MDEV-31098 InnoDB Recovery doesn't display encryption message when no encryption configuration passed - InnoDB fails to report the error when encryption configuration wasn't passed. This patch addresses the issue by adding the error while loading the tablespace and deferring the tablespace creation.

In commit 5ea5291d @sanja-byelkin for unknown reason switched the file mode for 3 Galera tzinfo related test files from 644 -> 755. This exists only from branch 10.6 onward: $ git checkout 10.5 $ find mysql-test -executable -name *.test -or -executable -name *.result (no results) $ git checkout 10.6 $ find mysql-test -executable -name *.test -or -executable -name *.result mysql-test/suite/galera/t/mysql_tzmysql-test/suite/galera/t/mysql_tzinfo_to_sql.test mysql-test/suite/galera/t/mariadb_tzinfo_to_sql.test mysql-test/suite/galera/r/mariadb_tzinfo_to_sql.resultinfo_to_sql.test mysql-test/suite/galera/t/mariadb_tzinfo_to_sql.test mysql-test/suite/galera/r/mariadb_tzinfo_to_sql.result No test file nor test result file should be executable, so run chmod -x on them.

Use an std::atomic_flag to track thread creation in progress. This is mainly a cleanup, the effect of this change was not measureable in my tests.

Add threadpool functionality to restrict concurrency during "batch" periods (where tasks are added in rapid succession). This will throttle thread creation more agressively than usual, while keeping performance at least on-par. One of these cases is bufferpool load, where async read IOs are executed without any throttling. There can be as much as 650K read IOs for loading 10GB buffer pool. Another one is recovery, where "fake read" IOs are executed. Why there are more threads than we expect? Worker threads are not be recognized as idle, until they return to the standby list, and to return to that list, they need to acquire mutex currently held in the submit_task(). In those cases, submit_task() has no worker to wake, and would create threads until default concurrency level (2*ncpus) is satisfied. Only after that throttling would happen.

The problem was that we did not handle errors properly in JOIN::get_best_combination. In case an early error, JOIN->join_tab would contain unintialized values, which would cause errors on cleanup(). The error in question was reported earlier, but not noticed until later. One cause of this is that most of the sql_select.cc code just checks thd->fatal_error and not thd->is_error(). Fixed by changing of checks of fatal_error to is_error().

Raise notes if indexes cannot be used: - in case of data type or collation mismatch (diferent error messages). - in case if a table field was replaced to something else (e.g. Item_func_conv_charset) during a condition rewrite. Added option to write warnings and notes to the slow query log for slow queries. New variables added/changed: - note_verbosity, with is a set of the following options: basic - All old notes unusable_keys - Print warnings about keys that cannot be used for select, delete or update. explain - Print unusable_keys warnings for EXPLAIN querys. The default is 'basic,explain'. This means that for old installations the only notable new behavior is that one will get notes about unusable keys when one does an EXPLAIN for a query. One can turn all of all notes by either setting note_verbosity to "" or setting sql_notes=0. - log_slow_verbosity has a new option 'warnings'. If this is set then warnings and notes generated are printed in the slow query log (up to log_slow_max_warnings times per statement). - log_slow_max_warnings - Max number of warnings written to slow query log. Other things: - One can now use =ALL for any 'set' variable to set all options at once. For example using "note_verbosity=ALL" in a config file or "SET @@note_verbosity=ALL' in SQL. - mysqldump will in the future use @@note_verbosity=""' instead of @sql_notes=0 to disable notes. - Added "enum class Data_type_compatibility" and changing the return type of all Field::can_optimize*() methods from "bool" to this new data type. Reviewer & Co-author: Alexander Barkov <bar@mariadb.com> - The code that prints out the notes comes mainly from Alexander

The warning is given in case of table not found or if there is a lock timeout. The warning is needed as in case of a lock timeout then the persistent table stats are going to be wrong.

Example of what causes the problem: T1: ANALYZE TABLE starts to collect statistics T2: ALTER TABLE starts by deleting statistics for all changed fields, then creates a temp table and copies data to it. T1: ANALYZE ends and writes to the statistics tables. T2: ALTER TABLE renames temp table in place of the old table. Now the statistics from analyze matches the old deleted tables. Fixed by waiting to delete old statistics until ALTER TABLE is the only one using the old table and ensure that rename of columns can handle swapping of column names. rename_columns_in_stat_table() (former rename_column_in_stat_tables()) now takes a list of columns to rename. It uses the following algorithm to update column_stats to be able to handle circular renames - While there are columns to be renamed and it is the first loop or last rename loop did change something. - Loop over all columns to be renamed - Change column name in column_stat - If fail because of duplicate key - If this is first change attempt for this column - Change column name to a temporary column name - If there was a conflicting row, replace it with the current row. else - Remove entry from column list - Loop over all remaining columns in the list - Remove the conflicting row - Change column from temporary name to final name in column_stat Other things: - Don't flush tables for every operation. Only flush when all updates are done. - Rename of columns was not handled in case of ALGORITHM=copy (old bug). - Fixed that we do not collect statistics for hidden hash columns used by UNIQUE constraint on long values. - Fixed that we do not collect statistics for blob columns referred by generated virtual columns. This was achieved by storing the fields for which we want to have statistics in table->has_value_set instead of in table->read_set. - Rename of indexes was not handled for persistent statistics. - This is now handled similar as rename of columns. Renamed columns are now stored in 'rename_stat_indexes' and handled in Alter_info::delete_statistics() together with drooped indexes. - ALTER TABLE .. ADD INDEX may instead of creating a new index rename an existing generated foreign key index. This was not reflected in the index_stats table because this was handled in mysql_prepare_create_table instead instead of in the mysql_alter() code. Fixed by adding a call in mysql_prepare_create_table() to drop the changed index. I also had to change the code that 'marked the index' to be ignored with code that would not destroy the original index name. Reviewer: Sergei Petrunia <sergey@mariadb.com>

