Jack Christensen a93025479d Add AfterClose and Conn to Rows 2016-02-13 13:03:06 -06:00
Jack Christensen e8dcf5b3ac Add *Tx.AfterClose hook 
ConnPool now implements its connection with Tx via this hook instead of
manipulating the internals of Tx.

Jack Christensen 93aa2b2e80 ConnPool.Begin retry logic checks connection IsAlive 
ErrDeadConn is returned when calling an already dead connection. But the initial failure returns the real error. So we check for IsAlive instead of ErrDeadConn.

Added test for ConnPool.Begin retry logic.

Remove SelectValue
 2014-07-05 18:23:19 -05:00
Jack Christensen 5b345e80e1 Remove SelectValueTo 
Benchmarks revealed that it is no longer performant enough to pull
its own wait. Using go_db_bench to copy JSON results to HTTP responses
it was ~20% *slower* for ~4BK responses and less than 10% faster for
+1MB responses.

The the performance problem was in io.CopyN / io.Copy. io.Copy
allocates a 32KB buffer if it doesn't have io.WriterTo or io.ReaderFrom
available. This extra alloc on every request was more expensive than
just reading the result into a string and writing it out to the response
body.

Tests indicated that if MsgReader implemented a custom Copy that used a
shared buffer it might have a few percent performance advantage. But the
additional complexity is not worth the performance gain.
