mysql57: updated to 5.7.36
Changes in MySQL 5.7.36
Security Notes
Bugs Fixed
Security Notes
The linked OpenSSL library for MySQL Server has been updated to version 1.1.1l. Issues fixed in the new OpenSSL version are described at https://www.openssl.org/news/cl111.txt and and http://www.openssl.org/news/vulnerabilities.html.
Bugs Fixed
Incompatible Change: For all SELECT statements on a view, the query digest was based on the view definition. As a result, different queries had the same digest and aggregated together in the Performance Schema table events_statements_summary_by_digest, so statistics in that table were not usable for distinguishing distinct SELECT statements.
The query digest for each SELECT statement on a view now is based on the SELECT, not the view definition. This enables distinguishing distinct SELECT statements in the events_statements_summary_by_digest table. However, tools that use query digests may need some adjustment to account for this change. For example, MySQL Enterprise Firewall and query rewrite plugins rely on query digests and existing rules for them that are associated with views may need to be updated.
InnoDB: With undo log truncation enabled (innodb_undo_log_truncate=ON), it was possible for a deadlock and eventual failure to occur when an undo log truncate operation was initiated after a version upgrade from MySQL 5.6 to MySQL 5.7.34 or earlier. A patch introduced in MySQL 5.7.35
[Note] InnoDB: Found duplicate reference rseg: 33 space: 1 page: 3
[Note] InnoDB: Reset pre-5.7.2 rseg: 1 after duplicate is found.
If pre-5.7.2 rollback segment slots have no undo data to purge, a message similar to the following is emitted:
[Note] InnoDB: Successfully reset 32 pre-5.7.2 rseg slots.
If undo data is found in pre-5.7.2 rollback segment slots, a message similar to the following is emitted recommending a slow shutdown and restart:
[Note] InnoDB: pre-5.7.2 rseg: 2 holds data to be purged.
History length: 1. Recommend slow shutdown with innodb_fast_shutdown=0 and restart
InnoDB: Truncation of an undo tablespace during use by an active transaction raised an assertion failure. The transaction was prematurely marked as complete, permitting the truncation operation.
InnoDB: Deleting or updating a row from a parent table initiated a cascading SET NULL operation on the child table that set a virtual column value to NULL. The virtual column value should have been derived from the base column value.
Thanks to Yin Peng at Tencent for the contribution.
InnoDB: The InnoDB recovery process did not recognize that page compression had been applied to data that was being recovered, causing the tablespace data file to increase in size during the redo log apply phase, which could lead to a recovery failure for systems approaching a disk-full state.
Replication: The error messages issued by MySQL Replication when GTIDs required for auto-positioning have been purged could be incorrectly assigned or scrambled in some situations.
Replication: The contents of the gtid_executed and gtid_purged GTID sets were not persisted after restoring a dump taken using mysqldump. The dump file sequence has now been changed so that the mysql schema (which contains the mysql.gtid_executed table) is not dropped after the gtid_purged GTID set is written. A new option --skip-mysql-schema is added for mysqldump which lets you choose not to drop the mysql schema at all.
JSON: Conversion of JSON values to text caused linear growth of the destination string, resulting in an unnecessarily high number of reallocations. Now this process uses exponential growth instead, to reduce the number of allocations required.
This fix originally appeared in MySQL 8.0 and was backported to MySQL 5.7 by Annirudh Prasad, whom we thank for the contribution.
Concurrent insert operations on multiple tables with full-text indexes caused a large number of full-text index synchronization requests, resulting in an out of memory condition.
When a query uses a temporary table for aggregation, the group by item is used as a unique constraint on the temporary table: If the item value is already present, the row is updated; otherwise, a new row is inserted into the temporary table. If the item has a result field or reference item, it it evaluated twice, once to check whether the result exists in the temporary table and, if not, again while constructing the row to be inserted. When the group by item was nondeterministic, the result value used to check for existence differed from that with which an insert was attempted, causing the insert to be rejected if the value already existed in the table.
We fix this by using the hash of any nondeterministic items as the unique constraint, so that the hash is evaluated once only.
Quote handling was improved for the SHOW GRANTS statement.

mysql57: updated to 5.7.28
Changes in MySQL 5.7.28
Configuration Notes
It is now possible to compile MySQL 5.7 using OpenSSL 1.1.1, enabling compilation support for MySQL 5.7 against OpenSSL even when OpenSSL 1.0.2 reaches End of Life status at the end of 2019.
All MySQL 5.7 builds now use OpenSSL. MySQL no longer supports using yaSSL as the SSL library, and source distributions no longer include yaSSL.
The WITH_SSL CMake option no longer permits bundled (use yaSSL) as a valid value, and the default option value has changed from bundled to system (use the version of OpenSSL installed on the host system).
sys Schema Notes
The sys.schema_unused_indexes view now filters out unique indexes.
The sys.ps_is_consumer_enabled() function now produces an error rather than returning NULL if the argument is an unknown non-NULL consumer name.
Previously, sys schema sources were maintained in a separate Git repository. sys schema sources now are included with and maintained within MySQL source distributions (under scripts/sys_schema).
The sys.version view is deprecated and will be removed in a future MySQL version. Affected applications should be adjusted to use an alternative instead. For example, use the VERSION() function to retrieve the MySQL server version.
