* - attributes module and test suite moves underneath 'orm' packageMike Bayer2006-10-221-752/+0
| | | | | | | | | | | | | - fixed table comparison example in metadata.txt - docstrings all over the place - renamed mapper _getattrbycolumn/_setattrbycolumn to get_attr_by_column,set_attr_by_column - removed frommapper parameter from populate_instance(). the two operations can be performed separately - fix to examples/adjacencytree/byroot_tree.py to fire off lazy loaders upon load, to reduce query calling - added get(), get_by(), load() to MapperExtension - re-implemented ExtensionOption (called by extension() function) - redid _ExtensionCarrier to function dynamically based on __getattribute__ - added logging to attributes package, indicating the execution of a lazy callable - going to close [ticket:329]

* - "custom list classes" is now implemented via the "collection_class"Mike Bayer2006-10-031-2/+5
| | | | | keyword argument to relation(). the old way still works but is deprecated [ticket:212]
* - added "mutable" flag to PickleType, set to False to allow old (faster) ↵Mike Bayer2006-09-231-4/+3
| | | | | | | behavior - fix attribute unit test - attributes have explicit flag for "mutable_scalars", propigated by ColumnProperty
* - added "pickleable" module to test suite to have cPickle-compatibleMike Bayer2006-09-231-10/+45
| | | | | | | | | | | | | | | | | | | | | | | | test objects - added copy_function, compare_function arguments to InstrumentedAttribute - added MutableType mixin, copy_value/compare_values methods to TypeEngine, PickleType - ColumnProperty and DeferredProperty propigate the TypeEngine copy/compare methods to the attribute instrumentation - cleanup of UnitOfWork, removed unused methods - UnitOfWork "dirty" list is calculated across the total collection of persistent objects when called, no longer has register_dirty. - attribute system can still report "modified" status fairly quickly, but does extra work for InstrumentedAttributes that have detected a "mutable" type where catching the __set__() event is not enough (i.e. PickleTypes) - attribute tracking modified to be more intelligent about detecting changes, particularly with mutable types. TypeEngine objects now take a greater role in defining how to compare two scalar instances, including the addition of a MutableType mixin which is implemented by PickleType. unit-of-work now tracks the "dirty" list as an expression of all persistent objects where the attribute manager detects changes. The basic issue thats fixed is detecting changes on PickleType objects, but also generalizes type handling and "modified" object checking to be more complete and extensible.
* - fixed unfortunate mutating-dictionary glitch from previous checkinMike Bayer2006-09-231-1/+1
| | | | | | - added "batch=True" flag to mapper; if False, save_obj will fully save one object at a time including calls to before_XXXX and after_XXXX

* fix to reset_class_managed to look at noninherited attributes only; an ↵Mike Bayer2006-09-221-1/+10
| | | | artifact of compilation brought this up
* restored "optimistic" behavior of hasparent. its generally disastrous ↵Mike Bayer2006-09-051-5/+15
| | | | without that flag as its impossible to load all lazy loaders, deal with attributes that "noload", etc. just to check for orphan status.
* cleanup/unit test fixesMike Bayer2006-09-031-23/+35

* - further changes to attributes with regards to "trackparent". the "commit" ↵Mike Bayer2006-09-021-18/+13
| | | | | | | | | | operation now sets a "hasparent" flag for all attributes to all objects. that way lazy loads via callables get included in trackparent, and eager loads do as well because the mapper calls commit() on all objects at load time. this is a less shaky method than the "optimistic" thing in the previous commit, but uses more memory and involves more overhead. - some tweaks/cleanup to unit tests
* futher fix to the "orphan state" idea. to avoid setting tons ofMike Bayer2006-09-011-8/+19
| | | | | | | | | | "hasparent" flags on objects as they are loaded, both from lazy and eager loads, the "orphan" check now uses an "optimistic" flag to determine the result if no "hasparent" flag is found for a particular relationship on an instance. if the instance has an _instance_key and therefore was loaded from the database, it is assumed to not be an orphan unless a "False" hasparent flag has been set. if the instance does not have an _instance_key and is therefore transient/pending, it is assumed to be an orphan unless a "True" hasparent flag has been set.

* fixed attribute manager's ability to traverse the full set of managed ↵Mike Bayer2006-06-261-2/+3

* more intelligent "removal" of list items when a list attribute is replaced, ↵Mike Bayer2006-06-161-10/+28
| | | | doesnt actually "remove" the items from teh replaced list just marks them as "removed" from the parent object for history purposes
* fixed bug where if a many-to-many table mapped as "secondary" had other cols ↵Mike Bayer2006-06-161-4/+6
| | | | in it, delete operations would try to match up on those columns. also fixed bug in new attributes if you set a list based attribute to a blank list, properly fires the 'delete' event for the elements of the previous list

* added 'entity_name' keyword argument to mapper. a mapper is now associated ↵Mike Bayer2006-04-031-0/+5
| | | | | | | | with a class via the class object as well as the optional entity_name parameter, which is a string defaulting to None. any number of primary mappers can be created for a class, qualified by the entity name. instances of those classes will issue all of their load and save operations through their entity_name-qualified mapper, and maintain separate identity from an otherwise equilvalent object.
* attributes overhaul #2 - attribute manager now tracks class-level ↵Mike Bayer2006-04-031-72/+64

| | | | immediately removed as well as explicit from dirty/deleted lists. this also changes uow.rollback_object() to remove from those lists, which is strange that it didnt do that before. anyway the mapper, when selecting and creating instances, asks the uow if this already identity-mapped instance is expired, and if so refreshes it on the fly, saving the need for the re-_get() operation, if some other query happens to touch upon the expired object. unit test added to confirm this.
* util: the __setitem__ method on historyarraylist was meaningless, surprising ↵Mike Bayer2006-03-261-3/+12
| | | | | | | | nobody noticed that. types: added PickleType, its slightly trickier than trivial, so OK now its standard. attributes: the level of pain if an AttributeError occurs inside a CallableProp, in combination with an object that implements __getattr__, is too deep for me to put the users through....so convert AttributeErrors to Assertions... engine: im not a fan of catching universal exceptions and squashing them
