* Fixed bug where list instrumentation would fail to represent aMike Bayer2013-08-201-3/+8
| | | | | | | | setslice of ``[0:0]`` correctly, which in particular could occur when using ``insert(0, item)`` with the association proxy. Due to some quirk in Python collections, the issue was much more likely with Python 3 rather than 2. Also in 0.8.3, 0.7.11. [ticket:2807]

* - apply an import refactoring to the ORM as wellMike Bayer2013-08-143-10/+11
| | | | | | | | | - 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
* - A large refactoring of the ``sqlalchemy.sql`` package has reorganizedMike Bayer2013-08-123-32/+20
| | | | | | | | | | | | | | | | | | | | | | the import structure of many core modules. ``sqlalchemy.schema`` and ``sqlalchemy.types`` remain in the top-level package, but are now just lists of names that pull from within ``sqlalchemy.sql``. Their implementations are now broken out among ``sqlalchemy.sql.type_api``, ``sqlalchemy.sql.sqltypes``, ``sqlalchemy.sql.schema`` and ``sqlalchemy.sql.ddl``, the last of which was moved from ``sqlalchemy.engine``. ``sqlalchemy.sql.expression`` is also a namespace now which pulls implementations mostly from ``sqlalchemy.sql.elements``, ``sqlalchemy.sql.selectable``, and ``sqlalchemy.sql.dml``. Most of the "factory" functions used to create SQL expression objects have been moved to classmethods or constructors, which are exposed in ``sqlalchemy.sql.expression`` using a programmatic system. Care has been taken such that all the original import namespaces remain intact and there should be no impact on any existing applications. The rationale here was to break out these very large modules into smaller ones, provide more manageable lists of function names, to greatly reduce "import cycles" and clarify the up-front importing of names, and to remove the need for redundant functions and documentation throughout the expression package.
* - The :meth:`.Operators.notin_` operator added in 0.8 now properlyMike Bayer2013-08-071-0/+11
| | | | | produces the negation of the expression "IN" returns when used against an empty collection. Also in 0.8.3.

* - after discussions with the original project folks working with zope securityMike Bayer2013-08-021-0/+2
| | | | | | | | | | | proxies, they aren't overriding getattr() or setattr() at all. so all the hardcoded getattr()/setattr() is removed from collections.py. Lots of these getattr/setattr were against the attributeimpl and decorated functions and don't seem like they'd ever be needed; for a user that needs special access to a collection, we can evaulate that use case and add a single point of "unwrapping", and probably add a hook for it via InstrumentationManager so that the collection implementation isn't complicated by it.
* rework the test here to suit 0.8/0.9 mostly, include time testsMike Bayer2013-08-021-94/+86

* - add a clear() to SetIsh here so that the control/direct gets clearedMike Bayer2013-08-021-10/+16
| | | | | before we do the pop() test. - make clear()/pop() test unconditional
* Added a new attribute :attr:`.Session.info` to :class:`.Session`;Mike Bayer2013-08-021-0/+17
| | | | | | | | this is a dictionary where applications can store arbitrary data local to a :class:`.Session`. The contents of :attr:`.Session.info` can be also be initialized using the ``info`` argument of :class:`.Session` or :class:`.sessionmaker`.
* - assorted fixes raised by pypy 2.1beta2, but all of which are goodMike Bayer2013-08-013-9/+14
| | | | | | | | | | | | | | | 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 in common table expression system where if the CTE wereMike Bayer2013-07-311-0/+29

