Subject:MySQL Community Server 5.7.14 has been released
View as plain text  
Dear MySQL users,

MySQL Server 5.7.14, a new version of the popular Open Source
Database Management System, has been released. MySQL 5.7.14 is
recommended for use on production systems.

Since MySQL Server 5.7.13, we have introduced the concept of
Rapid Plugins. Out of the box, 5.7.14 follows the same stability promise
as our current release process, but it also allows for plugins with
additional functionality to be installed very easily. The first plugin
to be released with MySQL Server 5.7.14 following this concept is the
new X Plugin, which exposes a new communications protocol called the X
Protocol. The expanded capabilities of the X Protocol enable us to
provide the new X DevAPI in our MySQL Connectors and Client
applications, like the new MySQL Shell. The goal of the X DevAPI is to
support a new schema object type called document collections as well as
relational and combined document store/relational capabilities. Now
developers, designers and DBAs can deploy MySQL databases that implement
document store, relational, or hybrid document/relation models. For
documentation about how to get started using MySQL as a document store,
see http://dev.mysql.com/doc/refman/5.7/en/document-store.html.

For an overview of what's new in MySQL 5.7, please see

http://dev.mysql.com/doc/refman/5.7/en/mysql-nutshell.html

For information on installing MySQL 5.7.14 on new servers, please see
the MySQL installation documentation at

http://dev.mysql.com/doc/refman/5.7/en/installing.html

MySQL Server 5.7.14 is available in source and binary form for a number of
platforms from our download pages at

http://dev.mysql.com/downloads/mysql/

MySQL Server 5.7.14 is also available from our repository for Linux
platforms, go here for details:

http://dev.mysql.com/downloads/repo/

Windows packages are available via the Installer for Windows or .ZIP
(no-install) packages for more advanced needs. The point and click
configuration wizards and all MySQL products are available in the
unified Installer for Windows:

http://dev.mysql.com/downloads/installer/

5.7.14 also comes with a web installer as an alternative to the full
installer.

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.

We welcome and appreciate your feedback, bug reports, bug fixes,
patches, etc.:

The following section lists the changes in MySQL 5.7 since
the release of MySQL 5.7.13. It may also be viewed

Enjoy!

Changes in MySQL 5.7.14 (2016-07-29)

     sys Schema Notes

       * The sys schema now has a quote_identifier() function
         that, given a string argument, produces a quoted
         identifier suitable for inclusion in SQL statements. (Bug
         #22011361, Bug #78823)

       * Output from the sys schema diagnostics() procedure now
         includes the Tls_version column from the
         mysql.slave_master_info system table.

     Functionality Added or Changed

       * The %global compatver value for RPM packages for RHEL/OEL
         and Fedora releases was updated from 5.6.25 to 5.6.31.
         (Bug #23038018)
         References: See also: Bug #22980983.

       * Specifying an empty value for the --port option (for
         example, --port=, --port="") is now deprecated and
         results in a warning. An empty value will be an error in
         MySQL 8.0. (Bug #23023457, Bug #80903)

       * CMake support for compiling with Solaris Studio 12.5 was
         added. (Bug #81274, Bug #23212938)

       * The INFORMATION_SCHEMA INNODB_LOCKS and INNODB_LOCK_WAITS
         tables are now deprecated and will be removed in a future
         MySQL release.

     Bugs Fixed

       * Performance: A flaw in the allocation of memory for
         appending string values caused some operations to be
         performed slowly, including creation of tables having
         generated columns and inserts of large values into JSON
         columns. (Bug #80556, Bug #22843444)
         References: See also: Bug #22157531, Bug #22239803.

       * InnoDB: Full-text search auxiliary tables could be
         dropped by one session while being access by another.
         (Bug #23742339)

       * InnoDB: Selecting full-text index information schema
         tables for a deleted table caused a segmentation fault.
         (Bug #23479595)

       * InnoDB: A tablespace operation did not properly update
         the SYS_VIRTUAL system table. (Bug #23325659)

       * InnoDB: Rollback of a full-text index synchronization
         operation raised an assertion. The rollback operation
         attempted to acquire a mutex still held by the background
         synchronization thread. (Bug #23320569)

       * InnoDB: After compressing a table, an incorrect data
         length was passed to an internal tablespace encryption
         function, causing an assertion. (Bug #23279788)
         References: This issue is a regression of: Bug #22956469.

       * InnoDB: An r-tree page lock placed during a search
         operation prevented an undo operation within the same
         transaction from merging pages. (Bug #23241575)

       * InnoDB: A bulk load insert of a record with a compressed
         size greater than half of the compressed page size
         resulted in infinite B-tree page splitting when
         compressing the uncompressed page. (Bug #23120933)

       * InnoDB: A lock order violation related to InnoDB
         full-text search caused errors and raised an assertion.
         (Bug #23120005)
         References: This issue is a regression of: Bug #22996488.

