From ca9b46f71a55e53f85ae2f8e28f0d88126a44307 Mon Sep 17 00:00:00 2001 From: unknown Date: Sun, 23 Apr 2006 12:48:31 +0400 Subject: Applied innodb-5.1-ss475 snapshot. * Fix BUG#15650: "DELETE with LEFT JOIN crashes server with innodb_locks_unsafe_for binlog" * Fix BUG#17134: "Partitions: uncommitted changes are visible" * Fix BUG#17992: "Partitions: InnoDB, somehow rotten table after UPDATE" row0ins.c: MySQL's partitioned table code does not set preduilt->sql_stat_start right if it does an insert in the same statement after doing a search first in the same partition table. We now write trx id always to the buffer, not just when flag sql_stat_start is on. This will waste CPU time very sightly. * Fix BUG#18077: "InnoDB uses full explicit table locks in stored FUNCTION" * Fix BUG#18238: "When locks exhaust the buffer pool, InnoDB does not roll back the trx" * Fix BUG#18252" "Disk space leak in updates of InnoDB BLOB rows in 5.0 and 5.1" * Fix BUG#18283: "When InnoDB returns error 'lock table full', MySQL can write to binlog too much" * Fix BUG#18350: "Use consistent read in CREATE ... SELECT ... if innodb_locks_unsafe_for_binlog" * Fix BUG#18384: "InnoDB memory leak on duplicate key errors in 5.0 if row has many columns" * Fix BUG#18934: "InnoDB crashes when table uses column names like DB_ROW_ID" Refuse tables that use reserved column names. * InnoDB's SQL parser: - Add support for UNSIGNED types, EXIT keyword, quoted identifiers, user-function callbacks for processing results of FETCH statements, bound literals, DATA_VARCHAR for bound literals. - Allow bound literals of type non-INTEGER to be of length 0. - Add make_flex.sh and update lexer/parser generation documentation. - Add comment clarifying the difference between 'alias' and 'indirection' fields in sym_node_t. - Remove never reached duplicate code in pars_set_dfield_type(). - Rewrite pars_info datatypes and APIs, add a few helper functions. - Since the functions definitions in pars_info_t are accessed after pars_sql() returns in the query graph execution stage, we can't free pars_info_t in pars_sql(). Instead, make pars_sql() transfer ownership of pars_info_t to the created query graph, and make que_graph_free() free it if needed. - Allow access to system columns like DB_ROW_ID. * Use bound literals in row_truncate_table_for_mysql, row_drop_table_for_mysql, row_discard_tablespace_for_mysql, and row_rename_table_for_mysql. * Setting an isolation level of the transaction to read committed weakens the locks for this session similarly like the option innodb_locks_unsafe_for binlog. This patch removes alnost all gap locking (used in next-key locking) and makes MySQL to release the row locks on the rows which does not belong to result set. Additionally, nonlocking selects on INSERT INTO SELECT, UPDATE ... (SELECT ...), and CREATE ... SELECT ... use a nonlocking consistent read. If a binlog is used, then binlog format should be set to row based binloging to make the execution of the complex SQL statements. * Disable the statistic variables btr_search_n_hash_fail and n_hash_succ, n_hash_fail, n_patt_succ, and n_searches of btr_search_t in builds without #ifdef UNIV_SEARCH_PERF_STAT. * Make innodb.test faster. Group all consistent read test cases to a one test case and wait their lock timeout after all have been send to the server. Decrease amount of rows inserted in a certain test - this has no effect on the effectiveness of the test and reduces the running time by ~10 sec. Remove temporary work-arounds from innodb.result now that ALTER TABLE DROP FOREIGN KEY works once again. * Make innodb_unsafe_binlog.test faster. Grout all consistent read test cases to a one test case amd wait their lock timeout after all have been sent to the server. Remove unnecessary option --loose_innodb_lock_wait_timeout. * Print dictionary memory size in SHOW INNODB STATUS. * Fix memory leaks in row_create_table_for_mysql() in rare corner cases. * Remove code related to clustered tables. They were never implemented, and the implementation would be challenging with ROW_FORMAT=COMPACT. Remove the table types DICT_TABLE_CLUSTER_MEMBER and DICT_TABLE_CLUSTER and all related tests and functions. dict_table_t: Remove mix_id, mix_len, mix_id_len, mix_id_buf, and cluster_name. plan_t: Remove mixed_index. dict_create_sys_tables_tuple(): Set MIX_ID=0, MIX_LEN=0, CLUSTER_NAME=NULL when inserting into SYS_TABLES. dict_tree_check_search_tuple(): Enclose in #ifdef UNIV_DEBUG. * Move calling of thr_local_free() from trx_free_for_mysql() to innobase_close_connection(). mysql-test/r/innodb.result: Applied innodb-5.1-ss475 snapshot. mysql-test/r/innodb_unsafe_binlog.result: Applied innodb-5.1-ss475 snapshot. mysql-test/t/innodb-master.opt: Applied innodb-5.1-ss475 snapshot. mysql-test/t/innodb.test: Applied innodb-5.1-ss475 snapshot. mysql-test/t/innodb_unsafe_binlog-master.opt: Applied innodb-5.1-ss475 snapshot. mysql-test/t/innodb_unsafe_binlog.test: Applied innodb-5.1-ss475 snapshot. sql/ha_innodb.cc: Applied innodb-5.1-ss475 snapshot.
