C.3.16. Changements de la version 4.0.10 (29 janvier 2003)

Fonctionnalité ajoutée ou modifiée :

  • Added option --log-error[=file_name] to mysqld_safe and mysqld. This option will force all error messages to be put in a log file if the option --console is not given. On Windows --log-error is enabled as default, with a default name of host_name.err if the name is not specified.

  • Changed some things from Warning: to Note: in the log files.

  • The mysqld server should now compile on NetWare.

  • Added optimization that if one does GROUP BY ... ORDER BY NULL then result is not sorted.

  • New --ft-stopword-file command-line option for mysqld to replace/disable the built-in stopword list that is used in full-text searches. See Section 13.5.3.18, « Syntaxe de SHOW VARIABLES ».

  • Changed default stack size from 64K to 192K; This fixes a core dump problem on Red Hat 8.0 and other systems with a glibc that requires a stack size larger than 128K for gethostbyaddr() to resolve a hostname. You can fix this for earlier MySQL versions by starting mysqld with --thread-stack=192K.

  • Added mysql_waitpid to the binary distribution and the MySQL-client RPM subpackage (required for mysql-test-run).

  • Renamed the main MySQL RPM package to MySQL-server. When updating from an older version, MySQL-server.rpm will simply replace MySQL.rpm.

  • If a slave is configured with replicate_wild_do_table=db.% or replicate_wild_ignore_table=db.%, these rules will be applied to CREATE/DROP DATABASE, too.

  • Added timeout value for MASTER_POS_WAIT().

Bogues corrigés :

  • Fixed initialization of the random seed for newly created threads to give a better rand() distribution from the first call.

  • Fixed a bug that caused mysqld to hang when a table was opened with the HANDLER command and then dropped without being closed.

  • Fixed bug in logging to binary log (which affects replication) a query that inserts a NULL in an AUTO_INCREMENT column and also uses LAST_INSERT_ID().

  • Fixed an unlikely bug that could cause a memory overrun when using ORDER BY constant_expression.

  • Fixed a table corruption in myisamchk's parallel repair mode.

  • Fixed bug in query cache invalidation on simple table renaming.

  • Fixed bug in mysqladmin --relative.

  • On some 64-bit systems, show status reported a strange number for Open_files and Open_streams.

  • Fixed incorrect number of columns in EXPLAIN on empty table.

  • Fixed bug in LEFT JOIN that caused zero rows to be returned in the case the WHERE condition was evaluated as FALSE after reading const tables. (Unlikely condition).

  • FLUSH PRIVILEGES didn't correctly flush table/column privileges when mysql.tables_priv is empty.

  • Fixed bug in replication when using LOAD DATA INFILE one a file that updated an AUTO_INCREMENT column with NULL or 0. This bug only affected MySQL 4.0 masters (not slaves or MySQL 3.23 masters). Note: If you have a slave that has replicated a file with generated AUTO_INCREMENT columns then the slave data is corrupted and you should reinitialize the affected tables from the master.

  • Fixed possible memory overrun when sending a BLOB value larger than 16M to the client.

  • Fixed incorrect error message when setting a NOT NULL column to an expression that returned NULL.

  • Fixed core dump bug in str LIKE "%other_str%" where str or other_str contained characters >= 128.

  • Fixed bug: When executing on master LOAD DATA and InnoDB failed with table full error the binary log was corrupted.
