Jack Christensen 38ab93613b Make CopyFrom log message more specific 2021-03-11 19:22:40 -06:00
Patrick Hemmer 41fa6e844c Add logging on CopyFrom 
Logging previously only logged statement results on Exec() and Query(), but not CopyFrom(). This makes change makes it consistent.

Jack Christensen 0a2b67c5c5 CopyFromSlice should remember error 2020-12-02 09:32:01 -06:00
Egon Elbre e23c5bec24 add pgx.CopyFromSlice 
Using CopyFromRows can often be inconvenient to use, because you would
need to convert a typed array to an [][]interface{}. Similarly,
implementing a custom CopyFromSource is too verbose for one-off things.

Add CopyFromSlice that allows to more easily convert a slice to a
CopyFromSource. Example:

    copyCount, err := conn.CopyFrom(
        context.Background(),
        pgx.Identifier{"people"},
        []string{"first_name", "last_name", "age"},
        pgx.CopyFromSlice(len(rows), func(i int) ([]interface{}, error) {
            return []interface{user.FirstName, user.LastName, user.Age}, nil
        }),
    )

Jack Christensen 3b9f79e2f3 Fix race condition in CopyFrom 
In case of an error it was possible for the goroutine that builds the
copy stream to still be running after CopyFrom returned. Since that
goroutine uses the connections ConnInfo data types to encode the copy
data it was possible for those types to be concurrently used in an
unsafe fashion.

CopyFrom will no longer return until that goroutine has completed.

Jack Christensen 76348773bd Make Conn.ConnInfo private 2019-09-10 18:09:21 -05:00
Jack Christensen 3675337e5b Update for rename of pgconn.PreparedStatementDescription 2019-08-24 20:44:56 -05:00
Jack Christensen 31705e586a Use pgconn.PreparedStatementDescription directly 
Instead of having similar pgx.PreparedStatement
 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.
 2019-08-24 13:55:57 -05:00
Jack Christensen 583c8d3b25 Use pgproto3.FieldDescription instead of pgx version 
This allows removing a malloc and memcpy.

Jack Christensen cc3461e65d Use golang.org/x/xerrors 2019-04-20 17:43:44 -05:00
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 5eb19bc66a Add *Conn.CopyFrom 
This replaces *Conn.CopyTo. CopyTo was named incorrectly. In PostgreSQL
COPY FROM is the command that copies from the client to the server. In
addition, CopyTo does not accept a schema qualified table name. This
commit introduces the Identifier type which handles multi-part names and
correctly quotes/sanitizes them. The new CopyFrom method uses this
Identifier type.

Conn.CopyTo is deprecated.
