}

SystemAllowedPrivileges describes the allowable privilege lists for each system object. The root user must have the privileges of exactly one of those privilege lists. No user may have more privileges than the root user.

Some system objects were created with different privileges in previous versions of the system. These privileges are no longer "desired" but must still be "allowed," or this version and the previous version with different privileges will be unable to coexist in the same cluster because one version will think it has invalid table descriptors.

The currently-desired privileges (i.e., the privileges with which the object will be created in fresh clusters) must be listed first in the mapped value, followed by previously-desirable but still allowable privileges in any order.

If we supported backwards-incompatible migrations, pruning allowed privileges would require a two-step migration process. First, a new version that allows both must be deployed to all nodes, after which a a migration to upgrade from the old privileges to the new privileges can be run. Only then can a version that removes the old allowed versions be deployed. TODO(benesch): Once we support backwards-incompatible migrations, prune old allowed privileges.

Functions

func CheckColumnType 

func CheckColumnType(col ColumnDescriptor, typ parser.Type, pmap *parser.PlaceholderInfo) error

CheckColumnType verifies that a given value is compatible with the type requested by the column. If the value is a placeholder, the type of the placeholder gets populated.

func CheckValueWidth 

func CheckValueWidth(col ColumnDescriptor, val parser.Datum) error

CheckValueWidth checks that the width (for strings, byte arrays, and bit string) and scale (for decimals) of the value fits the specified column type. Used by INSERT and UPDATE.

func ColumnsSelectors 

func ColumnsSelectors(cols []ColumnDescriptor) parser.SelectExprs

ColumnsSelectors generates Select expressions for cols.

func ConvertBatchError 

func ConvertBatchError(tableDesc *TableDescriptor, b *client.Batch) error

ConvertBatchError returns a user friendly constraint violation error.

func DecodeIndexKey 

func DecodeIndexKey(
	a *DatumAlloc,
	desc *TableDescriptor,
	indexID IndexID,
	vals []EncDatum,
	colDirs []encoding.Direction,
	key []byte,
) ([]byte, bool, error)

DecodeIndexKey decodes the values that are a part of the specified index key. ValTypes is a slice returned from makeKeyVals. The remaining bytes in the index key are returned which will either be an encoded column ID for the primary key index, the primary key suffix for non-unique secondary indexes or unique secondary indexes containing NULL or empty. If the given descriptor does not match the key, false is returned with no error.

func DecodeKeyVals 

func DecodeKeyVals(
	a *DatumAlloc, vals []EncDatum, directions []encoding.Direction, key []byte,
) ([]byte, error)

DecodeKeyVals decodes the values that are part of the key. The decoded values are stored in the vals. If this slice is nil, the direction used will default to encoding.Ascending.

func DecodeTableIDIndexID 

func DecodeTableIDIndexID(key []byte) ([]byte, ID, IndexID, error)

DecodeTableIDIndexID decodes a table id followed by an index id.

func DecodeTableKey 

func DecodeTableKey(
	a *DatumAlloc, valType parser.Type, key []byte, dir encoding.Direction,
) (parser.Datum, []byte, error)

DecodeTableKey decodes a table key/value.

func DecodeTableValue 

func DecodeTableValue(a *DatumAlloc, valType parser.Type, b []byte) (parser.Datum, []byte, error)

DecodeTableValue decodes a value encoded by EncodeTableValue.

func EncDatumRowToDatums 

func EncDatumRowToDatums(datums parser.Datums, row EncDatumRow, da *DatumAlloc) error

EncDatumRowToDatums converts a given EncDatumRow to a Datums.

func EncodeColumns 

func EncodeColumns(
	columnIDs []ColumnID,
	directions directions,
	colMap map[ColumnID]int,
	values []parser.Datum,
	keyPrefix []byte,
) (key []byte, containsNull bool, err error)

EncodeColumns is a version of EncodeIndexKey that takes ColumnIDs and directions explicitly.

func EncodeDatum 

func EncodeDatum(b []byte, d parser.Datum) ([]byte, error)

EncodeDatum encodes a datum (order-preserving encoding, suitable for keys).

func EncodeDatums 

func EncodeDatums(b []byte, d parser.Datums) ([]byte, error)

EncodeDatums encodes a Datums (order-preserving).

func EncodeIndexKey 

func EncodeIndexKey(
	tableDesc *TableDescriptor,
	index *IndexDescriptor,
	colMap map[ColumnID]int,
	values []parser.Datum,
	keyPrefix []byte,

func EncDatumFromEncoded 

func EncDatumFromEncoded(typ ColumnType, enc DatumEncoding, encoded []byte) EncDatum

