Fix many -Wconversion warnings. Define my_thread_id as an unsigned type, to avoid mismatch with ulonglong. Change some parameters to this type. Use size_t in a few more places. Declare many flag constants as unsigned to avoid sign mismatch when shifting bits or applying the unary ~ operator. When applying the unary ~ operator to enum constants, explictly cast the result to an unsigned type, because enum constants can be treated as signed. In InnoDB, change the source code line number parameters from ulint to unsigned type. Also, make some InnoDB functions return a narrower type (unsigned or uint32_t instead of ulint; bool instead of ibool).

In this way, a single transaction will be used for updating the statistics of a whole table, even for partitioned tables. ha_innobase::commit_inplace_alter_table(): Drop statistics for all partitions when adding or dropping virtual columns, so that the statistics will be recalculated on the next handler::open(). This is a refactored version of Oracle Bug#22469660 fix.

MDEV-12698 innodb.innodb_stats_del_mark test failure In my merge of the MySQL fix for Oracle Bug#23333990 / WL#9513 I overlooked some subsequent revisions to the test, and I also failed to notice that the test is actually always failing. Oracle introduced the parameter innodb_stats_include_delete_marked but failed to consistently take it into account in FOREIGN KEY constraints that involve CASCADE or SET NULL. When innodb_stats_include_delete_marked=ON, obviously the purge of delete-marked records should update the statistics as well. One more omission was that statistics were never updated on ROLLBACK. We are fixing that as well, properly taking into account the parameter innodb_stats_include_delete_marked. dict_stats_analyze_index_level(): Simplify an expression. (Using the ternary operator with a constant operand is unnecessary obfuscation.) page_scan_method_t: Revert the change done by Oracle. Instead, examine srv_stats_include_delete_marked directly where it is needed. dict_stats_update_if_needed(): Renamed from row_update_statistics_if_needed(). row_update_for_mysql_using_upd_graph(): Assert that the table statistics are initialized, as guaranteed by ha_innobase::open(). Update the statistics in a consistent way, both for FOREIGN KEY triggers and for the main table. If FOREIGN KEY constraints exist, do not dereference a freed pointer, but cache the proper value of node->is_delete so that it matches prebuilt->table. row_purge_record_func(): Update statistics if innodb_stats_include_delete_marked=ON. row_undo_ins(): Update statistics (on ROLLBACK of a fresh INSERT). This is independent of the parameter; the record is not delete-marked. row_undo_mod(): Update statistics on the ROLLBACK of updating key columns, or (if innodb_stats_include_delete_marked=OFF) updating delete-marks. innodb.innodb_stats_persistent: Renamed and extended from innodb.innodb_stats_del_mark. Reduced the unnecessarily large dataset from 262,144 to 32 rows. Test both values of the configuration parameter innodb_stats_include_delete_marked. Test that purge is updating the statistics. innodb_fts.innodb_fts_multiple_index: Adjust the result. The test is performing a ROLLBACK of an INSERT, which now affects the statistics. include/wait_all_purged.inc: Moved from innodb.innodb_truncate_debug to its own file.