       * InnoDB: In read-only mode, InnoDB attempted to set a
         corrupt bit in the SYS_INDEXES system table. In read-only
         mode, the corruption should only be marked in memory.
         (Bug #23077748)

       * InnoDB: InnoDB attempted to materialize non-key generated
         virtual columns that were not required for partitioning.
         (Bug #23037025)
         References: This issue is a regression of: Bug #21864838.

       * InnoDB: An insert operation on a table containing virtual
         and spatial indexes raised an assertion due to an invalid
         parent path encountered during page splitting. (Bug
         #23008863)

       * InnoDB: An ALTER TABLE operation on a table with an
         indexed virtual column raised an assertion. (Bug
         #22965271)

       * InnoDB: Adding or dropping a generated virtual column
         could raise an assertion due to a table handle held by an
         active memcached connection. (Bug #22922527)

       * InnoDB: A full-text query that involved a large number of
         records exceeded the result cache limit and caused a
         server exit. (Bug #22709692, Bug #80296)

       * InnoDB: InnoDB did not block the creation of a foreign
         key constraint with referential actions on the base
         column of a generated stored column. (Bug #22687023, Bug
         #80304)

       * InnoDB: The optimizer failed to mark the columns required
         for MATCH function evaluation when the secondary index
         used for the full-text query was not chosen by the
         optimizer. (Bug #22679209, Bug #80298)

       * InnoDB: In READ COMMITTED isolation level, InnoDB
         unnecessarily acquired the lock_sys mutex at COMMIT for a
         transaction block consisting of read-only SELECT
         statements.
         Thanks to Zhai Weixiang for the patch. (Bug #22617328,
         Bug #76728)

       * InnoDB: Setting innodb_monitor_enable to all did not
         enable all counters. (Bug #22576241, Bug #80083)

       * InnoDB: InnoDB now permits defining a foreign key
         constraint with a cascading referential action on the
         base column of an indexed virtual column, and defining
         cascading referential actions on non-virtual foreign key
         columns that are explicitly included in a virtual index.
         (Bug #22469130, Bug #79772)

       * InnoDB: An assertion was raised during rollback of an
         ALTER TABLE operation that dropped and added a secondary
         index. (Bug #22005726)

       * Partitioning: In some cases, an issue with partition
         pruning being attempted a second time during optimization
         after all partitions had already been pruned at parsing
         time led to an assert. (Bug #23194259)

       * Replication: Replication slaves could exit trying to
         apply an UPDATE row event containing virtual generated
         columns received from a master that was set to
         binlog_row_image=minimal. (Bug #23604483)

       * Replication: When using row-based replication and InnoDB,
         replication slaves reverted to using an older locking
         scheme when a transaction had already acquired an AUTOINC
         lock related to a LOAD FILE or INSERT ... SELECT type of
         statement, reducing replication slave performance. The
         fix ensures that sql_command is set correctly for any of
         the DML events such as WRITE_ROWS_EVENT, UPDATE_EVENT,
         and DELETE_EVENT. (Bug #79324, Bug #22247668)

       * Replication: When using statement-based or mixed binary
         logging format with --read-only=ON, it was not possible
         to modify temporary tables. (Bug #62008, Bug #12818255)
         References: See also: Bug #14294223, Bug #16561483.

       * MySQL Server upgrades performed using RPM packages failed
         when upgrading from MySQL 5.6 Community to MySQL 5.7
         Community or MySQL 5.6 Commercial to MySQL 5.7
         Commercial. (Bug #23736787)

       * On CentOS, mysqld installed from a MySQL Community
         distribution failed to start if a my.cnf file with no
         datadir value specified was used. (Bug #23721277, Bug
         #82049)

       * The -DWITH_EDITLINE=system CMake option failed with
         recent versions of the editline library. (Bug #23708332)

       * Executing prepared statements with the audit_log plugin
         installed could cause a server exit. (Bug #23699991)

       * The sys schema ps_trace_statement_digest() procedure
         failed for statements not supported by EXPLAIN, for
         statements for which EXPLAIN could not find tables, and
         for statements with no digest found during the monitored
         period. (Bug #23621189)

       * A SELECT Performance Schema tables when an internal
         buffer was full could cause a server exit. (Bug
         #23550835, Bug #23298025, Bug #81464)

       * The code for reading character set information from
         Performance Schema statement events tables (for example,
         events_statements_current) did not prevent simultaneous
         writing to that information. As a result, the SQL query
         text character set could be invalid, which could result
         in a server exit. Now an invalid character set causes
         SQL_TEXT column truncation. (Bug #23540008)

       * An error message spelling error was corrected. Thanks to
         Derek Jones for the patch. (Bug #23525874, Bug #81713)

       * In the Performance Schema, allocating a record when a
         buffer was full could lead to a server exit. (Bug
         #23515302)

       * Several issues for Debian/Ubuntu packages were fixed:

            + The mysql-systemd-start script in the
              mysql-community-server package depended on
              mysqladmin for the ping command. Packages including
              this script now are made dependent on the
              mysql-community-client package.

