Estimated code review effort🎯 4 (Complex) | ⏱️ ~50 minutes Rationale: The diff introduces substantial new functionality (async module with 4 new classes, type annotations across multiple existing classes, 5 new test files, and CI/CD setup). While many changes follow consistent patterns (uniform type annotations, parallel async/sync implementations), the heterogeneity—spanning new async logic, transaction management, CLI error handling, packaging configuration, and test structure—demands separate reasoning for each area. The async module alone contains dense, interrelated logic; reviews of type safety, async context management, and test coverage each require distinct attention. Poem

431-449: Bug:iter(Record([], []))raises TypeError for no‑result statementsThis breaks DDL/DML via query(). Use an empty iterator instead.

🧹 Nitpick comments (28)
records.egg-info/PKG-INFO (1)
1-79: ExcludePKG-INFOfrom VCS and align supported Python versions with CI.
PKG-INFOshould be build-only. Remove from the repo and add to .gitignore.- Classifiers list Python 3.7–3.12; ensure your CI matrix/tests match exactly and that tool versions (e.g., pytest) support those Pythons.

pyproject.toml, and CI matrices?build/lib/records.py (7)
178-196: Avoid O(n) re-iteration inRecordCollection.dataset.
len(list(self)),self[0], andself.all()cause multiple full iterations. Use a single fast existence check and iterate once.Apply this diff:

14-15: Avoid name shadowing with SQLAlchemyConnection.Module defines its own

18-20: Update to latest GitHub Actions versions.The
actions/setup-python@v4action is outdated and may not run on current GitHub-hosted runners.Update to v5:
- uses: actions/setup-python@v4 + uses: actions/setup-python@v5Apply this change at both lines 18 and 39.
Also applies to: 39-41
8-12: Add timeout protection for workflow jobs.Jobs without timeout configurations can hang indefinitely, consuming runner resources and delaying feedback.
Add timeouts to both jobs:
jobs: test: runs-on: ubuntu-latest + timeout-minutes: 30 strategy:build-and-publish: needs: test runs-on: ubuntu-latest + timeout-minutes: 15Also applies to: 31-33
22-25: Enable pip dependency caching to speed up CI.Caching pip dependencies reduces installation time and improves CI performance.
Add caching after the Python setup step:
- name: Set up Python ${{ matrix.python-version }} uses: actions/setup-python@v5 with: python-version: ${{ matrix.python-version }} + cache: 'pip'.github/workflows/test.yml (2)

test_enhancements_simple.py (1)
29-29: Prefer idiomatic boolean checks.Multiple lines use
== Trueor== Falsecomparisons. While functional, direct boolean evaluation is more Pythonic.For example, at line 29:
- assert record.active == True + assert record.activeSimilarly for lines 58, 62, 86, 93, and 121-124. Consider using
assert valuefor True checks andassert not valuefor False checks.Also applies to: 58-58, 62-62, 86-86, 93-93, 121-124
pyproject.toml (1)
27-27: Add Python 3.12 classifier and constrain pytest version.Python 3.12 is tested in CI workflows but missing from classifiers. Additionally, consider adding an upper bound to pytest to prevent breaking changes.
Add Python 3.12 to classifiers (already present at line 27, so this is fine). For pytest, consider:
test = [ - "pytest>=6.0", + "pytest>=6.0,<9.0", "pytest-cov", ]This provides stability while allowing minor version updates within the 8.x series.
Also applies to: 48-48, 56-56

27-27: Consider idiomatic boolean assertions.Multiple test assertions use
== Trueor== Falsecomparisons. While functional, pytest works better with direct boolean evaluation for clearer failure messages.For example:
- assert record.active == True + assert record.active- assert collection.pending == False + assert not collection.pendingThis pattern applies to lines 27, 89, 94, 153, 156, 161, 164, 168, 231, 235, 244, 248, 268, 271, and 274-276.

final_integration_test.py (4)
21-23: Assertion style (avoid == True)- assert db.open == True + assert db.open
80-82: Assertion style- assert records.isexception(ValueError()) == True - assert records.isexception(ValueError) == True - assert records.isexception("not an exception") == False + assert records.isexception(ValueError()) + assert records.isexception(ValueError) + assert not records.isexception("not an exception")
85-90: Do not useassert FalseRaise AssertionError explicitly.
- records.Database(None) # Should raise ValueError - assert False, "Should have raised ValueError" + records.Database(None) # Should raise ValueError + raise AssertionError("Should have raised ValueError")
161-165: Broad exception in test runnerCatching bare Exception makes failures opaque.
- except Exception as e: + except (AssertionError, RuntimeError, ValueError) as e: print(f"\n❌ Integration test failed: {e}") import traceback traceback.print_exc() return Falseasync_records.py (1)
115-133: Non-idiomatic async propertyasync @Property works but is unconventional; prefer an async method to avoid surprising API.

72-77: Tighten AttributeError chainingAvoid exposing KeyError details; suppress context.
- except KeyError as e: - raise AttributeError(e) + except KeyError as e: + raise AttributeError(str(e)) from None
310-315: Unused parameterinternalIf not needed, drop it; otherwise, document or use it.
- def get_table_names(self, internal: bool = False, **kwargs) -> List[str]: + def get_table_names(self, **kwargs) -> List[str]:

Non-blocking lint steps defeat their purpose.
The lint and mypy steps use || true to prevent failures, making them effectively informational only. This allows code quality issues to pass unchecked.

Python 3.8 incompatibility with latest pytest.
Python 3.8 support was dropped in pytest 8.4.2, but pyproject.toml specifies pytest>=6.0 without an upper bound, meaning the latest pytest will be installed by default. Additionally, Python 3.12 is in the test matrix but missing from the package classifiers in pyproject.toml (lines 22-27).
Update the Python version matrix to align with supported versions and add an upper bound for pytest if continuing to support Python 3.8:
- python-version: ['3.8', '3.9', '3.10', '3.11', '3.12']
+ python-version: ['3.9', '3.10', '3.11', '3.12']Or, if Python 3.8 support is required, pin pytest in pyproject.toml:

Python 3.8 incompatibility and workflow inconsistency.
Same issue as release.yml: pytest 8.4.2 dropped Python 3.8 support. Additionally, this workflow tests Python 3.8-3.11 while release.yml tests 3.8-3.12, creating inconsistent coverage.

Database.transaction definitions; the later overrides the earlier and loses the
open check and close_with_result=True behavior. Remove the duplicate method or
merge them so only one transaction method remains: ensure it checks self.open
and raises ResourceClosedError if closed, obtains conn via
self._engine.connect(), begins trans, wraps the connection with Connection(conn,
close_with_result=True), yields it, commits on success, rollbacks on exception,
and always closes conn in finally. Keep the original docstring and behavior and
