Subject:MySQL Shell 1.0.10 GA has been released
View as plain text  
Dear MySQL Users,

A new GA (general availability) version of MySQL Shell
(a component of the MySQL Server) has been made
available: MySQL Shell 1.0.10 GA. The MySQL Shell is provided
under Oracle's dual-license.

MySQL Shell is an interactive JavaScript, Python and SQL console
interface, supporting development and administration for the MySQL
Server. It provides scriptable API that supports the creation and
management of MySQL InnoDB clusters, as well as a modern fluent CRUD
API for the MySQL Document Store.

The AdminAPI provides an integrated solution for high availability and
scalability using InnoDB based MySQL databases, without requiring
advanced MySQL expertise.

The Document Store DevAPI enables developers and DBAs to create
"schema-less" JSON document collections and perform Create, Update,
Read, Delete (CRUD) operations on those collections with little to
no knowledge of the SQL language.

Additionally, MySQL Shell provides partial compatibility with the
mysql command line client by supporting many of the same command line
options. As with the mysql command line, MySQL Shell can also be used
to connect to and send SQL commands to pre-5.7.12 versions of the
MySQL server using the standard MySQL network protocol.

For more information about how to configure and work with an InnoDB cluster

For more information about how to use MySQL Shell and the MySQL Document
Store support see

For full documentation on MySQL Server, MySQL Shell and related topics,

If you want to write applications that use the the CRUD based X DevAPI
use the latest MySQL Connectors for your language of choice. You can
also find documentation about Connectors in the MySQL documentation

Changes in MySQL Shell 1.0.10 (2017-07-28, General Availability)

    Security Notes

      * Security Fix: The linked OpenSSL library for MySQL Shell
        Commercial has been updated to version 1.0.2l. Issues
        fixed in the new OpenSSL version are described at
        This change does not affect Oracle-produced MySQL
        Community builds of MySQL Shell, which use the yaSSL
        library instead. (Bug #26284262)

      * Security Fix: Running queries on servers using MySQL 8
        against a table with a text column caused an unexpected

    Functionality Added or Changed

      * The clusterAdminType option of the dba.createCluster()
        was unused and has been removed. (Bug #25585027)

      * The --help message now displays all short-form options.
        The --help message now displays complete information for
        the --json option.'options') now returns usable information
        about mysqlsh options.'checkInstanceState') now reports correct
        information.'addInstance') and'rejoinInstance') now report complete
        help() now reports complete information for all AdminAPI
        and Shell commands. (Bug #24841493, Bug #24910540, Bug
        #24841749, Bug #25701345, Bug #24977542, Bug #25268410,
        Bug #25266846)

      * Calling the modify() or remove() function without a
        parameter caused the function to be executed against the
        whole collection, which could cause unexpected results
        such as deleting all rows in a table. To avoid this and
        make the behavior consistent with update() and delete(),
        a client-side exception is now thrown if the modify() or
        remove() function is called without a parameter. Now, to
        execute the modify() or remove() function against a
        collection call them with an expression that evaluates to
        true, for example remove('true') or modify('true').

    Bugs Fixed

      * When making cluster topology or membership changes,
        AdminAPI was not taking into consideration the value of
        group_replication_group_name, which could lead to
        incorrect, non-deterministic results in scenarios such as
        split-brains. Now, the following commands validate the
        InnoDB cluster Metadata and the corresponding instance's
        group_replication_group_name value:

           + dba.getCluster()

           + Cluster.rejoinInstance()

           + Cluster.forceQuorumUsingPartitionOf()
        If the values of group_replication_group_name do not
        match, the commands abort with an error.
        dba.rebootClusterFromCompleteOutage() was also updated to
        ensure that the group_replication_group_name variable has
        not been changed before rejoining the instance. (Bug

      * AdminAPI now always uses the active user value for the
        current mysqlsh session, whether the value was explicitly
        specified by the user or is the result of an implicit
        default used by mysqlsh. (Bug #26132527)

      * The addInstance() function was failing when run against a
        server using MySQL 8. (Bug #26085799)

      * Executing AdminAPI commands on a server with a version of
        Python lower than 2.7 was failing without the correct
        error message. (Bug #25975317)

      * The checks performed by the AdminAPI upon issuing
        dba.rebootClusterFromCompleteOutage() were more strict
        than those required by Group Replication. Now, the
        AdminAPI considers tables with a Primary Key Equivalent
        (such as a Non Null Unique Key) as compatible, matching
        the current requirement for Group Replication. (Bug

      * Executing dba.createCluster() on an instance with
        sql_mode=ANSI_QUOTES failed with an error. (Bug
        References: See also: Bug #25990172.

