Notable Changes

This is the first alpha release in the MariaDB 10.1 series.

Notable changes of this release include:

  • InnoDB/XtraDB
    • MDEV-6075, Allow > 16K pages on InnoDB - InnoDB now allows page size to be configured as 16K, 32K and 64K. Note that single row size must be < 16K. This feature will allow especially more blob columns to be created.
    • MDEV-5335, Force PK option - Added a new dynamic configuration variable innodb_force_primary_key default off. If option is true, create table without primary key or unique key where all keyparts are NOT NULL is not accepted. Instead an error message is printed. Variable value can be changed with set global innodb_force_primary_key = <value>.
  • Security
    • MDEV-5730, enhance security using special compilation options - MariaDB is now compiled with security hardening options by default. It is an additional protection layer that makes new, yet unknown, security vulnerabilities more difficult to exploit.
  • Storage Engine functionality
    • MDEV-6107, merge default_tmp_storage_engine - Added default_tmp_storage_engine server variable and the command line option.
    • MDEV-4260, Don't create frm files for temporary tables - Temporary tables no longer create frm files on disk. Which means that if the temporary table is created in the MEMORY engine, it will not touch the disk at all.
    • The ARCHIVE storage engine is no longer enabled by default, and the plugin needs to be specifically enabled.
    • The BLACKHOLE storage engine is no longer enabled by default, and the plugin needs to be specifically enabled.
  • Optimizer
    • MDEV-406, ANALYZE $stmt - Check how close the optimizer's estimates about the query plan are to the reality.
  • Administration
    • MDEV-6248, GUI-friendly cmake options to enable/disable plugins - MariaDB now uses PLUGIN_xxx cmake options to enable or disable plugins, not a combination of WITH_xxx, WITHOUT_xxx, WITH_PLUGINX_xxx, WITHOUT_PLUGIN_xxx, WITH_xxx_STORAGE_ENGINE, WITHOUT_xxx_STORAGE_ENGINE. See Specifying What Plugins to Build.
  • Improvements from WebScaleSQL
    • Fix errors detected by ASan at compile time - Not merged but ASan was run against MariaDB. It generated the following:
      • MDEV-6314 - Compile/run MariaDB with ASan (fixed in 10.0.13)
      • MDEV-6315 - TokuDB: ERROR: AddressSanitizer: attempting to call malloc_usable_size() for pointer which is not owned: 0x601200008f80 (not fixed)
      • MDEV-6323 - ‘explain_node’ may be used uninitialized in this function (not fixed)
      • MDEV-6325 - TokuDB: warning: ‘do_commit’ may be used uninitialized in this function (not fixed)
    • MDEV-6329, Fix errors detected by ASan at runtime. Merged to 5.5.39.
    • Use single quotes for perl paths, in case of special symbols. Merged to 10.0.13.
    • Stop spawning dummy threads on client library initialization. Merged to 10.0.13.
  • Performance
