Anssi Kääriäinen 1893467784 Fixed #19274 -- Made db connection creation overridable in subclasses ... Connection creation was done in db backend ._cursor() call. This included taking a new connection if needed, initializing the session state for the new connection and finally creating the connection. To allow easier modifying of these steps in subclasses (for example to support connection pools) the _cursor() now calls get_new_connection() and init_connection_state() if there isn't an existing connection. This was done for all non-gis core backends. In addition the parameters used for taking a connection are now created by get_connection_params(). We should also do the same for gis backends and encourage 3rd party backends to use the same pattern. The pattern is not enforced in code, and as the backends are private API this will not be required by documentation either.		2012-11-27 19:47:19 +02:00