      * The server version is now displayed as part of the
        "Connected to" message. (Bug #25824753)

      * When using MySQL Shell on Windows any files created or
        opened, for example those used during
        dba.createSandboxInstance(), could not be deleted. (Bug

      * Queries that used an expression of the form
        collection.find(identifier IN identifier) caused an
        abnormal mysqlsh exit. (Bug #25754078)

      * If AdminAPI functions were interrupted, for example with
        control-C on Unix, the exit code returned by the process
        was 1 instead of the expected one for terminated
        processes, for example SIGINT. (Bug #25728759)

      * The previous limitation of auto_increment_increment being
        set according to the random 32-bit unsigned integers used
        for the server-id system variable has been resolved. Now,
        when operating in single-primary mode
        auto_increment_increment is set to 1 and
        auto_increment_offset is set to 2. In multi-primary mode
        auto_increment_increment is set to 7 and
        auto_increment_offset is set to 1 plus the server_id
        modulo 7. (Bug #25724564)

      * The randomly generated passwords used by internal users
        were not compatible with instances running the Password
        Validation plugin. (Bug #25714751)

      * The help for dba.configureLocalInstance(instance[,
        options]) has been improved to describe the returned JSON
        object. (Bug #25703028)

      * The options in the MySQL Shell options dictionary are now
        fully documented. (Bug #25701345)

      * Issuing configureLocalInstance() when using a URI that
        contained a user without the correct privileges resulted
        in an incorrect new user being created. Now, if the user
        in configureLocalInstance() URI does not have enough
        privileges to grant all the necessary privileges for the
        new user chosen during the interactive wizard
        configuration the user is not created. (Bug #25614855)

      * Issuing Cluster.rescan() resulted in non-determinstic
        behavior which could produce incorrect JSON output,
        showing an instance that was already part of the cluster
        as belonging to the newlyDiscoveredInstances[] list and
        to the unavailableInstances[] list. This also resulted in
        MySQL Shell prompting to add or remove the instance from
        the cluster. (Bug #25534693)

      * AdminAPI functions now accept the standard connection
        parameters as used by shell.connect. New validations have
        been added for when require_secure_transport is ON, now
        it is not possible to to create a cluster with
        memberSslMode:DISABLED or to add an instance with
        require_secure_transport=ON to a cluster where
        memberSslMode:DISABLED. (Bug #25532298)

      * The parsing of account names, for example when passing
        the clusterAdmin option to dba.configureLocalInstance()
        has been improved. (Bug #25528695)

      * Issuing configureLocalInstance() twice could fail. (Bug

      * When passing the rejoinInstances[] option to
        dba.rebootClusterFromCompleteOutage(), if no
        rejoinInstances[] option was specified then members were
        being incorrectly handled during the rebuild. Now,
        instances that are eligible to be added to the
        rejoinInstances[] list but that are specified in the
        removeInstances[] list are skipped by the interactive
        wizard that tries to automatically build a
        rejoinInstances[] list if one was not provided. This fix
        also ensures that both interactive and non interactive
        use of MySQL Shell correctly verify the rejoinInstances[]
        list does not contain a non reachable instance. (Bug

      * When using dba.deploySandboxInstance() and passing in
        sandboxDir, the specified path must not exceed 89
        characters. (Bug #25485035)

      * shell.connect() did not report an error if an invalid
        argument was used. An ArgumentError is now issued for any
        invalid argument.
        The following mutually exclusive pairs of options are now
        checked, and an error is issued if both are specified:

           + --password and --dbPassword

           + --user and --dbUser

           + --port and --socket
        (Bug #25268670)
        References: See also: Bug #24911173.

