Release 14.08 - 2024-09-25#
Improvements#
We use CMake for building instead of the GNU Autotools.
Using
configure
is deprecated. We recommend usingcmake
to build from source.Please refer [Others] about how to build from source with
cmake
.
Fixes#
Fixed a bug that
SELECT
returned wrong result when we used multiple primary keys and primary keys includedVARBINARY
orBLOB
type column. [GH-783][Reported by Jérome Perrin]If this bug occurred, the following query retrieved nothing.
CREATE TABLE logs ( id INT, content VARBINARY(256), PRIMARY KEY (id, content) ) ENGINE=Mroonga DEFAULT CHARSET=utf8mb4; INSERT INTO logs(id, content) VALUES (1, 'aaa'); INSERT INTO logs(id, content) VALUES (2, 'bbb'); SELECT * FROM logs WHERE content = 'aaa';
This bug only occurred in Mroonga 14.07.
This bug doesn’t break an index. So, we don’t need to execute
REINDEX
command after this fix.

Disable descending index support [GitHub #764][Reported by Josep Sanz]
If we don’t add support for descending index with MariaDB >= 10.8, Mroonga returns wrong result with descending index. So, we disable descending index support now. However, we may re-try it later.
By the way, if we use descending index with MySQL >= 8.0, MySQL returns error.

Added functionality to output an error when Mroonga’s UDF is used while Mroonga is uninitialized. [MDEV-21166][Reported by Ian Gilfillan.]
Before this fix, using Mroonga’s UDF without initializing Mroonga (not having run
INSTALL PLUGIN mroonga
) would cause a crash. This patch changes the output from a crash to logging an error.
Fixes#
[Wrapper mode] Fixed memory leaks in cases where engines not supporting online DDL are wrapped.
In general, DDL operations like
ALTER TABLE
block access to the target table while in progress to maintain exclusive control. However, some storage engines allow operations on the target table during these operations (they can also be executed exclusively). The capability to operate on a table during such DDL operations is referred to as online DDL.The issue addressed occurs when wrapping storage engines that do not support online DDL in Mroonga’s wrapper mode. It does not occur in storage mode or when using a combination of wrapper mode + InnoDB.
[Storage mode] Fixed a bug causing crashes when inserting into tables with compressed
VARCHAR
orTEXT
columns. [MDEV-31966][Reported by Elena Stepanova.]This issue occurs only in storage mode and not in wrapper mode.
