Changes in MySQL 5.1.73 (December 03, 2013)

Packaging Notes

  * Previously, MySQL Server distributions included the MySQL
    Reference Manual in Info format (the Docs/ file).
    Because the license for the manual restricts redistribution,
    its inclusion in Community packages caused problems for
    downstream redistributors, such as those who create Linux
    distributions. Community distributions of MySQL Server no
    longer include the file, to make the repackaging
    and redistribution process easier (for example, the source
    tarball and its checksum can be used directly). This change
    applies to all source and binary Community packaging formats.
    Commercial (Enterprise) distributions are unchanged.
    For Those who wish to continue using the MySQL Reference
    Manual in Info format, we have made it available at

Bugs Fixed

  * InnoDB: In debug builds, test case failures would occur due to
    ibuf_contract_ext performing merges and dict_stats_update
    returning evicted pages back into the buffer pool while
    ibuf_change_buffering_debug is enabled. (Bug #17446090)

  * InnoDB: InnoDB would fail to return an error when attempting
    to run a query after discarding the tablespace. (Bug

  * InnoDB: When the change buffer is enabled, InnoDB would fail
    to write a transaction log record when merging a record from
    the insert buffer to a secondary index page if the insert was
    performed as an "update-in-place". (Bug #16752251, Bug #69122)

  * Partitioning: The storage engine was set incorrectly during a
    rebuild of a partition; the table storage engine was ignored
    and the default storage engine used instead. Thus, in MySQL
    5.1, it was possible for REBUILD PARTITION to change the
    partition storage engine from InnoDB to MyISAM, and for the
    reverse (rebuilding partitions of MyISAM tables causing the
    partitions to use InnoDB) to occurin MySQL 5.5 and later. Now,
    when rebuilding partitions, the storage engine actually used
    by the table is checked and used by the handler for the
    rebuild operation, so that the partition storage engine is not
    inadvertently changed. (Bug #17559867)

  * Replication: When an error encountered by the dump thread
    while reading events from the active binary log file was a
    temporary error, so that the dump thread tried to read the
    event, it was possible for the dump thread to seek the wrong
    position, which could cause one or more events to be resent.
    To prevent this, the thread's position is obtained after each
    correct read of an event.
    In addition, with this fix, only binary logs that are not
    closed normally are marked as possibly being corrupted.
    Finally, two warnings are added; these are now returned when a
    dump thread encounters a temporary error. (Bug #17402313)

  * Replication: The value of LAST_INSERT_ID() was not correctly
    replicated when filtering rules were used on the slave. (Bug
    #17234370, Bug #69861)

  * Enabling Index Merge optimizer switches and setting a small
    sort_buffer_size value could lead to a server exit. (Bug

  * The mysql_options() C API function could leak memory if called
    more than once with the MYSQL_SET_CLIENT_IP option. (Bug

  * An error array in the SSL code was missing a comma, leading to
    implicit concatenation of adjacent messages and a resulting
    off-by-one error in the relationship between error numbers and
    messages. (Bug #17294150)

  * The filesort implementation sometimes failed to allocate
    enough buffer space, leading to a server exit. (Bug #17326567)

  * Very long database names in queries could cause the server to
    exit. (Bug #15912213, Bug #16900358)

  * The my_b_vprintf() function could produce incorrect results
    for long integers on 64-bit systems. (Bug #67386, Bug

  * Host names in grant tables are stored in lowercase, but
    mysql_install_db could fail to observe this convention,
    leading to accounts that could not be dropped with DROP USER.
    (Bug #62255, Bug #12917164, Bug #62254, Bug #12917151)
