What's Changed

Major changes

  • Use SET NAMES charset COLLATE collation. by @​methane in #​1437

    • Older go-mysql-driver used collation_id in the handshake packet. But it caused collation mismatch in some situation.
    • If you don't specify charset nor collation, go-mysql-driver sends SET NAMES utf8mb4 for new connection. This uses server's default collation for utf8mb4.
    • If you specify charset, go-mysql-driver sends SET NAMES <charset>. This uses the server's default collation for <charset>.
    • If you specify collation and/or charset, go-mysql-driver sends SET NAMES charset COLLATE collation.
  • PathEscape dbname in DSN. by @​methane in #​1432

    • This is backward incompatible in rare case. Check your DSN.
  • Drop Go 1.13-17 support by @​methane in #​1420

    • Use Go 1.18+
  • Parse numbers on text protocol too by @​methane in #​1452

    • When text protocol is used, go-mysql-driver passed bare []byte to database/sql for avoid unnecessary allocation and conversion.
    • If user specified *any to Scan(), database/sql passed the []byte into the target variabe.
    • This confused users because most user doesn't know when text/binary protocol used.
    • go-mysql-driver 1.8 converts integer/float values into int64/double even in text protocol. This doesn't increase allocation compared to []byte and conversion cost is negilible.
  • New options start using the Functional Option Pattern to avoid increasing technical debt in the Config object. Future version may introduce Functional Option for existing options, but not for now.
