ORM events but also engine events, where the usual logic of
"de duplicating" a redundant call to :func:`.event.listen`
with the same arguments would fail, for those events where the
listener function is wrapped. An assertion would be hit within
registry.py. This assertion has now been integrated into the
deduplication check, with the added bonus of a simpler means
of checking deduplication across the board.
fixes#3199
kept separate from Postgresql's ON COMMIT for now even though ON COMMIT
is in the SQL standard; the option is still very specific to temp tables
and we eventually would provide a more first class temporary table
feature.
- oracle can apparently do get_temp_table_names() too, so implement that,
fix its get_table_names(), and add it to #3204. fixes#3204 again.
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.
:meth:`.Inspector.get_temp_view_names`; currently, only the
SQLite dialect supports these methods. The return of temporary
table and view names has been **removed** from SQLite's version
of :meth:`.Inspector.get_table_names` and
:meth:`.Inspector.get_view_names`; other database backends cannot
support this information (such as MySQL), and the scope of operation
is different in that the tables can be local to a session and
typically aren't supported in remote schemas.
fixes#3204
The sqlite get_unique_constraints() implementation did not do a union
against the sqlite_temp_master table like other code does. This could
result in an exception being raised if get_unique_constraints() was
called against a temporary table.
- reestablish the "bootstrap" system of loading the test runners
in testing/plugin; using the updated approach we just came up with for
alembic. Coverage should be fixed now when running either py.test or
nose. fixes#3196
- upgrade tox.ini and start using a .coveragerc file
primaryjoin contained functions, while at the same time remote_side
was specified; the warning would suggest setting "remote side".
It now only emits if remote_side isn't present.
fixes#3194
thrown off during a collection replace event, if the
reorder_on_append flag were set to True. The fix ensures that the
ordering list only impacts the list that is explicitly associated
with the object.
fixes#3191
unify everything.
- create a new layer of separation between the "from order bys" and "column order bys",
so that an OVER doesn't ORDER BY a label in the same columns clause
- identify another issue with polymorphic for ref #3148, match on label
keys rather than the objects
and :meth:`.AttributeEvents.dispose_collection`, which track when
a collection is first associated with an instance and when it is
replaced. These handlers supersede the :meth:`.collection.linker`
annotation. The old hook remains supported through an event adapter.
- https://readthedocs.org/projects/sqlalchemy/downloads/epub/latest/ renders with the full template which is unreadable on e-readers
- in the makefile the template-variable mako_layout is set for target: epub which makes mako use only the base layout.
- this is the more elegant solution as proposed to #133
