Changes in MySQL 5.7.30:

JSON Notes

The rapidjson library included with MySQL has been upgraded to the GitHub \ 
snapshot of 16 January 2020. A fix for a compiler error encountered when \ 
building from the snapshot on Mac OS X has been added.

Packaging Notes

Binary packages that include curl rather than linking to the system curl library \ 
have been upgraded to use curl 7.69.0.

The bundled libedit library was upgraded to version 3.1.

Bugs Fixed

InnoDB: The row_upd_clust_rec_by_insert function, which marks a clustered index \ 
record as deleted and inserts an updated version of the record into the \ 
clustered index, passed an incorrect n_ext value (the total number of external \ 
fields) to lower level functions, causing an assertion failure.

InnoDB: An operation performed with the innodb_buffer_pool_evict debug variable \ 
set to uncompressed caused an assertion failure.

InnoDB: An add column operation caused an assertion failure. The failure was due \ 
to a dangling pointer.

InnoDB: Updating certain InnoDB system variables that take string values raised \ 
invalid read errors during Valgrind testing.

InnoDB: An insert statement on a table with a spatial index raised a record type \ 
mismatch assertion due to a tuple corruption.

InnoDB: A function that calculates undo log record size could calculate an \ 
incorrect length value in the case of a corrupted undo log record, resulting in \ 
a malloc failure. Assertion code was added to detect incorrect calculations.

Replication: While an SQL statement was in the process of being rewritten for \ 
the binary log so that sensitive information did not appear in plain text, if a \ 
SHOW PROCESSLIST statement was used to inspect the query, the query could become \ 
corrupted when it was written to the binary log, causing replication to stop. \ 
The process of rewriting the query is now kept private, and the query thread is \ 
updated only when rewriting is complete.

Replication: When a GRANT or REVOKE statement is only partially executed, an \ 
incident event is logged in the binary log, which makes the replication slave's \ 
applier thread stop so that the slave can be reconciled manually with the \ 
master. Previously, if a failed GRANT or REVOKE statement was the first \ 
statement executed in the session, no GTID was applied to the incident event \ 
(because the cache manager did not yet exist for the session), causing an error \ 
on the replication slave. Also, no incident event was logged in the situation \ 
where a GRANT statement created a user but then failed because the privileges \ 
had been specified incorrectly, again causing an error on the replication slave. \ 
Both these issues have now been fixed.

Replication: When a replication slave has a generated column that the master \ 
does not have in that table, with a secondary index on the generated column, the \ 
generated expression should be evaluated and the value stored by the storage \ 
engine in the secondary index. When row-based binary logging is in use, the \ 
replication slave assigns default values to any fields that are not in the \ 
master's definition of the table. In the case of a generated column, which does \ 
not have a default value, the slave was previously assigning a null or a zero \ 
value to the column. This value was then stored by the storage engine in the \ 
secondary index, causing both the table and the index to become corrupted. To \ 
fix this issue, generated columns in a table on a replication slave are now \ 
re-evaluated before the values are sent to the storage engine.

Replication: In the event of an unplanned disconnection of a replication slave \ 
from the master, the reference to the master's dump thread might not be removed \ 
from the list of registered slaves, in which case statements that accessed the \ 
list of slaves would fail. The issue has now been fixed.

Replication: With the settings binlog_format=MIXED, tx_isolation=READ-COMMITTED, \ 
and binlog_row_image=FULL, an INSERT ... SELECT query involving a transactional \ 
storage engine omitted any columns with a null value from the row image written \ 
to the binary log. This happened because when processing INSERT ... SELECT \ 
statements, the columns were marked for inserts before the binary logging format \ 
was selected. The issue has now been fixed.

The -libs-compat RPM package is now built with system zlib to avoid problems \ 
with unrestricted export of symbols in libmysqlclient.so.18.

The Event Scheduler had a memory leak.

Under certain circumstances, a memcached command could result in reading an \ 
uninitialized memory buffer, causing a failure.

