delta/python-packages/sqlalchemy.git/lib/sqlalchemy/orm, branch pr/128

- The "resurrect" ORM event has been removed. This event hook had

2014-08-25T21:00:21+00:00

no purpose since the old "mutable attribute" system was removed
in 0.8.
fixes #3171

- 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.

- Fixed bug where attribute "set" events or columns with

2014-08-18T00:06:16+00:00

``@validates`` would have events triggered within the flush process,
when those columns were the targets of a "fetch and populate"
operation, such as an autoincremented primary key, a Python side
default, or a server-side default "eagerly" fetched via RETURNING.
fixes #3167

- support dialects w/o sane multi row count again
