MySQL Connector/ODBC 8.0.14 has been released

Posted on by

Dear MySQL users,

MySQL Connector/ODBC 8.0.14 is a new version in the MySQL Connector/ODBC 8.0 series,
the ODBC driver for the MySQL Server.

The available downloads include both a Unicode driver and an ANSI driver based on the
same modern codebase. Please select the driver type you need based on the type of your
application – Unicode or ANSI. Server-side prepared statements are enabled by default.
It is suitable for use with any MySQL server version from 5.5.

This release of the MySQL ODBC driver is conforming to the ODBC 3.8 specification.
It contains implementations of key 3.8 features, including self-identification
as a ODBC 3.8 driver, streaming of output parameters (supported for binary types
only), and support of the SQL_ATTR_RESET_CONNECTION connection attribute (for the
Unicode driver only).

The release is now available in source and binary form for a number of platforms
from our download pages at

https://dev.mysql.com/downloads/connector/odbc/

For information on installing, please see the documentation at

https://dev.mysql.com/doc/connector-odbc/en/connector-odbc-installation.html

Changes in MySQL Connector/ODBC 8.0.14 (2019-01-21, General Availability)

Functionality Added or Changed

* A new ENABLE_LOCAL_INFILE connection option was added to
the connection string, DSN, and GUI. Disabled by default,
set ENABLE_LOCAL_INFILE=1 to enable LOAD DATA operations.
This toggles the MYSQL_OPT_LOCAL_INFILE mysql_options()
option.
The connection string overrides the DSN value if both are
set.

* MySQL Connector/ODBC is now compatible with MSVC 2017,
while retaining compatibility with MSVC 2015:

+ Previously, Connector/ODBC binary distributions were
compatible with projects built using MSVC 2015.
Binary distributions now are compatible with
projects built using MSVC 2017 or 2015.

+ Previously, Connector/ODBC source distributions
could be built using MSVC 2015. Source distributions
now can be built using MSVC 2017 or 2015.

+ Previously, the MSI installer accepted the Visual
C++ Redistributable for Visual Studio 2015. The MSI
installer now accepts the Visual C++ Redistributable
for Visual Studio 2017 or 2015.

* Two informative text files were added: INFO_BIN contains
information about the build environment used to produce
the distribution, and INFO_SRC provides information about
the product version and the source repository from which
the distribution was produced. Source distributions
include the INFO_SRC file only.

MySQL Connector/Node.js 8.0.14 has been released

Posted on by

Dear MySQL users,

MySQL Connector/Node.js is a new Node.js driver for use with the X
DevAPI. This release, v8.0.14, is a maintenance release of the
MySQL Connector/Node.js 8.0 series.

The X DevAPI enables application developers to write code that combines
the strengths of the relational and document models using a modern,
NoSQL-like syntax that does not assume previous experience writing
traditional SQL.

MySQL Connector/Node.js can be downloaded through npm (see
https://www.npmjs.com/package/@mysql/xdevapi for details) or from
https://dev.mysql.com/downloads/connector/nodejs/.

To learn more about how to write applications using the X DevAPI, see
http://dev.mysql.com/doc/x-devapi-userguide/en/. For more information
about how the X DevAPI is implemented in MySQL Connector/Node.js, and
its usage, see http://dev.mysql.com/doc/dev/connector-nodejs/.

Please note that the X DevAPI requires at least MySQL Server version
8.0 or higher with the X Plugin enabled. For general documentation
about how to get started using MySQL as a document store, see
http://dev.mysql.com/doc/refman/8.0/en/document-store.html.

Changes in MySQL Connector/Node.js 8.0.14 (2019-01-21, General Availability)

Functionality Added or Changed

* Removed deprecation notices from the count() methods.

* Setting the default schema via the connection now sets
the default schema on the server; meaning, subsequent
queries executed using session.sql() do not need to
specify the schema.

