New read-only system variables (set at startup, need --log-error): * log_error_file_buffer_size: error log buffer size, default 0 (off) * log_error_file_rotate_size: rotate the error log above this size, default 1073741824 * log_error_file_rotations: number of rotated files kept, default 0 Changes: * Write the error log through the logger service, which batches writes in an in-memory buffer, when log_error_file_buffer_size is set. * print_buffer_to_file() uses one static buffer, allocated on first use (MAX_LOG_BUFFER_SIZE+1), grown as needed and freed at shutdown. * vprint_msg_to_log() writes lines longer than 1024 bytes in full, up to 1 MB. * Galera messages use the same error log path. Debug messages are written only if wsrep_debug is set. * Add mtr tests for the three variables, buffered logging, rotation and long lines.

MariaDB: The innovative open source database
MariaDB was designed as a drop-in replacement for MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:
https://mariadb.com/docs/release-notes
Getting the code, building it and testing it
Refer to the following guide: https://mariadb.org/get-involved/getting-started-for-developers/get-code-build-test/ which outlines how to build the source code correctly and run the MariaDB testing framework, as well as which branch to target for your contributions.
