RMariaDB 1.2.2

Features

• dbAppendTable() accepts Id (#262, @renkun-ken).

• dbConnect() gains reconnect argument that sets the MYSQL_OPT_RECONNECT option (#261, @renkun-ken).

Features

• Upgrade to mariadb-connector-c 3.2.5 on Windows, with built-in support for the caching_sha2_password plugin (#134, #248, @jeroen).

Internal

• Make method definition more similar to S3. All setMethod() calls refer to top-level functions (#250).

RMariaDB 1.2.0

Features

• BLOBs are returned as blob::blob() objects (#126, #243).
• dbWriteTable() and dbAppendTable() are much faster thanks to LOAD DATA LOCAL INFILE. To activate this, load_data_local_infile = TRUE must be passed to dbConnect(). The readr package is required (#11, #223).

Bug fixes

• Writing dates prior to 1970 no longer crashes on Windows (#232, #245).

Internal

• Add test for reading and writing JSON data type as string (#127, #246).
• Update for compatibility with DBItest 1.7.2 (#228).

RMariaDB 1.1.2

Licensing

• RMariaDB is now licensed under the MIT license (#213).

Features

• dbConnect() normalizes all input paths (#197, @twentytitus).
• dbDataType() returns TIME(6) for difftime, and DATETIME(6) for POSIXt columns, to create columns with microsecond precision by default (#214).

Documentation

• Now referring to the libmariadb-dev Debian/Ubuntu package in documentation and configuration scripts (#219).
• ?dbConnect gains a section on secure passwords and the .mylogin.cnf file (#156).

Internal

• Test MySQL and MariaDB Server and client libraries in all combinations on GitHub Actions (#224).

• The configure script now queries the RMARIADB_FORCE_MARIADBCONFIG and RMARIADB_FORCE_MYSQLCONFIG environment variables to force use of mariadb_config or mysql_config, respectively (#218).

RMariaDB 1.1.1

Features

• BIT(1) columns are returned as logical (#84). NULL is mapped to NA for bit(1) columns (#201, @dirkschumacher).
• dbConnect() now supports timezone_out argument. Explicitly setting timezone to NULL tries to detect the database time zone (#116).

Bug fixes

• Timestamp values are now written correctly if the database connection uses a time zone other than UTC. Deviations still might occur at DST boundaries, therefore it is still safer to use UTC as the database connection (#116).
• Timestamp roundtrip no longer fails on Windows i386 (#117).

Internal

• Remove BH dependency by inlining the header files (#208).
