move FAQ to the docs, [ticket:2133]

2013-08-21T22:48:34+00:00

- apply an import refactoring to the ORM as well

2013-08-14T23:58:34+00:00

- rework the event system so that event modules load after their
targets, dependencies are reversed
- create an improved strategy lookup system for the ORM
- rework the ORM to have very few import cycles
- move out "importlater" to just util.dependency
- other tricks to cross-populate modules in as clear a way as possible

- assorted fixes raised by pypy 2.1beta2, but all of which are good

2013-08-02T00:25:56+00:00

ideas in general:
  - pypy2.1 w/ sqlite3 is the first DBAPI we're seeing returning
    unicode in cursor.description without being py3k.  add a new on-connect
    check for this, if we get back a u"", just don't do description decoding,
    should be OK for now.
  - the set tests in test_collection were assuming the two sets would be ordered
    the same when it tested pop(), can't really assume that.
  - test_serializer gets worse and worse, pickle is just not really viable here,
    ding out pypy
  - pypy2.1b2 seems to allow cursor.lastrowid to work (or we changed something?)
  - pool._threadconns.current() is a weakref, it can be None
  - another one of those logging.handlers imports

Fixed bug where :class:`.QueuePool` would lose the correct

checked out count if an existing pooled connection failed to reconnect
after an invalidate or recycle event.  Also in 0.8.3.
[ticket:2772]

- refactor pool a bit so that intent between ConnectionRecord/ConnectionFairy is clear;

2013-07-02T17:14:21+00:00

make sure that the DBAPI connection passed to the reset-on-return events/dialect hooks
is also a "fairy", so that dictionaries like "info" are available.  [ticket:2770]
- rework the execution_options system so that the dialect is given the job of making
any immediate adjustments based on a set event.  move the "isolation level" logic to use
this new system.   Also work things out so that even engine-level execution options
can be used for things like isolation level; the dialect attaches a connect-event
handler in this case to handle the task.
- to support this new system as well as further extensibiltiy of execution options
add events engine_connect(), set_connection_execution_options(), set_engine_execution_options()

Preserve reset_on_return when recreating a Pool.

2013-06-10T22:04:39+00:00

Added pool logging for "rollback-on-return" and the less used

2013-06-09T20:16:53+00:00

"commit-on-return".  This is enabled with the rest of pool
"debug" logging.
[ticket:2752]

a pass where we try to squash down as many list()/keys() combinations

2013-05-26T23:06:13+00:00

as possible

- the raw 2to3 run

2013-04-27T23:53:57+00:00

- went through examples/ and cleaned out excess list() calls

- remove all compat items that are pre-2.5 (hooray)

2013-03-09T22:26:16+00:00

- other cleanup
- don't need compat.decimal, that approach never panned out. hopefully
outside libs aren't pulling it in, they shouldn't be
