postgresql - Ignore/reconnect for closed connection in pool -


i have problem pool.acquire() , closed connection in pool. setting on pg server set connection timeout 120 second. when use pool.acquire() raise error because connection closed:

sleep 150 traceback (most recent call last):   file "test.py", line 21, in <module>     loop.run_until_complete(test_select())   file "/usr/local/cellar/python3/3.5.1/frameworks/python.framework/versions/3.5/lib/python3.5/asyncio/base_events.py", line 337, in run_until_complete     return future.result()   file "/usr/local/cellar/python3/3.5.1/frameworks/python.framework/versions/3.5/lib/python3.5/asyncio/futures.py", line 274, in result     raise self._exception   file "/usr/local/cellar/python3/3.5.1/frameworks/python.framework/versions/3.5/lib/python3.5/asyncio/tasks.py", line 239, in _step     result = coro.send(none)   file "test.py", line 10, in test_select async pool.acquire() conn:   file "/usr/local/lib/python3.5/site-packages/aiopg/utils.py", line 116, in __aenter__     self._conn = yield self._coro   file "/usr/local/lib/python3.5/site-packages/aiopg/pool.py", line 170, in _acquire     assert not conn.closed, conn assertionerror: <aiopg.connection.connection object @ 0x106f7df98>

and code

import asyncio import aiopg  dsn = 'dbname=dbname user=user password=password host=127.0.0.1' async def test_select():     async aiopg.create_pool(dsn) pool:         print("sleep 150")         await asyncio.sleep(150)         async pool.acquire() conn:             async conn.cursor() cur:                 await cur.execute("select 1")                 ret = []                 async row in cur:                     ret.append(row)                 assert ret == [(1,)]     print("all done")   loop = asyncio.get_event_loop() loop.run_until_complete(test_select())

how solve problem. thanks!

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