Bugs Fixed
InnoDB: An ALTER TABLE ... ENCRYPTION = 'Y' operation on a MyISAM table failed to raise an error indicating that the storage engine does not support encryption. The INPLACE algorithm did not check encryption support before updating metadata in the .frm file. To address this issue, an encryption support flag was added. The ALTER TABLE ... ENCRYPTION = 'Y' operation now checks the flag and reports an error if the storage engine does not support encryption.
InnoDB: Delete marked rows were able to acquire an external read lock before a partial rollback was completed. The external read lock prevented conversion of an implicit lock to an explicit lock during the partial rollback, causing an assertion failure.
InnoDB: A long running ALTER TABLE ... ADD INDEX operation with concurrent inserts caused semaphore waits.
Replication: A deadlock involving three threads could occur if a START SLAVE statement was issued to start the SQL thread on a slave while the SQL thread was still in the process of being stopped, and a request for the slave status was made at the same time. The issue has now been fixed by releasing a lock earlier while the SQL thread is being stopped.
Replication: A locking issue in the WAIT_FOR_EXECUTED_GTID_SET() function could cause the server to hang in certain circumstances. The issue has now been corrected.
Replication: On a multi-threaded slave with GTIDs in use and MASTER_AUTO_POSITION set to ON, following an unexpected halt the slave would attempt relay log recovery, which failed if relay logs had been lost, preventing replication from starting. However, this step was unnecessary as GTID auto-positioning can be used to restore any missing transactions. In a recovery situation, the slave now checks first whether MASTER_AUTO_POSITION is set to ON, and if it is, skips relay log recovery.
When generating C source from SQL scripts, Some utf8-encoded characters were split across lines. Thanks to Przemysław Skibiński for the patch.
For Solaris, mysqld.cc contained a prototype for memcntl() that is no longer needed. The prototype has been removed.
For Solaris, -DWITH_SSL=system did not work when compiling with GCC.
MySQL builds configured with -DWITHOUT_SERVER=1 failed.
For the keyring_aws plugin, some valid region values for the keyring_aws_region system variable were rejected.
For debug builds, an assertion could be raised during UNION queries when computing the combined data type of a GEOMETRY column and SELECT * FROM (SELECT NULL).
For authentication using an LDAP authentication plugin, if the user DN portion was empty and group mapping was configured, authentication assigned an incorrect user DN and skipped the user search.
mysqlpump produced an error when run against a server older than MySQL 5.7.
A possible integer overflow due to unsigned integer type casting could lead to later buffer overflow due to arbitrary size memory allocation.
Attempted use of a freed object during MeCab plugin initialization caused a segmentation fault.
For MySQL installed using RPM packages, an initialization script that tested server connectivity misbehaved if the client account authenticated using an LDAP authentication plugin.
Improper locking during storage engine initialization could cause a server exit.
On a GTID-enabled server, concurrent execution of DROP USER and a prepared statement that accessed a view could deadlock.
A query with a WHERE clause whose predicate contained a numeric value in scientific notation was not handled correctly.
VS2019 produced compilation errors with debug compilation selected due to use of the /ZI flag. Now /Z7 is used instead.
The client library could dereference a null pointer while fetching result set metadata from the server.
In READ UNCOMMITTED isolation level, a segmentation fault occurred under heavy load from memcached clients. An externally stored BLOB column that was being updated by one transaction was read by another transaction as having a NULL value and a non-zero data length.
Arguments for the TIMESTAMPADD() function could be reversed for prepared statements.
With the thread_pool plugin enabled, the sys.processlist and sys.session views displayed a thread name rather than the actual user name.
The delete_latency column in the sys.schema_index_statistics view incorrectly referred to the SUM_TIMER_INSERT column of the Performance Schema table_io_waits_summary_by_index_usage table rather than the SUM_TIMER_DELETE column.
In output from the sys.diagnostics() procedure, the latency column for the user_summary_by_file_io_type view was incorrectly displayed in raw picoseconds rather than as a formatted value.
MySQL Enterprise Encryption functions could apply Diffie-Hellman (DH) methods to non-DH keys, resulting in unpredictable results or server exit.
Password masking was incomplete for SHOW PROCESSLIST and some INFORMATION_SCHEMA and Performance Schema tables.
The -DWITH_EXAMPLE_STORAGE_ENGINE=1 CMake option was ignored but should not have been. If -DWITH_EXAMPLE_STORAGE_ENGINE=0 is given, the EXAMPLE storage engine is built as a plugin.

mysql57: updated to 5.7.30
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.

Arguments for the TIMESTAMPADD() function could be reversed for prepared statements.
With the thread_pool plugin enabled, the sys.processlist and sys.session views displayed a thread name rather than the actual user name.
The delete_latency column in the sys.schema_index_statistics view incorrectly referred to the SUM_TIMER_INSERT column of the Performance Schema table_io_waits_summary_by_index_usage table rather than the SUM_TIMER_DELETE column.
In output from the sys.diagnostics() procedure, the latency column for the user_summary_by_file_io_type view was incorrectly displayed in raw picoseconds rather than as a formatted value.
MySQL Enterprise Encryption functions could apply Diffie-Hellman (DH) methods to non-DH keys, resulting in unpredictable results or server exit.
Password masking was incomplete for SHOW PROCESSLIST and some INFORMATION_SCHEMA and Performance Schema tables.
