This allows starting and stopping separately each protocol server
without restarting ClickHouse.
This also allows adding or removing `listen_host` entries, which
start and stops servers for all enabled ports.
When stopping a server, the listening socket is immediately closed
(and available for another server).
Protocols with persistent connections try to wait for any currently
running query to finish before closing the connection, but idle
connection are closed quickly (depending on how often the protocol
is polled).
An extra ProfileEvent is added, `MainConfigLoads`, it is
incremented every time the configuration is reloaded. This helps
when trying to assess whether the new configuration was applied.
Which logs all the info about LogIn, LogOut and LogIn Failure events.
Additional info that is logged:
- User name
- event type (LogIn, LogOut, LoginFailure)
- Event date\time\time with microseconds
- authentication type (same as for IDENTIFIED BY of CREATE USER statement)
- array of active settings profiles upon login
- array of active roles upon login
- array of changed settings with corresponding values
- client address and port
- interface (TCP\HTTP\MySQL\PostgreSQL, etc.)
- client info (name, version info)
- optional LoginFailure reason text message.
Added some tests to verify that events are properly saved with all necessary info via following interfaces:
- TCP
- HTTP
- MySQL
Known limitations
- Not tested against named HTTP sessions, PostgreSQL and gRPC, hence those are not guaranteed to work 100% properly.
* client query kind is not set for mysql and postgresql
* Update MySQLHandler.cpp
* Update PostgreSQLHandler.cpp
