Subject:MySQL Community Server 5.6.35 has been released
View as plain text  
Dear MySQL users,

MySQL Server 5.6.35, a new version of the popular Open Source
Database Management System, has been released. MySQL 5.6.35 is
recommended for use on production systems.

For an overview of what's new in MySQL 5.6, please see


      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 5.6.35 on new servers or upgrading
to MySQL 5.6.35 from previous MySQL releases, please see

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

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:

The following section lists the changes in the MySQL 5.6 since
the release of MySQL 5.6.34. It may also be viewed

Changes in MySQL 5.6.35 (2016-12-12)

      * MySQL Enterprise Notes

      * Security Notes

      * Functionality Added or Changed

      * Bugs Fixed

    MySQL Enterprise Notes

      * Enterprise Encryption for MySQL Enterprise Edition now
        enables server administrators to impose limits on maximum key
        length by setting environment variables. These can be used to
        prevent clients from using excessive CPU resources by passing
        very long key lengths to key-generation operations. For more
        information, see Enterprise Encryption Usage and Examples
       (Bug #19687742)

    Security Notes

      * Incompatible Change: These changes were made to

           + Unsafe use of rm and chown in mysqld_safe could result in
           privilege escalation. chown now can be used only when the
           target directory is /var/log. An incompatible change is that
           if the directory for the Unix socket file is missing, it is no
           longer created; instead, an error occurs. Due to these
           changes, /bin/bash is required to run mysqld_safe on Solaris.
           /bin/sh is still used on other Unix/Linux platforms.

           + The --ledir option now is accepted only on the command line,
           not in option files.

           + mysqld_safe ignores the current working directory.  Other
           related changes:

           + Initialization scripts that invoke mysqld_safe pass
           --basedir explicitly.

           + Initialization scripts create the error log file only if the
           base directory is /var/log or /var/lib.

           + Unused systemd files for SLES were removed. (Bug #24483092,
           Bug #25088048) References: See also: Bug #24464380, Bug

      * MySQL Server now includes a plugin library that enables
        administrators to introduce an increasing delay in server
        response to clients after a certain number of consecutive failed
        connection attempts. This capability provides a deterrent that
        slows down brute force attacks that attempt to access MySQL user
        accounts. For more information, see The Connection-Control Plugin

      * OpenSSL is ending support for version 1.0.1 in December
        2016; see
        Consequently, MySQL Commercial Server builds now use version
        1.0.2 rather than version 1.0.1, and the linked OpenSSL library
        for the MySQL Commercial Server has been updated from version
        1.0.1 to version 1.0.2j. For a description of issues fixed in
        this version, see This change
        does not affect the Oracle-produced MySQL Community build of
        MySQL Server, which uses the yaSSL library instead.

    Functionality Added or Changed

      * InnoDB: By default, InnoDB reads uncommitted data when
        calculating statistics. In the case of an uncommitted transaction
        that deletes rows from a table, InnoDB excludes records that are
        delete-marked when calculating row estimates and index
        statistics, which can lead to non-optimal execution plans for
        other transactions that are operating on the table concurrently
        using a transaction isolation level other than READ UNCOMMITTED.
        To avoid this scenario, a new configuration option,
        innodb_stats_include_delete_marked, can be enabled to ensure that
        InnoDB includes delete-marked records when calculating persistent
        optimizer statistics. (Bug #23333990)

      * Unit testing now uses Google Mock 1.8. (Bug #24572381,
        Bug #82823)

    Bugs Fixed

      * Incompatible Change: A change made in MySQL 5.7.8 for
        handling of multibyte character sets by LOAD DATA was reverted
        due to the replication incompatibility (Bug #24487120, Bug
        #82641) References: See also: Bug #23080148.

      * InnoDB: The GCC mach_parse_compressed function should
        load one to five bytes depending on the value of the first byte.
        Due to a GCC bug, GCC 5 and 6 emit code to load four bytes before
        the first byte value is checked (GCC Bug #77673). A workaround
        prevents this behavior.  Thanks to Laurynas Biveinis for the
        patch. (Bug #24707869, Bug #83073)

      * InnoDB: Due to a glibc bug, short-lived detached threads
        could exit before the caller had returned from pthread_create(),
        causing a server exit.  Thanks to Laurynas Biveinis for the
        patch. (Bug #24605956, Bug #82886)

      * InnoDB: An error during a table-rebuilding operation on a
        table with only a generated clustered index (GEN_CLUST_INDEX)
        raised and assertion due to an error called with an invalid key
        name. (Bug #24444831)

