||||
|
||||
* Fix encoding of pointer type in empty interface ( #262 ) |
||||
|
||||
# v0.7.2 - 2021/06/26 |
||||
|
||||
### Fix decoder |
||||
|
||||
* Add decoder for func type to fix decoding of nil function value ( #257 ) |
||||
* Fix stream decoding of []byte type ( #258 ) |
||||
|
||||
### Performance |
||||
|
||||
* Improve decoding performance of map[string]interface{} type ( use `mapassign_faststr` ) ( #256 ) |
||||
* Improve encoding performance of empty interface type ( remove recursive calling of `vm.Run` ) ( #259 ) |
||||
|
||||
### Benchmark |
||||
|
||||
* Add bytedance/sonic as benchmark target ( #254 ) |
||||
|
||||
# v0.7.1 - 2021/06/18 |
||||
|
||||
### Fix decoder |
||||
|
||||
* Fix error when unmarshal empty array ( #253 ) |
||||
|
||||
# v0.7.0 - 2021/06/12 |
||||
|
||||
### Support context for MarshalJSON and UnmarshalJSON ( #248 ) |
||||
|
||||
* json.MarshalContext(context.Context, interface{}, ...json.EncodeOption) ([]byte, error) |
||||
* json.NewEncoder(io.Writer).EncodeContext(context.Context, interface{}, ...json.EncodeOption) error |
||||
* json.UnmarshalContext(context.Context, []byte, interface{}, ...json.DecodeOption) error |
||||
* json.NewDecoder(io.Reader).DecodeContext(context.Context, interface{}) error |
||||
|
||||
```go |
||||
type MarshalerContext interface { |
||||
MarshalJSON(context.Context) ([]byte, error) |
||||
} |
||||
|
||||
type UnmarshalerContext interface { |
||||
UnmarshalJSON(context.Context, []byte) error |
||||
} |
||||
``` |
||||
|
||||
### Add DecodeFieldPriorityFirstWin option ( #242 ) |
||||
|
||||
In the default behavior, go-json, like encoding/json, will reflect the result of the last evaluation when a field with the same name exists. I've added new options to allow you to change this behavior. `json.DecodeFieldPriorityFirstWin` option reflects the result of the first evaluation if a field with the same name exists. This behavior has a performance advantage as it allows the subsequent strings to be skipped if all fields have been evaluated. |
||||

||||
|
||||
### Fix encoder |
||||
|
||||
- Fixed handling of MarshalJSON of function type |
||||
|
||||
### Fix decoding of slice of pointer type |
||||
|
||||
If there is a pointer value, go-json will use it. (This behavior is necessary to achieve the ability to prioritize pre-filled values). However, since slices are reused internally, there was a bug that referred to the previous pointer value. Therefore, it is not necessary to refer to the pointer value in advance for the slice element, so we explicitly initialize slice element by `nil`. |
||||
|
||||
# v0.4.8 - 2021/3/21 |
||||
|
||||
### Reduce memory usage at compile time |
||||

||||
* Add many test cases for encoder |
||||
* Fix composite type ( slice/array/map ) |
||||
* Fix pointer types |
||||
* Fix encoding of MarshalJSON or MarshalText or json.Number type |
||||
|
||||

||||
* Change package layout for reducing memory usage at compile |
||||
* Remove anonymous and only operation |
||||
* Remove root property from encodeCompileContext and opcode |
||||
|
||||
### Fix CI |
||||
|
||||
* Add Go 1.16 |
||||
* Remove Go 1.13 |
||||
* Fix `make cover` task |
||||
|
||||
### Number/Delim/Token/RawMessage use the types defined in encoding/json by type alias |
||||
|
||||
# v0.4.7 - 2021/02/22 |
||||
|
||||
### Fix decoder |
||||

||||
|
||||
### Remove unnecessary optype |

// The angle brackets "<" and ">" are escaped to "\u003c" and "\u003e"

// Ampersand "&" is also escaped to "\u0026" for the same reason.
|

// This escaping can be disabled using an Encoder that had SetEscapeHTML(false)

