this one has some pretty key fixes in it, and a pretty hefty amount
of refactoring to sessions/unit of work behavior.
important in this release is:
- global_connect() / default MetaData has been restored, in the
manner similar to 0.1's global "ProxyEngine" . I already noticed
some Pylons folks getting tripped up over an example that uses this,
so that should work now.
- oracle URLs fixed - somehow the translation of URL object to
connect() string was totally hosed, so thats fixed, plus you can
connect based on host/port as well as TNS name
- firebird - its there ! not quite finished, but passing the
majority of unit tests under 0.2. not sure if reflection is totally
working yet.
- inheritance - a lot more is possible now. a few people are
storing object relationships that i never imagined could go straight
into relational tables.
a fair amount has changed under the hood in this one with regards to
ORM functionality and some with "threadlocal" connection/transaction
management (again), so please let me know of any new quirks introduced.
changelog:
0.2.2
- big improvements to polymorphic inheritance behavior, enabling it
to work with adjacency list table structures [ticket:190]
- major fixes and refactorings to inheritance relationships overall,
more unit tests
- fixed "echo_pool" flag on create_engine()
- fix to docs, removed incorrect info that close() is unsafe to use
with threadlocal strategy (its totally safe !)
- create_engine() can take URLs as string or unicode [ticket:188]
- firebird support partially completed;
thanks to James Ralston and Brad Clements for their efforts.
- Oracle url translation was broken, fixed, will feed host/port/sid
into cx_oracle makedsn() if 'database' field is present, else uses
straight TNS name from the 'host' field
- fix to using unicode criterion for query.get()/query.load()
- count() function on selectables now uses table primary key or
first column instead of "1" for criterion, also uses label "rowcount"
instead of "count".
- got rudimental "mapping to multiple tables" functionality cleaned up,
more correctly documented
- restored global_connect() function, attaches to a DynamicMetaData
instance called "default_metadata". leaving MetaData arg to Table
out will use the default metadata.
- fixes to session cascade behavior, entity_name propigation
- reorganized unittests into subdirectories
- more fixes to threadlocal connection nesting patterns
