MySQL logo nieuwe stijlMySQL is een krachtige opensourcedatabaseserver die met name populair is als website- en forumdatabase. Tweakers.net maakt gebruik van MySQL om onder meer gebruikersgegevens, statistieken en diverse review-, meuk- en nieuwsartikelen in op te slaan. Wie de frontpage de afgelopen maanden heeft bijgehouden, weet dat we in die tijd een aantal databasetests online hebben gezet waarin we diverse databasesoftware met elkaar vergelijken, waaronder de 4- en 5-tak van MySQL. Op het forum is vanmorgen de laatste update verschenen van de 4.1-tak van MySQL. De ondersteuning van deze versiereeks eindigt op 31 december 2006, maar voor de Enterprise-aboneehouders kan hier nog drie jaar support aan toegevoegd worden. Versie 4.1.22 wordt geleverd met een waslijst aan veranderingen. Voor de ge´nteresseerden staat deze hieronder gepost:

Functionality added or changed:
  • The mysqld manpage has been reclassified from volume 1 to volume 8. (Bug#21220: http://bugs.mysql.com/21220)
  • MySQL now can do stack dumps on x86_64 and i386/NPTL systems. (Bug#21250: http://bugs.mysql.com/21250)
  • The LOAD DATA FROM MASTER and LOAD TABLE FROM MASTER statements are deprecated. See Section 13.6.2.2, "LOAD DATA FROM MASTER Syntax," for recommended alternatives. (Bug#18822: http://bugs.mysql.com/18822, Bug#9125: http://bugs.mysql.com/9125, Bug#12187: http://bugs.mysql.com/12187, Bug#14399: http://bugs.mysql.com/14399, Bug#15025: http://bugs.mysql.com/15025, Bug#20596: http://bugs.mysql.com/20596)
  • A warning now is issued if the client attempts to set the SQL_LOG_OFF variable without the SUPER privilege. (Bug#16180: http://bugs.mysql.com/16180)
Bugs fixed:
  • Deleting entries from a large MyISAM index could cause index corruption when it needed to shrink. Deletes from an index can happen when a record is deleted, when a key changes and must be moved, and when a key must be un-inserted because of a duplicate key. This can also happen in REPAIR TABLE when a duplicate key is found and in myisamchk when sorting the records by an index. (Bug#22384: http://bugs.mysql.com/22384)
  • Setting myisam_repair_threads caused any repair operation on a MyISAM table to fail to update the cardinality of indexes, instead making them always equal to 1. (Bug#18874: http://bugs.mysql.com/18874)
  • Within a prepared statement, SELECT (COUNT(*) = 1) (or similar use of other aggregate functions) did not return the correct result for statement re-execution. (Bug#21354: http://bugs.mysql.com/21354)
  • DELETE IGNORE could hang for foreign key parent deletes. (Bug#18819: http://bugs.mysql.com/18819)
  • Redundant binary log LAST_INSERT_ID events could be generated; LAST_INSERT_ID(expr) didn't return the value of expr; LAST_INSERT_ID() could return the value generated by the current statement if the call happens after value generation, as in: CREATE TABLE t1 (i INT AUTO_INCREMENT PRIMARY KEY, j INT); INSERT INTO t1 VALUES (NULL, 0), (NULL, LAST_INSERT_ID()); (Bug#21726: http://bugs.mysql.com/21726)
  • FROM_UNIXTIME() did not accept arguments up to POWER(2,31)-1, which it had previously. (Bug#9191: http://bugs.mysql.com/9191)
  • A literal string in a GROUP BY clause could be interpreted as a column name. (Bug#14019: http://bugs.mysql.com/14019)
  • WITH ROLLUP could group unequal values. (Bug#20825: http://bugs.mysql.com/20825)
  • LIKE searches failed for indexed utf8 character columns. (Bug#20471: http://bugs.mysql.com/20471)
  • The optimizer sometimes mishandled R-tree indexes for GEOMETRY data types, resulting in a server crash. (Bug#21888: http://bugs.mysql.com/21888)
  • Entries in the slow query log could have an incorrect Rows_examined value. (Bug#12240: http://bugs.mysql.com/12240)
  • Insufficient memory (myisam_sort_buffer_size) could cause a server crash for several operations on MyISAM tables: repair table, create index by sort, repair by sort, parallel repair, bulk insert. (Bug#23175: http://bugs.mysql.com/23175)
  • REPAIR TABLE ... USE_FRM could cause a server crash or hang when used for a MyISAM table in a database other than the default database. (Bug#22562: http://bugs.mysql.com/22562)
