to an instance will not drop into an EXISTS clause
and will compare foreign key columns instead.
- removed not-really-working use cases of comparing
a collection to an iterable. Use contains() to test
for collection membership.
- Further simplified SELECT compilation and its relationship
to result row processing.
- Direct execution of a union() construct will properly set up
result-row processing. [ticket:1194]
to use regular expressions and format strings, rather
than strptime/strftime, to generically support
pre-1900 dates, dates with microseconds. [ticket:968]
to 'scale'. 'length' is deprecated and is still accepted
with a warning. [ticket:827]
- The 'length' argument to MSInteger, MSBigInteger, MSTinyInteger,
MSSmallInteger and MSYear has been renamed to 'display_width'.
[ticket:827]
- mysql._Numeric now consumes 'unsigned' and 'zerofill' from
the given kw, so that the same kw can be passed along to Numeric
and allow the 'length' deprecation logic to still take effect
- added testlib.engines.all_dialects() to return a dialect for
every db module
- informix added to sqlalchemy.databases.__all__. Since other
"experimental" dbs like access and sybase are there, informix
should be as well.
- @unsupported now only accepts a single target and demands a reason
for not running the test.
- @exclude also demands an exclusion reason
- Greatly expanded @testing.requires.<feature>, eliminating many
decorators in the suite and signficantly easing integration of
multi-driver support.
- New ORM test base class, and a featureful base for mapped tests
- Usage of 'global' for shared setup going away, * imports as well
- added 2.4-style binops to util.Set on 2.3
- OrderedSets pickle on 2.3
- more lib/sqlalchemy set vs Set corrections
- fixed InstrumentedSet.discard for 2.3
- set, sorted compatibility for test suite
- added testing.fails_if decorator
- Importing testenv has no side effects- explicit functions provide similar behavior to the old immediate behavior of testbase
- testing.db has the configured db
- Fixed up the perf/* scripts
reconnect after its underlying connection is invalidated, without
needing to connect() again from the engine. This allows an ORM session
bound to a single Connection to not need a reconnect.
Open transactions on the Connection must be rolled back after an invalidation
of the underlying connection else an error is raised. Also fixed
bug where disconnect detect was not being called for cursor(), rollback(),
or commit().
process_result_value(), which automatically take advantage of the processing
of the underlying type. Ideal for using with Unicode or Pickletype.
TypeDecorator should now be the primary way to augment the behavior of any
existing type including other TypeDecorator subclasses such as PickleType.
When convert_unicode=True, this flag also defaults to `True`, and results in all
unicode conversion operations raising an exception when a non-unicode bytestring
is passed as a bind parameter. It is strongly advised that all unicode-aware
applications make proper use of Python unicode objects (i.e. u'hello' and
not 'hello').
e.g. select([x* 5]) produces "SELECT x * 5 AS anon_1".
This allows the labelname to be present in the cursor.description
which can then be appropriately matched to result-column processing
rules. (we can't reliably use positional tracking for result-column
matches since text() expressions may represent multiple columns).
- operator overloading is now controlled by TypeEngine objects - the
one built-in operator overload so far is String types overloading
'+' to be the string concatenation operator.
User-defined types can also define their own operator overloading
by overriding the adapt_operator(self, op) method.
- untyped bind parameters on the right side of a binary expression
will be assigned the type of the left side of the operation, to better
enable the appropriate bind parameter processing to take effect
[ticket:819]
sets (i.e. when no TypeEngine/String/Unicode type is even being used;
previously it was detecting DBAPI types and converting regardless).
should fix [ticket:800]
- fixed oracle out_parameters, likely broke in beta6
- fixed oracle _normalize_case for encoded names, gets unicode reflection test to work
- a few extra tests tweaked/unsupported for oracle
to TEXT/CLOB when no length is present now occurs *only* for an exact type
of String or Unicode with no arguments. If you use VARCHAR or NCHAR
(subclasses of String/Unicode) with no length, they will be interpreted
by the dialect as VARCHAR/NCHAR; no "magic" conversion happens there.
This is less surprising behavior and in particular this helps Oracle keep
string-based bind parameters as VARCHARs and not CLOBs [ticket:793].
