Subject:MySQL Shell 8.0.0-dmr has been released
View as plain text  
Dear MySQL users,

This is the first development release version of MySQL Shell 8.0
(a component of the MySQL Server). 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.

For more information on the APIs provided with MySQL Shell
see https://dev.mysql.com/doc/dev/mysqlsh-api-javascript/8.0/
and https://dev.mysql.com/doc/dev/mysqlsh-api-python/8.0/.

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
see https://dev.mysql.com/doc/refman/en/mysql-innodb-cluster-userguide.html

For more information about how to use MySQL Shell and the MySQL Document
Store support see https://dev.mysql.com/doc/refman/en/document-store.html

For full documentation on MySQL Server, MySQL Shell and related topics,
see http://dev.mysql.com/doc/refman/en/

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
site.

For more information about how to download MySQL Shell 8.0.0 dmr, see

We welcome and appreciate your feedback and bug reports, see

Enjoy!

Changes in MySQL Shell 8.0.0 (2017-07-14, Development Milestone)


    Functionality Added or Changed

      * 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

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

      * When using MySQL Shell on Windows any files created or
        opened, for example those used during
        dba.createSandboxInstance(), could not be deleted. (Bug
        #25789094)

      * 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)

      * 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.

      * 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)

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

      * 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)

      * 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
(http://dev.mysql.com/doc/refman/8.0/en/mysql-shell-connections.html)
        for information on how the defaults are
        applied to socket connections. (Bug #24848763, Bug
        #26036466)
        References: See also: Bug #24911068.

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

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

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

      * 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
        removeInstance().

      * 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
        instance.

      * 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
        executed.

      * 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.
