Satya B	2bfc0136ac	Applying InnoDB snapshot 5.1-ss6242, part 7. Fixes BUG#49032 1. BUG#49032 - auto_increment field does not initialize to last value in InnoDB Storage Engine 2. Fix whitespace issues and fix tests and make read float/double arg const Detailed revision comments: r6231 \| sunny \| 2009-11-25 10:26:27 +0200 (Wed, 25 Nov 2009) \| 7 lines branches/5.1: Fix BUG#49032 - auto_increment field does not initialize to last value in InnoDB Storage Engine. We use the appropriate function to read the column value for non-integer autoinc column types, namely float and double. rb://208.

Timothy Smith	1a01d6a93b	Cherry-pick some changes from innodb-5.1-ss2479 snapshot. Includes fixes for Bug#36600 and Bug#36793: Bug #36600 SHOW STATUS takes a lot of CPU in buf_get_latched_pages_number Fix by removing the Innodb_buffer_pool_pages_latched variable from SHOW STATUS output in non-UNIV_DEBUG compilation. Bug #36793 rpl_innodb_bug28430 fails on Solaris This is a back port from branches/zip. This code has been tested on a big-endian machine too.	18 years ago
tsmith@ramayana.hindu.god	eb65479127	Apply snapshot innodb-5.1-ss1989 Fixes the following bugs: Bug #30706: SQL thread on slave is allowed to block client queries when slave load is high Add (innodb\|innobase\|srv)_replication_delay MySQL config parameter. Bug #30888: Innodb table + stored procedure + row deletion = server crash While adding code for the low level read of the AUTOINC value from the index, the case for MEDIUM ints which are 3 bytes was missed triggering an assertion. Bug #30907: Regression: "--innodb_autoinc_lock_mode=0" (off) not same as older releases We don't rely on *first_value to be 0 when checking whether get_auto_increment() has been invoked for the first time in a multi-row INSERT. We instead use trx_t::n_autoinc_rows. Initialize trx::n_autoinc_rows inside ha_innobase::start_stmt() too. Bug #31444: "InnoDB: Error: MySQL is freeing a thd" in innodb_mysql.test ha_innobase::external_lock(): Update prebuilt->mysql_has_locked and trx->n_mysql_tables_in_use only after row_lock_table_for_mysql() returns DB_SUCCESS. A timeout on LOCK TABLES would lead to an inconsistent state, which would cause trx_free() to print a warning. Bug #31494: innodb + 5.1 + read committed crash, assertion Set an error code when a deadlock occurs in semi-consistent read.	18 years ago
aivanov@mysql.com	d33b523271	Applied innodb-5.1-ss269 snapshot. Fixed BUGS: #3300: "UPDATE statement with no index column in where condition locks all rows" Implement semi-consistent read to reduce lock conflicts at the cost of breaking serializability. ha_innobase::unlock_row(): reset the "did semi consistent read" flag ha_innobase::was_semi_consistent_read(), ha_innobase::try_semi_consistent_read(): new methods row_prebuilt_t, row_create_prebuilt(): add field row_read_type for keeping track of semi-consistent reads row_vers_build_for_semi_consistent_read(), row_sel_build_committed_vers_for_mysql(): new functions row_search_for_mysql(): implement semi-consistent reads #9802: "Foreign key checks disallow alter table". Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #13778: "If FOREIGN_KEY_CHECKS=0, one can create inconsistent FOREIGN KEYs". When FOREIGN_KEY_CHECKS=0 we still need to check that datatypes between foreign key references are compatible. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" Note that buf_block_t::index should be protected by btr_search_latch or an s-latch or x-latch on the index page. btr_search_drop_page_hash_index(): Read block->index while holding btr_search_latch and use the cached value in the loop. Remove some redundant assertions. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces. When there are tens of thousands of file spaces, flushing all files in fil_flush_file_spaces() would be very slow. fil_flush_file_spaces(): Only flush unflushed file spaces. fil_space_t, fil_system_t: Add a list of unflushed spaces. #15991: "innodb-file-per-table + symlink database + rename = cr" os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock. Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile. Add diagnostics for the case that hash node pointers to the page remain. btr_search_info_update_hash(), btr_search_info_update_slow(): Document the parameter "info" as in/out. #16814: "SHOW INNODB STATUS format error in LATEST FOREIGN KEY ERROR section" Add a missing newline to the LAST FOREIGN KEY ERROR section in SHOW INNODB STATUS output. dict_foreign_error_report(): Always print a newline after invoking dict_print_info_on_foreign_key_in_create_format(). #16827: "Better InnoDB error message if ibdata files omitted from my.cnf" #17126: "CHECK TABLE on InnoDB causes a short hang during check of adaptive hash" CHECK TABLE blocking other queries, by releasing the btr_search_latch periodically during the adaptive hash table validation. #17405: "Valgrind: conditional jump or move depends on unititialised values" buf_block_init(): Reset magic_n, buf_fix_count and io_fix to avoid testing uninitialized variables.	20 years ago
