      Applied InnoDB 5.1 snapshot ss787. · c488e4b9
      tsmith@maint1.mysql.com authored
      Bugs fixed:
      - Bug #20791    valgrind errors in InnoDB
        Remove Valgrind warning of Bug #20791 : in new database
        creation, we read the doublewrite buffer magic number from
        uninitialized memory; the code worked because it was extremely
        unlikely that the memory would contain the magic number
      - Bug #21784    DROP TABLE crashes 5.1.12-pre if concurrent
        queries on the table
        remove update_thd() in ::store_lock()
      
      
      Also includes numerous coding style fixes, etc.  See file-level
      comments for details.

       Fixed BUG#19542 "InnoDB doesn't increase the Handler_read_prev couter".
       Fixed BUG#19609 "Case sensitivity of innodb_data_file_path gives stupid error".
       Fixed BUG#19727 "InnoDB crashed server and crashed tables are ot recoverable".
       Also:
       * Remove remnants of the obsolete concept of memoryfixing tables and indexes.
       * Remove unused dict_table_LRU_trim().
       * Remove unused 'trx' parameter from dict_table_get_on_id_low(),
         dict_table_get(), dict_table_get_and_increment_handle_count().
       * Add a normal linked list implementation.
       * Add a work queue implementation.
       * Add 'level' parameter to mutex_create() and rw_lock_create().
         Remove mutex_set_level() and rw_lock_set_level().
       * Rename SYNC_LEVEL_NONE to SYNC_LEVEL_VARYING.
       * Add support for bound ids in InnoDB's parser.
       * Define UNIV_BTR_DEBUG for enabling consistency checks of
         FIL_PAGE_NEXT and FIL_PAGE_PREV when accessing sibling
         pages of B-tree indexes.
         btr_validate_level(): Check the validity of the doubly linked
         list formed by FIL_PAGE_NEXT and FIL_PAGE_PREV.
       * Adapt InnoDB to the new tablename to filename encoding in MySQL 5.1.
         ut_print_name(), ut_print_name1(): Add parameter 'table_id' for
         distinguishing names of tables from other identifiers.
         New: innobase_convert_from_table_id(), innobase_convert_from_id(),
              innobase_convert_from_filename(), innobase_get_charset.
         dict_accept(), dict_scan_id(), dict_scan_col(), dict_scan_table_name(),
         dict_skip_word(), dict_create_foreign_constraints_low(): Add
         parameter 'cs' so that isspace() can be replaced with my_isspace(),
         whose operation depends on the connection character set.
         dict_scan_id(): Convert identifier to UTF-8.
         dict_str_starts_with_keyword(): New extern function, to replace
         dict_accept() in row_search_for_mysql().
         mysql_get_identifier_quote_char(): Replaced with innobase_print_identifier().
         ha_innobase::create(): Remove the thd->convert_strin() call. Pass the
         statement to InnoDB in the connection character set and let InnoDB
         convert the identifier to UTF-8.
       * Add max_row_size to dict_table_t.
       * btr0cur.c
         btr_copy_externally_stored_field(): Only set the 'offset' variable
         when needed.
       * buf0buf.c
         buf_page_io_complete(): Write to the error log if the page number or
         the space id o the disk do not match those in memory. Also write to
         the error log if a page was read from the doublewrite buffer. The
         doublewrite buffer should be only read by the lower-level function
         fil_io() at database startup.
       * dict0dict.c
         dict_scan_table_name(): Remove fallback to differently encoded name
         when the table is not found. The encoding is handled at a higher level.
       * ha_innodb.cc
         Increment statistic counter in ha_innobase::index_prev() (bug 19542).
         Add innobase_convert_string wrapper function and a new file
         ha_prototypes.h.
         innobase_print_identifier(): Remove TODO comment before calling
         get_quote_char_for_identifier(). That function apparently assumes
         the identifier to be encoded in UTF-8.
       * ibuf0ibuf.c|h
         ibuf_count_get(), ibuf_counts[], ibuf_count_inited(): Define these
         only #ifdef UNIV_IBUF_DEBUG. Previously, when compiled without
         UNIV_IBUF_DEBUG, invoking ibuf_count_get() would crash InnoDB.
         The function is only being called #ifdef UNIV_IBUF_DEBUG.
       * innodb.result
         Adjust the results for changes in the foreign key error messages.
       * mem0mem.c|h
         New: mem_heap_dup(), mem_heap_printf(), mem_heap_cat().
       * os0file.c
         Check the page trailers also after writing to disk. This improves
         chances of diagnosing bug 18886.
         os_file_check_page_trailers(): New function for checking that the
         two copies of the LSN stamped on the page match.
         os_aio_simulated_handle(): Call os_file_check_page_trailers()
         before and after os_file_write().
       * row0mysql.c
         Move trx_commit_for_mysql(trx) calls before calls to
         row_mysql_unlock_data_dictionary(trx) (bug 19727).
       * row0sel.c
         row_fetch_print(): Handle SQL NULL values without crashing.
         row_sel_store_mysql_rec(): Remove useless call to rec_get_nth_field
         when handling an externally stored column.
         Fetch externally stored fields when using InnoDB's internal SQL
         parser.
         Optimize BLOB selects by using prebuilt->blob_heap directly instead
         of first reading BLOB data to a temporary heap and then copying it
         to prebuilt->blob_heap.
       * srv0srv.c
         srv_master_thread(): Remove unreachable code.
       * srv0start.c
         srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and
         'g' as abbreviations of megabyte and gigabyte (bug 19609).
         srv_parse_megabytes(): New fuction.
       * ut0dbg.c|h
         Implement InnoDB assertions (ut_a and ut_error) with abort() when
         the code is compiled with GCC 3 or later on other platforms than
         Windows or Netware. Also disable the variable ut_dbg_stop_threads
         and the function ut_dbg_stop_thread() i this case, unless
         UNIV_SYC_DEBUG is defined. This should allow the compiler to
         generate more compact code for assertions.
       * ut0list.c|h
         Add ib_list_create_heap().

      Applied innodb-5.1-ss475 snapshot. · 780f80be
      aivanov@mysql.com authored
      * 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().
