Functions

func AddColToRows

func AddColToRows(t *testing.T, rs []row.Row, tag uint64, val types.Value) []row.Row

AddColToRows adds a column to all the rows given and returns it. This method relies on the fact that noms_row.SetColVal doesn't need a full schema, just one that includes the column being set.

func AddColumnToSchema

func AddColumnToSchema(sch schema.Schema, col schema.Column) schema.Schema

AddColumnToSchema returns a new schema by adding the given column to the given schema. Will panic on an invalid schema, e.g. tag collision. Note the AddColumnToSchema relies on being called from the engine (GMS) to correctly update defaults. Directly calling this method in Dolt only adds a new column to schema but does not apply the default.

func ConvertToSchema

func ConvertToSchema(sch schema.Schema, rs ...row.Row) []row.Row

Coerces the rows given into the schema given. Only possible if the types are equivalent.

func CreateEnvWithSeedData

func CreateEnvWithSeedData(t *testing.T) *env.DoltEnv

func CreateSchema

func CreateSchema(columns ...schema.Column) schema.Schema

CreateSchema returns a schema from the columns given, panicking on any errors.

func CreateTestDataTable

func CreateTestDataTable(typed bool) (*table.InMemTable, schema.Schema)

func CreateTestEnv

func CreateTestEnv() *env.DoltEnv

func CreateTestTable

func CreateTestTable(t *testing.T, dEnv *env.DoltEnv, tableName string, sch schema.Schema, rs ...row.Row)

CreateTestTable creates a new test table with the name, schema, and rows given.

func MustMap

func MustMap(t *testing.T, vrw types.ValueReadWriter, kv ...types.Value) types.Map

MustMap contructs a types.Map for a slice of alternating key, value types.Value.

func MustRowData

func MustRowData(t *testing.T, ctx context.Context, vrw types.ValueReadWriter, sch schema.Schema, colVals []row.TaggedValues) *types.Map

MustRowData converts a slice of row.TaggedValues into a noms types.Map containing that data.

func MustSchema

func MustSchema(cols ...schema.Column) schema.Schema

MustSchema takes a variable number of columns and returns a schema.

func MustTuple

func MustTuple(vals ...types.Value) types.Tuple

MustMap contructs a types.Tuple for a slice of types.Values.

func NewRow

func NewRow(sch schema.Schema, values ...types.Value) row.Row

Creates a row with the schema given, having the values given. Starts at tag 0 and counts up.

func NewTypedRow

func NewTypedRow(id uuid.UUID, name string, age uint, isMarried bool, title *string) row.Row

func RemoveColumnFromSchema

func RemoveColumnFromSchema(sch schema.Schema, tagToRemove uint64) schema.Schema

RemoveColumnFromSchema returns a new schema with the given tag missing, but otherwise identical. At least one primary column must remain.
