- Trotted out util.pending_deprecation, replacing some 'TODO: deprecate's
- Big session docstring content edit fiesta
- session.py line length and whitespace non-fiesta
- @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.
- merge() uses the priamry key attributes on the object if _instance_key not present. so merging works for instances that dont have an instnace_key, will still issue UPDATE for existing rows.
- improved collection behavior for merge() - will remove elements from a destination collection that are not in the source.
- fixed naive set-mutation issue in Select._get_display_froms
- simplified fixtures.Base a bit
- removes everything to do with select_table, which remains as a keyword argument synonymous with
with_polymorphic=('*', select_table).
- all "polymorphic" selectables find their way to Query by way of _set_select_from() now, so that
all joins/aliasing/eager loads/etc. is handled consistently. Mapper has methods for producing
polymorphic selectables so that Query and eagerloaders alike can get to them.
- row aliasing simplified, so that they don't need to nest. they only need the source selectable
and adapt to whatever incoming columns they get.
- Query is more egalitarian about mappers/columns now. Still has a strong sense of "entity zero",
but also introduces new unpublished/experimental _values() method which sets up a columns-only query.
- Query.order_by() and Query.group_by() take *args now (also still take a list, will likely deprecate
in 0.5). May want to do this for select() as well.
- the existing "check for False discriminiator" "fix" was not working completely, added coverage
- orphan detection was broken when the target object was a subclass of the mapper with the orphaned
relation, fixed that too.
exactly synonymous with the "schema" keyword. Tables
can now be reflected with alternate "owner" attributes,
explicitly stated on the Table object or not using
"schema".
- all of the "magic" searching for synonyms, DBLINKs etc.
during table reflection
are disabled by default unless you specify
"oracle_resolve_synonyms=True" on the Table object.
Resolving synonyms necessarily leads to some messy
guessing which we'd rather leave off by default.
When the flag is set, tables and related tables
will be resolved against synonyms in all cases, meaning
if a synonym exists for a particular table, reflection
will use it when reflecting related tables. This is
stickier behavior than before which is why it's
off by default.
- session.refresh() and session.expire() raise an error when
called on instances which are not persistent within the session
- session._validate_persistent() properly raises an error for false check
- your cries have been heard: removing a pending item
from an attribute or collection with delete-orphan
expunges the item from the session; no FlushError is raised.
Note that if you session.save()'ed the pending item
explicitly, the attribute/collection removal still knocks
it out.
an existing table (such as a table that was already
reflected) using the 'useexisting=True' flag, which now
takes into account the arguments passed along with it.
- fixed one element of [ticket:910]
- refactored reflection test
and update() constructs which return a new object with
criterion joined to existing criterion via AND, just
like select().where().
- compile assertions use assertEquals()
- 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
- 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.
- 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
