* - remove .columns method on UpdateBase since a returning()Mike Bayer2016-02-103-11/+10
| | | | | | construct isn't intended to be used in SELECT queries directly - implement a direct system within CTE to detect UpdateBase and extract columns from returning directly
* - fix parenthesizationMike Bayer2016-02-103-16/+30
| | | | | - restore implicit returning to INSERT, UPDATE - tests from PG's docs
* - move out isinsert/isupdate/isdelete stateMike Bayer2016-02-103-39/+78

* - step 1 - add cte(), some docs, a test, get to the point whereMike Bayer2016-02-103-125/+171
| | | | we see that the "self.isupdate" thing is conflicting
* - add more documentation to MutableDict explainingMike Bayer2016-02-101-0/+12
| | | | | | that this structure is only intended to track additions and removals from the dictionary, not recursive tracking of embedded changes. fixes #3646.
* - don't drop the ts1/ts2 databases without seeing the primary DB,Mike Bayer2016-02-091-6/+21
| | | | | because we never log in on the ts1/ts2. races against other runs and erases their DBs
* - A refinement to the logic which adds columns to the resulting SQL whenMike Bayer2016-02-092-15/+33
| | | | | | | | | | | | | :meth:`.Query.distinct` is combined with :meth:`.Query.order_by` such that columns which are already present will not be added a second time, even if they are labeled with a different name. Regardless of this change, the extra columns added to the SQL have never been returned in the final result, so this change only impacts the string form of the statement as well as its behavior when used in a Core execution context. Additionally, columns are no longer added when the DISTINCT ON format is used, provided the query is not wrapped inside a subquery due to joined eager loading. fixes #3641
* - Testing reveals that we have *no* weak references to any cx_Oracle ↵Mike Bayer2016-02-081-9/+32
| | | | | | | | connections at all, yet cx_Oracle still has open sessions that cannot be killed until process dies. Oracle wins! Add a completely separate DB reaper script that runs after py.test is done.
* - use config-based test schemaMike Bayer2016-02-081-5/+5

* - attempt a different style of session killMike Bayer2016-02-081-1/+2
|
* - fully hyperlink the docstring for make_transientMike Bayer2016-02-082-12/+48
| | | | | | | | | - establish make_transient and make_transient_to_detached as special-use, advanced use only functions - list all conditions under make_transient() under which an attribute will not be loaded and establish that make_transient() does not attempt to load all attributes before detaching the object from its session, fixes #3640

* - add an impl for Enum to Oracle which has subclassing requirementsMike Bayer2016-02-041-0/+13
| | | | | | | on unicode. Enum would be better as a TypeDecorator at this point but then that becomes awkward with native enum types (Interval works that way, but we don't need the bind_processor for native interval...)

* | | - add changelog and migration notes for new Enum features,Mike Bayer2016-02-022-74/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fixes #3095, #3292 - reorganize enum constructor to again work with the MySQL ENUM type - add a new create_constraint flag to Enum to complement that of Boolean - reinstate the CHECK constraint tests for enum, these already fail /skip against the MySQL backend - simplify lookup rules in Enum, have them apply to all varieties of Enum equally
* | | - Initial implementation of support for PEP-435 enumerated typesAlex Grönholm2016-02-021-5/+72
| | | | | | | | | | | | within the Enum type.
* | | - Fixed issue where inadvertent use of the Python ``__contains__``Mike Bayer2016-02-022-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | override with a column expression (e.g. by using ``'x' in col``) would cause an endless loop in the case of an ARRAY type, as Python defers this to ``__getitem__`` access which never raises for this type. Overall, all use of ``__contains__`` now raises NotImplementedError. fixes #3642
* | | - put a retry in for PG database provisioning as it locksMike Bayer2016-01-291-1/+14

| | | | | | | | | | | | | | | | | | | | | removed; this has emitted a warning for many years and projects should be calling upon ``sqlalchemy.dialects.postgresql``. Engine URLs of the form ``postgres://`` will still continue to function, however.