            + The systemd service still used mysqld_safe. It now
              uses mysqld --daemonize.

            + Entering a blank root password during the
              installation process caused installation to hang.

            + MySQL upgrades failed to create a missing data
              directory.

            + In addition, CMake-generated packaging for
              Debian/Ubuntu packages was refactored for improved
              maintainability.
         (Bug #23501369, Bug #81647, Bug #22972977, Bug #21236550,
         Bug #21228746, Bug #22833016, Bug #23582336)

       * A buffer overflow in the regex library was fixed. (Bug
         #23498283)

       * Upgrading from native MySQL 5.6 Debian/Ubuntu packages to
         Oracle-supplied MySQL 5.7 packages caused server restart
         failures. (Bug #23498230)

       * The CMake configuration was too aggressive in making
         symbols invisible, resulting in link problems with GCC
         5.3 on Solaris. (Bug #23344916, Bug #81593)

       * Audit log filtering against the user was performing
         comparisons against USER(), not CURRENT_USER(). (Bug
         #23344762)

       * After upgrading only the server using RPM packages, the
         server could fail to start, complaining about a bad
         errmsg.sys file. (Bug #23338603)
         References: This issue is a regression of: Bug #18518216.

       * Several issues were addressed in the sys schema stored
         procedures that show enabled or disabled Performance
         Schema setup:

            + Enabled and disabled accounts were shown as
              host@user, not user@host.

            + Disabled users in ps_setup_show_disabled were called
              enabled_users.

            + ps_setup_show_enabled() showed disabled objects.

            + setup_actors content was not filtered (all rows were
              returned whether the actor was enabled or disabled).

            + Output order is more deterministic.
         (Bug #23335880, Bug #22066096, Bug #78874)

       * Upgrading from native Ubuntu 5.7.12 packages to MySQL
         5.7.13 packages failed with conflict messages. (Bug
         #23327563)

       * For debug builds, the server exited abnormally if a
         shutdown command was issued while the audit_log plugin
         was loaded and an active connection existed. (Bug
         #23310864)

       * The server could fail to interpret expired passwords as
         expired. (Bug #23291841)

       * Certain arguments to NAME_CONST() could cause a server
         exit. (Bug #23279858)

       * For unit-testing with the MySQL test suite, the make
         unit-test command is no longer available. The ctest
         program should be used instead. See Unit Tests Added to
         Main Test Runs 
(http://dev.mysql.com/doc/mysqltest/2.0/en/unit-tests-from-mtr.html).
         (Bug #23273434)

       * Audit log plugins (including query rewrite plugins, which
         use the audit API) were being acquired and released per
         statement, negatively affecting scalability. To improve
         performance, these plugins now are acquired once and
         released only when the connection ends. (Bug #23236404,
         Bug #81298)

       * mysql-test-run.pl now has a --manual-boot-gdb option that
         is similar to --boot-gdb but attaches the debugger to the
         server during the bootstrapping process, permitting the
         use of a remote debugger. (Bug #23090633)

       * The -fexpensive-optimizations option to GCC caused ARM64
         and PowerPC builds to compute floating-point operations
         slightly differently from other platforms. CMake now
         checks for this problem and disables the option as
         necessary. (Bug #23046775)

       * The test_service_sql_api.test_session_general_log test
         case now cleans up the general_log table by truncating it
         at the end of the test. Thanks to Daniel Black for the
         patch. (Bug #23021111, Bug #80895)

       * Lines written to the error log had no space separating
         the timestamp and thread ID columns if the thread ID took
         five or more characters. (Bug #23005009, Bug #80854)

       * For the innodb_buffer_stats_by_schema and
         innodb_buffer_stats_by_table sys schema views, the
         pages_hashed and pages_old columns were incorrect. Thanks
         to Tsubasa Tanaka for the patch. (Bug #22988461, Bug
         #80833)

       * An incorrect result could be returned for a query using a
         merged derived table or a view when compared to a similar
         query using a base table directly, if the query included
         a WHERE condition in a scalar subquery inside a HAVING
         condition of the main query block. (Bug #22967439)

