database/sql: deflake query cancel tests

2016-11-30T18:40:03+00:00

Rather then using a sleep in the fake DB, go to a channel
select and wait for the context to be done.

database/sql: do not bypass the driver locks with Context methods

2016-11-29T18:52:38+00:00

When context methods were initially added it was attempted to unify
behavior between drivers without Context methods and those with
Context methods to always return right away when the Context expired.
However in doing so the driver call could be executed outside of the
scope of the driver connection lock and thus bypassing thread safety.

The new behavior waits until the driver operation is complete. It then
checks to see if the context has expired and if so returns that error.

database/sql: add option to use named parameter in query arguments

2016-10-17T07:56:35+00:00

Modify the new Context methods to take a name-value driver struct.
This will require more modifications to drivers to use, but will
reduce the overall number of structures that need to be maintained
over time.

database/sql: add support for multiple result sets

2016-10-15T07:13:17+00:00

Many database systems allow returning multiple result sets
in a single query. This can be useful when dealing with many
intermediate results on the server and there is a need
to return more then one arity of data to the client.

all: single space after period.

2016-03-02T00:13:47+00:00

The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.

database/sql: avoid deadlock waiting for connections

2015-10-16T15:17:03+00:00

Previously with db.maxOpen > 0, db.maxOpen+n failed connection attempts
started concurrently could result in a deadlock. DB.conn and
DB.openNewConnection did not trigger the DB.connectionOpener go routine
after a failed connection attempt. This omission could leave go routines
waiting for DB.connectionOpener forever.

In addition the logic to track the state of the pool was inconsistent.
db.numOpen was sometimes incremented optimistically and sometimes not.
This change harmonizes the logic and eliminates the db.pendingOpens
variable, making the logic easier to understand and maintain.
