Eugene Kosov	6c5c1f0b2f	MDEV-19231 make DB_SUCCESS equal to 0 It's a micro optimization. On most platforms CPUs has instructions to compare with 0 fast. DB_SUCCESS is the most popular outcome of functions and this patch optimized code like (err == DB_SUCCESS) BtrBulk::finish(): bogus assertion fixed fil_node_t::read_page0(): corrected usage of os_file_read() que_eval_sql(): bugus assertion removed. Apparently it checked that the field was assigned after having been zero-initialized at object creation. It turns out that the return type of os_file_read_func() was changed in mysql/mysql-server@98909cefbc37e54efc6452c7e95bccbf64ac9213 (MySQL 5.7) from ibool to dberr_t. The reviewer (if there was any) failed to point out that because of future merges, it could be a bad idea to change the return type of a function without changing the function name. This change was applied to MariaDB 10.2.2 in commit `2e814d4702` but the MariaDB-specific code was not fully adjusted accordingly, e.g. in fil_node_open_file(). Essentially, code like !os_file_read(...) became dead code in MariaDB and later in Mariabackup 10.2, and we could be dealing with an uninitialized buffer after a failed page read.	7 years ago
Marko Mäkelä	4b822111ef	MDEV-8139: Clean up the freeing of B-tree pages btr_page_free(): Renamed from btr_page_free_low(). If scrubbing is enabled, zero out the page with proper redo logging. Only pass ahi=true to fseg_free_page() if the page is actually indexed. fil_space_t::modify_check(): Renamed from fsp_space_modify_check(). fsp_init_file_page(): Define inline.	7 years ago
Marko Mäkelä	1b95118c5f	buf_page_get_gen(): Allow BUF_GET_IF_IN_POOL with a dummy page_size The page_size argument to buf_page_get_gen() only matters when the page is going to be loaded into the buffer pool. Allow callers to pass a dummy parameter when using BUF_GET_IF_IN_POOL (which would return NULL if the block is not in the buffer pool).	7 years ago
FaramosCZ	f5ee7fb31f	Fix a memory leak in ALTER TABLE Closes #965	7 years ago
Marko Mäkelä	0f90728bc0	MDEV-16809 Allow full redo logging for ALTER TABLE Introduce the configuration option innodb_log_optimize_ddl for controlling whether native index creation or table-rebuild in InnoDB should keep optimizing the redo log (and writing MLOG_INDEX_LOAD records to ensure that concurrent backup would fail). By default, we have innodb_log_optimize_ddl=ON, that is, the default behaviour that was introduced in MariaDB 10.2.2 (with the merge of InnoDB from MySQL 5.7) will be unchanged. BtrBulk::m_trx: Replaces m_trx_id. We must be able to check for KILL QUERY even if !m_flush_observer (innodb_log_optimize_ddl=OFF). page_cur_insert_rec_write_log(): Declare globally, so that this can be called from PageBulk::insert(). row_merge_insert_index_tuples(): Remove the unused parameter trx_id. row_merge_build_indexes(): Enable or disable redo logging based on the innodb_log_optimize_ddl parameter. PageBulk::init(), PageBulk::insert(), PageBulk::finish(): Write redo log records if needed. For ROW_FORMAT=COMPRESSED, redo log will be written in PageBulk::compress() unless we called m_mtr.set_log_mode(MTR_LOG_NO_REDO).	7 years ago

Marko Mäkelä	a0df2693a2	Remove an unused parameter btr_store_big_rec_extern_fields(): Remove the unused parameter 'upd' that was added in https://github.com/mysql/mysql-server/commit/ce0a1e85e24e48b8171f767b44330d and merged to MariaDB 10.2.2 in commit `2e814d4702`.	8 years ago
Marko Mäkelä	48192f963a	Add the parameter bool leaf to rec_get_offsets() This should affect debug builds only. Debug builds will check that the status bits of ROW_FORMAT!=REDUNDANT records match the is_leaf parameter. The only observable change to non-debug should be the addition of the is_leaf parameter to the function rec_copy_prefix_to_dtuple(), and the removal of some calls to update the adaptive hash index (it is only built for the leaf pages). This change should have been made in MySQL 5.0.3, instead of introducing the status flags in the ROW_FORMAT=COMPACT record header.	8 years ago
Marko Mäkelä	50faeda4d6	Remove trx_t::has_search_latch and simplify debug code When the btr_search_latch was split into an array of latches in MySQL 5.7.8 as part of the Oracle Bug#20985298 fix, the "caching" of the latch across storage engine API calls was removed, and the field trx->has_search_latch would only be set during a short time frame in the execution of row_search_mvcc(), which was formerly called row_search_for_mysql(). This means that the column INFORMATION_SCHEMA.INNODB_TRX.TRX_ADAPTIVE_HASH_LATCHED will always report 0. That column cannot be removed in MariaDB 10.2, but it can be removed in future releases. trx_t::has_search_latch: Remove. trx_assert_no_search_latch(): Remove. row_sel_try_search_shortcut_for_mysql(): Remove a redundant condition on trx->has_search_latch (it was always true). sync_check_iterate(): Make the parameter const. sync_check_functor_t: Make the operator() const, and remove result() and the virtual destructor. There is no need to have mutable state in the functors. sync_checker<bool>: Replaces dict_sync_check and btrsea_sync_check. sync_check: Replaces btrsea_sync_check. dict_sync_check: Instantiated from sync_checker. sync_allowed_latches: Use std::find() directly on the array. Remove the std::vector. TrxInInnoDB::enter(), TrxInInnoDB::exit(): Remove obviously redundant debug assertions on trx->in_depth, and use equality comparison against 0 because it could be more efficient on some architectures.	8 years ago
Jan Lindström	fec844aca8	Merge InnoDB 5.7 from mysql-5.7.14. Contains also: MDEV-10549 mysqld: sql/handler.cc:2692: int handler::ha_index_first(uchar*): Assertion `table_share->tmp_table != NO_TMP_TABLE \|\| m_lock_type != 2' failed. (branch bb-10.2-jan) Unlike MySQL, InnoDB still uses THR_LOCK in MariaDB MDEV-10548 Some of the debug sync waits do not work with InnoDB 5.7 (branch bb-10.2-jan) enable tests that were fixed in MDEV-10549 MDEV-10548 Some of the debug sync waits do not work with InnoDB 5.7 (branch bb-10.2-jan) fix main.innodb_mysql_sync - re-enable online alter for partitioned innodb tables	9 years ago
Jan Lindström	2e814d4702	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	9 years ago