      * InnoDB: On a table without an explicitly defined primary
        key, InnoDB did not replace the implicit clustered index
        (GEN_CLUST_INDEX) when a unique key was defined on a NOT NULL
        column. (Bug #24397406)

      * InnoDB: InnoDB failed to free memory used by the
        full-text optimizer thread. (Bug #24331265)

      * InnoDB: SHOW ENGINE INNODB STATUS output showed a
        "cleaning up" state for an idle thread. Thread state information
        was not reset after statement execution. (Bug #21974225, Bug

      * InnoDB: After a server restart, concurrent INSERT
        operations a table with an auto-increment primary key resulted in
        a duplicate entry error. The current auto-increment value was not
        changed after auto_increment_increment and auto_increment_offset
        settings were modified. (Bug #20989615, Bug #76872)

      * Replication: Tables with special DEFAULT columns, such as
        DEFAULT CURRENT_TIMESTAMP, that existed only on a slave were not
        being updated when using row-based replication
        (binlog_format=ROW). (Bug #22916743)

      * Replication: Enabling semisynchronous replication when a
        server was during the commit stage could cause the master to stop
        unexpectedly. This was related to the patch for Bug# 75570. (Bug

      * Replication: The fix for Bug #81657 was correctly merged
        into MySQL 5.6. (Bug #83124, Bug #24715790)

      * Some Linux startup scripts did not process the datadir
        setting correctly. (Bug #25159791)

      * CREATE TABLE with a DATA DIRECTORY clause could be used
        to gain extra privileges. (Bug #25092566)

      * OEL RPM packages now better detect which platforms have
        multilib support (for which 32-bit and 64-bit libraries can be
        installed). Thanks to Alexey Kopytov for the patch. (Bug
        #24925181, Bug #83457)

      * Compiling MySQL using Microsoft Visual Studio 2015
        Version 14.0.25420.1 in relwithdebinfo mode failed with linking
        errors. (Bug #24748505)

      * Warnings occurring during CREATE TABLE ... SELECT could
        cause a server exit. (Bug #24595992)

      * For segmentation faults on FreeBSD, the server did not
        generate a stack trace. (Bug #24566529, Bug #23575445, Bug

      * The .mylogin.cnf option file is intended for use by
        client programs, but the server was reading it as well.  The
        server no longer reads it. (Bug #24557925)

      * If mysqladmin shutdown encountered an error determining
        the server process ID file, it displayed an error message that
        did not clearly indicate the error was nonfatal. It now indicates
        that execution continues. (Bug #24496214)

      * The data structure used for ZEROFILL columns could
        experience memory corruption, leading eventually to a server
        exit. (Bug #24489302)

      * Use of very long subpartition names could result in a
        server exit. Now partition or subpartition names larger than 64
        characters produce an ER_TOO_LONG_IDENT error. (Bug #24400628,
        Bug #82429)

      * On Solaris, gettimeofday() could return an invalid value
        and cause a server shutdown. (Bug #23499695)

      * A union query resulting in tuples larger than
        max_join_size could result in a server exit. (Bug #23303485)

      * The optimizer could choose ref access on a secondary
        index rather than range access on the primary key, even when the
        cost was higher. (Bug #23259872, Bug #81341)

      * For some deeply nested expressions, the optimizer failed
        to detect stack overflow, resulting in a server exit.  (Bug

      * When taking the server offline, a race condition within
        the Performance Schema could lead to a server exit. (Bug

      * The Performance Schema
        events_statements_summary_by_digest table could contain multiple
        rows for the same statement digest and schema combination, rather
        than the expected single (unique) row. (Bug #22320066, Bug

      * For debug builds: Adding a unique index to a POINT NOT
        NULL column triggered a warning and the key was not promoted to a
        primary key. Creating a unique index on a different non-NULL
        column in the same table then raised an assertion. (Bug
        #19635706, Bug #24469860)

      * Compiling using Clang 3.5 or higher with AddressSanitizer
        (ASAN) enabled caused the gen_lex_hash utility to abort on Clang
        LeakSanitizer memory leak check failures. (Bug #76351, Bug
        #20720615, Bug #22558597, Bug #80014)

      * Miscalculation of memory requirements for qsort
        operations could result in stack overflow errors in situations
        with a large number of concurrent server connections. (Bug
        #73979, Bug #19678930, Bug #23224078)
