- The :meth:`.Query.update` method will now convert string key

2014-10-16T18:36:56+00:00

names in the given dictionary of values into mapped attribute names
against the mapped class being updated.  Previously, string names
were taken in directly and passed to the core update statement without
any means to resolve against the mapped entity.  Support for synonyms
and hybrid attributes as the subject attributes of
:meth:`.Query.update` are also supported.
fixes #3228

- tiny refactors #1-#5

- A new style of warning can be emitted which will "filter" up to

2014-08-31T19:22:00+00:00

N occurrences of a parameterized string.   This allows parameterized
warnings that can refer to their arguments to be delivered a fixed
number of times until allowing Python warning filters to squelch them,
and prevents memory from growing unbounded within Python's
warning registries.
fixes #3178

- factor out determination of current version id out of

2014-08-20T18:24:45+00:00

_collect_update_commands and _collect_delete_commands

- simplify PK logic in update for row switch

2014-08-19T21:43:50+00:00

- optimize collection of cols we insert as none

2014-08-18T21:15:04+00:00

- move out checks for table in mapper._pks_by_table

2014-08-18T21:02:52+00:00

- further reorganize collect_insert_commands to distinguish between

2014-08-18T20:44:07+00:00

setting up given values vs. defaults.  again trying to shoot for
making this of more general use

- organize persistence methods in terms of generators,

2014-08-18T20:32:59+00:00

narrow down argument lists and generator items for each function
down to just what each function needs.   This will help for them
to be of more multipurpose use for bulk operations

- major simplification of _collect_update_commands. in particular,

2014-08-18T17:18:46+00:00

we only call upon the history API fully for primary key columns.
We also now skip the whole step of looking at PK columns and using
any history at all if no net changes are detected on the object.
