Connector/R2DBC 1.1.4 Release Notes

Connector/R2DBC 1.1.4 is a Stable (GA) release of MariaDB Connector/R2DBC, released on 2023-03-27

Release date: 27 Mar 2023

MariaDB Connector/R2DBC 1.1.4 is a (GA) release.

This release is compatible with specification.

When MariaDB Connector/R2DBC 1.1.4 connects to a pre-existing TLS tunnel, host verification can be disabled. ()

The behavior can be configured using the , which defaults to false.

When the sslMode connection parameter is set to , host verification can be disabled by setting sslTunnelDisableHostVerification to true.

For example:

When the is enabled, prepared statements can use the text protocol. (R2DBC-85)
- To use the text protocol in this scenario, prefix the query string with /text/ when creating the prepared statement.
- For example, to use the text protocol with the native R2DBC API:

MariaDB Connector/R2DBC 1.1.4 adds support for decoding TIMESTAMP and DATE "zero" date values ('0000-00-00') from MariaDB Xpand. (R2DBC-83)
- In previous releases, when the connector received a "zero" date value from Xpand, the value could not be decoded and the following error would be raised:

When the is enabled, MEDIUMINT values are not properly decoded. (R2DBC-76)
- In Connector/R2DBC 1.1.2 and 1.1.3, when the binary protocol is used, the last byte of a MEDIUMINT value is not read from a result-set, so remaining values from the same row are read incorrectly.
When the Statement.returnGeneratedValues() method is called when connected to a version of MariaDB Server prior to 10.5, an error is raised. (R2DBC-77)
- In previous releases, the following error would be raised:

MariaDB Connector/R2DBC's internal statement parser improperly classifies user-defined variables in SELECT statements as named statement parameters. (R2DBC-79)
- In previous releases, the @amount token in the query below would be classified as a named statement parameter, instead of a user-defined variable.

Starting with this release, the internal statement parser can distinguish between user-defined variables and named statement parameters.
When a ConnectionFactory is used to construct a connection string from a ConnectionFactoryOptions instance, the restrictedAuth, rsaPublicKey, cachingRsaPublicKey, and allowPublicKeyRetrieval connection parameters are not properly parsed. (R2DBC-81)
When a server does not advertise the CLIENT_SESSION_TRACK capability (such as old versions of MariaDB Server, MySQL, and MariaDB Xpand), the MariadbConnection.getTransactionIsolationLevel() and MariadbConnection.setTransactionIsolationLevel(IsolationLevel isolationLevel) methods do not properly get or set the transaction isolation level. (R2DBC-82)
