delta/python-packages/sqlalchemy.git/lib/sqlalchemy/dialects/postgresql/psycopg2.py, branch pr/55

- happy new year

2014-01-05T21:57:05+00:00

- make the json serializer and deserializer per-dialect, so that we are

2013-12-17T22:46:09+00:00

compatible with psycopg2's per-connection/cursor approach.  add round trip tests for
both native and non-native.

- rework JSON expressions to be based off getitem exclusively

2013-12-17T20:13:39+00:00

- add support for "standalone" JSON objects; this involves getting CAST
to upgrade the given type of a bound parameter.  should add a core-only test
for this.
- add tests for "standalone" json round trips both with and without unicode
- add mechanism by which we remove psycopg2's "json" handler in order to get
the effect of using our non-native result handlers

Merge branch 'issue_2581' of github.com:nathan-rice/sqlalchemy into pg_json

2013-12-17T19:03:20+00:00

- add "force_nocheck" as a way to turn on unicode=force without even

2013-12-16T02:23:01+00:00

doing the isinstance() check - currently used only by psycopg2 + native enum + py2k.
- didn't realize psycopg2 had UNICODEARRAY extension all this time; replace _PGArray
with just using UNICODEARRAY instead.
- replace unnecessary/inconsistent __import__ in _isolation_lookup.

sqlalchemy/dialects/postgresql/psycopg2:

2013-12-10T15:09:15+00:00

 - Removed unneeded import of psycopg2.extensions

sqlalchemy/dialects/postgresql/pgjson:

2013-12-10T15:01:51+00:00

 - Fixed reference to HSTORE
 - Corrected spelling of SQLAlchemy

 sqlalchemy/dialects/postgresql/psycopg2:
 - Added psycopg2 specific wrapper type for JSON which uses inherent json deserialization facilities
 - Added code to detect and utilize the JSON wrapper if psycopg2 >= 2.5

test/dialect/postgresql/test_types:
- removed reference to use_native_hstore

- evaulate decimal_return_scale statelessly. Don't re-assign to self.decimal_return_scale

2013-11-23T22:19:43+00:00

so that __repr__() is maintained (for alembic tests)

- The precision used when coercing a returned floating point value to

2013-11-23T01:04:19+00:00

Python ``Decimal`` via string is now configurable.  The
flag ``decimal_return_scale`` is now supported by all :class:`.Numeric`
and :class:`.Float` types, which will ensure this many digits are taken
from the native floating point value when it is converted to string.
If not present, the type will make use of the value of ``.scale``, if
the type supports this setting and it is non-None.  Otherwise the original
default length of 10 is used. [ticket:2867]

fix up the isolation level docs which were a mess
