Hi folks, I'm not sure if this is the right place to ask really. I have some functional tests, using webtest, in which I make an engine and make a couple of session that get used in addition to the webtest app. I close the sessions in the tearDown method after each test.
Now that the number of functional tests is over about 100, they have started failing, but *only* when I run the whole mess together. Run file by file, they are all fine. The error I'm getting is pasted below. I'm running stock postgres on os x (installed from the universal binary, no special tweaking). I've tried changing pool_size to 20 and max_overflow to -1 but that doesn't seem to make a difference. Any clues would be lovely! thanks iain traceback: src/warp.test/warp/test/functional.py:70: in setUp self.init_db() src/warp.test/warp/test/functional.py:51: in init_db cls.engine.execute("drop owned by alimetrix") env/lib/python2.7/site-packages/sqlalchemy/engine/base.py:1990: in execute connection = self.contextual_connect(close_with_result=True) env/lib/python2.7/site-packages/sqlalchemy/engine/base.py:2039: in contextual_connect self._wrap_pool_connect(self.pool.connect, None), env/lib/python2.7/site-packages/sqlalchemy/engine/base.py:2078: in _wrap_pool_connect e, dialect, self) env/lib/python2.7/site-packages/sqlalchemy/engine/base.py:1405: in _handle_dbapi_exception_noconnection exc_info env/lib/python2.7/site-packages/sqlalchemy/util/compat.py:202: in raise_from_cause reraise(type(exception), exception, tb=exc_tb, cause=cause) env/lib/python2.7/site-packages/sqlalchemy/engine/base.py:2074: in _wrap_pool_connect return fn() env/lib/python2.7/site-packages/sqlalchemy/pool.py:376: in connect return _ConnectionFairy._checkout(self) env/lib/python2.7/site-packages/sqlalchemy/pool.py:713: in _checkout fairy = _ConnectionRecord.checkout(pool) env/lib/python2.7/site-packages/sqlalchemy/pool.py:480: in checkout rec = pool._do_get() env/lib/python2.7/site-packages/sqlalchemy/pool.py:1060: in _do_get self._dec_overflow() env/lib/python2.7/site-packages/sqlalchemy/util/langhelpers.py:60: in __exit__ compat.reraise(exc_type, exc_value, exc_tb) env/lib/python2.7/site-packages/sqlalchemy/pool.py:1057: in _do_get return self._create_connection() env/lib/python2.7/site-packages/sqlalchemy/pool.py:323: in _create_connection return _ConnectionRecord(self) env/lib/python2.7/site-packages/sqlalchemy/pool.py:449: in __init__ self.connection = self.__connect() env/lib/python2.7/site-packages/sqlalchemy/pool.py:607: in __connect connection = self.__pool._invoke_creator(self) env/lib/python2.7/site-packages/sqlalchemy/engine/strategies.py:97: in connect return dialect.connect(*cargs, **cparams) env/lib/python2.7/site-packages/sqlalchemy/engine/default.py:385: in connect return self.dbapi.connect(*cargs, **cparams) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ dsn = 'dbname=alimetrix_test user=alimetrix password=alimetrix host=localhost', database = 'alimetrix_test', user = 'alimetrix', password = 'alimetrix', host = 'localhost', port = None connection_factory = None, cursor_factory = None, async = False, kwargs = {}, items = [('dbname', 'alimetrix_test'), ('user', 'alimetrix'), ('password', 'alimetrix'), ('host', 'localhost')] k = 'host', v = 'localhost' def connect(dsn=None, database=None, user=None, password=None, host=None, port=None, connection_factory=None, cursor_factory=None, async=False, **kwargs): """ Create a new database connection.
