* SQLite dialect - support relection from affinitypr/65Erich Blume2014-02-031-11/+36
| | | | | | | | | | | | | | | | | | | | | | SQLite allows column types that aren't technically understood in sqlite by using 'data affinity', which is an algorithm for converting column types in to some sort of useful type that can be stored and retrieved from the db. Unfortunatly, this breaks reflection since we (previously) expected a sqlite db to reflect column types that we permit in the `ischema_names` for that dialect. This patch changes the logic for 'unknown' column types during reflection to instead run through SQLite's data affinity algorithm, and assigns appropriate types from that. It also expands the matching for column type to include column types with spaces (strongly discouraged but allowed by sqlite) and also completely empty column types (in which case the NullType is assigned, which sqlite will treat as a Blob - or rather, Blob is treated as NullType). These changes mean that SQLite will never raise an error for an unknown type during reflection - there will always be some 'useful' type returned, which follows the spirit of SQLite (accomodation before sanity!).

* - Added new test coverage for so-called "down adaptions" of SQL types,Mike Bayer2014-01-222-8/+10
| | | | | | | | | | | where a more specific type is adapted to a more generic one - this use case is needed by some third party tools such as ``sqlacodegen``. The specific cases that needed repair within this test suite were that of :class:`.mysql.ENUM` being downcast into a :class:`.types.Enum`, and that of SQLite date types being cast into generic date types. The ``adapt()`` method needed to become more specific here to counteract the removal of a "catch all" ``**kwargs`` collection on the base :class:`.TypeEngine` class that was removed in 0.9.

| | | | | | | | | | | | | | | | | | | | | type such as "charset" and "collation". While MySQL wants all character- based CAST calls to use the CHAR type, we now create a real CHAR object at CAST time and copy over all the parameters it has, so that an expression like ``cast(x, mysql.TEXT(charset='utf8'))`` will render ``CAST(t.col AS CHAR CHARACTER SET utf8)``. - Added new "unicode returns" detection to the MySQL dialect and to the default dialect system overall, such that any dialect can add extra "tests" to the on-first-connect "does this DBAPI return unicode directly?" detection. In this case, we are adding a check specifically against the "utf8" encoding with an explicit "utf8_bin" collation type (after checking that this collation is available) to test for some buggy unicode behavior observed with MySQLdb version 1.2.3. While MySQLdb has resolved this issue as of 1.2.4, the check here should guard against regressions. The change also allows the "unicode" checks to log in the engine logs, which was not previously the case. [ticket:2906]
