README ¶

`package dcrpg`

The dcrpg package provides types and functions for manipulating PostgreSQL tables, and storing blocks, transactions, inputs, and outputs.

Supported Database Software

PostgreSQL versions 10.5 to 11.x are fully supported. The bulk of the testing and performance optimization is done with PostgreSQL in mind.

Experimental support for CockroachDB was added for ecrdata 5.0. However, compared to a well-configure PostgreSQL backend, CoackroachDB performance is suboptimal. See the CockroachDB support issue for more information.

Performance and Bulk Loading

When performing a bulk data import, it is wise to first drop any existing indexes and create them again after insertion is completed. Functions are provided to create and drop the indexes.

PostgreSQL performance will be poor, particularly during bulk import, unless synchronous transaction commits are disabled via the synchronous_commit = off configuration setting in your postgresql.conf. There are numerous PostreSQL tuning settings, but a quick suggestion for your system can be provided byPgTune. During initial table population, it is also OK to turn off full page writes, and possibly fsync, but change these two options back after initial sync.

Especially during normal operation, it is important to set autovacuum = on. For fast queries, it is critical to have regular table statistics collected by the autovacuum process.

func CheckBadSpentLiveTickets(ctx context.Context, db *sql.DB) (ids []uint64, txHashes []string, spendTypes []int16, err error)

CheckBadSpentLiveTickets checks the tickets table for tickets with live pool status but not unspent status. This indicates likely database corruption.

func CheckBadVotedTickets ¶

func CheckBadVotedTickets(ctx context.Context, db *sql.DB) (ids []uint64, txHashes []string, spendTypes []int16, err error)

CheckBadVotedTickets checks the tickets table for tickets with voted pool status but not voted status. This indicates likely database corruption.

func CheckColumnDataType ¶

func CheckColumnDataType(db *sql.DB, table, column string) (dataType string, err error)

CheckColumnDataType gets the data type of specified table column .

func CheckCurrentTimeZone ¶

func CheckCurrentTimeZone(db *sql.DB) (currentTZ string, err error)

CheckCurrentTimeZone queries for the currently set postgres time zone.

func CheckDefaultTimeZone ¶

func CheckDefaultTimeZone(db *sql.DB) (defaultTZ, currentTZ string, err error)

CheckDefaultTimeZone queries for the default postgres time zone. This is the value that would be observed if postgres were restarted using its current configuration. The currently set time zone is also returned.

func CheckExtraMainchainBlocks ¶

func CheckExtraMainchainBlocks(ctx context.Context, db *sql.DB) (ids, heights []uint64, hashes []string, err error)

CheckExtraMainchainBlocks checks the blocks table for multiple main chain blocks at a given height, which is not possible. The row IDs, block heights, and block hashes are returned. Non-zero length sizes is an indication of database corruption.

func CheckMislabeledInvalidBlocks ¶

func CheckMislabeledInvalidBlocks(ctx context.Context, db *sql.DB) (ids []uint64, hashes []string, err error)

CheckMislabeledInvalidBlocks checks the blocks table for blocks labeled as approved, but for which the following block has specified vote bits that invalidate it. This indicates likely database corruption.

func CheckMislabeledTicketTransactions ¶

func CheckMislabeledTicketTransactions(ctx context.Context, db *sql.DB) (ids []uint64, txTypes []int16, txHashes []string, err error)

CheckMislabeledTicketTransactions checks the transactions table for ticket transactions that also appear in the tickets table, but which do not have the proper tx_type (1) set. This indicates likely database corruption.

func CheckMissingTicketTransactions ¶

func CheckMissingTicketTransactions(ctx context.Context, db *sql.DB) (ids []uint64, txHashes []string, err error)

CheckMissingTicketTransactions checks the tickets table for tickets that do NOT appear in the transactions table at all. This indicates likely database corruption.

func CheckMissingTickets ¶

func CheckMissingTickets(ctx context.Context, db *sql.DB) (ids []uint64, txTypes []int16, txHashes []string, err error)

CheckMissingTickets checks the transactions table for ticket transactions (with tx_type=1) that do NOT appear in the tickets table. This indicates likely database corruption.

func CheckSpentTicketsWithoutSpendInfo ¶

func CheckSpentTicketsWithoutSpendInfo(ctx context.Context, db *sql.DB) (ids, spendHeights, spendTxDbIDs []uint64, err error)

CheckSpentTicketsWithoutSpendInfo checks the tickets table for tickets that are flagged as spent, but which do not have set either a spend height or spending transaction row id. This indicates likely database corruption.

func CheckUnmatchedSpending ¶

func CheckUnmatchedSpending(ctx context.Context, db *sql.DB) (ids []uint64, addresses []string, err error)

CheckUnmatchedSpending checks the addresses table for spending rows where the matching (funding) txhash has not been set. The row IDs and addresses are returned. Non-zero length sizes is an indication of database corruption.

func CheckUnspentTicketsWithSpendInfo ¶

func CheckUnspentTicketsWithSpendInfo(ctx context.Context, db *sql.DB) (ids, spendHeights, spendTxDbIDs []uint64, err error)

CheckUnspentTicketsWithSpendInfo checks the tickets table for tickets that are flagged as unspent, but which have set either a spend height or spending transaction row id. This indicates likely database corruption.

func ClearTestingTable ¶

func ClearTestingTable(db *sql.DB) error

func Connect ¶

func Connect(host, port, user, pass, dbname string) (*sql.DB, error)

Connect opens a connection to a PostgreSQL database. The caller is responsible for calling Close() on the returned db when finished using it. The input host may be an IP address for TCP connection, or an absolute path to a UNIX domain socket. An empty string should be provided for UNIX sockets.
