- update to version 1.2.8:
* orm
+ [orm] [bug] Fixed regression in 1.2.7 caused by #4228, which
itself was fixing a 1.2-level regression, where the query_cls
callable passed to a Session was assumed to be a subclass of
Query with class method availability, as opposed to an
arbitrary callable. In particular, the dogpile caching example
illustrates query_cls as a function and not a Query subclass.
References: #4256
+ [orm] [bug] Fixed a long-standing regression that occurred in
version 1.0, which prevented the use of a custom MapperOption
that alters the _params of a Query object for a lazy load,
since the lazy loader itself would overwrite those parameters.
This applies to the “temporal range” example on the wiki. Note
however that the Query.populate_existing() method is now
required in order to rewrite the mapper options associated with
an object already loaded in the identity map.
As part of this change, a custom defined MapperOption will now
cause lazy loaders related to the target object to use a non-
baked query by default unless the
MapperOption._generate_cache_key() method is implemented. In
particular, this repairs one regression which occured when
using the dogpile.cache “advanced” example, which was not
returning cached results and instead emitting SQL due to an
incompatibility with the baked query loader; with the change,
the RelationshipCache option included for many releases in the
dogpile example will disable the “baked” query altogether. Note
that the dogpile example is also modernized to avoid both of
these issues as part of issue #4258. References: #4128

- update to version 1.2.6:
* orm
+ [orm] [bug] Fixed bug where using Mutable.associate_with() or
Mutable.as_mutable() in conjunction with a class that has non-
primary mappers set up with alternatively-named attributes would
produce an attribute error. Since non-primary mappers are not
used for persistence, the mutable extension now excludes
non-primary mappers from its instrumentation steps. References:
#4215
* engine
+ [engine] [bug] Fixed bug in connection pool where a connection
could be present in the pool without all of its “connect” event
handlers called, if a previous “connect” handler threw an
exception; note that the dialects themselves have connect
handlers that emit SQL, such as those which set transaction
isolation, which can fail if the database is in a non-available
state, but still allows a connection. The connection is now
invalidated first if any of the connect handlers fail.

* sql
+ [sql] [bug] Fixed a regression that occurred from the previous
fix to #4204 in version 1.2.5, where a CTE that refers to itself
after the CTE.alias() method has been called would not refer to
iself correctly. References: #4204
* postgresql
+ [postgresql] [feature] Added support for “PARTITION BY” in
Postgresql table definitions, using
“postgresql_partition_by”. Pull request courtesy Vsevolod
Solovyov.
* mssql
+ [mssql] [bug] Adjusted the SQL Server version detection for
pyodbc to only allow for numeric tokens, filtering out
non-integers, since the dialect does tuple- numeric comparisons
with this value. This is normally true for all known SQL Server
/ pyodbc drivers in any case. References: #4227
* oracle
+ [oracle] [bug] The minimum cx_Oracle version supported is 5.2
(June 2015). Previously, the dialect asserted against version
5.0 but as of 1.2.2 we are using some symbols that did not
appear until 5.2. References: #4211
* misc
+ [bug] [declarative] Removed a warning that would be emitted when
calling upon __table_args__, __mapper_args__ as named with a
@declared_attr method, when called from a non-mapped declarative
mixin. Calling these directly is documented as the approach to
use when one is overidding one of these methods on a mapped
class. The warning still emits for regular attribute names.

* orm
+ [bug] Fixed Session accounting bug whereby replacing
a deleted object in the identity map with another
object of the same primary key would raise a
"conflicting state" error on rollback(),
if the replaced primary key were established either
via non-unitofwork-established INSERT statement
or by primary key switch of another instance.
[ticket:2583]
* oracle
+ [bug] changed the list of cx_oracle types that are
excluded from the setinputsizes() step to only include
STRING and UNICODE; CLOB and NCLOB are removed. This
is to work around cx_oracle behavior which is broken
for the executemany() call. In 0.8, this same change
is applied however it is also configurable via the
exclude_setinputsizes argument. [ticket:2561]
* mysql
+ [feature] Added "raise_on_warnings" flag to OurSQL
dialect. [ticket:2523]
+ [feature] Added "read_timeout" flag to MySQLdb
dialect. [ticket:2554]

* orm
- [bug] Fixed issue in unit of work whereby setting a non-None
self-referential many-to-one relationship to None would fail
to persist the change if the former value was not already loaded.
[ticket:2477].
- [feature] Added prefix_with() method to Query, calls upon
select().prefix_with() to allow placement of MySQL SELECT
directives in statements. Courtesy Diana Clarke [ticket:2443]
- [bug] Fixed bug in 0.7.6 introduced by [ticket:2409] whereby
column_mapped_collection used against columns that were mapped as
joins or other indirect selectables would fail to function.
- [feature] Added new flag to @validates include_removes. When True,
collection remove and attribute del events will also be sent to
the validation function, which accepts an additional argument
"is_remove" when this flag is used.
- [bug] Fixed bug whereby polymorphic_on column that's not otherwise
mapped on the class would be incorrectly included in a merge()
operation, raising an error. [ticket:2449]
- [bug] Fixed bug in expression annotation mechanics which could
lead to incorrect rendering of SELECT statements with aliases
and joins, particularly when using column_property(). [ticket:2453]
- [bug] Fixed bug which would prevent OrderingList from being
pickleable [ticket:2454]. Courtesy Jeff Dairiki
- [bug] Fixed bug in relationship comparisons whereby calling
unimplemented methods like SomeClass.somerelationship.like()
would produce a recursion overflow, instead of NotImplementedError.
* sql
- [bug] Removed warning when Index is created with no columns;
while this might not be what the user intended, it is a valid use case