Bugs Fixed

* Setting the default schema with the connection URI using
a schema name that contained special characters (that
would need to be percent-encoded) would result in the
percent-encoded name being used instead of the original
one (e.g. “%25%26%5E*%5E_” instead of “%&^*^_”). (Bug
#28990682)

* An error is once again thrown if sslOption’s ‘ca’ is
different than the certificate authority used to sign the
server certificate, or if the server certificate has been
revoked. (Bug #28977649)

* Attempting to use false-like values such as 0, false,
null, and undefined would emit errors when updating or
inserting documents in a collection or rows in a table.
Additionally, now boolean values become numeric values
(true=1, false=0) while null and undefined are converted
to MySQL’s NULL type. (Bug #28970727, Bug #93315)

* Collection.existsInDatabase() always returned true if any
other collection existed in the database. (Bug #28745240)

* Configuring a default schema from the connection string
would create the schema if it did not exist. Now, an
“Unknown database” error is thrown instead.

* An unexpected notice could result in an unexpected halt
of the client.

MySQL Connector/C++ 8.0.13 has been released

Posted on by
Dear MySQL users,

MySQL Connector/C++ 8.0.13 is a new release version of the MySQL
Connector/C++ 8.0 series.

Connector/C++ 8.0 can be used to access MySQL implementing Document Store or in a traditional way, using SQL queries. It allows writing both C++ and plain C applications using X DevAPI and X DevAPI for C. It also supports the legacy API of Connector/C++ 1.1 based on JDBC4.

To learn more about how to write applications using X DevAPI, see “X DevAPI User Guide”

https://dev.mysql.com/doc/x-devapi-userguide/en/

See also “X DevAPI Reference” at

https://dev.mysql.com/doc/dev/connector-cpp/devapi_ref.html

and “X DevAPI for C Reference” at

https://dev.mysql.com/doc/dev/connector-cpp/xapi_ref.html

For generic information on using Connector/C++ 8.0, see

https://dev.mysql.com/doc/dev/connector-cpp/

For general documentation about how to get started using MySQL
as a document store, see

http://dev.mysql.com/doc/refman/8.0/en/document-store.html

To download MySQL Connector/C++ 8.0.13, see the “Generally Available (GA)
Releases” tab at

https://dev.mysql.com/downloads/connector/cpp/



Changes in MySQL Connector/C++ 8.0.13 (2018-10-22, General Availability)

* Character Set Support

* Packaging Notes

* X DevAPI Notes

* Functionality Added or Changed

* Bugs Fixed

Character Set Support


* For connections to the server made using the legacy JDBC
API (that is, not made using X DevAPI or X DevAPI for C),
the default connection character set is now utf8mb4
rather than utf8. Connections to the server made using X
DevAPI or X DevAPI for C continue to use the connection
character set determined by the server. (Bug #28204677)

Packaging Notes


* Connector/C++ 32-bit MSI packages are now available for
Windows. These 32-bit builds enable use of the legacy
JDBC connector.

* Connector/C++ compressed tar file packages are now
available for Solaris.
It is also possible to build Connector/C++ from source on
Solaris. For platform-specific build notes, see Building
Connector/C++ Applications: Platform-Specific Considerations
(http://dev.mysql.com/doc/connector-cpp/8.0/en/connector-cpp-apps-platform-considerations.html).


X DevAPI Notes


* Connector/C++ now provides connection pooling for
applications using X Protocol. This capability is based
on client objects, a new type of X DevAPI object. A
client can be used to create sessions, which take
connections from a pool managed by that client. For a
complete description, see Connecting to a Single MySQL
Server Using Connection Pooling
(http://dev.mysql.com/doc/x-devapi-userguide/en/connecting-connection-pool.html).
X DevAPI example:
using namespace mysqlx;

Client cli("user:password@host_name/db_name", ClientOption::POOL_MAX_SIZE, 7);
Session sess = cli.getSession();

// use sess as before

cli.close();  // close session sess

X DevAPI for C example:
char error_buf[255];
int  error_code;

mysqlx_client_t *cli
= mysqlx_get_client_from_url(
"user:password@host_name/db_name", "{ \"maxSize\": 7 }", error_buf, &error_code);
mysqlx_session_t *sess = mysqlx_get_session_from_client(cli);