The -DWITH_EXAMPLE_STORAGE_ENGINE=1 CMake option was ignored but should not have been. If -DWITH_EXAMPLE_STORAGE_ENGINE=0 is given, the EXAMPLE storage engine is built as a plugin.

mysql57: update to 5.7.20
Changes in MySQL 5.7.20:
Audit Log Notes
Event-matching filter rules for the audit_log plugin now support an abort element, which can be used to prevent qualifying events from executing. For more information, see Audit Log Filtering. This capability can be used, for example, to augment the capabilities of MySQL Enterprise Firewall, which blocks SQL statements on a per-user basis, by writing audit filtering rules that match statements and block them based on characteristics of the statements themselves.
Deprecation and Removal Notes
Previously, the --transaction-isolation and --transaction-read-only server startup options corresponded to the tx_isolation and tx_read_only system variables. For better name correspondence between startup option and system variable names, transaction_isolation and transaction_read_only have been created as aliases for tx_isolation and tx_read_only. The tx_isolation and tx_read_only variables are now deprecated and will be removed in MySQL 8.0. Applications should be adjusted to use transaction_isolation and transaction_read_only instead.
The query cache is now deprecated and is removed in MySQL 8.0. Deprecation includes these items:
* The FLUSH QUERY CACHE and RESET QUERY CACHE statements.
* The SQL_CACHE and SQL_NO_CACHE SELECT modifiers.
* These system variables: have_query_cache, ndb_cache_check_time, query_cache_limit, query_cache_min_res_unit, query_cache_size, query_cache_type, query_cache_wlock_invalidate.
* These status variables: Qcache_free_blocks, Qcache_free_memory, Qcache_hits, Qcache_inserts, Qcache_lowmem_prunes, Qcache_not_cached, Qcache_queries_in_cache, Qcache_total_blocks.
The mysql client by default strips comments in statements sent to the server, and this behavior is controlled using --skip-comments (strip comments), and --comments (preserve comments).
Comment stripping is now deprecated. This feature and the options to control it will be removed in a future MySQL release.
These syntax constructs for table and column references are now deprecated and will be removed in a future version of MySQL. Instances of these constructs should be changed to remove the leading period.
* .col_name
* .tbl_name
* .tbl_name.col_name
Security Notes
Certificates automatically generated by mysqld and mysql_ssl_rsa_setup now use X509 v3 rather than v1.
The keyring_okv plugin now supports password-protecting the key file used for secure connections. See Using the keyring_okv KMIP Plugin.

mysql57: updated to 5.7.28
Changes in MySQL 5.7.28
Configuration Notes
It is now possible to compile MySQL 5.7 using OpenSSL 1.1.1, enabling compilation support for MySQL 5.7 against OpenSSL even when OpenSSL 1.0.2 reaches End of Life status at the end of 2019.
All MySQL 5.7 builds now use OpenSSL. MySQL no longer supports using yaSSL as the SSL library, and source distributions no longer include yaSSL.
The WITH_SSL CMake option no longer permits bundled (use yaSSL) as a valid value, and the default option value has changed from bundled to system (use the version of OpenSSL installed on the host system).
sys Schema Notes
The sys.schema_unused_indexes view now filters out unique indexes.
The sys.ps_is_consumer_enabled() function now produces an error rather than returning NULL if the argument is an unknown non-NULL consumer name.
Previously, sys schema sources were maintained in a separate Git repository. sys schema sources now are included with and maintained within MySQL source distributions (under scripts/sys_schema).
The sys.version view is deprecated and will be removed in a future MySQL version. Affected applications should be adjusted to use an alternative instead. For example, use the VERSION() function to retrieve the MySQL server version.
Bugs Fixed
InnoDB: An ALTER TABLE ... ENCRYPTION = 'Y' operation on a MyISAM table failed to raise an error indicating that the storage engine does not support encryption. The INPLACE algorithm did not check encryption support before updating metadata in the .frm file. To address this issue, an encryption support flag was added. The ALTER TABLE ... ENCRYPTION = 'Y' operation now checks the flag and reports an error if the storage engine does not support encryption.
InnoDB: Delete marked rows were able to acquire an external read lock before a partial rollback was completed. The external read lock prevented conversion of an implicit lock to an explicit lock during the partial rollback, causing an assertion failure.
InnoDB: A long running ALTER TABLE ... ADD INDEX operation with concurrent inserts caused semaphore waits.
Replication: A deadlock involving three threads could occur if a START SLAVE statement was issued to start the SQL thread on a slave while the SQL thread was still in the process of being stopped, and a request for the slave status was made at the same time. The issue has now been fixed by releasing a lock earlier while the SQL thread is being stopped.
Replication: A locking issue in the WAIT_FOR_EXECUTED_GTID_SET() function could cause the server to hang in certain circumstances. The issue has now been corrected.
Replication: On a multi-threaded slave with GTIDs in use and MASTER_AUTO_POSITION set to ON, following an unexpected halt the slave would attempt relay log recovery, which failed if relay logs had been lost, preventing replication from starting. However, this step was unnecessary as GTID auto-positioning can be used to restore any missing transactions. In a recovery situation, the slave now checks first whether MASTER_AUTO_POSITION is set to ON, and if it is, skips relay log recovery.
When generating C source from SQL scripts, Some utf8-encoded characters were split across lines. Thanks to Przemysław Skibiński for the patch.
For Solaris, mysqld.cc contained a prototype for memcntl() that is no longer needed. The prototype has been removed.