EncDatumFromEncoded initializes an EncDatum with the given encoded value. The encoded value is stored as a shallow copy, so the caller must make sure the slice is not modified for the lifetime of the EncDatum. SetEncoded wipes the underlying Datum.

func (*EncDatum) Encode 

func (ed *EncDatum) Encode(a *DatumAlloc, enc DatumEncoding, appendTo []byte) ([]byte, error)

Encode appends the encoded datum to the given slice using the requested encoding. Note: DatumEncoding_VALUE encodings are not unique because they can contain a column ID so they should not be used to test for equality.

func (*EncDatum) Encoding 

func (ed *EncDatum) Encoding() (DatumEncoding, bool)

Encoding returns the encoding that is already available (the latter indicated by the bool return value).

func (*EncDatum) EnsureDecoded 

func (ed *EncDatum) EnsureDecoded(a *DatumAlloc) error

EnsureDecoded ensures that the Datum field is set (decoding if it is not).

IsNull returns true if the EncDatum value is NULL. Equivalent to checking if ed.Datum is DNull after calling EnsureDecoded.

func (*EncDatum) IsUnset 

func (ed *EncDatum) IsUnset() bool

IsUnset returns true if SetEncoded or SetDatum were not called.

func (*EncDatum) String 

func (ed *EncDatum) String() string

func (*EncDatum) UnsetDatum 

func (ed *EncDatum) UnsetDatum()

UnsetDatum ensures subsequent IsUnset() calls return false.

type EncDatumRow 

type EncDatumRow []EncDatum

EncDatumRow is a row of EncDatums.

func (EncDatumRow) Compare 

func (r EncDatumRow) Compare(a *DatumAlloc, ordering ColumnOrdering, rhs EncDatumRow) (int, error)

Compare returns the relative ordering of two EncDatumRows according to a ColumnOrdering: 

-1 if the receiver comes before the rhs in the ordering,
+1 if the receiver comes after the rhs in the ordering,
0 if the relative order does not matter (i.e. the two rows have the same
  values for the columns in the ordering).

Note that a return value of 0 does not (in general) imply that the rows are equal; for example, rows [1 1 5] and [1 1 6] when compared against ordering {{0, asc}, {1, asc}} (i.e. ordered by first column and then by second column).

	ParentID ID `protobuf:"varint,4,opt,name=parent_id,json=parentId,casttype=ID" json:"parent_id"`
	// Monotonically increasing version of the table descriptor.
	//
	// Invariants:
	// 1. not more than two subsequent versions of the table
	// descriptor can be leased. This is to make the system
	// easy to reason about, by permiting mutation state
	// changes (reflected in the next version), only when the existing
	// state (reflected in the current version) is present on all
	// outstanding unexpired leases.
	// 2. A schema change command (ALTER, RENAME, etc) never directly
	// increments the version. This allows the command to execute without
	// waiting for the entire cluster to converge to a single version
	// preventing weird deadlock situations. For instance, a transaction
	// with a schema change command might use a descriptor lease that is
	// at version: v - 1, and therefore deadlock when it tries to wait
	// for version: v, in the process of incrementing it to v + 1.
	// Therefore, a schema change command never increments the version,
	// and instead, sets the up_version boolean to notify the schema
	// changer execution engine that runs a future transaction to
	// increment the version.
	//
	// The schema change commands must therefore make *safe* modifications
	// to the table descriptor, such as scheduling long running schema
	// changes through mutations for future execution, or making simple
	// schema changes like RENAME that only modify the table descriptor in a
	// single transaction.
	//
	// Multiple schema changes in the same transaction set up_version.
	// The actual schema change execution that follows a schema change
	// command sees the up_version boolean set, and increments the
	// table version after ensuring that there are no unexpired leases
	// for version - 1. The schema change execution must increment
	// the version before executing future state changes, to ensure
	// that the scheduled mutations made by the original commands are
	// visible on all leases. Multiple schema change mutations can be
	// grouped together on a particular version increment.
	//
	// If schema change commands are safe to run without incrementing
	// the version, why do it later on? We increment the version
	// to ensure that all the nodes renew their leases with the new version

}

The schema update lease. A single goroutine across a cockroach cluster can own it, and will execute pending schema changes for this table. Since the execution of a pending schema change is through transactions, it is legal for more than one goroutine to attempt to execute it. This lease reduces write contention on the schema change.

type TableDescriptor_State 

type TableDescriptor_State int32

State is set if this TableDescriptor is in the process of being added or deleted. A non-public table descriptor cannot be leased. A schema changer observing DROP set will truncate the table and delete the descriptor. It is illegal to transition DROP to any other state. 

const (
	// Not used.