// use sess as before

mysqlx_close_client(cli);  // close session sess


* For X DevAPI, a new connect-timeout option can be
specified in connection strings or URIs to indicate a
connection timeout in milliseconds. The
SessionSettings::Options object supports a new
CONNECT_TIMEOUT option.
For X DevAPI for C, the mysqlx_opt_type_t constant is
MYSQLX_OPT_CONNECT_TIMEOUT together with the
OPT_CONNECT_TIMEOUT() macro.
If no timeout option is specified, the default is 10000
(10 seconds). A value of 0 disables the timeout. The
following examples set the connection timeout to 10
milliseconds:
X DevAPI examples:
Session sess("user@host/db?connect-timoeut=10");

Session sess(..., SessionOption::CONNECT_TIMEOUT, 10, ...);

Session sess(
...,
SessionOption::CONNECT_TIMEOUT, std::chrono::milliseconds(10),
...
);

X DevAPI for C example:
mysqlx_session_options_t *opt = mysqlx_session_options_new();
mysqlx_session_option_set(opt, ..., OPT_CONNECT_TIMEOUT(10), ...);

Functionality Added or Changed


* JSON: Connector/C++ now uses RapidJSON for improved
performance of operations that involve parsing JSON
strings. There are no user-visible API changes for X
DevAPI or X DevAPI for C.

Bugs Fixed


* On SLES 15, Connector/C++ installation failed if
libmysqlcppcon7 was already installed. (Bug #28658120)

* Applications that were statically linked to the legacy
JDBC connector could encounter a read access violation at
exit time due to nondeterministic global destruction
order. (Bug #28525266, Bug #91820)

* Configuring with -DCMAKE_BUILD_TYPE=Release did not work
on Linux. (Bug #28045274)

* Field references in .having() expressions could be
interpreted incorrectly and produce errors.
(Bug #26310713)

MySQL Connector/Node.js 8.0.13 has been released

Posted on by

Dear MySQL users,

MySQL Connector/Node.js is a new Node.js driver for use with the X
DevAPI. This release, v8.0.13, is a maintenance release of the
MySQL Connector/Node.js 8.0 series.

The X DevAPI enables application developers to write code that combines
the strengths of the relational and document models using a modern,
NoSQL-like syntax that does not assume previous experience writing
traditional SQL.

MySQL Connector/Node.js can be downloaded through npm (see
https://www.npmjs.com/package/@mysql/xdevapi for details) or from
https://dev.mysql.com/downloads/connector/nodejs/.

To learn more about how to write applications using the X DevAPI, see
http://dev.mysql.com/doc/x-devapi-userguide/en/. For more information
about how the X DevAPI is implemented in MySQL Connector/Node.js, and
its usage, see http://dev.mysql.com/doc/dev/connector-nodejs/.

Please note that the X DevAPI requires at least MySQL Server version
8.0 or higher with the X Plugin enabled. For general documentation
about how to get started using MySQL as a document store, see
http://dev.mysql.com/doc/refman/8.0/en/document-store.html.

Changes in MySQL Connector/Node.js 8.0.13 (2018-10-22, General availability)

Functionality Added or Changed

* To go with the existing asynchronous
mysqlx.getSession(conn_str) method, a new synchronous
mysqlx.getClient(conn_str, options) method was added that
creates a connection pool handler that provides an
asynchronous getSession() method to create and retrieve
connections from the pool. The collection pooling options
are:

+ enabled: enables or disables connection pooling;
boolean and defaults to true.

+ maxSize: maximum number of connections available in
the pool; positive integer and defaults to 25.

+ maxIdleTime: maximum number of milliseconds a
connection can be idle in the queue before being
closed; integer >= 0 and defaults to 0 (infinite).