For Solaris, -DWITH_SSL=system did not work when compiling with GCC.
MySQL builds configured with -DWITHOUT_SERVER=1 failed.
For the keyring_aws plugin, some valid region values for the keyring_aws_region system variable were rejected.
For debug builds, an assertion could be raised during UNION queries when computing the combined data type of a GEOMETRY column and SELECT * FROM (SELECT NULL).
For authentication using an LDAP authentication plugin, if the user DN portion was empty and group mapping was configured, authentication assigned an incorrect user DN and skipped the user search.
mysqlpump produced an error when run against a server older than MySQL 5.7.
A possible integer overflow due to unsigned integer type casting could lead to later buffer overflow due to arbitrary size memory allocation.
Attempted use of a freed object during MeCab plugin initialization caused a segmentation fault.
For MySQL installed using RPM packages, an initialization script that tested server connectivity misbehaved if the client account authenticated using an LDAP authentication plugin.
Improper locking during storage engine initialization could cause a server exit.
On a GTID-enabled server, concurrent execution of DROP USER and a prepared statement that accessed a view could deadlock.
A query with a WHERE clause whose predicate contained a numeric value in scientific notation was not handled correctly.
VS2019 produced compilation errors with debug compilation selected due to use of the /ZI flag. Now /Z7 is used instead.
The client library could dereference a null pointer while fetching result set metadata from the server.
In READ UNCOMMITTED isolation level, a segmentation fault occurred under heavy load from memcached clients. An externally stored BLOB column that was being updated by one transaction was read by another transaction as having a NULL value and a non-zero data length.
Arguments for the TIMESTAMPADD() function could be reversed for prepared statements.
With the thread_pool plugin enabled, the sys.processlist and sys.session views displayed a thread name rather than the actual user name.
The delete_latency column in the sys.schema_index_statistics view incorrectly referred to the SUM_TIMER_INSERT column of the Performance Schema table_io_waits_summary_by_index_usage table rather than the SUM_TIMER_DELETE column.
In output from the sys.diagnostics() procedure, the latency column for the user_summary_by_file_io_type view was incorrectly displayed in raw picoseconds rather than as a formatted value.
MySQL Enterprise Encryption functions could apply Diffie-Hellman (DH) methods to non-DH keys, resulting in unpredictable results or server exit.
Password masking was incomplete for SHOW PROCESSLIST and some INFORMATION_SCHEMA and Performance Schema tables.
The -DWITH_EXAMPLE_STORAGE_ENGINE=1 CMake option was ignored but should not have been. If -DWITH_EXAMPLE_STORAGE_ENGINE=0 is given, the EXAMPLE storage engine is built as a plugin.

mysql57: updated to 5.7.34
Changes in MySQL 5.7.34 (2021-04-20, General Availability)
Configuration Notes
The CMAKE_BUILD_TYPE CMake option now supports a Release build type, which is like the RelWithDebInfo build type but omits debugging information to reduce the build size.
Packaging Notes
The bundled libedit library was upgraded to version 20190324-3.1.
Binary packages that include curl rather than linking to the system curl library have been upgraded to use curl 7.74.0.
Security Notes
The linked OpenSSL library for MySQL Server has been updated to version 1.1.1k. Issues fixed in the new OpenSSL version are described at https://www.openssl.org/news/cl111.txt and https://www.openssl.org/news/vulnerabilities.html.
Functionality Added or Changed
Microsoft Windows: The named_pipe_full_access_group system variable now defaults to an empty string (''), making named pipe connections secure. Previously, '*everyone*' was the default value. A valid Windows local group name may be substituted.
Bugs Fixed
InnoDB: The introduction of sharded rw_lock_stats counters in MySQL 5.7 caused a regression in CPU cache efficiency. To address this issue in MySQL 5.7, the sharding method was changed. For optimal performance, the rw_lock_stats counter is removed in MySQL 8.0.
InnoDB: A delete operation on a parent table that initiated a cascading update on a child table with an indexed virtual column and indexed foreign key constraint column caused a virtual column corruption.
InnoDB: An adaptive hash index (AHI) latch was held in shared mode by a thread truncating a large table, causing mutex waits for other threads. The AHI latch was not required and has been removed.
InnoDB: The open and close sequence for table share instances (m_share objects) and dictionary table instances was modified to prevent accessing old m_share objects that could point to stale dictionary indexes.
Thanks to Yuxiang Jiang for the contribution.
InnoDB: An online ALTER TABLE operation failed with an “Incorrect key file for table” error due to an unnecessary encryption status check that was performed when reading online DDL row logs.
Replication: If all previous binary log files were purged at startup because their retention period had expired, the new binary log file contained an empty Previous_gtids event, which could cause errors in replication. The order of initialization has now been changed so that previous binary log files are only purged after the previous GTID set has been written to the new binary log file that is created at startup.
Replication: An assertion was raised in debug builds relating to lost GTIDs if binary log files were removed at startup because their retention period had expired.
Replication: A deadlock could occur if the binary log file was rotated while system variables were being updated and read by different clients.
Replication: The output of a SHOW PROCESSLIST statement for a replica’s SQL thread sometimes showed the last query as currently being applied when the replica was actually caught up.
A query string was displayed before it had been rewritten.
For builds compiled using the libedit library, if the mysql client was invoked with the --default-character-set=utf8 option, libedit rejected input of multibyte characters.
