* - Mysqlconnector as of version 2.0, probably as a side effect ofMike Bayer2014-10-121-6/+40
| | | | | | | | | | | | | | | | the python 3 merge, now does not expect percent signs (e.g. as used as the modulus operator and others) to be doubled, even when using the "pyformat" bound parameter format (this change is not documented by Mysqlconnector). The dialect now checks for py2k and for mysqlconnector less than version 2.0 when detecting if the modulus operator should be rendered as ``%%`` or ``%``. - Unicode SQL is now passed for MySQLconnector version 2.0 and above; for Py2k and MySQL < 2.0, strings are encoded. Note that mysqlconnector as of 2.0.1 appears to have a bug with unicode DDL on py2k, so the tests here are skipping until we observe it's fixed. - take out profiling on mysqlconnector, callcounts vary too much with its current development speed

* | Reflect unique constraints when reflecting a Table objectJohannes Erdfelt2014-09-171-1/+2
|/ | | | | | | | | | | | | | | Calls to reflect a table did not create any UniqueConstraint objects. The reflection core made no calls to get_unique_constraints and as a result, the sqlite dialect would never reflect any unique constraints. MySQL transparently converts unique constraints into unique indexes, but SQLAlchemy would reflect those as an Index object and as a UniqueConstraint. The reflection core will now deduplicate the unique constraints. PostgreSQL would reflect unique constraints as an Index object and as a UniqueConstraint object. The reflection core will now deduplicate the unique indexes.

* - MySQL boolean symbols "true", "false" work again. 0.9's changeMike Bayer2014-09-051-0/+12
| | | | | | | | | | | in :ticket:`2682` disallowed the MySQL dialect from making use of the "true" and "false" symbols in the context of "IS" / "IS NOT", but MySQL supports this syntax even though it has no boolean type. MySQL remains "non native boolean", but the :func:`.true` and :func:`.false` symbols again produce the keywords "true" and "false", so that an expression like ``column.is_(true())`` again works on MySQL. fixes #3186

* - The MySQL dialect will now disable :meth:`.ConnectionEvents.handle_error`Mike Bayer2014-07-251-3/+6
| | | | | | | | | | events from firing for those statements which it uses internally to detect if a table exists or not. This is achieved using an execution option ``skip_user_error_events`` that disables the handle error event for the scope of that execution. In this way, user code that rewrites exceptions doesn't need to worry about the MySQL dialect or other dialects that occasionally need to catch SQLAlchemy specific exceptions.

* - Fixed bug which prevented MySQLdb-based dialects (e.g.Mike Bayer2014-02-031-0/+1
| | | | | | | | | | pymysql) from working in Py3K, where a check for "connection charset" would fail due to Py3K's more strict value comparison rules. The call in question wasn't taking the database version into account in any case as the server version was still None at that point, so the method overall has been simplified to rely upon connection.character_set_name().

| | | | | | | | | | | 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]

|/ | | | | | | | | | Python ``Decimal`` via string is now configurable. The flag ``decimal_return_scale`` is now supported by all :class:`.Numeric` and :class:`.Float` types, which will ensure this many digits are taken from the native floating point value when it is converted to string. If not present, the type will make use of the value of ``.scale``, if the type supports this setting and it is non-None. Otherwise the original default length of 10 is used. [ticket:2867]

In 0.8, the keywords will remain ignored but a warning is emitted. Additionally, the ``match`` keyword now raises a :class:`.CompileError` on 0.9 and emits a warning on 0.8; this keyword is not only silently ignored by MySQL but also breaks the ON UPDATE/ON DELETE options. To use a :class:`.ForeignKeyConstraint` that does not render or renders differently on MySQL, use a custom compilation option. An example of this usage has been added to the documentation, see :ref:`mysql_foreign_keys`. [ticket:2721] [ticket:2839]
