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.

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(vals []EncDatum, directions []encoding.Direction, key []byte) ([]byte, error)

	keyPrefix []byte,
) (key []byte, containsNull bool, err error)

EncodeIndexKey creates a key by concatenating keyPrefix with the encodings of the columns in the index.

If a table or index is interleaved, `encoding.encodedNullDesc` is used in place of the family id (a varint) to signal the next component of the key. An example of one level of interleaving (a parent): /<parent_table_id>/<parent_index_id>/<field_1>/<field_2>/NullDesc/<table_id>/<index_id>/<field_3>/<family>

Returns the key and whether any of the encoded values were NULLs.

Note that ExtraColumnIDs are not encoded, so the result isn't always a full index key.

EncodeSecondaryIndexes encodes key/values for the secondary indexes. colMap maps ColumnIDs to indices in `values`. secondaryIndexEntries is the return value (passed as a parameter so the caller can reuse between rows) and is expected to be the same length as indexes.

func EncodeTableKey

func EncodeTableKey(b []byte, val parser.Datum, dir encoding.Direction) ([]byte, error)

func NewStatementCompletionUnknownError

func NewStatementCompletionUnknownError(err *roachpb.AmbiguousResultError) error

NewStatementCompletionUnknownError creates an error with the corresponding pg code. This is used to inform the client that it's unknown whether a statement succeeded or not. Of particular interest to clients is when this error is returned for a statement outside of a transaction or for a COMMIT/RELEASE SAVEPOINT - there manual inspection may be necessary to check whether the statement/transaction committed. When this is returned for other transactional statements, the transaction has been rolled back (like it is for any errors).

NOTE(andrei): When introducing this error, I haven't verified the exact conditions under which Postgres returns this code, nor its relationship to code CodeTransactionResolutionUnknownError. I couldn't find good documentation on these codes.

-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).

func (EncDatumRow) CompareToDatums

func (r EncDatumRow) CompareToDatums(

type RowContainer

type RowContainer struct {
	// contains filtered or unexported fields
}

RowContainer is a container for rows of Datums which tracks the approximate amount of memory allocated for row data. Rows must be added using AddRow(); once the work is done the Close() method must be called to release the allocated memory.

TODO(knz): this does not currently track the amount of memory used for the outer array of Datums references.

func NewRowContainer

func NewRowContainer(acc mon.BoundAccount, ti ColTypeInfo, rowCapacity int) *RowContainer

NewRowContainer allocates a new row container.

The acc argument indicates where to register memory allocations by this row container. Should probably be created by Session.makeBoundAccount() or Session.TxnState.makeBoundAccount().

The rowCapacity argument indicates how many rows are to be expected; it is used to pre-allocate the outer array of row references, in the fashion of Go's capacity argument to the make() function.

Note that we could, but do not (yet), report the size of the row container itself to the monitor in this constructor. This is because the various planNodes are not (yet) equipped to call Close() upon encountering errors in their constructor (all nodes initializing a RowContainer there) and SetLimitHint() (for sortNode which initializes a RowContainer there). This would be rather error-prone to implement consistently and hellishly difficult to test properly. The trade-off is that very large table schemas or column selections could cause unchecked and potentially dangerous memory growth.

func (*RowContainer) AddRow

func (c *RowContainer) AddRow(ctx context.Context, row parser.Datums) (parser.Datums, error)

AddRow attempts to insert a new row in the RowContainer. The row slice is not used directly: the Datum values inside the Datums are copied to internal storage. Returns an error if the allocation was denied by the MemoryMonitor.

func (*RowContainer) At

func (c *RowContainer) At(i int) parser.Datums

func (c *RowContainer) Close(ctx context.Context)

Close releases the memory associated with the RowContainer.

func (*RowContainer) Init

func (c *RowContainer) Init(acc mon.BoundAccount, ti ColTypeInfo, rowCapacity int)

Init can be used instead of NewRowContainer if we have a RowContainer that is already part of an on-heap structure.

func (*RowContainer) Len

func (c *RowContainer) Len() int

Replace substitutes one row for another. This does query the MemoryMonitor to determine whether the new row fits the allowance.

func (*RowContainer) Swap

func (c *RowContainer) Swap(i, j int)

Swap exchanges two rows. Used for sorting.

The returned RowUpdater contains a FetchCols field that defines the expectation of which values are passed as oldValues to UpdateRow. Any column passed in requestedCols will be included in FetchCols.

func (*RowUpdater) IsColumnOnlyUpdate

func (ru *RowUpdater) IsColumnOnlyUpdate() bool

IsColumnOnlyUpdate returns true if this RowUpdater is only updating column data (in contrast to updating the primary key or other indexes).

func (*RowUpdater) UpdateRow

func (ru *RowUpdater) UpdateRow(
	ctx context.Context,
	b *client.Batch,
	oldValues []parser.Datum,
	updateValues []parser.Datum,
	traceKV bool,
) ([]parser.Datum, error)

UpdateRow adds to the batch the kv operations necessary to update a table row with the given values.

The row corresponding to oldValues is updated with the ones in updateValues. Note that updateValues only contains the ones that are changing.

The return value is only good until the next call to UpdateRow.

type TableDescriptor

type TableDescriptor struct {
	// The table name. It should be normalized using sqlbase.NormalizeName()

	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

type TableDescriptors

type TableDescriptors []*TableDescriptor

TableDescriptors is a sortable list of *TableDescriptors.

func (TableDescriptors) Len

func (t TableDescriptors) Len() int

type TableLookup

type TableLookup struct {
	Table    *TableDescriptor
	IsAdding bool
}

TableLookup is the value type of TableLookupsByID: An optional table descriptor, populated when the table is public/leasable, and an IsAdding flag.

type TableLookupsByID

type TableLookupsByID map[ID]TableLookup

TableLookupsByID maps table IDs to looked up descriptors or, for tables that exist but are not yet public/leasable, entries with just the IsAdding flag.

func TablesNeededForFKs

func TablesNeededForFKs(table TableDescriptor, usage FKCheck) TableLookupsByID

TablesNeededForFKs calculates the IDs of the additional TableDescriptors that will be needed for FK checking delete and/or insert operations on `table`.

NB: the returned map's values are *not* set -- higher level calling code, eg in planner, should fill the map's values by acquiring leases. This function is essentially just returning a slice of IDs, but the empty map can be filled in place and reused, avoiding a second allocation.

type UserPrivilegeString
