* Fix memory leak issue in ConfigDBConnector. (sonic-net#655) #### Why I did it Fix memory leak issue in ConfigDBConnector: [chassis] Too many open files error and unable to connect to redis socket error sonic-net/sonic-buildimage#10870 The reason of this issue is DBConnector::pubsub() will return a pointer, and following code call this method but never release the returned pointer: ``` void ConfigDBConnector_Native::db_connect(string db_name, bool wait_for_init, bool retry_on) { m_db_name = db_name; m_key_separator = m_table_name_separator = get_db_separator(db_name); SonicV2Connector_Native::connect(m_db_name, retry_on); if (wait_for_init) { auto& client = get_redis_client(m_db_name); auto pubsub = client.pubsub(); <== this pointer not delete later. ``` Also change DBConnector::pubsub() to deprecated for none SWIG scenario. #### How I did it Change DBConnector::pubsub() to return a smart pointer. #### How to verify it Pass all test case. Run following code in python and validate there is no epoll and socket leak: ``` import gc from swsscommon import swsscommon config_db = swsscommon.ConfigDBConnector_Native() config_db.connect() config_db.connect() config_db.connect() gc.collect() ``` #### Which release branch to backport (provide reason below if selected) <!-- - Note we only backport fixes to a release branch, *not* features! - Please also provide a reason for the backporting below. - e.g. - [x] 202006 --> - [ ] 201811 - [ ] 201911 - [ ] 202006 - [ ] 202012 - [ ] 202106 - [x] 202111 #### Description for the changelog Fix epoll and socket resurce leak issue: [chassis] Too many open files error and unable to connect to redis socket error sonic-net/sonic-buildimage#10870 #### Link to config_db schema for YANG module changes #### A picture of a cute animal (not mandatory but encouraged) Co-authored-by: liuh-80 <azureuser@liuh-dev-vm-02.5fg3zjdzj2xezlx1yazx5oxkzd.hx.internal.cloudapp.net> * Transfer organization from Azure to sonic-net (sonic-net#656) Transfer organization from Azure to sonic-net * Add docker-mux related table names (sonic-net#627) This PR is to add table name definitions for database entries used by docker mux processes.