On Windows, large result sets could cause the mysql client to exit unexpectedly.
Improper locking on an internal queue could cause mysqlpump to exit unexpectedly.
It is now possible to use START REPLICA SQL_THREAD and STOP REPLICA SQL_THREAD statements for the group_replication_applier channel when Group Replication is stopped. This enables an operator to apply any remaining unapplied transactions on a server that left the group, without having to rejoin the server to the group.
When the mysql client was used in batch mode, its parser could be confused by USE followed by DROP DATABASE when the USE database name was quoted.
While optimizing the ORDER BY clause of a subquery there was a possibility of cleaning up a subquery tree referenced in the outer SELECT, which could lead to a premature exit.
A malformed name in the mysql.func system table could cause unexpected server behavior.
Sessions could disable their own auditing.
Mishandling of stored program local variables could lead to unexpected server behavior.
Uninstalling a plugin could affect subsequent execution of prepared statements.

mysql57: updated to 5.7.24
Changes in MySQL 5.7.24
Deprecation and Removal Notes
* InnoDB; Partitioning: Support for placing table partitions in shared tablespaces is deprecated and will be removed in a future version of MySQL. Shared tablespaces include the system tablespace and general tablespaces. For information about identifying partitions in shared tablespaces and moving them to file-per-table tablespaces, see Preparing Your Installation for Upgrade.
* InnoDB: Support for TABLESPACE = innodb_file_per_table and TABLESPACE = innodb_temporary clauses with CREATE TEMPORARY TABLE is deprecated and will be removed in a future MySQL version.
Functionality Added or Changed
Replication: Use the group_replication_exit_state_action option to configure how Group Replication behaves when a member leaves the group involuntarily, for example when it is expelled from the group due to an unstable network connection. When group_replication_exit_state_action is set to ABORT_SERVER, upon exiting the group unintentionally, the instance shuts MySQL down, and when group_replication_exit_state_action is set to READ_ONLY the instance sets MySQL to super read only mode instead and its state is set to ERROR.
Previously, file I/O performed in the I/O cache in the mysys library was not instrumented, affecting in particular file I/O statistics reported by the Performance Schema about the binary log index file. Now, this I/O is instrumented and Performance Schema statistics are accurate. Thanks to Yura Sorokin for the contribution.
The zlib library version bundled with MySQL was raised from version 1.2.3 to version 1.2.11. MySQL implements compression with the help of the zlib library.
The zlib compressBound() function in zlib 1.2.11 returns a slightly higher estimate of the buffer size required to compress a given length of bytes than it did in zlib version 1.2.3. The compressBound() function is called by InnoDB functions that determine the maximum row size permitted when creating compressed InnoDB tables or inserting rows into compressed InnoDB tables. As a result, CREATE TABLE ... ROW_FORMAT=COMPRESSED or INSERT operations with row sizes very close to the maximum row size that were successful in earlier releases could now fail.
Bugs Fixed
* InnoDB: An ALTER TABLE operation that added a primary key produced a segmentation fault.
* InnoDB: A query that scanned the primary key of a table did not return the expected result.
* InnoDB: A query interruption during a lock wait caused an error.
* InnoDB: An index record was not found when updating a secondary index defined on a generated column.
* InnoDB: The update log applied as part of an online ALTER TABLE operation did not take into account the computed value of the generated column in the old row while updating the secondary index.
* InnoDB: An unsupported DDL operation involving a foreign key constraint raised an assertion.
* InnoDB: An attempted foreign key check on a discarded table caused a segmentation fault.
* InnoDB: An assertion was raised during an OPTIMIZE TABLE operation.
* InnoDB: A foreign key constraint name was duplicated during a rename table operation, causing a failure during later query execution.
* InnoDB: In a function called before the execution of a statement in a stored procedure, a read and write operation on trx->lock.start_stmt was not protected by a mutex.
* InnoDB: An error occurred during a DDL operation due to a mismatch in a REDUNDANT row format calculation that determines the length of the online log.
* InnoDB: The location of the Innodb Merge Temp File that reported by the wait/io/file/innodb/innodb_temp_file Performance Schema instrument was incorrect.
* Partitioning: When a CREATE TABLE ... PARTITION BY ... statement failed due to an invalid partition definition, the server did not remove any partition files which might have been created prior to encountering the invalid PARTITION clause.
* Partitioning: It was possible to perform FLUSH TABLES FOR EXPORT on a partitioned table created with innodb_file_per_table=1 after discarding its tablespace. Attempting to do so now raises ER_TABLESPACE_DISCARDED.
* Replication: When the binlog_group_commit_sync_delay system variable is set to a wait time to delay synchronization of transactions to disk, and the binlog_group_commit_sync_no_delay_count system variable is also set to a number of transactions, the MySQL server exits the wait procedure if the specified number of transactions is reached before the specified wait time is reached. The server manages this process by checking on the transaction count after a delta of one tenth of the time specified by binlog_group_commit_sync_delay has elapsed, then subtracting that interval from the remaining wait time.

Security Notes
* Security Fix: The linked OpenSSL library for the MySQL Commercial Server has been updated to version 1.0.2l. Issues fixed in the new OpenSSL version are described at http://www.openssl.org/news/vulnerabilities.html.
This change does not affect the Oracle-produced MySQL Community build of MySQL Server, which uses the yaSSL library instead.
