完全改进：
Changes in MySQL 5.1.71 (2013-08-01)
Functionality Added or Changed
comp_err now checks to make sure that new errors are not being added to MySQL 5.1 or 5.5 because the set of errors for these series is frozen. (Bug #16807394)
Bugs Fixed
InnoDB: During an insert buffer merge, InnoDB would invokelock_rec_restore_from_page_infimum()on a potentially invalid record pointer. (Bug #16806366)
InnoDB: Thepage_zip_validate()consistency check would fail after compressing a page, inpage_zip_compress(). This problem was caused bypage_zip_decompress(), which would fail to setheap_nocorrectly when a record contained no user data bytes. A record with no user data bytes occurs when, for example, a primary key is an empty string and all secondary index fields are NULL or an empty string. (Bug #16736929)
InnoDB: Thepthread_mutex,commit_threads_m, which was initialized but never used, has been removed from the code base. (Bug #60225, Bug #11829813)
Partitioning: When dropping a partitioned table, the table's.parfile was deleted first, before the table definition or data. This meant that, if the server failed during the drop operation, the table could be left in an inconsistent state in which it could neither be accessed nor dropped.
The fix for this problem makes the following changes:
Now, when dropping a partitioned table, the table's.parfile is not removed until all table data has been deleted.
When executing DROP TABLE of a partitioned table, in the event that its.parfile is determined to be missing, the table's.frmfile is now immediately deleted, in effect forcing the drop to complete.
(Bug #13548704, Bug #63884)
Shared-compatibility conflict errors occurred for RPM install operations, even if no shared-compatibility RPMs were already installed. (Bug #16678122)
A user variable referenced during execution of a prepared statement is set to memory that is freed at the end of execution. A second execution of the statement could result in Valgrind warnings when accessing this memory. (Bug #16119355)
Misoptimization of left expressions in prepared statements could cause a server exit. (Bug #16095534)
Subsequent toPrepared statement needs to be re-preparederrors, inserts into DECIMAL columns caused a server exit. (Bug #12608543)
Assigning the result of a subquery to a user variable raised an assertion when the outer query includedDISTINCTandGROUP BY. (Bug #57196, Bug #11764371)
