Changes 5.5.0:

Functionality Added or Changed

The version of the tcmalloc library included in MySQL distributions was very old. It has been removed and is no longer included with MySQL.


Bugs Fixed

INSERT with ON DUPLICATE KEY UPDATE and REPLACE on a table with a foreign key constraint defined failed with an incorrect “duplicate entry” error rather than a foreign key constraint violation error.

Setting sort_buffer_size to a very large value could cause some operations to fail with an out-of-memory error.

Several potential buffer overflow issues were corrected.

If the CA certificate as given to the --ssl-ca option had an invalid path, yaSSL returned an error message different from OpenSSL. Now both return SSL connection error: SSL_CTX_set_default_verify_paths failed.

Some string functions returned one or a combination of their parameters as their result. If one of the parameters had a non-ASCII character set, the result string had the same character set, resulting in incorrect behavior when an ASCII string was expected.

A null pointer dereference of a parser structure could occur during stored procedure name validation.

mysqld_multi displayed misleading error messages when it was unable to execute my_print_defaults.
