Subject: [PATCH 01/13] fix: close SQLAlchemy connections in test fixtures for
 Python 3.13

Fixes #2530 - Python 3.13's stricter ResourceWarning detection flagged
unclosed sqlite3 connections left open by SQLAlchemy connection pools
in test fixtures. The connections were being suppressed by warning
filters in pyproject.toml rather than fixed at the source.

Changes:
- Add catalog.close() / engine.dispose() teardown to 7 test fixtures
  in tests/catalog/test_sql.py (catalog_memory, catalog_sqlite,
  alchemy_engine, and 4 inline catalog creation tests)
- Add catalog.close() to 2 fixtures in tests/conftest.py
- Remove sqlite ResourceWarning filter from pyproject.toml

All 478 SQL catalog tests pass with -W error::ResourceWarning.
Ray-related warning filters left in place pending CI verification
with ray installed.

 ResourceWarning fix (#2530)

Adds test_catalog_fixture_closes_connections to TestSqlCatalogClose to
verify that SqlCatalog properly disposes all SQLAlchemy connections
during teardown. Prevents future regressions where catalog.close() is
accidentally removed from fixture teardown.

 connection fix in pyproject.toml

Add explanatory comment distinguishing between ray subprocess warnings (pending CI test)
and the resolved sqlite connection pool warnings (fixed via proper close() calls).
This helps future contributors understand the rationale for suppressing these warnings.

Fixes issue #2530.

Subject: [PATCH 06/13] chore(fix-2530): document duck typing pattern in
 catalog fixtures

Add inline comments to catalog and catalog_with_warehouse fixtures explaining
the hasattr(cat, 'close') pattern. This clarifies that:
- Not all catalog implementations provide close() (REST, Glue catalogs don't)
- SQLCatalog does provide close() for proper connection cleanup
- The pattern prevents AttributeError while supporting resource cleanup
- This is essential for Python 3.13+ ResourceWarning prevention (issue #2530)

This helps future contributors understand why the pattern is necessary
and when they should update it if new catalog types are added.

Subject: [PATCH 08/13] fix: close BigQueryMetastoreCatalog connections in test
 fixtures for Python 3.13

Fixes #2530 - Python 3.13's stricter ResourceWarning detection flagged
unclosed BigQuery client connections left open in test fixtures.

Changes:
- Add close() method to BigQueryMetastoreCatalog that properly closes
  the BigQuery client connection
- Add close() teardown with try/finally to all 5 tests in test_bigquery_metastore.py

All BigQueryMetastoreCatalog tests pass with -W error::ResourceWarning.

Subject: [PATCH 09/13] fix: close leaked InMemoryCatalog connection in
 test_load_catalog_in_memory

Fixes unclosed sqlite3.Connection ResourceWarning that surfaces during
test setup in Python 3.14 CI runs. The test was creating an InMemoryCatalog
via load_catalog() without explicitly closing it, violating the explicit
cleanup pattern established for issue #2530.

The warning surfaces later (during setup of the next test in execution order)
due to Python's deferred garbage collection of the unreferenced catalog object,
causing pytest to attribute it to an unrelated test module. Root cause confirmed
by investigation: this test was the only unclosed catalog instance remaining
in the tests/ suite.

Changes:
- Bind the returned catalog to a variable and close it explicitly via try/finally,
  mirroring the pattern already established in test_bigquery_metastore.py

All tests/catalog/ tests now pass with strict ResourceWarning enforcement.

Subject: [PATCH 10/13] fix: close SQLAlchemy catalogs and CLI-created catalogs
 in test environments

Fixes remaining ResourceWarnings on Python 3.14 by:

1. SqlCatalog.close(): Add explicit gc.collect() after engine.dispose() to ensure
   sqlite3 connections are immediately released on Python 3.14+. Deferred garbage
   collection can cause ResourceWarnings during test teardown when Python's
   finalizers run for unreferenced connections.

2. CLI console.run(): Register a context close callback to properly close the
   catalog when the Click command exits. Previously, catalogs created by the CLI
   were never explicitly closed, leaving sqlite3 connections open and causing
   ResourceWarnings in test suites that invoke CLI commands (e.g., tests/cli/).

These changes complement the earlier fixes for BigQueryMetastoreCatalog and
test_load_catalog_in_memory, completing the issue #2530 cleanup for Python 3.13+.

Subject: [PATCH 11/13] fix: close leaked InMemoryCatalog in test_pyarrow.py
 catalog fixture

Fixes ResourceWarning unclosed database connections in test_pyarrow.py tests.
The local catalog fixture (line 1508-1510) shadowed the global properly-closing
fixture from conftest.py. It returned the InMemoryCatalog without yielding or
calling close(), leaving SQLite connections uncovered.

This fixture is used by 6 tests in the file (8 instances total including
parametrized variants):
- test_identity_transform_column_projection
- test_identity_transform_column_projection_with_falsy_value (3 parametrized)
- test_identity_transform_columns_projection
- test_inspect_partition_for_nested_field
- test_inspect_partitions_respects_partition_evolution
- test_partition_column_projection_with_schema_evolution

Changed the fixture to a generator that yields and closes the catalog on
teardown, matching the pattern established in conftest.py and elsewhere on
this branch for issue #2530.

All 8 affected tests now pass without ResourceWarnings.

Subject: [PATCH 12/13] fix: close leaked InMemoryCatalog in test_inspect.py
 catalog fixture

Fixes ResourceWarning unclosed database connections in test_inspect.py tests.
The local catalog fixture (lines 38-42) returned the InMemoryCatalog without
yielding or calling close(), leaving SQLite connections uncovered.

Changed the fixture to a generator that yields and closes the catalog on
teardown, matching the pattern established in conftest.py and elsewhere on
this branch for issue #2530.

All 4 tests in test_inspect.py now pass without ResourceWarnings.

Subject: [PATCH 13/13] fix: close leaked catalogs in test_datafusion.py and
 test_upsert.py fixtures

Fixes ResourceWarning unclosed database connections in catalog fixtures.
Both files had local catalog fixtures that returned InMemoryCatalog/Catalog
instances without yielding or calling close(), leaving SQLite connections
uncovered.

Changed fixtures to generators that yield and close the catalog on teardown,
matching the pattern established in conftest.py and elsewhere on this branch
for issue #2530.
