      branches/5.1: Fix a bug in multi-table semi-consistent reads.
      Remember the acquired record locks per table handle (row_prebuilt_t)
      rather than per transaction (trx_t), so that unlock_row should successfully
      unlock all non-matching rows in multi-table operations.
      This deficiency was found while investigating Bug #39320.

      tsmith@ramayana.hindu.god authored
      Bug #16979: AUTO_INC lock in InnoDB works a table level lock
        Add a table level counter that tracks the number of AUTOINC locks that are
        pending and/or granted on a table. We peek at this value to determine whether
        a transaction doing a simple INSERT in innodb_autoinc_lock_mode = 1, needs to
        acquire the AUTOINC lock or not. This change is related to Bug# 16979.
      Bug #27950: Duplicate entry error in auto-inc after mysqld restart
        We check whether the AUTOINC sub-system has been initialized (first) by
        holding the AUTOINC mutex and if initialization is required then we
        initialize using our normal procedure.

      innodb-5.1-ss1340
      
      Fixes:
      - Bug #21409: Incorrect result returned when in READ-COMMITTED with query_cache ON
        At low transaction isolation levels we let each consistent read set
        its own snapshot.
      
      - Bug #23666: strange Innodb_row_lock_time_% values in show status; also millisecs wrong
        On Windows ut_usectime returns secs and usecs relative to the UNIX
        epoch (which is Jan, 1 1970).
      
      - Bug #25494: LATEST DEADLOCK INFORMATION is not always cleared
        lock_deadlock_recursive(): When the search depth or length is exceeded,
        rewind lock_latest_err_file and display the two transactions at the
        point of aborting the search.
      
      - Bug #25927: Foreign key with ON DELETE SET NULL on NOT NULL can crash server
        Prevent ALTER TABLE ... MODIFY ... NOT NULL on columns for which
        there is a foreign key constraint ON ... SET NULL.
      
      - Bug #26835: Repeatable corruption of utf8-enabled tables inside InnoDB
        The bug could be reproduced as follows:
      
        Define a table so that the first column of the clustered index is
        a VARCHAR or a UTF-8 CHAR in a collation where sequences of bytes
        of differing length are considered equivalent.
      
        Insert and delete a record.  Before the delete-marked record is
        purged, insert another record whose first column is of different
        length but equivalent to the first record.  Under certain conditions,
        the insertion can be incorrectly performed as update-in-place.
      
        Likewise, an operation that could be done as update-in-place can
        unnecessarily be performed as delete and insert, but that would not
        cause corruption but merely degraded performance.

       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().

        - 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().

        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.
