* Update sqlite3, dbm.sqlite3 and tests to CPython 3.14.2
* Add skip decorators for failing sqlite3 tests
Skip tests that fail due to unimplemented features or behavior differences:
- _iterdump not implemented (test_dump.py)
- Unraisable exception handling not implemented (test_hooks.py, test_userfunctions.py)
- Keyword-only arguments not supported for various methods
- Autocommit behavior differences (test_transactions.py)
- TransactionTests skipped due to timeout parameter type issue
- Various error message differences (test_dbapi.py)
- SQLITE_DBCONFIG constants not implemented
- Row and Connection signature inspection issues
All tests now pass with 95 skipped out of 493 total tests.
* Change @unittest.skip to @unittest.expectedFailure per code review
- Convert @unittest.skip decorators to @unittest.expectedFailure for tests that fail without panic/hang
- Keep @unittest.skip only for TransactionTests class (setUp fails with timeout=0 int type)
* fixup
* Fix sqlite3 Connection initialization check
Add proper __init__ validation for sqlite3.Connection to ensure base class
__init__ is called before using connection methods. This fixes the
test_connection_constructor_call_check test case.
Changes:
- Modified Connection.py_new to detect subclassing
- For base Connection class, initialization happens immediately in py_new
- For subclassed Connection, db is initialized as None
- Added __init__ method that performs actual database initialization
- Updated _db_lock error message to match CPython: 'Base Connection.__init__ not called.'
This ensures CPython compatibility where attempting to use a Connection
subclass instance without calling the base __init__ raises ProgrammingError.
* use Initializer trait
Add proper __init__ validation for sqlite3.Cursor to ensure base class
__init__ is called before using cursor methods. This fixes the
test_cursor_constructor_call_check test case.
Changes:
- Modified Cursor to initialize with inner=None in py_new
- Added explicit __init__ method that sets up CursorInner
- Updated close() method to check for uninitialized state
- Changed error message to match CPython: 'Base Cursor.__init__ not called.'
This ensures CPython compatibility where attempting to use a Cursor
instance without calling the base __init__ raises ProgrammingError.
