This is especially useful for text formatted arrays and may be useful for future database/sql compatibility. It also makes the code a little simpler as the types no longer have to compute their own size. Along with this, these methods cannot encode NULL. They now return a boolean if they are NULL. This also benefits text array encoding as numeric arrays require NULL to be exactly `NULL` while string arrays require NULL to be `"NULL"`. --- bool.go | 38 +++++------- boolarray.go | 148 +++++++++++++++++++++++--------------------- bytea.go | 44 ++++++------- cid.go | 4 +- cidrarray.go | 4 +- date.go | 36 +++++------ datearray.go | 148 +++++++++++++++++++++++--------------------- float4.go | 36 +++++------ float4array.go | 148 +++++++++++++++++++++++--------------------- float8.go | 36 +++++------ float8array.go | 148 +++++++++++++++++++++++--------------------- inet.go | 46 ++++++-------- inetarray.go | 148 +++++++++++++++++++++++--------------------- int2.go | 36 +++++------ int2array.go | 148 +++++++++++++++++++++++--------------------- int4.go | 36 +++++------ int4array.go | 148 +++++++++++++++++++++++--------------------- int8.go | 36 +++++------ int8array.go | 148 +++++++++++++++++++++++--------------------- name.go | 4 +- oid.go | 4 +- pgtype.go | 29 +++++---- pgtype_test.go | 4 +- pguint32.go | 36 +++++------ qchar.go | 16 +++-- text.go | 22 +++---- text_element.go | 112 --------------------------------- textarray.go | 148 +++++++++++++++++++++----------------------- timestamp.go | 40 ++++++------ timestamparray.go | 148 +++++++++++++++++++++++--------------------- timestamptz.go | 36 +++++------ timestamptzarray.go | 148 +++++++++++++++++++++++--------------------- to-consider.txt | 9 --- typed_array.go.erb | 148 +++++++++++++++++++++++--------------------- typed_array_gen.sh | 22 +++---- varchararray.go | 4 +- xid.go | 4 +- 37 files changed, 1185 insertions(+), 1285 deletions(-) delete mode 100644 text_element.go delete mode 100644 to-consider.txt diff --git a/bool.go b/bool.go index b7bc14d0..9764fafe 100644 --- a/bool.go +++ b/bool.go @@ -5,8 +5,6 @@ import ( "io" "reflect" "strconv" - - "github.com/jackc/pgx/pgio" ) type Bool struct { @@ -100,14 +98,12 @@ func (dst *Bool) DecodeBinary(src []byte) error { return nil } -func (src Bool) EncodeText(w io.Writer) error { - if done, err := encodeNotPresent(w, src.Status); done { - return err - } - - _, err := pgio.WriteInt32(w, 1) - if err != nil { - return nil +func (src Bool) EncodeText(w io.Writer) (bool, error) { + switch src.Status { + case Null: + return true, nil + case Undefined: + return false, errUndefined } var buf []byte @@ -117,18 +113,16 @@ func (src Bool) EncodeText(w io.Writer) error { buf = []byte{'f'} } - _, err = w.Write(buf) - return err + _, err := w.Write(buf) + return false, err } -func (src Bool) EncodeBinary(w io.Writer) error { - if done, err := encodeNotPresent(w, src.Status); done { - return err - } - - _, err := pgio.WriteInt32(w, 1) - if err != nil { - return nil +func (src Bool) EncodeBinary(w io.Writer) (bool, error) { + switch src.Status { + case Null: + return true, nil + case Undefined: + return false, errUndefined } var buf []byte @@ -138,6 +132,6 @@ func (src Bool) EncodeBinary(w io.Writer) error { buf = []byte{0} } - _, err = w.Write(buf) - return err + _, err := w.Write(buf) + return false, err } diff --git a/boolarray.go b/boolarray.go index a9b8bf50..f7323281 100644 --- a/boolarray.go +++ b/boolarray.go @@ -152,26 +152,22 @@ func (dst *BoolArray) DecodeBinary(src []byte) error { return nil } -func (src *BoolArray) EncodeText(w io.Writer) error { - if done, err := encodeNotPresent(w, src.Status); done { - return err +func (src *BoolArray) EncodeText(w io.Writer) (bool, error) { + switch src.Status { + case Null: + return true, nil + case Undefined: + return false, errUndefined } if len(src.Dimensions) == 0 { - _, err := pgio.WriteInt32(w, 2) - if err != nil { - return err - } - - _, err = w.Write([]byte("{}")) - return err + _, err := io.WriteString(w, "{}") + return false, err } - buf := &bytes.Buffer{} - - err := EncodeTextArrayDimensions(buf, src.Dimensions) + err := EncodeTextArrayDimensions(w, src.Dimensions) if err != nil { - return err + return false, err } // dimElemCounts is the multiples of elements that each array lies on.

