News - 4.x

Release 4.10 - 2015-01-29

This release has a bug fix for unique index. If you're using unique index in storage mode, your data may be broken. If you're using unique index in storage mode, we recommend to upgrade to this version and re-create your unique indexes.

Here are SQL statements to re-create your indexes including unique indexes:

ALTER TABLE ${YOUR_TABLE} DISABLE KEYS;
ALTER TABLE ${YOUR_TABLE} ENABLE KEYS;

You may get "duplicated record" error on ENABLE KEYS. If you get the error, please confirm your data carefully and fix the duplication.

Here are broken data scenario:

• An unique index is created.
• Insert data.
• Insert duplicated data. It's reported as an error.
• Insert duplicated data again. It can be inserted. It breaks unique consistency.

Improvements

• [storage] Supported static index construction in FULLTEXT INDEX comment with 'table "XXX"'. Execute DISABLE KEYS, then ENABLE KEYS for static index construction. [Reported by Naoya Murakami]
• [rpm][centos] Built with MySQL 5.6.22 on CentOS 7. [groonga-dev,03047] [Reported by Hiroshi Kagami]
• [rpm][centos] Built with MariaDB 5.5.40-2 on CentOS 7.
• [storage][mysql56] Supported to report duplicated error for ADD UNIQUE INDEX. [Reported by kazeburo]

Fixes

• [storage] Fixed a bug that referenced table is accidentally removed on error. This means that index creation is failed for FULLTEXT INDEX comment with 'table "terms"', "terms" table can be removed on error.
• [storage] Fixed a bug that duplicated entry is removed in unique index when duplicated error is occurred. This bug makes consistency of indexes broken, so recommended to recreate existing indexes again after upgrading Mroonga. [Reported by kazeburo]
• [storage] Fixed a bug that INSERT ON DUPLICATE KEY UPDATE is broken. This bug may change existing other records by executing update fallback when insert error occurred. [Reported by kazeburo]
