Releasing 0.2.0 last night was so much fun, i just had to do it
again. Some threaded environments revealed a big blunder in the
connection pool where I forgot to restore a plain dictionary to its
proper WeakValueDictionary, which is necessary to allow connections
to be automatically returned to the pool when they fall out of
scope. other than that the TLEngine implementation, which adds
thread-local transaction and connection scope via the
"strategy='threadlocal'" keyword argument, was working very poorly
regarding keeping track of transaction state; i have reworked it and
added six new unittests for it.
0.2.1
- "pool" argument to create_engine() properly propigates
- fixes to URL, raises exception if not parsed, does not pass blank
fields along to the DB connect string (a string such as
user:host@/db was breaking on postgres)
- small fixes to Mapper when it inserts and tries to get
new primary key values back
- rewrote half of TLEngine, the ComposedSQLEngine used with
'strategy="threadlocal"'. it now properly implements engine.begin()/
engine.commit(), which nest fully with connection.begin()/trans.commit
().
added about six unittests.
- major "duh" in pool.Pool, forgot to put back the WeakValueDictionary.
unittest which was supposed to check for this was also silently missing
it. fixed unittest to insure that ConnectionFairy properly falls out
of scope.
- placeholder dispose() method added to SingletonThreadPool, doesnt
do anything yet
- rollback() is automatically called when an exception is raised,
but only if theres no transaction in process (i.e. works more like
autocommit).
- fixed exception raise in sqlite if no sqlite module present
- added extra example detail for association object doc
- Connection adds checks for already being closed
