- broke up adapter chaining in eagerload, erroneous "wrapping" in row_decorator. column_property() subqueries are now affected only by the ORMAdapter for that mapper. fixes [ticket:1037], and may possibly impact some of [ticket:949]
- @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
- With declarative, joined table inheritance mappers use a slightly relaxed
function to create the "inherit condition" to the parent
table, so that other foreign keys to not-yet-declared
Table objects don't trigger an error.
FROM clauses, such as select().select_from(text("sometext"))
[ticket:1014]
- removed _TextFromClause; _TextClause just adds necessary FromClause descriptors
at the class level
- 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.
as values by default, meaning case([(x==y, "foo")]) will
interpret "foo" as a bound value, not a SQL expression.
use text(expr) for literal SQL expressions in this case.
For the criterion itself, these may be literal strings
only if the "value" keyword is present, otherwise SA
will force explicit usage of either text() or literal().
ahead of the tablename in all column expressions as well
as when generating column labels. This prevents cross-
schema name collisions in all cases [ticket:999]
- the "use_schema" argument to compiler.visit_column() is removed. It uses
schema in all cases now.
- added a new test to the PG dialect to test roundtrip insert/update/delete/select
statements with full schema qualification
and have no FROM themselves. These are typically
used in a scalar context, i.e. SELECT x, (SELECT x WHERE y)
FROM table. Requires explicit correlate() call.
an OID column if it only contained one selectable element, due to missing return in _proxy_column()
- visit_column() calls itself to render a primary key col being used as the interpretation of the oid col instead of relying upon broken partial logic
and update() constructs which return a new object with
criterion joined to existing criterion via AND, just
like select().where().
- compile assertions use assertEquals()
other tests to more specific modules
- added "now()" as a generic function; on SQLite and
Oracle compiles as "CURRENT_TIMESTAMP"; "now()"
on all others [ticket:943]
now concatenate the wildcard operator with the given
operand in SQL, i.e. "'%' || <bindparam>" in all cases,
accept text('something') operands properly [ticket:962]
- cast() accepts text('something') and other non-literal
operands properly [ticket:962]
