- 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.
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]
- 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
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.
- also omitted all modules and classes that aren't expicitly public
- omitted 'Smallinteger' (small i), but it's still in schema
- omitted NullType-related items from types.__all__
- patched up a few tests to use sql.table and sql.column, other related.
- marked as unsupported for mssql all two-phase and nested transcation tests
- marked as unsupported for mssql various transactional/session tests which require two connections looking at uncommitted/external data at the same time (ms-sql cant handle it)
- put better explicit closeout step in unitofwork.py tests to appease ms-sqls hard locking
