of ClassManager, and made it a private method on
_ClassInstrumentationAdapter. ClassManager's approach
handles the default task with fewer function calls which chops off
a few hundred calls from the pertinent profile tests.
Pass in the argument "label_length=<value>" to create_engine()
to adjust how many characters max will be present in dynamically
generated column labels, i.e. "somecolumn AS somelabel". Any
value less than 6 will result in a label of minimal size,
consiting of an underscore and a numeric counter.
The compiler uses the value of dialect.max_identifier_length
as a default. [ticket:1211]
- removed ANON_NAME regular expression, using string patterns now
- _generated_label() unicode subclass is used to indicate generated names
which are subject to truncation
- The internal notion of an "OID" or "ROWID" column has been
removed. It's basically not used by any dialect, and the
possibility of its usage with psycopg2's cursor.lastrowid
is basically gone now that INSERT..RETURNING is available.
- Removed "default_order_by()" method on all FromClause
objects.
- profile/compile/select test is 8 function calls over on buildbot 2.4 for some reason, will adjust after checking
the results of this commit
- 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
- 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__.
- 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