Platform-Specific Notes
* Linux: The generic Linux build for MySQL 5.6 is now built on Oracle Linux 6 using glibc 2.12. Systems that use the build need to have glibc 2.12 or later installed on them.
Functionality Added or Changed
* For Windows, MSI installer packages now include a check for the required Visual Studio redistributable package, and produce a message asking the user to install it if it is missing.
* The mysql client now supports a --binary-as-hex option that causes display of binary data using hexadecimal notation (0xvalue). Thanks to Daniël van Eeden for the patch.
* mysqlaccess now looks for its configuration file only in the SYSCONFDIR directory and /etc.
Bugs Fixed
* InnoDB: The server allocated memory unnecessarily for an operation that rebuilt the table.
* InnoDB: When using an index merge optimizer switch, a SELECT COUNT(*) operation sometimes returned 0. Partitioning code incorrectly performed a memcpy instead of a column copy of columns read by the index, causing the wrong records to be copied.
* Replication: A USE statement that followed a SET GTID_NEXT statement sometimes had no effect.
* Replication: If the binary log on a master server was rotated and a full disk condition occurred on the partition where the binary log file was being stored, the server could stop unexpectedly. The fix adds a check for the existence of the binary log when the dump thread switches to next binary log file. If the binary log is disabled, all binary logs up to the current active log are transmitted to slave and an error is returned to the receiver thread.
* Replication: If a relay log index file named relay log files that did not exist, RESET SLAVE ALL sometimes did not fully clean up properly.
* Replication: mysqlbinlog, if invoked with the --raw option, does not flush the output file until the process terminates. But if also invoked with the --stop-never option, the process never terminates, thus nothing is ever written to the output file. Now the output is flushed after each event.
* Replication: A memory leak in mysqlbinlog was fixed. The leak happened when processing fake rotate events, or when using --raw and the destination log file could not be created. The leak only occurred when processing events from a remote server. Thanks to Laurynas Biveinis for his contribution to fixing this bug.
* Replication: Multi-threaded slaves could not be configured with small queue sizes using slave_pending_jobs_size_max if they ever needed to process transactions larger than that size. Any packet larger than slave_pending_jobs_size_max was rejected with the error ER_MTS_EVENT_BIGGER_PENDING_JOBS_SIZE_MAX, even if the packet was smaller than the limit set by slave_max_allowed_packet.
* With this fix, slave_pending_jobs_size_max becomes a soft limit rather than a hard limit. If the size of a packet exceeds slave_pending_jobs_size_max but is less than slave_max_allowed_packet, the transaction is held until all the slave workers have empty queues, and then processed. All subsequent transactions are held until the large transaction has been completed. The queue size for slave workers can therefore be limited while still allowing occasional larger transactions.
* mysqldump could write database names in USE statements incorrectly.
* If the mysql_stmt_close() C API function was called, it freed memory that later could be accessed if mysql_stmt_error(), mysql_stmt_errno(), or mysql_stmt_sqlstate() was called. To obtain error information after a call to mysql_stmt_close(), call mysql_error(), mysql_errno(), or mysql_sqlstate() instead.
* Queries could be cached incorrectly, leading to incorrect query results, under these circumstances: InnoDB table; rows are being inserted but have not yet been committed; a query uses the table as a base table in a derived table; the optimizer chooses to materialize the derived table.
* Man pages for a few utilities were missing from Debian/Ubuntu packages.
* The field-t unit test failed to run with AddressSanitizer enabled. Thanks to Laurynas Biveinis for the patch.
* Debian client packages were missing information about conflicts with native packages.
* The Perl path in #! lines at the beginning of Perl scripts has been adjusted to /usr/local/bin/perl for FreeBSD 11.
* The server exited abnormally attempting to access invalid memory.
* A race condition could occur for CREATE TABLE statements with DATA DIRECTORY or INDEX DIRECTORY clauses.
* MySQL compilation in different directories produced different builds to leakage of absolute paths into debug information and __FILE__.
* mysqld_failed to start the server if the --datadir option was specified with a relative path name.
* With read_only enabled, creation of non-TEMPORARY tables by non-SUPER users was permitted under certain conditions.
*Certain stored functions, if used in a query WHERE clause, could be handled using Index Condition Pushdown (which should not happen), resulting in a server exit.
* On x86 machines, the uint3korr() macro read 4 bytes of data instead of the intended 3 bytes.
* An assertion was raised during a fetch operation by the memcached plugin.
* Queries that contained UNION in a subquery and GROUP BY could return incorrect results.
* LOAD XML INFILE performance became noticeably slower when the XML file being read contained a great many spaces, such as those introduced by indenting or pretty-printing. Now all leading whitespace is trimmed from each such value before reading it into memory.

Changes in MySQL 5.7.28
Configuration Notes
It is now possible to compile MySQL 5.7 using OpenSSL 1.1.1, enabling compilation support for MySQL 5.7 against OpenSSL even when OpenSSL 1.0.2 reaches End of Life status at the end of 2019.
All MySQL 5.7 builds now use OpenSSL. MySQL no longer supports using yaSSL as the SSL library, and source distributions no longer include yaSSL.
The WITH_SSL CMake option no longer permits bundled (use yaSSL) as a valid value, and the default option value has changed from bundled to system (use the version of OpenSSL installed on the host system).
sys Schema Notes
The sys.schema_unused_indexes view now filters out unique indexes.