* | | - revert the change first made in a6fe4dc, as we are now generalizingMike Bayer2016-01-282-14/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the warning here to all safe_reraise() cases in Python 2. - Revisiting :ticket:`2696`, first released in 1.0.10, which attempts to work around Python 2's lack of exception context reporting by emitting a warning for an exception that was interrupted by a second exception when attempting to roll back the already-failed transaction; this issue continues to occur for MySQL backends in conjunction with a savepoint that gets unexpectedly lost, which then causes a "no such savepoint" error when the rollback is attempted, obscuring what the original condition was. The approach has been generalized to the Core "safe reraise" function which takes place across the ORM and Core in any place that a transaction is being rolled back in response to an error which occurred trying to commit, including the context managers provided by :class:`.Session` and :class:`.Connection`, and taking place for operations such as a failure on "RELEASE SAVEPOINT". Previously, the fix was only in place for a specific path within the ORM flush/commit process; it now takes place for all transational context managers as well. fixes #2696
* | | - reinstate "dont set up integer index in keymap if we're on cexts",Mike Bayer2016-01-272-6/+11
| | | | | | | | | | | | | | | and this time also fix the cext itself to properly handle int vs. long on py2k
* | | Revert "- dont set up integer index in keymap if we're on cexts"Mike Bayer2016-01-271-10/+5
| | | | | | | | | | | | | | | | | | This reverts commit de0d144a395c31eb74084177df95a4858b830f88. Apparently the test suite is not using the cextensions correctly at the moment.

* | - rework ColumnCollection to no longer persist "all_col_set"; we don'tMike Bayer2016-01-261-20/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | need this collection except in the extend/update uses where we create it ad-hoc. simplifies pickling. Compatibility with 1.0 should be OK as ColumnColleciton uses __getstate__ in any case and the __setstate__ contract hasn't changed. - Fixed bug in :class:`.Table` metadata construct which appeared around the 0.9 series where adding columns to a :class:`.Table` that was unpickled would fail to correctly establish the :class:`.Column` within the 'c' collection, leading to issues in areas such as ORM configuration. This could impact use cases such as ``extend_existing`` and others. fixes #3632
* | - The workaround for right-nested joins on SQLite, where they are rewrittenMike Bayer2016-01-262-7/+14
| | | | | | | | | | | | | | | | | | | | as subqueries in order to work around SQLite's lack of support for this syntax, is lifted when SQLite version 3.7.16 or greater is detected. fixes #3634 - The workaround for SQLite's unexpected delivery of column names as ``tablename.columnname`` for some kinds of queries is now disabled when SQLite version 3.10.0 or greater is detected. fixes #3633
* | - add a new qualifier "native" vs. "dbapi" unicode to avoidMike Bayer2016-01-241-0/+5

* | - documenation updates to clarify specific SQLite versionsMike Bayer2016-01-211-2/+14
| | | | | | | | | | | | | | | | | | that have problems with right-nested joins and UNION column keys; references #3633 references #3634. backport from 1.1 to 0.9 announcing 1.1 as where these behaviors will be retired based on version-specific checks - fix test_resultset so that it passes when SQLite 3.10.0 is present, references #3633
* | - Added new parameter :paramref:`.orm.mapper.passive_deletes` toMike Bayer2016-01-202-1/+44
| | | | | | | | | | | | | | | | available mapper options. This allows a DELETE to proceed for a joined-table inheritance mapping against the base table only, while allowing for ON DELETE CASCADE to handle deleting the row from the subclass tables. fixes #2349
* | - The unsupported Sybase dialect now raises ``NotImplementedError``Mike Bayer2016-01-201-5/+1

* | Fix ArrayOfEnum's handling of empty arrays.pr/229Chase2016-01-191-1/+1
| | | | | | Prior to this change a value of `'{}'` would split into the list `['']`.
* | - the order in which _generate_backref() for different mappers is calledMike Bayer2016-01-191-1/+1
| | | | | | | | | | is random; therefore it may be called against the subclass mapper first, so need to check .concrete on both sides, references #3630
* | - calling str() on a core sql construct has been made more "friendly",Mike Bayer2016-01-196-2/+56
| | | | | | | | | | | | | | | | | | | | when the construct contains non-standard sql elements such as returning, array index operations, or dialect-specific or custom datatypes. a string is now returned in these cases rendering an approximation of the construct (typically the postgresql-style version of it) rather than raising an error. fixes #3631 - add within_group to top-level imports - add eq_ignore_whitespace to sqlalchemy.testing imports
