Changes

In addition the the MariaDB-5.5.43 fixed and improvements, the following fixes and improvements have been made to MariaDB 10.0.18.

Parser

  • Column was quoted with backticks in a function, in a HAVING clause, and it wasn't recognised - fixed now (MDEV-7301).
  • ALTER TABLE with conflicting CHARACTER SET and CONVERT TO CHARACTER SET arguments now reports error (MDEV-7386).
  • Fixed Regression (from 10.0.14): Bit and hex string literals changed column names (MDEV-7629).

Optimizer

Alter Table

  • Some symbols in table name can cause to Error Code: 1050 when created FK. Table name is on filename charset but foreign key identifiers are not. This lead incorrect foreign key identifier number to be used (MDEV-7627).
  • ALTER [ONLINE] TABLE with no options no longer requires a table copy (MDEV-7390).
  • Fixed a case where it was impossible to create copy of table, if table contain default value for timestamp field in sql_mode="NO_ZERO_DATE" (MDEV-7778).

Other SQL Commands

  • INSTALL PLUGIN can now be done in bootstrap mode where authentication is disable (MDEV-7781).
  • Corrected error handing in AES_ENCRYPT/AES_DECRYPT where incorrect data could result in a SSL client connection being terminated (MDEV-7697).
  • Corrected Assertion `status_var.memory_used == 0' failed in THD::THD() on disconnect after executing EXPLAIN for multi-table UPDATE (MDEV-7038).
  • Fixed crash when dropping user within rebuild_role_grants which occurs in some cases in SHOW GRANTS and DROP ROLE (MDEV-7774).
  • SHOW GRANTS doesn't show the password for users that have the password field set, auth_string field empty, plugin=mysql_native_password (MDEV-7985).

Innodb

  • In Debug builds, an assertion could be triggered on really large blobs (MDEV-7754).
  • Fixed segfault when a virtual column used on a innodb table and an index was created on a field after the virtual column (MDEV-7367).
  • Fixed server crash when inserting more rows than available space on disk (MDEV-7685).
  • Make it possible to get innodb internal primary key for wrapper type storage engines (MDEV-7714).

Replication

Platforms

  • PowerPC - fixed Innodb locking issue under high load - (MDEV-7148).
  • BigEndian fails to build in cassandra storage engine (MDEV-7839).
  • Crash when running MariaDB Debug with InnoDB on Windows (MDEV-8079).

Connect Engine

  • CONNECT Engine Column names are not retrieved properly when field values are not latin1 characters (MDEV-7521).
  • Connecting to missing remote table caused error that was re-reported when SHOW TABLE STATUS on a correctly formed table (MDEV-7636).
  • CONNECT returns error 174 on query to MS SQL Server 2012 involving timestamp column when the condition is given as a date literal (MDEV-7840).
  • CONNECT does not work with if(exists(select * from test)) statement in procedures (MDEV-7852).
  • test connect.json fails with valgrind warnings (MDEV-7879)
  • Same query cannot be executed using CONNECT Engine (MDEV-7890).
  • User variable assignment with SET @var = results in ERROR 1148 (42000): CONNECT Unsupported command (MDEV-7616).
  • Remove assertion in delete_or_rename_table that caused crashes on (XML) HTML tables (MDEV-7935).
  • Added UDF Json_Array_Delete (MDEV-7935).
  • Fixed a problem where defining indexes on a connect engine caused wrong results (MDEV-8090).

OQ Graph Engine

Other

  • SSL connections increased from 512 to 1024 bits in Diffie-Hellman exchange to support fips (MDEV-7794).
  • SSL read/write timeouts where a 1000 times too much due to seconds/milliseconds error (MDEV-8096).
  • Tell OpenSSL to use MD5 even if FIPS prohibits it (previously crashed). This is fine as long as we do not use MD5 for cryptographical purposes (md5 is used internally for P_S message digests and for view checksums) (MDEV-7788).
  • initialization of status variables was not invoked for embedded - no corrected (no bug reference. code change)
  • Corrected wrong results with bigint when compiled with gcc 5.0 (MDEV-7973).
  • Fix assertion in Protocol::end_statement where CREATE VIEW occurs after another connection aborted (MDEV-8045).

Client

  • Fixed MariaDB client where it could hang in an infinite loop based on no IO data returned (MDEV-8014).

Test

  • mysql-test-run creates nested links when tests are run with --mem (MDEV-7643).
  • buildbot may leave stale mysqld (MDEV-7659).
  • Fixed test suite failure - mysql-test - SUITE:percona - percona.innodb_sys_index 'xtradb' fails - @@version_comment (MDEV-7692)
  • Fixed test failure in multi_source.multisource (MDEV-7107).
  • Fixed test perfschema.aggregate fails sporadically in buildbot (MDEV-7187)
  • fips: some ssl tests with cipher specified failing as older ciphers removed from libraries (MDEV-7794).
