D.4.6. Alterações na distribuição 3.23.54 (05 Dec 2002)

  • Fixed a bug, that allowed to crash mysqld with a specially crafted packet.

  • Fixed a rare crash (double free'd pointer) when altering a temporary table.

  • Fixed buffer overrun in libmysqlclient library that allowed malicious MySQL server to crash the client application.

  • Fixed security-related bug in mysql_change_user() handling. All users are strongly recommended to upgrade to the version 3.23.54.

  • Fixed bug that prevented --chroot command-line option of mysqld from working.

  • Fixed bug that made OPTIMIZE TABLE to corrupt the table under some rare circumstances.

  • Fixed mysqlcheck so it can deal with table names containing dashes.

  • Fixed shutdown problem on Mac OS X.

  • Fixed bug with comparing an indexed NULL field with <=> NULL.

  • Fixed bug that caused IGNORE INDEX and USE INDEX sometimes to be ignored.

  • Fixed rare core dump problem in complicated GROUP BY queries that didn't return any result.

  • Fixed a bug where MATCH ... AGAINST () >=0 was treated as if it was >.

  • Fixed core dump in SHOW PROCESSLIST when running with an active slave (unlikely timing bug).

  • Make it possible to use multiple MySQL servers on Windows (code backported from 4.0.2).

  • One can create TEMPORARY MERGE tables now.

  • Fixed that --core-file works on Linux (at least on kernel 2.4.18).

  • Fixed a problem with BDB and ALTER TABLE.

  • Fixed reference to freed memory when doing complicated GROUP BY ... ORDER BY queries. Symptom was that mysqld died in function send_fields.

  • Allocate heap rows in smaller blocks to get better memory usage.

  • Fixed memory allocation bug when storing BLOB values in internal temporary tables used for some (unlikely) GROUP BY queries.

  • Fixed a bug in key optimising handling where the expression WHERE column_name = key_column_name was calculated as true for NULL values.

  • Fixed core dump bug when doing LEFT JOIN ... WHERE key_column=NULL.

  • Fixed MyISAM crash when using dynamic-row tables with huge numbers of packed fields.

  • Updated source tree to be built using automake 1.5 and libtool 1.4.
