* - Fixed bug in :class:`.Connection` and pool where theMike Bayer2015-02-041-0/+10
| | | | | | | | | :meth:`.Connection.invalidate` method, or an invalidation due to a database disconnect, would fail if the ``isolation_level`` parameter had been used with :meth:`.Connection.execution_options`; the "finalizer" that resets the isolation level would be called on the no longer opened connection. fixes #3302
* - simplify the "noconnection" error handling, settingMike Bayer2014-12-081-2/+2
| | | | | | | _handle_dbapi_exception_noconnection() to only invoke in the case of raw_connection() in the constructor of Connection. in all other cases the Connection proceeds with _handle_dbapi_exception() including revalidate.
* - adjust _revalidate_connection() again such that we pass a _wrap=FalseMike Bayer2014-12-051-2/+2
| | | | | | | | | | to it, so that we say we will do the wrapping just once right here in _execute_context() / _execute_default(). An adjustment is made to _handle_dbapi_error() to not assume self.__connection in case we are already in an invalidated state further adjustment to 0639c199a547343d62134d2f233225fd2862ec45, 41e7253dee168b8c26c49, #3266

* - vastly improve the "safe close cursor" tests in test_reconnectMike Bayer2014-05-301-14/+57
| | | | | | | | | | | - Fixed bug which would occur if a DBAPI exception occurs when the engine first connects and does its initial checks, and the exception is not a disconnect exception, yet the cursor raises an error when we try to close it. In this case the real exception would be quashed as we tried to log the cursor close exception via the connection pool and failed, as we were trying to access the pool's logger in a way that is inappropriate in this very specific scenario. fixes #3063

* - A major improvement made to the mechanics by which the :class:`.Engine`Mike Bayer2014-03-221-6/+8
| | | | | | | | | | | | recycles the connection pool when a "disconnect" condition is detected; instead of discarding the pool and explicitly closing out connections, the pool is retained and a "generational" timestamp is updated to reflect the current time, thereby causing all existing connections to be recycled when they are next checked out. This greatly simplifies the recycle process, removes the need for "waking up" connect attempts waiting on the old pool and eliminates the race condition that many immediately-discarded "pool" objects could be created during the recycle operation. fixes #2985
* - remove informix dialect, moved out to ↵Mike Bayer2013-11-171-10/+0

* Dialect.initialize() is not called a second time if an :class:`.Engine`Mike Bayer2013-07-111-3/+31
| | | | | | is recreated, due to a disconnect error. This fixes a particular issue in the Oracle 8 dialect, but in general the dialect.initialize() phase should only be once per dialect. Also in 0.8.3. [ticket:2776]
* - replace most explicitly-named test objects called "Mock..." withMike Bayer2013-06-301-225/+218
| | | | | | | | | | | | actual mock objects from the mock library. I'd like to use mock for new tests so we might as well use it in obvious places. - use unittest.mock in py3.3 - changelog - add a note to README.unittests - add tests_require in setup.py - have tests import from sqlalchemy.testing.mock - apply usage of mock to one of the event tests. we can be using this approach all over the place.

* Improvements to Connection auto-invalidationMike Bayer2013-04-111-14/+122
| | | | | | | | | | | | | handling. If a non-disconnect error occurs, but leads to a delayed disconnect error within error handling (happens with MySQL), the disconnect condition is detected. The Connection can now also be closed when in an invalid state, meaning it will raise "closed" on next usage, and additionally the "close with result" feature will work even if the autorollback in an error handling routine fails and regardless of whether the condition is a disconnect or not.

* - [bug] Fixed bug whereby if a database restartMike Bayer2012-06-221-0/+27

* - [bug] Fixed bug whereby transaction.rollback()Mike Bayer2011-12-041-0/+21
| | | | | | | | | | | would throw an error on an invalidated connection if the transaction were a two-phase or savepoint transaction. For plain transactions, rollback() is a no-op if the connection is invalidated, so while it wasn't 100% clear if it should be a no-op, at least now the interface is consistent. [ticket:2317]

| | | | | | | | call are now wrapped in sqlalchemy.exc.StatementError, and the text of the SQL statement and repr() of params is included. This makes it easier to identify statement executions which fail before the DBAPI becomes involved. [ticket:2015]
* - add connection and cursor to is_disconnect(). We aren't using it yet,Mike Bayer2011-02-091-4/+35
| | | | | | | | | | | | | | | but we'd like to. Most DBAPIs don't give us anything we can do with it. Some research was done on psycopg2 and it still seems like they give us no adequate method (tried connection.closed, cursor.closed, connection.status). mxodbc claims their .closed attribute will work (but I am skeptical). - remove beahvior in pool that auto-invalidated a connection when the cursor failed to create. That's not the pool's job. we need the conn for the error logic. Can't get any tests to fail, curious why that behavior was there, guess we'll find out (or not). - add support for psycopg2 version detection. even though we have no use for it yet... - adjust one of the reconnect tests to work with oracle's horrendously slow connect speed