+ queueTimeout: maximum number of milliseconds a
request will wait for a connection to become
available; integer >= 0 and defaults to 0
(infinite).
This is different than connectTimeout that’s used
for non-pooling. In a pooling scenario, there might
already be connections in the pool and queueTimeout
controls how long to wait for a connection in the
pool.
Example usage:
var mysqlx = require(‘@mysql/xdevapi’)
var client = mysqlx.getClient(
{ user: ‘root’, host: ‘localhost’, port: 33060 },
{ pooling: { enabled: true, maxIdleTime: 5000, maxSize: 25, queueTimeout: 20000 } }
);

client.getSession()
.then(session => {
console.log(session.inspect())
return session.close() // the connection becomes idle in the client pool
})
.then(() => {
return client.getSession()
})
.then(session => {
console.log(session.inspect())
return client.close() // closes all connections and destroys the pool
})

Closing a session attached to the pool makes the
connection available in the pool for subsequent
getSession() calls, while closing (destroying) the pool
effectively closes all server connections.

* Added a connection timeout query parameter. This defines
the length of time (milliseconds) the client waits for a
MySQL server to become available in the given network
addresses. It was added to both the mysqlx.getSession()
(non-pooling sessions) and mysqlx.getClient() (pooling
sessions) interfaces. This option defaults to 10000 (10
seconds). The value 0 disables the timeout so the client
will wait until the underlying socket (platform
dependent) times out.
Similar to other option formatting rules, this option
defined as connection-timeout (kebab-case) for URI
definitions and connectionTimeout (camelCase) for plain
JavaScript configuration objects.
Example usage:
const mysqlx = require(‘@mysql/xdevapi’);
var client = mysqlx.getClient(‘root@localhost?connect-timeout=5000’)
client.getSession()
.catch(err => {
console.log(err.message) // “Connection attempt to the server was aborted. Timeout of 5000 ms was exceeded.”
})

// Or

const mysqlx = require(‘@mysql/xdevapi’);
var client = mysqlx.getClient(‘mysqlx://root:passwd@[localhost:33060, 127.0.0.1:33060]?connect-timeout=5000’)
client.getSession()
.catch(err => {
// connection could not be established after 10 seconds (5 seconds for each server)
console.log(err.message); // All server connection attempts we re aborted. Timeout of 5000 ms was exceeded for each selected server.
});

In a multi-host scenario, the connect-timeout value
applies to each individual host.

Bugs Fixed

* Improved the handling of X Protocol global notices by
properly logging and then ignoring non-fatal errors, and
making the connection unusable for subsequent operations
in the case of a fatal error. (Bug #28653781)

* Calling getCollationName() on non-textual fields, such as
INT, threw the following error “TypeError: Cannot read
property ‘collation’ of undefined”. (Bug #28608923)

* The fields() method did not function with valid
expressions generated by the expr() method. (Bug
#28409639)

* The returned Session.inspect() object now includes the
‘user’ property in addition to the ‘dbUser’ property but
containing the same value. (Bug #28362115)

MySQL Connector/ODBC 8.0.13 has been released

Posted on by

Dear MySQL users,

MySQL Connector/ODBC 8.0.13 is a new version in the MySQL Connector/ODBC 8.0 series, the ODBC driver for the MySQL Server.

The available downloads include both a Unicode driver and an ANSI driver based on the same modern codebase. Please select the driver type you need based on the type of your application – Unicode or ANSI. Server-side prepared statements are enabled by default. It is suitable for use with any MySQL server version from 5.5.

This release of the MySQL ODBC driver is conforming to the ODBC 3.8 specification. It contains implementations of key 3.8 features, including self-identification as a ODBC 3.8 driver, streaming of output parameters (supported for binary types only), and support of the SQL_ATTR_RESET_CONNECTION connection attribute (for the Unicode driver only).

The release is now available in source and binary form for a number of platforms from our download pages at

https://dev.mysql.com/downloads/connector/odbc/

For information on installing, please see the documentation at

https://dev.mysql.com/doc/connector-odbc/en/connector-odbc-installation.html

Changes in MySQL Connector/ODBC 8.0.13 (2018-10-22, General Availability)

Functionality Added or Changed

  • Added dynamic libmysql linking support via the -DMYSQLCLIENT_STATIC_LINKING:BOOL=TRUE|FALSE option; defaults to FALSE to enable dynamic linking.

