15029	Delegate to DB backends the task of detecting when different DATABASES item values point to different RDBMS test DBs	Ramiro Morales	nobody	"In r14696/r14822 we fixed  the ability to detect and handle without data loss database definitions that point to the same RDBMS database when setting up/tearing down tests.

The tuple of values used to distinguish among them contains (HOST, PORT ENGINE, NAME). In Oracle test setup all these values can be identical among two DATABASES item values but still point to different databases (actually tablespaces, in the Oracle nomenclature), even further, they usually will be the same when using a single Oracle installation. Shai also hinted about MS SQL possible needing more variables in the mix for similar reasons.

The patch attached to this ticket moves that to a method of !BaseDatabaseCreation so it can be customized by the backends that need this. This reduces again the number of test suite failures happening in Oracle (currently, tests that assume the ''default'' and ''other'' databases are mutually isolated do fail.)"		closed	Database layer (models, ORM)	dev		fixed			Accepted	1	0	0	0	0	0
