orm

[orm] [bug] Fixed bug where the ORM annotations could be incorrect for the \ 
primaryjoin/secondaryjoin a relationship if one used the pattern \ 
ForeignKey(SomeClass.id) in the declarative mappings. This pattern would leak \ 
undesired annotations into the join conditions which can break aliasing \ 
operations done within Query that are not supposed to impact elements in that \ 
join condition. These annotations are now removed up front if present.

[orm] [bug] In continuing with a similar theme as that of very recent 4349, \ 
repaired issue with RelationshipProperty.Comparator.any() and \ 
RelationshipProperty.Comparator.has() where the “secondary” selectable needs \ 
to be explicitly part of the FROM clause in the EXISTS subquery to suit the case \ 
where this “secondary” is a Join object.

[orm] [bug] Fixed regression caused by 4349 where adding the “secondary” \ 
table to the FROM clause for a dynamic loader would affect the ability of the \ 
Query to make a subsequent join to another entity. The fix adds the primary \ 
entity as the first element of the FROM list since Query.join() wants to jump \ 
from that. Version 1.3 will have a more comprehensive solution to this problem \ 
as well.

[orm] [bug] Fixed bug where chaining of mapper options using \ 
RelationshipProperty.of_type() in conjunction with a chained option that refers \ 
to an attribute name by string only would fail to locate the attribute.

orm declarative

[bug] [declarative] [orm] A warning is emitted in the case that a column() \ 
object is applied to a declarative class, as it seems likely this intended to be \ 
a Column object.

misc

Added support for the write_timeout flag accepted by mysqlclient and pymysql to \ 
be passed in the URL string.

Fixed issue where reflection of a PostgreSQL domain that is expressed as an \ 
array would fail to be recognized.