  • OPTIMIZE TABLE with myisam_repair_threads > 1 could result in MyISAM table corruption. (Bug#8283: http://bugs.mysql.com/8283)
  • The result for CAST() when casting a value to UNSIGNED was limited to the maximum signed BIGINT value (9223372036854775808), not the maximum unsigned value (18446744073709551615). (Bug#8663: http://bugs.mysql.com/8663)
  • For multiple-table UPDATE statements, storage engines were not notified of duplicate-key errors. (Bug#21381: http://bugs.mysql.com/21381)
  • Successive invocations of a COUNT(*) query containing a join on two MyISAM tables and a WHERE clause of the form WHERE (table1.column1 = table2.column2) OR table2.column2 IS NULL yielded different results. (Bug#21019: http://bugs.mysql.com/21019)
  • Using ALTER TABLE to add an ENUM column with an enumeration value containing 0xFF caused the name of the first table column to be lost. (Bug#20922: http://bugs.mysql.com/20922)
  • PROCEDURE ANALYSE() returned incorrect values of M FLOAT(M, D) and DOUBLE(M, D). (Bug#20305: http://bugs.mysql.com/20305)
  • A query that used GROUP BY and an ALL or ANY quantified subquery in a HAVING clause could trigger an assertion failure. (Bug#21853: http://bugs.mysql.com/21853)
  • For an ENUM column that used the ucs2 character set, using ALTER TABLE to modify the column definition caused the default value to be lost. (Bug#20108: http://bugs.mysql.com/20108)
  • Creating a TEMPORARY table with the same name as an existing table that was locked by another client could result in a lock conflict for DROP TEMPORARY TABLE because the server unnecessarily tried to acquire a name lock. (Bug#21096: http://bugs.mysql.com/21096)
  • Incorporated some portability fixes into the definition of __attribute__ in my_global.h. (Bug#2717: http://bugs.mysql.com/2717)
  • In the package of pre-built time zone tables that is available for download at http://dev.mysql.com/downloads/timezones.html, the tables now explicitly use the utf8 character set so that they work the same way regardless of the system character set value. (Bug#21208: http://bugs.mysql.com/21208)
  • The build process incorrectly tried to overwrite sql/lex_hash.h. This caused the build to fail when using a shadow link tree pointing to original sources that were owned by another account. (Bug#18888: http://bugs.mysql.com/18888)
  • Execution of a prepared statement that uses an IN subquery with aggregate functions in the HAVING clause could cause a server crash. (Bug#22085: http://bugs.mysql.com/22085)
  • Selecting from a MERGE table could result in a server crash if the underlying tables had fewer indexes than the MERGE table itself. (Bug#21617: http://bugs.mysql.com/21617, Bug#22937: http://bugs.mysql.com/22937)
  • SUBSTR() results sometimes were stored improperly into a temporary table when multi-byte character sets were used. (Bug#20204: http://bugs.mysql.com/20204)
  • Parallel builds occasionally failed on Solaris. (Bug#16282: http://bugs.mysql.com/16282)
  • The source distribution failed to compile when configured with the --without-geometry option. (Bug#12991: http://bugs.mysql.com/12991)
  • The server returns a more informative error message when it attempts to open a MERGE table that has been defined to use non-MyISAM tables. (Bug#10974: http://bugs.mysql.com/10974)
  • On Mac OS X, zero-byte read() or write() calls to an SMB-mounted filesystem could return a non-standard return value, leading to data corruption. Now such calls are avoided. (Bug#12620: http://bugs.mysql.com/12620)
  • For INSERT ... ON DUPLICATE KEY UPDATE, use of VALUES(col_name) within the UPDATE clause sometimes was handled incorrectly. (Bug#21555: http://bugs.mysql.com/21555)
  • Table aliases in multiple-table DELETE statements sometimes were not resolved. (Bug#21392: http://bugs.mysql.com/21392)
  • EXPORT_SET() did not accept arguments with coercible character sets. (Bug#21531: http://bugs.mysql.com/21531)
