- removed patch fix_test_reflection.patch (included upstream)
- update to version 1.2.9:
* orm
+ [orm] [bug] Fixed issue where chaining multiple join elements
inside of Query.join() might not correctly adapt to the previous
left-hand side, when chaining joined inheritance classes that
share the same base class.
References: #3505
+ [orm] [bug] Fixed bug in cache key generation for baked queries
which could cause a too-short cache key to be generated for the
case of eager loads across subclasses. This could in turn cause
the eagerload query to be cached in place of a non-eagerload
query, or vice versa, for a polymorhic “selectin” load, or
possibly for lazy loads or selectin loads as well.
References: #4287
+ [orm] [bug] Fixed bug in new polymorphic selectin loading where
the BakedQuery used internally would be mutated by the given
loader options, which would both inappropriately mutate the
subclass query as well as carry over the effect to subsequent
queries.
References: #4286
+ [orm] [bug] Fixed regression caused by #4256 (itself a
regression fix for #4228) which breaks an undocumented behavior
which converted for a non-sequence of entities passed directly
to the Query constructor into a single-element sequence. While
this behavior was never supported or documented, it’s already in
use so has been added as a behavioral contract to Query.
References: #4269
+ [orm] [bug] Fixed an issue that was both a performance
regression in 1.2 as well as an incorrect result regarding the
“baked” lazy loader, involving the generation of cache keys from
the original Query object’s loader options. If the loader
options were built up in a “branched” style using common base
elements for multiple options, the same options would be
rendered into the cache key repeatedly, causing both a
performance issue as well as generating the wrong cache
key. This is fixed, along with a performance improvement when
such “branched” options are applied via Query.options() to
prevent the same option objects from being applied repeatedly.
References: #4270
* sql
+ [sql] [bug] Fixed regression in 1.2 due to #4147 where a Table
that has had some of its indexed columns redefined with new
ones, as would occur when overriding columns during reflection
or when using Table.extend_existing, such that the
Table.tometadata() method would fail when attempting to copy
those indexes as they still referred to the replaced column. The
copy logic now accommodates for this condition.
References: #4279
* mysql
+ [mysql] [bug] Fixed percent-sign doubling in
mysql-connector-python dialect, which does not require
de-doubling of percent signs. Additionally, the mysql-
connector-python driver is inconsistent in how it passes the
column names in cursor.description, so a workaround decoder has
been added to conditionally decode these
randomly-sometimes-bytes values to unicode only if needed. Also
improved test support for mysql-connector-python, however it
should be noted that this driver still has issues with unicode
that continue to be unresolved as of yet.
+ [mysql] [bug] Fixed bug in index reflection where on MySQL 8.0
an index that includes ASC or DESC in an indexed column
specfication would not be correctly reflected, as MySQL 8.0
introduces support for returning this information in a table
definition string.
References: #4293
+ [mysql] [bug] Fixed bug in MySQLdb dialect and variants such as
PyMySQL where an additional “unicode returns” check upon
connection makes explicit use of the “utf8” character set, which
in MySQL 8.0 emits a warning that utf8mb4 should be used. This
is now replaced with a utf8mb4 equivalent. Documentation is also
updated for the MySQL dialect to specify utf8mb4 in all
examples. Additional changes have been made to the test suite to
use utf8mb3 charsets and databases (there seem to be collation
issues in some edge cases with utf8mb4), and to support
configuration default changes made in MySQL 8.0 such as
explicit_defaults_for_timestamp as well as new errors raised for
invalid MyISAM indexes.
References: #4283
+ [mysql] [bug] The Update construct now accommodates a Join
object as supported by MySQL for UPDATE..FROM. As the construct
already accepted an alias object for a similar purpose, the
feature of UPDATE against a non-table was already implied so
this has been added.
References: #3645
* sqlite
+ [sqlite] [bug] Fixed issue in test suite where SQLite 3.24 added
a new reserved word that conflicted with a usage in
TypeReflectionTest. Pull request courtesy Nils Philippsen.
* mssql
+ [mssql] [bug] Fixed bug in MSSQL reflection where when two
same-named tables in different schemas had same-named primary
key constraints, foreign key constraints referring to one of the
tables would have their columns doubled, causing errors. Pull
request courtesy Sean Dunn.
References: #4228
+ [mssql] [bug] [py3k] Fixed issue within the SQL Server dialect
under Python 3 where when running against a non-standard SQL
server database that does not contain either the
“sys.dm_exec_sessions” or “sys.dm_pdw_nodes_exec_sessions”
views, leading to a failure to fetch the isolation level, the
error raise would fail due to an UnboundLocalError.
References: #4273
* oracle
+ [oracle] [feature] Added a new event currently used only by the
cx_Oracle dialect, DialectEvents.setiputsizes(). The event
passes a dictionary of BindParameter objects to DBAPI-specific
type objects that will be passed, after conversion to parameter
names, to the cx_Oracle cursor.setinputsizes() method. This
allows both visibility into the setinputsizes process as well as
the ability to alter the behavior of what datatypes are passed
to this method.
See als Fine grained control over cx_Oracle data binding and performance with setinputsizes
References: #4290
+ [oracle] [bug] [mysql] Fixed INSERT FROM SELECT with CTEs for
the Oracle and MySQL dialects, where the CTE was being placed
above the entire statement as is typical with other databases,
however Oracle and MariaDB 10.2 wants the CTE underneath the
“INSERT” segment. Note that the Oracle and MySQL dialects don’t
yet work when a CTE is applied to a subquery inside of an UPDATE
or DELETE statement, as the CTE is still applied to the top
rather than inside the subquery.
References: #4275
* misc
+ [feature] [ext] Added new attribute Query.lazy_loaded_from which
is populated with an InstanceState that is using this Query in
order to lazy load a relationship. The rationale for this is
that it serves as a hint for the horizontal sharding feature to
use, such that the identity token of the state can be used as
the default identity token to use for the query within
id_chooser().
References: #4243
+ [bug] [py3k] Replaced the usage of inspect.formatargspec() with
a vendored version copied from the Python standard library, as
inspect.formatargspec() is deprecated and as of Python 3.7.0 is
emitting a warning.
References: #4291
