Changes in MySQL 5.5.59 (2018-01-15, General availability)
* Configuration Notes
* Test Suite Notes
* Bugs Fixed
Configuration Notes
* For RHEL, SLES, and Fedora RPMs, the default plugin
directory for debug builds has been changed from
/usr/lib64/mysql/plugin to /usr/lib64/mysql/plugin/debug. (Bug
#27072155, Bug #88363)
Test Suite Notes
* Documentation for the MySQL Test Suite is now maintained
in the MySQL source tree using Doxygen (see
http://dev.mysql.com/doc/dev/mysql-server/latest/PAGE_MYSQL_TEST_RUN.html).
The related Unix man pages that previously were
produced from the old test suite manual are no longer updated and
have gone out of date. Consequently, they are no longer included
in MySQL distributions. (Bug #27021754)
Bugs Fixed
* InnoDB: While innodb_undo_log_truncate was enabled,
warnings that should only appear in a debug version of MySQL were
printed to the error log when the length of the history list
exceeded 2000000. (Bug #24296076, Bug #82213)
* Packaging: Initialization of the MySQL Server Docker
container failed with the message "hostname: command not found"
when the server was being initialized. That was due to a missing
library in the Docker image. (Bug #26747305)
* Partitioning: Queries involving NULL were not always
handled correctly on tables that were partitioned by LIST. (Bug
#76418, Bug #20748521) References: See also: Bug #86255, Bug
#26034430.
* Microsoft Windows: On Windows, with the myisam_use_mmap
and flush system variables enabled, MyISAM did not always flush
table files properly. (Bug #26880757)
* VALUES() was not handled correctly in some cases. (Bug
#26881946) References: See also: Bug #19601973, Bug #17458914.
* Incorrect results or a server exit could result when
SHA2() was passed a user-defined variable in some character sets.
(Bug #26704451)
* Creating a table with excessive index information could
cause a server exit. (Bug #26529369)
* Setting the MYSQL_GROUP_SUFFIX environment variable had
no effect. (Bug #23072792)
* A circular dependency problem involving
sql/sql_builtin.cc was resolved. (Bug #16877045)
* A prepared statement containing an ORDER BY list that
referred to a parameter was not always handled correctly. (Bug
#87863, Bug #26867652)