Bugs Fixed

  • Fixed column metadata handling with Microsoft Access.
    (Bug #28670725, Bug #91856)
  • The following obsolete options were removed: NO_SCHEMA (use NO_CATALOG instead), DISABLE_SSL_DEFAULT (use SSLMODE instead), and SSL_ENFORCE (use SSLMODE instead). (Bug #28407520)
  • The ODBC Driver returned 0 for the SQL_MAX_SCHEMA_NAME_LEN attribute, and now returns 64 as the maximum length for a MySQL schema name.
    (Bug #28385722)
  • Because the MySQL ODBC driver ignored the SQL_RD_OFF value for the SQL_ATTR_RETRIEVE_DATA attribute, it incorrectly kept writing into the data buffers. This led to write access violation errors when data was written into the buffer when the user application explicitly requested not to write there.

MySQL Connector/NET 6.10.8 has been released

Posted on by

Dear MySQL users,

MySQL Connector/NET 6.10.8 is the fifth GA release with .NET Core
now supporting various connection-string options and MySQL 8.0 server
features.

To download MySQL Connector/NET 6.10.8 GA, see the “Generally Available
(GA) Releases” tab at http://dev.mysql.com/downloads/connector/net/

Changes in Connector/NET 6.10.8 (2018-08-14, General Availability)

Functionality Added or Changed

* Optimistic locking for database-generated fields was
improved with the inclusion of the [ConcurrencyCheck,
DatabaseGenerated(DatabaseGeneratedOption.Computed)]
attribute. Thanks to Tony Ohagan for the patch. (Bug
#28095165, Bug #91064)

* All recent additions to .NET Core 2.0 now are compatible
with the Connector/NET 6.10 implementation.

* With the inclusion of the Functions.Like extended method,
scalar-function mapping, and table-splitting
capabilities, Entity Framework Core 2.0 is fully
supported.

Bugs Fixed

* EF Core: An invalid syntax error was generated when a new
property (defined as numeric, has a default value, and is
not a primary key) was added to an entity that already
contained a primary-key column with the AUTO_INCREMENT
attribute. This fix validates that the entity property
(column) is a primary key first before adding the
attribute. (Bug #28293927)

* EF Core: The implementation of some methods required to
scaffold an existing database were incomplete. (Bug
#27898343, Bug #90368)

* The Entity Framework Core implementation did not render
accented characters correctly on bases with different
UTF-8 encoding. Thanks to Kleber kleberksms for the
patch. (Bug #27818822, Bug #90316)

* The Microsoft.EntityFrameworkCore assembly (with EF Core
2.0) was not loaded and the absence generated an error
when the application project was built with any version
of .NET Framework. This fix ensures the following
support:

+ EF Core 1.1 with .NET Framework 4.5.2 only

+ EF Core 2.0 with .NET Framework 4.6.1 or later
(Bug #27815706, Bug #90306)

* Attempts to create a new foreign key from within an
application resulted in an exception when the key was
generated by a server in the MySQL 8.0 release series.
(Bug #27715069)

* A variable of type POINT when used properly within an
application targeting MySQL 8.0 generated an SQL syntax
error. (Bug #27715007)

* The case-sensitive lookup of field ordinals was
initialized using case-insensitive comparison logic. This
fix removes the original case-sensitive lookup. (Bug
#27285641, Bug #88950)

* The TreatTinyAsBoolean connection option was ignored when
the MySqlCommand.Prepare() method was called. (Bug
#27113566, Bug #88472)

* The MySql.Data.Types.MySqlGeometry constructor called
with an array of bytes representing an empty geometry
collection generated an ArgumentOutOfRangeException
exception, rather than creating the type as expected.
Thanks to Peet Whittaker for the patch. (Bug #26421346,
Bug #86974)