       * ST_GeomFromGeoJSON() treated JSON NULL as invalid input.
         Now it treats JSON NULL as SQL NULL and thus returns SQL
         NULL for JSON NULL input. (Bug #22930020, Bug #80712)

       * For the host_summary_by_statement_latency and
         x$host_summary_by_statement_latency sys schema views, the
         max_latency column was incorrect. (Bug #22848110, Bug
         #80569)

       * ST_Distance() could raise an assertion for NULL return
         values. (Bug #22760390)

       * In the absence of SQL_CALC_FOUND_ROWS, FOUND_ROWS() for a
         UNION statement always returned the actual number of rows
         found even when LIMIT was present. (Bug #22602381, Bug
         #80148)

       * A statement containing a format specifier resulted in a
         server exit when the query rewrite plugin tried to log
         the statement. (Bug #22601485)

       * With the query cache enabled, executing a prepared
         statement with CURSOR_TYPE_READ_ONLY and then again with
         CURSOR_TYPE_NO_CURSOR caused the server to return an
         error. (Bug #22559575, Bug #80026)

       * mysql_real_connect() was not thread-safe when invoked
         with the MYSQL_READ_DEFAULT_FILE or
         MYSQL_READ_DEFAULT_GROUP option enabled. (Bug #22322504,
         Bug #79510)

       * With GTIDs enabled, XA COMMIT on a disconnected XA
         transaction within a multiple-statement transaction
         raised an assertion. (Bug #22173903)

       * The sys schema create_synonym_db() function failed if the
         synonym name was a reserved word or contained backtick
         (`) characters. (Bug #22011361, Bug #78823)

       * The sys schema host_summary view could fail with a
         division-by-zero error. (Bug #21970078)

       * The GCC workaround for compiling on ARM64 added by Bug
         #21552524 is needed only for GCC before 5.2.1. (Bug
         #21845828)
         References: See also: Bug #21552524.

       * The sys schema format_path() function replaced substrings
         of the path name argument without verifying that the
         substrings were delimited by path name separators.
         Replacement now works correctly, including on Windows. A
         consequence is that backslashes in Windows path names are
         no longer converted to forward slashes in the result.
         (Bug #21512106)

       * MySQL now supports compiling using the GCC __atomic
         builtins introduced in GCC 4.7 that permit a more
         efficient implementation of the MySQL atomics API. These
         __atomic builtins are only used for platforms where the
         old GCC __sync builtins are not available, such as
         PowerPC where the server otherwise would not build. (Bug
         #21221500)

       * If a stored function updated a view for which the view
         table had a trigger defined that updated another table,
         it could fail and report an error that an existing table
         did not exist. (Bug #21142859, Bug #76808)

       * mysql_upgrade failed to upgrade the sys schema if a sys
         database directory existed but was empty. (Bug #81352,
         Bug #23249846, Bug #22875519)

       * The bundled Protobuf sources (under the extra directory)
         were upgraded from version 2.6.0 to 2.6.1. (Bug #81280,
         Bug #23213376)

       * Protobuf is currently used only by the X plugin, but
         MySQL builds built the protobuf libraries and executables
         even if X plugin building was disabled with
         -DWITH_RAPID=0. (Bug #81066, Bug #23097750)

       * On Solaris, a misaligned memory buffer could cause a
         server exit when selecting from the global_status
         Performance Schema table. (Bug #81065, Bug #23097305)

       * A compilation error was corrected for a make_link() call
         when compiling in C++11 mode. Thanks for Daniel Black for
         the contribution. (Bug #80996, Bug #23080289)

       * Two mysql-test-run.pl tests (ctype_gb18030_binlog and
         ctype_ldml) failed to produce repeatable output due to
         improper cleanup. Thanks to Daniel Black for the patch.
         (Bug #80896, Bug #23021095)

       * MySQL failed to build with GCC 6 using the default mode
         for C++ of -std=gnu++14. The CMake configuration has been
         adjusted to explicitly set the mode to -std=gnu++03 for
         GCC 6. (Bug #80371, Bug #22732697)

       * Ubuntu packages create the root user account using the
         auth_socket authentication plugin to achieve
         secure-by-default installation if installation was done
         with a blank root password. However, auth_socket was
         being used even if the password was not blank. (Bug
         #80137, Bug #22594846, Bug #23321113, Bug #81518)

       * Compiling the InnoDB memcached plugin did not work on
         some platforms where MySQL was configured using
         -DWITH_LIBEVENT=system. (Bug #80073, Bug #22573379, Bug
         #23567441)

       * The client-side plugin deinitialization function
         signature was changed from int (*deinit)() to int
         (*deinit)(void) to avoid warnings when compiling with
         -Wstrict-prototypes. (Bug #78177, Bug #21680094, Bug
         #81419, Bug #23282498)
