- TODO: add sqlite to the standard alternate schema tests. a little tricky, because unlike CREATE SCHEMA, an ATTACH DATABASE won't survive a pool dispose...
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]
column mapping when generating a LIMIT/OFFSET subquery,
allows columns to map properly to result sets even
if long-name truncation kicks in [ticket:941]
- 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
to a collection-based attribute which already had pending changes
would generate incorrect history [ticket:922]
- fixed delete-orphan cascade bug whereby setting the same
object twice to a scalar attribute could log it as an orphan
[ticket:925]
- generative select.order_by(None) / group_by(None) was not managing to
reset order by/group by criterion, fixed [ticket:924]
the tree can now run the full suite of tests out of the box.
- Migrated most @supported to @fails_on, @fails_on_everything_but, or (last
resort) @unsupported. @fails_on revealed a slew of bogus test skippage,
which was corrected.
- Added @fails_on_everything_but. Yes, the first usage *was*
"fails_on_everything_but('postgres')". How did you guess!
- Migrated @supported in dialect/* to the new test-class attribute __only_on__.
- Test classes can also have __unsupported_on__ and __excluded_on__.
"unique identifier" mechanisms as everything else. This doesn't affect
user code, except any code that might have been hardcoded against the generated
names. Generated bind params now have the form "<paramname>_<num>",
whereas before only the second bind of the same name would have this form.
- bindparam() objects themselves can be used as keys for execute(), i.e.
statement.execute({bind1:'foo', bind2:'bar'})
- changed the various "literal" generation functions to use an anonymous
bind parameter. not much changes here except their labels now look
like ":param_1", ":param_2" instead of ":literal"
- from_obj keyword argument to select() can be a scalar or a list.
- cleanup within compiler visit_select(), column labeling
- is_select() removed from dialects, replaced with returns_rows_text(), returns_rows_compiled()
- should_autocommit() removed from dialects, replaced with should_autocommit_text() and
should_autocommit_compiled()
- typemap and column_labels collections removed from Compiler, replaced with single "result_map" collection.
- ResultProxy uses more succinct logic in combination with result_map to target columns
use "rowid" against the select itself (i.e. its just...'rowid', no table name).
seems to work OK but not sure if issues will arise
- fixes to oracle bind param stuff to account for recent removal of ClauseParameters object.
