the tree can now run the full suite of tests out of the box.
- Migrated most @supported to @fails_on, @fails_on_everything_but, or (last
resort) @unsupported. @fails_on revealed a slew of bogus test skippage,
which was corrected.
- Added @fails_on_everything_but. Yes, the first usage *was*
"fails_on_everything_but('postgres')". How did you guess!
- Migrated @supported in dialect/* to the new test-class attribute __only_on__.
- Test classes can also have __unsupported_on__ and __excluded_on__.
as the "schema" argument in a Table, will assume that this is the the
user's desired convention, and will explicitly set the "schema" argument
in foreign-key-related reflected tables, thus making them match only
with Table constructors that also use the explicit "schema" argument
(even though its the default schema).
In other words, SA assumes the user is being consistent in this usage.
sets (i.e. when no TypeEngine/String/Unicode type is even being used;
previously it was detecting DBAPI types and converting regardless).
should fix [ticket:800]
- fixed oracle out_parameters, likely broke in beta6
- fixed oracle _normalize_case for encoded names, gets unicode reflection test to work
- a few extra tests tweaked/unsupported for oracle
2. compiler names changed to be less verbose, unused classes removed.
3. Methods on Dialect which return compilers, schema generators, identifier preparers
have changed to direct class references, typically on the Dialect class itself
or optionally as attributes on an individual Dialect instance if conditional behavior is needed.
This takes away the need for Dialect subclasses to know how to instantiate these
objects, and also reduces method overhead by one call for each one.
4. as a result of 3., some internal signatures have changed for things like compiler() (now statement_compiler()), preparer(), etc., mostly in that the dialect needs to be passed explicitly as the first argument (since they are just class references now). The compiler() method on Engine and Connection is now also named statement_compiler(), but as before does not take the dialect as an argument.
5. changed _process_row function on RowProxy to be a class reference, cuts out 50K method calls from insertspeed.py
- Mark everything in a test suite as failed when setUpAll fails.
- Added test coverage for Unicode table names in metadata.reflect()
- @testing.exclude() filters out tests by server version
- Applied exclude to the test suite, MySQL 4.1 passes again (no XA or SAVEPOINT)
- Removed MySQL charset-setting pool hook- charset=utf8&use_unicode=0 works just as well. (Am I nuts? I'd swear this didn't work before.)
- Finally migrated some old MySQL-tests into the dialect test module
- Corrected 'commit' and 'rollback' logic (and comment) for ancient MySQL versions lacking transactions entirely
- Deprecated the MySQL get_version_info in favor of server_version_info
- Added a big hunk-o-doc for MySQL.
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.)
- 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.
- 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
