Dear MySQL users, MySQL Server 5.6.37, a new version of the popular Open Source Database Management System, has been released. MySQL 5.6.37 is recommended for use on production systems. For an overview of what's new in MySQL 5.6, please see http://dev.mysql.com/doc/refman/5.6/en/mysql-nutshell.html Starting with 5.6.11, Microsoft Windows packages for MySQL 5.6 are available both as a "full" installer and as a "web" installer. The full installer is significantly larger and comes bundled with the latest software releases available. This bundle makes it easy to download and configure a full server and development suite. The web installer doesn't come bundled with any actual products and instead relies on download-on-demand to fetch only the products you choose to install. This makes the initial download much smaller but increases install time as the individual products will need to be downloaded. For information on installing MySQL 5.6.37 on new servers or upgrading to MySQL 5.6.37 from previous MySQL releases, please see http://dev.mysql.com/doc/refman/5.6/en/installing.html MySQL Server is available in source and binary form for a number of platforms from our download pages at http://dev.mysql.com/downloads/ Not all mirror sites may be up to date at this point in time, so if you can't find this version on some mirror, please try again later or choose another download site. We welcome and appreciate your feedback, bug reports, bug fixes, patches, etc: https://wikis.oracle.com/display/mysql/Contributing The following link lists the changes in the MySQL 5.6 since the release of MySQL 5.6.36. It may also be viewed online at http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-37.html Enjoy! Changes in MySQL 5.6.37 (2017-07-17, General Availability) * Packaging Notes * Security Notes * Platform-Specific Notes * Functionality Added or Changed * Bugs Fixed Packaging Notes * mysqladmin was added to Docker/Minimal packages because it is needed by InnoDB Cluster. (Bug #25998285) Security Notes * Security Fix: The linked OpenSSL library for the MySQL Commercial Server has been updated to version 1.0.2l. Issues fixed in the new OpenSSL version are described at http://www.openssl.org/news/vulnerabilities.html. This change does not affect the Oracle-produced MySQL Community build of MySQL Server, which uses the yaSSL library instead. (Bug #26160962) Platform-Specific Notes * Linux: The generic Linux build for MySQL 5.6 is now built on Oracle Linux 6 using glibc 2.12. Systems that use the build need to have glibc 2.12 or later installed on them. (Bug #26005558) Functionality Added or Changed * For Windows, MSI installer packages now include a check for the required Visual Studio redistributable package, and produce a message asking the user to install it if it is missing. (Bug #25658832) * The mysql client now supports a --binary-as-hex option that causes display of binary data using hexadecimal notation (0xvalue). Thanks to Daniël van Eeden for the patch. (Bug #25340722, Bug #84391) * mysqlaccess now looks for its configuration file only in the SYSCONFDIR directory and /etc. (Bug #25043674) Bugs Fixed * InnoDB: The server allocated memory unnecessarily for an operation that rebuilt the table. (Bug #25573565, Bug #85043) * InnoDB: When using an index merge optimizer switch, a SELECT COUNT(*) operation sometimes returned 0. Partitioning code incorrectly performed a memcpy instead of a column copy of columns read by the index, causing the wrong records to be copied. (Bug #25332330, Bug #81031) * Replication: A USE statement that followed a SET GTID_NEXT statement sometimes had no effect. (Bug #26128931) * Replication: If the binary log on a master server was rotated and a full disk condition occurred on the partition where the binary log file was being stored, the server could stop unexpectedly. The fix adds a check for the existence of the binary log when the dump thread switches to next binary log file. If the binary log is disabled, all binary logs up to the current active log are transmitted to slave and an error is returned to the receiver thread. (Bug #25076007) * Replication: If a relay log index file named relay log files that did not exist, RESET SLAVE ALL sometimes did not fully clean up properly. (Bug #24901077) * Replication: mysqlbinlog, if invoked with the --raw option, does not flush the output file until the process terminates. But if also invoked with the --stop-never option, the process never terminates, thus nothing is ever written to the output file. Now the output is flushed after each event. (Bug #24609402) * Replication: Multi-threaded slaves could not be configured with small queue sizes using slave_pending_jobs_size_max if they ever needed to process transactions larger than that size. Any packet larger than slave_pending_jobs_size_max was rejected with the error ER_MTS_EVENT_BIGGER_PENDING_JOBS_SIZE_MAX, even if the packet was smaller than the limit set by slave_max_allowed_packet. With this fix, slave_pending_jobs_size_max becomes a soft limit rather than a hard limit. If the size of a packet exceeds slave_pending_jobs_size_max but is less than slave_max_allowed_packet, the transaction is held until all the slave workers have empty queues, and then processed. All subsequent transactions are held until the large transaction has been completed. The queue size for slave workers can therefore be limited while still allowing occasional larger transactions. (Bug #21280753, Bug #77406) * mysqldump could write database names in USE statements incorrectly. (Bug #25998635) * If the mysql_stmt_close() C API function was called, it freed memory that later could be accessed if mysql_stmt_error(), mysql_stmt_errno(), or mysql_stmt_sqlstate() was called. To obtain error information after a call to mysql_stmt_close(), call mysql_error(), mysql_errno(), or mysql_sqlstate() instead. (Bug #25988681) * Queries could be cached incorrectly, leading to incorrect query results, under these circumstances: InnoDB table; rows are being inserted but have not yet been committed; a query uses the table as a base table in a derived table; the optimizer chooses to materialize the derived table. (Bug #25943038, Bug #86047) * Man pages for a few utilities were missing from Debian/Ubuntu packages. (Bug #25811814) * The field-t unit test failed to run with AddressSanitizer enabled. Thanks to Laurynas Biveinis for the patch. (Bug #25803823, Bug #85678) * Debian client packages were missing information about conflicts with native packages. (Bug #25799475) * The Perl path in #! lines at the beginning of Perl scripts has been adjusted to /usr/local/bin/perl for FreeBSD 11. (Bug #25719975) * The server exited abnormally attempting to access invalid memory. (Bug #25501659) * A race condition could occur for CREATE TABLE statements with DATA DIRECTORY or INDEX DIRECTORY clauses. (Bug #25451091) * MySQL compilation in different directories produced different builds to leakage of absolute paths into debug information and __FILE__. (Bug #25436469, Bug #84608) * mysqld_failed to start the server if the --datadir option was specified with a relative path name. (Bug #25364806) * With read_only enabled, creation of non-TEMPORARY tables by non-SUPER users was permitted under certain conditions. (Bug #25250768) * Certain stored functions, if used in a query WHERE clause, could be handled using Index Condition Pushdown (which should not happen), resulting in a server exit. (Bug #25196653, Bug #25174454) * On x86 machines, the uint3korr() macro read 4 bytes of data instead of the intended 3 bytes. (Bug #24807826, Bug #83264) * An assertion was raised during a fetch operation by the memcached plugin. (Bug #24605783) * Queries that contained UNION in a subquery and GROUP BY could return incorrect results. (Bug #24595639) * LOAD XML INFILE performance became noticeably slower when the XML file being read contained a great many spaces, such as those introduced by indenting or pretty-printing. Now all leading whitespace is trimmed from each such value before reading it into memory. (Bug #16212207) On behalf of the Oracle MySQL Release Engineering Team, Nawaz Nazeer Ahamed