      * Issuing removeInstance() on the last member of a cluster,
        and particularly the seed member, was resulting in a
        cluster that could not be dissolved. Now, issuing
        removeInstance() on the last member of a cluster results
        in an error, and you must use dissolve() on that instance
        to ensure the cluster is correctly dissolved. (Bug

      * removeInstance() resulted in unexpected behavior in some
        cases, for example when an empty password was passed as
        part of the URI to the instance. (Bug #25111911)

      * The default for prompts has been made more consistent.
        (Bug #25039886)

      * A number of issues with the output of"prompt") have been corrected. (Bug #25026855,
        Bug #25242638, Bug #25676343, Bug #25176769)

      * The usage of the terms global session and active session
        have been made more consistent in the user interface.
        (Bug #24954546)

      * The removeInstance() was not working on stopped instances
        and it was not possible to remove an unavailable instance
        from the cluster. The fix adds a new option force to the
        removeInstance() command to enable you to remove
        instances from the metadata that are permanently not
        available, avoiding obsolete data from being kept in the
        metadata of the cluster. In addition the error message
        provided when not using the force option has been
        improved and the online help for the removeInstance() was
        also updated accordingly. (Bug #24916064)

      * Unsigned data could be incorrectly read from the
        database. (Bug #24912358)

      * MySQL Shell now displays an invalid year as 0000,
        matching the behavior of the MySQL prompt, rather than as
        0. (Bug #24912061)

      * MySQL Shell did not display fractional seconds for values
        in DATETIME columns. (Bug #24911885)

      * The parsing of Unix sockets provided as part of a URI has
        been improved. (Bug #24905066)

      * Creating Classic sessions that connect using Unix sockets
        now uses the correct defaults such as hostname. This
        resolves the previous limitation of using Unix sockets to
        connect to InnoDB cluster instances. See MySQL Shell Connections
        for information on how the defaults are
        applied to socket connections. (Bug #24848763, Bug
        References: See also: Bug #24911068.

      * Some issues with the MySQL Shell command line help output
        were fixed. (Bug #24841749, Bug #24841493, Bug #24910540)

      * If an error occurs now both the error number and error
        text are correctly displayed. (Bug #24816578)

      * URIs were incorrectly parsed in MySQL Shell when
        passwords were hidden. (Bug #24793956)

      * The error messages generated by issuing
        dba.deployLocalInstance() against an unsuitable or
        incompatible instance have been improved. (Bug #24598272)

      * The dba.createCluster(), dba.getCluster(), and
        dba.rebootClusterFromCompleteOutage() functions have been
        updated to validate the cluster name, using the following

           + Name must start with a letter or the _ character

           + Name can only contain alphanumeric characters and
             the _ character

           + Cannot be longer than 40 characters

           + Cannot be empty
        The Cluster.addInstance() function has been updated to
        validate the label used on an instance in the cluster,
        using the following rules:

           + Label can only contain alphanumerics or the _

           + Cannot be longer than 256 characters

           + Cannot be empty
        (Bug #24565242)

      * Using the --dba enableXProtocol option to install X
        Plugin was failing. (Bug #23508428)

      * mysqlsh stopped responding if the \source command was
        given a directory (rather than file) argument. (Bug
        #23097932, Bug #81060)

      * When using cluster.rejoinInstance() any user specified in
        the connection string passed in was being ignored and the
        connection was using the root user. (Bug #85567, Bug

      * On an instance configured as a multi-threaded slave, in
        other words slave_parallel_workers set to greater than 0,
        and with slave_parallel_type=DATABASE,
        dba.checkInstanceConfiguration() was not detecting that
        the instance was not correctly configured for InnoDB
        cluster usage.

      * If removeInstance() failed due to a connection error, an
        error was reported but the instance was incorrectly
        removed from the InnoDB cluster metadata, and remained
        part of the replication group. The fix ensures the
        metadata is correctly updated according to the result of

      * In a situation where a new primary instance was elected,
        adding a new instance to the cluster resulted in an error
        due to a failed connection to the previous primary

      * The functions that modify server variables, such as
        dba.createCluster() and dba.validateInstance() now
        provide more information in interactive mode output and
        log output about server variables which are changed when

      * Deploying instances to paths with directories that
        contained spaces was failing without error. Use double
        backslash to specify such paths, for example
        D:\\Cluster\\foo bar.

      * The Cluster object obtained from functions such as
        dba.createCluster() or dba.getCluster() became unusable
        once the Shell session in which the object was created is
        was connected to a different server. The fix modifies the
        Cluster object so that:

           + The Cluster object holds an internal reference to
             the Session from which it was created or retrieved.

           + AdminAPI functions that modify the Cluster are made
             using the session referenced by the object.
