      message:
      Bug#35164: Large number of invalid pthread_attr_setschedparam calls
      Bug#37536: Thread scheduling causes performance degradation at low thread count
      Bug#12702: Long queries take 100% of CPU and freeze other applications under Windows
      
      The problem is that although having threads with different priorities
      yields marginal improvements [1] in some platforms [2], relying on some
      statically defined priorities (QUERY_PRIOR and WAIT_PRIOR) to play well
      (or to work at all) with different scheduling practices and disciplines
      is, at best, a shot in the dark as the meaning of priority values may
      change depending on the scheduling policy set for the process.
      
      Another problem is that increasing priorities can hurt other concurrent
      (running on the same hardware) applications (such as AMP) by causing
      starvation problems as MySQL threads will successively preempt lower
      priority processes. This can be evidenced by Bug#12702.
      
      The solution is to not change the threads priorities and rely on the
      system scheduler to perform its job. This also enables a system admin
      to increase or decrease the scheduling priority of the MySQL process,
      if intended.
      
      Furthermore, the internal wrappers and code for changing the priority
      of threads is being removed as they are now unused and ancient.
      
      1. Due to unintentional side effects. On Solaris this could artificially
      help benchmarks as calling the priority changing syscall millions of
      times is more beneficial than the actual setting of the priority.
      
      2. Where it actually works. It has never worked on Linux as the default
      scheduling policy SCHED_OTHER only accepts the static priority 0.

      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.

      aivanov@mysql.com authored
       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().

        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.

      enabled. Fixed a few bugs and found a few possible bugs, which
      I hope Heikki will check. Comments needs to be fixed too. Some
      while() functions should be changed to do ... until for documenting
      purposes, because some of them must and will be processed at least
      once, or a variable would be used uninitialized.
      
      Regards,
      Jani