  • The --collation-server server option was being ignored. With the fix for this problem, if you choose a non-default character set with --character-set-server, you should also use --collation-server to specify the collation. (Bug#15276: http://bugs.mysql.com/15276)
  • A subquery that uses an index for both the WHERE and ORDER BY clauses produced an empty result. (Bug#21180: http://bugs.mysql.com/21180)
  • Queries containing a subquery that used aggregate functions could return incorrect results. (Bug#16792: http://bugs.mysql.com/16792)
  • The MD5(), SHA1(), and ENCRYPT() functions should return a binary string, but the result sometimes was converted to the character set of the argument. MAKE_SET() and EXPORT_SET() now use the correct character set for their default separators, resulting in consistent result strings which can be coerced according to normal character set rules. (Bug#20536: http://bugs.mysql.com/20536)
  • Use of myisampack or myisamchk on a compressed MyISAM table with FULLTEXT indexing resulted in table corruption. (Bug#19702: http://bugs.mysql.com/19702)
  • The optimizer could produce an incorrect result after AND with collations such as latin1_german2_ci, utf8_czech_ci, and utf8_lithianian_ci. (Bug#9509: http://bugs.mysql.com/9509)
  • character_set_results can be NULL to signify "no conversion," but some code did not check for NULL, resulting in a server crash. (Bug#21913: http://bugs.mysql.com/21913)
  • The myisam_stats_method variable was mishandled when set from an option file or on the command line. (Bug#21054: http://bugs.mysql.com/21054)
  • libmysqld produced some warnings to stderr which could not be silenced. These warnings now are suppressed. (Bug#13717: http://bugs.mysql.com/13717)
  • If a column definition contained a character set declaration, but a DEFAULT value began with an introducer, the introducer character set was used as the column character set. (Bug#20695: http://bugs.mysql.com/20695)
  • Some Linux-x86_64-icc packages (of previous releases) mistakenly contained 32-bit binaries. Only ICC builds are affected, not gcc builds. Solaris and FreeBSD x86_64 builds are not affected. (Bug#22238: http://bugs.mysql.com/22238)
  • For TIME_FORMAT(), the %H and %k format specifiers can return values larger than two digits (if the hour is greater than 99), but for some query results that contained three-character hours, column values were truncated. (Bug#19844: http://bugs.mysql.com/19844)
  • For table-format output, mysql did not always calculate columns widths correctly for columns containing multi-byte characters in the column name or contents. (Bug#17939: http://bugs.mysql.com/17939)
  • Views could not be updated within a stored function or trigger. (Bug#17591: http://bugs.mysql.com/17591)
  • Usernames have a maximum length of 16 characters (even if they contain multi-byte characters), but were being truncated to 16 bytes. (Bug#20393: http://bugs.mysql.com/20393)
  • Database and table names have a maximum length of 64 characters (even if they contain multi-byte characters), but were being truncated to 64 bytes. (Bug#21432: http://bugs.mysql.com/21432)
  • When using tables created under MySQL 4.1 with a 5.0 server, if the tables contained VARCHAR columns, for some queries the metadata sent to the client could have an empty column name. (Bug#14897: http://bugs.mysql.com/14897)
  • On 64-bit systems, use of the cp1250 character set with a primary key column in a LIKE clause caused a server crash for patterns having letters in the range 128..255. (Bug#19741: http://bugs.mysql.com/19741)
  • A subquery in the WHERE clause of the outer query and using IN and GROUP BY returned an incorrect result. (Bug#16255: http://bugs.mysql.com/16255)
  • COUNT(*) queries with ORDER BY and LIMIT could return the wrong result. (Bug#21787: http://bugs.mysql.com/21787) Note: This problem was introduced by the fix for Bug#9676: http://bugs.mysql.com/9676, which limited the rows stored in a temporary table to the LIMIT clause. This optimization is not applicable to non-group queries with aggregate functions. The current fix disables the optimization in such cases.
