MariaDB Connector/C 3.4.2 Release Notes

Note: This page describes features in the source repository for the MariaDB Connector/C. There are currently no official packages or binaries available for download which contain the version of the driver described here. If you want to try out any of the new features described here you will need to get and compile the code yourself.

This is a Stable (GA) release of MariaDB Connector/C, formerly known as MariaDB Client Library for C.

For a description of this library see the MariaDB Connector/C page.

Notable Changes

  • Added option MARIADB_TLS_VERIFY_STATUS to retrieve status of peer certificate validation via mariadb_get_infov().
  • CONC-690: Due to required cryptographic functions that are part of the TLS crypto libraries the option WITH_SSL=OFF (disabling TLS/SSL) is no longer supported and will result in a build error.
  • CONC-724: Added option MARIADB_OPT_TLS_VERIFICATION_CALLBACK to specify a callback function for peer certificate testing.
  • Man pages are no longer stored in github repository. They can be build with cmake option -DWITH_DOCS=ON (requires pyhon 3 and pandoc).
  • If the environment variable MARIADB_TLS_DISABLE_PEER_VERIFICATION was set, the peer certificate verification will be skipped.
  • CONC-717: Added windows support for the parsec authentication plugin, a new plugin added to MariaDB Server 11.6

Issues fixed:

  • CONC-712: Skip host name verification on local connections
  • CONC-731: Wrong error message if incorrect fingerprint was specified
  • CONC-732: Always set verification callback function, even if peer certificate validation is disabled (OpenSSL)