//
|
||||
// Array and slice values encode as JSON arrays, except that
|
||||
// []byte encodes as a base64-encoded string, and a nil slice
|
||||
// encodes as the null JSON value.
|
||||
//
|
||||
// Struct values encode as JSON objects.
|
||||
// Each exported struct field becomes a member of the object, using the
|
||||
// field name as the object key, unless the field is omitted for one of the
|
||||
// reasons given below.
|
||||
//
|
||||
// The encoding of each struct field can be customized by the format string
|
||||
// stored under the "json" key in the struct field's tag.
|
||||
// The format string gives the name of the field, possibly followed by a
|
||||
// comma-separated list of options. The name may be empty in order to
|
||||
// specify options without overriding the default field name.
|
||||
//
|
||||
// The "omitempty" option specifies that the field should be omitted
|
||||
// from the encoding if the field has an empty value, defined as
|
||||
// false, 0, a nil pointer, a nil interface value, and any empty array,
|
||||
// slice, map, or string.
|
||||
//
|
||||
// As a special case, if the field tag is "-", the field is always omitted.
|
||||
// Note that a field with name "-" can still be generated using the tag "-,".
|
||||
//
|
||||
// Examples of struct field tags and their meanings:
|
||||
//
|
||||
// // Field appears in JSON as key "myName".
|
||||
// Field int `json:"myName"`
|
||||
//
|
||||
// // Field appears in JSON as key "myName" and
|
||||
// // the field is omitted from the object if its value is empty,
|
||||
// // as defined above.
|
||||
// Field int `json:"myName,omitempty"`
|
||||
//
|
||||
// // Field appears in JSON as key "Field" (the default), but
|
||||
// // the field is skipped if empty.
|
||||
// // Note the leading comma.
|
||||
// Field int `json:",omitempty"`
|
||||
//
|
||||
// // Field is ignored by this package.
|
||||
// Field int `json:"-"`
|
||||
//
|
||||
// // Field appears in JSON as key "-".
|
||||
// Field int `json:"-,"`
|
||||
//
|
||||
// The "string" option signals that a field is stored as JSON inside a
|
||||
// JSON-encoded string. It applies only to fields of string, floating point,
|
||||
// integer, or boolean types. This extra level of encoding is sometimes used
|
||||
// when communicating with JavaScript programs:
|
||||
//
|
||||
// Int64String int64 `json:",string"`
|
||||
//
|
||||
// The key name will be used if it's a non-empty string consisting of
|
||||
// only Unicode letters, digits, and ASCII punctuation except quotation
|
||||
// marks, backslash, and comma.
|
||||
//
|
||||
// Anonymous struct fields are usually marshaled as if their inner exported fields
|
||||
// were fields in the outer struct, subject to the usual Go visibility rules amended
|
||||
// as described in the next paragraph.
|
||||
// An anonymous struct field with a name given in its JSON tag is treated as
|
||||
// having that name, rather than being anonymous.
|
||||
// An anonymous struct field of interface type is treated the same as having
|
||||
// that type as its name, rather than being anonymous.
|
||||
//
|
||||
// The Go visibility rules for struct fields are amended for JSON when
|
||||
// deciding which field to marshal or unmarshal. If there are
|
||||
// multiple fields at the same level, and that level is the least
|
||||
// nested (and would therefore be the nesting level selected by the
|
||||
// usual Go rules), the following extra rules apply:
|
||||
//
|
||||
// 1) Of those fields, if any are JSON-tagged, only tagged fields are considered,
|
||||
// even if there are multiple untagged fields that would otherwise conflict.
|
||||
//
|
||||
// 2) If there is exactly one field (tagged or not according to the first rule), that is selected.
|
||||
//
|
||||
// 3) Otherwise there are multiple fields, and all are ignored; no error occurs.
|
||||
//
|
||||
// Handling of anonymous struct fields is new in Go 1.1.
|
||||
// Prior to Go 1.1, anonymous struct fields were ignored. To force ignoring of
|
||||
// an anonymous struct field in both current and earlier versions, give the field
|
||||
// a JSON tag of "-".
|
||||
//
|
||||
// Map values encode as JSON objects. The map's key type must either be a
|
||||
// string, an integer type, or implement encoding.TextMarshaler. The map keys
|
||||
// are sorted and used as JSON object keys by applying the following rules,
|
||||
// subject to the UTF-8 coercion described for string values above:
|
||||
// - string keys are used directly
|
||||
// - encoding.TextMarshalers are marshaled
|
||||
// - integer keys are converted to strings
|
||||
//
|
||||
// Pointer values encode as the value pointed to.
|
||||
// A nil pointer encodes as the null JSON value.
|
||||
//
|
||||
// Interface values encode as the value contained in the interface.
|
||||
// A nil interface value encodes as the null JSON value.
|
||||
//
|
||||
// Channel, complex, and function values cannot be encoded in JSON.
|
||||
// Attempting to encode such a value causes Marshal to return
|
||||
// an UnsupportedTypeError.

