consists mainly of adjusting fixtures to ensure connections are closed
explicitly. psycopg2cffi also handles unicode bind parameter
names differently than psycopg2, and seems to possibly have a little less
control over floating point values at least in one test which is
marked as a "fail", though will see if it runs differently on linux
than osx..
- changelog for psycopg2cffi, fixes#3052
While "oid" is generally a private type within PG that is not exposed
in modern versions, there are some PG use cases such as large object
support where these types might be exposed, as well as within some
user-reported schema reflection use cases.
fixes#3002
the indexing. this is for more natural operation.
- also add cast() to the JSON expression to complement astext. This integrates
the CAST call which will be needed frequently. Part of [ticket:2687].
- it's a little unclear how more advanced unicode attribute-access is going to go,
some quick attempts at testing yielded strange error messages from psycopg2.
- do other cross linking as mentioned in [ticket:2687].
- build a new Sphinx extension that allows dialect info
to be entered as directives which is then rendered consistently
throughout all dialect/dbapi sections
- break out the "empty_strings" requirement for oracle test
- begin consolidating docs for dialects to be more self contained
- add a separate section for "external" dialects
- not sure how we're going to go with this yet.
the `getitem` operator, i.e. the bracket
operator in Python. This is used at first
to provide index and slice behavior to the
Postgresql ARRAY type, and also provides a hook
for end-user definition of custom __getitem__
schemes which can be applied at the type
level as well as within ORM-level custom
operator schemes.
Note that this change has the effect that
descriptor-based __getitem__ schemes used by
the ORM in conjunction with synonym() or other
"descriptor-wrapped" schemes will need
to start using a custom comparator in order
to maintain this behavior.
- [feature] postgresql.ARRAY now supports
indexing and slicing. The Python [] operator
is available on all SQL expressions that are
of type ARRAY; integer or simple slices can be
passed. The slices can also be used on the
assignment side in the SET clause of an UPDATE
statement by passing them into Update.values();
see the docs for examples.
- [feature] Added new "array literal" construct
postgresql.array(). Basically a "tuple" that
renders as ARRAY[1,2,3].
to pg.ENUM. When False, no CREATE/DROP or
checking for the type will be performed as part
of a table create/drop event; only the
create()/drop)() methods called directly
will do this. Helps with Alembic "offline"
scripts.
[ticket:2029] (also in 0.6.7)
- add "currentmodule" directive to all the dialect type docs to
ensure users import from the dialect package, not the "base" module
"isolation_level" argument, sets transaction isolation
level for that connection only until returned to the
connection pool, for thsoe backends which support it
(SQLite, Postgresql) [ticket:2001]
- disallow the option on Engine (use isolation_level to create_engine()),
Executable (we don't want to check/set per statement)