Using ALTER USER to reset an account MAX_USER_CONNECTIONS value did not take \ 
effect until all current account connections terminated, if there were any.

A materialized subquery including a condition in which a column value was used \ 
as input to a nondeterministic function produced incorrect results.

CONCAT() and CONCAT_WS() could produce incorrect results in rare cases due to \ 
incorrect substring handling.

Scheduling of events could be disturbed by removing events.

Client programs could load authentication plugins from outside the plugin library.

The server did not handle correctly a UNION in which one of the queries \ 
contained a subquery that used ORDER BY.

A query with a WHERE clause whose predicate contained a numeric value in \ 
scientific notation was not handled correctly.

In addition, attempting to insert a particular integer specified as a string \ 
caused a server exit when the string-to-integer conversion was not successful.

Previously, mysqlpump read the [mysql_dump] and [client] groups from option \ 
files. mysqlpump now additionally reads the [mysqlpump] group. The [mysql_dump] \ 
group is still accepted but is deprecated.

A multi-table UPDATE statement which updated a table joined to a derived table \ 
that joined two other tables was not optimized properly as it had been in MySQL \ 
5.6, instead being treated as if STRAIGHT_JOIN had been used with the subquery \ 
creating the derived table.

Audit Log Notes

ANALYZE TABLE statements now produce read audit events.

Packaging Notes

Binary packages that include curl rather than linking to the system curl library \ 
have been upgraded to use curl 7.66.0.

Bugs Fixed

InnoDB: os_file_get_parent_dir warnings were encountered when compiling MySQL \ 
with GCC 9.2.0.

InnoDB: An internal function (btr_push_update_extern_fields()) used to fetch \ 
newly added externally stored fields and update them during a pessimistic update \ 
or when going back to a previous version of a record was no longer required. \ 
Newly added externally stored fields are updated by a different function. Also, \ 
the method used to determine the number of externally stored fields was \ 
corrected.

InnoDB: A comparison function found two records to be equal when attempting to \ 
merge non-leaf pages of a spatial index. The function was unable to handle this \ 
unexpected condition, which resulted in a long semaphore wait and an eventual \ 
assertion failure.

InnoDB: A tablespace import operation that failed due to the source and \ 
destination tables being defined with different DATA DIRECTORY clauses reported \ 
an insufficiently descriptive schema mismatch error. Moreover, if a .cfg file \ 
was not present, the same operation would raise an assertion failure. A more \ 
informative error message is now reported in both cases before the import \ 
operation is terminated due to the data directory mismatch.

InnoDB: Criteria used by the btr_cur_will_modify_tree() function, which detects \ 
whether a modifying record needs a modifying tree structure, was insufficient.

InnoDB: An ALTER TABLE ... DISCARD TABLESPACE operation caused a hang condition.

InnoDB: A code regression was addressed by prohibiting unnecessary implicit to \ 
explicit secondary index lock conversions for session temporary tables.

InnoDB: A tablespace import operation raised an assertion when the cursor was \ 
positioned on a corrupted page while purging delete-marked records. Instead of \ 
asserting when encountering a corrupted page, the import operation is now \ 
terminated and an error is reported.

Replication: When a member is joining or rejoining a replication group, if Group \ 
Replication detects an error in the distributed recovery process (during which \ 
the joining member receives state transfer from an existing online member), it \ 
automatically switches over to a new donor, and retries the state transfer. The \ 
number of times the joining member retries before giving up is set by the \ 
group_replication_recovery_retry_count system variable. The Performance Schema \ 
table replication_applier_status_by_worker displays the error that caused the \ 
last retry. Previously, this error was only shown if the group member was \ 
configured with parallel replication applier threads (as set by the \ 
slave_parallel_workers system variable). If the group member was configured with \ 
a single applier thread, the error was cleared after each retry by an internal \ 
RESET SLAVE operation, so it could not be viewed. This was also the case for the \ 
output of the SHOW SLAVE STATUS command whether there wer
e single or multiple applier threads. The RESET SLAVE operation is now no longer \ 
carried out after retrying distributed recovery, so the error that caused the \ 
last retry can always be viewed.