That would finish removing Nullable interface. - -Also, consider whether arrays and ranges could be represented as generic data types or more common code could be extracted instead of using code generation. diff --git a/typed_array.go.erb b/typed_array.go.erb index 316439ef..2e9b77ea 100644 --- a/typed_array.go.erb +++ b/typed_array.go.erb @@ -151,26 +151,22 @@ func (dst *<%= pgtype_array_type %>) DecodeBinary(src []byte) error { return nil } -func (src *<%= pgtype_array_type %>) EncodeText(w io.Writer) error { - if done, err := encodeNotPresent(w, src.Status); done { - return err +func (src *<%= pgtype_array_type %>) EncodeText(w io.Writer) (bool, error) { + switch src.Status { + case Null: + return true, nil + case Undefined: + return false, errUndefined } if len(src.Dimensions) == 0 { - _, err := pgio.WriteInt32(w, 2) - if err != nil { - return err - } - - _, err = w.Write([]byte("{}")) - return err + _, err := io.WriteString(w, "{}") + return false, err } - buf := &bytes.Buffer{} - - err := EncodeTextArrayDimensions(buf, src.Dimensions) + err := EncodeTextArrayDimensions(w, src.Dimensions) if err != nil { - return err + return false, err } // dimElemCounts is the multiples of elements that each array lies on.

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. --- cid_test.go | 3 --- testutil/testutil.go | 30 ------------------------------ xid_test.go | 3 --- 3 files changed, 36 deletions(-) diff --git a/cid_test.go b/cid_test.go index 0dfc56d4..924e4cf3 100644 --- a/cid_test.go +++ b/cid_test.go @@ -20,9 +20,6 @@ func TestCIDTranscode(t *testing.T) { testutil.TestPgxSuccessfulTranscodeEqFunc(t, pgTypeName, values, eqFunc) -

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. Because pgx depends on pgtype and the tests for pgtype depend on pgx this change will require a couple back and forth commits to get the go.mod dependecies correct. --- go.mod | 7 ++++--- go.sum | 31

EncodeText, and MarshalJSON on T instead of *T Methods defined on T are also available on *T. This change makes Value consistent with database/sql Value implementations. It also makes Value, EncodeBinary, and EncodeText more convenient to use because you can pass T or *T as an argument to a query. The MarshalJSON change is even more significant because without it json.Marshal would generate the "%v" format instead of the implemented MarshalJSON. Thought this technically changes the interface, because *T will be automatically dereferenced as needed it shouldn't be a breaking change.

When passed to Scan, Row() should have first argument of type *bool to flag NULL values returned from query. --- composite.go | 128 ++++++++++++++++++++++++++++++++++++++++++++++ composite_test.go | 16 ++++-- convert.go | 28 ---------- pgtype.go | 9 ++++ 4 files changed, 150 insertions(+), 31 deletions(-) create mode 100644 composite.go diff --git a/composite.go b/composite.go new file mode 100644 index 00000000..1caa24d6 --- /dev/null +++ b/composite.go @@ -0,0 +1,128 @@ +package pgtype + +import ( + errors "golang.org/x/xerrors" +) + +type composite struct { + fields []Value + status Status +} + +// helper struct to act both as a scanning target and query argument +type rowValue struct { + args []interface{} +} + +// Row helper function builds a value which can be both used to +// "assemble" composite quiery arguments and to scan results back. +// +// When passed as an argument to query, values from Row args will +// be assigned to corresponding fields in a composite type and a single +// composite type will be passed to the PostgreSQL.

used every time. While this was great for performance, on further consideration I think it is too much of a potential foot-gun. This moves back in the other direction. A plan tolerates a change in destination. It even detects a change in destination type and falls back to a new plan. Perfectly matched hot scan paths (e.g. PG int4 to Go int32) are still much faster than they were before this set of optimizations. The first scan of a destination that uses a decoder is faster due to not allocating. It's a little bit slower on subsequent runs than before this set of optimizations. But it is preferable to optimize for the most common scan targets (e.g. *int32, *int64, *string) over generic decoder destinations.

