georgysavva e27a6e71b5 Wrap stdlib Conn.Close() and Stmt.Close() with default 5 seconds timeout. 2020-05-02 16:57:39 +03:00
georgysavva 7738775417 Include context into stdlib.wrapTx{} in order to propagate it to the underlying pgx.Tx.Commit() and Rollback() methods. 2020-04-02 15:30:55 +03:00

Jack Christensen 77c1076d39 stdlib.ReleaseConn closes connections left in invalid state 
If a connection is in a transaction or has an open result set then
close the connection when returning it to database/sql. When next
database/sql attempts to use it the connection will return
driver.ErrBadConn and database/sql will remove it from the pool.

Johan Brandhorst d75362f396 Add back GetDefaultDriver 
This method is useful when it is necessary
to wrap the pgx stdlib driver, for example to
add tracing and metrics.

Jack Christensen a262126b5c Replace IsAlive with IsClosed 
IsAlive is ambiguous because the connection may be dead and we do not
know it. It implies the possibility of a ping. IsClosed is clearer -- it
does not promise the connection is alive only that it hasn't been
closed.

 2019-08-24 14:29:05 -05:00
Jack Christensen 6972a57421 pgtype.OID type should only be used for scanning and encoding values 
It was a mistake to use it in other contexts. This made interop
difficult between pacakges that depended on pgtype such as pgx and
packages that did not like pgconn and pgproto3. In particular this was
awkward for prepared statements.

This is preparation for removing pgx.PreparedStatement in favor of
pgconn.PreparedStatement.

Jack Christensen c3e41872a8 Resplit Begin and BeginEx 
This is in preparation for a Begin / Tx interface that will similate
nested transactions with savepoints.

In addition, this passes the TxOptions struct by value and thereby
removes an allocation.

Jack Christensen 66625e6489 Prepare takes context 
Also remove PrepareEx. It's primary usage was for context. Supplying
parameter OIDs is unnecessary when you can type cast in the query SQL.
If it does become necessary or desirable to add options back it can be
added in a backwards compatible way by adding a varargs as last
argument.

Jack Christensen c53c9e6eb5 Remove simple protocol and one round trip query options 
It is impossible to guarantee that the a query executed with the simple
protocol will behave the same as with the extended protocol. This is
because the normal pgx path relies on knowing the OID of query
parameters. Without this encoding a value can only be determined by the
value instead of the combination of value and PostgreSQL type. For
example, how should a []int32 be encoded? It might be encoded into a
PostgreSQL int4[] or json.

Removal also simplifies the core query path.

The primary reason for the simple protocol is for servers like PgBouncer
that may not be able to support normal prepared statements. After
further research it appears that issuing a "flush" instead "sync" after
preparing the unnamed statement would allow PgBouncer to work.

The one round trip mode can be better handled with prepared statements.

As a last resort, all original server functionality can still be accessed by
dropping down to PgConn.

James Hartig 6d336eccb1 Added LastStmtSent and use it to retry on errors if statement was not sent 
Previously, a failed connection could be put back in a pool and when the
next query was attempted it would fail immediately trying to prepare the
query or reset the deadline. It wasn't clear if the Query or Exec call
could safely be retried since there was no way to know where it failed.

You can now call LastQuerySent and if it returns false then you're
guaranteed that the last call to Query(Ex)/Exec(Ex) didn't get far enough
to attempt to send the query. The call can be retried with a new
connection.

This is used in the stdlib to return a ErrBadConn if a network error
occurred and the statement was not attempted.

stdlib: fix race with Driver.configs in Open 
The Driver.configs map is protected by configMutex in
registerDriverConfig and unregisterDriverConfig, but not in Open. This
results in a race if Open is called while another goroutine is
registering/unregistering a DriverConfig.

Jackson Owens 14f1f2aa01 stdlib: allow nested database/sql/driver.Drivers 
database/sql/driver.Driver implementations can be nested, with each
layer adding additional functionality. If pgx/stdlib.Driver is wrapped
in another driver.Driver implementation, AcquireConn will error,
detecting that the *sql.DB's driver is not (directly) pgx.Driver.

It looks like it should be possible to support the current functionality
without requiring that the top-level Driver be pgx/stdlib.Driver, but
it requires using a global map of fakeTxConns instead of a per-Driver
map of fakeTxConns.

Is this reasonable?