* Slow connections made to MySQL were improved by reducing
the frequency and scope of operating system details
required by the server to establish and maintain a
connection. (Bug #22580399, Bug #80030)

* All columns of type TINYINT(1) stopped returning the
expected Boolean value after the connector encountered a
NULL value in any column of this type. Thanks to David
Warner for the patch. (Bug #22101727, Bug #78917)

Changes in MySQL Shell 8.0.12 (2018-07-27, General Availability)

Functionality Added or Changed

* Important Change: An RPM package for installing ARM
64-bit (aarch64) binaries of MySQL Shell on Oracle Linux
7 is now available in the MySQL Yum Repository and for
direct download.
Known Limitation for this ARM release: You must enable
the Oracle Linux 7 Software Collections Repository
(ol7_software_collections) to install this package, and
must also adjust the libstdc++7 path. See Yum’s Platform
Specific Notes
(http://dev.mysql.com/doc/refman/8.0/en/linux-installatio
n-yum-repo.html#yum-install-platform-specifics) for
additional details.

* MySQL Shell now enables you to store user credentials in
an operating system specific secret store. You can then
enter a MySQL user’s password during connection and store
it for future connections. Currently the following secret
stores are supported:

+ MySQL login-path

+ MacOS keychain

+ Windows API
(Bug #23304789, Bug #81484)

* The way you access the online Shell help has been
standardized. Use the \help pattern command to search the
help. The scope of the command has been increased to
support retrieving help for the following categories:

+ Class and function help for the Admin API, X DevAPI
and Shell API. Previously, to retrieve help for API
objects, you had to create an instance of the object
and use the object.help() method.

+ SQL syntax help, provided that a global session
object exists.
Wildcards can now be used to search for help. A number of
additional bugs relating to incomplete help information
have also been fixed. (Bug #23255291, Bug #81277, Bug
#24963435, Bug #25732663, Bug #85481, Bug #25739522, Bug
#85511, Bug #25739664, Bug #85514, Bug #26393155, Bug
#86950, Bug #24943074, Bug #26429399, Bug #87037, Bug
#27870491, Bug #90455, Bug #27870503, Bug #90456, Bug
#27875150, Bug #90474, Bug #24948933, Bug #83527)

* The util.checkForServerUpgrade() operation has an
additional outputFormat parameter that you can specify
when running the utility. The utility can now generate
output in two formats:

+ TEXT format, which is the default. This option
provides output suitable for humans, as previously
returned by the utility.

+ JSON format. This option provides output suitable
for machines, which can be parsed and processed for
various further use cases.

* The cluster.removeInstance() command has been improved,
with the following changes:

+ A new interactive option has been added to enable or
disable interactive mode for the command. The output
displayed in interactive mode has been improved,
displaying more useful information.In interactive
mode, you are prompted to continue with the removal
of the instance (or not) in case it is not
reachable.

+ The operation now ensures that the instance is
removed from the metadata of all the cluster members
and itself. This only applies to ONLINE members.

+ A new global option dba.gtidWaitTimeout is available
to define the timeout to wait for transactions
(GTIDs) to be applied when required by AdminAPI
commands. If the timeout value defined by
dba.gtidWaitTimeout is reached when waiting for the
cluster transactions to be applied for
cluster.removeInstance() and force: false (or not
defined) then an error is issued and the operation
aborted. When force: true then the operation
continues and does not generate an error.
References: See also: Bug #27817894.

* When using the ipWhitelist to define which servers could
access the cluster, the internal user accounts were not
matching the whitelist. Now AdminAPI applies the same
filtering logic from ipWhitelist for the internal
administrative accounts.
References: See also: Bug #26140094, Bug #28165891.

* In order to be compliant with the X DevAPI specification,
the following changes have been made:

+ Collection.modify(condition).arrayDelete() and
Collection.modify(condition).merge() have been
deprecated.

+ Collection.find().limit(x).skip(y) has been renamed
to Collection.find().limit(x).offset(y).

+ Collection.find().limit(x).skip(y) has been
deprecated.

+ Collection.find().limit(x).offset(y) has been
implemented.

