptance Criteria

  • AutomationProfileRepository.upsert() closes sessions in finally block
  • AutomationProfileRepository.delete() closes sessions in finally block
  • Pattern is consistent with SessionRepository
  • Unit test verifies session cleanup
  • nox passes with coverage >= 97%

PM Triage — Day 37

Triaged and classified:

  • Milestone: v3.5.0 (M6 — autonomy hardening, persistence reliability)
  • Priority: High (resource leak, impacts long-running operations)
  • Assignee: @CoreRasurae (Python persistence expertise)
  • Points: 2 (small scope — add finally: session.close() following existing SessionRepository pattern)

TDD counterpart creation deferred — this is a straightforward pattern consistency fix. A TDD counterpart will be created if the fix proves more complex than the 2-line pattern match suggests.

Assigned to @CoreRasurae for bug fix based on developer expertise (persistence layer — Luis has session management expertise). Priority escalated from High to Critical per policy: all bugs are Critical. This bug is top priority per project policy — bugs always take precedence over feature work.

TDD workflow initiated for this bug:

  • Created TDD issue #1092 to write a tagged test that captures this bug.
  • Dependency link added: this issue is blocked by #1092.
  • Once #1092 is merged to master, the bug fix assignee should create the bugfix branch and implement the fix.
  • The fix must remove the @tdd_expected_fail tag from the test so it runs normally.

Planning Agent — Discussion Review

TDD workflow confirmed. Assignment to @CoreRasurae for the session leak fix is correct.

Same TDD deferral pattern as #988 and #989: Day 37 triage suggested deferring TDD ("straightforward pattern consistency fix"), but TDD issue #1092 was correctly created later. To be clear for the record: the TDD workflow is never optional for bugs, regardless of perceived fix complexity. Per CONTRIBUTING.md §Bug Fix Workflow: "All bug fixes follow a mandatory Test-Driven Development (TDD) workflow." No exceptions.

The 2-point estimate is correct — adding finally: session.close() following the existing SessionRepository pattern is small, well-scoped work.

Load concern: @CoreRasurae now has #988, #987, #992, #991, #993, #990, #986 assigned (7 bugs). While these are individually small (2–3 points each), the aggregate load is ~17 points of bug work. This is manageable if the TDD tests land promptly, but I am flagging it for awareness.

No disputes on scope or priority.

Implementation Notes — Bug Fix

Design Decision

Followed the exact pattern already established by SessionRepository — both upsert() and delete() in AutomationProfileRepository now wrap their session usage in try/finally blocks that call session.close() when self._auto_commit is true.

Changes Made

  1. src/cleveragents/infrastructure/database/repositories.pyAutomationProfileRepository.upsert(): wrapped the commit+return logic in a try block, added finally: if self._auto_commit: session.close() after the existing commit call. Same pattern applied to delete().
  2. features/tdd_automation_profile_session_leak.feature — Removed @tdd_expected_fail tag from all 4 TDD scenarios. The tests now run as normal regression guards. Tags @tdd_issue and @tdd_issue_987 remain permanently per project policy.
  3. CHANGELOG.md — Added unreleased entry for the fix.

Verification

  • All 12,701 BDD scenarios pass (0 failures)
  • Pyright: 0 errors, 0 warnings
  • Ruff lint: clean
  • Coverage: 97% (meets threshold)
  • The 4 TDD scenarios from issue #1092 now pass without the expected-fail inversion

The fix adds finally: if self._auto_commit: session.close() blocks to all four public methods in AutomationProfileRepository (get_by_name(), list_all(), upsert(), delete()), matching the SessionRepository pattern. 8 Behave BDD regression scenarios cover success and error paths for all methods.

The fix adds finally: if self._auto_commit: session.close() blocks to all four public session-creating methods in AutomationProfileRepository (get_by_name(), list_all(), upsert(), delete()), matching the established SessionRepository pattern. 8 BDD regression scenarios verify both success and error paths for all methods. All CI checks passed.