Replication: A memory leak could occur when a failed replication group member \ 
tried to rejoin a minority group and was disallowed from doing so.

Replication: If a replication slave was set up using a CHANGE MASTER TO \ 
statement that did not specify the master log file name and master log position, \ 
then shut down before START SLAVE was issued, then restarted with the option \ 
--relay-log-recovery set, replication did not start. This happened because the \ 
receiver thread had not been started before relay log recovery was attempted, so \ 
no log rotation event was available in the relay log to provide the master log \ 
file name and master log position. In this situation, the slave now skips relay \ 
log recovery and logs a warning, then proceeds to start replication.

Replication: When GTIDs are enabled on a replication master and slave, and the \ 
slave connects to the master with the MASTER_AUTO_POSITION=1 option set, the \ 
master must send the slave all the transactions that the slave has not already \ 
received, committed, or both. If any of the transactions that should be sent by \ 
the master have been already purged from the master's binary log, the master \ 
sends the error ER_MASTER_HAS_PURGED_REQUIRED_GTIDS (1789) to the slave, and \ 
replication does not start.

The message provided for the error ER_MASTER_HAS_PURGED_REQUIRED_GTIDS has been \ 
changed to provide advice on the correct action in this situation, which is for \ 
the slave to replicate the missing transactions from another source, or for the \ 
slave to be replaced by a new slave created from a more recent backup. The \ 
message advises that the master's binary log expiration period can be revised to \ 
avoid the situation in future. In addition, the master now identifies the GTIDs \ 
of the purged transactions and supplies them in its error log in the warning \ 
message ER_FOUND_MISSING_GTIDS (11809), so that you do not need to calculate the \ 
missing GTIDs manually.

macOS: On macOS, configuring MySQL with -DWITH_SSL=system caused mysql_config \ 
output to incorrectly include internal CMake names for the static SSL libraries.

There could be a mismatch between the version of OpenSSL used to build the \ 
server and the version used for other parts of MySQL such as libraries or \ 
plugins. This could cause certain features not to work, such as the LDAP \ 
authentication plugins. Now the same version of OpenSSL is used for building \ 
everything.

Docker packages were missing the LDAP authentication plugins.

The original table name for a field in a derived table was not always displayed \ 
correctly.

MySQL Installer was unable to uninstall MySQL 5.7 on Windows Server 2012.

With multiple sessions executing concurrent INSERT ... ON DUPLICATE KEY UPDATE \ 
statements into a table with an AUTO_INCREMENT column but not specifying the \ 
AUTO_INCREMENT value, inserts could fail with a unique index violation.

With lower_case_table_names=2, SHOW TABLES could fail to display tables with \ 
uppercase names.

With keyring_encrypted_file_password set on the command line at server startup, \ 
the password value could be visible to system utilities.

With a LOCK TABLES statement in effect, a metadata change for the locked table \ 
could cause Performance Schema or SHOW queries for session variables to hang in \ 
the opening_tables state.

A SELECT using a WHERE condition of the form A AND (B OR C [OR ...]) resulting \ 
in an impossible range led to an unplanned exit of the server.

For JSON-format audit logging, the id field now may contain values larger than \ 
65535. Previously, with heaving logging activity, more than 65536 queries per \ 
second could be executed, exceeding the 16 bits permitted for id values.

An incomplete connection packet could cause clients not to properly initialize \ 
the authentication plugin name.

Client programs that used the libmysqlclient C client library could exit upon \ 
receipt of an OK packet containing malformed session-tracking information.

Under certain conditions, enabling the read_only or super_read_only system \ 
variable did not block concurrent DDL statements executed by users without the \ 
SUPER privilege.

mysqlpump exits rather than dumping databases that contain an invalid view, by \ 
design, but it also failed if an invalid view existed but was not in any of the \ 
databases to be dumped.
