pytest play games with logging output [1]. [1]: https://github.com/pytest-dev/pytest/issues/5502 But this does not actually affect ClickHouse tests, the only reason is that the kazoo client is not stopped correctly without calling kazoo.client.KazooClient.stop(), and that's why you can see the following messages: <details> test_storage_rabbitmq/test.py::test_rabbitmq_big_message --- Logging error --- Traceback (most recent call last): File "/usr/local/lib/python3.8/dist-packages/kazoo/protocol/connection.py", line 179, in _socket_error_handling yield File "/usr/local/lib/python3.8/dist-packages/kazoo/protocol/connection.py", line 659, in _connect self._socket = self.handler.create_connection( File "/usr/local/lib/python3.8/dist-packages/kazoo/handlers/threading.py", line 178, in create_connection return utils.create_tcp_connection(socket, *args, **kwargs) File "/usr/local/lib/python3.8/dist-packages/kazoo/handlers/utils.py", line 265, in create_tcp_connection sock = module.create_connection(address, timeout_at) File "/usr/lib/python3.8/socket.py", line 808, in create_connection raise err File "/usr/lib/python3.8/socket.py", line 796, in create_connection sock.connect(sa) socket.timeout: timed out During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/local/lib/python3.8/dist-packages/kazoo/protocol/connection.py", line 579, in _connect_attempt read_timeout, connect_timeout = self._connect(host, hostip, port) File "/usr/local/lib/python3.8/dist-packages/kazoo/protocol/connection.py", line 659, in _connect self._socket = self.handler.create_connection( File "/usr/lib/python3.8/contextlib.py", line 131, in __exit__ self.gen.throw(type, value, traceback) File "/usr/local/lib/python3.8/dist-packages/kazoo/protocol/connection.py", line 182, in _socket_error_handling raise ConnectionDropped("socket connection error: %s" % (err,)) kazoo.exceptions.ConnectionDropped: socket connection error: None During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3.8/logging/__init__.py", line 1088, in emit stream.write(msg + self.terminator) ValueError: I/O operation on closed file.

This patch is an addition to the `logging.raiseExceptions=False` - #44618 Signed-off-by: Azat Khuzhin <a.khuzhin@semrush.com>
