an existing table (such as a table that was already
reflected) using the 'useexisting=True' flag, which now
takes into account the arguments passed along with it.
- fixed one element of [ticket:910]
- refactored reflection test
as well as generative autocommit() method on select();
for statements which modify the database through some
user-defined means other than the usual INSERT/UPDATE/
DELETE etc., this flag will enable "autocommit" behavior
during execution if no transaction is in progress
[ticket:915]
- 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
reconnect after its underlying connection is invalidated, without
needing to connect() again from the engine. This allows an ORM session
bound to a single Connection to not need a reconnect.
Open transactions on the Connection must be rolled back after an invalidation
of the underlying connection else an error is raised. Also fixed
bug where disconnect detect was not being called for cursor(), rollback(),
or commit().
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__.
as the "schema" argument in a Table, will assume that this is the the
user's desired convention, and will explicitly set the "schema" argument
in foreign-key-related reflected tables, thus making them match only
with Table constructors that also use the explicit "schema" argument
(even though its the default schema).
In other words, SA assumes the user is being consistent in this usage.
sets (i.e. when no TypeEngine/String/Unicode type is even being used;
previously it was detecting DBAPI types and converting regardless).
should fix [ticket:800]
- fixed oracle out_parameters, likely broke in beta6
- fixed oracle _normalize_case for encoded names, gets unicode reflection test to work
- a few extra tests tweaked/unsupported for oracle
for contextual connection, unique_connection() for non-contextual.
- Pool use_threadlocal defaults to True, can be set to false at create_engine()
level with pool_threadlocal=False
- made all logger statements in pool conditional based on a flag calcualted once.
- chagned WeakValueDictionary() used for "threadlocal" pool to be a regular dict
referencing weakref objects. WVD had a lot of overhead, apparently. *CAUTION* -
im pretty confident about this change, as the threadlocal dict gets explicitly managed
anyway, tests pass with PG etc., but keep a close eye on this one regardless.
2. compiler names changed to be less verbose, unused classes removed.
3. Methods on Dialect which return compilers, schema generators, identifier preparers
have changed to direct class references, typically on the Dialect class itself
or optionally as attributes on an individual Dialect instance if conditional behavior is needed.
This takes away the need for Dialect subclasses to know how to instantiate these
objects, and also reduces method overhead by one call for each one.
4. as a result of 3., some internal signatures have changed for things like compiler() (now statement_compiler()), preparer(), etc., mostly in that the dialect needs to be passed explicitly as the first argument (since they are just class references now). The compiler() method on Engine and Connection is now also named statement_compiler(), but as before does not take the dialect as an argument.
5. changed _process_row function on RowProxy to be a class reference, cuts out 50K method calls from insertspeed.py