  • Running SHOW MASTER LOGS at the same time as binary log files were being switched would cause mysqld to hang. (Bug#21965: http://bugs.mysql.com/21965)
  • Adding ORDER BY to a SELECT DISTINCT(expr) query could produce incorrect results. (Bug#21456: http://bugs.mysql.com/21456)
  • For InnoDB tables, the server could crash when executing NOT IN () subqueries. (Bug#21077: http://bugs.mysql.com/21077)
  • mysqld --flush failed to flush MyISAM table changes to disk following an UPDATE statement for which no updated column had an index. (Bug#20060: http://bugs.mysql.com/20060)
  • The --with-collation option was not honored for client connections. (Bug#7192: http://bugs.mysql.com/7192)
  • NDB Cluster: Attempting to create an NDB table on a MySQL with an existing non-Cluster table with the same name in the same database could result in data loss or corruption. MySQL now issues a warning when a SHOW TABLES or other statement causing table discovery finds such a table. (Bug#21378: http://bugs.mysql.com/21378)
  • NDB Cluster (NDB API): Attempting to read a nonexistent tuple using Commit mode for NdbTransaction::execute() caused node failures. (Bug#22672: http://bugs.mysql.com/22672)
  • NDB Cluster: Restoring a cluster failed if there were any tables with 128 or more columns. (Bug#23502: http://bugs.mysql.com/23502)
  • NDB Cluster: INSERT ... ON DUPLICATE KEY UPDATE on an NDB table could lead to deadlocks and memory leaks. (Bug#23200: http://bugs.mysql.com/23200)
  • NDB Cluster: If a node restart could not be performed from the REDO log, no node takeover took place. This could cause partitions to be left empty during a system restart. (Bug#22893: http://bugs.mysql.com/22893)
  • NDB Cluster: Multiple node restarts in rapid succession could cause a system restart to fail (Bug#22892: http://bugs.mysql.com/22892), or induce a race condition (Bug#23210: http://bugs.mysql.com/23210).
  • NDB Cluster: The node recovery algorithm was missing a version check for tables in the ALTER_TABLE_COMMITTED state (as opposed to the TABLE_ADD_COMMITTED state, which has the version check). This could cause inconsistent schemas across nodes following node recovery. (Bug#21756: http://bugs.mysql.com/21756)
  • NDB Cluster: The output for the --help option used with NDB executable programs (ndbd, ndb_mgm, ndb_restore, ndb_config, and so on) referred to the Ndb.cfg file, instead of my.cnf. (Bug#21585: http://bugs.mysql.com/21585)
  • NDB Cluster: The ndb_mgm management client did not set the exit status on errors, always returning 0 instead. (Bug#21530: http://bugs.mysql.com/21530)
  • NDB Cluster: Cluster logs were not rotated following the first rotation cycle. (Bug#21345: http://bugs.mysql.com/21345)
  • NDB Cluster: When inserting a row into an NDB table with a duplicate value for a non-primary unique key, the error issued would reference the wrong key. (Bug#21072: http://bugs.mysql.com/21072)
  • NDB Cluster: Under some circumstances, local checkpointing would hang, keeping any unstarted nodes from being started. (Bug#20895: http://bugs.mysql.com/20895)
  • NDB Cluster: In some cases where SELECT COUNT(*) from an NDB table should have yielded an error, MAX_INT was returned instead. (Bug#19914: http://bugs.mysql.com/19914)
  • NDB Cluster: ndb_restore did not always make clear that it had recovered successfully from temporary errors while restoring a cluster backup. (Bug#19651: http://bugs.mysql.com/19651)
  • NDB Cluster: A problem with takeover during a system restart caused ordered indexes to be rebuilt incorrectly. (Bug#15303: http://bugs.mysql.com/15303)
  • NDB Cluster: The ndb_mgm program was included in both the MySQL-ndb-tools and MySQL-ndb-management RPM packages, resulting in a conflict if both were installed. Now ndb_mgm is included only in MySQL-ndb-tools. (Bug#21058: http://bugs.mysql.com/21058)
  • NDB Cluster: ndb_size.pl and ndb_error_reporter were missing from RPM packages. (Bug#20426: http://bugs.mysql.com/20426)
  • NDB Cluster: Setting TransactionDeadlockDetectionTimeout to a value greater than 12000 would cause scans to deadlock, time out, fail to release scan records, until the cluster ran out of scan records and stopped processing. (Bug#21800: http://bugs.mysql.com/21800)
  • NDB Cluster: The server provided a non-descriptive error message when encountering a fatally corrupted REDO log. (Bug#21615: http://bugs.mysql.com/21615)
  • NDB Cluster: A partial rollback could lead to node restart failures. (Bug#21536: http://bugs.mysql.com/21536)
  • NDB Cluster: The failure of a unique index read due to an invalid schema version could be handled incorrectly in some cases, leading to unpredictable results. (Bug#21384: http://bugs.mysql.com/21384)
