- Importing testenv has no side effects- explicit functions provide similar behavior to the old immediate behavior of testbase
- testing.db has the configured db
- Fixed up the perf/* scripts
for contextual connection, unique_connection() for non-contextual.
- Pool use_threadlocal defaults to True, can be set to false at create_engine()
level with pool_threadlocal=False
- made all logger statements in pool conditional based on a flag calcualted once.
- chagned WeakValueDictionary() used for "threadlocal" pool to be a regular dict
referencing weakref objects. WVD had a lot of overhead, apparently. *CAUTION* -
im pretty confident about this change, as the threadlocal dict gets explicitly managed
anyway, tests pass with PG etc., but keep a close eye on this one regardless.
- changed testing connection closer to work on _ConnectionFairy instances, resulting in
pool checkins, not actual closes
- disabled session two phase test for now, needs work
- added some two-phase support to TLEngine, not tested
- TLTransaction is now a wrapper
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.
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)
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.
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)
"echo" keyword parameters are still functional but set/unset
log levels for their respective classes/instances. all logging
can be controlled directly through the Python API by setting
INFO and DEBUG levels for loggers in the "sqlalchemy" namespace.
class-level logging is under "sqlalchemy.<module>.<classname>",
instance-level logging under "sqlalchemy.<module>.<classname>.<hexid>".
Test suite includes "--log-info" and "--log-debug" arguments
which work independently of --verbose/--quiet. Logging added
to orm to allow tracking of mapper configurations, row iteration
fixes [ticket:229] [ticket:79]
instruct the underlying connection record to reconnect the next
time its called. "invalidate" will also automatically be called
if any error is thrown in the underlying call to connection.cursor().
this will hopefully allow the connection pool to reconnect to a
database that had been stopped and started without restarting
the connecting application [ticket:121]
arguments specified in query string, 'connect_args' argument
to 'create_engine', or custom creation function via 'creator'
function to 'create_engine'.
- added "recycle" argument to Pool, is "pool_recycle" on create_engine,
defaults to 3600 seconds; connections after this age will be closed and
replaced with a new one, to handle db's that automatically close
stale connections [ticket:274]
