* Ensure CTE internals are handled during cloneMike Bayer2016-06-101-0/+17
| | | | | | | | | The CTE construct was missing a _copy_internals() method which would handle CTE-specific structures including _cte_alias, _restates during a clone operation. Change-Id: I9aeac9cd24d8f7ae6b70e52650d61f7c96cb6d7e Fixes: #3722
* Support `postgresql_concurrently` on index dropping.Iuri de Silvio2016-06-081-0/+26
| | | | | | | | | | | | Also adds version detection so that DROP INDEX CONCURRENTLY only renders if the Postgresql version is 9.2 or higher; for CREATE INDEX CONCURRENTLY, version detection is added to allow the phrase to omit if the Postgresql version is less than 8.2.

* | Use the "committed" values when extracting many-to-one lazyload valueMike Bayer2016-06-081-15/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The scalar object set() method calls upon the lazy loader to get at the "old" value of the attriute, however doesn't ensure that the "committed" value of the foreign key attributes is used. If the user has manipulated these attributes and they themselves have pending, non committed changes, we get the "new" value which these attributes would have set up if they were flushed. "old" vs "new" value is always about how the value has changed since the load, so we always have to use the DB-persisted values for everything when looking for "old".

* Add "render_nulls" flag to bulk_insert as optional performance optimizationtsauerwein2016-06-061-2/+25
| | | | | | | | | | | | | | Currently, ``Session.bulk_insert_mappings`` omits NULL values which causes it to break up batches of inserts based on which batches contain NULL and which do not. By adding this flag, the same columns are rendered in the INSERT for all rows allowing them to be batched. The downside is that server-side defaults are omitted.

| * Skip UniqueConstraint marked by unique=True in tometadataMike Bayer2016-06-021-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | Fixes an issue where a Column would be copied with unique=True and at the same time the UniqueConstraint would also be copied, leading to duplicate UniqueConstraints in the target table, when tometadata() is used. Imitates the same logic used by index=True/Index to avoid duplicates. For some reason a fix was implemented for Index long ago but never for UniqueConstraint.

* | Support "blank" schema when MetaData.schema is setMike Bayer2016-05-183-1/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, it was impossible to have a Table that has None for a schema name when the "schema" parameter on MetaData was set. A new symbol sqlalchemy.schema.BLANK_SCHEMA is added which indicates that the schema name should unconditionally be set to None. In particular, this value must be passed within cross-schema foreign key reflection, so that a Table which is in the "default" schema can be represented properly.
