From bdc2ccd6a314f1dc9b778bcf823d9db7af44b5c3 Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Fri, 8 May 2026 07:08:42 +0000 Subject: [PATCH 1/4] feat(invariants): implement Invariant data model and database schema This PR implements the Invariant data model and database schema for the v3.2.0 milestone. The Invariant feature enables the system to define, store, and manage invariant rules that can be evaluated against system state. - Alembic migration m3_001_invariants_table creates the invariants table with columns: id (UUID), description (text), created_at (timestamp), is_active (bool, default True), with index on is_active for efficiency - SQLAlchemy ORM InvariantModel in cleveragents.infrastructure.database.models.InvariantModel - M3 merge migration to resolve Alembic head conflict - BDD Behave scenarios (10 test cases) in features/invariant_model.feature - Robot Framework integration tests in robot/invariant_model.robot - Updated CHANGELOG.md and CONTRIBUTORS.md - Restored status-check CI aggregation job ISSUES CLOSED: #8524 --- CHANGELOG.md | 11 + CONTRIBUTORS.md | 1 + features/invariant_model.feature | 59 +++++ features/steps/invariant_model_steps.py | 233 ++++++++++++++++++ robot/helper_invariant_model.py | 188 ++++++++++++++ robot/invariant_model.robot | 63 +++++ .../versions/m3_001_invariants_table.py | 45 ++++ .../m3_002_merge_invariants_and_a5_006.py | 29 +++ .../infrastructure/database/models.py | 33 +++ 9 files changed, 662 insertions(+) create mode 100644 features/invariant_model.feature create mode 100644 features/steps/invariant_model_steps.py create mode 100644 robot/helper_invariant_model.py create mode 100644 robot/invariant_model.robot create mode 100644 src/cleveragents/infrastructure/database/migrations/versions/m3_001_invariants_table.py create mode 100644 src/cleveragents/infrastructure/database/migrations/versions/m3_002_merge_invariants_and_a5_006.py diff --git a/CHANGELOG.md b/CHANGELOG.md index 2468a0029..de9c852f3 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -968,6 +968,17 @@ uko-oo:Class` triple emission in `PythonAnalyzer._extract_class()` so that ### Added +- **Invariant Data Model and Database Schema** (#8524): Implemented the + `Invariant` SQLAlchemy ORM model in + `cleveragents.infrastructure.database.models.InvariantModel` with fields + `id (UUID)`, `description (text)`, `created_at (timestamp)`, and + `is_active (bool, default True)`.

#11091 / issue #7527): introduced `SandboxDirsCache` to track filesystem paths of sandbox-created directories by plan_id, wired automatic invalidation into all cleanup/purge methods (`cleanup_all`, `cleanup_abandoned`, `clear_sandbox_dirs_cache`, `_cleanup_on_exit_handler`), and added BDD test coverage. * HAL 9000 has contributed the CleanupService sandbox cache invalidation fix (PR #8257 / issue #7527): `_purge_sandboxes()` now invalidates the internal `_sandbox_dirs_cache` after deleting stale directories so that a subsequent `scan()` call on the same instance re-reads the filesystem instead of returning already-deleted paths as stale items. * HAL 9000 has contributed the LSP subprocess cleanup fix (#10597): added a defensive ``_process = None`` reset before ``subprocess.Popen()`` in ``StdioTransport.start()`` to prevent orphaned child processes and file descriptor leaks when ``subprocess.Popen()`` fails during initialization. +* HAL 9000 has contributed the Invariant Data
