======================================================================D.1.1. Changes in MySQL 5.1.60 (16 November, 2011)

Functionality Added or Changed

* Upgrading from an Advanced GPL RPM package to an Advanced RPM
package did not work. Now on Linux it is possible to use rpm
-U to replace any installed MySQL product by any other of the
same release family. It is not necessary to remove the old
produce with rpm -e first. (Bug #11886309)

* MEMORY table creation time is now available in the CREATE_TIME
column of the INFORMATION_SCHEMA.TABLES table and the
Create_time column of SHOW TABLE STATUS output. (Bug #51655,
Bug #11759349)

Bugs Fixed

* InnoDB Storage Engine: This fix improves the performance of
instrumentation code for InnoDB buffer pool operations. (Bug
#12950803, Bug #62294)

* InnoDB Storage Engine: Data from BLOB columns could be lost if
the server crashed at a precise moment when other columns were
being updated in an InnoDB table. (Bug #12704861)

* InnoDB Storage Engine: Lookups using secondary indexes could
give incorrect matches under a specific set of conditions. The
conditions involve an index defined on a column prefix, for a
BLOB or other long column stored outside the index page, with
a table using the Barracuda file format. (Bug #12601439)

* InnoDB Storage Engine: This fix corrects cases where the MySQL
server could hang or abort with a long semaphore wait message.
(This is a different issue than when these symptoms occurred
during a CHECK TABLE statement.) (Bug #11766591, Bug #59733)

* Replication: Issuing the following statements, in the order
shown, could cause a deadlock between the user thread and I/O
thread:
START SLAVE;
STOP SLAVE SQL_THREAD;
START SLAVE;
(Bug #11878104)
See also Bug #44312, Bug #11752963, Bug #38715, Bug #38716.

* Internal conversion of zero to binary and back could yield a
result with incorrect precision. (Bug #12911710)

* Valgrind warnings generated by filesort operations were fixed.
(Bug #12856915)

* Several improvements were made to the libedit library bundled
with MySQL distributions, and that is available for all
platforms that MySQL supports except Windows.

+ Navigation keys did not work for UTF-8 input.

+ Word navigation and delete operations did not work for
UTF-8 input with Cyrillic characters.

+ Nonlatin characters were corrupted in overwrite mode for
UTF-8 input.

+ Long queries caused the statement history file to become
corrupted.

+ The Alt key caused history operations to fail.
(Bug #12605400, Bug #12613725, Bug #12618092, Bug #12624155,
Bug #12617651, Bug #12605388)

* The help message for mysql_install_db did not indicate that it
supports the --defaults-file, --defaults-extra-file and
--no-defaults options. (Bug #58898, Bug #11765888)

* An assertion designed to detect zero-length sort keys also was
raised when the entire key set fit in memory. (Bug #58200, Bug
#11765254)

* myisampack could create corrupt FULLTEXT indexes when
compressing tables. (Bug #53646, Bug #11761180)

* OPTIMIZE TABLE could corrupt MyISAM tables if myisam_use_mmap
was enabled. (Bug #49030, Bug #11757032)

* If MySQL was configured with --without-plugin-innobase and
--with-plugin-innodb_plugin, to suppress building the built-in
InnoDB storage engine and build the InnoDB Plugin instead, the
innochecksum utility was not built. (Bug #47337, Bug
#11755544)

* A linking problem prevented the FEDERATED storage engine
plugin from loading. (Bug #40942, Bug #11750417)

* On Fedora, certain accesses to /var/lib/mysql/HOSTNAME.err
were blocked by SELinux policy, which made the server fail at
startup with the message: Manager of pid-file quit without
updating file (Bug #37165, Bug #12927740)

* For FEDERATED tables, loss of connection to the remote table
during some insert operations could cause a server crash. (Bug
#34660, Bug #11747970)