In `pseudo_slave_mode=1` aka "psedo-slave" mode any prepared XA transaction disconnects from the user session, as if the user connection drops. The xid of such transaction remains in the server, and should the prepared transaction be read-only, it is marked. The marking makes sure that the following termination of the read-only transaction ends up with ER_XA_RBROLLBACK. This did not take place actually for `pseudo_slave_mode=1` read-only. Fixed with checking the read-only status of a prepared transaction at time it disconnects from the `pseudo_slave_mode=1` session, to mark its xid when that's the case.

MDEV-30217 : Assertion `mode_ == m_local || transaction_.is_streaming()' failed in int wsrep::client_state::bf_abort(wsrep::seqno) Problem was that brute force (BF) thread requested conflicting lock and was trying to kill victim transaction, but this victim was also brute force thread. However, this victim was not actually holding conflicting lock, instead both brute force transaction and victim transaction were had insert intention locks. We should not kill brute force victim transaction if requesting lock does not need to wait. Signed-off-by: Julius Goryavsky <julius.goryavsky@mariadb.com>

is_file_on_ssd() is more expensive than it should be. It caches the results by volume name, but still calls GetVolumePathName() every time, which, as procmon shows, opens multiple directories in filesystem hierarchy (db directory, datadir, and all ancestors) The fix is to cache SSD status by volume serial ID, which is cheap to retrieve with GetFileInformationByHandleEx()

Follow-up to fix issue with access to probably not-initialized mutex/cond_var Constructor of the class st_debug_sync_globals was changed to initialize the data members dsp_hits, dsp_executed, dsp_max_active with zero. Formerly, these data members were filled with zeroes by C-runtime since the variable debug_sync_global was declared as static and according with C rules the static variable initialized with zero bytes. By the same reason, the data members debug_sync_global->ds_mutex debug_sync_global->ds_cond were initialized by zeros before the patch for MDEV-31871. After this patch the memory for the synch primitives debug_sync_global->ds_mutex and debug_sync_global->ds_cond are initialized explicitly by calling the functions mysql_mutex_init/mysql_cond_init so access to these synch primitives should be done only after such initialization be completed. Guarded access to these synch primitives has been added to the function debug_sync_end_thread() that is called on clean up since that was single problem place detected by MSAN. Theoretically problem places located in the function debug_sync_execute were not protected with similar check since it is not obvious that the variables debug_sync_global->ds_mutex and debug_sync_global->ds_cond could be not initilialized for use cases where the function debug_sync_execute() is called. It is required additional study to conclude whether it does need or not.

mariadb-install crashes on start when the static variable debug_sync_global of the class st_debug_sync_globals is initialized by constructor. Definition of the class st_debug_sync_globals has a data member of the type Hash_set whose implementation depends on thread-specific data associated with the key THD_KEY_mysys. This dependency results from constructor of the class Hash_set that runs my_hash_init2() which in turn invokes my_malloc. The thread-specific data value associated with the key THD_KEY_mysys is used by the function sf_malloc to get id of the current thread. The key THD_KEY_mysys is defined as static variable at my_thr_init.c initialized with the value -1. Proper initialization of the key THD_KEY_mysys is done with the library call pthread_key_create but it happens at the my_init() that called much later after the first time the THD_KEY_mysys() has been invoked. In according with Single Unix Specification, the effect of calling pthread_setspecific() or pthread_getspecific() with a key value not obtained from pthread_key_create() is undefined. That is the reason why mariadb-install crashes on MacOS. To fix the issue, the static variable debug_sync_global is converted to a pointer to the class st_debug_sync_globals and its instantiation is done explicitly at the function debug_sync_init() that is called at right time. This is the follow-up patch to the commits 8885225d f6ecadfe where was introduced a statically instantiated object debug_sync_global of the structure st_debug_sync_globals and the key THR_KEY_mysys for this thread-specific data was initialized with the value -1.

trx_t::set_skip_lock_inheritance() must be invoked at the very beginning of lock_release_on_prepare(). Currently trx_t::set_skip_lock_inheritance() is invoked at the end of lock_release_on_prepare() when lock_sys and trx are released, and there can be a case when locks on prepare are released, but "not inherit gap locks" bit has not yet been set, and page split inherits lock to supremum. Also reset supremum bit and rebuild waiting queue when XA is prepared. Reviewed by: Marko Mäkelä

MDEV-29731 Assertion failure when HAVING in a correlated subquery references columns in the outer query When resolving a column from the HAVING clause, a new Item_field object may be created inside Item_ref::fix_fields(). But the object is created with an empty name resolution context, which then leads to debug assertion failure during Item_field::fix_fields(). The solution is to pass the correct name resolution context when creating the Item_field object. Reviewer: Oleksandr Byelkin (sanja@mariadb.com)
