- 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
Reasons for failures included an unhandled error code, erroneous sorting
assumptions, and a broken computation of the next insert ID in tests
Five failures remain.
This involved changes to the driver interface as well as the database
schemata. The most significantly altered queries were for article
selection and marking, which relied upon unusual features of SQLite.
Overall query efficiency should not be adversely affected (it may have
even imprved) in the common case, while very rare cases (not presently
triggered by any REST handlers) require more queries.
One notable benefit of these changes is that functions which query
articles can now have complete control over which columns are returned.
This has not, however, been implemented yet: symbolic column groups are
still used for now.
Note that PostgreSQL still fails many tests, but the test suite runs to
completion. Note also that one line of the Database class is not
covered; later changes will eventually make it easier to cover the line
in question.
