delta/python-packages/sqlalchemy.git/lib/sqlalchemy/engine/reflection.py, branch ticket_3230

- use provide_metadata for new unique constraint / index tests

2014-10-04T23:06:35+00:00

- add a test for PG reflection of unique index without any unique
constraint
- for PG, don't include 'duplicates_constraint' in the entry
if the index does not actually mirror a constraint
- use a distinct method for unique constraint reflection within table
- catch unique constraint not implemented condition; this may
be within some dialects and also is expected to be supported by
Alembic tests
- migration + changelogs for #3184
- add individual doc notes as well to MySQL, Postgreql
fixes #3184

Merge branch 'reflect-unique-constraints' of https://bitbucket.org/jerdfelt/sqlalchemy into pr30

2014-10-04T21:47:53+00:00

- cyclomatic complexity; break up reflecttable(), goes from E to B

Reflect unique constraints when reflecting a Table object

2014-09-17T20:19:50+00:00

Calls to reflect a table did not create any UniqueConstraint objects.
The reflection core made no calls to get_unique_constraints and as
a result, the sqlite dialect would never reflect any unique constraints.

MySQL transparently converts unique constraints into unique indexes, but
SQLAlchemy would reflect those as an Index object and as a
UniqueConstraint. The reflection core will now deduplicate the unique
constraints.

PostgreSQL would reflect unique constraints as an Index object and as
a UniqueConstraint object. The reflection core will now deduplicate
the unique indexes.

- Added :meth:`.Inspector.get_temp_table_names` and

2014-09-17T19:15:21+00:00

:meth:`.Inspector.get_temp_view_names`; currently, only the
SQLite dialect supports these methods.    The return of temporary
table and view names has been **removed** from SQLite's version
of :meth:`.Inspector.get_table_names` and
:meth:`.Inspector.get_view_names`; other database backends cannot
support this information (such as MySQL), and the scope of operation
is different in that the tables can be local to a session and
typically aren't supported in remote schemas.
fixes #3204

- An adjustment to table/index reflection such that if an index

2014-09-02T18:18:09+00:00

reports a column that isn't found to be present in the table,
a warning is emitted and the column is skipped.  This can occur
for some special system column situations as has been observed
with Oracle. fixes #3180

PEP8 style fixes

2014-07-14T00:10:55+00:00

- break up the copyright comment as part of a pass

2014-07-09T22:26:55+00:00

to get all flake8 passing

Documentation fix-up: "its" vs. "it's"

2014-05-11T14:49:56+00:00

Removed ungrammatical apostrophes from documentation, replacing
"it's" with "its" where appropriate (but in a few cases with "it is"
when that read better).

While doing that, I also fixed a couple of minor typos etc.
as I noticed them.

- further refine this so that the ordering of columns is maintained as

2014-01-20T23:14:02+00:00

sent to the primary key constraint; existing tests in the PG dialect
confirm this.
