delta/python-packages/sqlalchemy.git/test/engine/test_execute.py, branch pr/156

- rework the handle error on connect tests from test_parsconnect where

2014-12-10T17:11:59+00:00

they don't really belong into a new suite in test_execute

- control the module name of the exception here for py3k compat

2014-10-19T17:37:48+00:00

- Exception messages have been spiffed up a bit. The SQL statement

2014-10-17T23:37:45+00:00

and parameters are not displayed if None, reducing confusion for
error messages that weren't related to a statement.  The full
module and classname for the DBAPI-level exception is displayed,
making it clear that this is a wrapped DBAPI exception.  The
statement and parameters themselves are bounded within a bracketed
sections to better isolate them from the error message and from
each other.
fixes #3172

- adjustment for ref #3200 as we need an immutabledict() here so

2014-10-07T16:43:27+00:00

that union() can be called, in the case of a dialect that uses
execution options inside of initialize() (e.g. oursql)

- The execution options passed to an :class:`.Engine` either via

2014-10-06T22:23:42+00:00

:paramref:`.create_engine.execution_options` or
:meth:`.Engine.update_execution_options` are not passed to the
special :class:`.Connection` used to initialize the dialect
within the "first connect" event; dialects will usually
perform their own queries in this phase, and none of the
current available  options should be applied here.  In
particular, the "autocommit" option was causing an attempt to
autocommit within this initial connect which would fail with
an AttributeError due to the non-standard state of the
:class:`.Connection`.
fixes #3200

- Fixed bug where a "branched" connection, that is the kind you get

2014-09-26T20:25:26+00:00

when you call :meth:`.Connection.connect`, would not share transaction
status with the parent.  The architecture of branching has been tweaked
a bit so that the branched connection defers to the parent for
all transactional status and operations.
fixes #3190

- Fixed bug that affected generally the same classes of event

2014-09-18T21:49:07+00:00

as that of :ticket:`3199`, when the ``named=True`` parameter
would be used.  Some events would fail to register, and others
would not invoke the event arguments correctly, generally in the
case of when an event was "wrapped" for adaption in some other way.
The "named" mechanics have been rearranged to not interfere with
the argument signature expected by internal wrapper functions.
fixes #3197

- pep8 cleanup

2014-08-20T13:08:59+00:00

- The string keys that are used to determine the columns impacted

2014-08-15T00:00:35+00:00

for an INSERT or UPDATE are now sorted when they contribute towards
the "compiled cache" cache key.   These keys were previously not
deterministically ordered, meaning the same statement could be
cached multiple times on equivalent keys, costing both in terms of
memory as well as performance.
fixes #3165

- workaround removal of nested() in py3k