MDEV-14511 Use fewer transactions for updating InnoDB persistent statistics dict_stats_exec_sql(): Expect the caller to always provide a transaction. Remove some redundant assertions. The caller must hold dict_sys->mutex, but holding dict_operation_lock is only necessary for accessing data dictionary tables, which we are not accessing. dict_stats_save_index_stat(): Acquire dict_sys->mutex for invoking dict_stats_exec_sql(). dict_stats_save(), dict_stats_update_for_index(), dict_stats_update(), dict_stats_drop_index(), dict_stats_delete_from_table_stats(), dict_stats_delete_from_index_stats(), dict_stats_drop_table(), dict_stats_rename_in_table_stats(), dict_stats_rename_in_index_stats(), dict_stats_rename_table(): Use a single caller-provided transaction that is started and committed or rolled back by the caller. dict_stats_process_entry_from_recalc_pool(): Let the caller provide a transaction object. ha_innobase::open(): Pass a transaction to dict_stats_init(). ha_innobase::create(), ha_innobase::discard_or_import_tablespace(): Pass a transaction to dict_stats_update(). ha_innobase::rename_table(): Pass a transaction to dict_stats_rename_table(). We do not use the same transaction as the one that updated the data dictionary tables, because we already released the dict_operation_lock. (FIXME: there is a race condition; a lock wait on SYS_* tables could occur in another DDL transaction until the data dictionary transaction is committed.) ha_innobase::info_low(): Pass a transaction to dict_stats_update() when calculating persistent statistics. alter_stats_norebuild(), alter_stats_rebuild(): Update the persistent statistics as well. In this way, a single transaction will be used for updating the statistics of a whole table, even for partitioned tables. ha_innobase::commit_inplace_alter_table(): Drop statistics for all partitions when adding or dropping virtual columns, so that the statistics will be recalculated on the next handler::open(). This is a refactored version of Oracle Bug#22469660 fix. RecLock::add_to_waitq(), lock_table_enqueue_waiting(): Do not allow a lock wait to occur for updating statistics in a data dictionary transaction, such as DROP TABLE. Instead, return the previously unused error code DB_QUE_THR_SUSPENDED. row_merge_lock_table(), row_mysql_lock_table(): Remove dead code for handling DB_QUE_THR_SUSPENDED. row_drop_table_for_mysql(), row_truncate_table_for_mysql(): Drop the statistics as part of the data dictionary transaction. After TRUNCATE TABLE, the statistics will be recalculated on subsequent ha_innobase::open(), similar to how the logic after the above-mentioned Oracle Bug#22469660 fix in ha_innobase::commit_inplace_alter_table() works. btr_defragment_thread(): Use a single transaction object for updating defragmentation statistics. dict_stats_save_defrag_stats(), dict_stats_save_defrag_stats(), dict_stats_process_entry_from_defrag_pool(), dict_defrag_process_entries_from_defrag_pool(), dict_stats_save_defrag_summary(), dict_stats_save_defrag_stats(): Add a parameter for the transaction. dict_stats_empty_table(): Make public.

Merge 10.1 into 10.2 This only merges MDEV-12253, adapting it to MDEV-12602 which is already present in 10.2 but not yet in the 10.1 revision that is being merged. TODO: Error handling in crash recovery needs to be improved. If a page cannot be decrypted (or read), we should cleanly abort the startup. If innodb_force_recovery is specified, we should ignore the problematic page and apply redo log to other pages. Currently, the test encryption.innodb-redo-badkey randomly fails like this (the last messages are from cmake -DWITH_ASAN): 2017-05-05 10:19:40 140037071685504 [Note] InnoDB: Starting crash recovery from checkpoint LSN=1635994 2017-05-05 10:19:40 140037071685504 [ERROR] InnoDB: Missing MLOG_FILE_NAME or MLOG_FILE_DELETE before MLOG_CHECKPOINT for tablespace 1 2017-05-05 10:19:40 140037071685504 [ERROR] InnoDB: Plugin initialization aborted at srv0start.cc[2201] with error Data structure corruption 2017-05-05 10:19:41 140037071685504 [Note] InnoDB: Starting shutdown... i================================================================= ==5226==ERROR: AddressSanitizer: attempting free on address which was not malloc()-ed: 0x612000018588 in thread T0 #0 0x736750 in operator delete(void*) (/mariadb/server/build/sql/mysqld+0x736750) #1 0x1e4833f in LatchCounter::~LatchCounter() /mariadb/server/storage/innobase/include/sync0types.h:599:4 #2 0x1e480b8 in LatchMeta<LatchCounter>::~LatchMeta() /mariadb/server/storage/innobase/include/sync0types.h:786:17 #3 0x1e35509 in sync_latch_meta_destroy() /mariadb/server/storage/innobase/sync/sync0debug.cc:1622:3 #4 0x1e35314 in sync_check_close() /mariadb/server/storage/innobase/sync/sync0debug.cc:1839:2 #5 0x1dfdc18 in innodb_shutdown() /mariadb/server/storage/innobase/srv/srv0start.cc:2888:2 #6 0x197e5e6 in innobase_init(void*) /mariadb/server/storage/innobase/handler/ha_innodb.cc:4475:3

Merge InnoDB 5.7 from mysql-5.7.9. Contains also MDEV-10547: Test multi_update_innodb fails with InnoDB 5.7 The failure happened because 5.7 has changed the signature of the bool handler::primary_key_is_clustered() const virtual function ("const" was added). InnoDB was using the old signature which caused the function not to be used. MDEV-10550: Parallel replication lock waits/deadlock handling does not work with InnoDB 5.7 Fixed mutexing problem on lock_trx_handle_wait. Note that rpl_parallel and rpl_optimistic_parallel tests still fail. MDEV-10156 : Group commit tests fail on 10.2 InnoDB (branch bb-10.2-jan) Reason: incorrect merge MDEV-10550: Parallel replication can't sync with master in InnoDB 5.7 (branch bb-10.2-jan) Reason: incorrect merge