  • NDB Cluster: In a cluster with more than 2 replicas, a manual restart of one of the data nodes could fail and cause the other nodes in its nodegroup to shut down. (Bug#21213: http://bugs.mysql.com/21213)
  • NDB Cluster: When the redo buffer ran out of space, a Pointer too large error was raised and the cluster could become unusable until restarted with --initial. (Bug#20892: http://bugs.mysql.com/20892)
  • NDB Cluster: In some situations with a high disk-load, writing of the redo log could hang, causing a crash with the error message GCP STOP detected. (Bug#20904: http://bugs.mysql.com/20904)
  • NDB Cluster: ndb_size.pl and ndb_error_reporter were missing from RPM packages. (Bug#20426: http://bugs.mysql.com/20426)
  • NDB Cluster: The server failed with a non-descriptive error message when out of data memory. (Bug#18475: http://bugs.mysql.com/18475)
  • NDB Cluster: SELECT ... FOR UPDATE failed to lock the selected rows. (Bug#18184: http://bugs.mysql.com/18184)
  • NDB Cluster: Some queries involving joins on very large NDB tables could crash the MySQL server. (Bug#21059: http://bugs.mysql.com/21059)
  • Character set collation was ignored in GROUP BY clauses. (Bug#20709: http://bugs.mysql.com/20709)
  • A query using WHERE column = constant OR column IS NULL did not return consistent results on successive invocations. The column in each part of the WHERE clause could be either the same column, or two different columns, for the effect to be observed. (Bug#21019: http://bugs.mysql.com/21019)
  • A query using WHERE NOT (column < ANY (subquery)) yielded a different result from the same query using the same column and subquery with WHERE (column > ANY (subquery)). (Bug#20975: http://bugs.mysql.com/20975)
  • Using the extended syntax for TRIM() --- that is, TRIM(... FROM ...) --- caused erroneous output from EXPLAIN EXTENDED statements. (Bug#17526: http://bugs.mysql.com/17526)
  • DELETE with WHERE condition on a BTREE-indexed column for a MEMORY table deleted only the first matched row. (Bug#9719: http://bugs.mysql.com/9719)
  • For cross-database multiple-table UPDATE statements, a user with all privileges for the default database could update tables in another database for which the user did not have UPDATE privileges. (Bug#7391: http://bugs.mysql.com/7391)
  • mysql_install_db incorrectly had a blank first line. (Bug#20721: http://bugs.mysql.com/20721)
  • Under heavy load (executing more than 1024 simultaneous complex queries), a problem in the code that handles internal temporary tables could lead to writing beyond allocated space and memory corruption. (Bug#21206: http://bugs.mysql.com/21206)
  • Multiple invocations of the REVERSE() function could return different results. (Bug#18243: http://bugs.mysql.com/18243)
  • Conversion of TIMESTAMP values between UTC and the local time zone resulted in some values having the year 2069 rather than 1969. (Bug#16327: http://bugs.mysql.com/16327)
  • Under certain circumstances, AVG(key_val) returned a value but MAX(key_val) returned an empty set due to incorrect application of MIN()/MAX() optimization. (Bug#20954: http://bugs.mysql.com/20954)
  • Using aggregate functions in subqueries yielded incorrect results under certain circumstances due to incorrect application of MIN()/MAX() optimization. (Bug#20792: http://bugs.mysql.com/20792)
  • Using > ALL with subqueries that return no rows yielded incorrect results under certain circumstances due to incorrect application of MIN()/MAX() optimization. (Bug#18503: http://bugs.mysql.com/18503)
  • Using ANY with "non-table" subqueries such as SELECT 1 yielded incorrect results under certain circumstances due to incorrect application of MIN()/MAX() optimization. (Bug#16302: http://bugs.mysql.com/16302)
  • The use of WHERE col_name IS NULL in SELECT statements reset the value of LAST_INSERT_ID() to zero. (Bug#14553: http://bugs.mysql.com/14553)
  • Use of the join cache in favor of an index for ORDER BY operations could cause incorrect result sorting. (Bug#17212: http://bugs.mysql.com/17212)
  • libmysqld returned TEXT columns to the client as number of bytes, not number of characters (which can be different for multi-byte character sets). (Bug#19983: http://bugs.mysql.com/19983)

Mooi dat de bug die als eerste in de lijst genoemd word (index corruption bij deleting van veel records) gefixt is. Dit was een vaak voorkomend probleem bij phpbb fora, waardoor je een table er zelf opnieuw in moest zetten.
bij iedere update van MySQL denk ik:

WOW, zitten toch weer dikke bugfixes in :(
dat is toch positief? :P bij oracle laten ze ze rustig zitten ;)
Wat een ongeloooflijk lange bugfix lijst!
ik hoop dat 4.1.23 snel uitkomt want er ligt nog een hoop werk.

Op dit item kan niet meer gereageerd worden.