The sys.ps_is_consumer_enabled() function now produces an error rather than returning NULL if the argument is an unknown non-NULL consumer name.
Previously, sys schema sources were maintained in a separate Git repository. sys schema sources now are included with and maintained within MySQL source distributions (under scripts/sys_schema).
The sys.version view is deprecated and will be removed in a future MySQL version. Affected applications should be adjusted to use an alternative instead. For example, use the VERSION() function to retrieve the MySQL server version.

Improper locking during storage engine initialization could cause a server exit.
On a GTID-enabled server, concurrent execution of DROP USER and a prepared statement that accessed a view could deadlock.
A query with a WHERE clause whose predicate contained a numeric value in scientific notation was not handled correctly.
VS2019 produced compilation errors with debug compilation selected due to use of the /ZI flag. Now /Z7 is used instead.
The client library could dereference a null pointer while fetching result set metadata from the server.
In READ UNCOMMITTED isolation level, a segmentation fault occurred under heavy load from memcached clients. An externally stored BLOB column that was being updated by one transaction was read by another transaction as having a NULL value and a non-zero data length.
Arguments for the TIMESTAMPADD() function could be reversed for prepared statements.
With the thread_pool plugin enabled, the sys.processlist and sys.session views displayed a thread name rather than the actual user name.
The delete_latency column in the sys.schema_index_statistics view incorrectly referred to the SUM_TIMER_INSERT column of the Performance Schema table_io_waits_summary_by_index_usage table rather than the SUM_TIMER_DELETE column.
In output from the sys.diagnostics() procedure, the latency column for the user_summary_by_file_io_type view was incorrectly displayed in raw picoseconds rather than as a formatted value.
MySQL Enterprise Encryption functions could apply Diffie-Hellman (DH) methods to non-DH keys, resulting in unpredictable results or server exit.
Password masking was incomplete for SHOW PROCESSLIST and some INFORMATION_SCHEMA and Performance Schema tables.
The -DWITH_EXAMPLE_STORAGE_ENGINE=1 CMake option was ignored but should not have been. If -DWITH_EXAMPLE_STORAGE_ENGINE=0 is given, the EXAMPLE storage engine is built as a plugin.

mysql57: updated to 5.7.35
Changes in MySQL 5.7.35 (2021-07-20, General Availability)
Audit Log Notes
Deprecation and Removal Notes
Packaging Notes
Bugs Fixed
Audit Log Notes
For MySQL Enterprise Audit, the new audit_log_format_unix_timestamp system variable enables inclusion of a time field in each audit record. The field value is an integer that represents the UNIX timestamp value indicating the date and time when the audit event was generated. The time field is supported only for JSON-format log files.
Deprecation and Removal Notes
The TLSv1 and TLSv1.1 connection protocols now are deprecated and support for them is subject to removal in a future MySQL version. (For background, refer to the IETF memo Deprecating TLSv1.0 and TLSv1.1.) It is recommended that connections be made using the more-secure TLSv1.2 and TLSv1.3 protocols. TLSv1.3 requires that both the MySQL server and the client application be compiled with OpenSSL 1.1.1 or higher.
On the server side, this deprecation has the following effects:
If the tls_version system variable is assigned a value containing a deprecated TLS protocol during server startup, the server writes a warning for each deprecated protocol to the error log.
If a client successfully connects using a deprecated TLS protocol, the server writes a warning to the error log.
On the client side, the deprecation has no visible effect. Clients do not issue a warning if configured to permit a deprecated TLS protocol. This includes:
Client programs that support a --tls-version option for specifying TLS protocols for connections to the MySQL server.
Statements that enable replicas to specify TLS protocols for connections to the source server. (CHANGE MASTER TO has a MASTER_TLS_VERSION option.)
Packaging Notes
Binary packages that include curl rather than linking to the system curl library have been upgraded to use curl 7.77.0.
The bundled lz4 library was upgraded to version 1.9.3.
Bugs Fixed
InnoDB: A deadlock between a user thread and purge thread involving a undo log page and rollback segment page occurred after an undo tablespace truncate operation was initiated. The deadlock caused a long semaphore wait and an eventual failure.
InnoDB: An integer underflow issue was addressed in the InnoDB mecached plugin sources.
InnoDB: An index with a key prefix length greater than 767 bytes was permitted on a table defined with the REDUNDANT row format, exceeding the index key prefix length limit for that row format. The ALTER TABLE operation that added the index validated the index key prefix length for the row format defined by the innodb_default_row_format variable instead of the actual row format of the table. The fix ensures that index key prefix length is validated for the correct row format.
InnoDB: An online buffer pool resizing operation freed the previous buffer pool page hash, conflicting with a concurrent buffer pool lookup that required the previous page hash.
InnoDB: Numerous system temporary table pages at the tail of the buffer pool flush list caused a performance degradation. The flush_list_mutex was held while the flush list scan traversed over system temporary table pages. The flush list scan now excludes system temporary table pages.
InnoDB: A binary log rotation deadlock occurred on a system using statement-based replication where there was high number of concurrent update operations and low innodb_thread_concurrency setting.
Replication: When the system variable replication_optimize_for_static_plugin_config was set, the plugins for Group Replication and semi-synchronous replication could not be uninstalled cleanly on server shutdown.
Replication: A deadlock could occur when START GROUP_REPLICATION and STOP GROUP_REPLICATION statements were issued at the same time that a view change was taking place for the group.