Get implicitly allowed returning a reference to an internal value (e.g. a []byte) but AssignTo was documented as requiring a deep copy. This inconsistency meant that either Get was unsafe or the deep copy in AssignTo was superfluous. In addition, Scan into a []byte skips going through Bytea and returns a []byte of the unparsed bytes directly. i.e. a reference not a copy.

Adds array support - previously only slices were supported. Adds new test cases for multidimensional arrays and slices. All previous test cases are unmodified and passed (fully backwards compatible). Removes hard-coded type conversions for arrays, instead now relies on the type support of the array element's type conversion support. Less maintenance for arrays, new type conversions are automatically supported when array's element gains new type support. Simplifies typed_array_gen.sh generator script by removing the hard-coded single-dimensional types for arrays. Only typed_array.go.erb and typed_array_gen.sh have been changed + 1 new auxiliary function in array.go file + additional tests in test files for each array. Other changes are from generated code. --- aclitem_array.go | 212 ++++++++----- aclitem_array_test.go | 171 +++++++++++ array.go | 22 ++ bool_array.go | 212 ++++++++----- bool_array_test.go | 125

af0ca3a39b16dc19b75f40fd5fe38a79c9b0b5a8 Mon Sep 17 00:00:00 2001 From: Jack Christensen Date: Sat, 31 Oct 2020 17:12:16 -0500 Subject: [PATCH 302/373] Fix simple protocol empty array and original recursive empty array issue Original issue https://github.com/jackc/pgtype/issues/68 This crash occurred in the recursive assignment system used to support multidimensional arrays. This was fixed in 9639a69d451f55456f598c1aa8b93053f8df3088. However, that fix incorrectly used nil instead of an empty slice. In hindsight, it appears the fundamental error is that an assignment to a slice of a type that is not specified is handled with the recursive / reflection path. Or another way of looking at it is as an unexpected feature where []T can now be scanned if individual elements are assignable to T even if []T is not specifically handled. But this new reflection / recursive path did not handle empty arrays. This fix handles the reflection path for an empty slice by allocating an empty slice. --- aclitem_array.go | 11 +++++++---- aclitem_array_test.go | 2 +- bool_array.go | 11 +++++++---- bool_array_test.go | 2 +- bpchar_array.go | 11 +++++++---- bytea_array.go | 11 +++++++---- bytea_array_test.go | 2 +- cidr_array.go | 11 +++++++---- cidr_array_test.go | 4 ++-- date_array.go | 11 +++++++---- date_array_test.go | 2 +- enum_array.go | 11 +++++++---- enum_array_test.go | 2 +- float4_array.go | 11 +++++++---- float4_array_test.go | 2 +- float8_array.go | 11 +++++++---- float8_array_test.go | 2 +- hstore_array.go | 11 +++++++---- hstore_array_test.go | 2 +- inet_array.go | 11 +++++++---- inet_array_test.go | 4 ++-- int2_array.go | 11 +++++++---- int2_array_test.go | 2 +- int4_array.go | 11 +++++++---- int4_array_test.go | 2 +- int8_array.go | 11 +++++++---- int8_array_test.go | 2 +- jsonb_array.go | 11 +++++++---- macaddr_array.go | 11 +++++++---- macaddr_array_test.go | 2 +- numeric_array.go | 11 +++++++---- numeric_array_test.go | 2 +- text_array.go | 11 +++++++---- text_array_test.go | 2 +- timestamp_array.go | 11 +++++++---- timestamp_array_test.go | 2 +- timestamptz_array.go | 11 +++++++---- timestamptz_array_test.go | 2 +- tstzrange_array.go | 11 +++++++---- typed_array.go.erb | 11 +++++++---- uuid_array.go | 11 +++++++---- uuid_array_test.go | 4 ++-- varchar_array.go | 11 +++++++---- varchar_array_test.go | 2 +- 44 files changed, 191 insertions(+), 119 deletions(-) diff --git a/aclitem_array.go b/aclitem_array.go index 229136ec..f4b14433 100644 --- a/aclitem_array.go +++ b/aclitem_array.go @@ -190,10 +190,6 @@ func (dst ACLItemArray) Get() interface{} { func (src *ACLItemArray) AssignTo(dst interface{}) error { switch src.Status { case Present: -

It has Scanner and Valuer implementations already, but adding it to this package allows it to be used with the binary encoding as well. The implementation is very straightforward, but the tests have been made slightly more complicated. The previous version wasn't testing the decimal.Decimal cases, and this change adds those as well as new NullDecimal cases.
