      Apply the following InnoDB snapshots: · baddc4e9

      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.

      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 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.