Replication: A deadlock could occur if a STOP GROUP_REPLICATION statement was issued when a replication channel on a group member was attempting to commit a transaction. The server now rolls back the transaction immediately if it cannot acquire the relevant lock, rather than waiting for the lock and the commit to complete and causing the deadlock.
Replication: On a multithreaded replica, the reference to the active event was sometimes managed incorrectly when retrying a transaction.
Replication: Replica servers now check and validate the transaction ID part of a GTID before applying and committing the transaction associated with it.
Replication: Replication could stop on a multithreaded replica if a unique secondary key was omitted from the writeset hashes used to compute transaction dependencies, leading to errors when executing the transactions on the multithreaded replica. Write set hashes now always include unique secondary keys even if they are not included in the read set and write set.
JSON: Passing NULL to a stored procedure expecting a JSON parameter led to an assertion failure in debug builds.
Replication could fail if a DML statement was executed immediately after an XA transaction was rejected or forced to rollback due to a deadlock.
The mysql_change_user() C API function did not properly parse the COM_CHANGE_USER packet, which could result in silent failure to process optional query attributes that may have been supplied prior to the mysql_change_user() call. Thanks for René Cannaò for the contribution.
Repreparation of a prepared statement at the beginning of an implicit transaction could cause an ER_GTID_NEXT_TYPE_UNDEFINED_GROUP error.
An out-of-memory error occurred when loading large amounts of data into tables with full-text search indexes. Not all of the memory allocated to the full-text search cache was accounted for when inserting data into the full-text search auxiliary tables.
A secondary index over a virtual column became corrupted when the index was built online.
For UPDATE statements, we fix this as follows: If the virtual column value of the index record is set to NULL, then we generate this value from the cluster index record.
Boolean system variables could be assigned a negative value.

mysql57: updated to 5.7.34
Changes in MySQL 5.7.34 (2021-04-20, General Availability)
Configuration Notes
The CMAKE_BUILD_TYPE CMake option now supports a Release build type, which is like the RelWithDebInfo build type but omits debugging information to reduce the build size.
Packaging Notes
The bundled libedit library was upgraded to version 20190324-3.1.
Binary packages that include curl rather than linking to the system curl library have been upgraded to use curl 7.74.0.
Security Notes
The linked OpenSSL library for MySQL Server has been updated to version 1.1.1k. Issues fixed in the new OpenSSL version are described at https://www.openssl.org/news/cl111.txt and https://www.openssl.org/news/vulnerabilities.html.
Functionality Added or Changed
Microsoft Windows: The named_pipe_full_access_group system variable now defaults to an empty string (''), making named pipe connections secure. Previously, '*everyone*' was the default value. A valid Windows local group name may be substituted.
Bugs Fixed
InnoDB: The introduction of sharded rw_lock_stats counters in MySQL 5.7 caused a regression in CPU cache efficiency. To address this issue in MySQL 5.7, the sharding method was changed. For optimal performance, the rw_lock_stats counter is removed in MySQL 8.0.
InnoDB: A delete operation on a parent table that initiated a cascading update on a child table with an indexed virtual column and indexed foreign key constraint column caused a virtual column corruption.
InnoDB: An adaptive hash index (AHI) latch was held in shared mode by a thread truncating a large table, causing mutex waits for other threads. The AHI latch was not required and has been removed.
InnoDB: The open and close sequence for table share instances (m_share objects) and dictionary table instances was modified to prevent accessing old m_share objects that could point to stale dictionary indexes.
Thanks to Yuxiang Jiang for the contribution.
InnoDB: An online ALTER TABLE operation failed with an “Incorrect key file for table” error due to an unnecessary encryption status check that was performed when reading online DDL row logs.
Replication: If all previous binary log files were purged at startup because their retention period had expired, the new binary log file contained an empty Previous_gtids event, which could cause errors in replication. The order of initialization has now been changed so that previous binary log files are only purged after the previous GTID set has been written to the new binary log file that is created at startup.
Replication: An assertion was raised in debug builds relating to lost GTIDs if binary log files were removed at startup because their retention period had expired.
Replication: A deadlock could occur if the binary log file was rotated while system variables were being updated and read by different clients.
Replication: The output of a SHOW PROCESSLIST statement for a replica’s SQL thread sometimes showed the last query as currently being applied when the replica was actually caught up.
A query string was displayed before it had been rewritten.
For builds compiled using the libedit library, if the mysql client was invoked with the --default-character-set=utf8 option, libedit rejected input of multibyte characters.
On Windows, large result sets could cause the mysql client to exit unexpectedly.
Improper locking on an internal queue could cause mysqlpump to exit unexpectedly.
It is now possible to use START REPLICA SQL_THREAD and STOP REPLICA SQL_THREAD statements for the group_replication_applier channel when Group Replication is stopped. This enables an operator to apply any remaining unapplied transactions on a server that left the group, without having to rejoin the server to the group.
When the mysql client was used in batch mode, its parser could be confused by USE followed by DROP DATABASE when the USE database name was quoted.
While optimizing the ORDER BY clause of a subquery there was a possibility of cleaning up a subquery tree referenced in the outer SELECT, which could lead to a premature exit.
A malformed name in the mysql.func system table could cause unexpected server behavior.
Sessions could disable their own auditing.
Mishandling of stored program local variables could lead to unexpected server behavior.
Uninstalling a plugin could affect subsequent execution of prepared statements.
