MySQL Connector/Python Release Notes
Two informative text files were added:
INFO_BIN
contains information about the
build environment used to produce the distribution, and
INFO_SRC
provides information about the
product version and the source repository from which the
distribution was produced.
(Bug #29454706)
Django 1.11 is now the minimum supported Django version.
For X DevAPI applications, Connector/Python now supports the ability to send connection attributes (key-value pairs that application programs can pass to the server at connect time). Connector/Python defines a default set of attributes, which can be disabled or enabled. In addition, applications can specify attributes to be passed in addition to the default attributes. The default behavior is to send the default attribute set.
For X DevAPI applications, specify connection attributes as a
connection-attributes
parameter in a
connection string, or setting
connection-attributes
as a dictionary inside
the connection settings parameter under the
connection-attributes
key. Both the
mysqlx.get_session()
and
mysqlx.get_client()
methods can receive this
information.
The connection-attributes
parameter value
must be empty (the same as specifying true
),
a Boolean
value (true
or
false
to enable or disable the default
attribute set), or a list or zero or more
key=value
specifiers separated by commas (to
be sent in addition to the default attribute set). Within a
list, a missing key value evaluates as an empty string. An
example connection string:
mysqlx://user:password@host:33060/schema?connection-attributes=[foo=bar,baz=qux,quux]
Application-defined attribute names cannot begin with
_
because such names are reserved for
internal attributes.
If connection attributes are not specified in a valid way, an error occurs and the connection attempt fails.
For general information about connection attributes, see Performance Schema Connection Attribute Tables.
Connector/Python now has improved support for resetting sessions in connection pools. Returning a session to the pool drops session-related objects such as temporary tables, session variables, and transactions, but the connection remains open and authenticated so that reauthentication is not required when the session is reused.
Protobuf was updated to Protobuf 3.6.1.
For X DevAPI, performance for statements that are executed
repeatedly (two or more times) is improved by using server-side
prepared statements for the second and subsequent executions.
This happens internally; applications need take no action and
API behavior should be the same as previously. For statements
that change, repreparation occurs as needed. Providing different
data values or different offset()
or
limit()
values does not count as a change.
Instead, the new values are passed to a new invocation of the
previously prepared statement.
Added a "username" alias for the "user" connection argument. Thanks to Matthew Woods for the patch. (Bug #29324966, Bug #94248)
Solaris 11 package files had the expected owner/group set as pb2user/common instead of root/bin. (Bug #29278489)
CRUD operations would not allow referencing a renamed column (AS SomeLabel) from the fetched result. (Bug #29001628)
Fixed a memory corruption issue that caused an unexpected halt when fetching fields. (Bug #28479054)
Querying an empty LONG BLOB raised an IndexError exception. (Bug #27897881, Bug #90519)
