to TEXT/CLOB when no length is present now occurs *only* for an exact type
of String or Unicode with no arguments. If you use VARCHAR or NCHAR
(subclasses of String/Unicode) with no length, they will be interpreted
by the dialect as VARCHAR/NCHAR; no "magic" conversion happens there.
This is less surprising behavior and in particular this helps Oracle keep
string-based bind parameters as VARCHARs and not CLOBs [ticket:793].
- inline default execution occurs for *all* non-PK columns
unconditionally - preexecute only for non-executemany PK cols on
PG, Oracle, etc.
- new default docs
- all executemany() style calls put all sequences and SQL defaults inline into a single SQL statement
and don't do any pre-execution
- regular Insert and Update objects can have inline=True, forcing all executions to be inlined.
- no last_inserted_ids(), lastrow_has_defaults() available with inline execution
- calculation of pre/post execute pushed into compiler; DefaultExecutionContext greatly simplified
- fixed postgres reflection of primary key columns with no sequence/default generator, sets autoincrement=False
- fixed postgres executemany() behavior regarding sequences present, not present, passivedefaults, etc.
- all tests pass for sqlite, mysql, postgres; oracle tests pass as well as they did previously including all
insert/update/default functionality
- Fixed anonymous pk reflection for mysql 5.1
- Tested table and view reflection against the 'sakila' database from
MySQL AB on 3.23 - 6.0. (with some schema adjustments, obviously)
Maybe this will go into the SA test suite someday.
- Tweaked mysql server version tuplification, now also splitting on hyphens
- Light janitorial
Test currently fails due to two problems in postgres.py, but I'm leaving
it uncorrected for now as its not clear what the original intent was
for lists.
- also omitted all modules and classes that aren't expicitly public
- omitted 'Smallinteger' (small i), but it's still in schema
- omitted NullType-related items from types.__all__
- patched up a few tests to use sql.table and sql.column, other related.
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
- mysql can now generate DISTINCT or ALL for queries, select(..., distinct='ALL')
- documented 'prefixes' arg to select()
- rearranged doc order for select args to mirror that of a generated statement
- went nutty and fixed wrapping and line length on most docstrings in sql.py
- marked as unsupported for mssql all two-phase and nested transcation tests
- marked as unsupported for mssql various transactional/session tests which require two connections looking at uncommitted/external data at the same time (ms-sql cant handle it)
- put better explicit closeout step in unitofwork.py tests to appease ms-sqls hard locking
Added BIT and SET ([ticket:674])- all mysql data types are now covered!
Fix for YEAR DDL generation, also no longer a concatenable type.
Expanded docs for some mysql column esoterica.
- 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.
Added TINYINT [ticket:691]- whoa, how did that one go missing for so long?
Added a charset-fixing pool listener. The driver-level option doesn't help everyone with this one.
New reflector code not quite done and omiited from this commit.
requires the schema to be explicit; i.e. ForeignKey('alt_schema.users.id')
- the fix in "schema" above fixes postgres reflection of foreign keys from an
alt-schema table to a public schema table
- 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.
