table_names changed to accept an explicit connection
ThreadLocalMetaData constructor now takes no arguments. If case_sensitive is needed in a multi-bind context, move it to Table or subclass TLMD to force it.
Banished **kwargs from MetaData
Lots of class doc and docstring improvements around MetaData and TLMD.
Some engine->bind internal naming updates + reorg in schema.
MySQL table_names now return Unicode. (Also, a unicode reflect() unit test is needed.)
feature to fail during a race condition; threads would
raise TimeoutError immediately with no delay if many threads
push the pool into overflow at the same time. this issue has been
fixed.
"engine_or_url", "bind_to", etc. are all present, but deprecated.
they all get replaced by the single term "bind". you also
set the "bind" of MetaData using
metadata.bind = <engine or connection>. this is part of 0.4
forwards compatibility where "bind" is the only keyword.
[ticket:631]
condition that can bypass max_overflow; merged from 0.4 branch r2736-2738.
also made the locking logic simpler, tried to get the test to create a
failure on OSX (not successful)
- added support for reflection of domains [ticket:570]
- types which are missing during reflection resolve to Null type
instead of raising an error
- moved reflection/types/query unit tests specific to postgres to new
postgres unittest module
of MySQL (#583)
- MySQL columns (such as times) with colons in their default values couldn't
be roundtripped, fixed (also in Postgres, but not fixed here.)
- BINARY/VARBINARY columns aren't really binary at all on ancient versions
of MySQL. The type.Binary(123) passthrough now always makes BLOBs.
Removed the short-lived MSBaseBinary.
- Added mysql.get_version_info, given a connectable returns a tuple of server
version info.
- Backed off on the reflection tests for older versions of MySQL, for now.
entry points. loading the built-in database dialects works the
same as always, but if none found will fall back to trying
pkg_resources to load an external module [ticket:521]
this method is called when the invalidate() occurs for a disconnect condition,
so that the entire pool is recreated, thereby avoiding repeat errors on
remaining connections in the pool.
dispose() called as well (also fixed up) but cant guarantee all connections closed.
- removed silly behavior where sqlite would reflect UNIQUE indexes
as part of the primary key (?!)
- added __contains__ support to ColumnCollection; contains_column() method should be removed
- much more functionality moved into ExecutionContext, which impacted
the API used by dialects to some degree
- ResultProxy and subclasses now designed sanely
- merged patch for #522, Unicode subclasses String directly,
MSNVarchar implements for MS-SQL, removed MSUnicode.
- String moves its "VARCHAR"/"TEXT" switchy thing into
"get_search_list()" function, which VARCHAR and CHAR can override
to not return TEXT in any case (didnt do the latter yet)
- implements server side cursors for postgres, unit tests, #514
- includes overhaul of dbapi import strategy #480, all dbapi
importing happens in dialect method "dbapi()", is only called
inside of create_engine() for default and threadlocal strategies.
Dialect subclasses have a datamember "dbapi" referencing the loaded
module which may be None.
- added "mock" engine strategy, doesnt require DBAPI module and
gives you a "Connecition" which just sends all executes to a callable.
can be used to create string output of create_all()/drop_all().
Fix to null FLOAT fields in mssql-trusted.patch
MSSQL: LIMIT with OFFSET now raises an error
MSSQL: can now specify Windows authorization
MSSQL: ignores seconds on DATE columns (DATE fix, part 1)
SchemaItem so that the traversal of items is controlled by the
ClauseVisitor itself, using the method visitor.traverse(item).
accept_visitor() methods can still be called directly but will
not do any traversal of child items. ClauseElement/SchemaItem now
have a configurable get_children() method to return the collection
of child elements for each parent object. This allows the full
traversal of items to be clear and unambiguous (as well as loggable),
with an easy method of limiting a traversal (just pass flags which
are picked up by appropriate get_children() methods). [ticket:501]
- accept_schema_visitor() methods removed, replaced with
get_children(schema_visitor=True)
- various docstring/changelog cleanup/reformatting
