- renamed SessionTransaction autoflush to reentrant_flush to more clearly state its purpose
- added _enable_transaction_accounting, flag for Mike Bernson which disables the whole 0.5 transaction state management; the system depends on expiry on rollback in order to function.
- @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
- this branch changes query.values() to immediately return an iterator, adds a new "aliased" construct which will be the primary method to get at aliased columns when using values()
- tentative ORM versions of _join and _outerjoin are not yet public, would like to integrate with Query better (work continues in the branch)
- lots of fixes to expressions regarding cloning and correlation. Some apparent ORM bug-workarounds removed.
- to fix a recursion issue with anonymous identifiers, bind parameters generated against columns now just use the name of the column instead of the tablename_columnname label (plus the unique integer counter). this way expensive recursive schemes aren't needed for the anon identifier logic. This, as usual, impacted a ton of compiler unit tests which needed a search-n-replace for the new bind names.
- Part one of test suite fixes to run on 2.3
Lots of failures still around sets; sets.Set differs from __builtin__.set
particularly in the binops. We depend on set extensively now and may need to
provide a corrected sets.Set subclass on 2.3.
reference to the parent object so that the query
still has a parent to call against even if the
parent is only created (and otherwise dereferenced)
within the scope of a single expression [ticket:938]
- 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
that of regular relations. if passive_deletes flag (also just added)
is not set, a delete of the parent item will trigger a full load of
the child items so that they can be deleted or updated accordingly.
"attribute_names", a list of individual attribute keynames to be refreshed
or expired, allowing partial reloads of attributes on an already-loaded
instance.
- finally simplified the behavior of deferred attributes, deferred polymorphic
load, session.refresh, session.expire, mapper._postfetch to all use a single
codepath through query._get(), which now supports a list of individual attribute names
to be refreshed. the *one* exception still remaining is mapper._get_poly_select_loader(),
which may stay that way since its inline with an already processing load operation.
otherwise, query._get() is the single place that all "load this instance's row" operation
proceeds.
- cleanup all over the place
2. compiler names changed to be less verbose, unused classes removed.
3. Methods on Dialect which return compilers, schema generators, identifier preparers
have changed to direct class references, typically on the Dialect class itself
or optionally as attributes on an individual Dialect instance if conditional behavior is needed.
This takes away the need for Dialect subclasses to know how to instantiate these
objects, and also reduces method overhead by one call for each one.
4. as a result of 3., some internal signatures have changed for things like compiler() (now statement_compiler()), preparer(), etc., mostly in that the dialect needs to be passed explicitly as the first argument (since they are just class references now). The compiler() method on Engine and Connection is now also named statement_compiler(), but as before does not take the dialect as an argument.
5. changed _process_row function on RowProxy to be a class reference, cuts out 50K method calls from insertspeed.py
- flattened mapper calls in _instance() to operate directly
through a default MapperExtension
- more tests for ScopedSession, fixed [ticket:746]
- threadlocal engine propagates **kwargs through begin()
- moved 'identity_key' to be a classmethod on Session
- some docstrings
- merged r3229 from 0.3 branch to unconditonally quote schemaname in PG-reflected default
- name fixes in dynamic unit test
- fixups to ORM test fixture code
- fixup to dynamic realtions, test for autoflush session, delete-orphan
- made new dynamic_loader() function to create them
- removed old hasparent() call on AttributeHistory