+ BaseResult.getAffectedItemsCount() has been
implemented.

+ BaseResult.getWarningCount() has been deprecated.

+ BaseResult.getWarningsCount() has been implemented.

+ Result.getAffectedItemCount() has been deprecated.

+ SqlResult.getAffectedRowCount() has been deprecated.

+ SqlResult.nextDataSet() has been renamed to
SqlResult.nextResult().

+ SqlResult.nextDataSet() has been deprecated.

+ SqlResult.nextResult() has been implemented.

Bugs Fixed

* The sample prompt theme files for MySQL Shell were
deployed to an incorrect location on the Windows
platform, in the root install folder. The files are now
correctly deployed in the \share\mysqlsh\prompt
sub-folder. (Bug #28188761)

* The cluster.forceQuorumUsingPartitionOf() operation sets
the group_replication_force_members variable on the
target instance to force a new group membership and
restore the quorum, but it did not reset the value of the
variable at the end of the process. Consequently, if
Group Replication later needed to be restarted on the
target instance it failed because the
group_replication_force_members variable was still set.
Now, the group_replication_force_members variable is
reset to an empty string at the end of the
cluster.forceQuorumUsingPartitionOf() operation. (Bug
#28064621)

* When upgrading from version 1.0.11 to version 8.0.11 of
MySQL Shell on Linux, the upgrade failed if the original
package was the community edition and the new package was
the commercial edition, or vice versa. Upgrading from one
edition to the other edition is now enabled. (Bug
#28037407)

* The util.checkForServerUpgrade() operation can now use
either an X Protocol connection or a classic MySQL
protocol connection. (Bug #28027707)

* The checkForServerUpgrade() operation to verify upgrade
prerequisites included an unnecessary check relating to
ZEROFILL and display length attributes in columns. The
check has now been removed. (Bug #27927641, Bug #90634)

* Some messages displayed by MySQL Shell were showing a
MySQL server version that does not exist. (Bug #27924694)

* For sessions using the classic MySQL protocol, if the
session_track_gtids system variable is set on the server
to capture and return GTIDs to the client, MySQL Shell
now displays the GTIDs for successfully committed
transactions. The returned GTID values are also now
recorded in tracing information. (Bug #27871148)

* When the defaultMode MySQL Shell configuration option had
been set with the –persist option, batch code execution
from a file was always attempted using the specified
default language, even if the file extension indicated a
different supported language. Now when a file is loaded
for batch processing using the –file or -f option, files
with the extensions .js, .py, and .sql are processed in
the appropriate language mode, regardless of the set
default language. (Bug #27861407)

* The methods provided in the shell.options configuration
interface to set and save persistent option values used
underscores in JavaScript as well as in Python mode. The
methods have now been changed to
shell.options.setPersist() and
shell.options.unsetPersist() in JavaScript to follow the
appropriate naming convention. (Bug #27861141)

* When executing a SQL script using MySQL Shell, delimiters
( such as the default semi-colon character) present in
multi-line comments caused execution to fail. Delimiters
are now ignored inside multi-line comments. (Bug
#27841719)

* MySQL Shell returned an error when querying timestamp
values that were zero, because a zero value for the month
or day in a date was not accepted. Zero timestamp values
can now be used without producing an error. (Bug
#27833822, Bug #90355)

* The shell.getSession() function returns a reference to
the session global object representing the already
established connection between MySQL Shell and a MySQL
server, known as a global session. MySQL Shell now
gracefully handles the situation where the function is
called when no global session has yet been established.
(Bug #27809310)

* It was possible to use AdminAPI operations on server
instances running an incompatible version of MySQL. (Bug
#27765769)

* The setting of the bind_address variable is no longer a
requirement. (Bug #27765484)

* When creating a cluster or adding an instance, if the
localAddress option is not specified, the port used for
group_replication_local_address is automatically assigned
with the value: port * 10 + 1. However, if the resulting
port determined by the previous rule was already in use
then a random port was generated and used. Now MySQL
Shell checks that the group_replication_local_address
port is available, and fails if it is not. (Bug
#27758041)