* - Removal of event listeners is now implemented. The feature isMike Bayer2013-07-263-35/+248
| | | | | | | | | | | | | | | | provided via the :func:`.event.remove` function. [ticket:2268] - reorganization of event.py module into a package; with the addition of the docstring work as well as the new registry for removal, there's a lot more code now. the package separates concerns and provides a top-level doc for each subsection of functionality - the remove feature works by providing the EventKey object which associates the user-provided arguments to listen() with a global, weak-referencing registry. This registry stores a collection of _ListenerCollection and _DispatchDescriptor objects associated with each set of arguments, as well as the wrapped function which was applied to that collection. The EventKey can then be recreated for a removal, all the _ListenerCollection and _DispatchDescriptor objects are located, and the correct wrapped function is removed from each one.
* - The mechanism by which attribute events pass along anMike Bayer2013-07-262-13/+6
| | | | | | | | | | | | | | | | | | | :class:`.AttributeImpl` as an "initiator" token has been changed; the object is now an event-specific object called :class:`.attributes.Event`. Additionally, the attribute system no longer halts events based on a matching "initiator" token; this logic has been moved to be specific to ORM backref event handlers, which are the typical source of the re-propagation of an attribute event onto subsequent append/set/remove operations. End user code which emulates the behavior of backrefs must now ensure that recursive event propagation schemes are halted, if the scheme does not use the backref handlers. Using this new system, backref handlers can now peform a "two-hop" operation when an object is appended to a collection, associated with a new many-to-one, de-associated with the previous many-to-one, and then removed from a previous collection. Before this change, the last step of removal from the previous collection would not occur. [ticket:2789]
* Fixed bug in ORM-level event registration where the "raw" orMike Bayer2013-07-181-13/+55
| | | | | | "propagate" flags could potentially be mis-configured in some "unmapped base class" configurations. Also in 0.8.3. [ticket:2786]

* A performance fix related to the usage of the :func:`.defer` optionMike Bayer2013-07-133-14/+93
| | | | | | | | | | | | | when loading mapped entities. The function overhead of applying a per-object deferred callable to an instance at load time was significantly higher than that of just loading the data from the row (note that ``defer()`` is meant to reduce DB/network overhead, not necessarily function call count); the function call overhead is now less than that of loading data from the column in all cases. There is also a reduction in the number of "lazy callable" objects created per load from N (total deferred values in the result) to 1 (total number of deferred cols). [ticket:2778]
* The newly added SQLite DATETIME arguments storage_format andMike Bayer2013-07-121-1/+46
| | | | | | | regexp apparently were not fully implemented correctly; while the arguments were accepted, in practice they would have no effect; this has been fixed. Also in 0.8.3. [ticket:2781]
* Fixed bug where the expression system relied upon the ``str()``Mike Bayer2013-07-122-0/+53
| | | | | | | | | | | | form of a some expressions when referring to the ``.c`` collection on a ``select()`` construct, but the ``str()`` form isn't available since the element relies on dialect-specific compilation constructs, notably the ``__getitem__()`` operator as used with a Postgresql ``ARRAY`` element. The fix also adds a new exception class :class:`.UnsupportedCompilationError` which is raised in those cases where a compiler is asked to compile something it doesn't know how to. Also in 0.8.3. [ticket:2780]
* 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]

| | | | | | | | | | | | | | | | with @_legacy_signature, will inspect incoming listener functions to see if they match an older signature, will wrap into a newer sig - add an event listen argument named=True, will send all args as kw args so that event listeners can be written with **kw, any combination of names - add a doc system to events that writes out the various calling styles for a given event, produces deprecation messages automatically. a little concerned that it's a bit verbose but will look at it up on RTD for awhile to get a feel. - change the calling signature for bulk update/delete events - we have the BulkUD object right there, and there's at least six or seven things people might want to see, so just send the whole BulkUD in [ticket:2775]
* - Added new method to the :func:`.insert` constructMike Bayer2013-07-052-2/+134
| | | | | | | | | | :meth:`.Insert.from_select`. Given a list of columns and a selectable, renders ``INSERT INTO (table) (columns) SELECT ..``. While this feature is highlighted as part of 0.9 it is also backported to 0.8.3. [ticket:722] - The :func:`.update`, :func:`.insert`, and :func:`.delete` constructs will now interpret ORM entities as FROM clauses to be operated upon, in the same way that select() already does. Also in 0.8.3.
* Fixed bug whereby attribute history functions would failMike Bayer2013-07-041-43/+128
| | | | | | | when an object we moved from "persistent" to "pending" using the :func:`.make_transient` function, for operations involving collection-based backrefs. [ticket:2773]

| | | | | | | | | | | | | | ConnectionRecord/ConnectionFairy is clear; 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()
