- Each parameter is checked for type and normalized
- Interval strings are converted to DateInterval objects
- Timeouts can be specified as interval strings
- Most intervals can be null to signify infinity
- Driver classes are checked that they implement the correct interface
- Short driver names may be used, and are used by default
- Helpful errors messages are printed in case of erroneous configuration
Exporting is currently broken; this will be fixed in an upcoming commit
No testing has been performed yet, but changes are extensive enough to
warrant a commit. Of particular note:
- SQL states are enumerated in a separate trait to reduce duplication
- PDOStatement is now an abstract class to avoid duplication of
engine-specific error handling
- Error handling has been cleaned up somewhat
PDO does not adequately inform PostgreSQL of a parameter's type, so type
casts are required. Rather than adding these to each query manually, the
queries are instead processed to add type hints automatically.
Unfortunately the queries are processed rather naively; question-mark
characters in string constants, identifiers, regex patterns, or geometry
operators will break things spectacularly.
Tests for different drivers will have their own files, but all derive
from a common prototype test series where applicable, similar to the
existing arrangement for database function tests. However, the prototype
will reside with other test cases rather than in the library path. The
database function test series will hopefully be moved as well in time.