* The MySQL Shell application icon on Microsoft Windows was
not being displayed for the MySQL Shell 8.0 GA release,
due to an incorrect association introduced for the icon
during code refactoring. The icon is now displayed
correctly. (Bug #27746532)

* The dbPassword option is no longer valid in the options
dictionary of all AdminAPI commands. (Bug #27745106)

* The \status (\s) command in MySQL Shell now displays full
information about the version and build of the connected
MySQL server. (Bug #27740420)

* The check for reserved keywords carried out by the
util.checkForServerUpgrade() operation was updated to
match the list of reserved keywords for the MySQL 8.0 GA
release. (Bug #27724201)

* When handling escape sequences, MySQL Shell now
identifies and skips over SQL comments and string
literals within quotation marks. (Bug #27665229)

* Python’s mapping type has been added to MySQL Shell, so
that dictionary syntax can be used to interact with data
in Python mode. (Bug #27614110)

* When a file was redirected to standard input for
execution in MySQL Shell, on Unix, the first part of the
file was taken as being the password. The password prompt
now looks for user input first before resorting to
standard input. (Bug #27572380)

* It was possible to use the
dba.forceQuorumUsingPartition() operation on a cluster
which had not lost quorum. (Bug #27508698)

* The help message for
dba.rebootClusterFromCompleteOutage() operation was
incorrectly suggesting to use
dba.forceQuorumUsingPartition(). (Bug #27508627)

* If Ctrl + C was entered or an unexpected error occurred
at a password prompt in MySQL Shell, the terminal state
was not restored correctly afterwards. (Bug #27379834)

* The dba.rebootClusterFromCompleteOutage() operation was
creating a new user on the target instances, which could
lead to the existence of an increasing number of users.
The fix ensures that these users are not created by the
dba.rebootClusterFromCompleteOutage() operation. (Bug
#27344040)

* Now when you issue dba.getCluster() and retrieve a
cluster without quorum a warning is issued in addition to
the log message. (Bug #27148943)

* The memberSslMode option could be used with
cluster.addInstance() and cluster.rejoinInstance()
operations but if you specified a different value than
the one used at cluster creation an error was thrown. Now
set the SSL mode at the cluster level only, in other
words when issuing dba.createCluster(). The memberSslMode
option has been removed from cluster.addInstance() and
cluster.rejoinInstance(). (Bug #27062122)

* When you issued dba.configureLocalInsance() on an
instance, it configured the disabled_storage_engines
variable with the MyISAM, BLACKHOLE, FEDERATED, CSV, and
ARCHIVE storage engines to ensure that the storage engine
was set to InnoDB, as required by Group Replication. The
change to this option was not being reported correctly by
AdminAPI, and hence the required restart after changing
the disabled_storage_engines variable was not clear. This
change was deemed a recommendation, rather than a
requirement, hence dba.configureLocalInsance() no longer
configures disabled_storage_engines. (Bug #26754410)

* Creating a cluster using an account which was missing the
global grant option failed with an ambiguous error
message, even though dba.checkInstanceConfiguration() did
not return any errors. Now when you create a cluster, the
account being used to administer the cluster is checked
to ensure that it has the global grant option. (Bug
#25966235)

* MySQL Shell is able to automatically reconnect global
session when running in the interactive mode, but
AdminAPI methods lacked this feature. This resulted in
you having to reconnect manually. Now, the AdminAPI
methods which utilize the global session object have been
improved in order to detect an interrupted session and
trigger the reconnection mechanism. The Cluster object
uses its own internal session instance, which does not
support automatic reconnection. If connection to the
cluster is lost, you need to manually recreate the
Cluster object. (Bug #24702489)

* In the event of a whole cluster stopping unexpectedly,
upon reboot the memberSslMode was not preserved. In a
cluster where SSL had been disabled, upon issuing
dba.rebootClusterFromCompleteOutage() this could prevent
instances from rejoining the cluster. (Bug #90793, Bug
#27986413)