//
|

// To unmarshal JSON into a pointer, Unmarshal first handles the case of

// the JSON being the JSON literal null. In that case, Unmarshal sets
|
||||
// the pointer to nil. Otherwise, Unmarshal unmarshals the JSON into
|
||||
// the value pointed at by the pointer. If the pointer is nil, Unmarshal
|
||||
// allocates a new value for it to point to.
|
||||
//
|
||||
// To unmarshal JSON into a value implementing the Unmarshaler interface,
|
||||
// Unmarshal calls that value's UnmarshalJSON method, including
|
||||
// when the input is a JSON null.
|
||||
// Otherwise, if the value implements encoding.TextUnmarshaler
|
||||
// and the input is a JSON quoted string, Unmarshal calls that value's
|
||||
// UnmarshalText method with the unquoted form of the string.
|
||||
//
|
||||
// To unmarshal JSON into a struct, Unmarshal matches incoming object
|
||||
// keys to the keys used by Marshal (either the struct field name or its tag),
|
||||
// preferring an exact match but also accepting a case-insensitive match. By
|
||||
// default, object keys which don't have a corresponding struct field are
|
||||
// ignored (see Decoder.DisallowUnknownFields for an alternative).
|
||||
//
|
||||
// To unmarshal JSON into an interface value,
|
||||
// Unmarshal stores one of these in the interface value:
|
||||
//
|
||||
// bool, for JSON booleans
|
||||
// float64, for JSON numbers
|
||||
// string, for JSON strings
|
||||
// []interface{}, for JSON arrays
|
||||
// map[string]interface{}, for JSON objects
|
||||
// nil for JSON null
|
||||
//
|
||||
// To unmarshal a JSON array into a slice, Unmarshal resets the slice length
|
||||
// to zero and then appends each element to the slice.
|
||||
// As a special case, to unmarshal an empty JSON array into a slice,
|
||||
// Unmarshal replaces the slice with a new empty slice.
|
||||
//
|
||||
// To unmarshal a JSON array into a Go array, Unmarshal decodes
|
||||
// JSON array elements into corresponding Go array elements.
|
||||
// If the Go array is smaller than the JSON array,
|
||||
// the additional JSON array elements are discarded.
|
||||
// If the JSON array is smaller than the Go array,
|
||||
// the additional Go array elements are set to zero values.
|
||||
//
|
||||
// To unmarshal a JSON object into a map, Unmarshal first establishes a map to
|
||||
// use. If the map is nil, Unmarshal allocates a new map. Otherwise Unmarshal
|
||||
// reuses the existing map, keeping existing entries. Unmarshal then stores
|
||||
// key-value pairs from the JSON object into the map. The map's key type must
|
||||
// either be any string type, an integer, implement json.Unmarshaler, or
|
||||
// implement encoding.TextUnmarshaler.
|
||||
//
|
||||
// If a JSON value is not appropriate for a given target type,
|
||||
// or if a JSON number overflows the target type, Unmarshal
|
||||
// skips that field and completes the unmarshaling as best it can.
|
||||
// If no more serious errors are encountered, Unmarshal returns
|
||||
// an UnmarshalTypeError describing the earliest such error. In any

// case, it's not guaranteed that all the remaining fields following

// the problematic one will be unmarshaled into the target object.

// on the value and produces no error.
